Description

Technical Field

[0001] The invention relates to the technical field of building component cleaning equipment, and specifically to a device for effectively treating wastewater and separating sand and gravel during the flushing process of PC (precast concrete) components, aiming to improve the utilization rate of water resources and reduce environmental pollution. Background Art

[0002] In the modern construction industry, PC component (Precast Concrete) technology is leading a revolution in construction methods. PC components effectively improve construction efficiency and building quality by pre-manufacturing concrete components in the factory and then transporting them to the construction site for assembly. However, in the production process of PC components, the flushing of rough surfaces is an important link and one of the main links in energy consumption and water resource consumption. This not only leads to a large amount of water resource waste, but also causes environmental pollution if impurities such as concrete particles in the flushing water are directly discharged without effective treatment. Although there have been some attempts to initially filter impurities in the flushing water by adding a filter, the above-mentioned filter is often simple in design, with limited filtering effect, and is easy to clog and requires frequent cleaning, which affects production efficiency and cost control.

[0003] The patent with application number CN202021149702.3 discloses a prefabricated wall panel rough surface flushing system with an automatic adjustment device, including a water flow trough, a hollow flushing platform is provided on the water flow trough, and flushing equipment, automatic sensing length adjustment equipment and adjustment system control panel are installed on the flushing platform. A primary sedimentation tank, a secondary sedimentation tank and a tertiary sedimentation tank which are connected in sequence are also provided on the side of the water flow trough. Grate baffles are provided inside the primary sedimentation tank, the secondary sedimentation tank and the tertiary sedimentation tank. The primary sedimentation tank is connected to the water flow trough, and a high-pressure water pump is installed in the tertiary sedimentation tank. The water outlet of the high-pressure water pump supplies water to the flushing equipment.

[0004] However, the above patent technology does not involve the wastewater treatment solution after the PC components are washed, nor does it mention how to separate the water and sand in the wastewater. Therefore, it is particularly important to design a device that can effectively separate the sand in the wastewater and recycle it. Summary of the invention

[0005] The object of the present invention is to provide a PC component flushing water sand and gravel separation device to solve the problems raised in the above background technology:

[0059] The flushing assembly is arranged at the bottom of the flushing platform 100, and the flushing assembly includes multiple flushing pipes 120, each of which is provided with multiple nozzles 121. The end of the water supply pipeline 930 is connected to the flushing pipe 120 of the flushing assembly, and the multiple flushing pipes 120 of the flushing assembly are arranged in the flushing platform.

[0060] The clean water tank 610 is respectively provided with an inlet 611 and an outlet 612. The inlet 611 of the clean water tank 610 is connected with the end of the drain ditch 200 through a pipeline. The level of the inlet 611 of the clean water tank 610 is lower than the level of the end of the drain ditch 200. The level of the inlet 611 of the clean water tank 610 is higher than the level of the outlet 612. The outlet 612 of the clean water tank 610 is connected with the starting end of the water inlet pipeline 920. Two partitions 613 are provided in the clean water tank 610. The partitions 613 are used to separate the clean water tank 610 into three purification chambers in sequence along the direction from the inlet 611 to the outlet 612. The level of the upper end surfaces of all the partitions 613 decreases in height in the direction from the inlet 611 to the outlet 612.
