[0004] However, in the prior art, the production device will be wetted by the spray nozzle during use, resulting in problems in the plastic processing process. Therefore, a plastic processing waste gas extraction and exhaust device is needed now. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a plastic processing waste gas extraction and exhaust device, which can start to treat the waste gas by passing water inside the water tank, and share the pressure of the air box through each group of air extraction pumps, so as to solve the technical problems mentioned in the background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A plastic processing waste gas extraction and exhaust device, including a gas collection box and a mounting plate. A flow dividing block is installed inside the gas collection box. A water tank is clamped and installed on the upper part of the gas collection box.

[0012] Preferably, two air extraction pumps are symmetrically installed on the upper surface of each air extraction box, the air extraction pumps are connected and installed with the exhaust pipes, and the output end of the exhaust pipe is located below the abutting blocks inside the water tank.
[0013] Preferably, the mounting plate is in snap connection with the top of the air collecting box, the air box is installed in the middle of the mounting plate, a connecting pipe is connected and installed at the bottom end of the air supply pipe, and the connecting pipe is inserted and installed with the air box.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. The waste gas is gathered through the air collecting box, and the waste gas is split by the flow splitting block inside the air collecting box to the positions of two groups of air extraction boxes. The waste gas is extracted by the air extraction pumps and sent into the water tank through the exhaust pipes. Since there is water inside the water tank and the output end of the exhaust pipe is located inside the water, the introduced waste gas can be directly adsorbed by the water, completing the treatment of the waste gas. Moreover, the filter plate inside the water tank can adsorb impurities in the waste gas, enabling the waste gas to be discharged more safely.
[0016] 2. The air extraction pumps are used to share the pressure of the air box. The air extraction pumps send the waste gas into the water tank, and the air box only needs to extract the waste gas inside the water tank, avoiding the air box directly working to extract the waste gas inside the air collecting box and reducing the difficulty of waste gas treatment.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] The present utility model provides: A plastic processing waste gas extraction and exhaust device, as Figures 1 - 6 shown, includes an air collecting box 1 and a mounting plate 13. A shunt block 3 is installed inside the air collecting box 1. A water tank 4 is clamped and installed on the upper part of the air collecting box 1. A group of air extraction boxes 8 are respectively installed on both sides of the water tank 4. The top end of the air extraction box 8 is connected and installed with an exhaust pipe 9, and the output end of the exhaust pipe 9 extends out of the inside of the water tank 4; The top end of the water tank 4 is movably clamped and installed with an air box 14, and the output end of the air box 14 is hermetically inserted and installed with an air supply pipe 15.
[0026] Preferably, the bottom of the shunt block 3 is triangular, and the left and right sides of the shunt block 3 do not fit the inner wall of the air collecting box 1. A connecting shell 2 is installed at the top end of the air collecting box 1. The connecting shell 2 installed at the top end of the air collecting box 1 and the shunt block 3 inside the air collecting box 1 limit the water tank 4, so that the water tank 4 can be stably installed and ensure the connection between the water tank 4 and the air collecting box 1. The triangular bottom of the shunt block 3 can cooperate with the air collecting box 1 to shunt the waste gas, so that the gas can be extracted through the air extraction box 8.
[0027] Furthermore, the water tank 4 is arranged to fit the upper surface of the shunt block 3. The two air extraction boxes 8 are inserted into the spaces on both sides of the shunt block 3 and the air collecting box 1. When the two air extraction boxes 8 are inserted into the spaces on both sides of the shunt block 3 and the air collecting box 1, it can ensure that the gas will not escape, so that the gas can be stably extracted by the air extraction pump 10 and sent into the water tank 4 through the exhaust pipe 9 to complete the treatment of the waste gas.
[0028] Furthermore, two groups of slots 5 are symmetrically arranged on the left and right sides of the water tank 4. A water pipe 6 is installed through the front side of the water tank 4. A set of abutting blocks 7 are respectively installed at the four inflection points inside the water tank 4. The slots 5 arranged on the left and right sides of the water tank 4 enable the exhaust pipe 9 to extend into the water tank 4. The water pipe 6 installed through the front side of the water tank 4 enables the water inside the water tank 4 to circulate stably, so that the sediment and the waste gas impurities in the water can be sent out. The installed abutting blocks 7 are used to limit the filter plate 11.
[0029] It should be noted that a filter plate 11 is placed inside the water tank 4. Limiting grooves 12 are symmetrically arranged on both sides of the filter plate 11 corresponding to the position of the exhaust pipe 9. The filter plate 11 is placed in contact with the surfaces of each group of abutting blocks 7. The installed filter plate 11 can adsorb the floating impurities when the air box 14 pumps air.
[0030] Specifically, two groups of air extraction pumps 10 are symmetrically installed on the upper surface of each air extraction box 8. The air extraction pumps 10 are connected and installed with the exhaust pipe 9. The output end of the exhaust pipe 9 is located below the abutting blocks 7 inside the water tank 4. The two groups of air extraction pumps 10 arranged on the upper part of the air extraction box 8 enable the gas inside the gas collection box 1 to be quickly sent into the water tank 4 to complete the first-step adsorption through the water inside the water tank 4. At the same time, the pressure of the air box 14 is reduced by the two groups of air extraction pumps 10, changing the one-time air extraction into segmented air extraction, and reducing the pressure of the device during use.
[0031] In addition, the mounting plate 13 is clamped in contact with the top end of the gas collection box 1. The air box 14 is installed in the middle of the mounting plate 13. A connecting pipe 16 is connected and installed at the bottom end of the air supply pipe 15. The connecting pipe 16 is inserted and installed with the air box 14. The mounting plate 13 limits the air box 14, enabling the air box 14 to be removed and repaired. The connecting pipe 16 at the bottom of the air supply pipe 15 is butted against the output end of the air box 14, enabling the waste gas to be quickly discharged.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
