ES2277753B1 - RECYCLING PROCESS OF AGRICULTURAL AND URBAN PLASTICS. - Google Patents

Abstract

Recycling process of agricultural plastics and urban.

1. Plastics are classified by moving to sieves and blowing for cleaning without using water in its washing thus ensuring spills pollutants

2. Plastics pass to the crusher.

3. Plastics, once crushed, pass to a rotating autoclave where they perceive heat. They are then poured to a volumetric scale from which you pass a hydraulic press in which the molds are subjected to pressure and heat.

4. Once the desired density is achieved, the Plates are released and stored.

5. The main feature and innovation of This process is to create a product using different types of plastics without the need to wash them previously with water but yes subjected to dry cleaning through a sieve and a system air injection that by shaking eliminates much of the  dirt that accompanies plastics.

Description

Recycling process of agricultural plastics and urban.

Background

The processes currently in existence they have washing stages that in addition to increasing costs They produce wastewater that is polluting For the enviroment.

With this new invention a new one is achieved innovative system that helps to end the ecological problem which involves the abandonment of agricultural plastics, as well as a environmentally friendly and economically viable treatment for eliminating a series of costs that so far have been occurring in other plastics recycling processes.

Detailed description of the invention

1. Plastics selected for the process Recycling are agricultural and urban plastic waste.

2. Plastics, once received at the plant, are classified according to their densities and passed to the screens and blown for cleaning them.

3. Plastics go to a mill shredder

4. Plastics, once crushed, would pass to a rotating autoclave inside which will be subjected to heat to soften it and thus achieve easy product malleability plastic that is poured into the mold to be subjected to heat and pressure by a hydraulic press whose base plate and plate upper thrust will be provided with electrical resistors incandescent

5. The pressure is exerted on two plates provided with incandescent resistors, a bottom plate that is fixed and another top plate which is what makes the function of pressing  on the mold supported on the bottom plate, until the adequate density, at which time the piece obtained is released and stored

6. The main feature and innovation is that plastics can be mixed without being washed, but subject to dry cleaning through a sieve of sieve, where the heaviest waste is released, and a system of air blowing that by shaking eliminates much of the dirt that accompanies plastics, thus remaining a number of elements attached to plastics that act as loads, that is, as an additive that gives body and adds strength to the final product acting as a stabilizer, by maintaining the technical properties, both mechanical and electrical and also chemical

Claims (5)

1. A process in which upon receipt of the plastic is screened and cleaned by air blowing in dry, to later become crushed, later it passes to a autoclave in which the plastic is subjected to heat. One time obtained the appropriate temperature passes to a volumetric scale and it is poured into a mold into which it is pressed at the same time which is subjected to heat, by means of incandescent resistances placed on the base plate and the press thrust plate hydraulics that puts pressure on the plastic introduced in the mold achieving the necessary density. 2. A process according to claim 1, which It comprises the following stages:

to)

The Plastics are received and classified according to density.

b)

He plastic passes to a sieve screen where the waste is sifted heavier and dry cleaned through a blower air.

C)

He Plastic passes to a grinder mill.

d)

He Crushed plastic is introduced into the autoclave where it is subjected to heat controlled

and)

He plastic passes to a volumetric scale, which pours the product plastic inside a mold.

F)

He plastic that is poured into the mold is subjected to heat and pressure by a hydraulic press whose base plate and push plate upper will be provided with incandescent electrical resistors which are the ones that provide heat to the plastic poured into the mold.

g)

The piece is detached from the mold and passes to the area of storage.

3. A process, according to claim 2, in the that the plastic is dry cleaned by blowing and screening without be washed previously. 4. A process, according to claim 2, in the that thanks to the previous phase of screening and blowing, indicated in the claim 3 eliminates the risk of contamination by spills of contaminated water. 5. A process, according to claim 3, in the that, when not being washed, remains of elements attached to the plastics that act as charges thereof, giving body and adding strength of the foral product acting as a stabilizer, by maintaining the technical properties, both mechanical and electrical and also chemical
