Problems solved by technology

[0002] Clean coal, gangue and peat slurry are obtained from coal after coal washing process. Clean coal is used for steelmaking, while peat slurry is directly discharged to waste. A large amount of waste peat slurry has caused environmental pollution
[0003] The existing raw materials for making shale bricks are mainly mixed and crushed with shale, coal and gangue, and then mixed with water to make bricks. The cost of bricks made in this way is too high

Embodiment Construction

[0012] The present invention utilizes the peat obtained after sedimentation of coal waste peat slurry in the coal washing process (the peat slurry after coal washing is not convenient for transportation, and the peat slurry obtained after precipitation is convenient for transportation, and directly obtained after coal washing The ratio of peat slurry water to peat does not meet the process requirements,) as the raw material of peat bricks to make peat bricks, the specific production process is as follows:

[0013] 1) Crushing shale, the main material for making bricks, through a stone crusher to obtain shale powder.

[0014] 2) Mix peat and water in proportion (the weight ratio of peat and water is 3:7-6:4), and stir well to obtain peat slurry. In order to fully stir, peat and water can be mixed in proportion and put into a peat machine for stirring.

[0015] 3) Mix and stir the shale powder and peat slurry obtained in the preceding steps in proportion, and stir thoroughly to...

Abstract

The invention discloses a peat brick manufacture method, which comprises the following processing steps of: (1) shale is crashed into shale powder by a rock breaker; (2) peat and water are blended and stirred into a peat slurry; (3) the shale power obtained in the step (1) and the peat slurry obtained in the step (2) are blended and stirred to peat brick raw material; (4) the peat brick raw material is poured into a mould to be molded, dried, and baked to obtain the peat brick. The peat brick manufacture method has the advantages that the raw material is more uniformly stirred; the quality of the finished goods of the brick is increased; the finished brick has the clear outline, can reach the hardness standard of number 200 brick; the method makes waste profitable, reduces the cost and the pollution.

Description

technical field [0001] The invention relates to a method for making bricks, in particular to a method for making peat bricks. Background technique [0002] Clean coal, gangue and peat slurry are obtained from coal after the coal washing process. Clean coal is used for steelmaking, while peat slurry is directly discharged to waste. A large amount of waste peat slurry has caused environmental pollution. [0003] The existing raw materials for making shale bricks are mainly mixed and crushed with shale, coal and gangue, and then mixed with water to make bricks. The cost of bricks made in this way is too high. Contents of the invention [0004] The present invention utilizes discarded peat to provide a method for making peat bricks, the process steps of which are: [0005] 1) Shale is crushed into shale powder with a stone crusher; [0006] 2) peat and water are mixed and stirred into peat slurry; [0007] 3) mixing the shale powder obtained in step 1) with the peat slurry ...
