As one of the important metal forming equipment, the ring rolling machine is widely used in high-end equipment manufacturing fields such as aerospace, automobile manufacturing, and wind power. In the working process of the ring rolling machine, cooling water plays a vital role. It can not only take away the heat generated during the processing and prevent the workpiece and tools from overheating and deformation, but also wash away the metal chips and other impurities generated during the processing, ensuring the cleanliness of the processing environment, thereby improving the quality of the product and extending the service life of the equipment.

[0003] However, in actual applications, if the cooling water is not effectively filtered and purified, a large amount of pollutants such as metal powder, cutting fluid residue, oil pollution and microorganisms will gradually accumulate.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0020] like Figures 1 to 7 As shown, a ring rolling machine cooling water purification device of the present invention comprises a treatment barrel 1, the axis of the treatment barrel 1 is horizontal, support rings 2 are fixed on both sides of the inner wall of the treatment barrel 1, the two support rings 2 are coaxial, a filter cartridge 3 is rotatably arranged between the two support rings 2, the two support rings 2 and the filter cartridge 3 form a cylindrical shape, and an inlet pipe 4 and an overflow pipe 5 are arranged on the outer wall of the treatment barrel 1, the inlet pipe 4 is connected to the inside of the treatment barrel 1, and the overflow pipe 5 is connected to the inside of the support ring 2; The overflow pipe 5 is used to limit the water level in the support ring 2. A cleaning structure is provided in the treatment barrel 1, and the cleaning structure includes: The guide plate 6 is installed between the support ring 2 and the inner wall of the treatment barrel 1, and the filter cartridge 3 is in contact with the guide plate 6. A discharge port 10 is provided on the outer wall of the treatment barrel 1, and the discharge port 10 is aligned with the guide plate 6; The partition plate 7 is located inside the support ring 2 and the filter cartridge 3 and is used to separate the internal space of the support ring 2 and the filter cartridge 3; The water pump 8 is installed on the side wall of the treatment barrel 1 . The input end of the water pump 8 is connected to the inside of the support ring 2 . The output end of the water pump 8 is provided with a water pipe 9 , which is connected to the inside of the partition 7 .

[0021] In detail, waste water is introduced into the treatment barrel 1 through the water inlet pipe 4, and the waste water in the treatment barrel 1 passes through the filter cartridge 3 and enters the inner side of the filter cartridge 3. The filter cartridge 3 intercepts and treats particulate impurities in the waste water. When the waste water level in the filter cartridge 3 reaches the specified requirement, the waste water overflows to the outside through the overflow pipe 5, so that the waste water level in the filter cartridge 3 is limited by the overflow pipe 5, so that the water surface is below the partition 7. The partition 7 separates the cylindrical space composed of the support ring 2 and the filter cartridge 3. The space on the lower side is used to store the filtered waste water, and the space on the upper side is used for backwashing of the cleaning structure. The filter cartridge 3 rotates and can carry the waste water attached to the surface of the filter cartridge 3 or blocked in The impurities in the filter holes on the filter cartridge 3 move. When part of the filter cartridge 3 moves to the position of the partition 7, the water pump 8 extracts part of the filtered water in the filter cartridge 3 and discharges it into the partition 7 through the water guide pipe 9. The high part of the water is used to backwash the filter cartridge 3 at the position of the partition 7 from the inside to the outside. At this time, the backwashing water can clean and remove the impurities on the filter cartridge 3. The impurities fall onto the guide plate 6 and are discharged through the discharge port 10. As the filter cartridge 3 continues to rotate, the filter cartridge 3 is continuously filtered while the wastewater is continuously backwashed, ensuring that the filter cartridge 3 always has a high fluidity, increasing the continuous operation time of the equipment, and thus improving the wastewater treatment efficiency.

[0022] It should be pointed out that by utilizing the overflow pipe 5 , the height positions of the liquid levels in the treatment barrel 1 and the filter cartridge 3 can be limited to avoid mutual interference between the filtration area in the middle and lower part of the filter cartridge 3 and the backwashing area on the upper side of the filter cartridge 3 .

[0023] Furthermore, the axis of the support ring 2 and the axis of the filter cartridge 3 are both inclined, the material guide plate 6 is coplanar with the axis of the filter cartridge 3 , and the material guide plate 6 is inclined.

[0024] In detail, by making the filter cartridge 3 and the guide plate 6 in an inclined state, when backwashing is performed, water passing through the filter cartridge 3 and flowing out from the inside of the filter cartridge 3 can flow naturally at an inclination on the filter cartridge 3 and the guide plate 6, thereby helping the impurities of backwashing to be automatically discharged, reducing the difficulty of impurity cleaning and improving the impurity cleaning effect.

[0025] Furthermore, the material guide plate 6 is located on a side where a local area of ​​the filter cartridge 3 moves downward, the material guide plate 6 is fixedly connected to the support ring 2 , and the material guide plate 6 is in sliding contact with the filter cartridge 3 .

[0026] In detail, when the filter cartridge 3 rotates, one of the front and rear sides of the filter cartridge 3 moves upward, and the other side moves downward. The guide plate 6 is located on the side where the filter cartridge 3 moves downward. When the filter cartridge 3 rotates, the side that moves upward will carry impurities and move upward synchronously. Therefore, the surface of the filter cartridge 3 at this position is uneven. After the filter cartridge 3 is backwashed, the impurities on its surface fall off and the surface of the filter cartridge 3 returns to a flat state. At this time, the filter cartridge 3 can perfectly contact with the guide plate 6, and the guide plate 6 and the partition 7 cooperate to prevent the backwashed water on the guide plate 6 from flowing into the filter cartridge 3 again. At the same time, the guide plate 6 can scrape off the impurities on the surface of the filter cartridge 3.

