Description

Technical Field

[0001] The utility model relates to the technical field of filter screen cleaning, in particular to a filter screen cleaning device for a sintering furnace. Background Art

[0002] A sintering furnace is a device used in the magnet processing process. Magnet processing usually includes the steps of mixing, molding and sintering of magnetic powder. Sintering is to heat the magnetic powder under high temperature conditions to make the particles combine to form a solid magnetic material. The sintering furnace plays an important role in the magnet processing process. Through the sintering process, the magnet material can achieve a higher density and strength, improve its magnetic properties and wear resistance. The design and operating parameters of the sintering furnace have an important influence on the performance of the final magnet material. Therefore, the selection and use of a sintering furnace requires experience and expertise.

[0003] In the sintering furnace, a filter is usually installed. The filter is mainly used to filter impurities and particulate matter in magnetic powder or other raw materials to ensure the quality of the final magnet. The filter is generally installed on the feed port or feed pipe of the sintering furnace to filter the raw materials entering the sintering furnace. This can prevent impurities from entering the sintering furnace and affecting the performance and quality of the magnet. After long-term use, the filter may be attached with too many impurities, affecting the filtering performance. At the same time, due to the adsorption of magnetic powder to a certain extent, some magnetic powder may be adsorbed on the filter, which will affect the filtering effect of the filter. Utility Model Content

[0004] The utility model aims to provide a filter cleaning device for a sintering furnace, which is used to clean impurities and adsorbed magnetic powder on the filter, thereby restoring the filtering effect of the filter and improving the quality of the magnet material coming out of the sintering furnace.

[0005] In order to solve the above technical problems, the utility model adopts the following solutions:

[0006] A filter cleaning device for a sintering furnace comprises a cleaning box with an opening at the upper end, a supporting leg is arranged at the bottom of the cleaning box, a clamping device for clamping two ends of the filter is rotatably arranged on two opposite inner walls of the cleaning box, a driving device for driving a clamping device to rotate is arranged on the outer wall of the cleaning box, a convex spray box is arranged on an inner side wall of the cleaning box, a strip-shaped nozzle is arranged on the end face of the spray box opposite to the filter, the spray box is connected to a liquid storage tank pipeline outside the cleaning box, cleaning liquid is stored in the liquid storage tank, a booster pump is arranged between the spray box and the liquid storage tank, and the nozzle sprays a continuous cleaning surface adapted to the length of the filter under the action of the booster pump, and the continuous cleaning surface is located in the opposite direction of the tangent of the filter to form a reverse scraping and cleaning of the filter.

[0007] Due to the adoption of the above technical solution, the design of the cleaning box provides a stable cleaning environment for the filter. The supporting legs not only stabilize the cleaning box, but also enable the entire device to be placed stably on the ground.

The surface of the filter screen is covered to achieve cleaning without dead angles. In addition, the setting of the booster pump further enhances the cleaning effect. Under the action of the booster pump, the cleaning liquid can be sprayed out from the nozzle at a higher pressure and speed, forming a strong impact on the filter screen. When the driving device drives the filter screen to rotate, the continuous cleaning surface is cleaned by reverse scraping, forming a cleaning method similar to a scraper attached to the surface of the filter screen, which can effectively remove dirt and impurities on the filter screen. At the same time, since the continuous cleaning surface is composed of cleaning liquid, it can also clean impurities in the mesh of the filter screen. Therefore, the filter cleaning device of the sintering furnace has the advantages of simple structure, easy operation and high cleaning efficiency. It not only improves the cleaning quality of the filter screen, but also extends the service life of the filter screen, providing a strong guarantee for the normal operation of the sintering furnace.

