Abstract
The utility model discloses a kind of refrigerating unit of normalizing furnace, comprise cooling room, work support, temperature-detecting device, pressure-detecting device is provided with in described cooling room, blower fan is installed at the top of described cooling room, described cooling room is provided with blast inlet, air outlet, and described blast inlet is by intake stack connecting fan, and described intake stack is provided with variable valve, described air outlet connects vacuum fan by wind pipe, and described wind pipe is provided with variable valve two.The beneficial effects of the utility model are: the utility model, by installing vacuum fan, blower fan and variable valve and variable valve two on cooling room, can be bled, stablize the pressure in cooling room, meet process requirements while air inlet.
Description
Technical field
The utility model relates to technical field of heat treatment, is specifically related to a kind of refrigerating unit of normalizing furnace.
Background technology
The refrigerating unit of existing isothermal normalizing furnace is general, and most what adopt is deliver in cooling room by workpiece by conveying belt, then directly blows to workpiece the effect reaching cooling with blower fan, and then enters down one manufacturing procedure.Though this traditional method of cooling can realize, but in whole process of cooling, cold wind directly blows on workpiece, cause work-piece cools excessive velocities, affect workpiece mechanical property, meanwhile, the upper and lower temperature difference of workpiece compared with ambassador through heat treated workpiece hardness scattered error, have a strong impact in quality product, restriction enterprise development.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of refrigerating unit of normalizing furnace, by determining that increasing gas in cooling room still bleeds at cooling indoor location temperature-detecting device, pressure-detecting device.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the refrigerating unit providing a kind of normalizing furnace, comprise cooling room, work support, temperature-detecting device, pressure-detecting device is provided with in described cooling room, blower fan is installed at the top of described cooling room, described cooling room is provided with blast inlet, air outlet, described blast inlet is by intake stack connecting fan, described intake stack is provided with variable valve, described air outlet connects vacuum fan by wind pipe, and described wind pipe is provided with variable valve two.
In a preferred embodiment of the present utility model, in described cooling room, go back provided with fan.
The beneficial effects of the utility model are: the utility model by installing vacuum fan, blower fan and variable valve and variable valve two on cooling room, can bleed while air inlet, stablize the pressure in cooling room, meet process requirements, in addition by provided with fan in cooling room, further acceleration gas flow, improves cooling performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, cooling room, 2, temperature-detecting device, 3, vacuum fan, 4, variable valve two, 5, wind pipe, 6, pressure-detecting device, 7, intake stack, 8, variable valve, 9, blower fan, 10, fan.
Embodiment
Below in conjunction with embodiment, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of refrigerating unit of normalizing furnace, comprise cooling room, be provided with work support, temperature-detecting device, pressure-detecting device in described cooling room, blower fan is installed at the top of described cooling room, and described cooling room is provided with blast inlet, air outlet, described blast inlet is by intake stack connecting fan, described intake stack is provided with variable valve, and described air outlet connects vacuum fan by wind pipe, and described wind pipe is provided with variable valve two.
Blower fan is first dried in stove, and when pressure-detecting device detects that furnace inner gas pressure is excessive, vacuum fan is started working, and according to pressure value adjustment variable valve, changes the intake velocity of blower fan and the speed of evacuation of vacuum fan.
The beneficial effects of the utility model are: the utility model, by installing vacuum fan, blower fan and variable valve and variable valve two on cooling room, can be bled, stablize the pressure in cooling room, meet process requirements while air inlet.
For a person skilled in the art; still can the technical scheme described in foregoing embodiments be modified; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. the refrigerating unit of a normalizing furnace, it is characterized in that: comprise cooling room, work support, temperature-detecting device, pressure-detecting device is provided with in described cooling room, blower fan is installed at the top of described cooling room, described cooling room is provided with blast inlet, air outlet, and described blast inlet is by intake stack connecting fan, and described intake stack is provided with variable valve, described air outlet connects vacuum fan by wind pipe, and described wind pipe is provided with variable valve two.
