Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to an intelligent water purification device. Background Technology

[0002] Electrolysis of wastewater can remove impurities and toxic substances. For example, processes like electroplating produce wastewater containing heavy metals, including large amounts of hexavalent chromium ions. Currently, electrolysis is primarily used to convert hexavalent chromium ions into trivalent chromium ions, which then flocculate and precipitate in the liquid, thus separating them from the wastewater.

[0003] Electrolysis devices typically involve immersing several energized electrode plates in wastewater, causing the wastewater to flow through them and be electrolyzed. In actual use, the quality and flow rate of the wastewater frequently change, while the specifications of the electrolysis device are usually fixed. For example, when the amount of heavy metal ions to be electrolyzed in the wastewater is large, a strong electric field is required between the electrode plates, and the flow rate between the electrode plates is small. That is, under a constant voltage, the spacing between the electrode plates needs to be small, and vice versa. However, the existing fixed-spacing electrode plates cannot be adjusted, which cannot meet the needs of changing operating conditions and affects the wastewater purification efficiency. Summary of the Invention

[0004] To address the problem that existing electrolysis devices cannot flexibly adjust according to changes in operating conditions, this invention proposes an intelligent water purification device that can flexibly adjust the spacing of the electrode plates according to changes in operating conditions, thereby improving the efficiency of electrolytic water purification.

[0005] The technical solution adopted in this invention is to design an intelligent water purification device, including a pre-reaction tank and a post-reaction tank, which are connected by a water inlet. The pre-reaction tank is connected to an inlet pipe, and the post-reaction tank is connected to a drain pipe. Wastewater enters through the inlet pipe and exits through the drain pipe. The device also includes sensors for monitoring the concentration of heavy metal ions in the pre-reaction tank or the flow rate of the inlet pipe. The water inlet is equipped with a wastewater electrolysis device, which includes several electrode plates arranged at intervals on the flow cross section of the water inlet. The electrode plates are respectively connected to the hinge shaft of a scissor lift frame, and the spacing between the electrode plates is controlled by the extension and retraction of the scissor lift frame.

[0006] In some embodiments, the water inlet is provided with a telescopic gate, which includes a telescopic plate that extends and retracts relative to the edge of the water inlet. The telescopic plate is connected to the electrode plate at the end, so that the telescopic plate moves relative to the edge of the water inlet as the scissor lift telescopic frame extends and retracts, thereby adjusting the size of the water inlet.

[0007] In some embodiments, the rim of the water inlet is provided with a telescopic cavity that slides with the telescopic plate.

[0008] In some embodiments, the pre-reaction tank is equipped with a dosing device for adding auxiliary electrolytic flocculants into the tank; the post-reaction tank is equipped with a sedimentation device for preventing accidental precipitation due to electrolytic flocculation.

[0009] In some embodiments, one of the two opposing end hinge shafts of the scissor lift is rotatably connected to the electrode plate, and the other end hinge shaft is connected to the inverted U-shaped frame. The electrode plate is located between the left and right frames of the inverted U-shaped frame, and scrapers that contact the surface of the electrode plate are provided on the left and right frames.

[0010] In some embodiments, an aeration pipe is connected to the central hinge shaft of the scissor lift, the aeration pipe is provided with an air outlet, and the aeration pipe is connected to an air supply pipeline.

[0011] In some embodiments, a stirring column with helical blades is connected to the central hinge shaft of the scissor lift, and a motor for controlling the rotation of the stirring column is connected above the central hinge shaft.

[0012] In some embodiments, the motor slides on a transverse slide rail, and sliders are connected to both ends of the transverse slide rail, with the sliders sliding on a longitudinal slide rail.

[0013] In some embodiments, a light-emitting element is connected to the central hinge axis of the scissor lift.

[0014] In some embodiments, an ultrasonic generator is connected to the central hinge shaft of the scissor lift.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention allows for the synchronous adjustment of the spacing between all electrode plates. The arranged electrode plates are used not only for electrolysis but also for controlling the flow rate of wastewater. This allows for control of the electric field strength according to the characteristics of the wastewater, ensuring thorough electrolysis. The flow rate can also be controlled as needed for rapid wastewater treatment. An electrode plate cleaning device is included, which can scrape off deposits on the electrode plate surface while fixing the plates. An agitation device for the wastewater is installed between the electrode plates, ensuring thorough mixing, preventing laminar flow, and ensuring full contact between the wastewater and the substrate. This results in uniform contamination throughout the wastewater, protecting the electrodes and improving electrolysis efficiency. Attached Figure Description

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.

