External pressure type dry powder pump

Abstract

The present invention provides an external-compression dry powder pump for compression transportation of dry powder material and comprises a blade-typed rotor and a pump body shell. The pump body shell is provided with a dry powder material inlet and a dry powder material outlet and is characterized in that the pump body shell is also provided with a plurality of interfaces, and a plurality of interfaces are communicated correspondingly with a plurality of interval spaces separated by adjacent blades of the rotor in the pump body shell.

Description

technical field [0001] The invention relates to a device capable of pressurizing and transporting dry powdery substances, in particular to an external pressure dry powder pump. Background technique [0002] The existing liquid pump can pressurize the liquid, and the work required for the pressurization comes from, and only comes from, the driving machine of the liquid pump. For example: the centrifugal pump relies on the driving machine to drive the impeller to make the liquid move at a high speed, and the kinetic energy of the high-speed moving liquid is converted into potential energy when passing through the gradually expanding channel of the pump casing. The reciprocating pump relies on the driving machine to drive the piston to move with variable volume. Under the action of the one-way valve, the liquid enters from the suction port at low pressure and is sent out from the discharge port at high pressure. So far, dry powder pumps have not been successfully used in indus...

AI Technical Summary

Problems solved by technology

So far, dry powder pumps have not been successfully used in industrial production. The main reason is that dry powder is different from liquid and does not have good fluidity for liquid materials. It is easy to get stuck during movement. Conventional methods cannot use pumps to pressurize dry powder materials.
