Abstract
Alkali stove is endured in a kind of anti-explosion, be arranged at there is thermal source roasting kiln above, it comprises the taper the bottom of a pan of top closure, circular furnace wall and U-shaped foundation ring; This taper the bottom of a pan has conical surface, and the bottom periphery of this conical surface is connected with the bottom periphery of this circular furnace wall by this U-shaped foundation ring, and the bottom of this circular furnace wall is provided with discharge nozzle.So, due to the setting in the taper the bottom of a pan, enduring in sodium hydroxide lye process, the sodium hydroxide crystal of separating out with the increase of naoh concentration can be slipped in U-shaped foundation ring along the conical surface in the taper the bottom of a pan, because U-shaped foundation ring is away from the thermal source of roasting kiln, U-shaped foundation ring is heated relatively weak, can not thermal explosion be produced, therefore, originally enduring alkali stove, more existing to endure alkali stove safer.
Description
Technical field
The utility model relates to plumbous antimony nonferrous smelting industry, is specifically related to one and endures alkali stove, more particularly, relate to a kind of produce local implosion when preventing from enduring alkali endure alkali stove.
Background technology
Plumbous antimony nonferrous smelting industry, when utilization Harris process alloy thick with the refining of molten sodium hydroxide method, often can use and endure alkali stove, be boiled into the melting alkali lye of 300-400 DEG C to reuse after a large amount of sodium hydroxide lyes is concentrated.
In the process, along with the increase of naoh concentration, the sodium hydroxide crystal of separating out is sunken to the bottom of a pan in a large number, be plane or in slightly arcuation owing to enduring the bottom of a pan in alkali stove, the sodium hydroxide crystal being deposited on the bottom of a pan is made too to concentrate on roasting kiln thermal source place, cause heat conduction bad, form local implosion, the sodium hydroxide lye sputtered works the mischief to the people of surrounding or thing.
In view of existing above-mentioned disappearance of enduring alkali stove, pole haves much room for improvement.
Utility model content
Technical problem to be solved in the utility model is: for above-mentioned deficiency of the prior art, provides a kind of anti-explosion preventing from enduring generation local implosion in alkali process to endure alkali stove.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: alkali stove is endured in a kind of anti-explosion, be arranged at there is thermal source roasting kiln above, be characterized in, it comprises the taper the bottom of a pan of top closure, circular furnace wall and U-shaped foundation ring; This taper the bottom of a pan has conical surface, and the bottom periphery of this conical surface is connected with the bottom periphery of this circular furnace wall by this U-shaped foundation ring, and the bottom of this circular furnace wall is provided with discharge nozzle.
Periphery, described circular furnace wall is provided with circular outer wall above discharge nozzle.
Thermal insulation layer is provided with between described circular furnace wall and this circular outer wall.Described thermal insulation layer is made up of perlite powder or aluminium silicate wool.
Described discharge nozzle is provided with bleeder valve.
So, due to the setting in the taper the bottom of a pan, enduring in sodium hydroxide lye process, the sodium hydroxide crystal of separating out with the increase of naoh concentration can be slipped in U-shaped foundation ring along the conical surface in the taper the bottom of a pan, because U-shaped foundation ring is away from the thermal source of roasting kiln, U-shaped foundation ring is heated relatively weak, can not thermal explosion be produced, therefore, originally enduring alkali stove, more existing to endure alkali stove safer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utility model is that alkali stove is endured in a kind of anti-explosion, be arranged at there is thermal source A1 roasting kiln A above, it comprises the taper the bottom of a pan 1, circular furnace wall 2 and U-shaped foundation ring 3.
The top closure in this taper the bottom of a pan 1, and there is conical surface 11, the bottom periphery of this conical surface 11 is connected by the bottom periphery of the circular furnace wall 2 of this U-shaped foundation ring 3 and this.This periphery, circular furnace wall 2 is provided with thermal insulation layer 4, and this thermal insulation layer 4 periphery is provided with circular outer wall 5.And the bottom of this circular furnace wall 2 is provided with discharge nozzle 6, this discharge nozzle 6 is provided with bleeder valve 7 to regulate the discharging flow of melting alkali lye.
Above-mentioned thermal insulation layer 4 is made up of perlite powder or aluminium silicate wool etc.
So, in enduring in sodium hydroxide lye process, the sodium hydroxide crystal of separating out with the increase of naoh concentration can be slipped in U-shaped foundation ring 3 along the conical surface 11 in the taper the bottom of a pan 1, because U-shaped foundation ring 3 is away from the thermal source A1 of roasting kiln A, U-shaped foundation ring 3 is heated relatively weak, thermal explosion can not be produced, and the sodium hydroxide lye of melting deposits above the U-shaped foundation ring 3 of crystal and is discharged by discharge nozzle 6 in this.
