Description

Technical Field

[0001] This invention relates to the field of protective clothing processing equipment, and in particular to a medical waste protective clothing processing equipment and processing method. Background Technology

[0002] Medical waste refers to waste generated by medical and health institutions during medical treatment, prevention, healthcare, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. Medical waste contains various pathogens, which can be inhaled through the respiratory tract via aerosols generated from the waste, posing a health risk. For example, when dealing with highly infectious viruses, it is extremely important for medical waste disposal equipment to achieve in-situ harmlessness and volume reduction.

[0003] Existing in-situ medical waste disposal equipment falls into the following categories: The first category primarily uses melt extrusion equipment, which mixes and extrudes medical waste at high temperatures (150-300 degrees Celsius), then granulates the mixture to obtain plastic masterbatch. The second category mainly utilizes disinfectant spraying and soaking to disinfect medical waste. This involves mixing crushed medical waste with a certain concentration of disinfectant (sodium hypochlorite, peracetic acid, glutaraldehyde, ozone, etc.) and ensuring sufficient contact area and time between the waste and the disinfectant. During disinfection, organic matter is decomposed and microorganisms are killed. However, maximizing contact between the disinfectant and the medical waste is a prerequisite for ensuring effective treatment. The third type of equipment mainly utilizes incineration, a high-temperature chemical process. Medical waste undergoes three stages—drying, ignition, and incineration—to convert it into residue and gases such as carbon dioxide. However, the final emissions of flue gas and residue require harmless treatment. The fourth type of equipment primarily utilizes high-temperature pyrolysis, addressing the instability of organic matter in medical waste by heating and distilling it under anaerobic or hypoxic conditions. This causes the organic matter to undergo thermal decomposition, converting the medical waste into energy substances such as oil and gas. The fifth type of equipment involves the use of ultraviolet disinfection lamps as a supplement to disinfectants for medical waste. Most of these technologies are equipped with pulverizing devices in the initial stages to crush the medical waste.

[0004] The first type of equipment produces plastic masterbatches with complex compositions and a narrow range of applications. It also cannot eliminate medical waste-related pollution problems such as bacteria and viruses, making it unsuitable for large-scale promotion and use. The second type of equipment requires the use of large amounts of disinfectants and does not achieve volume reduction of medical waste, so it is not a medical waste in-situ treatment device in the strict sense. The third and fourth types of equipment both involve high-temperature reactions, which not only consume a lot of energy but also easily produce exhaust gases such as dioxins that pollute the environment. In the fifth type of equipment, although ultraviolet lamps can disinfect medical waste, they cannot further reduce the volume of medical waste based on ultraviolet lamps.

[0005] This technology provides a medical waste protective clothing treatment device to solve the technical problems of high energy consumption, secondary pollution, inability to dispose of in-situ and inability to reduce the volume of waste in existing technologies. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problems of high energy consumption, secondary pollution, inability to dispose of in-situ and inability to reduce the volume of medical waste protective clothing in the existing protective clothing processing equipment, and to propose a medical waste protective clothing processing equipment and processing method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A medical waste protective clothing treatment device includes a crushing box, and further includes: a feeding box with a feeding port on the top, fixedly connected to the upper end of the crushing box, wherein the lower end of the feeding box is provided with a connecting pipe communicating with the crushing box, and two continuously rotating crushing rollers are installed inside the crushing box; a processing box, detachably installed at the lower end of the crushing box, wherein the upper end of the processing box and the lower end of the crushing box are provided with interconnected channels, and electric gates are fixedly installed in both the channels and the connecting pipe; a honeycomb-shaped distribution of first ultraviolet lamps is fixedly installed on the inner wall of the processing box; and a vacuum pump, fixedly installed on the outer wall of the crushing box, with the suction end of the vacuum pump extending into the crushing box.

[0009] To improve the disinfection and degradation speed of protective clothing fragments, preferably, a cylindrical rod extending into the side wall of the treatment box is inserted therein, and a stirring rod is fixedly connected to the outer wall of the cylindrical rod. A second ultraviolet lamp with a honeycomb distribution is fixedly installed on the outer wall of the cylindrical rod, and a drive motor is fixedly installed on the outer wall of the treatment box. The output shaft of the drive motor is connected to the cylindrical rod through a reciprocating mechanism.

