Description

Technical Field

[0001] This invention belongs to the field of alkaline electro-ionized water preparation technology, specifically relating to an alkaline electro-ionized water preparation device with multi-stage pretreatment and reverse osmosis functions. Background Technology

[0002] Alkaline ionized water, due to its weak alkalinity and negative potential, is increasingly widely used in daily drinking, medical assistance, and food processing, which has driven the rapid development of alkaline ionized water preparation technology. Currently, alkaline ionized water preparation devices on the market mainly achieve water production through a basic process of "simple filtration + electrolysis". However, in practical applications, many technical shortcomings have gradually been exposed, making it difficult to meet the demand for high-quality and high-efficiency use.

[0003] In the water purification process, existing devices generally suffer from insufficient purification levels. Most devices only employ a single PP cotton filter or activated carbon adsorption structure, which can only remove large particulate impurities and some odors from the raw water. Their removal efficiency for pollutants such as tiny colloids, heavy metal ions (e.g., lead, mercury), dissolved inorganic salts, and microorganisms is extremely poor. These residual pollutants not only lead to low purity of the alkaline ionized water produced by electrolysis, but may also react with the electrodes during electrolysis, generating harmful byproducts that affect water safety. Furthermore, some high-end devices equipped with reverse osmosis membranes lack a proper pretreatment buffer structure, making the reverse osmosis membranes prone to clogging by impurities, shortening the membrane module's lifespan, and increasing equipment maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide an alkaline electro-ionized water preparation device with a simple structure and reasonable design, featuring multi-stage pretreatment and reverse osmosis functions, in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An alkaline electro-ionized water preparation device with multi-stage pretreatment and reverse osmosis functions includes a backwashing component. The backwashing component includes a storage chamber 1. A pretreatment component is fixedly connected to one side of the top of the storage chamber 1.

An electrolytic water production component connected to the interior of the water quality conditioning component is installed on the other side of the top of the storage chamber 1. The pretreatment assembly includes a pretreatment tank fixedly located on one side of the top of storage chamber one. The interior of the pretreatment tank is provided with pretreatment mechanism one, communication mechanism, pretreatment mechanism two and reverse osmosis membrane in sequence from high to low. The concentrate outlet at the bottom of the reverse osmosis membrane is connected to the interior of storage chamber one. The top of the pretreatment tank is covered with a sealing cover, and the top of the sealing cover is fixedly connected to a feeding mechanism.

[0006] As a further optimization of the present invention, a water pump is fixed at the edge of the top side of the storage compartment, the input end of the water pump is fixed with a water outlet pipe connected to the bottom side of the storage compartment, and the output end of the water pump is fixed with a water inlet pipe connected to the inside of the communication mechanism through a pretreatment tank.

[0007] As a further optimization of the present invention, the feeding mechanism includes a water inlet pipe fixedly connected to the top of the sealing cover, a one-way water inlet valve that cooperates with an external water supply pipe is fixedly connected to the top of the water inlet pipe, a branch pipe is fixedly connected to the outside of the water inlet pipe, and a one-way drain valve is fixedly connected to one end of the branch pipe.

[0008] As a further optimization of the present invention, the pretreatment mechanism includes a PP cotton filter plate fixedly located at the top of the pretreatment tank, a stainless steel filter screen plate installed directly below the PP cotton filter plate at the top of the pretreatment tank, and a partition plate fixedly located directly below the stainless steel filter screen plate at the top of the pretreatment tank.

[0009] As a further optimization of the present invention, the connecting mechanism includes a main connecting pipe fixedly connected to the bottom of the inner part of the partition plate one, a one-way water outlet valve fixedly connected to the bottom of the main connecting pipe, a partition plate two fixedly connected to the bottom of the one-way water outlet valve, a branch pipe two fixedly connected to one side of the outside of the main connecting pipe, and a one-way flushing valve that cooperates with the water inlet pipe one fixedly connected to one end of the branch pipe two.

