Detailed description of the invention
The detailed description of the invention of the present invention is given, for the present invention is described further below with reference to accompanying drawing.
Embodiment 1
The super micron mill liquid nitrogen chiller of the present embodiment, mainly includes liquid nitrogen container 1, liquid nitrogen pump 7, vacuum insulated piping 8, water bath type vaporizer 9, rustless steel tank for coolant 13, coolant pump 19, coolant 21, electric-control system 22.
During work, should first check for liquid nitrogen container liquidometer 2 and liquid nitrogen container Pressure gauge 5 is the most normal, liquid nitrogen inlet manually-operated gate 4 and sewage draining exit manually-operated gate 15 should be at closed mode.It is first turned on liquid nitrogen container manually-operated gate 6, switch on power and press electrical control button 22-1 and start system, liquid nitrogen pump 7 starts to start operating, liquid nitrogen is flowed in water bath type vaporizer 9 by liquid nitrogen container 1 by vacuum insulated piping 8, in water bath type vaporizer 9, nitrogen gasification heat absorption, is become gaseous state from liquid, makes the temperature around water bath type vaporizer 9 be greatly reduced, and carry out heat exchange with coolant 21, so that coolant 21 temperature reduces.Nitrogen after gasification rises to nitrogen gas outlet 12 through the pipeline of water bath type vaporizer 9 and enters in air.Along with the continuous gasification of nitrogen, the temperature of coolant 21 gradually reduces, and temperature signal is sent in PLC system 22-3 by temperature sensor 10, and shows in real time on touch screen 22-2.When coolant 21 temperature will arrive design temperature, PLC system 22-3 can automatically control liquid nitrogen pump converter 22-4 makes liquid nitrogen pump 7 rotating speed decline, and reduces liquid nitrogen injection rate, until temperature reaches design temperature and is automatically stopped.
After PLC system 22-3 receives the run signal of super micron mill, coolant pump 19 can start automatically, coolant 21 is driven to lead to super micron mill cooler pan 20 by coolant circulation line 17, after super micron mill cooler pan 20 is cooled down by coolant 21, rustless steel tank for coolant 13 can be flowed back to along coolant circulation line 17.When the actual temperature of coolant 21 and design temperature have deviation, pid algorithm in PLC system 22-3 can calculate liquid nitrogen pump 7 and the rotating speed of coolant pump 19 that suitable system is run automatically, and send corresponding rotational speed regulation respectively and instruct to liquid nitrogen pump frequency conversion device 22-4 and coolant pump converter 22-5, the chilling temperature and the cooling effect that make whole super micron mill chiller keep stable, when super micron mill is out of service, PLC system 22-3 can control coolant pump 19 and be automatically stopped operation.
When chiller is stopped using, should first press electrical control button 22-1 and shut down, after liquid nitrogen pump 7 and coolant pump 19 all quit work, turn off power supply, finally close liquid nitrogen container manually-operated gate 6.
The super micron mill liquid nitrogen chiller of embodiment have following a little:
1, nontoxic due to nitrogen and will not explode, therefore security reliability is high；
2, floor space is little, without fixing water source or cistern, can be suitably used for the needs of various landform and weather；
3, using liquid nitrogen is cold-producing medium, using subzero 75 degree of non-icing low temperature conduction oils is coolant, by brand-new design and control method, obtain the stable minimum coolant up to subzero 70 degree, again by coolant as cooling medium, to lower the temperature to super micron mill, the temperature of super micron mill crushing rear material can be reduced greatly, in the case of not destroying its nutritional labeling, improve the smashing fineness of material.Expand the range of application of super micron mill, there is the highest practical commercial value.
