Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is by-pass filtration tank mounting structure schematic diagram in embodiment illustrated in fig. 1.

Specific embodiment

The utility model is described in further detail with attached drawing with reference to embodiments.

It mainly include quenching bath 1, heat exchanger 2 and quenching oil referring to figs. 1 to quenching oil cyclic utilization system shown in Fig. 2 Storage pool 3 is sequentially connected between three by pipeline, and quenching bath 1 is in a relatively high position, is quenching on pipeline The outlet end and liquid feeding end in pond 1 are respectively equipped with tapping valve 63 and liquid feed valve 64, and outlet end is located at quenching bath 1 close to the position of bottom It sets, and its liquid feeding end is equipped with close to the top of quenching bath 1, while on the pipeline also between quenching oil storage pool 3 and quenching bath 1 Elevator pump 8, in this way when opening tapping valve 63, the quenching oil in quenching bath 1 can then be entered in heat exchanger 2 by pipeline, by changing Enter in quenching oil storage pool 3 after heat is cooling, it, then can be by quenching oil storage pool after starting elevator pump 8 when opening liquid feed valve 64 The quenching oil of proper temperature is sent into quenching bath 1 in 3, suitable of course for the quenching oil temperature for ensuring to enter, and can quenched Thermometer 30 or other temperature sensing devices are arranged in oily storage pool 3, avoid for the excessively high quenching oil of temperature being sent into quenching bath 1.

It is damaged to prevent the hard sundries of bulky grain from entering in heat exchanger 2 or elevator pump 8 in the application, therefore A Rose Box 4 and filter 5 are successively arranged on pipeline between heat exchanger 2 and quenching bath 1, as shown, heat exchanger 2 with quench Pipeline between fiery pond 1 has one section and is vertically arranged, that is, has a vertical section 60, a Rose Box 4 is then arranged to be erected herein On straight section 60, a Rose Box 4 mainly includes the shell 43 for being substantially in hollow columnar, and the upper and lower ends of shell 43 are equipped with and manage The connected auxiliary section of line, radially direction is equipped with iron core 40 in shell 43, in position of the surface of this iron core 40 in the middle part of it It sets and is wound with coil 41, the both ends of coil 41 are sealed through the side wall for going out shell 43, and through position using connector, are being pacified When dress, the both ends of coil 41 are respectively connected to the positive and negative polarities of power supply 9 after going out, and switch 90 is arranged on circuit, erect The lower end opening of straight section 60 is arranged, and is equipped with dump valve 61 in the position close to its lower end, in this way when switch 90 is closed, The energization of coil 41 forms electromagnet, and the magnetic field of 40 end of iron core is most strong, can fully absorb the bulky grain being mingled in quenching oil Metal debris, and when switch 90 disconnects, and when dump valve 61 is opened, coil 41 is powered off, and magnetic field disappears, and adsorbs online Metal debris on circle 41 and iron core 40 then falls from the lower end of vertical section 60 naturally under the effect of gravity and is discharged, the present embodiment In, it for that metal debris can be uniformly processed, avoids polluting the environment, guarantees that workplace is clean, therefore in vertical section 60 are arranged right below recycling bins 7, and the metal debris being adsorbed so then can directly be fallen into recycling bins 7, are conveniently uniformly processed, also Reduce labor intensity.

In actual use, avoid coil 41 be used for a long time, surface insulation layer there is a situation where degenerating generation, therefore The position that coil 41 is corresponded on iron core 40 is arranged with protective cover 42, and thin-walled plastic cement socket pipe can be used in protective cover 42, has good Good is logical magnetic, and seal approach is carried out between protective cover 42 and iron core 40, can avoid quenching oil in this way to coil 41 It directly washes away, to be conducive to extend its service life and functional reliability.

Secondly, do not have magnetizability in view of being likely present some nonmetallic inclusions in quenching oil, it cannot be by level-one mistake The processing of filter box 4, therefore filter 5 is provided with also between vertical section 60 and heat exchanger 2, filter 5 is using conventional screen mesh type mistake Filter, and be mutually connected between filter 5 and vertical section 60 by branch pipe 62, as shown, branch pipe 62 is horizontally disposed, but branch pipe 62 lower wall is tilted down towards 60 side of vertical section, and the impurity of such bulky grain is easy to connect in branch pipe 62 and vertical section 60 Place's sedimentation is connect, is stacked into the lower end of vertical section 60 downwards, it is notable that dump valve 61 is located at branch pipe 62 and vertical section 60 connects The lower section at place is connect, accordingly even when there is the impurity of bulky grain to enter after filter 5, is also easy to glide after filtering, it can be effective Extend the service life of filter 5, or extend its maintenance period, reduces labor intensity.

To have prevented contamination precipitation in quenching bath 1 in the present embodiment, quenching quality is impacted, therefore by quenching bath 1 Inner bottom wall bevel structure is set, inclined-plane it is whole towards 63 institute of tapping valve at one end diagonally downward, similarly, the shell of by-pass filtration case 4 The design of 43 lower end of body is funnel-shaped, equally avoids impurity to be formed in by-pass filtration case 4 in this way and accumulates, especially when coil 41 powers off Afterwards, metal debris can quickly be fallen downwards, without being trapped in shell 43.

In addition, heat exchanger 2 uses water-cooled radiator in the present embodiment, and multiple change is uniformly distributed on the surface of radiator 2 Hot fin 20 can further improve the cooling heat transferring efficiency of heat exchanger 2 in this way, it is ensured that quenching oil can be subtracted with quick cyclic utilization Few waiting time, improve quenching efficiency.

With reference to Fig. 1 and Fig. 2, this system in use, when quenching bath 1 complete primary quenching after, closure switch 90, when coil 41, which are powered, forms electromagnet, and dump valve 61 and liquid feed valve 64 are in closed state, then open tapping valve 63, then quenching oil one It is secondary to be entered back into after the filtration of by-pass filtration case 4 and filter 5 in heat exchanger 2, it cools down into heat exchange, then flows into again In quenching oil storage pool 3, after determining that the quenching oil in quenching bath 1 flows out, then tapping valve 63 is closed, then opens discharge Valve 61 finally disconnects switch 90, is adsorbed on coil 41 or metal debris on iron core 40 in this way or is deposited in vertical section 60 Other large granular impurities then naturally fall enter recycling bins 7 in, facilitate and be uniformly processed, when observe do not fall impurity it Afterwards, that is, dump valve 61 is closed.

Finally, can be beaten by the temperature that thermometer 30 observes quenching oil in quenching oil storage pool 3 if temperature is suitable Liquid feed valve 64 is opened, quenching oil storage pool 3 is sent into quenching bath 1 by elevator pump 8, that is, can proceed with quenching technical operation.

Finally, it should be noted that foregoing description is only the preferred embodiment of the utility model, the ordinary skill of this field Personnel are under the enlightenment of the utility model, under the premise of without prejudice to the utility model aims and claim, can make more Kind is similar to be indicated, such transformation is each fallen within the protection scope of the utility model.
