Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, and in particular to an integrated medical waste treatment device. Background Art

[0002] Medical waste refers to waste that is directly or indirectly infectious, toxic or otherwise hazardous and is generated by medical institutions in the course of medical treatment, prevention, health care and other related activities. It specifically includes infectious, pathological, damaging, drug and chemical wastes. These wastes contain a large number of bacteria and viruses, and have certain characteristics of spatial pollution, acute viral infection and latent infection. If they are not managed strictly and discarded at will, and allowed to mix with domestic waste and spread into people's living environment, they will pollute the atmosphere, water sources, land, animals and plants, cause the spread of diseases, and seriously endanger people's physical and mental health.

[0003] In the prior art, such as Chinese patent publication number CN112696691A, a medical waste treatment device is disclosed, which relates to the technical field of medical waste treatment, and solves the problems of single sterilization and disinfection function of the device, incomplete incineration and gas leakage. A medical waste treatment device includes a main body, a first crushing mechanism drives a first crushing knife and a second crushing knife to move back and forth horizontally through a first cylindrical cam and a second cylindrical cam, and the first crushing knife and the second crushing knife approach or move away from each other to crush the medical waste, and the crushed medical waste passes through the screen from the crushing chamber into the sterilization and disinfection chamber and is crushed again by the second crushing mechanism, the spraying mechanism sends the medicine into the sterilization and disinfection chamber and cooperates with the ultraviolet sterilization lamp to sterilize and disinfect the medical waste, and under the action of the induced draft fan, the air is sent to the gas treatment device for treatment without leakage, and has the advantages of good sterilization and disinfection effect, thorough incineration and low gas leakage.

[0004] Although the above patent solves the problems of single sterilization and disinfection function, incomplete incineration and gas leakage of the device, the existing medical waste treatment device mainly completes the incineration treatment of medical waste in an independent chamber. After completing the incineration treatment of a batch of waste, this treatment method requires opening the entire chamber to discharge slag and feed the next batch of waste. In this process, the next batch of waste will need to be re-burned at room temperature, and more heat is required to re-heat and incinerate from a low temperature state, resulting in a large amount of energy waste.

[0005] Therefore, an integrated medical waste treatment device is proposed to solve the problems raised in the above background technology. Summary of the invention

[0006] The purpose of the present invention is to provide an integrated medical waste treatment device to solve the problem that the existing medical waste treatment devices mentioned in the above background technology will cause a large amount of energy waste when incinerating medical waste.

[0008] Preferably, the outer circular shell, the inner circular shell, the annular bottom and the annular cover form a closed channel, the partition is used to divide the interior of the closed channel into four processing spaces, a shovel plate is fixedly connected to the outer surface of the partition near the bottom, the bottom of the shovel plate and the top of the annular bottom are slidably fitted, a feeding port is provided on the top of the annular cover, two installation ports are provided on the bottom of the annular cover in a clockwise direction of the feeding port, a unloading port is provided on the bottom of the annular cover in a counterclockwise direction of the feeding port, and the flamethrower end passes through the inner circular shell.

[0009] By adopting the above technical scheme, the closed channel composed of the outer circular shell, the inner circular shell and the annular cover is divided into four processing spaces by the partition. The four processing spaces are divided into the feeding bin, the drying bin, the combustion bin and the discharge bin in a clockwise direction. This device mainly incinerates biomass waste such as medical bandages, cotton balls and cotton swabs, and the main shell needs to select high-temperature resistant materials according to actual conditions.

[0011] By adopting the above technical solution, the reduction gear set consists of a compound gear and a pinion, which is used to transmit the driving force of the servo motor to the teeth, thereby driving the rotating ring to rotate. The reduction gear set has the effect of reducing speed and increasing torque.

[0012] Preferably, the installation shell is fixedly connected between the inner walls of one of the installation ports. A plurality of blocking blocks are fixedly connected to the inner bottom of the installation shell. A support plate is arranged above the installation shell. One side of the support plate is bent downward. A plurality of arc-shaped grooves corresponding to the size of the blocking blocks are formed on the outer surface of the support plate. The tops of the blocking blocks, the top of the installation shell, and the top of the annular bottom are in a horizontal state.

