Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment device that integrates water purification and softening. Background Technology

[0002] In water treatment systems, water softening equipment removes calcium and magnesium ions from water. Water purification equipment removes residual chlorine, colloids, and impurities from tap water. An integrated water purifier and softener is a single, combined water treatment system that purifies and softens raw water in one unit.

[0003] Existing water purifiers with both water softening and water softening functions require separate pipes for the water softener and the water purifier, resulting in drawbacks such as complex equipment, low integration rate, and large size. Utility Model Content

[0004] The main purpose of this utility model is to provide a water purification and softening water treatment device to solve the problems of complex equipment, low integration and large size in the existing technology.

[0005] To address the aforementioned problems, an embodiment of this utility model proposes a water purification and softening treatment device, comprising: a purified water tank and a softened water tank arranged adjacent to each other, with a first valve body positioned above the purified water tank and a second valve body positioned above the softened water tank; a water system comprising: an inlet and an inlet channel communicating with the inlet, an outlet and an outlet channel communicating with the outlet; the inlet channel and the outlet channel are arranged parallel to each other and are respectively located on opposite sides above the first valve body and the second valve body, the inlet channel communicating with both the first valve body and the second valve body, and the outlet channel communicating with the second valve body; wastewater outlets are respectively connected to the first valve body and the second valve body.

[0006] The water system also includes a purified water outlet, which is located in the water inlet channel between the first valve body and the second valve body.

[0007] The first valve body includes three modes: purification mode, backflushing mode, and forward flushing mode; the water inlet channel includes a first channel above the first valve body and a second channel above the second valve body. The first channel is divided into an inlet section and an outlet section. In purification mode, the raw water passes sequentially through the inlet, the inlet section of the first channel of the water inlet channel, the first valve body, and the outlet section of the first channel of the water inlet channel.

[0008] The first valve body includes a first turntable, which can be selectively rotated between a purification position, a backflushing position, and a forward flushing position, so that the first valve body is in a purification working mode, a backflushing mode, or a forward flushing mode.

[0009] The second valve body includes four modes: softening mode, water injection mode, brine absorption mode, backflushing mode, and forward flushing mode. In the softening mode, the purified water from the first valve body passes through the second valve body and the water outlet channel in sequence.

[0010] The second valve body includes a second turntable, which can be selectively rotated between a softening position, a water injection position, a brine suction position, a backflushing position, and a forward flushing position, so that the second valve body is in a softening mode, a water injection mode, a brine suction mode, a backflushing mode, or a forward flushing mode.

[0011] The water inlet and the water outlet are located on one side of the water purification tank.

[0012] The water inlet channel located above the first valve body is divided into an inlet section and an outlet section by a partition. The two ends of the inlet section are connected to the water inlet and the first valve body, respectively. The two ends of the outlet section are connected to the first valve body and the water inlet channel located above the second valve body, respectively.

[0013] The second valve body is also equipped with an ejector.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Although this utility model specification may include various different embodiments, it should be understood that, with regard to some preferred embodiments described in detail in the specification and shown in the accompanying drawings, the contents disclosed in this utility model specification should be regarded as illustrative of the principles of this utility model, and the embodiments shown are not intended to limit the scope of protection of this utility model.

[0021] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] This utility model provides a water purification and softening device, which integrates water purification and softening into a single unit. (Reference) Figure 1 and Figure 2 The water treatment equipment includes a purified water tank 10 and a softened water tank 20 arranged adjacent to each other. In this application, the raw water (e.g., tap water) is first purified and then softened. The purified water tank may use granular activated carbon as the filter medium to remove residual chlorine, colloids, impurities, and pigments from the tap water; the softened water tank may use sodium carbonate (Na₂O₃) as the filter medium. + This invention uses activated carbon resin as the softening medium to remove calcium and magnesium ions from water. Existing integrated water purifiers and softeners use carbon fiber or carbon rods as the purification medium in the water tank, which can lead to a shortened flow decay cycle and easy clogging of the water circuit. This application uses granular activated carbon as the filter medium, effectively solving the above problems.

