Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

See accompanying drawing 1,2, the utility model comprises blowing dryer 10, baker 20, the going into of baker 20, exit end are provided with guide wheel group 30, and baker 20 is positioned at the side of blowing dryer 10, and the blast inlet 12 of blowing dryer 10 is connected to the heat exchanging pipe (not shown) of baker waste pipe.

Described blowing dryer 10 is made of square steel bar, square steel bar offers cross through hole, the cross through hole two ends are equipped with inlet tuyere 14 and outlet tuyere 16, and the bottom of blowing dryer 10 offers blast inlet 12, and blast inlet 12 1 ends are communicated with cross through hole, the other end is connected wind inlet channel 60.

The inlet end of described baker 20 is provided with baffle plate 50, and baffle plate 50 is positioned at guide wheel group 30 tops and towards blowing dryer 10 lopsidedness, baffle plate 50 can be introduced the hot blast of being discharged by the outlet tuyere 16 of blowing dryer 10 in the baker 20.

Dry up and drying effect for reaching to strengthen, this dehumidification system adopts following scheme:

The cabling precision of copper cash when (1) improvement dries up.Blowing dryer 10 is installed between outlet of annealing boiler tube and the accurate location of the row guide wheel group 30.The annealing boiler tube is when passing the flume wall of upper tank 70, and the precision of perforate has determined the positional precision and the parallelism of annealing boiler tube on flume wall.Water nozzle 72 is installed in the outlet of annealing boiler tube, and smooth surface and the attrition resistant porcelain bead of diameter a 3～4mm is installed in the water nozzle 72, limits copper cash 40 and can only move about in this diameter range when going out to anneal boiler tube.Guide wheel group 30 is installed on the centering mounting groove, all has axle bed to support thinner guide wheel shaft between per two guide wheels, thus walk on guide wheel copper cash 40 all in one plane.The thickness deviation that axle bed supports is less than 0.1mm, thus between the guide wheel apart from tolerance less than 0.1mm.Blowing dryer 10 is installed in near, the dried up mouth of guide wheel group 30 72 position far away, copper cash 40 in the cabling deviation at water nozzle 72 places in 3～4mm scope, in the cabling deviation at guide wheel place about 0.1mm, so in the cabling deviation at blowing dryer 10 places about 1～1.5mm.

(2) improve blowing dryer 10 tuyere setting accuracies.Drill through the hole with a solid steel bar tuyere is installed, and in steel pipe vertical axis direction boring tuyere is installed and is compared, the concentricity of inlet wire and outlet tuyere the and laterally parallelism of each tuyere axis is all more guaranteed can improve the setting accuracy of tuyere greatly.In addition, after high-pressure blast enters through hole from the through hole middle part, the flow direction at through hole inner high voltage wind is clearly separated, discharge by inlet tuyere 14 and outlet tuyere 16 respectively, copper cash 40 moves to the long distance effect that the through hole middle part time is subjected to the reversed flow high-pressure blast from inlet tuyere 14, has strengthened the effect that surface-moisture is blown out, and copper cash 40 moves to blowing dryer 10 when outer by the through hole middle part, be subjected to the wind action of forward high pressure, copper line surface moisture can be blown out.

(3) hot blast of high pressure positive blower extraction and the heat exchange of waste discharge hot gas.The temperature of enameling machine oven waste discharge hot gas is usually more than 300 degree, outside the waste discharge chimney, do an interlayer and constitute heat exchanging pipe, high pressure positive blower extracts the air through the interlayer heat exchange, send into blowing dryer 10 through wind inlet channel 60, so the high-pressure blast temperature that high pressure positive blower blows out can remain between 50～80 degree, makes it more to help drying up and drying.

(4) reduce tuyere diameter lengthening tuyere length.Because copper cash cabling precision and tuyere setting accuracy are all higher, after reducing, can not cause the tuyere diameter of bore friction of copper cash and tuyere inner hole wall yet, still can walk in the tuyere center, so the tuyere diameter can be reduced to 3mm, length is increased to 32mm.In so elongated passage, the moisture on copper cash 40 surfaces is difficult under the high back voltage wind action and passes through, and well dries up effect so can reach.Because the tuyere diameter is little, high-pressure blast is few from the effusive air quantity of tuyere, and the optional usefulness of high pressure positive blower is lower-powered can to meet the demands as 1.5KW.Since copper cash 40 with tuyere friction, tuyere does not have wear problems, so tuyere can be with material manufacturings such as common nylon.

(5) above guide wheel group 30, tilt to install a glass baffle plate 50, will blow to from the high-pressure hot wind that the outlet tuyere blows out in the oven dry air channel 20.This moment, the blast of high-pressure hot wind reduced, but its heat and flow velocity is bigger to the moisture evaporation effects of copper cash 40 surface remnants faster.

In sum, the beneficial effects of the utility model have: guaranteed the cabling when copper cash dries up The phenomenon of doing can not appear blowing because of certain root copper cash Disalignment not in precision, integral body dry up and Good drying effect and stable; After having utilized the baker waste gas residual heat, power consumption only has 1.5KW, Greatly saved the energy.
