[0003] In the existing microwave treatment devices for new medical solid waste, the steam inlet is directly arranged in the treatment barrel of the microwave device. During the material treatment, the barrel is directly heated by the microwave generator, and at the same time, high-temperature steam is input. Along with the treatment action of the crushing mechanism, the crushed materials in the barrel are very easy to be thrown into the steam inlet by the crushing mechanism along with the air flow, thus causing serious pollution and residue to the steam inlet.

[0040] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.
[0041] Please refer to Figure 1 and Figure 2 , a microwave treatment device for new-type medical solid waste, comprising a partition mechanism 10 and a crushing mechanism 20; the partition mechanism 10 includes an outer barrel 11, an isolation inner sleeve 12 fixedly arranged inside the outer barrel 11, and at least one microwave generator 13 installed on the outer side wall of the outer barrel 11. After the barrel cover 114 is covered, the outer barrel 11 can form a closed space, which includes a treatment space inside the isolation inner sleeve 12 and an isolation space between the isolation inner sleeve 12 and the outer barrel 11. And the treatment space and the isolation space are independent of each other. The treatment space is used for placing the object to be microwave-treated. The outer barrel 11 is provided with openings corresponding to the microwave generators 13 one by one for the microwave to pass through, so that the microwave radiates towards the isolation inner sleeve 12; the material of the isolation inner sleeve 12 is polyamide-imide or polyimide or Teflon; a first ventilation port 111 is further opened on the outer side wall of the outer barrel 11 for inputting steam into the isolation space; the crushing mechanism 20 includes a turntable driving motor and a crushing knife set arranged at the bottom of the outer barrel 11.
[0042] As a whole, by setting the isolation inner sleeve 12, the closed space inside the outer barrel 11 is divided into an isolation space and a processing space. On the one hand, the first ventilation opening 111 is arranged in the isolation space to isolate the direct contact between the object to be microwave-processed and the first ventilation opening 111. On the other hand, the isolation inner sleeve 12 made of polyamide-imide or polyimide or Teflon is arranged in the area and position irradiated by the microwave. The good high heat resistance and mechanical strength of the polyamide-imide or polyimide or Teflon material can be utilized, and combined with its property of being microwave-permeable, it can effectively and skillfully realize the heating of the object to be processed in the barrel by the microwave passing through the isolation inner sleeve 12 while ensuring the service life in the high-speed rotating crushing environment. In addition, in the use environment of high-speed rotation and large-area contact with the material, the toughness of its material is also crucial. It is necessary to avoid choosing some materials with high brittleness such as glass as much as possible to reduce the risk of the isolation inner sleeve being easily broken during the high-speed crushing work.
[0043] Please refer to Figure 2 , the outer barrel 11 includes an upper barrel body 116 and a lower barrel body 117. The diameter of the upper barrel body 116 is larger than that of the lower barrel body 117 to form a bearing boss 1161 at the separation. The partition mechanism 10 further includes a fixing frame 14 arranged on the bearing boss 1161. The material of the fixing frame 14 can be stainless steel. The fixing frame 14 includes two concentric fixing rings 141 arranged up and down and a plurality of connecting fixing plates 142 connected between the two fixing rings 141. A supporting bottom ring 143 is further extended inward at the bottom of the lower fixing ring 141. The isolation inner sleeve 12 is fixed inside the fixing frame 14 and arranged above the supporting bottom ring 143 to provide all-round support and protection for the isolation inner sleeve 12. The isolation inner sleeve 12 is further detachably fixed inside the fixing frame 14 by a plurality of bolts. A silica gel ring is further arranged above the isolation inner sleeve 12. The height of the silica gel ring is higher than the highest point of the outer barrel 11 to form a sealing ring after the barrel cover 114 is covered to prevent the pulverized solid waste dust from entering the isolation space or the outside of the barrel. At the same time, there is a gap when the silica gel ring is fixed, allowing steam to enter or be extracted from the processing space. At the same time, water can also be sprayed inside the barrel to quickly form steam in cooperation with high temperature. An opening is formed by enclosing between every two adjacent connecting fixing plates 142 and the fixing ring 141 to allow the microwave to pass through along the radiation direction of the microwave generator 13.
