Problems solved by technology
[0006] Aiming at the deficiencies of the prior art, the present invention provides a device for testing the overall dustproof performance of the canister, which overcomes the deficiencies of the prior art, and has a reasonable design and a compact structure. The airflow is input by imitating the characteristics of human breathing, and the air volume is replenished per unit time through air mass flow statistics. Finally, the dustproof performance of the canister can be measured by comparing the filter paper with the standard range color guide, which is effective It solves the problem of simple dustproof performance test structure and unsatisfactory test results

The invention provides an overall dustproof performance test device for a canister. The device comprises a test box and two box doors hinged at the front side wall of the test box by hinges, wherein the inner top wall of the test box is fixedly connected with a hydraulic cylinder, the output end of the hydraulic cylinder is connected with a fixing device, the fixing device is in through connectionto the output end of a simulated breathing device through a connecting hose, and the simulated breathing device is fixedly inserted on the top wall of the test box. The invention overcomes the deficiencies of the prior art, has reasonable design and compact structure, and can measure the dustproof performance of the canister by firstly closing the inlet and outlet of the canister, then inputtingthe airflow for simulating the characteristics of human breath, counting the supplemented air flow in a unit time by air mass flow, and finally comparing with the standard range colorimetric plate bythe filter paper, thereby effectively solving the problem that the dustproof performance test is simple in structure and the test result is not ideal.
Description
technical field [0001] The invention relates to the technical field of fire testing equipment, in particular to a device for testing the overall dustproof performance of a canister. Background technique [0002] The canister is a device that removes dust and toxic and harmful substances in the air through physical adsorption and chemical reaction for human breathing. Usually canisters are used in conjunction with gas masks. Canisters are very important epidemic prevention and protective articles in social life, especially when catastrophes such as earthquakes, floods, and infectious diseases (such as SARS) are prevalent, it is very important. [0003] Since the canister is usually used in conjunction with the gas mask, the quality of the canister mainly depends on its filtering and adsorption functions, which requires that the dustproof performance of the canister must be kept good, so the dustproof performance of the canister Detection is even more important. [0004] Th...
