The cooling agent gone out will be first into run-off；Work stage is additionally provided with the middle and lower part of cooling bay, the work stage is used to put
Put workpiece to be quenched；The bottom of the run-off is provided with flowline, flowline is connected to organic Rankine bottoming cycle by pump
Exchanged heat in the evaporator of heat-exchange system with cooling agent；The lower section of the evaporator has oil inlet, is connected with the pump, steams
The top of hair device has oil-out, and the oil-out is connected by flexible pipe with oil inlet pipe, and the wall of the oil inlet pipe through cooling bay is stretched
Enter the top to cooling bay, the expanding machine of organic Rankine bottoming cycle heat-exchange system is connected with the pump power, and expanding machine is connected with hair
Motor, so as to which the mechanical energy of expanding machine is converted into electric energy, transmission device is arranged with outside the generator shaft of generator and is connected with fan
Connect, the fan is used to radiate to condenser.
Further, the organic Rankine bottoming cycle heat-exchange system also includes expanding machine, condenser and circulating pump, circulating pump
Working medium by condenser condensation is transported in evaporator, is mutually changed into high temperature and high pressure gas, high temperature after being absorbed heat in evaporator
Gases at high pressure further become the gas of low-temp low-pressure in expanding machine after expansion work, finally become low pressure liquid within the condenser
Body.
Further, cooling agent enters from the top of evaporator, and enters expanding machine from the lower section of evaporator.
Beneficial effects of the present invention are：The heat sink of the cooling oil of the present invention has taken into full account the temperature layer of cooling oil
Level, can simply and rapidly be cooled down to cooling oil, and cooling effectiveness is high, and cost is low, and WHRS is simple in construction, effect
Rate is high.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, can be good at understanding that the structure of the present invention, principle, work are special with reference to following description
Point and advantage, but accompanying drawing described herein as is used for that the present invention is explained further, and accompanying schematic figure is intended merely to preferably right
The present invention illustrates, and does not form improper restriction to the present invention, wherein：
Fig. 1 is the schematic diagram of the WHRS of the quenching cooling oil of the present invention;
Fig. 2 is the organic rankine cycle system schematic diagram in Fig. 1.
Embodiment
With reference to example and accompanying drawing, the invention will be further described, it is noted that following examples are only
To be schematical, it is not intended to the limitation present invention.
Referring to Fig. 1, the heat sink of quenching cooling oil of the invention includes cooling bay 1, the exterior arrangement of cooling bay 1
There is run-off 2, when workpiece is put into cooling bay 1, the cooling agent of spilling will be first into run-off, then again from run-off
Middle extraction.
Work stage 3 is additionally provided with the middle and lower part of cooling bay, the work stage 3 is used to place workpiece to be quenched.
Flowline 4 is provided with the bottom of the run-off, flowline 4 is connected to organic Rankine bottoming cycle by pump 5 and exchanged heat
Exchanged heat in system 6 with cooling agent.The lower section of the evaporator 61 of the organic Rankine bottoming cycle heat-exchange system has oil inlet, with
Pump 5 connects, and the top of evaporator 61 of organic Rankine bottoming cycle heat-exchange system has oil-out, and the oil-out passes through flexible pipe and oil inlet pipe
7 connections, the wall of oil inlet pipe 7 through cooling bay 1 extend into the top of cooling bay 1.
Because oil-out 4 is arranged on the lower section of run-off 2, the cooling oil temperature of lower section is lower than top, can so subtract
The burden of light organic Rankine bottoming cycle heat-exchange system 6.Oil inlet 7 is arranged on the top of cooling bay, because the cooling oil after cooling is close
Bottom larger, therefore that cooling oil can be sunk to above cooling oil is spent, so that the cooling oil generation pair in cooling bay
Stream, fully heat exchange.
Cooling agent enters above the evaporator 61 of Rankine cycle heat-exchange system 6, and from the steaming of Rankine cycle heat-exchange system 6
Discharged by the extraction of cooling medium pump 8 lower section for sending out device 61.
Referring to Fig. 2, it is more clearly shown organic Rankine bottoming cycle is how to collect used heat.The organic Rankine bottoming cycle
Heat-exchange system 6 includes evaporator 61, expanding machine 63, condenser 65 and circulating pump 62.It is cold that circulating pump 62 will pass through condenser 65
Solidifying working medium is transported in evaporator 61, is mutually changed into high temperature and high pressure gas after being absorbed heat in evaporator 61, high temperature and high pressure gas enter
One step becomes the gas of low-temp low-pressure in expanding machine 63 after expansion work, finally become low pressure liquid in condenser 65.
Expanding machine 63 is connected with generator 64, so as to which the mechanical energy of expanding machine is converted into electric energy.
The other end of expanding machine 53 connects pump 5, and thus expanding machine can give pump 5 to provide power.
Transmission device is arranged with outside the generator shaft of generator 64 to be connected with fan 66, the fan 66 is used for condenser 65
Radiating.
The heat sink of the cooling oil of the present invention can simply and rapidly be cooled down to cooling oil, and cooling effectiveness is high, into
This is low.Heat recovery efficiency is high, has saved the energy.
Although be described in detail to the present invention in conjunction with the embodiments, it should be understood by those skilled in the art that
Ground is that the present invention is not limited only to specific embodiment, on the contrary, in the various amendments without departing from the application spirit and essence, is become
Shape and replacement are all fallen among the protection domain of the application.
