Description

Technical Field

[0001] This invention relates to the field of medical waste incineration technology, specifically to a high-efficiency, low-emission staged incineration device for medical waste. Background Technology

[0002] Medical waste refers to waste generated by medical and health institutions during medical treatment, prevention, health care and other related activities that has direct or indirect infectiousness, toxicity and other hazards. Direct disposal will cause pollution and hidden dangers. The usual method to deal with this medical waste is to incinerate it directly through an incineration device (incinerator) to kill the medical waste and the viruses or bacteria it carries with high temperature.

[0003] Currently, when existing incinerators are in use, the feed inlet is opened, and medical waste is thrown into the incinerator for incineration. During this process, the flue gas generated by the incinerator will escape from the feed inlet, polluting the surrounding air and affecting the health of the workers. Therefore, the applicant has developed a new technical solution in actual production to solve the above-mentioned technical problems. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a high-efficiency, low-emission medical waste staged incineration device, which has the advantage of reducing the amount of flue gas escaping from the feed inlet.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a high-efficiency, low-emission medical waste tiered incineration device, including an incinerator, a discharge mechanism, a feeding mechanism, and a feed inlet disposed on the incinerator. The discharge mechanism is disposed on the incinerator and communicates with the feed inlet. The discharge mechanism is used to place waste and is equipped with a push plate. The feeding mechanism is disposed on the discharge mechanism and is used to push the push plate to push the waste on the feeding mechanism from the feed inlet into the incinerator. The push plate is equipped with a sealing mechanism for sealing the feed inlet.

[0007] When the feeding mechanism pushes the waste from the feed inlet into the incinerator through the push plate, the push plate opens the sealing mechanism and, through the cooperation of the push plate and the discharge mechanism, prevents the flue gas from escaping from the feed inlet.

[0008] By adopting the above technical solution, when in use, the waste is placed on the feeding mechanism. At this time, the waste is located on the side of the push plate near the feed inlet. Then, the feeding mechanism pushes the push plate closer to the feed inlet. At this time, the push plate will push the waste on the feeding mechanism closer to the feed inlet. When the waste is pushed to the feed inlet, the push plate opens the sealing mechanism. Then, the push plate pushes the waste from the feed inlet into the incinerator. When the push plate feeds the waste from the feed inlet into the incinerator, the waste falls into the incinerator due to gravity. At this time, the waste is located below the push plate, and one side of the push plate is in the incinerator. When the push plate opens the sealing mechanism, the push plate, in cooperation with the feeding mechanism, prevents the flue gas from escaping from the feed inlet.

[0009] After the pusher plate feeds the waste into the incinerator, it moves in the opposite direction. When the pusher plate is aligned with the inner wall of the incinerator, it blocks the feed inlet through a sealing mechanism. After the sealing is completed, the pusher plate continues to move away from the feed inlet until it returns to its original position. Through the above process, the occurrence of flue gas escaping from the feed inlet when the waste enters the incinerator is reduced. It is simple and convenient to use.

[0010] Preferably, the feeding mechanism includes a rectangular cylinder disposed on the incinerator, and the rectangular cylinder is connected to the feed inlet. The top of the rectangular cylinder is provided with a waste placement port, and waste is put into the rectangular cylinder from the waste placement port. The push plate is vertically located in the rectangular cylinder and is located on the side of the waste placement port away from the incinerator.

[0011] The feeding mechanism includes a cover plate disposed on the side of the rectangular cylinder away from the incinerator, and the cover plate closes the opening of the rectangular cylinder. The cover plate is provided with a power source for pushing the push plate to move horizontally.

[0012] Preferably, the sealing mechanism includes a sealing plate and a telescopic mechanism. The sealing plate is located inside the incinerator and abuts against the side of the incinerator where the feed inlet is located. At this time, the sealing plate closes the feed inlet. The push plate is connected to the sealing plate through the telescopic mechanism.

[0013] As the pusher plate approaches the feed inlet and passes the waste disposal outlet, the telescopic mechanism keeps the sealing plate stationary. After the pusher plate approaches the feed inlet and passes the waste disposal outlet, the telescopic mechanism causes the sealing plate to move along with the pusher plate. When the pusher plate moves to the feed inlet and one end of the pusher plate is inside the incinerator, the telescopic mechanism causes the sealing plate to approach the pusher plate until the sealing plate contacts the pusher plate.

[0014] Preferably, the incinerator has a rectangular frame communicating with the feed inlet at one end near the feed inlet, and the sealing plate has a rectangular groove for the rectangular frame to be embedded in.

