Description

Technical Field

[0001] This invention belongs to the field of mechanical cleaning technology, specifically relating to a wire brush with a self-cleaning function. Background Technology

[0002] In the nuclear power industry, a special type of radioactive waste is generated: metal plates contaminated with radioactive pollutants. These are large in quantity and difficult to handle. Typically, the radioactive contaminants are removed manually using scrapers, steel brushes, and other methods through a glove box. This process is time-consuming, labor-intensive, and poses a radiation hazard to operators. After using these tools, manual cleaning is still required, further increasing the risk of radiation exposure. Moreover, during the cleaning process with steel brushes and similar tools, contaminants can get into the gaps between the bristles, making cleaning difficult. If these contaminants are not removed, it not only causes problems for subsequent use but also increases the amount of radioactive waste, significantly complicating the overall decontamination effort. Summary of the Invention

[0003] The purpose of this invention is to provide a self-cleaning wire brush that can be used in conjunction with automated systems to brush away radioactive stains from the surface of metal plates. During operation, it generates an airflow at a certain velocity, which is used to clean the brush bristles. This solves the problem of previously requiring manual brush cleaning or simply treating the brush as radioactive waste, thus increasing the amount of waste to be disposed of.

[0004] To achieve the above objectives, the present invention provides a wire brush with a built-in cleaning function, comprising a motor system and a brush head system connected to the motor system. The brush head system is provided with a drainage hole and bristles. The motor system drives the bristles to rotate while providing a high-speed airflow, which cleans the bristles through the drainage hole.

[0005] Furthermore, the motor system includes a motor and a fan disposed at the end of the motor shaft. The fan generates the high-speed airflow as the shaft rotates. The motor and the shaft are an integral structure.

[0006] Furthermore, it also includes a large bushing connecting the motor system and the brush head system. The large bushing has a cylindrical structure and is disposed around the rotating shaft. The upper half of the large bushing is fixedly connected to the rotating shaft, and the lower half of the large bushing is fixedly connected to the brush head system, thereby realizing the connection between the motor system and the brush head system.

[0007] Furthermore, the large bushing has a small bushing inside, and the two are an integral structure; the small bushing is sleeved on the rotating shaft, and the small bushing and the rotating shaft are fixedly connected by a pin and key to transmit torque, thereby realizing the fixed connection between the large bushing and the rotating shaft.

[0008] Furthermore, the large bushing, the rotating shaft, and the small bushing are coaxial.

[0009] Furthermore, a gap is left between the large bushing and the motor to allow gas to flow in and generate the high-speed airflow.

[0010] Furthermore, the brush head system includes a fixing sleeve and the brush bristles. The fixing sleeve has a cylindrical structure. The top end of the fixing sleeve is fixedly disposed inside the lower half of the large bushing. The roots of the brush bristles are disposed inside the fixing sleeve, and the heads of the brush bristles extend beyond the bottom opening of the fixing sleeve.

[0011] Furthermore, the fixing sleeve is coaxial with the large bushing.

[0012] Furthermore, the fixed sleeve and the large bushing are fixedly connected by threads.

[0013] Furthermore, the top of the fixing sleeve is provided with a drainage layer, which is disc-shaped, and the edge of the drainage layer is sealed to the cylindrical body of the fixing sleeve; the drainage hole is provided on the drainage layer; and the root of the bristles is provided on the lower surface of the drainage layer.

[0014] Furthermore, a gap is left between the upper surface of the drainage layer and the fan and the shaft.

[0015] further,

[0016] The drainage hole includes a first drainage hole, a second drainage hole, and a third drainage hole;

[0017] The first drainage hole is a plurality of holes, which are evenly arranged around the center of the drainage layer. The first drainage hole penetrates the drainage layer. The high-speed airflow blows the bristles from the root to the head through the first drainage hole, thus achieving longitudinal blowing.

