The technology describes a tank comprising "a base and a mixer frame fixedly mounted on the base. An insulated outer tank is fixedly mounted on the top of the base. An annular groove is formed at the top of the insulated outer tank, and an inner mixing tank is placed in the annular groove. A cross-shaped slot is formed at the bottom of the inner mixing tank. A bottom pad is fixedly mounted on the bottom of the inner wall of the insulated outer tank, and a cross-shaped insert is fixedly mounted on the top of the bottom pad. Evenly distributed electric heating tubes are fixedly installed on the inner side wall of the insulated outer tank. An electrically controlled hydraulic cylinder is fixedly mounted on the top of the mixer frame, and a tank cover is fixedly mounted on the bottom of the electrically controlled hydraulic cylinder. A geared motor is fixedly mounted on the top of the tank cover." However, this existing technology lacks a cleaning structure, making cleaning inconvenient. Residue inside the tank may cause cross-contamination, affecting the uniformity of composition and performance stability of the next batch of products. Therefore, designing a mixing tank for silicone rubber processing is essential. Utility Model Content

[0004] The purpose of this invention is to provide a mixing tank for silicone rubber processing, which solves the problems in related technologies such as the lack of a cleaning structure during use, inconvenient cleaning, and potential cross-contamination from residues inside the tank.

[0005] The technical solution of this utility model is as follows:

[0006] A mixing tank for processing silicone rubber includes a tank body. A tank cover is threaded onto the top of the tank body, and a spray frame is threaded onto the bottom of the tank cover. A plurality of spray nozzles are threaded onto the bottom of the spray frame at equal intervals. A water inlet pipe is provided at the top of the spray frame, and one end of the water inlet pipe passes through the tank cover. A heating groove is formed on the bottom end face of the tank cover, and an electric heating element is threaded into the interior of the heating groove. An inner liner is inserted into the interior of the tank body. A mixing frame is threaded onto the center of the bottom of the tank cover, and telescopic grooves are formed on both sides of the bottom of the mixing frame. A mixing rod is inserted into the interior of the telescopic grooves. A wing screw is threaded onto the top of the telescopic groove, and one end of the wing screw extends into the telescopic groove and fits against the mixing rod. A top frame is provided below the bottom of the tank cover, and electric push rods are threaded onto all four sides of the bottom of the top frame. One end of the electric push rod is threaded and fixed to the bottom of the inner wall of the tank body.

[0007] Preferably, the spray frame is annular, the stirring rod is L-shaped, and both the tank and the inner liner are made of stainless steel.

[0008] Preferably, a number of ball bearings are equidistantly engaged on the top end face of the top frame, a bracket is welded to the bottom of the top frame, and a motor is screwed onto the bracket. The output end of the motor is screwed and fixed to the bottom end face of the inner liner.

[0009] Preferably, the outer wall of the inner liner is screwed with a plurality of rollers at equal intervals, and the outer wall of the rollers is in contact with the inner wall of the tank.

[0010] Preferably, a four-way adapter is screwed to the bottom end face of the tank, and a fan is provided below the bottom of the four-way adapter. The output end of the fan is connected to the inside of the four-way adapter.

[0011] Preferably, each of the four air outlets of the four-way adapter is connected to a ventilation pipe, and air outlet pipes are screwed onto all four sides of the outer wall of the tank, with the other end of the ventilation pipe connected to the bottom of the air outlet pipe.

[0012] Preferably, a base is welded to the bottom end face of the tank body, and an air valve is screwed to the top end face of the tank cover.

[0013] Preferably, the base is frustum-shaped, and the bottom diameter of the base is larger than that of the tank.

[0014] The beneficial effects of this utility model are:

[0015] By pulling the stirring rod outward, its outer wall can fit against the inner wall of the inner tank. Tightening the wing-shaped screws secures the stirring rod. Clean water is supplied to the spray nozzle through the water inlet pipe and flows into the inner tank. The motor is then restarted to rotate the inner tank, allowing the stirring rod to scrape away residual silicone rubber. The electric push rod lifts the inner tank, enabling cleaning of different areas and improving cleaning efficiency. After cleaning, the wastewater is poured out, and the heating element is turned on for drying, accelerating the drying process. This method allows for convenient cleaning of the tank after stirring, preventing cross-contamination from residues and ensuring the uniformity and stability of the next batch of products. Furthermore, the stirring rack is removable for easy cleaning of both the rack and the stirring rod.

