Description

Technical Field

[0001] This utility model relates to maintenance equipment for dust removal systems in industrial production, specifically to a cleaning tool for the interior of ceramic insulators in electrostatic precipitators. It is suitable for cleaning and maintaining the inner walls of ceramic insulators in industrial settings such as steel rolling mills, and belongs to the technical field of mechanical maintenance tools. Background Technology

[0002] In industrial production processes such as steel rolling mills, electrostatic precipitators (ESPs) are key equipment for controlling dust emissions. They achieve dust removal by applying high voltage to electric field plates, charging dust particles and attracting them. To ensure insulation between the electric field plates and the outer casing, porcelain insulators are typically used. However, during long-term operation, dust particles gradually accumulate on the inner wall of the insulators with the airflow, leading to a decrease in insulation between the outer casing and the connecting rods of the insulator plates. In severe cases, this can cause the ESP to malfunction.

[0003] Currently, the industry mostly uses homemade tools to clean the inside of porcelain insulators. Traditional tools typically consist of a cleaning cloth tied to an insulated rod via a rigid cable, which is then inserted through the insulator's inspection port to wipe the interior. However, these tools have the following significant drawbacks: Low cleaning efficiency: The cleaning cloth only contacts a point or a small area of ​​the inner wall of the ceramic bottle, and the coverage area of ​​a single cleaning is limited, requiring multiple repeated operations to complete the cleaning.

[0004] The cleaning cloth is prone to falling off: Because it is only simply tied and fixed, the cleaning cloth may fall off with a little force during the cleaning process. If it falls into the electric field, it may cause equipment failure or even safety hazards.

[0005] Incomplete cleaning: Due to the limitations of the tool structure, the cleaning cloth cannot fit tightly against the inner wall of the porcelain bottle, especially the curved parts, which are prone to forming cleaning dead corners, resulting in the residue of impurities and affecting the restoration of insulation performance.

[0006] Therefore, developing a cleaning tool for the interior of electrostatic precipitator ceramic insulators that can improve cleaning efficiency, ensure reliable fixing of the cleaning cloth, and achieve thorough cleaning has become an urgent technical problem to be solved in this field. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a cleaning tool with reasonable structure, convenient operation and good cleaning effect, which overcomes the defects of existing cleaning tools for the interior of ceramic insulators of electrostatic precipitators, such as low cleaning efficiency, easy detachment of cleaning cloth and incomplete cleaning.

[0008] The technical solution adopted by this utility model to solve the above problems is: a cleaning tool for the inside of an electrostatic precipitator ceramic insulator, comprising related components of the electrostatic precipitator equipment and a cleaning tool body, wherein: Related components of the electrostatic precipitator include: ceramic insulator plate connecting rod, ceramic insulator inspection port, ceramic insulator, electric field plate connecting rod, electric field shell, electric field plate and inner wall of ceramic insulator, and their positional relationship is consistent with that of existing electrostatic precipitators.

[0009] The main body of the cleaning tool includes the cleaning tool handle, the cleaning cloth fixing plate, the hinge connection, the cleaning tool handle support rod, the cleaning cloth fixing groove, and the hose clamp.

[0010] Connections and functions of each component: The cleaning tool handle is the part that the operator holds. It is made of insulating material (such as epoxy fiberglass pipe), with a length of 1.2-1.8m, adapted to the depth of the ceramic insulator, and has anti-slip texture on the surface to improve operational stability.

[0011] The cleaning tool handle support is fixedly connected to the end of the cleaning tool handle. The two are integrally formed with an included angle of 150°-170°, which can reduce hand obstruction during operation and facilitate observation of the cleaning status.

[0012] The cleaning cloth fixing plate is hinged to the cleaning tool handle support rod via a hinge connection. The hinge connection adopts a damping hinge with an angle adjustment range of 0°-90°: at 0°, it is parallel to the handle, which makes it easy to pass through the narrow porcelain bottle inspection port; at 90°, it is perpendicular to the handle, which allows the cleaning cloth to fit the inner wall of the porcelain bottle to the maximum extent.

[0013] The cleaning cloth fixing plate is shaped to fit the curved surface of the inner wall of the ceramic bottle (such as an arc), with a width no greater than the diameter of the ceramic bottle's access port, and a length of 1 / 3 to 1 / 2 of the axial length of the ceramic bottle. This ensures both passageability and increases the cleaning area per cycle. The end furthest from the hinge has a rounded transition structure to prevent scratching the inner wall of the ceramic bottle.

