Description

A waste plastic recycling equipment with crushing and cleaning functions Technical Field

[0001] The present invention relates to the technical field of waste plastic processing, in particular to waste plastic recycling equipment with crushing and cleaning functions. Background Art

[0002] Recycled granules are the abbreviation of recycled plastic granules. Recycled plastic granules belong to the category of plastic granules. Recycled plastics are plastics produced by recycling used new materials or waste plastics through a screw machine, and then cut into granular plastic granules by a granulator. Plastic waste is everywhere in life, and it can be recycled and reused to make granules and used in all aspects of life. However, the application areas are different. For example, convenient bags made of recycled granules cannot be used for food packaging, and some granules processed from PVC may contain toxins themselves, so their application range will be limited. Generally speaking, the first and second grade materials can be used for film blowing, wire drawing, etc., while the third grade materials can generally only be used for injection molding.

[0003] In the existing recycling and regeneration process of waste plastic particles, due to the presence of impurities deposited in grooves, cracks and holes on the surface of the waste plastic, the powdered impurities on the surface of the semi-finished plastic particles are easily affected by the rolling, vibration and impact of the plastic during the pouring and cleaning process, and are easily scattered and flown away, seriously affecting the subsequent feeding process and causing pollution to the surrounding working environment. After the existing waste plastic particles are initially shredded, a large amount of impurities still remain, seriously affecting the subsequent recycling and use. In addition, during the cleaning process of the semi-finished plastic particles, impurities are easily left on the surface of the plastic particles at the bottom.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0014] A working method of a waste plastic recycling and regeneration device with crushing and cleaning functions comprises the following steps:

[0015] Step 1: Open the hopper cover and pour the semi-finished plastic granules into the inner cylinder through the hopper. The driving motor drives the driven gear ring to rotate through the coupling and the active gear ring. The driven gear ring drives the inner cylinder to rotate along the inside of the outer cylinder. Clean water is guided into the inner cylinder through the water inlet. The servo motor drives the stirring paddle through the coupling and the hollow shaft to stir and clean the semi-finished plastic granules. The micromotor drives the cutter through the coupling and the rotating shaft to crush the stirred semi-finished plastic granules to obtain finished plastic granules.

[0016] Step 2: During the water injection process, the water injection pipe distributes the water flow to several water spray rings through the water distribution pipe. Conical teeth are provided at both ends of the transmission rod and engage with the hollow shaft and the rotating retaining ring respectively. The rotating retaining ring rotates along the bottom of the water spray ring. The water sprayed by the water spray ring is blocked and dispersed by the rotating retaining ring and then drips into the inner cylinder.

[0017] Step 3: During the stirring, cleaning, and mixed crushing process of the semi-finished plastic particles in the inner cylinder, the hollow shaft drives the stirring paddle to rotate at a constant speed to stir and clean the semi-finished plastic particles in the inner cylinder. The second micromotor drives the rotating shaft and the cutter to rotate via the coupling to crush the semi-finished plastic particles passing through. The hollow shaft is engaged with the transmission gear via the sleeve gear. The transmission gear engagement drives the rectangular frame to rotate in the opposite direction along the inside of the stirring paddle. The external air pump guides the air flow through the hollow shaft along the air hole into the slip ring. The slip ring sprays the air flow to the bottom of the inner cylinder through the aeration pipe to obtain the finished plastic particles.

[0018] Step 4: During the mixing, cleaning and crushing process of the semi-finished plastic particles, the micromotor 1 drives the kit to rotate through the coupling, and the kit drives the ring frame to rotate synchronously until the filter slot part on the ring frame is aligned with the leakage hole 1, and the bottom of the inner cylinder slides along the guide rail and rotates in the outer cylinder. The leakage hole 1 on the leakage plate and the leakage hole 2 on the fixed plate are intermittently connected up and down, and the water injection pipe continuously injects water into the inner cylinder. The sewage containing impurities at the bottom of the inner cylinder enters the cone along the leakage hole 1. The rotating motor drives the guide plate to deflect through the coupling and the adjusting shaft, and diverts the impurity-containing water flow that falls into the recess along the guide slot to one side of the Y-shaped outlet, while the semi-finished plastic particles are intercepted by the filter slot. The micromotor 1 drives the ring frame to rotate further through the coupling. The ring frame rotates until the empty slot is aligned with the leakage hole 1, and the water flow in the inner cylinder and the finished plastic particles enter the cone along the leakage hole 1, the empty slot and the leakage hole 2. The rotating motor drives the guide plate to deflect in the opposite direction, and the finished plastic particles and water flow are concentrated and discharged along the other side of the Y-shaped outlet.

[0019] Beneficial effects of the present invention:

[0020] The present invention uses multiple groups of water spray rings and a servo motor structure in conjunction to cause the injected cleaning water to explode and drip, forming a continuously falling water curtain at the top of the inner cylinder. This helps to continuously intercept and purify some of the powdered and scattered impurities during the injection of semi-finished plastic particles, preventing them from overflowing along the feed port and polluting the surrounding working environment.

[0021] The inner cylinder and the cone structure are used in conjunction with each other, and the inner cylinder rotates at a uniform speed inside the outer cylinder, which causes the leakage hole 1 and the leakage hole 2 to intermittently connect, making it easier for the cleaning water and plastic particles in the inner cylinder to be discharged from the bottom layer by leakage. The ring frame is rotated and fine-tuned between the leakage plate and the pressure cover to further control the leakage discharge of the leakage hole 1 and the leakage hole 2, and implement sealed isolation, mesh layer screening and centralized discharge.

[0022] By using the stirring paddle and the rectangular frame structure in conjunction with each other, the stirring structure is reversed on the outside and inside of the inner cylinder cavity. The cutter is driven by micromotor 2 to rotate between the stirring paddles to further crush the semi-finished plastic particles passing through. The aeration pipe is used to aerate the cleaning water in the inner cylinder to promote the stirring and tumbling of the semi-finished plastic particles in the cleaning water.
