Detailed Description
The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.
Example (b):
as shown in fig. 1, the embodiment provides a straight-through powder curing oven, which includes an oven 1 and a heating system, wherein the heating system is disposed at a side of the oven 1; oven 1 is the cuboid form in this scheme, and the work piece is arranged in oven 1 and is cured the stoving, and this scheme sets up heating system in oven 1's side, rather than arranging oven 1 top in, so just reduced the whole height of curing oven for some shorter factory buildings are suitable for equally.
In this embodiment, the heating system includes a heating chamber 21 disposed at the side of the oven 1, two circulating fans 22 disposed at two sides of the heating chamber 21, and two filters 24 disposed in the heating chamber 21; the filter 24 may be a conventional corrugated high temperature resistant filter 24, and the filter 24 has a high temperature resistant effect and can operate in a high temperature environment, and thus may be preferably used.
The heat exchange chamber 23 is formed between the two filters 24 at intervals, the heat exchanger 25 connected with a burner (not shown in the figure) is arranged in the heat exchange chamber 23, when the heat exchanger works, the burner burns to generate hot air, then the hot air is led into the heat exchanger 25 (the heat exchanger 25 can adopt a 70 ten thousand heat exchanger 25), and at the moment, when the air blown by the circulating fan 22 passes through the heat exchanger 25, the air can exchange heat with the hot air in the heat exchanger 25 to form hot air. In this embodiment, the burner can be independently installed outside the curing furnace, or a space can be separately defined in the heating chamber 21 for installing the burner, and the specific manner can be selected according to actual needs.
Referring to fig. 3, an air inlet end of the circulating fan 22 is communicated with the oven 1, and an air outlet end of the circulating fan faces the filter 24 to blow air into the heat exchange chamber 23; and an air return opening 28 communicated with the oven 1 is arranged on the heat exchange chamber 23.
When the air conditioner works, the circulating fan 22 extracts air in the oven 1 and discharges the air to one side of the filter 24, the air is filtered by the filter 24 to filter part of dust mixed in air flow, and then the air enters the heat exchange chamber 23 and the heat exchanger 25 in the heat exchange chamber 23 to realize heat exchange to form hot air; hot air flows back from the air return opening 28 and enters the oven 1 to cure and dry the workpiece in the oven 1, then the hot air in the oven 1 is extracted by the circulating fan 22 again to continue repeating the steps, and the steps are repeated in a circulating manner to form a hot air internal circulation system, so that the temperature in the oven 1 is balanced, and a better curing and drying effect is achieved.
Referring to fig. 1 and 2, in the present embodiment, two sealing plates 26 are disposed in the heat exchange chamber 23, and the two sealing plates 26 are spaced apart from each other to form a heat exchange area; the heat exchanger 25 is arranged in a heat exchange area, and when the heat exchanger is specifically installed, the two sealing plates 26 seal the spaces on two sides of the heat exchanger 25, so that the heat exchanger 25 divides the heat exchange area into an upper part and a lower part, and airflow flows from bottom to top in the heat exchange area. It will be seen that the two closure plates 26 are arranged to compress the flow area of the air stream so that the air blown by the circulator 22 largely exchanges heat across the heat exchanger 25.
The bottom of the sealing plate 26 is provided with an air inlet 241, air blown out by the circulating fan 22 enters a heat exchange area from the air inlet 241, and the air inlet 241 is positioned below the heat exchanger 25, so that the air entering the heat exchange area flows from bottom to top and exchanges heat when passing through the heat exchanger 25; the air return opening 28 is arranged in the heat exchange area and above the heat exchanger 25, so that the hot air heated by the heat exchanger 25 returns to the oven 1 from the air return opening 28.
In the heat exchange area, an inclined air deflector 27 is arranged at the position of the air return opening 28, the air deflector 27 can guide air flow (namely hot air), and when the air flow impacts the air deflector 27, the air deflector 27 is inclined, so that the air flow can be folded back to one side of the air return opening 28 and directly enters the air return opening 28.
Because a part of waste gas generated by drying can be reserved in the oven 1 after the oven is used, and after workers enter the oven 1, the workers breathe the waste gas, which undoubtedly affects the health, in the embodiment, the oven 1 is also provided with an exhaust system; the exhaust system comprises an exhaust fan 32 arranged on the oven 1; the air inlet end of the exhaust fan 32 is communicated with the inside of the oven 1 through an exhaust pipe 31; an exhaust pipe 33 is arranged at the air outlet end of the exhaust fan 32, and the exhaust pipe 33 directly extends out of the plant; a valve (not shown in the figure for reasons of view) is arranged on the exhaust pipe 31. Therefore, before entering the oven 1, the worker can open the valve and the exhaust fan 32, utilize the exhaust fan 32 to draw the air in the oven 1, and exhaust the air through the exhaust pipe 33, so as to reduce the exhaust gas content in the oven 1, the whole exhaust process of the exhaust fan 32 is kept for at least 15min, in other words, the worker preferably enters the oven 1 to operate after the exhaust fan 32 exhausts for 15 min. When curing operation of oven 1 is required, valves and blower 32 are closed.
A shield (not shown) is arranged at one end of the exhaust duct 33 far away from the exhaust fan 32, wherein the shield can be a hood or a baffle directly shielding the end of the exhaust duct 33, and the main function of the shield is to prevent rainwater from entering the exhaust duct 33 in rainy days.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the present invention.