[0013] By adopting the above technical solution, one side of the support plate is bent. The shovel plate passing through in the clockwise direction will press the curved surface of the support plate, causing it to gradually descend. After the support plate descends, the arc-shaped grooves on its surface will be blocked by the blocking blocks.

[0014] Preferably, a plurality of through rods are fixedly connected to the bottom of the support plate. A flow dividing shell is installed at the bottom of the installation shell. A plurality of circular sleeves are embedded in the top of the flow dividing shell. The bottom ends of the through rods slide through the bottom of the installation shell and extend into the interior of the circular sleeves. A spring is fixedly connected between the inner bottom of the circular sleeve and the bottom end of the through rod. An air inlet pipe is fixedly communicated with the bottom of the flow dividing shell.

[0015] By adopting the above technical solution, the through rods cooperate with the circular sleeves inside the flow dividing shell to limit the support plate, enabling it to move up and down within a certain stroke. The resilience provided by the spring can push the support plate upward when the pressure above it is lost. Moreover, the spring and the combustion chamber are blocked by the installation shell, which can reduce the high-temperature resistance requirements for the spring and improve the service life of the spring.

[0016] Preferably, the first blower is fixedly installed at the bottom of the flow dividing shell through a bracket, and the air outlet of the first blower is fixedly communicated with the air inlet pipe. The air inlet of the first blower is fixedly communicated with an upward-extending first connecting pipe. The upper end of the first connecting pipe is fixedly communicated with a hollow shell. The hollow shell is fixedly installed on the top of the annular cover and is symmetrically located with respect to the feeding port.

[0017] By adopting the above technical solution, after the first blower is started, the external air will first enter the interior of the hollow shell and be heated, thereby improving the combustion-supporting effect.

[0018] Preferably, the interior of the hollow shell is hollow, and an opening is provided on one side away from the first connecting pipe. The top of the hollow shell is fixedly communicated with a second connecting pipe. The second connecting pipe is in a communicating state with the annular cover. The outer surface of the second connecting pipe passes through from above the inner circular shell and extends downward. The heating plate is fixedly connected between the inner walls of another installation port. The lower end of the second connecting pipe penetrates through the bottom of the heating plate and extends upward. The heating plate is located in the clockwise direction of the feeding port.

[0019] By adopting the above technical solution, a channel is provided inside the hollow shell, and a circular opening is also provided at the corresponding position on the top of the annular cover for connecting the bottom end of the second connecting pipe and the inside of the combustion chamber. When the air supports combustion inside the combustion chamber, high-temperature gas will be formed along with the flue gas and enter the drying chamber inside the device from the inside of the second connecting pipe, so that the moisture in the medical waste inside the drying chamber is evaporated, and it has the effect of high-temperature sterilization, improving the subsequent combustion efficiency.

[0020] Preferably, the housing is fixedly installed on the top of the annular cover. An inner liner is fixedly connected to the inner side of the housing. Openings are provided at both the upper and lower ends of the inner liner. The bottom of the inner liner is in communication with the top of the annular cover. A plurality of through holes are arranged in a row on the outer surface of the inner liner near the inner top of the housing. A spiral piece is fixedly connected between the outer surface of the inner liner and the inner wall of the housing near the lower part.

[0021] By adopting the above technical solution, the through holes are used to connect the internal space of the housing and the internal space of the inner liner. The design of the spiral piece makes a spiral channel formed between the housing and the inner liner. The high-temperature air inside the drying chamber will enter from below the inner liner and discharge from above after treating the medical waste.

[0022] Preferably, a second blower is installed at a position near the bottom of the outer surface of the housing. The upper end of the inner liner extends above the housing. A filter cover is sleeved on the top end of the inner liner. An igniter is installed on the top of the housing. The ignition end of the igniter penetrates through the outer surface of the inner liner and extends to the other side.

[0023] By adopting the above technical solution, the second blower is used to send external air into the housing. When the medical waste inside the drying chamber undergoes high-temperature pyrolysis, combustible smoke and gas will be generated. At the same time, after the high-temperature air passes through the drying chamber, a certain amount of heat will remain. And under the action of the heating plate, the air entering the inner liner from the drying chamber is at a relatively high temperature. At this time, the air in the spiral channel inside the housing will form high-temperature air through heat exchange and enter the inside of the inner liner from the through holes.