[0044] The overall structure of the fixing frame 14 cooperating with the isolation inner sleeve 12 can, on the one hand, effectively support and protect the isolation inner sleeve 12, avoiding the easy damage of the isolation inner sleeve 12 during high-speed rotation. On the other hand, the structure of the silicone ring cooperating with the isolation inner sleeve 12 can form a completely enclosed processing space, preventing the pulverized dust from running out and affecting the first air vent 111 or causing secondary pollution outside the barrel.
[0045] Please refer to Figure 2 , the isolation space is located between the upper barrel body 116 and the isolation inner sleeve 12, and a conductive cloth 15 is further provided around the top of the upper barrel body 116 to isolate the enclosed space from the external space. Since the microwave is first radiated into the processing space through the isolation space by the microwave generator 13, the isolation space will also be filled with microwave. Therefore, the conductive cloth 15 is provided at the top of the upper barrel body 116 to shield the microwave and prevent the microwave from leaking from the enclosed space to the external space. The structural design is simple and ingenious, and the function is easy to implement.
[0046] Furthermore, the pulverizing knife group includes an isolation turntable 21 arranged above the inner bottom surface of the lower barrel body 117, rotating blades 22 arranged on the isolation turntable 21, and shear blades 23 arranged on the inner side surface of the lower barrel body 117. The drive shaft of the turntable drive motor passes through the bottom of the outer barrel 11 from the outside and is connected to the isolation turntable 21. Since there are textiles such as long zippers, gauzes, and sheets in medical solid waste, it is easy to occur in traditional solid waste pulverizing equipment that the material cannot be cut off, causing the material to rotate with the barrel body or entangle the knife. Therefore, the overall structure of the rotating blades 22 cooperating with the shear blades 23 enables the rotating blades 22 to approach the shear blades 23 when rotating past the shear blades 23 to form a shearing force to cut and pulverize the solid waste entangled on the rotating blades 22. The rotating blades 22 include a number of vertically upward cutting edges, and the outer cutting edges are located at the outer edge of the turntable body 211. The shear blades 23 include a number of horizontally arranged cutting edges, and the bottommost cutting edge is arranged close to the cutting edge of the rotating blades 22.
[0047] Please refer to Figure 2 and Figure 3, the isolation turntable 21 includes a turntable body 211 and at least one wave-transmitting member 212 fixedly provided on the turntable body 211. A wave-transmitting port is provided on the turntable body 211 opposite to the wave-transmitting member 212. The material of the wave-transmitting member 212 is polyamideimide or polyimide or Teflon or borosilicate; the wave-transmitting member 212 can be semi-circular or quarter-circular or circular; a plurality of isolation blades 24 are further provided at the bottom of the turntable body 211, and the isolation blades 24 extend from the axis of the driving shaft of the turntable driving motor towards the outer edge of the turntable body 211. Preferably, the number of the isolation blades 24 is four and they are in a triangular prism shape. The four isolation blades 24 are symmetrically arranged at the center and all extend obliquely from the axis of the driving shaft to the outer edge of the turntable body 211, and their extending directions are not the same as the radius direction to increase the length of the isolation blades 24 as much as possible. In this embodiment, the turntable driving motor is driven by a belt.
