Reliable Dust-free Conveying Dilute Phase Pneumatic Conveying Jet Pump

Description

The pneumatic conveying equipment series can be widely used for the transportation of powder and granular materials in industries such as cement, petrochemical, power, and metallurgy. Due to its flexible layout, small space occupied by pneumatic conveying equipment, and the ability to avoid existing equipment and buildings, it is particularly suitable for the renovation and expansion projects of cement plants. At present, the pneumatic conveying system is mostly used for raw materials entering the kiln or homogenization silo, and coal powder entering the kiln or decomposition furnace in the new dry process cement plant.

Application Area
The PJP type positive pressure dilute phase pneumatic conveying jet pump is a low-pressure, dilute phase, and continuous pneumatic conveying equipment suitable for situations where the conveying volume is not large and the conveying distance is medium. It can be widely used in industries such as building materials, chemicals, electricity, grain, metallurgy, casting, etc. The conveying materials include cement, raw materials, fly ash, hydrated lime, slag powder, steel slag powder, coal powder, aluminum oxide powder, phosphorus powder, pyrophyllite powder, and organic silicon powder.

PJP Type Positive Pressure Dilute Phase Pneumatic Conveying Jet Pump

Working Principle
The PJP jet pump pneumatic conveying system consists of a PJP jet pump, a pneumatic butterfly valve, a pump top compartment, a manual spiral gate, and a compressed air supply device. The main source of compressed air is the Roots blower. Powder and granular materials enter the PJP jet pump through manual spiral gates, pump top bins, and pneumatic butterfly valves. When compressed air for transportation passes through the nozzle inside the PJP type jet pump box, the high-speed airflow generated creates a negative pressure state inside the PJP type jet pump box. The materials in the top compartment of the pump are easily mixed with the high-speed airflow. Then, when the material gas mixture passes through the expansion pipe of the PJP type jet device, the kinetic energy of the high-speed airflow is converted into static pressure energy, thereby conveying powder and granular materials to the terminal through the conveying pipeline. The manual spiral gate of the PJP jet pump is used for debugging and maintenance, and the pneumatic butterfly valve is used for automatically closing when the transportation of powder and granular materials is suspended or the system pressure is abnormal.

When the PJP type positive pressure dilute phase pneumatic conveying jet pump is installed at the bottom of the silo (warehouse) to transport materials using the pressure of the materials in the silo (warehouse), changes in the height of the materials in the silo (warehouse) will cause corresponding changes in the material conveying speed. Therefore, the conveying energy of the materials depends on the height of the materials in the silo (warehouse).

When the PJP type positive pressure dilute phase pneumatic conveying jet pump is equipped with a locking device, the conveying capacity of the material depends on the locking capacity of the locking device.
