[0002] With the acceleration of industrialization, the demand for air purification devices is growing. As an important air purification device, the mobile activated carbon adsorption device is widely used in various indoor air purification scenarios due to its high efficiency in adsorbing harmful gases and particulate matter.

Secondly, the entire process of replacing the filter element needs to be carried out manually, which is cumbersome and requires shutdown operation, which also significantly increases the labor cost and the overall work efficiency is low.

[0037] See also Figure 1-6As shown, the utility model provides a technical solution of a mobile activated carbon adsorption device with a self-cleaning function: a mobile activated carbon adsorption device with a self-cleaning function, comprising a cart 1, a mounting cylinder 2 is mounted on the bottom plate of the cart 1, an activated carbon filter disc 3 is movably mounted inside the mounting cylinder 2, a circulation assembly 4 for circulating gas is mounted on one side of the mounting cylinder 2, a self-cleaning mechanism 5 is mounted on the side of the mounting cylinder 2 away from the circulation assembly 4, a mounting plate 6 is fixedly mounted on the inner wall of the mounting cylinder 2 above the activated carbon filter disc 3, a sealing assembly 7 is mounted on the mounting plate 6 and the activated carbon filter disc 3, and a driving mechanism 8 for driving the activated carbon filter disc 3 is also mounted on the lower end of the mounting cylinder 2. The self-cleaning mechanism 5 includes a lifting motor 501, a partition 504, a one-way valve 506 and a sewage pipe 507, and the lifting motor 501 is fixed to the side of the cylinder wall of the mounting cylinder 2 away from the circulation assembly 4 through a bracket. The output end of the lifting motor 501 is connected with a screw rod 502, and a lifting sleeve 503 is threadedly connected to the screw rod 502. The partition 504 is fixedly installed on the upper end surface of the mounting plate 6. The lower end of the lifting sleeve 503 is connected with a piston disc 505. The piston disc 505 is slidably sealed with the inner wall of the partition 504 and the mounting cylinder 2. A one-way valve 506 is installed through the lower end of the partition 504. The one-way valve 506 is used to introduce the clean air in the circulation component 4 to the bottom of the piston disc 505 and prevent the air from flowing back when the piston disc 505 is pressed down. The sewage pipe 507 is installed on the horizontal plate at the lower end of the mounting cylinder 2. The air inlet of the sewage pipe 507 is located below the piston disc 505 and fits the lower end surface of the activated carbon filter disc 3. The other end of the sewage pipe 507 is arranged outside the mounting cylinder 2 for connecting a storage device or connecting to the outdoors through other pipelines. When the device is working normally, the air to be filtered enters through the circulation component 4, passes through the activated carbon filter disc 3, and is discharged upward. When the portion of the activated carbon filter disc 3 between the circulation components 4 needs to be cleaned, first close the sealing component 7, and then start the driving mechanism 8. The driving mechanism 8 drives the activated carbon filter disc 3 to rotate 180 degrees. At this time, the clean side of the activated carbon filter disc 3 is rotated into the circulation component 4, and the portion to be cleaned is rotated between the piston disc 505 and the drain pipe 507. At this time, the sealing component 7 can be started for cleaning. The lifting motor 501 is controlled by an external control system and started. The lifting motor 501 drives the screw rod 502 to rotate, thereby driving the lifting sleeve 503 and the piston disc 505 to rise to the highest point. During this process, the clean air in the circulation component 4 is introduced into the bottom of the piston disc 505 through the one-way valve 506. Then, the lifting motor 501 is reversed by the external control system, and the piston disc 505 descends to pressurize the air below, forcing the air to pass through the activated carbon filter disc 3 and blow downward, and bring out the impurities attached to the activated carbon filter disc 3, and finally discharge them through the drain pipe 507. The piston disc 505 can be driven by the lifting motor 501 to perform multiple rapid lifting operations to optimize the cleaning effect of the activated carbon filter disc 3.Later, the filter can be continued by rotating the driving mechanism 8 into the circulation component 4. The self-cleaning mechanism 5 realizes the self-cleaning effect of the contaminated activated carbon filter element, which saves maintenance costs compared with directly replacing the activated carbon filter element, and eliminates the tedious manual disassembly and installation operations. Self-cleaning can be performed without stopping the machine, which effectively improves the working efficiency of the adsorption device and reduces labor costs.

[0038] The sealing assembly 7 includes a partition bar 701 and an electromagnet 704. The partition bar 701 is installed on the activated carbon filter disc 3 through the center. A sealing strip 702 is slidably connected in the groove at the upper end of the partition bar 701. The sealing strip 702 can move up and down in the groove. A permanent magnet 703 is installed inside the sealing strip 702. The electromagnet 704 is installed inside the mounting plate 6 and matches the permanent magnet 703. During the operation of the device, when the activated carbon filter disc 3 is in a stationary state, the electromagnet 704 is energized to generate an attraction to the permanent magnet 703, thereby driving the sealing strip 702 to rise and fit the lower end surface of the mounting plate 6 to achieve a sealing effect. When the activated carbon filter disc 3 needs to be moved, the electromagnet 704 is powered off, and the sealing strip 702 falls back into the partition bar 701 under the action of gravity. At this time, the activated carbon filter disc 3 can be rotated. The sealing assembly 7 not only ensures the flexible rotation of the activated carbon filter disc 3, but also ensures the sealing between the activated carbon filter disc 3 and the mounting plate 6 during self-cleaning, so that the self-cleaning effect is further improved.

[0039] The circulation component 4 includes a fan 401 and an air outlet pipe 403. The fan 401 is installed on one side of the upper end surface of the bottom plate of the cart 1 through a bracket. The output end of the fan 401 is connected to the air inlet pipe 402. The exhaust port of the air inlet pipe 402 passes through the side of the installation tube 2 away from the sewage pipe 507 and fits the lower end surface of the activated carbon filter plate 3. The lower end of the air outlet pipe 403 is connected to the air hole on one side of the installation plate 6, and the upper end of the air outlet pipe 403 is connected to the exhaust hole at the upper end of the installation tube 2. When the circulation component 4 starts working, the external air is introduced into the air inlet pipe 402 through the fan 401, and then filtered through the activated carbon filter plate 3 and discharged upward through the air outlet pipe 403.

[0040] The driving mechanism 8 includes a driving motor 801, which is mounted on the bottom of the mounting cylinder 2 through a bracket, and the output end of the driving motor 801 is connected to a transmission shaft 802, and the upper end of the transmission shaft 802 is connected to the lower end of the activated carbon filter disc 3. When the activated carbon filter disc 3 needs to be rotated, the driving motor 801 is started by an external control system, and the driving motor 801 can drive the activated carbon filter disc 3 to rotate through the transmission shaft 802.

[0041] The upper end of the installation cylinder 2 is provided with ventilation holes 9 on both sides of the lifting motor 501. When the piston plate 505 moves, the ventilation holes 9 can ensure the air pressure balance inside the installation cylinder 2.

[0042] A protective net 10 is installed in the exhaust hole at the upper end of the installation tube 2 , and the protective net 10 can prevent external debris from falling into the installation tube 2 .

[0043] Sealing bristles 11 are installed on the upper ends of the air inlet pipe 402 and the sewage pipe 507 and the lower end surface of the mounting plate 6. When the activated carbon filter disc 3 rotates, the sealing bristles 11 can block the gaps above and below the activated carbon filter disc 3 to increase the sealing effect.
