Description

Technical Field

[0001] This utility model belongs to the field of medical waste plastic recycling and reuse technology, specifically relating to environmentally friendly granulation equipment for medical waste plastic recycling and reuse. Background Technology

[0002] Environmentally friendly granulation equipment for recycling and reusing medical waste plastics is a specialized device for recycling, processing, and reprocessing waste plastics generated in the medical field (such as infusion bottles, syringe shells, and packaging films) into reusable plastic granules. Its core design balances the safe handling of medical waste (such as disinfection and impurity removal) with the environmental friendliness of plastic recycling (such as low energy consumption and low emissions), while also ensuring the quality stability of the recycled granules.

[0003] Specifically, when using granulation equipment to crush waste plastic products, the materials, mostly polyethylene, polypropylene, and other polymers, exhibit high toughness and impact resistance. Under the action of high-speed rotating crushing blades, they are prone to irregular fracture due to uneven stress. The fragments fly outwards at high initial velocity, potentially impacting the inner walls of the equipment, causing wear and shortening its lifespan. Furthermore, the increased temperature of the flying debris due to friction poses a risk of skin burns or clothing ignition if operators are not properly protected. Simultaneously, the flying fine debris disperses into the work environment, causing airborne dust pollution, affecting visibility and posing a potential threat to the respiratory health of workers exposed for extended periods. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly granulation device for recycling medical waste plastics. It addresses the problem that waste plastics are mostly made of high-molecular materials such as polyethylene and polypropylene, which are characterized by high toughness and impact resistance. Under the action of high-speed rotating crushing blades, they are prone to irregular fracture due to uneven stress. The fragments fly outwards at high initial velocity, potentially impacting the inner walls of the equipment, causing wear and tear on components and shortening its lifespan. Furthermore, the increased temperature of the flying debris due to friction poses a risk of skin burns or clothing ignition if operators are not properly protected. Simultaneously, the flying fine debris disperses into the working environment, causing airborne dust pollution, affecting visibility and posing a potential threat to the respiratory health of workers exposed for extended periods.

An isolation plate is connected to the surface opening of the feeding hopper, and a handle is connected to the top of the isolation plate. A fixing block is connected to the surface of the feeding hopper near the isolation plate. An adjusting block is connected to the opening at one end of the fixing block. A linkage plate is connected to one end of the adjusting block. A linkage spring is connected to one side of the linkage plate, and a positioning block is connected to the other side of the linkage plate.

[0006] To facilitate the vertical adjustment of the isolation plate, as an environmentally friendly granulation device for recycling medical waste plastics according to this utility model, preferably, the surface dimensions of the isolation plate are adapted to the inner wall dimensions of the feeding hopper opening, and the isolation plate and the opening on the surface of the feeding hopper form a sliding connection structure.

[0007] To facilitate automatic locking of the positioning block, in the case of the environmentally friendly granulation equipment for recycling medical waste plastics of this utility model, preferably, one end of the linkage spring relative to the linkage plate is connected to the inner wall of the fixed block, and the linkage spring and the linkage plate form an elastic telescopic structure.

[0008] To facilitate the movement of the positioning block, as an environmentally friendly granulation device for recycling and reusing medical waste plastics according to this utility model, preferably, the positioning block passes through and extends to the outside of the fixed block.

