Wide roller kiln for burnt porcelain brick

Abstract

The invention discloses a broad roller kiln for a burnt porcelain brick, which comprises a kiln furnace burning nozzle and a burning assistant (or atomizing) blower. The kiln furnace burning nozzle is divided into a remote burning nozzle with reducing tube gradient and a near burning nozzle with increasing tube gradient; the burning assistant (or atomizing) blower is divided into a remote burning assistant (or atomizing) blower and a near burning assistant (or atomizing) blower; the burning nozzle brick of the kiln furnace burning nozzle has different gradient cone heights; the remote burning nozzle with different gradient cone heights and the reducing tube gradient is matched with the near burning nozzle with increasing tube gradient for use; and the kiln furnace burning nozzle brick has different inlet and outlet diameters, and the furnace kiln burning nozzles with different inlet and outlet diameters are matched with each other for use. Through the match of the adjustment means, a plurality of spraying coverage can be obtained within the cross section of the kiln furnace, so that kiln furnace has the capacity of isothermal control of the cross sections.

Description

technical field [0001] The invention relates to a roller kiln. Especially wide-body roller kilns for the production of fired porcelain tiles. Background technique [0002] At present, the most popular roller kiln for firing porcelain tiles with an inner width of about 2.5 meters in many ceramic factories has been extended to 320 meters in length. . As the length of the kiln increases, the heat dissipation area of ​​the kiln increases, which increases the cost of insulation materials and increases the consumption of fuel. As the length of the kiln increases, the power of the kiln fan also increases, which increases the power consumption. The above-mentioned shortcomings can be overcome by using a wide-body kiln, but the roller kiln with a cross-sectional width exceeding 2.6 meters has the problem of temperature difference on the cross-section. Foreign kiln companies mainly start with pulse control technology. The basis of this technology is: according to actual needs, the...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the deficiency that the roller kiln cross section width exceeds 2.6 meters in the prior art, which cannot effectively control and eliminate the deficiency of the cross section temperature difference of the roller kiln, and provides a kiln with a cross section width of 3.2 meters, which can effectively Wide Body Roller Kiln for Production of Fired Porcelain Bricks by Controlling and Eliminating Temperature Differences in Cross Section of Roller Kiln
