In the production of chemicals like adhesives, styrene is added and mixed with other powders to create prepolymers or composite materials. During the stirring process, due to the volatility of styrene, the styrene-to-powder mixture can adhere to the top of the stirred tank, making it difficult to clean with conventional cleaning equipment.

[0003] Therefore, the above problems need to be solved urgently. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the utility model provides a stirring tank cleaning device for cleaning the colloid residue in the stirring tank, solving the problem that the traditional cleaning device cannot clean the top of the tank body. No static electricity or open flame is generated during the cleaning process, ensuring the safety of the cleaning process, avoiding the bristles of the cleaning brush from falling off, and avoiding pollution.

[0005] Technical Solution: To achieve the above-mentioned objectives, the present invention provides a stirring kettle cleaning device, comprising a telescopic rod, one end of which is connected to a motor, which drives a rotating chuck connected to a flexible cleaning brush. A bending joint is connected between the telescopic rod and the motor, one end of which is connected to the telescopic rod. The bending joint is connected to the motor via a pipe, and the bending joint adjusts the angle between the telescopic rod and the motor. The motor drives the rotating chuck to rotate, which drives the flexible cleaning brush to clean the interior of the stirring kettle. The motor is a speed-controlled motor. During use, the telescopic rod extends into the stirring kettle through the observation window. The motor is started, which drives the flexible cleaning brush to rotate and clean the interior of the stirring kettle. The telescopic rod extends, allowing the flexible cleaning brush to clean the deep inside of the stirring kettle. The angle between the telescopic rod and the motor is adjusted by the bending joint to clean the top of the stirring kettle. Using the flexible cleaning brush to clean the interior of the stirring kettle does not generate static electricity or open flames, ensuring the safety of the cleaning process and preventing bristles from falling off the cleaning brush, thereby preventing contamination.

[0006] Furthermore, in the above-mentioned stirring tank cleaning device, an air jet block is provided between the rotating chuck and the motor, and the motor shaft of the motor passes through the air jet block and is connected to the rotating chuck. The air jet block is connected to an air pipe, and the air jet block blows air outward to remove powder adhering to the inner wall of the stirring tank.

[0007] Furthermore, in the aforementioned stirred tank cleaning device, a flat bearing is provided on the side of the jet block proximal to the rotating chuck. The flat bearing is retained within a groove provided in the jet block, and the end of the flat bearing distal to the jet block abuts the rotating chuck. The motor shaft of the motor passes through a through slot provided in the rotating chuck. A nut is screwed onto the end of the motor shaft distal to the jet block, which presses the rotating chuck against the underside of the flat bearing. Rotation of the motor shaft drives the rotating chuck.

[0008] Furthermore, in the aforementioned stirring tank cleaning device, the air jet block is equipped with a hollow channel, air holes, and an air inlet nozzle. The hollow channel is arranged along the axis of the air jet block, and the air holes are located on the side walls of the air jet block. The air holes are arranged in an array around the axis of the air jet block. The hollow channel and the air holes are connected, and the air inlet nozzle is connected to the hollow channel. Sealing rings are provided at both ends of the hollow channel, through which the motor of the motor passes. The air inlet nozzle is connected to the air pipe, and compressed air enters the hollow channel from the air inlet nozzle and is discharged from the air hole. The compressed air blows away the powder adhering to the inner wall of the stirring tank.

[0009] Furthermore, in the aforementioned stirring kettle cleaning device, the flexible cleaning brush is a disc brush made of silicone. The disc brush comprises a circular disc with silicone particles densely distributed along its surface. A connecting post is provided on one side of the disc, connecting the connecting post to the rotating chuck. The silicone disc brush's soft material prevents wear on the inner wall of the stirring kettle, damage to the stirring shaft, and contamination caused by bristle falling. It also eliminates static electricity and flames, improving cleaning safety. The disc's structure, combined with its soft material, allows it to conform to the shape of the stirring kettle's top surface, improving cleaning efficiency.

[0010] Furthermore, in the aforementioned stirring kettle cleaning device, the flexible cleaning brush is configured as a strip brush. The strip brush is made of silicone and has a metal strip at its center. Multiple protrusions are provided around the metal strip. The strip brush is folded in half, and its ends are connected to a rotating chuck. The strip brush with the metal strip at its center can be fixed into a desired shape as needed. A longer strip brush can also be installed, extending the cleaning device to meet deep cleaning needs. Simultaneously, when the strip brush is rotated at high speed, it is subjected to centrifugal force, forming an elliptical shape, which facilitates cleaning the top surface of the stirring kettle. The elliptical shape formed by the strip brush deforms with the object it contacts, conforming to the surface and improving cleaning efficiency.

[0011] Furthermore, in the aforementioned mixing tank cleaning device, the telescopic rod comprises an outer connecting rod and an inner connecting rod. The inner connecting rod extends into the outer connecting rod and slides within the outer connecting rod. A locking portion is provided at the connecting end of the outer and inner connecting rods, which locks the inner connecting rod. The telescopic rod can be extended to facilitate cleaning deep within the mixing tank, while shortened for easy storage. This also allows a worker to fully extend the cleaning device into the mixing tank, allowing the worker to conveniently position the telescopic rod horizontally to clean the top of the mixing tank.

[0012] Furthermore, in the above-mentioned stirring tank cleaning device, the rotating chuck includes a column, the column is provided with a clamping part, the clamping part is connected to a clamping block, the clamping block is provided with a through hole, a screw is passed through the through hole, and the clamping block presses the flexible cleaning brush to the clamping part.

[0013] Furthermore, in the aforementioned stirring kettle cleaning device, the bending joint includes a connecting seat, a bending seat, and a locking rod. The connecting seat has two connecting portions, the bending seat is inserted between the two connecting portions, and the locking rod passes through through-holes provided in the connecting seat and the bending seat, thereby locking the connecting seat and the bending seat. The contact surfaces of the connecting seat and the bending seat are each provided with a non-slip texture. One end of the locking rod has a plum blossom head, and the other end of the locking rod is screwed with a nut, which is locked into a groove provided in the connecting portion. When the locking rod is rotated, the plum blossom head and the nut compress the connecting portion, which in turn presses the bending seat firmly, preventing the bending seat from rotating and facilitating cleaning of the top of the stirring kettle.

[0014] Furthermore, in the aforementioned stirring tank cleaning device, the locking portion includes a locking male tube and a locking female tube. The locking male tube has a threaded portion that is screwed into the inner cavity of the locking female tube, which has an internal thread, an elastic groove, and a protrusion near one end of the threaded portion of the locking female tube.

[0015] As can be seen from the above technical solution, the present invention has the following beneficial effects: In the present invention, a flexible cleaning brush cleans the interior of the mixing kettle, and no static electricity or open flames are generated during the cleaning process, thereby ensuring the safety of the cleaning process and preventing the bristles of the cleaning brush from falling off, thereby avoiding contamination. The telescopic rod enables the flexible cleaning brush to clean the deep part of the mixing kettle, and the angle between the telescopic rod and the motor is adjusted by bending the joint to clean the top of the mixing kettle. At the same time, the compressed air ejected by the jet block blows away the powder sticking to the inner wall of the mixing kettle, thereby improving cleaning efficiency. The disc brush or strip brush cleans the top surface of the mixing kettle, solving the problem that traditional cleaning devices cannot clean the top surface of the mixing kettle.
