Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a pure water production pretreatment system. Background Art

[0002] The pure water treatment system includes pure water equipment. During use, tap water can be adjusted to flow out after being processed by the pure water equipment. The pure water equipment can process tap water into pure water.

[0003] A multi-stage pure water treatment system usually first has to go through a pretreatment stage. The pretreatment stage mainly has two stages. The first stage is to remove suspended matter and solid particles in tap water, and the second stage is to adsorb organic matter, chlorine and certain heavy metals in the water. In the existing pure water treatment equipment, the pretreatment equipment is fixed during treatment and is a sequential flow-through filtration. Due to the single flow and the difficulties in cleaning, the filtration effect cannot reach the best under long-term trial. Therefore, this design designs a multi-stage pure water treatment structure in the pretreatment, so that it is easy to complete the pretreatment stage while also being convenient for timely maintenance and cleaning.

DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] This part mainly consists of three parts: tap water inlet structure, tap water pretreatment structure and tap water outflow structure after pretreatment.

[0016] The tap water inlet structure is realized by designing an upper seat 1, on which an inlet pipe 2 is arranged, and the water flows from the inlet 3 to the outlet 4 in sequence through the inlet pipe 2 penetrating the interior of the upper seat 1.

[0017] For the tap water pretreatment structure, firstly, the outlet 4 on the upper seat 1 is connected by the first connecting pipe 5. The first connecting pipe 5 is in a branch shape and is externally connected to a branch pipe 6. A first valve switch 7 is provided at the node between the first connecting pipe 5 and the branch pipe 6. The flow direction of the tap water is controlled by the first valve switch 7. Then, the end of the branch pipe 6 is connected to a water treatment tank 8. The invention point of this design is that the branch pipe 6 and the water treatment tank 8 are correspondingly arranged in multiple groups, that is, each water treatment tank 8 is independent, thereby greatly reducing the difficulty of handling the large-volume water treatment tank 8. When maintenance is required, a single water treatment tank 8 can be repaired in a targeted manner, thereby reducing the cost expenditure of the workers. For the filtering method of water treatment, an inner core layer 11 is provided in the water treatment tank 8. and an outer core layer 12, a filter layer is provided between the inner core layer 11 and the outer core layer 12, the filter layer is set in a cylindrical shape, and the filter layer is provided with holes for the initial filtration of tap water, thereby, large impurities flow into the inner core layer 11, and the direct water after the initial filtration enters the outer core layer 12 through the holes and flows along the connected filter tube until it flows into the second connecting tube 9, and a second valve switch 10 is loaded at the node between the filter tube and the second connecting tube 9. By controlling the second valve switch 10, the initially filtered tap water can flow into the box 15 at the port of the second connecting tube 9, and the activated carbon particles 16 filled in the box 15 are used to adsorb organic matter, chlorine and certain heavy metals in the water, thereby completing the tap water pretreatment stage.

[0018] Since impurities in the multiple water treatment tanks 8 in the present design will remain in the inner core layer 11 during filtration, in order to ensure a long working life and ensure its filtration quality, the present design also provides a mounting port 13 at the bottom of the water treatment tank 8, and a thread is provided on the inner side of the mounting port 13, and the mounting port 13 connects the inside of the inner core layer 11 with the outside, and a cover 14 is threadedly connected to the mounting port 13, that is, when repairing and cleaning the inner core layer 11 inside the water treatment tank 8, the cover 14 at the lower end can be opened to facilitate the staff to work inside it.
