Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, specifically to an energy-saving coating device for steel structures. Background Technology

[0002] In the processing and manufacturing of steel structures, a coating treatment is usually required to improve the corrosion resistance and wear resistance of the steel structure. Existing steel structure coating devices mostly use a pump to extract the coating liquid and apply it evenly to the steel structure surface through spraying or other methods. To ensure the purity of the coating liquid and prevent impurities from clogging the nozzles or affecting the coating quality, a filter screen is usually installed on the pump to filter the coating liquid.

[0003] However, in actual use, this coating device has significant drawbacks. Solid particles, flocculants, or other impurities in the coating solution easily adhere to and accumulate on the filter screen during the material extraction process, leading to filter clogging. Once the filter screen is clogged, the pump needs to overcome greater resistance to extract the coating solution, resulting in increased pump power and significantly increased energy consumption. Simultaneously, the extraction efficiency decreases, reducing the overall production efficiency of the coating process. Furthermore, the frequently clogged filter screen requires regular manual cleaning or replacement, increasing maintenance costs and causing production interruptions due to downtime for cleaning, further impacting production schedules.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving coating device for steel structures to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an energy-saving coating device for a steel structure, including a support and a steel strip body. A collection trough is installed on the support, and a conveying roller for conveying the steel strip body is installed on the collection trough. A suction pump is installed on the side wall of the collection trough. A suction pipe is connected to the input end of the suction pump, and a spray pipe is connected to the output end of the suction pump. The end of the suction pipe away from the suction pump extends into the collection trough and is connected to a flexible pipe. A rigid pipe is connected to the flexible pipe. A filter cartridge is connected to the end of the rigid pipe away from the flexible pipe. A rotating rod is rotatably connected inside the rigid pipe. The top end of the rotating rod extends from the top surface of the filter cartridge and is connected to a connecting rod. The connecting rod extends radially along the filter cartridge, and a scraper is connected to the end of the connecting rod. The scraper fits against the outer wall of the filter cartridge. A driving component for driving the rotating rod to rotate is also provided inside the rigid pipe.

[0007] Furthermore, the driving component is an impeller, the bottom end of the rotating rod extends into the interior of the rigid tube, and the impeller is connected to the bottom end of the rotating rod.

[0008] Furthermore, a support rod is installed inside the rigid tube, and the rotating rod is rotatably connected to the support rod.

[0009] Furthermore, a support spring is fitted on the outer wall of the soft tube, the top end of the support spring is connected to the outer wall of the hard tube, and the bottom end of the support spring is connected to the inner bottom wall of the collection trough.

[0010] Furthermore, an adjusting plate is rotatably installed on the inner bottom wall of the collection trough, and an adjusting groove is provided on the adjusting plate. An extension rod extending axially along the rigid tube is provided on the side wall of the scraper, and the extension rod is inserted into the interior of the adjusting groove.

[0011] Furthermore, a filter plate is installed on the top of the collection trough, and the filter plate completely covers the opening of the collection trough.

[0012] Furthermore, the spray pipe extends to the upper part of the steel strip body, and the spray pipe is provided with spray nozzles in sequence relative to the steel strip body.

[0013] Furthermore, the filter cartridge has a top-sealed and bottom-open structure, with its open end fixedly sleeved on the outside of a rigid tube, and filter holes are evenly distributed on the side wall of the filter cartridge.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model features an automatic cleaning mechanism that ensures the cleanliness of the filter cartridge, significantly reducing the number of downtime cleanings caused by filter clogging. It avoids the additional energy consumption required to restart the equipment, while improving production continuity. This allows for lower energy consumption when producing the same number of coated steel structures per unit time, further enhancing energy efficiency.

