Abstract

This application provides a desalination and descaling device for tap water treatment, relating to the field of tap water treatment technology. The device includes a tank with an inlet cap and an outlet cap detachably mounted at both ends. A filter assembly is coaxially inserted inside the tank, with one end of the filter assembly facing the outlet cap sealed to the tank. The filter assembly has an open end at its axial center facing the outlet cap. A power component is coaxially inserted into the filter assembly, using water flow to drive a conical baffle to rotate, ensuring even water distribution within the tank. Protrusions on the filter assembly cause the conical baffle to reciprocate axially, creating a tapping motion that vibrates the filter structure, reducing clogging by scale and other debris. The detachable design at both ends of the tank facilitates filter assembly replacement, improving filtration efficiency.

Description

Technical Field

[0001] This application relates to the field of tap water treatment technology, and more specifically, to a desalination and descaling device for tap water treatment. Background Technology

[0002] In the prior art, such as the automatic descaling deep water treatment device for water plants disclosed in CN218046849U, there are self-filtering boxes, input mechanisms, and output mechanisms, as well as filtration mechanisms and descaling mechanisms. The input mechanism is located at one end of the filter box, the filtration mechanism is located inside the filter box, the descaling mechanism is located below the filtration mechanism, and the output mechanism is located at the other end of the filter box. The filter plate in the device is equipped with a first spring at one end. In this design, when the filter plate is blocked by dirt during tap water filtration, the water pressure at one end of the filter plate will increase, pushing the filter plate to one end. After the filter plate moves, the descaling blades will have room to rotate. A low-speed motor drives the descaling blades to descale the filter plate. In this way, the device can clean the filter plate when it needs to be cleaned, minimizing the impact on the efficiency of tap water filtration and reducing unnecessary power consumption.

[0003] However, while this solution prevents the filter plates from becoming clogged by dirt and ensures the filtration efficiency of tap water, the scale inside the holes on the filter plates cannot be cleaned, and will still cause clogging after prolonged use.

[0004] Secondly, as disclosed in CN207792895U, a device for desalination and descaling of tap water includes a tap water pipe, a filter device, and a desalination device. The tap water pipe is connected to the filter device, which is connected to the desalination device via a connecting pipe. The desalination device includes a reaction tank with a water distribution plate connected to the connecting pipe at the top. An anion exchange resin layer, a layered resin layer, a cation exchange resin layer, and a reverse osmosis membrane layer are stacked sequentially from top to bottom inside the reaction tank. All layers are funnel-shaped. A regenerated liquid discharge pipe passes through the anion exchange resin layer, the layered resin layer, and the cation exchange resin layer sequentially at the center of the reaction tank. This solution combines reverse osmosis and ion exchange, resulting in high desalination quality, high desalination efficiency, high filtration efficiency, and descaling capabilities. However, its design is complex, requiring multiple processes for repeated filtration and desalination of the tap water. Regular chemical cleaning of the materials within the processes is also necessary to prevent a decline in the device's desalination and descaling functions. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a desalination and descaling device for tap water treatment, aiming to improve upon the shortcomings of existing desalination and descaling devices for tap water treatment, such as the inability to alleviate clogging caused by dirt and the complexity of the process requiring regular cleaning.

[0006] This application discloses a desalination and descaling device for tap water treatment, comprising a tank body, with an inlet end cap and an outlet end cap detachably installed at both ends of the tank body, and a filter plate coaxially arranged inside the outlet end cap; a filter assembly is coaxially inserted inside the tank body, the filter assembly having at least three layers coaxially arranged, all three layers of the filter assembly having a hollowed-out sidewall, the end of the filter assembly facing the outlet end cap being sealed and inserted into the tank body, and the layer of the filter assembly located at the axial center being open at the end facing the outlet end cap; a power assembly is coaxially inserted into the filter assembly, the power assembly including a conical baffle rotatably connected to the filter plate, the conical baffle being located at the end of the filter assembly facing the inlet end cap, the conical baffle being axially elastically displaced relative to the filter assembly, the conical baffle being rotatably connected to the filter assembly, and the end of the filter assembly facing the conical baffle having a plurality of protrusions evenly arranged.

