The vacuum furnace cooling system comprises a vacuum furnace body (1), a first high-vacuum baffle valve (2), a heat exchanger (3), an induced draft fan (4), a refrigerated air dryer (5), an electromagnetic valve (6) and a second high-vacuum baffle valve (7) which are connected according to the sequence of the vacuum furnace body (1), the heat exchanger (3), the first high-vacuum baffle valve (2), the electromagnetic valve (6), the induced draft fan (4), the refrigerated air dryer (5) and the second high-vacuum baffle valve (7) by using a pipeline. A cooler medium gas exchanges heat with a cooled material, and thus the cooling time of the material is greatly shortened, and the working efficiency of the furnace body is increased.
Description
Technical field
The utility model relates to a kind of body of heater cooling system, particularly a kind of stove external circulation cooling system that is applicable to vacuum drying oven.
Background technology
In the past, mainly contained following several to the type of cooling of vacuum drying oven: circulating cooling in the first, stove, utilize exactly the air blast of body of heater inside to drive furnace gas and flow, by the built-in heat exchanger heat exchange, reach the purpose of cooling material; The second, the stove outer circulation is cooling, utilizes exactly air-introduced machine that gas is drawn, and through the outer water cooling heat exchanger of stove, returns in stove, realizes the purpose of cooling material; The third utilizes the combination of the interior circulation of stove and stove outer circulation cooling exactly.The above type of cooling is all to adopt the cooling mode of water cooling heat exchanger, due to the restriction of heat transferring medium water self temperature, makes the time of cooling consumption longer, affects production efficiency.
The utility model content
The purpose of this utility model is to provide the higher vacuum drying oven of a kind of cooling effectiveness cooling system, shortens the time of cooling consumption, enhances productivity.
To achieve these goals, the utility model provides a kind of vacuum drying oven cooling system, comprising: use pipeline according to the vacuum furnace body that is linked in sequence (1), the first cap of high-vacuum baffle valve (2), heat exchanger (3), air-introduced machine (4), cooling driers (5), magnetic valve (6) and second cap of high-vacuum baffle valve (7) of vacuum furnace body (1)-heat exchanger (3)-first cap of high-vacuum baffle valve (2)-magnetic valve (6)-air-introduced machine (4)-cooling driers (5)-second cap of high-vacuum baffle valve (7)-vacuum furnace body (1).
The cooling system of vacuum drying oven described in the utility model uses flange or thread connecting mode with pipeline series connection described vacuum furnace body (1), the first cap of high-vacuum baffle valve (2), heat exchanger (3), air-introduced machine (4), cooling driers (5), magnetic valve (6) and the second cap of high-vacuum baffle valve (7).
The cooling system of vacuum drying oven described in the utility model, described magnetic valve (6) is also connected to extraneous gas, when the beginning outer loop is cooling, described magnetic valve (6) is opened, to introduce extraneous gas between the first cap of high-vacuum baffle valve (2) and the second cap of high-vacuum baffle valve (7), make the air pressure between the first cap of high-vacuum baffle valve (2) and the second cap of high-vacuum baffle valve (7) equate with air pressure in described vacuum furnace body (1).
System cooling according to vacuum drying oven of the present utility model, because by the chilling temperature of cooling driers fast reducing refrigerating gas, make the temperature difference that is cooled between material and refrigerating gas larger, so cooling effectiveness is higher outside body of heater, shorten the time of cooling consumption, improved production efficiency.
Description of drawings
Fig. 1 is the agent structure schematic diagram according to the vacuum drying oven cooling system of the utility model one embodiment.
The specific embodiment
Describe the utility model in detail referring to accompanying drawing.
As shown in Figure 1, the vacuum drying oven cooling system according to the utility model one embodiment mainly comprises: vacuum furnace body 1, cap of high-vacuum baffle valve 2, heat exchanger 3, air-introduced machine 4, cooling driers 5, magnetic valve 6, cap of high-vacuum baffle valve 7.
Above-mentioned each parts all fixedly mount, and are together in series with pipeline by for example flange or thread connecting mode, form closed external circuit.Concrete order is, the front outlet of vacuum furnace body 1 connects the air inlet of heat exchanger 3, the gas outlet of heat exchanger 3 connects the air inlet of cap of high-vacuum baffle valve 2, the gas outlet of cap of high-vacuum baffle valve 2 connects the air inlet of air-introduced machine 4, the gas outlet of air-introduced machine 4 connects the air inlet of cooling driers 5, the gas outlet of cooling driers 5 connects the air inlet of cap of high-vacuum baffle valve 7, and the gas outlet of cap of high-vacuum baffle valve 7 connects the air inlet of vacuum furnace body 1.
Operation principle and the operating procedure of above-mentioned cooling system below are described.
1, the gas quenching but before
Vacuum furnace body 1 has the vacuum system of oneself.When beginning to vacuumize, open cap of high-vacuum baffle valve 2 and cap of high-vacuum baffle valve 7, outer loop is vacuumized together with vacuum furnace body 1.At this moment, air-introduced machine 4 and cooling driers 5 are not all opened.When reaching the vacuum requirement, close cap of high-vacuum baffle valve 2 and cap of high-vacuum baffle valve 7, then be filled with argon gas in the pipeline of opens solenoid valve 6 between two cap of high-vacuum baffle valves, until reach a standard atmospheric pressure.At this moment, vacuum furnace body 1 continues to complete the subsequent operation of himself, for example, heats, continues to vacuumize, complete dehydrogenated operation.
2, the gas quenching but after
When applying argon gas gas was quenched, the blower fan of opening vacuum furnace body 1 inside was cooling.When the temperature in vacuum body of heater 1 drops to about 70 degrees centigrade by about 500 degrees centigrade, stop blower fan.Then, open simultaneously cap of high-vacuum baffle valve 2 and cap of high-vacuum baffle valve 7, and open air-introduced machine 4 and cooling driers 5.Like this, under the effect of air-introduced machine 4, the gas in vacuum furnace body 1 begins the stove outer circulation, and gas is dropped in 45 degrees centigrade by 70 degrees centigrade of left and right through heat exchanger 3 temperature; Gas is through after cooling driers 5, and because cooling driers 5 can be cooled to 45 degrees centigrade of gases with interior large flow rapidly in 10 degrees centigrade, thereby temperature drops to 5～10 degrees centigrade of left and right, and then gets back in vacuum furnace body 1.Cooled gas because himself temperature is lower, can be realized heat exchange with the material that be cooled rapidly, reaches the purpose of quick cooling material.
What need statement is that above-mentioned utility model content and the specific embodiment are intended to illustrate the practical application of technical scheme provided by the utility model, should not be construed as the restriction to the utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, being equal to and replacing or improve.Protection domain of the present utility model is as the criterion with claims.
