Abstract
The invention relates to a tunnel kiln which comprises an upper kiln body, a lower kiln body, an air inlet, an air outlet and a fan. The upper kiln body is joined with the lower kiln body through bolts, the upper kiln body and the lower kiln body are both hollow, the hollow portions are filled with asbestos heat insulation materials, a resistive heater or a heating plate is arranged inside the tunnel kiln, the air outlet is formed in the upper portion of the upper kiln body, the air inlet is formed in the lower portion of the lower kiln body, an outlet of the fan is connected with the air inlet, and the fan is installed on a fan frame.
Description
Technical field
The invention belongs to heater, particularly relate to a kind of continuous tunnel furnace that utilizes hot air circulation to heat.
Background technology
High temperature tunnel furnace need to ensure certain sintering temperature in the time of sintered products, and heating must be evenly, guarantee sintering quality, although common baking oven or heating furnace firing rate are fast, but heat inhomogeneously, sintering quality is low, easily occurs product quality problem.
Summary of the invention
The problem that prior art is existed, the logical object of the present invention is to provide a kind of high temperature tunnel furnace, reaches the object of homogeneous heating by heated air circulation device.
For achieving the above object, the technical solution used in the present invention is: a kind of continuous tunnel furnace, comprise upper furnace body, lower furnace body, air inlet, air outlet, and blower fan.
Upper and lower furnace binding is designed to the form of the cotton insulation material of horsestone between two-layer template.Upper and lower body of heater skin and internal layer all adopt 5mm cold-rolled steel sheet, and punch forming, is mingled with insulation material therein.Employing bolted on connection between upper lower furnace body.
Inner electrical heating wire or the heating plate installed of body of heater.
The invention has the beneficial effects as follows:
Because the present invention adopts electrical heating wire or heating plate energising heating, heat energy transfers to rapidly body of heater inside, and fan starting is upwards carried along body of heater inside, forms high-temperature hot-air, thereby reaches sintering temperature, completes the sintering process of relative article.