[0027] Example

[0028] A device for cleaning a filter screen 10 of a sintering furnace comprises a cleaning box 1 with an opening at the upper end, a supporting leg 2 being arranged at the bottom of the cleaning box 1, clamping devices for clamping the two ends of the filter screen 10 being rotatably arranged on two opposite inner walls of the cleaning box 1, a driving device for driving one of the clamping devices to rotate being arranged on the outer wall of the cleaning box 1, a convex spray box 15 being arranged on an inner side wall of the cleaning box 1, a strip-shaped nozzle 16 being arranged on the end face of the spray box 15 opposite to the filter screen 10, the spray box 15 being connected to a liquid storage tank 14 outside the cleaning box 1 by a pipeline, the liquid storage tank 14 storing cleaning liquid, a booster pump 13 being arranged between the spray box 15 and the liquid storage tank 14, the nozzle 16 spraying a continuous cleaning surface 21 adapted to the length of the filter screen 10 under the action of the booster pump 13, the continuous cleaning surface 21 being located in the opposite direction of the tangent of the filter screen 10 to form a reverse scraping and cleaning of the filter screen 10.

[0029] In this embodiment, Figure 1 As shown, the design of the cleaning box 1 provides a stable cleaning environment for the filter 10. The supporting legs 2 not only stabilize the cleaning box 1, but also enable the entire device to be placed stably on the ground. The clamping device is rotatably arranged on the two opposite inner walls of the cleaning box 1, so that the two ends of the filter 10 can be firmly clamped. In this way, during the cleaning process, the filter 10 can remain stable and will not shake or shift due to the impact of the cleaning liquid. The function of the driving device is to provide power for the clamping device. Through the driving device, the rotation of the clamping device can be conveniently controlled, thereby realizing the rapid clamping and loosening of the filter 10. Figure 4 As shown, the spray box 15 adopts a convex structure, so that the nozzle 16 can be directly aimed at the filter 10, and the strip-shaped nozzle 16 design can ensure that the cleaning liquid forms a continuous cleaning surface 21 that is adapted to the length of the filter 10. In this way, the cleaning liquid can fully cover the surface of the filter 10 to achieve cleaning without dead angles. In addition, the setting of the booster pump 13 further enhances the cleaning effect. Under the action of the booster pump 13, the cleaning liquid can be sprayed from the nozzle 16 at a higher pressure and speed, forming a strong impact on the filter 10. When the driving device drives the filter 10 to rotate, as shown in FIG. Figure 2 As shown, the continuous cleaning surface 21 forms a reverse scraping cleaning method, which is similar to the cleaning method in which a scraper is attached to the surface of the filter 10. In this way, when the filter 10 rotates, the continuous cleaning surface 21 can effectively remove dirt and impurities on the filter 10. The filter 10 cleaning device of the sintering furnace has the advantages of simple structure, convenient operation, and high cleaning efficiency. It not only improves the cleaning quality of the filter 10, but also extends the service life of the filter 10, providing a strong guarantee for the normal operation of the sintering furnace.

[0030] Furthermore, the connecting end of the spray box 15 and the booster pump 13 is hinged on the inner wall of the cleaning box 1, and a through hole is provided on the inner wall of the cleaning box 1 to allow the pipeline to pass through. A hydraulic telescopic rod 17 is provided between the spray box 15 and the inner wall of the cleaning box 1, and one end of the hydraulic telescopic rod 17 is hinged to the top wall of the spray box 15, and the other end is hinged to the inner wall of the cleaning box 1.

[0031] Specifically, Figure 2 As shown, the design that the connecting end of the spray box 15 and the booster pump 13 is hinged on the inner wall of the cleaning box 1 allows the spray box 15 to swing or adjust the angle within a certain range to adapt to filter screens 10 of different sizes or shapes. The through hole arranged on the inner wall of the cleaning box 1 allows the pipeline to pass through, which provides convenience for the connection between the spray box 15 and the booster pump 13, and also ensures the cleanliness and easy maintenance of the interior of the cleaning box 1. The setting of the hydraulic telescopic rod 17 further enhances the flexibility of the spray box 15. One end of the hydraulic telescopic rod 17 is hinged to the top wall of the spray box 15, and the other end is hinged to the inner wall of the cleaning box 1. By controlling the extension and contraction of the hydraulic telescopic rod 17, the distance and angle between the spray box 15 and the filter screen 10 can be easily adjusted. In this way, no matter how the size of the filter screen 10 changes, the optimal cleaning distance and angle between the nozzle 16 and the filter screen 10 can be ensured by adjusting the hydraulic telescopic rod 17, so that the continuous cleaning surface 21 formed by the injection can quickly clean the impurities on the filter screen 10.

