Fixed shells 16 are fixedly connected to both ends of the fixed pipe 12. The two fixed shells 16 are respectively in contact with the two movable shells 15. Rotating shafts 17 are rotatably connected to the inner walls of the two rotating sleeves 14. Cleaning brushes 18 are fixedly connected to the bottom ends of the two rotating shafts 17. The cleaning brushes 18 are located inside the movable shells 15. An electric telescopic rod 2 is fixedly connected to the top of the reactor body 1. The output end of the electric telescopic rod 2 is fixedly connected to a sliding rod 21. The sliding rod 21 is slidably connected to the reactor body 1. The bottom end of the sliding rod 21 is fixedly connected to a fixed block 22. A sliding ring 23 is rotatably connected to the fixed block 22. The sliding ring 23 is slidably connected to the rotating pipe 11. Mounting blocks 24 are fixedly connected to both sides of the sliding ring 23 and the tops of the two movable pipes 13 respectively.

Second racks 51 are fixedly connected to the two U-shaped rods 5. Second gears 52 are fixedly connected to the two rotating sleeves 14. The two second gears 52 are respectively meshed with the two second racks 51. Through the setting of the cleaning unit, the electric telescopic rod 2 drives the sliding rod 21, the fixed block 22, and the sliding ring 23 to move downward. The movement of the sliding ring 23 drives the movable pipes 13 to move outward through the mounting blocks 24 and the connecting rod 25. The movement of the movable pipes 13 drives the rotating sleeves 14, the movable shells 15, the rotating shafts 17, and the cleaning brushes 18 to move. With the cooperation of the second gears 52 and the second racks 51, the rotating sleeves 14 and the movable shells 15 rotate 180°. The motor 111 drives the rotating pipe 11 to rotate through the two transmission gears 112. The rotation of the rotating pipe 11 drives the fixed pipe 12, the movable pipes 13, the rotating sleeves 14, the movable shells 15, and the cleaning brushes 18 to rotate, so that the cleaning brushes 18 rotate circumferentially to clean the inner wall of the reactor body 1. When the fixed shell 16 and the movable shell 15 are combined, they can form a stirring rod, and the cleaning brushes 18 are accommodated in the stirring rod, realizing that the cleaning brushes 18 can be accommodated in the stirring rod. When the stirring rod is separated, the cleaning brushes 18 can clean the inner wall of the reactor body 1, thus facilitating the cleaning of the inner wall of the equipment.

[0023] Furthermore, sliding blocks 53 are fixedly connected to both of the two movable pipes 13. The two sliding blocks 53 are respectively slidably connected to the two U-shaped rods 5. Through the setting of the sliding blocks 53, the stability of the movable pipes 13 is improved.

[0024] Further, at the top ends of the two rotating shafts 17, there are fixedly connected first gears 19, and on the inner wall of the reactor body 1, there is fixedly connected an annular rack 110. The two first gears 19 and the annular rack 110 are on the same horizontal plane. Through the arrangement of the first gears 19, when the first gears 19 contact the annular rack 110, the cleaning brushes 18 contact the inner wall of the reactor body 1, causing the first gears 19 to rotate and self-rotate on the annular rack 110. The rotation of the first gears 19 drives the rotating shafts 17 and the cleaning brushes 18 to self-rotate, enabling the cleaning brushes 18 to self-rotate while rotating circumferentially, thereby improving the cleaning effect on the inner wall of the reactor body 1.

[0025] Further, the water spraying unit includes an outer connecting pipe 113 rotatably connected to the top end of the rotating pipe 11. Two connecting hoses 7 are fixedly connected and communicated between the two movable pipes 13 and the two movable shells 15 respectively. A plurality of water spraying holes 6 are formed in the two movable shells 15. Through the arrangement of the water spraying unit, water enters the fixed pipe 12 and the movable pipes 13 through the outer connecting pipe 113 and the rotating pipe 11. Since the movable shell 15 is a cavity, the water in the movable pipe 13 enters the movable shell 15 through the connecting hose 7 and then is sprayed out through the plurality of water spraying holes 6, thereby enabling the reactor body 1 to be cleaned by spraying water.

