Description

Technical Field

[0001] The present invention relates to the technical field of medical waste recycling and treatment, and in particular to a medical waste recycling and treatment device for a laboratory. Background Art

[0002] The laboratory department generates a lot of medical waste every day during its work. Most of this waste is medical testing supplies contaminated with patients' blood, body fluids, excrement, etc., used cotton swabs contaminated with test reagents, disposable masks, gloves, etc., as well as various discarded specimens: sharp objects that can puncture or injure the human body, such as slides, glass slides, glass test tubes, blood collection needles, syringe needles, etc., generated during the test process. Medical staff usually directly classify and store these sharp objects in sharps boxes, and then collect and dispose of them in a unified manner.

[0003] Other waste generated during the testing process, such as medical testing supplies contaminated with patient blood, body fluids, excrement, etc., used cotton swabs contaminated with test reagents, disposable masks, gloves, etc., are usually discarded by medical staff into medical waste bins. Then, medical waste bags in the bins are regularly taken out, and after medical staff use gooseneck seals to seal the bags themselves, they are taken to the corresponding medical waste recycling station for centralized recycling and treatment;

[0004] However, patient body fluids, excrement, test reagents, etc. contaminated on cotton swabs, gauze, and disposable items are prone to emit a variety of harmful and pathogenic gases. Therefore, every time medical staff take the garbage bag out of the trash can and tie it to seal it, they need to wear tight protective clothing to avoid inhaling harmful and pathogenic gases in the trash can when opening the trash can. This makes the process of medical staff handling medical waste every day very cumbersome, and they are easily harmed by harmful and pathogenic gases in the trash can.

[0005] After searching, the Chinese patent application number CN202011472676.2 discloses a multifunctional medical waste recycling and processing equipment, including a base plate and a movable component, with four movable components rotatably provided on the base plate; a motor, and a motor is installed on the base plate. However, since the above technical solution can only compress and classify medical waste, it cannot automatically take out the garbage bags in the trash can and tie and seal them. Medical staff need to wear protective clothing before they can tie and seal the garbage bags containing medical waste by themselves, which makes the medical waste collection and processing process cumbersome and makes medical staff vulnerable to harmful gases emitted by medical waste.

[0019] Preferably, based on the above solution: a plurality of elastic telescopic rods are fixed to the outer wall of the top of the ring, and the telescopic ends of the elastic telescopic rods are fixed to the outer wall of the bottom of the mounting frame.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention can lift up the mouth of the garbage bag that is inverted on the outer wall of the garbage can through the bag mouth adjustment mechanism, and then absorb and tighten the inner wall of the bag mouth of the garbage bag through the bag mouth adsorption and fixing mechanism, while absorbing the harmful gas inside the garbage bag. Subsequently, when the garbage bag is lifted out of the inner wall of the garbage can body, the bag mouth of the garbage bag that is adsorbed and fixed is driven to rotate, thereby automatically twisting the bag mouth of the garbage bag into a spiral strip shape, and then automatically completing the gooseneck knotting and sealing work of the bag mouth of the garbage bag that has been twisted into a spiral strip through the knotting and sealing mechanism, so that medical staff only need to place the garbage can body on the mobile rack to automatically complete the knotting and sealing work of the garbage bag, thereby avoiding the medical staff from contacting with harmful gases and substances inside the garbage bag, and improving the efficiency of medical waste recycling and treatment.

[0022] 2. Before the knotting and sealing mechanism on one side of the mounting rod folds and knots the spirally twisted bag opening, the PLC controller controls the second electric push rod to continue pushing the connecting plate upward to a corresponding height, thereby pulling the garbage bag body upward by a corresponding distance through the first connecting rod and the second connecting rod clamped on the outer wall of the garbage bag body, so that the spirally twisted bag opening of the garbage bag is no longer tight and forms a certain fold and bend. Subsequently, when the mounting rod moves forward, the curved spirally twisted bag opening can be quickly folded and knotted to seal, thereby avoiding the problem of the spirally twisted bag opening being overly tight and affecting the folding and knotting of the bag opening.

