Powder extraction device

Abstract

The invention discloses a powder extracting device. The powder extracting device comprises a powder separation pipeline and a cyclone separator. The powder separation pipeline is connected to a feeding pipeline of processing equipment; a suction fan is connected inside the powder separation pipeline; the other end of the powder separation pipeline is connected with the cyclone separator; a powder extraction pipe is connected with an outer shell of the cyclone separator along the tangent line; a branch pipe connector is connected with the outlet end of the powder extraction pipe; the branch pipe connector is connected with two or more discharging pipes; and valves are connected to the discharging pipes. The powder separation pipeline is connected to the pipeline of the processing equipment, and the cyclone separator is further disposed on the powder separation pipeline; due to the facts that the cyclone separator generates outward high air pressure, external air is quite difficult to enter the pipelines, and the cyclone separator further achieves uniformly mixing function, so that the quality of an extracted sample has better representativeness of sampling; and the valves are connected to the discharging pipes so that periodic sampling can be performed as required, and normal processing is not affected.

Description

technical field [0001] The invention relates to a sample sampling device, in particular to a powder sampling device. Background technique [0002] In the process of powder coating production, since the powder is mostly processed in a closed environment, it is usually necessary to take samples and open an opening on the pipeline in the production process to directly extract, but directly extracting, the inside of the pipeline will be directly connected to the outside. Connectivity, external dust and other substances will enter and exit the pipeline during processing, affecting the quality of the product. Contents of the invention [0003] To address the deficiencies in the prior art, a sorting device that does not allow external impurities to enter is needed. [0004] According to the above technical solution, the present invention requires a powder extraction device, including a material distribution pipeline and a cyclone separator, the material distribution pipeline is ...
