Problems solved by technology

This system can process a large amount of waste concrete, so that the generated waste slurry can be recycled for the production of new concrete, which saves resources. However, in this method, a fixed volume adjustment tank is used to weigh the tank body. In this structure, due to the support column Installing a weighing device on the top will greatly reduce the support strength of the tank body, causing safety hazards. In addition, when the tank body is too large, it will cause difficulties in equipment installation

Abstract

The invention relates to a concrete sewage recovery treatment system and a method.The system comprises a gravel separation mechanism and a fine sand recovery mechanism, most of gravel in concrete sewage can be separated and recovered, sewage obtained through separation is discharged into a blending pool, and a sewage blending mechanism is arranged in the blending pool; a measuring block suspended in sewage is arranged in the sewage blending mechanism, the density of the sewage in the blending pool is calculated by utilizing the principle that the hollow measuring block is subjected to different buoyancy forces in water bodies with different densities, and the mass of clean water needing to be added is calculated through the water body concentration, so that the specific concentration of the sewage is blended; the large-batch preparation process of the concrete sewage is effectively realized, and the preparation efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of concrete recovery and utilization, and relates to a system and method for recovery and treatment of concrete sewage. Background technique [0002] Many sewage recovery and treatment systems currently on the market can only solve the problem of sand and gravel separation of sewage and the collection, sedimentation, and uncertainty of sewage concentration. As a result, laboratory technicians in concrete companies dare not reuse them for fear of affecting the quality of concrete; In the technology, the intermittent sewage deployment method is often used to keep the sewage concentration within the setting range of the concrete enterprise laboratory, so that the concrete sewage can be reused and zero discharge of sewage can be realized. However, this method requires multiple deployments of sewage, and the deployment efficiency is low. In addition, due to systematic errors in each deployment process, the cumula...
