Refractory brick for boiler masonry

Abstract

The invention relates to the technical field of refractory bricks, in particular to a refractory brick for boiler masonry. A clamping block is arranged in the middle of the upper surface of the brick body; a clamping groove is formed in the middle of the lower surface of the brick body; a rotating mechanism is arranged at the position, corresponding to the clamping block, of the upper surface of the brick body and comprises a containing groove formed in the position, corresponding to the clamping block, of the upper surface of the brick body. Two fixing rings are symmetrically and fixedly connected to the positions, corresponding to the clamping blocks, of the side wall of the containing groove. A rotating shaft is arranged between the two fixing rings; the outer circle face, located between the two fixing rings, of the rotating shaft is sleeved with a sleeve. The upper end of the outer circle face of the sleeve is fixedly connected with a connecting block. The influence of collision between bricks caused by bumping of a transport vehicle on the clamping blocks can be reduced, the situation that cracks or fractures occur at the joints of the clamping blocks and the brick bodies is reduced, the influence on follow-up refractory brick masonry is reduced, and the refractory brick masonry efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of refractory bricks, in particular to a refractory brick for boiler masonry. Background technique [0002] Refractory brick, referred to as fire brick, is a refractory material fired from refractory clay or other refractory raw materials. High temperature resistant materials for kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures. [0003] When the existing refractory bricks for boiler masonry are used, it is first necessary to mix the refractory powder with water in proportion to form refractory mud, use tools to apply the refractory mud to the outer surface of the refractory bricks, and use the strut method or the arch method to install the refractory mortar. Masonry is carried out on the surface of the inner cavity of the boiler. [0004] The existing refractory bricks for boiler masonry are mostly realized by the coop...

AI Technical Summary

Problems solved by technology

[0004] In order to enhance the connection strength between bricks, existing refractory bricks for boiler masonry are mostly realized by the cooperation between clamping blocks and clamping grooves. During the transportation process, there will be bumps between the bricks caused by the bumps of the transport vehicles, resulting in cracks at the connection between the blocks and the bricks. In severe cases, the blocks will break off from the bricks. Brick masonry has a certain impact, resulting in a reduction in masonry efficiency
