The beneficial effect of this invention, using the above technical solution, is that by rotating and moving the rotating rollers and brushes left and right, the stainless steel strip can be cleaned, thereby improving cleaning efficiency.

[0004] Although the aforementioned patent includes a brush for cleaning stainless steel, some black scale debris remains on the brush during cleaning, requiring manual disassembly and cleaning later. This disassembly and cleaning requires stopping the machine, thus affecting processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for pickling stainless steel, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The rotating tube is equipped with a rotating cleaning mechanism at one end of the cleaning tank.

[0010] The rotating tube 2 is equipped with a rotating spray mechanism at one end of the cleaning tank.

[0011] Preferably, the transmission mechanism includes a mounting bracket fixedly connected to the outside of the top right side of the cleaning tank, and a gear two fixedly connected to the outside of the end of the rotating tube two away from the cleaning tank. A motor is fixedly connected to the outside right side of the mounting bracket, and a gear one that meshes with gear two is fixedly connected to the output shaft of the motor.

[0012] Preferably, the rotary cleaning mechanism includes a brush frame evenly distributed circumferentially along the outer end of the rotating tube away from the gear, and a brush roller is rotatably connected to the end of the brush frame away from the rotating tube via a bearing.

[0013] Preferably, the rotary spraying mechanism includes spray pipes evenly distributed circumferentially along the outer end of the rotating tube two away from the gear two. The spray pipes are parallel to the outer side of the brush roller. A sealing water guide ring is fixedly connected to the inner right side of the cleaning tank and located outside the rotating tube two. A diversion plate rotatably connected to the sealing water guide ring is fixedly connected to the outer right end of the rotating tube two.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This stainless steel pickling cleaning device, through the circumferential arrangement and reverse rotation of the spray pipes, creates a relative motion between the sprayed water flow and the rotation direction of the brush roller. This enhances the rinsing force on the surface of the stainless steel pipe and automatically removes the black scale debris attached to the brush roller using the shearing action of the water flow. This achieves a self-maintenance effect for the cleaning device and solves the problem of traditional brush cleaning equipment requiring periodic shutdowns for brush bristle cleaning.

[0018] 2. This stainless steel pickling cleaning device uses the synchronous counter-rotation of a brush roller and a spray pipe. While the brush roller cleans the stainless steel pipe in the forward direction, the spray pipe rotates in the opposite direction to spray cleaning liquid. This achieves both synchronous rinsing and cleaning of the stainless steel pipe surface and secondary rinsing to remove residual wastewater when the stainless steel pipe moves in the opposite direction.

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A stainless steel pickling cleaning device includes a cleaning tank 1, with a rotating tube 2 and a rotating tube 3 rotatably connected to its left and right sides via bearings, respectively. The rotating tube 3 and the rotating tube 2 are connected by a transmission mechanism. The transmission mechanism includes a mounting bracket 4 fixedly connected to the outside of the right top edge of the cleaning tank 1, and a gear 5 fixedly connected to the outside of the rotating tube 3 at the end away from the cleaning tank 1. A motor 6 is fixedly connected to the outside of the right side of the mounting bracket 4. The output shaft of the motor 6 is fixedly connected to a gear 7 that meshes with the gear 5. The rotating tube 2 is located away from the cleaning tank 1. One end of the cleaning tank 1 is externally fixedly connected to gear 8. Gear 9 is located on the left side of the cleaning tank 1. Gear 9 and gear 7 are coaxially fixed together via a transmission shaft 10. Gear 4 11 is rotatably connected to the left side of the cleaning tank 1, between gear 9 and gear 8, via a bearing. Gear 4 11 meshes with gear 9 and gear 8. A rotating cleaning mechanism is located at one end of the rotating tube 12. The rotating cleaning mechanism includes brush holders 12 evenly distributed circumferentially along the outer side of the rotating tube 12 away from gear 8. One end of the rotating tube 2 is rotatably connected to a brush roller 13 via a bearing. A rotating spray mechanism is installed at one end of the rotating tube 3, which is located away from the gear 5. The rotating spray mechanism includes spray pipes 14 evenly distributed circumferentially along the outer side of the rotating tube 3 away from the gear 5. The spray pipes 14 are parallel to the outer side of the brush roller 13. A sealing water guide ring 15 is fixedly connected to the inner right wall of the cleaning tank 1, located outside the rotating tube 3. A diversion plate 16, rotatably connected to the sealing water guide ring 15, is fixedly connected to the outer right end of the rotating tube 3. The diversion plate 16 and the sealing water guide ring 15 are axially... An O-ring 17 is provided between the contact surfaces. The rotating spray mechanism also includes a diversion cavity 18 opened inside the diversion plate 16. The input end of the spray pipe 14 is connected to the diversion cavity 18 of the diversion plate 16 through the diversion pipe 19. A circulation pump 20 is fixedly installed on the lower right side of the cleaning tank 1. The input end of the circulation pump 20 extends to the lower right side of the cleaning tank 1 and is fixedly connected to a filter 22. A drain port 23 is fixedly connected to the bottom left side of the cleaning tank 1. The output end of the circulation pump 20 is connected to the input end of the sealing water guide ring 15 through the output pipe 21.

[0027] In this embodiment, by cooperating with the brush roller 13 and the spray pipe 14 in opposite synchronous rotation, while the brush roller 13 is brushing and cleaning the stainless steel pipe in the forward direction, the spray pipe 14 is rotating in the opposite direction to spray cleaning liquid. This achieves both synchronous rinsing and cleaning of the surface of the stainless steel pipe and secondary rinsing to remove residual sewage on the surface when the stainless steel pipe moves in the direction of the rotating pipe 3.

[0028] Furthermore, by circumferentially arranging and rotating the spray pipes 14 in the opposite direction, the sprayed water flow and the rotation direction of the brush roller 13 form a relative motion, which not only enhances the rinsing force on the surface of the stainless steel pipe, but also automatically removes the black skin debris attached to the brush roller 13 by utilizing the shearing effect of the water flow, achieving the self-maintenance effect of the cleaning device and solving the problem that traditional brush cleaning equipment needs to be stopped regularly to clean the brush bristles.

[0029] Working principle: When cleaning stainless steel pipes, motor 6 is started, and its output shaft drives gear 7 to rotate. Gear 7 meshes with gear 5 to drive rotating pipe 3 to rotate. At the same time, gear 7 drives gear 9 to rotate synchronously through transmission shaft 10. Gear 9 transmits power to gear 8 through gear 4 11, causing rotating pipe 2 to rotate in the opposite direction to rotating pipe 3. Rotating pipe 2 drives the circumferentially distributed brush holder 12 and brush roller 13 to revolve. When brush roller 13 contacts the stainless steel surface, it rotates to achieve the brushing effect. During the rotation of spray pipe 14 driven by rotating pipe 3, circulation pump 2... After the liquid at the bottom of the cleaning tank 1 is filtered by the filter 22, it is pumped into the sealed water guide ring 15 through the output pipe 21. The liquid is distributed to each branch pipe 19 through the branch chamber 18 of the branch plate 16, and finally sprayed out radially from the rotating spray pipe 14 to form a dynamic rinsing surface. The sprayed liquid and the rotating brush roller 13 form a synergistic cleaning effect. The dirt washed off settles to the bottom of the cleaning tank 1 with the liquid. Some of the liquid is recycled by the circulation pump 20. The sediment is finally discharged through the drain port 23. The combination of mechanical brushing by the brush roller 13 and dynamic rinsing by the spray pipe 14 achieves efficient cleaning of pickling residue on the stainless steel surface.