[0023] 3. When the inner wall of the garbage bag is attached to the opening at one end of the suction pipe, the suction pipe will be blocked and sealed. At this time, the negative pressure inside the sealing cover will absorb the gas inside the cylinder through the air guide line between the first air guide interface and the second air guide interface, so that the output end of the cylinder drives the mounting frame to move downward by a corresponding distance. When the mounting frame moves downward, it will drive the gears engaged with it to rotate clockwise through the multiple racks fixed at the bottom, thereby driving the rotating rod and the sealing cover to rotate downward, so that the sealing cover is clamped on the outside of the garbage bag attached to the outer wall of the arc cover, thereby cooperating with the arc cover to clamp and fix the bag opening of the garbage bag.

[0024] 4. The PLC controller controls the electric slide rail on the inner wall of the first guide plate to drive the movable plate to move upward and reset as a whole. When the external threaded tube moves upward, the inner wall of the internal threaded sleeve will drive the external threaded tube to rotate through the thread, thereby driving the bag opening of the garbage bag clamped on the outer wall of the arc cover to rotate. While the garbage bag is lifted out of the inner wall of the garbage can body, the bag opening of the garbage bag is screwed.

[0025] 5. When the second electric push rod pushes the connecting plate to move upward, and the opening of the garbage bag upside down on the outer wall of the trash can body is lifted up through the first connecting rod and the second connecting rod, the air bag on the top will be continuously squeezed, so that the gas inside the air bag will rush into the jet head and be sprayed toward the outer wall of the trash can body through the jet head, blowing the opening of the garbage bag close to the outer wall of the trash can body away from the outer wall of the trash can body, so that the continuously upward moving roller can stably lift the opening of the garbage bag upward.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0037] The following describes embodiments of the present invention in detail.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Example 1:

[0039] A medical waste recycling and processing device for a laboratory Figure 1-9 As shown, it includes a collection box 1, the top outer wall of the collection box 1 is provided with a reserved through groove 7, the top outer wall of the collection box 1 is fixed with a group of slide grooves 6, the outer wall of one side of the collection box 1 is connected with a sealed door by a hinge, the inner wall of the slide groove 6 is slidably connected with a movable frame 5 by an electric slide rail, the top outer wall of the collection box 1 is fixed with an L-shaped plate 15, the top outer wall of the L-shaped plate 15 is fixed with a first guide plate 11, the inner wall of the first guide plate 11 is slidably connected with a movable plate 13 by an electric slide rail, the inner wall of the movable plate 13 is rotatably connected with an externally threaded tube 12, the top inner wall of the L-shaped plate 15 is fixed with an internally threaded sleeve 23, the externally threaded tube 12 is connected to the inner wall of the internally threaded sleeve 23 by threads, the bottom end of the externally threaded tube 12 is fixed with a circular ring 22, and the outer wall of the circular ring 22 is provided with a bag mouth adsorption fixing mechanism;

[0040] A second electric push rod 18 is fixed to the outer wall of one side of the L-shaped plate 15, and a connecting plate 20 is fixed to the telescopic end of the second electric push rod 18. The connecting plate 20 is slidably connected to the outer wall of one side of the L-shaped plate 15, and a bag opening adjustment mechanism is provided on the outer wall of one side of the connecting plate 20;

[0041] The outer wall of the L-shaped plate 15 is fixed with a second guide plate 16, and the outer wall of one side of the second guide plate 16 is slidably connected to a mounting rod 28 through an electric slide rail, and the outer wall of the mounting rod 28 is provided with a knotting and sealing mechanism;

[0042] A first support plate 10 is fixed to the outer wall of one side of the L-shaped plate 15, a first electric push rod 9 is fixed to the outer wall of the bottom of the first support plate 10, a pressure plate 19 is fixed to the output shaft of the first electric push rod 9, and the pressure plate 19 is slidably connected to the outer wall of the L-shaped plate 15 and the second electric push rod 18, and a push plate 8 is fixed to the outer wall of the bottom of the movable frame 5;

[0043] A shielding cover 3 is fixed to the outer wall of the top of the collection box 1, a PLC controller 2 is fixed to the outer wall of one side of the shielding cover 3, and the first electric push rod 9, the second electric push rod 18 and multiple electric slide rails are electrically connected to the PLC controller 2 respectively.

