Circular self-desilting type gravity desilting filter tank

Abstract

The invention discloses a circular self-desilting type gravity desilting filter tank, and relates to a desilting tank. The desilting filter tank comprises an outer-layer desilting basin body, whereinthe outer-layer desilting basin body comprises a diversion canal section, a centrifugal desilting section, a flow adjusting section and a tail desilting section; the diversion canal section, the centrifugal desilting section, the flow adjusting section and the tail desilting section jointly form a closed inner-layer desilting basin body. A first overflow weir is arranged between the tail desiltingsection and the inner-layer desilting basin. A second overflow weir is arranged on the inner sides of the diversion canal section, the centrifugal desilting section and the flow regulating section, and the second overflow weir and the inner side wall of the outer-layer desilting basin jointly form a clear water area. A desilting gallery is arranged on a concave bank of the centrifugal desilting section, a third sand inlet hole is formed in the bottom of the inner-layer sedimentation tank, and a drainage pipe is arranged at the lower end of the clean water tank. According to the desilting filter tank, bed load particles and suspended load particles in water in a channel can be effectively removed, and automatic desilting can be achieved through the desilting filter tank.

Description

technical field [0001] The invention relates to a sand settling tank, in particular to a circular self-discharging gravity sand settling filter tank with the function of removing transported particles and suspended matter particles in the canal water. Background technique [0002] In water-scarce areas with uneven rainfall, the shortage of water resources seriously restricts the life and economic development of local people. In order to solve this problem, in addition to strengthening people's water-saving awareness and restricting groundwater exploitation, a more active and proactive approach It is the artificial recharging of groundwater resources. [0003] At present, in the lower reaches of the Yellow River, in order to actively cope with the shortage of water resources and make full use of rain and flood resources, people often recharge the collected rain and flood water and the cited Yellow River water through recharge facilities (recharge wells or recharge ponds) to ...