[0010] To drive the stirring rod to reciprocate, the reciprocating mechanism further includes a hexagonal hole at the end of the cylindrical rod shaft, into which a hexagonal rod is inserted, and the hexagonal rod is fixedly connected to the output shaft of the drive motor; a turntable is rotatably connected to the end of the cylindrical rod shaft, and an elastic airbag is fixedly installed between the turntable and the inner wall of the processing box, and a tension spring is fixedly installed between the inner walls of the elastic airbag; wherein, two symmetrically arranged rollers are fixedly installed on the outer wall of the cylindrical rod, and the rollers abut against the outer wall of the processing box; and two symmetrically arranged protrusions are fixedly connected to the outer wall of the processing box.

[0011] To further prevent exhaust gas from polluting the air, the upper end of the treatment box is fixedly connected to an exhaust gas pipe, and a filter element is detachably installed at the end of the exhaust gas pipe.

[0012] To further prevent the protective suit from getting tangled in the stirring rod, an inner tube is fixedly connected inside the cylindrical rod, and an air blowing pipe extending to the outer wall of the cylindrical rod is fixedly connected to the inner tube. The end of the air blowing pipe faces the outer wall of the stirring rod, and a heat-conducting plate extending into the inner tube is fixedly connected to the second ultraviolet lamp.

[0013] To further enable automatic air blowing into the inner tube, the elastic airbag is fixedly connected to an air intake pipe and an air exhaust pipe that communicate with it. A one-way valve is fixedly installed inside both the air intake pipe and the air exhaust pipe. The end of the air exhaust pipe is fixedly connected to and communicates with the inner tube.

[0014] To dissipate heat from the first ultraviolet lamp, preferably, a heat dissipation cavity is provided inside the inner wall of the processing box, a circulation pipe is fixedly installed inside the heat dissipation cavity, and a heat dissipation circulation pump is fixedly installed on the outer wall of the processing box, with both ends of the heat dissipation circulation pump fixedly connected to both ends of the circulation pipe.

[0015] To further prevent dust from entering the processing chamber, a rectangular frame is fixedly connected to the outer wall of the processing chamber, and a filter plate is detachably installed inside the port of the rectangular frame, with the end of the suction pipe extending into the rectangular frame.

[0016] To facilitate the replacement and maintenance of the processing box, preferably, a T-shaped block is fixedly connected to the lower end of the crushing box, and a T-shaped groove is provided at the upper end of the processing box, into which the T-shaped block is inserted.

[0017] A method for disposing of waste medical protective clothing, the operation steps are as follows:

[0018] Step 1: Dispose of the used protective suit into the disposal box through the disposal port;

[0019] Step 2: Turn on the vacuum pump to create negative pressure inside the crushing chamber, and then open the electric gate on the connecting pipe;

[0020] Step 3: Suck the protective suit into the top of the crushing chamber, then close the electric gate in the connecting pipe and turn the vacuum pump on again to create a vacuum inside the crushing chamber.

[0021] Step 4: The protective suit inside the crushing chamber is crushed by two continuously rotating crushing rollers;

[0022] Step 5: Open the electric gate in the connecting pipe again, and then open the electric gate in the through slot;

[0023] Step 6: After the shredded protective suit falls into the processing box, close the two electric gates and turn on the first ultraviolet lamp, the second ultraviolet lamp, and the drive motor.

[0024] Compared with the prior art, the present invention provides a medical waste protective clothing treatment device, which has the following beneficial effects:

[0025] 1. This medical waste protective clothing processing equipment uses two continuously rotating crushing rollers to crush the protective clothing in the crushing box, causing the crushed protective clothing at the bottom of the crushing box to fall into the processing box. The first ultraviolet lamp on the inner wall of the processing box is turned on, and the protective clothing is irradiated, which can disinfect and decompose the crushed protective clothing, realizing the in-situ harmless and volume reduction of the protective clothing, reducing the transportation and processing costs of protective clothing. The protective clothing is processed under mild conditions such as room temperature, without the need for high temperature, reducing energy consumption and carbon consumption.

