Special discharging device, belongs to manufacturing field of equipment.
Background technology
Selenium is a kind of important semi-conducting material, and fusing point is 221 DEG C, and boiling point is 685 DEG C.Abundance of the selenium in the earth's crust be only
It is not yet found that the independent Se fractionation of economic value, the usual association of selenium is in copper, lead, nickel etc. in 0.05~0.09mg/kg, nature
In metal sulfide.The main source of selenium is the byproduct produced when heavy metal sulphide ore is smelted, and the anode mud of copper electroplating and copper
Sulphide ore smelting smoke dust production selenium amount account for the 90% of selenium total output, remaining come from lead, cobalt, nickel refining output calcining with
And reclaimed in the sour mud of gas washing in SA production and the washing mud of production slurrying.
The method for extracting selenium from the anode mud of copper electroplating both at home and abroad is broadly divided into Whote-wet method deselenization technique, thermal process work
Skill, and the technique that pyrogenic process-wet method is combined.Selenium is purified using smelting equipment in pyrogenic process deselenization technique, due to selenium thermal conductivity
It is high into pitch shape, viscosity after difference, fusing, cause blowing difficult, be usually taken and discharged above smelting equipment.Selenium smelting equipment
Usually operated under the conditions of having pressure.If taking the mode of the discharging above stock melting device, because selenium is oxidizable under high temperature, go out
A large amount of selenium steams can be produced during material, operating environment is poor, artificial discharging labor intensity is big, is unfavorable for realizing continuous production.
The content of the invention
In view of this, present patent application is directed to viscosity height, poor thermal conductivity after above-mentioned fusing, and the selenium material for being difficult blowing is provided
A kind of selenium vacuum smelting equipment Special discharging device, to solve such material emptying difficult problem.
In order to achieve the above object, the present invention uses following technical scheme：A kind of special discharging dress of selenium vacuum smelting equipment
Putting includes the one of discharge nozzle (1), locating rack (2), discharging closure plate (3), cooling device (4) and handle (5), wherein discharge nozzle (1)
End directly connects with the discharging opening of selenium vacuum smelting equipment, and locating rack (2) is by being socketed in outside discharge nozzle (1) other end tube wall

Operation principle of the present invention：Selenium can form amorphous and crystalline solid.Amorphous selenium is also " liquid " selenium, can be divided into
Powdery selenium, vitreous selenium and gluey selenium, the fusing point that amorphous selenium is not fixed.Amorphous selenium begins to soft at 40 DEG C~50 DEG C
Change, can be flowed at 100 DEG C, liquid is become at 220 DEG C.After liquid selenium fusing, plastic state can be kept for a long time.Melt selenium molten
If liquid can form amorphous glass state selenium using quick cooling；If selenium solution uses Slow cooling mode, or quick cooling
It again is at after into glassy state selenium between 100~200 DEG C, the gray selenium with certain fusing point will be formed, gray selenium is brittle.
The present invention is using selenium melt under condition of fast cooling, and selenium melt can form and (become) unbodied glassy state selenium,
And unbodied glassy state selenium material in pitch shape, viscosity is high the characteristics of, the softening temperature of this glassy state selenium is low, Ji Nengyong
Used in vacuum sealing, blowing is beneficial to again.The present invention close to discharging closure plate (3) lateral surface by setting cooling device (4), when molten
When the selenium solution melted is flow at discharging closure plate gap S, cooled device (4) rapidly cools to form unbodied glassy state selenium,
Gap location can be full of amorphous glass state selenium between discharging closure plate (3) and discharge nozzle (1), and amorphous glass state selenium is conceded naturally
Expect that gap is in air-tight state between closure plate (3) and discharge nozzle (1).
Selenium solution and the selenium of discharging closure plate (3) place cooling in discharge nozzle (1) carry out heat exchange, form certain thickness nothing
Shape selenium, itself can using glassy state selenium at a temperature of this because unbodied glassy state selenium begins to softening at 40 DEG C~50 DEG C
Plasticity carries out " self sealss ".When smelting equipment is run, discharging closure plate (3) is closed, cooling device (4) is opened and remains on straight
Stopped operation to equipment, discharging closure plate (3) and discharge nozzle (1) contact surface leaves a fixed gap S, selenium melt flow after fusing
When entering space between the closure plate that discharges (3) and discharge nozzle (1), it is cooled rapidly to form unformed glassy state selenium, glassy state selenium is certainly
Discharge nozzle and discharging closure plate is so allowed to be tightly connected, it is ensured that drawing mechanism outlet is air tight.
The selenium melt of discharge nozzle (1) front end constantly transfers heat to discharging closure plate (3) place glassy state selenium, and cooling device
(4) constantly the selenium at closure plate (3) place that discharges is cooled down, by constantly conducting heat and cooling down, keeps discharge nozzle (1) and discharging stifled
The selenium melt of plate (3) gap is glassy state, so as to keep the sealing of whole drawing mechanism.
When smelting equipment needs discharging, discharging closure plate (3) is opened, the heater that discharge nozzle (1) leading portion is set is opened
Heated, gradually melted the glassy state selenium liquid of discharge nozzle front end by the heat transfer of storeroom, the selenium liquation in equipment
Naturally flow out.
The present invention has the advantage that：The property sealed discharging closure plate of material is handled using smelting equipment, and is discharged, is solved
The problem of high viscosity of having determined selenium material emptying is difficult, makes operating personnel be freed from the operation manually discharged；Present invention discharging dress
Put simple in construction, it is easy to operation and maintenance；Manufacturing cost is low.