[0048] The crushing mechanism 20 as a whole adopts the structure of the wave-transmitting member 212 cooperating with the isolation blades 24. On the one hand, it can effectively ensure that the microwave can pass through the wave-transmitting member 212 to heat and disinfect the area below the turntable body 211 by selecting the material of the wave-transmitting member 212, and can also enhance the microwave through the reflection of the bottom metal. At the same time, the turntable body 211 can support and fix the wave-transmitting member 212; on the other hand, since there is a gap between the turntable body 211 and the bottom of the outer barrel 11 to avoid direct friction between the two, the driving shaft of the turntable driving motor will be exposed below the turntable body 211. The crushed solid waste is very easy to approach the driving shaft during high-speed rotation, causing problems such as the driving shaft being entangled with the knife or damaged. Therefore, through the high-speed centrifugal force generated by the high-speed rotation of the isolation blades 24, the crushed materials below the turntable body 211 can be thrown out along the blade slope, and the isolation effect generated by the high-speed rotation of the outer edge of the isolation blades 24 can be used to further prevent the crushed materials in the barrel from entering below the turntable body 211.
[0049] Preferably, the number of the wave-transmitting members 212 is four, and the wave-transmitting members 212 are quarter-circular. The four wave-transmitting members 212 are symmetrically distributed at the center. The wave-transmitting ports opened on the turntable body 211 are also four quarter-circular openings. Each wave-transmitting port further extends horizontally inward at the bottom with a support portion. The wave-transmitting member 212 can be placed in a limited way on the support portion and is detachably fixed to the support portion by a plurality of quarter-circular pressing pieces and bolts. On the one hand, it ensures the stable and fixed installation of the wave-transmitting member 212 and improves the service life; on the other hand, after one or more wave-transmitting members 212 are worn or damaged, they can be replaced separately, effectively reducing the overall use cost.
[0050] Please refer to Figure 2, the number of the microwave generators 13 is at least four, and the microwave generators 13 are distributed on the outer side wall of the outer barrel 11 and are within the height range of the upper barrel body 116, that is, within the height range of the isolation inner sleeve 12; through a plurality of uniformly arranged microwave generators 13 cooperating with the isolation inner sleeve 12 at the corresponding positions, it can effectively ensure uniform heating of the processing space in the barrel.
[0051] The microwave generator 13 is a prior art and is composed of a plurality of microwave heating components, including a microwave switching power supply, a magnetron, a rectangular waveguide, etc., and can be directly purchased on platforms such as 1688 by searching keywords such as relevant industrial microwave drying equipment components or industrial microwave heating equipment components, etc., and will not be elaborated here.
[0052] Please refer to Figure 4 and Figure 5 , the microwave device further includes at least one communication sensing structure 60, the communication sensing structure 60 includes a liquid heat conduction part 61 and a temperature sensor 62 connected to each other, a heat conduction liquid in contact with the sensing part of the temperature sensor 62 is contained in the liquid heat conduction part 61, the liquid heat conduction part 61 is arranged in the isolation space to realize heating of the heat conduction liquid by microwave passing through the isolation inner sleeve 12, and the temperature sensor 62 is arranged outside the outer barrel 11.
[0053] In a conventional industrial microwave device, since it is necessary to detect the microwave intensity or temperature in the device in real time to control parameters such as the heating time and heating temperature of microwave and steam and improve the microwave processing effect; and in the current prior art, such detection can often only be carried out through a microwave detector or a temperature sensor 62, etc. On the one hand, the temperature sensor 62 will be affected by microwave interference and / or high temperature, resulting in the inability to transmit the electrical signal and the inability to effectively obtain the temperature; on the other hand, the microwave detector is also easily damaged in a high temperature environment, and using a high-end microwave detector will also greatly increase the detection cost.
[0054] Therefore, by setting the isolation inner sleeve 12 made of polyamideimide or polyimide or Teflon or high borosilicate material to divide the space in the outer barrel 11 into a processing space and a partition space, on the one hand, the liquid heat conduction part 61 of the communication sensing structure 60 is arranged in the partition space to utilize the properties of high borosilicate such as microwave permeability, high heat resistance and high mechanical strength to heat the heat conduction liquid in the liquid heat conduction part 61 by microwave; on the other hand, the temperature sensor 62 is arranged outside the outer barrel 11, and the metal material property of the outer barrel 11 is used for heat insulation and microwave isolation to ensure that the temperature sensor 62 is not interfered, so as to realize the temperature acquisition of the heat conduction liquid through the temperature sensor 62, and cleverly realize the detection of the temperature in the barrel, so as to accurately adjust and control the relevant parameters of microwave processing based on the temperature and ensure the microwave processing effect.
