A scraper ring 17 is provided on the outer wall of the lifting ring groove 13, and the scraper ring 17 slides against the inner wall of the tank 1. The scraper ring 17 not only provides stable support for the lifting groove and the tank 1, but also cleans the residual liquid on the tank 1 during cleaning, so that the tank 1 can be quickly put back into use after cleaning. A partition ring 14 is fixedly installed inside the lifting ring groove 13, and the partition ring 14 is lowered by... The lifting ring groove 13 is a water equalization chamber 15. A high-pressure nozzle 16 is installed at the bottom of the lifting ring groove 13 and is connected to the water equalization chamber 15. A transmission device 6, a large spiral lift 11 and a water inlet pipe 21 are installed on the top of the outer side of the tank body 1. The water inlet pipe 21 is connected to the water equalization chamber 15. The output end of the large spiral lift 11 is connected to the lifting ring groove 13. The output end of the transmission device 6 is connected to the stirring rack 18 and the input end of the large spiral lift 11 respectively. A clutch 7 is also installed between the transmission device 6 and the input end of the large spiral lift 11.

[0033] Preferably, the input end of the clutch 7 is connected to the output end of the transmission device 6. The input end of the transmission device 6 is equipped with a motor 5 to provide power to the equipment. The output end of the clutch 7 is fixedly equipped with a transmission shaft 10. The free end of the transmission shaft 10 is connected to the input end of the large spiral jack 11. This configuration realizes the connection between the transmission device 6 and the large spiral jack 11, ensuring the stable transmission of power between the transmission device 6 and the large spiral jack 11. A controller 8 is also fixedly installed on the top of the tank 1 on one side of the transmission device 6. The output end of the controller 8 is fixedly equipped with a connecting frame 9, which is connected to the control end of the clutch 7. This configuration realizes the control of the power transmission between the transmission device 6 and the large spiral jack 11.

[0034] Preferably, the lifting ring groove 13 at the top of the partition ring 14 is provided with a spring pipe 20, one end of the spring pipe 20 is connected with the water inlet pipe 21, and the other end of the spring pipe 20 penetrates the partition ring 14 and communicates with the water equalizing cavity 15, so that the communication between the water inlet pipe 21 and the water equalizing cavity 15 can be realized, and the movement of the lifting ring groove 13 will not be affected.

[0035] Preferably, the tank body 1 is provided with a feeding valve 19 at the top, and the tank body 1 is provided with a discharging valve 4 on the side wall, and the feeding valve 19 and the discharging valve 4 are detachably connected with the tank body 1 by threads, so that the feeding and discharging are facilitated, and the maintenance and replacement are also convenient.

[0036] Preferably, the tank body 1 is further provided with at least three supporting legs 2, so that the tank body 1 can be stably supported, and each supporting leg 2 is provided with a universal wheel 3, so that the tank body 1 can be moved and carried conveniently.

[0037] Preferably, the tank body 1 is further provided with a protective ring 12 fixedly arranged on the inside top, and the protective ring 12 is located between the stirring frame 18 and the lifting ring groove 13, so that the lifting ring groove 13 and the high-pressure spray head 16 can be protected.

[0038] Preferably, the high-pressure spray head 16 has at least two water outlets, and the output directions of the two water outlets are in inverted V distribution, so that the inside of the tank body 1 can be cleaned more thoroughly.

[0039] The working process of the embodiment is as follows: when the device is used, the worker can input the component raw materials to be mixed into the tank body 1 through the feeding valve 19, the motor 5 drives the transmission device 6 to rotate, and after the transmission device 6 rotates, the transmission device 6 drives the stirring frame 18 to rotate because the clutch 7 is in the disconnected state between the transmission device 6 and the large screw elevator 11, so that the component raw materials in the tank body 1 are stirred to be mixed and homogeneous.

[0040] When the components in the tank 1 are mixed, the workers open the discharge valve to discharge the mixed material, and after the material is completely discharged, the tank 1 needs to be cleaned. At this time, the workers connect the water inlet pipe 21 to the external high-pressure water source, and the external high-pressure water source flows into the spring pipe 20 from the water inlet pipe 21, and then flows into the water equalizing cavity 15 along the spring pipe 20, and finally is sprayed out at a very fast speed from the high-pressure spray head 16 to flush the inside of the tank 1; then the workers operate the controller 8, so that the controller 8 drives the clutch 7 to engage through the connecting frame 9, and the engaged clutch 7 transmits the power of the transmission device 6 to the large spiral elevator 11, and the large spiral elevator 11 outputs to push the lifting ring groove 13 to move downward, and in the process of moving downward of the lifting ring groove 13, the high-pressure spray head 16 flushes the inner wall of the tank 1, and at the same time the stirring frame 18 rotates under the drive of the transmission device 6, so that the spray head also flushes the stirring frame 18 in all directions, and because of the inverted V-shaped arrangement of the high-pressure spray head 16, the bottom of the tank 1 is also flushed in the process of the lifting ring groove 13 gradually approaching the bottom of the tank 1, realizing the comprehensive cleaning of the inside of the tank 1, and the sewage after cleaning is discharged through the discharge valve.

[0041] In the embodiment, in order to ensure that the lifting ring groove 13 can stably lift in the tank 1, at least two large spiral elevators 11 need to be installed on the tank 1, and need to be symmetrically distributed along the center of the tank 1, and the transmission device 6 is preferably a three-output shaft reducer, so that the large spiral elevator 11 can be driven to rotate while driving the stirring frame 18 to rotate.

[0042] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
