The invention discloses an air return type energy saving annular kiln for producing a shale brick and a production method. The air return type energy saving annular kiln comprises a kiln channel, a main flue and a draft fan. An outer fume exhaust hole is arranged at the lower part of the outer side wall of the kiln channel, and an air return flue is arranged at the outer side of the kiln channel and is communicated with the main flue through a fume exhaust channel; the draft fan is arranged at the connecting part of the air return flue and the fume exhaust channel; and the outer fume exhaust hole is communicated with the air return flue through an air return branch flue, and an air return air brake is arranged at the connecting part of the air return branch flue and the air return flue. In the invention, high temperature fume after roasting is sent into a drying region of the kiln channel through the air return branch flue so as to dry a green brick by utilizing the air return flue and is cyclically utilized in the annular kiln by controlling various air brakes, thereby enhancing the utilization ratio of the high temperature fume, efficiently saving the energy, also realizing continuous drying, preheating and roasting, greatly enhancing the production efficiency and enhancing the yield by above 2 times.
Description
technical field [0001] The invention relates to a return air type energy-saving wheel kiln for shale brick production and a production method. Background technique [0002] The wheel kiln, also known as the ring kiln, is a continuous kiln for the production of bricks and tiles. Generally speaking, the wheel kiln has a continuous annular kiln road, the straight section is the straight kiln section, and the semi-circular arc section is the curved kiln section. There is no transverse partition wall in the kiln road, and a kiln door is set at a certain distance on the outer wall of the kiln road for loading bricks or finished bricks. The corresponding section between two adjacent kiln doors is called a kiln chamber. There is a smoke exhaust hole on the side wall of the kiln chamber between the kiln doors, also known as Hafeng. There is a main flue between two parallel kilns along the length of the kiln. It is connected by the branch flue, and the junction of the branch flue an...
