Abstract
The utility model relates to a tunnel furnace coil type cooling hearth; a plurality of rows of seamless copper tubes are fixed around the surface of a stainless steel hearth (3) to form a circulating cooling water pipe (1), tightly contact with the stainless steel hearth (3), and are respectively connected with a water inlet pipeline and a water outlet pipeline; heat conductive cement (6) is bonded and filled on the outer surface so as to form a heat conductive outer layer, so that the outer surface is firmly adhered on the surfaces of the stainless steel hearth (3) and the circulating cooling water pipe (1), and conducts the internal high-temperature heat to the circulating cooling water pipe (1); and the cooling water circulates, takes away the heat, and quickly cools the stainless steel hearth (3). Without contacting with the cooling water, the stainless steel hearth (3) is not eroded by impurities in the water; and the weld seams of the seamless copper tubes do not leak, thereby effectively avoiding equipment failure and work piece scrap caused by water leakage of the hearth, and effectively prolonging the service life of the stainless steel hearth (3) and a tunnel furnace.
Description
Technical field
The utility model relates to electronic product dedicated tunnel stove, relates in particular to the burner hearth device for cooling.
Background technology
At present, the domestic continuous tunnel furnace cooling burner hearth that is used for electronic device high temperature production operation, be to install metal-coating additional in metal burner hearth outside, with argon arc welding itself and metal burner hearth fixedly are welded as a whole, the interlayer inner space forms sealed whole body formula water jacket, in water jacket, feed the cold water circulation, be used for carrying out heat exchange and cool to burner hearth.Because the metal burner hearth is in the high-temperature work environment, cooling is with containing corrosive impurity in the recirculated water, long-term lasting the use can produce etch to the metal burner hearth, phenomenon such as occur leaking, infiltration and weld seam leak, the electronic device generation oxidation, the downright bad phenomenon that make metal burner hearth inside lower the temperature and cool off, finally cause metal burner hearth and whole continuous tunnel furnace to quicken to scrap, cause heavy economic losses.
Summary of the invention
The purpose of this utility model, just provide a kind of new construction burner hearth that cools, improve the type of cooling, avoid cooling water to the etch of metal burner hearth, prevent infiltration, drainage and consequent metal burner hearth oxidation damage, guarantee the crudy and the production safety of electronic devices and components, prolong the service life of continuous tunnel furnace and metal burner hearth.
Task of the present utility model is finished like this: design a kind of continuous tunnel furnace coiled burner hearth that cools, adopt the plurality of rows metal tube and ring on the stainless steel surface of burner hearth, to fix installing, constitute circulating cooling water pipe, outer surface bonding is filled heat-conducting daub and is constituted the heat conduction skin, circulating cooling water pipe and stainless steel burner hearth is solidified seal.Circulating cooling water pipe is made by seamless copper pipe, closely contact with the stainless steel burner hearth, the circulating cooling water pipe below stainless steel burner hearth arrival end is provided with water inlet, connects inlet pipeline, circulating cooling water pipe above stainless steel furnace outlet end sets out the mouth of a river, connects outlet pipeline.Make full use of absorption bonding, heat conduction that heat-conducting daub has and the natural characteristic that is subjected to heat cure, make it securely attached on stainless steel burner hearth and the recirculated cooling water tube-surface, in whole burner hearth and cooling device be locked in closely, when in continuous tunnel furnace, processing electronic devices and components, stainless steel burner hearth internal high temperature heat is fully conducted to circulating cooling water pipe, and cooling water charges into circulating cooling water pipe by water inlet, and trickling circulates, take away heat, realize stainless steel burner hearth fast cooling.Because the stainless steel burner hearth does not contact with cooling water, can not be subjected to impurity etch in the water, the used seamless copper pipe of circulating cooling water pipe does not have weld seam, there is not the welding seam leakage phenomenon, therefore stop stainless steel burner hearth infiltration drainage effectively, prevented the equipment fault and the product rejection that cause because of burner hearth percolating water.
Design and produce, test according to above-mentioned, proof the utility model is rational in infrastructure, good cooling results, stopped the etch of cooling water fully to the stainless steel burner hearth, fundamentally prevent infiltration, drainage and consequent burning corrosion and damage, ensured device security, guaranteed electronic devices and components hot-working quality, prolong the service life of stainless steel burner hearth and continuous tunnel furnace effectively, reached predetermined purpose preferably.
Description of drawings
Fig. 1 is circulating cooling water pipe of the present utility model (a 1) mounting structure schematic diagram;
Fig. 2 is that the A of Fig. 1 is to K-K section burner hearth cooling device structural representation.
Among the figure, 1-circulating cooling water pipe, 2-delivery port, 3-stainless steel burner hearth, 4-burner hearth fire door, 5-water inlet, 6-heat-conducting daub; A-line of vision symbol, K-section symbols, F-burner hearth arrival end, E-furnace outlet end, D-burner hearth cavity, M-heat-conducting daub outer layer surface.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Consult Fig. 1, the circulating cooling water pipe 1 that installing plurality of rows seamless copper pipe is made on the surface of stainless steel burner hearth 3, offering water inlet 5 on the circulating cooling water pipe 1 below the burner hearth arrival end F, be connected with inlet channel, setting out the mouth of a river 2 on the circulating cooling water pipe 1 above the furnace outlet end E, be connected with outlet conduit, recirculated cooling water enters circulating cooling water pipe 1 by water inlet 5, enter cooling bay by delivery port 2 by outlet conduit, in cyclic process, the heat of stainless steel burner hearth 3 is taken away, carried out the heat exchange cooling.On each surface around the stainless steel burner hearth 3, all gather and install circulating cooling water pipe 1, constituted coiled cooling system grid.
Consult Fig. 2, installed circulating cooling water pipe 1 around stainless steel burner hearth 3 whole surfaces, skin surrounds circulating cooling water pipe 1 sealing with heat-conducting daub 6 again, and boning as cement is fastened on the surperficial outer of stainless steel burner hearth 3, the outside troweling forms heat-conducting daub outer layer surface M.The burner hearth cavity D of sealing has formed the hot worked cooling of electronic devices and components tunnel.The high temperature of burner hearth cavity D conducts to cooling water by heat-conducting daub 6 and circulating cooling water pipe 1, by cooling water circulation trickling, makes stainless steel burner hearth 3 fast coolings, finishes the hot worked technical process that cools of electronic devices and components.
Circulating cooling water pipe 1 of the present utility model adopts φ 10～φ 15mm seamless copper pipe processing and fabricating, gather be looped around stainless steel burner hearth 1 around, closely contact with stainless steel burner hearth 1, heat-conducting daub 6 is smeared to be filled in and is smash densification on stainless steel burner hearth 1 surface in fact, constitute the confined bed thermosphere, as the floating surface of cement, form smooth smooth heat-conducting daub outer layer surface M.Electronic devices and components enter the cooling burner hearth by the heating furnace of continuous tunnel furnace, and workpiece temperature is cooled off by the long stainless steel burner hearth 3 of 200cm fast by 600 ℃ of high temperature, is cooled to about 100 ℃ and comes out of the stove.Compare with original whole water jacket recirculated water cooling mode, the utility model does not have the infiltration of leakage phenomenon, and good cooling results has guaranteed the electronic workpiece crudy, has prolonged service life of equipment.
