Description

Technical Field

[0001] The invention relates to the field of waste treatment, in particular to a non-chemical medical waste incineration treatment device.

[0002] Medical waste, also known as medical waste, refers to the contaminated waste produced by hospitals that has come into contact with patients' blood and flesh, such as used cotton balls, gauze, adhesive tape, waste water, disposable medical instruments, post-operative waste, expired medicines, etc. Medical waste has the characteristics of space pollution, acute infection and latent pollution.

[0003] Unlike domestic waste, medical waste contains a large number of bacteria, viruses and chemicals, and is highly contagious, biotoxic and corrosive. Untreated or incompletely treated medical waste is easily dumped into the ground, which can easily cause pollution to water, soil and air, causing direct or indirect harm to the human body, and may also become the source of epidemics. At present, the treatment of medical waste includes the treatment of chemical medical waste and the treatment of non-chemical medical waste. Chemical medical waste includes discarded chemicals with toxicity, corrosiveness, flammability and explosiveness, such as discarded chemical disinfectants such as peracetic acid and glutaraldehyde, discarded instruments and articles containing heavy metal substances, such as mercury-containing sphygmomanometers, mercury-containing thermometers, and mercury-containing articles used in dentistry, etc. The above chemical medical waste needs to be specially treated. However, in the process of treating non-chemical medical waste, such as some containers or syringes, there is a solution in the waste. In the process of treating such waste, it is necessary to separate the solution from the solid before incineration, so as to improve the safety and environmental protection of non-chemical waste treatment. Therefore, the present invention provides a non-chemical medical waste incineration treatment equipment, which is intended to harmlessly treat non-chemical medical waste. Summary of the invention

[0006] By adopting the above technical scheme, when the non-chemical medical waste incineration treatment equipment of the present invention is used to treat medical waste, the operator first places the waste into the crushing device, and the crushing device crushes the waste to complete the first step of solid-liquid separation. The separated waste residue falls onto the supporting plate through the output end of the crushing device, and the preliminary solid-liquid separation is achieved through the water filter hole.

[0008] By adopting the above technical solution, when the pushing device rotates the medical waste after solid-liquid separation onto the screening plate, the pushing device is required to push the waste.

[0010] By adopting the above technical solution, when the pushing device pushes the waste on the screening sleeve to move, if the crushing device has a low degree of crushing for the medical waste, it will make it difficult for the pushing mechanism to push the waste out of the discharge port, which may easily cause damage to the airbag. Therefore, a trigger device is adopted. When the airbag is pushed to restart, but the second moving plate is stuck and cannot be pushed forward, then at this time, the first moving plate moves in the direction away from the second moving plate as the airbag expands, and abuts against the abutment plate, while driving the abutment plate to rotate in the direction away from the first moving plate, thereby making the first trigger joint and the second trigger joint, and at the same time making the return material pushing device work, so as to push the material to the return material device for secondary crushing, thereby increasing the efficiency of subsequent treatment of medical waste.

[0012] By adopting the above technical scheme, when the return material pushing device pushes the waste material on the screening sleeve, when the pushing cylinder drives the pushing plate to move toward the first moving plate and the second moving plate, the pushing plate drives the driving rod to move in the direction close to the first moving plate and the second moving plate, and because the moving rod and the guide surface side wall opened on the driving rod abut against each other, the moving rod moves in the direction close to the second moving plate, thereby driving the first moving plate to move in the direction of the second moving plate. If there is waste stuck between the first moving plate and the second moving plate, the second moving plate can be pushed in the direction close to the first moving plate, thereby allowing the waste to be pushed out more smoothly by the pushing plate.

[0014] By adopting the above technical solution, by using a solid plate in combination with a screening filter plate, when the solid plate is pulled out, the liquid remaining on the screening plate can be precipitated through the filter holes, further improving the solid-liquid separation capacity of the processing equipment in the present invention.

[0016] By adopting the above technical solution, when the solid plate needs to be pulled out from the screening filter plate, the driving wheel can be driven to rotate through the circulation seal, so that the driving wheel can pull the solid plate out of the shell under the action of friction force, thereby realizing secondary solid-liquid separation of the waste and improving the separation efficiency.

[0017] Optionally, a transposition rod is provided on the side wall of the shell, a transposition motor is provided at the end of the transposition rod away from the shell, a transposition plate is provided at the output end of the transposition motor, a transposition groove is opened on the side wall of the transposition plate, the circulation pipe is inserted in the transposition groove, and when the transposition motor rotates, the transposition plate drives the circulation pipe to cause the driving wheel to rotate in the opposite direction.

[0018] By adopting the above technical solution, in addition to driving the driving wheel to rotate forward, the circulating air outlet changes its position through the shift rod, so that the circulating air outlet can drive the driving wheel to rotate in the opposite direction, so that the solid plate is driven to be inserted into the screening filter plate again for subsequent work processing.

