Round underground heat-insulating brick kiln

Abstract

A round underground heat-insulating brick kiln comprises a round main kiln cavity with an opening at the top. The main kiln cavity is positioned underground, a cover plate is arranged at the top of the main kiln cavity, a pair of parallel guide rails are arranged at the opening of the top of the main kiln cavity, the cover plate can move along the guide rails to enable the top of the kiln cavity to be closed or opened, a heat-insulating layer is arranged in the cover plate, and a material and personnel passage is formed on the side wall of the kiln cavity; a burning area is arranged in the middle of the main kiln cavity, and a smoke hole corresponding to the burning area in position is formed in the cover plate. By adopting the round underground heat-insulating brick kiln, fuel heat utilization efficiency and one-time firing number are increased; vertical excavation and the top movable cover plate are adopted, so that earthwork load of the brick kiln is reduced; in order to substantially improve heat-insulating performance in the side wall direction of the kiln cavity, the top movable cover plate can be completely opened when ventilation and air feeding are needed, so that convenience is brought to quick cooling inside the kiln cavity and completion of fresh air exchange, and personnel is avoided being scalded or injured due to inhaling of toxic waste gas.

Description

technical field [0001] The invention belongs to the field of construction, and relates to an earthen kiln for firing bricks, in particular to a circular underground thermal insulation brick kiln. Background technique [0002] A brick kiln is a building composed of multiple brick-burning cave dwellings and chimneys. When firing bricks, the temperature in the cave is quite high, about thousands of degrees. The main location of the kiln is above the cave dwelling, and the earth bricks are placed inside the cave dwelling. [0003] Existing brick kiln chambers are annular, with multiple doors equally spaced around them, which can be considered to be composed of a plurality of interconnected kiln chambers, which share a chimney in the middle. After the wheel kiln is ignited, the fire head burns from one kiln chamber to another, and flows between the ring-shaped kiln chambers. After the fire head passes, the bricks are burnt. After the air is blown to cool down, the burnt bricks ...

AI Technical Summary

Problems solved by technology

However, most of the existing brick kilns are built by underground side excavation. The entry and exit of personnel and materials depend on the kiln mouth. It is easy to be burned or inhaled toxic residual exhaust gas to cause personal injury. At the same time, digging underground sideways to build a brick kiln requires a lot of work. The volume of the brick kiln is small, and the amount of bricks fired at a time is small.
