Description
Technical Field
[0001] The present invention relates to the technical field of waste treatment, and in particular to an integrated biomaterial waste collection device. Background Art
[0002] Biomaterial waste recycling is a vital link in the biosafety management system and is widely used in medical institutions, laboratories, biopharmaceuticals and quarantine sites to contain high-risk biohazardous waste containing pathogenic microorganisms, chemical pollutants, radioactive substances, etc.
[0003] The traditional method of recycling biomaterial waste generally adopts the manual bagging-tying-transfer operation mode, which has significant technical defects: first, the operator needs to be in close contact with the waste bag mouth to perform the tying operation. If this method is used for collection, it is easy to cause spillage, splashing or aerosol formation, causing pollution to the environment, especially the spillage of infectious biological factors is more likely to cause biosafety accidents; second, the effective volume utilization rate of loosely stacked waste is insufficient, and the bag body is easily broken due to the displacement of waste during transportation.
[0004] These technical deficiencies make it difficult for existing biomaterial waste collection devices to meet the stringent requirements of P3-level biosafety laboratories and above in terms of operational safety, volumetric efficiency, and pollution prevention and control. Therefore, the development of integrated biosafety waste treatment equipment with intelligent sealing, dynamic sterilization, and space optimization capabilities has become a key technical need to address the pain points of biowaste disposal.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0050] Example 1
[0051] Reference 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 includes a 316 stainless steel outer protective cylinder 1, the top of the outer protective cylinder 1 is fixedly connected to 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 to a sealing door 6 through a hinge, 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.
[0052] Reference Figure 3 and Figure 5A damping shaft 8 is rotatably connected within the cover 5. A reel-up roller 9 is fixedly mounted on the outer wall of the damping shaft 8. A rotating shaft 10 is disposed within the cover 5. A reel-up roller 11 is fixedly mounted on the outer wall of the rotating shaft 10. A biosafety film 12 is wound around the outer wall of reel-up roller 11, one end of which is fixed to the outer wall of reel-up roller 11. Both reel-up roller 11 and reel-up roller 11 are coated with a silicone anti-slip layer (friction coefficient μ ≥ 0.6).
[0053] Reference Figure 2-Figure 5 In order to achieve automatic covering of the biosafety membrane 12, a blocking structure is provided. The blocking structure includes two screws 18 that rotate within the cover body 5, and the two screws 18 are located at both ends of the winding roller 9. A drive motor 19 is fixed to one side of the cover body 5 through a frame, and the output shaft of the drive motor 19 is fixedly connected to one end of one of the screws 18 via a coupling. The outer walls of both screws 18 are fixedly sleeved with a synchronous pulley 20, and the two synchronous pulleys 20 are connected to each other by a synchronous belt 21. The inner walls of the cover body 5 on both sides away from each other are slidably connected to a movable seat 14, and the movable seat 14 is threadedly connected to the adjacent screws 18. The two ends of the rotating shaft 10 rotate through the corresponding movable seat 14 and extend to one side of the cover body 5. 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 a gear 16. Racks 17 are fixed to both sides of the cover body 5, and the racks 17 mesh with the corresponding gears 16.
[0054] Specifically, when the drive motor 19 is started, the two screws 18 are synchronously driven to rotate through the cooperation of the synchronous belt 21 and the synchronous wheel 20. The screws 18 drive the rotating shaft 10 and the reel-2 11 to move through the movable 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 movable seat 14 move, the reel-2 11 pulls out the biosafety film 12 wound on the reel-1 9 until the biosafety film 12 completely covers the top of the waste bag in the detachable biosafety liner 2, thereby sealing the waste in the waste bag in the detachable biosafety liner 2. When the rotating shaft 10 and the winding roller 2 11 are reset and moved, the gear 16 rotates in the opposite direction under the action of the rack 17, and the gear 16 drives the one-way bearing 15 to rotate. The one-way bearing 15 and the rotating shaft 10 are in a locked state, and then the rotating shaft 10 rotates following the one-way bearing 15. The winding roller 2 11 completes the winding of the biosafety film 12 after cutting, which is convenient for pulling out the biosafety film 12 that is intactly wound on the winding roller 1 9 later. The material of the biosafety film 12 can be polyethylene (PE) or polypropylene-based reinforced composite material (PP-MPP).