[0026] 2. This medical waste protective clothing processing equipment uses a drive motor to rotate a cylindrical rod, a second ultraviolet lamp to increase the disinfection and decomposition speed of the protective clothing, and a stirring rod to efficiently flip the pulverized protective clothing, making the disinfection and decomposition speed of the protective clothing higher and more complete.

[0027] 3. This medical waste protective clothing processing equipment uses a cylindrical rod to drive two rollers to sweep around in a circular motion. The cylindrical rod will drive the stirring rod and the second ultraviolet lamp to move back and forth. The stirring rod can improve the turning effect of the protective clothing, and the reciprocating movement of the second ultraviolet lamp can also increase the irradiation area, thereby further improving the disinfection and degradation efficiency of the protective clothing. At the same time, the reciprocating movement of the stirring rod can also reduce the probability of the protective clothing getting tangled.

[0028] 4. This medical waste protective clothing processing equipment uses a cylindrical rod to squeeze an elastic airbag, and the air blowing pipe blows off the protective clothing wrapped around the stirring rod. On the one hand, it prevents the protective clothing from getting tangled in the stirring rod, and on the other hand, it improves the turning effect of the protective clothing, making the disinfection and degradation effect of the protective clothing better. Furthermore, when the air passes through the inner tube, it will also carry away some of the heat from the heat-conducting plate, thereby dissipating heat from the second ultraviolet lamp. The heated air entering the processing chamber will further promote the degradation of the protective clothing.

[0029] 5. In this medical waste protective clothing treatment equipment, the elastic airbag draws in outside air through the suction pipe, which then blows outside air into the treatment chamber through the circumferentially sweeping air pipe. This allows the protective clothing to receive more oxygen during degradation, thus increasing the degradation rate. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Example 1:

[0042] Reference Figures 1-8 A medical waste protective clothing processing device includes a crushing box 1, and further includes: a feeding box 2 with a feeding port 3 on the top, fixedly connected to the upper end of the crushing box 1, wherein the lower end of the feeding box 2 is provided with a connecting pipe 4 communicating with the crushing box 1, and two continuously rotating crushing rollers 5 are installed inside the crushing box 1. The crushing rollers 5 are mainly driven by a power device, which can be an internal combustion engine or a servo motor; a processing box 6, detachably located at the lower end of the crushing box 1, wherein the upper end of the processing box 6 and the lower end of the crushing box 1 are provided with interconnected channels 7, and electric gates 8 are fixedly installed in both the channels 7 and the connecting pipe 4; a honeycomb-shaped distribution of first ultraviolet lamps 10 is fixedly installed on the inner wall of the processing box 6; a vacuum pump 9, fixedly installed on the outer wall of the crushing box 1, the suction end of the vacuum pump 9 extending into the crushing box 1, and a discharge port at the lower end of the processing box 6;

[0043] During use, the used protective suit is dropped into the disposal box 2 through the disposal port 3. When degradation treatment of the protective suit is required, the vacuum pump 9 is turned on, which creates negative pressure inside the crushing box 1. Then, the electric gate 8 on the connecting pipe 4 is opened, and the crushing box 1 draws air into the disposal box 2 through the connecting pipe 4. Some of the protective suit inside the disposal box 2 is sucked into the top of the crushing box 1. Then, the electric gate 8 in the connecting pipe 4 is closed, and the vacuum pump 9 is turned on again to create a vacuum state inside the crushing box 1. Then, the protective suit inside the crushing box 1 is crushed by two continuously rotating crushing rollers 5. Crushing the protective suit in a vacuum environment can effectively prevent the reaction and oxidation of the protective suit by gas, moisture, or oxygen. The crushed protective suit will fall to the bottom of the crushing box 1. At this time, the connecting pipe 9 is turned on again. The electric gate 8 inside the pipe 4 causes the next batch of protective clothing to be sucked into the crushing box 1 due to the negative pressure. Then, the electric gate 8 inside the channel 7 is opened, and the protective clothing crushed at the bottom of the crushing box 1 will fall into the processing box 6 through the channel 7. Then, the two electric gates 8 are closed, and the first ultraviolet lamp 10 on the inner wall of the processing box 6 is turned on. The first ultraviolet lamp 10 will irradiate the protective clothing, which can disinfect and decompose the crushed protective clothing, realize the in-situ harmless and volume reduction treatment of the protective clothing, reduce the transportation and processing costs of the protective clothing, and process the protective clothing under mild conditions such as room temperature, without the need for high temperature, reducing energy consumption and carbon consumption. It has the best treatment effect on protective clothing composed of photodegradable plastic, which can quickly degrade the protective clothing into carbon dioxide and water.