[0010] As a further optimization of the present invention, the pretreatment mechanism two includes an activated carbon filter fixedly located inside the pretreatment tank and placed below the partition plate two. A high-efficiency filter is installed inside the pretreatment tank and placed below the activated carbon filter. A partition plate three is fixed at the bottom of the pretreatment tank, placed below the high-efficiency filter and connected to the top of the reverse osmosis membrane.

[0011] As a further optimization of the present invention, the water quality conditioning component includes a storage tank fixedly located at the top middle position of the storage tank, a water pump two fixedly located at one end of the top of the storage tank, an inlet pipe two fixedly located at the input end of the water pump two that penetrates the bottom of the pretreatment tank and is connected to the freshwater outlet at the bottom of the reverse osmosis membrane, the output end of the water pump two is connected to the inner top of the storage tank, and a water quality detection mechanism fixedly located at the other end of the top of the storage tank.

[0012] As a further optimization of the present invention, the water quality testing mechanism includes a storage tank fixedly located at the rear of the top of the storage chamber, a flow control valve connected to the top of the storage chamber is fixedly located at the bottom of the storage tank, and a water quality sensor extending into the storage chamber is fixedly located at the middle position of the top of the storage chamber, and the water quality sensor is electrically connected to the flow control valve.

[0013] As a further optimization of the present invention, the electrolytic water production assembly includes an electrolytic cell fixedly located on the other side of the top of the storage tank. The electrolytic cell integrates an anode plate, a cathode plate, and an ion exchange membrane. The two sides behind the electrolytic cell are respectively connected to an anode outlet and a cathode outlet. An exhaust pipe is fixedly connected to the top of the electrolytic cell. A water pump three is fixed at the edge of the other side of the top of the storage tank. The input end of the water pump three is connected to the bottom of the storage tank. The output end of the water pump three is fixed with a drain pipe two connected to the inside of the electrolytic cell.

[0014] The beneficial effects of this invention are as follows: 1. This invention employs a five-stage purification system consisting of PP cotton filter plates, stainless steel filter mesh plates, activated carbon filters, high-efficiency filters, and reverse osmosis membranes. The first four pretreatment stages achieve stepwise interception from large particles to microcolloids, while the reverse osmosis membrane further retains inorganic salts, heavy metals, and microorganisms with molecular weights less than 100 Da, reducing the TDS (Total Dissolved Solids) value of the primary purified water to below 50 mg / L, thus laying the foundation for the preparation of high-quality alkaline ionized water.

[0015] 2. This invention utilizes the linkage design of the backwashing component and the pretreatment component, using the concentrated water in the storage chamber as the flushing water source. The backwashing flow channel is formed through the water pump, the inlet pipe, and the one-way flushing valve, which can directly flush the filter components of the pretreatment mechanism. Impurities are discharged through the one-way drain valve. This design eliminates the need to disassemble the components, and the backwashing process can be completed in just 5-10 minutes. This extends the replacement cycle of the filter components from the traditional 1-2 months to 6-8 months, reducing the annual maintenance cost by more than 60%, while avoiding damage to the device's sealing caused by frequent disassembly.