[0018] The second drainage hole is a single hole, located at the center of the drainage layer and penetrating the drainage layer;

[0019] A drainage tube is provided on the lower surface of the drainage layer. The drainage tube has a hollow structure and is vertically and sealed to the center of the drainage layer. The top end of the drainage tube has an opening that communicates with the bottom opening of the second drainage hole. The bottom end of the drainage tube is sealed. Several third drainage holes are evenly arranged on the side wall of the drainage tube. The high-speed airflow enters the drainage tube through the second drainage hole and flows out through the third drainage hole to sweep the bristles laterally.

[0020] The high-speed airflow flows out perpendicularly to each other through the first and third drainage holes.

[0021] Furthermore, the second drainage hole is a tapered hole, with the diameter of the top opening being larger than the diameter of the bottom opening.

[0022] Furthermore, the bottom end of the drainage tube is located within the bottom opening of the fixing sleeve.

[0023] Furthermore, the large bushing, the fixed sleeve, the small bushing, the drainage layer, and the drainage tube are all made of steel.

[0024] Furthermore, the bristles are made of hard steel wire and are fixed to the lower surface of the drainage layer by welding.

[0025] Furthermore, the fan is made of plastic and can be fixedly connected to the shaft by heating.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention addresses the problem of increased radiation risk to personnel due to the need for manual cleaning of wire brushes during the cleaning of metal surfaces contaminated with radioactive stains. It provides a self-cleaning wire brush. Through a fan 5 and a drainage hole installed on the shaft 6 of the motor 1, airflow can clean the brush bristles 4. Part of the airflow blows from the center outwards through the second drainage hole 8 (conical drainage hole), while another part blows from the root of the bristles 4 to the head through the first drainage hole 7 (root drainage hole), achieving automatic cleaning of the bristles 4. During this process, no operator intervention is required. It can clean the bristles 4 while simultaneously performing brushing and milling operations on the contaminated metal surface, effectively improving cleaning efficiency and solving problems such as cumbersome operation and high radiation risk.

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] This invention provides a wire brush with a built-in cleaning function (see...) Figure 1 , 2 6, 7), which includes a motor system and a brush head system connected to the motor system. The brush head system is provided with a drainage hole and brush bristles 4. The motor system drives the brush bristles 4 to rotate while providing high-speed airflow. The high-speed airflow cleans the brush bristles 4 through the drainage hole (achieving self-cleaning function).

[0040] The motor system includes a motor 1 and a fan 5 located at the end of the shaft 6 of the motor 1. The fan 5 generates high-speed airflow as the shaft 6 rotates. The motor 1 and the shaft 6 are an integral structure (see...). Figure 3 ).

[0041] It also includes a large bushing 2 that connects the motor system and the brush head system. The large bushing 2 has a cylindrical structure and is located around the rotating shaft 6. The upper half of the large bushing 2 is fixedly connected to the rotating shaft 6, and the lower half of the large bushing 2 is fixedly connected to the brush head system, thus realizing the connection between the motor system and the brush head system. The large bushing 2 can transmit a large torque, has a reliable connection, and provides good coaxiality and guidance between the connected parts.

[0042] The large bushing 2 has a small bushing 10 inside, and the two are integrated. The small bushing 10 is fitted onto the rotating shaft 6, and the small bushing 10 and the rotating shaft 6 are fixedly connected by a pin 9 to transmit torque, thereby achieving a fixed connection between the large bushing 2 and the rotating shaft 6. The rotating shaft 6 of the motor 1 is inserted into the small bushing 10 and fixed with the pin 9, thus achieving a fixed connection between the large bushing 2 and the motor system. The pin 9 can transmit a large torque, the connection is reliable, and the coaxiality and guiding properties between the connected parts are good.

[0043] Large bushing 2, rotating shaft 6 and small bushing 10 are coaxial.

[0044] A gap is left between the large bushing 2 and the motor 1 to allow gas to flow in and generate a high-speed airflow.

[0045] The brush head system includes a retaining sleeve 3 and bristles 4 (see...) Figure 4 , 5 The fixing sleeve 3 is a cylindrical structure. The top of the fixing sleeve 3 is fixedly installed inside the lower half of the large shaft sleeve 2. The root of the bristles 4 is installed inside the fixing sleeve 3, and the head of the bristles 4 extends to the bottom opening of the fixing sleeve 3.

