Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a water distributor and water treatment equipment. Background Technology
[0002] Water treatment equipment is widely used in factories for water softening and in homes for water purification. Taking a water softener as an example, it primarily removes calcium and magnesium ions from water through ion exchange resin, thus reducing water hardness. The commonly used softening agent in water softening is resin. After producing soft water corresponding to the amount of resin added during ion exchange, the resin becomes saturated with hardness ions, requiring resin regeneration. This regeneration involves replacing the hardness ions within the resin with regenerated material, allowing the softening agent to continue to be used.
[0003] The water distributor is a crucial component of a water softener. "Water distribution" refers to the systematic arrangement of water across a defined working area, most commonly by evenly distributing water across the surface. For example... Figure 1 As shown, the existing water distributor is a conical cylinder with water outlets extending vertically around its circumference. However, during brine flushing, some brine flows out through the gap between the distributor and the central pipe, resulting in a concentrated water flow and uneven water distribution.

[0020] Another objective of this invention is to provide a water treatment device, such as a water softener or a filter tank.
[0021] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0022] A water treatment device includes a housing, a valve assembly, a central pipe, and a water distributor. The valve assembly is disposed at the opening of the housing.

[0041] like Figure 2-6 The water distributor shown includes a lower water distribution structure 1 and an upper water distribution structure 2. The lower water distribution structure 1 and the upper water distribution structure 2 will be described in detail below.
[0042] The lower water distribution structure 1 includes a lower water distribution plate 10 and a lower water distribution pipe 11, with the lower water distribution plate 10 sleeved on the outer periphery of the lower water distribution pipe 11.
[0043] In this embodiment: only a small portion of the upper surface of the lower water distribution pipe 11 protrudes from the upper surface of the lower water distribution plate 10. Wherein:
[0044] The lower water distribution plate 10 has through holes 100 extending through its upper and lower sides. Liquid falls onto the lower water distribution plate 10 and is dispersed, and can flow down through the through holes 100.
[0045] In a preferred embodiment of this invention: A surrounding strip 101 is provided around the lower water distribution tray 10, and a plurality of lower guide strips 102 are provided on the upper surface of the lower water distribution tray 10. One end of each lower guide strip 102 is connected to the outer wall of the lower water distribution pipe 11, and the other end is connected to the surrounding strip 101. A lower guide channel 103 is formed between two adjacent lower guide strips 102, and a through hole 100 is located on the lower water distribution tray 10 within the lower guide channel 103. The liquid is evenly distributed on the lower water distribution tray 10 through the lower guide channel 103, further dispersing the liquid uniformly.
[0046] Preferably, multiple lower guide strips 102 are evenly distributed on the upper surface of the lower water distribution plate 10.
[0047] In another preferred embodiment of this invention, the upper surface of the lower water distribution pan 10 extends downwards at an angle from its center to its periphery. The angled surface guides the liquid, facilitating its diffusion to the edges of the lower water distribution pan 10.
[0048] The lower water distribution pipe 11 has water distribution ports 110 extending through its inner and outer sides on its pipe wall. In this embodiment, the water distribution ports 110 are strip-shaped extending in the vertical direction. In addition, the diameter of the lower water distribution pipe 11 gradually decreases from top to bottom, and the liquid can flow out from the water distribution ports 110 along the inclined pipe wall of the lower water distribution pipe 11.
[0049] The upper water distribution structure 2 includes an upper water distribution plate 20 and an upper water distribution pipe 21, with the upper water distribution plate 20 sleeved on the outer periphery of the upper water distribution pipe 21.
[0050] In this embodiment: the lower end of the upper water distribution pipe 21 does not protrude from the lower surface of the upper water distribution plate 20. Wherein:
[0051] Multiple upper guide strips 210 are provided on the inner wall of the upper water distribution pipe 21, and an upper guide channel 211 is formed between two adjacent upper guide strips 210. Liquid can be dispersed and flow down through the upper guide channel 211.
[0052] After the lower water distribution structure 1 and the upper water distribution structure 2 are connected, the center lines of the lower water distribution plate 10, the lower water distribution pipe 11, the upper water distribution plate 20, and the upper water distribution pipe 21 coincide. The upper water distribution plate 20 covers the lower water distribution plate 10, and the diameter of the upper water distribution pipe 21 is larger than that of the lower water distribution pipe 11, so that the projection of the upper water distribution pipe 21 on the lower water distribution structure 1 is located on the lower water distribution plate 10. That is, the liquid dispersed and flowing down from the upper guide channel 211 can flow onto the lower water distribution plate 10. Furthermore, the lower end of the upper guide channel 211 is directly opposite the lower guide channel 103 of the lower water distribution plate 10, which means that the liquid dispersed and flowing down from the upper guide channel 211 can flow into the lower guide channel 103 of the lower water distribution plate 10.
[0053] The water distributor in this embodiment can be applied to water treatment equipment, such as water softeners and filter tanks.
[0054] Water treatment equipment typically includes a housing 30, a valve assembly, a central pipe 31, and a water distributor 32. The valve assembly is located at the opening of the housing 30. The upper end of the central pipe 31 is connected to the valve assembly, and the lower end of the central pipe 31 extends into the housing 30. The water distributor 32 is located at the opening of the housing 30 and is fitted onto the central pipe 31. The central pipe 31 passes through the upper water distribution pipe 21 and the lower water distribution pipe 11, and there are gaps between the upper water distribution pipe 21, the lower water distribution pipe 11, and the central pipe 31.
[0055] The water treatment equipment features low-flow brine forward flushing mode, high-flow raw water forward flushing mode, and high-flow raw water backflushing mode.
[0056] like Figure 7 As shown: In the low-flow brine forward flushing mode: brine flows from top to bottom through the upper water distribution pipe 21, the lower water distribution plate 10, and the through holes 100. Specifically: the brine flows down through the upper guide channel 211 of the upper water distribution pipe 21, into the lower guide channel 103 on the lower water distribution plate 10, and flows out evenly from the center to the surrounding through holes 100 along the lower guide channel 103, which can slowly and evenly flush the filter media inside the housing 30.
[0057] like Figure 8 As shown: In the high-flow-rate raw water forward flushing mode: a portion of the raw water flows from top to bottom through the upper water distribution pipe 21, the lower water distribution plate 10, and the through hole 100, while the other portion flows from top to bottom through the upper water distribution pipe 21, the lower water distribution pipe 11, and the water outlet 110. Specifically: a portion of the raw water flows down through the upper guide channel 211 of the upper water distribution pipe 21, into the lower guide channel 103 on the lower water distribution plate 10, and flows out evenly from the center to the surrounding through holes 100 along the lower guide channel 103; the other portion of the raw water flows down through the upper guide channel 211 of the upper water distribution pipe 21, into the gap between the lower water distribution pipe 11 and the central pipe 31, and flows out from the water outlet 110. Due to the large water volume, rapid flow can be achieved.
[0058] like Figure 9 As shown: In the high-flow raw water backwash mode: part of the raw water is flushed from bottom to top through the through hole 100, the lower water distribution plate 10, and the upper water distribution pipe 21, while the other part of the raw water is flushed from bottom to top through the water distribution port 110, the lower water distribution pipe 11, and the upper water distribution pipe 21. This is the opposite of the high-flow raw water forward flush mode, and can also achieve rapid circulation.
[0059] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
