Abstract

A split-flow liquid filter. When the liquid to be treated with impurities quickly enters the bubbling chamber, the liquid to be treated with impurities precipitates fine impurities and produces splashes and a large number of bubbles enter the precipitation chamber; the liquid to be split with a lot of bubbles is first quickly filled In the sedimentation chamber, the discharge hole begins to overflow and discharge the liquid from the discharge hole. According to the specific gravity of the liquid, the discharged liquid contains floating impurities and a large number of bubbles floating on the water surface with a lighter specific gravity. A large number of bubbles can be diverted from the liquid. The liquid absorbs fine particles, resulting in floating impurities and fine particles with a lighter specific gravity, which will be discharged from the drain hole with the discharged liquid; while the liquid containing coarse particles flows into the inner cylinder chamber when it leads to the inner cylinder mouth , The coarse particles with heavier specific gravity are naturally deposited to the bottom of the precipitation chamber, so that the liquid sent from the liquid outlet pipe is a filtered liquid that does not contain floating impurities, a large number of fine particles and/or coarse particles.

Split-flow liquid filter

The present invention relates to a split-flow liquid filter capable of containing no floating impurities, a large amount of fine impurities and/or coarse-grained impurities with a heavier specific gravity.

Press, the common liquid filters on the market are sedimentation filters or mesh (filter type or filter paper type) filters; sedimentation filters are the difference in the specific gravity of the through substances, and the heavier substances settle to the bottom, usually only To filter out coarse particles with heavier specific gravity, in many occasions, it is not applicable because of the floating impurities or fine impurities in the liquid.

In addition, a general mesh filter uses a filter screen or filter paper to filter a large amount of impurities. Because a large amount of impurities will quickly accumulate on the filter mesh and cause blockage, the filter screen or filter paper has a short service life and must be maintained or replaced frequently. Filter or filter paper, often due to the high frequency of mesh cleaning or filter/filter material replacement, which causes a lot of work load or excessive consumption of the filter or filter material cost; in addition, there is a combination of sedimentation filter and mesh filter. The system or device, although the sediment filter is used for the pre-filtering operation, it can reduce the burden of filtering the impurities of the post-mesh filter. However, a large amount of dander and fines floating impurities will still cause a considerable degree of blockage of the filter mesh , Often when the filtered liquid is too dirty, it cannot meet the user's maintenance time requirements, especially the filter is difficult to filter out the fine impurities in the liquid, which makes the quality of the filtered liquid still need to be improved.

Therefore, in view of the problems existing in the above-mentioned conventional filters, filtration systems or devices The question is how to develop a filter for fluid filtration, which can significantly reduce the workload of the filter or filter material, and can increase the filter quality. This is really what consumers are looking forward to, and it is also the goal of the relevant industry to develop breakthroughs. direction.