[0016] 3. This invention uses a water quality adjustment component to collect water quality parameters in the storage chamber in real time through a water quality sensor, forming a closed-loop control with the flow control valve. When the pH value deviates from the preset range (e.g., 8.5-9.5), the dosage of the reagent can be automatically adjusted with an adjustment accuracy of ±0.1 pH. This intelligent control method not only avoids errors caused by manual operation, but also automatically adapts the adjustment strategy according to different raw water qualities, ensuring that the pH value of the alkaline ionized water after electrolysis is stable within the target range, and the oxidation-reduction potential (ORP) is maintained between -200mV and -300mV, meeting the usage requirements of different scenarios.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1: As Figure 1 , Figure 2 As shown, the alkaline electro-ionized water preparation device with multi-stage pretreatment and reverse osmosis functions includes four major functional modules: backwashing component 1, pretreatment component 2, water quality conditioning component 3, and electrolytic water production component 4. Each module is sealed and connected through pipelines and connectors to form a complete water production process. The pretreatment component 2 is fixedly connected to one side of the top of the backwashing component 1. The water quality conditioning component 3 is installed in the middle of the top of the backwashing component 1 and is connected to the inside of the pretreatment component 2. The electrolytic water production component 4 is assembled on the other side of the top of the backwashing component 1 and is also connected to the inside of the water quality conditioning component 3. The overall layout is compact and easy to maintain.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, the backwashing assembly 1 serves as the basic support and backwashing power source of the device. Its core is the storage chamber 101, which is made of 304 stainless steel and has good corrosion resistance and pressure resistance. The chamber is used to temporarily store the pre-treated primary purified water. To achieve the backwashing function of the pretreatment assembly 2, a water pump 103 is fixedly installed on the edge of the top side of the storage chamber 101. The input end of the water pump 103 is connected to the outlet pipe 102, and the other end of the outlet pipe 102 extends to the bottom side of the storage chamber 101 and is sealed to it. The output end of the water pump 103 is fixedly connected to the inlet pipe 104. The end of the inlet pipe 104 away from the water pump 103 passes through the shell of the pretreatment assembly 2 and is connected to the internal communication mechanism 204. Through the power output of the water pump 103, the purified water in the storage chamber 101 can be reversed and transported to the pretreatment assembly 2 to achieve the flushing and regeneration of the filter components.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pretreatment component 2 is the key to achieving multi-stage purification of raw water. Its main body is a pretreatment tank 201 fixed to one side of the top of storage compartment 101. The pretreatment tank 201 adopts a cylindrical structure design. A sealing cover is fitted on the top of the pretreatment tank 201, and a silicone sealing gasket is set between the sealing cover and the tank opening to ensure the airtightness during the pretreatment process and prevent sewage leakage. The top of the sealing cover is fixedly connected to the feeding mechanism 202, which serves as the input channel for raw water. The feeding mechanism 202 consists of a water inlet pipe, a one-way water inlet valve 2022, and a one-way drain valve 2021. The system consists of an inlet pipe that vertically penetrates the sealing cover and connects to the interior of the pretreatment tank 201. A one-way inlet valve 2022 is connected to the top of the inlet pipe via a flange. The inlet end of the one-way inlet valve 2022 can cooperate with an external water supply pipe to achieve one-way input of raw water and prevent backflow. A branch pipe is also fixedly connected to the outside of the inlet pipe. A one-way drain valve 2021 is installed at the free end of the branch pipe. The one-way drain valve 2021 is used to discharge sewage and impurities generated during the backwashing process. Its discharge direction is opposite to the raw water inlet direction to ensure thorough discharge.