Abstract

The utility model provides an energy-saving brick which is a fan-shaped block. The energy-saving brick is formed by a heavy wear-resistant layer at a small end and a light heat-insulating layer at a big end into a whole. The energy-saving brick has a thickness of 98 mm and a fan-shaped angle of 6.53 degrees, and the radius of excircle of the light heat-insulating layer is 2,000 mm. The energy-saving brick is characterized in that the radial length of the light heat-insulating layer is 140-180 mm, the total radial length of the heavy wear-resistant layer and the light heat-insulating layer is 300-350mm, and lapping grooves are arranged at the two ends of the fan-shaped block. The service life of the energy-saving brick reaches up to more than two years.

Description

A kind of energy-conservation brick

Technical field

The utility model relates to a kind of energy-conservation brick, is particularly suitable for building by laying bricks or stones rotary kiln.

Background technology

At present, the gross thickness of inner liner of rotary kiln refractory material is at 230mm, and wherein the lightweight heat-proof layer thickness is about 60mm, because thermal insulation layer thickness is thin partially, the kliner coating temperature can only be controlled at below 300 ℃.Though can satisfy instructions for use,, be unfavorable for energy-saving and cost-reducing and reduction of discharging because kliner coating temperature height causes the hear rate height.

Summary of the invention:

In order to overcome the shortcoming of prior art, the utility model provides a kind of energy-saving brick, and it can make the kliner coating temperature be controlled at below 200 ℃, and is energy-saving and cost-reducing, reduces production costs.

The technical scheme in the invention for solving the technical problem is: it is a secter pat, consist of one by the heavy wearing layer of small end and the light heat insulation layer of big end, its thickness is 98 millimeters, segment angle is 6.53 degree, the radius of light heat insulation layer cylindrical is 2000 millimeters, it is characterized in that: described light heat insulation layer length radially is 140～180 millimeters, and heavy wearing layer and light heat insulation layer total length radially is 300～350 millimeters; The two ends of the described secter pat groove of helping to shoulder heavy thing.

The utility model is owing to increased the thickness of lining refractories thermal insulation layer, so the kliner coating temperature is controlled at below 200 ℃, the rotary kiln hear rate descends 20%.Energy-saving and cost-reducing on the one hand, reduced producing, on the other hand because hear rate reduces, and inevitable Fuel Consumption reduces, thereby make the combustion product gases discharging reduce, can play the effect of energy-saving and emission-reduction.
