Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment technology, and in particular to a solid-liquid separation device for medical waste treatment. Background Technology

[0002] Medical waste refers to contaminated waste produced by hospitals, such as used cotton balls, gauze, adhesive tape, wastewater, disposable medical instruments, postoperative waste products, expired medicines, and other items that have come into contact with patients' blood, flesh, etc.

[0003] A search revealed a Chinese patent publication number CN217615337U, which discloses a solid-liquid separation device for medical waste treatment. The device includes a housing, inside which a roller is installed. Several drainage holes are formed on the outer wall of the roller. A turntable is rotatably connected to the inner wall of the roller. Multiple driven shafts are rotatably connected to the top of the turntable, arranged in a circular array along the top of the turntable. Each driven shaft has a brush roller mounted on its exterior that abuts against the inner wall of the roller. All driven shafts penetrate the turntable, and a linkage mechanism for driving the multiple driven shafts to rotate is located below the turntable.

[0004] This patent, through the cooperation of various components of the drive mechanism and linkage mechanism, can prevent the drainage holes on the drum from becoming clogged, thereby ensuring the continuity of solid-liquid separation operation. However, after separation, the solid waste needs to be manually removed from the drum, which is time-consuming and labor-intensive, reducing processing efficiency. Utility Model Content

[0028] Example 1

[0029] A solid-liquid separation device for medical waste treatment, such as Figures 1 to 3As shown, the device includes a fixed cylinder 1, a rotating cylinder 2 rotatably connected to the inner wall of the fixed cylinder 1, a certain space between the outer wall of the rotating cylinder 2 and the inner wall of the fixed cylinder 1, a screening hole on the outer wall of the rotating cylinder 2, a connecting cylinder 7 fixed to one end of the inner wall of the fixed cylinder 1, a rotating cylinder 2 rotatably connected to the connecting cylinder 7, and the rotating cylinder 2 and the connecting cylinder 7 communicating with each other, a spiral blade 6 fixed to the inner wall of the rotating cylinder 2, one end of the spiral blade 6 extending into the connecting cylinder 7, a feed hopper 3 provided at one end of the top of the fixed cylinder 1, the bottom end of the feed hopper 3 communicating with the connecting cylinder 7, a gear ring 8 fixedly connected to the outer wall of the rotating cylinder 2, a gear 9 meshing with one side of the outer wall of the gear ring 8, and a rotating motor for driving the gear 9 to rotate installed on the side wall of the fixed cylinder 1.

[0030] The bottom of the fixed cylinder 1, away from the feed hopper 3, is fixedly connected to a guide pipe 4. A support platform 5 is provided below the guide pipe 4. Collection boxes located on both sides of the guide pipe 4 are placed on the support platform 5. Both sides of the bottom end of the guide pipe 4 are provided with discharge ports that are inclined towards the ground. A guide plate 10 is rotatably connected to the inner wall of the guide pipe 4. One end of the guide plate 10 is in contact with the inner wall of the guide pipe 4. A rotating motor that drives the guide plate 10 to rotate is installed on the side wall of the guide pipe 4.

[0031] Waste is fed from the feed hopper 3 into the connecting cylinder 7. The rotating motor drives the gear 9 to rotate, and the rotating cylinder 2 is driven to rotate through the transmission of the gear 9 and the gear ring 8. The spiral blade 6 will rotate with the rotating cylinder 2. The spiral blade 6 will push the waste in the connecting cylinder 7 along the rotating cylinder 2 to the guide pipe 4. After the waste enters the rotating cylinder 2, the liquid waste will flow out of the rotating cylinder 2 from the screening hole, and the solid waste will continue to move to the guide pipe 4. After the solid waste falls from the rotating cylinder 2 into the guide pipe 4, it will be guided by the guide plate 10 and discharged from one of the discharge ports on one side of the guide pipe 4 into a collection box. When the waste in a collection box reaches a certain amount, the rotating motor drives the guide plate 10 to rotate, so that one end of the guide plate 10 contacts the inner wall of the other side of the guide pipe 4, and guides the waste to the other discharge port of the guide pipe 4.

[0032] By incorporating a fixed cylinder 1, a rotating cylinder 2, a spiral blade 6, and a connecting cylinder 7, continuous separation of waste can be achieved without stopping the machine to remove solid waste, thus improving separation efficiency.

[0033] By setting up a guide pipe 4 and a guide plate 10, the two discharge ports can be switched to discharge, which facilitates the replacement of the collection box.

