Problems solved by technology

For tunnel kilns that operate horizontally, the material carrying system is a very weak link; they are either very heavy (such as refractory kiln cars), or easily damaged (such as push plates), or expensive (such as roller tables or track)
Moreover, the problem of the temperature difference between the upper and lower sides of the tunnel kiln’s combustion space has not been completely resolved; for vertically operating shaft kilns, there are problems of uneven sintering of materials and materials being contaminated by fuel; for inclined operating rotary kilns, there are problems of construction and Expensive to run and difficult to maintain

Embodiment Construction

[0024] figure 1 What is described is a three-dimensional structure diagram of a "linear slide kiln". In the figure, a row of closely connected flat kiln cars (3) slides from the beginning to the end of the kiln under the action of gravity in the kiln wall slide rail (2) with a certain slope.

[0025] figure 1 Described is a three-dimensional structural schematic diagram of a box-shaped slide kiln car; the through-holes (5a) and (4a) are blocked with thin-walled refractory materials (6), so that the heat mainly passes through the through-holes and blind holes. The thin-walled refractory material on the top is passed into the box. This not only improves the heat transfer efficiency, but also reduces the weight of the slide kiln car.

[0026] Various refractory tubular components can also be used as slide kiln cars. After loading the materials into the tubes and closing their sections, they are placed one by one on the chute or slide rail in the kiln to slide down; Jointed tu...

Abstract

The invention relates to a novel kiln, in particular to a continuous kiln which is characterized in that the continuous kiln at least consists of a cylindrical kiln body and a slideway kiln car sliding mainly by gravity in the kiln body; materials are loaded on the slideway kiln car and slide with the slideway kiln car from the top end to the tail end of the kiln; the cylindrical kiln body can be a straight cylinder, a bent cylinder or an equal-diameter spiral cylinder. The slideway kiln car is plate-shaped or has the structure of a casket, a crucible or a tubular container. Through holes sealed by a thin wall refractory material and blind holes are distributed on the walls of the slideway kiln car with various shapes.

Description

technical field [0001] The present invention relates to an industrial kiln, especially a continuous kiln and its construction method and application. Background technique [0002] At present, various continuous kilns used in industry mainly include tunnel kiln running horizontally, shaft kiln running vertically and rotary kiln running inclinedly. For tunnel kilns that operate horizontally, the material carrying system is a very weak link; they are either very heavy (such as refractory kiln cars), or easily damaged (such as push plates), or expensive (such as roller tables or track). Moreover, the problem of the temperature difference between the upper and lower sides of the tunnel kiln’s combustion space has not been completely resolved; for vertically operating shaft kilns, there are problems of uneven sintering of materials and materials being contaminated by fuel; for inclined operating rotary kilns, there are problems of construction and Expensive to run and difficult ...
