Description

Technical Field

[0001] This utility model belongs to the field of medical waste plastic treatment technology, specifically relating to a continuous crushing and cleaning automated production line for medical waste plastic. Background Technology

[0002] The continuous crushing and washing automated production line for medical waste plastics is a resource recycling system designed for uncontaminated medical plastic waste (such as infusion bottles, infusion bags, drip bottles, etc.). The collected medical waste plastics undergo preliminary screening to remove obvious impurities, and are then fed into the production line via conveyor belt or manually. The crushed material enters the friction washing machine, where paper labels and adhesives are washed out by a high-speed rotating friction disc. The label pulp is collected through a bottom pipe, and the washed material enters the rinsing tank. The water flow separates the submerged rubber stoppers from the floating plastic sheets, and the floating plastic is scooped out by the discharge roller.

[0003] The automated continuous crushing and washing production line for medical waste plastics, in practical application, has encountered a series of rather thorny problems during operation. Medical waste plastics often contain residual medication, and in the existing production process, these untreated waste plastics are directly sent to the washing tank for cleaning. As a result, the medication flows into the tank, causing serious pollution to the water and ultimately directly affecting the washing quality of the waste plastic particles. Utility Model Content

[0004] The purpose of this invention is to provide a continuous crushing and washing automated production line for medical waste plastics, which aims to solve the problem that medical waste plastics usually contain residual medicine liquid. In the existing production process, these untreated waste plastics are directly sent to the washing tank for washing. As a result, the medicine liquid flows into the tank, causing serious pollution to the water in the washing tank and ultimately affecting the washing quality of the waste plastic particles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous crushing and cleaning automated production line for medical waste plastic, comprising a crushing component and a cleaning component installed on the side surface of the crushing component. The crushing component includes a crushing shell, a feeding hopper, and a crushing roller. The top of the crushing shell is connected to the feeding hopper, and the feeding roller is installed inside the feeding hopper. The crushing component is equipped with a rinsing component for cleaning the crushed waste plastic, and a vibration component for shaking off moisture from the crushed waste plastic. A waste liquid discharge component is installed on the side surface of the crushing shell.

[0006] As a preferred embodiment of the automated continuous crushing and washing production line for medical waste plastics of this utility model, the vibration assembly includes a filter plate, a first connecting plate, a second connecting plate, a guide rod, a spring strip, a limiting block, a drive motor, and an eccentric wheel. The filter plate is disposed on the inner wall of the crushing shell and extends to the outside. The inner wall of the filter plate is connected to the first connecting plate, and the inner wall of the crushing shell is connected to the second connecting plate. The guide rod, which is connected to the upper surface of the first connecting plate, passes through the interior of the second connecting plate. The top of the guide rod is connected to the limiting block, and the upper surface of the first connecting plate is connected to the spring strip, which is connected to the second connecting plate.

[0007] As a preferred embodiment of the automated production line for continuous crushing and washing of medical waste plastics of this utility model, a drive motor is installed on the side surface of the crushing shell, and the output end of the drive motor is connected to an eccentric wheel that abuts against the bottom side of the filter plate.

[0008] As a preferred embodiment of the automated production line for continuous crushing and cleaning of medical waste plastics of this utility model, the rinsing assembly includes a rinsing pipe, a water inlet pipe, a solenoid valve, a connecting pipe, and a nozzle. The rinsing pipe is connected to the inner wall of the crushing shell, and a nozzle is installed on one side of the rinsing pipe, with the nozzle aligned with the surface of the filter plate.

[0009] As a preferred embodiment of the automated production line for continuous crushing and cleaning of medical waste plastics of this utility model, the end of the rinsing pipe is connected to a water inlet pipe extending to the outside of the crushing shell, a solenoid valve is installed in the middle of the water inlet pipe, and the end of the water inlet pipe is connected to a connecting pipe for docking with a hose.

[0010] As a preferred embodiment of the automated production line for continuous crushing and cleaning of medical waste plastics of this utility model, the waste liquid discharge assembly includes a waste liquid discharge pipe and a shut-off valve. The waste liquid discharge pipe is connected to the storage tank of the crushing shell on the side surface of the crushing shell, and a shut-off valve is installed in the middle of the waste liquid discharge pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, after the solenoid valve is opened, water can enter the interior of the flushing pipe through the connecting pipe and the inlet pipe. Then, the water inside the flushing pipe can be sprayed out through the nozzle, thereby washing away the residual medicine on the surface of the waste plastic particles. This prevents the residual medicine from falling into the water of the cleaning component along with the waste plastic particles, thus affecting the subsequent cleaning of the waste plastic particles. This invention uses the vibration of the filter plate to shake off the water adhering to the surface of the waste plastic particles and place it inside the crushing shell, thereby preventing the waste from entering the water in the cleaning component.

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.