[0034] Example 2

[0035] A solid-liquid separation device for medical waste treatment, this embodiment is based on embodiment 1, with the following improvements, such as... Figures 4 to 6As shown, the support platform 5 includes a fixed frame 11 placed on the ground and two sliding platforms 12. The two sliding platforms 12 are slidably fitted to the top outer wall of the fixed frame 11. The collection box is placed on the top outer wall of the sliding platform 12. A sliding rod 15 is slidably fitted to the inner wall of the fixed frame 11. A rectangular ring 16 is provided in the middle of the sliding rod 15. A turntable 14 is rotatably connected to the inner wall of the fixed frame 11. A protruding rod that slidably fits to the inner wall of the rectangular ring 16 is fixed to the top outer wall of the turntable 14. A drive motor 13 whose output shaft is connected to the turntable 14 is fixed to the top outer wall of the fixed frame 11. Grooves are provided at both ends of the sliding rod 15. An electromagnet 18 is installed on the bottom inner wall of the groove. A connecting block 17 is slidably fitted to the bottom inner wall of the sliding platform 12. The connecting block 17 is connected to the sliding platform 12 by a spring. The connecting block 17 and the electromagnet 18 are magnetically attracted to each other.

[0036] During the separation process, the drive motor 13 drives the turntable 14 to rotate, causing the convex rod to push the rectangular ring 16 to move, and the sliding rod 15 to move back and forth. At the same time, the electromagnet 18 on the side of the discharge port is energized, while the electromagnet 18 on the other end is de-energized, magnetically pulling the connecting block 17 into the groove, so that the sliding rod 15 is connected to a sliding table 12, driving the collection box to move back and forth, so that the waste can be evenly distributed in the collection box and avoid the accumulation of waste. When the waste in the collection box reaches a certain amount, the electromagnet 18 under the collection box is de-energized, stopping the magnetic attraction of the connecting block 17. The spring drives the connecting block 17 to move upward and disengage from the groove. At this time, the sliding rod 15 can no longer drive the sliding table 12 to move. Then, when the electromagnet 18 at the other end of the sliding rod 15 moves to the bottom of the connecting block 17 on the other side, the electromagnet 18 is energized, and the sliding rod 15 is connected to another sliding table 12.

[0037] By setting up the support platform 5, the collection box can be reciprocated, so that the waste can be evenly distributed in the collection box and the waste can be avoided from accumulating.

[0038] Working principle: Waste is fed from the feed hopper 3 into the connecting cylinder 7. The rotating motor drives the gear 9 to rotate, which in turn drives the rotating cylinder 2 through the transmission of the gear 9 and the gear ring 8. The spiral blades 6 rotate with the rotating cylinder 2, pushing the waste in the connecting cylinder 7 along the rotating cylinder 2 into the guide pipe 4. When the waste enters the rotating cylinder 2, the liquid waste flows out of the rotating cylinder 2 through the screening hole, while the solid waste continues to move into the guide pipe 4. After the solid waste falls from the rotating cylinder 2 into the guide pipe 4, it is guided by the guide plate 10 and discharged from one outlet on one side of the guide pipe 4 into a collection box. When the waste in a collection box reaches a certain amount, the rotating motor drives the guide plate 10 to rotate, so that one end of the guide plate 10 contacts the inner wall of the other side of the guide pipe 4, guiding the waste to the other outlet of the guide pipe 4. During the separation process, the drive motor 13 drives the rotating cylinder 7 to rotate. The rotating disc 14 causes the convex rod to push the rectangular ring 16 to move, causing the sliding rod 15 to move back and forth. At the same time, the electromagnet 18 on the side of the discharge port is energized, while the electromagnet 18 on the other end is de-energized. This magnetically pulls the connecting block 17 into the groove, connecting the sliding rod 15 to a sliding table 12, causing the collection box to move back and forth. This allows the waste to be evenly distributed in the collection box, preventing waste accumulation. When the waste in the collection box reaches a certain amount, the electromagnet 18 below the collection box is de-energized, stopping the magnetic attraction to the connecting block 17. The spring causes the connecting block 17 to move upward and disengage from the groove. At this time, the sliding rod 15 can no longer move the sliding table 12. Then, when the electromagnet 18 at the other end of the sliding rod 15 moves to the bottom of the connecting block 17 on the other side, the electromagnet 18 is energized, and the sliding rod 15 is connected to another sliding table 12.

[0039] 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.
