Description

A device and process for the harmless recycling of medical waste through molecular flash dissolution Technical Field

[0001] This invention relates to the field of medical waste treatment technology, and more specifically, to an apparatus and process for the harmless recycling of medical waste through molecular flash dissolution. Background Technology

[0002] Medical waste, also known as medical waste, refers to waste generated during medical treatment, prevention, healthcare, and other related activities that has direct or indirect infectiousness, toxicity, or other hazards.

[0003] Because medical waste contains pathogens, chemical pollutants, and other harmful substances, it is often necessary to treat it in a harmless manner to avoid secondary pollution. Traditional treatment methods are mostly incineration or safe landfill. However, incineration can easily produce harmful gases that pollute the air, and safe landfill can easily cause serious pollution to the land and even groundwater. In order to reduce pollution, the "National Catalogue of Advanced and Applicable Process Technologies and Equipment for Comprehensive Utilization of Industrial Resources (2023 Edition)" mentions molecular flash decomposition technology. This technology rapidly heats organic materials (such as biomass, plastics, rubber, etc.) to high temperatures (usually between 400-800°C) under anaerobic or limited oxygen conditions, causing the organic materials to decompose rapidly into small molecule compounds. The system employs a mirror-distributed two-stage temperature control system, enabling rapid atomization and decomposition of organic solid waste with simultaneous condensation. This effectively improves solid waste treatment efficiency and avoids the coking problem associated with traditional pyrolysis. It also ensures that emissions of pollutants such as dioxins meet standards. To improve flash decomposition efficiency, existing flash decomposition devices typically crush medical waste before flash decomposition. However, existing devices cannot sort the crushed medical waste, which may result in some organic solid waste having excessive metal residues adhering to its surface, preventing rapid heat flash decomposition and severely impacting flash decomposition efficiency. In fact, excessive metal residues can even affect the flash decomposition effect of organic molecules.

[0004] To address the aforementioned issues, some solutions have been proposed in the prior art. For example, Chinese invention patent application CN113546940A discloses a device and process for the harmless recycling of medical waste through molecular flash dissolution. This device, by setting up a sorting mechanism and a recycling mechanism, can facilitate the classification and processing of medical waste of different materials based on their material differences, thereby improving the flash dissolution effect and efficiency. However, in the prior art, when organic solid waste enters the baffle plate, the adapter port lacks a shielding component, which allows some organic solid waste to enter the magnetic powder processing device through the adapter port. Furthermore, when the magnetic powder enters the magnetic powder processing device, some magnetic powder will again fall onto the top wall of the baffle plate through the adapter port, thus seriously affecting the flash dissolution effect. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a device and process for the harmless recycling of medical waste through molecular flash decomposition, which can achieve the effect of medical waste flash decomposition.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A device for the harmless recycling of medical waste by molecular flash dissolution includes a sorting box, wherein a sorting component is provided inside the sorting box;

[0009] Furthermore, the pretreatment component includes a grinding cylinder installed on the top wall of the sorting box, a grinding motor fixedly installed inside the grinding cylinder, and grinding balls installed on the output end of the grinding motor. The grinding cylinder has grinding grooves and grinding holes. A crushing cylinder is installed on the top wall of the grinding cylinder, and a crushing roller is installed inside the crushing cylinder. A molecular flash reactor and a magnetic material processing box are installed on the bottom wall of the sorting box. A solenoid valve is fixedly installed on the partition plate.

[0010] Furthermore, the feeding assembly includes a horizontal plate fixedly installed inside the sorting box. The horizontal plate has a communication port, and the top wall of the horizontal plate is located on an inclined surface that mates with the communication port. The horizontal plate has a horizontal groove, and a sealing rod for sealing the communication port is slidably installed in the horizontal groove. The sealing rod has a communication groove that communicates with the communication port. A second spring is installed between the sealing rod and the horizontal groove. A push block is fixedly installed on the rotating rod, and the side wall of the sealing rod near the push block is an inclined surface.

