Description

Technical Field

[0001] The utility model relates to the technical field of material processing, in particular to a reaction kettle for polypropylene processing. Background Art

[0002] In the production process of polypropylene, the reactor plays a vital role as a key equipment. The reactor is a large container used to achieve efficient mixing, reaction and regulation of process conditions between chemical substances.

[0003] During the operation of the reactor, due to various physical and chemical reactions, materials are easily attached to the inner wall. Although some factories use scrapers to remove these impurities, this method is not very efficient because the scraped impurities may be lifted up again and attached to the inner wall as the reactor is stirred. This not only affects the quality and purity of the product, but also increases the difficulty of cleaning and may even cause premature wear of the equipment. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a reaction kettle for polypropylene processing.

[0005] The utility model is implemented by the following technical scheme: a polypropylene processing reactor, comprising an isolation cover, one side of the upper surface of the isolation cover is fixedly connected to a water storage tank, a water pump is fixedly installed on the inner bottom wall of the water storage tank by bolts, and a nozzle assembly is arranged at the output end of the water pump;

[0006] The nozzle assembly includes a connecting water pipe, one end of which is fixedly connected to the output end of the water pump, and the other end of the connecting water pipe is fixedly connected to a two-way delivery pipe, both ends of the two-way delivery pipe are fixedly connected to a water collecting chamber, grooves are provided on both sides of the middle part of the upper surface of the isolation cover, the water collecting chamber is arranged inside the groove, and high-pressure nozzles are fixedly connected to both sides of the outer surface of the water collecting chamber.

[0007] Through the above technical solution, appropriate cleaning liquid is pre-prepared in the water tank. The cleaning liquid can be acidic, alkaline or neutral, depending on the type of dirt accumulated on the inner wall of the reactor. Then the cleaning liquid or water in the water tank is transported to the high-pressure nozzle through a water pump to ensure that the cleaning liquid is sprayed to cover every corner and achieve the expected cleaning effect.

[0008] As a further improvement of the above solution, a filling port is provided on one side of the upper surface of the water storage tank, and a filling hole is provided on the other side of the upper surface of the isolation cover.

[0009] Through the above technical solution, the feeding hole is used to add raw materials or other chemical reagents into the reactor. Its location is designed on the other side of the isolation cover, which is convenient for operators to add materials continuously or intermittently during the operation of the reactor without frequently opening the isolation cover, thereby reducing the complexity of operation and potential safety risks.

[0010] As a further improvement of the above solution, a protective seat is fixedly connected to the middle of the upper surface of the isolation cover, and a servo motor is fixedly mounted on the inner wall of the protective seat by bolts.

[0011] Through the above technical solution, the presence of the protective seat can reduce the vibration and impact of the servo motor during operation and extend its service life.

[0012] As a further improvement of the above solution, the output end of the servo motor is fixedly connected to a transmission shaft, and both sides of the outer surface of the transmission shaft are fixedly connected to extension blocks.

[0013] Through the above technical solution, the transmission shaft serves as the mechanical output component of the servo motor, and its function is to transmit the rotational power of the servo motor to the extension block, thereby driving the scraper plate to perform circular motion.

[0014] As a further improvement of the above solution, a scraper plate is fixedly connected to the outer surface of the extension block, and a kettle body is arranged at the bottom of the isolation cover.

[0015] Through the above technical solution, the scraper plate can scrape the material on the inner wall of the reactor body during the operation of the reactor to keep it evenly mixed, while also preventing the material from staying on the inner wall for a long time and condensing or depositing, affecting product quality and reaction efficiency.

[0016] As a further improvement of the above solution, a reinforcement plate is sleeved on the outer surface of the kettle body, and the scraper plate is arranged inside the kettle body.

[0017] Through the above technical solution, the role of the reinforcement plate is to enhance the structural stability and supporting strength of the kettle body. During the operation of the reactor, especially under high pressure and high temperature conditions, the kettle body may be subjected to greater pressure and stress. The reinforcement plate can improve the pressure resistance of the kettle body and prevent it from being deformed or damaged due to excessive pressure, thereby ensuring the safety and reliability of the reaction process.

[0018] As a further improvement of the above solution, a support leg group is fixedly connected to the lower surface of the reinforcement plate.

[0019] Through the above technical solution, the presence of the support leg group can disperse the force borne by the reinforcement plate and the kettle body, so that the equipment remains stable during operation and unnecessary vibration is reduced, which helps to improve the service life and operating efficiency of the equipment.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a nozzle assembly, and personnel use a water pump to transport the cleaning liquid or water in the water tank to the high-pressure nozzle, ensuring that the cleaning liquid or water can be evenly sprayed to every corner of the kettle body. At this time, the servo motor drives the scraper plate to rotate to scrape off the deposited materials on the inner wall of the kettle body. The synergistic effect of the scraper plate and the high-pressure nozzle greatly improves the cleaning effect. When the scraper plate rotates, the stubborn materials attached to the inner wall of the kettle body can be scraped off. At the same time, the high-pressure water flow sprayed by the nozzle can wash away these materials to prevent them from attaching to the kettle body again, and to avoid the materials from staying on the inner wall for a long time and condensing and depositing, which affects the product quality and reaction efficiency.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Example:

[0031] Please combine Figure 1-5A polypropylene processing reactor of this embodiment comprises an isolation cover 1, a water storage tank 2 is fixedly connected to one side of the upper surface of the isolation cover 1, a water pump 3 is fixedly installed on the inner bottom wall of the water storage tank 2 by bolts, and a nozzle assembly 4 is provided at the output end of the water pump 3;