[0023] In summary, the present invention includes at least one of the following beneficial effects: 1.

A crushing device 12 is fixedly installed on the top wall of the shell 13 by bolts, the crushing device 12 is a barrel structure with a hollow interior, a plurality of crushing screws are arranged inside the crushing device 12, a feed inlet is opened on the top wall of the crushing device 12, a feed port is arranged on the bottom wall of the crushing device 12, a feed valve for controlling the feed is arranged on the feed port, the crushing device 12 is located in the positive direction of the shell 13, and a position on the top wall of the shell 13 close to the crushing device 12 is connected to the crushing device 12.

[0028] Reference Figure 1 and Figure 2 A carrying plate 14 is fixedly connected to the inner wall of the shell 13 by bolts. The carrying plate 14 is a rectangular plate structure. A plurality of filter holes are penetrated through the top wall of the carrying plate 14 along the wall thickness direction. The carrying plate 14 is located directly below the feeding port of the crushing device 12. A pushing plate 24 is fixedly connected to the inner wall of the shell 13 by bolts. A pushing structure 2 is arranged on the pushing plate 24. The pushing structure 2 is arranged on one side of the carrying plate 14. The pushing structure 2 includes a first material moving plate 21, a pushing airbag 23 and a second material moving plate 22; a pushing groove 25 is opened on the top wall of the pushing plate 24 in the horizontal direction, and the length direction of the pushing groove 25 is set toward the supporting plate 14, the first material moving plate 21 is inserted into the pushing groove 25, the first material moving plate 21 is slidably connected with the pushing groove 25, the pushing airbag 23 is glued and fixed on the side wall of the first material moving plate 21 close to the supporting plate 14, and the pushing airbag 23 is located above the supporting plate 14, the second material moving plate 22 is glued and fixed to the side of the pushing airbag 23 away from the first material moving plate 21, and the second material moving plate 22 is also slidably connected with the pushing groove 25, a discharge port 16 is opened through the inner side wall of the shell 13, the discharge port 16 is located on the side of the supporting plate 14 away from the pushing structure 2, after the pushing structure 2 pushes the waste out of the discharge port 16, the pushed waste can be incinerated. The side wall of the pushing airbag 23 is connected to the external incineration equipment through a pipeline and a two-way electric valve 62. A discharge port 16 is provided on the side wall of the shell 13. When the pushing structure 2 rotates the medical waste after solid-liquid separation onto the fish carrying plate 14, the pushing structure 2 is required to push the waste. The structure of the pushing airbag 23 can recycle the energy generated by subsequent incineration, which effectively saves energy compared to the traditional cylinder mode.

[0029] Embodiment 2: The difference between Example 2 and Example 1 is that the products after the initial crushing of the solid waste are further screened and crushed for secondary processing.

[0030] Reference Figure 1 and Figure 2 When the non-chemical medical waste incineration treatment equipment in Example 1 is treating medical waste, the crushing device 12 crushes the medical waste so that the medical waste falls onto the supporting plate 14, and the crushed waste is pushed by the pushing structure 2 until the waste is removed. At the same time, the crushed liquid flows out through the filter holes on the supporting plate 14 and falls into the waste liquid tank 11 directly below the shell 13 for subsequent treatment. When the crushed solid matter is subsequently incinerated, if it is not crushed thoroughly, it will make the incineration more difficult, affect the incineration efficiency, and increase energy consumption. Therefore, the discharge port 16 in the present invention is designed with a size of 10cmX100cm. Under this size, if the solid mixture is large in volume after being crushed, it is difficult for the pushing structure 2 to push the fixed mixture out of the discharge port 16. Therefore, Example 2 adds the following structure: Reference Figure 2 and Figure 3 A pushing device 35 is provided on the inner side wall of the housing 13. The pushing device 35 includes a pushing cylinder 41 and a pushing plate 42. The moving direction of the pushing cylinder 41 is perpendicular to the moving direction of the second material moving plate 22. The pushing cylinder 41 is fixed to the inner side wall of the housing 13 by bolts. The pushing plate 42 is fixedly connected to the output end of the pushing cylinder 41 by a flange. The pushing plate 42 is arranged toward the direction of the supporting plate 14. The pushing cylinder 41 drives the pushing plate 42 to push the material on the supporting plate 14 out, so that the material originally stuck at the discharge port 16 can enter the subsequent processing steps.

