Abstract
The utility model relates to an industrial furnace, in particular to a circulating cooling device for an elevator furnace. The circulating cooling device comprises an elevator furnace body and a heat exchanger. The air outlet of the furnace body is connected with the air inlet of the heat exchanger with circulating cooling media arranged internally, the air outlet of the heat exchanger is connected with the air draft opening of an exhaust fan, and the air supply opening of the exhaust fan is communicated with the air inlet of the furnace body. According to the circulating cooling device, an air inlet condensation pipe, an air outlet condensation pipe, an upper gas cavity and a lower gas cavity form the heat exchanger so that gas can be cooled in sufficient time, and the cooling media can fully absorb heat. The circulating cooling device is small in size and good in heat exchange effect. In addition, the high-temperature protective gas is cooled through the circulating cooling device and conveyed to the furnace body to be recycled again, so that less protective gas is used and the cost is saved.
Description
Technical field
The utility model relates to industrial furnace, is specially bell-jar furnace circulating cooling device.
Background technology
For the electronic product of multiple-layer sheet ceramic capacitor and so on, generally adopt clock hood type furnace to carry out sintering.In laboratory, after electronic product adopts clock hood type furnace sintering, as nitrogen passes into body of heater, make the interior product of body of heater cooling protective gas, after cooling end, gas discharging is fallen.Yet, as suitability for industrialized production, just can not adopt the pattern in laboratory, the one, the cost increase that a large amount of protective gas brings is not suitable for the popularization of product, and the 2nd, the protective gas of a large amount of discharges is also subject to the restriction of environmental protection.Therefore, for the commercial Application of clock hood type furnace, have to consider recycling of protective gas.
Top-hat kiln circulating cooling system is in the past the cooling device of single tube passage.Because gas temperature in body of heater is higher, adopt the cooling device of single tube passage high-temperature gas will be down to normal temperature, make the size of cooling device larger, product volatile matter is easy to clean not, and long-time use can reduce heat transfer effect greatly.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of small volume, the good bell-jar furnace circulating cooling device of heat transfer effect.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of bell-jar furnace circulating cooling device, comprise clock hood type furnace body of heater and a heat exchanger, body of heater gas outlet with in be provided with circulating cooling medium described heat exchanger air inlet be connected, heat exchanger air outlet connects the suction opeing of an air exhauster, and the air outlet of this air exhauster is communicated with the air inlet of body of heater.
Further, described heat exchanger comprises the air intake condenser pipe that several air-out condenser pipes and several upper end are communicated with described air inlet respectively, described air intake condenser pipe lower end is communicated with air-out condenser pipe lower end by lower air chamber, air-out condenser pipe upper end is connected with upper gas chamber, and upper gas chamber is connected with described suction opeing.
As preferably, maintenance window has been opened in described heat exchanger bottom.
From above scheme, the utility model adopts outlet and inlet condenser pipe and upper and lower two air cavitys to form heat exchanger, can make gas have the sufficient time to carry out cooling, and cooling medium also can fully absorb heat, and not only equipment volume is less, and good effect of heat exchange.In addition, high temperature protection gas is cooling and again send body of heater back to and recycle by this cooling back installation, has reduced protective gas use amount and has saved cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional schematic of the utility model optimal way.
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2, introduce in detail a kind of bell-jar furnace circulating cooling device of the present utility model, it comprises clock hood type furnace body of heater 1 and a heat exchanger 2, body of heater gas outlet 11 with in be provided with circulating cooling medium described heat exchanger air inlet 21 be connected, heat exchanger air outlet 22 connects the suction opeing 31 of an air exhauster 3, and the air outlet 32 of this air exhauster is communicated with the air inlet 12 of body of heater.When heat exchanger is worked; air exhauster is delivered to heat exchanger by high-temperature gas by heat exchanger air inlet; cooling medium in heat exchanger is high temperature protection gas cooled, then via air exhauster, the gas after cooling sent in body of heater, thereby realizes recycling of protective gas.
In the utility model, described heat exchanger 2 comprises the air intake condenser pipe 24 that several air-out condenser pipes 23 and several upper end are communicated with described air inlet respectively, described air intake condenser pipe lower end is communicated with air-out condenser pipe lower end by lower air chamber 25, air-out condenser pipe upper end is connected with upper gas chamber 26, and upper gas chamber is connected with described suction opeing; Heat exchanger adopts outlet and inlet condenser pipe and upper and lower two air cavitys to form heat exchanger, can make gas have the sufficient time to carry out cooling, and cooling medium also can fully absorb heat, and not only equipment volume is less, and good effect of heat exchange.In implementation process, air intake condenser pipe and air-out condenser pipe can be arranged in parallel, and heat exchanger is double-layer cooling structure, and cooling medium utilization is abundant, can make gas fully cooling.
As preferably, maintenance window 4 has been opened in described heat exchanger bottom, can clean easily colloid and the foreign material that protective gas is taken out of in stove.
Above-mentioned embodiment is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that not departing from the utility model spirit and scope, can also make various variations and modification, therefore all technical schemes that are equal to belong to category of the present utility model.