[0023] A water purification valve body (i.e., the first valve body) 11 is provided above the water purification tank 10, and a water softening valve body (i.e., the second valve body) 21 is provided above the water softening tank 20. In this embodiment, the valve body (11 or 21) can also be called a valve head, valve core, control valve, etc., and is used to realize multiple modes or the conversion between modes, such as working mode, backflushing mode, forward flushing mode, water injection mode, brine suction mode, etc., which are described in detail below.

[0024] The water system according to this application is integrated in a disc-type interconnected structure above the water purification tank and the water softening tank. The disc-type interconnected water system includes pipes connected to valve bodies 11 and 21, and mainly includes: inlet channels 32 and outlet channels 34 arranged parallel to each other above valve bodies 11 and 21 on both sides. The inlet channels 32 are connected to both valve bodies 11 and 21. Further, the inlet channels 32 may include a first section above valve body 11 and a second section above valve body 21. The first section is connected to a raw water inlet 31, which is used to connect to raw water. In this embodiment, the first section is divided into an inlet section and an outlet section by a partition, which may be located in the middle of the first section or near it. The two ends of the inlet section are connected to the inlet 31 and the first valve body 11, respectively, and the two ends of the outlet section are connected to the first valve body 11 and the second section, respectively. The first channel above the valve body 11 is divided into two sections to allow raw water to enter the water purification tank 10 through the valve body 11, and for the purified water to continue entering the inlet channel for further softening. A purified water outlet 35 can be provided between the first and second channels for the purified water (without softening treatment) to flow out.

[0025] According to the embodiments of this application, the two ends of the water outlet channel 34 are connected to the valve body 21 and the soft water outlet 33, respectively, and the water outlet channel 34 is not connected to the valve body 11. That is to say, the softened water after softening treatment flows directly to the outlet 33. Similarly, the water outlet channel 34 may also include a third channel located above the valve body 21 and a fourth channel located above the valve body 11, and these two channels are connected. Figure 1 The direction of the arrow in the dashed line segment shown indicates the direction of water flow in the working state. In practical applications, the first and fourth channels can be integrally formed with a part of the valve body 11 (e.g., valve seat); the second and third channels can be integrally formed with a part of the valve body 21 (e.g., valve seat).

[0026] In this embodiment, valve body 11 and valve body 21 have largely similar structures, and both valve body 11 and valve body 21 can realize operating modes, backflushing modes, and forward flushing modes; the difference is that valve body 21 also includes a water injection mode and a brine suction mode. That is, valve body 21 has passages for water injection and brine suction. (Reference) Figure 1 The valve body 21 also includes an ejector 38, which may be a Venturi ejector, connected to an external salt tank, for regenerating the resin by drawing in brine through the salt tank.

[0027] refer to Figure 3The structure of the valve body according to this application embodiment is described below using valve body 11 as an example. Valve body 11 mainly includes, from top to bottom: motor 41, motor bracket 42, gear 43, micro switch 44, valve cover 45, wastewater outlet 46, turntable 47, and valve seat 48. The motor bracket 42 is used to mount the motor 41. The gear 43 is disposed within the motor bracket 42 and connected to the motor 41. The gear 43 has multiple positions corresponding to different working states. The micro switch 44 is used to switch the motor signal on and off through the gear 43 and is fixed to the valve cover 45. The valve cover 45 covers the turntable 47 and has a wastewater outlet channel and wastewater outlet 46. The turntable 47 is disposed above the valve seat 48. The valve seat 48 can be integrated with the water inlet channel and water outlet channel of the water system. The turntable 47 rotates synchronously with the gear 43, allowing the turntable 47 to be in different positions. For example, corresponding to valve body 11, turntable 47 has three positions: purification position, backflushing position, and forward flushing position; or corresponding to valve body 21, turntable 47 has five positions: softening position, water injection position, brine suction position, backflushing position, and forward flushing position. Turntable 47 has multiple openings to correspond to the water flow path in different position modes. A wastewater outlet is also located in the center of turntable 47. Valve seat 48 includes multiple valve chambers that can be connected to water passages that perform different functions of the tank (e.g., inlet and outlet). When turntable 46 rotates with gear 43, it can connect the external water system to the internal water system according to the selected function, thereby achieving different functions. It should be noted that, to save costs, valve body 11 can be manufactured according to the standard of valve body 21. In practical applications, unnecessary functions of valve body 11 can be disabled, such as preventing the gear of valve body 11 from stopping at the water injection and brine suction positions.

