Powder leaking device

Abstract

The invention discloses a powder leaking device. The device comprises a material storage chamber, a smashing chamber and a discharging chamber which are connected in sequence from top to bottom, wherein the smashing chamber comprises a driving shaft and a driven shaft, the driving shaft is horizontally arranged, the two ends of the driving shaft penetrate through the smashing chamber, a plurality of smashing discs are uniformly distributed at the part, positioned in the smashing chamber, of the driving shaft, the first smashing discs are vertical to the axis of the driving shaft; a plurality of second smashing discs are uniformly distributed on the driven shaft, and the second smashing discs and the first smashing discs are arranged in a staggered manner; a material stirring shaft is arranged at a discharging opening of the discharging chamber, and the two ends of the material stirring shaft penetrate through the discharging chamber, and one end of the material stirring shaft is connected with a second chain wheel; in the discharging chamber, the material stirring shaft is fixedly provided with a plurality of material stirring teeth vertical to the axis. The powder leaking device has a simple structure, can ensure the powder pulverization degree and the smooth powder circulation.

Description

technical field [0001] The invention relates to a process equipment, in particular to a powder leakage device used in powder spraying. Background technique [0002] In coal mine production in real life, due to the special working environment in the mine, the steel pipes installed in the mine are required to have good corrosion resistance. Zinc-rich epoxy powder coating is used for anti-corrosion. The general process is to put zinc-rich epoxy powder in the funnel, heat the steel pipe to be powdered to a certain temperature and put it on the support frame. When working, turn the steel pipe and open it. The powder outlet of the funnel moves the funnel along the guide rail, the zinc-rich epoxy powder flows out from the powder outlet of the funnel and falls on the surface of the steel pipe, that is, the spraying of the steel pipe is completed, but there are technical problems in this funnel, if the zinc-rich epoxy powder is damp When the coagulation is too large, it will block t...

[0002] In coal mine production in real life, due to the special working environment in the mine, the steel pipes installed in the mine are required to have good corrosion resistance. Zinc-rich epoxy powder coating is used for anti-corrosion. The general process is to put zinc-rich epoxy powder in the funnel, heat the steel pipe to be powdered to a certain temperature and put it on the support frame. When working, turn the steel pipe and open it. The powder outlet of the funnel moves the funnel along the guide rail, the zinc-rich epoxy powder flows out from the powder outlet of the funnel and falls on the surface of the steel pipe, that is, the spraying of the steel pipe is completed, but there are technical problems in this funnel, if the zinc-rich epoxy powder is damp When the coagulation is too large, it will block the powder outlet of the funnel, causing the interruption of the process flow. When the coagulation is small, it will flow out from the powder outlet of the funnel and fall on the surface of the steel pipe. Rolling spray particles will be formed on the surface of the steel pipe, affecting The uniformity of the sprayed surface. In addition, the rolling spray particles are easy to leak, resulting in leakage on the surface of the steel pipe and easy to be corroded. In addition, when the zinc-rich epoxy powder flows through the powder outlet of the funnel, because the shape of the funnel mouth adopts Slender type, so the powder flow is easy to flow poorly. In the prior art, an auger is generally installed at the outlet, but this method will cause uneven powder flow, which will affect the quality of the powder spray.
