Embodiment Construction

[0010] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0011] Fig. 1-Fig. 2 is the preferred scheme of the present invention, has shown the connected kiln chamber, total flue 32, exhaust fan 22, Kazakhstan outlet 10 and 11, gate, and the composition of exhaust duct, is characterized in that: connects the middle with exhaust fan 1 The total flue 32 and the outer ring flue 5 extract heat from the pretropical flue gas and enter the outer ring underground flue 6. After opening the gate, it is injected into the air outlet 7 at the bottom of the kiln chamber, and the flue gas is introduced into the roasting zone to make the black smoke After entering the kiln chamber for the second time, the high-temperature secondary combustion releases heat, eliminates black smoke, and achieves the effect of full combustion. Use the exhaust fan to connect the upper air duct and the lower air duct, extract the waste heat after roasting and tra...

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...
