Abstract

一种采用风道保温增效的热风炉,包含有进风口,炉体,电热丝,出风口,炉体(2)的一端开设有进风口(1),炉体内设置有外风道(5)和内风道(6),在炉腔内装设有电热丝(3),炉体的另一端为出风口(4)。采用内、外风道设计,既能起到保温作用,又能预加热冷空气,从而提高了热风炉的热效率,降耗作用明显。

Description

一种热风炉
技术领域
本发明提供一种热风炉,具体地是一种电热式热风炉。
背景技术
热风炉是一种常用的生产设备,通常有两种加热方式,一种是燃烧加热方式,另一种是电热加热方式,这类技术目前申请了国家专利的也很多,如申请号为95116519.4的“全热管热风炉及其热风系统”和申请号为201010162709.3的“管接式高温热风炉”即是代表。
这类技术的要求主要是提高效率,降低能耗,方便快捷,因此,其技术开发均在不断的发展中,新的方式也在不断涌现。
本发明结合保温和降耗思路,开发出更具节能效果的热风炉。
发明内容
本发明的目的就是提供一种采用风道保温增效的热风炉。
实现本发明的技术方案是这样的:热风炉结构为炉体2的一端开设有进风口1,炉体内设置有外风道5和内风道6,在炉腔内装设有电热丝3,炉体的另一端为出风口4。
本发明的有益效果在于:采用内、外风道设计,既能起到保温作用,又能预加热冷空气,从而提高了热风炉的热效率,降耗作用明显。
附图说明
图1是本发明的结构示意剖面主视图。
图中,1是进风口、2是炉体、3是电热丝、4是出风口、5是外风道、6是内风道。
具体实施方式
下面结合附图对本发明的具体实施方式说明如下:
实施例:热风炉
具体结构为炉体2的一端开设有进风口1,炉体内设置有外风道5和内风道6,在炉腔内装设有电热丝3,炉体的另一端为出风口4。
冷风沿热风炉外层到达出口端,折返通过中间层,到达进口端,折返穿过设有电热丝的热风炉内层,进一步加热后从出风口端送出,供干燥器使用。
