[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] The utility model provides Figure 1 - Figure 5 The waste gas treatment device shown is used for the preparation of a plastic granulator, comprising a collecting box 1, a waste gas bin 2 is opened on the inner wall of the collecting box 1, a sewage bin 3 is arranged on the inner wall of the collecting box 1, the waste gas bin 2 is communicated with the sewage bin 3, a connecting pipe is connected to the top of the waste gas bin 2, which is used to connect the discharge of the waste gas of the plastic granulator, and discharge the waste gas of the plastic granulator into the waste gas bin 2, and the sewage bin 3 is used to collect particulate impurities in the waste gas in the waste gas bin 2, and a discharge pipe can be arranged at the bottom of the waste gas bin 2, this discharge pipe can not only discharge the waste gas filtered by the waste gas bin 2, but also can be connected to subsequent processing equipment to ensure that the waste gas is safely discharged after further treatment.

[0023] Storage cabinets 6 are slidably arranged on both sides of the collecting box 1, and the storage cabinets 6 are slidably connected to the inner wall of the sewage discharge bin 3. A rubber sealing ring is fixedly arranged on the outer wall of the storage cabinet 6, and the rubber seal is in squeeze contact with the inner wall of the sewage discharge bin 3. The storage cabinet 6 is used to collect impurities dropped from the filter cotton 402, thereby facilitating the collection of impurities, and the sealing ring is in squeeze contact with the inner wall of the sewage discharge bin 3, thereby ensuring the sealing connection strength between the storage cabinet 6 and the sewage discharge bin 3, enhancing the sealing between the storage cabinet 6 and the sewage discharge bin 3, and preventing the leakage of exhaust gas or impurities.

[0024] The inner wall of the waste gas bin 2 is provided with a separation component for separating impurities in the waste gas, which is mainly used to effectively separate impurities in the waste gas entering the waste gas bin 2. The separation process utilizes the power generated when the waste gas is discharged, and no additional energy consumption is required to achieve filtering and separation of impurities in the waste gas.

[0025] The separation component includes a first spring 401, and the first spring 401 has a plurality of equidistant fixed arrangements on the inner wall of the waste gas bin 2. A filter cotton 402 is fixedly arranged at one end of the first spring 401. The filter cotton 402 is arranged in a cone shape, and both sides of the filter cotton 402 face the inner wall of the sewage bin 3. The conical structure makes the surface area of ​​the filter cotton 402 larger, thereby increasing the contact area with the exhaust gas, which is conducive to more efficiently capturing particulate impurities in the exhaust gas. Secondly, both sides of the filter cotton 402 face the inner wall of the sewage bin 3, ensuring that the captured particulate impurities can directly slide into the sewage bin 3.

[0026] A plurality of filter holes 403 are evenly spaced on the filter plate cotton, and a filter device 404 is placed on the inner wall of the waste gas bin 2. The filter device 404 includes an air filter, a gas filter and a HEPA filter, which are prior arts and will not be described in detail here.

[0027] During operation, when the exhaust gas continues to enter the exhaust gas bin 2, it will directly contact the filter cotton 402. The impurities in the exhaust gas will gradually accumulate on the filter cotton 402 under the action of gravity, causing the filter cotton 402 to be subjected to downward pressure. This pressure causes the filter cotton 402 to start to slide downward, while compressing the first spring 401 below. As the filter cotton 402 slides down, the first spring 401 will gradually be compressed. Through the compression and resetting of the first spring 401, the impurities attached to the surface of the filter cotton 402 slide down along the two sides of the filter cotton 402 under the action of the sliding force, and finally flow smoothly into the sewage bin 3, thereby achieving effective removal of impurities and realizing the self-cleaning function of the filter cotton 402, reducing the frequency of manual cleaning, and improving the continuity and efficiency of exhaust gas treatment.

[0028] Considering that impurities in the exhaust gas may clog the filter holes 403 on the filter cotton 402, a dredging component for dredging the filter cotton 402 is arranged on the inner wall of the sewage discharge bin 3, and the dredging component includes a slide groove 501, and a second spring 502 is fixedly arranged on the inner wall of the slide groove 501. A slide rod 503 is fixedly arranged at one end of the second spring 502, and a flexible sheet 504 is fixedly arranged at one end of the slide rod 503 close to the filter cotton 402. This flexible sheet 504 is made of elastic and flexible material to reduce the damage to the filter cotton 402 during the dredging process. Damage: As the filter cotton 402 slides up and down, the sliding rod 503 and the flexible sheet 504 in contact with it will vibrate synchronously. This vibration effectively shakes off the impurities blocked in the filter hole 403, thereby unblocking the filter hole 403 blocked by impurities, ensuring the stability of the filtering effect, and reducing the damage to the filter cotton 402 by reducing the direct impact on the filter cotton 402, thereby significantly extending the service life of the filter cotton 402. The whole process has a high degree of automation, does not require frequent manual intervention, and improves the continuity and efficiency of exhaust gas treatment.

[0029] During operation, as the exhaust gas is continuously input into the exhaust gas bin 2, when more impurities accumulate on the filter cotton 402, resulting in an increase in weight, the filter cotton 402 will press the first spring 401 downward under the action of gravity, and through the reset of the first spring 401, it will then start a reciprocating sliding movement up and down. During this process, the filter cotton 402 will contact the flexible sheet 504. When the flexible sheet 504 contacts the filter cotton 402, it will squeeze the second spring 502 through the slide rod 503. The second spring 502 will be compressed after being squeezed, and then release energy to reset. This compression and reset process will produce knocking vibration on the filter cotton 402. This knocking vibration can effectively knock out the impurities blocked in the filter hole 403 from the filter hole 403, thereby achieving the purpose of automatic dredging. This method not only improves the filtration efficiency and reduces the blockage of the filter hole 403 by impurities, but also extends the service life of the filter cotton 402 and reduces maintenance costs.