[0032] The nozzle assembly 4 includes a connecting water pipe 401, one end of which is fixedly connected to the output end of the water pump 3, and the other end of the connecting water pipe 401 is fixedly connected to a two-way delivery pipe 402, both ends of the two-way delivery pipe 402 are fixedly connected to a water collecting chamber 403, grooves are provided on both sides of the middle part of the upper surface of the isolation cover 1, the water collecting chamber 403 is arranged inside the groove, and both sides of the outer surface of the water collecting chamber 403 are fixedly connected to high-pressure nozzles 404, and appropriate cleaning liquid is pre-prepared in the water tank 2. The cleaning liquid can be acidic, alkaline or neutral, depending on the type of dirt accumulated on the inner wall of the reactor. Then the personnel transport the cleaning liquid or water in the water tank 2 to the high-pressure nozzle 404 through the water pump 3 to ensure that the spraying of the cleaning liquid covers every corner and achieves the expected cleaning effect.

[0033] A filling port 5 is provided on one side of the upper surface of the water storage tank 2, and a material adding hole 6 is provided on the other side of the upper surface of the isolation cover 1. The material adding hole 6 is used to add raw materials or other chemical reagents into the reactor. The material adding hole 6 is designed to be located on the other side of the isolation cover 1, so that the operator can add materials continuously or intermittently during the operation of the reactor without frequently opening the isolation cover 1, thereby reducing the complexity of the operation and potential safety risks.

[0034] A protective seat 7 is fixedly connected to the middle of the upper surface of the isolation cover 1, and a servo motor 8 is fixedly installed on the inner wall of the protective seat 7 by bolts. The existence of the protective seat 7 can reduce the vibration and impact of the servo motor 8 during operation and extend its service life.

[0035] The output end of the servo motor 8 is fixedly connected to a transmission shaft 9, and both sides of the outer surface of the transmission shaft 9 are fixedly connected to extension blocks 10. The transmission shaft 9 serves as a mechanical output component of the servo motor 8. Its function is to transmit the rotational power of the servo motor 8 to the extension block 10, thereby driving the scraper plate 11 to perform circular motion.

[0036] A scraper plate 11 is fixedly connected to the outer surface of the extension block 10, and a kettle body 12 is arranged at the bottom of the isolation cover 1. The scraper plate 11 is used to scrape the material on the inner wall of the kettle body 12 to keep it evenly mixed, and also to prevent the material from staying on the inner wall for a long time and condensing or depositing, which affects the product quality and reaction efficiency.

[0037] The outer surface of the kettle body 12 is sleeved with a reinforcement plate 13, and the scraper plate 11 is arranged inside the kettle body 12. The function of the reinforcement plate 13 is to enhance the structural stability and supporting strength of the kettle body 12. During the operation of the reactor, especially under high pressure and high temperature conditions, the kettle body 12 may be subjected to greater pressure and stress. The reinforcement plate 13 can improve the pressure resistance of the kettle body 12 and prevent it from being deformed or damaged due to excessive pressure, thereby ensuring the safety and reliability of the reaction process.

[0038] The lower surface of the reinforcement plate 13 is fixedly connected with a support leg group 14. The presence of the support leg group 14 can disperse the force borne by the reinforcement plate 13 and the kettle body 12, so that the equipment remains stable during operation and unnecessary vibration is reduced, thereby helping to improve the service life and operating efficiency of the equipment.

[0039] The implementation principle of a polypropylene processing reactor in the embodiment of the present application is as follows: personnel first pre-prepare appropriate cleaning liquid in the water tank 2. The cleaning liquid can be acidic, alkaline or neutral, depending on the type of dirt accumulated on the inner wall of the reactor. Then, personnel use the water pump 3 to transport the cleaning liquid or water in the water tank 2 to the high-pressure nozzle 404 to ensure that the cleaning liquid is sprayed to cover every corner and achieve the expected cleaning effect. At this time, by starting the servo motor 8, the rotational power of the servo motor 8 is transmitted to the extension block 10, thereby driving the scraper plate 11 to perform a circular motion. The function of the scraper plate 11 is to scrape off the material on the inner wall of the kettle body 12 to keep it evenly mixed, and at the same time prevent the material from staying on the inner wall for a long time and condensing or depositing, affecting the product quality and reaction efficiency. When the scraper plate 11 rotates, the kettle body can be scraped off. The stubborn substances attached to the inner wall of 12 can be washed away by the high-pressure water flow sprayed from the nozzle to prevent them from attaching to the kettle body 12 again, and to avoid the materials from staying on the inner wall for a long time and condensing and depositing, which will affect the product quality and reaction efficiency. The function of the reinforcement plate 13 is to enhance the structural stability and supporting strength of the kettle body 12. During the operation of the reactor, especially under high pressure and high temperature conditions, the kettle body 12 may be subjected to greater pressure and stress. The reinforcement plate 13 can improve the pressure resistance of the kettle body 12 and prevent it from being deformed or damaged due to excessive pressure, thereby ensuring the safety and reliability of the reaction process. The presence of the support leg group 14 can disperse the force borne by the reinforcement plate 13 and the kettle body 12, so that the equipment remains stable during operation and reduces unnecessary vibration, which helps to improve the service life and operating efficiency of the equipment.
