Description

Technical Field

[0001] This invention relates to the field of water purification, specifically to a water purification device and method that utilizes secondary water supply via water hammer. Background Technology

[0002] Secondary water supply refers to the process of treating or boosting water from the public water supply system within a city or building, using pumps, storage equipment, and other facilities, before supplying it to users within the building. During secondary water supply, auxiliary equipment is needed to pressurize the water. However, during the liquid flow process, situations such as shut-off can cause a water hammer effect. The water hammer effect is a transient high-pressure phenomenon caused by inertia when a liquid suddenly stops flowing or its flow velocity changes in a pipe. It typically occurs when the fluid flow velocity in a pipe changes drastically, such as when a valve is quickly closed or a pump is suddenly started or stopped, causing a pressure wave to propagate in the pipe and generate an impact force.

[0003] Existing secondary water supply structures typically store water through a storage structure. When water is needed, a water pump pressurizes the water flow and pushes it to a higher position. Then, a disinfection device is used to disinfect the stored water flow, which is then distributed through different pipes.

[0004] However, in existing technologies, although buffer structures such as water hammer absorbers are used to absorb the impact of water hammer when using secondary water supply, these technologies can only absorb the impact of the water flow and cannot collect the water hammer force. Moreover, during the buffering process, the impact is collected by the spring structure, and the large pressure is suddenly eliminated, which can cause equipment damage over time. In addition, existing water hammer elimination equipment also stores water inside, and since there is no disinfection equipment inside the water hammer equipment, bacteria can grow over time. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a water purification device and purification method that utilizes secondary water supply with water hammer, so as to solve the technical problems of the inability to rationally utilize water hammer force and the growth of bacteria inside the water hammer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water purification device utilizing secondary water supply via water hammer, comprising a base, a return weir and a guide pipe installed at the top of the base, an impact valve installed at the top of the return weir, a pressure tank connected to the top of the guide pipe, an inlet pipe installed on the side of the base, a sealing ring and a one-way valve body in an arc shape installed at the connection position between the pressure tank and the guide pipe, a limit component installed at the top of the one-way valve body, an opening provided on the inner wall of the sealing ring, the one-way valve body fitting into the opening, and the bottom end of the one-way valve body being below the sealing ring when fitting, a disinfection ring installed inside the sealing ring, an upper disinfection lamp connected to the top of the disinfection ring inside the pressure tank, a lower disinfection lamp connected to the bottom of the disinfection ring inside the guide pipe, a protective structure installed on the outside of the lower disinfection lamp, a water supply pipe installed on the side of the pressure tank, the output end of the water supply pipe being above the pressure tank, and a high-level water tank installed outside the output end of the water supply pipe.

[0007] By adopting the above technical solution, water can be injected into the base and discharged through the impact valve. When the flow rate reaches a suitable level, the impact valve is closed, and a water hammer is generated in the base. The water hammer enters the pressure tank through the one-way valve and is discharged into the high-level water tank through the water supply pipe. At the same time, the one-way valve closes, allowing the water generated by the water hammer to flow through the water supply pipe, thus preventing pressure loss.

[0008] The present invention is further configured such that an ultraviolet disinfection lamp is installed inside the base below the flow guide tube, a tempered glass is installed at the top of the ultraviolet disinfection lamp, and the outer wall of the ultraviolet disinfection lamp is made of a metal shell.

[0009] Preferably, it allows for convenient disinfection of the base and the interior of the reflux weir.

[0010] The invention is further configured such that a connector is connected to the bottom end of the pressure tank, the connector is fixedly connected to the guide pipe, a gas control valve is connected to the side of the pressure tank, a solenoid valve is installed inside the gas control valve, and the gas control valve is connected to an external gas source.

[0011] Preferably, the pressure inside the pressure tank can be easily controlled by a gas control valve, thereby maintaining a balanced pressure inside the pressure tank.

[0012] The invention is further configured such that a pressure detector is installed at the top of the pressure tank, a guide rod is installed inside the pressure detector, a tray is installed on the outer wall of the guide rod, a pressure spring is connected above the tray, a pressure sensor is installed at the top of the inner wall of the pressure detector, the top of the tray is connected to the force detection end of the pressure sensor, a fixing ring is installed on the outer side of the pressure detector, and the pressure detector is fixedly connected to the pressure tank through the fixing ring. A pressure plate is connected to the bottom end of the guide rod, and a sealing rubber sleeve is fitted on the outer side of the pressure plate.

[0013] Preferably, it facilitates the detection of pressure inside the pressure tank.

[0014] The present invention is further configured such that an electric valve and a one-way check valve are installed inside the water inlet pipe, and the electric valve is electromagnetically controlled, and the one-way check valve controls the water flow to flow unidirectionally into the base.

