Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0019] Please see Figures 1-5A flue gas treatment device for a continuous pyrolysis treatment process of medical waste includes a treatment box 1, a negative pressure component, and a filter component. The treatment box 1 has a treatment chamber inside, and a feeding port communicating with the treatment chamber is provided on the front of the treatment box 1. A sealing door 2 is also provided on the front of the treatment box 1 to close the feeding port. The negative pressure component includes a support frame 3, a partition 4, a connecting pipe 5, a fan 6, and a diversion pipe 19. Two sets of connecting pipes 5 communicating with the treatment chamber are provided on the bottom wall of the support frame 3. A filter chamber is provided inside the support frame 3, and a partition 4 is provided in the middle part of the filter chamber. The partition 4 is positioned between the two sets of connecting pipes 5, and the filter chamber is penetrated above the connecting pipes 5. A fan 6 is also provided on the support frame 3, and a diversion pipe 19 with a downward opening (U-shape) is also provided on the support frame 3. The two free ends of the diversion pipe 19 communicate with the filter chamber, and the input end of the fan 6 is connected to the output end of the diversion pipe 19. When the closed door 2 on the front of the treatment box 1 is closed, the treatment box 1 processes the material in the treatment chamber. The fan 6 on the support frame 3 is started. The input end of the fan 6 forms a negative pressure channel through the lower opening C-shaped diverter pipe 19. This negative pressure is transmitted to the filter chamber through the diverter pipe 19, and then acts on the treatment chamber through the connecting pipe 5. This provides stable power for the subsequent exhaust gas to flow from the treatment chamber to the filter chamber and finally enter the fan 6, ensuring that the exhaust gas flows along the preset path throughout the process without stagnation or leakage. In this embodiment, a switch valve 10 is also provided on the connecting pipe 5. When the switch valves 10 of the two sets of connecting pipes 5 are opened, the exhaust gas (containing HCl, particulate matter, and organic pollutants) in the treatment chamber rises synchronously through the two sets of connecting pipes 5 and enters the filter chamber of the support frame 3. The partition 4 in the middle of the filter chamber divides the exhaust gas into two paths (corresponding to the two sets of connecting pipes 5 respectively). The filter assembly includes a sliding frame 7, a handle 8, and a fixing component. The left and right sides of the front of the support frame 3 are symmetrically provided with sliding grooves that are adapted to the sliding frame 7. The front of the sliding frame 7 is also provided with a C-shaped handle 8. The two free ends of the handle 8 are connected to the sliding frame 7. The sliding frame 7 is also provided with a fixing component that is connected to the support frame 3. The middle part of the sliding frame 7 is embedded with a filter screen 9 to avoid the exhaust gas from concentrating and impacting one side of the filter screen 9, and to ensure that the load of each area of ​​the filter screen 9 is uniform.

[0020] Close the switch valve 10 of the blocked side connecting pipe 5 (if the left side filter screen 9 is blocked, close the switch valve 10 of the left side connecting pipe 5). At this time, no waste gas enters the left side filter chamber, while the right side connecting pipe 5 continues to intake air normally, and the right side filter screen 9 continues to filter waste gas—ensuring that the waste gas generated by the pyrolysis of medical waste is purified without interruption and ensuring continuous operation of the equipment.

[0021] In this embodiment, the fixing component includes a handle 11, a worm gear 12, a worm 13, a screw 14, and a plug 15. A movable cavity is provided in the middle of the front of the sliding frame 7, and the worm 13 and worm gear 12 are disposed within the movable cavity. The worm 13 meshes with the worm gear 12. Receiving grooves are symmetrically arranged on the left and right sides of the sliding frame 7. Screws 14 are symmetrically arranged on the left and right sides of the center of the worm gear 12. A plug 15 is disposed within each receiving groove, and the corresponding screw 14 extends into the corresponding receiving groove and engages with the plug 15. The support frame 3 is provided with a slot that matches the other end of the insert 15. The worm gear 13 passes through the slide frame 7 and is connected to the handle 11. Rotating the handle 11 on the front of the slide frame 7 unlocks the slide frame 7 through the worm gear 12 and worm 13. The insert 15 is threadedly connected to the screw 14 and retracts along the receiving groove as the screw 14 rotates (disengaging from the slot of the support frame 3), thus releasing the lock between the slide frame 7 and the support frame 3. The side of the insert 15 near the corresponding slot is rounded to ensure ease of assembly. Hold the C-shaped handle 8 and pull the slide frame 7 outward along the slide groove of the support frame 3. The slide frame 7 will move the filter screen 9 embedded in the middle out of the filter chamber at the same time. At this time, the filter screen 9 can be cleaned or replaced directly.

[0022] The friction ring 18 at the end of the slide frame 7 near the handle 11 is in close contact with the slide groove, so there is no jamming during the pulling process. At the same time, it prevents unfiltered exhaust gas from leaking from the gap of the slide groove, ensuring operational safety.

[0023] In this embodiment, the handle 11 is disposed between the two free ends of the handle 8, and an eccentric block 16 is also provided on the front of the handle 11 to indicate the angle of rotation of the handle 11, thereby facilitating the understanding of the state of the insert 15.

[0024] In this embodiment, friction texture 17 is provided around the handle 11 to ensure the stability of the drive handle 11.

[0025] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