[0011] Furthermore, a second mounting ring is rotatably mounted on the baffle, a limit ring is fixedly mounted on the baffle, and a return spring is installed between the second mounting ring and the limit ring. A horizontal rod is fixedly mounted on the second mounting ring, and spring telescopic rods are evenly fixedly mounted on the horizontal rod.

[0012] Furthermore, the second mounting ring has a mounting groove, a push rod is slidably mounted in the mounting groove, a third spring is mounted between the push rod and the mounting groove, the second mounting ring has an annular groove, a protrusion that slides with the annular groove is fixedly mounted on the rotating rod, and the end of the push rod near the protrusion is a slope.

[0013] Furthermore, a fourth spring is installed between the partition and the bottom wall of the sorting box, and a linkage block that cooperates with the horizontal rod is uniformly fixed on the top wall of the partition.

[0014] Furthermore, a telescopic tube cooperating with a fourth spring is installed between the partition and the sorting box. An air inlet valve with its input end connected to the outside is fixedly installed on the bottom wall of the sorting box. An exhaust valve is fixedly installed on the bottom wall of the sorting box. A first air pipe is fixedly installed on the output end of the exhaust valve. Brush bristles are evenly fixedly installed on the sorting port. A cavity is opened on the baffle. Air holes cooperating with the brush bristles are evenly opened on the cavity. A control component is provided on the horizontal rod, and the first air pipe is connected to the cavity through the control component.

[0015] Furthermore, the control component includes a connecting hole on a horizontal rod, an air collection groove on the horizontal plate, and the end of the first air pipe away from the exhaust valve is connected to the air collection groove. The air collection groove is provided with a connecting hole that communicates with the connecting hole, and a second air pipe that communicates with the cavity is inserted into the air collection groove.

[0016] Furthermore, a vertical rod is fixedly installed on the horizontal rod, and an elastic rod that cooperates with the vertical rod is fixedly installed on the electromagnet.

[0017] The present invention also provides a process for using the above-mentioned medical waste molecular flash dissolution harmless recycling device, comprising the following steps:

[0018] S1. First, the medical waste is pre-treated, and the pre-treated waste powder will enter the sorting box. At this time, the baffle can block the sorting port to prevent non-magnetic materials from entering the magnetic material processing box. At the same time, when the electromagnet is about to enter the sorting port, the inclined block will first drive the baffle to disengage from the sorting port. After the electromagnet passes through the sorting port, the baffle will block the sorting port again.

[0019] S2. Then, when the rotating rod drives the electromagnet through the sorting box and into the upper part of the partition, the rotating rod will drive the connecting groove and the connecting port through the push block and the sealing rod. At this time, the garbage powder on the horizontal plate can fall down, and the garbage powder will pass through the electromagnet during the process of falling down. At the same time, during the rotation of the rotating rod, the horizontal rod can drive the spring telescopic rod to stir the garbage powder on the top wall of the partition, thereby improving the adsorption effect of the electromagnet on magnetic materials.

[0020] S3. In addition, the rotation of the horizontal bar can cause the partition to shake, which loosens the waste powder on the partition. At the same time, the shaking of the partition can drive the airflow to clean the brush bristles, thereby improving the sorting effect.

[0021] S4. Finally, when the electromagnet is no longer directly above the partition after passing through the sorting port, the electromagnet is de-energized. At this time, the magnetic field of the electromagnet disappears. Then, under the action of gravity, the magnetic material adsorbed on the electromagnet separates from the electromagnet and enters the magnetic material processing box. After the sorting is completed, the solenoid valve is opened, and the non-magnetic material on the top wall of the partition enters the molecular flash reactor through the solenoid valve to carry out the flash reaction.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) This solution can block the sorting port by setting a sealing plate, thereby preventing the garbage powder from falling into the magnetic material processing box through the sorting port when it enters the sorting box. When the electromagnet is about to contact the sorting port, the inclined block can drive the sealing plate to disengage from the sorting port in advance. After the electromagnet disengages from the sorting port, the sealing plate automatically blocks the sorting port, thereby preventing the magnetic powder that has disengaged from the electromagnet from falling back onto the top wall of the partition through the sorting port. This effectively prevents the magnetic material from affecting the flashing effect and improves the flashing effect.

