The problem of laboratory air treatment is an important issue that urgently needs to be solved.

[0003] After searching, Chinese patent CN212790471U was found and announced a laboratory air filter. Through the first filtering device, part of the harmful gas is adsorbed by the activated carbon plate, and the carbon powder and dust are adsorbed by the charge plate, which can effectively treat the harmful gas. The device can react the harmful gas with the pre-placed solvent or dissolve it in the solvent through the second filtering device, and can perform different treatments for different gases. The placement and discharge of the solvent are relatively convenient. The air inlet pipe and the discharge pipe are both rotatable pipes, which are convenient for adjusting the exhaust position and convenient for draining. The activated carbon plate and the charge plate are relatively convenient to use and clean, and can be replaced or cleaned in time as needed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2 A filter for a clean laboratory comprises a shell 1, a filter plate 2 is installed on the side wall of the shell 1, the filter plate 2 is passed through with mounting screws threadedly connected to the shell 1 for assembling and disassembling the filter plate 2, the filter plate 2 is provided with filter holes 3 for intercepting foreign particles, and a fixing rod 4 is fixedly installed between the front side wall and the opposite side of the rear side wall of the shell 1, and the number of the fixing rods 4 is three.

[0020] Among them, a servo motor 5 is fixedly installed on the front wall of the shell 1, and a threaded rod 6 is fixedly installed on the output shaft of the servo motor 5. When the servo motor 5 is started, the threaded rod 6 rotates to gradually remove the accumulated impurity particles. The threaded rod 6 is rotatably connected to the shell 1 and can support the threaded rod 6. The outer surface of the fixed rod 4 is slidably connected with a movable seat 7, and the movable seat 7 can slide laterally on the outer surface of the fixed rod 4. There are two movable seats 7, one of which is threadedly connected to the outer surface of the threaded rod 6. The rotation of the threaded rod 6 can drive the movable seat 7 to move laterally. A dirt box 9 in contact with the side wall of the filter plate 2 is placed on the shell 1 to catch the impurity particles. The upper surface of the dirt box 9 is an inclined surface, so that the impurities in the filter hole 3 can slide smoothly into the dirt box 9 and be collected.

[0021] In addition, a socket is provided on the top wall of the shell 1, into which an activated carbon plate 10 connected to the inner wall of the shell 1 is inserted, which is used to remove gas odors in the laboratory. A mounting plate 11 is fixedly installed on the top of the activated carbon plate 10, and connecting screws threadedly connected to the top wall of the shell 1 are passed through the mounting plate 11 for disassembling and assembling the activated carbon plate 10.

[0022] In addition, a pipe 12 connected to the inner cavity of the shell 1 is fixedly installed on the rear wall of the shell 1, and a fan 13 is fixedly installed on the pipe 12. The air inlet and air outlet of the fan 13 are both connected to the pipe 12. The air inlet of the fan 13 is the left side of the fan 13, and the air outlet of the fan 13 is the right side of the fan 13. After the fan 13 is started, it can absorb and process the air impurities in the laboratory.

[0023] See also Figure 2-3 An extrusion assembly 8 for removing impurities in the filter hole 3 is provided on the shell 1, the filter hole 3 and the movable seat 7. The extrusion assembly 8 includes a movable shaft 81, a movable roller 82, a removal block 83, a gear 84 and a rack 85. The movable shaft 81 is rotatably connected to the movable seat 7. The movable shaft 81 is rotatably connected to the two movable seats 7. The movable roller 82 is fixedly connected to the outer surface of the movable shaft 81 and can rotate with the movable shaft 81. One of the fixed rods 4 is located above the movable roller 82, and the other two fixed rods 4 are located below the movable roller 82.

[0024] In addition, the rejecting block 83 is fixedly connected to the outer surface of the movable roller 82 and can rotate with the movable roller 82. The rejecting block 83 is plugged into the filter hole 3. After the rejecting block 83 is inserted into the filter hole 3, the foreign particles blocked in the filter hole 3 can be squeezed out to avoid blockage. The filter hole 3 and the rejecting block 83 are both truncated cone-shaped, so that the filter hole 3 and the rejecting block 83 are compatible. The gear 84 is fixedly installed at the upper and lower ends of the movable shaft 81 and can rotate with the movable shaft 81. The rack 85 is fixedly installed on the inner wall of the shell 1. The gear 84 is meshed with the rack 85. Under the meshing transmission of the gear 84 and the rack 85, the movable seat 7 drives the movable shaft 81, the movable roller 82 and the rejecting block 83 to move and rotate at the same time, thereby removing the foreign particles blocked in each filter hole 3 and ensuring the filtering effect of the filter hole 3.

[0025] When the present embodiment is in use, the fan 13 is started, the pipe 12 draws air, and the air impurities in the laboratory are sucked from the filter holes 3. The impurities hit the filter holes 3 and are intercepted inside, while the air passes through the filter holes 3. At the same time, the servo motor 5 is started, the threaded rod 6 rotates, the movable seat 7 moves, and the movable shaft 81, the movable roller 82, the rejection block 83 and the gear 84 are pulled to move along. Under the meshing transmission of the gear 84 and the rack 85, the movable shaft 81, the movable roller 82 and the rejection block 83 rotate while moving, so that the rejection block 83 squeezes out the impurity particles blocked in the filter holes 3 and drops them into the dirt box 9 for collection. The harmful gas that passes through the filter holes 3 is adsorbed by the activated carbon plate 10 and discharged from the air outlet end of the pipe 12.

[0026] The beneficial effects of the above embodiments are:

[0027] The filter of the clean laboratory is provided with an extrusion assembly 8. After use, the extrusion assembly 8 drives the movable shaft 81, the movable roller 82 and the rejection block 83 to rotate while moving under the push of the movable seat 7 and the meshing transmission of the gear 84 and the rack 85, so that the rejection block 83 can be inserted into the filter hole 3 on the filter plate 2, and then the foreign particles in the filter hole 3 are pushed out, thereby avoiding the filter hole 3 from being blocked and ensuring the normal filtering effect of the filter hole 3.
