Embodiment 1

[0035] A sand-water separator, comprising a primary settling machine 1, an intermediate settling machine 2 and a final settling machine 3.

[0036] The primary precipitator 1 is used for the separation of coarse particle impurities; the intermediate precipitator 2 is used for the separation of medium particle impurities; the final precipitator 3 is used for the separation of fine particle impurities.

[0037] The primary sedimentation machine 1 includes a water inlet 15 , a primary sedimentation tank 21 and a sand lifting pipe 23 . The sand-lifting pipe 23 is an inner hollow cylinder, which is arranged obliquely. The lower part of the sand-lifting pipe 23 communicates with the water inlet 15 and the primary sedimentation tank 21. A rotating shaft 8 is installed inside the sand-lifting pipe 23, and several brackets 17 are spirally arranged on the rotating shaft 8. Rubber spiral blade 11 is fixed on the bracket 17, the diameter of the spiral blade 11 coincides with the inner dia...

Abstract

The invention relates to a water purification device which comprises a primary settling machine, an intermediate settling machine and a terminal settling machine. The sludge water is precipitated and dehydrated in multiple stages by the primary settling machine, the intermediate settling machine and the terminal settling machine. According to the particle size of sludge, the sludge is discharged at three levels and the clear water is recycled. The water purification device overcomes the problems of large occupied area of the settling basin, low efficiency, difficulty in clearing settled sludge and low utilization rate of water resources in the prior art, settles and discharges the sludge according to the particle size and ensures the reutilization of the sludge. Additionally, compared with the settling basin construction, the water purification device has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to water treatment equipment, which is mainly used for the treatment of solid suspended matter in sewage, especially a water purification equipment for treatment of pyrite tail water. Background technique [0002] At present, the tailing water treatment of pyrite ore dressing mostly uses the sedimentation tank to settle the sediment-containing water. After sedimentation, the cleaner water on the surface of the sedimentation tank is reused. The waste sand is dehydrated by exposure to the sun, and the sedimentation tank is manually cleaned. This method occupies a lot of land and has low efficiency. At the same time, the reuse of water resources is low, and the waste sand is mixed in thickness and fineness, which is not conducive to reuse. Contents of the invention [0003] The purpose of the present invention is to provide a kind of water purification equipment that realizes the separation of sand and water through the joint actio...