[0024] Preferably, the receiving cover is fixedly connected to the bottom of the annular bottom and the top of the receiving cover is in communication with the material discharging port. A feeding pipe is fixedly communicated with the outer surface of the receiving cover near the bottom. One end of the feeding pipe is fixedly connected with a driving motor. A screw blade is rotatably connected inside the feeding pipe. The output end of the driving motor rotatably penetrates through the outer surface of the feeding pipe and is fixedly connected with the screw blade.

[0025] By adopting the above technical solution, the receiving cover is used to receive the ash residue falling from the material discharging port. The driving motor is used to drive the screw blade to rotate, thereby conveying the dust residue outwards from the inside of the feeding pipe.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention is in use, the interior of the device is designed as a feeding bin, a drying bin, a combustion bin and a discharging bin. Biomass medical waste such as gauze is put into the feeding port, and the partition plate is driven to rotate by a servo motor, a reduction gear set and a rotating ring. The waste is processed in each bin in turn. With the integrated design, the interior is in a relatively closed state. When the biomass medical waste is put into the device for incineration, the generated heat can preheat the combustion-supporting air, improving the combustion-supporting effect. At the same time, the next batch of medical waste can be treated at high temperature, reducing the heat required for combustion and having a good energy-saving effect.

[0027] 2. When the present invention is in use, while the high-temperature flue gas generated by combustion cooperates with the heating plate to perform high-temperature treatment on the medical waste inside the drying bin, after the medical waste undergoes high-temperature pyrolysis, combustible smoke and gas are generated and flow into the upper inner tank along with hot air. The second blower sends external air into the inside of the housing, heats it through heat exchange, and then passes through the through holes and mixes with the combustible smoke and gas. At this time, under the action of the igniter, the flue gas mixture will be combusted for the second time, so that substances such as unburned carbon black particles and carbon monoxide in the flue gas can be completely burned, presenting a smokeless state, avoiding environmental pollution caused by the flue gas generated after incinerating medical waste, and improving the incineration treatment effect of medical waste.

[0028] 3. When the present invention is in use, when the ashes generated inside the combustion bin are pushed by the shovel plate and the partition plate and pass through the feeding port, they will fall into the lower receiving cover, and will gather at the lower position inside the receiving cover under the action of gravity. At this time, a collecting container is fixedly sealed at the outer end of the feeding pipe, and the driving motor is started to drive the auger blade to rotate. At this time, under the action of the auger blade, the ashes can be stably conveyed into the collecting container, and the entire slag discharge path is in a relatively closed state, and the slag discharge and conveying process is stable, thus effectively avoiding the problem of environmental pollution caused by the dispersion of ashes and having a good environmental protection effect.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1-9As shown in the figure, the present invention provides a technical solution: an integrated medical waste treatment device, including a box body assembly 1. An overhead assembly 2 is arranged inside the box body assembly 1. A gas supply assembly 3 is arranged outside the box body assembly 1 near the overhead assembly 2. A secondary combustion assembly 4 is arranged at the top of the box body assembly 1. A discharge assembly 5 is arranged at the bottom of the box body assembly 1. The box body assembly 1 is used to accommodate and process medical waste, including an outer circular shell 101 and an inner circular shell 115. An annular bottom 114 is fixedly connected between the bottoms of the outer circular shell 101 and the inner circular shell 115. An annular cover 108 is fixedly connected between the tops of the outer circular shell 101 and the inner circular shell 115. A rotating ring 104 is rotatably connected to the inner surface of the outer circular shell 101 through a bearing. Four partition plates 106 are equidistantly and fixedly connected to the inner surface of the rotating ring 104. The inner surface of the partition plate 106 is in contact with the outer surface of the inner circular shell 115. A flamethrower 109 is installed on the inner surface of the inner circular shell 115. The overhead assembly 2 is used to support the medical waste away from the annular bottom 114, including a mounting shell 203. The gas supply assembly 3 includes a first blower 301 and a heating plate 305. The secondary combustion assembly 4 is used to process the flue gas, including a housing 401. The discharge assembly 5 is used to stably discharge the combustion products, including a receiving cover 501.

