Low Power Consumption Positive Pressure Dense Phase Pump Pneumatic Conveying

Low Power Consumption Positive Pressure Dense Phase Conveying Pump Fly Ash Silo Pump

Description

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, mineral powder, etc. in power plants. The transportation pipeline can be flexibly arranged according to the terrain conditions, achieving 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. It is an ideal pneumatic conveying equipment.

In terms of positive pressure dense phase intermittent pneumatic conveying, the company has always been committed to theoretical research and engineering practice experience summary of pneumatic conveying systems, focusing on breaking through the key technologies of long-distance, high production, low energy consumption, and low wear in the pneumatic conveying process. The core product is the PCD type positive pressure dense phase pneumatic conveying silo pump, while providing systematic, standardized, and refined engineering design and technical services. To meet the needs of different customers, we create the best design plan based on parameters such as material properties, conveying distance, conveying capacity, receiving warehouse capacity, dust removal capacity, and geographical conditions. Each equipment is manufactured through qualified inspection, and each pneumatic conveying system has its own design features, allowing customers to truly experience the intelligent management and economic benefits brought by advanced technology products.

Application Area

PCD pneumatic conveying equipment and systems have been widely used in industries such as building materials, chemicals, mining, power, and metallurgy. The conveying materials include cement, raw materials, fly ash, hydrated lime, dry discharged calcium carbide slag, slag powder, steel slag powder, coal powder, aluminum oxide powder, bauxite powder, phosphorus powder, pyrophyllite powder, and organic silicon powder.

Working principle of silo pump:
The silo pump conveying is a discontinuous conveying process. It is composed of inlet and outlet valves, material conveying pipelines, air input pipelines, and storage tanks. Before the feeding of the pneumatic conveying silo pump, the silo is filled with the conveyed material, and all valves are closed. The entire working process is as follows:

① Open the feed valve and exhaust valve, and the pneumatic conveying bin pump will feed at atmospheric pressure until the level gauge sends a full bin indication signal;
② Close the feed valve and exhaust valve, and then open the high-pressure air valve to pressurize the tank;
③ When the operating pressure is reached, open the delivery air valve and discharge valve, and the material begins to be delivered;
④ The conveying end is displayed by the pressure switch, level gauge, or time relay. At this point, 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.