[0044] Furthermore, such as Figure 8Each of the first ultraviolet lamps 10 is hexagonal and is fixedly connected to a hexagonal frame around its perimeter. The distance between opposite sides of each hexagonal frame ranges from 0.5 to 50 cm. Thus, when a piece of protective clothing falls into the hexagonal frame, the first ultraviolet lamp 10 can irradiate the protective clothing piece more thoroughly.

[0045] Furthermore, the upper end of the treatment box 6 is fixedly connected to an exhaust pipe 11, and a filter element 12 is detachably installed at the end of the exhaust pipe 11. When exhaust gas is generated in the treatment box 6, the exhaust gas will be discharged through the exhaust pipe 11, and the filter element 12 will purify the exhaust gas and reduce the pollution of the exhaust gas to the air.

[0046] Furthermore, the inner wall of the processing box 6 is provided with a heat dissipation cavity 15, and a circulation pipe 16 is fixedly installed in the heat dissipation cavity 15. A heat dissipation circulation pump 17 is fixedly installed on the outer wall of the processing box 6. The two ends of the heat dissipation circulation pump 17 are fixedly connected to the two ends of the circulation pipe 16. During the use of the first ultraviolet lamp 10, the heat dissipation circulation pump 17 continuously circulates the condensate in the circulation pipe 16. The condensate in the circulation pipe 16 can dissipate heat for the first ultraviolet lamp 10, preventing the first ultraviolet lamp 10 from being damaged due to excessive temperature. In practice, a wind-cooled radiator can also be installed on the heat dissipation circulation pump 17 to provide air cooling for the circulation pipe 16, thereby improving the heat dissipation efficiency of the circulation pipe 16.

[0047] Furthermore, a T-shaped block 13 is fixedly connected to the lower end of the crushing box 1, and a T-shaped groove 14 is provided at the upper end of the processing box 6. The T-shaped block 13 is inserted into the T-shaped groove 14. When the processing box 6 needs to be replaced or repaired, the processing box 6 can be pulled out from the T-shaped block 13, which makes the replacement and repair of the processing box 6 more convenient.

[0048] Example 2:

[0049] Reference Figures 3-5 The implementation is basically the same as in Example 1, but with a further addition: a specific implementation plan for turning the protective clothing upside down is added.

[0050] A cylindrical rod 18 extending into the side wall of the processing box 6 is inserted therein, and a stirring rod 19 is fixedly connected to the outer wall of the cylindrical rod 18. A second ultraviolet lamp 20 with a honeycomb pattern is fixedly installed on the outer wall of the cylindrical rod 18, and a drive motor 21 is fixedly installed on the outer wall of the processing box 6. The output shaft of the drive motor 21 is connected to the cylindrical rod 18 through a reciprocating mechanism.

[0051] During the processing of protective clothing in the treatment chamber 6, the drive motor 21 and the second ultraviolet lamp 20 are turned on. The drive motor 21 drives the cylindrical rod 18 to rotate via the hexagonal rod 23. The cylindrical rod 18 drives the second ultraviolet lamp 20 and the stirring rod 19 to sweep around the circumference inside the treatment chamber 6. The second ultraviolet lamp 20 can improve the disinfection and decomposition speed of the protective clothing, while the stirring rod 19 can efficiently turn the pulverized protective clothing over, making the disinfection and decomposition speed of the protective clothing higher and more thorough. During this period, the reciprocating mechanism drives the stirring rod 19 and the second ultraviolet lamp 20 to move back and forth. The stirring rod 19 can improve the turning effect of the protective clothing, and the reciprocating movement of the second ultraviolet lamp 20 can also increase the irradiation area, thereby further improving the disinfection and degradation efficiency of the protective clothing. At the same time, the reciprocating movement of the stirring rod 19 can also reduce the probability of the protective clothing tangling.