[0033] The outer circular shell 101, the inner circular shell 115, the annular bottom 114 and the annular cover 108 form a closed channel. The partition plate 106 is used to divide the inside of the closed channel into four treatment spaces. A shovel plate 107 is fixedly connected to the outer surface of the partition plate 106 near the bottom. The bottom of the shovel plate 107 is in sliding contact with the top of the annular bottom 114. A feeding port 113 is opened at the top of the annular cover 108. Two mounting ports 103 are opened at the bottom of the annular cover 108 in the clockwise direction of the feeding port 113. A discharging port 102 is opened at the bottom of the annular cover 108 in the counterclockwise direction of the feeding port 113. The flame spraying end of the flamethrower 109 penetrates through the inner circular shell 115. After the closed channel formed by the outer circular shell 101, the inner circular shell 115 and the annular cover 108 is divided into four treatment spaces by the partition plate 106, the four treatment spaces are sequentially divided into a feeding bin, a drying bin, a combustion bin and a discharging bin in the clockwise direction. When the partition plate 106 rotates with the rotating ring 104, it will push the medical waste to pass through the feeding bin, the drying bin, the combustion bin and the discharging bin in sequence. The design of the shovel plate 107 on the surface of the partition plate 106 can effectively prevent the material from adhering to the top of the annular bottom 114. After the flamethrower 109 is started, it can spray flames to ignite the medical waste inside the combustion bin. It should be noted that this device mainly incinerates biomass wastes such as medical bandages, cotton balls and cotton swabs, and the main body shell needs to select high-temperature resistant materials according to the actual situation.

[0034] A tooth 105 is provided near the middle of the outer surface of the rotating ring 104, and a connecting shell 110 is fixedly connected to the outer surface of the outer cylindrical shell 101 near the feeding port 113. A reduction gear set 111 is installed inside the connecting shell 110, and a servo motor 112 is installed on the top of the connecting shell 110. The reduction gear set 111 is used to drive the servo motor 112 and the tooth 105. The reduction gear set 111 consists of a compound gear and a pinion, and is used to transmit the driving force of the servo motor 112 to the tooth 105, thereby driving the rotating ring 104 to rotate. The reduction gear set 111 has the effect of reducing speed and increasing torque. The feeding port 113 is used to feed materials into the device.

[0035] The mounting shell 203 is fixedly connected between the inner surface walls of one of the mounting ports 103, and a plurality of blocking blocks 205 are fixedly connected to the inner bottom of the mounting shell 203. A support plate 204 is arranged above the mounting shell 203, and one side of the support plate 204 is bent downward. The outer surface of the support plate 204 is provided with a plurality of arc grooves 206 corresponding to the size of the blocking blocks 205. The blocking blocks 205 and the top of the mounting shell 203 and the top of the annular bottom 114 are in a horizontal state. The mounting shell 203 installed between the inner walls of the mounting port 103 is mainly used to accommodate the support plate 204, and one side of the support plate 204 is bent. The shovel plate 107 rotating in the clockwise direction will press the curved surface of the support plate 204 to make it gradually drop. When the shovel plate 107 passes, the top of the support plate 204 will lose pressure, and the blocking blocks 205 are used to block the arc grooves 206 on the surface of the support plate 204.

[0036] The bottom of the support plate 204 is fixedly connected with a plurality of through rods 207, the bottom of the mounting shell 203 is installed with a diverter shell 201, the top of the diverter shell 201 is embedded with a plurality of circular sleeves 208, the bottom end of the through rod 207 slides through the mounting shell 203 and extends into the inside of the circular sleeve 208, a spring 209 is fixedly connected between the inner bottom of the circular sleeve 208 and the bottom end of the through rod 207, the bottom of the diverter shell 201 is fixedly connected with an air intake pipe 202, the through rod 207 cooperates with the circular sleeve 208 inside the diverter shell 201 to limit the support plate 204 so that it can only move up and down within a certain stroke, and the rebound force provided by the spring 209 can be When the pressure above the plate 204 is lost, it is pushed upward, and the spring 209 and the combustion chamber are blocked by the mounting shell 203, which can reduce the high temperature resistance requirements for the spring 209 and increase the service life of the spring 209. A matrix air outlet is provided on the top of the diverter shell 201, and all the air outlets on the top are connected to the air inlet pipe 202 below, ensuring that the air can be evenly transported to the interior of the combustion chamber and that the transported air flows upward. A small amount of combustion dust that falls into the interior of the mounting shell 203 through the arc groove 206 can float upward without affecting the normal operation of the device. Holes are provided at the bottom of the mounting shell 203, and the holes correspond to the air holes on the top of the diverter shell 201.

