Technical Field

Background

The method for making bricks by sludge mainly comprises two methods: one is to directly make bricks by using dried sludge; the other is brick making by using sludge incineration ash. When the dried sludge is directly used for making bricks, the components of the sludge are properly adjusted to be equivalent to the chemical components of brick making clay. When the sludge and the clay are mixed according to the mass ratio of 1:10, the sludge brick can reach the strength of the common red brick. The method for manufacturing the sludge brick is limited by the content of organic volatile components in a blank (sintering cracking is caused when a certain limit is reached, and the quality of the brick is influenced), and the sludge admixture ratio is very low, so that the method is difficult to be a suitable method for manufacturing the sludge building material from the viewpoint of the application limit requirement of the clay brick. When the sludge incineration ash is used for making bricks, the chemical components of the ash are relatively close to those of brick making clay, clay and the like. Thus, the manufacture of the sintered brick can be achieved in two ways: one is brick firing mixed with admixture; and secondly, independently firing the brick without adding an admixture.

When the brick materials are premixed, steam is added into the brick materials to cure the brick materials, so that the basic humidity of a brick blank is improved, the addition of water during later-stage brick material mixing is reduced, the water content of the brick blank is further reduced, the cured brick materials can effectively reduce the abrasion of a brick machine, and the service life of a wear-resistant part is prolonged; when the brick material was premixed, mixture such as clay was sneaked into to mud, wherein the compounding in-process, can contain the raw materials of great unqualified particle diameter in the raw materials, and this part impurity sneakes into to the brick material in, can influence the brick material quality.
