Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and particularly relates to an integrated biological material waste collection device. Background Art

[0002] The recycling of biological material waste is a crucial link in the biosafety management system, and is widely used in medical institutions, laboratories, biopharmaceuticals, and quarantine sites to contain high-risk biological hazardous waste such as pathogenic microorganisms, chemical pollutants, and radioactive substances.

[0003] The traditional method for recycling biological material waste generally adopts an operation mode of manual bagging-tying-transferring, which has significant technical defects: Firstly, the operator needs to be in close contact with the waste bag mouth for bundling operations. If collected in this way, it is easy to cause spills, splashes, or the formation of aerosols, polluting the environment. In particular, the spillage of infectious biological agents is more likely to lead to the occurrence of biosafety accidents; Secondly, the effective volume utilization rate of the loosely stacked waste is insufficient, and the bag body is prone to rupture due to the displacement of the waste during transportation.

[0004] The above technical defects make it difficult for existing biological material waste collection devices to meet the strict requirements of biosafety laboratories above P3 level in terms of operation safety, volume efficiency, and pollution prevention and control. Therefore, the development of an integrated biosafety waste treatment equipment with intelligent sealing, dynamic sterilization, and space optimization functions has become the key technical requirement to solve the pain points of biological waste disposal.

[0005] In view of the above problems, the present invention proposes an integrated biological material waste collection device. Summary of the Invention

[0010] The vibrating compaction structure further includes: An L-shaped bracket, fixedly connecting the moving seat and the moving plate; A plurality of arc-shaped convex plates, arranged at intervals on the top of the moving plate. When the arc-shaped convex plate contacts the guiding column, it drives the detachable biosafety inner liner to vibrate. A sliding strip is provided on the inner wall of the outer protective cylinder, and a sliding groove for clearance fit with the sliding strip is provided on the outer wall of the detachable biosafety inner liner to limit the vibration track.

[0011] It further includes: A driving rod, rotatably connected to the bottom of the outer protective cylinder, with an eccentric wheel fixed to the outer wall and contacting the bottom of the detachable biosafety inner liner; A foot-operated operation pedal, fixed to one end of the driving rod, and by stepping on it, the eccentric wheel is driven to lift the detachable biosafety inner liner to the picking and placing position.

[0012] A negative pressure adsorption assembly is provided at the bottom of the outer protective cylinder, including: A negative pressure groove, hermetically and slidably connected to a piston plate; The drawstring, the fixing rod connecting the piston plate and the driving rod, generates a negative pressure adsorption force by pulling the piston plate through the reset of the driving rod. Protective covers are provided on both sides of the cover body to enclose the gear, the rack and the rotating shaft to prevent the spread of bacteria. The bottom of the rotating disc is embedded with an ultraviolet germicidal lamp. A partition plate is fixed inside the cover body to separate the biosafety film and the circumcision structure. Biosafety labels are provided on the surfaces of the biosafety film, the outer protective cylinder body and the detachable biosafety inner liner.

[0013] Advantages: 1. In the present invention, two lead screws are rotatably arranged inside the cover body. Sliding seats threadedly connected to the lead screws are slidably connected to the inner walls on both sides of the cover body that are far away from each other. The two ends of the rotating shaft respectively rotatably penetrate through the corresponding sliding seats. Two one-way bearings are sleeved on the outer wall of the rotating shaft. Gears are fixedly sleeved on the outer rings of the two one-way bearings. Racks are fixed on both sides of the cover body; the lead screw drives the rotating shaft to move through the sliding seat, and the second take-up roller pulls out the biosafety film wound on the first take-up roller until the biosafety film completely covers the top of the detachable biosafety inner liner and the waste bag inside it; conversely, after the sliding seat and the rotating shaft are reset, the biosafety film that has been cut can be wound up under the cooperation of the one-way bearing, the gear and the rack, which is convenient for pulling out the biosafety film wound well on the first take-up roller later; 2. In the present invention, a rotating disc is rotatably connected to the bottom of the disc. A plurality of fixing pins are fixed to the inner wall of the top of the disc. The plurality of fixing pins all slide on the top of the rotating disc. The outer walls of the plurality of fixing pins are slidably sleeved with the same cross beam. Cutting blades are fixed to both sides of the bottom of the cross beam. The bottom end of the pressing rod is fixedly connected to the top of the cross beam; the pressing rod drives the disc and the rotating disc to move downwards, and the rotating disc presses the biosafety film against the top of the waste bag inside the detachable biosafety inner liner, and fits the waste bag with the biosafety film. The part where the waste bag and the biosafety film are attached is heat-melted by the annular nickel-chromium heating strip at the bottom of the rotating disc to automatically complete the sealing of the waste bag opening, and then the cutting blade cuts the biosafety film; 3.

