This process is relatively slow and the water treatment efficiency is low. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an iron-carbon micro-electrolysis coupled electrochemical water treatment device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an iron-carbon micro-electrolysis coupled electrochemical water treatment device, comprising a reaction tank, the outer wall of which is fixedly connected to a fixed bracket, the top of which is movably connected to a stirring mechanism, and the bottom of which is fixedly connected to a filtering and discharging mechanism; The stirring mechanism includes: A rotating ring, which is movably connected to the top of the reaction tank and is rotatably connected to the reaction tank via a bearing; A stirring motor, wherein the stirring motor is fixedly connected to the top of the rotating ring; The spiral inclined plate is fixedly connected to the inner wall of the spiral inclined plate and is located inside the reaction tank.

[0006] Preferably, an air-guiding stirring rod is fixedly connected to the bottom of the stirring motor, and the air-guiding stirring rod is fixedly connected to the output shaft of the spiral inclined plate. A stirring support rod is fixedly connected to the outer wall of the air-guiding stirring rod. Six stirring support rods are provided, and the bottoms of the three stirring support rods at the bottom are fixedly connected to the bottom stirring plate.

[0007] Preferably, the air-guiding stirring rod is fixedly connected to a compressor motor inside, a spiral air compression plate is fixedly connected to the bottom of the compressor motor, and the spiral air compression plate is fixedly connected to the output shaft of the air-compressing motor, an opening is provided on the outer wall of the air-guiding stirring rod at the top of the spiral air compression plate, and a waterproof cover is fixedly connected to the bottom of the outer wall of the air-guiding stirring rod at the corresponding opening position.

[0008] Preferably, an opening is provided on the outer wall of the stirring support rod, a spring bracket is fixedly connected to the outer wall of the stirring support rod at the corresponding position of the opening, an air blocking plate is movably connected inside the spring bracket, a first spring is fixedly connected to the air blocking plate near one side of the spring bracket, and the spring bracket is fixedly connected.

[0010] Preferably, a barrier sleeve is movably connected inside the filter tube, and a matching closed edge is movably connected inside the barrier sleeve.

[0011] Preferably, a fixing ring is fixedly connected inside the filter drain outlet, a telescopic rod is fixedly connected inside the fixing ring, and the top of the telescopic rod is fixedly connected to the filter tube.

[0012] Preferably, a matching closed edge is fixedly connected to the outer wall of the filter tube near the top, a second spring is fixedly connected to the bottom of the barrier sleeve, and the bottom of the second spring is fixedly connected to the fixing ring.

[0013] The present invention provides an iron-carbon micro-electrolysis coupled electrochemical water treatment device. It has the following beneficial effects: 1. The iron-carbon micro-electrolysis coupled electrochemical water treatment device uses a stirring motor. The stirring motor will drive the air-conducting stirring rod to rotate, the rotating ring will rotate relatively slowly, and the air-conducting stirring rod will rotate relatively quickly. The air-conducting stirring rod will drive the stirring support rod to rotate when rotating, and the stirring support rod will rotate the bottom stirring plate together to stir the water inside the reaction tank. At the same time, the spiral inclined plate will hinder the water at the edge, promote the stirring of the water, and make the iron-carbon micro-electrolysis material powder dispersed more evenly in the water, to speed up the reaction rate, thereby speeding up the wastewater treatment efficiency.

[0014] 2. The iron-carbon micro-electrolysis coupled electrochemical water treatment device drives the spiral air compression plate to rotate through the air compressor motor. The rotation of the spiral air compression plate will press the gas on the top of the spiral air compression plate to the bottom of the spiral air compression plate, so that the air blocking plate compresses the first spring, allowing the gas to enter the water. The continuous rotation of the air-guiding stirring rod allows the gas to come into contact with the water more fully, allowing the oxygen in the air to oxidize the ferrous ions, thereby converting the ferrous ions produced by the reaction in the water into iron ions, thereby producing iron hydroxide colloid for precipitation more quickly, thereby accelerating the treatment efficiency of the wastewater.

[0015] 3. When the iron-carbon micro-electrolysis coupled electrochemical water treatment device produces iron hydroxide colloid, the stirring of the water by the spiral inclined plate and the air-conducting stirring rod can accelerate the contact efficiency between the iron hydroxide colloid and the water, thereby accelerating the iron hydroxide colloid to adsorb impurities in the water for flocculation, thereby accelerating the treatment efficiency of wastewater.

