Large-section multi-split type energy-saving tunnel kiln

Abstract

The invention discloses a large-section multi-split type energy-saving tunnel kiln. The large-section multi-split type energy-saving tunnel kiln comprises a kiln wall foundation, side kiln walls, a kiln top and kiln cars, wherein the kiln top is connected with the two side kiln walls arranged in parallel, the at least two kiln cars are arranged between the two side kiln walls, and the kiln cars are of a symmetrical structure with the center line parallel to the side kiln walls as the symmetry axis. By enlarging the section of the kiln, not enlarging kiln cars and adopting a parallel multi-kiln-car mode, the two or more kiln cars are arranged in the tunnel kiln in parallel, the kiln cars are independent of one another, and synchronous car entering and asynchronous car entering can be achieved; the two sides of the kiln cars are symmetrically designed, so that the universality of the kiln cars in all lanes is ensured, and the misoperation risk is reduced; the yield of the kiln is increased, the occupied area of kiln construction is reduced, and the kiln construction cost is reduced, so that direct increase of high investment cost of a kiln production line and increase of the occupied space are avoided; and meanwhile, the problems of overlarge kiln cars and high equipment operation and maintenance cost caused by directly enlarging the section of the kiln and enlarging the kiln cars are solved.

Description

technical field [0001] The invention relates to the technical field of tunnel kilns, in particular to a multi-section energy-saving tunnel kiln with large sections. Background technique [0002] The tunnel kiln is a kiln similar to a tunnel, which is built of refractory materials, thermal insulation materials and building materials, and is equipped with kiln cars and other vehicles. It is a modern thermal equipment for continuous firing. Tunnel kilns are widely used in the roasting production of ceramic products, and are also used in metallurgical industries such as abrasives. [0003] In the prior art, tunnel kilns with small cross-sections and large kiln cars and tunnel kilns with large cross-sections are mostly used. The tunnel kilns with small cross-sections and multiple kilns directly increase the kiln production line and parallel multiple tunnel kilns; tunnel kilns with large cross-sections and large kiln cars It is to directly increase the section of the kiln and enl...

AI Technical Summary

Problems solved by technology

Directly increasing the kiln production line will greatly increase the investment cost and occupy more space. At the same time, increasing the kiln will increase the heat loss of the kiln wall and increase the cost of fuel use; directly increase the kiln section and increase the kiln car, resulting in the kiln car being too large and difficult to operate. It is difficult to use and maintain, and it leads to an increase in the model of the operating equipment, an increase in investment costs, and makes the operation of the operating equipment difficult, poor in operation reliability, easy to damage the equipment, increased maintenance costs in the later period, heavy workload, and high management requirements.