A plurality of arc-shaped convex plates are fixedly arranged on the tops of the two moving plates. The two moving plates are fixedly connected to the adjacent moving seats through L-shaped brackets on the sides far away from each other. When the moving seat drives the rotating shaft to move and covers the biosafety film on the top of the waste bag in the detachable biosafety inner container, the moving seat drives the moving plate and the arc-shaped convex plate to move through the L-shaped bracket. The cooperation of the plurality of arc-shaped convex plates and the guide posts can drive the detachable biosafety inner container to reciprocate up and down, enabling the waste in the waste bag of the detachable biosafety inner container to be compacted inside, filling the waste collection device three-quarters full, avoiding the overflow of waste from the waste bag in the detachable biosafety inner container, solving the problem of insufficient utilization rate of the effective volume due to loose accumulation of waste, and at the same time avoiding the problem of the bag body being broken due to the displacement of waste during transportation; 4. In the present invention, through the cooperation of the plugging structure and the circumcision structure, the biosafety film can be heat-melted with the waste bag in the detachable biosafety inner container, and the biosafety film can be cut off, completing the sealing of the internal waste bag of the detachable biosafety inner container by the biosafety film. The operation is simple, and it avoids the staff from being contaminated by the bacteria in the waste bag. In addition, during the movement of the moving seat and the process of covering the biosafety film on the waste bag in the detachable biosafety inner container, the detachable biosafety inner container can be driven to reciprocate up and down under the action of the compaction structure, so that the waste in the waste bag in the detachable biosafety inner container is compacted, avoiding the overflow of waste from the waste bag in the detachable biosafety inner container and affecting the sealing of the waste bag by the biosafety film.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Embodiment 1 Refer to Figure 1 、 Figure 2 、Figure 6 and Figure 11 , a waste collection device, relates to the technical field of biological waste collection devices, the waste collection device comprises a 316 stainless steel outer protective cylinder 1, the top of the outer protective cylinder 1 is fixedly connected with an ABS cover body 5 by bolts, and the outer protective cylinder 1 and the cover body 5 are connected. The top of the cover body 5 is rotatably connected with a sealing door 6 by a hinge shaft, which is convenient for closing and opening the cover body 5. A detachable biosafety liner 2 is arranged in the outer protective cylinder 1, and the top of the detachable biosafety liner 2 extends into the cover body 5. Two guide columns 3 are fixedly connected to the outer wall of the detachable biosafety liner 2, and the outer walls of the two guide columns 3 are rotatably sleeved with the same arc-shaped non-slip lifting handle 4, which is convenient for lifting the detachable biosafety liner 2.

[0018] Reference Figure 3 and Figure 5 A damping shaft 8 is rotatably connected in the cover body 5, and a reel-up roller 9 is fixedly sleeved on the outer wall of the damping shaft 8. A rotating shaft 10 is arranged in the cover body 5, and a reel-up roller 11 is fixedly sleeved on the outer wall of the rotating shaft 10. A biosafety film 12 is wound around the outer wall of the reel-up roller 19, and one end of the biosafety film 12 is fixed to the outer wall of the reel-up roller 11. The surfaces of the reel-up roller 19 and the reel-up roller 11 are coated with a silicone anti-slip layer (friction coefficient μ≥0.6).

