Description

Technical Field

[0001] This invention belongs to the field of water purification technology, and in particular relates to a water purification tank and a drinking water purification and preservation system. Background Technology

[0002] The existing water purification system includes a raw water supply unit, a raw water purification unit, a water-air mixer, a water-air mixing pump, a purified water tank, an ozone generator, an air pump, and an air purification system. The raw water supply unit, raw water purification unit, water-air mixer, and water-air mixing pump are connected sequentially. The purified water tank includes a tank body with an inlet and an outlet. The inlet of the purified water tank is connected to the outlet of the water-air mixing pump. The raw water supply unit is connected to the inlet of the water-air mixer through the raw water purification unit. The air purification system is connected to the air pump, which is connected to the air inlet of the ozone generator. The outlet of the ozone generator is connected to the air inlet of the water-air mixer. The air purification system is connected to the air inlet of the purified water tank.

[0003] The raw water supply unit provides raw water, which is then purified by the raw water purification unit. After being mixed with ozone by a water-air mixer, the ozone water is output to the purified water tank. The water stored in the purified water tank is then supplied as drinking water through the water supply network / water collection device.

[0004] The existing water purification tanks are single-unit tanks, which leads to the following problems:

[0005] An ozone generator takes at least ten seconds to generate the designed ozone concentration from startup. During the initial startup of existing water purification systems, the ozone concentration is insufficient to meet sterilization requirements, meaning the water entering the purification tank is not adequately sterilized. Since the existing purification tank is a single unit, the unsterilized water directly enters the tank, mixes with existing drinking water, and contaminates the water.

[0006] When the water purification system malfunctions or the water supply is interrupted, and the system is restarted after troubleshooting or when the water supply is restored, there is still a problem in the initial stage of water production: the ozone concentration may not meet the sterilization and disinfection requirements. Water that has not been sufficiently sterilized and disinfected may enter the water purification tank, mix with the original drinking water, and pollute the water body.

[0007] During the initial startup and restart phases of the water purification system, there may be insufficiently sterilized water in a single water purification tank. This insufficiently sterilized water may enter the water purification tank and mix with the existing drinking water, causing water pollution.

[0008] Existing single water purification tanks cannot guarantee long-term water quality preservation and cannot provide consistently high-quality purified water. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a water purification tank and a drinking water purification and preservation system. This system can prevent water that has not been adequately sterilized and disinfected from mixing with the existing drinking water and contaminating the water body, and can provide long-term, stable, high-quality purified water.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] A water purification tank includes a transition water purification tank, a multi-functional water purification tank, and a valve assembly;

[0012] The transition water purification tank is located on the top plate of the multi-functional water purification tank;

[0013] The valve assembly is perpendicular to the top plate of the transition water tank.

[0014] The valve assembly includes a motor, a valve stem, a moving valve plate, and a stationary valve plate;

[0015] The motor is located on the upper part of the top plate of the transition water tank. The motor is connected to the first end of the valve stem. The second end of the valve stem is fixed in the valve stem fixing groove in the middle of the moving valve plate. The fixed valve plate is located below the moving valve plate. The fixed valve plate is set in the valve plate fixing seat welded to the edge of the valve assembly mounting hole on the bottom plate of the transition water tank.

[0016] The motor drives the valve stem to rotate the moving valve plate;

[0017] The movable valve plate is provided with a movable valve hole, and the fixed valve plate is symmetrically provided with a first fixed valve hole and a second fixed valve hole;

[0018] The transition water purifier drain pipe and the multi-functional water purifier inlet pipe are welded to the bottom of the valve plate fixing seat; the multi-functional water purifier inlet pipe extends into the bottom of the multi-functional water purifier, and the transition water purifier drain pipe extends out of the bottom of the multi-functional water purifier.

[0019] The first fixed valve hole is connected to the inlet pipe of the multi-functional water purifier tank, and the second fixed valve hole is connected to the outlet pipe of the transition water purifier tank.

[0020] When the moving valve plate rotates, the moving valve hole is connected to the first fixed valve hole, or connected to the second fixed valve hole, or located in other positions of the fixed valve plate and not connected to the first fixed valve hole or the second fixed valve hole.