[0037] The first blower 301 is fixedly installed at the bottom of the shunt housing 201 through a bracket, and the air outlet of the first blower 301 is fixedly communicated with the intake pipe 202. The air inlet of the first blower 301 is fixedly communicated with a first connecting pipe 302 extending upward. The upper end of the first connecting pipe 302 is fixedly communicated with a hollow housing 303. The hollow housing 303 is fixedly installed on the top of the annular cover 108 and is symmetrically positioned with the feeding port 113. The hollow housing 303 is installed on the top of the annular cover 108 and corresponds to the combustion chamber. This position is affected by combustion and the temperature is much higher than that of normal temperature air. After the first blower 301 is started, external air will first enter the inside of the hollow housing 303 to be heated, and then enter the inside of the combustion chamber through the first connecting pipe 302, the first blower 301, the shunt housing 201 and the installation housing 203 to provide oxygen, promoting the effective incineration of biomass medical waste.

[0038] The inside of the hollow housing 303 is hollow and there is an opening on the side away from the first connecting pipe 302. The top of the hollow housing 303 is fixedly communicated with a second connecting pipe 304. The second connecting pipe 304 is in a communicating state with the annular cover 108. The outer surface of the second connecting pipe 304 passes through from above the inner circular housing 115 and extends downward. The heating plate 305 is fixedly connected between the inner surfaces of another installation port 103. The lower end of the second connecting pipe 304 penetrates through the bottom of the heating plate 305 and extends upward. The heating plate 305 is located in the clockwise direction of the feeding port 113. There is a channel inside the hollow housing 303, and a circular opening is also provided at the corresponding position on the top of the annular cover 108 for communicating the bottom end of the second connecting pipe 304 with the inside of the combustion chamber. When the air helps combustion inside the combustion chamber, high-temperature gas will enter the drying chamber inside the device along with the flue gas from the inside of the second connecting pipe 304, so that the moisture in the medical waste inside the drying chamber is evaporated, and it has the effect of high-temperature sterilization, improving the subsequent combustion efficiency. The heating plate 305 is a heating element of the commercially available high-resistance electric heating wire type, which can convert electrical energy into heat energy and cooperate with high-temperature air to cause high-temperature cracking of the medical waste inside the drying chamber, and then generate smoke and gas that meet the conditions for secondary combustion. It should be noted that when there are substances with relatively low ignition points in the medical waste that burn under high-temperature conditions, since the high-temperature air sent in has participated in the combustion operation and contains a relatively low amount of oxygen, the accidentally burned medical waste will be in an insufficient combustion state, and a large amount of combustible smoke and gas will be generated. Moreover, the drying chamber is in a semi-closed state and there is no safety hazard.

