Description

Melting equipment in foamed plastic recycling granulation

Technical Field

The utility model relates to a foamed plastic melts equipment technical field, specifically is a foamed plastic retrieves equipment of melting in the granulation.

Background

The foamed plastic is a high polymer material formed by dispersing a large number of gas micropores in solid plastic, has the characteristics of light weight, heat insulation, sound absorption, shock absorption and the like, has dielectric properties superior to matrix resin, and has wide application range. Almost all kinds of plastics can be made into foamed plastics, and foam molding has become an important field in plastic processing.

Because the foam plastic is not easy to degrade, in order to prevent and control environmental pollution, the useless plastic foam is generally recycled and then melted again in a furnace to be made into a new product by using a mold. If the melting equipment does not melt the foam plastics fully or uniformly, the appearance and the appreciation degree of the remanufactured product are affected, so that the novel product is uneven, and the scrappage is increased. In order to ensure that the liquid melt discharged from the discharge port is completely melted, a filter plate is generally arranged at the discharge port, so that the plastic which meets the standard can pass through, and the plastic which does not meet the standard is continuously melted.

However, the existing melting equipment is only provided with one filter plate for filtering the melting liquid, the foam plastic needs to be melted into extremely small particles from a very large volume in one melting cavity, the intermediate span is too large, the particles with large volume difference are mixed in the same melting cavity, the melting is not uniform, the melting cavity is blocked, and the melting efficiency is reduced.

Based on this, the utility model designs a foam retrieves melting equipment in the granulation to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme:

As a further proposal of the utility model, the inlet pipe is gradually kept away from to first filter, second filter and third filter.

As a further aspect of the utility model, the filtration pore diameter on first filter, second filter and the third filter reduces gradually. During operation, the farther the distance from the feeding pipe is, the more thoroughly the foam plastic is melted, the smaller the particles are, the pore size is gradually reduced, the discharged materials are qualified, and meanwhile, the pressure of the cavity before melting can be relieved, so that the foam plastic solution can quickly enter the rear cavity to continue to melt.

As a further aspect of the present invention, the distance between the third filter and the second filter is smaller than the distance between the second filter and the first filter. When the device works, the foam plastic is melted more thoroughly along with the gradual distance from the feeding pipe, the molecular gap is smaller, and the occupied space is smaller.

As a further proposal of the utility model, the slide plate is positioned on the left side of the inlet pipe when the crank is positioned on the right end. When in work, the foam plastic is prevented from entering the left side of the sliding plate and causing leakage.