[0021] This invention controls the drainage of the transition water purifier tank and the inflow of water into the multi-functional water purifier tank via a valve assembly. When the ozone concentration is insufficient for sterilization and disinfection, and the water entering the transition water purifier tank is not adequately sterilized, the moving valve disc is rotated to disconnect the moving valve orifice from the first and second fixed valve orifices. This prevents the transition water purifier tank from draining and the multi-functional water purifier tank from inflowing, thus controlling the residence time of the ozone-contaminated water in the transition water purifier tank. In the transition water purifier tank, the initially purified water undergoes an ozone concentration increase, achieving the desired ozone sterilization and disinfection effect before entering the multi-functional water purifier tank. This prevents incompletely sterilized water from mixing with the existing drinking water, thus improving the sterilization and disinfection effect of the water.

[0022] When the water level in the transition water tank exceeds the high water level and the water in the transition water tank still does not meet the water quality requirements, rotate the moving valve plate to connect the moving valve hole to the second fixed valve hole. The water in the transition water tank will be discharged through the transition water tank drain pipe, lowering the water level in the transition water tank and reducing the amount of water in the transition water tank that does not meet the sterilization and disinfection requirements. Ozone-containing water will continue to enter the transition water tank.

[0023] When the water in the transition water tank meets the water quality requirements, rotate the moving valve plate to connect the moving valve hole with the first fixed valve hole. The water in the transition water tank then enters the multi-functional water tank through the multi-functional water tank inlet pipe for subsequent use.

[0024] This invention can provide long-term, stable, high-quality purified water, preventing water that has not been thoroughly sterilized and disinfected from mixing into the multi-functional water purification tank and contaminating the existing drinking water, thus ensuring the drinking water quality of the remote high-quality drinking water delivery mode water purification system.

[0025] Furthermore, a gasket is provided between the fixed valve plate and the valve plate fixing seat, and the fixed valve plate is disposed in the fixed valve plate mounting groove of the gasket;

[0026] The gasket is symmetrically provided with a first gasket hole and a second gasket hole. The first gasket hole is connected to the first fixed valve hole and the inlet pipe of the multi-functional water purifier tank, and the second gasket hole is connected to the second fixed valve hole and the drain pipe of the transition water purifier tank.

[0027] The gasket secures the valve plate, preventing it from shifting. It also seals any gaps between the valve assembly and the valve assembly mounting holes on the bottom and top plates of the transition water tank, preventing incompletely sterilized water from flowing into the multi-functional water tank and contaminating it.

[0028] Furthermore, a first protrusion is provided in the mounting groove of the fixed valve plate, and a recess is provided on the fixed valve plate, with the first protrusion engaging with the recess. This limits the position of the fixed valve plate and prevents it from moving.

[0029] Furthermore, the inlet pipe of the multi-functional water purifier includes an inner inlet pipe and an outer inlet pipe. A first through groove is provided on the side wall of the inner inlet pipe along the length direction, and a second through groove is provided on the side wall of the outer inlet pipe along the length direction. The first through groove and the second through groove are set at an angle, and a float is installed inside the inner inlet pipe.

[0030] The multifunctional water purifier of this invention features a double-layered inlet pipe with grooves on both the inner and outer pipes at an angle. Ozone water is introduced into the multifunctional water purifier through these pipes. A float is placed inside the inner pipe to prevent the ozone water from directly falling into the existing water in the purifier and dissolving rapidly. The design of the inner and outer pipes avoids direct contact and dissolution of the ozone water with the existing water in the purifier. The float and double-layered pipe design slow down the mixing, dissolution, and diffusion rate of the newly prepared ozone water with the existing drinking water in the purifier, thus slowing down the rate of ozone concentration reduction and improving the disinfection and sterilization effect of ozone on the ozone water.

[0031] Furthermore, an inlet pipe sleeve is provided along the axial direction at the edge of the first gasket hole, and the inlet pipe sleeve is located at the bottom of the fixed valve plate mounting groove; the outer inlet pipe is welded to the bottom of the valve plate fixing seat, and the inner inlet pipe is sleeved in the inlet pipe sleeve, with the outer diameter of the inner inlet pipe being greater than or equal to the diameter of the inlet pipe sleeve.

[0032] Furthermore, a second protrusion is provided along the diameter direction at the edge of the first fixed valve hole. The second protrusion prevents the float from floating up and passing through the first fixed valve hole into the transition clean water tank.