[0055] The connected sensing structure 60 is U-shaped. The liquid heat conducting part 61 includes a connecting piece 611 and a heat conducting liquid storage piece 612. The connecting piece 611 is arranged across the outer barrel 11. Through the U-shaped setting, the temperature sensor 62 and the heat conducting liquid storage piece 612 can be effectively arranged on both sides of the side wall of the outer barrel 11 respectively. At the same time, by using the principle of the U-shaped communicating vessel, the temperature is transmitted from the inside of the barrel to the outside of the barrel through the setting of the connecting piece 611, and the temperature acquisition is cleverly realized.
[0056] Further, the connecting piece 611 includes a horizontal fixing pipe and connecting bent pipes respectively connected to both ends of the horizontal fixing pipe. One connecting bent pipe is connected to the heat conducting liquid storage piece 612 through a first adapter; the other connecting bent pipe is connected to the temperature sensor 62 through a second adapter. By fixing the horizontal fixing pipe on the side wall of the outer barrel 11 in advance, it is convenient for the subsequent installation of the two connecting bent pipes and the adapters.
[0057] Furthermore, the heat conducting liquid storage piece 612 is tubular, used to pour the heat conducting liquid from the outside, and at the same time guide the heat conducting liquid along the adapter, the connecting bent pipe, the horizontal fixing pipe, etc. to contact the sensing part of the temperature sensor 62. The first adapter is hollow and convex-shaped, and internal threads are provided at both ends for detachable connection with the connecting bent pipe and the heat conducting liquid storage piece 612 respectively; the second adapter is convex-shaped in the middle and internal threads are provided at both ends for detachable connection with the other connecting bent pipe and the temperature sensor 62 respectively; through the detachable structure of multiple components, it can effectively realize that in the subsequent high-temperature and microwave use environments, once any component is damaged, it can be quickly replaced. The overall structure design is simple and easy to replace, which can effectively reduce the subsequent use cost.
[0058] In addition, the heat conducting liquid is oil (such as diesel, kerosene, rapeseed oil, gasoline, etc.). Since the temperature inside the microwave device is often higher than 100 degrees Celsius, if water is used, the heat conducting liquid will be insufficient due to evaporation, while the high boiling point of oil can effectively adapt to this application scenario. At the same time, other conventional high-boiling heat conducting liquids can also be used; or when the accuracy requirement is not high, a thermocouple temperature sensor with an all-steel structure can also be directly set in the processing space for identification.
[0059] The number of the connected sensing structures 60 is at least four. Preferably, the number of the connected sensing structures 60 is eight; the microwave generators 13 are distributed on the outer side wall of the outer barrel 11 and are all within the height range of the isolation inner sleeve 12; the connected sensing structures 60 are distributed on the side wall of the outer barrel 11, generally divided into two groups, upper and lower, with four in each group and evenly distributed, and the two groups are staggered to realize the temperature detection of each part inside the barrel and ensure the microwave heating effect.
[0060] Please refer toFigure 2 and Figure 6 The microwave device further includes a self-cleaning mechanism 30, which includes a cleaning drive motor 31 and a cleaning member 32. The cleaning drive motor 31 is fixed above the barrel cover 114, and its drive shaft passes through the barrel cover 114 and is connected to the cleaning member 32 arranged below the barrel cover 114. The cleaning member 32 is horizontally arranged and contacts the bottom of the barrel cover 114.
