Turnover kiln with air distribution system arranged at bottom

Abstract

The invention provides a turnover kiln with an air distribution system arranged at the bottom. The air distribution system is composed of a kiln body annular interior wall, annular heat suction main air ducts, heat suction branch air ducts, an annular heat sending main air duct, heat sending branch air ducts, moisture discharge openings and a heat sending draught fan desulfuration and dust removing device. By means of opening of a plurality of air brakes fixedly distributed in the heat suction main air ducts and the heat sending main air duct and by means of reasonable joining of air used for drying and roasting in a kiln furnace moving on the annular bottom of the kiln, waste heat can be fully utilized, the aim of conducting artificial drying and one-time palletizing and burning can be achieved, and therefore kiln loading and kiln discharging can be conducted outside the kiln. The air distribution system can thoroughly solve the difficult problem of high-temperature corrosion resistance of the kiln body steel structure and can scientifically and efficiently conduct desulfuration and dust removing, the primer can more easily enter the bottom of the kiln, positive-pressure moisture discharge is achieved, green bodies can be rapidly and evenly dried, unnecessary intermediate process links and devices are omitted, the diameter of the kiln can be large or small, and the turnover kiln is more suitable for small-scale investment and plant construction. The turnover kiln can be specially used for sintering non-bearing air bricks when the diameter of the kiln is small, one and a half times of palletizing and burning can be achieved through natural drying bricks when the diameter of the kiln is large, and the turnover kiln is also suitable for automatic kiln stacking conducted through mechanical hands.

Description

technical field [0001] The invention relates to a tunnel kiln for sintering bricks, in particular to a turnover tunnel kiln with an air distribution system. Background technique [0002] The traditional brick-making process uses fixed wheel kilns or tunnel kilns to burn bricks. Due to backward production technology, serious environmental pollution, labor-intensive workers, and high production costs, this kind of kiln has been gradually eliminated. Chinese patent 200610048330.3 discloses a mobile tunnel kiln. By arranging traveling wheels on both sides of the tunnel kiln body, the mobile tunnel kiln can sinter bricks into bricks during the moving process. The kiln body of this kind of mobile tunnel kiln is made of steel frame structure and insulation materials, and the cost is very low, only about two-thirds of the cost of tunnel kilns of the same scale. The number of workers is reduced, and the labor cost is greatly reduced. The air distribution system of the mobile tunnel...