[0024] (2) By setting a sealing rod, when the electromagnet is directly above the partition through the sorting port, the rotating rod will drive the sealing rod to move through the push block and compress the second spring. During the movement of the sealing rod, the connecting groove will be connected to the connecting port. At this time, the waste powder can fall to the top of the partition through the connecting port and the connecting groove. Then, during the process of the waste powder falling, the electromagnet can attract the magnetic material in the waste powder. Since the waste powder is relatively dispersed during the process of falling, the sorting effect of the waste powder can be improved, thereby further avoiding the influence of magnetic material on the flashing effect and further improving the flashing effect.

[0025] (3) This solution uses the cooperation of the protrusion and the push rod. During the rotation of the rotating rod, the protrusion, the push rod and the horizontal rod can drive the spring telescopic rod to swing back and forth, thereby turning over the garbage powder on the top wall of the partition, which facilitates the electromagnet to attract magnetic materials. During the back and forth swing of the horizontal rod, the partition can also be shaken, which further loosens the garbage powder on the top wall of the partition. At the same time, during the shaking of the partition, the airflow can also be driven to clean the brush bristles, thereby improving the sorting effect, effectively avoiding the influence of magnetic materials on the flash dissolution effect, and further improving the flash dissolution effect.

[0046] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0047] Please refer to Figures 1 to 11. A device for the harmless recycling of medical waste by molecular flash dissolution includes a sorting box 1, and a sorting component 2 is provided inside the sorting box 1.

[0048] The sorting assembly 2 includes a baffle 201 fixedly installed inside the sorting box 1. Sorting openings are symmetrically arranged on the baffle 201. A rotating rod 202 is rotatably mounted on the baffle 201. A sorting motor 203, with its output end fixedly connected to the rotating rod 202, is located inside the sorting box 1. A partition 204 is located inside the sorting box 1. A first mounting ring 205 is fixedly mounted on the rotating rod 202. A mounting rod 206 is fixedly mounted on the first mounting ring 205. A mounting section is fixedly mounted on the mounting rod 206. An electromagnet 207 is provided. A sliding groove is provided on the bottom wall of the sorting port. A sealing plate 208 is slidably installed in the sliding groove. A first spring 209 is installed between the bottom wall of the sealing plate 208 and the sliding groove. An inclined block 210 that cooperates with a baffle 201 is fixedly installed on the first mounting ring 205. A groove 211 that cooperates with the inclined block 210 is provided on the baffle 201. A pretreatment component 3 is provided on the top wall of the sorting box 1. A feeding component 4 that cooperates with the baffle 201 is provided inside the sorting box 1.

[0049] The pretreatment component 3 includes a grinding cylinder 301 installed on the top wall of the sorting box 1. A grinding motor 302 is fixedly installed inside the grinding cylinder 301, and a grinding ball 303 is installed on the output end of the grinding motor 302. A grinding groove is opened on the grinding cylinder 301, and a grinding hole 304 is opened on the grinding groove. A crushing cylinder 305 is installed on the top wall of the grinding cylinder 301, and a crushing roller 306 is provided inside the crushing cylinder 305. A molecular flash reactor 307 and a magnetic material processing box 308 are installed on the bottom wall of the sorting box 1. A solenoid valve 309 is fixedly installed on the partition 204.

