The steel-lined reactor made of roto-molded fluorine material can prevent the raw materials from sticking to the inner wall of the reactor when stirring the raw materials by arranging an anti-sticking component, thereby saving a large amount of resources. At the same time, by arranging an anti-sticking component, stirring and anti-sticking can be carried out simultaneously. By arranging an F40 coating, the reactor can have good corrosion resistance and also have good negative pressure resistance."

Figure 1-4A steel-lined reactor comprises a reactor body 1, a sealing cover 2 is arranged at the upper end of the reactor body 1 for sealing the reactor body 1, a stirring mechanism 3 is arranged on the sealing cover 2 for stirring the material in the reactor body 1, a connecting plate 4 is arranged on the stirring mechanism 3, a groove 5 is arranged on one side of the connecting plate 4, an electromagnet 6 is arranged in the groove 5, a cleaning mechanism 7 is arranged on the connecting plate 4, and the cleaning mechanism 7 cooperates with the electromagnet 6 to clean the inner wall of the reactor body 1;

[0032] Reference Figure 2 The stirring mechanism 3 includes a stirring rod 301, a plurality of stirring blades 302 and a motor 303. The stirring rod 301 is rotatably arranged at the inner top end of the sealing cover 2. The bottom end of the stirring rod 301 is located inside the reactor body 1, and one end of the connecting plate 4 is connected to the stirring rod 301. The plurality of stirring blades 302 are all arranged on the outer side of the stirring rod 301 for stirring and mixing the materials in the reactor body 1. The motor 303 is arranged at the upper end of the sealing cover 2. The output shaft of the motor 303 is connected to the top end of the stirring rod 301 for driving the stirring rod 301 to rotate.

[0033] By adopting the above technical solution, after the material is poured into the reactor body 1 , the motor 303 can drive the stirring rod 301 to rotate, and the rotation of the stirring rod 301 can drive the stirring blade 302 to rotate, and the material in the reactor body 1 can be stirred by the stirring blade 302 .

[0034] Reference Figure 3 The cleaning mechanism 7 includes a connecting rod 701, a magnetic block 702, a scraper 703 and a spring 704. The connecting rod 701 is inserted into the groove 5, and one end of the connecting rod 701 passes through the groove 5. The magnetic block 702 is arranged at one end of the connecting rod 701 located in the groove 5, and the magnetic block 702 is magnetically attracted to the electromagnet 6. The scraper 703 is arranged at one end of the connecting rod 701 away from the magnetic block 702, and is used to clean the inner wall of the reactor body 1. The spring 704 is sleeved on the outer side of the connecting rod 701, and the two ends of the spring 704 are respectively connected to the inner wall of the groove 5 and the magnetic block 702, and are used to drive the scraper 703 to fit the inner wall of the reactor body 1.

[0035] By adopting the above technical solution, when it is necessary to clean the inner wall of the reactor body 1, the electromagnet 6 stops working, and the adsorption force on the magnetic block 702 disappears at this time, and the elastic force of the spring 704 can make the connecting rod 701 move, and the movement of the connecting rod 701 makes the scraper 703 move and contact the inside of the reactor body 1, so that when the motor 303 works again, the stirring rod 301 can drive the scraper 703 to rotate, and then the scraper 703 can clean the inner wall of the reactor body 1, and after the cleaning of the inner wall of the reactor body 1 is completed, the scraper 703 can be reset and not contact the inner wall of the reactor body 1, so that the wear of the scraper 703 is greatly reduced, and the protection of the reactor body 1 is improved.

[0036] Reference Figure 4 A cavity 8 is provided inside the scraper 703 , and an electric heating tube 9 is provided in the cavity 8 .

[0037] By adopting the above technical solution, when the scraper 703 rotates to clean the inner wall of the reactor body 1, the electric heating tube 9 works, so that the surface temperature of the scraper 703 in contact with the inner wall of the reactor body 1 increases, which helps to soften or dissolve the substances remaining on the inner wall of the reactor body 1, making it easier to be removed by the scraper 703.

[0038] Reference Figure 1 A feed pipe 10 is disposed at the upper end of the sealing cover 2 , a discharge pipe 11 is disposed at the bottom end of the reactor body 1 , and valves 12 are disposed on both the feed pipe 10 and the discharge pipe 11 .

[0039] By adopting the above technical solution, it is convenient to pour the material into the interior of the reactor body 1 through the feed pipe 10, and it is convenient to discharge the stirred material through the discharge pipe 11.

[0040] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch. First, the material is poured into the interior of the reactor body 1 through the feed pipe 10, and then the motor 303 works to drive the stirring rod 301 to rotate, and the stirring rod 301 rotates to drive the stirring blade 302 to rotate. The material in the reactor body 1 can be stirred by the stirring blade 302, and then the material can be discharged through the discharge pipe 11 after the stirring is completed. When the inner wall of the reactor body 1 needs to be cleaned, the electromagnet 6 stops working, and the magnetic block 702 is When the adsorption force disappears, the elastic force of the spring 704 can move the connecting rod 701, and the movement of the connecting rod 701 causes the scraper 703 to move and contact the inside of the reactor body 1, so that when the motor 303 works again, the stirring rod 301 can drive the scraper 703 to rotate, and then the scraper 703 can clean the inner wall of the reactor body 1. When the inner wall of the reactor body 1 is not cleaned, the electromagnet 6 works so that the scraper 703 does not contact the inner wall of the reactor body 1, which greatly reduces the wear of the scraper 703 and improves the protection of the reactor body 1.

[0041] When the utility model is in use, the use position of the scraper 703 is easily adjusted, so that the inner wall of the reactor body 1 can be cleaned conveniently. At the same time, when the inner wall of the reactor body 1 is not cleaned, the scraper 703 does not contact the inner wall of the reactor body 1, which greatly reduces the wear of the scraper 703 and improves the protection of the reactor body 1.
