Description

Technical Field

[0002] Chemical filters are innovative, efficient and energy-saving chemical filtration products. They are new air purification equipment mainly used to deal with odorous, toxic, harmful and corrosive gases in the air. Chemical filters are mostly used for gas filtration and purification. In airports, hospitals, office buildings and other public places, chemical filters can effectively remove odors from the air. In museums, archives, libraries and other places, chemical filters remove sulfur oxides from the air to protect collections from damage. Chemical filters are used as central controllers in chemical, petrochemical, steel and other enterprises to protect precision instruments from the hazards of corrosive gases.

[0003] At present, during the use of chemical filters, the filtration area of ​​the chemical adsorption layer inside the filter in contact with the gas is limited, and the harmful substances in the air are less adsorbed, thereby reducing the efficiency of the filter in filtering the gas. Therefore, there is an urgent need for a chemical filter that can effectively increase the contact area to solve the above-mentioned problems.

When filtering harmful gases of different concentrations, it is not convenient to add chemical adsorption layers according to needs.

After the fixed block 301 is stably engaged with the inside of the shell 1, when another fixed block 301 or the bottom of the mounting plate 203 is engaged with the top of the installed fixed block 301, the pressure rod 601 is squeezed and compressed, and the pressure rod 601 slides down to get rid of the elastic force of the compression spring 604.

[0047] Specifically, Fig. 9 and Fig.11 As shown, the rotating sleeve 401 is a cylindrical "I"-shaped structure, the outer side of the top of the rotating sleeve 401 is a pentagonal structure, and the side wall of the rotating sleeve 401 is a hexagonal structure.

By closing the cover plate 402, the cover plate 402 resists the driving rod 702, and the driving rod 702 slides away from the elastic force of the return spring 705.

The rubber pad 303 has good elasticity, so that the fixing block 301 is stably installed inside the shell 1 without loosening, so that the gas can be filtered well. The top of the pressure rod 601 is extended to the outside of the top of the fixing block 301 through the interference of the compression spring 604. The first sealing gasket 602 is in a contracted state, which is convenient for installing multiple fixing blocks 301. After the fixing block 301 is stably engaged with the inside of the shell 1, when another fixing block 301 or the bottom of the mounting plate 203 is in contact with the top of the installed fixing block 301, When the parts are engaged, the pressure rod 601 is resisted and squeezed, and the pressure rod 601 gets rid of the elastic force of the compression spring 604 and slides down. The pressure rod 601 squeezes the air storage bag 606, and the gas inside the air storage bag 606 enters the first sealing gasket 602, so that the first sealing gasket 602 expands, and the gap between the first sealing gasket 602 and the connection is tightly sealed, so that the circulating gas will not overflow, and thus better filter and purify.

The elastic force of the spring 504 slides, and the card plate 502 is separated from the toothed disc 503, so that the toothed disc 503 can rotate freely, thereby driving and controlling the rotating sleeve 401. The card plate 502 is driven and controlled by installing the push block 501, and the operation is convenient and comfortable, thereby realizing the rotation control of the rotating sleeve 401. The drive rod 702 is connected by installing the side plate 701. Under the resistance of the return spring 705, the drive rod 702 pulls the baffle plate 703 to raise the baffle plate 703 to a certain position, thereby blocking the air intake pipe 202 with the baffle plate 703, and external gas cannot enter, which plays a role of safety protection. 2 is closed, the cover plate 402 contacts the driving rod 702, the driving rod 702 slides away from the elastic force of the return spring 705, and the driving rod 702 contacts the baffle 703, causing the baffle 703 to slide down to a certain position, so that the through hole 704 on the baffle 703 is concentric with the air inlet pipe 202, so that the air inlet pipe 202 and the air inlet groove 204 are connected, and the gas can enter for filtration and purification. The installation of the top block 706 is conducive to the connection with the pressing wheel 707, which is conducive to the driving and squeezing of the pressing wheel 707 when the cover plate 402 is closed and rotated, so that the cover plate 402 can rotate and open and close smoothly, and the cover plate 402 will not cause wear between the driving rod 702.