[0015] Preferably, the valve facilitates the control of the water flow direction within the base, while maintaining the pressure within the base so that it can enter the pressure tank.

[0016] The present invention is further configured such that the limiting component is a fixed frame, the outer wall of the fixed frame is equipped with a connecting rod and a positioning ring, and a limiting ring is connected to the middle position of the fixed frame. A return spring is connected to the bottom end of the limiting ring, and a sliding rod is connected to the top end of the one-way valve body. The sliding rod passes through the limiting ring and is elastically connected to the return spring.

[0017] Preferably, the one-way valve body can be easily limited by the fixing bracket to prevent water pressure inside the pressure tank from returning to the base when the pressure inside the pressure tank increases.

[0018] The invention is further configured such that the protective structure is a transparent protective shell, and the transparent protective shell is sleeved on the outside of each group of lower disinfection lamps, and the outer wall of the lower disinfection lamp is flat.

[0019] Preferably, it allows for convenient protection of the lower disinfection lamp.

[0020] The present invention is further configured such that a filter screen and a limiting ring are installed inside the flow guide tube, the limiting ring is fixed to the inner wall of the flow guide tube, and the filter screen is located above the limiting ring and slidably connected to the flow guide tube, and a side ring is installed on the outer wall of the filter screen.

[0021] Preferably, the water flow can be filtered through a filter screen to reduce impurities entering the pressure tank, and the filter screen is limited by a limiting ring.

[0022] The present invention is further configured such that the top of the filter screen is connected to multiple sets of protective sleeves, the protective sleeves are aligned with the lower disinfection lamp, and a water inlet groove is provided at the position where the protective sleeves fit against the inner wall of the filter screen. When the water flows upward, the water flows through the water inlet groove and enters the protective sleeve. A water outlet groove is provided on the side of the top of the protective sleeve away from the water inlet groove.

[0023] Preferably, when the water flow pushes the filter screen upward, it can protect the lower disinfection lamp through the protective cover, and the water flow can enter the water inlet slot to clean the lower disinfection lamp.

[0024] A water purification method utilizing secondary water supply with water hammer includes the following steps: Step 1: The water inlet pipe supplies water to the inside of the base. The automatic opening and closing of the electric valve generates hydraulic pulses, and the water flows into the base and is discharged through the impact valve. Step 2: When the discharge speed reaches the set value, close the impact valve. At this time, the water flow is cut off, and most of the water flow forms a backflow in the return weir. The one-way check valve is closed to prevent the water flow from flowing back along the inlet pipe, which would increase the water pressure inside the base. The water pressure flows upward along the guide pipe. Under high pressure, the one-way valve body is impacted, pushing the slide rod to move upward. The slide rod moves upward and squeezes the reset spring, causing the one-way valve body to separate from the opening. High-pressure water enters the pressure tank, thereby squeezing and compressing the air in the pressure tank to generate high-pressure gas. The gas pressure is detected by the pressure sensor. Subsequently, some of the high-pressure water will be sent into the high-level water tank through the water supply pipe. Step 3: After the pressure inside the base is released, the pressure inside the pressure tank is greater than the pressure inside the base. At this time, the one-way valve body is no longer subjected to the pressure below. Under the push of gravity and the return spring, the one-way valve body moves downward and fits into the opening, thereby sealing the sealing ring. Step 4: The ultraviolet disinfection lamps can disinfect the water in the base and the return weir, and the disinfection rings can disinfect the guide pipe and the pressure tank.

[0025] In summary, the present invention has the following main beneficial effects: 1. This invention, through its base, pressure tank, and water supply pipe, allows for continuous water injection into the base via the inlet pipe during use. Water is then discharged through an impact valve. When the discharge velocity reaches a certain level, the impact valve closes, causing the flowing water to form a water hammer within the base. This water hammer enters the pressure tank through a guide pipe and pushes a one-way valve upwards, allowing high-pressure water to rush into the pressure tank and discharge into a high-level water tank via the water supply pipe. During this process, when the reaction force of the water hammer returns through the pressure tank, the one-way valve closes, preventing pressure leakage. The reaction force is also injected into the high-level water tank through the water supply pipe, facilitating water lifting.

[0026] 2. The present invention uses a disinfection mechanism to disinfect water in different locations inside the base by activating ultraviolet disinfection lamps and disinfection rings when water flows inside the base, thereby reducing dead corners inside the base.

[0027] 3. The present invention, through the filter screen, can filter the water flow when water hammer enters the pressure tank during use, preventing impurities from entering the pressure tank and causing impurities to accumulate inside, thereby avoiding blockage of the water supply pipe. During the water filling process, the water flow will push the filter screen to move upward synchronously until the filter screen is attached to the bottom of the sealing ring. The protective sleeve is then attached to the outside of the lower disinfection lamp to protect the lower disinfection lamp, thus improving the protection effect. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of the present invention will now be described.

