Abstract
The utility model discloses a cooling system of a vacuum double-chamber oil gas glowing furnace. The cooling system of the vacuum double-chamber oil gas glowing furnace comprises a shell body, a guide system and a heat exchange device. The heat exchange device is mainly heat exchanger. The heat exchanger is arranged in the inner side of a wall of the shell body. The guide system comprises a high pressure fan, an impeller and an air flue. The high pressure fan is arranged at the top of the shell body in an overhead mode, the impeller is arranged on the end portion of a rotating shaft of the high pressure fan and extends in a cavity body of the shell body and the cavity body of the shell body forms the air flue. The cooling system of the vacuum double-chamber oil gas glowing furnace is characterized in that a plurality of heat exchangers are distributed on the periphery of an inner wall of the shell body, an air guide flow system is distributed on the periphery of an inner wall of the bottom of the shell body and the air guide flow system is located on the lower portion of a workpiece which is in the cavity body. Due to the fact that heat exchange amount of the heat exchanger is increased, the high pressure air cool forms high flow speed heat exchange along the periphery of the inner wall of the shell body, cooling speed of the cavity body is greatly improved and hardenability of the workpiece can be beneficially achieved. The role of the air guide flow system which is arranged at the bottom of the cavity body enables the air to flow from the bottom of the workpiece to the workpiece and the air guide flow system is distributed along the periphery of the bottom of the cavity body, so the cooling uniformity of the workpiece is guaranteed.
Description
Technical field
The utility model relates to a kind of vacuum dual-chamber oil gas quenching furnance cooling system, especially a kind of vacuum dual-chamber oil gas quenching furnance cooling system of workpiece quenching good cooling results.
Background technology
Present domestic double-chamber vacuum oil-quenching air-cooling stove is mainly horizontal double-chamber structure, mainly is comprised of parts such as heating chamber, oil quenching chamber, air-cooling apparatus, vacuum heat-insulation gate, workpiece transfer mechanism, oily stirring systems.In the routine use process, the problem that present equipment exists is that the smaller air cooling effect that causes of fan design is bad, the mode that directly blow at the top is adopted in the air channel in addition, place the workpiece bottom of cavity basically to be subjected to cooling less than cooling air, be that whole wind cooling zone temperature distribution is very inhomogeneous, so that the effect of work-piece cools is undesirable.
The utility model content
Technical problem to be solved in the utility model provides a kind of vacuum oven convection heating system, and workpiece is placed in one, homogeneous heating, and efficient is high.
Technical problem to be solved in the utility model provides a kind of vacuum dual-chamber oil gas quenching furnance cooling system, has the characteristics of good cooling results.
For solving upper letter in reply technical problem, the technical solution of the utility model is: a kind of vacuum dual-chamber oil gas quenching furnance cooling system, comprise housing, flow guide system and heat-exchanger rig, heat-exchanger rig is mainly interchanger, interchanger is arranged at the housing wall inboard, flow guide system comprises high pressure positive blower, impeller and air channel, described high pressure positive blower up-set type is arranged at case top, described impeller is arranged at the high pressure positive blower end part of driving shaft and stretches in the shell cavity, described shell cavity consists of the air channel, and its innovative point is: be distributed with some interchanger around the described inner walls; Be distributed with the wind flow guide system around the described housing bottom inwall, described wind flow guide system is positioned at the below of cavity workpiece.
The utility model has the advantage of: by increasing the heat of interchanger, around inner walls, form the high flow rate heat exchange so that high pressure is air-cooled, so that the cavity speed of cooling improves greatly, be conducive to realize the hardening capacity of workpiece, and the effect of the wind flow guide system of cavity bottom, so that wind blows to workpiece from the bottom of workpiece, and the wind guiding systems distributes around cavity bottom, thereby guaranteed the work-piece cools homogeneity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the front view of a kind of vacuum dual-chamber oil gas of the utility model quenching furnance cooling system.
Fig. 2 is the vertical view of a kind of vacuum dual-chamber oil gas of the utility model quenching furnance cooling system.
Embodiment
A kind of vacuum dual-chamber oil gas quenching furnance cooling system illustrated in figures 1 and 2 comprises housing 1, flow guide system and heat-exchanger rig 3.Heat-exchanger rig 3 is mainly interchanger, and it is inboard that interchanger is arranged at housing 1 wall; Flow guide system comprises high pressure positive blower 4, impeller 5 and air channel 6, and high pressure positive blower 4 up-set types are arranged at housing 1 top, and impeller 5 is arranged at high pressure positive blower 4 end part of driving shafts and stretches in the shell cavity 7, and shell cavity 7 consists of air channel 6.For improving the cooling performance of workpiece, be distributed with some interchanger around housing 1 inwall; Be distributed with wind flow guide system 8 around housing 1 bottom interior wall, and be positioned at the below of cavity 7 workpiece 9.
During specific works, because wind flow guide system 8 is installed in the bottom of interchanger, and around housing, distribute, thereby the flow direction of wind is had guide effect.Wind is realized fast cooling through interchanger on the one hand, on the other hand through the cooling of housing 1 inwall, the wind-engaging that makes the workpiece in the cavity evenly and speed of cooling greatly improve.