[0015] Preferably, the telescopic mechanism includes a sliding column disposed on one side of the closed plate, a placement bucket is horizontally disposed on the side of the cover plate away from the rectangular cylinder, the end of the sliding column away from the closed plate extends from the feed inlet to the outside of the incinerator, both the push plate and the cover plate are provided with a connecting groove for the end of the sliding column away from the closed plate to pass horizontally through, and the end of the sliding column passing through the cover plate is horizontally located in the placement bucket, the sliding column is provided with a baffle plate located in the placement bucket, and a compression spring assembly is provided between the baffle plate and the push plate;

[0016] The sliding column is equipped with a connecting component. When the push plate passes the waste placement port, the connecting component automatically connects with the push plate. When the push plate moves to the feed port and one end of the push plate is inside the incinerator, the connection between the connecting component and the push plate is automatically disconnected. At this time, the compression spring assembly causes the sealing plate to approach the push plate until the sealing plate and the push plate come into contact.

[0017] Preferably, the compression spring assembly includes a sleeve, a first compression spring, and a second compression spring. The bottom of the sleeve has a through hole, and the opening of the sleeve has a retaining ring with the inner diameter of the retaining ring matching the through hole. The sleeve is fitted onto the sliding column through the through hole and the retaining ring, and the sleeve is located in the placement barrel between the baffle plate and the push plate. The first compression spring is located between the retaining ring and the baffle plate, and the second compression spring is located between the bottom of the sleeve and the push plate.

[0018] Preferably, the connecting assembly includes a reset mechanism and a slot provided on the arc-shaped wall of the sliding column. The push plate has a placement groove inside, and the placement groove is connected to the connecting groove on the push plate. A sliding plate is slidably connected in the placement groove in the direction away from or towards the connecting groove. A locking block that cooperates with the slot is provided on the side of the sliding plate near the connecting groove. The side of the locking block near the compression spring assembly is an inclined surface. A compression spring is provided on the side of the sliding plate away from the locking block, and the side of the compression spring away from the sliding plate is connected to the groove wall of the placement groove.

[0019] When the push plate passes the waste placement port and the slot corresponds to the connecting slot, the block enters the slot through the compression spring. When the push plate moves to the feed port and one end of the push plate is inside the incinerator, the sliding column is provided with a reset mechanism for pushing the block back into the placement slot.

[0020] Preferably, the reset mechanism includes a sliding groove disposed on the side of the sliding column away from the closed plate, a fixed column is horizontally disposed at the bottom of the placement bucket, the fixed column is located in the sliding groove, the slot is connected to the sliding groove, a long strip groove is horizontally disposed on the arc-shaped wall of the fixed column, and the long strip groove is connected to the slot, the groove wall surface of the long strip groove near the closed plate is a second inclined surface, the bottom end of the card block is provided with a trapezoidal plate that cooperates with the second inclined surface, and one side of the inclined surface on the trapezoidal plate is flush with the first inclined surface.

[0021] Preferably, the slot is located at the bottom end of the arc-shaped wall on the sliding column.

[0022] Preferably, the rectangular tube has a support leg that contacts the ground at the end away from the incinerator.

[0023] The beneficial effects of this invention are as follows: In use, waste is placed on the feeding mechanism, at which time the waste is located on the side of the push plate near the feed inlet. Then, the feeding mechanism pushes the push plate closer to the feed inlet. At this time, the push plate will push the waste on the feeding mechanism closer to the feed inlet. When the waste is pushed to the feed inlet, the push plate opens the sealing mechanism. Then, the push plate pushes the waste from the feed inlet into the incinerator. When the push plate feeds the waste from the feed inlet into the incinerator, the waste falls into the incinerator due to gravity. At this time, the waste is located below the push plate, and one side of the push plate is in the incinerator. When the push plate opens the sealing mechanism, the push plate, in cooperation with the feeding mechanism, prevents the flue gas from escaping from the feed inlet.

[0024] After the pusher plate feeds the waste into the incinerator, it moves in the opposite direction. When the pusher plate is aligned with the inner wall of the incinerator, it blocks the feed inlet through a sealing mechanism. After the sealing is completed, the pusher plate continues to move away from the feed inlet until it returns to its original position. Through the above process, the occurrence of flue gas escaping from the feed inlet when the waste enters the incinerator is reduced. It is simple and convenient to use. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] A high-efficiency, low-emission staged incineration device for medical waste, such as Figure 1 and Figure 2 and Figure 3The system includes an incinerator 1, a discharge mechanism, a feeding mechanism, and a feed inlet 2 on the incinerator 1. The discharge mechanism is located on the incinerator 1 and communicates with the feed inlet 2. The discharge mechanism is used to place waste. A push plate 3 is fitted on the discharge mechanism. The feeding mechanism is located on the discharge mechanism and is used to push the push plate 3 to push the waste on the feeding mechanism from the feed inlet 2 into the incinerator 1. A blocking mechanism is fitted on the push plate 3. The blocking mechanism is used to block the feed inlet 2. When the feeding mechanism pushes the waste from the feed inlet 2 into the incinerator 1 through the push plate 3, the push plate 3 opens the blocking mechanism and, through the cooperation of the push plate 3 and the discharge mechanism, prevents the flue gas from escaping from the feed inlet 2.