[0033] Furthermore, the valve assembly also includes a valve plate cover, which is fixed to the bottom plate of the transition water tank by a mounting rod;

[0034] A first valve stem mounting hole is provided in the middle of the valve plate cover top plate, and the second end of the valve stem passes through the first valve stem mounting hole and is fixed in the valve stem fixing groove;

[0035] The lower part of the valve plate cover top plate is provided with a fixed valve plate pressing part and a movable valve plate pressing part from the outside to the inside. The fixed valve plate pressing part is in contact with the fixed valve plate, and the movable valve plate pressing part and the movable valve plate are spaced apart.

[0036] This invention uses a valve plate cover to fix the moving valve plate and the fixed valve plate. The pressing part of the fixed valve plate presses down on the fixed valve plate to prevent it from moving. The pressing part of the moving valve plate is spaced 1-2mm away from the moving valve plate. When the valve stem or motor is replaced or repaired, the upward movement space of the moving valve plate can be limited to prevent the moving valve plate from moving too much, which facilitates maintenance.

[0037] Furthermore, a first water tank cover is provided on the valve assembly mounting hole of the top plate of the transition water tank; a valve stem mounting channel is provided in the middle of the first water tank cover, a valve stem sealing ring is sleeved on the valve stem mounting channel, and the second end of the valve stem passes through the second valve stem mounting hole at the top of the valve stem sealing ring and the valve stem mounting channel in sequence, extending into the transition water tank and being fixed in the valve stem fixing groove in the middle of the moving valve plate; the diameter of the second valve stem mounting hole is less than or equal to the diameter of the valve stem.

[0038] Furthermore, a valve stem sealing ring fastener is fitted over the valve stem sealing ring, and the valve stem sealing ring fastener fixes the valve stem sealing ring in the valve stem sealing ring mounting groove of the first water tank cover.

[0039] A valve stem sealing ring is used to seal any gaps between the valve stem and the valve stem mounting channel, preventing unsterilized air from entering the water purification tank and contaminating the water. The valve stem sealing ring fastener secures the sealing ring and enhances the seal.

[0040] In some implementations of the present invention, the first water tank cover is fixed to the top plate of the transition clean water tank by bolts, and a first sealing ring is provided between the first water tank cover and the top plate of the transition clean water tank.

[0043] The second water tank cover is fixed to the inner connector of the water tank cover by the second water tank cover connector located at the bottom of the second water tank cover. The inner connector of the water tank cover is welded to the edge of the valve assembly mounting hole on the top plate of the transition clean water tank.

[0044] The first water tank cover is connected to the inside of the second water tank cover via a first water tank cover connector located at the bottom of the first water tank cover.

[0045] A fourth sealing ring is provided between the bottom of the first water tank cover and the top of the second water tank cover, and a third sealing ring is provided between the bottom of the second water tank cover and the inner joint of the water tank cover.

[0046] The top of the second water tank cover is provided with multiple water tank cover fixing seats, which abut against the outside of the first water tank cover.

[0048] The level gauge is sealed and fixed in the valve stem mounting channel in the middle of the first water tank cover, and the level gauge extends through the valve stem mounting channel into the bottom of the multi-functional water purification tank.

Detailed Implementation

[0089] The present invention will be described in detail below with reference to embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other. For ease of description, the words "upper," "lower," "left," and "right" appearing below only indicate that they are consistent with the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0090] Example

[0091] like Figures 1-9This embodiment provides a water purification tank, including a transition water purification tank 11, a multi-functional water purification tank 12, and a valve assembly 1108; the transition water purification tank 11 is located on the upper part of the top plate of the multi-functional water purification tank 12.

[0092] The top plate of the transition water tank 11, the bottom plate of the transition water tank 11, and the top plate of the multi-functional water tank 12 are all provided with valve assembly mounting holes. The valve assembly mounting holes of the bottom plate of the transition water tank 11 and the valve assembly mounting holes of the top plate of the multi-functional water tank 12 overlap. The valve assembly 1108 is perpendicular to the top plate of the transition water tank 11.

