Description

Large-flow filter

Technical Field

The utility model relates to a filter especially relates to a large-traffic filter.

Background

The oily sewage passes through the walnut shell filter, suspended matters and oil droplets in the sewage are intercepted on the surface of a filter material layer or adsorbed on the surface of the filter material, after the operation is carried out for a period of time, when the saturated effluent quality of the filter material is deteriorated, water inlet is stopped and backwashing is carried out, so that the original characteristics of the filter material are recovered, the intercepted matters are taken away by backwashing water, and finally the effect of filtering oil and mechanical impurities is realized.

The backwashing mode of the walnut shell filter is mechanical stirring and water adding and washing. As shown in fig. 4, reference numeral 41 is a backwash agitation driving mechanism, reference numeral 43 is a backwash agitation blade, and reference numeral 42 is a water inflow distribution/backwash filter material intercepting device.
