Description
Technical field
The utility model relates to a kind of pcb board baking box energy saver.
Background technology
At present in the process of printed circuit board (PCB), need after character printing to carry out baking box stoving process, print principle transfers on pcb board by character graphics by half tone, and the legend ink of hygrometric state is mainly dried by hot air circulation mode by baking box, and the air of baking box inside needs constantly circulation.The temperature taking waste gas in baking box away is 150 DEG C, and this portion is directly drained by workshop exhaust duct, and cold air supplements and reheats into baking box, and the heat in this way waste gas is bending to be slatterned, the energy that loss is more.Along with the market competition of PCB industry is day by day strong, raw material unit price rises steadily, improving constantly of staff salary, adds country and carries out connecing energy-conserving and environment-protective policy, need to develop a kind of energy saver, reduce baking box power consumption.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of pcb board baking box energy saver, uses waste gas residual heat heating to enter the cold air of baking box, reduces baking box power consumption, energy-conserving and environment-protective.
The utility model solves the technical scheme that its technical problem adopts:
A kind of pcb board baking box energy saver, include heat exchanger, described heat exchanger is provided with cold wind import, cold wind exports, hot wind inlet and hot-blast outlet, described hot wind inlet and hot-blast outlet are oppositely arranged, described cold wind outlet connects baking box air inlet by the first airduct, described hot wind inlet connects baking box exhaust outlet by the second airduct, described hot-blast outlet connects workshop exhaust duct by the 3rd airduct, described heat exchanger inside arranges some heat exchanger tubes, described heat exchanger tube two ends respectively with hot wind inlet, hot-blast outlet is communicated with, filter screen is provided with in described cold wind import.
As the improvement of technique scheme, described heat exchanger tube adopts stainless steel manufacture.
As the further improvement of technique scheme, the distance between described heat exchanger tube and heat exchanger inwall is greater than the external diameter of heat exchanger tube.
Further, described heat exchanger tube is provided with six row, and two row heat exchanger tubes of arbitrary neighborhood shift to install.
Further, described filter screen is made up of the filter pulp that two-layer density is different, and the filter pulp that its Midst density is larger is arranged on outside.
Further, described heat exchanger outer wall is provided with plastic insulating cover.
The beneficial effects of the utility model are: the waste gas that baking box is discharged enters heat exchanger from hot wind inlet, heat exchanger tube through heat exchanger inside is drained from hot-blast outlet, the cold air supplemented into baking box enters heat exchanger from the cold wind import of heat exchanger, heated at heat exchanger inner cold air contact heat-exchanging pipe, then entered baking box through cold wind outlet, the first airduct; Heat heat exchanger tube by waste gas, then heated the cold air entering baking box by heat exchanger tube, reduce the heating power consumption of baking box, economize energy, reduces costs.The utility model practicality rational in infrastructure, transformation is simple, and cost is low, is suitable for promoting on a large scale.