[0019] Reference Figures 2 - 5 In order to realize the automatic covering of the biosafety film 12, a blocking structure is provided. The blocking structure includes two screw rods 18 rotating in the cover body 5, and the two screw rods 18 are located at both ends of the winding roller 9. A driving motor 19 is fixed to one side of the cover body 5 through a frame, and the output shaft of the driving motor 19 is fixedly connected to one end of one of the screw rods 18 through a coupling. The outer walls of the two screw rods 18 are fixedly sleeved with a synchronous wheel 20, and the two synchronous wheels 20 are connected by a synchronous belt 21. The inner walls of the cover body 5 on both sides away from each other are slidably connected with a moving seat 14, and the moving seat 14 is threadedly connected with the adjacent screw rod 18. The two ends of the rotating shaft 10 rotate through the corresponding moving seat 14 and extend to one side of the cover body 5 respectively. The outer wall of the rotating shaft 10 is sleeved with two one-way bearings 15, and the outer rings of the two one-way bearings 15 are fixedly sleeved with gears 16. Racks 17 are fixed on both sides of the cover body 5, and the racks 17 are meshed with the corresponding gears 16.

[0020] Specifically, when the drive motor 19 starts, through the cooperation of the synchronous belt 21 and the synchronous pulley 20, the two lead screws 18 are synchronously driven to rotate. The lead screw 18 drives the rotating shaft 10 and the second winding roller 11 to move through the moving seat 14. The gear 16 rotates under the action of the rack 17. Through the cooperation of the one-way bearing 15, at this time, the one-way bearing 15 is in an active state with the rotating shaft 10. Therefore, when the rotating shaft 10 and the moving seat 14 move, the second winding roller 11 pulls out the biosafety film 12 wound on the first winding roller 9 until the biosafety film 12 fully covers the top of the waste bag in the detachable biosafety inner liner 2 and seals the waste in the waste bag in the detachable biosafety inner liner 2. When the rotating shaft 10 and the second winding roller 11 move back to their original positions, the gear 16 rotates reversely under the action of the rack 17. The gear 16 drives the one-way bearing 15 to rotate. The one-way bearing 15 is in a locked state with the rotating shaft 10. Then the rotating shaft 10 rotates following the one-way bearing 15, and the second winding roller 11 completes the winding of the biosafety film 12 after cutting, which is convenient for pulling out the well-wound biosafety film 12 on the first winding roller 9 later. The material of the biosafety film 12 can be polyethylene (PE) or polypropylene-based reinforced composite material (PP-MPP).

[0021] Refer to Figure 1 、 Figure 3 and Figure 4 In order to further enhance the biosafety of the waste collection device, guiding and limiting chutes 13 are provided on both sides of the cover body 5, so that both ends of the rotating shaft 10 can pass through these guiding and limiting chutes 13 to rotate. At the same time, in order to prevent bacteria in the detachable biosafety inner liner 2 and the cover body 5 from spilling to the outside through the guiding and limiting chutes 13, protective covers 33 are fixedly installed on both sides of the cover body 5. These protective covers 33 can enclose and protect components such as the rack 17, the gear 16, and the rotating shaft 10, thus effectively preventing the spread of bacteria.