[0027] Furthermore, the filter cartridge 3 vibrates back and forth along the axis direction of the support ring 2 .

[0028] In detail, since stubborn impurities are not easy to fall off during backwashing of the filter cartridge 3, the impurities on the filter cartridge 3 can be easily cleaned by the vibration of the filter cartridge 3. At the same time, when the filter cartridge 3 rotates, the impurities are not easy to be adsorbed on the surface of the filter cartridge 3, so that the backwashing work only targets the impurities that block the filter holes on the filter cartridge 3.

[0029] Furthermore, the partition 7 is in a right-angled shape, one right-angled side of the partition 7 is vertical, the other right-angled side of the partition 7 is coplanar with the guide plate 6, and a slot 11 is provided on both right-angled sides of the partition 7, and the filter cartridge 3 is clamped in the slot 11; The two ends of the partition plate 7 pass through the processing barrel 1 and slide relatively.

[0030] In detail, by limiting the shape of the partition 7, the part of the filter cartridge 3 carrying impurities can move to the area corresponding to the partition 7 only after passing its highest point. In this way, the impurities for backwashing will flow directly to the guide plate 6 along the surface of the filter cartridge 3, and will not move away from the guide plate 6 and flow back into the wastewater. By providing a slot 11 on the partition 7, the partition 7 can be perfectly engaged with the filter cartridge 3, and when the filter cartridge 3 vibrates, the filter cartridge 3 will drive the partition 7 to slide on the treatment barrel 1.

[0031] Furthermore, the processing barrel 1 is provided with a power unit for providing power for the rotation and vibration of the filter cartridge 3; The power unit includes a transmission shaft 12, one end of which is provided with a transmission column 13, which is located inside the filter cartridge 3 and is in transmission connection with each other, both ends of the transmission column 13 are provided with limiting ribs 14, and the two limiting ribs 14 are clamped on the two end surfaces of the filter cartridge 3, and the other end of the transmission shaft 12 is provided with a second transmission wheel 17, which is located outside the treatment barrel 1, and the transmission shaft 12 slides through the treatment barrel 1; A motor 15 is fixed on the outer wall of the treatment barrel 1 , and a first transmission wheel 16 is provided at the output end of the motor 15 . The first transmission wheel 16 is transmission-connected with the second transmission wheel 17 . The first transmission wheel 16 is inclined, and a locking structure is provided between the first transmission wheel 16 and the second transmission wheel 17 .

[0032] In detail, the axis of the transmission shaft 12 is parallel to the axis of the filter cartridge 3, so the transmission shaft 12 is also in an inclined state, the rotation axis of the first transmission wheel 16 is parallel to the axis of the transmission shaft 12, the axis of the circumferential outer wall of the first transmission wheel 16 is parallel to the axis of the transmission shaft 12, and the surface where the first transmission wheel 16 is located is relatively inclined to the axis of the transmission shaft 12. In this way, when the motor 15 drives the second transmission wheel 17 to rotate through the first transmission wheel 16, the first transmission wheel 16 will push the second transmission wheel 17 to reciprocate along the axis direction of the transmission shaft 12, and the locking structure realizes the connection between the first transmission wheel 16 and the second transmission wheel 17. At this time, the second transmission wheel 17 can both rotate and vibrate. The second transmission wheel 17 drives the transmission column 13 and the limiting rib 14 to move synchronously through the transmission shaft 12, the transmission column 13 drives the filter cartridge 3 to rotate, and the two limiting ribs 14 drive the filter cartridge 3 to vibrate.

[0033] Furthermore, the locking structure includes a cross bar 18 fixed on the outer wall of the processing barrel 1, and two slides 19 are slidably arranged on the cross bar 18, and a support column 20 is fixed on each slide 19. Auxiliary wheels 21 are rotatably arranged at both ends of the support column 20, one auxiliary wheel 21 is in transmission contact with the second transmission wheel 17, and the other auxiliary wheel 21 is in transmission contact with the first transmission wheel 16, and the two support columns 20 are respectively located on the left and right sides of the first transmission wheel 16.

[0034] In detail, the four auxiliary wheels 21 on the two support columns 20 can be used to limit the first transmission wheel 16 and the second transmission wheel 17, so that the first transmission wheel 16 and the second transmission wheel 17 always maintain a transmission state. Since the surface where the first transmission wheel 16 is located is relatively inclined to the axis of the transmission shaft 12, the contact position of the first transmission wheel 16 and the second transmission wheel 17 will be displaced in the direction of the axis of the transmission shaft 12. By utilizing this displacement and the locking structure, the vibration of the second transmission wheel 17 along the axis of the transmission shaft 12 is realized. The first transmission wheel 16 pushes the slide 19 to slide on the cross bar 18 through the auxiliary wheels 21 and the support columns 20, and the first transmission wheel 16 and the second transmission wheel 17 respectively drive the corresponding auxiliary wheels 21 to rotate.

[0035] Furthermore, the bottom of the treatment barrel 1 is connected to a collection barrel 22 , and a barrel cover 23 is sealed on the bottom opening of the collection barrel 22 .

[0036] In detail, after long-term treatment, some impurities in the wastewater in the treatment barrel 1 will naturally settle into the collection barrel 22. In this way, the collection barrel 22 can be used to collect these impurities. When the equipment is shut down or overhauled, the barrel cover 23 can be opened to drain the wastewater and impurities in the treatment barrel 1.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
