Abstract
The invention 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 present invention 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 that at present China produces is generally to adopt the mode that strengthens cooling blower and increase inflation pressure to realize cooling fast in stove.The power of the high-pressure gas quenching furnace high pressure positive blower of current 500kg is at 132kw, and external blower fan only has 45kw left and right, and from energy consumption angle, the air-quenching furnace power of fan consuming electric power of China will be higher than external twice.And from inflation angle, in stove, inflation pressure is larger, the amount of inert gas consuming is also just more, can improve speed of cooling although it is so, but gas consumption conference causes production cost to increase, due to the increasing of furnace pressure, the dynamics that ventilated machine moves under high pressure conditions also needs to strengthen in addition, so power of motor also must strengthen, and causes energy expenditure.
Summary of the invention
Technical problem to be solved by this invention is to provide 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, technical scheme of the present invention is: a kind of vacuum air-quenching furnace fast wind cooling system, comprise ventilated machine, interchanger and body of heater heating chamber, on described ventilated machine transmission shaft, be provided with centrifugal impeller and windsheild, it is outside that described ventilated machine is arranged at body of heater heating chamber, its innovative point is: described centrifugal impeller and windsheild are arranged in body of heater heating chamber cavity, and described windsheild and inboard wall of furnace body welding form enclosed cavity; Described furnace wall surrounding is distributed with some airducts along body of heater bearing of trend, described end, some airducts the same side and windsheild welding, described airduct is along being distributed with some nozzles on its bearing of trend, and described nozzle is perpendicular to body of heater central axis, and described workpiece is placed in body of heater heating chamber cavity; Described interchanger is arranged at slightly near in the body of heater heating chamber cavity of windsheild, and the circular heat exchanger that described interchanger is multilayered structure, mainly by some copper pipes and gear piece, be welded, parallel with one anotherly between described copper pipe be connected with water tank with the inlet chest of peripheral hardware.
The invention has the advantages that: by interchanger, impeller and windsheild are arranged in body of heater, and by furnace wall surrounding, some airducts being set, and some nozzles over against workpiece are set on airduct bearing of trend, and increased air output, improved speed of cooling; In addition by being multi-layer annular interchanger by design of heat exchanger, and make copper pipe in circular heat exchanger assembly in parallel and be connected with water tank with external inlet chest, thereby improve heat transfer effect by changing the flow of the water by body, thus raising heat transfer effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of vacuum air-quenching furnace fast wind of the present invention cooling system.
Embodiment
A kind of vacuum air-quenching furnace fast wind cooling system shown in Fig. 1, is mainly comprised of ventilated machine 1, impeller 2, windsheild 3, airduct 4, nozzle 5, circular heat exchanger 6.Described ventilated machine 1 is the two-stage electric motor of turn/min of rotating speed 2800, 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 furnace wall bearing of trend, and end, airduct the same side and windsheild 3 welding, thereby airduct 4 forms air channel 9 with the small space of windsheild 3 and twere.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 is placed in enclosed cavity configuration 7, because the outlet of air quantity is uniform along body of heater surrounding, make air-out uniformity, thus 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 body of heater heating chamber cavity, mainly by some copper pipes and gear piece, be welded, and plumbers shed is parallel with one another and external inlet chest and water tank, the flow of the water passing through by change improves the heat transfer effect of interchanger.
