Description
Technical field
The utility model relates to a kind of vacuum heat treatment device, the low pressure air cooling vacuum annealing oven that particularly a kind of speed of cooling is controlled.
Background technology
Air cooled vacuum heat treatment furnace is a kind of known equipment for Heating Processing, is mainly used in various cold-work die steel, hot-work die steel, rapid steel and stainless thermal treatment, also for tool steel annealing, has non-oxidation, without decarburization, degreasing, degassed advantage.But existing general air cooled vacuum heat treatment furnace has the following disadvantages when being used for vacuum annealing: because the heat insulation effect of this stove is better, when needs perform furnace cooling technique, need to cool for a long time, cause heat treatment cycle long, plant factor is low, consumes energy high; Equipments Setting is too high, as being configured with high-power ventilated machine, body of heater etc. that compressive strength is high, thus adds the manufacturing cost of equipment.
Summary of the invention
The purpose of this utility model is to provide that a kind of equipment manufacturing cost is low, energy consumption is low, quick cooling time good cooling results, furnace cooling time speed of cooling controlled low pressure air cooling vacuum annealing oven.
Technical solution of the present utility model is: the low pressure air cooling vacuum annealing oven that a kind of speed of cooling is controlled, comprise body of heater, heating chamber, heat exchanger, axial fan, cold wind motor and agitation fan, stir blower fan, it is characterized in that being provided with air flow duct between body of heater and heating chamber, heating chamber two relatively holding furnace wall are respectively equipped with entering of being connected with air flow duct, air outlet, the inlet and outlet place of heating chamber outside is respectively equipped with heating chamber air port to be opened/closed plugging device, heat exchanger and axial fan is provided with successively between the heating chamber and body of heater of air outlet side, axial fan is connected with the cold wind motor be arranged on outside body of heater, agitation fan is provided with in the heating chamber of blast inlet side, agitation fan is connected with the stirring fan shaft be located at outside body of heater.
There is windsheild in the outer setting of heat exchanger, form heat transfer space.
Heating chamber air port plugging device moves by sealing plate and drive sealing plate the cylinder opened or closed into and out of air port to form, and sealing plate connects with cylinder piston, and cylinder is arranged on outside body of heater.
Feature of the present utility model is: can control the inlet and outlet opened and closed heating chamber being provided with, and when heating and be incubated, ventilation opening is closed, and heat radiation is few; When furnace cooling, can according to process for cooling requirement, controlled cooling model speed, thermal effectiveness is good, and circulating cooling heat exchange efficiency is high, and save the energy, running cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Be described in further detail below in conjunction with accompanying drawing:
As shown in the figure, the utility model is mainly made up of body of heater 3, heating chamber 1, heat exchanger 11, axial fan 9, cold wind motor 8, agitation fan 12, stirring blower fan 4.Body of heater adopts Plate Welding to form, the heating chamber arranged in it adopts heat preserving and insulating material to make, air flow duct 13 is had between body of heater and heating chamber, the front and back of heating chamber are relatively incubated on furnace wall and are provided with blast inlet 7 and air outlet 14, the present embodiment establishes 2 blast inlets and 2 air outlets, is connected into and out of air port with air flow duct.On air port, be provided with heating chamber air port plugging device, be made up of sealing plate 6 and cylinder 5, sealing plate connects with the piston being fixedly mounted on the cylinder 5 outside body of heater, drives sealing plate to move, open or close air port by cylinder.Heat exchanger 11 and axial fan 9 is provided with successively between the heating chamber and body of heater of air outlet side, the outer setting windsheild 10 of heat exchanger, form heat transfer space, ensure that the air-flow flowed out from heating chamber enters the air flow duct between heating chamber and body of heater after heat exchanger.Axial fan is connected with cold wind motor shaft, and cold wind motor is arranged on outside body of heater.The agitation fan arranged in the heating chamber of blast inlet side is connected with stirring fan shaft, stirs blower fan and is located at outside body of heater.
During operation, open fire door and load workpiece 2, start cylinder and drive sealing plate to make its shutoff inlet and outlet, then start heating, start the stirring blower fan of hot air circulation during heating, make in-furnace temperature even, because heating chamber insulation furnace wall is completely closed, heat radiation is little, good energy-conserving effect.During workpiece annealing cooling, according to the rate request of cooling, following 4 kinds of cooling rate control modes can being performed: one is temperature control cooling, when namely cooling rate is too fast, reducing cooling rate by being interrupted heating; Two is drive sealing plate to move by cylinder, opens inlet and outlet, accelerates cooling; Three is in heating chamber, inject a certain amount of high pure nitrogen by blast inlet, accelerates cooling; Four is open ventilated machine again injecting high pure nitrogen while, axial fan rotates under it drives, furnace gas is made to flow out from air outlet fast, and heat exchanger is passed through under the restriction of windsheild, gas is lowered the temperature, then along arrow direction flowing in air flow duct and figure, then heating chamber formation circulating cooling workpiece is entered from blast inlet.