[0016] 2. In this utility model, the cylinder swings and changes position due to the trajectory of the adjustment groove under the drive of the extension rod, which causes the scraped impurities to move away from the filter cylinder quickly, significantly reducing the possibility of impurities re-attaching, effectively preventing filter cylinder blockage, reducing the energy consumed by the suction pump due to the increased resistance of the filter screen, and ensuring stable and energy-saving operation of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: an energy-saving coating device with a steel structure, including a support 1 and a steel strip body 5. A collection trough 2 is installed on the support 1, and a conveying roller 4 for conveying the steel strip body 5 is installed on the collection trough 2. A suction pump 6 is installed on the side wall of the collection trough 2. A suction pipe 7 is connected to the input end of the suction pump 6, and a spray pipe 8 is connected to the output end of the suction pump 6. The end of the suction pipe 7 away from the suction pump 6 extends into the collection trough 2 and is connected to a soft pipe 9. A rigid pipe 10 is connected to the soft pipe 9. A filter cylinder 11 is connected to the end of the rigid pipe 10 away from the soft pipe 9. A rotating rod 14 is rotatably connected inside the rigid pipe 10. The top end of the rotating rod 14 extends from the top surface of the filter cylinder 11 and is connected to a connecting rod 15. The connecting rod 15 extends radially along the filter cylinder 11, and a scraper 18 is connected to the end of the connecting rod 15. The scraper 18 is in contact with the outer wall of the filter cylinder 11. A driving component for driving the rotating rod 14 to rotate is also provided inside the rigid pipe 10.

[0025] Specifically, during the coating process on the steel strip body 5, the suction pump 6 draws the coating liquid from the collection tank 2 through the suction pipe 7. The end of the suction pipe 7 is connected to the flexible pipe 9, the rigid pipe 10, and the filter cartridge 11. The filter cartridge 11 filters the coating liquid to prevent impurities from entering the suction pump 6 and the spray pipe 8. The drive component inside the rigid pipe 10 drives the rotating rod 14 to rotate. The rotating rod 14 drives the connecting rod 15 and the scraper 18 to rotate. The scraper 18 fits against the outer wall of the filter cartridge 11 to scrape off the impurities attached to the outer wall of the filter cartridge 11, preventing the filter cartridge 11 from becoming clogged. The filtered coating liquid is pumped by the suction pump 6 to the spray pipe 8, and sprayed onto the surface of the steel strip body 5 through the spray pipe 8. The coating liquid is filtered by the filter cartridge 11 to ensure the purity of the coating liquid. At the same time, the drive component drives the scraper 18 to scrape off impurities from the outer wall of the filter cartridge 11, effectively preventing the filter cartridge 11 from clogging. This reduces the energy consumption of the suction pump 6 due to overcoming the resistance of the filter screen, improves the material extraction efficiency and the production efficiency of coating processing, and reduces the cost of manual cleaning or replacement of the filter screen and the production interruption caused by machine shutdown for cleaning.

[0026] As a technical optimization of this utility model, the driving component is an impeller 16, the bottom end of the rotating rod 14 extends into the interior of the rigid tube 10, and the impeller 16 is connected to the bottom end of the rotating rod 14.

[0027] As a technical optimization of this utility model, a support rod 13 is installed inside the rigid tube 10, and a rotating rod 14 is rotatably connected to the support rod 13.

[0028] As a technical optimization of this utility model, a support spring 17 is sleeved on the outer wall of the soft tube 9. The top end of the support spring 17 is connected to the outer wall of the hard tube 10, and the bottom end of the support spring 17 is connected to the inner bottom wall of the collection trough 2.

[0029] Specifically, the support spring 17 enhances the stability of the soft tube 9 and the hard tube 10, preventing them from shifting or shaking due to external forces during operation. This ensures the stability and reliability of the filter cartridge 11 cleaning process, while also reducing potential damage to the soft tube 9 and the hard tube 10 caused by shaking, thus extending the service life of the device.

[0030] As a technical optimization of this utility model, an adjustment plate 19 is rotatably installed on the inner bottom wall of the material collection trough 2. An adjustment groove 20 is opened on the adjustment plate 19. An extension rod 12 extending along the axial direction of the rigid tube 10 is provided on the side wall of the scraper 18. The extension rod 12 is inserted into the interior of the adjustment groove 20.

