Description

Dust removal equipment mixed in plastic scrap

The present invention relates to a dust removal apparatus mixed with plastic scrap, and more specifically, to remove dust generated in the process of pulverizing waste plastic by a dust container equipped with a cyclone filter to facilitate the removal of dust, In addition to preventing dust from being collected in the collected dust and the exhausted air, the air is not only exhausted, but the dust inlet is eccentrically configured to obtain a cyclone effect upon inhalation of dust, thereby improving dust suction power. The present invention relates to a dust removal apparatus mixed in a plastic scrap.

In general, plastics initially appeared as substitutes for metal, wood, glass, ceramics, leather, etc., but have light weight, toughness, corrosion resistance, colorability, mass production potential, and because of their excellent workability, electrical, electronic, mechanical, construction In addition, as an essential material in other fields, it is firmly occupying the position as a new material instead of a substitute.

Such plastics are used in various fields due to their ease of molding, but there are also serious problems related to waste plastic disposal used and discarded as many fields of application are used.

In addition, plastic wastes generated from industrial wastes, including household waste in general households, have caused serious problems in their disposal, and plastic wastes are collected separately, but it is almost impossible to properly recycle them. Plastic waste has been selected and landfilled.

Accordingly, waste plastics are suppressed by producing products using waste plastics.By discoloring and coloring them according to the color of the products to be produced, they are recycled in the production of plastic products. It prevents pollution and soil pollution, solves the difficulties of selecting landfills, and saves foreign currency by replacing huge amounts of plastic raw materials imported for plastic products.

In addition, during injection molding of plastic products, sprues and runners are generated when the products are molded, which are eventually processed as scrap.

This generated scrap is disposed of or recycled by mixing with new material. The scrap is crushed by a grinder to make small particles, and then mixed with the new material.

However, in the process of crushing and mixing scraps, plastic dusts such as fine dusts are generated, and the dusts may be mixed and contained in the mixture, and molding may be performed. It is unstable, and the physical properties such as strength of the product are lowered, and eventually it is disposed of or used to remove dust by hand (using a sieve).

This is pointed out as a vicious cycle of reducing dust removal rate, polluting the surrounding environment, harming worker's health, lowering productivity, and increasing raw material cost and management cost.

On the other hand, in order to solve this problem has been devised a dust collection device of the plastic scrap of the Patent Publication No. 10-2011-0037535, which is the hopper which is formed in the upper end to receive the waste plastic pulverized from the crusher, The separation chamber is formed in a cylindrical shape and connected to the lower side of the hopper to open and close the hopper by a damper, and the bottom surface is formed of a perforated plate so that dust is dropped and a scrap discharge port is formed at one lower end of the hopper. The waste container is connected to the discharge port for receiving the scrap discharged by opening and closing by the shutter, and attached in the form of narrowing from the lower end of the separation chamber to the lower side and a dust outlet is formed at the lower end to the dust falling from the separation chamber The dust collection chamber to be stored and the separation chamber It consists of a frame that supports from.

The prior art thus constructed can stably collect and process dust generated during crushing for recycling plastic scrap, can be installed and used in a narrow space, and can maintain a clean environment while drastically reducing the number of workers. I expect a useful effect.

However, the prior art Patent Publication No. 10-2011-0037535, because the configuration is complicated, there is a problem that the manufacturing cost is high, there is a problem that the installation cost is increased accordingly.

In addition, since the dust of the scrap is dropped into the separation chamber as it is separated there is a problem that the dust is blown in the process of removing the dust separated in the separation chamber causing respiratory diseases such as workers.

In addition, as the metal contained in the plastic is not caught at all in the process of crushing the plastic, there is a problem in that the work of separating the metal separately during reuse of the crushed plastic scrap has to be further performed.

In addition, since the dust generated during the crushing of the plastic scrap is removed by the natural fall due to the perforated plate, there is a problem that the workability of dust removal is greatly reduced.

The present invention has been made to solve the problems caused by removing the dust generated when the conventional waste plastic scrap is pulverized, the dust generated during the crushing of the scrap is forced to be sucked by the suction body, By connecting the dust container, the cyclone filter is provided inside the dust container to filter the dust by the cyclone filter, so that the air exhausted to the outside can be kept more clean, and the magnet is further It is possible to omit the additional metal screening process by sorting the metals contained in the crushed scraps by the magnetic force of the magnet, and to configure the dust intake in which dust is sucked out so that the cyclone air is generated so that the suction force of the dust Dust mixed in one plastic scrap for great improvement There are going to provide a device that purpose.

Dust removal apparatus mixed with the plastic scrap of the present invention as a means for achieving the above object, the housing body is provided with a hopper into which the plastic scrap is put; A scrap moving body which is connected to the lower part of the housing body and dropped into the scrap, and has a residual amount discharge port and a dust suction hole through one side of the remaining amount discharge port at the lower portion thereof; A conveying body constructed in the scrap moving body and connected with a driving motor, the conveying body being screwed to convey the scrap injected into the scrap moving body by being rotated by the rotational force of the driving motor; A suction network fitted to one outer surface of the scrap moving body positioned in a direction corresponding to the driving motor and installing a dust suction port of the scrap moving body; A scrap guide coupled to the outside of the suction net and guided by crushed scrap; A scrap collector connected to the scrap guide to collect scrap discharged through the scrap guide; A dust suction pipe connected to one side of a dust suction hole of the scrap moving body; A dust cylinder connected to the other side of the dust suction pipe and having a cyclone filler therein; A vacuum suction pipe having one side connected to the dust cylinder; It comprises a vacuum suction body is connected to the other side of the vacuum suction pipe.

The vacuum suction pipe is further connected to an exhaust filter body having an exhaust filter therein.

In addition, the remaining amount discharge port of the scrap conveying body is further connected to the remaining amount discharge pipe connected to the scrap collecting body.

In addition, the dust suction port is eccentric to one side from the conveying body provided inside the scrap moving body so that the dust suction input is increased by the cyclone phenomenon is generated by the suction air sucked by the dust suction pipe connected to the dust suction port is increased. Formed.
