Description

Selection by winnowing cyclone

Technical field

The utility model relate to be separated that two kinds of different specific weights mix material in selection by winnowing mode clean separator, more relate to cyclone and clean separator.

Background technology

For the grain separating cleaning after threshing or cereal shelling, threshing, hulling device are equipped with cleaning plant, for grain is cut broken shell and screened with assorted, is separated.Existing cleaning plant is mainly vibratory sieve sorting mechanism, and matching purge blower fan, be convenient to the seed vibration screenings such as grain, maize, Chinese sorghum out.But in whole vibration screening operation process, seed, comprise shell and cut and can fly away everywhere with the wind, cause equipment working environment dust comparatively large, there is the technical problem of seed waste; The most key, there is screening in vibratory sieve sorting mechanism, separating power is poor, causes impurity content in grain many, also need selected further, thus raise processing cost.Existing cyclone is mainly as the separation dust arrester purified air, and its volume is large, it is large to take up room, energy consumption is large, is difficult to adapt to be similar to grain and shell and cuts that different specific weight material is mixed is mutually separated use, the technical problems such as separating power is on the low side, operating noise is large.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of efficient, particle that high-quality completes two kinds of different material density or the selection by winnowing cyclone that powder is separated, cleans, purifies.The selection by winnowing cyclone technical scheme that the utility model provides, its main technology contents is: a kind of selection by winnowing cyclone, its cyclone shell internal fixtion suspends and is provided with cone inner core, described cyclone shell is by upper conical shell, cylinder between inferior pyramidal shell and two conical shell connects and composes, upper conical shell central authorities are air inducing outlet, inferior pyramidal shell central authorities are blanking outlet, compound pan feeding passage passes into cyclone housing by tangential direction, described cone inner core is by coaxial line, upper cone and the lower cone of bottom surface docking are formed, the mouth that passes into of pan feeding passage docks place horizontal position lower than the upper cone of cone inner core with lower cone.

In above-mentioned overall technical architecture, the upper cone vertex of a cone angle of cone inner core is greater than lower cone vertex of a cone angle.

Selection by winnowing cyclone technical scheme disclosed in the utility model, the setting of cone inner core in cyclone housing, to the pneumatic amount in it, comprise distinguished and admirable, wind speed and blast gives from new layout, this structural configuration meets the stalling characteristic of the material of the two kinds of different specific weights mixed, and improves selection by winnowing efficiency and separating cleaning quality, and greatly reduces cyclone volume, take up room little, operating noise is low, energy consumption reduce, there is range of application technological merit widely.

Detailed description of the invention

Selection by winnowing cyclone disclosed in the utility model, it is formed as shown in the figure, cyclone housing is formed separation by cylinder 3 connection between upper conical shell 1, inferior pyramidal shell 2 and two housings 1,2, is cleaned housing, upper conical shell 1 central authorities are air inducing outlet 4, air-introduced machine is connected through induced pipe 5, the central authorities of inferior pyramidal housing 2 are blanking outlet 6, and the pan feeding passage 7 of mixed material passes into cyclone housing by tangential direction.

Suspended by suspension 11 in cyclone housing and fix a cone inner core 10.This cone inner core 10 is by coaxial line and the upper cone 9 of bottom surface docking and the Double-conical-surface body that forms of lower cone 8, the cone surface of upper/lower cone 9,8 forms circumference axial passage with the upper conical shell 1 of cyclone, inferior pyramidal shell 2 respectively, gives from new distributing distinguished and admirable, the wind speed of cyclone housing and blast.In this enforcement structural design, the vertex of a cone angle of upper cone 9 is greater than the vertex of a cone angle of lower cone cone 8, and the horizontal position N of upper/lower cone 9,8 bottom surface docking is higher than the pan feeding passage 7 entrance position of cyclone housing.Mixed material enters the moment of cyclone housing, wherein lay particular stress on material percussion lower cone 8 conical surface, while its kinetic energy is significantly consumed, the guide channel formed by lower cone 8 and inferior pyramidal shell 2, upper sector-style is skewed arranges guiding, pneumatic up reaction force attenuation, and be positioned at, lower cone 9, the air channel that horizontal position N are docked downward in 8 bottom surfaces is broadened by narrow, and the vertex of a cone angle of lower cone cone 8 is little, wind speed is more in sluggish trend, three aspect effects, the more favourable sinking of material that density is bigger than normal and turn are sunk, feed separation less than normal with density, fall along inferior pyramidal shell 2 rotating separation, the partially light material of density, as broken shell is cut, upper sector-style is concentrated in mixed material inlet port position, the partially light material in mixed material is easier to blow floating, bring in the guiding air channel formed between upper cone 9 and upper conical shell 1, then brought into air inducing outlet 4 by concentrated, complete and lay particular stress on thoroughly being separated of material.Its separative efficiency improves greatly, and volume reduces greatly, be separated, cleaning energy consumption low.
