Description

Technical Field

[0001] The invention relates to the field of water treatment, in particular to a water distributor for a resin tank of a water softener. Background Art

[0002] "Water distribution" means arranging water flow in a certain working area according to a certain rule. The most common method is to evenly distribute water on the working surface. The device that completes this task is called a water distributor. In the field of water treatment, in order to evenly distribute water in water treatment equipment (such as water softeners and water purifiers), an adapter water distributor is installed in the water storage container of the water treatment equipment (such as a fiberglass reinforced plastic water treatment tank) to collect and distribute water. Generally, there are upper water distributors and lower water distributors.

[0003] As people's living standards improve, the inconvenience and excessive living costs caused by water hardness are increasingly valued by the general public. A water softener is a special device used to remove the hardness in water. It has a built-in softening resin. After hard water passes through the resin bed, the hardness cost (component) in the water is adsorbed on the resin bed through an exchange reaction, so the output water no longer contains hardness.

[0004] In the prior art, a water softener structure includes: a control valve, a resin tank, a salt box, a salt valve and other components. The control valve is installed in the interface of the upper port of the resin tank, and the resin tank is also built with a resin bed, an upper water distributor, a water pipe, a lower water distributor and other components. Usually, the resin tank is in the shape of a cylinder, and is connected to the control valve at the upper end (such as a threaded connection). This resin tank and connection method are mature in technology, low in cost, high in connection strength, and have a low failure rate, so they are widely used. However, the disadvantage of this resin tank is that the diameter of the mouth connected to the control valve is small, which limits the size of the water distributor. When the diameter of the tank body is large, the diameter of the resin tank mouth will not increase with the diameter of the tank body, and the size of the water distributor that can be arranged through the resin tank mouth will not match the tank body.

[0005] In actual use, the specific manifestation of the above mismatch in the water softener is low regeneration efficiency and failure to achieve the ideal resin bed regeneration level.

[0006] Therefore, technicians have developed a variety of technologies to try to break through the size of the water distributor. Chinese patent CN221141371U discloses a flat water distributor for a water softener resin tank. The water distributor (flat water distributor) is designed to be almost the same size as the inner diameter of the resin tank, and the opening on the resin tank is designed to be consistent with the size of the water distributor, thus achieving a technical breakthrough. However, this technology greatly increases the difficulty of manufacturing the resin tank, and the pressure-bearing capacity of the resin tank is greatly reduced, so it is not a good solution.

[0007] Chinese patent CN221739929U discloses a water distributor, including an upper water distributor and a lower water distributor mounted on a central tube, wherein the upper water distributor includes: a base formed in a bowl shape with the mouth of the bowl facing upward, which is fixed on the upper half of the central tube, and a first connection port for the central tube to pass through is formed in the center of its bottom wall; a plurality of second connection ports are evenly arranged around the first connection port; the tops of a plurality of connection parts with the same structure and shape are respectively connected to the second connection ports, and a third connection port is formed on the bottom side wall; a first connection piece is formed on the side wall of the connection part opposite to the third connection port, a fourth connection port connected to the third connection port is formed on one end side wall of a plurality of water distribution grippers with the same shape, and uniform water distribution holes are formed on the water distribution gripper body and the water distribution gripper plug; a second connection piece is formed on the side wall of the water distribution gripper opposite to the fourth connection port, and is used in conjunction with the first connection piece. This scheme retains the structure of the barrel + valve, and innovates on the basis of the existing diameter of the resin tank mouth. Its underlying logic is to expand the water distribution surface to achieve the water flow effect of the flat water distributor, so as to achieve the effect of improving the resin utilization rate. However, this type of technology makes the water distributor too complicated. It either needs to be assembled in a barrel or designed as a folding structure, which greatly increases the difficulty of assembly, so it is not a good solution. Summary of the invention

[0008] A series of simplified concepts are introduced in the Summary of the Invention, which are all simplifications of the prior art in the field, and will be further described in detail in the Detailed Description of the Invention. The Summary of the Invention of the present invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0009] The technical problem to be solved by the present invention is to provide a water distributor which can improve the water permeability efficiency of the resin bed and thus enhance the utilization rate of the resin bed without increasing the size of the water distributor.

