Abstract

A filter pond blow-down pipe quick sand discharge device comprises a water inlet connection pipe, a flow guide pipe and a water outlet connection pipe which are connected with a blow-down pipe. A movable pipe connector and a filter screen assembly blocking filter materials are installed between the water inlet connection pipe and the flow guide pipe, and a valve and a matched flange fastener are disposed between the flow guide pipe and the water outlet connection pipe. The filter screen assembly is a double-layer stainless steel filter screen and internally provided with a double-layer 60-mesh stainless steel filter screen, and the material of the filter screen is adjusted according to treated water quality. The device is suitable for technical improvement of raw water and reclaimed water treatment of all existing power plants adopting common filter ponds, system operation does not need to be stopped during overhaul, and operation is convenient.

Description

technical field [0001] The invention relates to a filter material system, in particular to a rapid sand discharge device and method for an emptying pipe of a filter tank. Background technique [0002] Quartz sand filter material is the most common filter material. It has a wide range of uses and can be used for domestic drinking water and industrial production water, as well as filters of various pool types, sewage filters, and water purification mechanical filters. Quartz sand filter material has obvious characteristics: fast filtration speed, good interception effect, stable effluent quality, not easy to block and agglomerate. [0003] During the normal operation of the filter system, the filter material is the core of the process, and regular replenishment of the filter material to the filter becomes the main part of the operating cost consumption. How to avoid the loss of filter material has become a key consideration for designers and operators. The reasons for the lo...
