Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Specific embodiment:
With reference to Fig. 1 composition graphs 2, the utility model discloses a kind of waste gas recovering device of reflow machine, comprise collection box 1, air inlet 2, recovery port 3, exhaust outlet 4 and cooling device 5; Described air inlet 2 is arranged on the left end of collection box 1; Described recovery port 3 is arranged on the lower end of collection box 1; Described exhaust outlet 4 is arranged on the right-hand member of collection box 1; The inner side of described exhaust outlet 4 is provided with spoiler 41.Described cooling device 5 comprises water pipe 51 and several heat sink assemblies 52; Described water pipe 51 is arranged on the inside of collection box 1; Described water pipe 51 is U-shaped water pipe; The inner side of U-shaped water pipe is provided with two rows heat sink assembly 52; Two rows heat sink assembly 52 is symmetrical mutually; The top of two rows heat sink assembly 52 contacts with each other, and forms the netted combining structure of heat sink assembly 52, is more conducive to the fast cooling to hot blast.The top of described collection box 1 sidewall is provided with first interface 11; The bottom of described collection box 1 sidewall is provided with the second interface 12; Described first interface 11 is connected with the delivery port of water pipe 51; Described second interface 12 is connected with the water inlet of water pipe 51; Several heat sink assemblies 52 described are set up in parallel along the outer wall of water pipe 51; The base of several heat sink assemblies 52 described is fitted on the outer wall of water pipe 51; Each heat sink assembly 52 described includes L shape fin 521 and a 2nd L shape fin 522; A described L shape fin 521 and the 2nd L shape fin 522 specular each other; The side of a described L shape fin 521 and the side of the 2nd L shape fin 522 fit.A described L shape fin 521 is aluminum the one L shape fin; Described 2nd L shape fin 522 is aluminum the 2nd L shape fin.
During use, the hot blast of reflow machine is passed into collection box 1 from air inlet 2, through the plane residing for heat sink assembly 52, directly contact with cooling device 5, improve filter efficiency.Simultaneously, being passed into by the water of 10 ~ 20 DEG C enters water pipe 51 from the second interface 12, because the L shape fin 521 in heat sink assembly 52 and the 2nd L shape fin 522 increase the contact area of cooling device 5 and hot blast, the temperature of hot blast can be made rapidly to be reduced to 20 ~ 30 DEG C from 100 ~ 120 DEG C by heat trnasfer, solder(ing) paste post liquefaction in hot blast is gathered in the bottom surface of collection box 1, flows out to be collected reuse by recovery port 3.Gas through filtering is discharged from exhaust outlet 4.Water in water pipe 51 is discharged from first interface 11.Passed into from below by water, the mode of discharging from top, be conducive to the discharge of incoagulable gas, heat transfer effect is better.Use the utility model can reach 70% ~ 85% to the rate of recovery of solder(ing) paste.
