Detailed Description

The details of the present invention are described below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, an interior decoration baking finish drying device is characterized in that: comprises a box body 1, an electric control cabinet 4, a fresh air inlet 5, a fin heater 7 and a feed inlet 3.

As shown in fig. 4 and 5, a back plate 10 is arranged on the back surface of the box body 1, a fresh air inlet 5 is arranged on the left side surface of the box body, and a filtering device is arranged at the position of the fresh air inlet 5. The heating device is characterized in that a plurality of heating pipes and fin heaters 7 which are uniformly distributed are arranged in the box body 1, and the fin heaters 7 are connected with an external heat source. An inclined plane is arranged on one side of the upper portion of the box body 1, and an observation window 2 is arranged on the inclined plane.

As shown in fig. 3, an electric control cabinet 4 is installed on the right side of the box body 1, and the electric control cabinet 4 controls the temperature of the heating pipe and the rotating speed of the fan 9. The right side of the box body 1 is also provided with a feed inlet 3, the feed inlet 3 can be closed and opened, and the bottom of the feed inlet 3 is flush with a commodity shelf 8 in the box body 1. The bottom of the box body 1 is provided with a fan 9, the bottom of the back plate 10 is communicated with an exhaust pipe 6, the exhaust pipe 6 is connected with a waste gas treatment mechanism, and a fresh air inlet 5 is connected after treatment.

In one example, the external heat source to which the fin heater 7 is connected is hot water or hot air.

In one example, the tank 1 is provided with a double structure therein, and is separated from a stainless steel plate on which the fin heater 7 is mounted by a bracket.

In one example, the fans 9 are provided in plurality and are uniformly arranged at the bottom of the box body 1.

In one example, the observation windows 2 are two, and heat-resistant glass is mounted.

In one example, the rack 8 is provided with a slide rail, and the automotive interior parts are sent in and taken out through the slide rail.

In one example, the shelf 8 is multi-layered and coated with heat-resistant asbestos.

The working process of the invention is as follows:

according to the invention, the air door is adjusted to the paint baking position, hot air is circulated, and the temperature in the box body 1 is rapidly raised to the preset drying temperature of 55-60 ℃. After the fan 9 carries out the prefiltering with outside fresh air, send to the air chamber at box 1 top after taking place heat exchange with the heat energy converter, through the second filtration purification again, hot-blast internal circulation effect through the air door, except that the small amount of fresh air of inspiration, the vast majority hot-air is continued the heating again and is utilized for temperature progressively rises in the box 1. When the temperature reaches the set temperature, the fin heater 7 is automatically stopped. When the temperature drops to the set temperature, the fan 9 and the fin heater 7 are automatically started again, so that the temperature in the box body 1 is kept relatively constant. And finally, when the paint baking time reaches the set time, the box body 1 is automatically shut down, and the paint baking is finished. The baking finish comprises pretreatment, painting and drying at about 180 ℃.

The working principle of the invention is as follows:

the hot air flow moves forward from the tail part and is fully contacted with the automotive upholstery, and the heat transfer quantity is fully utilized through heat conduction, convection and radiation. The heat energy is directly transferred to the material, so that the moisture of the automotive interior part is continuously evaporated in the box body 1, and the air inducing device at the feeding port draws out a large amount of moisture and wet air flow, thereby preventing the secondary pollution caused by the discharge of dust. The automotive interior part enters through the feeding hole 3, and the automotive interior part is automatically pushed to enter, so that the whole drying process is completed. And the countercurrent conduction dehumidification is adopted, so that repeated drying procedures are avoided. Meanwhile, after the exhaust pipe 6 treats the waste gas, the air with the waste heat is mixed into the box body 1 through the fresh air inlet, so that the loss of heat is avoided.

In conclusion, the waste heat treatment device makes full use of heat through heat conduction, convection and radiation, and meanwhile, the waste heat of waste gas is greatly reduced due to the arrangement of the waste gas treatment mechanism.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the technical spirit and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art.