[0055] Reference Figure 1 、 Figure 3 and Figure 4To further enhance the biosafety of the waste collection device, guide and limit slots 13 are provided on both sides of the cover 5, allowing the two ends of the rotating shaft 10 to rotate through these guide and limit slots 13. Furthermore, to prevent bacteria within the removable biosafety liner 2 and the cover 5 from escaping through the guide and limit slots 13, protective shields 33 are fixedly installed on both sides of the cover 5. These shields 33 provide a sealed and protective barrier around components such as the rack 17, gear 16, and rotating shaft 10, effectively preventing the spread of bacteria.
[0056] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8 To achieve the cutting of the biosafety membrane 12, a circular cutting structure is provided. This structure comprises a pressure rod 25 that extends through the sealing door 6. A round handle is fixed to the top of the pressure rod 25. A spring 26 is positioned between the bottom of the handle and the top of the sealing door 6, and the spring 26 is sleeved onto the outer wall of the pressure rod 25. The outer wall of the pressure rod 25 is sleeved with a circular disc 27 located below the sealing door 6. The bottom of the circular disc 27 is rotatably connected to a rotating disc 29, which is used to press the biosafety membrane 12 against the top of the waste bag within the removable biosafety liner 2. Multiple fixing pins 28 are fixed to the top inner wall of the circular disc 27, and each of the fixing pins 28 slides on the top of the rotating disc 29. The outer walls of the fixing pins 28 slide around a common crossbeam 30. Cutting blades 31 (made of 440C stainless steel, hardness HRC 58-60, blade angle 30°) are fixed to both sides of the bottom of the crossbeam 30. The bottom ends of the two cutting blades 31 slide through the bottom inner wall of the circular disc 27. The bottom end of the pressure rod 25 is fixedly connected to the top of the crossbeam 30, and an annular nickel-chromium heating strip is fixed to the bottom of the rotating disk 29 (its control method and mechanism will not be repeated in this application and are prior art).
[0057] Specifically, when the biosafety film 12 needs to be cut, the pressure rod 25 is pressed, and the pressure rod 25 compresses the spring 26 and drives the disc 27 and the rotating disc 29 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, fitting the waste bag to the biosafety film 12. The annular nickel-chromium heating strip at the bottom of the rotating disc 29 is used to heat-seal the part where the waste bag and the biosafety film 12 fit together, automatically completing the sealing of the waste bag opening without manual operation, thus preventing workers from being contaminated by bacteria in the waste bag. The pressure rod 25 continues to drive the crossbeam 30 and the cutting blade 31 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, which can cut the biosafety film 12 covering the top of the detachable biosafety liner 2, making it easier for the staff to remove the encapsulated waste bag from the detachable biosafety liner 2.
[0058] Reference Figure 7 and Figure 8 Furthermore, multiple ultraviolet germicidal lamps 32 (wavelength 265nm, radiation intensity ≥90μW / cm²@1m) are fixedly embedded at the bottom of the rotating disk 29. The primary function of these ultraviolet germicidal lamps 32 is to sterilize the waste inside the waste bag within the removable biosafety liner 2, ensuring that harmful bacteria do not grow during storage. Simultaneously, an isolation plate 7 is fixedly installed within the cover 5. This isolation plate 7 is located below the disk 27 and above the winding rollers 1 9 and 2 11. The provision of the isolation plate 7 effectively isolates and protects the internal mechanical structure, preventing waste from directly contacting these key components.
[0059] Reference Figure 3 and Figure 6 In order to achieve the shaking and compaction of the detachable biosafety liner 2, a compaction structure is provided to drive the detachable biosafety liner 2 to shake back and forth up and down, so that the waste in the detachable biosafety liner 2 is compacted. The compaction structure includes two sliding movable plates 23 designed on the bottom inner wall of the cover body 5, and the two movable plates 23 are respectively located on both sides of the detachable biosafety liner 2. A plurality of arc-shaped protrusions 24 are fixed on the top of each movable plate 23. These arc-shaped protrusions 24 are designed to cooperate with the guide column 3, and through their interaction, the detachable biosafety liner 2 can be driven to move up and down. Furthermore, L-shaped brackets 22 are fixed on the side where the two movable plates 23 are away from each other. These L-shaped brackets 22 are fixedly connected to the adjacent movable seat 14. Therefore, when the movable seat 14 moves, it will drive the movable plate 23 to move through the L-shaped bracket 22.
