Abstract
The invention discloses a heat energy recycling system of quenching oil, comprising a front washing region, a quenching furnace region, a quenching oil region, and an tempering furnace region which are arranged from front to back in sequence; the front washing region, the quenching furnace region, the quenching oil region and the tempering furnace region are internally provided with mesh belts for conveying workpieces. The heat recycling system of the quenching oil is characterized in that the front washing region is internally provided with a flowing pipeline; two sides of the quenching oil region are respectively provided with an oil drainage pipeline and an oil feeding pipeline; one end of the flowing pipeline in the front washing region is in through connection with the oil drainage pipeline and the other end of the flowing pipeline is in through connection with the oil feeding pipeline; and the oil drainage pipeline is provided with a valve for controlling the lockage of the oil drainage pipeline. The invention solves the problems that the cooling water absorbs the heat energy of the quenching oil in the prior art and then is drained, and the heat energy is wasted; and the provided heat recycling system of the quenching oil conveys the heat energy of the quenching oil to the front washing system again for utilization.
Description
Technical field
The present invention relates to a kind of modifying device of thermal treatment process, particularly relate to a kind of quenching oil heat energy recycle system.
Background technology
Metal works is heated to a certain proper temperature and keeps for some time, immerse in the quenching media refrigerative metal heat treatmet technology fast immediately.Quenching media commonly used has salt solution, water, MO, air etc.Quenching can improve the hardness and the wear resistance of metal works, thereby is widely used in various workers, mould, measurer and requires the part (like gear, roll, carburized parts etc.) of surface abrasion resistance.The purpose of quenching is to make supercooled austenite carry out martensite or bainite transformation; Obtain martensite or bainite structure; Cooperate tempering then with differing temps; With intensity, hardness, wear resistance, fatigue strength and the toughness etc. that significantly improve steel, thereby satisfy the different request for utilizations of various mechanical component and instrument.
But before workpiece quenches, remove cold deformation and add man-hour attached to grease on the workpiece surface and dirt, gasoline commonly used, acetone, oil of bananas etc. are wiped examination, also can be soaked in the basic soln with certain temperature.In quenching process; Need workpiece be put into quenching media (quenching oil) cools off; The temperature of quenching oil will raise like this, need come Cooling Quenching oil so that quenching oil can continue to use through water coolant, all be cooled water absorption and draining of the heat energy of quenching oil like this.This method has caused the loss in vain of heat energy, and needs the special cooling apparatus of configuration, and equipment cost is high.
Summary of the invention
Absorb and drain in order to solve in the prior art quenching oil heat energy water that is cooled, the problem of waste heat energy the invention provides a kind of quenching oil heat energy recycle system, and the heat energy of quenching oil is transported to front wash system utilization once more.
In order to achieve the above object, the technical scheme that the present invention taked is:
A kind of quenching oil heat energy recycle system; The front wash area, quenching furnance district, quenching oil district, the tempering stove district that are provided with before and after comprising successively; Be provided with the guipure of conveying workpieces in said front wash area, quenching furnance district, quenching oil district, the tempering stove district, it is characterized in that: in the front wash area, be provided with circulation duct, be respectively arranged with oil-drain pipe and inflow pipeline in the both sides in quenching oil district; An end of circulation duct connects with oil-drain pipe and is connected in the said front wash area, and the other end connects with inflow pipeline and is connected.
Aforesaid a kind of quenching oil heat energy recycle system, it is characterized in that: oil-drain pipe is provided with the valve that the control oil-drain pipe opens and closes.
Aforesaid a kind of quenching oil heat energy recycle system, it is characterized in that: the quenching oil district is provided with the oil groove thermostat.
The invention has the beneficial effects as follows: quenching oil heat energy recycle of the present invention system; The heat energy of quenching oil is incorporated in the front wash area, has both realized that quenching oil carries out cooling purpose, effectively utilized the heat energy of quenching oil simultaneously again; Practice thrift the electric heating cost, reduced waste.Need not in addition independent cooling apparatus is set, reduced equipment cost.
Description of drawings
Fig. 1 is a quenching oil heat energy recycle system architecture synoptic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
As shown in Figure 1, a kind of quenching oil heat energy recycle system, the front wash area 1, quenching furnance district 2, quenching oil district 3, the tempering stove district 4 that are provided with before and after comprising successively.Be provided with the guipure of conveying workpieces in said front wash area 1, quenching furnance district 2, quenching oil district 3, the tempering stove district 4; In front wash area 1, be provided with circulation duct; Be respectively arranged with oil-drain pipe 5 and inflow pipeline 6 in the both sides in quenching oil district 3; One end of the circulation duct in the front wash area 1 connects with oil-drain pipe 5 and is connected, and the other end connects with inflow pipeline 6 and is connected.Said quenching oil district 3, oil-drain pipe 5, circulation duct, inflow pipeline 6 are formed a flow cycle.Oil-drain pipe 5 is provided with the valve 7 that control oil-drain pipe 5 opens and closes.Quenching oil district 3 is provided with oil groove thermostat 8, and oil groove thermostat 8 is used for showing and controlling the temperature in quenching oil district 3.
Introduce the working process of quenching oil heat energy recycle system down below
Open three-way valve when 1, the quenching oil temperature arrives 60 ℃ quenching oil is transported to through oil-drain pipe 5 in the circulation duct of front wash area 1, carry out cold and hot exchange with front wash area 1 interior preceding dilution and reach energy-saving effect.
The quenching oil that 2, will finish heat exchange is transported in the quenching oil district 3 through inflow pipeline 6, proceeds quenching technology.
Show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