[0014] The cleaning cloth fixing groove consists of two symmetrical strip-shaped grooves on the surface of the cleaning cloth fixing plate, with a depth of 3-5mm and a width 1.2-1.5 times the diameter of the hose clamp. The hose clamp is embedded in the groove and tightened along the length of the fixing plate to firmly fix the cleaning cloth and prevent it from falling off.

[0015] The cleaning cloth is made of wear-resistant chemical fiber blended fabric, with the edges extending 5-10mm beyond the fixing plate to ensure a tight fit. The surface can be impregnated with insulating cleaning agent to enhance the cleaning effect while protecting the insulation performance of the porcelain insulator.

[0016] Operation process: Preparation: Place the cleaning cloth on the cleaning cloth fixing plate, making sure the edges extend beyond the fixing plate. Insert two hose clamps into the cleaning cloth fixing grooves respectively, and tighten the hose clamps to complete the fixation.

[0017] Insertion: Adjust the cleaning cloth fixing plate to be parallel (0°) to the handle of the cleaning tool, and slowly insert it into the porcelain bottle through the inspection port.

[0018] Cleaning: After reaching the cleaning position, adjust the hinge connection so that the cleaning cloth fixing plate is perpendicular to the handle (90°), ensuring that the cleaning cloth is in close contact with the inner wall of the porcelain bottle. Move the handle up and down to wipe and remove impurities.

[0019] Replace the cleaning cloth: When the cleaning cloth is dirty and needs to be replaced, slowly pull out the handle. The cleaning cloth fixing plate will automatically return to a parallel state along the inner wall of the porcelain bottle. After pulling it out, loosen the hose clamp and replace the cleaning cloth. Repeat the operation until it is clean.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. Significantly improved cleaning efficiency: The cleaning cloth fixing plate (9) increases the contact area between the cleaning cloth and the inner wall (7) of the porcelain bottle, expanding the coverage area of ​​a single cleaning by 3-5 times, reducing the number of operations and improving maintenance efficiency.

[0021] 2. Reliable cleaning cloth fixation: The cleaning cloth is double-fixed by the cleaning cloth fixing groove (12) and the hose clamp, which solves the problem of the cleaning cloth easily falling off in traditional tools and eliminates safety hazards.

[0022] 3. More thorough cleaning: The hinged design allows the cleaning cloth to fit snugly against the curved inner wall of the ceramic bottle, avoiding dead corners, and the handle operation applies even force to ensure that impurities are thoroughly removed and the insulation performance of the ceramic bottle is restored.

[0023] 4. Convenient and safe operation: The insulated handle design complies with safety regulations, the anti-slip texture improves operational stability, and the adjustable angle structure makes it easy for tools to enter and exit the maintenance port, reducing the difficulty of operation.

[0024] 5. Wide applicability: The cleaning cloth is replaceable and compatible with different impregnating cleaning agents, and can be used with various sizes of ceramic bottles, making it suitable for a wide range of applications. Attached Figure Description

However, these embodiments are merely descriptions of preferred implementations of this utility model and should not be construed as limiting the scope of this utility model in any way.

[0028] Example 1: In this embodiment, the cleaning tool handle 8 is made of 30mm diameter epoxy fiberglass pipe, 1.5m long, with anti-slip texture rolled on the surface; the cleaning tool handle support 11 is 100mm long and has an angle of 160° with the handle; the cleaning cloth fixing plate 9 is an arc-shaped steel plate, the curvature of which matches the inner wall of the 200mm diameter porcelain bottle, the width is 150mm (smaller than the 180mm diameter of the inspection port), and the length is 200mm (1 / 3 of the axial length of the porcelain bottle of 600mm); the cleaning cloth fixing groove 12 consists of two grooves 120mm long, 8mm wide, and 4mm deep, symmetrically distributed on both sides of the fixing plate; the hose clamp is a 6mm diameter stainless steel hose clamp; the cleaning cloth is a polyester-nylon blended fabric, 2mm thick, with the edge extending 8mm beyond the fixing plate.

[0029] During operation, follow the steps above to clean. A single up-and-down movement of the handle can cover an axial range of 200mm on the inner wall of the porcelain insulator, which is 4 times more efficient than traditional tools. The cleaning cloth does not fall off. After cleaning, the insulation resistance of the porcelain insulator is restored to more than 1000MΩ (50MΩ before cleaning).

[0030] Example 2: This embodiment is applicable to porcelain insulators with a diameter of 150mm. The cleaning cloth fixing plate 9 is 120mm wide and 150mm long (1 / 3 of the axial length of the porcelain insulator, which is 500mm). The other parameters are the same as in Embodiment 1. After cleaning, the insulation resistance recovers from 60MΩ to 1200MΩ, showing significant results.
