High Pressure Transport Pneumatic Conveyor Bin Pump Used In Slag / Cement / Fly Ash

High Pressure Transport Pneumatic Conveyor Bin Pump Used in Slag /Cement / Fly Ash

The silo pneumatic conveying pump adopts a positive pressure pneumatic conveying method to transport powdered materials, and is widely used in the transportation of materials such as fly ash, cement, cement raw materials, and mineral powder in power plants. Transportation pipelines can be flexibly arranged according to terrain conditions to achieve centralized, dispersed, high altitude, and long-distance transportation. The transportation process is not affected by natural conditions, ensuring that materials are not affected by moisture and are environmentally friendly and pollution-free. This equipment adopts a PLC control system, which can be automatically or manually controlled. After long-term practical operation, it has been proven that the equipment has stable performance, reliable quality, and no dust pollution during transportation, making it an ideal pneumatic conveying equipment.

There are two discharge methods for bin pumps, among which bottom discharge is the most commonly used method. The materials in the tank can be fluidized through the conical surface inflation groove, nozzle jet, or other methods; Setting a fluidized inflation plate (layer) at the bottom allows the material to be discharged from the upper part of the tank. The distribution of transported gas on different input planes in the tank depends on the properties of the transported material.

Warehouse pump conveying is a discontinuous conveying process. The figure shows a standard compartment pump with inlet and outlet valves, material conveying pipelines, air input pipelines, and a silo. Before feeding into the silo pump, the silo is filled with the conveyed material, and all valves are closed. The entire work process is as follows:

(1) Open the feed valve and exhaust valve, and feed the silo pump at atmospheric pressure until the horizontal level gauge sends a signal indicating full silo;

(2) Close the feed valve and exhaust valve, then open the high-pressure air valve to pressurize the tank;

(3) When the operating pressure is reached, open the conveying air valve and discharge valve, and the material begins to be conveyed;

(4) The conveying end is displayed by the pressure switch, level gauge, or time relay. At this time, close the high-pressure air valve and discharge valve, so that all compressed air is used to clean the conveying pipeline; Simultaneously open the exhaust valve to reduce the pressure inside the tank to normal pressure.

After one work cycle is completed, the other cycle continues.

The working principle of the electric plug valve is to receive control commands, electrically open the plug valve, and carry out ash discharge work.