[0050] In use, medical waste is first poured into the pulverizing cylinder 305, and the pulverizing roller 306 pulverizes the medical waste in the pulverizing cylinder 305. Then, the pulverized medical waste enters the grinding cylinder 301, where the grinding motor 302 drives the grinding balls 303 to grind the pulverized medical waste. The ground medical waste then enters the sorting box 1 through the grinding hole 304 and falls onto the top wall of the partition 204. When the waste powder enters the sorting box 1, the first spring 209 is in an extended state, and the sealing plate 208 seals the sorting port, thereby preventing the waste powder from entering the magnetic material area through the sorting port. The sorting box 308 is used, and then the sorting motor 203 drives the electromagnet 207 to rotate via the rotating rod 202 and the mounting rod 206. During the rotation of the electromagnet 207, magnetic materials can be attracted to its surface. At the same time, during the rotation of the rotating rod 202, the inclined block 210 is driven to rotate along the groove 211 via the first mounting ring 205. When the electromagnet 207 is about to contact the sorting port, the inclined surface of the inclined block 210 contacts the baffle 201 and applies a downward pushing force to the baffle 201. Under the action of the pushing force, the baffle 201 moves downward and squeezes the first spring 209. At this time, the electromagnet 207 can pass through normally. After the electromagnet 207 passes through the sorting port, the inclined block 210 disengages from the baffle 201. At this time, the first spring 209 extends and drives the baffle 201 to block the sorting port. After the baffle 201 blocks the sorting port, the electromagnet 207 is de-energized and its magnetic field disappears. Then, under the action of gravity, the magnetic material on the surface of the electromagnet 207 falls downward and enters the magnetic processing box. When the electromagnet 207 is about to pass through the sorting port again, the inclined block 210 will drive the baffle 201 to move downward again. Then, when the electromagnet 207 passes through the sorting port again, the electromagnet 207 will be energized again. By setting baffle 201, the sorting port can be blocked when medical powder enters the sorting box 1, thereby preventing medical powder from entering the magnetic processing box and affecting the flashing effect of medical powder. When the electromagnet 207 is de-energized and demagnetized, the sorting port can be blocked again, thereby preventing magnetic powder that has detached from the electromagnet 207 from falling back onto the top wall of the partition 204 through the sorting port, effectively preventing excessive magnetic material from affecting the flashing effect. When the sorting is completed, the solenoid valve 309 is opened. At this time, the waste powder on the top wall of the partition 204 enters the molecular flashing reactor 307 through the solenoid valve 309 for flashing, which plays a role in improving the flashing effect.

[0051] As shown in Figures 2, 3, 7, and 8, the feeding assembly 4 includes a horizontal plate 401 fixedly installed inside the sorting box 1. The horizontal plate 401 has a connecting port 402, and the top wall of the horizontal plate 401 is located on the inclined surface that mates with the connecting port 402. The horizontal plate 401 has a horizontal groove, and a sealing rod 403 for sealing the connecting port 402 is slidably installed in the horizontal groove. The sealing rod 403 has a connecting groove 404 that communicates with the connecting port 402. A second spring 405 is installed between the sealing rod 403 and the horizontal groove. A push block 406 is fixedly installed on the rotating rod 202, and the side wall of the sealing rod 403 near the push block 406 is inclined.

[0052] By adopting the above technical solution, the waste powder entering the sorting box 1 will first fall onto the top wall of the horizontal plate 401. Then, when the electromagnet 207 is directly above the partition 204 through the sorting port, the rotating rod 202 will drive the sealing rod 403 to move through the push block 406 and compress the second spring 405. During the movement of the sealing rod 403, the connecting groove 404 will connect with the connecting port 402. At this time, the waste powder can fall above the partition 204 through the connecting port 402 and the connecting groove 404. During the process of the waste powder falling, the electromagnet 207 can attract the magnetic material in the waste powder. Since the waste powder is relatively dispersed during the falling process, the sorting effect of the waste powder can be improved, thereby further avoiding the influence of magnetic material on the flash dissolution effect. At the same time, the waste powder can enter the sorting box 1 intermittently during the sorting process, thereby improving the sorting efficiency and further improving the flash dissolution effect.

[0053] As shown in Figures 4 and 9, a second mounting ring 501 is rotatably mounted on the baffle 201, a limit ring 502 is fixedly mounted on the baffle 201, and a return spring 503 is installed between the second mounting ring 501 and the limit ring 502. A horizontal rod 504 is fixedly mounted on the second mounting ring 501, and spring telescopic rods 505 are evenly fixedly mounted on the horizontal rod 504.

