DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0023] Referring to Figures 1 to 8 A medical waste plastic recycling and regeneration treatment equipment, including a cleaning tank 1, the cleaning tank 1 is provided with a discharge port 101 at one end, a rotating roller 2 is rotatably installed on the inner side wall of the cleaning tank 1 near the discharge port 101, a plurality of fishing nets 3 are fixedly installed on the outer side wall of the rotating roller 2, and the plurality of fishing nets 3 are arranged in an annular array, the fishing net 3 is arranged in an arc shape with one end open and the other end sealed, when the broken plastic fragments are cleaned in the cleaning tank 1, the rotating roller 2 is driven to rotate clockwise (for example), the fishing net 3 on the outer surface of the rotating roller 2 rotates to the inside of the cleaning tank 1, and the fishing net 3 is used to fish the plastic fragments in the cleaning liquid through the open end of the fishing net 3, and after fishing, the fishing net 3 continues to rotate, the cleaning liquid in the fishing net 3 flows out through the filter hole on the fishing net 3, when the fishing net 3 containing plastic fragments rotates to the end near the discharge port 101, the fishing net 3 is washed from the outer surface thereof by using a related water spraying device, so that the plastic fragments in the fishing net 3 are washed out and fall to the next cleaning tank 1 through the discharge port 101. Figure 1

[0024] Referring to Figures 1 to 4 ​An adjusting frame 4 is slidably mounted on the outer surface of the fishing net 3. Multiple adjusting plates 5 arranged in a circular array are fixedly mounted on the adjusting frame 4 to change the aperture size of the filter holes on the fishing net 3. Multiple support columns 7 are symmetrically fixedly mounted at both ends of the rotating roller 2. The axis of the support column 7 coincides with the axis of the arc-shaped fishing net 3. An adjusting ring 8 is rotatably mounted on the outer side of the support column 7 through an elastic element. The elastic element is used to reset the adjusting ring 8. A connecting rod 9 is fixedly mounted on the outer side of the adjusting ring 8, and the end of the connecting rod 9 away from the adjusting ring 8 is fixedly connected to the adjusting frame 4. When the cleaning tank 1 is running, the adjusting frame 4, the support columns 7, and the connecting rod 9 rotate together with the rotating roller 2. When the adjusting ring 8 or the connecting rod 9 is subjected to force and rotates around the axis of the support column 7, it can also drive the adjusting frame 4 to slide on the outer surface of the fishing net 3 through the connecting rod 9, thereby changing the aperture size of the filter holes on the fishing net 3 through the adjusting plates 5.

[0025] See Figures 4 to 8 Multiple toothed blocks 10 are fixedly installed on the outer side of the adjusting ring 8 away from the support column 7. A toothed ring 11, which meshes with or separates from the toothed blocks 10, is fixedly installed on the inner wall of the cleaning tank 1. The toothed ring 11 is positioned at the end of the rotating roller 2 away from the discharge port 101. When the catching net 3 is placed in the cleaning liquid to scoop up plastic fragments, the adjusting plate 5 on the adjusting frame 4 partially blocks the filter holes on the catching net 3 to reduce the aperture, allowing small fragments in the cleaning liquid to be scooped up together, reducing the residual amount of small fragments in the cleaning tank 1, and preventing the small fragments from remaining inside the cleaning tank 1 for a long time and affecting the concentration of the cleaning liquid's chemicals. Figure 2 For example, after the fishing net 3 containing plastic fragments rotates out of the liquid surface, it gradually approaches the toothed ring 11. When the corresponding toothed block 10 meshes with the toothed ring 11, under the action of the toothed ring 11, the toothed block 10 drives the corresponding adjusting ring 8 and connecting rod 9 to rotate counterclockwise, thereby relieving the blockage of the filter holes by the adjusting plate 5, allowing the cleaning liquid in the fishing net 3 to flow out. This prevents the cleaning liquid in the fishing net 3 from entering the interior of the next cleaning tank 1 along with the plastic fragments, affecting the cleaning effect of the next cleaning tank 1. It also ensures that when the fishing net 3 approaches the discharge port 101, it does not affect the impact of the water spraying equipment on the fishing net 3 and the plastic fragments inside the fishing net 3, preventing the plastic fragments from adhering to the inner wall of the fishing net 3 and not falling off. Thus, while achieving the purpose of catching small fragments, it ensures the drainage effect and the dumping rate of plastic fragments.

