Description

Technical Field

[0001] This utility model relates to the field of pipeline slag removal technology, specifically to an electrostatic precipitator polygonal pipeline slag removal tool. Background Technology

[0002] Electrostatic precipitators are key equipment for controlling pollutant emissions in industrial production. However, during long-term operation, dust, acid sludge, and other sludge can easily accumulate on the inner wall of the pipes. If not cleaned in time, this can lead to a reduction in the pipe cross-section, an increase in airflow resistance, and in severe cases, even pipe blockage, significantly reducing the efficiency of electrostatic precipitators.

[0003] Existing slag removal tools are mostly brush or scraper structures adapted to circular pipes. When applied to polygonal pipes, the circular cross-section of the slag removal tool cannot fully fit the inner wall of the polygonal pipe, easily forming a large number of slag removal dead corners at the pipe edges and corners. The accumulated slag is difficult to remove completely, resulting in low slag removal efficiency. It often requires multiple operations to achieve a certain effect, and the slag removal operation time is long, thus affecting the continuity of production. Utility Model Content

[0004] The purpose of this utility model is to provide a slag removal tool for polygonal pipes in electrostatic precipitators. This tool can achieve slag removal from polygonal pipes without dead angles, while improving the slag removal effect, shortening the slag removal operation time, and reducing the impact on production continuity.

[0005] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: an electrostatic precipitator polygonal pipe slag removal tool, comprising two slag removal bodies; A connecting structure is provided between the two slag-cleaning bodies; A traction rope is provided on one side away from each other between the two slag-cleaning bodies; The slag removal body includes a flexible slag removal component, which is inserted into a polygonal pipe and connected to the connecting structure. Two pressure irons are coaxially and symmetrically arranged on both sides of the flexible slag removal component, and the traction rope is coaxially provided on one of the pressure irons.

[0006] In some embodiments, the connection structure includes four connecting rods arranged in a matrix, and the connecting rods pass through the flexible slag removal component and the pressure iron; Multiple locking nuts are screwed into the connecting rod and pressed against the side of the pressure iron away from the flexible slag removal component.

[0007] In some embodiments, the flexible slag removal component is a polygonal rubber sheet.

[0008] In some embodiments, the pressure iron is polygonal, and the side length of the pressure iron is smaller than the side length of the flexible slag removal component.

[0009] In some embodiments, a hard slag removal structure is also included, the hard slag removal structure being disposed on the side of the pressure iron away from the flexible slag removal member.

[0010] In some embodiments, the hard slag removal structure includes multiple support plates, which are arranged around the pressure iron. A slag-removing plate is disposed between two adjacent support plates.

[0011] In some embodiments, the hard slag removal structure further includes multiple connecting plates, which are equally spaced between the slag removal plate and the pressure iron.

[0012] In some embodiments, the slag removal plate is inclined, and the end of the slag removal plate away from the pressure iron is provided with serrations.

[0013] In summary, this utility model has the following beneficial effects: This utility model's flexible slag removal component, when plugged into a polygonal pipe, can completely conform to the inner wall of the polygonal pipe, effectively eliminating slag removal dead angles and achieving thorough slag removal. This reduces the risk of pollutant leakage caused by slag residue, meets environmental protection requirements, and lowers the environmental governance costs and risks for enterprises. At the same time, a single slag removal operation can cover most of the pipeline area, improving slag removal efficiency, thereby reducing the need for repeated operations, shortening the time required for slag removal, improving production continuity, and reducing production interruption losses caused by slag removal.

[0014] This invention features a hard slag-removing structure on the pressure iron to break up stubborn slag, and together with the flexible slag-removing component to remove loose slag, it forms a complementary mechanism of breaking down first and then cleaning, ensuring thorough slag removal while avoiding damage to the pipeline.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] refer to Figure 1-5 An electrostatic precipitator polygonal pipe cleaning tool is disclosed, comprising two cleaning bodies 1, a connecting structure 2, and a traction rope. The components work together precisely to achieve efficient cleaning of the polygonal pipe. The cleaning body 1, the core execution component, is symmetrically distributed on both sides of the connecting structure 2, allowing for simultaneous bidirectional scraping of the pipe's inner wall. This effectively expands the cleaning coverage area per pass, improves cleaning efficiency, and reduces the number of tool reciprocating movements. The connecting structure 2, located between the two cleaning bodies 1, serves as a connection and fixation mechanism, ensuring synchronized movement of the two cleaning bodies 1 during cleaning. This prevents tool deviation due to uneven force on one side, ensuring a stable cleaning trajectory. The traction rope, which can be made of nylon or steel wire, is fixed to the opposite side of the two cleaning bodies 1. A fixing post can be installed on the cleaning body 1, and the traction rope is connected to the fixing post for a fixed connection. By pulling the traction rope at both ends, the operator can drive the tool to move smoothly back and forth within the pipe, completing the cleaning of the entire pipe without frequent tool disassembly, thus simplifying the operation process.

