Description

Technical Field

[0001] The utility model relates to the technical field of gas filtering, in particular to a poisonous gas filtering device. Background Art

[0002] Toxic gas filter is a device specially designed to remove toxic gases from the air. It usually includes one or more filter components that can capture and remove harmful substances in the air, such as chemicals, smoke, dust, bacteria, viruses, etc. These devices are widely used in industries such as industry, medical treatment, laboratories and homes to ensure air quality and people's health.

[0003] A small amount of toxic and harmful gases will be generated during the chemical production process, which requires a gas filter device to filter. However, the filter components on some existing devices are installed integrally with the device, which is inconvenient to remove and replace. For this reason, we propose a toxic gas filter device. Utility Model Content

[0006] The filter cartridge has four groups of slots arranged at equal intervals, each of which is plugged with a group of annular plugs, each of which fits the inner wall of the filter cartridge, and each of which has a group of filter elements of different types fixedly mounted on the inner wall of the four groups of annular plugs;

[0007] A drainage mechanism is arranged on the outer surface of one side of the filter cartridge, and is used to assist in accelerating the filtration of toxic gases;

[0008] A snap mechanism is arranged on the outer surface of the filter cartridge, and the snap mechanism includes a fixed block and a clamping rod. The outer surface of the filter cartridge is fixedly installed with a number of fixed blocks equal to the annular plug plates, and four groups of fixed blocks are each provided with a group of through grooves, and a group of clamping rods are movably penetrated through each through groove on the four groups of fixed blocks, and the outer surfaces of the four groups of clamping rods are in conflict with the outer surfaces of the corresponding annular plug plates.

With the cooperation of the annular plug plate and the snap mechanism, when a certain filter element reaches the end of its service life, it can be replaced individually, which is suitable for the situation where different filter elements have different service lives, and the replacement speed is fast, thereby improving the practicability of the device.

[0010] Preferably, the drainage mechanism includes an annular cover, a fixed plate, a servo motor and a fan. An annular cover communicating with the interior is fixedly mounted on the outer surface of one side of the filter cartridge, a fixed plate is fixedly mounted on the inner wall of the annular cover, a servo motor is fixedly mounted on the side of the fixed plate away from the filter cartridge, a fan is rotatably mounted on the side of the fixed plate close to the filter cartridge, and the rotating shaft of the servo motor is drivingly connected to the fan. Under the action of the drainage mechanism on the filter cartridge, when filtering toxic gases, auxiliary gas can flow in the filter cartridge, thereby improving the filtration rate of toxic gases.

[0011] Preferably, a group of sealing gaskets are fixedly installed on the outer surfaces of both sides of the four groups of annular plug plates, and each group of sealing gaskets fits the inner wall of the slot, thereby improving the sealing effect of the device and preventing unfiltered toxic gases from escaping.

[0012] Preferably, a group of handles are fixedly mounted on the outer surfaces of the four groups of annular plug plates.

[0013] Preferably, an air inlet pipe communicating with the interior of the filter cartridge is fixedly mounted on the outer surface of the other side of the filter cartridge.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The toxic gas filtering device, through the cooperation of the annular plug plate and the snap mechanism, can be replaced individually when a certain filter element reaches the end of its service life, which is suitable for different filter elements with different service lives. The replacement speed is fast, which solves the problem that the filter assembly on some existing devices is installed as a whole with the device and is inconvenient to replace, thereby improving the practicality of the device.

[0017] (2) The toxic gas filtering device can assist the gas to flow in the filter cartridge when filtering the toxic gas through the drainage mechanism on the filter cartridge, thereby improving the filtering rate of the toxic gas. At the same time, under the action of the sealing gaskets on each annular plug plate, the sealing performance of each annular plug plate during installation can be ensured, thereby ensuring the use effect of the device and facilitating the promotion and use of the device.