[0032] Furthermore, a plurality of guide plates 18 are distributed inside the spray box 15 , and the guide plates 18 guide the cleaning liquid to the area between the two ends of the spray box 15 .

[0033] Specifically, Figure 4 As shown, a plurality of guide plates 18 are distributed inside the spray box 15. The function of the guide plates 18 is to guide the cleaning liquid entering the spray box 15 so that it can be evenly distributed inside the spray box 15 and mainly flow to the area between the two ends of the spray box 15. This design ensures that the cleaning liquid can form a uniform and powerful spray force at the nozzle 16, thereby achieving the cleaning of the filter 10. Secondly, the design of the guide plates 18 helps to reduce the flow resistance of the cleaning liquid in the spray box 15, and improve the flow rate and impact force of the cleaning liquid. In this way, the cleaning liquid can more effectively flush the dirt and impurities on the filter 10, thereby improving the cleaning effect. The guide plates 18 on both sides are arc-shaped, and the middle guide plate 18 is a straight plate. The side of the guide plate 18 is coated with a polytetrafluoroethylene layer to enhance the guide speed.

[0034] Furthermore, the nozzle 16 is a rubber nozzle 16, the cross section of the nozzle 16 is conical, the injection port 20 of the nozzle 16 is strip-shaped, and the width of the injection port 20 is 1-3 mm.

[0035] Specifically, Figure 2 and Figure 3 As shown, in this cleaning device, the nozzle 16 is made of rubber material. The rubber nozzle 16 has excellent elasticity and wear resistance, which enables the nozzle 16 to maintain a good shape and spray performance during use and is not easy to deform or damage. In addition, the rubber material also has a certain corrosion resistance and can resist the erosion of chemical substances that may exist in the cleaning liquid, thereby extending the service life of the nozzle 16. Secondly, the cross-section of the nozzle 16 is designed in a conical shape, which helps to form a high-pressure jet flow. When the cleaning liquid passes through the nozzle 16, the conical structure can compress the liquid at the outlet, thereby increasing the pressure and speed of the jet. The high-pressure jet flow can more effectively flush the dirt and impurities on the filter 10 and improve the cleaning effect. In addition, the jet port 20 of the nozzle 16 is designed in a strip shape, and the width of the jet port 20 is controlled between 1-3mm. This design enables the cleaning liquid to form a slender jet flow, increasing the coverage area and impact force of the jet. At the same time, the moderate width of the jet port 20 can ensure that the cleaning liquid maintains a stable pressure and flow during the jet process to avoid waste and excessive flushing.

[0036] Furthermore, the clamping device includes a support plate 9 and a first locking plate 11 and a second locking plate 6. The first locking plate 11 and the second locking plate 6 are semicircular. The support plate 9 is located on the inner side of the filter screen 10. The first locking plate 11 and the second locking plate 6 are distributed above and below. When the first locking plate 11 and the second locking plate 6 are closed, the two ends of the filter screen 10 are clamped. A rotating shaft 12 is provided on the outer side of the support plate 9. The rotating shaft 12 is rotatably connected to the inner wall of the cleaning box 1, and one of the rotating shafts 12 extends to the outside of the cleaning box 1 and is connected to the output end of the driving device.

[0037] Furthermore, both ends of the first locking plate 11 and the second locking plate 6 are provided with connecting plates 19, and threaded through holes are opened on the connecting plates 19. After the first locking plate 11 and the second locking plate 6 are closed, they are connected by bolts passing through the threaded through holes.

