Description

Automatic dedusting filtering device
Technical field
The present invention is on monocrystalline silicon growing furnace field, more particularly to automatic dedusting filtering device.
Background technology
Single crystal growing furnace is a kind of electric resistor heating type semi-conducting material smelting furnace, is under inert gas shielding, using graphite electricity The method of heating is hindered, many product silicon are melted, the special equipment of dislocation-free single crystal silicon is grown with flexible axle direct method.In recent years, with Developing rapidly for photovoltaic solar industry, expands day by day to the demand for improving single crystal growing furnace crystal pulling benefit, particularly domestic to have extensively Wealthy market.Single crystal growing furnace is during crystal pulling, and extract system always can detach the gas in stove, stable gas pressure in holding furnace. But the dust impurities such as oxide are mixed with gas, larger shadow can be used for by entering in the vavuum pump of extract system Ring, the impurity such as timely and effective oxide powder dust removed in gas can improve single crystal growing furnace crystal pulling benefit.
During single crystal growing furnace drawn monocrystalline silicon, extract system can be had been under working condition, make stable gas pressure in stove. But, during crystal pulling, some oxides can be produced in stove, is mixed in gas and is discharged out of the furnace by extract system.Work as oxide Enter in the vavuum pump of extract system, can adsorb in pump oil, influence the normal work of pump.
Existing dedusting method is that a netted filter is fixed in inside by a dust arrester before gas is pumped into vavuum pump Core, for filtering the impurity such as oxide powder dust.But it is due to that the impurity such as single crystal growing furnace oxide powder dust are more, existing filter core is in length Easily make the impurity absorptions such as oxide powder dust on filter core in the case of time service, cause air pressure in Airflow obstruction, influence stove.Cause This, single crystal growing furnace often completes a crystal pulling, it is necessary to which the scale removal process for carrying out the cleaning of one-time dedusting device, especially filter core is more tired of It is trivial, it is time-consuming longer, crystal pulling efficiency is had a certain impact.This dedusting method is because time-consuming, lost labor, clear up loaded down with trivial details etc. Reason, is gradually eliminated by everybody, is developed a kind of single crystal growing furnace that can improve and is furthered the dust arrester of efficiency, market prospects are had an optimistic view of.
The content of the invention
It is a primary object of the present invention to overcome it is of the prior art it is not enough there is provided one kind can long-play use, Reduce dismounting, the dedusting filter of the time of cleaning.In order to solve the above technical problems, the solution of the present invention is:

The dedusting tank body is the cylindrical structure tank body of inner hollow, and the top of dedusting tank body passes through sealing of tank cover;Institute State bearing (cylinder at the axle of the surfaces of revolution of dedusting tank body:There are a boning out and one dynamic in approximately the same plane Line, when this plane rotates a circle around this boning out, face formed by this moving-wire is called the surfaces of revolution, this boning out The axle of the surfaces of revolution is done, this moving-wire is called the bus of the surfaces of revolution), the filter core is arranged in dedusting tank body and installed in bearing On;
The driving original paper includes reductor, motor, rotary shaft, and reductor and motor are fixed on cover, and utilization turns Moving axis is flexibly connected by the hole of cover with the rotating shaft of cartridge top, and motor can drive the bearing in filter core to rotate, and then is driven Filter core is rotated;The driving original paper is in tank lid lifting, rotation, and rotating shaft that can be automatically with cartridge top is disengaged, so that with cover One lifting, rotation;
An air inlet and a gas outlet are had on dedusting tank body, the gas out of air inlet enters dedusting tank body Body, can be filtered impurity (oxide powder dust etc.) in dedusting tank body by filter core;The hairbrush is arranged on the interior of dedusting tank body On wall, it can brush impurity of the absorption on filter core;The bottom of dedusting tank body side surface is additionally provided with two dust removal ports, heavy for clearing up Impurity of the product in dedusting tank base;
The tank lid lifting mechanism includes being oriented to rotary shaft, spiral lift, mounting seat, cantilever, bearing A;It is described to be oriented to Rotary shaft is fixed on the side of dedusting tank body, and centre realizes the rotation for being oriented to rotary shaft using bearing A;The spiral lift leads to Cross mounting seat to be fixed in guiding rotary shaft, cover is connected by cantilever with spiral lift, by controlling spiral lifting The lifting of machine, can realize the control to tank lid lifting;Cover can be rotated by being oriented to rotary shaft rotary shaft, for outwarding winding Cover carries out changing filter core and hairbrush.
As a further improvement, the filter core uses the filter core of the close network structure of stainless steel (by the mesh for adjusting filter core Number can change the filtering accuracy of dedusting tank, and highest filtering accuracy can reach more than 2.5 μm), the volume of filter core is dedusting tank The 4/5 of internal cavity volume.
As a further improvement, the air inlet is arranged on the top of dedusting tank body side surface, and gas outlet is arranged on dedusting Bottom centre's (so that gas is fully filtered by filter core) of tank body.
As a further improvement, the air inlet, the caliber of gas outlet all (cause air flow through dedusting tank not less than DN80 It is more smooth).
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention uses automatic dust-removing structure, can clear up absorption automatically using hairbrush in filter during plant running The impurity such as the oxide powder dust on core, make it come off and are deposited on tank base;The present invention can adjust filter core by electrical control Rotating speed can adjust filter core cleaning effect;The present invention is provided with two dust removal ports in tank body lower end, when bottom oxide accumulation is serious When, the impurity such as the oxide powder dust that is deposited on tank base can be cleared up;The present invention needs in filter core failure or hairbrush failure During replacement, cover can be upgraded, and be outwarded winding using tank lid lifting mechanism, so as to change filter core, greatlyd save whole The time that individual device is removed and installed, save artificial.
The stove of crystal pulling one relative to existing single crystal growing furnace dust arrester needs to carry out a dismounting and cleaning, and the present invention can reach The dismounting and cleaning of progress of crystal pulling more than ten times, saves the time before crystal pulling, while when also having easy to operate, operation Between long, efficiency of dust collection is high, cleaning is convenient, reduce artificial advantage, improve crystal pulling efficiency.