[0018] The slag removal body 1 includes a flexible slag removal component 11 and two pressure irons 12. The flexible slag removal component 11 matches the shape of the inner wall of the polygonal pipe and can be inserted into the pipe to fit tightly against the inner wall. At the same time, the flexible slag removal component 11 is fixedly connected to the connecting structure 2 to ensure that it does not detach from the main frame during the slag removal process. It removes loose slag from the inner wall and corners of the pipe through its own flexibility, avoiding scratching the anti-corrosion layer of the inner wall of the pipe. The two pressure irons 12 are coaxially and symmetrically assembled on both sides of the flexible slag removal component 11. The connecting structure 2 provides continuous pressure to the flexible slag removal component 11 to prevent the flexible slag removal component 11 from tilting due to airflow impact or tool movement during the slag removal process. In addition, a traction rope is coaxially fixed on one of the pressure irons 12 to ensure that the traction force can be evenly transmitted to the slag removal body 1 and to prevent the tool from shifting under force.

[0019] In some embodiments, the connecting structure 2 includes four connecting rods 21 and multiple locking nuts 22. The connecting rods 21 can be made of high-strength metal materials such as stainless steel. The four connecting rods 21 can be distributed in a 2×2 matrix, with the matrix spacing adapted to the side length of the pressure iron 12. The connecting rods 21 pass through the preset mounting holes of the flexible slag cleaning component 11 and the pressure irons 12 on both sides. The matrix distribution can evenly distribute the force generated during the slag cleaning process, avoiding excessive force on a single connecting rod 21 and causing deformation, thus ensuring the overall structural stability of the slag cleaning body 1. The multiple locking nuts 22 are matched to the specifications of the connecting rods 21 and can be assembled at both ends of the connecting rods 21 by screw connection. The locking nuts 22 are pressed against the side of the pressure iron 12 away from the flexible slag cleaning component 11. By tightening the locking nuts 22, the flexible slag cleaning component 11 and the pressure iron 12 can be tightly fixed as a whole, preventing the components from loosening during the slag cleaning process. When the flexible slag cleaning component 11 needs to be replaced later, it can be disassembled simply by loosening the locking nuts 22, making the operation convenient.

[0020] In some embodiments, to balance the fit and wear resistance of the flexible slag cleaning component 11, the flexible slag cleaning component 11 can be made of polygonal rubber sheet, which can be nitrile rubber or neoprene rubber with a Shore hardness of 60-70. The rubber material has good elastic deformation capability, which can adapt to the slight dimensional errors of the inner wall of the pipe, ensuring complete fit with the inner wall of the polygonal pipe and eliminating dead angles for slag cleaning; at the same time, the wear resistance of the rubber material can meet the needs of long-term slag cleaning operations, extend the service life of the flexible slag cleaning component 11, and reduce the maintenance frequency.

[0021] In some embodiments, the pressure iron 12 can be designed as a polygonal structure that matches the flexible slag-cleaning component 11, and the side length of the pressure iron 12 is smaller than the side length of the flexible slag-cleaning component 11, with the difference controlled within 5-8 mm. This design keeps the deformable portion of the flexible slag-cleaning component 11 within a reasonable range, which can both prevent the corner slag from being unable to be removed due to obstruction by the pressure iron 12, thus improving the thoroughness of slag removal, and prevent the flexible slag-cleaning component 11 from deforming too much, resulting in excessive gaps between the edge of the flexible slag-cleaning component 11 and the inner wall of the pipe, thereby affecting the slag removal effect.

[0022] In some embodiments, a hard slag removal structure 3 is also included. The hard slag removal structure 3 is located on the side of the pressure iron 12 away from the flexible slag removal component 11. It can clean stubborn slag such as solidified acid sludge and hardened dust attached to the inner wall of the pipeline. It forms a composite slag removal function with the flexible slag removal component 11, improves the slag removal effect, and protects the flexible slag removal component 11, extending the service life of the flexible slag removal component 11.

[0023] In some embodiments, the hard slag removal structure 3 includes multiple support plates 31 and a slag removal plate 32. The support plates 31 can be made of steel plates with a thickness of 4-6mm, and their number is consistent with the number of sides of the polygonal pipe. The multiple support plates 31 are arranged around the pressure iron 12 and can be fixed by welding. They can be fixed at the connection of the two edges of the pressure iron 12. The spacing between two adjacent support plates 31 matches the side length of the inner wall of the pipe, providing stable support for the slag removal plate 32 and preventing the slag removal plate 32 from bending when breaking up stubborn slag. The slag removal plate 32 can be made of high-strength manganese steel plate with a thickness of 3-5mm and fixed between two adjacent support plates 31, directly contacting the stubborn slag on the inner wall of the pipe. The high strength of the manganese steel material can effectively break up solidified slag, and in conjunction with the flexible slag removal component 11, it can remove residual debris, improving the slag removal efficiency.

