Description

Technical Field

[0001] This invention belongs to the field of medical waste treatment technology, specifically an integrated sorting device for infectious medical plastics and metal sharps. Background Technology

[0002] Discarded syringes, as a significant component of infectious medical waste, carry pathogenic microorganisms and pose an extremely high risk of infection transmission. Their sorting and disposal must strictly adhere to medical waste classification standards, ensuring precise separation of needles from syringes and proper classification based on syringe size. Currently, the sorting of discarded syringes largely relies on manual labor or simple equipment. Manual sorting is not only inefficient but also prone to occupational exposure for operators.

[0003] Existing technologies for sorting and disposing of infectious medical plastics and metal sharps, especially waste syringes, have many shortcomings. They cannot achieve automated grading and screening of different syringe models, are prone to mixing and jamming, and are difficult to adapt to the batch disposal needs of multi-specification syringes. They lack a closed negative pressure and scenario-based composite disinfection system, resulting in a high risk of infection source leakage and significant occupational exposure hazards for operators. The equipment structure design is unreasonable, with obvious vibration transmission, easy component wear, poor operational stability, and high maintenance costs. At the same time, it is difficult to achieve precise separation of needles and syringes at the source, which does not meet the requirements for standardized classification and disposal of medical waste, and the disposal efficiency and safety protection capabilities are significantly insufficient. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention provides an integrated sorting device for infectious medical plastics and metal sharps, which solves the problem that existing equipment cannot sort the needles of discarded syringes in medical waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated sorting device for infectious medical plastics and metal sharps, comprising:

[0006] The main body shell is a hollow cylindrical structure. Inside the main body shell, there are three sets of sieving mechanisms for sieving medical syringes arranged from top to bottom. On the inner wall of the main body shell, corresponding to the position of each set of sieving mechanisms, three mounting arms are fixedly connected. The three mounting arms are equidistantly distributed radially along the main body shell. A fixed tray for supporting the sieving mechanism is installed at one end of the three mounting arms facing the axis of the main body shell.

[0007] A composite disinfection mechanism is installed inside the main body shell to achieve simultaneous disinfection during the sieving of waste syringes, thereby reducing the risk of infection.

[0008] The scraper blade adjustment mechanism includes a main spindle, a secondary spindle, a closed-loop stepper motor with a planetary reducer, and a scraper blade assembly. The main spindle has a hollow structure and is rotatably connected to the main housing. The secondary spindle is rotatably connected to the main spindle. The closed-loop stepper motor is installed at the top of the main spindle, and its output end is connected to the secondary spindle for driving the secondary spindle to rotate by a preset angle.

[0009] The bottom of the main body shell is provided with a drive assembly for driving the spindle and scraper to rotate.

[0010] As a further aspect of the present invention: the sorting mechanism includes multiple right-angle brackets fixedly connected to a fixed tray, and a converging annular shell is fixedly connected to the top of the multiple right-angle brackets. A matching converging conical platform is provided inside the converging annular shell. An annular sorting gap is formed between the converging conical platform and the converging annular shell for engaging the syringe finger plate. The converging conical platform and the converging annular shell are fixed by welding multiple metal steel strips.

[0011] As a further aspect of the present invention: the three sets of sieving mechanisms are arranged from top to bottom, and the annular sorting gap in each set of sieving mechanisms gradually decreases, so as to facilitate the grading and sieving of syringes of different models.

[0012] As a further aspect of the present invention: the bottom of the converging annular shell is provided with an annular air bladder, which is used for inflation to clamp and complete the orientation of the syringe barrel.

[0013] As a further aspect of the present invention: a vibration assembly is provided at the bottom of the fixed tray. The vibration assembly includes three mounting brackets fixedly connected to the bottom of the fixed tray. The mounting brackets are rigidly connected to the fixed tray and are equidistantly distributed along the radial direction of the fixed tray. A vibration motor is installed inside the mounting bracket. The eccentric block of the vibration motor faces vertically upward. The vibration motor drives the fixed tray, the converging conical platform, and the converging annular shell to perform low-amplitude horizontal circular translation, providing core power for syringe sorting and orientation.