[0054] The second mounting ring 501 has a mounting groove, and a push rod 506 is slidably mounted in the mounting groove. A third spring 507 is installed between the push rod 506 and the mounting groove. The second mounting ring 501 has an annular groove 508. A protrusion 509 that slides with the annular groove 508 is fixedly mounted on the rotating rod 202, and the end of the push rod 506 near the protrusion 509 is a slope.

[0055] By adopting the above technical solution, the rotating rod 202 drives the protrusion 509 to rotate during its rotation. Then, during the rotation of the protrusion 509, it gradually contacts the push rod 506 and drives the push rod 506 to rotate. During the rotation of the push rod 506, the second mounting ring 501, the horizontal rod 504, and the spring telescopic rod 505 rotate. At this time, the return spring 503 begins to store force. During the rotation of the spring telescopic rod 505, the garbage powder on the top wall of the partition 204 can be stirred. When the horizontal rod 504 contacts the baffle 201, the horizontal plate can no longer rotate. At this time, the protrusion 509 applies pressure to the inclined surface of the push rod 506. The push rod 506 moves along the mounting groove and compresses the third spring 507 under the action of the push rod. When the protrusion 509 disengages from the push rod 506, the return spring 503 drives the horizontal rod 504 to return to its original position through the second mounting ring 501. At the same time, the third spring 507 drives the push rod 506 to return to its original position. That is, during the rotation of the rotating rod 202, the spring telescopic rod 505 can be driven to swing intermittently, which can turn over the powder on the top wall of the partition 204, so as to facilitate the electromagnet 207 to adsorb magnetic materials, thereby improving the sorting effect, effectively avoiding the influence of magnetic materials on the flashing effect, and further improving the flashing effect.

[0056] As shown in Figures 3, 7, 8, and 10, a fourth spring 601 is installed between the partition 204 and the bottom wall of the sorting box 1. A connecting block 602 that cooperates with the horizontal rod 504 is uniformly fixed on the top wall of the partition 204.

[0057] A telescopic tube 603, which cooperates with the fourth spring 601, is installed between the partition 204 and the sorting box 1. An air inlet valve 604, whose input end is connected to the outside, is fixedly installed on the bottom wall of the sorting box 1. An exhaust valve 605 is fixedly installed on the bottom wall of the sorting box 1. A first air pipe 606 is fixedly installed on the output end of the exhaust valve 605. Brush bristles 607 are evenly fixedly installed on the sorting port. A cavity 608 is opened on the baffle 201. Air holes 609, which cooperate with the brush bristles 607, are evenly opened on the cavity 608. A control component 7 is provided on the horizontal rod 504, and the first air pipe 606 is connected to the cavity 608 through the control component 7.

[0058] The control component 7 includes a connecting hole 701 on the horizontal rod 504, an air collecting groove 702 on the horizontal plate 401, and the end of the first air pipe 606 away from the exhaust valve 605 is connected to the air collecting groove 702. The air collecting groove 702 is provided with a connecting hole 703 that communicates with the connecting hole 701, and a second air pipe 704 that communicates with the cavity 608 is inserted into the air collecting groove 702.

[0059] By adopting the above technical solution, the horizontal rod 504 gradually comes into contact with the connecting block 602 during rotation and applies a pushing force to the inclined surface of the connecting block 602. Under the action of the pushing force, the connecting block 602 drives the partition 204 to move downward and squeeze the fourth spring 601. When the horizontal rod 504 disengages from the connecting block 602, the fourth spring 601 extends and drives the partition 204 to shake upward. During the shaking of the partition 204, the waste powder on the top wall of the partition 204 can be shaken, thereby making the waste powder on the top wall of the partition 204 loose, which facilitates the electromagnet 207 to adsorb magnetic materials, effectively reducing the influence of magnetic materials on the flashing effect and further improving the flashing effect.