[0032] First embodiment: Please see Figures 1 to 2 A water purification device utilizing secondary water supply via water hammer includes a base 1. A return weir 101 and a guide pipe 102 are installed at the top of the base 1. An impact valve 103 is installed at the top of the return weir 101. An ultraviolet disinfection lamp 104 is installed inside the base 1 below the guide pipe 102. The top of the ultraviolet disinfection lamp 104 is fitted with tempered glass, and the outer wall of the ultraviolet disinfection lamp 104 is made of a metal shell. A pressure tank 2 is connected to the top of the guide pipe 102. An inlet pipe 4 is installed on the side of the base 1. An electric valve 401 and a one-way check valve 402 are installed inside the inlet pipe 4. The electric valve 401 is electromagnetically controlled, and the one-way check valve 402 controls the water flow to flow unidirectionally into the interior of the base 1.

[0033] Please see Figures 1 to 2A sealing ring 7 and a one-way valve body 10 are installed at the connection position between the pressure tank body 2 and the guide pipe 102. The one-way valve body 10 is arc-shaped, and a limit component is installed at the top of the one-way valve body 10. The limit component is a fixing frame 9. A connecting rod 901 and a positioning ring 902 are installed on the outer wall of the fixing frame 9, and a limit ring 903 is connected to the middle position of the fixing frame 9. A return spring 904 is connected to the bottom end of the limit ring 903. A sliding rod 1001 is connected to the top of the one-way valve body 10. The sliding rod 1001 passes through the limit ring 903 and is elastically connected to the return spring 904. The inner wall of the sealing ring 7 has an opening. The one-way valve body 10 fits into the opening 701, and when fitted, the bottom end of the one-way valve body 10 is below the sealing ring 7. A water supply pipe 5 is installed on the side of the pressure tank 2, and the output end of the water supply pipe 5 is located above the pressure tank 2. An elevated water tank 6 is installed outside the output end of the water supply pipe 5. During the water hammer backflow process, the one-way valve body 10 moves upward and opens, and water flows into the pressure tank 2. After the water flows into the pressure tank 2, the one-way valve body 10 is reset and closed under the action of the return spring 904 and the pressure, so that the impact of the water flow can be discharged through the water supply pipe 5.

[0034] Please see Figures 3 to 4 A disinfection ring 8 is installed inside the sealing ring 7. The top of the disinfection ring 8 is located inside the pressure tank 2 and connected to an upper disinfection lamp 801. The bottom of the disinfection ring 8 is located inside the guide pipe 102 and connected to a lower disinfection lamp 802. A protective structure is installed on the outside of the lower disinfection lamp 802. The protective structure is a transparent protective shell 803, which is fitted onto the outside of each set of lower disinfection lamps 802. The outer wall of the lower disinfection lamp 802 is smooth, which can easily disinfect and sterilize the pressure tank 2 and the inside of the base 1, thereby improving the cleanliness of the water.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 5A connector 201 is connected to the bottom of the pressure tank 2, and the connector 201 is fixedly connected to the guide pipe 102. A gas control valve 202 is connected to the side of the pressure tank 2. A solenoid valve is installed inside the gas control valve 202, and the gas control valve 202 is connected to an external gas source. A pressure detector 3 is installed at the top of the pressure tank 2. A guide rod 301 is installed inside the pressure detector 3. A tray 302 is installed on the outer wall of the guide rod 301. A pressure spring 303 is connected to the top of the tray 302. A pressure sensor 304 is installed at the top of the inner wall of the pressure detector 3. The top of the tray 302 is connected to the force detection end of the pressure sensor 304. A fixing ring 305 is installed on the side, and the pressure detector 3 is fixedly connected to the pressure tank 2 through the fixing ring 305. The bottom end of the guide rod 301 is connected to the pressure plate 306, and the outer side of the pressure plate 306 is fitted with a sealing rubber sleeve 307. When the pressure inside the pressure tank 2 increases, the high-pressure gas pushes the guide rod 301 upward through the pressure plate 306, and squeezes the pressure spring 303 through the tray 302. The pressure spring 303 squeezes the pressure sensor 304, and the pressure sensor 304 receives the pressure signal, thereby detecting the pressure inside the pressure tank 2, avoiding excessive or insufficient pressure, and adjusting the gas pressure through the gas control valve 202.