[0044] In this embodiment, the trash can body 4 is a pedal-type trash can commonly used in hospitals.

[0045] When medical staff need to seal and recycle the garbage bags containing medical waste inside the garbage can body 4, they only need to push the collection box 1 to the side of the garbage can body 4, and then place the garbage can body 4 on the movable frame 5 with the pedal facing the opening of the shielding cover 3. Then, the PLC controller 2 controls the electric slide rail on the inner wall of the slide 6 to drive the movable frame 5 to move a corresponding distance into the shielding cover 3 as a whole, so that the pressing plate 19 moves to the top of the pedal on one side of the garbage can body 4. Then, the PLC controller 2 controls the first electric push rod 9 to push the pressing plate 19 downward, and the pedal on one side of the garbage can body 4 is pressed downward by the first electric push rod 9 to open the cover on the top of the garbage can body 4.

[0046] Then the PLC controller 2 will control the second electric push rod 18 to push the connecting plate 20 to move upward a corresponding distance as a whole, so that the bag opening of the garbage bag buckled on the outer wall of the garbage bin body 4 will be lifted up through the bag opening adjustment mechanism on one side of the connecting plate 20. At the same time, the PLC controller 2 will control the electric slide rail on one side of the first guide plate 11 to drive the movable plate 13 to move downward as a whole. When the movable plate 13 moves downward, it will drive the external threaded tube 12 to move downward as a whole through the thread under the guidance of the internal threaded sleeve 23, so that the ring 22 will move as a whole to the inside of the lifted garbage bag bag opening. Figure 4 As shown, at this time, the outer wall of the ring 22 moves to the inside of the lifted bag opening, and the bag opening adsorption and fixing mechanism adsorbs and fixes the inner wall of the garbage bag opening. Then, the PLC controller 2 controls the electric slide rail on one side of the first guide plate 11 to drive the external threaded tube 12 to move upward as a whole and reset;

[0047] At this time, the external threaded tube 12 moving upward will rotate under the drive of the inner wall thread of the internal threaded sleeve 23, thereby driving the bag opening adsorption and fixing mechanism on the outer wall of the ring 22 to rotate, while lifting the entire garbage bag from the inner wall of the garbage can body 4. At the same time, by driving the bag opening of the garbage bag to shrink and rotate, the lower side of the bag opening of the garbage bag is twisted into a spiral strip shape. At this time, the part of the bottom of the garbage bag containing medical waste will continue to move upward under the guidance and limit of the inner wall of the garbage can body 4, preventing the bottom of the garbage bag from rotating with the bag opening;

[0048] like Figure 5 After the outer threaded tube 12 moves upward to the initial position, the bottom of the garbage bag will also move into the bag opening adjustment mechanism on the side of the connecting plate 20. At this time, the PLC controller 2 will control the bag opening adjustment mechanism to clamp and limit the bottom of the garbage bag, and at the same time control the second electric push rod 18 to continue to push the connecting plate 20 upward to a corresponding height, and lift the garbage bag body upward by a corresponding distance through the bag opening adjustment mechanism clamped on the outer wall of the garbage bag body, so that the bag opening of the garbage bag twisted into a spiral strip is no longer tightened and forms a certain fold bend, and then control the electric slide rail on one side of the second guide plate 16 to drive the mounting rod 28 to move forward, so that the bag opening twisted into a spiral strip is folded and knotted by the knotting sealing mechanism on the outer wall of the mounting rod 28, so that the bag opening of the garbage bag is completed with a gooseneck knot sealing, and then the PLC controller 2 controls the electric slide rail on the inner side of the slide groove 6 to drive the movable frame 5 to move back and reset, so that the garbage bin body 4 after the garbage bag is taken out is moved out of the side of the shielding cover 3, and the medical staff can remove the garbage bin body 4 and re-bag it.

