Description

Abandon a class well of initial stage rainwater purifies

Technical Field

The utility model relates to a rainwater purifies technical field, specifically is a abandon class well of purifying initial stage rainwater.

Background

The complete rainwater discarding is called as initial rainwater discarding and is mainly applied to a rainwater collection and utilization system. During early rainfall, the rainwater of the front 2-5 mm generally pollutes seriously, and the flow rate is smaller. When the rainwater flows through the initial stage flow discarding filter device, the rainwater is discharged through the sewage discharge pipe with the lower opening due to the action of gravity. After the rainfall increases, the pressure on the baffle increases, the floating ball positioned at the upper end of the drain pipe closes the drain pipe under the action of the pressure of the water flow, the liquid level in the barrel rises, and the rainwater flows to the water outlet after being filtered through the horizontal filter screen and is collected. After the rain stops, the floating ball automatically resets under the action of the elastic force of the spring along with the reduction of the rainwater stored in the device, and the garbage generated by filtering in the barrel is taken out, so that the functions of discarding, filtering, automatically discharging and the like of initial rainwater are realized.