[0043] like Figure 1 and Figure 2 and Figure 3 When in use, the waste is placed on the feeding mechanism. At this time, the waste is located on the side of the push plate 3 near the feed inlet 2. Then, the feeding mechanism pushes the push plate 3 closer to the feed inlet 2. At this time, the push plate 3 will push the waste on the feeding mechanism closer to the feed inlet 2. When the waste is pushed to the feed inlet 2, the push plate 3 opens the sealing mechanism. Then, the push plate 3 pushes the waste from the feed inlet 2 into the incinerator 1. When the push plate 3 sends the waste from the feed inlet 2 into the incinerator 1, the waste falls into the incinerator 1 due to gravity. At this time, the waste is located below the push plate 3, and one side of the push plate 3 is in the incinerator 1. When the push plate 3 opens the sealing mechanism, the push plate 3, in cooperation with the feeding mechanism, blocks the flue gas from escaping from the feed inlet 2.

[0044] After the pusher plate 3 feeds the waste into the incinerator 1, the pusher plate 3 moves in the reverse direction. When the pusher plate 3 moves in the reverse direction and its side is flush with the inner wall of the incinerator 1, the pusher plate 3 seals the feed inlet 2 through the sealing mechanism. After sealing, the pusher plate 3 continues to move away from the feed inlet 2 until it returns to its original position (e.g., ...). Figure 3 Through the above process, the occurrence of flue gas escaping from the feed inlet 2 when waste enters the incinerator 1 is reduced, and it is simple and convenient to use.

[0045] like Figure 2 and Figure 3 The feeding mechanism includes a rectangular cylinder 4 horizontally arranged on the incinerator 1, and the rectangular cylinder 4 is connected to the feed inlet 2. The top of the rectangular cylinder 4 is provided with a waste placement port 5. Waste is put into the rectangular cylinder 4 from the waste placement port 5. The push plate 3 is vertically located in the rectangular cylinder 4 and is located on the side of the waste placement port 5 away from the incinerator 1.

[0046] The feeding mechanism includes a cover plate 6 located on the side of the rectangular cylinder 4 away from the incinerator 1, and the cover plate 6 closes the opening of the rectangular cylinder 4. The cover plate 6 is provided with a power source 7 for pushing the push plate 3 to move horizontally. The power source 7 can be an electric cylinder. The end of the rectangular cylinder 4 away from the incinerator 1 is provided with a support leg 32 that contacts the ground.

[0047] like Figure 3 The sealing mechanism includes a sealing plate 8 and a telescopic mechanism. The sealing plate 8 is located inside the incinerator 1 and abuts against the side of the incinerator 1 where the feed inlet 2 is located. At this time, the sealing plate 8 closes the feed inlet 2. The push plate 3 is connected to the sealing plate 8 through the telescopic mechanism.

[0048] As the pusher plate 3 approaches the feed inlet 2 and passes the waste disposal opening 5, the telescopic mechanism keeps the closing plate 8 stationary (e.g., Figure 6 After the pusher plate 3 approaches the feed inlet 2 and passes the waste disposal outlet 5, the pusher plate 3 uses a telescopic mechanism to move the closing plate 8 along with the pusher plate 3 (e.g., Figure 8 When the pusher plate 3 moves to the feed inlet 2, and one end of the pusher plate 3 is inside the incinerator 1 (e.g.) Figure 10 The telescopic mechanism brings the closing plate 8 closer to the push plate 3 until the closing plate 8 abuts against the push plate 3 (e.g., Figure 12 ).

[0049] like Figure 3 The incinerator 1 has a rectangular frame 9 connected to the feed inlet 2 at one end. The sealing plate 8 has a rectangular groove 10 for the rectangular frame 9 to be inserted. The cooperation between the rectangular groove 10 and the rectangular frame 9 reduces the escape of flue gas from the gap between the sealing plate 8 and the incinerator 1 when the sealing plate 8 closes the feed inlet 2. When the sealing plate 8 closes the feed inlet 2, the telescopic mechanism presses the sealing plate 8 against the inner wall of the incinerator 1, further reducing the escape of flue gas from the gap between the sealing plate 8 and the incinerator 1.

