Description

Rotary disc filter tank

Technical Field

The utility model relates to a filtration equipment technical field, in particular to carousel filtering pond.

Background

The central device of the rotary disc filter tank is a middle filtering rotary disc which is composed of 6 sectors, filter cloth is wrapped on the filtering rotary disc, the rotary disc filter tank belongs to a plug-in structure, the transport and the maintenance are particularly convenient, a driving motor at the upper right drives the rotary disc to rotate, a hollow central water collecting cylinder is arranged in the middle of the filter disc, a back washing device comprises a back suction sucker and a back suction pump, a sludge discharging device comprises a sludge pump and a bucket type sludge collecting groove, a porous sludge discharging pipe is arranged on the bucket type sludge collecting groove, and the sludge discharging device further comprises an automatic control system.

The operation state of the fiber rotary disc filter tank comprises the following steps: the filter is in a state of back washing and sludge discharge, during filtering, the sewage enters and exits from the outside, the sewage flows into the filter by gravity, a filter disc is completely immersed in the sewage, a water distribution weir is arranged in the filter, the water distribution in the filter is uniform, the inflow water generates low disturbance, the sewage is filtered by filter cloth, filter liquor is collected by a hollow tube and then is discharged out of the filter through an outflow weir, during cleaning, the filtering is still carried out, therefore, the filtering is continuous in the whole operation process, during cleaning, part of the sludge in the filtering is adsorbed in fiber wool filter cloth, a sludge layer is gradually formed, along with the accumulation of the sludge on the filter cloth, the filter cloth filtering resistance is increased, the water level of the filter is gradually increased, a pressure sensor in the filter monitors the liquid level change in the filter, and when the liquid level in the filter reaches a cleaning set value (high water level), a PLC can start a back washing pump to start the cleaning process.

But the prior rotary disc filter chamber has the defects that: 1. carry out the conduction through gear and chain between driving motor and the center tube and connect, the gear and the chain in the outside all directly expose in sewage, rust easily after using for a long time, influence conduction efficiency, 2, mud, impurity etc. fall to the interior bottom of carousel filtering pond, are difficult for being taken out. Therefore, we propose a rotary disc filter.