[0061] Specifically, the cleaning member 32 includes a scraper fixing plate 321 and a first cleaning scraper 322 fixed to one side of the scraper fixing plate 321. The outermost end of the cleaning scraper is as close to the inner wall of the outer barrel 11 as possible, and the upper edge of the cleaning scraper is as close to the bottom surface of the barrel cover 114 as possible for scraping the inner wall of the barrel cover 114 after being driven by the cleaning drive motor 31. At the same time, the length of the scraper fixing plate can also be extended to the inner wall of the outer barrel 11 as much as possible, and a second cleaning scraper 323 is fixed at the end of the scraper fixing plate. The second cleaning scraper The length of the knife 323 only needs to be 0.1 to 0.2 of the height of the outer barrel 11. The second cleaning scraper 323 is designed to match the shape of the inner wall of the outer barrel 11 so that the scraper part is as close to the inner wall of the outer barrel 11 as possible. When the first cleaning scraper 322 rotates to clean, it drives the second cleaning scraper 323 on the scraper fixing plate to move together, and scrapes off the crushed solid waste attachments on the side wall of the outer barrel 11 at a high place. The structural design of the overall cleaning part 32 is simple and ingenious, which can effectively realize the cleaning effect of the inner wall of the barrel.
[0062] Please refer to Figure 7 and Figure 8 The microwave equipment further includes a circulating cooling system 40; a second ventilation port 112 and a third ventilation port 113 are further opened on the outer wall of the outer barrel 11; the circulating cooling system 40 includes a first pipeline 41 connected to the second ventilation port 112, a first blowing mechanism 42 connected to the first pipeline 41, a second pipeline 43 connected to the air outlet of the first blowing mechanism 42, a transfer bin 44 connected to the second pipeline 43, and a third pipeline 45 connected to the transfer bin 44; the third pipeline 45 is connected to the third ventilation port 113.
[0063] The whole first extracts the steam from the barrel through the circulation pipeline formed by the second ventilation port 112, the first pipeline 41, the first blowing mechanism 42, the second pipeline 43, the transfer bin 44, the third pipeline 45 and the third ventilation port 113, and reduces the temperature in the barrel through natural gas movement and transportation; the barrel is cooled through the circulating gas pipeline system, and the structural design is ingenious and the function is easy to use.
[0064] The microwave device further includes a refrigeration system, which includes a compressor, a condenser, and an evaporator connected by connecting pipes; the first air blowing mechanism 42 includes a first air blowing motor and an air blowing chamber; the evaporator is disposed in the air blowing chamber, and the air outlet of the air blowing chamber is communicated with a second pipeline 43. By the principle of an existing air-conditioning refrigeration system, the evaporator is disposed in the air blowing chamber to rapidly cool the steam passing through the air blowing chamber.
[0065] In addition, the circulating cooling system 40 further includes a fourth pipeline 46 communicated with a third ventilation opening 113 and a fifth pipeline 47 communicated with a second ventilation opening 112. The fourth pipeline 46 is further communicated with a second air blowing mechanism 48. An activated carbon chamber 49 is disposed on one side of the second air blowing mechanism 48, and the gas is deodorized by the activated carbon before being discharged. Through the structures of the fourth pipeline 46 and the second air blowing mechanism 48, after the steam is extracted, the gas in the barrel is purified and deodorized again.
[0066] A first valve 50 is disposed on the first pipeline 41, a second valve 51 is disposed on the third pipeline 45, a third valve 53 is disposed on the fourth pipeline 46, the fifth pipeline 47 is communicated with the external space of the microwave device, and a fourth valve 54 is disposed on the fifth pipeline 47. By opening the third valve 53 and the fourth valve 54 and closing the first valve 50 and the second valve 51, the gas in the barrel can be effectively purified and deodorized after the steam is extracted and the cooling work is completed, that is, the second air blowing mechanism 48 sucks air, the gas is drawn in from the outside through the fourth pipeline 46, passes through the barrel, and then passes through the fifth pipeline 47 and is finally discharged. Conversely, by closing the third valve 53 and the fourth valve 54 and opening the first valve 50 and the second valve 51, the cooling of the barrel can be quickly achieved.