[0031] Specifically, by setting the adjustment plate 19 and the adjustment groove 20, the position and angle of the scraper 18 can be flexibly adjusted, which can adapt to the distribution of impurities on the outer wall of the filter cartridge 11 under different working conditions, improve the comprehensiveness and effectiveness of cleaning the filter cartridge 11, and further ensure the filtration effect of the filter cartridge 11 and the normal operation of the device.

[0032] As a technical optimization of this utility model, a filter plate 3 is installed on the top of the material collection tank 2, and the filter plate 3 completely covers the opening of the material collection tank 2.

[0033] Specifically, the filter plate 3 performs preliminary filtration of impurities entering the collection tank 2, reducing the impurity content in the coating liquid, lowering the possibility of filter cartridge 11 clogging, extending the service life of filter cartridge 11, and also ensuring the purity of the coating liquid and improving the coating quality.

[0034] As a technical optimization of this utility model, the spray pipe 8 extends to the upper part of the steel strip body 5, and the spray pipe 8 is provided with spray nozzles in sequence relative to the steel strip body 5.

[0035] Specifically, by rationally setting the position and layout of the spray pipes 8 and spray nozzles, it is possible to ensure that the coating liquid is evenly applied to the surface of the steel strip body 5, thereby improving the uniformity and quality of the coating and ensuring the corrosion resistance, wear resistance and other properties of the steel structure.

[0036] As a technical optimization of this utility model, the filter cartridge 11 has a top-sealed and bottom-open structure, with its open end fixedly sleeved on the outside of the rigid tube 10, and filter holes are evenly distributed on the side wall of the filter cartridge 11.

[0037] Specifically, the special structural design of the filter cartridge 11 enables it to filter effectively, effectively intercept impurities, and ensure the purity of the coating liquid entering the suction pump 6 and spray pipe 8. At the same time, this structure facilitates the scraper 18 to clean impurities on the outer wall of the filter cartridge 11, improving the practicality and reliability of the device.

[0038] Working principle: During the operation of the steel structure energy-saving coating device, the suction pump 6 draws the coating liquid from the collection tank 2, and the filter cartridge 11 filters the coating liquid, with impurities adhering to the outer wall of the filter cartridge 11. The coating liquid flows in the rigid pipe 10, impacting the impeller 16 and driving the rotating rod 14 to rotate. The rotating rod 14 drives the scraper 18 to rotate against the outer wall of the filter cartridge 11 through the connecting rod 15, thus cleaning the filter cartridge 11.

[0039] An extension rod 12, located on the side wall of the scraper rod 18, is inserted into the adjustment groove 20 of the adjustment plate 19. The adjustment groove 20 has a specific shape trajectory. When the scraper rod 18 rotates with the rotating rod 14, the extension rod 12 moves along the shape trajectory of the adjustment groove 20. Due to the guiding effect of the trajectory of the adjustment groove 20, the extension rod 12 will be displaced during the movement, thereby causing the scraper rod 18 to undergo lateral, longitudinal, or combined lateral displacement changes.

[0040] The flexible tube 9 is flexible, and the support spring 17 sleeved on its outer wall provides support and cushioning for both the flexible tube 9 and the rigid tube 10. When the scraper 18 is displaced, it drives the connected rigid tube 10 and filter cartridge 11 to move. The flexible tube 9 bends and deforms accordingly, causing the filter cartridge 11 to swing and change its position within the collection trough 2. During the position change and swinging of the filter cartridge 11, the scraped impurities are more easily removed from the area around the filter cartridge 11 under the influence of gravity, water flow, and the inertia generated by the movement of the filter cartridge 11. This prevents the cleaned impurities from re-adhering to the surface of the filter cartridge 11, ensuring the filtration effect of the filter cartridge 11.

[0041] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