[0024] In some embodiments, the hard slag removal structure 3 further includes multiple connecting plates 33. The connecting plates 33 can be made of steel plates with a thickness of 3-4 mm. Two to three connecting plates are assembled at equal intervals between each slag removal plate 32 and the pressure iron 12. One end of the connecting plates 33 is welded and fixed to the slag removal plate 32, and the other end is welded and fixed to the pressure iron 12. The connecting plates 33 can enhance the connection strength between the slag removal plate 32 and the pressure iron 12, disperse the impact force borne by the slag removal plate 32 during operation, prevent the root of the slag removal plate 32 from breaking due to concentrated force, and extend the service life of the hard slag removal structure 3.

[0025] In some embodiments, the slag-cleaning plate 32 can be inclined, and the inclination angle α between the end face connected to the pressure iron 12 and the slag-cleaning plate 32 can be 15-20°. When the tool moves inside the pipe, the inclined slag-cleaning plate 32 can generate cutting force on stubborn slag, making it easier to cut into the slag and reduce the breaking resistance. The end of the slag-cleaning plate 32 away from the pressure iron 12 is provided with serrations, which can quickly break up stubborn slag and prevent the slag-cleaning plate 32 from slipping on the slag, thus improving the efficiency of hard slag breaking. The height of the slag-cleaning plate 32 is less than the height of the flexible slag-cleaning component 11, which can prevent the slag-cleaning plate 32 from directly contacting the inner wall of the pipe and damaging the inner wall of the pipe.

[0026] The specific working principle is as follows: Before carrying out slag removal operations, tools must be pre-installed according to the specifications (side length, number of sides) of the polygonal pipe to be cleaned to ensure the compatibility of each component.

[0027] Place the flexible slag removal component 11, which matches the side length of the pipe, between the two pressure irons 12, aligning the mounting holes of the flexible slag removal component 11 and the pressure irons 12. Then, insert four connecting rods 21 through the mounting holes, screw in locking nuts 22 at both ends of the connecting rods 21 and tighten them. Use the clamping force of the locking nuts 22 to firmly fix the pressure irons 12 and the flexible slag removal component 11, forming a single slag removal body 1. Connect the two slag removal bodies 1 symmetrically through the connecting structure 2. Finally, fix the traction rope coaxially on the pressure irons 12 that are far apart from each other on the two slag removal bodies 1, completing the overall pre-assembly of the tool.

[0028] After pre-installation, operators use the traction ropes at both ends to guide the tool into the slag-cleaning area of ​​the pipeline. One or two operators hold the traction ropes at the feed end of the pipeline, aligning the slag-cleaning body 1 of the tool with the pipeline inlet. Because the flexible slag-cleaning component 11 has a polygonal structure that matches the pipeline and has elastic deformation capability, it can easily be inserted into the pipeline and smoothly enter the pipeline. Operators slowly pull the traction rope at the discharge end of the pipeline, while operators at the feed end assist in pushing, so that the tool moves smoothly along the pipeline axis. Operators alternately pull the traction ropes at both ends to drive the tool to move back and forth inside the pipeline.

[0029] During movement, the flexible cleaning component 11 fits tightly against the inner wall of the pipe, and its elastic deformation capability can adapt to the slight dimensional errors of the inner wall of the pipe, ensuring no dead corners are covered. For loose slag (such as dust and soft acid sludge) on the inner wall and corners of the pipe, the flexible cleaning component 11 peels it off from the inner wall of the pipe through its own scraping action; when encountering stubborn slag such as solidified acid sludge and hardened dust, the serrated end of the cleaning plate 32 first cuts into the slag, and the cutting force generated by the inclined angle breaks the slag. Then the flexible cleaning component 11 follows up to remove the remaining debris, realizing continuous operation and ensuring that there is no slag residue on the inner wall of the pipe.

[0030] After the slag removal operation is completed, the operator pulls the traction rope at one end of the pipeline to slowly pull the tool out of the pipeline. After retrieval, check the condition of each component. If the flexible slag removal component 11 shows obvious wear or damage, loosen the locking nut 22 of the connecting structure 2, disassemble the old flexible slag removal component 11, replace it with a new component, and then tighten the locking nut 22 to complete the maintenance.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
