The invention patent with application number 201410671332.2 provides a kind of waste sintered brick and its preparation method, and the invention patent with application number 201710121394.X provides a kind of sintered brick and its preparation method, both of which use waste materials to manufacture sintered bricks, but now In some of these processes of using industrial waste to manufacture sintered bricks, the pressing molding process adopts the traditional method. The raw materials are poured into the cavity of the mold, and then the raw materials are pressed into a brick body by high pressure. Each cavity can only form one piece. Bricks, and need to demould after forming, resulting in low production efficiency

Abstract

The invention discloses a method for producing sintered bricks by using industrial wastes as a raw material. The method comprises the following steps of: collecting industrial wastes; pulverizing various industrial wastes respectively, and stirring the industrial wastes in a stirrer; mixing the industrial waste particles with water, and carrying out aging for 4-5h; weighing clay and cement, and uniformly stirring the clay, the cement and the aged industrial waste particles with water to obtain a mixed material; transferring the mixed material into a mold, and repeatedly rolling the mixed material to obtain a plate-shaped brick; placing the plate-shaped brick in a ventilated room for 3-5h, and then cutting the plate-shaped brick into bricks meeting a standard; and naturally air-drying the bricks, putting the bricks into a sintering furnace for sintering, and cooling the bricks after sintering to obtain finished products. The method provided by the invention is beneficial to treatment ofindustrial wastes, avoids environmental pollution, can bring economic benefits and also improves the production efficiency of sintered bricks.

Description

technical field [0001] The invention relates to the technical field of sintered brick production, in particular to a method for producing sintered bricks by using industrial wastes as raw materials. Background technique [0002] Sintered brick has a history of more than 2,000 years in my country, and it is still a widely used wall material today. There are many types of bricks, which are divided into clay bricks, shale bricks, coal gangue bricks, fly ash bricks, lime-sand bricks and slag bricks according to the raw materials used. [0003] Industrial waste, that is, industrial solid waste, refers to various waste residues, dust and other wastes discharged by industrial and mining enterprises in the process of production activities. It mainly includes the following categories: 1. Metallurgical waste, refers to all the residues and wastes discharged during or after smelting of various metals. Such as blast furnace slag, steel slag, various non-ferrous metal slag, ferroalloy ...