[0014] As a further aspect of the present invention: the fixed tray and the mounting arm are flexibly connected by a conical rubber vibration damper, which is uniformly and symmetrically distributed along the circumference of the fixed tray; the axial stiffness of the conical rubber vibration damper is greater than its radial stiffness, which supports the fixed tray while not restricting the horizontal circumferential translation of the fixed tray, and isolates the vibration from being transmitted to the main body shell.

[0015] As a further aspect of the present invention: the composite disinfection mechanism includes a HEPA high-efficiency filtration system, a hydrogen peroxide spray disinfection component, and an ultraviolet disinfection lamp. A square mounting port is provided on the main body shell, and the HEPA high-efficiency filtration system is installed in the square mounting port. The hydrogen peroxide spray disinfection component includes several nozzles for spraying hydrogen peroxide solution installed on the inner wall of the main body shell. A combined pipeline is installed on the outer wall of the main body shell for centralized liquid supply to all nozzles. The ultraviolet disinfection lamp is installed on the inner wall of the main body shell.

[0016] As a further aspect of the present invention: the drive assembly includes a drive motor mounted on the bottom of the main body housing, and the output end of the drive motor is connected to the main shaft via a radial magnetic coupler.

[0017] As a further aspect of the present invention: the scraper assembly includes multiple self-aligning bearings fixedly connected to the main shaft body, the self-aligning bearings being used to support the secondary shaft body, a plurality of driving bevel gears being coaxially fixedly connected to the secondary shaft body, driven bevel gears being symmetrically arranged on both sides of the driving bevel gears, the driving bevel gears meshing with the driven bevel gears, the driven bevel gears being rotatably connected to the inner wall of the main shaft body, and a scraper blade being rotatably connected to the outer wall of the main shaft body corresponding to the position of the driven bevel gear.

[0018] As a further aspect of the present invention: the scraping blade is located at the bottom of the converging conical platform and the converging annular shell, and the active bevel gear rotates synchronously with the secondary shaft to realize the angle switching of the scraping blade surface between the vertical avoidance position and the horizontal shearing position.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This equipment achieves automated grading and sieving of different models of medical syringes, and efficient separation of needles and syringe barrels, significantly improving the efficiency and safety of medical waste disposal. The equipment utilizes three sets of top-to-bottom annular sorting mechanisms with progressively decreasing gaps to accommodate syringe barrels of different outer diameters. Combined with a low-amplitude horizontal circular vibration component, it can quickly and precisely position the syringe finger plate. Gravity ensures automatic downward orientation of the needle, and two-point flexible clamping by double-ring airbags completely fixes the syringe barrel's posture. Finally, a scraping blade assembly completes the precise separation of the needle and syringe barrel.

[0021] 2. A dual infection control system has been constructed, featuring a fully enclosed negative pressure system and multi-dimensional composite disinfection, completely eliminating the risk of leakage of infection sources. The equipment adopts a fully enclosed structural design, with sealed inlet and exposed interfaces. Combined with a HEPA high-efficiency filtration system and a matching negative pressure fan operating throughout the entire process, the internal environment of the equipment is always under negative pressure, ensuring that polluted air is filtered efficiently before being discharged. Simultaneously, a scenario-based composite disinfection mechanism is incorporated. The hydrogen peroxide spray component employs a terminal disinfection mode, completing comprehensive disinfection within the enclosed cavity. The ultraviolet disinfection lamps are adapted to the equipment's operating conditions, ensuring disinfection effectiveness while avoiding issues such as ineffective disinfection and rapid component wear during operation. This comprehensively reduces the risk of leakage of infectious aerosols and pathogenic microorganisms.

