Abstract

The invention discloses a suction-type powder feeding system, which comprises an air power source, a gas-solid separation device, a support plate and a suction gun, and a dust removal filter element is arranged in the gas-solid separation device, which also includes a A back-flushing cleaning system for fine powder on the filter element, the back-flushing cleaning system includes a pneumatic reversing valve set between the air power source and the connecting pipeline, a feed check valve set at the gas-solid separation device, installed on the support The back blowing dust discharge one-way valve on the board and the dust removal water tank located beside the support plate and connected with the back blowing dust discharge one-way valve on the support plate; the suction gun includes the outer cylinder of the material gun and the The inner cylinder of the material gun, a cavity is formed between the outer cylinder of the material gun and the inner cylinder of the material gun, and the upper and lower ends of the outer cylinder of the material gun are respectively provided with air supply holes and feeding holes; Suction port. The suction-type powder feeding system obtained by the invention has the advantages of being convenient for sucking bagged powder and cleaning the dust-removing filter element.

Description

technical field [0001] The invention relates to the field of pneumatic conveying, in particular to a suction-type powder feeding system, which is mainly suitable for short-distance conveying of dry powder materials or granular materials. Background technique [0002] The existing feeding system is mainly composed of a suction gun, a gas-solid separation device, and an air power source connected to the gas-solid separation device. The feed tube of the device. After the air power source is started, a large pressure difference is generated between the feeding system and the outside, and then the outside air flows from the suction gun to the gas-solid separation device, generating a wind force, so that the powder at the suction gun passes through the feeding pipe It is sucked into the gas-solid separation device to realize unloading. [0003] In order to prevent the relatively fine powder from being blown from the gas-solid separation device to the air power source, there is a...