[0022] Refer to Figure 2 、 Figure 3 、 Figure 7 and Figure 8, To achieve the cutting of the biosafety film 12, a circumferential cutting structure is provided. The circumferential cutting structure includes a pressure rod 25 passing through the sealing door 6. A round handle is fixed to the top end of the pressure rod 25. A spring 26 is provided between the bottom of the round handle and the top of the sealing door 6, and the spring 26 is sleeved on the outer wall of the pressure rod 25. A disc 27 is sleeved on the outer wall of the pressure rod 25 and is located below the sealing door 6. The bottom of the disc 27 is rotatably connected to a rotating disc 29, which is used to press and stick the biosafety film 12 on the top of the waste bag in the detachable biosafety inner container 2. A plurality of fixing pins 28 are fixed to the inner wall of the top of the disc 27, and the plurality of fixing pins 28 all slide on the top of the rotating disc 29. The outer walls of the plurality of fixing pins 28 are slidably sleeved with the same cross beam 30. Both sides of the bottom of the cross beam 30 are fixed with cutting tools 31 (material: 440C stainless steel, hardness HRC58 - 60, cutting edge angle 30°). The bottom ends of the two cutting tools 31 both slide through the inner wall of the bottom of the disc 27. The bottom end of the pressure rod 25 is fixedly connected to the top of the cross beam 30. A circular nickel-chromium heating strip is fixed to the bottom of the rotating disc 29 (its control method and mechanism are not described in this application and are prior art).

[0023] Specifically, when it is necessary to cut the biosafety film 12, press the pressure rod 25. The pressure rod 25 compresses the spring 26 and drives the disc 27 and the rotating disc 29 to move downward through the cross beam 30. The disc 27 passes through the partition plate 7 and moves to the top of the detachable biosafety inner container 2, while the rotating disc 29 cooperates with the top of the detachable biosafety inner container 2 to press and stick the biosafety film 12 on the top of the waste bag in the detachable biosafety inner container 2, fitting the waste bag with the biosafety film 12. The part where the waste bag and the biosafety film 12 are fitted is heat-melted by the circular nickel-chromium heating strip at the bottom of the rotating disc 29, automatically completing the sealing of the waste bag mouth without manual operation, avoiding the staff from being contaminated by the bacteria in the waste bag. The pressure rod 25 continues to drive the cross beam 30 and the cutting tools 31 to move downward, and the cutting tools 31 can pierce the biosafety film 12. Then the pressure rod 25 drives the cutting tools 31 and the disc 27 to rotate through the cross beam 30, and can cut the biosafety film 12 covering the top of the detachable biosafety inner container 2, facilitating the staff to take out the sealed waste bag from the detachable biosafety inner container 2.

[0024] Refer to Figure 7 and Figure 8, Further, at the bottom of the rotating disk 29, a plurality of ultraviolet germicidal lamps 32 (wavelength 265 nm, radiation intensity ≥ 90 μW / cm² @ 1 m) are fixedly installed. The main function of these ultraviolet germicidal lamps 32 is to sterilize the waste inside the waste bag in the detachable biosafety inner liner 2, ensuring that no harmful bacteria will grow during the storage of the waste. At the same time, inside the cover body 5, a partition plate 7 is fixedly installed. The partition plate 7 is located below the disk 27 and also above the first winding roller 9 and the second winding roller 11. The setting of the partition plate 7 can effectively isolate and protect the internal mechanical structure, preventing the waste from directly contacting these key components.

[0025] Refer to Figure 3 and Figure 6 , In order to achieve the jolting and compaction of the detachable biosafety inner liner 2, a compaction structure is provided to drive the detachable biosafety inner liner 2 to reciprocate up and down, so as to compact the waste inside the detachable biosafety inner liner 2. The compaction structure includes two slidable moving plates 23 designed on the inner wall of the bottom of the cover body 5. These two moving plates 23 are respectively located on both sides of the detachable biosafety inner liner 2. At the top of each moving plate 23, a plurality of arc-shaped convex plates 24 are fixedly installed. The design of these arc-shaped convex plates 24 is to cooperate with the guide posts 3, and through their interaction, the detachable biosafety inner liner 2 can be driven to move up and down. Further, on the side where the two moving plates 23 are away from each other, L-shaped brackets 22 are fixedly installed. These L-shaped brackets 22 are fixedly connected to the adjacent moving seats 14. Therefore, when the moving seat 14 moves, it will drive the moving plate 23 to move through the L-shaped bracket 22.

