According to the invention, the cooling efficiency is high, the crystallization effect is good, and the cooling uniformity and crystallization uniformity of materials are improved.
Description
Technical field
The present invention relates to a kind of crystallization kettle, particularly relate to a kind of pyrrole ketone crystallization kettle.
Background technology
Pymetrozine belongs to pyridines or Triazinone pesticide, is brand-new non-killing livestock property pesticide, is developed the earliest by Ciba-Geigy company of Switzerland in 1988, and the sucking pest of this product to various crop shows excellent prevention effect.Pymetrozine has action of contace poison to insect, also has systemic activity simultaneously.Need to use crystallization kettle to carry out crystallization in the manufacture of pyrrole ketone.
Crystallization kettle is after mixing of materials reaction, the crystallizer that still domestic demand chilled water or chilled water are sharply lowered the temperature.Existing crystallization kettle structure is comparatively complicated, is substantially all to use chuck to cool, and jacket for heat exchange area is little, and fluid-flow rate is little, and heat transfer coefficient is not high, thus it is uneven to cause material to be lowered the temperature, thus affects crystal habit.
In view of the defect existed in above prior art, be necessary it to improve further, make it have more standby practicality, could realistic service condition.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of pyrrole ketone crystallization kettle.
The present invention takes following technical scheme to realize: a kind of pyrrole ketone crystallization kettle, comprise kettle and be arranged on the feed pipe at two ends, kettle left and right, discharge nozzle, material coil pipe is connected with between described feed pipe and discharge nozzle, described material coil pipe is bending is arranged in described kettle inside, the inner lowermost end of described kettle is provided with cool brine water inlet pipe, the other end of described cool brine outlet pipe is connected to cool brine case, the other end of described cool brine case is connected to cool brine outlet pipe by cool brine circulation pipe, described cool brine outlet pipe is arranged on the most significant end of described kettle inside, the side outer wall of described kettle is provided with observation window, the top of described kettle is provided with thermometer, the afterbody of described thermometer is inserted into kettle inside.
Concrete, described cool brine case inside is provided with water pump.Described feed pipe, discharge nozzle are equipped with valve.Described cool brine water inlet pipe and cool brine outlet pipe are equipped with valve.
The present invention has following beneficial effect in sum: the present invention is easy to use, and cooling effectiveness is high, and crystallization effect is good, improves lowering temperature uniform degree and the crystallization uniformity of material; Coordinated with the multiple of cool brine circulation pipe by cool brine outlet pipe, cool brine water inlet pipe, make cool brine in the cooling of kettle Inner eycle, reach good cooling effect; The observation window arranged is convenient to observe crystallization progress at any time; Cooling medium adopts cool brine, and cooling effect is good, and crystalline rate is faster; By adopting material disc tubular construction, the contact area that material can be made to be cooled is large, good cooling results; The thermometer arranged can observe the temperature of kettle inside at any time, is conducive to the temperature of crystallization control.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, thermometer; 2, observation window; 3, feed pipe; 4, kettle; 5, material coil pipe; 6, cool brine outlet pipe; 7, discharge nozzle; 8, cool brine circulation pipe; 9, cool brine case; 10, water pump; 11, cool brine water inlet pipe.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
As shown in Figure 1, the present invention takes following technical scheme to realize: a kind of pyrrole ketone crystallization kettle, comprise kettle 4 and be arranged on feed pipe 3, the discharge nozzle 7 at kettle about 4 two ends, be connected with material coil pipe 5 between described feed pipe 3 and discharge nozzle 7, described material coil pipe 5 is bending is arranged in described kettle 4 inside.
As preferred version of the present invention, the inner lowermost end of kettle 4 of the present invention is provided with cool brine water inlet pipe 11, the other end of described cool brine outlet pipe 11 is connected to cool brine case 9, the other end of described cool brine case 9 is connected to cool brine outlet pipe 6 by cool brine circulation pipe 8, described cool brine outlet pipe 6 is arranged on the most significant end of described kettle 4 inside, and described cool brine case 9 inside is provided with water pump 10.Coordinated with the multiple of cool brine circulation pipe 8 by cool brine outlet pipe 6, cool brine water inlet pipe 11, make cool brine in the cooling of kettle 4 Inner eycle, both using water wisely, again can circulating cooling, kills two birds with one stone; Wherein, water pump 10 can export endlessly cool brine and play dynamic action, meanwhile, cool brine can be transmitted back to cool brine case 9 again, in whole circulating cooling process, play dynamic action.
As preferred version of the present invention, the side outer wall of kettle 4 of the present invention is provided with observation window 2, the convenient progress of observing response at any time.
As preferred version of the present invention, the top of kettle 4 of the present invention is provided with thermometer 1, and the afterbody of described thermometer 1 is inserted into kettle 4 inside, can observe the temperature of kettle 4 inside at any time, be conducive to the temperature of crystallization control.
As preferred version of the present invention, feed pipe 3 of the present invention, discharge nozzle 7 are equipped with valve, convenient according to reaction process switch feed pipe 3, discharge nozzle 7 at any time.
As preferred version of the present invention, cool brine water inlet pipe 11 of the present invention and cool brine outlet pipe 6 are equipped with valve, convenient according to reaction process cool brine water inlet pipe 11 and cool brine outlet pipe 6 at any time.
The above is embodiments of the invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
