Description

Filtering equipment

Technical Field

The invention relates to the field of water filtration, in particular to a filtering device.

Background

With the rapid development of social economy, people bring abundant substances and serious environmental pollution, wherein the water pollution is particularly prominent. The waste water, waste residue, waste gas and the like discharged by the factory not only directly pollute surface runoff, but also permeate underground to pollute underground water. In order to ensure the safety of drinking water, water in a tap water pipe is usually filtered by a water purifier, which has become a necessary water treatment device for households. In the water purification process of the water purifier, floaters, heavy metals, bacteria, viruses, residual chlorine, silt, rust, microorganisms and the like in water are removed by the filter element assembly, so that the water safety is ensured. However, the general water purifier only performs one-level filtration on tap water, cannot realize multi-level filtration, and is inconvenient for replacing a filter element. In areas with serious water pollution, when people need to wash clothes or general household appliances, if tap water is directly adopted for washing, the clothes can not be really washed clean because of silt, rust and the like in the tap water; if the filtered purified water is adopted for cleaning, the waste of the purified water resource is caused. When people need to wash vegetables or wash food directly entering the mouth, if tap water is used for washing, the standard of entering the mouth for eating can not be met; if the filtered purified water is adopted for cleaning, the waste of the purified water resources is also caused. Therefore, the single-stage filtering equipment cannot meet the requirements of life, and inconvenience is brought to life.
