Mixed material separation in the prior art mostly uses cyclone with device for reducing dust, but existing cyclone can only be to list
Mixed material in a pipeline carries out separating treatment, and conventional cyclone internal face is smooth, and mixed material directly washes away eddy flow
Device inner wall not only be easy to cause erosion of wall, but also stress of the mixed material in cyclone and motion conditions are relatively simple, no
Only low separation efficiency, service life are short, can't effectively reduce dust, thus the serious application for constraining separator.
Invention content
For the above-mentioned prior art, a kind of mixed material separation of present invention offer and device for reducing dust, to solve existing mixing
The technical problem that material separation device low separation efficiency, dust-laying effect are poor and device serious wear, service life are short.
In order to achieve the above object, the technical solution adopted in the present invention is：A kind of separation of mixed material and depositing dust are provided
Device, including the bionical cyclone of multichannel and injector；Wherein,
The bionical cyclone of multichannel be followed successively by from top to bottom the overflow pipe being mutually permanently connected, vortex chamber, shrink hopper and
Nesting tube；Vortex chamber sidewall upper is provided with access road, and access road includes a main channel and several subaisles, main channel
Tangent with the side wall of vortex chamber and communicate, subaisle is fixed on main channel, and is communicated with main channel；The bionical cyclone of multichannel
Internal face on bottom width is evenly distributed with as the bionic, non-smooth unit of 1cm~15cm with specific spacing；
Injector includes nozzle, mixing chamber, trunnion and diffuser casing, and nozzle one end is connect with high-pressure pump, and the other end stretches into mixed
Close chamber interior, mixing chamber bottom offers the connector being connected with overflow pipe, and with overflow pipe airtight connection, trunnion both ends point
Not with mixing chamber and diffuser casing airtight connection, diffuser casing is connected by pipeline with depositing dust case.
The access road of mixed material separation and device for reducing dust in the present invention further includes several secondary logical other than main channel
The end in road, each channel can connect different pipelines, the mixing that the to be separated or depositing dust flowed into from different pipelines is handled
Material first converges at main channel end, then from the direction of the bionical cyclone inner wall of multichannel is tangential on the initial velocity more than 10m/s
Degree flows into the inside of cyclone and does downward corkscrew motion, can be multiple to coming from using only a cyclone to meet
The mixed material of different pipelines carries out the demand of separation or depositing dust processing.After mixed material enters the bionical cyclone of multichannel,
Centrifugal force is generated in rotary course, the material that weight is more than to air-suspension gets rid of the internal face to cyclone, and material is once
Contact the inertia force that will lose screw with internal face and can rely on initial velocity momentum and downward gravity along internal face
It falls, until the bionical cyclone of multichannel is discharged from nesting tube；Meanwhile when the mixed material of screw drops to contraction hopper
When, by " eddy flow the moment of inertia " invariance principle, tangential velocity persistently increases, when mixed material reaches a certain position of contraction hopper
Afterwards, eddy flow will from bottom to top invert rising, continue to make corkscrew motion, (inside is mixed with part not from stock layout to inward turning ascending air
The little particle solid matter of pipe discharge) by the overflow pipe discharge bionical cyclone of multichannel；Therefore, in the bionical eddy flow of entire multichannel
Existed simultaneously in device external spiral down mixing material stream and inside spin from access road to nesting tube reversely rise it is secondary
Mixed airflow, under the collective effect of two kinds of screw fluids, mixed material is sufficiently separated.
In the present invention, it is disposed with bionic, non-smooth unit on the internal face of the bionical cyclone of multichannel, works as mixed material
It flows into access road by the road with certain speed and enters inside bionical cyclone during progress screw, mixed material
In vortex cyclone (cyclone due to being influenced and being formed in the interior thereof reversion by bionic, non-smooth unit of gas phase (air)
Rotation direction and mixed material flowing direction it is opposite), which has certain suspension effect, can reduce mixed material and internal face
Contact so that friction coefficient reduce, to effectively reduce mixed material kinetic energy consumption, also, invert vortex cyclone
It can play the role of cushion pad and ejection is padded, can effectively reduce erosion and abrasion of the solid phase particles in mixed material to internal face
Effect；In addition, bionic, non-smooth unit increases the roughness of the bionical cyclone internal face of multichannel, compared to smooth table
Face, mixed material reduce the erosion of internal face and corrasion, and internal face is more wear-resisting, and when solid phase particles strike it is imitative
It is easy to happen rebound after raw Non-smooth surface unit and turns to, can further weaken mixed material and the erosion of internal face is made with abrasion
With so that the service life of device greatly prolongs；In addition, bionic, non-smooth unit can weaken mixed material and the bionical rotation of multichannel
The formation for continuously contacting with face and continuous moisture film between device internal face is flowed, simultaneously because the vortex cyclone of reversion exists, can avoid
Mixed material adheres on the bionical cyclone internal face of multichannel, to also realize the anti-sticking effect with desorption.
The working media of injector in the present invention and overflow pipe airtight connection, injector injection can be gas phase or liquid
Phase, the Involving velocity generated by ejection medium can generate suction to the secondary ascending air and mixed material being discharged from overflow pipe
Effect can further promote the bionical cyclone of multichannel to mixing to enhance the rising effect of ascending air and mixed material
The separative efficiency and effect of material.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the bionic, non-smooth unit on access road, overflow pipe and nesting tube internal face in annular shape, and with enter
The axis direction in mouth channel, overflow pipe and nesting tube is perpendicular, and the bionic, non-smooth unit on vortex chamber internal face is in striated,