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, inside the pretreatment tank 201, from high to low, there are pretreatment mechanism 1 203, connecting mechanism 204, pretreatment mechanism 205 and reverse osmosis membrane 206, forming a four-stage purification structure. The reverse osmosis membrane 206 is a spiral wound composite reverse osmosis membrane with a molecular weight cutoff of less than 100 Da, which can effectively remove inorganic salts, heavy metal ions and microorganisms from the water. The concentrate outlet at the bottom of the reverse osmosis membrane 206 is connected to the internal sealed connection of storage chamber 101 through a flange, so that the concentrate after reverse osmosis treatment flows directly into storage chamber 101.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pretreatment mechanism 203 is located at the top of the pretreatment tank 201, adjacent to the outlet of the feeding mechanism 202. It consists of a PP cotton filter plate 2031, a stainless steel filter screen 2032, and a partition 2033. The PP cotton filter plate 2031 is fixed at the top of the pretreatment tank 201 and has a pore size of 5μm. It is used to remove large particles of impurities such as silt and rust from the raw water. The stainless steel filter screen 2032 is installed directly below the PP cotton filter plate 2031 and is made of 100-mesh stainless steel mesh. It can further filter suspended impurities in the water and prevent them from clogging subsequent components. The partition 2033 is fixed directly below the stainless steel filter screen 2032 and has a ring structure. It is used to separate the pretreatment mechanism 203 from the communication mechanism 204 below and guide the water flow in a directional manner.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the connecting mechanism 204 is disposed between the first partition 2033 and the second pretreatment mechanism 205. The core includes a connecting main pipe 2041, a one-way flushing valve 2042, a one-way outlet valve 2043, and the second partition 2044. The connecting main pipe 2041 is vertically fixed to the bottom of the first partition 2033, and its top is connected to the chamber below the first partition 2033. The bottom of the connecting main pipe 2041 is fixedly connected to the one-way outlet valve 2043, which only allows water to flow downwards to prevent water in the second pretreatment mechanism 205 from flowing back. The bottom of the one-way outlet valve 2043 is sealed to the partition 2044. The partition 2044 has the same structure as the partition 2033 and is used to support the upper component and separate the connecting mechanism 204 from the pretreatment mechanism 205. A branch pipe 2 is also fixedly connected to one side outside the connecting main pipe 2041. A one-way flushing valve 2042 is installed at the free end of the branch pipe 2. The input end of the one-way flushing valve 2042 is sealed to the inlet pipe 104, allowing only backwash water to flow from the connecting main pipe 2041 to the pretreatment mechanism 203, thus realizing the backwashing function.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pretreatment unit 205 is installed below the partition 2044 and consists of an activated carbon filter 2051, a high-efficiency filter 2052, and a partition 3 2053. The activated carbon filter 2051 is filled with granular coconut shell activated carbon, filling one-third of the volume of the pretreatment tank 201, and is used to adsorb residual chlorine, organic matter, and odors in the water. The high-efficiency filter 2052 is located below the activated carbon filter 2051, and its filter membrane has a pore size of 0.22μm, which can trap colloidal particles and some microorganisms in the water. The partition 3 2053 is fixed to the bottom of the pretreatment tank 201. The part, located below the high-efficiency filter 2052, has a through hole in its center. This through hole is sealed and connected to the inner top of the reverse osmosis membrane 206, allowing the water treated by the pretreatment mechanism 205 to flow directionally into the reverse osmosis membrane 206. Through the structural design of the reverse osmosis membrane 206, the water treated by the pretreatment mechanism 205 can be treated by reverse osmosis. The concentrated water after reverse osmosis flows into the storage chamber 101 for storage, providing a water source for backwashing. The desalinated water after reverse osmosis can enter the water quality conditioning component 3 for storage and water quality parameter regulation.

