Abstract
The invention discloses a desilicator discharge device used in the production process of aluminum oxide. A barrel body (1) is provided with an upper sealing head (9) and a conical sealing head (5), and a steam pipe (3) and a discharge pipe (8) are fixed in the barrel body (1) respectively through a pipe clamp (2). The upper end of the barrel body (1) penetrates out of the upper sealing head (9), while the lower end is positioned on the lower part of the conical sealing head (5), wherein the steam pipe (3) is divided into two branch pipes at the lower end, and outlets of the branch pipes face to the corresponding circumference direction of the conical sealing head (5); a material inlet pipe (7) is arranged in a hole at the bottom of the conical sealing head (5), a spray head (6) is arranged on the material inlet pipe (7), and the spray head (6) is provided with spray holes which are counter holes; and flanges are welded on the material inlet pipe (7) and the spray head (6). The desilicator discharge device has the advantages of simple structure and convenient operation. Silicon dregs do not form scale formation on the inner wall of the device and can be discharged in time.
Description
Technical field
The present invention relates to prevent in a kind of desiliconization device the drawing mechanism of white residue accumulation.
Background technology
The desiliconization device is to utilize steam liquefaction liberated heat to add thermal material in aluminum oxide production process, and material is stayed for some time within it, follows pressure and hot conditions generation chemical reaction, separates out white residue, reaches the purpose of desiliconization.When material is no longer separated out white residue by the time, material is discharged enter next process again.The white residue of separating out on desiliconization device bottom interior wall, causes fouling because density is deposited on desiliconization device bottom than material senior general, and easy-clear does not cause very big harm to equipment.In existing desiliconization device, also there is not the drawing mechanism that can prevent effectively that white residue from piling up on desiliconization device bottom interior wall.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of discharging device of desiliconisation device is provided, and this device can in time be discharged white residue, easy to operate and white residue can not form fouling on the equipment inwall, to overcome the deficiencies in the prior art.
The present invention constitutes like this: it comprises cylindrical shell 1, upper cover 9, conical head 5 are arranged on cylindrical shell 1, vapour pipe 3, discharge nozzle 8 are fixed in the cylindrical shell 1 by pipe clamp 2 respectively, its upper end passes upper cover 9, the lower end bottom at conical head 5, its middle steam tube 3 is divided into two arms in the lower end, the outlet of arm is towards the corresponding circumferential direction of conical head 5; Feed-pipe 7 is arranged in the base apertures of conical head 5, shower nozzle 6 is arranged on feed-pipe 7, on shower nozzle 6, spray orifice is arranged.
Spray orifice on the shower nozzle 6 is a counter sink, and this structure can guarantee that the material under certain pressure sprays radially and enter in the desiliconization device, and can sedimentary white residue be blown afloat maximum area.
On feed-pipe 7, shower nozzle 6, be welded with flange respectively.
During work, material sprays radially under certain pressure and enters in the desiliconization device, and can sedimentary white residue be blown afloat maximum area; Steam enters desiliconization device internal heating material from vapour pipe.Because the shape of vapour pipe arm and the guide functions of conical head, steam is after flowing out the vapour pipe arm, itself has just possessed tangential initial velocity, and the flow direction of the inwall meeting time changing steam of conical head is along the circumferential direction formation vapour stream of conical head.Steam can blow material is made equal state in the bottom of conical head rotation simultaneously at mobile, white residue also can be along with material keeps same rotating state together, and no longer be deposited on bottom the conical head, by the time material stops time enough when silicon is deviate from fully in the desiliconization device, and the white residue of bottom is discharged from discharge nozzle together in company with material and entered the lower next process of pressure.
Compared with prior art, the present invention is simple in structure, and is easy to operate, and white residue does not form fouling on the equipment inwall, and can in time discharge white residue.

Embodiment
Embodiments of the invention: this device is made up of cylindrical shell 1, pipe clamp 2, vapour pipe 3, bearing 4, conical head 5, shower nozzle 6, feed-pipe 7, discharge nozzle 8, upper cover 9 etc.Vapour pipe 3, discharge nozzle 8 are fixed in the cylindrical shell 1 by pipe clamp 2 respectively, and its upper end passes the bottom that upper cover 9, lower end are arranged in conical head 5, and its middle steam tube 3 is divided into two arms in the lower end, and the outlet of arm is towards the corresponding circumferential direction of conical head 5; Feed-pipe 7 is arranged in the base apertures of conical head 5, shower nozzle 6 is arranged on feed-pipe 7.During making, feed-pipe 7 joins the two together respectively with after the flange welding with shower nozzle 6 again, has numerous counter sinks on the shower nozzle 6.
Claims (2)
