With the increase of population and the rapid development of industrialization and urbanization in my country, according to statistics, my country's construction waste produces 3.5×10 9 t, and this figure is still growing and will reach 7.0×10 in the next few years. 9 t. Therefore, the resource utilization of construction waste is the most important way to manage construction waste in the future. At present, the research status shows that in the process of recycling construction waste, there is still a lack of effective treatment methods for screening strip waste. Therefore, this patent, from the perspective of energy saving, solves the problem of the difficulty of screening strip waste in the current recycling of construction waste. Summary of the invention

[0003] In view of the problems existing in the recycling of construction waste, the present invention provides an energy-saving water selection device.

The side walls of the annular guide groove are provided with vertical plug-in blocks, and the two sides of the filter storage box are correspondingly provided with plug-in grooves, and the two are plug-in connected for easy disassembly and assembly. The plug-in blocks and plug-in grooves can be set in multiple groups accordingly, or plug-in devices can be added to the bottom surface of the filter storage box and the annular guide groove to improve the stability of the installation of the filter storage box.

[0008] Furthermore, the filter storage box is a rectangular hollow box, and its four side walls are arranged as a rectangular grille structure. The grille on the side facing the impact of the water flow is larger, and the grille on the side facing away from the impact of the water flow is smaller, which is convenient for collecting bagged objects; and a box fixing frame is arranged on the side facing away from the impact of the water flow.

The salvaged strip-shaped waste does not need to be broken up, which solves the problem of downtime caused by strip-shaped material blocking during the recycling of construction waste.

[0015] Its working principle is as follows: the raw materials and water of construction waste enter the water selection device through the feed hopper, and the construction waste is completely immersed in water during the operation of the screening and conveying device. Since the density of recyclable materials is greater than that of strip waste, the recyclable materials sink to the bottom and are transported to the outside of the water selection device by the screening and conveying device and the conveying and conveying device; the strip waste floats on the surface, and the booster pump is started to increase the flow rate of the water flow in the circular arc guide groove. The water flow drives the three-tooth arc claw to rotate, and the strip waste is salvaged into the upper arc guide groove, and discharged to the filter storage box with the rapid current in the circular arc guide groove. After the filter storage box is full, it can be easily replaced, thereby realizing the salvage of strip waste; after a period of use, the slag discharge port is opened to clean the entire device.

[0016] The present invention adopts a double-layer structure, the upper layer is a screening and storage layer for strip-shaped objects, and the lower layer is a cleaning and conveying layer for useful recycled materials. The water flow in the upper layer is in a torrent state, and the water flow in the lower layer is close to a horizontal flow. The function of the booster pump is to increase the power of the water flow and ensure that the upper water circulation has sufficient power. Under the impact of the torrent of the upper water flow, the three-tooth arc-shaped claw rotates continuously, and during the rotation, the strip-shaped waste on the bottom layer is brought to the upper layer and transported to the filter storage box with the water flow. The three-tooth arc-shaped claw does not need to be driven, and there is no need to crush the strip-shaped waste, so the device has a good energy-saving effect. BRIEF DESCRIPTION OF THE DRAWINGS