[0026] See Figures 4 to 7The limiting post 12 is fixedly installed on the outer side wall of the rotating roller 2 close to the connecting rod 9, the limiting rod 13 is slidably connected to the limiting post 12 through the spring 14 far away from the connecting rod 9, the rolling ball 15 is rotatably installed on the end of the limiting rod 13 far away from the limiting post 12, the main clamping groove 16 is formed in the outer side wall of the rotating roller 2 and matched with the rolling ball 15, the auxiliary clamping groove 17 is formed in the inner bottom wall of one end of the main clamping groove 16, when the rolling ball 15 is placed in the main clamping groove 16 far away from the auxiliary clamping groove 17, the spring 14 is compressed, the adjusting plate 5 does not block the filter hole on the fishing net 3, when the fishing net 3 loaded with plastic fragments passes through the toothless ring 11, the limiting post 12, the limiting rod 13 and the rolling ball 15 slide synchronously with the connecting rod 9, and then the rolling ball 15 slides to the auxiliary clamping groove 17, under the action of the spring 14, the rolling ball 15 is placed in the auxiliary clamping groove 17, and then the position of the connecting rod 9 is limited through the rolling ball 15 and the auxiliary clamping groove 17, so that the adjusting plate 5 does not block the filter hole again when the fishing net 3 rotates with the rotating roller 2, the draining effect and the dumping rate of the plastic fragments are not affected, and the normal transfer of the plastic fragments is ensured.

[0027] Referring to Figures 1 to 6 The outer side of the limiting rod 13 is fixedly installed with the supporting rod 18, the supporting rod 18 is fixedly installed with the L-shaped unlocking rod 181 far away from the limiting rod 13, the inner side wall of the cleaning tank 1 is fixedly installed with the two supporting shafts 19 symmetrically, the supporting shaft 19 is fixedly installed with the unlocking plate 20 far away from the cleaning tank 1, the unlocking plate 20 is placed on the side of the toothless ring 11 close to the discharge port 101, and the two ends of the unlocking plate 20 are roundly arranged, when the fishing net 3 loaded with plastic fragments passes through the toothless ring 11, the adjusting plate 5 maintains the state of not blocking the filter hole on the fishing net 3 under the action of the spring 14, and when the plastic fragments in the fishing net 3 fall out under the action of the gravity and the water spraying equipment, the fishing net 3, the connecting rod 9 and the unlocking rod 181 gradually approach the unlocking plate 20, until the end of the unlocking rod 181 far away from the supporting rod 18 contacts with the unlocking plate 20, the unlocking rod 181 drives the supporting rod 18 and the limiting rod 13 to slide to the inner side wall of the cleaning tank 1 through the extrusion of the two ends of the unlocking plate 20, so that the rolling ball 15 slides out of the auxiliary clamping groove 17, the limiting clamping of the rolling ball 15 by the auxiliary clamping groove 17 is released, the adjusting ring 8 and the connecting rod 9 can be reset under the action of the elastic member, so that the adjusting plate 5 blocks the filter hole on the fishing net 3 again, and the next fishing of the fishing net 3 is facilitated.

[0028] Referring to Figures 1 to 4The side wall of the adjusting plate 5 is fixedly provided with a plurality of clamping rods 6, the plurality of clamping rods 6 are matched with corresponding filter holes respectively, and the clamping rod 6 is arranged in an arc shape. When the adjusting plate 5 blocks the filter holes on the fishing net 3 after the fishing net 3 completes the dumping of the plastic fragments and passes through the unlocking plate 20, the end of the clamping rod 6 away from the adjusting plate 5 extends into the inside of the fishing net 3 through the filter hole, that is, a convex state is formed at the filter hole in the fishing net 3, so that the filter hole is in a state of coexistence of the plastic fragments and the label paper, to prevent the label paper in the cleaning liquid from blocking the filter hole when the fishing net 3 captures the plastic fragments. With the fishing net 3 capturing the plastic fragments and passing through the toothless ring 11, the blocking of the filter holes on the fishing net 3 by the adjusting plate 5 is released, and the end of the clamping rod 6 away from the adjusting plate 5 slides with the adjusting plate 5, to prevent the clamping rod 6 from affecting the impact effect of the water spraying equipment on the fishing net 3.

