Abstract

Technical Field

[0002] Plastic products are a general term for household and industrial products made from plastic as the main raw material, including products made from injection molding, blister molding, and other processes.
[0003] Waste gas is generated during the processing of plastic products. It mainly comes from the toxic and pungent organic waste gas produced by the decomposition of plastic during melting and drawing, as well as the toxic smoke generated by the incineration of waste such as old screens and sorted plastic waste. These waste gases contain gaseous organic pollutants such as hydrocarbons and benzene series, which have a peculiar smell. When discharged into the ambient air, they will cause adverse sensory effects and cause serious harm to the human body. Therefore, waste gas needs to be treated during the processing of plastic products to reduce the harm to the environment and human body.
[0004] Exhaust gas generated during the processing of plastic products is typically filtered to remove particulate matter, dust, and soluble organic pollutants. After prolonged use, excessive amounts of particulate matter can clog the filter screen of an exhaust gas treatment device, requiring greater power to maintain adequate ventilation. This increases energy consumption, requiring frequent filter cleaning or replacement, and increasing staff workload. Therefore, an exhaust gas treatment mechanism for plastic product processing is proposed to address this issue. Utility Model Content

A sealing ring is provided between the secondary filter and the primary filter. A sealing plate is provided on the primary filter. The sealing plate is connected to the connecting air duct. A cleaning assembly for cleaning the primary filter is provided at the connection between the sealing plate and the connecting air duct.

[0023] As a preferred technical solution in this embodiment: during actual use, the staff can pass the waste gas generated by the processing of plastic products into the air inlet 11, and the waste gas will enter the filter bin 15. Then the staff can start the fan 17 to enable the waste gas in the filter bin 15 to be discharged through the exhaust pipe 19. In the process of discharging the waste gas, the waste gas can first be filtered once through the primary filter 22. The waste gas after the first filtration will be filtered twice through the secondary filter 21, and then enter the connecting air duct 18, and finally be discharged through the exhaust pipe 19. When the filtered waste gas is discharged through the connecting air duct 18, it will drive the cleaning component 3 to rotate. During the rotation of the cleaning component 3, the particulate matter attached to the primary filter 22 can be effectively cleaned.
[0024] The technical effects brought about by the above embodiments are: by providing a filter component 2, it is possible to effectively filter the particulate matter in the exhaust gas during use; by providing a cleaning component 3, it is possible to effectively achieve the effect of automatic cleaning of the filter component 2 during use, thereby avoiding the blockage of the first-level filter 22 after long-term use, which affects the filtering effect and increases the filtering energy consumption.
[0025] Example 2:
[0026] See also Figure 1-4 To further enhance cleaning effectiveness, the cleaning assembly 3 in this embodiment includes a connecting rod 31. A limit ring 32 is fixedly connected to the middle of the connecting rod 31. The limit ring 32 is provided with a mounting ring 33 for limiting position.

[0027] As a preferred technical solution in this embodiment: when the exhaust gas is discharged through the connecting air duct 18 and the exhaust duct 19 under the action of the fan 17, the airflow will drive the wind wheel 34 to rotate. During the rotation of the wind wheel 34, it can effectively drive the connecting rod 31 and the cleaning rod 35 to rotate. During the rotation of the cleaning rod 35, the surface of the primary filter 22 can be effectively cleaned, thereby effectively avoiding the effect of sweeping off the particles attached to the primary filter 22; in order to further increase the cleaning effect of the primary filter 22, the staff can control the fan 17 to draw the external air into the secondary filter 21 through the exhaust port 14 through the connecting air duct 18, and then discharge it from the air inlet 11 through the secondary filter 21 and the primary filter 22.

[0029] The working principle of the above embodiment is:
[0030] 1. During actual use, the staff can introduce the waste gas generated by the processing of plastic products from the air inlet 11, and the waste gas will enter the filter chamber 15. Then the staff can start the fan 17 to enable the waste gas in the filter chamber 15 to be discharged through the exhaust pipe 19. In the process of discharging the waste gas, the waste gas will first be filtered once through the primary filter 22. The waste gas after the primary filtration will be filtered twice through the secondary filter 21, and then enter the connecting air duct 18, and finally be discharged through the exhaust pipe 19. When the filtered waste gas is discharged through the connecting air duct 18, it will drive the cleaning component 3 to rotate. During the rotation of the cleaning component 3, the particulate matter attached to the primary filter 22 can be effectively cleaned.
[0031] 2. When the exhaust gas is discharged through the connecting duct 18 and the exhaust duct 19 under the action of the fan 17, the air flow will drive the impeller 34 to rotate. During the rotation of the impeller 34, the connecting rod 31 and the cleaning rod 35 can be effectively driven to rotate. During the rotation of the cleaning rod 35, the surface of the primary filter 22 can be effectively cleaned, thereby effectively preventing the particles attached to the primary filter 22 from being swept off. In order to further improve the cleaning effect of the primary filter 22, the staff can control the fan 17 to draw the external air into the secondary filter 21 through the exhaust port 14 through the connecting duct 18, and then discharge the exhaust gas from the air inlet 11 through the secondary filter 21 and the primary filter 22. When passing through the primary filter 22, the primary filter 22 can be effectively cleaned, and the particles attached to the primary filter 22 can be blown off.