[0039] Steps of using the present invention: After the closed channel formed by the outer circular shell 101, the inner circular shell 115, and the annular cover 108 in this device is separated into four treatment spaces by the partition plate 106, the four treatment spaces are sequentially divided into a feeding bin, a drying bin, a combustion bin, and a discharging bin in the clockwise direction. When in use, used biomass medical wastes such as gauzes, bandages, cotton balls, and cotton swabs are directly put into the feeding port 113. At this time, the wastes will fall into the feeding bin below. Then, start the servo motor 112 to drive the rotating ring 104 to rotate 90° in cooperation with the reduction gear set 111 and the teeth 105 on the surface of the rotating ring 104. At this time, the partition plate 106 inside the rotating ring 104 will push the medical wastes in the feeding bin into the drying bin. At this time, the inside of the feeding bin is in an idle state, and the next batch of medical wastes is put into it again. Start the servo motor 112 to drive the rotating ring 104 to rotate again and repeat the feeding. At this time, the biomass medical wastes inside the drying bin will enter the combustion bin. At this time, start the flame sprayer 109 to ignite the medical wastes, and start the first blower 301. The air will enter the inside of the combustion bin through the hollow shell 303, the first connecting pipe 302, the first blower 301, the shunt shell 201, and the mounting shell 203 to provide oxygen for combustion support. After the air supports combustion and forms high-temperature air, it will enter from below the drying bin through the second connecting pipe 304 above the combustion bin. At this time, the high-temperature air can perform high-temperature sterilization on the medical wastes inside the drying bin and promote the evaporation of the internal moisture. At the same time, it has a preheating effect and improves the subsequent combustion efficiency. When the medical wastes inside the combustion bin are fully incinerated, drive the partition plate 106 to rotate again through the servo motor 112. At this time, the shovel plate 107 at the bottom of the partition plate 106 will push the ash residues generated after the combustion of the medical wastes clockwise. When the ash residues pass through the feeding port 102, they can be discharged, thus completing the incineration treatment operation of medical wastes. And when the dried medical wastes enter the inside of the combustion bin, the previous partition plate 106 and the shovel plate 107 will squeeze the curved surface of the support plate 204, so that the support plate 204 moves downward, and drives the through rod 207 to squeeze the spring 209 inside the circular sleeve 208 to gradually contract. When the bottom of the partition plate 106 passes through the curved surface of the support plate 204 and reaches the horizontal plane, the support plate 204 is in the lowest state. At this time, the block 205 inside the mounting shell 203 will coincide with the arc groove 206 on the surface of the support plate 204, so that the surface of the support plate 204 is in a flat state, and the ash can be effectively pushed into the feeding port 102 to complete slag discharge. When the partition plate 106 completely passes through the support plate 204, another partition plate 106 will push the medical wastes in the drying bin into the upper part of the support plate 204 inside the combustion bin. At this time, the partition plates 106 and the shovel plates 107 on both sides of the support plate 204 are not in contact with the support plate 204, and the support plate 204 loses pressure. Therefore, the spring 209 will rebound and push the support plate 204 to move up and reset, so that a space is generated below the support plate 204 and the medical wastes are lifted upward. At the same time, under the action of the shunt shell 201, the air will flow evenly upward from below for combustion support.During the process, as the medical waste gradually burns and forms ashes, the ashes will be blown up and separated from the accumulated combustibles, ensuring that the medical waste is fully burned into ashes. As the number of batches of medical waste treatment increases, the temperature of the area where the annular cover 108 is located above the combustion chamber will rise, which plays a role in heating the hollow shell 303. Therefore, the temperature of the air entering the combustion chamber through the hollow shell 303 from the outside will rise. When assisting combustion, the combustion assisting effect can be effectively improved, thereby reducing the energy required for combustion. The integrated design of this device keeps the interior in a relatively closed state. When burning biomass medical waste inside the device, the heat generated can preheat the combustion assisting air, improve the combustion assisting effect, and at the same time, can perform high-temperature treatment on the next batch of medical waste, reducing the heat required for combustion, and having a good energy-saving effect.

[0040] Embodiment 2: As Figures 1-3 and Figure 8 shown, the difference based on the combination of the embodiments is that the housing 401 is fixedly installed on the top of the annular cover 108. The inner side of the housing 401 is fixedly connected with an inner liner 403. Both the upper and lower ends of the inner liner 403 are provided with openings. The bottom of the inner liner 403 is in a communicating state with the top of the annular cover 108. A plurality of through holes 405 are arranged in a row on the outer surface of the inner liner 403 near the inner top of the housing 401. A spiral piece 404 is fixedly connected between the outer surface of the inner liner 403 and the inner wall of the housing 401 near the lower part. The through holes 405 are used to communicate the internal space of the housing 401 and the internal space of the inner liner 403. The design of the spiral piece 404 makes a spiral channel formed between the housing 401 and the inner liner 403. After the high-temperature air in the drying chamber processes the medical waste, it will enter from below the inner liner 403 and be discharged from above.