[0036] Second embodiment: Please see Figures 6 to 10This is the second embodiment of the present application. The difference from the first embodiment lies in the protective structure. Specifically, a filter screen 11 and a limiting ring 12 are installed inside the guide pipe 102. The limiting ring 12 is fixed to the inner wall of the guide pipe 102, and the filter screen 11 is located above the limiting ring 12 and slidably connected to the guide pipe 102. A side ring 1101 is installed on the outer wall of the filter screen 11. The side ring 1101 fits against the limiting ring 12, thereby reducing damage to the filter screen 11 during movement. Multiple protective sleeves 1102 are connected to the top of the filter screen 11. The protective sleeves 1102 are aligned with the lower disinfection lamp 802, and a water inlet groove 1103 is provided at the position where the protective sleeve 1102 fits against the inner wall of the filter screen 11. When water flows upward, the water flows through the water inlet groove 1103 and enters the protective sleeve 1102. The top of the protective sleeve 1102 is away from the side of the water inlet groove 1103. The filter screen 1104 is provided with a water outlet groove. When the water flows upward in the guide pipe 102, the water flow drives the filter screen 11 to move upward, pushing the filter screen 11 to fit against the bottom end of the sealing ring 7. At this time, the protective sleeve 1102 is fitted on the outside of the lower disinfection lamp 802 to protect the lower disinfection lamp 802. At this time, the filtered water will enter the protective sleeve 1102 through the water inlet groove 1103 and clean the outside of the lower disinfection lamp 802 through the water flow. The water will be discharged through the water outlet groove 1104. When the one-way valve body 10 is closed, the one-way valve body 10 will quickly return to its original position under the action of water pressure and the return spring 904. At this time, the filter screen 11 has not descended. The bottom end of the one-way valve body 10 passes through the opening 701 and hits the outside of the filter screen 11, vibrating and cleaning the filter screen 11, causing the impurities attached to the filter screen 11 to fall off, thus improving the water permeability of the filter screen 11.

[0037] During use, water is first supplied to the base 1 through the inlet pipe 4. The automatic opening and closing of the electric valve 401 generates hydraulic pulses, allowing water to flow into the base 1. Water is then discharged through the impact valve 103. When the discharge speed reaches the set value, the impact valve 103 is closed, cutting off the water flow. Most of the water flows back into the return weir 101, and the one-way check valve 402 closes to prevent backflow along the inlet pipe 4, thus increasing the water pressure inside the base 1. The water flows upward along the guide pipe 102. Under high pressure, the one-way valve body 10 is impacted, pushing the slide rod 1001 upward. The upward movement of the slide rod 1001 squeezes the return spring 904, causing the one-way valve body 10 to separate from the opening 701. High-pressure water enters the pressure tank 2, compressing the air inside and generating high-pressure gas. The gas pressure is detected by the pressure detector 3. Subsequently, some of the high-pressure water will pass through... Water is fed into the elevated water tank 6 via the water supply pipe 5 (during this process, the generated water hammer pressure is much greater than the self-weight pressure of the water column in the water supply pipe 5, thus driving the water flow within the water supply pipe 5), thereby achieving water transport via water hammer. When the pressure in the base 1 is released, the pressure in the pressure tank 2 is greater than the pressure in the base 1. At this time, the one-way valve body 10 is no longer subjected to the pressure below. Under the push of gravity and the return spring 904, the one-way valve body 10 moves downward and fits against the opening 701, thereby sealing the sealing ring 7, preventing water in the pressure tank 2 from entering the base 1, avoiding water pressure leakage, facilitating the transmission of pressure to the water supply pipe 5, and facilitating water pressure into the elevated water tank 6. Furthermore, the ultraviolet disinfection lamp 104 can disinfect the water in the base 1 and the return weir 101, and the disinfection ring 8 can disinfect the water in the guide pipe 102 and the pressure tank 2, thereby improving the disinfection effect.

The automatic opening and closing of the electric valve generates hydraulic pulses, and the water flows into the base and is discharged through the impact valve. Step 2: When the discharge speed reaches the set value, close the impact valve. At this time, the water flow is cut off, and most of the water flow forms a backflow in the return weir. The one-way check valve is closed to prevent the water flow from flowing back along the inlet pipe, which would increase the water pressure inside the base. The water pressure flows upward along the guide pipe. Under high pressure, the one-way valve body is impacted, pushing the slide rod to move upward. The slide rod moves upward and squeezes the reset spring, causing the one-way valve body to separate from the opening. High-pressure water enters the pressure tank, thereby squeezing and compressing the air in the pressure tank to generate high-pressure gas. The gas pressure is detected by the pressure sensor. Subsequently, some of the high-pressure water will be sent into the high-level water tank through the water supply pipe. Step 3: After the pressure inside the base is released, the pressure inside the pressure tank is greater than the pressure inside the base. At this time, the one-way valve body is no longer subjected to the pressure below. Under the push of gravity and the return spring, the one-way valve body moves downward and fits into the opening, thereby sealing the sealing ring. Step 4: The ultraviolet disinfection lamps can disinfect the water in the base and the return weir, and the disinfection rings can disinfect the guide pipe and the pressure tank.
