The heater 404 is fixedly installed on the left side of the premixing heating tank 2 and is fixedly connected to the electric heating tube 403. The lifting ring 405 is fixedly connected to the top of the installation frame 401.

[0028] Specifically, the number of the lifting rings 405 is set to four. A controller 5 is fixedly installed at the bottom of the heater 404. The heater 404 is electrically connected to the controller 5.

[0029] Furthermore, by setting four lifting rings 405, it is convenient for workers to use a hoisting machine to move the installation frame 401 and the electric heating tube 403, enhancing the stability during the hoisting process.

[0030] Specifically, a heat insulation layer 6 is fixedly installed on the outer surface of the installation frame 401. The heat insulation layer 6 is made of polyurethane heat insulation material and aluminum silicate heat insulation material.

[0031] Furthermore, through the setting of the heat insulation layer 6, the heat loss of the electric heating tube 403 can be prevented, the heating efficiency can be improved, and at the same time, the service life of the electric heating tube 403 can be extended.

[0032] Specifically, a top plate 7 is fixedly installed at the top of the installation cavity 3. A first sealing ring 8 is fixedly connected to the bottom of the top plate 7. The top plate 7 and the premixing heating tank 2 are fixedly connected by fastening bolts 9.

[0033] Furthermore, through the setting of the top plate 7 and the first sealing ring 8, it is convenient to seal the installation cavity 3 and ensure the closed state of the installation cavity 3.

[0034] Specifically, a top cover 10 is fixedly installed at the top of the premixing heating tank 2. A second sealing ring 11 is fixedly installed at the bottom of the top cover 10. An air-operated feeding port 12 is opened at the top of the top cover 10. An air-operated feeding pipe 13 is fixedly installed at the top of the air-operated feeding port 12. An electric feeding port 14 is opened on the front of the air-operated feeding port 12. An electric feeding pipe 15 is fixedly installed at the top of the electric feeding port 14.

[0035] Furthermore, the pneumatic feeding pipe 13 can be used for rapid feeding while ensuring good sealing performance.

These feeding methods can effectively improve work efficiency and ensure the uniformity of material mixing.

[0036] Specifically, a manual feeding port 16 is provided on the front of the electric feeding port 14, and a sealing cover 17 is fixedly installed on the top of the manual feeding port 16.

[0037] Furthermore, through the setting of the manual feeding port 16, it is convenient for workers to regularly feed high-boiling solvents and the like from the top inside the tank through the manual feeding port 16.

[0038] Specifically, a through hole 18 is provided on the left side of the electric feeding port 14. A motor 19 is fixedly installed on the top of the through hole 18. The output end of the motor 19 is fixedly installed with a rotating shaft 20. A mixing plate 21 is fixedly connected to the outer surface of the rotating shaft 20. One end of the mixing plate 21 close to the inner wall of the premixing and heating tank 2 is fixedly connected with a scraping plate 22. The motor 19 is electrically connected to the controller 5.

[0039] Furthermore, by starting the motor 19, the rotating shaft 20 can be driven to rotate through the output end. The rotating shaft 20 drives the mixing plate 21 to rotate. While the mixing plate 21 is rotating, the scraping plate 22 closely attached to the inner wall of the premixing and heating tank 2 also rotates synchronously. The scraping plate 22 scrapes the raw materials adhering to the inner wall of the premixing and heating tank 2, making the raw material mixing more sufficient.

[0040] Specifically, a discharge port 23 is provided at the bottom of the premixing and heating tank 2. A discharge valve 24 is fixedly installed at the bottom of the discharge port 23. A discharge pipe 25 is fixedly installed at the bottom of the discharge valve 24.

[0041] Furthermore, through the setting of the discharge valve 24, it is convenient to precisely control the output of the mixed material, facilitating subsequent filling of the material by workers.

[0042] During use, power on the heater 404 and the motor 19. Start the heating mechanism 4 through the controller 5. Then select an appropriate feeding method to put various raw materials to be mixed into the premixing and heating tank 2. Start the motor 19 through the controller 5. The motor 19 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the mixing plate 21 to rotate. While the mixing plate 21 is rotating, the scraping plate 22 closely attached to the inner wall of the premixing and heating tank 2 also rotates synchronously. The scraping plate 22 scrapes the raw materials adhering to the inner wall of the premixing and heating tank 2. The mixing plate 21 and the scraping plate 22 stir various raw materials. When the materials are fully mixed, output the materials through the discharge pipe 25. When a fault occurs in the heating function of the premixing device, remove the fastening bolt 9, open the top plate 7, lift the installation frame 401 with other tools, and take out the installation frame 401 and the electric heating tube 403 from the premixing and heating tank 2. Then the staff can repair and maintain the taken-out electric heating tube 403, and after the repair, install the installation frame 401 and the electric heating tube 403 in the installation cavity 3 again.

[0043] In summary, through the combined use of the installation frame 401 and the lifting ring 405, the electric heating tube 403 can be easily taken out from the premixing and heating tank 2, which is convenient for repair and maintenance, improving the convenience of device maintenance. Since the electric heating tube 403 is movable, it can be conveniently disassembled and replaced. Therefore, the temperature inside the premixing and heating tank 2 can be better maintained, improving production efficiency and product quality. The design of the installation frame 401 can also provide better structural stability, ensuring that the electric heating tube 403 is more stably installed in the inner wall of the premixing and heating tank 2 without phenomena such as shaking or falling off.
