具体实施方式Detailed ways
下面通过附图对本发明技术方案进行详细说明，但是本发明的保护范围不局限于所述实施例。The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.
实施例1：一种热风循环烘箱，如图1、2所示，包括箱体1、设置于箱体1两侧的出风风道和设置于所述箱体1内部的层级烘架，所述箱体1两侧的出风风道里设置加热管。Embodiment 1: A hot air circulation oven, as shown in Figures 1 and 2, includes a box body 1, air outlet ducts arranged on both sides of the box body 1, and layered drying racks arranged inside the box body 1. Heating pipes are arranged in the air outlet ducts on both sides of the casing 1.
本实施例中，箱体1的顶部设置风机2，所述风机2为长轴式轴流风机，轴流式风机通常应用在通风换气的场所，而本实施例中采用长轴式轴流风机，通过对风机旋转轴的加长设计，增大了风机与加热管之间的距离，避免了温度过高影响风机的工作。In this embodiment, a fan 2 is installed on the top of the box body 1, and the fan 2 is a long-axis axial flow fan. The axial flow fan is usually used in a place for ventilation, and the long-axis axial flow The fan, through the lengthening design of the fan rotation shaft, increases the distance between the fan and the heating pipe, avoiding the work of the fan being affected by the high temperature.