[0093] like Figure 17 , Figure 19 The valve assembly 1108 includes a motor 11081, a valve stem 11082, a movable valve plate 11083, and a fixed valve plate 11084. The motor 11081 is located on the upper part of the top plate of the transition water tank 11. The motor 11081 is connected to the first end of the valve stem 11082. The second end of the valve stem 11082 is fixed in the valve stem fixing groove 11083.2 in the middle of the movable valve plate 11083. The fixed valve plate 11084 is located below the movable valve plate 11083 and is disposed in a valve plate fixing seat 1109 welded to the edge of the valve assembly mounting hole on the bottom plate of the transition water tank 11. The valve plate fixing seat 1109 has a cylindrical structure.

[0094] like Figure 20 A moving valve hole 11083.1 is provided on the moving valve plate 11083. For example... Figure 21 The valve plate 11084 has a first valve hole 11084.1 and a second valve hole 11084.2 symmetrically arranged on it.

[0095] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 19 The transition water tank drain pipe 1105 and the multi-functional water tank inlet pipe 1203 are welded to the bottom of the valve plate fixing seat 1109. Two water passage holes are symmetrically arranged at the bottom of the valve plate fixing seat 1109. The two water passage holes at the bottom of the valve plate fixing seat 1109 are respectively connected to the transition water tank drain pipe 1105 and the multi-functional water tank inlet pipe 1203. The multi-functional water tank inlet pipe 1203 extends into the bottom of the multi-functional water tank 12, and the transition water tank drain pipe 1105 extends out of the bottom of the multi-functional water tank 12.

[0096] In some implementations of this embodiment, the bottom of the multifunctional water purification tank 12 is provided with a water trough 1212, and the bottom of the water trough 1212 is lower than the bottom plate of the multifunctional water purification tank 12. The inlet pipe 1203 of the multifunctional water purification tank extends into the bottom of the water trough 1212, and the outlet pipe 1105 of the transition water purification tank extends out of the bottom of the water trough 1212.

[0097] like Figure 17 , Figure 19 The first fixed valve hole 11084.1 is connected to the inlet pipe 1203 of the multi-functional water purifier, and the second fixed valve hole 11084.2 is connected to the drain pipe 1105 of the transition water purifier.

[0098] Motor 11081 drives valve stem 11082 to rotate moving valve plate 11083. When moving valve plate 11083 rotates, moving valve hole 11083.1 connects to first fixed valve hole 11084.1, or connects to second fixed valve hole 11084.2, or is located in other positions on fixed valve plate 11084, not connecting to first fixed valve hole 11084.1 and second fixed valve hole 11084.2.

[0099] This embodiment controls the drainage of the transition water purifier tank and the inflow of water into the multi-functional water purifier tank via a valve assembly. When the ozone concentration is insufficient to meet the sterilization requirements, and the water entering the transition water purifier tank is not adequately sterilized, the moving valve disc is rotated to disconnect the moving valve orifice from the first and second fixed valve orifices. This prevents the transition water purifier tank from draining and the multi-functional water purifier tank from inflowing, thus controlling the residence time of the ozone-contaminated water in the transition water purifier tank. In the transition water purifier tank, the initially purified water undergoes an ozone concentration increase until the water reaches the required ozone sterilization and disinfection effect, thus allowing it to enter the multi-functional water purifier tank. This prevents incompletely sterilized water from mixing with the existing drinking water, thus improving the sterilization and disinfection effect of the water.

[0100] When the water level in the transition water tank exceeds the high water level and the water in the transition water tank still does not meet the water quality requirements, rotate the moving valve plate to connect the moving valve hole to the second fixed valve hole. The water in the transition water tank will be discharged through the transition water tank drain pipe, lowering the water level in the transition water tank and reducing the amount of water in the transition water tank that does not meet the sterilization and disinfection requirements. Ozone-containing water will continue to enter the transition water tank.

[0101] When the water in the transition water tank meets the water quality requirements, rotate the moving valve plate to connect the moving valve hole with the first fixed valve hole. The water in the transition water tank then enters the multi-functional water tank through the multi-functional water tank inlet pipe for subsequent use.

[0102] like Figure 17 , Figure 19 A gasket 11085 is provided between the fixed valve plate 11084 and the valve plate fixing seat 1109, and the fixed valve plate 11084 is disposed within the fixed valve plate mounting groove 11085.4 of the gasket 11085. For example... Figure 22 , Figure 23The gasket 11085 is symmetrically provided with a first gasket hole 11085.1 and a second gasket hole 11085.2. The first gasket hole 11085.1 is connected to the first fixed valve hole 11084.1 and the inlet pipe 1203 of the multi-functional water purifier tank, and the second gasket hole 11085.2 is connected to the second fixed valve hole 11084.2 and the drain pipe 1105 of the transition water purifier tank.