[0026] Further, at the bottom ends of the two movable pipes 13, there are both fixedly connected connecting blocks 3. A telescopic cross frame 31 is rotatably connected between the two connecting blocks 3. A water spraying pipe 32 is fixedly connected to the telescopic cross frame 31. The bottom of the fixed pipe 12 is fixedly communicated with a water outlet pipe 33. The water outlet pipe 33 is located directly above the water spraying pipe 32. Two movable rods 34 are slidably connected to the water outlet pipe 33. The top ends of the two movable rods 34 are fixedly connected together with a cover plate 35. Through the arrangement of the water spraying pipe 32, the movement of the two movable pipes 13 drives the telescopic cross frame 31 to contract. The contraction of the telescopic cross frame 31 drives the water spraying pipe 32 to move upward into the water outlet pipe 33 and lift the cover plate 35, enabling the water in the fixed pipe 12 to enter the water spraying pipe 32, so that the water spraying pipe 32 sprays water on the inner wall of the reactor body 1, improving the flushing effect on the inner wall of the reactor body 1. When the telescopic cross frame 31 extends, it can play a stirring effect.

[0027] Further, a cylindrical block 26 is fixedly connected to the sliding rod 21. A valve 27 is installed on the rotating pipe 11. The valve 27 is located directly below the cylindrical block 26. A torsion spring 28 is sleeved on the valve 27. The two ends of the torsion spring 28 are fixedly connected to the valve 27 and the rotating pipe 11 respectively. Through the arrangement of the valve 27, the downward movement of the sliding rod 21 drives the cylindrical block 26 to move downward, causing the cylindrical block 26 to move and squeeze the valve 27 to rotate and open. The rotation of the valve 27 drives the torsion spring 28 to rotate and undergo elastic deformation, thereby being able to automatically open the valve 27.

[0028] Further, the extrusion unit includes mounting shells 4 respectively fixedly connected to two fixed shells 16. Slide columns 41 are slidably connected to both of the two mounting shells 4. Rotating rods 42 are rotatably connected to the bottom ends of the two slide columns 41. An expansion rod 43 is rotatably connected to every two of the rotating rods 42.

Hypotenuse rings 48 are fixedly sleeved on both of the two cleaning brushes 18. The two fixed bars 47 are respectively located at the tops of the two hypotenuse rings 48. Through the arrangement of the extrusion unit, when the cleaning brush 18 moves outwards, it drives the hypotenuse ring 48 to move outwards. When the hypotenuse ring 48 moves away from the fixed bar 47, the return spring 46 drives the fixed bar 47, the slide column 41, the rotating rod 42 and the expansion rod 43 to move downwards, so that the rotating rod 42 is attached to the surface of the inclined plane. When the fixed tube 12 drives the fixed shell 16, the mounting shell 4, the slide column 41 and the rotating rod 42 to rotate, the rotating rod 42 can scrape and clean the inclined plane at the bottom of the reaction kettle body 1. When the rotating rod 42 moves away from the inclined plane at the bottom of the reaction kettle body 1, the expansion rod 43 and the two rotating rods 42 form a triangular structure, and thus can stir the materials at the bottom of the reaction kettle body 1. A plurality of round holes 44 are provided in the two expansion rods 43, and the plurality of round holes 44 in the two expansion rods 43 are arranged in a staggered manner, improving the stirring effect on the materials.

