Abstract
The utility model relates to an external heating system for a coating line oven and belongs to the technical field of coating line oven heating. The external heating system for the coating line oven comprises a product oven body and a heating device. A hot air inlet is formed in the top of the product oven body, a cold air outlet is formed in the lower portion of the product oven body, the hot air inlet is communicated with a hot air outlet of the heating device through a hot air pipeline, the cold air outlet is communicated with a cold air inlet of the heating device through a pipeline, and a circulating fan is arranged on a pipeline between the cold air outlet and the cold air inlet. According to the external heating system for the coating line oven, an external closed heating system relative to the product oven body is formed, so that resources are reused, the production cost is reduced, products are prevented from being directly heated by a heating element, even heating is guaranteed, and the phenomenon of product deformation due to uneven heating of the products is avoided.
Description
Technical field
The utility model relates to a kind of external heat system for the spraying coating line baking oven, belongs to the technical field of heating of spraying coating line baking oven.
Background technology
At present, the spraying sector application is more and more extensive, the spraying oven device is also a step very crucial in spraying process, and what usually adopt is the inner heating of baking oven, and main mode of heating is divided into: product top heating, product bottom heating and carry out simultaneously product upper and lower heating.This method in use, owing to being the heating of direct heating source, heating-up temperature is not easy to control, and the heat skewness, each heating is all fast near the product heating at heating source place, so the phenomenon such as deformation of products often occurs.Also attempted in the past with several equally distributed heating sources, product being heated, but effect is still less obvious, product also can occurs because heating the inhomogeneous deformation of products that causes.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of external heat system for the spraying coating line baking oven is provided, has avoided product because heating the inhomogeneous phenomenon that causes deformation of products.
External heat system for the spraying coating line baking oven described in the utility model, comprise product oven and heater, it is characterized in that: offer the hot blast import at product oven top, product oven bottom offers the cold wind outlet, the hot blast import is communicated with the hot-blast outlet of heater by advancing hot air duct, the cold wind outlet is communicated with the cold air inlet of heater by pipeline, on the pipeline between cold wind outlet and cold air inlet, circulating fan is installed.
In order further to guarantee the cleanliness factor of circulated air used, be provided with filter mechanism on the outlet of described circulating fan and the pipeline between cold air inlet.
Wherein, preferred described filter mechanism comprises prefiltration net and smart screen pack, and smart screen pack is positioned at prefiltration net right side, and the filtering accuracy of smart screen pack is greater than the prefiltration net.Adopt the mode of screen pack to filter, also controlled cost when reaching circulated air filtration purpose.
In order further to make circulated air to the product homogeneous heating, the corresponding hot blast import of described product oven inner top is provided with air dispersion plate.
The heating element heater of the preferred described heater of the utility model is heat-generating pipe, and firing rate is fast, successful.
Compared with prior art, the utlity model has following beneficial effect:
Consist of the external closing type heating system of a relative product oven by the utility model, realized that resource utilizes once again, reduced production cost.Avoided heating element heater directly product to be heated during use, but by heater, wind has been heated, then under the effect of circulating fan, the circulating hot water after heating has been drawn in the product oven.Be circulated air due to what product was heated, circulated air will all heat the every place of product after carrying out in the product oven, has guaranteed homogeneous heating, has prevented that product is because heating the inhomogeneous phenomenon that causes deformation of products.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, advance hot air duct 2, air dispersion plate 3, product oven 4, circulating fan 5, prefiltration net 6, smart screen pack 7, heater 8, heat-generating pipe.
The specific embodiment
Below the utility model is described in further detail by specific embodiment; but not in order to limit the utility model; all within the present invention spirit and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
As shown in Figure 1, the external heat system that is used for the spraying coating line baking oven, comprise product oven 3 and heater 7, offer the hot blast import at product oven 3 tops, product oven 3 bottoms offer the cold wind outlet, the hot blast import is communicated with the hot-blast outlet of heater 7 by advancing hot air duct 1, the cold wind outlet is communicated with by the cold air inlet of pipeline with heater 7, on the pipeline between cold wind outlet and cold air inlet, circulating fan 4 is installed, is provided with filter mechanism on the outlet of described circulating fan 4 and the pipeline between cold air inlet.
In the present embodiment, described filter mechanism comprises prefiltration net 5 and smart screen pack 6, and smart screen pack 6 is positioned at prefiltration net 5 right sides, and the filtering accuracy of smart screen pack 6 is greater than prefiltration net 5; The corresponding hot blast import of described product oven 3 inner tops is provided with air dispersion plate 2; The heating element heater of described heater 7 is heat-generating pipe 8.
During use, heat-generating pipe 8 is started working, under the effect of circulating fan 4, circulating hot water after heating is drawn in product oven 3 by advancing hot air duct 1, under the effect of air dispersion plate 2, thereby product is carried out homogeneous heating, cold wind after heating is again by circulating fan 4, and then filter through prefiltration net 5 and 6 pairs of circulated airs of smart screen pack successively, carry out concurrent heating by heat-generating pipe 8 more at last, then enter by advancing hot air duct 1 that product oven 3 is interior carries out homogeneous heating to product.The rest may be inferred.
When using, the utility model can be applied on manual product oven and automatic production oven on spray-painting production line simultaneously.
