Husk and powder metering and air conveying device and operation method thereof

Abstract

The invention provides a husk and powder metering and air conveying device and an operation method of the husk and powder metering and air conveying device. A machine shell of the husk and powder metering and air conveying device comprises a feeding portion, a metering portion, a transferring portion and an air conveying portion. The feeding portion comprises a hopper. The metering portion comprises a helical rod. Helical blades are wound around the helical rod and include a large-section blade and a small-section blade. The helical rod is driven by a metering motor through a speed reducer tobe connected with other parts, and a counter is connected to the speed reducer. The transferring portion comprises a rotating propeller. The rotating propeller comprises a central shaft and multiple propeller blades. The central shaft is driven by a transferring motor to be connected with other parts. Rubber blades are fixedly installed on the outer edges of the propeller blades, bent edges are arranged on the edges of the rubber blades and make contact with the cylindrical machine shell, and the bent sharp corners of the bent edges face the rotating direction of the rotating propeller. The air conveying portion comprises an air conveying pipeline. A material receiving opening is formed in the top of the air conveying pipeline and located below the rotating propeller. A pipe opening formedin one end of the air conveying pipeline serves as an air inlet, a high pressure fan is connected to the air inlet in a sealing mode, and a pipe opening formed in the other end of the air conveying pipeline serves as a material outlet.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a powder material transmission system, in particular to a metering air-delivered shell powder device and an operation method thereof. Background technique [0002] Due to the light-weight materials such as rice husk and bamboo powder, according to the characteristics of such materials, the method of air conveying can be adopted. However, the existing air delivery equipment has simple functions and cannot perform functions such as weighing and measuring and automatic sieving. If it cannot be measured, it cannot be directly processed. It still needs to be weighed before it can be mixed and processed according to the appropriate ratio, and it cannot be sieved. As a result, a large amount of impurities remain in the transportation pipeline, causing pipeline pollution to further pollute the material, and it is easy to cause pipeline blockage to affect the transportation, and manual cl...

Problems solved by technology

However, the existing air delivery equipment has simple functions and cannot perform functions such as weighing and measuring and automatic sieving. If it cannot be measured, it cannot be directly processed. It still needs to be weighed before it can be mixed and processed according to the appropriate ratio, and it cannot be sieved. As a result, a large amount of impurities remain in the transportation pipeline, causing pipeline pollution to further pollute the material, and it is easy to cause pipeline blockage to affect the transportation, and manual cleaning and maintenance are required from time to time, which is a waste of labor resources

In addition, the existing air delivery equipment cannot effectively solve the problem of high-pressure air blowing up the top material, which seriously affects the feeding and transportation of powder materials
