One, technical field
The utility model relates to a kind of cooling device, particularly a kind of vacuum electric furnace heat exchange type high pressure positive blower gas circulation cooling device.
Two, background technology
Nitriding electric furnace is the agglomerating plant of using always, and the nitriding electric furnace energy consumption of using at present is all very high, for energy savings, generally all be provided with reasonable insulation construction to save electric power, yet insulation construction causes the nitriding furnace heat radiation just few, temperature descends slow, and particularly temperature decline is slower in the time of 1000 ℃, owing to be to feed nitrogen (N in the stove
2), at high temperature be unfavorable for producing, prolong life cycle of the product and production efficiency, therefore how solving in the stove under blanket of nitrogen fast, cooling is the problem of very being concerned about in producing.
Three, utility model content
At above-mentioned situation, the purpose of the utility model just provides a kind of vacuum electric furnace heat exchange type high pressure positive blower gas circulation cooling device, can effectively solve the quick cooling problem of vacuum electric furnace under blanket of nitrogen.The technical scheme of its solution is, include heat exchanger and high pressure positive blower, heat exchanger links to each other with the high pressure positive blower air inlet, high pressure positive blower is contained on the vacuum seal motor, drive the blower fan high speed rotating, on the high pressure positive blower exhaust outlet gas distributor is housed, escape pipe is arranged on the gas distributor, said heat exchanger is that the air inlet mouth of pipe and the mouth of pipe of giving vent to anger are equipped with in the housing top and the bottom, the mouth of pipe of giving vent to anger is connected with the high pressure positive blower air inlet, and housing has every putting plate at two ends up and down, and the logical heat-exchange tube of current is housed between two plates, there is seal cover at the heat exchanger shell two ends, and water inlet and delivery port are arranged on the end cap.The utility model is simple in structure, and novel unique, easy for installation, result of use is good, is N in guaranteeing stove always
2Under the atmosphere, quicken cooling, enhance productivity, can guarantee to prevent simultaneously the not oxidation of resistance to oxidation material again, improve stove service life, this is N
2On vacuum electric furnace is produced under the atmosphere one created greatly, and it promotes the use of huge economic benefit.
Four, description of drawings
Fig. 1 is a structural profile front view of the present utility model.
Fig. 2 be among Fig. 1 of the present utility model A-A to cross section view.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
By shown in Figure 1, the utility model includes heat exchanger and high pressure positive blower, the mouth of pipe 15 of giving vent to anger of heat exchanger 1 links to each other with high pressure positive blower 2 air inlets, high pressure positive blower 2 is contained on the vacuum seal motor 3, drive the blower fan high speed rotating, on high pressure positive blower 2 exhaust outlets gas distributor 4 is housed, escape pipe 6 is arranged on the gas distributor, said heat exchanger 1 is that the air inlet mouth of pipe 8 and the mouth of pipe 15 of giving vent to anger are arranged on the side, housing top and the bottom, the mouth of pipe 15 of giving vent to anger is connected with high pressure positive blower 2 air inlets through flange and tracheae 5, housing has every putting plate 16 at two ends up and down, the logical heat-exchange tube 14 of current is arranged between two plates, the heat exchanger shell two ends have on seal cover 7, one end caps water inlet 9 are arranged, and the other end has covered delivery port 10.
In order to guarantee the result of use of heat exchanger 1, the housing inner face of heat exchanger has water leg 13, hull outside has water inlet 17 and the delivery port 12 that is communicated with water leg 13, and 14 of heat-exchange tubes are equipped with the spoiler 11 of transversion malposition (promptly perpendicular to tube wall) in the housing, to strengthen the heat exchange effect.
The utility model in use, the escape pipe 6 of gas distributor 4 inserts in the nitriding electric furnace, the denitrogen gas port of nitriding electric furnace and the nitrogen inlet of heat exchanger be connected (being the air inlet mouth of pipe 8), connect the cold water source capsule on the water inlet pipe mouth, when high pressure positive blower is worked, the high temperature nitrogen of coming from nitriding furnace is drawn in the heat exchanger, because what flow in water leg and the heat-exchange tube is cold water, through heat exchange, the nitrogen temperature is lowered, nitrogen after the cooling is pumped into gas distributor by high pressure positive blower, send in the stove through the distributor escape pipe, make fast cooling in the stove, in stove, be heated, nitrogen enters heat exchanger once more, circulates benignly according to this.
This shows, the heat exchanger of water nitrogen is extracted the high temperature in the electric furnace (nitrogen) gas and pressurization out through the over-heat-exchanger cooling with high pressure positive blower, again send into stove in by gas distributing opening cooled nitrogen, circulation cooling like this, both can guarantee in the stove it is N2 atmosphere always, can quicken cooling again, after tested, cooling velocity can improve 6 times under 1000 ℃, and cooling velocity is than cooling is faster naturally during low temperature, shorten cool time, production cycle shortens 25%, shortens 1.5 times than cooling production cycle naturally, and since the cooling cooling soon, the furnace lining of vacuum drying oven when be not anti-nitride material, as graphite, carbon class etc., can guarantee to protect lining can be not oxidized or slow down nitriding velocity, increases the service life, save production cost, enhance productivity.Therefore, the production of succeeding in developing to nitriding electric furnace of the present utility model provides good condition, and it is applied and must produce huge economic benefit, and is the new bright prospect of production developing of nitriding electric furnace.