[0015] Please see Figures 1-5 The present invention provides the following technical solution: a continuous crushing and cleaning automated production line for medical waste plastic, including a crushing component 1 and a cleaning component 2 installed on the side surface of the crushing component 1. The crushing component 1 includes a crushing shell 101, a feeding hopper 102 and a crushing roller 103. The top of the crushing shell 101 is connected to the feeding hopper 102.

A vibration component 3 for shaking off the moisture in the crushed waste plastic is installed inside the crushing component 1. A waste liquid discharge component 5 is installed on the side surface of the crushing shell 101.

[0016] First, waste plastic such as medical infusion bottles is put into the inside of the feed hopper 102. Then, the waste plastic falls into the crushing shell 101 and is crushed by the crushing roller 103. Then, the crushed waste plastic particles enter the inside of the cleaning component 2 for cleaning.

[0017] Preferably, the vibration assembly 3 includes a filter plate 301, a first connecting plate 302, a second connecting plate 303, a guide rod 304, a spring strip 305, a limiting block 306, a drive motor 307, and an eccentric wheel 308. The filter plate 301 is disposed on the inner wall of the crushing shell 101 and extends to the outside. The inner wall of the filter plate 301 is connected to the first connecting plate 302, and the inner wall of the crushing shell 101 is connected to the second connecting plate 303. The guide rod 304, which is connected to the upper surface of the first connecting plate 302, passes through the interior of the second connecting plate 303. The top of the guide rod 304 is connected to the limiting block 306. The upper surface of the first connecting plate 302 is connected to the spring strip 305, which is connected to the second connecting plate 303.

[0018] Preferably, a drive motor 307 is installed on the side surface of the crushing shell 101, and the output end of the drive motor 307 is connected to an eccentric wheel 308 that abuts against the bottom side of the filter plate 301.

[0019] In practical use, when the drive motor 307 is running, it can drive the eccentric wheel 308 to rotate, and when the eccentric wheel 308 rotates, it can drive the filter plate 301 to vibrate.

[0020] Preferably, the rinsing assembly 4 includes a rinsing pipe 401, an inlet pipe 402, a solenoid valve 403, a connecting pipe 404, and a nozzle 405. The rinsing pipe 401 is connected to the inner wall of the crushing housing 101, and the nozzle 405 is installed on one side of the rinsing pipe 401 and is aligned with the surface of the filter plate 301.

[0021] In practical use, after the water enters the interior of the flushing pipe 401, it can pass through the nozzle 405. The water flow sprayed from the nozzle 405 can flush the waste plastic particles on the surface of the filter plate 301, thereby washing away the residue remaining on the surface of the waste plastic.

[0022] Preferably, the end of the flushing pipe 401 is connected to a water inlet pipe 402 extending to the outside of the crushing shell 101, a solenoid valve 403 is installed in the middle of the water inlet pipe 402, and the end of the water inlet pipe 402 is connected to a connecting pipe 404 for docking with a hose.

[0023] In practical use, the hose can be connected to the connecting pipe 404, and then the flow of water can be controlled by the solenoid valve 403.

[0024] Preferably, the waste liquid discharge assembly 5 includes a waste liquid discharge pipe 501 and a shut-off valve 502. The waste liquid discharge pipe 501, which is connected to the liquid storage tank of the crushing shell 101, is connected to the side surface of the crushing shell 101. The shut-off valve 502 is installed in the middle of the waste liquid discharge pipe 501.

[0025] In practical use, when the shut-off valve 502 is opened, the waste liquid inside the cavity of the crushed housing 101 can be discharged through the waste liquid discharge pipe 501.

[0026] Working principle: When using this device, the waste plastic particles crushed by the crushing roller 103 can fall onto the surface of the filter plate 301. At this time, the drive motor 307 can be run. When the drive motor 307 runs, it can drive the eccentric wheel 308 to rotate. The spring strip 305 can make the eccentric wheel 308 drive the filter plate 301 to vibrate when it rotates. When the filter plate 301 vibrates, it can drive the waste plastic to slide downward. At this time, the solenoid valve 403 is turned on. After the solenoid valve 403 is turned on, the water can enter the flushing pipe 401 through the connecting pipe 404 and the inlet pipe 402. Then the water inside the flushing pipe 401 can be sprayed out through the nozzle 405. The residual liquid on the surface of the waste plastic particles can be washed off by the sprayed water. After rinsing, the waste liquid can fall into the chamber of the crushing shell 101 through the filter plate 301. At the same time, the vibration of the filter plate 301 can shake off the water adhering to the surface of the waste plastic particles and fall into the chamber of the crushing shell 101. When the waste plastic particles are shaken off at the end of the filter plate 301, they can fall into the cleaning component 2 and be cleaned. When the waste liquid inside the crushing shell 101 is full, the shut-off valve 502 can be opened. After the shut-off valve 502 is opened, the waste liquid can be discharged through the waste liquid discharge pipe 501.

[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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.
