Embodiment 1

[0026] See attached figure 1 , attached figure 2 And attached image 3 , a continuous hydraulic grading and sorting device for particulate matter in a water body of the present invention, comprising a hydraulic separator, the hydraulic separator is multi-stage, and the multi-stage hydraulic separators are connected in sequence, along the flow direction of the water body, the multi-stage The cross-sectional area of ​​the hydraulic separator increases successively, and the installation height of the multistage hydraulic separator decreases successively; the hydraulic separator includes a cylinder 13 for particle separation, and an overflow tank 14 is provided on the top of the cylinder 13, The bottom of the cylinder 13 is provided with a sedimentation bucket 16 for collecting particles, the cylinder 13 is connected with the water inlet pipe 10, the overflow tank 14 is connected with the outlet pipe 15, and the sedimentation bucket 16 is connected with the discharge pipe 17; th...

Embodiment 2

[0034] A continuous hydraulic grading and sorting method for particulate matter in a water body of the present invention is carried out on the continuous hydraulic grading and sorting device for particulate matter in a water body in Embodiment 1, comprising the following steps: 1) transporting the water body to be classified and sorted Go to the hydraulic separator with the smallest cross-sectional area, so that the water body to be classified and sorted passes through all the hydraulic separators in turn, and the concentration of particulate matter in the classified and separated water body is not greater than 500mg / L; 2) After the classification and sorting is completed, pass through The discharge pipe 17 collects the sediment and separates the classified particulate matter.

[0035] In the present invention, the granular matter in the water body is classified and separated in the above-mentioned hydraulic separator, which is a classification and separation method based on th...

Embodiment 3

[0037]This embodiment is a device and a sorting method for continuous hydraulic classification and separation of particulate matter in laboratory water. The continuous hydraulic classification and separation device for particulate matter in the water body is the water distribution tank 2 in turn, and the water distribution tank 2 is equipped with agitator The device 1 and the water distribution tank 2 are used to prepare water bodies that need to be graded and sorted.

Abstract

The invention provides a continuous hydraulic classification and separation device of particulate matters in a water body and a separation method thereof. The continuous hydraulic classification and separation device comprises hydraulic separators connected in sequence and with multistage cross section areas being enlarged in sequence; each hydraulic separator comprises a drum body; an overflowinggroove is arranged at the upper part of the drum body, a depositing hopper is arranged at the bottom part of the drum body, the drum body is connected with a water feeding pipe, the overflowing groove is connected with a water discharging pipe, and the depositing hopper is connected with a discharging pipe; a flow guiding drum is arranged in the drum body, a reflecting plate is arranged at the bottom part of the flow guiding drum, the water feeding pipe extends into the flow guiding drum, and a water outlet is also arranged at the bottom part of the flow guiding drum. The invention also provides a method for separating the particulate matters in the water body on the device. The continuous hydraulic classification and separation device of the particulate matters in the water body and theseparation method provided by the invention have the beneficial effects that the hydraulic separators with unique structural designs are adopted, the rising flow speed of the water body is lower thanthe sinking speed of the particulate matters, and the particulate matters are deposited in the deposition hopper; conversely, when the rising flow speed of the water body is higher than the sinking speed, the particulate matters enter the next-stage hydraulic separator; the structure is simple, the classification effect is good, the collection is convenient and the separation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of particle separation and classification in water bodies, in particular to a continuous hydraulic classification and separation device for particles in water bodies and a separation method thereof. Background technique [0002] Artificial groundwater recharge can effectively alleviate the problems caused by the shortage of groundwater resources, land subsidence and seawater intrusion. Artificial groundwater recharge refers to the use of recharge wells to irrigate water into the aquifer. The commonly used recharge methods include atmospheric pressure recharge and pressurized recharge. In order to ensure the normal use of the recharge well, pumping (water pumping) must be carried out at regular intervals to avoid clogging of the aqueous medium. The clogging of aqueous medium greatly limits the effectiveness of artificial recharge, and even directly leads to the scrapping of recharge facilities. However, the ...