[0060] The shapes of the arc-shaped convex plate 24 can be: 1. Trapezoidal convex plate: adopting a trapezoidal cross-section design that is wide at the top and narrow at the bottom can increase the contact area with the guide column 3 and improve the vibration transmission efficiency; 2. Wave-shaped convex plate: the surface is undulating in a sinusoidal wave shape, causing the detachable biosafety liner 2 to produce multi-directional composite vibration, thereby enhancing the waste compaction effect.
[0061] Specifically, as the movable base 14 drives the rotating shaft 10 to move, placing the biosafety film 12 over the top of the waste bag within the removable biosafety liner 2, the movable base 14 simultaneously drives the movable plate 23 and the curved protruding plate 24 via the L-shaped bracket 22. At this point, the multiple curved protruding plates 24 cooperate with the guide post 3 to drive the removable biosafety liner 2 to rock back and forth. This rocking effect compacts the waste within the removable biosafety liner 2, thereby preventing the actual volume of the waste bag within the removable biosafety liner 2 from being reduced.
[0062] Reference Figure 2 and Figure 9 , a plurality of blocks 38 are fixed on the inner wall of the outer protective cylinder 1, and these blocks 38 are used to support the detachable biosafety liner 2. At the same time, a driving rod 34 located below the detachable biosafety liner 2 is rotatably connected in the outer protective cylinder 1. On the outer wall of the driving rod 34, a plurality of eccentric wheels 35 are fixedly sleeved, and these eccentric wheels 35 cooperate with the bottom of the detachable biosafety liner 2. Through the cooperation of the driving rod 34 and the eccentric wheel 35, the detachable biosafety liner 2 can be pushed upward. One end of the driving rod 34 rotates and extends to one side of the outer protective cylinder 1, and a foot-operated pedal 36 is fixed thereto. A torsion spring 41 is also fixed between the outer protective cylinder 1 and the foot-operated pedal 36. This torsion spring 41 is sleeved on the outer wall of the driving rod 34, and is used to enable the foot-operated pedal 36 to be reset to a vertical state when not subjected to external force.
[0063] Specifically, when emptying the waste collection device, the user can step on the foot-operated pedal 36 to one side. This pedal 36 then rotates the eccentric wheel 35 via the drive rod 34, which in turn pushes the removable biosafety liner 2 upward. When the removable biosafety liner 2 is pushed high enough, its top and the curved, non-slip handle 4 extend above the isolation plate 7. This allows the removable biosafety liner 2 to be easily removed from the outer protective cylinder 1 and cover 5 for dumping and disposal.
[0064] Reference Figure 2 and Figure 9To ensure smooth movement of the removable biosafety liner 2 during its upward movement and reciprocating oscillation, multiple sliding bars 40 are fixed to the inner wall of the outer protective cylinder 1. Accordingly, multiple sliding grooves 39 are provided on the outer wall of the removable biosafety liner 2, which slidably engage with the sliding bars 40. This sliding engagement effectively limits the movement of the removable biosafety liner 2, ensuring smooth and stable movement during its upward movement and oscillation.
[0065] Reference Figure 1 、 Figure 2 and Figure 9 A base plate 37 is fixedly installed on the bottom of one side of the outer protective cylinder 1. 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 user's safe use; on the other hand, the existence of the base plate 37 also effectively lowers the center of gravity of the detachable biosafety liner 2, making the entire outer protective cylinder 1 more stable when placed on the ground and not easy to tip over; the outer protective cylinder 1, the detachable biosafety liner 2 and the biosafety membrane 12 are all provided with biosafety marks.
[0066] In summary, through the design and implementation of the above-described specific embodiment, the waste bag within the waste collection device can automatically cover and cut the biosafety film 12, while also being able to shake and compact the waste, thereby improving the efficiency and safety of quarantine waste treatment. The compaction structure may include a drive device and a transmission device disposed within the cover body 5, with the drive device passing through the transmission device.
[0067] Example 2
[0068] refer to Figure 10 This embodiment is an improvement on Example 1: Multiple negative pressure grooves 43 are provided at the bottom of the outer protective cylinder 1. A piston plate 45 is sealingly and slidably connected to each of these negative pressure grooves 43. A traction rope 46 is fixed to the top of each piston plate 45. A stainless steel fixing rod 42 is fixedly mounted between two adjacent eccentric wheels 35. The top ends of all traction ropes 46 extend into the outer protective cylinder 1 and are fixedly connected to the corresponding fixing rod 42.