[0049] After the garbage bag is collected by the garbage collector 1, the garbage collector 1 can collect the garbage from the garbage bin 1 and the garbage bag will be collected by the garbage collector 1.

[0050] The present invention can lift up the mouth of the garbage bag that is inverted on the outer wall of the garbage can through the bag mouth adjustment mechanism, and then adsorb and tighten the inner wall of the bag mouth of the garbage bag through the bag mouth adsorption and fixing mechanism, while absorbing the harmful gases inside the garbage bag. Then, when the garbage bag is lifted out of the inner wall of the garbage can body 4, the adsorbed and fixed bag mouth of the garbage bag is driven to rotate, thereby automatically twisting the bag mouth of the garbage bag into a spiral strip shape, and then automatically completing the gooseneck knotting and sealing work of the bag mouth of the garbage bag that has been twisted into a spiral strip through the knotting and sealing mechanism, so that medical staff only needs to place the garbage can body 4 on the mobile rack 5 to automatically complete the knotting and sealing work of the garbage bag, avoiding the medical staff from contacting with harmful gases and substances inside the garbage bag, while improving the efficiency of medical waste recycling and treatment.

[0051] like Figure 4-6 As shown, the bag opening adjustment mechanism includes a third electric push rod 34, a first connecting rod 26, a second connecting rod 29 and a roller 25. The third electric push rod 34 is fixed to an outer wall of one side of the connecting plate 20, the second connecting rod 29 is fixed to an outer wall of one side of the third electric push rod 34, the first connecting rod 26 is fixed to the output shaft of the third electric push rod 34, and multiple rollers 25 are rotatably connected to the top outer walls of the first connecting rod 26 and the second connecting rod 29 respectively. The third electric push rod 34 is electrically connected to the PLC controller 2;

[0052] When the second electric push rod 18 drives the connecting plate 20 to move upward as a whole, the first connecting rod 26 and the second connecting rod 29 will move upward at the same time, thereby pushing the garbage bag opening buckled on the outer wall of the trash can body 4 upward by rotating the multiple rollers 25 connected to the top of the first connecting rod 26 and the second connecting rod 29. When the ring 22 rotates to screw the bag opening through the bag opening adsorption and fixing mechanism on the outer wall, the PLC controller 2 will control the third electric push rod 34 to drive the first connecting rod 26 that moves upward and away from the top opening of the trash can body 4 to move toward the side of the second connecting rod 29, thereby continuously moving upward through the first connecting rod 26 and the second connecting rod 29. The garbage bag body is clamped and limited, and before the knotting and sealing mechanism on one side of the mounting rod 28 folds and knots the spiral-shaped bag opening, the PLC controller 2 will control the second electric push rod 18 to continue pushing the connecting plate 20 to move upward to a corresponding height, thereby pulling the garbage bag body upward to a corresponding distance through the first connecting rod 26 and the second connecting rod 29 clamped on the outer wall of the garbage bag body, so that the bag opening twisted into a spiral strip is no longer tightened and forms a certain fold and bend. Subsequently, when the mounting rod 28 moves forward, the curved spiral strip bag opening can be quickly folded and knotted to seal, thereby avoiding the problem that the spiral strip bag opening is excessively tight and affects the folding and knotting of the bag opening.

[0053] like Figure 3-8As shown, the bag opening adsorption and fixing mechanism includes an air pump 27, a metal air guide tube 47, a sealing cover 38, an air suction pipe 37, a curved cover 31, a first air guide interface 39, a cylinder 40, a mounting frame 42, a rack 43, a rotating rod 46, a gear 45, a sealing cover plate 30 and a second air guide interface 44. The air pump 27 is fixed to the top outer wall of the movable plate 13, the metal air guide tube 47 is connected to the air extraction end of the air pump 27, the metal air guide tube 47 passes through the inner wall of the external threaded tube 12, the inner wall of the sealing cover 38 is rotatably connected to the bottom end of the metal air guide tube 47 through a sealing bearing, a plurality of air suction pipes 37 pass through the outer wall of one side of the sealing cover 38, the curved cover 31 is fixed on the outer wall of the air suction pipe 37, and one end of the air suction pipe 37 passes through the outer wall of one side of the curved cover 31;