[0016] 4. The iron-carbon micro-electrolysis coupled electrochemical water treatment device extends the telescopic rod to transport the filter tube upward, allowing the water inside the reaction tank to be filtered through the filter tube, leaving impurities inside the reaction tank. The telescopic rod then contracts to move the filter tube downward, pulling the barrier sleeve downward and compressing the second spring, allowing the impurities inside the reaction tank to be discharged through the hole at the top of the filter tube and then discharged from the impurity discharge port, thereby quickly separating the impurities and water that have accumulated inside the reaction tank, and actually accelerating the water treatment speed.

[0017] 5. In the iron-carbon micro-electrolysis coupled electrochemical water treatment device, when the filter tube is filtering, the air-guiding stirring rod rotates continuously, which will drive the bottom stirring plate to rotate, and the water around the filter tube will be driven to rotate. Impurities will be moved away from the filter tube under the action of centrifugal force, avoiding the accumulation of impurities on the surface of the filter tube and causing filtration blockage, which can indirectly speed up the treatment of wastewater.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: an iron-carbon micro-electrolysis coupled electrochemical water treatment device, comprising a reaction tank 1, a fixed bracket 2 is fixedly connected to the outer wall of the reaction tank 1, a stirring mechanism 3 is movably connected to the top of the reaction tank 1, and a filtering and discharging mechanism 4 is fixedly connected to the bottom of the reaction tank 1; The stirring mechanism 3 comprises: A rotating ring 301, which is movably connected to the top of the reaction tank 1, and the rotating ring 301 is rotatably connected to the reaction tank 1 through a bearing; A stirring motor 302, the stirring motor 302 is fixedly connected to the top of the rotating ring 301; The spiral inclined plate 303 is fixedly connected to the inner wall of the spiral inclined plate 303 and is located inside the reaction tank 1 .

[0023] An air-guiding stirring rod 304 is fixedly connected to the bottom of the stirring motor 302, and the air-guiding stirring rod 304 is fixedly connected to the output shaft of the spiral inclined plate 303. A stirring support rod 305 is fixedly connected to the outer wall of the air-guiding stirring rod 304. Six stirring support rods 305 are provided, and the bottoms of the three stirring support rods 305 located at the bottom are fixedly connected to the bottom stirring plate 306. The stirring motor 302 will drive the air-guiding stirring rod 304 to rotate. According to the momentum theorem, it will also drive the rotating ring 301 to rotate. The rotation of the rotating ring 301 will cause the spiral inclined plate 303 on the inner wall of the rotating ring 301 to rotate, which plays a role in pushing the water opened into the inner wall of the reaction tank 1 to the bottom. However, because the resistance of the spiral inclined plate 303 is large, the rotating ring 301 will rotate relatively slowly, and the air-guiding stirring rod 304 will rotate relatively quickly.

[0024] The air-guiding stirring rod 304 is fixedly connected with an air compressor motor 307 inside, and a spiral air compressor plate 308 is fixedly connected with the bottom of the air compressor motor 307, and the spiral air compressor plate 308 is fixedly connected to the output shaft of the air compressor motor 307. An opening is arranged on the outer wall of the air-guiding stirring rod 304 at the top of the spiral air compressor plate 308, and a waterproof cover 309 is fixedly connected to the bottom of the outer wall of the air-guiding stirring rod 304 at the corresponding opening position, and the waterproof cover 309 can prevent water from accidentally entering the air-guiding stirring rod 304 and affecting the smooth flow of air. The air compressor motor 307 will drive the spiral air compressor plate 308 to rotate, and the rotation of the spiral air compressor plate 308 will press the gas at the top of the spiral air compressor plate 308 to the bottom of the spiral air compressor plate 308, which allows the gas to enter from the opening of the air-guiding stirring rod 304. Due to the increase in air pressure at the bottom of the spiral air compressor plate 308, the gas will push open the air blocking plate 311, so that the air blocking plate 311 compresses the first spring 312, allowing the gas to enter the water.

[0025] An opening is provided on the outer wall of the stirring support rod 305, and a spring bracket 310 is fixedly connected to the outer wall of the stirring support rod 305 at the corresponding position of the opening. An air blocking piece 311 is movably connected inside the spring bracket 310, and a first spring 312 is fixedly connected to the air blocking piece 311 near the side of the spring bracket 310, and 32 is fixedly connected to the spring bracket 310.

