Description
Technical field
The utility model relates to a kind of concentration and crystallization device, a kind of concentration and crystallization device device particularly in a kind of ammonium dihydrogen phosphate (ADP) production.
Background technology
Crystallization Separation is an important procedure during manufacture level ammonium dihydrogen phosphate (ADP) is produced, generally first ammonium dihydrogen phosphate (ADP) reaction slurry is concentrated at inspissator, after the concentration that reaches capacity, be transported to again in crystallizer and carry out crystallisation by cooling, after in crystallizer, magma meets the requirements of finite concentration, be transported to centrifuge again and carry out Separation of Solid and Liquid, the ammonium dihydrogen phosphate crystal obtained, then by becoming final products after drying system evaporating water.In the prior art, be generally directly connected by the pipeline of a band valve from inspissator to crystallizer, inspissator is to the connecting line of crystallizer often because of pipeline slip Crystallization Plugging, slip can not normally be carried, need cleaning of stopping, time-consuming, affect device capbility and normally play.
Summary of the invention
For above-mentioned technical problem, the utility model object goes out a kind of convenient concentration and crystallization device observed and clear up through experimental study, is applied in normal production, when there is Crystallization Plugging in pipeline, can by artificial cleaning in time, avoiding device stops, and impact is normal produces, and technical scheme is as follows:
A kind of concentration and crystallization device, form primarily of inspissator 1 and crystallizer 6, inspissator is provided with enriching slurry outlet 2, crystallizer is provided with enriching slurry entrance 7, magma outlet 8, inspissator 1 is made up of two sections of different pipelines of design with the connecting line of crystallizer 6, the pipeline 3 be connected with inspissator is provided with control valve 4, the pipeline be connected with crystallizer is the chute 9 of a upper opening, chute one end is fixedly mounted on the top cover of crystallizer 6 by device for fixing chute 10, be connected with crystallizer 6 by enriching slurry entrance 7, the other end reaches the below of the pipeline outlet 5 be connected with inspissator, chute and crystallizer shape are at a tilt angle, slip is facilitated automatically to flow in crystallizer, it is characterized in that, pipeline does not spatially directly contact with chute.
Above-mentioned a kind of concentration and crystallization device, the pipeline installing be wherein connected with inspissator 1 has heat-insulation layer.
Above-mentioned a kind of concentration and crystallization device, pipeline outlet 5 end be wherein connected with inspissator reaches crystallizer slurry inlet oblique upper, makes chute 9 size shorter.
Technical solution of the present invention beneficial effect, pass through practical application, because inspissator does not directly contact with the connecting line of crystallizer, even if the slip in chute occurs crystalline polamer once in a while, the pipeline also Crystallization Plugging be connected with inspissator also can not be caused, on the other hand, because chute pipe top is opening, once there is crystalline polamer, operating personnel can find immediately, and easy cleaning, thus avoid cleaning phenomenon generation of stopping.
The pipeline installing be connected with inspissator has heat-insulation layer, is reduced in the probability that course of conveying causes material to block at pipe intercrystalline because of pipeline radiating and cooling further.
Accompanying drawing explanation
Fig. 1 is concentration and crystallization device structural representation.
In fig. 1, wherein 1. inspissators, 2. enriching slurry outlet, the pipeline be 3. connected with inspissator, 4. control valve, the pipeline outlet be 5. connected with inspissator, 6. crystallizer, 7. enriching slurry entrance, 8. magma outlet, 9. chute, 10. device for fixing chute.
Detailed description of the invention
Embodiment 1
A kind of concentration and crystallization device, form primarily of primarily of inspissator 1 and crystallizer 6, inspissator 1 is provided with enriching slurry outlet 2, crystallizer 6 is provided with enriching slurry entrance 7, magma outlet 8, inspissator 1 is made up of two sections of different pipelines of design with the connecting line of crystallizer 6, the pipeline 3 be connected with inspissator 1 is provided with control valve 4, the pipeline be connected with crystallizer is the chute 9 of a upper opening, chute 9 one end is fixedly mounted on by device for fixing chute 10 on the top cover of crystallizer 6, be connected with crystallizer by enriching slurry entrance 7, the other end reaches the below of the pipeline outlet 5 be connected with inspissator, chute 9 and crystallizer 6 shape are at a tilt angle, slip is facilitated automatically to flow in crystallizer 6, pipeline 3 does not spatially directly contact with chute 9.
During work, enriching slurry is transported to the chute 9 of upper opening by the pipeline 3 being provided with control valve 4 from enriching slurry outlet 2, slip flows into crystallisation by cooling in crystallizer 6 from chute 9, discharges, carry out follow-up centrifugation and dry packing system after magma reaches finite concentration from magma outlet.When there being magma to jump to chute in crystallizer, when making chute slip occur crystalline polamer, magma can be cleared up in crystallization tank by instant cleaning tool by operating personnel, avoids the phenomenon of whole feed-line Crystallization Plugging.