[0010] It should be noted that the improvement of the water permeability of the resin bed without increasing the size of the water distributor means: under the premise that the diameter of the resin tank is the same and the water distributor can enter the resin tank through the resin tank opening for installation, the water permeability of the resin bed is improved without increasing the size of the water distributor.

[0011] In order to solve the above technical problems, the present invention provides a water distributor, which is used for a water softener resin tank, comprising:

[0012] The upper water distributor 1 is connected to the lower port of the water softener control valve and is formed into an inner and outer double-layer structure, and its outer diameter is smaller than the inner diameter of the resin tank port;

[0013] After the water outlet of the control valve passes through the inner layer of the upper water distributor 1, the water flow is changed to a non-vertical direction and passes through the outer layer of the water distributor 1 to form a spray distribution.

[0014] Preferably, the water distributor is further improved, and the upper water distributor 1 comprises:

[0015] A first connecting member 1.1, which is connected to the lower port of the water softener control valve;

[0016] The first set 1.2 is formed into a first bowl-shaped structure, and the mouth of the first bowl-shaped structure is fixedly connected to the first connecting member 1.1;

[0017] A first water hole 1.4, which is formed on the upper half of the side wall of the first set 1.2;

[0018] The second set 1.3 is fixed from bottom to top on the outside of the first set 1.2;

[0019] The second water through hole 1.5 is formed on the side wall of the second sleeve 1.3.

[0020] Optionally, the first water through hole 1.4 and the second water through hole 1.5 are holes of different shapes.

[0021] Preferably, the water distributor is further improved, the first water hole 1.4 is a circular hole, and the second water hole 1.5 is a vertical strip hole; the present invention uses holes of different shapes, especially the inner layer uses a larger circular hole feature, in order to increase the flow rate and reduce the pressure loss.

[0022] Preferably, the water distributor is further improved, and the lower part of the second set 1.3 is welded and fixed to the lower part of the first set 1.2;

[0023] Or, the lower part of the second set 1.3 is fixed to the lower part of the first set 1.2 by gluing;

[0024] Alternatively, the lower portion of the second set 1.3 is fixed to the lower portion of the first set 1.2 via a second connecting member 1.6.

[0025] Preferably, the water distributor is further improved to include:

[0026] The water delivery pipe 2, the upper end of which is connected to the central hole of the control valve through the upper end;

[0027] The lower water distributor 3 is fixedly connected to the lower port of the water delivery pipe 2, and its outer diameter is smaller than the inner diameter of the resin tank mouth, forming an inner and outer double-layer structure to distribute the water flow downward.

[0028] It should be further explained that the water delivery pipe 2 is allowed to move up and down in the water distributor 1 .

[0029] Preferably, the water distributor is further improved, and the lower water distributor 3 comprises:

[0030] The third set 3.1 is formed into an inverted third bowl-shaped structure, the upper port of which is connected to the lower port of the water pipe 2, and a plurality of third water holes are formed on the bowl body of the third bowl-shaped structure;

[0031] The fourth set 3.2 is arranged in the third set 3.1 and is formed into an inverted fourth bowl-shaped structure. A plurality of fourth water holes are formed on the bowl body of the fourth bowl-shaped structure, and an extension portion 3.2.1 is formed on the bowl mouth;

[0032] The mouth of the third bowl-shaped structure is buckled and fixed on the extension part 3.2.1.

[0033] Preferably, the water distributor is further improved to include:

[0034] A third connecting member 3.1.1, which is formed at the bottom of the extension portion 3.2.1 and is used to connect and fix the bottom wall of the resin tank;

[0035] The fifth set 3.3 is mounted on the third set 3.1 and is formed into an inverted fifth bowl-shaped structure. The mouth of the fifth bowl-shaped structure is higher than the mouth of the third bowl-shaped structure and guides the water flowing out of the third set 3.1 downward.

