Novel powder feeding machine capable of being used by connecting negative pressure pump

Abstract

The invention discloses a novel powder feeding machine capable of being used by connecting a negative pressure pump. According to the key points of the structure, the novel powder feeding machine is composed of a control part, a filter barrel, a discharging door section and a bottom section which are sequentially connected through clamps from top to bottom, the control part comprises a pulse back-flushing valve and a vacuum reversing valve communicating with the negative pressure pump, the pulse back-flushing valve is connected with a filter pressure-reducing valve through a back-flushing gasbag, and the filter pressure-reducing valve is connected with an electromagnetic valve for controlling a working state of the filter pressure-reducing valve. The novel powder feeding machine has the beneficial effects that non-manual contact of materials can be achieved, powder is conveyed in an airtight mode, thus the overflow situation is avoided, manual labor is reduced while energy conservation and environmental protection are achieved, labor force is reduced, each part is connected through the corresponding clamp, the barrel design is adopted, disassembling is convenient, and cleaning ismore convenient.

Description

technical field [0001] The invention belongs to the technical field of feeding equipment, and specifically relates to a novel powder feeding machine that can be used by connecting a negative pressure pump. Background technique [0002] At present, most of the powder feeders in the market use spiral conveying, but in the process of spiral conveying, powder overflow is prone to occur, which not only causes waste of materials, but also pollutes the working environment. At the same time, the work intensity of workers is also increased, so there is an urgent need for a powder feeding machine that can convey powder materials in a sealed manner, energy saving and environmental protection. Contents of the invention [0003] The purpose of the present invention is to provide a novel powder feeding machine that can be used by connecting a negative pressure pump and can avoid powder overflow through airtight conveying. [0004] In order to achieve the above purpose, the technical so...
