Driving type pulse pneumatic separation equipment
Technical field
The present invention relates to driving type pulse pneumatic separation equipment, be particularly useful for the sorting of solid waste, also be applicable to the material sorting of agricultural production, mineral processing.
Background technology
Pneumatic separation all has the precedent of application at mining industry, agricultural, solid waste separation field.For traditional pillar pneumatic separation, the terminal velocity of sorting component is the principal element of the decision efficiency of separation.The terminal velocity of particle is relevant with the granularity of particle, shape and density, thereby it is more to influence the factor of sorting, and traditional sorting unit structure is single, mainly is made up of blower fan and selection by winnowing post, is difficult to realize that wide grade multi-component masses effectively separates by density.In order to improve the efficiency of separation, before sorting, need material is carried out narrow classification; Or after fragmentation makes epigranular, make it carry out sorting, and require bigger by the density contrast of sorting material by density contrast.Shape by the sorting component also has a significant impact the efficiency of separation, and for the material below the 2mm, the conventional air sorting unit efficiency of separation is extremely low.Because actual sorting material is in granularity with differ greatly in shape, the terminal velocity of concentrate and tailings is often overlapped, has caused the efficiency of separation of conventional air sorting unit lower, can't realize the separation of taking as the leading factor with density.
Summary of the invention
Problem in view of the prior art existence, the purpose of this invention is to provide a kind of wide grade, multi-component masses driving type pulse pneumatic separation equipment by the effective sorting of density, make the different particle of density in assorting room, obtain acceleration, retarding efffect by pulse pneumatic, realize effective sorting of taking as the leading factor with material density difference.
Driving type pulse pneumatic separation equipment of the present invention, it comprises sorting unit and cyclone dust collectors, it also comprises the air feed system that links to each other with sorting unit, the pipeline that air feed system connects sorting unit is provided with the pulse pneumatic converter, will set the bottom of the pulse pneumatic introducing sorting unit of required waveform by the pulse pneumatic converter; Be provided with the air distribution plate that pulse pneumatic is evenly upwards floated in the selection by winnowing post of described sorting unit, the middle part of selection by winnowing post is provided with charging gear, and its bottom is provided with the batch (-type) discharge valve by solenoid control.
Driving type pulse pneumatic separation equipment of the present invention, described air feed system is made of blast machine, air flow valve and the spinner flowmeter of blower fan, the blower fan that is linked in sequence; Described pulse pneumatic converter is made up of the motor and the frequency modulator of flutter valve, control flutter valve, and the rotor of flutter valve is a video disc, and video disc can be circular, can be semicircular, also can be the breach circle; Described charging gear is made up of motor-driven cylinder and the conveyer belt that is located on the cylinder, and conveyer belt is provided with the deep bead that prevents that selection by winnowing post feeding mouth from leaking out.
Driving type pulse pneumatic separation equipment of the present invention, be best suited for the sorting of solid waste, adopt sorting unit, air feed system and cyclone dust collectors, the pulse pneumatic converter is set, pulse pneumatic is introduced the selection by winnowing post, the material that density the is different layering of will in sorting unit, vibrating.Make the different particle of density in assorting room, obtain acceleration, retarding efffect by pulse pneumatic, realize effective sorting of taking as the leading factor with material density difference.This equipment efficiency of separation height, the sorting operating condition is wide, separation velocity is fast, all can carry out sorting by the pulse pneumatic sorting unit to different kinds of metals product or nonmetal product such as plastics, resin, fiber etc., realizes that wide grade, multi-component masses carry out effective sorting by density.Equipment efficiency of separation height, simple to operate, energy consumption is little, compact conformation, assorting room is pollution-free, has a wide range of applications in agricultural production, mineral processing, solid waste sorting, separating substances recovery field.

The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
Driving type pulse pneumatic separation equipment of the present invention, it is mainly by sorting unit, air feed system and cyclone dust collectors 11 are formed, air feed system is by blower fan 1, blast machine 2, air flow valve 3, spinner flowmeter 4 is formed, sorting unit is by selection by winnowing post 10, charging gear 7, air distribution plate 9 and weight material outlet are formed, charging gear 7 is located at the middle part of selection by winnowing post 10, air feed system is connected the bottom of selection by winnowing post 10, air feed system is connected on the pipeline of selection by winnowing post 10 and is connected with the pulse pneumatic converter that can carry out frequency modulation, the pulse pneumatic that the pulse pneumatic converter will be set required waveform feeds in the selection by winnowing post 10 of sorting unit, air distribution plate 9 is located on the air feed mouth of selection by winnowing post 10 bottoms, and the pulse pneumatic of feeding is evenly upwards floated.Selection by winnowing post 10 bottoms are provided with the batch (-type) discharge valve 8 by solenoid control, so that discharge heavy product; Top is provided with the light product material comb that is communicated with cyclone dust collectors 11, is provided with air exhauster in the comb, to strengthen the discharge to light product material.The motor of pulse pneumatic converter flutter valve (5), control flutter valve (5) and frequency modulator (6) are formed, and flutter valve 5 is made of rotor, stator and valve body, has slotted eye on rotor and the stator, rotor is a video disc, video disc can be circular, can be semicircular, also can be the breach circle.Flutter valve 5 is by Electric Machine Control, and the big small frequency of pulse pneumatic is by frequency converter 6 controls, when air communication is crossed flutter valve 5 with in the continuous pulsation air-flow input sorting unit that is produced, by the layering of in sorting unit, vibrating of sorting component.Charging gear 7 is made up of motor-driven cylinder 12 and the conveyer belt 13 that is located on the cylinder, and conveyer belt is provided with the deep bead 14 that prevents that selection by winnowing post 10 feeding mouths from leaking out.Selection by winnowing post 10 can be connected to an integral body by flange by the more piece short column, also can directly be a column length body, and its height can be set according to on-the-spot actual needs.Carry out rectification by 2 pairs of air-flows of blast machine, make steady air current, and the pressure of increase air-flow, regulate air flow valve 3 and frequency converter 6, low-density plastic paper is discharged from the top of selection by winnowing post 10 as light component enter cyclone dust collectors 11, highdensity plastic bottle falls to the bottom of selection by winnowing post as heavy ends, discharges from discharge valve 8.
