Description

Water treatment device for enhanced membrane cleaning

【Technical field】

The invention relates to a water treatment device, in particular to a water treatment device which uses a high-pressure water column to drive a rotating plate to effectively scrape off impurities in the filter membrane and can improve the cleaning effect of the filter membrane.

【Background technique】

China Patent No. 200310116558.8 discloses a traditional water filter device, which is composed of a top cover, a bottom cover, a plurality of filter units and a plurality of stacked unit structures, and the filter units and stacked units It is stacked in pairs between the top cover and the bottom cover, wherein the filter unit has an annular filter membrane that provides the function of filtering out impurities, and the top cover has two side openings for water to enter. The unit is composed of a bearing ring seat, a stirring layer and an outer ring. The stirring layer is embedded in the middle of the bearing ring seat and the outer ring. The ring is provided with a number of ribs in the shape of a spiral curve. When high pressure When the water flows into the stacked unit from the side opening of the top cover, the agitation layer can use the force of the water flow to drive the ribs to rotate, so that the agitation layer can scrape off the impurities on the filter membrane in a rotating and oscillating manner, so as to achieve rapid decontamination Effect.

Although the above-mentioned water filter device does have the function of decontaminating the filter membrane, it still has its shortcomings in use and needs to be improved. The water filter device is equipped with multiple sets of filter units and stacked units from top to bottom. The agitation layer of the unit is driven by the momentum of the water flow, but after the water flow rushes down from the top cover, usually only the stacked unit on the upper layer can obtain enough water pressure to drive the agitation layer, the more the water flow passes through the more objects When the water pressure becomes insufficient, when the water flow reaches the stacked unit at the lower position, the momentum of the water flow is usually no longer able to drive the agitation layer, resulting in the lower stacked unit not being able to operate effectively to remove impurities and improving the decontamination effect. It is not ideal, and the agitation layer is embedded in the middle of the bearing ring seat and the outer ring. Since the inner and outer ring surfaces are subject to contact friction, the rotation of the agitation layer will generate greater frictional resistance, so the rotation of the agitation layer The smoothness is poor, and relatively high water pressure is required to achieve smooth rotation, which is not conducive to cleaning operations. In addition, the water filter device only uses the top and bottom covers to clamp and lock all filter units and stacked units. There is nothing outside that can be covered. When the water flow is filtered under high pressure, the water flow may overflow and splash, causing the surrounding environment to be humid, and the dust and debris flying in the air may also easily pollute the water source.
