Description

Technical Field

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

[0002] The flame retardant filter cartridge is a cylindrical element used for filtering. It is generally divided into a filter cartridge used to filter gas media. The motor drives the blades to rotate at high speed, generating negative air pressure in the sealed shell to absorb dust. Existing problems: 1. Although the traditional flame retardant filter cartridge can prevent the filter cartridge from burning during filtering, the high temperature will cause other parts of the filter cartridge to melt, affecting the filtering effect of the filter cartridge. 2. Usually, the flame retardant filter cartridge will generate high temperature during filtering. When it comes into contact with air after stopping filtering, water vapor is easily generated to enter the filter cartridge due to the large temperature difference, thus affecting the use of the filter cartridge. Utility Model Content

[0003] In view of the above, the utility model provides a flame retardant filtering device, which can not only cool the filter cartridge by spraying carbon dioxide through a compression tank when the filter cartridge temperature is too high, but also seal the pipeline through a solenoid valve when not filtering to prevent the air filter cartridge from entering and generating water vapor, thereby effectively solving the above problem.

[0005] Furthermore, the input end of the microcontroller is connected to the temperature sensor, and the output end of the microcontroller is connected to the first solenoid valve and the second solenoid valve.

[0006] Furthermore, one end of the movable bracket is arranged on the inner wall of the device shell through a hinge.

[0007] Furthermore, a power cord is provided on one side of the device housing.

[0008] The beneficial effects of the utility model are as follows: 1. When the temperature of the filter cartridge is too high, carbon dioxide can be sprayed out from the compression tank to cool the inside of the filter cartridge to prevent other parts of the filter cartridge from melting and affecting the filtering effect. 2. After the device stops, the solenoid valve seals the pipeline to prevent air from entering the filter cartridge to generate water vapor, thereby preventing water vapor from affecting the use of the filter cartridge.
