Waste residue utilization system of concrete mixing plant and operation technology

Abstract

A waste residue utilization system of a concrete mixing plant comprises a waste slag pool, and a submersible agitator and a slag slurry pump a are arranged in the waste slag pool; the slag slurry pump a is connected with a classifying screen; one end of a stone outlet of the classifying screen is connected with a clean water pump, and a sand setting pool is arranged on one side of the classifying screen; a slag slurry pump b is arranged in the sand setting pool and is connected with a cyclone separator, and a sand leaking opening is formed in the lower end of the cyclone separator; a sand storage pool is arranged below the sand leaking opening, and a sewage outlet is formed in the top of a cyclone; a sewage pump is arranged in a sewage pool, and is connected with a sewage dosing scale through a connecting pipeline, and the sewage dosing scale is connected with a sewage draining pump; and the sewage draining pump is connected with the agitator. The waste residue utilization system has the beneficial effects that by means of the waste residue utilization system of the concrete mixing plant, waste zero discharge of the mixing plant can be completely achieved, energy saving and environmental protection are achieved, the cost is low, and the system is simple, easy to implement, short in construction period, and high in automation degree and is an energy-saving environment-friendly preferred product of related enterprises.

Description

technical field [0001] The invention relates to the field of waste recycling of concrete mixing plants, in particular to a system for utilizing waste residues of concrete mixing plants and an operating process thereof. Background technique [0002] Concrete is the most important material in civil engineering. With the increasing scale of construction, the reinforced concrete structure has become the main body of the building structure, which makes the production of ready-made concrete develop rapidly. Concrete mixing plants need to wash mixers and transport vehicles every day, and a large amount of waste concrete, waste slurry and waste water will be generated in the process. Concrete mixing plants have large production capacity and high benefits, but they also cause serious environmental pollution. A small and medium-sized mixing plant with an annual production capacity of 200,000 cubic meters produces 5,000 tons of sewage and 3,000 cubic meters of waste residue. Some mix...

AI Technical Summary

Problems solved by technology

Some mixing plants have no place for dumping sewage and waste residues, and many drivers dump these sewage and waste residues at will, which not only seriously pollutes the environment, but also wastes at least 200,000 yuan in raw material costs every year.