[0028] The water flow direction in various modes is described in detail below. When both valve body 11 and valve body 21 are in working mode, raw water flows from inlet 31 into the inlet section of the first channel of inlet channel 32 and enters valve body 11. Valve body 11 guides the raw water into the water purification tank 10 and purifies it through a medium. The purified water then enters valve body 11, which guides it into the outlet section of the first channel, then into the second channel of inlet channel 32, and finally into valve body 21. Valve body 21 guides the purified water into the water softening tank 20 and softens it through a medium. The softened water then enters outlet channel 34 and flows out from outlet 33. In this application, the complete workflow includes purification and softening processes, and the softened water is the water after purification and softening. The water flow direction can be referred to... Figure 1 The arrow direction of the dashed line segment shown.

[0029] When valve body 11 is in backwash (washing) mode, the activated carbon filter media is flushed by reverse water flow to remove suspended solids and impurities adhering to the surface of the filter media. Raw water flows into the inlet section of the first channel of the inlet channel 32 through inlet 31 and enters valve body 11. Valve body 11 guides the raw water from the outlet in the middle of the water purification tank into the water purification tank 10 and flushes the filter media from bottom to top. The generated wastewater enters valve body 11 upward through the water purification tank inlet and is guided by valve body 11 to the wastewater outlet 36 for discharge.

[0030] When valve body 11 is in forward flushing (washing) mode, the activated carbon filter media is flushed by forward water flow to remove fine particles and loose impurities. Raw water flows into the inlet section of the first channel of the inlet channel 32 through inlet 31 and enters valve body 11. Valve body 11 guides the raw water from the inlet of the water purification tank into the water purification tank 10 and flushes the filter media from top to bottom. The generated wastewater enters valve body 11 from the outlet in the middle of the tank and is then guided by valve body 11 to the wastewater outlet 36 for discharge.

[0031] When valve body 21 is in backwash (washing) mode, the resin filter media is flushed by reverse water flow to remove particulate matter and impurities, or to loosen the resin layer. Specifically, purified water enters valve body 21 through the second section of inlet channel 32, and valve body 21 guides the purified water from the outlet in the middle of the tank into the soft water tank 20 to flush the filter media from bottom to top. The generated wastewater enters valve body 21 upward through the soft water tank inlet, and is then guided by valve body 21 to the wastewater outlet 37 for discharge.

[0032] When valve body 21 is in forward flushing (washing) mode, the resin filter media is flushed by a forward water flow to remove residual brine and calcium and magnesium ions. Specifically, purified water enters valve body 21 through the second section of inlet channel 32, and valve body 21 guides the purified water from the inlet of the purified water tank into the soft water tank 20 to flush the filter media from top to bottom. The generated wastewater enters valve body 21 from the outlet in the middle of the tank and is then guided by valve body 21 to the wastewater outlet 37 for discharge.

[0033] When the valve body 21 is in the salt suction mode, it is connected to the external salt tank through the ejector 38 to draw the salt solution in the salt tank into the soft water tank 20 to regenerate the resin.

[0034] When the valve body 21 is in the water injection mode, softened water can be injected into the salt tank through the ejector 38 to dissolve the salt in the salt tank into a high-concentration brine.

[0035] According to the technical solution of this utility model, the inlet and outlet channels, inlet, and outlet of the water purification tank and the water softening tank are highly integrated through an integrated disc-type interconnected water system, realizing multiple functions of water purification and softening treatment. It has the advantages of compact structure, small size, and high integration. Furthermore, by using granular activated carbon as the filter medium of the water purification tank, the flow decay cycle is not shortened, and the water circuit is not easily blocked.
