Enameling machine oven
Technical field
The utility model relates to a kind of baking oven, concrete relates to a kind of enameling machine oven.
Background technology
Enameling machine oven is the important utensil that uses in the bag lacquerer order of Production of Enamel Wires, existing enamelling machine mostly adopts heat exchange principle, it is the process of ozone and electric heating exchange, and the enameling machine oven distance is shorter, affect the degree of baking and banking up with earth of enamelled wire, limited the line speed of enamelled wire, the output of enamelled wire is not increased.The heating of available technology adopting water produces the heat steam, has also brought high electric cost expenditure.
Summary of the invention
The purpose of this utility model provides a kind of enameling machine oven of energy savings.
For addressing the above problem, the technical scheme that the utility model is adopted is:
A kind of enameling machine oven, comprise casing and steam pipeline, described casing one end arranges the enamelled wire passage, on the described casing choke relief valve is set and box house arranges cavity, catalytic unit and circulating fan are set in the cavity, catalytic unit and circulating fan place have respectively heat entrance and heat outlet on the described cavity, described heat outlet is communicated with respectively the entrance and exit of enamelled wire passage by the two-way pipeline, described heat entrance is by the middle part of pipeline communication enamelled wire passage, described casing top arranges heat exchanger, the lower end of heat exchanger is communicated with cavity, the upper end arranges the waste discharge blower fan, and described steam pipeline is communicated with casing by heat exchanger.Paint on the enamelled wire enters that run into behind the baking oven behind the high temperature can evaporation, enter the catalytic unit catalytic combustion after the evaporation, then the waste gas after the burning is drained under the effect of waste discharge blower fan, the heat of catalytic combustion enters circulating fan and again enters the utilization of enamelled wire channel cycle, waste gas after the burning through over-heat-exchanger the time and in the casing fresh air through over-heat-exchanger carry out heat exchange, make fresh air become steam in order to follow-up use, heat exchange has realized taking full advantage of of energy, has saved energy resources.
As further improvement of the utility model, with on the two-way pipeline that heat outlet is communicated with inlet valve is set respectively, import is auxiliary and outlet valve, outlet are assisted.Import is auxiliary and outlet is auxiliary replenishes the heat that enters the enamelled wire passage, the size of inlet valve and outlet valve control additional heat, further energy savings.
The beneficial effects of the utility model are: realize the recycling of heat, saved energy resources, and simple in structure, easy to operate, cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Enameling machine oven as shown in Figure 1, comprise casing 1 and steam pipeline 2, described casing 1 one ends arrange enamelled wire passage 3, choke relief valve 4 is set on the described casing 1 and casing 1 inside arranges cavity 5, cavity 5 interior catalytic unit 6 and the circulating fans 7 of arranging, catalytic unit 6 and circulating fan 7 places have respectively heat entrance 8 and heat outlet 9 on the described cavity 5, described heat outlet 9 is communicated with respectively the entrance and exit of enamelled wire passage 3 by the two-way pipeline, described heat entrance 8 is by the middle part of pipeline communication enamelled wire passage 3, described casing 1 top arranges heat exchanger 10, the lower end of heat exchanger 10 is communicated with cavity 5, the upper end arranges waste discharge blower fan 11, and described steam pipeline 2 is communicated with casing 1 by heat exchanger 10.Inlet valve 12, import auxiliary 14 and outlet valve 13, outlet auxiliary 15 are set respectively on the two-way pipeline that is communicated with the heat outlet in the utility model enameling machine oven.
The circulation of heat: the paint on the enamelled wire enters that run into behind the baking oven behind the high temperature can evaporation, enter catalytic unit 6 catalytic combustions after the evaporation, heat behind the catalytic combustion by circulating fan by with the entrance and exit of the heat outlet 9 two-way pipelines that are communicated with from enamelled wire passage 3 two ends, paint with evaporation after energy reduces a little transmits to the middle part of enamelled wire passage 3, then again enters the circulation that catalytic unit 6 is realized energy from heat entrance 8.
The generation of steam: the waste gas behind the paint catalytic combustion is also with suitable energy, and by waste discharge blower fan 11 with its extraction, ozone is entered in the casing 1 by choke relief valve 4 places, then enter steam pipeline 2 by heat exchanger 10, fresh air and waste gas are simultaneously through over-heat-exchanger 10, and carry out energy exchange, and be that the fresh air temperature raises, become steam.Steam of the prior art is by electricity water to be added thermogeneticly, has increased extra power consumption, and the utility model has been saved the consumption of electric energy herein, has saved production cost.
Catalytic unit 6 in the utility model, import are auxiliary 14, outlet auxiliary 15 and other are not specifically noted is prior art, and it will not go into details herein.
