Description

A recycled plastic particle cleaning device for plastic product production

Technical Field

The invention relates to the technical field of plastic processing, in particular to a recycled plastic particle cleaning device for producing plastic products.

Background technique

Plastic waste is everywhere in our lives, and it can be recycled and reused to make granules, which can be used in various aspects of life, but the application fields are different. For example, convenient bags made of recycled granules cannot be used for food packaging, and some granules processed with 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. 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.

In the prior art, plastic recycling and granulation operations require the recycling of waste plastics to be classified, then crushed and cleaned separately to remove impurities in the plastics, and then dried. The pre-treated crushed materials are then put into a granulator for a series of processes such as high-temperature melting, plasticization and extrusion to change the physical properties of the plastics, achieve plasticization and molding of the plastics, and finally cooled, granulated and packaged.

Since the subsequent cleaning of waste plastic granulation is carried out by rinsing, the cleaning effect of this cleaning method is poor, and the grease or glue inside the plastic particles cannot be completely cleaned, which in turn affects the subsequent recycling operations and the quality of the recycled plastic products.

Here’s how it works:

Step 1: During use, the staff uses the controller 3 to control the water circulation module 8 and the rinser 1 to start, the external crushing device puts the crushed plastic particles into the rinser 1, the water circulation module 8 injects water into the rinser 1, and the rinser 1 rinses the internal plastic particles. After the rinsing operation is completed, the rinsed plastic particles enter the net bucket 75 of the drain transfer mechanism 7 under the guidance of the guide plates 6 on both sides. The staff controls the controller 3 to start the second lifting module 72, the translation module 71, the double-end motor 76 and the elevator 2, and the second lifting module 72 drives the fixed frame 73 to rise to the specified height. The net bucket 75 and the plastic particles inside it are separated from the water. The translation module 71 drives the second lifting module 72 to move the net bucket 75 to the lifting position of the elevator 2 under the cooperation of the fixing frame 73. The double-end motor 76 drives the driving wheels 77 on both sides to rotate, so that the net bucket 75 is driven to rotate under the action of the rotating force of the driving wheel 77 and the limiting action of the limiting wheel 74 to dehydrate the plastic particles inside the net bucket 75. The dehydrated plastic particles enter the elevator 2 under the action of the rotating force of the net bucket 75, and the elevator 2 lifts the plastic particles and delivers them to the inner cavity of the water tank box 41.

Step 2: The staff controls the controller 3 to start the water circulation module 8, the electric push rod 45, the micro motor 514 and the first lifting module 42. The water circulation module 8 fills the inner cavity of the water tank box 41 with cleaning liquid. The electric push rod 45 drives the downward pressure and wave-making mechanism 5 to rotate downward with the pin rotation point with the mounting frame 44 as the vertex through its own extension, so that the pressure plate shell 51 closes the top of the inner cavity of the water tank box 41 and presses the plastic particles floating in the inner cavity of the water tank box 41 to immerse them below the water surface. The micro motor 514 drives the rotating rod 515 to rotate circumferentially, so that the rotating rod 515 drives the limiting slider 513 to move circumferentially, so that the limiting slider 513 reciprocates up and down in the inner cavity of the guide rod 512 and drives the guide rod 512 to swing with the pin rotation connection point with the second mounting frame 53 as the vertex, so that the guide rod 512 drives the rotating frame 56 to swing inward and outward along the left and right directions with the pin rotation connection point with the second mounting frame 53 as the vertex, and the rotating frame 56 drives the driving frame 510 to rotate with the limiting connection seat 5 The pin shaft rotation connection is the vertex rotation, so that the driving frame 510 drives the connecting seat 57 to reciprocate inside and outside. Since the connecting seat 57, the limit connecting seat 59, the first connecting frame 55 and the driving frame 510 form a parallelogram structure, the connecting seat 57 is prompted to drive the push plate 58 to move inside and outside under the cooperation and limiting action of the first connecting frame 55 and the limit frame 54, and then under the synchronous movement of the corrugated components on the left and right sides, waves are generated on the water surface of the inner cavity of the water tank box 41, and the waves on the left and right sides contact at the center to form a constructive interference phenomenon, so as to roll the plastic particles floating above the water into the water, and float up again under the buoyancy of the plastic particles themselves to form a cycle, so as to achieve deep cleaning of the plastic particles. After the cleaning, the plastic particles, after the downward pressure and the wave-making mechanism 5 are reset, the filter plate 43 is driven by the first lifting module 42 to move upward in the inner cavity of the water tank box 41, so as to push the plastic particles out to the inside of the water tank box 41 for subsequent collection and processing by the staff;

Therefore, the waste plastics can be further cleaned in depth after granulation and rinsing, thereby improving the cleaning effect and allowing the plastic particles to fully contact with the cleaning liquid, so as to completely remove the grease inside the plastic particles, thereby achieving the purpose of improving the quality of the plastic products recycled after subsequent recycling.
