Description
Technical field
The seed precipitation tank uniform mixing device, belong to fine aluminum hydroxide powder crystallizer field, is specifically related to a kind of fine aluminum hydroxide powder seed and mixed uniformly seed precipitation tank uniform mixing device of sodium aluminate solution of making.
Background technology
After sodium aluminate solution is sent in seed precipitation tank, add the fine aluminum hydroxide powder seed, decomposing sodium aluminate solution is separated out fine aluminum hydroxide powder, sodium aluminate solution and the uniformity coefficient that the fine aluminum hydroxide powder seed mixes have determined the crystallization velocity of aluminium hydroxide, directly affect production efficiency, common method is by agitator, sodium aluminate solution evenly to be mixed with the fine aluminum hydroxide powder seed at present, but agitator is mainly horizontal stirring, in seed precipitation tank, vertical degree of mixing can't complete by agitator, has reduced production efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, the seed precipitation tank uniform mixing device of provide a kind of even mixing fine aluminum hydroxide powder seed and sodium aluminate solution, enhancing productivity.
The utility model solves the technical scheme that its technical problem adopts: this seed precipitation tank uniform mixing device, comprise seed precipitation tank, be provided with agitator in seed precipitation tank, it is characterized in that: be provided with vertical extraction pipe in described seed precipitation tank, the extraction pipe bottom is communicated with carries the material airduct, and the extraction pipe upper end open is positioned at seed precipitation tank.
Described extraction pipe has symmetrical four, all near the seed precipitation tank inwall, fixes.
Described extraction pipe upper end open arranged transversely, and there is downward-sloping angle.
Described extraction pipe lower ending opening is wedge shape.
Described carrying expects that airduct is stretched in seed precipitation tank by the upper end open of seed precipitation tank.
Described seed precipitation tank bottom is up big and down small taper, and the slip output channel is communicated with the lower end at seed precipitation tank.
Compared with prior art, the beneficial effect that the utility model seed precipitation tank uniform mixing device has is:
1, evenly mix, enhance productivity: by extraction pipe, the feed liquid of seed precipitation tank bottom is promoted to seed precipitation tank top, makes the vertical evenly mixing of feed liquid in seed precipitation tank, accelerate the fine aluminum hydroxide powder crystallization, and then enhance productivity;
2, in seed precipitation tank, slip mixes unanimously, and particle velocity strengthens, and is difficult for agglomeration, makes product granularity even, and granularity is thinner;
3, simple in structure, utilize extraction pipe commonly used and compressor pipeline just can realize, cost is low.
The accompanying drawing explanation
Fig. 1 is the utility model seed precipitation tank uniform mixing device structural representation.
Wherein: 1, seed precipitation tank 2, carry material airduct 3, extraction pipe 4, agitator 5, slip output channel 6, pump.
Fig. 1 is the most preferred embodiment of the utility model seed precipitation tank uniform mixing device, below in conjunction with 1 pair of the utility model of accompanying drawing, is described further.
Embodiment
With reference to accompanying drawing 1: this seed precipitation tank uniform mixing device, comprise seed precipitation tank 1 and extraction pipe 3, extraction pipe 3 has symmetrical four, vertically be fixed on the inwall place of seed precipitation tank 1, extraction pipe 3 upper end open are positioned at the upper end of seed precipitation tank 1, extraction pipe 3 lower ending openings are positioned at seed precipitation tank 1 bottom, are provided with vertical agitator 4 in seed precipitation tank 1.
The bottom of extraction pipe 3 is communicated with carries material airduct 2, carries and expects that airduct 2 is stretched in seed precipitation tank 1 by the upper end open of seed precipitation tank 1, can avoid causing sealing problem through the barrel of seed precipitation tank 1, carries material airduct 2 and can select corrosion resistant plastic hose.
The upper end open arranged transversely of extraction pipe 3, point to the central axis of seed precipitation tank 1, and have downward-sloping angle, can prevent that the feed liquid that is brought up from seed precipitation tank 1 bottom from falling along the outer wall of extraction pipe 3, mixed effect is poor, and the feed liquid that extraction pipe 3 is brought up all sprays to seed precipitation tank 1 middle part, reach better mixed effect, particle velocity strengthens, and is difficult for agglomeration, make product granularity even, granularity is thinner.The lower ending opening of extraction pipe 3 is wedge shape, is convenient to pump feed liquid.
The bottom of seed precipitation tank 1 is up big and down small taper, can make the aluminium hydroxide of crystallization focus on the bottom of taper, be convenient to collect, carry, slip output channel 5 is positioned at the lower end of seed precipitation tank 1, and be connected with pump 6, by pump 6, the extraction of the fine aluminum hydroxide powder slip of seed precipitation tank 1 conical lower portion is delivered to pressure filter (not shown in FIG.) and is filtered.
Principle of work and working process are as follows: at first sodium aluminate solution is added in seed precipitation tank 1, then add according to a certain percentage the fine aluminum hydroxide powder seed, agitator 4 starts to stir, sodium aluminate solution is evenly mixed with the fine aluminum hydroxide powder seed, after stirring certain hour, carry pressurized air by carrying material airduct 2 for extraction pipe 3, the mixture proportion of the interior feed liquid of extraction pipe 3 and air is less than extraction pipe 3 lower ending opening place feed liquid proportions, thereby generation pressure difference, extraction pipe 3 promotes and is delivered to seed precipitation tank 1 top by the feed liquid of seed precipitation tank 1 bottom, seed precipitation tank 1 bottom is evenly mixed with the feed liquid on top.
Drop on seed precipitation tank 1 bottom under after the fine aluminum hydroxide powder crystallization and form the fine aluminum hydroxide powder slip, pump 6 work, filtered fine aluminum hydroxide powder slurry pipeline transport to pressure filter (not shown in FIG.) by slip output channel 5.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
