Special discharging device belongs to manufacturing field of equipment.
Background technique
Selenium is a kind of important semiconductor 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
0.05~0.09mg/kg, 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 nature
In metal sulfide.The main source of selenium is the byproduct generated when heavy metal sulphide ore is smelted, and the anode mud of copper electroplating and copper
The smelting smoke dust of sulphide ore produces selenium amount and accounts for about the 90% of selenium total output, remaining from lead, cobalt, nickel refining output calcining with
And it is recycled 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
The technique that skill and pyrogenic process-wet process combine.Selenium is purified using smelting equipment in pyrogenic process deselenization technique, due to selenium thermal conductivity
It is high at pitch shape, viscosity after difference, fusing, it causes blowing difficult, is usually taken and discharges above smelting equipment.Selenium smelting equipment
Usually operated under the conditions of having pressure.If taking the mode to discharge above stock melting device, since selenium is oxidizable under high temperature, out
A large amount of selenium steams can be generated when material, operating environment is poor, and manually discharge large labor intensity, is unfavorable for realizing continuous production.
Summary of the invention
In view of this, present patent application is high for viscosity after above-mentioned fusing, poor thermal conductivity, the selenium material for being not easy 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 invention adopts the following technical scheme: a kind of dedicated discharging dress of selenium vacuum smelting equipment
It sets including discharge nozzle (1), locating rack (2), discharging closure plate (3), cooling device (4) and handle (5), wherein the one of discharge nozzle (1)
End directly connects with the discharge port of selenium vacuum smelting equipment, and locating rack (2) is by being socketed in outside discharge nozzle (1) other end tube wall
The other end exit of discharge nozzle (1) is blocked in side, discharging closure plate (3) after connecting by locating rack (2)；Discharge closure plate (3) plate
Edge department is tapered, circle tapered slope side (31) of the tapered discharging closure plate (3) in edge, tapered slope side (31) and discharging
There is an in fact clearance distance S between pipe (1) exit inner wall, discharging closure plate (3) is connected to handle (5) on one side, and handle (5) passes through
Turning on or off for discharging closure plate (3) is realized in the connection of locating rack (2)；Discharging closure plate (3) lateral surface close to handle (5)
Equipped with cooling device (4), cooling device (4) is to carry out cooling work to discharging closure plate (3) outer surface.
Discharge closure plate (3) and discharge nozzle (1) coaxially, and discharging closure plate (3) can cover discharge nozzle (1) inner wall edge, institute
Clearance distance S is stated in 1mm~4mm range.
Discharge nozzle (1) outer wall wraps up one layer of heating element, wraps up thermal insulation material outside heating element again.
There are the materials that an angle β, cooling device and discharging closure plate use thermal conductivity strong to be made for tapered slope (31).
Preferably, cooling device (4) and discharging closure plate (3) are all made of copper metal material.
The inside of cooling device (4) is in hollow structure, and hollow structure top is provided with water outlet, lower part is provided with water inlet, cold
But device (4) can be passed through coolant and be cooled down.
Cooling device (4) uses recirculated water for coolant.
Handle (5) can realize that handle operates the open and close of discharging closure plate by screw rod, screw rod or pneumatic actuation mode.
Working 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, become liquid at 220 DEG C.After liquid selenium fusing, plastic state can be kept for a long time.It is molten to melt selenium
If liquid can form amorphous glass state selenium using rapid cooling；If selenium solution uses slow cooling mode, or is quickly cooled down
At again being between 100~200 DEG C after glassy state selenium, the gray selenium with certain fusing point just will form, gray selenium is brittle.
For the present invention using selenium melt under condition of fast cooling, selenium melt will form and (become) unbodied glassy state selenium,
And the feature that unbodied glassy state selenium material is high in pitch shape, viscosity, the softening temperature of this glassy state selenium is low, Ji Nengyong
It is used in vacuum sealing, and is conducive to blowing.The present invention is by being arranged cooling device (4) close to discharging closure plate (3) lateral surface, when molten
When the selenium solution melted is flow at discharging closure plate gap S, cooled device (4) rapidly cool 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).
Cooling selenium carries out heat exchange at selenium solution and discharging closure plate (3) in discharge nozzle (1), forms certain thickness nothing
Shaping selenium itself can using glassy state selenium at a temperature of this since unbodied glassy state selenium begins to soften at 40 DEG C~50 DEG C
Plasticity carries out " self-sealing ".When smelting equipment operation, discharging closure plate (3) is closed, open cooling device (4) and is remained operational straight
It stops operation to equipment, there are a fixed gap S for discharging closure plate (3) and discharge nozzle (1) contact surface, selenium melt flow after fusing
It when entering gap between the closure plate that discharges (3) and discharge nozzle (1), is cooled rapidly to form unformed glassy state selenium, glassy state selenium is certainly
It so allows discharge nozzle and discharging closure plate to be tightly connected, guarantees that discharging device outlet is air tight.
The selenium melt of discharge nozzle (1) front end constantly transfers heat to glassy state selenium at discharging closure plate (3), and cooling device
(4) constantly the selenium at discharging closure plate (3) 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, to keep the leakproofness of entire discharging device.
When smelting equipment needs to discharge, discharging closure plate (3) is opened, opens the heating device of discharge nozzle (1) leading portion setting
It is heated, is gradually melted the glassy state selenium liquid of discharge nozzle front end by the heat transfer of storeroom, the selenium melt in equipment
Naturally it flows out.
The present invention has the advantage that: using the property sealed discharging closure plate of smelting equipment processing material, and discharging, solves
The problem of high viscosity of having determined selenium material emptying difficulty, frees operator from the operation manually to discharge；The present invention, which discharges, to be filled
It is simple to set structure, easily operated and maintenance；Manufacturing cost is low.
