Description

Technical Field

[0001] This utility model belongs to the field of medical waste plastic treatment technology, specifically relating to an automated sorting device for medical waste plastic after crushing and cleaning. Background Technology

[0002] Medical waste plastics refer to discarded plastic products generated in the medical field, including syringe shells, infusion bottles (bags), and medical device packaging. Because they may be contaminated with germs and drug residues, improper handling can pose environmental risks and health hazards. Crushing and washing is the core preliminary step for the resource utilization or harmless treatment of medical waste plastics. It aims to remove impurities and reduce hazards through physical means, laying the foundation for subsequent recycling or final disposal.

[0003] The sorting and processing of medical waste plastics after crushing and washing is a core step connecting "crushing and washing" with "recycling." Specifically, it refers to the process of separating different types of plastics, removing residual impurities, and screening for qualified materials from a mixture of crushed and preliminarily washed medical waste plastics using physical, chemical, or intelligent detection methods. Its core objective is to address the problems of "mixed materials, potential pollution, and poor recyclability" in medical waste plastics, providing high-purity, low-risk raw materials for subsequent safe recycling, while simultaneously meeting the compliance and environmental requirements for medical waste treatment.

[0004] Specifically, in the process of sorting medical waste plastic after crushing and cleaning using sorting equipment, air classification is the core step in separating light impurities from plastic particles. However, the matching sorting fans often face the problem of accidental aspiration of medical waste plastic particles due to their operating characteristics. Because there is a negative pressure difference between the airflow channel of the air classification equipment and the fan inlet, if the airflow speed is not properly controlled or the angle of the internal guide plate is not designed reasonably, some light plastic particles can easily deviate from the preset trajectory with the airflow and be sucked into the fan. This medical waste plastic entering the fan can cause multiple problems: particles get stuck in the gap between the fan impeller and the casing, causing the impeller to jam, forcing the sorting equipment to stop; long-term friction can also cause impeller wear, reducing the stability of the fan's air pressure, seriously affecting sorting efficiency and the safety of subsequent recycled raw materials. Utility Model Content

[0005] The purpose of this invention is to provide an automated sorting device for medical waste plastic after crushing and washing. It aims to solve the problem that, during the sorting process of medical waste plastic after crushing and washing, air separation, as the core step in separating light impurities from plastic particles, often suffers from the problem of accidental aspiration of medical waste plastic particles due to the operating conditions of the matching sorting fan. Because there is a negative pressure difference between the airflow channel and the fan inlet of the air separation equipment, if the airflow speed is not properly controlled or the angle of the internal guide plate is not reasonably designed, some light plastic particles can easily deviate from the preset trajectory with the airflow and be sucked into the fan. This medical waste plastic entering the fan causes multiple problems: particles get stuck in the gap between the fan impeller and the casing, causing impeller rotation to stall, forcing the sorting equipment to stop; long-term friction also causes impeller wear, reducing the stability of the fan's air pressure, seriously affecting sorting efficiency and the safety of subsequent recycled raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated sorting device for medical waste plastic after crushing and cleaning, comprising a sorting machine body and a control panel installed on the surface of the sorting machine body, a feeding bin connected to the top of the sorting machine body, an upper sorting plate installed on the inner wall of the sorting machine body, a side plate connected to the surface of the upper sorting plate, a lower sorting plate provided at the bottom of the upper sorting plate, and a discharge plate connected to one end of the lower sorting plate; A sorting fan is installed at the back opening of the sorting machine body. A sorting motor is connected to one side of the sorting fan. A motor bracket is installed on the bottom surface of the sorting motor. A positioning plate is connected to the inner wall of the sorting machine body near the sorting fan. A protective net is connected to the inner side of the positioning plate. Assembly blocks are connected to both the upper and lower ends of the protective net. Locking screws are connected through the surface of the assembly blocks.

[0007] To facilitate safety protection of the sorting fan, in the case of this utility model of an automated sorting device for medical waste plastic after crushing and cleaning, preferably, the protective net is a stainless steel woven structure, the positioning plate has an assembly groove on the side near the assembly block, and the surface size of the protective net is larger than the surface size of the sorting fan.

[0008] To facilitate the assembly of the protective net, as an automated sorting device for medical waste plastic after crushing and cleaning according to this utility model, preferably, the protective net is slidably engaged with the assembly slot on one side of the positioning plate via an assembly block.

[0009] To facilitate stable installation of the protective net, in this utility model of an automated sorting device for medical waste plastic after crushing and cleaning, preferably, the locking screw passes through the assembly block and is threadedly connected to the positioning plate.

[0010] In order to improve the feeding rate, as an automated sorting device for medical waste plastic after crushing and cleaning, preferably, a vibrating motor is installed on the side of the sorting machine body near the upper sorting plate, the output end of the vibrating motor is connected to a shaft, and the other end of the shaft is connected to an eccentric wheel.

