The presence of microorganisms can cause off-odors, discoloration, and a decline in physical properties, affecting the appearance and performance of the product. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-5 As shown: A sterilization mechanism for a polypropylene processing equipment includes a conveying pipe 1. A sterilization component is provided at one end of the conveying pipe 1. The sterilization component includes a sterilization chamber 2, an ozone generator 4, and a mixing tank 5. One end of the sterilization chamber 2 is fixedly connected to the conveying pipe 1. A fixing sleeve 16 is fixedly connected to the outer ring surface of the sterilization chamber 2. An ultraviolet lamp tube 21 is embedded in one side of the inner wall of the fixing sleeve 16. The other end of the sterilization chamber 2 is fixedly connected to a connecting pipe 18. One end of the connecting pipe 18 is fixedly connected to the mixing tank 5. A reinforcing plate 20 is bolted to the top of the mixing tank 5. A support plate 8 is fixedly connected to the outer ring surface of the mixing tank 5. The top of the support plate 8 is fixedly connected to the ozone generator 4. One end of the ozone generator 4 is fixedly connected to a guide pipe 22. One end of the guide pipe 22 is inserted through the reinforcing plate 20.

[0024] The second ultraviolet lamp 21 is electrically connected to the controller 17. One side of the controller 17 is fixedly connected to the fixing sleeve 16. The top of the reinforcing plate 20 is fixedly connected to the motor 6. One end of the output shaft of the motor 6 is fixedly connected to the stirring rod 19. The stirring rod 19 is inserted through the reinforcing plate 20 and is rotatably connected to the reinforcing plate 20.

[0025] Polypropylene raw material can be fed into sterilization chamber 2 via conveying pipe 1. The flow of raw material inside sterilization chamber 2 can be guided by connecting pipe 18, allowing the raw material to smoothly enter mixing tank 5. Support plate 18 can support and reinforce the bottom of ozone generator 4. Ozone generated by ozone generator 4 can be sent into mixing tank 5 via guide pipe 12 to assist in the mixing of ozone and raw material. Stirring rod 19 is driven by motor 6 to rotate. Stirring rod 19 can help raw material at different positions come into contact with ozone, thereby improving the mixing effect of raw material and ozone. The use of multiple ultraviolet lamps 21 can be controlled by controller 17. The ultraviolet lamps 21 can penetrate the transparent material of sterilization chamber 2, allowing the ultraviolet lamps 21 to irradiate the raw material and achieve sterilization treatment. Through ultraviolet irradiation and ozone dual sterilization, the sterilization effect of raw material can be guaranteed and the residue of microorganisms in raw material can be reduced.

[0026] Example 2: Figures 1-3 As shown, a discharge pipe 9 is fixedly connected to the bottom of the mixing tank 5. A guide pipe 23 is provided at the top of the discharge pipe 9. The bottom of the guide pipe 23 is inserted through the reinforcing plate 20. One end of the guide pipe 23 is fixedly connected to the processing box 3. The bottom of the processing box 3 is fixedly connected to the support plate 8. An exhaust fan 7 is fixedly connected to the top of the processing box 3. A filter plate 15 is snapped onto the inner wall of the processing box 3. An activated carbon adsorption layer 14 is provided at the top of the filter plate 15. One side of the activated carbon adsorption layer 14 is snapped onto the inner wall of the processing box 3. A reinforcing frame 13 is fixedly connected to the inner wall of the processing box 3. An ultraviolet lamp tube 12 is fixedly connected to the inner wall of the reinforcing frame 13. A catalytic decomposition layer 11 and an activated carbon adsorption layer 10 are arranged sequentially above the reinforcing frame 13. One side of both the catalytic decomposition layer 11 and the activated carbon adsorption layer 10 is snapped onto the inner wall of the processing box 3.

[0027] The polypropylene raw material inside the mixing tank 5 can be discharged through the discharge pipe 9. Air circulation between the mixing tank 5 and the treatment box 3 can be achieved through the guide pipe 23. The air flow inside the treatment box 3 can be accelerated by the exhaust fan 7, so that the gas inside the mixing tank 5 can enter the treatment box 3 more quickly. The filter plate 15 can achieve preliminary filtration of the waste gas. The activated carbon adsorption layer 14 and the activated carbon adsorption layer 10 can achieve dual adsorption of the waste gas, reducing the content of harmful substances in the waste gas. The reinforcing frame 13 can reinforce the installation of the ultraviolet lamp tube 12. The irradiation of the ultraviolet lamp tube 12 can achieve preliminary decomposition of the waste gas. The manganese dioxide inside the catalytic decomposition layer 11 can further decompose the waste gas, thereby ensuring the purification effect of the waste gas inside the treatment box 3.

[0028] The operating method and working principle of this device are as follows: First, the polypropylene raw material required for the polypropylene processing equipment is fed into the sterilization chamber 2 through the conveying pipe 1. The sterilization chamber 2 is made of transparent material. After the raw material enters the sterilization chamber 2, it is sterilized by irradiation with ultraviolet lamp tube 21. After sterilization, the raw material enters the mixing tank 5 through the connecting pipe 18. At this time, the valve on the guide pipe 22 is opened to send the ozone generated by the ozone generator 4 into the mixing tank 5. The stirring rod 19 is driven by the motor 6 to rotate and stir the raw material. After stirring, the raw material can be discharged from the discharge pipe 9 at the bottom of the mixing tank 5 and enter the polypropylene processing equipment for subsequent processing.

[0029] When it is necessary to treat the exhaust gas inside the mixing tank 5, open the valve on the guide pipe 23, and use the exhaust fan 7 to extract the excess air inside the treatment box 3, so that the exhaust gas inside the mixing tank 5 can be extracted and enter the treatment box 3 through the guide pipe 23. After being filtered by the filter plate 15, it is initially adsorbed by the activated carbon adsorption layer 14, then decomposed by the ultraviolet lamp tube 12, and then catalytically decomposed by passing through the catalytic decomposition layer 11 containing manganese dioxide. After being adsorbed by the activated carbon adsorption layer 10, it is discharged through the top of the treatment box 3.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