[0041] A second blower 402 is installed at a position near the bottom of the outer surface of the housing 401. The upper end of the inner liner 403 extends above the housing 401. A filter cover 406 is sleeved on the top end of the inner liner 403. An igniter 407 is installed on the top of the housing 401. The ignition end of the igniter 407 penetrates the outer surface of the inner liner 403 and extends to the other side. The second blower 402 is used to send outside air into the interior of the housing 401. When the medical waste in the drying chamber undergoes high-temperature pyrolysis, combustible smoke and gas will be generated. At the same time, after the high-temperature air passes through the interior of the drying chamber, a certain amount of heat will remain. And under the action of the heating plate 305, the air entering the interior of the inner liner 403 from the drying chamber has a relatively high temperature. At this time, the air in the spiral channel inside the housing 401 will form high-temperature air through heat exchange and enter the interior of the inner liner 403 through the through holes 405. The igniter 407 is a prior art, and a suitable model and type can be selected according to needs.

[0042] The usage steps of the present invention are as follows. When the medical waste inside the drying chamber undergoes high-temperature pyrolysis, combustible smoke and gas are generated. At the same time, after the high-temperature air passes through the inside of the drying chamber, a certain amount of heat remains. And under the action of the heating plate 305, the air entering the inner liner 403 inside the drying chamber has a relatively high temperature. Meanwhile, the second blower 402 is started to send the outside air containing oxygen into the housing 401. The air will flow spirally upward through the spiral channel formed by the spiral fins 404. During this process, it will absorb the temperature on the surface of the inner liner 403 through heat exchange to form hot air. When the formed hot air enters the relatively narrow upper position inside the inner liner 403 through the through hole 405, it will be mixed with the smoke and gas generated by the high-temperature pyrolysis of the medical waste. During this process, the igniter 407 is started to ignite. Since the smoke and gas generated by the high-temperature pyrolysis are combustible after being mixed with the high-temperature air, they will instantly burn when encountering a flame until the medical waste inside the drying chamber enters the combustion chamber. Since the flue gas undergoes secondary combustion, substances such as unburned carbon black particles and carbon monoxide in the flue gas can be completely burned. The products generated after the secondary combustion are mainly carbon dioxide and water, thus presenting a smokeless state, avoiding the pollution of the environment by the flue gas generated after incinerating medical waste, and improving the incineration treatment effect of medical waste.

[0043] Embodiment 3: As Figure 1 、 Figure 2 and Figure 9 shown, the difference based on the combination of the embodiments lies in that the material receiving cover 501 is fixedly connected to the bottom of the annular bottom 114, and the top of the material receiving cover 501 is in communication with the material discharging port 102. A feeding pipe 502 is fixedly communicated with the outer surface of the material receiving cover 501 near the bottom. One end of the feeding pipe 502 is fixedly connected with a driving motor 503. A screw blade 504 is rotatably connected inside the feeding pipe 502. The output end of the driving motor 503 rotatably penetrates the outer surface of the feeding pipe 502 and is fixedly connected with the screw blade 504. The material receiving cover 501 is used to receive the ash residue falling from the material discharging port 102, and the driving motor 503 is used to drive the screw blade 504 to rotate, thereby conveying the dust residue outward from the inside of the feeding pipe 502.

[0044] The usage steps of the present invention are as follows. When the ash generated inside the combustion chamber is pushed by the shovel plate 107 and the partition plate 106 and passes through the material discharging port 102, it will fall into the lower material receiving cover 501 below, and will gather at the lower position inside the material receiving cover 501 under the action of gravity. At this time, a collection container is fixedly sealed at the outer end of the feeding pipe 502, and the driving motor 503 is started to drive the screw blade 504 to rotate. At this time, under the action of the screw blade 504, the ash can be stably conveyed into the collection container, and the entire slag discharge path is in a relatively closed state, and the slag discharge and conveying process is stable, thereby effectively avoiding the problem of ash scattering and polluting the environment, and having a good environmental protection effect.

[0045] Among them, the flamethrower 109, the servo motor 112, the first blower 301, the heating plate 305, the second blower 402, the igniter 407, and the drive motor 503 are all prior arts, and their components and principles of use are all publicly known technologies, and no further explanations will be given here.

[0046] Although the present invention 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 perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
