Abstract
The utility model discloses a solution stirring device of an itaconic acid bleaching tank, which belongs to the field of liquid stirring and is used for solving the problems of mechanical stirring for bleaching. The solution stirring device comprises a bleaching tank body which is provided with a feed port and a discharge port. The solution stirring device is characterized in that the bottom of the tank body is provided with an air distributing pipe which is connected with an air compressor through an air inlet pipe, and the tank body is also provided with an exhaust port. Air at a high speed is dispersed in solutions in an air bubble form, and the density of one solution is reduced on one side of ventilation while the density of another solution is high on one side of stuffiness, so that a density difference is generated between the solutions on the ventilation side and the stuffiness side, and the solutions circulate in the bleaching tank to form a similar stirring effect. The solution stirring device has a simpler structure compared with equipment for mechanical stirring, is low in energy consumption and shortens bleaching time, and the use ratio of the solution stirring device is improved.
Description
Technical field
The utility model relates to a kind of liquid stirring device, and methylene-succinic acid bleacher solution stirring device particularly is used for the decolouring step of obtained by producing itaconic acid by fermentation.
Background technology
Generally adopt at present obtained by producing itaconic acid by fermentation both at home and abroad, it mainly comprises fermentation culture, obtain itaconic acid fermentation liquid, itaconic acid fermentation liquid is through ion-exchange, activated carbon decolorizing obtains the methylene-succinic acid cleaner liquid, methylene-succinic acid filtering night is through evaporation concentration, and crystallization, the step such as centrifugal obtain the methylene-succinic acid crystal.
The decolouring step of obtained by producing itaconic acid by fermentation, what adopt at present is generally to carry out in the mechanical stirring bleacher.This alr mode power consumption is higher, and easily forms the dead angle, is unfavorable for feed liquid and decolouring the contacting of thing, thereby affect decolorizing effect, the prolongation bleaching time.
The utility model content
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of methylene-succinic acid bleacher solution stirring device is provided, and this device can make the material contact evenly rapidly, saves bleaching time.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
A kind of methylene-succinic acid bleacher solution stirring device, comprise the bleacher tank body, described tank body is provided with opening for feed and discharge port, it is characterized in that: be provided with a wind-distributing pipe in the bottom of tank body, described wind-distributing pipe connects air compressor by inlet pipe, also is provided with venting port on tank body.
Further program of the utility model can also be:
Described wind-distributing pipe is a ring pipe, and the above is provided with air outlet.
The beneficial effects of the utility model are:
Due to the external air compressor of inlet pipe, open the inlet pipe valve during operation, pressurized air evenly enters bottom bleacher along wind-distributing pipe, because air velocity is high, be dispersed in liquid with bubble form, in a side of ventilation, fluid density descends, in an airproof side, fluid density is larger, thereby produce density difference with the liquid of ventilation side, thus form the circulation of decolouring pot liquid, form and stir similar effects, but it is obviously simple that device structure stirs than mechanical type, consume energy low, shortened bleaching time, increased plant factor.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1 tank body, 2 opening for feeds, 3 venting ports, 4 discharge ports, 5 wind-distributing pipes, 6 inlet pipe.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
A kind of methylene-succinic acid bleacher solution stirring device, comprise bleacher tank body 1, the top of described tank body 1 is provided with opening for feed 2, the bottom is provided with a discharge port 4, be provided with a wind-distributing pipe 5 in the bottom of tank body, described wind-distributing pipe 5 connects the outer air compressor of tank bodies by inlet pipe 6, also is provided with venting port 3 on tank body top.
Described wind-distributing pipe 5 is a horizontally disposed ring pipe, and inlet pipe 6 is communicated with described wind-distributing pipe 5, and the above is provided with air outlet.
The part that the utility model does not describe in detail is prior art.
