Abstract

The invention discloses a sand and dust test box calibration device. The device comprises samplers and an air extractor, wherein the air extractor comprises a cubic shell; a tubular busbar is penetrated in the shell; two ends of the busbar are sealed; a tubular exhaust tube is penetrated on one side of the shell; at least 9 tubular conduits are penetrated on the other side of the shell; both the exhaust tube and the conduits are communicated with the inner cavity of the busbar; and the end, extending to the outer part of the shell, of each conduit is spirally screwed with a sampler.

Description

Technical field [0001] The invention relates to the technical field of sand and dust test equipment, in particular to a sand and dust test box calibration device. Background technique [0002] The sand and dust test equipment calibration specification puts forward the requirements for the calibration of sand and dust concentration. The sampler is used to collect sand and dust through multiple measurement points. However, the actual sand and dust test equipment has only one exhaust hole leading into the box, and multiple measurement points cannot be arranged at the same time. , Which brings difficulties to the collection of sand and dust concentration. It is necessary to arrange the collection one by one when collecting, which greatly increases the test time and restricts the calibration process. Summary of the invention [0003] The purpose of the present invention is to provide a sand and dust test box calibration device to solve the problem that the existing sand and dust test e...