[0022] 3. Through the nested structure of the hollow main shaft and the built-in secondary shaft, combined with the bevel gear transmission pair driven by the closed-loop stepper motor, the working angle of all layers of scrapers can be adjusted synchronously at one time. During the screening stage, the scraper is adjusted to a vertical avoidance position to prevent syringes from falling and impacting the blade surface, causing jamming or trajectory deviation; during the shearing stage, it quickly switches to a horizontal shearing position to accurately and efficiently shear and separate the needle root. The entire adjustment mechanism has a compact structure and simple control logic. Combined with a high-reduction-ratio planetary reducer and a high-protection-level motor, it ensures the accuracy of angle adjustment and operational stability under harsh medical waste conditions.

[0023] 4. The vibration assembly uses three radially equidistant vibration motors, which can drive the sorting mechanism to perform pure horizontal circular translation, avoiding the generation of torsional torque that affects the sorting effect. At the same time, flexible connection is achieved through conical rubber vibration dampers with axial stiffness greater than radial stiffness, which not only ensures the vibration freedom required for sorting, but also effectively isolates the vibration from being transmitted to the main body of the equipment.

Detailed Implementation

[0031] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0032] Example 1, referring to Figures 1-6 This is the first embodiment of the present invention, which provides an integrated sorting device for infectious medical plastics and metal sharps. It can efficiently separate the needles and syringe bodies of syringes, which are the most difficult to sort in medical waste, so as to facilitate the centralized processing of needles by staff. It includes: a main shell 1, which is a hollow cylindrical structure with a feed port at the top and a circular sharps box at the bottom for holding needles. Inside the main shell 1, there are three sets of sieving mechanisms 2 arranged from top to bottom to sieve medical syringes. The sieving mechanism 2 is based on the principle that different models of syringes have different syringe radii, so as to pre-sieve different models of syringes. On the inner wall of the main shell 1, three mounting arms 3 are fixedly connected to each set of sieving mechanisms 2. The three mounting arms 3 are equidistantly distributed radially along the main shell 1. The three mounting arms 3 are mounted on a fixed tray 4 for supporting the sieving mechanism 2 at one end facing the axis of the main shell 1. The mounting arms 3 can be regarded as the frame inside the main shell 1 and are rigidly connected to the main shell 1.

[0033] The composite disinfection mechanism 5 is located inside the main body shell 1, which enables the simultaneous disinfection of waste syringes during sieving, thereby reducing the risk of infection.

[0034] The scraper blade adjustment mechanism 6 includes a main spindle 7, a secondary spindle 8, a closed-loop stepper motor 9 with a planetary reducer, and a scraper blade assembly 10. The main spindle 7 is a hollow structure and is rotatably connected to the main housing 1. The secondary spindle 8 is rotatably connected to the main spindle 7. The closed-loop stepper motor 9 is installed at the top of the main spindle 7. The output end of the closed-loop stepper motor 9 is connected to the secondary spindle 8 for driving the secondary spindle 8 to rotate a preset angle. The reduction ratio of the planetary reducer is 1:10 to 1:20. The protection level of the closed-loop stepper motor 9 is not lower than IP65.

[0035] The bottom of the main body shell 1 is provided with a drive assembly for driving the spindle body 7 and the scraper blade 103 to rotate.

[0036] It is important to note that the inner wall of the equipment must be in a closed negative pressure environment, so the feed inlet and other exposed interfaces are all sealed.

[0037] Example 2, refer to Figures 2-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a description of the structure and sieving function of the sieving mechanism 2. It includes: the sieving mechanism 2 includes multiple right-angle brackets 21 fixedly connected to the fixed tray 4. A converging annular shell 22 is fixedly connected to the top of the multiple right-angle brackets 21. A converging conical platform 23 is provided inside the converging annular shell 22. An annular sorting gap is formed between the converging conical platform 23 and the converging annular shell 22 for engaging the syringe finger plate. The converging conical platform 23 and the converging annular shell 22 are fixed by welding multiple metal steel strips. The annular sorting gap in each of the three sieving mechanisms 2 gradually decreases from top to bottom to facilitate the grading and sieving of different types of syringes. An annular airbag 24 is provided at the bottom of the converging annular shell 22. The annular airbag 24 is used for inflation and clamping to complete the orientation of the syringe barrel.