[0054] The plurality of cylinders 40 are fixed on the top outer wall of the ring 22, the first air guide interface 39 is plugged into the outer wall of the sealing cover 38, the second air guide interface 44 is connected to the input end of the cylinder 40 through the air guide pipeline, the rotating rod 46 is rotatably connected to the bottom outer wall of the ring 22, the sealing cover plate 30 is fixed on the outer wall of one side of the rotating rod 46, the gear 45 is fixed on the outer wall of one side of the rotating rod 46, the rack 43 is fixed on the outer wall of the mounting bracket 42, and the rack 43 and the gear 45 are meshed and linked.

[0055] When the PLC controller 2 controls the electric slide rail on the inner wall of the chute 6 to drive the trash can body 4 to move into the shielding cover 3, the PLC controller 2 will control the electric slide rail on the inner wall of the first guide plate 11 to drive the movable plate 13 to move downward as a whole, so that the ring 22 moves to the bag opening of the garbage bag as a whole. Then the PLC controller 2 controls the air pump 27 to operate, and the metal air guide tube 47 is used to evacuate the inner wall of the sealing cover 38 to generate negative pressure inside the sealing cover 38, so that the multiple suction pipes 37 plugged into the outer wall of the sealing cover 38 adsorb the inner wall of the bag opening of the garbage bag after being lifted by the bag opening adjustment mechanism, so that the bag opening of the garbage bag gathers and fits tightly against the outer wall of the arc cover 31. When the inner wall of the bag is attached to the opening of one end of the suction pipe 37, the suction pipe 37 will be blocked and sealed. At this time, the negative pressure inside the sealing cover 38 will absorb the gas inside the cylinder 40 through the air guide line between the first air guide interface 39 and the second air guide interface 44, so that the output end of the cylinder 40 drives the mounting frame 42 to move downward by a corresponding distance. When the mounting frame 42 moves downward, it drives the gear 45 meshing with it to rotate clockwise through the multiple racks 43 fixed at the bottom, thereby driving the rotating rod 46 and the sealing cover plate 30 to rotate downward, so that the sealing cover plate 30 is clamped on the outside of the garbage bag attached to the outer wall of the arc cover 31, thereby cooperating with the arc cover 31 to clamp and fix the bag opening of the garbage bag;

[0056] Then the PLC controller 2 controls the electric slide rail on the inner wall of the first guide plate 11 to drive the movable plate 13 to move upward and reset as a whole. When the external threaded tube 12 moves upward, the inner wall of the internal threaded sleeve 23 drives the external threaded tube 12 to rotate through the thread, thereby driving the bag opening of the garbage bag clamped on the outer wall of the arc cover 31 to rotate. While the garbage bag is lifted out of the inner wall of the garbage can body 4, the bag opening of the garbage bag is screwed.

[0057] In this embodiment, a corresponding pressure relief valve or other valve body with a pressure relief effect can be provided at the bottom of the sealing cover 38 to avoid the problem of excessive negative pressure inside the sealing cover 38 and improve the safety of the device during use.

[0058] like Figure 6 As shown, the knotting and sealing mechanism includes a movable block 36, a handheld cable tie machine 35, an elliptical rod 33 and a limiting ring 32. The movable block 36 is slidably connected to the outer wall of the mounting rod 28 through an electric slide rail. The handheld cable tie machine 35 is arranged on the inner wall of the movable block 36. The elliptical rod 33 is fixed to one end of the mounting rod 28. A set of limiting rings 32 is fixed to the outer wall of the elliptical rod 33.

