Abstract
The utility model discloses a fast air cooling system of a vacuum gas quenching furnace. The system comprises an air cooling motor, a heat exchanger and a furnace body heating chamber, wherein a centrifugal impeller and a wind shield are arranged on a transmission shaft of the air cooling motor; and the air cooling motor is arranged at the outer part of the furnace body heating chamber. The system is characterized in that the wind shield is welded with the inner wall of the furnace body to form a closed cavity; multiple wind pipes are distributed around the furnace wall along the extension direction of the furnace body; the end parts of the wind pipes on the same side are welded with the wind shield; multiple nozzles are distributed on the wind pipe along the extension direction; the nozzles are vertical to the central axis of the furnace body; the heat exchanger is arranged in the cavity of the furnace body heating chamber close to the wind shield; the heat exchanger is a multi-layer annular heat exchanger and is mainly formed by welding multiple copper pipes with a toothed blade; and the copper pipes are connected with each other in parallel and connected with a water inlet tank and a water outlet tank outside. By arranging multiple nozzles directly facing to a workpiece on multiple wind pipes around the furnace wall, the wind outlet quantity is increased, and the cooling speed is increased.
Description
Technical field
The utility model relates to a kind of vacuum air-quenching furnace fast wind cooling system, the vacuum air-quenching furnace accelerate cooling system that especially a kind of energy consumption is low, speed of cooling is fast.
Background technology
The general method of cooling of vacuum heat treatment equipment of at present China's production generally is to adopt the mode that strengthens cooling blower and increase inflation pressure to realize the quick cooling that stove is interior.The power of the high-pressure gas quenching furnace high pressure positive blower of present 500kg is at 132kw, and external blower fan only has about 45kw, and from the energy consumption angle, the air-quenching furnace power of fan consuming electric power of China will be higher than external twice.And from the inflation angle, inflation pressure is larger in the stove, the amount of inert gas that consumes is also just more, can improve speed of cooling although it is so, but the gas consumption conference causes production cost to increase, and owing to the increasing of furnace pressure, the dynamics that ventilated machine moves under high pressure conditions also need strengthen in addition, so power of motor also must strengthen, and causes energy expenditure.
The utility model content
Technical problem to be solved in the utility model provides a kind of vacuum air-quenching furnace fast wind cooling system, and energy consumption is low and speed of cooling is fast.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum air-quenching furnace fast wind cooling system, comprise ventilated machine, interchanger and body of heater heating chamber, be provided with centrifugal impeller and windsheild on the described ventilated machine transmission shaft, it is outside that described ventilated machine is arranged at the body of heater heating chamber, its innovative point is: described centrifugal impeller and windsheild are arranged in the body of heater heating chamber cavity, and described windsheild and inboard wall of furnace body welding form the enclosed cavity; Be distributed with some airducts along the body of heater bearing of trend around the described furnace wall, described end, some airducts the same side and windsheild welding, described airduct is along being distributed with some nozzles on its bearing of trend, described nozzle is perpendicular to the body of heater central axis, and described workpiece places in the body of heater heating chamber cavity; Described interchanger is arranged at slightly near in the body of heater heating chamber cavity of windsheild, and described interchanger is the circular heat exchanger of multilayered structure, mainly be welded by some copper pipes and gear piece, parallel with one anotherly between the described copper pipe link to each other with water tank with the inlet chest of peripheral hardware.
The utility model has the advantage of: by interchanger, impeller and windsheild are arranged in the body of heater, and around in the furnace wall, some airducts are set, and at the airduct bearing of trend some nozzles over against workpiece are set, and increased air output, improved speed of cooling; In addition by being the multi-layer annular interchanger with design of heat exchanger, and so that the copper pipe in the circular heat exchanger assembly is in parallel and link to each other with water tank with external inlet chest, thereby improve heat transfer effect by the flow that changes the water by body, thus the raising heat transfer effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of vacuum air-quenching furnace fast wind of the utility model cooling system.
Embodiment
A kind of vacuum air-quenching furnace fast wind cooling system shown in Figure 1 mainly is comprised of ventilated machine 1, impeller 2, windsheild 3, airduct 4, nozzle 5, circular heat exchanger 6.Described ventilated machine 1 turns for rotating speed 2800/two-stage electric motor of min, impeller 2 on its transmission shaft adopts centrifugal impeller, the windsheild 3 of end part of driving shaft and inboard wall of furnace body welding form enclosed cavity configuration 7, enclosed cavity configuration 7 is provided with some airducts 4 along the furnace wall bearing of trend, and end, airduct the same side and windsheild 3 welding, thereby the small space of airduct 4 and windsheild 3 and twere forms air channel 9.For improving the speed of cooling of workpiece, along being welded with some nozzles 5 on airduct 4 bearing of trends, and the direct subtend workpiece of the air-out direction of nozzle 5, workpiece places enclosed cavity configuration 7, because the outlet of air quantity is uniform all around along body of heater, so that air-out uniformity, thereby and the large assurance of air quantity work-piece cools speed quickening.Interchanger adopts the circular heat exchanger of multilayered structure in addition, be arranged in the body of heater heating chamber cavity, mainly be welded by some copper pipes and gear piece, and the parallel with one another and external inlet chest of plumbers shed and water tank, the flow of the water that passes through by change improves the heat transfer effect of interchanger.