[0027] like Figure 1 , Figure 2 , Figure 5 As shown, the water quality conditioning component 3 is used to precisely regulate the water quality parameters of the freshwater after reverse osmosis to meet the requirements of subsequent electrolysis. Its main body is the storage tank 301, which is fixed in the middle of the top of the storage tank 101. The storage tank 301 is equipped with a stirring device (not shown in the figure) to ensure uniform water quality conditioning. A water pump 2 302 is fixedly installed at one end of the top of the storage tank 301. The input end of the water pump 2 302 is connected to the water inlet pipe 2 304. The other end of the water inlet pipe 2 304 is sealed and connected to the freshwater outlet at the bottom of the reverse osmosis membrane 206 through the pretreatment tank 201, which can draw the freshwater treated by the pretreatment component 2 into the storage tank 301. The output end of the water pump 2 302 is connected to the inner top of the storage tank 301 to form a stable water conveyance channel.

[0028] like Figure 1 , Figure 2 , Figure 5As shown, a water quality detection mechanism 303 is installed at the other end of the top of the storage tank 301. This mechanism consists of a storage tank 3031, a flow control valve 3032, and a water quality sensor 3033. The storage tank 3031 is fixed at the rear of the top of the storage tank 301 and is used to store water quality conditioning agents such as food-grade sodium hydroxide solution to adjust the pH value of the water. The bottom of the storage tank 3031 is fixedly connected to the flow control valve 3032, and the outlet end of the flow control valve 3032 extends into the storage tank 301. At the middle position of the top of the storage tank 301, a water quality sensor 3033 is fixedly installed. The detection end of the sensor extends through the tank wall into the water inside the storage tank 301 and can detect parameters such as pH value and conductivity in the water in real time. The water quality sensor 3033 and the flow control valve 3032 are electrically connected through a controller. When the water quality parameters are detected to deviate from the preset value, the flow control valve 3032 can automatically adjust the dosage of the agent to achieve precise control of water quality.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the electrolytic water production component 4 is the core unit for generating alkaline ionized water. Its main body is an electrolytic cell 401 fixed on the other side of the top of the storage chamber 101. The electrolytic cell 401 is made of titanium alloy and integrates an anode plate, a cathode plate, and an ion exchange membrane. The anode plate is made of ruthenium-iridium coated titanium plate, the cathode plate is made of pure titanium plate, and the ion exchange membrane is a cation exchange membrane, which can effectively separate hydrogen ions and hydroxide ions generated by electrolysis. An anode outlet 405 and a cathode outlet 406 are respectively set on both sides behind the electrolytic cell 401. The cathode outlet 406 is used to output alkaline ionized water, and the anode outlet 405 is used to discharge acidic water. An exhaust pipe 404 is also fixedly connected to the top of the electrolytic cell 401 to discharge hydrogen, oxygen and other gases generated during electrolysis, ensuring electrolysis safety.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, in order to deliver the adjusted water to the electrolytic cell 401, a water pump 3 402 is fixedly installed on the edge of the other side of the top of the storage chamber 101. The input end of the water pump 3 402 is connected to the bottom of the storage chamber 301 through a pipeline, and the output end of the water pump 3 402 is fixedly connected to the drain pipe 2 403. The other end of the drain pipe 2 403 is sealed and connected to the water inlet of the electrolytic cell 401. Through the stable delivery of the water pump 3 402, the adjusted water continuously enters the electrolytic cell 401 for electrolysis reaction.

[0031] It should be noted that in use, the alkaline electro-ion water preparation device with multi-stage pretreatment and reverse osmosis functions inputs raw water into the pretreatment tank 201 through an external water supply pipe via a one-way inlet valve 2022. The raw water first passes through the PP cotton filter plate 2031 and stainless steel filter screen plate 2032 of the first pretreatment mechanism 203 to remove large particulate impurities and suspended solids. Then, it enters the second pretreatment mechanism 205 through the connecting main pipe 2041 and the one-way outlet valve 2043. After the activated carbon filter 2051 adsorbs odors and residual chlorine, the high-efficiency filter 2052 intercepts colloidal particles. Finally, the water flows through the partition plate 2053 into the reverse osmosis membrane 206 to remove inorganic salts and heavy metal ions, forming primary purified water. The primary purified water can enter the storage chamber 301 for storage through the second water pump 302 and the second inlet pipe 304. The concentrated water produced by the reverse osmosis membrane 206 during operation can flow into the storage chamber 101 for temporary storage through the outlet at the bottom.

[0032] In storage chamber 301, water quality sensor 3033 monitors water parameters in real time. When the pH value is detected to be too low, the controller controls the flow control valve 3032 to open and add conditioning agent into storage chamber 301. The stirring device works synchronously to ensure uniform mixing until the water quality parameters meet the electrolysis requirements.

[0033] Pump 3 402 transports the regulated water in storage tank 301 to electrolytic cell 401 through drain pipe 2 403. When the anode plate and cathode plate in electrolytic cell 401 are energized, an electrolytic reaction occurs. Water molecules generate hydroxide ions and hydrogen gas on the cathode surface. The hydroxide ions remain in the water to form alkaline ionized water, which is discharged and collected through cathode outlet 406. The hydrogen ions generated on the anode surface form acidic water, which is discharged through anode outlet 405. The gas generated by electrolysis is discharged through exhaust pipe 404.

[0034] After the device has been running for a period of time, the water pump 103 is started. The primary purified water in the storage chamber 101 is transported to the one-way flushing valve 2042 of the connecting mechanism 204 through the outlet pipe 102, the water pump 103 and the inlet pipe 104. The water flow reverses to flush the pretreatment mechanism 203. The wastewater generated by flushing is discharged through the one-way drain valve 2021 of the feeding mechanism 202, thus completing the regeneration of the filter components.

[0035] This embodiment integrates multi-stage pretreatment, precise water quality adjustment, electrolytic water production, and backwashing functions through the above structural design, effectively improving the quality and efficiency of alkaline electro-ionized water preparation. The device is stable in operation and easy to maintain, making it suitable for various scenarios such as homes, medical institutions, and food processing.

[0036] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