[0059] When the ring 22 moves upward and resets under the drive of the external threaded tube 12, the PLC controller 2 will control the electric slide rail on one side of the second guide plate 16 to drive the mounting rod 28 to move forward as a whole, so that the elliptical rod 33 on one side of the mounting rod 28 squeezes and folds the spiral strip of the garbage bag. When the mounting rod 28 moves forward a corresponding distance, the spiral strip at the bottom of the bag opening of the garbage bag will be folded under the squeeze of the elliptical rod 33. Then the PLC controller 2 will control the electric slide rail on the outer wall of the mounting rod 28 to drive the handheld cable tie machine 35 to move forward, so that the handheld cable tie machine 35 can fix the folded part of the garbage bag body with a tie, thereby completing the gooseneck sealing of the garbage bag.

[0060] Then the PLC controller 2 controls the electric slide rail to drive the movable block 36 and the mounting rod 28 to reset, and at the same time controls the air pump 27 to stop running, thereby releasing the negative pressure adsorption on the bag mouth of the garbage bag. At this time, the garbage bag after the gooseneck knot can fall into the collection box 1 by its own gravity, thereby automatically completing the recycling of the garbage bag.

[0061] like Figure 3-5As shown, a second support plate 21 is fixed to the outer wall of one side of the L-shaped plate 15, and an airbag 17 is fixed to the outer wall of the bottom of the second support plate 21. The outer wall of the bottom of the airbag 17 is fixed to the outer wall of the top of the connecting plate 20, and a plurality of nozzles 24 are fixed to the outer wall of the top of the first connecting rod 26 and the second connecting rod 29. The nozzles 24 are connected to the airbag 17 through an air guide pipe; when the second electric push rod 18 pushes the connecting plate 20 to move upward, the opening of the garbage bag upside down on the outer wall of the trash can body 4 is lifted up through the first connecting rod 26 and the second connecting rod 29, the airbag 17 on the top is continuously squeezed, so that the gas inside the airbag 17 rushes into the nozzles 24 and is sprayed toward the outer wall of the trash can body 4 through the nozzles 24, thereby blowing the opening of the garbage bag close to the outer wall of the trash can body 4 away from the outer wall of the trash can body 4, so that the continuously upward moving roller 25 can stably lift the opening of the garbage bag upward.

[0062] like Figure 2-4 As shown, an activated carbon filter box 14 is fixed to the top outer wall of the L-shaped plate 15, and the output end of the air pump 27 is connected to the input end of the activated carbon filter box 14 through an air guide pipe; the gas in the garbage bag absorbed by the air pump 27 will be transported to the activated carbon filter box 14 through the pipeline, and will be discharged outside the device after being filtered and purified by the activated carbon filter box 14.

[0063] When the present embodiment is in use, the collection box 1 is pushed to the side of the trash can body 4, and then the trash can body 4 is placed on the movable frame 5 at an angle with the pedal facing the opening of the shielding cover 3. The PLC controller 2 controls the electric slide rail on the inner wall of the slide 6 to drive the movable frame 5 to move a corresponding distance into the shielding cover 3 as a whole, so that the pressing plate 19 moves to the top of the pedal on the side of the trash can body 4. Then, the PLC controller 2 controls the first electric push rod 9 to push the pressing plate 19 downward, and the pedal on the side of the trash can body 4 is pressed downward by the first electric push rod 9 to open the cover on the top of the trash can body 4.

[0064] Then the PLC controller 2 controls the second electric push rod 18 to push the connecting plate 20 upwards by a corresponding distance, and the bag opening adjustment mechanism on one side of the connecting plate 20 lifts up the bag opening of the garbage bag buckled on the outer wall of the garbage bin body 4. At the same time, the PLC controller 2 controls the electric slide rail on the side of the first guide plate 11 to drive the movable plate 13 to move downwards as a whole. When the movable plate 13 moves downwards, it drives the external threaded tube 12 to move downwards as a whole through the thread under the guidance of the internal threaded sleeve 23, so that the ring 22 moves as a whole to the inside of the lifted bag opening of the garbage bag. Figure 4 As shown, at this time, the outer wall of the ring 22 moves to the inside of the lifted bag opening, and the bag opening adsorption and fixing mechanism adsorbs and fixes the inner wall of the garbage bag opening. Then, the PLC controller 2 controls the electric slide rail on one side of the first guide plate 11 to drive the external threaded tube 12 to move upward as a whole and reset;