[0007] According to an embodiment of this application, a desalination and descaling device for tap water treatment has the following advantages: the water flow entering through the inlet cap drives the conical baffle to rotate, making the water evenly distributed in the tank and entering from the side of the filter assembly, seeping out from the axis of the filter assembly and flowing out from the open end of the axis of the filter assembly. When the water flow drives the conical baffle to rotate, the protrusions on the filter assembly cause the conical baffle to undergo axial reciprocating elastic displacement, forming a knocking action on the filter assembly. This causes the filter structure inside the filter assembly to vibrate, reducing the phenomenon of scale and other debris clogging the filter material and extending the service life of the filter assembly. At the same time, the design of detachable ends of the tank facilitates the replacement of the filter assembly and improves the filtration effect.

[0008] In addition, a desalination and descaling device for tap water treatment according to an embodiment of this application also has the following additional technical features:

[0009] In some specific embodiments of this application, the filter assembly is coaxially provided with an outer layer, an inner layer and a core layer, the outer layer is embedded with filter particles, the inner layer is embedded with desalination particles, and the core layer is unfilled.

[0010] In some specific embodiments of this application, an outer cover is detachably installed on the side of the outer layer facing the conical spoiler, an inner cover is detachably installed on the side of the inner layer facing the conical spoiler, the side of the core layer facing the conical spoiler is sealed, and a plurality of protrusions are uniformly arranged circumferentially on one end of the core layer facing the conical spoiler.

[0011] In some specific embodiments of this application, the ridges are distributed radially, and the sidewalls of the ridges are arranged in an arc shape.

[0012] In some specific embodiments of this application, a positioning shaft is coaxially and movably inserted into the conical baffle, and the positioning shaft is movably inserted into the filter assembly and rotatably connected to the filter plate.

[0013] In some specific embodiments of this application, a fixing ring is fixedly connected to one end of the positioning shaft facing the water inlet end cover. The fixing ring is rotatably fitted into the water inlet end cover, and a plurality of through holes are evenly provided on the fixing ring.

[0014] In some specific embodiments of this application, the conical baffle has a plurality of arc-shaped blades evenly arranged circumferentially at one end facing the water inlet end cap, and a connecting ring is coaxially fixed to one end of the conical baffle facing the filter assembly. A plurality of disturbance rods are evenly fixed circumferentially on the inner wall of the connecting ring, and the plurality of disturbance rods and the plurality of protrusions slide against each other.

[0015] In some specific embodiments of this application, a flange is coaxially provided on the positioning shaft, and a spring is sleeved on the positioning shaft, with the two ends of the spring abutting against the fixing ring and the flange, respectively. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-4 As shown, a desalination and descaling device for tap water treatment according to an embodiment of this application includes a tank 1. An inlet end cap 11 and an outlet end cap 12 are detachably installed at both ends of the tank 1. A filter plate 13 is coaxially arranged inside the outlet end cap 12. It should be noted that the inlet end cap 11 and the outlet end cap 12 can be sealed at both ends of the tank 1 by means of threads or quick release, so as to facilitate the installation or removal of the inlet end cap 11 and the outlet end cap 12.

[0024] The tank 1 contains a filter assembly 2 coaxially inserted inside. The filter assembly 2 has at least three layers coaxially arranged, and all three layers have open sidewalls. The end of the filter assembly 2 facing the outlet cap 12 is sealed to the tank 1, while the layer at the axial center of the filter assembly 2 is open at the outlet cap 12. Specifically, as shown... Figure 2 and Figure 3As shown, the filter assembly 2 is coaxially arranged with an outer layer 21, an inner layer 22, and a core layer 23. The outer layer 21 is filled with filter particles, the inner layer 22 is filled with desalination particles, and the core layer 23 is unfilled. It should be noted that the filter particles can be activated carbon or other particles with the function of adsorbing impurities, and the desalination particles can be cation exchange resin and anion exchange resin particles (the cation exchange resin is located on the periphery of the anion exchange resin). Thus, water enters the outer layer 21 from the outer wall of the filter assembly 2, where the activated carbon particles intercept the impurities. The filtered water then enters the inner layer 22 radially from the outer layer 21, where the cation exchange resin and anion exchange resin particles remove the salt from the water. After that, the water enters the core layer 23 radially, and under the action of water flow pressure, it passes through the filter plate 13 from the open end of the core layer 23 and is discharged from the outlet end cover 12.

