Technical Field
[0001] This utility model relates to the field of medical waste pulverization technology, specifically a medical waste pulverization device. Background Technology
[0002] Medical waste refers to contaminated waste produced by hospitals that has come into contact with patients' blood, flesh, etc., such as used cotton balls, gauze, adhesive tape, wastewater, disposable medical instruments, postoperative waste, expired medicines, etc. Because medical waste contains a large number of bacteria, viruses and chemical agents, it has extremely high infectivity, biotoxicity and corrosiveness. Therefore, medical waste usually needs to be crushed by crushing equipment to prevent infection.
[0003] Upon investigation, a Chinese utility model patent discloses a pulverizing device for medical waste recycling and treatment (publication number: CN215917715U), which includes a main body of the device, a pressure roller assembly embedded in the front of the main body of the device, and a feeding assembly installed on the top of the main body of the device.
[0004] In the aforementioned patent, the main body of the device is equipped with a filter screen. Completely pulverized medical waste can be discharged through the filter screen, while incompletely pulverized medical waste is carried up by roller one and roller two for secondary crushing, which effectively improves the pulverization effect of the device. However, there is a certain gap between roller one and roller two and the filter screen. In actual use, incompletely pulverized flaky medical waste may fall onto the filter screen first, causing the filter holes on the filter screen to be blocked. This results in the subsequent completely pulverized medical waste not being able to be discharged through the filter holes in time, reducing the working efficiency of the device.
[0005] Therefore, this utility model provides a medical waste pulverizing device to solve the above problems. Utility Model Content

[0018] 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.
[0019] This utility model provides a medical waste pulverizing device, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a crushing cylinder 1, a discharge trough is provided at the bottom of the crushing cylinder 1, a filter plate 8 is inserted into the discharge trough, a first connecting strip 9 is fixedly connected to the bottom of the filter plate 8, an insert block 10 is fixedly connected to one end of the first connecting strip 9, a crushing mechanism is provided inside the crushing cylinder 1, and a fixing mechanism is provided at the bottom of the crushing cylinder 1.
[0020] The crushing mechanism includes a rotating shaft 2 that passes through a crushing cylinder 1. A crushing blade 5 is fixedly connected to the side surface of the rotating shaft 2. A connecting rod 6 is fixedly connected to the side surface of the rotating shaft 2. A scraper 7 is fixedly connected to the end of the connecting rod 6 away from the rotating shaft 2. A mounting frame 3 is fixedly connected to one side of the crushing cylinder 1. A motor 4 is fixedly connected to one side of the mounting frame 3. The output end of the motor 4 passes through the mounting frame 3 and is fixedly connected to one end of the rotating shaft 2.
[0021] The inner wall of the filter plate 8 is adapted to the inner wall of the crushing cylinder 1. Several filter holes are provided on the filter plate 8. The crushing blade 5 is located inside the crushing cylinder 1. The scraper 7 is attached to the inner wall of the crushing cylinder 1 on the side away from the connecting rod 6.
[0022] The top of the crushing cylinder 1 is fixedly connected to the feed hopper 19, and the bottom of the crushing cylinder 1 is provided with a collection box 18, which is located below the filter plate 8.
[0023] A support 20 is provided at the bottom of the crushing cylinder 1. The inner wall of the support 20 is fixedly connected to the side surface of the crushing cylinder 1. A second connecting strip 21 is fixedly connected to the support 20.
[0024] When in use, medical waste can be thrown into the crushing cylinder 1 through the feed hopper 19. After the medical waste enters the crushing cylinder 1, the motor 4 can be started. When the motor 4 is working, it can drive the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, it will drive the crushing blade 5 to crush the medical waste. At the same time, the connecting rod 6 and the scraper 7 will rotate together with the rotating shaft 2. When the scraper 7 rotates, it can scrape off and knock away the medical waste that has not been completely crushed on the filter plate 8, reducing the possibility of the filter holes being blocked, improving the working efficiency of the device, and also improving the crushing effect of the medical waste. The completely crushed medical waste will fall into the collection box 18 through the filter holes on the filter plate 8, so as to facilitate subsequent processing and collection.
[0025] Furthermore, in order to improve the stability of filter plate 8, such as... Figure 4 , Figure 5 and Figure 6 As shown, the fixing mechanism includes a fixing shell 11. The top of the fixing shell 11 is fixedly connected to the bottom of the crushing cylinder 1. The fixing shell 11 is provided with a slot 12 and a mounting groove 13. The slot 12 is adapted to the insert block 10. The mounting groove 13 is slidably connected to a limiting plate 15. A locking block 16 is fixedly connected to one side of the limiting plate 15, and a spring 14 is fixedly connected to the other side of the limiting plate 15.
[0026] The end of the spring 14 away from the limiting plate 15 is fixedly connected to the inner wall of one side of the mounting groove 13. The insert block 10 is inserted into the inside of the slot 12. The end of the locking block 16 away from the limiting plate 15 extends into the inside of the slot 12. The top of the locking block 16 fits against the bottom of the insert block 10.
[0027] When installing the filter plate 8, the insert block 10 needs to be inserted into the slot 12. When the insert block 10 moves to the top inner wall of the slot 12, the filter plate 8 is installed inside the discharge trough. During the movement of the insert block 10 inside the slot 12, it will contact the arc surface of the locking block 16 and squeeze the locking block 16, causing the locking block 16 to retract into the mounting groove 13. When the locking block 16 moves, it can drive the limiting plate 15 to move. When the limiting plate 15 moves, it can compress the spring 14. When the insert block 10 passes the locking block 16, the spring 14 will release the pressure and push the locking block 16 to move through the limiting plate 15, so that the locking block 16 extends back into the slot 12. At this time, the top surface of the locking block 16 will abut against the bottom of the insert block 10, thereby providing a restraining effect for the filter plate 8 and improving the stability of the filter plate 8.
[0028] Furthermore, to facilitate the disassembly of filter plate 8 by staff, such as... Figure 4 , Figure 5 and Figure 6 As shown, a pull plate 17 is provided at the bottom of the crushing cylinder 1. A handle is fixedly connected to one side of the pull plate 17. One end of the pull plate 17 is inserted into the inside of the mounting groove 13. The locking block 16 passes through the pull plate 17. One side of the pull plate 17 is in contact with the side of the limiting plate 15 near the locking block 16.
[0029] After long-term use, filter plate 8 inevitably needs to be cleaned. When disassembling filter plate 8, the staff can pull the pull plate 17 by the handle. When the pull plate 17 moves, it can drive the limiting plate 15 to move. When the limiting plate 15 moves, it can drive the locking block 16 to retract into the mounting groove 13. At the same time, it can compress the spring 14. When the locking block 16 completely leaves the inside of the mounting groove 13, the insert block 10 loses its restriction. At this time, the filter plate 8 will fall automatically under the influence of gravity, which makes it easy for the staff to disassemble and clean the filter plate 8.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