[0009] To facilitate locking and fixing the isolation plate, as an environmentally friendly granulation device for recycling and reusing medical waste plastics according to this utility model, preferably, a positioning groove is provided on the side of the isolation plate near the positioning block, and the positioning block and the positioning groove on one side of the isolation plate form an interlocking structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention involves feeding waste plastic products into a feeding hopper, where they are crushed by a crushing roller inside the crushing chamber. Simultaneously, an adjusting block on one side of the fixed block is pulled, causing the partition plate to slide through the opening on the surface of the feeding hopper, thus closing the opening. Furthermore, the elastic extension and contraction structure of the linkage spring facilitates the engagement and connection of the positioning block with the positioning groove on the surface of the partition plate, allowing for quick and easy locking of the partition plate. This design prevents the splashing of waste plastic fragments during granulation, avoiding equipment damage and ensuring a safe processing environment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 The present invention provides the following technical solution: an environmentally friendly granulation equipment for recycling and reusing medical waste plastic, including a feeding bin 1 and a crushing box 2 installed at the bottom of the feeding bin 1. The bottom of the crushing box 2 is connected to a conveying box 3, and the bottom of the conveying box 3 is connected to a spiral granulation cylinder 4. The top and bottom surfaces of the spiral granulation cylinder 4 are connected to a discharge port 5. A crushing motor 21 is installed on the side of the crushing box 2, and the output end of the crushing motor 21 is connected to a crushing roller 22 via a belt. An isolation plate 6 is connected to the surface opening of the feeding bin 1. A handle 7 is connected to the top of the isolation plate 6. A fixing block 8 is connected to the surface of the feeding bin 1 near the isolation plate 6. An adjusting block 9 is connected to the opening at one end of the fixing block 8. A linkage plate 10 is connected to one end of the adjusting block 9. A linkage spring 11 is connected to one side of the linkage plate 10. A positioning block 12 is connected to the other side of the linkage plate 10.

[0017] Preferably, the surface dimensions of the isolation plate 6 are adapted to the inner wall dimensions of the opening of the feeding bin 1, and the isolation plate 6 and the opening on the surface of the feeding bin 1 form a sliding connection structure. In specific use, after the medical waste plastic is initially sorted by hand to remove the severely polluted or non-renewable categories, it is sent to the pretreatment unit. Through cleaning and disinfection, pollutants and bacteria are removed, and metal and paper debris are separated. The cleaned waste plastic fragments enter the melt extrusion unit, where they are melted and plasticized at high temperature. After being filtered through a filter screen, they form a continuous plastic melt. The melt is extruded into strips through a die head, hardened by a cooling system, and then cut into uniform particles by a pelletizer. The particles are collected after screening. The waste gas and wastewater generated in the process are treated by the environmental protection unit and then discharged or reused. Preferably, one end of the linkage spring 11 relative to the linkage plate 10 is connected to the inner wall of the fixing block 8, and the linkage spring 11 and the linkage plate 10 form an elastic telescopic structure. In actual use, by utilizing the elastic telescopic structure between the linkage spring 11 and the linkage plate 10, it is convenient to position and move the positioning block 12.

[0018] Preferably, the positioning block 12 passes through and extends to the outside of the fixing block 8.

[0019] Preferably, a positioning groove 13 is provided on the side of the isolation plate 6 near the positioning block 12, and the positioning block 12 and the positioning groove 13 on one side of the isolation plate 6 form a fitting structure. In actual use, the positioning block 12 is inserted and connected with the positioning groove 13 on one side of the isolation plate 6 after passing through the fixing block 8. This makes it easy to install the isolation plate 6 stably, thereby avoiding the phenomenon of splashing during processing.

[0020] The working principle of this utility model is as follows: First, after the waste plastic products are fed into the feeding hopper 1, the crushing roller 22 inside the crushing box 2 crushes the waste plastic products. At the same time, the adjusting block 9 on one side of the fixing block 8 is pulled, which slides the isolation plate 6 on the opening of the feeding hopper 1, thus closing the opening of the isolation plate 6 in the feeding hopper 1. Simultaneously, due to the elastic extension and contraction structure of the linkage spring 11, the positioning block 12 is moved through the fixing block 8, which facilitates the engagement and docking of the positioning block 12 with the positioning groove 13 on the surface of the isolation plate 6, thereby facilitating the quick locking and fixing of the isolation plate 6. When the waste plastic products are granulated, the phenomenon of waste plastic product fragments splashing is avoided, preventing equipment damage and ensuring the safety of the processing environment.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
