Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a multi-stage filtering PP filter element filter. Background Art

[0002] PP cotton filter is a filter that uses polypropylene cotton (Polypropylene) as the filter material. Polypropylene cotton is a high-efficiency filter material with good chemical stability, high temperature resistance and corrosion resistance. It can effectively filter out impurities such as suspended matter, particles, silt, rust, etc. in the water and improve the purification effect of water quality.

[0003] For example, the Chinese utility model patent with announcement number CN211611752U discloses a PP cotton filter, including a housing and a PP cotton filter element. When in use, the filter element is formed by stacking PP cotton filter sheets. In this way, the corresponding number of PP cotton filter sheets can be selected according to the flow rate of the water inlet, which will not cause waste of filter elements and can be applied to water purifiers with different flow rates without the need to manufacture filter elements of various specifications.

[0004] The above solution has the following problems: during use, different numbers of PP cotton filters need to be adjusted according to different water qualities, which is cumbersome to operate, and since it does not have a multi-stage filtration structure, it is impossible to filter impurities in the water multiple times, thereby failing to ensure that the water quality after filtering is qualified.

[0005] Therefore, we proposed a multi-stage filtration PP filter element filter to solve the above problems. Utility Model Content

[0008] The above technical solution can be used to preliminarily filter the water entering from the water inlet through the PP cotton filter element, and the larger suspended particles and solid impurities, such as mud, rust particles, etc., can be removed through the outer filter layer.

[0009] As a preferred technical solution of the utility model, the middle filter layer is located directly below the outer filter layer; the middle filter layer is fixedly installed inside the shell; the middle filter layer uses a medium-sized PP filter element.

[0010] The above technical solution can further remove smaller suspended particles and solid impurities, such as fine particles, sediments, etc. through the middle filter layer.

[0011] As a preferred technical solution of the utility model, the inner filter layer is located directly below the middle filter layer; the inner filter layer is fixedly installed inside the shell; the inner filter layer uses a PP filter element with a smaller pore size.

[0012] The above technical solution can remove tiny suspended particles and solid impurities, such as bacteria, viruses, bacterial clusters, etc. through the inner filter layer.

[0013] As a preferred technical solution of the utility model, the activated carbon layer is arranged on the right side of the shell below the inner filter layer; the activated carbon layer is fixedly installed at the inner opening of the water outlet.

[0014] The above technical solution can remove odor, residual chlorine, organic matter, etc. in the water discharged through the water outlet through the activated carbon layer.

[0015] As a preferred technical solution of the utility model, the water outlet is opened at the lower right position of the shell; the water outlet is connected with the throttle valve at the outer part of the shell.

[0016] The above technical solution can be used to control the flow rate and flow rate of the water flow at the water outlet through the throttle valve.

[0018] By adopting the above technical solution, the liquid entering the shell from the water inlet can be stored in the water storage shell to facilitate the first filtration of the PP cotton filter element, and then discharged from the filter element port after the filtration is completed.

[0019] As an optimal technical solution of the utility model, a return pipe is opened on the left side of the shell; the top of the return pipe is connected to the water inlet, and the bottom of the return pipe is connected to the chamber below the inner filter layer; the return pipe is connected to the return water pump outside the shell.

[0020] The above technical solution can control the liquid that does not meet the filtering standards to flow back to the water inlet for further filtration through the reflux pump and the reflux pipe.

[0021] As a preferred technical solution of the utility model, a water quality detector is arranged in the chamber below the inner filter layer; the water quality detector is fixedly installed at the bottom of the inner cavity of the shell.

[0022] The above technical solution can be used to detect whether the liquid after filtration meets the standards through a water quality detector. Liquid that meets the standards is discharged through the water outlet, and liquid that does not meet the standards is returned to the water inlet through the reflux pipe for refiltration, thereby ensuring water quality.
