Description

Technical Field

[0001] The utility model relates to the technical field of equipment for processing and producing rubber sealing rings, in particular to a ventilation device for processing and producing rubber sealing rings. Background Art

[0002] During the production and processing of rubber sealing rings, a large amount of exhaust gas will be generated. If this exhaust gas is left unattended, it will cause considerable harm to the surrounding environment and personnel. Therefore, at present, this exhaust gas is only discharged after being filtered.

[0003] At present, the equipment used for this kind of exhaust gas filtration is generally structured as follows: filters such as HEPA filters and activated carbon filters are installed in the air duct.

[0004] It is not difficult to see that although the existing exhaust gas filtration equipment has an effective filtering effect, as the use time increases, more and more filter residues and dust will accumulate on the filter screen. In order not to reduce the filtering effect of the exhaust gas filtration equipment, the staff needs to frequently replace the filter screen. This is not only time-consuming and labor-intensive, but also leads to a high cost of exhaust gas filtration work.

[0005] Here, in order to solve the above problems, we propose a ventilation device for rubber sealing ring processing and production. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a ventilation device for the processing and production of rubber sealing rings. When in use, the ventilation device can filter the exhaust gas generated during the production and processing of the rubber sealing rings more lastingly and effectively solve the problem that "the existing exhaust gas filtering equipment is not only time-consuming and labor-intensive to use, but also leads to high costs for exhaust gas filtering work".

[0011] The filter structure includes a HEPA filter, an activated carbon filter and a photocatalyst filter; the three are stacked in sequence from bottom to top, installed and fixed in the air duct and located above the filter cartridge.

[0012] As an improvement, the filter cartridge flushing mechanism includes a filter cartridge brush mechanism and a filter screen flushing mechanism.

It is used to brush off the filter residue and dust attached to the inner wall of the filter cartridge.

[0014] As an improvement, the filter screen flushing mechanism includes a transfer tube and a nozzle; the nozzle is a cylindrical structure with a closed bottom, and the inside of the cylinder is hollow, and a plurality of water spray holes are evenly reserved on the circumferential outer wall, and a transfer tube is connected to the bottom, and the transfer tube is an L-shaped tube body structure, and the horizontal section passes through the side wall of the air duct and is fixed on the side wall;

[0015] After the nozzle is placed inside the filter cartridge, it is located between the two shaped brushes, and the rotating shaft is located inside the nozzle. It is used to flush away the filter residue and dust attached to the inner wall of the filter cartridge.

[0016] The advantages of the utility model compared with the prior art are:

[0017] 1. When this new model is in use, the filter cartridge can initially filter the exhaust gas generated during the production and processing of the rubber sealing ring, and then cooperate with the HEPA filter, activated carbon filter and photocatalyst filter to further filter the exhaust gas, with better filtering effect.

[0018] 2.

[0029] The filter cartridge flushing mechanism includes a filter cartridge brush mechanism and a filter screen flushing mechanism. Figure 3 and 4 As shown, specifically:

[0030] The filter cartridge brush mechanism comprises a motor 10, a rotating shaft 11, a fixing rod 12, a strip brush 13 and a dustproof box 15; after the motor 10 is installed and fixed on the inner side of the air duct 1, the rotating shaft 11 is fixedly connected to the output shaft, a capping plate 14 rotatably sleeved on the rotating shaft 11 is fixed on the top of the filter cartridge 2, the strip brush 13 is located on the inner side of the filter cartridge 2, and the bristles are movably connected to the inner wall of the filter cartridge 2, while the top of the brush handle is fixedly connected to the rotating shaft 11 through the fixing rod 12, after the motor 10 is installed and fixed in the dustproof box 15, the bottom wall is rotatably sleeved with the output shaft of the motor 10, and the dustproof box 15 is fixedly connected to the inner wall of the air duct 1 through a plurality of supporting rods 16;

[0031] The filter screen flushing mechanism includes a transfer tube 17 and a nozzle 18; the nozzle 18 is a cylindrical structure with a closed bottom, and the inside of the cylinder is hollow, and a plurality of water spray holes 19 are evenly reserved on the circumferential outer wall, and the bottom is connected to the transfer tube 17, the transfer tube 17 is an L-shaped tube structure, and the horizontal section passes through the side wall of the air duct 1 and is fixed on the side wall, and the transfer tube 17 is connected to the water pump through a water hose; after the nozzle 18 is placed inside the filter cartridge 2, it is located between the two L-shaped brushes 13, and the rotating shaft 11 is located inside the nozzle 18;

[0033] In the specific implementation of this embodiment: the exhaust gas generated during the production and processing of the rubber sealing ring enters the air duct 1 from the air port 5, and then passes through the filter cartridge 2, the HEPA filter screen 7, the activated carbon filter screen 8 and the photocatalyst filter screen 9 in sequence (the filter cartridge 2 is mainly used to filter large particles of dust, hair, bacteria, etc. The HEPA filter screen 7 can filter more than 99.97% of tiny particles in the air, such as pollen, dust mites, smoke, bacteria, etc. The activated carbon filter screen 8 is mainly used to absorb harmful gases in the air, such as formaldehyde, benzene, TVOC, etc. The photocatalyst filter screen 9 decomposes harmful substances in the air into harmless substances through photocatalyst materials.) and then is discharged from the air outlet 3 to enter the next step of the exhaust gas purification process;
