Coal hot-air rotary oven

Abstract

The invention relates to a coal-fired hot blast rotary oven which includes an oven body comprising a combustion chamber and a roast chamber, wherein, a roast support is arranged in the roast chamber. The oven is characterized in that: the oven body is also provided with heating chambers, wherein, the combustion chamber and the heating chambers are arranged at the two sides of the roast chamber; a clapboard which is provided with a circulation air hole is arranged between the combustion chamber and the roast chamber; clapboards which are provided with air went windows are arranged between the heating chambers and the roast chamber; a combustor is arranged in the combustion chamber; the combustor comprises a furnace body and a flue; the furnace body comprises a hearth, a firebar and an ash bin; the flue comprises square pipes and a radiating pipe; the two ends of the radiating pipe are connected on the pipe walls of the square pipes; the inner walls of the square pipes are fixedly connected with the clapboards; the upper end and the lower end of one square pipe are sealed and the lower end is fixedly connected on the furnace body; the lower end of the other square pipe is fixedly connected on the furnace body and communicated with the hearth and the upper end is connected with the flue; the combustion chamber is communicated with the heating chambers by vent lines. The oven has the advantages of high efficiency, energy saving, safe use and environmental protection.

Description

technical field [0001] The invention relates to an oven, in particular to a coal-fired hot air rotary oven. Background technique [0002] An oven is an appliance for baking pasta. At present, commonly used ovens include electric ovens, gas ovens and oil ovens. The above-mentioned electric oven, gas oven and fuel oven are expensive to use, have a short service life, and are poor in use safety. The existing coal-fired oven is mainly composed of a combustion chamber, a baking chamber, etc., and a baking rack is arranged in the baking chamber. Although the use cost of this coal-fired oven is relatively low, its structure is unreasonable, coal ash and coal slag pollute the environment, the baking is heated unevenly, and the heat loss is large during the baking process, which wastes energy. Contents of the invention [0003] The object of the present invention is to provide a coal-fired hot air rotary oven that is safe, efficient, energy-saving and environment-friendly, and ca...
