Multifunctional universal ring kiln

Abstract

The invention relates to a multifunction universal annular kiln. It is composed of connected kiln chamber, main flue, exhaust blower, flue entrance, gate and air exhaust conduit. Its characteristic is connecting the middle main flue with outer ring flue via the blower; extracting preheating area flue gas and feeding in outer ring underground flue; after opening the gate filling into air outlet at the bottom of the kiln chamber, the said flue gas is led to roasting zone, making black smoke secondary enter into the kiln chamber and secondary high temperature burning, releasing the heat, eliminating black fumes and reaching fully combustion effect. There are five straight-through type air ducts fan mounted at external ground of the kiln chamber, outer ring secondary air intake flue is set at external of the kiln.

Description

technical field [0001] The invention relates to a wheel kiln, which can not only adapt to the specific requirements of the primary firing process, but also adapt to the secondary firing process, and is more suitable for the multi-functional universal wheel kiln with a drying chamber for the secondary firing process. Background technique [0002] Now the wheel kiln is still the main facility for sintering bricks and tiles. Regardless of whether it is a rotary kiln for primary firing or secondary firing rotary kiln, there are problems of large smoke and heavy pollution; in terms of cooling and cooling, they all rely on opening the kiln door to cool down with cold air; in terms of adjusting the temperature difference in the kiln, adopt The method of throwing coal to make up for it. Judging from the internal combustion and ignition progress of pre-tropical adobes, the middle fire is the fastest, followed by the inner fire, and the outer fire is the worst; from the perspective o...

Regardless of whether it is a rotary kiln for primary firing or secondary firing rotary kiln, there are problems of large smoke and heavy pollution; in terms of cooling and cooling, they all rely on opening the kiln door to cool down with cold air; in terms of adjusting the temperature difference in the kiln, adopt Ways to make up for coal throwing

Judging from the internal combustion and ignition progress of pre-tropical adobes, the middle fire is the fastest, followed by the inner fire, and the outer fire is the worst; from the perspective of fire escape progress, the side fire has more coal and the progress is slow; from the perspective of the insulation belt, the outer fire cools down quickly. If the coal is not added frequently, the fire will have premature aging; from the position of the kiln, the fire at the bottom of the middle fire is greater than that at the top, and the bottom is easy to stick, or even collapse; if the sintering temperature is lowered, the top and the outside are easy to burn. lack of fire
