Negative pressure suction pump suction type pneumatic conveying equipment

Introduction of negative pressure suction pump <br /> The negative pressure suction pump and suction pneumatic conveying equipment device system produced by Ruiguang Machinery have unique wear-resistant parts structure and materials to extend the life of suction pump. The vacuum negative pressure generated by the vacuum pump is used as the conveying power. The material is sucked into the conveying pipeline, and the material and gas separator is used to separate the material and gas. After the material is separated, the material is discharged into the receiving bin by electric air lock valve under the action of gravity. Operation, reduce the occurrence of security accidents and reduce the operating costs of the enterprise. Negative pressure pneumatic conveying can be designed according to the needs of users. Its other forming equipment is ship unloader, negative pressure pneumatic conveying-unloading machine, and dock negative pressure suction pump.

Negative pressure pneumatic conveying system (also known as negative pressure air conveying system or negative pressure air conveying system) is the vacuum generated by high pressure centrifugal fan (or Roots vacuum pump), which sucks the bulk powder and granular materials into the designated container with negative pressure air flow. (Silo), vacuum vacuum pressure collection system composed of Ruiguang negative pressure suction pneumatic conveying device, which is especially suitable for short distance, high material temperature and multi-point discharge systems.

The bulk material suction machine is composed of a suction nozzle, a hydraulic suction arm, a separation and discharge device, a roots blower (vacuum pump), and an electronic control system. The materials can be sent directly to the bulk material storage (storage) directly or through the conveying machinery. The pneumatic conveying system for bulk materials consists of negative pressure pneumatic conveying equipment (suction nozzle, hydraulic suction arm, separation device, roots blower or vacuum pump) and positive pressure pneumatic conveying equipment (bin pump, combined pump, air compressor) and electronic control system. composition.

Negative pressure suction pneumatic conveying principle
Negative pressure suction-type pneumatic conveying fluidized bin uses air to make the fly ash particles fully fluidized, so that the fly ash can enter the negative pressure ash suction positive pressure conveying pipeline smoothly. The interior of the negative pressure ash suction fluidization bin is composed of two porous thin steel plates, and a breathable layer is sandwiched between the upper and lower porous plates. The perforated plates inside the entire fluidization bin are arranged at a certain slope (4% -10%). Fly ash enters the combined pump from the separator, and enters the fluidization bin from the combined pump, and the feeding equipment is added to the breathable layer of the feeding opening of the upper casing. The air enters the lower casing from the fluidization bin, and passes through the breathable layer along the fluidization bin to fluidize the fly ash. Feeding into the conveying machinery or entering into the positive pressure conveying equipment, the positive pressure generated by the air compressor or the roots fan passes the feeding pipeline to send the material into the bulk material warehouse (warehouse). The clean air is discharged from the upper part of the separator through the exhaust duct, and is discharged into the atmosphere from the roots of the Roots blower (vacuum pump).

Components of suction-type pneumatic conveying equipment <br /> The main components of the negative pressure suction-feeding device are separator, suction nozzle (fixed suction nozzle and movable suction nozzle), unloader, vacuum pump, valve and pipe fittings, Control system, etc., suitable for short and medium distance transportation of powdery materials. Because the transportation process is completed in a closed negative pressure pipeline, no leakage and pollution will occur on the transmission line, and it is especially suitable for the transportation of hazardous substances with strict leakage pollution requirements. Conveying system can feed single point or multiple points, the process layout is flexible and convenient.

Advantages of the negative pressure suction pneumatic conveying device system <br /> The pressure in the conveying pipe is lower than the ambient pressure, and the dust does not leak outward. It is a better choice for conveying toxic materials. It is often used for ship unloading, vacuum loading, cleaning, etc. application. Suitable for multi-point to one-point conveying. The conveying line is in the state of negative pressure pipeline, and there is no leakage or pollution during the conveying process; the conveying state is uniform and continuous, and the conveying capacity can be adjusted; the air source device adopts dry negative pressure air source, which is simple and reliable; Pulse blowing, compact structure, high separation efficiency; the nozzle device can be specially designed according to different applications and process requirements; the equipment configuration of the conveyor system is simple, the system investment is small; the system maintenance is low, and the maintenance is convenient.

Negative pressure suction classification
1. Negative pressure suction direct loading type;
2. Negative pressure suction mechanical conveying type;
3. Negative pressure mixed pneumatic conveying type.

Ruiguang Machinery Factory is a professional manufacturer and installer of pneumatic conveying equipment. This negative pressure suction equipment is a suction pump equipment carefully developed by Ruiguang Machinery. Ruiguang undertakes various kinds of bulk material negative pressure unloading projects in rivers and seaports. The pressure unloading ship system can be divided into fixed, track-movable, truck-mounted and ship-mounted, etc., and can be designed according to the specific requirements of customers.