[0029] Specific implementation steps: Start the electric telescopic rod 2 to drive the sliding rod 21 to move downward. The movement of the sliding rod 21 drives the fixed block 22 and the sliding ring 23 to move downward. The movement of the sliding ring 23 drives the movable tube 13 to move outward through the mounting block 24 and the connecting rod 25. The movement of the movable tube 13 drives the rotating sleeve 14, the movable shell 15, the rotating shaft 17 and the cleaning brush 18 to move, so that the movable shell 15 moves away from the fixed shell 16. The movement of the rotating sleeve 14 drives the second gear 52 to move. When the second gear 52 moves to the position of the second rack 51, the second gear 52 moves on the second rack 51 and rotates 180° by itself. The rotation of the second gear 52 drives the rotating sleeve 14, the movable shell 15, the rotating shaft 17 and the cleaning brush 18 to rotate, so that the cleaning brush 18 faces the inner wall of the reaction kettle body 1. Until the first gear 19 contacts the circular ring rack 110, the cleaning brush 18 contacts the inner wall of the reaction kettle body 1. The motor 111 drives the rotating tube 11 to rotate through two transmission gears 112. The rotation of the rotating tube 11 drives the fixed tube 12, the movable tube 13, the rotating sleeve 14, the movable shell 15 and the cleaning brush 18 to rotate, so that the cleaning brush 18 rotates circumferentially to clean the inner wall of the reaction kettle body 1. When the fixed shell 16 and the movable shell 15 are combined, they can form a stirring rod, and the cleaning brush 18 is stored in the stirring rod. It realizes that the cleaning brush 18 can be stored in the stirring rod. When the stirring rod is separated, the cleaning brush 18 can clean the inner wall of the reaction kettle body 1, thus facilitating the cleaning of the inner wall of the equipment. The rotation of the rotating sleeve 14 drives the rotating shaft 17 and the first gear 19 to rotate, so that the first gear 19 rotates on the circular ring rack 110 and rotates by itself. The rotation of the first gear 19 drives the rotating shaft 17 and the cleaning brush 18 to rotate by itself, so that the cleaning brush 18 can rotate by itself while rotating circumferentially, thereby improving the cleaning effect on the inner wall of the reaction kettle body 1. The downward movement of the sliding rod 21 drives the cylindrical block 26 to move downward, so that the cylindrical block 26 moves to squeeze the valve 27 to rotate and open. The rotation of the valve 27 drives the torsion spring 28 to rotate and undergo elastic deformation, and then the valve 27 can be automatically opened, so that water enters the fixed tube 12 and the movable tube 13 through the outer connecting pipe 113 and the rotating tube 11. Since the movable shell 15 is a cavity, the water in the movable tube 13 enters the movable shell 15 through the connecting hose 7 and then is sprayed out by a plurality of spray holes 6, and then the reaction kettle body 1 can be sprayed and cleaned. The movement of the two movable tubes 13 drives the telescopic cross frame 31 to contract. The contraction of the telescopic cross frame 31 drives the spray pipe 32 to move upward into the water outlet pipe 33 and pushes up the cover plate 35, so that the water in the fixed tube 12 enters the spray pipe 32, and the spray pipe 32 sprays water on the inner wall of the reaction kettle body 1, improving the flushing effect on the inner wall of the reaction kettle body 1. When the telescopic cross frame 31 extends, it can play a stirring effect. When the cleaning brush 18 moves outward, it drives the bevel ring 48 to move outward. When the bevel ring 48 moves away from the fixed strip 47, since the return spring 46 is in a compressed state,The reset spring 46 drives the fixed strip 47, the sliding column 41, the rotating rod 42 and the telescopic rod 43 to move downward. When the two rotating rods 42 contact the bottom inclined surface of the reactor body 1, under the action of the elastic sheet 45, the two rotating rods 42 are attached to the surface of the inclined surface. The rotation of the rotating rod 42 drives the telescopic rod 43 to extend. When the fixed pipe 12 drives the fixed shell 16, the mounting shell 4, the sliding column 41 and the rotating rod 42 to rotate, the rotating rod 42 can scrape and clean the bottom inclined surface of the reactor body 1. When the rotating rod 42 moves away from the bottom inclined surface of the reactor body 1, the telescopic rod 43 and the two rotating rods 42 form a triangular structure, thereby being able to stir the materials at the bottom of the reactor body 1. The two telescopic rods 43 are provided with a plurality of round holes 44, and the plurality of round holes 44 of the two telescopic rods 43 are arranged in a staggered manner, improving the stirring effect on the materials.