[0026] The shape of the arc-shaped convex plate 24 can be: 1. Trapezoidal convex plate: Adopting a trapezoidal cross-section design with a wider top and a narrower bottom, it can increase the contact area with the guide post 3 and improve the vibration transmission efficiency; 2. Wavy convex plate: The surface is undulated in a sine wave shape, causing the detachable biosafety inner liner 2 to generate multi-directional composite vibration and enhancing the waste compaction effect.

[0027] Specifically, during the process of the moving seat 14 driving the rotating shaft 10 to move and covering the biosafety film 12 on the top of the waste bag in the detachable biosafety inner liner 2, the moving seat 14 will simultaneously drive the moving plate 23 and the arc-shaped convex plate 24 to move through the L-shaped bracket 22. At this time, the cooperation of the plurality of arc-shaped convex plates 24 and the guide posts 3 can drive the detachable biosafety inner liner 2 to reciprocate up and down. The effect of this jolting can compact the waste inside the detachable biosafety inner liner 2, thereby preventing the actual capacity of the waste bag in the detachable biosafety inner liner 2 from becoming smaller.

[0028] Refer to Figure 2 and Figure 9, on the inner wall of the outer protective cylinder body 1, a plurality of stoppers 38 are fixed, and these stoppers 38 are used to support the detachable biosafety inner liner 2. At the same time, a drive rod 34 located below the detachable biosafety inner liner 2 is rotatably connected inside the outer protective cylinder body 1. On the outer wall of the drive rod 34, a plurality of eccentric wheels 35 are fixedly sleeved, and these eccentric wheels 35 cooperate with the bottom of the detachable biosafety inner liner 2. Through the cooperation of the drive rod 34 and the eccentric wheels 35, the detachable biosafety inner liner 2 can be jacked upward. One end of the drive rod 34 rotatably extends to one side of the outer protective cylinder body 1 and is fixed with a foot-operated pedal 36. Between the outer protective cylinder body 1 and the foot-operated pedal 36, a torsion spring 41 is also fixed. This torsion spring 41 is sleeved on the outer wall of the drive rod 34 and is used to enable the foot-operated pedal 36 to reset to a vertical state when not subjected to external force.

[0029] Specifically, when dumping the waste collection device, the foot-operated pedal 36 can be stepped on to one side by the foot. At this time, the foot-operated pedal 36 will drive the eccentric wheel 35 to rotate through the drive rod 34, and the rotation of the eccentric wheel 35 will push the detachable biosafety inner liner 2 upward. When the detachable biosafety inner liner 2 is pushed to a high enough position, its top and the arc-shaped anti-slip lifting handle 4 will extend above the partition plate 7. At this time, the detachable biosafety inner liner 2 can be conveniently taken out from the outer protective cylinder body 1 and the cover body 5 for waste dumping and treatment.

[0030] Refer to Figure 2 and Figure 9 , in order to ensure that the detachable biosafety inner liner 2 can move smoothly during the upward movement and reciprocating jolting, a plurality of sliding strips 40 are also fixed on the inner wall of the outer protective cylinder body 1. Correspondingly, a plurality of sliding grooves 39 are provided on the outer wall of the detachable biosafety inner liner 2, and these sliding grooves 39 are slidably matched with the sliding strips 40. Through this sliding matching method, the movement track of the detachable biosafety inner liner 2 can be effectively restricted, so that it can maintain stability and steadiness during the upward movement and jolting.

[0031] Refer to Figure 1 , Figure 2 and Figure 9 , at the bottom on one side of the outer protective cylinder body 1, a base plate 37 is fixedly installed. The design of this base plate 37 has a dual function: on the one hand, when the foot-operated pedal 36 is stepped on and rotated to a horizontal state, the base plate 37 can stably support the foot-operated pedal 36 to ensure the safe use of the user; on the other hand, the presence of the base plate 37 effectively reduces the center of gravity of the detachable biosafety inner liner 2, making the entire outer protective cylinder body 1 more stable when placed on the ground and not easily toppled; Biosafety labels are provided on the outer protective cylinder body 1, the detachable biosafety inner liner 2, and the biosafety film 12.