[0036] Further explanation, the fifth kit 3.3 is the outer layer, and the third kit 3.1 and the fourth kit 3.2 are the inner layers, which together form an inner and outer double-layer structure of the lower water distributor. The inner layer collects water and isolates the filter material, while the outer layer changes the water flow and lowers the water flow.

[0037] Preferably, the water distributor is further improved, and a receiving recess 3.2.2 is formed at the position where the upper port of the fourth set 3.2 is directly opposite to the lower port of the water pipe 2;

[0038] A plurality of fourth water holes are formed on the receiving recess 3.2.2.

[0039] Among them, the third water through hole and the fourth water through hole are vertical strip holes.

[0040] Preferably, the water distributor is further improved, the extension 3.2.1 is formed as a horizontal extension, and a blocking protrusion 3.2.1.1 is formed on its edge;

[0041] The blocking protrusion 3.2.1.1 prevents the third set 3.1 from radially separating from the extension 3.2.1.

[0042] Preferably, the water distributor is further improved, further comprising: the upper water distributor 1 is any one of the upper water distributors 1 described above;

[0043] The upper end of the water delivery pipe 2 passes through the upper water distributor 1 and is inserted into the central hole of the control valve.

[0044] The design of the upper water distributor in the prior art is similar to the design of the lower water distributor in the prior art. Both have an array of narrow slit features set on a conical surface of a certain height to ensure that water can pass through, while the resin particles of the resin bed can prevent the water from passing through. The upper water distributor in the prior art has a similar defect. The hard water coming down from the control valve directly rushes to the lower end of the upper water distributor, and then directly penetrates the narrow slit and enters the resin bed. It can be imagined that when the height of the resin bed is relatively high, the lower end of the water distributor directly penetrates the narrow slit and enters the resin bed. It can be imagined that when the height of the resin bed is relatively high, a lot of resin will be wasted and will not participate in the exchange reaction, and then there will be a problem that although a lot of resin is filled, the corresponding water production amount cannot be obtained.

[0045] The present invention designs the structure of the water distributor. On the basis of the original water distributor structure, the concept of "guardrail" is introduced to guide the water flow, specifically:

[0046] The upper water distributor introduces an inner guardrail (first set), and the diversion channel of the inner guardrail is arranged at the upper part. The inner guardrail introduced in the present invention can solve the problem that the resin bed is too high and wastes a lot of resin without participating in the exchange reaction. After the water coming down from the control valve fills the cavity of the inner guardrail (first set) through the water distribution pipeline, it is sprayed out from the water holes (first water holes) on all sides. After encountering the narrow gap (second water holes) of the upper water distributor, it is further decomposed into fine water columns to form a spray effect and reach the top of the resin bed. Thereafter, due to the effect of water pressure, the water enters the resin bed, and the water that completes the exchange reaction after passing through the resin bed becomes soft water and is collected by the lower water distributor on the lower end surface (the lower edge of the outer guardrail of the lower water distributor, that is, the horizontal extension).

[0047] An outer guardrail (the fifth kit) is designed for the lower water distributor to minimize the height of water entering and exiting the lower water distributor. This is because the lower water distributors in the prior art often have narrow slit features in an array and are arranged at a certain height. Therefore, water often passes directly through the narrow slit at the upper port instead of going to the narrow slit below, resulting in the resin bed between the heights of the water distributor not actually participating in the exchange reaction. Therefore, the lower water distributor with an outer guardrail can drain the water downward while ensuring the water flux, allowing the resin bed to fully participate in the exchange reaction.

[0048] It should be noted that the present invention allows the upper water distributor and the lower water distributor to be used independently, and the combined use effect is better. Because the upper and lower water distributors work together, the resin bed can be maximized to participate in the exchange reaction. Without increasing the outer diameter of the water distributor, the utilization rate of the resin bed can be improved, and the purpose of improving the efficiency of the water softener can be achieved.

[0049] Furthermore, the regeneration is carried out in reverse, which can also allow the regeneration liquid to contact the entire resin bed as much as possible, thereby greatly improving the regeneration efficiency and thus improving the performance of the water softener.