[0031] Reference Figure 2 and Figure 3A displacement groove 43 is provided on the bottom wall of the carrier plate 14, and the length direction of the displacement groove 43 is consistent with the travel direction of the output end of the push cylinder 41. A driving rod 44 is inserted into the displacement groove 43, and the driving rod 44 is slidably connected with the displacement groove 43. The driving rod 44 is welded and fixed to the side wall of the push plate 42 through a "C"-shaped rod, and the driving rod 44 slides with the displacement groove 43 under the drive of the push rod. A moving groove 46 is provided on the inner side wall of the shift groove 43, and the moving groove 46 is connected to the shift groove 43. A moving rod 45 is inserted in the moving groove 46, and the moving rod 45 is slidably connected to the moving groove 46. The end of the moving rod 45 away from the driving rod 44 is fixedly connected to the second material moving plate 22. A guide surface is provided on the end wall of the driving rod 44 close to the moving rod 45, and the guide surface is inclined in the direction of the moving rod 45. The end wall of the moving rod 45 close to the driving rod 44 abuts against the side wall of the guide surface. When the pushing plate 24 is pushed toward the direction of the supporting plate 14, the driving rod 44 moves into the shift groove 43, thereby causing the moving rod 45 to move in the direction close to the second material moving plate 22, and then causing the second material moving plate 22 to move in the direction close to the first material moving plate 21, so as to contact the waste between the second material moving plate 22 and the discharge port 16, thereby facilitating the pushing plate 42 to push the waste material.

[0032] Reference Figure 2 and Figure 4 A reset opening 3 is provided on the inner wall of the shell 13 along the wall thickness direction. A pair of reset openings 3 are provided, and the pair of reset openings 3 are respectively located on both sides of the first material shifting plate 21. A reset sleeve 31 is fixedly connected to the inner wall of the first reset opening 3. A reset rod 32 is inserted into the reset sleeve 31. The reset rod 32 is slidably connected to the reset sleeve 31. A reset spring 33 is jointly sleeved on the outer side of the reset rod 32 and the reset sleeve 31.

A trigger device 34 is provided on the side wall of the abutment plate away from the second material moving plate 22, and the trigger device 34 includes a first trigger joint 341 and a second trigger joint 342. The first trigger joint 341 is electrically connected to the side wall of the first material moving plate 21 away from the second material moving plate 22, and the second trigger joint 342 is electrically connected to the inner wall of the reset port 3. As the first material moving plate 21 drives the abutment plate to move in the direction away from the second material moving plate 22, the first trigger joint 341 and the second trigger joint 342 abut against each other, and the trigger device 34 is electrically connected to the pushing cylinder 41. When the first trigger joint 341 and the second trigger joint 342 abut against each other, the pushing cylinder 41 starts to work. At the same time, the trigger device 34 is electrically connected to the electric valve 62 on the pushing airbag 23. When the trigger device 34 is started, the pushing airbag 23 no longer continues to inflate, thereby facilitating the pushing cylinder 41 to push the material moving waste that has not been completely crushed.

[0033] Reference Figure 3 and Figure 5The inner wall of the housing 13 is fixedly connected with a screening plate 36, which includes a screening filter plate 51 and a solid plate 52.

[0034] Reference Figure 3 and Figure 5 A solid hole is provided on the inner side wall of the shell 13, and the solid plate 52 extends out of the shell 13 through the solid hole. A driving wheel 6 is rotatably connected to the inner side wall of the shell 13. The cross-section of the driving wheel 6 is gear-shaped, and a rubber strip is provided on the top wall of the tooth peak of the driving wheel 6, and the rubber strip is against the bottom wall of the solid plate 52. A transposition rod 63 is fixedly connected to the side wall of the shell 13 close to the solid plate 52 by bolts, and a transposition motor 64 is fixedly connected to the end of the transposition rod 63 away from the shell 13. The output end of the transposition motor 64 is arranged toward the driving wheel 6, and a transposition piece 65 is provided at the output end of the transposition motor 64. A transposition groove 66 is penetrated on the top wall of the transposition piece 65, and a circulation pipe 61 is fixedly provided in the transposition groove 66. The circulation pipe 61 is connected to the pushing airbag 23, and the circulation pipe 61 is connected to the pushing airbag 23 through an electrically controlled two-way airtight valve, and the output end of the circulation pipe 61 is arranged toward the driving wheel 6. When the solid plate 52 needs to be pulled out from the screening filter plate 51, the driving wheel 6 can be driven to rotate by the circulating seal, so that the driving wheel 6 can pull the solid plate 52 out of the shell 13 under the action of friction. In addition to driving the driving wheel 6 to rotate forward, the circulating air outlet 27 changes its position through the shift rod 63, so that the circulating air outlet 27 can drive the driving wheel 6 to rotate in the opposite direction, so that the solid plate 52 is driven again and inserted into the screening filter plate 51 for subsequent processing.

