Sewage waste residue recycling system of concrete mixing station and equipment thereof

Abstract

The invention provides a sewage waste residue recycling system of a concrete mixing station and equipment thereof. Mixed starch separated by a sand and stone separator is filtered to obtain separatedclean water and waste residues. The separated clean water is used for production of the stirring station or washing a tank of a concrete transport cart. The waste residues are used for production of the stirring station or are returned to the mixed starch to be uniformly stirred again. On the one hand, the damage of waste water to a stirring pond, a conveying pipeline and a pressurizing pump is reduced and on the other hand, an effect of cyclic utilization of the waste residues is promoted. Meanwhile, the freshness of the waste residues is ensured by means of the system and the equipment, so that the waste residues can be directly put into production for application, and therefore, the consumed time and cost for disposal of filter residues and filter cakes are saved.

Description

technical field [0001] The invention relates to a concrete mixing plant, in particular to a recycling system and equipment for sewage and waste residue of a concrete mixing plant. Background technique [0002] With the development of the economy and the advancement of technology, higher requirements are put forward for the environmental protection, energy saving and usability of commercial mixing plants. In particular, the recycling of concrete waste in concrete production enterprises and the treatment of sewage have attracted more and more attention from enterprises and society. The waste concrete and the sewage generated in the concrete production process are very serious to the environment and must be recycled. [0003] There are generally two types of existing recovery modes, one is that the slurry water after sand and gravel separation is directly pumped to the concrete mixing equipment to participate in production; Allow to dry before disposal. The problem with the ...

AI Technical Summary

Problems solved by technology

The problem with the first mode is that the amount of slurry water is very large and cannot be used up, and the slurry water will become thicker and thicker, and it is easy to clog the mixing tank and the pipeline. Since the slurry water contains a certain amount of fine sand and pebbles, It cannot pass through the booster pump, and must enter the concrete mixer alone, so that the sewage cannot be sprayed evenly, and the mixing time needs to be prolonged; the problem with the second mode is that the filter cakes produced are all dried by wind and sun. , and then dispose of the dried filter residue filter cake, and generally need to pay a certain fee for the disposal
