Tester for intensity of Civil Air Defence dedicated impregnated activated carbon and test method thereof

Abstract

The invention relates to an intensity tester and discloses a tester and a test method for intensity of Civil Air Defence dedicated impregnated activated carbon. The tester comprises a frame (1) and a motor (2), wherein two driving pulleys (3) are arranged on the motor (2), and a damping block (4) is arranged between the motor (2) and the driving pulleys (3); two sets of support mechanisms (5) are fixed on the top of the frame (1), and the heights from the two sets of support mechanisms (5) to the top of the frame (1) are equal; a roller (6) is arranged at the middle part of the two sets of support mechanisms (5), antiskid layers (7) are arranged on parts, contacted with transmission, of two ends of the roller (6), and a stop block (8) is arranged on the inner wall of the middle part of the roller (6). The test method comprises main steps of drying, first screening, first weighing, sample abrasion, second screening, second weighing and calculation. The invention has the advantages that equipment is simple and convenient to use, the floor space is small, and high precision measurement of activated carbon intensity can be realized via the test steps.

Description

technical field [0001] The invention relates to a strength tester, in particular to a strength tester for impregnated activated carbon special for civil air defense and a test method thereof. Background technique [0002] Activated carbon is a kind of black porous solid carbon, which was produced by carbonization and activation of wood, hard nut shells or animal bones in the early stage, and later changed to coal through crushing, molding or carbonization and activation of uniform coal particles. The main functions are: used in gas masks to filter gas, used in industry to decolorize and purify the solution, and used in medicine to absorb toxins, bacteria or gases in the gastrointestinal tract. [0003] Strength is an important physical performance test index of activated carbon. The existing activated carbon test method is: put the activated carbon sample in a professional pan with a certain number of stainless steel balls, and perform a combined movement of rotation and hit...

AI Technical Summary

Problems solved by technology

[0004] Using the above method, due to the irregular movement of the steel ball, it is easy to prevent a part of the activated carbon from being hit, and the strength detector on the market is easy to damage the activated carbon due to the vibration of the machine itself, resulting in inaccurate measurement of the strength of the activated carbon; in addition, the existing The structure of the strength detector is relatively complex, it occupies a large area, and it is inconvenient to operate
