Airtight detection device and working method for a canister

Abstract

The invention discloses an airtight detection device for a canister and a working method thereof. The first lifting cylinder is installed on the upper surface of the first lifting cylinder, the bottom end of the output rod of the first lifting cylinder is equipped with a connecting seat, one side of the connecting seat is fixed with a lifting plate, the upper surface of the lifting plate is installed with a second lifting cylinder, and the second lifting cylinder A clamping assembly is installed at the bottom of the output rod; the detection device clamps and fixes the canister through the fixed clamp arm and the lifting clamp arm to prevent the canister from floating up and ensure that the air tightness test of the canister can be carried out normally. The canisters of different heights are clamped and tested, which has strong applicability. The airtightness of the canister can be judged by immersing the canister in water and passing air into the canister, and observing the bubble generation. The operation Simple and low detection cost.

Description

technical field [0001] The invention relates to the technical field of detection equipment for a canister, in particular to an airtight detection device for a canister and a working method thereof. Background technique [0002] The canister is a tank device filled with activated carbon and other filling materials. The filling material has chemical and physical adsorption and filtration capabilities, which can remove dust, toxic and harmful substances in the air, and filter them through the canister. Toxic air for people to breathe; [0003] The patent document (CN109238594A) discloses an online detection device for the air tightness of a canister. The device closes the inlet and outlet of the canister and fills it with compressed air to keep the canister at a certain pressure for 1 minute, and passes the air Mass flow counts the supplementary air volume per unit time, which is the air leakage volume per unit time. This detection device can only calculate the air leakage vol...

AI Technical Summary

Problems solved by technology

[0006] The airtightness of the canister can be judged by immersing the canister in water, passing air into the canister, and observing the bubbles generated. It is easy to operate and the detection cost is low, which solves the problem. The existing gas-tight detection device for canisters cannot directly obtain the leak, which is not convenient for leak repair, complex structure, and difficult to operate.