[0016] The ball bearings ensure smoother rotation of the inner tank, while the rollers enhance its stability. A four-way adapter disperses the air input from the blower, and a ventilation duct directs this dispersed air to the corresponding outlet pipe. Exhausting the air through the outlet pipe accelerates airflow, improves heat dissipation, and prevents excessive internal temperature from affecting the mixing process. An air valve allows for proper venting during mixing to prevent the silicone rubber from overflowing due to over-boiling. An electric push rod extends and retracts to adjust the position of the top frame, thereby adjusting the mixing position of the inner tank. Attached Figure Description

[0024] like Figure 1-4As shown, this embodiment proposes a mixing tank for silicone rubber processing, including a tank body 1. A tank cover 2 is threaded onto the top of the tank body 1, and a spray frame 3 is screwed onto the bottom of the tank cover 2. A plurality of spray nozzles 4 are screwed onto the bottom of the spray frame 3 at equal intervals. A water inlet pipe 5 is provided at the top of the spray frame 3, and one end of the water inlet pipe 5 passes through the tank cover 2. A heating groove 6 is provided on the bottom end face of the tank cover 2, and an electric heating tube 7 is screwed into the inside of the heating groove 6. An inner liner 8 is inserted into the inside of the tank body 1. A mixing frame 9 is screwed onto the center of the bottom of the tank cover 2, and telescopic grooves 10 are provided on both sides of the bottom of the mixing frame 9. A mixing rod 11 is inserted into the inside of the telescopic groove 10, and the top of the telescopic groove 10 passes through the tank body 1. A wing-shaped screw 12 is threaded on, with one bottom end of the wing-shaped screw 12 extending into the telescopic groove 10 and fitting against the stirring rod 11. A top frame 13 is located below the bottom of the tank lid 2, and electric push rods 14 are screwed onto the bottom of the top frame 13. One bottom end of the electric push rod 14 is screwed and fixed to the bottom of the inner wall of the tank body 1. The spray frame 3 is annular, and the stirring rod 11 is L-shaped. Both the tank body 1 and the inner liner 8 are made of stainless steel. Several ball bearings 15 are equidistantly engaged on the top end face of the top frame 13. A bracket 16 is welded to the bottom of the top frame 13, and a motor 17 is screwed onto the bracket 16. The output end of the motor 17 is screwed and fixed to the bottom end face of the inner liner 8. Motor 17 drives inner liner 8 to rotate. Ball bearings 15 ensure smoother rotation of inner liner 8. Support bracket 16 supports motor 17. Several rollers 18 are equidistantly screwed onto the outer wall of inner liner 8, with the outer walls of the rollers 18 fitting against the inner wall of tank 1. The rollers 18 improve the stability of inner liner 8 during rotation. A four-way adapter 19 is screwed onto the bottom end face of tank 1, and a fan 20 is located below the bottom of the four-way adapter 19. The output end of fan 20 is connected to the internal insertion of the four-way adapter 19, allowing the air input from fan 20 to be dispersed. Each of the four outlet ends of the four-way adapter 19 is connected to... Ventilation pipe 21, and air outlet pipe 22 are screwed to all four sides of the outer wall of the tank body 1. The other end of the ventilation pipe 21 is inserted and connected to the bottom of the air outlet pipe 22. The air dispersed by the four-way adapter 19 can be delivered to the corresponding air outlet pipe 22 through the ventilation pipe 21. The air outlet pipe 22 is used to exhaust the air, which can accelerate the air circulation and improve the heat dissipation effect. A base 23 is welded to the bottom end face of the tank body 1. An air valve 24 is screwed to the top end face of the tank cover 2.

In use, by removing the can lid 2 and adding silicone rubber material to the inner liner 8 in batches, then closing the can lid 2 and starting the motor 17, the inner liner 8 can rotate, thereby stirring the silicone rubber material. The ball bearing 15 makes the rotation of the inner liner 8 smoother, and the roller shaft 18 improves the stability of the inner liner 8 during rotation. The four-way adapter 19 disperses the air input from the fan 20, and the ventilation pipe 21 delivers the dispersed air from the four-way adapter 19 to the corresponding air outlet pipe 22. The air outlet pipe 22 discharges the air, accelerating air circulation, improving heat dissipation, and preventing the internal temperature of the can 1 from becoming too high, which would affect the stirring process. The effect is achieved by using the air valve 24 to release air appropriately during the stirring process to prevent the silicone rubber from overflowing due to excessive boiling. The position of the top frame 13 is adjusted by using the electric push rod 14 to adjust the stirring position of the inner liner 8. After stirring, the lid 2 is opened and the silicone rubber in the inner liner 8 is removed. The stirring rod 11 is pulled outward so that the outer wall of the stirring rod 11 can fit against the inner wall of the inner liner 8. The wing screw 12 is tightened to press and fix the stirring rod 11. Clean water is supplied to the spray frame 3 through the water inlet pipe 5. The clean water flows into the inner liner 8 through the spray nozzle 4. The motor 17 is started again to drive the inner liner 8 to rotate, which can make the stirring rod 11 scrape off the silicone rubber remaining on the inner liner 8. The inner liner 8 is raised and lowered by using the electric push rod 14 to clean different positions, which improves the cleaning effect. After cleaning, the wastewater is poured out and the electric heating tube 7 is turned on to dry and accelerate the drying process.