[0067] The third pipeline 45 and the fourth pipeline 46 are communicated with the third ventilation opening 113 through a tee; the fifth pipeline 47 and the first pipeline 41 are communicated with the second ventilation opening 112 through a tee. Through such a tee connection structure, the pipeline cost at the connection and the production cost of the opening on the outer barrel 11 can be effectively reduced, and it is avoided that more elbows and ventilation openings are required to realize the connection of the gas path.
[0068] Please refer to Figure 1 、 Figure 7 and Figure 9, further including a material receiving mechanism 70, a device support 80 and a housing 90. An outlet 115 is provided on the lower barrel body 117, and the outlet 115 is opened and closed by a switch door. The fixed frame 14 and the isolation inner sleeve 12 are in a frustum shape with a wider top and a narrower bottom. The material receiving mechanism 70 includes a guiding cover 71 disposed on one side of the outlet 115 and fixed to the device support 80, and a material receiving box 72 disposed below the guiding cover 71. The guiding cover 71 is provided with a relief opening for the outlet 115 to discharge materials and for the switch door to enter, and the bottom opening is used to introduce the treated medical solid waste into the material receiving box 72. The material receiving box 72 can be a push-pull recycling cart.
[0069] The overall fixed frame 14 and the isolation inner sleeve 12 are in a frustum shape with a wider top and a narrower bottom. On the one hand, it can effectively increase the storage space inside the overall barrel to a large extent by increasing a small amount of height without changing the bottom radius, which can meet the processing space requirements of different customers. On the other hand, its tapered inner inclined surface can also play a role in supporting the gravity of the solid waste in the barrel, avoiding all the gravity being applied to the turntable main body 211, and effectively improving the service life of the turntable main body 211 and the turntable drive motor.
[0070] A microwave treatment method for medical solid waste, which applies the treatment device, includes the following steps:
[0071] S1: Open the barrel cover 114 and put in medical solid waste;
[0072] S2: Start the crushing knife group to crush the medical solid waste;
[0073] S3: Input steam into the isolation space through the first ventilation port 111 and make the humidity inside the entire outer barrel 11 reach the specified humidity, and the humidity needs to reach more than 90%;
[0074] S4: Start the microwave generator 13;
[0075] S5: After the medical solid waste meets the treatment requirements (the treatment requirements can directly refer to the national ecological environment standard of the People's Republic of China, standard number: HJ229—2021, document name: Technical Specification for Microwave Disinfection Centralized Treatment Engineering of Medical Waste, which will not be elaborated here), turn off the crushing knife group and the microwave generator 13, and stop inputting steam;
[0076] S6: Extract the steam through the circulating cooling system 40 and input cold air at the same time to cool the inside of the outer barrel 11;
[0077] S7: When it is cooled to the specified temperature (i.e., about 65°C), stop cooling, open the switch door of the outlet 115, and turn on the turntable drive motor. Use the centrifugal force generated by the rotation of the turntable to throw out the treated medical solid waste for collection;
[0078] S8: Close the switch door and wait for the next processing operation.
[0079] This processing method can effectively achieve the cooling of the inside of the barrel, and can also ensure that the first ventilation port 111 will not be contaminated by medical solid waste, ensuring the processing effect. At the same time, when opening the lid after cooling to about 65°C, on the one hand, the temperature is not too high, which will not cause danger or comfort impact on the human body due to the hot air when the operator opens the lid. On the other hand, it can also save energy. When using it next time, it can start heating from a relatively high temperature, which is convenient for quickly reaching the specified temperature.
[0080] Specifically, in step S6, by opening the third valve 53 and the fourth valve 54 and closing the first valve 50 and the second valve 51, it can effectively achieve the purification and deodorization of the gas inside the barrel after extracting steam and completing the cooling work, that is, by the second air blowing mechanism 48 to draw air, the gas is drawn in from the outside through the fourth pipeline 46, passes through the inside of the barrel and then through the fifth pipeline 47 and finally discharged. Conversely, by closing the third valve 53 and the fourth valve 54 and opening the first valve 50 and the second valve 51, the inside of the barrel can be quickly cooled to prepare for the next processing operation.