[0032] In summary, through the design and implementation of the above specific embodiments, the waste bag inside the waste collection device can automatically cover and cut the biosafety film 12, and at the same time can jolt and compact the waste, improving the treatment efficiency and safety of quarantine waste. The compaction structure may include a driving device and a transmission device provided in the cover body 5, and the driving device passes through the transmission device.

[0033] Embodiment 2 Reference Figure 10 , on the basis of Embodiment 1, an improvement is made: at the bottom of the outer protective cylinder 1, a plurality of negative pressure grooves 43 are provided. A piston plate 45 is hermetically and slidably connected in each of these negative pressure grooves 43. A pulling rope 46 is fixed to the top of each piston plate 45. And between two adjacent eccentric wheels 35, a stainless steel fixing rod 42 is fixedly installed. The top ends of all the pulling ropes 46 extend into the outer protective cylinder 1 and are fixedly connected to the corresponding fixing rod 42.

[0034] Specifically, when the outer protective cylinder 1 is placed on a smooth ground, the foot-operated operation pedal 36 and the driving rod 34 can be driven to rotate. After the outer protective cylinder 1 is stably placed, the rotation of the foot-operated operation pedal 36 is released. At this time, the foot-operated operation pedal 36 will automatically reset under the action of the torsion spring 41. At the same time, the driving rod 34 will also synchronously drive the eccentric wheel 35 and the fixing rod 42 to rotate. The fixing rod 42 pulls the piston plate 45 upward through the pulling rope 46, so that a negative pressure state is formed between the piston plate 45 and the ground. This negative pressure state can firmly adsorb the outer protective cylinder 1 on the smooth ground, ensuring the stability of the placement of the outer protective cylinder 1.

[0035] In order to increase the sealing performance between the negative pressure groove 43 and the smooth ground, a silicone rubber ring 44 (Shore hardness 40±5, compression set ≤15%) is also fixedly installed in the negative pressure groove 43. This rubber ring 44 can effectively improve the sealing effect between the negative pressure groove 43 and the ground, thereby further enhancing the stability and reliability of the negative pressure adsorption.