[0060] As the electromagnet 207 moves upwards towards the partition 204 through the sorting port, the brush 607 cleans the residual magnetic material on the surface of the electromagnet 207, effectively preventing the residual magnetic material from falling back onto the top wall of the partition 204. Furthermore, during the vibration of the partition 204, the telescopic tube 603 separates the fourth spring 601 from the waste powder, preventing the waste powder from getting trapped in the fourth spring 601 and thus affecting its normal vibration and the normal entry of the waste powder into the molecular flash reactor 307. During the process of the fourth spring 601 extending and driving the partition 204 to return to its original position, the space between the outer wall of the telescopic tube 603 and the sorting box 1 draws air from the outside through the air inlet valve 604. Then, when the partition 204 moves downward, the airflow is compressed and flows into the cavity 608 through the first air pipe 606 and the control component 7. The airflow is then blown onto the brush bristles 607 through the air holes 609 on the cavity 608, thereby cleaning the magnetic material remaining on the brush bristles 607, further improving the sorting effect, effectively reducing the influence of magnetic material on the flash dissolution effect, and further improving the flash dissolution effect.

[0061] After the airflow passes through the first air pipe 606, it flows into the air collection groove 702, increasing the pressure inside the air collection groove 702. Then, when the horizontal rod 504 drives the connecting groove 404 to connect with the connecting port 402, the connecting hole 701 connects with the connecting hole 703. At this time, the sorting port is blocked. Then, the airflow in the air collection groove 702 flows to the cavity 608 through the connecting hole 703, the connecting hole 701, and the second air pipe 704, and cleans the bristles 607 through the air holes 609 on the cavity 608. This prevents magnetic materials from entering the partition 204 above the sorting port with the airflow, further improving the sorting effect.

[0062] As shown in Figures 3 and 4, a vertical rod 8 is fixedly installed on the horizontal rod 504, and an elastic rod 9 that cooperates with the vertical rod 8 is fixedly installed on the electromagnet 207.

[0063] By adopting the above technical solution, the horizontal rod 504 swings, causing the vertical rod 8 to swing. Then, during the swing of the vertical rod 8, it will hit the elastic rod 9 and cause the elastic rod 9 to vibrate. During the vibration of the elastic rod 9, the vibration can be transmitted to the electromagnet 207, which can shake off the non-magnetic material on the electromagnet 207, further preventing the non-magnetic material from entering the magnetic material processing box 308, and further improving the flash dissolution effect.

[0064] The present invention also provides a process for using the above-mentioned medical waste molecular flash dissolution harmless recycling device, comprising the following steps:

[0065] S1. First, the medical waste is pre-treated, and the pre-treated waste powder will enter the sorting box 1. At this time, the baffle 201 can block the sorting port to prevent non-magnetic materials from entering the magnetic material processing box 308. At the same time, when the electromagnet 207 is about to enter the sorting port, the inclined block 210 will first drive the baffle 201 to disengage from the sorting port. After the electromagnet 207 passes through the sorting port, the baffle 201 will block the sorting port again.

[0066] S2. Then, when the rotating rod 202 drives the electromagnet 207 through the sorting box 1 to enter the partition 204, the rotating rod 202 will drive the connecting groove 404 to the connecting port 402 through the push block 406 and the sealing rod 403. At this time, the garbage powder on the horizontal plate 401 can fall downwards, and the garbage powder will pass through the electromagnet 207 during the downward fall. At the same time, during the rotation of the rotating rod 202, the horizontal rod 504 can drive the spring telescopic rod 505 to stir the garbage powder on the top wall of the partition 204, thereby improving the adsorption effect of the electromagnet 207 on magnetic materials.

[0067] S3. In addition, during the rotation of the horizontal bar 504, the partition 204 can be shaken, which loosens the garbage powder on the partition 204. At the same time, during the shaking of the partition 204, the airflow can be driven to clean the bristles 607, thereby improving the sorting effect.

[0068] S4. Finally, when the electromagnet 207 is no longer directly above the partition 204 after passing through the sorting port, the electromagnet 207 is de-energized. At this time, the magnetic field of the electromagnet 207 disappears. Then, under the action of gravity, the magnetic material adsorbed on the electromagnet 207 is separated from the electromagnet 207 and enters the magnetic material processing box 308. After the sorting is completed, the solenoid valve 309 is opened, and the non-magnetic material on the top wall of the partition 204 enters the molecular flash reactor 307 through the solenoid valve 309 to carry out the flash reaction.
