Description
Technical field
The present invention relates to a kind of crystallizer, the invention particularly relates to a kind of crystallizer that alkali is used of making.
Background technology
The disclosed production heavy soda ash of Chinese utility model patent specification of the CN87217100 that on March 9th, 1989 authorized and its equipment body of crystallizer of monohydrated sodium carbonate are that cartridge type bottom, garden is conical tank body.Tank diameter ∮ 1200 * 2450mm, in establish guide shell, its diameter is ∮ 600mm.Be provided with flow distribution plate in the guide shell periphery, the flow distribution plate number is 4, length L=1280mm.Flow distribution plate is connected with the inboard screw that adopts of guide shell and tank body.Alr mode is a screw, and its diameter is ∮ 590mm, and screw is made up of 3-5 sheet blade, and speed of agitator is controlled by buncher that is positioned at the tank body top and reductor, and propeller blade adopts the nonmetallic plastics of coating.This crystallizer flow distribution plate easily scabs and damages and the nonmetal plastics of propeller blade coating are easily washed away by the carbon oxygen of crystallization, and these cause this crystallizer maintenance capacity big, and the production utilization of capacity is low, can not realize the requirement of continuous crystalline hydrate and automation control.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, in the damage that reduces equipment, change continuous crystalline hydrate equipment into by being interrupted the crystalline hydrate device, the adding and the taking-up of the monohydrated sodium carbonate after the crystallization that are light soda ash and saturated solution of sodium carbonate are carried out simultaneously, reach the quantity-produced purpose.
The purpose of this utility model realizes by following proposal.
The utility model is a kind of makes the crystallizer that alkali is used, comprise tank body, motor, reductor, screw, guide shell, shaft, have alkali inlet, inlet, discharging opening, thermometer mouth, gas outlet, overfall on the described tank body, it is characterized in that: it also comprises the dividing plate that has discharging opening on its that is arranged on tank body top, open two severe meter mouths and liquid level gauge mouth on tank body top, has feed opening on the described dividing plate; Described shaft passes the tank body top, and an end is arranged on the tank body rotationally; Be fixed with two on the described shaft and lay respectively at the top of described dividing plate, the screw of bottom; Described guide shell is arranged on described screw outside, and its bottom is fixed on the described dividing plate by gusset; Described tank wall is surrounded by heat exchange jacket, and its upper and lower end has delivery port, water inlet.
Crystallizer of the present utility model is because the employing dividing plate is divided into tank body two-layer up and down, be respectively arranged with screw in every layer again, make hybrid reaction stage and growth crystallization, the taking-up stage of material be divided into two stages, again because tank wall is provided with heat exchange jacket, can control the reaction temperature of crystalline hydrate, thereby realized the requirement of continuous crystalline hydrate having reached the quantity-produced purpose; And do not need to apply because this equipment has been cancelled flow distribution plate, propeller blade yet, thereby reduced the maintenance of equipment amount.
Description of drawings
Figure is the utility model structure of mould schematic diagram.
The specific embodiment
The utility model shown in the figure is a kind of makes the crystallizer that alkali is used, comprise that main body is that the garden cylindrical lower is tank body 16, motor 1, the reductor 2 that is connected with motor 1, screw 20, guide shell 21, the shaft 19 of spheroidal, have alkali inlet 3, inlet 4, discharging opening 15, thermometer mouth 5, gas outlet 14, overfall 13 on the described tank body 16, it also comprises the dividing plate 18 that has discharging opening 12 on its that is arranged on tank body top, opens severe meter mouth 7,8 and liquid level gauge mouth 6 on tank body 16 tops; Described shaft 19 passes tank body 6 tops, and an end links to each other with reductor, and the other end is arranged on the tank body 16 rotationally; Be fixed with two on the described shaft 19 and lay respectively at the top of described dividing plate 18, the screw 20 of bottom, described screw 20 is made up of 3-5 sheet blade, material is a cast steel, and described guide shell 21 is arranged on described screw 20 outsides, and its bottom is fixed on the described dividing plate 18 by gusset; Described tank body 16 outer walls are surrounded by heat exchange jacket 9, and described heat exchange jacket 9 is fixed on the described tank body 16 by gusset, and its upper and lower end has delivery port 11, water inlet 17; Described thermometer mouth 5 is one, is positioned at the middle part of described tank body 16, and described thermometer mouth 5 is preferably 3, lays respectively at the upper, middle and lower portion of described tank body 16.The below of described dividing plate 18 is provided with heat exchange coil 10, and its upside is fixed on the dividing plate 18, and described screw 20 is made up of 3-5 sheet blade, is preferably 4.Described alkali inlet 3, inlet 4 can be positioned at the top of described tank body 16, and described discharging opening 15 can be positioned on the spherical side wall of described tank body 16.
In described crystalline hydrate device, crystal exists an infall process inside and outside guide shell, when crystal reaches certain particle diameter, be deposited in tank body dividing plate top, and form certain brilliant bed, stop unreacted light ash to enter the tank body bottom, and enough big crystal enters the tank body bottom by the dividing plate feed opening, continue to grow up in the bottom, realized that mixing of materials crystallization reaction and crystalline hydrate are grown up, the taking-up segmentation is carried out, thereby realized carrying out continuously of crystalline hydrate.
