At present, domestic reactive crystallization device single jar of batch production of little volume crystallizer that adopt more, volume of equipment is little, adds batch operation, and the charging discharging is lost time, and energy consumption is high, production is unstable.Its occupation area of equipment is big, and production can't realize automatic control, waste resource and labour, and the boric acid product granularity that obtains is little, and impurity is many, and is of poor quality, and production cost is high.
The utility model content
The utility model technical problem to be solved provides a kind of simple in structure, energy consumption is low, crystallization effect is good acidification reaction mold of producing boric acid.
For addressing the above problem, the described acidification reaction mold of producing boric acid of the utility model, it is characterized in that: this mold comprises speed reduction unit, half a coupler, main shaft, frame and housing; The top of said housing is provided with cover plate, sets gradually guide shell, following guide shell, blade, deflection cone in it from the top down, and its bottom one side is provided with discharge port, and the opposite side of its bottom then is provided with sewage draining exit; Be respectively equipped with opening for feed, said frame on the said cover plate, its center links together said upward guide shell, following guide shell, blade through said main shaft; The top of said main shaft links to each other with said speed reduction unit through said half a coupler.
Said housing is the vertical barrel type container.
Said go up guide shell, down guide shell, blade, deflection cone medullary ray all with the central lines of said main shaft.
The said guide shell of going up links to each other with said frame.
Be provided with said blade in the said down guide shell, and with the bottom connection of said housing.
Also be provided with manhole and metering orifice on the said cover plate.
Said frame is provided with ventilation opening.
The utility model compared with prior art has the following advantages:
1, because the utility model adopts the structure formation of guide shell up and down, therefore, realized that reaction and crystallization carry out simultaneously, improved production efficiency.
2, be provided with down guide shell, blade, deflection cone in the utility model crystallizing field; And under their comprehensive action; The circular flow and the turbulent velocity that the disperse phase refinement are dispersed in reach higher in the mold; Improved mass transfer velocity, crystal grain is grown up evenly simultaneously, and product granularity reaches the quality standard of import boric acid.
3, the utility model is simple in structure, and energy consumption is low, is applicable to the reactive crystallization of various Chemical Manufacture.Be applied in the Qinghai East Platform produces per year in the Industrialization Projects of 2500 tons of boric acid at present.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-speed reduction unit 2-half a coupler 3-main shaft 4-frame 5-goes up guide shell 7-blade 8-cover plate 9-housing 10-deflection cone 11-opening for feed 12-discharge port 13-sewage draining exit under the guide shell 6-.
Embodiment
As shown in Figure 1, produce the acidification reaction mold of boric acid, this mold comprises speed reduction unit 1, half a coupler 2, main shaft 3, frame 4 and housing 9.Housing 9 is the vertical barrel type container.
The top of housing 9 is provided with cover plate 8, sets gradually guide shell 5, following guide shell 6, blade 7, deflection cone 10 in it from the top down, and its bottom one side is provided with discharge port 12, and the opposite side of its bottom then is provided with sewage draining exit 13; Be respectively equipped with opening for feed 11, frame 4 on the cover plate 8, its center will go up guide shell 5, descend guide shell 6, blade 7 to link together through main shaft 3; The top of main shaft 3 links to each other with speed reduction unit 1 through half a coupler 2.
Wherein: go up guide shell 5, down guide shell 6, blade 7, deflection cone 10 medullary ray all with the central lines of main shaft 3; Last guide shell 5 links to each other with frame 4; Be provided with blade 7 in the following guide shell 6, and with the bottom connection of housing 9; Also be provided with manhole and metering orifice on the cover plate 8; Frame 4 is provided with ventilation opening.
Going up guide shell in the utility model is reaction zone, and multiple feeding liquid tentatively mixes, reacts at this; Following guide shell is a crystallizing field, and feed liquid is reacted in this completion, crystallization, and through internal recycle, prolongs the residence time, makes the boric acid crystal grain big and even; Blade is pusher stirring rake, and the control rotating speed is 62r/min, makes it can provide enough big circular flow to mix with solid-liquid system in the realization equipment; Deflection cone distributes crystalline particle once more, and small-particle promotes up once more and circulates, and has prolonged the particulate residence time, makes that particle continues to grow up.
During work, various materials are put in the guide shell 5 through opening for feed 11, carry out preliminary mixing, reaction after, be transferred to down in the guide shell 6, under the effect of blade 7 and deflection cone 8, the completion internal recycle obtains uniform particles, boric acid crystal that granularity is bigger.
