　　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.