[0052] Example 3:

[0053] Reference Figures 3-5 as well as Figure 7 Similar to Example 2, but with a further detail, a specific implementation plan for the reciprocating mechanism is disclosed.

[0054] The reciprocating mechanism includes a hexagonal hole 22 at the shaft end of the column rod 18, a hexagonal rod 23 inserted into the hexagonal hole 22, and the hexagonal rod 23 fixedly connected to the output shaft of the drive motor 21; a turntable 24 rotatably connected to the shaft end of the column rod 18, an elastic airbag 25 fixedly installed between the turntable 24 and the inner wall of the processing box 6, and a tension spring 26 fixedly installed between the inner walls of the elastic airbag 25; two symmetrically arranged rollers 27 are fixedly installed on the outer wall of the column rod 18, and the rollers 27 abut against the outer wall of the processing box 6; two symmetrically arranged protrusions 28 are fixedly connected to the outer wall of the processing box 6.

[0055] When the cylindrical rod 18 rotates, it drives the two rollers 27 to sweep circumferentially. When the rollers 27 press against the protrusion 28, they are pressed against the protrusion 28 and drive the cylindrical rod 18 to slide towards the drive motor 21. When the rollers 27 pass the protrusion 28, the elastic airbag 25 and the tension spring 26 will drive the cylindrical rod 18 to slide back to its original position under the action of elastic force. During the sliding, the hexagonal rod 23 will slide in the hexagonal hole 22 and drive the stirring rod 19 and the second ultraviolet lamp 20 to move back and forth. The stirring rod 19 can improve the folding effect of the protective clothing, and the reciprocating second ultraviolet lamp 20 can also increase the irradiation area, thereby further improving the disinfection and degradation efficiency of the protective clothing. At the same time, the reciprocating stirring rod 19 can also reduce the probability of the protective clothing getting tangled.

[0056] Example 4:

[0057] Reference Figure 1 Figure 5 as well as Figure 7The implementation is basically the same as in Example 3, but with a further addition: a specific implementation plan to prevent the stirring rod 19 from being entangled in the protective clothing is added.

[0058] An inner tube 31 is fixedly connected inside the cylindrical rod 18. An air blowing pipe 32 extending to the outer wall of the cylindrical rod 18 is fixedly connected to the inner tube 31. The end of the air blowing pipe 32 faces the outer wall of the stirring rod 19. A heat-conducting plate 33 extending into the inner tube 31 is fixedly connected to the second ultraviolet lamp 20. An air intake pipe 29 and an exhaust pipe 30 communicating with the elastic airbag 25 are fixedly connected to it. A one-way valve is fixedly installed inside both the air intake pipe 29 and the exhaust pipe 30. The end of the exhaust pipe 30 is fixedly connected to and communicates with the inner tube 31.

[0059] As the cylindrical rod 18 reciprocates, the elastic airbag 25 is intermittently compressed. When the elastic airbag 25 is compressed, it blows air into the inner tube 31 through the exhaust pipe 30. The inner tube 31 then blows air through the air blowing pipe 32, which blows off the protective clothing wrapped around the stirring rod 19. This prevents the protective clothing from getting tangled around the stirring rod 19 and also improves the hem effect of the protective clothing, resulting in better disinfection and degradation. Furthermore, as the air passes through the inner tube 31, it also carries away some of the heat from the heat-conducting plate 33, thus dissipating heat from the second ultraviolet lamp 20. The heated air entering the treatment chamber 6 further promotes the degradation of the protective clothing. When the elastic airbag 25 elastically returns to its original position, it draws in outside air through the suction pipe 29. This causes the outside air to be blown into the treatment chamber 6 through the circumferentially sweeping air blowing pipe 32, ensuring that the protective clothing receives more oxygen during degradation and increasing the degradation speed.

[0060] Furthermore, a rectangular frame 34 is fixedly connected to the outer wall of the treatment box 6. A filter plate 35 is detachably installed inside the port of the rectangular frame 34. The end of the suction pipe 29 extends into the rectangular frame 34. Air is drawn in through the suction pipe 29, and the suction pipe 29 draws air into the rectangular frame 34. The rectangular frame 34 filters out dust in the air through the filter plate 35 to prevent dust from affecting the degradation of the protective clothing.

