Sintered brick prepared from waste paper papermaking sludge and preparation method thereof

Abstract

The invention relates to the technical field of papermaking sludge recycling, in particular to sintered bricks prepared from waste paper papermaking sludge and a preparation method thereof. The sintered brick comprises a sintered brick body, a plurality of communicating holes are formed in the sintered brick body, two grooves are formed in the outer wall of one side of the sintered brick body, twoprotrusions are arranged on the outer wall of the side, away from the grooves, of the sintered brick body, and limiting grooves are formed in the two sides of the top of the sintered brick body. Thepreparation method of the sintered brick is simple; the waste paper papermaking sludge can be used for preparing sintered bricks; the sintered brick prepared by mixing the waste paper papermaking sludge is not easy to crack and good in use performance, resources are fully utilized, the environmental protection property is good, the waste paper papermaking sludge is stirred before the waste paper papermaking sludge is used, impurity waste in the waste paper papermaking sludge is taken out, a bactericide is added, mixing of the waste paper papermaking sludge and the sintered material is facilitated, bacterium breeding is reduced, the cement amount generated when the sintered brick bodies are piled into a wall through cement is reduced, and part of cost is saved.

Description

technical field [0001] The invention relates to the technical field of papermaking sludge reuse, in particular to a sintered brick made from waste paper papermaking sludge and a preparation method thereof. Background technique [0002] Sintered bricks use clay, shale, coal gangue or fly ash as raw materials, and the bricks used for masonry load-bearing and non-load-bearing walls made by molding and high-temperature roasting are collectively called sintered bricks. It has the characteristics of wide range, high strength, compression resistance, wear resistance and various colors. We can often see it in masonry projects and daily life. It has various specifications and sizes to meet the needs of different occasions, and is widely used in In various fields, a large amount of sludge produced by the current paper industry has brought serious pollution to the environment, and raw materials such as sludge and clay can be made into fired bricks and can be reused. [0003] The prepa...

Problems solved by technology

[0003] The preparation method of sintered bricks made from waste paper and papermaking sludge is complicated. After mixing waste paper and papermaking sludge, the sintered bricks are easy to crack and cannot fully utilize resources. There are impurities in the waste paper and papermaking sludge, such as If no treatment is carried out, the quality of sintered bricks will be affected. When sintered bricks are piled with cement, the amount of cement will be large, and the cost will increase. If the cinder is not properly screened, sometimes there will be cracks in the sintered bricks, and the body of the sintered bricks is not easy to take. The environment for brick firing needs to be improved, and the weight of fired bricks is heavy and it is inconvenient to stack and transport. Therefore, it is urgent to design fired bricks made from waste paper papermaking sludge and its preparation method to solve the above problems
