Abstract

The utility model relates to a subdivision device for subdividing the light refuse mixed by plastic films, papers and leaves. The mixed refuse passes through a high-voltage electrostatic field so that the plastic films are loaded with charges and are mutually attracted with the transferring machines with opposite charges arranged on both sides of the electrostatic field, and the transferring machines will bring the plastic films out of the electrostatic field; then a cleaning brush is used to separate the plastic films from the transferring belts. Meanwhile, the papers and leaves without or with less charges pass through the electrostatic field and fall into a collecting hopper under the device so as to be separated. The utility model adopts the high-voltage electrostatic field to enable the material which needs to be separated to be loaded with charges and as the material to be separated is loaded with a large quantity of charges, the material to be separated is more attracted to the transferring machine so as to be completely separated.

Description

A kind of lightweight rubbish subdividing device

Technical field

Utility model relates to a kind of garbage sorting device, especially relates to the rubbish subdividing device that the paper in the lightweight rubbish, plastic sheeting, leaf etc. effectively can be separated.

Background technology

Garbage disposal at first needs rubbish is carried out sorting, then handles respectively according to the different rubbish that sub-elect, as recycling.Yet common refuse classification equipment such as winnowing machine can only carry out rough sort with rubbish, are about to lightweight rubbish such as leaf, paper, plastic sheeting etc. and separate with heavy rubbish.Yet the paper in the lightweight rubbish, plastic sheeting etc. are still mixed, can not reach to each have with handling, and are unfavorable for the subsequent treatment of recovery of resources and rubbish.Chinese patent 88100769 disclose a kind of from separating of garbage again with insulating properties material fragment for example plastics and/separation equipment that paper separates, it is to utilize friction to make electrostatic charge on wherein the plastic flakes band, by the transhipment recipient of a band reversed charge plastic flakes that is in the static electrification lotus of fluidisation or suspended state is extracted (absorption) from material flow again and come out, thereby reach separating plastics and paper.Yet this equipment, owing to only make plastic flakes carrier band electric charge by friction, thereby the plastics carrier band quantity of electric charge is little, and the attraction between the transhipment recipient of oppositely charged and disposal ability are also just little, separating effect is not really desirable; Secondly, the fluidisation of material to be separated need dispose more powerful air blast, has increased equipment dynamic consumption.Therefore still having is worth improved place.

Summary of the invention

The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of power consumption little, and separation of material electric charge carrier band amount is big, and separation and disposal ability are strong, the lightweight rubbish subdividing device that can directly effectively plastic sheeting in the lightweight rubbish be separated with paper.

The utility model purpose realizes that main the improvement is to utilize all kinds of material static electrification performance differences in the rubbish, makes its stream that looses by a high voltage electric field, and electrostatic charge on plastic sheeting wherein is with in electric field is and with the transporter absorption of opposite electrostatic charge and take electric field out of; And paper, leaf be owing to be with basically or seldom electrically charged, thereby directly pass electric field and fall to aggregate bin, thereby realize effectively separating of plastics and paper, leaf.Specifically, utility model lightweight rubbish subdividing device, comprise the categorised collection aggregate bin, separate conveyance and remove cleaning brush, it is characterized in that the electrostatic field casing that the aggregate bin top has belt electrode rod upper and lower opening to be used to lead to, said separation conveyance is arranged on electric field casing side, and electrode bar and conveyance connect the both positive and negative polarity of power supply respectively.Mixed material is scattered by electrostatic field casing top, plastic film chip is by the carrier band electrostatic charge in the high-voltage electrostatic field, and taken out of electric field with conveyance by the absorption of the conveyance of oppositely charged, fall into the below aggregate bin by removing the cleaning brush brush, not with or little charged paper, leaf then free-falling pass the aggregate bin that electric field falls into the below, thereby reach the separation of two classes.

For improving separative efficiency, vibration or vibration doffer can be set on the utility model separator, make compound enter the electrostatic field casing, favourable like this separation with loose diffusing stream mode; Rubbish to be separated preferably earlier cracks into platelets with it simultaneously, and tiny like this lamellar body just can be separated it with smaller suction, can reduce electrostatic field power.The said cleaning brush of utility model, a kind of better way is that it is electrically connected with electrostatic releaser, helps plastics carrier band electric charge is discharged, thereby avoids plastic sheet static electrification and hopper generation Electrostatic Absorption.The said transhipment band of utility model, a kind of better is to attract the face (lateral surface) of contact plastic sheet to make at traffic direction to be concavo-convex alternate structure, Dui Ying cleaning brush is also made complementary with it concavo-convex broach shape with it, this structure more help being adsorbed on transhipment with on plastic sheeting and the separating of transhipment band, can avoid plastics to gather transhipment simultaneously and be with stuck.

Utility model needs separating part material carrier band electric charge owing to adopt the high-voltage electrostatic field to make, thereby the separation of material carrier band quantity of electric charge is big, attraction is just big between separator and conveyance, can not only effectively from composting, film be separated with leaf with paper, and separate thoroughly, be convenient to the categorised collection utilization, can bring into play refuse effectiveness in the rubbish to greatest extent.Material is scattered from top to bottom naturally also can omit goods fluid device and power.Utility model not only can be used for separating of plastic sheeting and paper in the rubbish, but also can be used for other can add the static electrification lotus with not with or the separating of few static electrification lotus material.

Below in conjunction with the description of a non-limiting example embodiment, further specify the utility model structure, but embodiment not the qualification to the utility model concrete structure.