[0069] Specifically, when the outer protective cylinder 1 is placed on a smooth ground, the foot-operated pedal 36 and the drive rod 34 can be driven to rotate. When the outer protective cylinder 1 is stably placed, the rotation of the foot-operated pedal 36 is released. At this time, the foot-operated pedal 36 will automatically reset under the action of the torsion spring 41. At the same time, the drive rod 34 will also synchronously drive the eccentric wheel 35 and the fixed rod 42 to rotate. The fixed rod 42 pulls the piston plate 45 upward through the pull rope 46, thereby forming a negative pressure state 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.
[0070] To enhance the seal between the negative pressure tank 43 and the smooth floor, a silicone rubber ring 44 (Shore hardness 40±5, compression set ≤15%) is fixedly installed within the negative pressure tank 43. This rubber ring 44 effectively improves the seal between the negative pressure tank 43 and the floor, further enhancing the stability and reliability of the negative pressure adsorption.
[0071] A method for using an integrated biomaterial waste collection device comprises the following steps:
[0072] S1. Place a waste bag (a PP composite waste bag resistant to high temperatures of 135 degrees) in the detachable biosafety liner 2 first, and the bag 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 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 falling into the waste bag. The sealing door 6 is driven to flip by 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. The screw 18 drives the rotating shaft 10 and the winding roller 2 11 to move through the movable 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 movable 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 is sleeved 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;
[0073] 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 on the top of the waste bag in the detachable biosafety liner 2, and fit the waste bag and the biosafety film 12 together, 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 are fitted together. The hot melt is performed to automatically complete the sealing of the waste bag mouth without manual operation, thereby preventing the staff from being contaminated with bacteria in the waste bag. Then, the pressure rod 25 continues to drive 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, thereby cutting the biosafety film 12 covering the top of the detachable biosafety liner 2, making it convenient for the staff to take the sealed waste bag out of the detachable biosafety liner 2;
[0074] S3. After the cutting blade 31 completes cutting of the biosafety film 12, the screw 18 rotates in the reverse direction, driving the rotating shaft 10 and the reel-2 11 to reset and move. 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 and the rotating shaft 10 are in a locked state. Then, the rotating shaft 10 rotates along with the one-way bearing 15. The reel-2 11 completes the reeling of the biosafety film 12 after cutting, making it easier to pull out the biosafety film 12 that is wound well on the reel-1 9 at a later time.
[0075] S4. In addition, when the movable 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 liner 2, the movable seat 14 drives the movable plate 23 and the curved convex plate 24 to move through the L-shaped bracket 22. The multiple curved convex plates 24 cooperate with the guide column 3 to drive the detachable biosafety liner 2 to shake back and forth up and down, so that the waste in the waste bag in the detachable biosafety liner 2 is shaken inside and filled with waste. Three-quarters of the waste collection device is prevented from overflowing from the waste bag in the detachable biosafety liner 2 and affecting the sealing of the waste bag on the top of the detachable biosafety liner 2 by the biosafety film 12;
[0076] S5. After the detachable biosafety liner 2 is sealed and the rotating shaft 10 is reset, the sealing door 6 is driven by the pressure rod 25 to release the seal on the cover 5. Then, the foot-operated pedal 36 is stepped on to one side. 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 liner 2 upward, so that the top of the detachable biosafety liner 2 and the arc-shaped non-slip lifting handle 4 extend above the isolation plate 7, making it convenient to remove the detachable biosafety liner 2 from the outer protective cylinder 1 and the cover 5. Then, it is convenient for the staff to remove the waste bag encapsulated in the detachable biosafety liner 2;
[0077] S6. In addition, in order to ensure that the outer protective cylinder 1 is placed stably on the ground and will not fall over due to external force, it is necessary to drive the foot operating pedal 36 and the driving rod 34 to rotate when the outer protective cylinder 1 is placed on a smooth ground. When the outer protective cylinder 1 is stably placed, the rotation of the foot operating pedal 36 is released, and the foot operating pedal 36 is reset under the action of the torsion spring 41. The driving rod 34 synchronously drives the eccentric wheel 35 and the fixed rod 42 with the belt 21, and the fixed rod 42 pulls the piston plate 45 upward through the pull rope 46, thereby causing a negative pressure state 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.
[0078] However, as is well known to those skilled in the art, the working principles and wiring methods of the ultraviolet germicidal lamp 32 and the drive motor 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
