Abstract
A serum material mixer is provided, which relates to a device for mixing fluid material in the process of metallurgy chemical engineering, in particular to a high and low temperature material mixing device for the mash and lye while stripping in producing hydrafil and alumina. The basic structure of the mixer is a T-shaped three-way steel work, which is characterized in that: a material flow guide cone object is arranged in the mixer, the bottom of guide cone object is placed in the middle and on the wall of two through material serum flow and material liquid flow feeding tube, the conical surface of the guide cone object to the opening the feeding tube is an arc surface on the feeding tube with the surface tangent to the surface of the feeding tube; the radian of the arc surface is same to that of an arc at the cross of the level feeding tube and the mixing output tube. A material guide awl is arranged in the mixer, which can make the tangential of the material cross and enter into a stripping machine after full mixing, the vortex won't happen and reduces abrasion, suction and shake. The invention solves the problem that two material flows has different content, different temperature and are easy to cause shaking when contacting, and three material at medium temperature after mixing and at high and low temperature causes welding interface breakage and crossing and pre-aerating.
Description
Technical field
A kind of mixer of serum materials, the ore pulp when relating to the device of fluid-mixing material in a kind of metallurgy chemical process, particularly Bayer process and producing aluminium hydroxide, aluminium oxide stripping and the high temperature of alkali lye, the device that low-temperature material mixes.
Technical background
In metallurgy chemical process, often need be with two kinds of variable concentrations, the fluid at differing temperatures material mixes.At the high pressure dissolving-out process of alumina producing Bayer process, often that active ingredient in bauxite and the stripping ore is required whole alkali lye grind into qualified ore pulp, after batching, with high-pressure pump through preheater (heater) feeding digester.Scab owing to separate out in pulp pre-heating and the heating process in leaching, production process is had a negative impact, further process modification adopts a small amount of alkali lye and first ore mixer mill to make the high concentration ore pulp, then high concentration ore pulp and stripping must all the other alkali lye feed digester with high-pressure pump through preheater separately respectively, with the purpose that reaches energy-conservation, raises the efficiency.
In existing patent application, a kind of threeway tubular type blender is disclosed, two kinds of logistics enter from two relative charging mouths of pipe, crash after the interchange, and confluxing enters into the discharging opening vertical with two charging apertures.Owing in producing, adopt alkali liquid temperature height (200～285 ℃), during with the ore pulp (100～200 ℃) of low temperature, two plume material composition difference are big, the temperature difference big, produce vibration during contact; Mixing of materials is inhomogeneous, and is big to device damage, and discharging opening is fragile, and the mission life-span is still shorter.
Summary of the invention
The present invention is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can solve effectively that the vibration that two plume material composition difference are big, the temperature difference big, batch mixing produces is big to device damage, the mixer of serum materials of mixing of materials problem of non-uniform.
Purpose of the present invention is achieved through the following technical solutions.
A kind of mixer of serum materials, the basic structure of its blender is " fourth " font threeway steelwork, three terminations at the blender three-way pipe are the connector that has flange, and two straight pipe horizontal positioned of the subtend of blender, are respectively pulp flow and feed liquid stream feed pipe; Vertical with two straight pipes is the feed liquid stream and the mixed discharge nozzle of pulp flow of blender; It is characterized in that in blender, being provided with material flow guiding cone, its guiding cone awl is centrally placed at end on two the straight-through pulp flows and feed liquid stream feed pipe upper tube wall of subtend, the guiding cone conical surface to the conical surface of the charging mouth of pipe be one with feed pipe on the tangent cambered surface of pipe face; Its cambered surface radian is identical with the cambered surface radian that mixes the discharge nozzle intersection with the horizontal feed pipe.
Mixer of serum materials of the present invention is rational in infrastructure, be center line, be provided with material guiding awl in logical inside with three three-way pipe joints, enter in the digester after can making material tangentially cross, fully mix, do not produce eddy current, reduced wearing and tearing, cavitation and the vibrations of material tube wall.Have characteristics such as simple in structure, that maintenance is few, operating cost is low.Can make the alkali lye (200～285 ℃) of high temperature even, safe, mix efficiently with the ore pulp (100～200 ℃) of low temperature.

Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of mixer of serum materials, the basic structure of its blender is " fourth " font threeway steelwork, three terminations at the blender three-way pipe are the connector that has flange, and two straight pipe horizontal positioned of the subtend of blender, are respectively pulp flow 1 and feed liquid and flow 2 feed pipes; Vertical with two straight pipes is the feed liquid stream and the mixed discharge nozzle 3 of pulp flow of blender; It is characterized in that in blender, being provided with material flow guiding cone 4, its guiding cone awl is centrally placed at end on two the straight-through pulp flows and feed liquid stream feed pipe upper tube wall of subtend, the guiding cone conical surface to the conical surface of the charging mouth of pipe be one with feed pipe on the tangent cambered surface of pipe face; Its cambered surface radian is identical with the cambered surface radian that mixes the discharge nozzle intersection with the horizontal feed pipe.
During use, high temperature alkaline solution is connected with blender alkali lye head piece by flange by the alkali lye conveyance conduit, flow of slurry connects with blender ore pulp head piece by flange by the ore pulp conveyance conduit, dash mutually and converge the batch mixing process of finishing in the blender subtend under pressure, enter digester by the discharging opening outflow, finish the crossing of flow of slurry, fully mix, mixing efficiency height, rational in infrastructure can not cause the cavitation of equipment of digester and the vibrations of digester.Have characteristics such as simple in structure, that maintenance is few, operating cost is low.Solve that two plume material composition difference are big, the temperature difference is big, easily produce after vibration and high temperature, low temperature and the mixing three kinds of materials of moderate temperature during contact institute's connecting pipe equipment is produced thermal stress causes crossing of soldering opening cracking to give mixed problem.
