Description

Technical Field

[0001] The present invention relates to the technical field of calcining furnaces, and in particular to a calcining furnace with a feed anti-blocking function. Background Technology

[0002] Calcining furnace is a thermal equipment that heat treats carbon raw materials (such as coke, anthracite, etc.) at high temperature to improve the performance of raw materials. In order to prevent blockage at the feed point, existing calcining furnaces usually pre-crush the materials to reduce subsequent feed blockage and keep production going smoothly.

[0003] For example, a calcining furnace with good anti-blocking effect for metal smelting engineering with announcement number CN219433794U includes a bottom plate, the top of the bottom plate is fixedly connected to the calcining furnace body, both sides of the top of the calcining furnace body are fixedly connected to a shell, the top of the shell is fixedly connected to a material box, the bottom of the material box is connected to the calcining furnace body with a drop pipe, the back of the shell cavity is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a cam, and the inner wall of the shell is fixedly connected to a telescopic rod, which solves the existing The anti-clogging effect of the calcining furnace used in technical metal smelting engineering is poor, which can easily cause the material to adhere to the inner wall of the discharge pipe and cause blockage. However, after the device crushes the material, it directly discharges the material through the discharge pipe. There will be some large pieces of material that are not completely crushed. These large pieces of material may still cause blockage at the feed port, which also reduces the subsequent calcination effect of the calcining furnace. In addition, the material adhesion to the inner wall of the discharge pipe is reduced only by knocking. For some tightly adhered materials, it is difficult to clean them completely, which limits the feeding.