[0038] The converging conical platform 23 and the converging annular shell 22 are fixed together by metal steel strips, while the right-angle bracket 21 connects the two to the fixed tray 4. The annular gap formed by the converging conical platform 23 and the converging annular shell 22 is precisely designed to be larger than the outer diameter of the syringe and smaller than the outer diameter of the finger plate. As the annular sorting gap of each layer gradually decreases, after a batch of syringes of different models and sizes enter from the top feed port of the main shell 1, they can be roughly placed in the annular gap of each layer according to their syringe radius. The syringe finger plate is located at the syringe push rod end. When the finger plate is fixed by the converging conical platform 23 and the converging annular shell 22, the overall center of gravity of the syringe and the needle is naturally below the finger plate. Under the action of gravity, it will naturally droop and the needle will uniformly face downward.

[0039] After inflation, the annular airbag 24 can radially and flexibly clamp the upper end of the syringe, which can completely fix the position of the syringe and prevent the syringe from shaking. One side of the syringe is held in place by the annular airbag 24, and the other side is held in place by the bottom of the converging cone 23, thus ensuring overall stability.

[0040] It should be noted that the annular airbag 24 must be made of thickened, puncture-resistant, and chemically corrosion-resistant silicone / butyl rubber, and equipped with a pressure control module to prevent the syringe from bursting or insufficient clamping force. The installation position should be aligned with the syringe body below the wing, rather than clamping the wing itself. The annular airbag 24 is a double-ringed airbag. The upper airbag clamps the upper end of the syringe below the wing, and the lower airbag clamps the middle of the syringe, forming a two-point clamping to completely prevent the syringe from shaking, swaying, or falling off during high-speed rotation, and to ensure the consistency of the needle's orientation angle.

[0041] The rest of the structure is the same as in Example 1.

[0042] Example 3, referring to Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a vibration component 12 and its specific description, which includes: a vibration component 12 is provided at the bottom of a fixed tray 4. The vibration component 12 includes three mounting brackets 121 fixedly connected to the bottom of the fixed tray 4. The mounting brackets 121 are rigidly connected to the fixed tray 4 and are equidistantly distributed radially along the fixed tray 4. A vibration motor 122 is installed inside the mounting bracket 121. The eccentric block of the vibration motor 122 is vertically upward. The vibration motor 122 drives the fixed tray 4, the converging conical platform 23 and the converging annular shell 22 to perform low-amplitude horizontal circular translation, providing core power for syringe sorting and orientation.

[0043] The vibration force generated by the vibration motor 122 can push the syringes in the initial feeding stage to slide orderly into the annular sorting gap, so that the syringe finger plate can be accurately positioned to avoid syringe stacking and jamming. It can also correct the syringe posture and, together with gravity, make the needles uniformly oriented downwards, providing a prerequisite for subsequent accurate needle removal. The horizontal circumferential excitation force generated by each vibration motor 122 will be completely superimposed without generating any torsional torque, ultimately driving the entire fixed tray 4 and the screening mechanism 2 to perform pure horizontal circumferential translation.

[0044] The fixed tray 4 and the mounting arm 3 are flexibly connected by a conical rubber vibration damper 123. The conical rubber vibration damper 123 is evenly and symmetrically distributed along the circumference of the fixed tray 4. The axial stiffness of the conical rubber vibration damper 123 is greater than its radial stiffness. While supporting the fixed tray 4, it does not restrict the horizontal circumferential translation of the fixed tray 4 and isolates the vibration from being transmitted to the main body shell 1. The conical rubber vibration damper 123 can ensure the degree of freedom of vibration and isolate the vibration from being transmitted to the mounting arm 3 and the main body shell 1.

[0045] The rest of the structure is the same as in implementation 2.