[0061] A method for disposing of waste medical protective clothing, the operation steps are as follows:

[0062] Step 1: Dispose of the used protective suit into the disposal box 2 through the disposal port 3;

[0063] Step 2: Turn on the vacuum pump 9 to create negative pressure in the crushing chamber 1, and then turn on the electric gate 8 on the connecting pipe 4;

[0064] Step 3: The protective suit is sucked into the top of the crushing chamber 1, then the electric gate 8 in the connecting pipe 4 is closed, and the vacuum pump 9 is turned on again to put the crushing chamber 1 into a vacuum state.

[0065] Step 4: The protective suit inside the crushing box 1 is crushed by two continuously rotating crushing rollers 5;

[0066] Step 5: Open the electric gate 8 in the connecting pipe 4 again, and then open the electric gate 8 in the through slot 7;

[0067] Step 6: After the shredded protective suit falls into the processing box 6, close the two electric gates 8 and turn on the first ultraviolet lamp 10, the second ultraviolet lamp 20 and the drive motor 21.

[0068] This medical waste protective clothing processing equipment works by first dropping used protective clothing into the disposal box 2 through the disposal port 3. When degradation treatment is required, the vacuum pump 9 is turned on, creating negative pressure inside the crushing box 1. Then, the electric gate 8 on the connecting pipe 4 is opened, causing the crushing box 1 to draw air into the disposal box 2 through the connecting pipe 4. Some of the protective clothing inside the disposal box 2 is sucked into the top of the crushing box 1. Then, the electric gate 8 on the connecting pipe 4 is closed, and the vacuum pump 9 is turned on again, creating a vacuum inside the crushing box 1. The protective clothing inside the crushing box 1 is then pulverized by two continuously rotating crushing rollers 5 under vacuum. The crushing process effectively prevents the protective clothing from reacting with and oxidizing due to gases, moisture, or oxygen. The crushed protective clothing falls to the bottom of the crushing chamber 1. At this time, the electric gate 8 in the connecting pipe 4 is opened again, so that the next batch of protective clothing is sucked into the crushing chamber 1 due to the negative pressure. Then, the electric gate 8 in the channel 7 is opened, and the crushed protective clothing at the bottom of the crushing chamber 1 falls into the processing chamber 6 through the channel 7. Then, the two electric gates 8 are closed, and the first ultraviolet lamp 10 on the inner wall of the processing chamber 6 is turned on. The first ultraviolet lamp 10 will irradiate the protective clothing, which can disinfect and decompose the crushed protective clothing, realizing the in-situ harmless and volume reduction treatment of the protective clothing.

[0069] During the processing of protective clothing in the processing box 6, the drive motor 21 and the second ultraviolet lamp 20 are turned on. The drive motor 21 drives the cylindrical rod 18 to rotate through the hexagonal rod 23. The cylindrical rod 18 drives the second ultraviolet lamp 20 and the stirring rod 19 to sweep around the circumference inside the processing box 6. The second ultraviolet lamp 20 can improve the disinfection and decomposition speed of the protective clothing, and the stirring rod 19 can make the pulverized protective clothing be turned over efficiently, so that the disinfection and decomposition speed of the protective clothing is higher and more thorough.

[0070] When the cylindrical rod 18 rotates, it drives the two rollers 27 to sweep circumferentially. When the rollers 27 press against the protrusion 28, they are pressed against the protrusion 28 and drive the cylindrical rod 18 to slide towards the drive motor 21. When the rollers 27 pass the protrusion 28, the elastic airbag 25 and the tension spring 26 will drive the cylindrical rod 18 to slide back to its original position under the action of elastic force. During the sliding, the hexagonal rod 23 will slide in the hexagonal hole 22 and drive the stirring rod 19 and the second ultraviolet lamp 20 to move back and forth. The stirring rod 19 can improve the folding effect of the protective clothing, and the reciprocating second ultraviolet lamp 20 can also increase the irradiation area, thereby further improving the disinfection and degradation efficiency of the protective clothing. At the same time, the reciprocating stirring rod 19 can also reduce the probability of the protective clothing getting tangled.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