[0024] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1 , 2As shown, an intelligent water purification device includes a pre-reaction tank and a post-reaction tank, which are connected by a water inlet. The pre-reaction tank is connected to an inlet pipe 2, and the post-reaction tank is connected to a drain pipe 4. Wastewater enters through the inlet pipe 2 and exits through the drain pipe 4. The device also includes a sensor 21 for monitoring the concentration of heavy metal ions in the pre-reaction tank or the flow rate of the inlet pipe 2. A wastewater electrolysis device is installed at the water inlet, comprising several electrode plates 5 spaced apart on the flow cross-section of the water inlet. The electrode plates 5 are respectively connected to the hinge shafts of a scissor lift frame 6. The spacing between the electrode plates 5 is controlled by the extension and retraction of the scissor lift frame 6, thereby adjusting according to the water quality or flow rate of the wastewater to adapt to operating conditions and achieve better water purification efficiency. Wastewater enters the post-reaction tank from the pre-reaction tank and flows through the electrode plates 5, where it is electrolyzed to remove heavy metal ions, causing the heavy metal ions to flocculate and separate from the wastewater. The spacing of all electrode plates 5 is adjusted synchronously. These arranged electrode plates are used not only for electrolysis but also for controlling the flow rate of wastewater. This allows for control of the electric field size based on the characteristics of the wastewater, ensuring thorough electrolysis. The flow rate can also be controlled as needed for rapid wastewater treatment. The sensor 21 for detecting heavy metal ion concentration can be, for example, a conductivity sensor 21. By measuring changes in the conductivity of the solution, the concentration of metal ions can be inferred, making it particularly suitable for measuring high concentrations of metal ions.

[0027] The pre-reaction tank is equipped with a dosing device for adding auxiliary electrolytic flocculants, such as a flow pump 22. The post-reaction tank is equipped with a sedimentation device to aid in the precipitation of electrolytic flocculation. The pre-reaction chamber 1 can serve as a dosing chamber, into which auxiliary agents to enhance flocculation or electrolysis can be added, such as iron-carbon particles, to assist in electrolytic flocculation. The post-reaction chamber 3 serves as a sedimentation tank for the flocculants after electrolysis. The sedimentation device can be, for example, a baffle plate 23 installed in the post-reaction tank, which allows the flocculants to settle under the baffle plate 23's deflection action.

[0028] The scissor lift telescopic frame 6 includes a connecting rod for scissor lifts. The middle part of the connecting rod is rotatably connected by a central hinge shaft 12, and the two ends of the connecting rod are rotatably connected by end hinge shafts 7, so that each part of the scissor lift telescopic frame 6 can extend and retract synchronously. The principle is the same as that of the scissor lift mechanism of the scissor lift platform.

[0029] The water inlet is equipped with a telescopic gate, which includes a telescopic plate 10 that extends and retracts relative to the edge of the water inlet. The telescopic plate 10 is connected to the electrode plate 5 at the end. The edge of the water inlet is provided with a telescopic cavity 11 that slides and engages with the telescopic plate 10. The telescopic plate 10 can extend and retract relative to the telescopic cavity 11. The telescopic cavity 11 and the telescopic plate 10 isolate the liquid in the front reaction chamber 1 and the rear reaction chamber 3. The telescopic plate 10 moves relative to the edge of the water inlet as the scissor lift frame 6 extends and retracts, thereby adjusting the size of the water inlet. This allows the change in the size of the water inlet to adapt to the change in the spacing of the electrode plates 5, and also allows for the adjustment of the flow rate of the water inlet.

[0030] The electrode plate 5 at the other end of the scissor lift telescopic frame 6 is fixedly connected to the other edge of the water inlet. A telescopic control device, such as a pneumatic cylinder or hydraulic cylinder, can be connected between the telescopic plate 10 and the telescopic cavity 11. This telescopic control device can be housed within the telescopic cavity 11 to control the extension or retraction of the telescopic plate 10 relative to the cavity. The telescopic control device's extension and retraction are controlled based on the monitored heavy metal ion concentration or the flow rate information from the inlet pipe 2.