[0046] Example 4, refer to Figure 6Unlike the previous embodiment, this embodiment provides a detailed description of the scraper assembly 10, which can realize the angle adjustment of the scraper 103 to meet the requirements of different working conditions. It includes: the scraper assembly 10 includes multiple self-aligning bearings fixedly connected in the main shaft body 7. The self-aligning bearings are used to support the secondary shaft body 8. Several driving bevel gears 101 are coaxially fixedly connected on the secondary shaft body 8. Driven bevel gears 102 are symmetrically arranged on both sides of the driving bevel gears 101. The driving bevel gears 101 and the driven bevel gears 102 mesh. The driven bevel gears 102 are rotatably connected to the inner wall of the main shaft body 7. The scraper 103 is rotatably connected to the outer wall of the main shaft body 7 corresponding to the position of the driven bevel gears 102. The scraper 103 is located at the bottom position of the converging conical platform 23 and the converging annular shell 22. The driving bevel gears 101 rotate synchronously with the secondary shaft body 8 to realize the angle switching of the scraper 103 blade surface between the vertical avoidance position and the horizontal shearing position.

[0047] The secondary shaft 8 is driven by the closed-loop stepper motor 9, which in turn causes the active bevel gear 101, which is fixedly connected to it on the same axis, to rotate. The driven bevel gear 102 that meshes with it rotates accordingly. The angles of each scraper blade 103 can be adjusted synchronously. During sieving, in order to prevent the syringe from falling and hitting the blade surface of the scraper blade 103, which would cause a large change in the movement trajectory of the syringe, the cutting edge of the scraper blade 103 needs to be vertically upward. When the scraper blade 103 needs to rotate to remove the syringe needle, the cutting edge of the scraper blade 103 needs to be adjusted to a horizontal state.

[0048] The rest of the structure is the same as in Example 3.

[0049] Example 5, refer to Figures 1-2 Unlike the previous embodiment, this embodiment provides a description of the composite disinfection mechanism 5 and a specialized design of the drive components to ensure the overall sealing and safety of the device. The composite disinfection mechanism 5 includes a HEPA high-efficiency filtration system 51, a hydrogen peroxide spray disinfection component 52, and an ultraviolet disinfection lamp 53. A square mounting port is provided on the main body shell 1, and the HEPA high-efficiency filtration system 51 is installed inside the square mounting port. The hydrogen peroxide spray disinfection component 52 includes several nozzles 521 installed on the inner wall of the main body shell 1 for spraying hydrogen peroxide solution. A combined pipeline 522 is installed on the outer wall of the main body shell 1 for centralized liquid supply to all nozzles 521. The ultraviolet disinfection lamp 53 is installed on the inner wall of the main body shell 1.

[0050] The HEPA high-efficiency filtration system 51 is used in conjunction with a negative pressure fan, which is kept running throughout the entire process. This ensures that all contaminated air inside the equipment is filtered through the HEPA high-efficiency filter before being discharged, thus preventing the leakage of infection sources at the source. The nozzle 521 in the hydrogen peroxide spray disinfection component 52 is activated at the end. After processing materials for each shift or completing a fixed batch of medical waste, the feeding is stopped first, all materials inside the equipment are processed, the inlet and outlet gates are closed, and a sealed cavity is formed before the nozzle 521 is activated. The ultraviolet disinfection lamp 53 is activated and deactivated along with the HEPA high-efficiency filtration system 51, avoiding ineffective activation and extending the lamp life. During operation, syringes, splashed liquids, and dust can completely block ultraviolet rays, resulting in almost zero disinfection effect. Furthermore, humid and corrosive environments can drastically shorten the life of ultraviolet lamps and may also cause lamp breakage and the risk of glass shards mixing into medical waste.

[0051] The drive assembly includes a drive motor 111 mounted on the bottom of the main housing 1. The output end of the drive motor 111 is connected to the main shaft 7 via a radial magnetic coupler. The use of the radial magnetic coupler can avoid direct connection between the output shaft of the drive motor 111 and the main housing 1, thereby ensuring the overall sealing of the main housing 1, reducing the risk of pressure loss and leakage, and in situations where the torque requirement is not high, the use of the radial magnetic coupler can also avoid equipment damage caused by motor overload.

[0052] The remaining structure is the same as in Example 4.

[0053] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