[0029] Working principle:

[0030] When the medical waste plastic is recycled and processed, the broken plastic fragments are cleaned in the cleaning tank 1. The rotating roller 2 is driven to rotate clockwise by the driving device. The fishing net 3 on the outer surface of the rotating roller 2 rotates to enter the cleaning liquid in the cleaning tank 1. The ball 15 is placed in the main clamping groove 16, and the adjusting plate 5 blocks the filter holes on the fishing net 3 under the action of the spring 14. The aperture of the filter hole is reduced, and the end of the clamping rod 6 away from the adjusting plate 5 also extends into the inside of the fishing net 3 through the filter hole, to prevent the label paper in the cleaning liquid from blocking the filter hole and affecting the draining and dumping of the plastic fragments. With the fishing net 3 entering the cleaning liquid and capturing the plastic fragments in the cleaning liquid through the opening end of the fishing net 3, the fishing net 3 continues to rotate in the direction of the toothless ring 11 after capturing. When the corresponding tooth block 10 is engaged with the toothless ring 11, the tooth block 10 drives the corresponding adjusting ring 8 and the connecting rod 9 to rotate counterclockwise under the action of the toothless ring 11, thereby releasing the blocking of the filter holes by the adjusting plate 5. The cleaning liquid in the fishing net 3 can flow out, to prevent the cleaning liquid in the fishing net 3 from entering the inside of the next cleaning tank 1 together with the plastic fragments, affecting the cleaning effect of the next cleaning tank 1, and also preventing the plastic fragments from adhering to the inner wall of the fishing net 3 and failing to fall, thereby achieving the purpose of capturing small fragments while ensuring the draining effect and the dumping rate of the plastic fragments.

[0031] When the fishing net 3 equipped with plastic fragments passes through the toothless ring 11, the limiting column 12, the limiting rod 13 and the rolling ball 15 and the like slide synchronously with the connecting rod 9, and then the rolling ball 15 slides to the secondary clamping groove 17, and under the elastic force of the spring 14, the rolling ball 15 is placed in the secondary clamping groove 17, and then after the adjusting plate 5 unblocks the filter hole, the position of the connecting rod 9 is limited by the rolling ball 15 and the secondary clamping groove 17, so as to prevent the adjusting plate 5 from blocking the filter hole again when the fishing net 3 rotates with the rotating roller 2, and to prevent the draining effect and the dumping rate of the plastic fragments from being affected, to ensure the normal transfer of the plastic fragments, and then the fishing net 3 and the plastic fragments in the fishing net 3 after draining gradually move towards the discharge port 101, and then the fishing net 3 is washed from the outer surface by using the related water spraying equipment, so as to flush out the plastic fragments in the fishing net 3 and make them fall into the next cleaning tank 1 through the discharge port 101, and then the fishing net 3 after discharging moves towards the unlocking plate 20 with the rotating roller 2, until the end of the unlocking rod 181 far away from the supporting rod 18 contacts with the unlocking plate 20, the unlocking rod 181 is extruded by the smooth setting of the two ends of the unlocking plate 20, so as to drive the supporting rod 18 and the limiting rod 13 to slide towards the inner wall of the cleaning tank 1, and then the rolling ball 15 slides out of the secondary clamping groove 17, the secondary clamping groove 17 unblocks the limiting clamping of the rolling ball 15, the adjusting ring 8 and the connecting rod 9 can be reset under the action of the elastic member, so as to block the filter hole of the fishing net 3 again, and facilitate the next fishing of the fishing net 3.

[0032] By adjusting the position of the frame 4, the adjusting plate 5 and the clamping rod 6 during the rotation of the fishing net 3 with the rotating roller 2, the size of the filter hole of the fishing net 3 is changed, so as to keep a small aperture during the fishing of the plastic fragments, to improve the fishing probability of the small fragments, to reduce the percentage of the small fragments in the cleaning tank 1, to reduce the resource waste and to improve the recovery rate, to prevent the label paper in the cleaning liquid from blocking the filter hole, and to drain in time after the fishing is completed, so as to prevent the cleaning liquid in the fishing net 3 from entering the next cleaning tank 1 with the plastic fragments, to ensure the dumping rate of the plastic fragments in the fishing net 3 without affecting the transfer efficiency, to ensure the smoothness and integrity of the dumping, and to ensure that the whole processing flow can be carried out in order according to the predetermined time node, and to ensure the normal progress of the recovery processing period.
