氣力輸送又被稱為氣體流動輸送，是運用氣體機械能將物料在封閉管路中順著氣體流動方位輸送的一種技術性。氣力輸送系統可以有效地運用車間室內空間，而且耗能低，噪聲小，還不容易對自然環境產生危害。今日咱們就來了解一下氣力輸送中央供料系統由什么設備構成?

　　氣力輸送中央供料系統關鍵有送料系統、氣動閥門系統、輸送管道系統、除灰系統、料斗系統及其操縱系統構成，可以完成輸送、計量檢定、復混肥、干躁、除灰等作用，在其中，不一樣的一部分充分發揮著不一樣的功效:

　　送料系統:

　　供料系統關鍵的功效便是提供物料，讓其在密閉的系統中完成輸送，對于不一樣的物料輸送規定,可以選用差異的送料系統。翔瑞的供料系統有旋轉供料器、磁力泵、倉式泵、噴嘴流量計等設備。

　　管道系統:

　　管路系統是完成送料系統與氣力輸送系統聯接的管道，關鍵目標是完成物料的長距離輸送。當物料對氣動閥門有沽凈規定的情況下，我們可以在管道系統中**如空氣過濾網、除灰設備等氣動閥門凈化處理設備。管路的選材與設計方案會對物料的輸送高效率導致立即的危害，因而在制定前期就需要更加考慮到。

　　備料系統:

　　收料系統*首要的設備是料斗，它經常是角錐或是是囫錐狀的結構，可以具有臨時儲存物料和推廣物料的功效，料斗設計方案必須考慮到不一樣物料在儲存及倒料全過程中的問題和物料的流動性方式。翔瑞的料斗有存儲料斗、作用力復混肥料斗、減壓蒸餾倉、制冷倉、正中間拌和倉等。

　　除灰系統:

　　除塵系統關聯到全部氣力輸送系統的排出是不是能實現環境保護規定，提議每位老總依據物料不一樣的料性，不同的比例，來實現挑選，要不然非常容易由于設計方案不配對導致系統排出不合格，因此應當選擇專業生產廠家，可依據具體需要挑選恰當合適的除灰設備。

　　操縱系統:

　　控制系統主要是完成對中央供料系統的調整操縱，選用可編式控制板實現操縱，可以配自動控制系統電機控制系統，完成全部系統沒有人操縱及相互配合PLC白動操縱。根據系統來集中控制系統系統的除灰、輸送.警報、常見故障泊車等工作中，可以更便捷更可靠地對開展實時控制。

　　氣力輸送中央供料系統的優點

　　一、室內空間的靈活運用

　　氣力輸送設備簡易、可以有效、靈便地運用車間室內空間，依靠二類壓力容器避開大中型設備、房屋建筑等阻礙物。而且可以完成多一點物料集中化輸送，或是一點向多點分散輸送。

　　二、適用范圍廣

　　氣力輸送系統適用小顆粒粉體物料的持續性輸送，與此同時也適用與間斷性將很多顆粒物物料從散運油罐車、鐵路貨車、海上海船等設備運輸到儲倉。

　　三、密閉式自然環境

　　輸送線路上選用密閉式管路開展輸送，安全系數高，著火和發生爆炸的風險性小，而且可以維持工業區清潔衛生，降低煙塵散出產生的空氣污染。

　　四、可完成遠距離大空間輸送

　　氣力輸送比較遠可達一公里以上，工作能力每鐘頭可達上百噸/小時，沿路僅有管路，布局靈便，不占室內空間，實際操作檢修簡易。

　　五、易完成自動化技術

　　氣力輸送中央供料系統中選用的羅茨機械泵(羅茨風機)、總流量調節器和信號接收器等設備的實際操作與液體設備的實際操作相似之處非常大。因而可以選用同一個核心控制面板實際操作，易完成自動化生產。

　　氣力輸送相對性于機械設備輸送高效率要高，而且合理性高、布局靈便。氣力輸送技術性并沒有統一的規范，關鍵是設計師工作經驗累積的需求較高。氣力輸送設備防污抗氧化效果非常的好;有益于公司完成專業化和自動化技術，可緩解勞動效率，節約人力資源，減少人力成本，降低空氣污染;在輸送全過程中，可以一起開展多種多樣加工工藝實際操作，如混和、破碎、篩分、干躁、制冷;避免物料返潮、環境污染或滲入臟物等優勢，因此在鑄造、冶金工業、化工廠、裝飾建材、糧油加工等機構都獲得運用。

　　它的具體不足之處是驅動力耗費比較大;設備(主要是分離設備通道)和管路(主要是彎管)損壞較快，假如設計方案、工程施工或運行不合理，則很容易導致物料堆積，以至阻塞，使輸送終斷;不適合輸送環境濕度大、粘性大或易碎的物料等。

