Problems solved by technology

[0002] Power plants take coal powder from the sampling port of the coal feeder. Open the cover of the sampling port when necessary, and then directly use the container to take it. Because the coal feeder is under positive pressure, the internal wind will blow out, causing the coal powder particles to scatter. Splashing will pollute the surrounding environment and sanitation, and it will be harmful to personal safety, and the diffusion will cause small particles of coal powder to scatter, and the sampling accuracy is not good. How to realize pollution-free and accurate sampling of raw coal, that is, coal powder, has become an urgent problem to be solved technical problem

Abstract

The invention discloses a portable raw coal sampling device. The portable raw coal sampling device comprises a sleeve, a sampling container and a connection tube which communicates the sleeve with the sampling container, wherein a strand opening is formed in each of two ends of the sleeve; the sampling container comprises a tank body, a cover body and a blockage porous plate which is arranged in the tank body; the tank body is divided by the blockage porous plate into an air inlet side and an exhaust side, an exhaust hole is formed in the cover body on the exhaust side, and a decompression filter net is arranged on the exhaust hole. The sealed sampling in the whole process is realized by utilizing the strand openings, flying ash is prevented from being splashed everywhere, the sanitation of the peripheral environment is protected, the human body is prevented from being injured, the deposition of the coal ash in the sampling container can be effectively guaranteed by combining the blockage of the blockage porous plate with the pressure-retaining exhaustion of the decompression filter net, the collection effect is improved, the completeness of the coal powder sample also can be improved, and the accuracy of the coal powder sample can be improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a portable raw coal sampling device. Background technique [0002] Power plants take coal powder from the sampling port of the coal feeder. Open the cover of the sampling port when necessary, and then directly use the container to take it. Because the coal feeder is under positive pressure, the internal wind will blow out, causing the coal powder particles to scatter. Splashing will pollute the surrounding environment and sanitation, and it will be harmful to personal safety, and the diffusion will cause small particles of coal powder to scatter, and the sampling accuracy is not good. How to realize pollution-free and accurate sampling of raw coal, that is, coal powder, has become an urgent problem to be solved technical problem. Contents of the invention [0003] The object of the present invention is to provide a portable raw coal sampling device aiming at the technical ...
