Vortex filter

Abstract

The invention relates to the technical field of filters for water quality purification treatment, and particularly relates to a vortex filter. The vortex filter comprises a filter body. The vortex filter is characterized in that a supporting layer, a lower quartz sand layer and an upper quartz sand layer are arranged at the bottom in the filter body sequentially from bottom to top; the upper part of the upper quartz sand layer is provided with a stirring tooth rake which is installed on a central drive shaft; the upper end of the central drive shaft extends out of the top of the filter body and is connected with an output shaft of a speed reducer; the lower part of the supporting layer is provided with a filtering plate which is provided with a filtering head; the bottom of the filter body is also provided with a back flushing water intake pipe and a first manhole; the side wall of the filter body is provided with a back flushing water drainage pipe, a water intake pipe, a pre-flushing pipe and a second manhole; the upper part of the filter body is provided with a gas exhaust pipe and a third manhole. According to the filter, the back flushing wastewater generation quantity and the back flushing time are shorted by 30%; the service life of a filter material is prolonged; the vortex filter is good in stability.

Description

technical field [0001] The invention relates to the technical field of filters for water purification treatment, in particular to a vortex filter. Background technique [0002] The filtering technology in the prior art has five series and multiple branches. Such as: filter series include single (double) valve filter, siphon filter, gravity three-valve filter; pressure filter series include pressure filter, variable aperture filter, circulating cleaning high-speed filter, floating filter material filter Devices, tubular precision filters, fiber filters, hollow fiber filters, etc. This technology designs all kinds of filters according to the degree of filtration or precision, and its filtration effect can meet people's needs, including water purifiers that are commonly used at present. However, there is a problem in all kinds of filters, which is to filter and intercept the dirt in the water. After reaching the storage capacity, the filtration duration will increase, and the...

Problems solved by technology

However, there is a problem in all kinds of filters, that is, to filter and intercept the dirt in the water. After reaching the capacity of the pollutants, the duration of filtration will increase, and the water quality will be difficult to maintain stably.

Some filters in the prior art use recoil structure to clean impurities, but if the initial impurities are closely combined with the filter material, it is difficult to achieve the backwash effect, and the excessive recoil flow and flow rate will seriously affect the stability of the filter material
