Sintered brick prepared by utilizing paper mill sludge and preparation method thereof
The invention discloses a sintered brick prepared by utilizing paper mill sludge and a preparation method thereof. The sintered brick is formed by the following components in part by weight: 7 parts of clay, 2 parts of coal gangue and 1 part of sludge. The preparation method comprises the following steps of (1) crushing and filtering the coal gangue, and feeding into a coal gangue feeder; (2) crushing and filtering the clay, and feeding into a clay feeder; (3) fully mixing the sludge, the processed coal gangue and the processed clay through a distributor according to a fixed proportion to prepare a raw material, and blank forming, drying and sintering the mixed raw material to prepare a finished product. The applicant finally discovered the mixed proportion of 7 to 2 to 1 through a number of research experiments and trial production and continuous compressive strength detection of bricks, so that the compressive strength of the bricks meets the national standard, the product quality is high, some products reach the level of products of the same kind in advanced countries, the market is broadened, and the application surface is gradually enlarged. Not only is the difficult problem of sludge treatment of a paper mill solved, but also the consumption of the clay and the coal gangue caused by traditional sintered bricks is avoided.