[0038] Furthermore, the driving device is a driving motor 8 , and a fixing plate 7 for supporting the driving motor 8 is fixed on the outer wall of the cleaning box 1 .

[0039] Specifically, Figure 1 and Figure 5As shown, the clamping device is composed of a support plate 9, a first locking plate 11 and a second locking plate 6, forming a clamping device that can firmly clamp the filter screen 10. The first locking plate 11 and the second locking plate 6 are semicircular. When they are closed, they can form a complete circle, thereby tightly wrapping the two ends of the filter screen 10. The support plate 9 is located on the inner side of the filter screen 10 to play a supporting and stabilizing role. This design not only ensures the stability of the filter screen 10 during the cleaning process, but also enables the device to adapt to filter screens 10 of different sizes. The operation of the clamping device is also very convenient. A rotating shaft 12 is provided on the outer side of the support plate 9. These rotating shafts 12 are rotatably connected to the inner side wall of the cleaning box 1, so that the clamping device can be easily opened and closed. One of the rotating shafts 12 also extends to the outside of the cleaning box 1 and is connected to the output end of the driving device. , through the control of the driving device, the automatic opening and closing of the clamping device can be realized, which greatly improves the convenience of operation. In addition, both ends of the first locking plate 11 and the second locking plate 6 are provided with connecting plates 19, and threaded through holes are opened on the connecting plates 19. When the first locking plate 11 and the second locking plate 6 are closed, they can be connected by passing bolts through the threaded through holes, thereby clamping the two ends of the filter screen 10. This design not only enhances the stability of the clamping device, but also makes the device easy to disassemble and repair when necessary. The driving device adopts a driving motor 8, and a fixing plate 7 for supporting the driving motor 8 is fixed on the outer wall of the cleaning box 1, which ensures the stability and safety of the driving motor 8. Through the control of the driving motor 8, the opening and closing speed and strength of the clamping device can be accurately controlled, thereby achieving efficient cleaning of the filter screen 10.

[0040] Furthermore, the bottom of the cleaning box 1 is a concave spherical surface, and a mounting cavity is provided on the bottom of the concave spherical surface. A strong electromagnet plate 5 for adsorbing magnetic powder on the filter screen 10 is installed in the mounting cavity.

[0041] Furthermore, a sewage outlet 22 is provided in the middle of the concave spherical surface, and a sewage outlet 4 extending to the outside of the cleaning box 1 is connected to the sewage outlet 22, and a sewage valve 3 is provided at the outlet end of the sewage outlet 4.

[0042] Specifically, Figure 1As shown, the concave spherical design at the bottom of the cleaning box 1 and the arrangement of the strong electromagnet plate 5, the sewage outlet 22 and the sewage pipe 4 further enhance the practicality and functionality of the cleaning device. First, the design of the concave spherical bottom not only increases the structural strength of the cleaning box 1, but also enables the bottom of the cleaning box 1 to gather sewage and impurities generated during the cleaning process. This design helps to better collect and treat these sewage and impurities, and keep the cleaning environment clean and hygienic. Secondly, during the use of the filter screen 10 of the sintering furnace, some magnetic powder may be adsorbed. If these magnetic powders are not removed in time, the filtering effect and service life of the filter screen 10 will be affected. The role of the strong electromagnet plate 5 is to adsorb the magnetic powder on the filter screen 10 through its strong magnetic force, thereby achieving deep cleaning of the filter screen 10.

[0043] In addition, the sewage outlet 22 arranged in the middle of the concave spherical surface and the connected sewage pipe 4 provide convenience for the discharge of sewage and impurities during the cleaning process. By opening the sewage valve 3, the sewage and impurities accumulated at the bottom of the cleaning box 1 can be easily discharged to keep the inside of the cleaning box 1 clean.

[0044] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