[0046] The fixed sleeve 3 is coaxial with the large shaft sleeve 2.

[0047] The fixed sleeve 3 and the large shaft sleeve 2 are fixedly connected by threads, so as to achieve a fixed connection between the large shaft sleeve 2 and the brush head system.

[0048] The top of the fixed sleeve 3 is provided with a drainage layer 11 (see Figure 6 , 7 (8, 9) The drainage layer 11 is disc-shaped, and the edge of the drainage layer 11 is sealed to the cylinder of the fixing sleeve 3; the drainage hole is set on the drainage layer 11; the root of the bristles 4 is set on the lower surface of the drainage layer 11.

[0049] A gap is left between the upper surface of the air intake layer 11 and the fan 5 and the shaft 6.

[0050] The drainage holes include a first drainage hole 7, a second drainage hole 8, and a third drainage hole 13;

[0051] There are several first drainage holes 7, which are evenly arranged around the center of the drainage layer 11. The first drainage holes 7 penetrate the drainage layer 11. The high-speed airflow blows the bristles 4 from the root to the head through the first drainage holes 7, thus achieving longitudinal blowing.

[0052] The second drainage hole 8 is one, located at the center of the drainage layer 11, and penetrates the drainage layer 11;

[0053] A drainage tube 12 is provided on the lower surface of the drainage layer 11. The drainage tube 12 has a hollow structure and is vertically and sealed to the center of the drainage layer 11. The top end of the drainage tube 12 has an opening that communicates with the bottom opening of the second drainage hole 8. The bottom end of the drainage tube 12 has a sealed structure. Several third drainage holes 13 are evenly arranged on the side wall of the drainage tube 12. The high-speed airflow enters the drainage tube 12 through the second drainage hole 8 and flows out through the third drainage hole 13 to sweep the bristles 4 laterally.

[0054] The high-speed airflow flows out perpendicularly to each other through the first drain hole 7 and the third drain hole 13.

[0055] The second drainage hole 8 is a tapered hole, with the diameter of the top opening being larger than the diameter of the bottom opening.

[0056] The bottom end of the drainage tube 12 is located inside the bottom opening of the fixing sleeve 3.

[0057] The large bushing 2, the fixed bushing 3, the small bushing 10, the drainage layer 11, and the drainage tube 12 are all made of steel.

[0058] The bristles 4 are made of hard steel wire and are fixed to the lower surface of the drainage layer 11 by welding.

[0059] The fan 5 is made of plastic and can be fixedly connected to the shaft 6 by means of heating.

[0060] When the present invention is powered on, the shaft 6 of the motor 1 rotates at high speed, simultaneously driving the fan 5 and the fixing sleeve 3 to rotate at high speed. This causes the bristles 4 to rotate at high speed, and the heads of the bristles 4 contact the contaminated metal surface, generating friction and milling action to clean the metal surface. However, radioactive contaminants, metal debris, etc., may enter the gaps between the bristles 4, contaminating them. Simultaneously, the fan 5, following the shaft 6, also rotates at high speed, generating a high-speed airflow. Due to the curvature of the fan blades, the airflow flows from the motor 1 towards the bristles 4. The generated airflow is divided into two parts: one part passes through the second drainage hole 8 (conical drainage hole) and the third drainage hole 13, blowing from the center outwards in a circumferential direction, producing a lateral blowing effect on the bristles 4; the other part passes through the first drainage hole 7 (root drainage hole), blowing from the root of the bristles 4 towards the head, producing a vertical blowing effect on the bristles 4. By blowing horizontally and vertically, dirt and other contaminants between the bristles 4 can be cleaned, achieving the self-cleaning function of the bristles 4 and extending the service life of the wire brush. The entire process requires no manual intervention, which not only reduces the problem of generating a large amount of radioactive waste due to discarded wire brushes, but also effectively reduces the risk of radiation exposure to personnel.

[0061] The device described in this invention is not limited to the embodiments described in the specific implementation. Other implementation methods derived by those skilled in the art based on the technical solution of this invention also fall within the scope of technical innovation of this invention.
