Heat energy recycling structure of building brick kiln

Abstract

The invention provides a heat energy recycling structure of a building brick kiln. The heat energy recycling structure of the building brick kiln comprises a first hot air pipe, a second hot air pipe and a third hot air pipe; an air inlet of the first hot air pipe is formed in a cooling section of a kiln body, and while an air outlet of the first hot air pipe is formed in a forced moisture eliminating chamber of the kiln body, wherein the forced moisture eliminating chamber is positioned at the tail part of a drying section of the kiln body and is formed by a space isolated between two lifting doors of an inner cavity of the drying section; the second hot air pipe and the third hot air pipe are arranged in parallel; the air inlet of the second hot air pipe and the air inlet of the third hot air pipe are both formed in the front part of a preheating section of the kiln body; the air outlets of the second hot air pipe and the third hot air pipe are formed in the whole drying section of the kiln body, besides the forced moisture eliminating chamber; air blowers are mounted at the front parts of the first hot air pipe, the second hot air pipe and the third hot air pipe. With the adoption of the heat energy recycling structure of the building brick kiln, a green brick can be fully and uniformly dried before being roasted, so that the brick quality can be improved, the heat energy is fully utilized, and as a result, the energy is saved, and the consumption is decreased.

Description

technical field [0001] The invention relates to equipment for firing building bricks, in particular to a heat energy recycling structure for a kiln for firing building bricks. Background technique [0002] The mobile tunnel kiln is a new type of kiln equipment that does not move the kiln bottom and the kiln body moves. Filled with refractory and heat-insulating aggregates, the kiln body as a whole is an arc-shaped tunnel-shaped box concentric with the kiln bottom and the circular track. Steel is used as the main frame, and the inner wall is made of fiber or light-weight heat-insulating bricks for heat insulation. The fireproof layer, the kiln body is to the circular track what the train is to the railroad track, the brick stacks are placed in the stacking area between the two circular track, and the kiln body moves once every time the fire advances a stack. [0003] Existing mobile tunnel kilns usually only have one set of suction air ducts, which extract the waste heat fro...

AI Technical Summary

Problems solved by technology

This structure is not conducive to the sufficient and uniform drying of the adobe, so that the water content of the adobe when it is fired is relatively large and uneven, and the bottom and middle of the adobe stack contain too much water, and the quality of the finished bricks obtained after roasting is uneven. The problem of brick pile collapse is prone to occur
