Description

Water purification device with adjustable water quality

Technical Field

The utility model relates to the technical field of water purification, in particular to a water purification device with adjustable water quality.

Background

The TDS (total amount of solids in water) values in municipal tap water in each region are quite different, and if water purifying equipment formed by the same filter material is simply installed, the filter material is easy to fail in a short time in regions with high TDS; in addition, even if the same area changes with the environment, the tap water quality can also change in a stepwise or periodic way, so that the water quality consistency cannot be achieved by independently designing the filter element aiming at the area.

Further, regardless of the regional differences, if the ultra-purification and filtration mode is adopted for one taste, the water quality is softer, and long-term drinking is harmful to health.

In summary, there is a need for an improvement in the existing water purifying apparatus to enable the water purifying apparatus to adaptively obtain filtered water with uniform quality according to different raw water conditions.

Detailed Description

The utility model will be further described with reference to the drawings and specific examples to aid in understanding the context of the utility model. The method used in the utility model is a conventional method unless specified otherwise; the raw materials and devices used, unless otherwise specified, are all conventional commercial products.

The utility model provides a water purifying device with adjustable water quality, which is shown in figure 1 and mainly comprises a first filter 1, a second filter 3, a sterilizer, a parallel branch and a water mixing tank 9 which are sequentially connected along a waterway.

Wherein, the raw water is pumped by the water pump and then is led into the first filter 1 through the pipeline, and in this embodiment, the filter element of the first filter 1 preferably comprises one or more of PP cotton, sintered activated carbon or granular activated carbon. Further, as shown in the figure, an ultrafiltration filter 2 is further connected in series to the water outlet end of the pre-filter 1, and the filtration particle size of the ultrafiltration filter 2 in this embodiment is selected to be 1-5 μm.

After passing through the ultrafiltration filter 2, the water enters a second filter 3, preferably the second filter 3 is specifically a ceramic filter, and adopts a two-stage tandem filter cartridge structure, and the filter cartridge of each stage is filled with microporous ceramic balls 4. Specifically, the microporous ceramic balls 4 selected in this embodiment are sintered from two or more materials of tourmaline (tourmaline raw stone) and clay. The water from the outlet of the second filter 3 flows into the sterilizer again, and specifically, the submerged ultraviolet sterilizer 5 is adopted for sterilization.

After water flows out from the outlet of the ultraviolet sterilizer 5, the water enters the parallel branch circuits which are arranged subsequently. In this embodiment, a total of two branches are designed, the upper branch is selected to be sequentially connected with a high-pressure water pump 6 and a reverse osmosis filter 7 in series, and each branch is provided with a flow control valve 8 which is electrically connected with a control system.

The two water pipes finally merge together into the mixing tank 9. A TDS detector is also arranged in the water mixing tank 9, and if the TDS of the water in the water mixing tank 9 is high, one path of flow of the reverse osmosis filter device 7 is regulated, and the other path of flow is regulated; similarly, if the water TDS in the mixing tank 9 is low, the reverse operation is sufficient. Therefore, the TDS value of the finally obtained purified water is consistent, and large fluctuation can not be generated due to different raw water quality in different areas.

When in use, the water can be taken out from the water mixing tank 9 through the water pump 10 and then flows out through the water outlet 11 for use/drinking.

In the description of the present utility model, it should be understood that the terms "left", "right", "upper", "lower", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must be provided with specific orientations, be configured and operated in specific orientations, and thus are not to be construed as limiting the present utility model.
