Automatic back-flush, regeneration filter

Abstract

The invention provides an automatic backwashing and regeneration filter, comprising a filter tank which is internally provided with a filter layer; a clean water tank used for storing clean water after filtration is arranged above the filter layer; the clean water tank is provided with a clean water outlet; an oxygenation water distribution tank used for increasing the oxygen content in water is connected in series between the filter layer and the original water inlet; the filter layer comprises an active carbon filter material; and a siphon pipe which can carry out automatic backwashing on the filter layer is branched out of the pipeline between the filter layer and the oxygenation water distribution tank. Compared with the prior art, the filter has the advantages as follows: 1. as the oxygenation water distribution tank is arranged, the oxygen content in water is improved so as to lead the organic matters and bacteria attached to the active carbon to be sufficiently degraded under the condition of sufficient oxygen and leads the active carbon to have the function of automatic regeneration; and 2. by adding structures such as siphon generation pipe, siphon destroy pipe and the like, the equipment can carry out the backwashing operation on the filter material automatically without needing manpower maintenance, saves manpower, and has quick sewage disposal speed, high efficiency and wider applicable range.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a filter with automatic backwashing and automatic regeneration of filter material. Background technique [0002] Filtration is an important way to treat and reuse existing domestic and production wastewater. Therefore, various filtration methods and filtration equipment are also available. Conventional filters generally include a water pipe and a filter layer, wherein the filter layer is used to filter impurities and other polluting and harmful components in the water, which can be set according to the nature of the water to be filtered. However, there are some defects in this form of filter. For example, after a long time of filtration, a large amount of impurities will accumulate at the raw water end of the filter layer, which will cause the filter layer to block and fail to work. There are two existing solutions. The filter layer is disassembled and then cleaned. Another way is to ...

However, there are some defects in this form of filter. For example, after a long time of filtration, a large amount of impurities will accumulate at the raw water end of the filter layer, which will cause the filter layer to block and fail to work. There are two existing solutions. The filter layer is disassembled and then cleaned. Another way is to pass the reverse water flow in the filter water pipe to wash the accumulated impurities from the filter layer.

For the first method, because the filter layer needs to be disassembled and reinstalled, the whole process is complicated and cumbersome, which wastes manpower time. It is not suitable for some large-scale filter color equipment that needs uninterrupted work; for the second method, although The trouble of disassembly and assembly is saved, and a reverse flushing water pump is generally installed in the existing filter. Obviously, this method requires additional energy consumption, which is undoubtedly unacceptable in today's increasingly scarce energy sources.

[0003] However, even if the sundries on the filter layer can be removed by backwashing, there will still be a lot of bacteria and organic matter on the filter layer after long-term use, which is difficult to clean up by backwashing, and the filter layer can only be replaced.