[0025] It should be noted that the outer layer 21 has an outer cover 211 detachably installed on the side facing the conical baffle 31, and the inner layer 22 has an inner cover 221 detachably installed on the side facing the conical baffle 31. This design facilitates the replacement of the internal filter material. At the same time, the sealing design forces the water flow to enter the interior only from the radial direction of the filter assembly 2. The axial layer 23 is sealed on the side facing the conical baffle 31, and multiple protrusions 231 are evenly arranged circumferentially on one end of the axial layer 23 facing the conical baffle 31. The protrusions 231 are distributed radially, and the sidewalls of the protrusions 231 are arc-shaped.

[0026] like Figure 2 and Figure 4As shown, a power assembly 3 is coaxially inserted into the filter assembly 2. The power assembly 3 includes a conical baffle 31 rotatably connected to the filter plate 13. The conical baffle 31 is located at the end of the filter assembly 2 facing the inlet cap 11. The conical baffle 31 has an axial elastic displacement relative to the filter assembly 2. The conical baffle 31 and the filter assembly 2 are rotatably connected. Specifically, a positioning shaft 33 is coaxially movably inserted into the conical baffle 31. The positioning shaft 33 is movably inserted into the filter assembly 2 and rotatably connected to the filter plate 13. It can be understood that the rotation of the positioning shaft 33 will not interfere with the filter assembly 2. A fixing ring 32 is fixedly connected to the end of the positioning shaft 33 facing the inlet cap 11. The fixing ring 32 is rotatably fitted into the inlet cap 11, and multiple through holes are evenly arranged on the fixing ring 32 to facilitate water passage. The conical baffle 31 faces the inlet cap 11. Multiple arc-shaped blades are evenly arranged around one end of the water inlet cap 11. It can be understood that after the water flows in from the water inlet cap 11, it will impact the blades. Due to the conical design of the conical baffle 31, the water flows radially towards the side wall of the filter assembly 2. After the blades are impacted, the entire conical baffle 31 will rotate. At this time, the water will form a circulation between the tank 1 and the filter assembly 2. This will make the water evenly distributed in the tank 1, further improving the water treatment efficiency of the filter assembly 2 and avoiding a decrease in the local water treatment capacity of the filter medium inside the filter assembly 2 (when the water passes through the filter assembly 2 radially, if the water does not form a circulation, it is very easy for the water passage near the water inlet cap 11 to be less than the water passage near the water outlet cap 12).

[0027] The conical baffle 31 is coaxially fixed to a connecting ring 311 at one end facing the filter assembly 2. Multiple baffle rods 312 are uniformly fixed circumferentially to the inner wall of the connecting ring 311. These baffle rods 312 slide against multiple protrusions 231. A flange 331 is coaxially mounted on the positioning shaft 33, and a spring 34 is sleeved on the positioning shaft 33. The two ends of the spring 34 abut against the fixing ring 32 and the flange 331, respectively. Therefore, when the conical baffle 31 rotates under the influence of water flow, it will cause the multiple baffle rods 312 to rotate synchronously and in the same direction. Due to the elastic force of the spring 34, initially, the baffle rods 312 abut against the sealing end face of the core layer 23 before touching the protrusions 231. During rotation, the baffle rods 312 will slide against the protrusions 231. This is due to the arc-shaped design of the protrusions 231. This will force the conical baffle 31 to move axially away from the sealing end face of the core layer 23. Under the elastic force of the spring 34, after the baffle rod 312 passes the protrusion 231, the conical baffle 31 will move axially closer to the sealing end face of the core layer 23. In this way, the frequent axial reciprocating movement will cause the conical baffle 31 to strike the sealing end face of the core layer 23. The vibration generated by the striking will cause the particles in the filter assembly 2 to vibrate, which will reduce the clogging caused by scale, impurities, etc., and improve the efficiency of the filter assembly 2 for water treatment to a certain extent. At the same time, there is no need for a separate power supply design, which reduces the cost of water treatment. The design of the removable end caps at both ends and the design of the removable sealing cap on the filter assembly 2 will make it easy to replace the particles in the filter assembly 2 and improve the water treatment effect.

[0028] It should be noted that the specific model and specifications of spring 34 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0029] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
