Description
Technical field
The utility model is related to the silicon material sorting technology of photovoltaic or semiconductor applications, especially a kind of cyclone type silicon material sorting
Equipment.
Background technology
Silicon raw material purity at present required for solar energy single crystal stove is higher, and typically more than 99.9999%, purpose is exactly to be
Improve single crystal growing furnace crystal bar utilization rate.Single crystal growing furnace requires silicon raw material so harshness, and main cause is exactly that the impurity in silicon raw material is straight
Impact crystal bar crystal forming rate is connect, impurity content height is likely to result in single crystal growing furnace cannot grow monocrystal rod.
The silicon material that at present single crystal growing furnace is used is all import original silicon material substantially, based on cost pressure, import original silicon material unit price one
It is straight high, it is reduces cost, substitute import original silicon material using domestic silicon material or low-cost fluid bed silicon material.But
Impurity is more in domestic silicon material or fluid bed silicon material, directly using impact single crystal growing furnace crystal bar crystal forming rate.
Method for separating in prior art for domestic silicon material or fluid bed silicon material has two kinds：The first, using artificial hand
Work point is selected, and the method sorting quality is high, but extremely inefficient.Second, the method directly inhaled using dust catcher during charging is sorted,
The method efficiency is than artificial separation efficiency high, but sorting quality is poor, easily causes silicon material secondary pollution.
So, how a kind of silicon material screening installation is provided, problems of the prior art are solved, realize that silicon material dust is miscellaneous
The separation of matter, is current those skilled in the art technical problem urgently to be resolved hurrily.
Utility model content
In view of this, the utility model provides a kind of silicon material screening installation, solves defect present in prior art, tool
Body scheme is as follows：
A kind of cyclone type silicon material screening installation, it is characterised in that：Including whirlwind tower, feeding portion and the throttling of the whirlwind tower
The outlet connection of valve, the entrance of the choke valve is connected with blower fan, and the feeding portion of the whirlwind tower is also associated with loader, described
The discharging portion lower section of whirlwind tower is provided with collector.
Specifically, the loader includes being vertically welded in the feeding groove in the feeding portion, and hangs down with the feeding groove
The hopper for directly welding together.
Specifically, the collector is slot type, is vertically set at the discharging portion lower section 30cm.
Specifically, the both sides of the collector are provided with lifting ear.
Specifically, the whirlwind inner wall of tower scribbles coat of silicon carbide.
Preferably, 5 times of a diameter of discharging portion diameter in the feeding portion.
Preferably, the choke valve controls gas flow size by micro computer.
The utility model compared with prior art, this have the advantage that：1st, the setting of air outlet choke valve can adjust rotation
The size of interior rotational airflow and outer rotational gas flow in wind tower is big such that it is able to sort variable grain using the size of throttle valve opening
Little silicon material.2nd, whirlwind inner wall of tower scribbles coat of silicon carbide, so as to cause secondary pollution when avoiding silicon material secondary sorting.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing wanted needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only this

Fig. 2 is the schematic diagram of silicon material sorting.
In figure：10th, whirlwind tower 11, feeding portion 12, discharging portion 20, loader 22, feeding groove 22, hopper,
30th, choke valve 31, outlet 32, entrance 40, collector 41, lifting ear.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Referring to shown in accompanying drawing, the cyclone type silicon material screening installation structural representation that Fig. 1 is provided for the utility model, Fig. 2 is
The schematic diagram of silicon material sorting.
The utility model is claimed a kind of cyclone type silicon material screening installation, including whirlwind tower 10, the whirlwind tower 10
Feeding portion 11 is connected with the outlet 31 of choke valve 30, the entrance 32 of the choke valve 30 and blower fan（It is not shown）Connection, the rotation
The feeding portion of wind tower 10 is also associated with loader 20, and the lower section of discharging portion 12 of the whirlwind tower 10 is provided with collector 40.
Silicon material Jing loader 20 to be sorted sends into whirlwind tower 10, opens blower fan, by adjusting silicon material blanking velocity, air outlet
The flow of choke valve 30, the aperture of discharging opening 12, the size of outer rotational gas flow and interior rotational airflow in control whirlwind tower 10, so as to reach
The purpose of sorting different size silicon material and dust.
Specifically, the loader 20 includes being vertically welded in the feeding groove 21 in the feeding portion 11, and defeated with described
The vertical welding of hopper 21 hopper 22 together.
Specifically, the collector 40 is slot type, is vertically set at the lower section 30cm of the discharging portion 12, certain when sorting
After specification silicon material is finished, in that context it may be convenient to withdraw from collector 40, the collector 40 for more renewing carrys out splicing.
Specifically, the both sides of the collector 40 are provided with lifting ear 41.
Further, the inwall of the whirlwind tower 10 scribbles coat of silicon carbide, it is to avoid other metals during silicon material secondary sorting
Being mixed into for composition, causes secondary pollution.
Further, 5 times of a diameter of diameter of discharging portion 12 in the feeding portion 11, it is ensured that whirlwind tower has preferable
Separating effect.
Further, the choke valve 30 controls gas flow size by micro computer.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
