Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment technology, specifically to an incinerator for treating medical waste. Background Technology

[0002] Medical waste refers to waste generated by medical and health institutions during medical treatment, prevention, and health care activities that has direct or indirect infectiousness, toxicity, or other hazards. Because it involves pathogens and other toxic substances, it is generally treated by high-temperature incineration for sterilization and disinfection.

[0003] For example, Chinese Patent Publication No. CN218626864U discloses a medical waste incinerator. This application includes an incinerator, an exhaust pipe, and a purification chamber. The upper surface of the purification chamber has a slot, and a support plate is welded to the inner surface of the purification chamber. A purification tank is slidably connected to the inner surface of the slot. A filter screen is fixedly connected to the lower surface of the purification tank via a fixing rod one, and a water filter plate is fixedly connected to the lower surface of the filter screen via a fixing rod two. The lower surface of the water filter plate abuts against the upper surface of the support plate. The upper surface of the purification tank has holes, and connecting pipes are inserted into the holes. Purification liquid is poured into the purification tank. A smoke exhaust port is located on the front of the purification chamber. The internal purification equipment can be disassembled, so that if the internal purification equipment becomes blocked, the entire equipment does not need to be replaced, thus reducing the later maintenance costs of the device to a certain extent.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can reduce the later maintenance costs to a certain extent, during use, it is necessary to manually shovel out the medical waste incineration residue inside, and the dust raised by the residue will be inhaled by the staff, which will endanger the health of the staff. Therefore, there is an urgent need for an incinerator that can minimize the contact between the staff and the medical waste residue. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: an incinerator for treating medical waste, comprising an incinerator body, a support bracket fixedly installed at the bottom of the incinerator body, a discharge port at the center of the bottom side of the incinerator body, and sliding grooves extending through the bottom of the incinerator body on both sides corresponding to the discharge port. A first opening plate and a second opening plate are slidably inserted into the interior of the two sliding grooves, respectively, and the first opening plate and the second opening plate are abutted against the discharge port. A mechanism for driving the first and second opening plates is provided on the bottom side of the incinerator body. The incinerator body has a trolley for receiving medical waste incineration residue located directly below the feed inlet. The incinerator body incinerates the medical waste. After incineration, the opening and closing transmission assembly drives the opening and closing plates one and two on both sides to separate, thereby opening the feed inlet and allowing the incineration residue to fall into the trolley. This allows the medical waste residue to be collected without contact, avoiding the impact of residue dust on the health of the staff.

[0006] As an optimization, limit rods are fixedly installed on both sides of the first and second opening and closing plates, and the limit rods are cylindrical and tightly slidably connected to both sides of the slide groove. A card plate is fixedly installed on the side of the first opening and closing plate opposite to the second opening and closing plate, and a card slot is opened on the side of the second opening and closing plate opposite to the first opening and closing plate, and the card plate is inserted into the card slot.

[0007] As an optimization, the outer side of the card plate is provided with several rubber strips at equal intervals, and the inner side of the card slot is provided with several sealing grooves, and the rubber strips are tightly embedded in the sealing grooves to further improve the sealing performance.

[0008] As an optimization, the opening and closing transmission assembly includes a slide rail seat fixedly installed on one side of the bottom of the incinerator body. A bidirectional lead screw is rotatably connected inside the slide rail seat. A servo motor for driving the bidirectional lead screw is fixedly installed at one end of the slide rail seat. Two sliders are slidably connected on both sides inside the slide rail seat. The sliders are fixedly installed on the bottom side of one opening and closing plate and the other opening and closing plate, respectively. An L-shaped rod is fixedly installed between the two sliders and the bottom side of the opening and closing plate and the other opening and closing plate.

[0009] As an optimization, two sets of supports are fixedly installed on the other side of the bottom of the incinerator body, and a guide rod is fixedly installed between the two sets of supports. A guide block is slidably sleeved on the outer side of the guide rod, and the two sets of guide blocks are symmetrically mounted on the other bottom side of the opening and closing plate one and the opening and closing plate two, respectively.

[0010] As an optimization, the trolley includes a carriage, casters, and push-pull handles, with the casters fixedly installed at the four corners of the bottom of the carriage and the push-pull handles fixedly installed on both sides of the carriage.

[0011] The beneficial effects of this utility model are: 1. This incinerator for treating medical waste uses a servo motor to drive a bidirectional lead screw to rotate inside the sliders on both sides. This causes the sliders to slide relative to each other along the inner wall of the slide rail, which in turn causes the opening plates 1 and 2 on both sides to separate relative to each other along the inner wall of the slide groove. This opens the discharge port, allowing the incineration residue to fall from the discharge port into the trolley for collection. This allows for the collection of medical waste residue without contact, avoiding the impact of residue dust on the health of workers.

[0012] 2. When the two side opening plates 1 and 2 are connected, the corresponding card plates are inserted into the corresponding slots, which improves the sealing performance of the connection between opening plates 1 and 2. At the same time, the rubber strip is tightly embedded in the sealing groove, which further improves the sealing performance and prevents the medical waste residue dust inside the incinerator from leaking out.

[0015] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0016] 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.

