Description

Technical Field

[0001] The invention relates to the technical field of medical waste crushing treatment, in particular to a circulating crushing device for pre-treatment of medical waste. Background Art

[0002] Medical waste, as an important challenge in the field of public health, mainly comes from medical institutions, medical laboratories, biomedical research facilities and other decentralized sources. It is worth noting that although hospitals are the main source of medical waste, their actual generation only accounts for a small proportion of the total amount of medical waste.

[0003] Improper management and disposal of medical waste may lead to serious risks of secondary disease transmission. This risk not only threatens those who are in direct contact, such as garbage collectors, waste treatment workers and medical staff, but may also affect the health and safety of the patient group and even the entire community. According to internationally accepted classification standards, medical waste can be systematically divided into five categories: infectious waste, damaging waste, pathological waste, pharmaceutical waste and chemical waste. Among them, damaging waste specifically refers to discarded medical sharps with the risk of puncture or cut, including metal products (such as injection needles, surgical suture needles, dissecting knives, etc.), glass products (such as slides, cover glasses, etc.) and sharps of other materials.

[0004] The environmental hazards of medical waste are mainly reflected in its multiple pollution effects on soil, water and atmospheric systems. Therefore, it is crucial to establish a centralized disposal system to effectively prevent its loss, leakage and spread. The current medical waste treatment process usually includes classified collection, sterilization and disinfection, physical treatment and clean disposal. Given the diversity of medical waste, there are significant differences in the treatment methods of different types of waste. Taking medical sharps as an example, professional crushing and destruction must be carried out.

[0005] Deformation treatment is to make sharp objects lose their original shape and break them up by mechanical means, thereby reducing the risk of treatment and optimizing space utilization. At present, extrusion crushing technology is widely used, and this process must be completed on special equipment. The particle size of medical waste treated by professional crushing equipment is usually controlled below 5cm.

[0006] However, the existing medical waste destruction equipment generally has the problem of insufficient specialization, which is mainly manifested in the following aspects: 1. The equipment has poor adaptability to different types of medical waste, and it is difficult to ensure a stable destruction treatment effect; 2. The adjustment performance of the crushing mechanism is limited, and it is easy to cause blockage when processing special forms of medical waste; 3. Some medical waste needs to be crushed in multiple cycles to reach the predetermined particle size standard, but the material transfer efficiency of existing equipment during the cyclic crushing process is low.

[0007] These problems highlight the urgent need for improvement in the specialization, intelligence and adaptability of medical waste treatment equipment.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0031] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes efficient and safe medical waste treatment through the synergistic effect of a series of innovative components. As the primary link of the system, the pretreatment shearing component has a unique design that combines the dual functions of crushing pretreatment and pathogen inactivation. The component adopts a vertical pretreatment cylinder structure, with a feed hopper on the top, a rotating shearing knife in the middle, and an array of ultraviolet sterilization lamps around the inner wall of the lower part. After the medical waste enters through the feed hopper, it undergoes shear crushing and ultraviolet irradiation disinfection in sequence under the action of gravity, and is finally discharged from the bottom. This design not only effectively kills pathogens and blocks the biological infection chain, but also significantly reduces the subsequent processing load through pre-crushing.

[0032] As the logistics center of the system, the conveyor assembly realizes the seamless connection of each processing unit. The assembly adopts a double-ply plate support structure, with adjustable conveyor rollers at both ends, and realizes material transfer through the conveyor belt. Its innovation lies in the precise displacement adjustment system, which consists of a sliding drive motor and a drive threaded rod, which can accurately control the spatial position of the conveyor belt. This design enables the conveyor belt to flexibly adapt to the needs of different processes. For example, when transferring materials after pretreatment, the conveyor belt can be accurately positioned above the transfer loading box; in the final discharge stage, it can be accurately moved to the bottom of the crushing box for reverse conveying, which fully reflects the intelligent characteristics of the system.

[0033] The circulating feeding component is a key device to ensure multiple crushing effects. The component adopts a rotating double-station design, consisting of a feeding turntable and two flippable transfer feeding boxes. Through the coordinated control of the steering drive motor and the rotation drive motor, the continuous lifting and precise delivery of medical waste are achieved. Its uniqueness lies in the use of a dynamic balancing system to ensure that the transfer feeding box always maintains the best receiving posture during the rotation process, greatly improving the operating efficiency and reliability of the system.

