Preparation process of large balancing weight for gravity energy storage made of engineering residue soil

Abstract

The invention discloses a preparation process of a large balancing weight for gravity energy storage made of engineering residue soil. The preparation process comprises the following steps: (1) a screening procedure: screening the engineering residue soil to obtain a product a1 and a product a2; (2) crushing: crushing the product a1 to obtain a product b; (3) circulation process: mixing the product b into engineering residue soil, and repeating the steps; (4) drying: drying the product a2 to obtain a product c; (5) mixing and stirring: uniformly mixing and stirring the product c and a raw material h to obtain a product d; (6) burdening: mixing the product d with a hydrated adhesive and a fiber material, and uniformly stirring to obtain a product e; (7) a material injection procedure: injecting the product e into a material injection bin; (8) forming: pressing the product e in the injection bin into a forming bin to obtain a semi-finished balancing weight f; and (9) a maintenance procedure: the semi-finished balancing weight f is moved to a maintenance area, and a finished balancing weight g is obtained. The engineering residue soil is used for manufacturing the balancing weight, and the effective utilization rate of resources is increased.

Description

technical field [0001] The invention relates to the field of production technology for counterweight blocks, in particular to a process for preparing large counterweight blocks for gravity energy storage made from engineering slag. Background technique [0002] The counterweights used in gravity energy storage are generally huge in size. Traditional large-scale counterweights are mainly made of concrete as raw materials and are produced by the method of pouring; each production requires disassembly and assembly of the mold box, the process is complicated, and the cost of concrete is high. However, the existing automated production process is only for small counterweight blocks, and it is difficult to produce large counterweight blocks; at the same time, with the deepening of urbanization, the construction of projects blooming everywhere produces a large amount of engineering slag, the composition of which is complex and may contain gravel , broken bricks, cement blocks, etc....

Problems solved by technology

[0002] The counterweights used in gravity energy storage are generally huge in size. Traditional large counterweights are mainly made of concrete as raw materials and produced by pouring methods; each production requires disassembly and assembly of the mold box, the process is complicated, and the cost of concrete is high

However, the existing automated production process is only for small-scale counterweights, and it is difficult to produce large-scale counterweights; at the same time, with the continuous deepening of the urbanization process, engineering construction blooming everywhere produces a large amount of engineering slag, which has complex components and may contain gravel , broken bricks, cement blocks, etc., difficult to recycle

[0003] In addition, traditional counterweight production equipment uses mold injection and top pressure molding. When producing large counterweights, the middle and lower parts around the mold will be deformed due to extrusion, which will easily cause mold leakage and product deformation. The lower part of the product Not tight enough, the finished product is not strong enough and easy to crack, etc.