[0017] Please see Figure 1-2 An incinerator for treating medical waste includes an incinerator body 1. A support bracket 2 is fixedly installed at the bottom of the incinerator body 1. A discharge port is opened in the middle of the bottom side of the incinerator body 1. Sliding grooves 3 are opened through the bottom of the incinerator body 1 on both sides corresponding to the discharge port. Opening and closing plates 4 and 5 are slidably inserted into the sliding grooves 3 on both sides, and the opening and closing plates 4 and 5 are connected to block the discharge port. An opening and closing mechanism is provided on the bottom side of the incinerator body 1 for driving the opening and closing plates 4 and 5 to move relative to each other. The transmission assembly includes a trolley 6 located directly below the feed inlet of the incinerator body 1 for receiving incineration residue of medical waste. The incinerator body 1 incinerates the medical waste. After incineration, the opening and closing transmission assembly drives the opening and closing plates 4 and 5 on both sides to separate, thereby opening the feed inlet and allowing the incineration residue to fall into the trolley 6. This allows the medical waste residue to be collected without contact, avoiding the impact of residue dust on the health of the staff. Please see Figure 1-2 Limiting rods 7 are fixedly installed on both sides of the first opening plate 4 and the second opening plate 5. The limiting rods 7 are cylindrical and tightly slidably connected to both sides of the slide groove 3. A retaining plate 8 is fixedly installed on the side of the first opening plate 4 opposite to the second opening plate 5. A retaining groove 9 is opened on the side of the second opening plate 5 opposite to the first opening plate 4. The retaining plate 8 is inserted into the retaining groove 9. When the first opening plate 4 and the second opening plate 5 are connected, the retaining plate 8 will be inserted into the retaining groove 9, thereby improving the sealing performance of the connection between the first opening plate 4 and the second opening plate 5 and preventing residual dust from leaking out. Several rubber strips 10 are equidistantly arranged on the outer side of the retaining plate 8. Several sealing grooves 11 are opened on the inner side of the retaining groove 9. The rubber strips 10 are tightly embedded in the sealing grooves 11, further improving the sealing performance. Please see Figure 3The opening and closing transmission assembly includes a slide rail seat 12 fixedly installed on one side of the bottom of the incinerator body 1. A bidirectional lead screw 13 is rotatably connected inside the slide rail seat 12. A servo motor 14 for driving the bidirectional lead screw 13 is fixedly installed at one end of the slide rail seat 12. Two sliders 15 are slidably connected on both sides inside the slide rail seat 12. The sliders 15 are fixedly installed on the bottom side of one side of the opening and closing plate 4 and the second opening and closing plate 5, respectively. An L-shaped rod 16 is fixedly installed between the two sliders 15 and the bottom side of the opening and closing plate 4 and the second opening and closing plate 5, respectively. By starting the servo motor 14, the bidirectional lead screw 13 will be driven to rotate inside the sliders 15 on both sides, which will then drive the sliders 15 on both sides to slide relative to each other along the inner wall of the slide rail seat 12. Therefore, the opening and closing plates 4 and the second opening and closing plate 5 on both sides will open and close relative to each other. Please see Figure 3 Two sets of supports 17 are fixedly installed on the other side of the bottom of the incinerator body 1. A guide rod 18 is fixedly installed between the two sets of supports 17. A guide block 19 is slidably sleeved on the outer side of the guide rod 18. The two sets of guide blocks 19 are symmetrically mounted on the other bottom side of the opening and closing plate 4 and the opening and closing plate 2 5 respectively. When the opening and closing plate 4 and the opening and closing plate 2 5 slide open and close relative to each other, the guide block 19 will slide along the outer side of the guide rod 18, thereby playing a guiding role and making the opening and closing plate 4 and the opening and closing plate 2 5 open and close stably. Please see Figure 4 The trolley 6 includes a carriage 20, casters 21, and push-pull handles 22. The casters 21 are fixedly installed at the four corners of the bottom of the carriage 20, and the push-pull handles 22 are fixedly installed on both sides of the carriage 20.

[0018] In use, the medical waste is first incinerated in the incinerator body 1. After the incineration is completed, the servo motor 14 is started to drive the bidirectional lead screw 13 to rotate inside the sliders 15 on both sides. This will cause the sliders 15 on both sides to slide relative to each other along the inner wall of the slide rail seat 12. Therefore, the opening and closing plates 4 and 5 on both sides will separate relative to each other along the inner wall of the slide groove 3, which will open the feeding port and allow the incineration residue to fall from the feeding port into the trolley 6 for collection. When the two side opening plates 4 and 5 are connected, the card plate 8 will be inserted into the corresponding slot 9, thereby improving the sealing performance of the connection between the opening plates 4 and 5. At the same time, the rubber strip 10 will be tightly embedded in the sealing groove 11, thereby further improving the sealing performance and preventing the leakage of medical waste residue dust from the incinerator.

[0019] In summary, this incinerator for treating medical waste, by starting the servo motor 14, drives the bidirectional lead screw 13 to rotate inside the sliders 15 on both sides, which in turn causes the sliders 15 to slide relative to each other along the inner wall of the slide rail seat 12. This causes the opening and closing plates 4 and 5 on both sides to separate relative to each other along the inner wall of the slide groove 3, thereby opening the feeding port and allowing the incineration residue to fall from the feeding port into the trolley 6 for collection. This allows for the collection of medical waste residue without contact, avoiding the impact of residue dust on the health of the staff.

[0020] When the two side opening plates 4 and 5 are connected, the card plate 8 will be inserted into the corresponding slot 9, thereby improving the sealing performance of the connection between the two opening plates 4 and 5. At the same time, the rubber strip 10 will be tightly embedded in the sealing groove 11, thereby further improving the sealing performance and preventing the leakage of medical waste residue dust from the incinerator.
