Solid particulate matter collection device

Abstract

The invention discloses a solid particulate matter collection device comprising a first part 1, a second part 2 and a fastening part 3, wherein the first part 1 and the second part 2 are parts with penetrating insides along an axial direction; the fastening part 3 is a hollow part with both ends opened and is sleeved at the outer sides of the first part 1 and the second part 2; an annular fixed frame 32 of the fastening part 3 contacts with the edge 21 of the second part 2; screw threads positioned at the inner side of the fastening part 3 are meshed and screwed with screw threads positioned at the outer side of the first part 1; and the first part 1 is connected with the second part 2. Because the parts are locked and connected through the screw threads, the first part 1 and the second part 2 can be locked or loosened by only rotating the fastening part 3 without needing tools, i.e. a spanner and the like, when a device is disassembled, therefore filter papers can be very conveniently taken out and replaced.

Description

technical field [0001] The invention relates to the analysis field of fluids such as gas or liquid, and more specifically relates to a solid particle collection device. Background technique [0002] During the analysis of fluids such as gases or liquids, it is necessary to conduct quantitative analysis of solid particles such as smoke and impurities. The process of quantitative analysis includes that when the fluid flows through the quantitative volume, the control valve cuts off the passage, takes out the filter paper set in the fluid passage, and measures the residual solid particles on the filter paper. The entire control process ensures that the gas path or liquid path is sealed, and no leakage is allowed. This requires that the filter paper be fixed and the effective part of the filter paper be sealed in the gas path.

Problems solved by technology

However, when performing quantitative analysis, the experimenter usually needs to obtain experimental data multiple times according to the standard, which requires the installation of filter paper, measurement process, acquisition of filter paper, and installation of new filter paper in a short period of time, repeated many times

In the prior art, the components of this flange type scheme need to use a wrench tool to complete the installation and disassembly of bolts or screws, and the number of bolts or screws on the flange is large, so when replacing the filter paper during the experiment, installation and disassembly are very difficult. Complicated, affecting experimental efficiency