[0035] Reference Figure 1 and Figure 3A return material port 38 is provided on the side wall of the housing 13, and a return material pusher 38 is fixedly connected to the inner side wall of the housing 13 by bolts. The return material pusher 38 is selected as a cylinder, and the output end of the return material pusher 38 is arranged toward the return material port 38, and the output end of the return material pusher 38 is arranged flush with the screening sleeve 36. The return material device 37 includes a lifting rod 71, a lifting platform 73 and a horizontal return material cylinder 74. The lifting rod 71 is fixed to the side of the return material port 38 away from the return material pusher 38, and the horizontal return material cylinder 74 is installed on the side of the lifting platform 73 away from the housing 13. A return material trough 72 is provided on the side wall of the lifting rod 71 close to the housing 13 along the vertical direction, and the horizontal return material cylinder 74 is slidably connected to the return material trough 72.

A guide groove 75 is provided on the top wall of the lifting platform 73, and the guide groove 75 is provided at the center of the lifting platform 73. A guide slope 76 is also provided on the top wall of the lifting platform 73, and the guide slope 76 is connected to the guide groove 75. A pair of guide slopes 76 are provided, and the pair of guide slopes 76 are inclined toward the guide groove 75. The lifting rod 71 raises the horizontal push cylinder 41 and the lifting platform through the motor, and sends the waste on the lifting platform 73 back to the entrance of the crushing device for crushing. At the same time, when there is unprecipitated liquid on the lifting platform 73, as the lifting platform 73 continues to rise, the liquid is further thrown out from the crushed container during the shaking of the lifting platform 73, and slides along the guide slope 76 into the guide groove 75 to achieve solid-liquid separation.

[0036] The implementation principle of a non-chemical medical waste incineration treatment device in an embodiment of the present invention is as follows: when the non-chemical medical waste incineration treatment device in the present invention is in use, the operator first places the waste into the crushing device 12, and the crushing device 12 crushes the waste to complete the first step of solid-liquid separation. The separated waste residue falls onto the supporting plate 14 through the output end of the crushing device 12, and a preliminary solid-liquid separation is achieved through the water filter hole 15. Then, the pushing structure pushes the waste material so that the waste material is pushed out of the discharge port 16.

[0037] In the process of pushing out the discharge port 16, if the crushing is not thorough, it will make incineration more difficult and affect the incineration efficiency. Therefore, at this time, the size of the discharge port 16 will cause the first material moving plate 21 and the second material moving plate 22 to be stuck. When the airbag 23 is pushed to continue to inflate, but the second material moving plate 22 is stuck and cannot be pushed forward, then at this time, the first material moving plate 21 moves in the direction away from the second material moving plate 22 as the airbag expands, and abuts against the abutment plate, while driving the abutment plate to rotate in the direction away from the first material moving plate 21, thereby making the first trigger joint 341 and the second trigger joint 342, and at the same time making the return material pushing device 38 work, so as to push the material to the return material device 37 for secondary crushing, thereby increasing the efficiency of subsequent treatment of medical waste. At the same time, when the return material pushing device 38 pushes the waste material on the screening sleeve 36, when the pushing cylinder 41 drives the pushing plate 42 to move toward the first material moving plate 21 and the second material moving plate 22, the pushing plate 42 drives the driving rod 44 to move toward the first material moving plate 21 and the second material moving plate 22, and because the moving rod 45 is against the side wall of the guide surface provided on the driving rod 44, the moving rod 45 moves toward the direction close to the second material moving plate 22, thereby driving the first material moving plate 21 to move toward the second material moving plate 22. If there is waste stuck on the first material moving plate 21 and the second material moving plate 22, the second material moving plate 22 can be pushed in the direction close to the first material moving plate 21, so that the waste is pushed onto the screening sleeve 36 more smoothly by the pushing plate 42. When the waste is pushed onto the screening sleeve 36, the exhaust gas of the circulation pipe 61 drives the driving wheel 6 to rotate, so that the solid plate 52 is turned out from the screening filter plate 51, so as to further filter the liquid in the waste; after a period of time, the steering motor drives the steering piece to rotate, and the output end of the circulation pipe 61 is shifted, so that the driving wheel 6 rotates in the opposite direction and the solid plate 52 is reset. The return material pushing device 38 pushes the waste onto the lifting platform 73, and the lifting rod 71 raises the horizontal pushing cylinder 41 and the lifting platform through the motor, and sends the waste on the lifting platform 73 back to the entrance of the crushing device for crushing. At the same time, when there is unprecipitated liquid on the lifting platform 73, as the lifting platform 73 continues to rise, the liquid is further thrown out from the crushed container during the shaking of the lifting platform 73, and slides into the guide groove 75 along the guide slope 76 to achieve solid-liquid separation.

[0038] The non-chemical medical waste incineration treatment equipment of the present invention realizes solid-liquid separation before incineration of medical waste, and the separation degree is higher, which improves the environmental protection level of the equipment during use, and further realizes the harmless treatment of non-chemical medical waste.

[0039] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