[0065] When moving upward, the external threaded tube 12 will rotate under the drive of the inner wall thread of the internal threaded sleeve 23, driving the bag opening adsorption and fixing mechanism on the outer wall of the ring 22 to rotate, while lifting the garbage bag from the inner wall of the garbage bin body 4, by driving the bag opening of the garbage bag to contract and rotate, the lower side of the bag opening of the garbage bag is twisted into a spiral strip shape. At this time, the part of the bottom of the garbage bag containing medical waste will continue to move upward under the guidance and limit of the inner wall of the garbage bin body 4, preventing the bottom of the garbage bag from rotating with the bag opening;

[0066] like Figure 5 After the outer threaded tube 12 moves upward to the initial position, the bottom of the garbage bag will also move into the bag opening adjustment mechanism on the side of the connecting plate 20. At this time, the PLC controller 2 will control the bag opening adjustment mechanism to clamp and limit the bottom of the garbage bag, and at the same time control the second electric push rod 18 to continue to push the connecting plate 20 upward to a corresponding height, and lift the garbage bag body upward by a corresponding distance through the bag opening adjustment mechanism clamped on the outer wall of the garbage bag body, so that the bag opening of the garbage bag twisted into a spiral strip is no longer tightened and forms a certain fold bend. Then, the electric slide rail on one side of the second guide plate 16 is controlled to drive the mounting rod 28 to move forward, and the knotting sealing mechanism on the outer wall of the mounting rod 28 folds and knots the twisted spiral strip bag opening, completing the gooseneck knot sealing of the garbage bag opening. Then, the PLC controller 2 controls the electric slide rail inside the slide groove 6 to drive the movable frame 5 to move back and reset, thereby moving the garbage bin body 4 after taking out the garbage bag out of the side of the shielding cover 3. At this time, the medical staff can remove the garbage bin body 4 and re-bag it.

[0067] Then the PLC controller 2 will control the bag mouth adsorption and fixing mechanism on the outer wall of the ring 22 to release the adsorption and fixing of the bag mouth of the garbage bag. At this time, the garbage bag after knotting and sealing can fall by its own gravity, and pass through the reserved groove 7 on the top of the collection box 1 and fall into the collection box 1 for recycling. After the medical staff pushes the collection box 1 to recycle the garbage bags in all the garbage cans inside the department, the collection box 1 can be pushed to the corresponding medical waste centralized recycling point. After opening the sealed door on one side of the collection box 1, the multiple garbage bags inside the collection box 1 that have been knotted and sealed can be taken out and put into the garbage recycling point.

[0068] Example 2:

[0069] A medical waste recycling and processing device for a laboratory Figure 7-8As shown, this embodiment makes the following improvements on the basis of embodiment 1: a plurality of elastic telescopic rods 41 are fixed to the top outer wall of the circular ring 22, and the telescopic ends of the elastic telescopic rods 41 are fixed to the bottom outer wall of the mounting bracket 42; when the PLC controller 2 controls the air pump 27 to stop running, the negative pressure inside the sealing cover 38 will disappear, and the mounting bracket 42 will move upward and reset under the elastic force of the elastic telescopic rods 41, thereby driving the rack 43 to move upward and reset through the mounting bracket 42, and when the rack 43 moves upward, it will drive the gear 45 to rotate counterclockwise, thereby driving the rotating rod 46 and the sealing cover plate 30 to rotate outward by a corresponding angle and then reset, so that the bag opening adsorption and fixing mechanism is ready to adsorb and fix the bag opening of the next garbage bag.

[0070] When this embodiment is in use, when the PLC controller 2 controls the air pump 27 to stop running, the negative pressure inside the sealing cover 38 will disappear. At this time, the mounting bracket 42 will move upward and reset under the elastic force of the elastic telescopic rod 41, and the rack 43 will be driven to move upward and reset through the mounting bracket 42. When the rack 43 moves upward, it will drive the gear 45 to rotate counterclockwise, and drive the rotating rod 46 and the sealing cover plate 30 to rotate outward by a corresponding angle and then reset.