　　氣力輸送設備一般由受加料器(如喉嚨、真空吸盤、發送器等)、輸送管、風道、分離設備(常見的有容量式和旋風式二種)、鎖氣器(常見的有翻平板式和管式二種，既可做為喂加料器，又可做為卸料器)、除塵設備和離心風機(如離心式風機、羅茨風機、水環式真空泵、空氣壓縮機等)等設備和構件構成。

　　氣力輸送中央供料設備操作步驟

　　設備打開前先查驗設備是不是充注機油，設備各部件是否完好無損，羅茨離心風機及旋轉供料器的正反轉，輸送管路是不是順暢。

　　打開方法:先將羅茨離心風機或羅茨泵打開，觀查離心風機出入口氣壓表工作壓力，管路在通暢情況下工作壓力幾乎為零;隨后打開**臺旋轉供料器，*終把上邊的手動插板閥漸漸地開啟，伴隨著閘板閥的開啟物料會掉入旋轉供料器隨后進到輸送管路，氣壓表會出現起伏。依據物料的流通性和氣壓表的表明，可調節手動閥門的開啟度操縱下料量。隨時隨地觀查氣壓表的轉變。

　　有兩部供加料器的輸送路線在**臺旋轉供料器物料輸送結束后，關掉**臺旋轉供料器，1-2min后，管路中物料輸送結束，再打開第二臺旋轉供料器，先后運作。

　　終止方法:先將手動插板閥關掉(假如設備短期內終止得話可以不用關掉手動插板閥)，隨后關掉旋轉供料器，觀查離心風機出入口氣壓表，待氣體壓力為民航空管工作壓力時(間距約Ⅰmin)隨后關掉羅茨風機。

　　氣力輸送可以節約能源和控制成本，可以協助公司**限度地完成盈利，是每一個公司的必然趨勢。氣力輸送的形式有很多種多樣，挑選適宜的氣力輸送方式及設備是確保公司生產過程合理性、輸送高效率放大的重要。

　　Pneumatic conveying, also known as gas flow conveying, is a kind of technology that uses gas mechanical energy to convey materials along the direction of gas flow in a closed pipeline. The pneumatic conveying system can effectively use the indoor space of the workshop, and has low energy consumption, low noise and is not easy to harm the natural environment. Today, let's take a look at what equipment constitutes the pneumatic conveying central feeding system?

　　The central feeding system of pneumatic conveying is composed of feeding system, pneumatic valve system, conveying pipeline system, ash removal system, hopper system and its control system, which can complete the functions of conveying, metrological verification, compound fertilizer, dryness and ash removal. Among them, different parts give full play to different effects:

　　Feeding system:

　　The key function of the feeding system is to provide materials to complete the transportation in a closed system. For different material transportation regulations, different feeding systems can be selected. Xiangrui's feeding system includes rotating feeder, magnetic pump, bin pump, nozzle flowmeter and other equipment.

　　Piping system:

　　The pipeline system is the pipeline connecting the feeding system and the pneumatic conveying system, and the key goal is to complete the long-distance transportation of materials. When there are regulations on the net selling of pneumatic valves for materials, we can improve the purification treatment equipment of pneumatic valves such as air filter screen and ash removal equipment in the pipeline system. The material selection and design scheme of pipeline will cause immediate harm to the high efficiency of material transportation, so it needs to be taken into account in the early stage of formulation.

　　Material preparation system:

　　The most important equipment of the receiving system is the hopper. It is often a pyramid or a whole cone structure, which can temporarily store and promote materials. The hopper design scheme must take into account the problems of different materials in the whole process of storage and dumping and the fluidity of materials. Xiangrui's hoppers include storage hopper, acting compound fertilizer hopper, decompression distillation bin, refrigeration bin, central mixing bin, etc.

　　Ash handling system:

　　The dust removal system is related to whether the discharge of all pneumatic conveying systems can realize the provisions of environmental protection. It is suggested that each boss choose according to the different material properties and different proportions of materials. Otherwise, it is very easy to cause unqualified system discharge due to mismatched design schemes. Therefore, professional manufacturers should be selected, and appropriate ash removal equipment can be selected according to specific needs.

　　Control system:

　　The control system mainly completes the adjustment and operation of the central feeding system, selects the programmable control board to realize the operation, and can be equipped with the automatic control system and motor control system to complete the unmanned operation of all systems and cooperate with each other in PLC white operation. Centralized control of ash removal and transportation according to the system In alarm, common fault parking and other work, real-time control can be carried out more conveniently and reliably.

