Abstract

The invention discloses a novel rotary kiln which comprises a kiln body and a kiln car. The kiln body is of an annular structure integrally, the kiln car is provided with a drying section, a preheating section, a high-temperature calcining section and a cooling section, the kiln body integrally falls into the ground to form a trench-type structure, an air suction passage is formed on two side faces or at the bottom of the cooling section of the kiln body, a passage is formed below the bottom of the kiln body to form a main flue, an air feeding flue is formed on two side faces or at the bottom of each of the cooling section and the drying section, and the main flue is communicated with the air suction flue and the air feeding flues. Waste heat of finished brick products and hot air are extracted from the side faces of the cooling section of the trench-type rotary kiln to enter the main flue at the bottom, and are divided to enter the air feeding passages after reaching the drying section, and the air feeding flues feed hot air from the side face of the kiln body into the drying section in the kiln body to dry wet blank bricks.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a rotary kiln with a trench structure. Background technique [0002] Today, with the rapid development of the sintered brick and tile industry, new processes, new technologies, and new equipment are used more and more in the production process, which not only greatly improves the mechanization and automation of the production line, but also brings great benefits to the production management of enterprises. The big changes have improved the working environment of workers, reduced the labor intensity of production practitioners, and raised the quality of products produced to a higher level. [0003] The main kiln types of the current brick and tile kiln mainly include rotary kiln and tunnel kiln; the tunnel kiln burns bricks in a straight tunnel where the bottom plate of the kiln moves. Its advantage is a high degree of mechanization, and its disadvantages are small output, large investment and mai...