[0026] When in use, wastewater is injected into the reaction tank 1, and the iron-carbon micro-electrolysis material is filled into the reaction tank 1 to react with the wastewater. At this time, the stirring motor 302 is started, and the stirring motor 302 will drive the gas-guiding stirring rod 304 to rotate. According to the momentum theorem, it will also drive the rotating ring 301 to rotate. The rotation of the rotating ring 301 will cause the spiral inclined plate 303 on the inner wall of the rotating ring 301 to rotate, which plays a role in pushing the water entering the inner wall of the reaction tank 1 to the bottom. However, because the resistance of the spiral inclined plate 303 is large, the rotating ring 301 will rotate relatively slowly, and the gas-guiding stirring rod 304 will rotate relatively quickly. When the gas-guiding stirring rod 304 rotates, it will drive the stirring support rod 305 to rotate, and the stirring support rod 305 will rotate together with the bottom stirring plate 306 at the bottom to stir the water inside the reaction tank 1. At the same time, the spiral inclined plate 303 will hinder the water at the edge, promote the stirring of the water, so that the iron-carbon micro-electrolysis material is more evenly dispersed in the water, so as to accelerate the reaction rate.

[0027] At the same time, when the air-guiding stirring rod 304 is driven to stir the water inside the reaction tank 1, the air compressor motor 307 is started synchronously, and the air compressor motor 307 will drive the spiral air compression plate 308 to rotate. The rotation of the spiral air compression plate 308 will press the gas at the top of the spiral air compression plate 308 to the bottom of the spiral air compression plate 308, which allows the gas to enter from the opening of the air-guiding stirring rod 304. Due to the increase in air pressure at the bottom of the spiral air compression plate 308, the gas will push open the air blocking plate 311, allowing the air blocking plate 311 to compress the first spring 312, allowing the gas to enter the water, and through the continuous rotation of the air-guiding stirring rod 304, the gas can be more fully in contact with the water, allowing the oxygen in the air to oxidize the ferrous ions, thereby converting the ferrous ions produced by the reaction in the water into iron ions, thereby producing iron hydroxide colloid more quickly for precipitation.

[0028] When the iron hydroxide colloid is generated, the stirring of the water by the spiral inclined plate 303 and the air-guiding stirring rod 304 can accelerate the contact efficiency between the iron hydroxide colloid and the water, thereby accelerating the iron hydroxide colloid to adsorb impurities in the water for flocculation.

[0029] Example 2: Please refer to Figure 1-10 Based on the first embodiment, the present invention provides a technical solution: The filter discharge mechanism 4 comprises a debris discharge port 401 , which is fixedly connected to the bottom of the reaction tank 1 , and a filter drain port 402 is fixedly connected to the bottom of the debris discharge port 401 .

[0030] The filter tube 403 is movably connected inside with a barrier sleeve 407, and the barrier sleeve 407 is movably connected inside with a matching closed edge 408. The telescopic rod 404 is extended to transport the filter tube 403 upward, so that the water inside the reaction tank 1 can be filtered through the filter tube 403, and the clean water can flow into the filter drain outlet 402 through the filter tube 403 and be discharged.

[0031] A fixing ring 405 is fixedly connected inside the filter drain outlet 402 , a telescopic rod 404 is fixedly connected inside the fixing ring 405 , and the top of the telescopic rod 404 is fixedly connected to the filter tube 403 .

[0032] The outer wall of the filter tube 403 is fixedly connected with a matching closed edge 408 near the top, and the bottom of the barrier sleeve 407 is fixedly connected with a second spring 406. The bottom of the second spring 406 is fixedly connected to the fixed ring 405. The telescopic rod 404 contracts to allow the filter tube 403 to move downward, and the matching closed edge 408 is used to fit the barrier sleeve 407 to pull the barrier sleeve 407 downward and compress the second spring 406, so that the impurities inside the reaction tank 1 can be discharged through the hole at the top of the filter tube 403, and then discharged from the impurity discharge port 401.

[0033] During use, when the iron hydroxide in the reaction tank 1 gathers into impurities, the telescopic rod 404 is extended to transport the filter tube 403 upward, so that the water inside the reaction tank 1 is filtered through the filter tube 403, and the clean water flows into the filter drain port 402 through the filter tube 403 and is discharged, and the impurities will remain in the reaction tank 1. Then the telescopic rod 404 contracts to move the filter tube 403 downward, and through the cooperation of the closed edge 408 to fit with the barrier sleeve 407, the barrier sleeve 407 is pulled downward, and the second spring 406 is compressed, so that the impurities inside the reaction tank 1 can be discharged through the hole at the top of the filter tube 403, and then discharged from the impurity discharge port 401, so as to quickly separate the impurities and water gathered inside the reaction tank 1.

[0034] When the filter tube 403 is filtering, the air-guiding stirring rod 304 rotates continuously, and the stirring support rod 305 drives the bottom stirring plate 306 to rotate, which drives the water around the filter tube 403 to rotate. This allows the impurities to move away from the filter tube 403 under the action of centrifugal force, avoiding the accumulation of impurities on the surface of the filter tube 403 and causing filtration blockage.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