[0011] In order to facilitate the sorting and discharge of impurities on the surface of the upper sorting plate, as an automated sorting device for medical waste plastic after crushing and cleaning according to this utility model, preferably, a top block is connected to the inner wall of the upper sorting plate near the eccentric wheel, and the top block is made of steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention involves feeding crushed and cleaned medical waste plastic into the sorting machine via a feeding hopper. The sorting motor then drives a sorting fan to perform air separation on the incoming medical waste plastic. Due to the varying weights of impurities within the medical waste plastic, heavier items fall onto the upper sorting plate, while lighter items are passively blown onto the lower sorting plate for further separation. During this process, the assembly blocks at both ends of the protective net are fitted into the assembly grooves on the surface of the positioning plate. Locking screws are then threaded through the assembly blocks and connected to the positioning plate, ensuring the protective net is stably mounted on the surface of the sorting fan. This prevents medical waste plastic from entering the sorting fan due to pressure differences during the sorting process, thus guaranteeing sorting safety. Attached Figure Description

[0020] Please see Figure 1-5 The present invention provides the following technical solution: an automated sorting device for medical waste plastic after crushing and cleaning, including a sorting body 1 and a control panel 2 installed on the surface of the sorting body 1. A feeding bin 3 is connected to the top of the sorting body 1, an upper sorting plate 4 is installed on the inner wall of the sorting body 1, a side plate 5 is connected to the surface of the upper sorting plate 4, a lower sorting plate 6 is provided at the bottom of the upper sorting plate 4, and a discharge plate 7 is connected to one end of the lower sorting plate 6. A sorting fan 8 is installed at the back opening of the sorting machine body 1. A sorting motor 9 is connected to one side of the sorting fan 8. A motor bracket 91 is installed on the bottom surface of the sorting motor 9. A positioning plate 10 is connected to the inner wall of the sorting machine body 1 near the sorting fan 8. A protective net 11 is connected to the inner side of the positioning plate 10. Assembly blocks 12 are connected to both the upper and lower ends of the protective net 11. Locking screws 14 are connected through the surface of the assembly blocks 12.

[0021] Preferably, the protective net 11 is a stainless steel woven structure, and the positioning plate 10 has an assembly groove 13 on the side near the assembly block 12. The surface size of the protective net 11 is larger than the surface size of the sorting fan 8. In actual use, the protective net 11 facilitates the protection of the sorting fan 8. Preferably, the protective net 11 is slidably engaged with the assembly slot 13 on one side of the positioning plate 10 via the assembly block 12. In actual use, the protective net 11 can be quickly assembled by engaging the assembly block 12 with the assembly slot 13 on one side of the positioning plate 10.

[0022] Preferably, the locking screw 14 passes through the assembly block 12 and is threadedly connected to the positioning plate 10. In actual use, by passing the locking screw 14 through the assembly block 12 and connecting it to the positioning plate 10, the protective net 11 can be installed stably.

[0023] Preferably, a vibration motor 15 is installed on the side of the sorting machine body 1 near the upper sorting plate 4. The output end of the vibration motor 15 is connected to a shaft 16, and the other end of the shaft 16 is connected to an eccentric wheel 17. In actual use, the eccentric wheel 17 facilitates cooperation with the top block 18.

[0024] Preferably, a top block 18 is connected to the inner wall of the upper sorting plate 4 near the eccentric wheel 17. The top block 18 is made of steel. In actual use, by using a steel top block 18, it is convenient to vibrate and discharge the material from the lower sorting plate 6 and the upper sorting plate 4 through the eccentric wheel 17.

[0025] The working principle of this utility model is as follows: First, the crushed and cleaned medical waste plastic enters the sorting machine body 1 through the feeding bin 3. At this time, the sorting motor 9 is controlled to drive the sorting fan 8 to start air sorting of the poured medical waste plastic. At this time, due to the different weights of the impurities inside the medical waste plastic, the heavier objects fall onto the upper sorting plate 4, and the lighter objects are passively blown onto the lower sorting plate 6 for sorting. During the process, the assembly blocks 12 at both ends of the protective net 11 are fitted into the assembly grooves 13 on the surface of the positioning plate 10. Then, the locking screws 14 are passed through the assembly blocks 12 and screwed into the positioning plate 10. The textured connection ensures that the protective net 11 is stably installed on the surface of the sorting blower 8, preventing medical waste plastic from entering the sorting blower 8 due to pressure difference during the sorting process, thus ensuring sorting safety. In addition, when the sorted medical waste plastic or impurities fall onto the surfaces of the lower sorting plate 6 and the upper sorting plate 4, the vibration motor 15 is activated, driving the shaft 16 to rotate, which in turn drives the eccentric wheel 17 to rotate synchronously. This causes the eccentric wheel 17 to reciprocate and impact the top block 18, ensuring rapid discharge of the sorted medical waste plastic or impurities from the surfaces of the lower sorting plate 6 and the upper sorting plate 4.

[0026] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