[0031] One of the two opposing end hinge shafts 7 of the scissor lift frame 6 is rotatably connected to the electrode plate 5, and the other end hinge shaft 7 is connected to the inverted U-shaped frame 8. The electrode plate 5 is located between the left and right frames of the inverted U-shaped frame 8, and scrapers 9 are provided on the left and right frames to contact the surface of the electrode plate 5. While fixing the electrode plate 5, scrapers 9 can also be used to remove deposits from the surface of the electrode plate 5. When the scissor lift frame 6 extends and deforms, the inverted U-shaped frame 8 moves relative to the electrode plate 5, thereby allowing the scrapers 9 to remove deposits from their surface, preventing passivation of the electrode plate 5, ensuring the cleanliness of the electrode plate 5 surface, and maintaining electrolysis efficiency.

[0032] The telescopic plate 10 can extend and retract relative to the telescopic cavity 11, causing the spacing between the electrode plates 5 to change. For example, when the telescopic plate 10 extends, the spacing between the electrode plates 5 will become smaller, thereby reducing the water flow between the electrode plates 5, strengthening the electric field between the electrode plates 5, and increasing the density of the aerated gas, which is beneficial for the electrolytic flocculation of high concentrations of heavy metal ions.

[0033] When the telescopic plate 10 retracts, the spacing between the electrode plates 5 increases, which facilitates the rapid passage of sewage and improves the sewage purification speed. If the concentration of heavy metal ions in the sewage is also high, the voltage between the electrode plates 5 can be increased at the same time, which increases the sewage flow rate and the electrolysis efficiency. This is suitable for situations where a large amount of sewage needs to be treated in a short time. However, the electrode plates 5 cannot work under high voltage for a long time to avoid accelerated corrosion or passivation of the electrode plates 5.

[0034] An aeration pipe 13 is connected to the central hinge shaft 12 of the scissor lift telescopic frame 6. The aeration pipe 13 is provided with an air outlet and is connected to the air supply pipe 14, so that gas enters between the two electrode plates 5 through the aeration pipe 13, thereby aerating the sewage while electrolyzing it, improving the electrolytic flocculation efficiency. The gas also helps the flocs to float, allowing them to quickly enter the sedimentation tank.

[0035] Because the distance between the electrode plates 5 is small and the area of ​​the electrode plates 5 is large, the solution forms a laminar flow when the liquid flows naturally between the electrode plates 5. This is not conducive to the full mixing of the liquid to form flocs, nor is it conducive to the uniformity of the liquid composition. The uneven composition of the liquid in different places can easily lead to different electrolysis effects in different parts of the substrate, resulting in uneven corrosion of the substrate, affecting the service life of the electrode plates 5 and the electrolysis effect. Stable laminar flow is also not conducive to the full contact between the liquid and the electrode plates 5. Gas is introduced between the electrode plates 5 for aeration in order to accelerate the flocculation or chemical transformation of the pollutants.

[0036] Example 2

[0037] like Figure 3 , 4 As shown, unlike the previous embodiment, a stirring column 15 is connected to the central hinge shaft 12 of the scissor lift frame 6. The stirring column 15 has spiral blades, and a motor 16 controlling the rotation of the stirring column 15 is connected above the central hinge shaft 12. The motor 16 is slidably engaged with a transverse slide rail 17, and sliders 18 are connected to both ends of the transverse slide rail 17. The sliders 18 are slidably engaged with a longitudinal slide rail 19, which is fixed relative to the reaction tank. The motor 16 drives the stirring column 15 to rotate, and the spiral blades agitate the wastewater, causing the wastewater at the bottom to move upwards, ensuring thorough electrolysis of the wastewater and allowing the pollutants to undergo a complete chemical reaction, regardless of changes in the electrode plate spacing 5. The stirring column 15 ensures thorough mixing of the wastewater, preventing laminar flow, ensuring full contact between the wastewater and the substrate, uniform distribution of pollutants throughout the wastewater, protecting the electrodes, and improving electrolysis efficiency.

[0038] Alternatively, a light source can be connected to the central hinge shaft 12 of the scissor telescopic frame 6 between the electrode plates 5 to perform photocatalysis on the pollutants during electrolysis; an ultrasonic generator can also be connected to the central hinge shaft 12 of the scissor telescopic frame 6 between the electrode plates 5 to cause the sewage to vibrate, accelerate the electrolysis reaction, and suppress electrode polarization or passivation.

[0039] Because the central hinge shaft 12 moves synchronously when the scissor telescopic frame 6 deforms, it can ensure that the light source, ultrasonic wave, aeration device, and stirring column 15 are always located in the middle between two adjacent electrode plates 5, thus ensuring uniform effect.

Those skilled in the art can make various modifications or additions to the described embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
