Novel energy-saving kiln

Abstract

The invention discloses a novel energy-saving kiln. The novel energy-saving kiln comprises a kiln wall body, burner supports are arranged in the kiln wall body at equal distances, burners for sprayingfire into the interior of a kiln body are arranged on the burner supports, polycrystalline cotton layers are arranged at one ends, facing the interior of the kiln, of the burner supports, zircon-containing cotton layers and common asbestos layers are sequentially arranged at one ends, far away from the interior of the kiln, of the burner supports, the upper end of the kiln wall body is provided with a kiln roof, the top of the kiln roof is sequentially provided with a polycrystalline cotton layer, a ceiling framework, a zircon-containing cotton layer and a common asbestos layer from bottom totop, a kiln car running in the length direction of the kiln body is arranged in the kiln, the upper surface of the kiln car is sequentially provided with the common asbestos layer, the zircon-containing cotton layer and the polycrystalline cotton layer. According to the novel energy-saving kiln, the burner supports are installed in an asbestos wall body, an air curtain sealing technology is adopted on the contact surface between a wall body of a sintering belt and the kiln car, the technical problem encountered in the installation of the whole asbestos kiln body is solved, and the energy-saving level of the kiln is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ceramic kilns, in particular to a novel energy-saving kiln. Background technique [0002] Tunnel kiln firing products industry The construction of high-temperature firing kilns is to build high-temperature-resistant bricks and then paste high-temperature cotton on the wall of the kiln body. Burning guns are arranged up and down on both sides of the kiln body to fire products. Brick is the main load and heat insulation material of the kiln body. The method of using high-temperature resistant brick kilns generally has a long construction period (120 days), low heat energy utilization efficiency, and high firing costs (accounting for more than 35% of the total cost). Poor product quality and high cost of building kilns. [0003] According to the comparison of the performance of heat-resistant materials at present, the heat-resistant and heat-insulating performance of asbestos is 35-40% higher than that of h...

AI Technical Summary

Problems solved by technology

In the firing of existing tunnel kilns, in order to achieve the same upper and lower temperatures, burners are arranged on the upper and lower sides of the kiln body to make the upper and lower temperatures of the kiln body consistent. If asbestos is used to replace high-temperature heat-resistant bricks as walls to reduce e
