Description
Technical field
The utility model relates to a kind of drying unit, more particularly, relates to a kind of wiring board drying unit.
Background technology
At present, wiring board in order to carry out next step operation as early as possible, need be sent wiring board into drying unit and dry operation after washing.Existing drying unit, generally blower fan is installed on the sidewall of baking oven, by blower fan work the external heat source evolution of heat is poured in the casing, dry wiring board with this, the working method of this inside and outside cycle heat exchange heating has greatly been wasted the energy, and the efficient of oven dry is low, can't dry fully.
The content of utility model
The purpose of this utility model is to provide a kind of energy savings, wiring board drying unit that drying efficiency is high.
The technical scheme that the utility model adopts is: a kind of wiring board drying unit, comprise casing, be arranged on workpiece transport path, heater and blower fan in the casing, wherein, be provided with some exhaust outlets at wall box, exhaust outlet interlaces arranged distribution in the both sides up and down of transfer passage and communicates with the air outlet of blower fan by heater and forms the air-out passage, is provided with dividing plate between the inlet scoop of blower fan and transfer passage, equidistantly is laid with some air vents on the dividing plate.
Above-mentioned a kind of wiring board drying unit, described heater is some heating wires, heating wire is arranged side by side in the air-out passage.
A kind of wiring board drying unit of the above is provided with at least two split-flow baffles that are provided with setting side by side between the air outlet of blower fan and the heater, the head and the tail two ends of split-flow baffles at an angle.
The utility model is owing to adopted above-mentioned structure, in casing, form hot air circulating system by workpiece transport path, blower fan, heater and exhaust outlet, air circulation in the casing is added heat utilization, saved the energy greatly, be provided with dividing plate between the inlet scoop of blower fan and the transfer passage, be distributed with some air vents on the dividing plate, by some air vents, the more uniform inlet air of blower fan does not influence the conveying of workpiece; Be provided with at least two split-flow baffles that are provided with setting side by side between the air outlet of blower fan and the heater, the air-flow whirlpool is avoided forming at an angle in the head and the tail two ends of split-flow baffles, reaches the purpose that improves heat exchanger effectiveness; Be provided with some exhaust outlets side by side in the both sides up and down near passage, exhaust outlet can omnibearingly be dried workpiece, has improved drying efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is polycrystalline substance schematic diagram of the present utility model.
Among the figure: 1 is casing, and 2 is workpiece transport path, and 3 is heater, and 4 is blower fan, and 5 is exhaust outlet, and 6 are the air-out passage, and 7 is dividing plate, and 71 is air vent, and 8 is split-flow baffles.
The specific embodiment
Extremely shown in Figure 2 as Fig. 1, a kind of wiring board drying unit, comprise casing 1, be arranged on workpiece transport path 2, heater 3 and blower fan 4 in the casing 1, be provided with some exhaust outlets 5 at casing 1 sidewall, exhaust outlet 5 interlaces arranged distribution in the both sides up and down of transfer passage 2 and communicates with the air outlet of blower fan 4 by heater 3 and forms air-out passage 6, is provided with dividing plate 7 between the inlet scoop of blower fan 4 and transfer passage 2, equidistantly is laid with some air vents 71 on the dividing plate 7; Heater 3 is some heating wires, and heating wire is arranged side by side in air-out passage 6; Be provided with at least two split-flow baffles that are arranged side by side 8 between the air outlet of blower fan 4 and the heater 3, the head and the tail two ends of split-flow baffles 8 at an angle.
The utility model is when concrete the use, when workpiece enters casing 1, open blower fan 4, air in the casing 1 is sucked by the inlet scoop of blower fan 4 through dividing plate 7, and the air outlet of blower fan 4 is transported to air-out passage 6 then, through split-flow baffles 8 to heater 3,3 pairs of air of heater heat, from exhaust outlet 5 ejections the workpiece on the transfer passage 2 is carried out omnibearing oven dry operation then, the hot gas that uses continues to be sucked by the inlet scoop of blower fan 3, circulates with this.