[0103] Gasket 11085 is made of materials such as rubber and silicone.

[0104] The gasket secures the valve plate, preventing it from shifting. It also seals any gaps between the valve assembly and the valve plate holder, preventing incompletely sterilized water from flowing into the multi-functional water purifier tank through these gaps.

[0105] like Figure 22 A first protrusion 11085.3 is provided in the valve plate mounting groove 11085.4, such as... Figure 21 A recess 11084.3 is provided on the fixed valve plate 11084, and a first protrusion 11085.3 engages with the recess 11084.3. This limits the position of the fixed valve plate and prevents it from moving.

[0106] In some implementations of this embodiment, such as Figure 18 , Figure 19 The multi-functional water purifier tank inlet pipe 1203 includes an inner inlet pipe 12031 and an outer inlet pipe 12032. A first through groove 12033 is provided on the side wall of the inner inlet pipe 12031 along the length direction, and a second through groove 12034 is provided on the side wall of the outer inlet pipe 12032 along the length direction. The first through groove 12033 and the second through groove 12034 are set at an angle. A float 1205 is provided inside the inner inlet pipe 12031.

[0107] The inlet pipe of the multi-functional water purifier tank is a double-layered pipe with through-grooves on both the inner and outer pipes, and these grooves are angled. Ozone water is introduced into the multi-functional water purifier tank through these pipes. A float is placed inside the inner pipe to prevent ozone water from falling directly into the existing water in the tank and from dissolving rapidly. The design of the inner and outer pipes avoids direct contact and dissolution of ozone water with the existing water in the tank. The float and double-layered pipe design slow down the mixing, dissolution, and diffusion rate of newly prepared ozone water with the existing drinking water in the tank, thus slowing down the rate at which the ozone concentration in the ozone water decreases and improving the disinfection and sterilization effect of ozone on the ozone water.

[0108] like Figure 19 , Figure 23 , Figure 24An inlet pipe sleeve 11085.5 is provided along the axial direction at the edge of the first gasket hole 11085.1, and the inlet pipe sleeve 11085.5 is located at the bottom of the fixed valve plate mounting groove 11085.4. The outer inlet pipe 12032 is welded to the bottom of the valve plate fixing seat 1109, and the inner inlet pipe 12031 is sleeved in the inlet pipe sleeve 11085.5. The outer diameter of the inner inlet pipe 12031 is greater than or equal to the diameter of the inlet pipe sleeve 11085.5.

[0109] like Figure 21 A second protrusion 11084.4 is provided along the diameter direction on the edge of the first fixed valve hole 11084.1. The second protrusion prevents the float from floating up and passing through the first fixed valve hole into the transition clean water tank.

[0110] In some implementations of this embodiment, such as Figure 17 , Figure 25 , Figure 26 The valve assembly 1108 also includes a valve plate cover 11086, which is fixed to the bottom plate of the transition clean water tank 11 by a mounting rod. A first valve stem mounting hole 11086.2 is provided in the middle of the top plate 11086.1 of the valve plate cover, and the second end of the valve stem 11082 passes through the first valve stem mounting hole 11086.2 and is fixed in the valve stem fixing groove 11083.2. A fixed valve plate pressing part 11086.3 and a movable valve plate pressing part 11086.4 are provided from the outside to the inside of the lower part of the top plate 11086.1 of the valve plate cover. The fixed valve plate pressing part 11086.3 contacts the fixed valve plate 11084 to fix the fixed valve plate 11084. The movable valve plate pressing part 11086.4 and the movable valve plate 11083 are spaced apart.

[0111] In this embodiment, the fixed valve plate is fixed by a valve plate cover, and the fixed valve plate pressing part presses down on the fixed valve plate to prevent it from moving. The moving valve plate pressing part is spaced 1-2mm apart from the moving valve plate. When the valve stem or motor is replaced or repaired, the upward movement space of the moving valve plate can be limited to prevent the moving valve plate from moving too much, which facilitates maintenance.