[0050] like Figure 2 and Figure 3 and Figure 5 The telescopic mechanism includes a sliding column 12 horizontally arranged on one side of the closed plate 8, and a placement bucket 13 horizontally arranged on the side of the cover plate 6 away from the rectangular tube 4. The end of the sliding column 12 away from the closed plate 8 extends from the feed inlet 2 to the outside of the incinerator 1. Both the push plate 3 and the cover plate 6 are provided with a connecting groove 14 for the end of the sliding column 12 away from the closed plate 8 to pass through horizontally. The end of the sliding column 12 passing through the cover plate 6 is horizontally located in the placement bucket 13. The sliding column 12 is provided with a baffle 15 located in the placement bucket 13, and a compression spring assembly is provided between the baffle 15 and the push plate 3.

[0051] The sliding column 12 is equipped with a connecting component. When the push plate 3 passes the waste placement port 5, the connecting component automatically connects with the push plate 3. When the push plate 3 moves to the feed port 2 and one end of the push plate 3 is inside the incinerator 1, the connection between the connecting component and the push plate 3 is automatically disconnected. At this time, the compression spring assembly causes the sealing plate 8 to approach the push plate 3 until the sealing plate 8 and the push plate 3 come into contact. The number of sliding columns 12 and placement buckets 13 can be two, and the two sliding columns 12 will not affect the push plate 3 from pushing the waste.

[0052] like Figure 3 and Figure 5 and Figure 6 The compression spring assembly includes a sleeve 16, a compression spring 17, and a compression spring 18. The bottom of the sleeve 16 has a through hole 19, and the opening of the sleeve 16 has a retaining ring 20, the inner diameter of which is the same as that of the through hole 19. The sleeve 16 is fitted onto the sliding column 12 through the through hole 19 and the retaining ring 20. The sleeve 16 is located in the placement barrel 13 and between the baffle plate 15 and the push plate 3. The compression spring 17 is located between the retaining ring 20 and the baffle plate 15, and the compression spring 18 is located between the bottom of the sleeve 16 and the push plate 3. The diameter of the connecting groove 14 on the push plate 3 is F, and the diameter of the connecting groove 14 on the cover plate 6 is F1, where F1 is greater than F. The outer diameter of the retaining ring 20 is F2, where F2 is less than F1. The compression spring 17 and the compression spring 18 are always in a compressed state.

[0053] like Figure 3 and Figure 5 The connecting components include a reset mechanism and a slot 21 provided on the arc-shaped wall of the slide column 12. The push plate 3 has a placement slot 22 inside, and the placement slot 22 is connected to the connecting slot 14 on the push plate 3. A slide plate 23 is slidably connected in the placement slot 22 in the direction away from or close to the connecting slot 14. A block 24 that cooperates with the slot 21 is provided on the side of the slide plate 23 close to the connecting slot 14. The side of the block 24 close to the compression spring assembly is a slope 25. A compression spring 26 is provided on the side of the slide plate 23 away from the block 24, and the side of the compression spring 26 away from the slide plate 23 is connected to the groove wall of the placement slot 22.

[0054] When the push plate 3 passes the waste placement port 5 and the slot 21 corresponds to the connecting slot 14, the locking block 24 enters the slot 21 through the compression spring 26 (as shown). Figure 6 and Figure 7 When the pusher plate 3 moves to the feed inlet 2 and one end of the pusher plate 3 is located inside the incinerator 1, the slide column 12 is provided with a reset mechanism for pushing the card block 24 back to the placement groove 22. The card groove 21 is located at the bottom end of the arc-shaped wall on the slide column 12.

[0055] like Figure 6 and Figure 7 The reset mechanism includes a sliding groove 27 located on the side of the sliding column 12 away from the closed plate 8. A fixed column 28 is horizontally provided at the bottom of the barrel 13. The fixed column 28 is located in the sliding groove 27. The slot 21 is connected to the sliding groove 27. A long strip groove 29 is horizontally provided on the arc-shaped wall of the fixed column 28. The long strip groove 29 is connected to the slot 21. The groove wall surface of the long strip groove 29 near the closed plate 8 is a second inclined surface 30. The bottom end of the locking block 24 is provided with a trapezoidal plate 31 that cooperates with the second inclined surface 30. One side of the inclined surface on the trapezoidal plate 31 is flush with the first inclined surface 25.

