A recycling system for waste concrete

Abstract

The invention discloses a recycling and processing system for waste concrete, which comprises a tank car unloading platform, a feeding hopper, a separator and a sewage treatment pool connected in sequence. A discharge opening is opened on one side of the tank car unloading platform, and the feeding The hopper is installed on the tank truck unloading platform above the discharge port. The feed hopper is composed of a plurality of single hoppers arranged in a fan shape. The bottom of each single hopper has a funnel opening connected with the discharge port. The separation There is a screening bucket between the machine and the feeding hopper, the inlet of the screening bucket is connected with the funnel mouth of all single buckets, and the outlet of the screening bucket is connected with the feeding port of the separator through a feeding pipe. By changing the structure and arrangement of the feeding hopper, the present invention can meet the needs of multiple tank cars for flushing and discharging sewage, and at the same time avoid as much as possible the occurrence of initial condensation due to the excessively long distance of sewage discharge and delivery, which will cause blockage between the feeding hopper and the separator body The phenomenon, from the separation of links to reduce the possibility of the entire system paralyzed.

Description

technical field [0001] The invention relates to the technical field of recycling waste concrete, in particular to a recycling and processing system for waste concrete. Background technique [0002] Concrete refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to the use of cement as cementitious material, sand and stone as aggregates and water in a certain proportion. Stir. In the process of concrete production or use, some excess waste will always be generated. Landfill disposal of these waste concrete will seriously pollute the environment. Therefore, it is necessary to separate these waste concrete through recycling equipment and then process and recycle them to realize waste utilization. [0003] At present, the sand and gravel separator has become a mature equipment for the separation of waste concrete. As the most important part of the entire recycling s...

But in actual operation, usually several tank trucks clean and discharge sewage at the same time, and all the blends of concrete and sewage are uniformly discharged into the feed pipe through a long feed hopper and then slide into the separator body. However, due to the feed If the length of the hopper is too long, it is difficult to discharge the mixture of concrete and sewage, and condensation often occurs, which further leads to blockage between the feed hopper and the separator body, which makes the most important part of the entire recovery system appear. Paralyzed or processing efficiency is too slow, resulting in the inability of the entire recycling system to effectively process waste concrete
