Description

Technical Field

[0001] This utility model belongs to the field of chemical production leakage alarm technology, specifically relating to a chemical safety production leakage alarm device. Background Technology

[0002] A gas leak alarm device is a device that can sense changes in the concentration of a specific gas and convert them into a measurable signal. It plays a key role in many fields such as chemical industry, gas industry, mining industry, and environmental protection, and is used to detect gas leaks in a timely manner to ensure personnel safety, production stability and environmental protection.

[0003] Existing gas leak alarm devices typically detect air in chemical production environments through a gas inlet at the bottom and an internal detection sensor. However, the end of this gas inlet lacks any filter structure. Since gases in industrial environments or complex locations often contain solid particles such as dust, smoke, and fibers, without the protection of a filter, these particles can directly impact the sensor's sensitive element, causing wear, scratches, or even breakage. Furthermore, when impurities in the gas clog the sensor's air intake channel or diffuser, the gas flow rate slows down, resulting in a slower response speed of the sensor to changes in gas concentration. Therefore, we propose a chemical safety production leak alarm device. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a chemical safety production leak alarm device, including a gas leak alarm device 1, a gas inlet 2 fixed at the bottom of the gas leak alarm device 1, a detection sensor 3 fixed inside the end of the gas inlet 2, a wiring terminal 4 fixed on one side of the top of the gas leak alarm device 1, a detachable suction filter mechanism provided at the end of the gas inlet 2, and a dustproof mechanism provided at the end of the wiring terminal 4. The detachable suction filter mechanism includes a filter assembly and a screw-on limiting assembly.

[0021] In this embodiment, preferably, the filter assembly includes a top cover 100 disposed at the end of the gas inlet 2 and a multi-layer filter screen 101 connected inside the top cover 100, and a sealing ring 102 disposed at the end of the top cover 100 to fit against the end of the gas inlet 2.

[0022] In this embodiment, preferably, the screw-on limiting component includes a connecting groove 200 symmetrically opened at the end of the gas inlet 2, and a connecting block 201 symmetrically fixed at the end of the top cover 100. The connecting block 201 is engaged with the connecting groove 200 to facilitate the connection between the top cover 100 and the gas inlet 2.

[0023] In this embodiment, preferably, a slot 300 is provided through the side of the connecting block 201, and a locking block 301 is fixed inside one side of the connecting slot 200. The locking block 301 is slidably connected to the slot 300 to play a locking and guiding role.

[0024] In this embodiment, preferably, a limiting groove 400 is formed on the inner side of the connecting block 201, and an inner groove 401 is formed on the inner wall of the connecting groove 200. A limiting buckle 402 is provided inside the inner groove 401. By engaging the limiting buckle 402 with the limiting groove 400, the connecting block 201 can be limited to the inside of the connecting groove 200. A telescopic spring 403 is connected between the limiting buckle 402 and the inner groove 401 to facilitate the limiting buckle 402 to reset and spring back up.

[0025] In this embodiment, preferably, the inner wall of the built-in groove 401 is symmetrically provided with sliding grooves 500, and the two sides of the limiting buckle 402 are symmetrically fixed with sliders 501. The sliders 501 are slidably connected with the sliding grooves 500, which can guide the movement of the limiting buckle 402.

[0027] The working principle and usage process of this utility model are as follows: When the top cover 100 needs to be disassembled and cleaned, first pinch the side of the top cover 100, then rotate the top cover 100 counterclockwise, causing the connecting block 201 to rotate and move inside the connecting groove 200, and pressing the limiting buckle 402. The limiting buckle 402 is compressed by external force, causing the telescopic spring 403 to deform and exit from the limiting groove 400 and retract into the inner groove 401. At the same time, the slider 501 slides inside the sliding groove 500, which plays a moving guiding role, thereby releasing the limitation on the multi-layer filter screen 101. Then, the connecting block 201 moves from the right side to the left side inside the connecting groove 200, and the slot 300 slides and separates from the slot 301. Then, the top cover 100 can be pulled down, causing the connecting block 201 to exit from the connecting groove 200, and the top cover 100 can be disassembled for cleaning. After cleaning, it can be reinstalled at the end of the gas inlet 2 to filter the air detected inside the gas inlet 2.