[0056] The procedure for using this device is as follows:

[0057] The first step is to put the waste into the rectangular tube 4 through the waste placement port 5.

[0058] In the second step, the power source 7 horizontally pushes the push plate 3 closer to the feed inlet 2. The push plate 3 contacts the waste and pulls the waste closer to the feed inlet 2. At this time, the compression spring 17 and the compression spring 28 extend. When the push plate 3 passes the waste placement opening 5 and the slot 21 corresponds to the placement slot 22, the compression spring 36 will push the slide plate 23 closer to the slot 21 until the block 24 enters the slot 21. At this time, the trapezoidal plate 31 on the block 24 passes through the slot 21 and is located in the elongated slot 29 (e.g., Figure 6 and Figure 7 Then, as the push plate 3 approaches the feed inlet 2, the side of the locking block 24 away from the inclined plane 25 will contact the groove wall of the slot 21. At this time, the push plate 3 will drive the sliding column 12 to move through the cooperation of the locking block 24 and the slot 21. At this time, the compression spring 17 and the compression spring 18 stop extending, and the sealing plate 8, the baffle 15, the sliding column 12, the compression spring 17 and the compression spring 18 will move with the push plate 3 through the sliding column 12, thereby releasing the sealing plate 8 from blocking the feed inlet 2 (e.g., Figure 8 ).

[0059] Thirdly, as the pusher plate 3 approaches the feed inlet 2, when the pusher plate 3 moves to the feed inlet 2, the waste pushed by the pusher plate 3 will fall into the incinerator 1 due to gravity. At this time, the waste is located below the pusher plate 3 and the closing plate 8, and one inclined surface of the trapezoidal plate 31 will contact the inclined surface 30 of the elongated groove 29 (e.g., Figure 8 and Figure 9 Then, push plate 3 continues to move into incinerator 1. At this time, inclined surface 30 will press trapezoidal plate 31 towards placement groove 22. When the side of push plate 3 near closing plate 8 is in incinerator 1, locking block 24 will separate from groove 21, and one inclined surface on trapezoidal plate 31 will correspond to the groove wall of groove 21 (e.g., Figure 10 and Figure 11 At this point, the push plate 3 stops moving, and the compression springs 17 and 18 extend again, pushing the baffle 15 away from the feed inlet 2. The baffle 15 then pulls the sealing plate 8 closer to the push plate 3 via the sliding column 12, until the sealing plate 8 contacts the push plate 3 (e.g., ...). Figure 12 and Figure 13 As the sliding column 12 pulls the closing plate 8 closer to the push plate 3, one side of the groove wall of the slot 21 on the sliding column 12 will continue to press the trapezoidal plate 31 in the direction of the slot 22 through one side of the inclined surface on the trapezoidal plate 31 (e.g. Figure 11 The fixed column 28 will not move throughout the entire process until the trapezoidal plate 31 is completely in the placement slot 22.

[0060] Step four, as Figure 12Power source 7 horizontally pushes push plate 3 to move in the opposite direction. At this time, sealing plate 8, baffle 15, compression spring 17, and compression spring 2 18 will move with push plate 3. When sealing plate 8 contacts the inner wall of incinerator 1, push plate 3 continues to move in the opposite direction. At this time, sealing plate 8 and push plate 3 will separate, and compression spring 17 and compression spring 2 18 will begin to compress as sealing plate 8 separates from push plate 3. At this time, sealing plate 8 will abut against the inner wall of incinerator 1 (e.g., Figure 6 ), until the push plate 3 moves to the side of the waste placement opening 5 away from the incinerator 1 (e.g. Figure 3 ), so that it can be used next time;

[0061] like Figure 6 and Figure 7 During the reverse movement of the push plate 3, the push plate 3 will pass through the slot 21. When the push plate 3 passes through the slot 21, the compression spring 26 will push the slide plate 23 closer to the slot 21 until the block 24 enters the slot 21. At this time, the trapezoidal plate 31 on the block 24 passes through the slot 21 and is located in the elongated groove 29. Then, as the push plate 3 moves away from the feed inlet 2, since one side of the inclined surface on the trapezoidal plate 31 is flush with the inclined surface 25, the block 24 can be squeezed into the placement groove 22 again through the cooperation of the slot 21, the inclined surface 25 and the trapezoidal plate 31. At this time, the slot 21 and the block 24 will not affect the push plate 3 moving away from the feed inlet 2. Through the above process, the occurrence of flue gas escaping from the feed inlet 2 when waste enters the incinerator 1 can be reduced. It is simple and convenient to use.

[0062] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