[0034] As the core processing unit, the rolling crushing component adopts an innovative three-roller progressive crushing solution. The three crushing rollers are distributed symmetrically, and the roller spacing is continuously adjustable through a precision adjustment mechanism. The component is equipped with an intelligent adjustment system consisting of an electric telescopic cylinder, a mobile motor seat and a rolling drive motor, which can optimize the crushing parameters in real time according to the material characteristics. Through the multi-stage progressive crushing process, the refined treatment of medical waste is achieved, fully meeting the treatment needs of different types of waste.

[0035] The innovation of this invention lies in the organic integration of pretreatment, transportation, circulating feeding and rolling crushing processes to form a complete closed-loop treatment system. The precise coordination between the components is achieved through intelligent control, which not only improves the treatment efficiency, but also significantly improves the safety and adaptability of the system. This integrated design provides a reliable technical solution for the harmless treatment of medical waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Two symmetrical conveying rollers 31 are respectively disposed at the two ends of the two conveying clamping plates 30 , and a conveying belt 32 is sleeved between the two conveying rollers 31 .

[0057] A conveying drive motor 37 is fixedly connected to the longitudinal outer wall of each conveying clamp plate 30 near the end. The end of the output shaft of the conveying drive motor 37 passes through the conveying clamp plate 30 and is fixedly connected to the side end surface of one of the conveying rollers 31 .

[0059] Two symmetrical sliding drive motors 34 are fixedly connected to the upper surface of the horizontal part of the first support plate 2, and a horizontal driving threaded rod 35 is fixedly connected to the end of the output shaft of each sliding drive motor 34. A vertical sliding support plate 36 is fixedly connected to the side edge of the first support plate 2 near the end, and the upper end of the sliding support plate 36 is arranged close to the lower end of the conveying splint 30.

[0060] The two driving threaded rods 35 pass through and are threadedly connected to the U-shaped driving plate 33 , respectively. The end of each driving threaded rod 35 is rotatably supported on the lateral side wall of the sliding support plate 36 .

[0061] When the present invention is used: First, the shearing drive motor 25 is started, and the shearing drive motor 25 drives the shearing blade 26 to rotate. The medical waste to be processed is put into the upper end of the feed hopper 23, and the medical waste slides down into the pretreatment cylinder 21. After the shearing blade 26 rotates and is shredded and sterilized by the ultraviolet sterilization lamp 27, the medical waste falls onto the conveyor belt 32.

[0062] Next, the sliding drive motor 34 is started, and the sliding drive motor 34 drives the driving threaded rod 35 to rotate, driving the U-shaped driving plate 33 to move horizontally. Thus, the two conveying clamping plates 30 are driven to slide horizontally along the sliding communication opening 29 to adjust the position of the end of the conveyor belt 32 until it moves to the upper side of the transfer loading box 18.

[0063] Then, the conveying drive motor 37 is started, and the conveying drive motor 37 drives the conveying roller 31 to drive, and then drives the conveying belt 32 to rotate cyclically. The pre-treated medical waste is conveyed to the transfer loading box 18.

[0064] After the medical waste is transported, the sliding drive motor 34 is controlled to rotate in the opposite direction to move the conveyor belt 32 away from above the transfer loading box 18 .

[0065] The steering drive motor 14 is started, and the steering drive motor 14 drives the feeding turntable 13 to rotate 180 degrees, and the transfer feeding box 18 located below the crushing box 4 is moved to the top of the crushing box 4. During the rotation of the feeding turntable 13, the rotation drive motor 17 is started, and the rotation drive motor 17 drives the transfer feeding box 18 to rotate, so that the transfer feeding box 18 is kept in an upward opening state in real time.

[0066] The rolling drive motor 12 is started, and the rolling drive motor 12 drives the crushing roller 6 to rotate. At the same time, the electric control telescopic cylinder 10 is controlled to extend and retract, and the distance between adjacent crushing rollers 6 is adjusted.

[0067] The swing drive module 20 is started to control the stop baffle 19 to swing open, so that the medical waste falls into the crushing box 4. After being guided by the guide frame 5, the medical waste enters between the crushing rollers 6 for extrusion and crushing.

[0068] After the first crushing is completed, the medical waste slides down along the guide frame 5 into the crushing box 4 below. The above rotation and feeding process is repeated, and the distance between adjacent crushing rollers 6 is reduced by controlling the electric control telescopic cylinder 10 to shorten again, so as to perform a more detailed crushing process until the crushing requirements of the medical waste are met.

[0069] During the last rotation and feeding process, the conveying clamping plate 30 is driven to move horizontally again until the conveying belt 32 moves to the bottom of the crushing box 4. The conveying drive motor 37 is controlled to reverse so that the crushed medical waste falls directly onto the conveying belt 32 and is transported horizontally.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
