[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides a circulating cooling and filtering device for aluminum cold rolling mill rolls, including a base plate 1, a support plate 2 fixedly mounted on the upper surface of the base plate 1, a water tank 3 and a side plate 4 fixedly mounted on the upper side of the support plate 2, a groove 11 opened on the upper surface of the base plate 1 away from the support plate 2, inclined guide blocks 12 symmetrically fixedly mounted in the groove 11, a filter plate 13 mounted in the groove 11, the two sides of the filter plate 13 respectively movably fitting with the two inclined guide blocks 12, an inclined groove 14 opened in the base plate 1, the upper side of the inclined groove 14 connected to the groove 11, a connecting pipe 15 connecting the water tank 3 and the inclined groove 14, the filtered cooling medium flows into the connecting pipe 15 through the inclined groove 14, and a first water pump 16 draws it from the inclined groove 14 into the water tank 3 to complete one cycle.

[0023] Specifically, a first water pump 16 is provided on the connecting pipe 15, and a spray plate 32 is provided on the upper side of the side plate 4. An output pipe 31 is provided between the spray plate 32 and the water tank 3. A second water pump 33 is provided on the output pipe 31. The cooling medium (such as water or emulsion) in the water tank 3 is transported to the spray plate 32 through the output pipe 31. The second water pump 33 provides power for the transport process. The spray plate 32 sprays the cooling medium evenly on the surface of the roll, absorbing the heat generated by the roll during rolling and achieving cooling.

[0024] Furthermore, two limiting plates 41 are fixedly provided on the inner side of the side plate 4, and a lead screw 42 is rotatably provided between the two limiting plates 41. A motor 43 is fixedly provided on the lower side of the lower limiting plate 41, and the output end of the motor 43 passes through one of the limiting plates 41 and is fixedly connected to the lead screw 42. A lifting block 44 is threaded on the outer surface of the lead screw 42. A connecting rod 45 is rotatably provided on one side of the lifting block 44. An adjusting plate 46 is rotatably provided on the upper end of the connecting rod 45. The lower side of the second water pump 33 is fixedly provided on the adjusting plate 46. Rotary connection with side plate 4, motor 43 inside side plate 4 starts and drives lead screw 42 to rotate. Both ends of lead screw 42 are fixed by limit plate 41 to ensure stability during rotation. When lead screw 42 rotates, lifting block 44 threaded on its outer surface moves up and down along the axis of lead screw 42. Lifting block 44 is connected to adjustment plate 46 through connecting rod 45. When lifting block 44 moves up and down, connecting rod 45 pushes adjustment plate 46 to rotate around its rotation connection point with side plate 4, thereby changing the tilt angle and height of spray plate 32 and achieving precise adjustment of spray position.

[0025] Furthermore, one side of the lifting block 44 is engaged on the side plate 4, and a reinforcing block is fixedly provided on one side of the side plate 4. The lead screw 42 moves through the reinforcing block, and one side of the lifting block 44 is engaged on the side plate 4 to ensure that it does not deviate during movement.

[0026] It is worth noting that the two sides of the filter plate 13 are movably fitted with the inner walls of the two sides of the groove 11, and the upper surface of the filter plate 13 is symmetrically fixed with an L-shaped plate 131, which is stuck in the groove 11. The two sides of the filter plate 13 are fitted with the inclined guide block 12 in the groove 11. During installation, the filter plate 13 slides into the groove 11 along the inclined guide block 12 to ensure that the position of the filter plate 13 is accurate.

[0027] It is worth noting that a handle 132 is fixedly provided on the upper surface of the L-shaped plate 131. When disassembling, the L-shaped plate 131 is lifted upward by the handle 132, so that the insertion post 133 is separated from the bottom plate 1, and the filter plate 13 can be taken out along the inclined guide block 12 for easy cleaning or replacement.

[0028] It is worth mentioning that the upper inner wall of the L-shaped plate 131 is fixedly provided with a post 133, and the post 133 is movably inserted into the bottom plate 1. The L-shaped plate 131 on the upper surface of the filter plate 13 is stuck at the edge of the groove 11, and the post 133 is inserted into the bottom plate 1, forming a double fixation to prevent the filter plate 13 from shifting during the filtration process.

[0029] The water pump and motor 43 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: The cooling medium (such as water or emulsion) in the water tank 3 is delivered to the spray plate 32 through the output pipe 31. The second water pump 33 provides power for the delivery process. The spray plate 32 sprays the cooling medium evenly on the surface of the roll, absorbing the heat generated by the roll during rolling and achieving cooling.

[0031] The sprayed cooling medium carries metal shavings, oil stains and other impurities from the surface of the roll and drips from the surface of the roll into the groove 11 of the base plate 1. The filter plate 13 in the groove 11 filters the impurities and intercepts them.

[0032] The filtered cooling medium flows into the connecting pipe 15 through the inclined groove 14. The first water pump 16 draws it from the inclined groove 14 into the water tank 3, completing one cycle. Throughout the process, the cooling medium forms a closed loop circulation between the water tank 3, the output pipe 31, the spray plate 32, the roller, the groove 11, the inclined groove 14, the connecting pipe 15, and the water tank 3.

[0033] After the motor 43 inside the side plate 4 starts, it drives the lead screw 42 to rotate. The two ends of the lead screw 42 are fixed by the limit plate 41 to ensure the stability during rotation.

[0034] When the lead screw 42 rotates, the lifting block 44, which is threaded on its outer surface, moves up and down along the axis of the lead screw 42. One side of the lifting block 44 is locked on the side plate 4 to ensure that it does not deviate during movement.

[0035] The lifting block 44 is connected to the adjusting plate 46 via the connecting rod 45. When the lifting block 44 moves up and down, the connecting rod 45 pushes the adjusting plate 46 to rotate around the rotation connection point between it and the side plate 4, thereby changing the tilt angle and height of the spraying plate 32 and achieving precise adjustment of the spraying position.

[0036] The filter plate 13 is fitted with the inclined guide block 12 in the groove 11 on both sides. During installation, it slides into the groove 11 along the inclined guide block 12 to ensure that the filter plate 13 is in the correct position.

[0037] The L-shaped plate 131 on the upper surface of the filter plate 13 is secured to the edge of the groove 11, while the insert post 133 is inserted into the bottom plate 1, forming a double fixation to prevent the filter plate 13 from shifting during the filtration process;

[0038] During disassembly, the L-shaped plate 131 is lifted upward by the handle 132, so that the insertion post 133 is detached from the base plate 1, and the filter plate 13 can be taken out along the inclined guide block 12 for easy cleaning or replacement.
