The bin pump, also known as the bin type pneumatic conveying pump and the bin type pump, adopts the high-pressure dense phase pneumatic conveying mode of air compressor to convey powder and granular materials, which is suitable for the conveying of powder and granular materials. The conveying pipeline can be arranged according to the specific terrain to realize centralized, decentralized, high-altitude and long-distance transportation. The equipment is equipped with an automatic console, which can realize manual and automatic control. The automatic control adopts the form of PLC automatic control transmission. With stable performance, reliable quality and no dust pollution, it is an ideal pneumatic conveying equipment.

According to different materials and working conditions, the bin pump feeding system is divided into middle lead type, down lead type and up lead type. The bin pump tank is a pressure vessel, which needs to be regularly inspected for safety to ensure normal use.

The working process of the bin pump is divided into four stages:

Feeding stage: the feeding valve and exhaust valve are opened, and the materials freely fall into the pump body. When the material is full, the material level gauge sends a signal, and the feeding valve and exhaust valve automatically close to complete the feeding process;

Fluidization and pressurization stage: open the inlet valve, the compressed air enters the upper and bottom of the pump body, pressurizes the upper part, and the lower part of the air diffuses through the fluidized bed, so that the material is in a fluidization state, and the pressure in the pump rises at the same time;

Conveying stage: when the pressure in the pump reaches a certain value, the pressure gauge or pressure switch will send a signal, the discharge valve will automatically open, the fluidization of the materials on the fluidized bed will be strengthened, the conveying will begin, and the materials in the pump will gradually decrease. At this time, the materials on the fluidized bed will always be in the state of fluidization and conveying at the same time;

Purging stage: when the material in the pump is delivered and the pressure drops to the pipeline resistance, the pressure gauge or pressure switch will send a signal, the ventilation will continue for a certain time, the compressed air will clean the pipeline, then the inlet valve will be closed, and the discharge valve will be closed and the inlet valve will be opened at a certain interval to complete a conveying cycle.

The system selects the appropriate conveying tank style according to the user's specific materials and site layout to meet the site working conditions of long-distance and large conveying capacity.
