Abstract

The utility model discloses a composite brick for rotary kiln, composite brick that forms including front end heavy matter brick and rear end light brick complex, along composite brick's fore-and-aft direction, heavy matter brick accounts for three fourths of total length, and light brick accounts for the fourth of total length, and from rear end light brick to front end heavy matter brick, composite brick's width gradual change is dwindled and is made a plurality of composite bricks can make up for the annular. The joint of the light brick and the heavy brick is positioned on two surfaces of the composite brick, one is provided with a bulge, and the other is provided with a groove matched with the bulge. Adopt the utility model discloses a design, replaced current rotary kiln heavy matter brick and the independent setting of light brick, influenced holistic stability and caused the problem of wasting of resources after heavy matter brick has worn and torn two-thirds.

Description

Composite brick for rotary kiln

Technical Field

The utility model relates to a rotary kiln field, concretely relates to composite brick for rotary kiln.

Background

The brick blocks adopted by the existing rotary kiln are the combination of heavy bricks and light bricks which are independent components, the common design mode is that the heavy bricks are spliced into a ring shape by grinding, and a circle of light bricks are arranged on the periphery of the heavy bricks.

Disclosure of Invention

The purpose of the invention is as follows: the utility model aims to solve the independent setting of present fragment of brick for the rotary kiln, lead to the unstable problem of overall structure when heavy weight brick wearing and tearing reach two-thirds.

The technical scheme is as follows: in order to achieve the above object, the utility model provides a following technical scheme:

a composite brick for a rotary kiln comprises a composite brick formed by compounding a front heavy brick and a rear light brick, wherein the heavy brick occupies three quarters of the total length and the light brick occupies one quarter of the total length along the front and rear directions of the composite brick, and the width of the composite brick is gradually reduced from the rear light brick to the front heavy brick, so that a plurality of composite bricks can be combined into a ring shape.

Furthermore, the joint of the light brick and the heavy brick is positioned on two surfaces of the composite brick, one is provided with a bulge, and the other is provided with a groove matched with the bulge.

The adjacent composite bricks can be stacked without mutual sliding.

Furthermore, zigzag connection which is mutually matched is respectively designed at the joint of the light bricks and the heavy bricks.

And the mutually matched saw-tooth design is adopted, so that the mutual combination is tighter after sintering.

Further, the heavy brick is a heavy brick with a higher sintering temperature.

Further, the light brick is a light brick with a low sintering temperature.

Further, the heavy brick and the light brick are integrally formed.

The design of integrated molding is adopted, so that the gravity centers of the light bricks and the heavy bricks are integrated into one point and are close to one side of the light bricks.

Has the advantages that: compared with the prior art, the utility model: adopt the utility model discloses a design, replaced current rotary kiln heavy matter brick and the independent setting of light brick, influenced holistic stability and caused the problem of wasting of resources after heavy matter brick has worn and torn two-thirds.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.

Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

Example 1

As shown in fig. 1, a composite brick for a rotary kiln comprises a composite brick formed by combining a front heavy brick 1 and a rear light brick 2, wherein the heavy brick 1 occupies three quarters of the total length and the light brick 2 occupies one quarter of the total length along the front and rear directions of the composite brick, and the width of the composite brick is gradually reduced from the rear light brick to the front heavy brick 1, so that a plurality of composite bricks can be combined into a ring shape.

The joint of the light brick 2 and the heavy brick 1 is positioned on two surfaces of the composite brick, one is provided with a bulge 3, and the other is provided with a groove 4 matched with the bulge.

The adjacent composite bricks can be stacked without mutual sliding.

The light bricks 2 and the heavy bricks 1 are respectively designed with mutually matched sawteeth 5 for connection.

The heavy brick 1 is a heavy brick with higher sintering temperature.

The light brick 2 is a light brick with lower sintering temperature.

The heavy brick 1 and the light brick 2 are integrally formed.

Example 2

As shown in fig. 2, based on embodiment 1, the light brick 2 is designed to have a downward back hook extension, which can hook the edge of the rotary kiln 7 to prevent the structure from collapsing under the condition of unstable center of gravity.