[0036] A method for using an integrated biological material waste collection device includes the following steps: S1. Place a waste bag (a waste bag made of PP composite material that can withstand high temperatures of 135 degrees) in the detachable biosafety liner 2, and the mouth of the waste bag is placed on the outer wall of the detachable biosafety liner 2. The ultraviolet sterilization lamp 32 can sterilize the waste in the waste bag in the detachable biosafety liner 2. When it is necessary to discard the waste into the waste bag in the detachable biosafety liner 2, the waste falls into the waste bag. The ultraviolet sterilization lamp 32 can sterilize the waste that falls into the waste bag. The sealing door 6 is driven to flip through the pressure rod 25, and the cover body 5 is opened to discard the waste directly into the waste bag in the detachable biosafety liner 2. When the waste in the waste bag in the detachable biosafety liner 2 reaches three quarters of the capacity, When it is necessary to take out and send it to the designated organization for processing, the driving motor 19 synchronously drives the two screws 18 to rotate under the cooperation of the synchronous belt 21 and the synchronous wheel 20, and the screw 18 drives the rotating shaft 10 and the winding roller 2 11 to move through the moving seat 14. The gear 16 rotates under the action of the rack 17. The gear 16 cooperates with the one-way bearing 15. At this time, the one-way bearing 15 and the rotating shaft 10 are in an active state. Therefore, when the rotating shaft 10 and the moving seat 14 move, the winding roller 2 11 pulls out the biosafety film 12 wound on the winding roller 1 9 until the biosafety film 12 fully covers the detachable biosafety liner 2 and the top of the waste bag set on the top of the detachable biosafety liner 2. At this time, the biosafety film 12 covers the top of the waste bag, completing the closure of the waste bag; S2, then press the pressure rod 25, the pressure rod 25 drives the disc 27 and the rotating disc 29 to move downward through the crossbeam 30, the disc 27 passes through the isolation plate 7 and moves to the top of the detachable biosafety liner 2, and the rotating disc 29 cooperates with the top of the detachable biosafety liner 2 to press the biosafety film 12 against the top of the waste bag in the detachable biosafety liner 2, and fit the waste bag to the biosafety film 12, and the annular nickel-chromium heating strip at the bottom of the rotating disc 29 is used to heat the part where the waste bag and the biosafety film 12 fit. The pressure rod 25 then drives the crossbeam 30 and the cutting blade 31 to move downward, and the cutting blade 31 can pierce the biosafety film 12. Then, the pressure rod 25 drives the cutting blade 31 and the disc 27 to rotate through the crossbeam 30, so as to cut the biosafety film 12 covering the top of the detachable biosafety liner 2, so that the staff can take the sealed waste bag out of the detachable biosafety liner 2. S3. After the cutting blade 31 finishes cutting the biosafety film 12, the lead screw 18 rotates in the reverse direction, driving the rotating shaft 10 and the second winding roller 11 to move back to their original positions. The gear 16 rotates in the reverse direction under the action of the rack 17. The gear 16 drives the one-way bearing 15 to rotate. The one-way bearing 15 is in a locked state with the rotating shaft 10. Then, the rotating shaft 10 rotates following the one-way bearing 15, and the second winding roller 11 winds up the biosafety film 12 after cutting, facilitating the pulling out of the biosafety film 12 wound well on the first winding roller 9 in the later stage; S4. Additionally, when the moving seat 14 drives the rotating shaft 10 to move and covers the biosafety film 12 on the top of the waste bag in the detachable biosafety inner container 2, the moving seat 14 drives the moving plate 23 and the arc-shaped convex plate 24 to move through the L-shaped bracket 22. The cooperation of multiple arc-shaped convex plates 24 and the guide post 3 can drive the detachable biosafety inner container 2 to reciprocate up and down, enabling the waste in the waste bag in the detachable biosafety inner container 2 to be tamped inside, filling the waste collection device three-quarters full with waste, and preventing the waste from overflowing from the waste bag in the detachable biosafety inner container 2 and affecting the sealing of the waste bag at the top of the detachable biosafety inner container 2 by the biosafety film 12; S5. After the detachable biosafety inner container 2 is sealed and the rotating shaft 10 is reset, the pressure rod 25 drives the sealing door 6 to release the sealing of the cover body 5. Then, step on the foot-operated pedal 36 to one side with the foot. The foot-operated pedal 36 drives the eccentric wheel 35 to rotate through the driving rod 34. The eccentric wheel 35 pushes the detachable biosafety inner container 2 upward, making the top of the detachable biosafety inner container 2 and the arc-shaped anti-slip lifting handle 4 extend above the isolation board 7, facilitating the removal of the detachable biosafety inner container 2 from the outer protective cylinder 1 and the cover body 5, and then facilitating the staff to take out the waste bag encapsulated in the detachable biosafety inner container 2; S6. In addition, to ensure that the outer protective cylinder 1 is stably placed on the ground and will not tip over due to external forces, when the outer protective cylinder 1 is placed on a smooth ground, drive the foot-operated pedal 36 and the driving rod 34 to rotate. After the outer protective cylinder 1 is stably placed, release the rotation of the foot-operated pedal 36. The foot-operated pedal 36 resets under the action of the torsion spring 41, and the driving rod 34 drives the eccentric wheel 35 and the fixed rod 42 to rotate through the synchronous belt 21. The fixed rod 42 pulls the piston plate 45 upward through the pull cord 46. Then, a negative pressure state is formed between the piston plate 45 and the ground, which can adsorb the outer protective cylinder 1 on the smooth ground and ensure the stability of the placement of the outer protective cylinder 1.