　　Advantages of pneumatic conveying central feeding system

　　1、 Flexible use of indoor space

　　Pneumatic conveying equipment is simple, which can effectively and conveniently use the indoor space of the workshop, and rely on class II pressure vessels to avoid obstacles such as large and medium-sized equipment, houses and buildings. Moreover, it can complete the centralized transportation of more materials, or the decentralized transportation from one point to many points.

　　2、 Wide application range

　　The pneumatic conveying system is suitable for the continuous transportation of small particle powder materials. At the same time, it is also suitable for and intermittent transportation of many particle materials from bulk oil tank trucks, railway trucks, sea ships and other equipment to storage warehouses.

　　3、 Closed natural environment

　　The closed pipeline is selected for transmission on the transmission line, which has high safety factor and low risk of fire and explosion. In addition, it can maintain the cleanliness of the industrial area and reduce the air pollution caused by the emission of smoke and dust.

　　4、 It can complete long-distance and large space transportation

　　Pneumatic conveying is far away, up to more than one kilometer, and the working capacity can reach hundreds of tons / hour. There are only pipelines along the road, the layout is convenient, does not occupy indoor space, and the actual operation and maintenance are simple.

　　5、 Easy to complete automation technology

　　The actual operation of roots mechanical pump (roots blower), total flow regulator and signal receiver selected in the central feeding system of pneumatic conveying is very similar to that of liquid equipment. Therefore, the same core control panel can be selected for actual operation, which is easy to complete automatic production.

　　Compared with mechanical equipment, pneumatic conveying has high efficiency, high rationality and convenient layout. There is no unified specification for pneumatic conveying technology. The key is the high demand for designers' accumulated work experience. The antifouling and antioxidant effect of pneumatic conveying equipment is very good; It is beneficial for the company to complete specialization and automation technology, alleviate labor efficiency, save human resources, reduce labor costs and reduce air pollution; In the whole process of transportation, various processing processes can be carried out together, such as mixing, crushing, screening, drying and refrigeration; It has the advantages of avoiding material moisture return, environmental pollution or infiltration of dirt. Therefore, it has been used in foundry, metallurgical industry, chemical plant, decorative building materials, grain and oil processing and other institutions.

　　Its specific deficiency is that the driving force is relatively expensive; The equipment (mainly separation equipment channel) and pipeline (mainly elbow) are damaged quickly. If the design scheme, engineering construction or operation are unreasonable, it is easy to lead to material accumulation, even blockage and final interruption of transportation; It is not suitable for conveying materials with high humidity, high viscosity or fragile.

　　Pneumatic conveying equipment is generally composed of feeder (such as throat, vacuum suction cup, transmitter, etc.), conveying pipe, air duct, separation equipment (common capacity type and cyclone type), air lock (common turnover plate type and pipe type, which can be used as both feeder and discharger), dust removal equipment, centrifugal fan (such as centrifugal fan, Roots fan, water ring vacuum pump, air compressor, etc.).

　　Operation steps of pneumatic conveying central feeding equipment

　　Before opening the equipment, check whether the equipment is filled with oil, whether all parts of the equipment are intact, whether the forward and reverse rotation of roots centrifugal fan and rotary feeder, and whether the conveying pipeline is smooth.

　　Opening method: first open the roots centrifugal fan or roots pump, observe the working pressure of the air pressure gauge at the inlet and outlet of the centrifugal fan, and the working pressure is almost zero when the pipeline is unobstructed; Then open the first rotary feeder, and finally gradually open the upper manual plug valve. With the opening of the gate valve, the material will fall into the rotary feeder and then into the conveying pipeline, and the barometer will fluctuate. According to the fluidity of materials and the indication of barometer, the opening degree of manual valve can be adjusted to control the blanking amount. Observe the change of barometer anytime and anywhere.

　　For the conveying route of two feeders, after the material conveying of the first rotary feeder is completed, turn off the first rotary feeder. After 1-2min, the material conveying in the pipeline is completed, and then turn on the second rotary feeder to operate successively.

　　Termination method: first turn off the manual gate valve (if the equipment is terminated in a short time, it is not necessary to turn off the manual gate valve), then turn off the rotary feeder, observe the air pressure gauge at the inlet and outlet of the centrifugal fan, and then turn off the Roots fan when the gas pressure is the working pressure of the civil aviation air duct (the spacing is about I min).

　　Pneumatic conveying can save energy and control costs, and help companies maximize profits. It is the inevitable trend of every company. There are many forms of pneumatic conveying. Selecting appropriate pneumatic conveying methods and equipment is an important way to ensure the rationality of the company's production process and the high efficiency of conveying.
