Description

Technical Field

[0001] The invention relates to the technical field of river water filtration, in particular to a river water pollution removal and filtration device based on the generation of hydroxyl free radicals. Background Art

[0002] With the continuous development of living standards and industrial production, more and more garbage and sewage are continuously discharged into rivers, causing river water to be polluted and rivers to become gathering places for sewage. In order to protect the environment, relevant units need to purify the sewage in the river so that the sewage can be purified for reuse. Filtration is an important process for sewage purification, so special filtration devices are needed in the process of purifying river sewage.

[0003] Hydroxyl free radicals are a type of active oxygen with an extremely high oxidation potential, and their oxidation capacity is second only to fluorine. In the process of water electrolysis, a large number of hydroxyl free radicals can be rapidly electrolyzed through the action of the anode and cathode. These hydroxyl free radicals react quickly with organic pollutants in river water in a chain reaction, oxidizing them into carbon dioxide, water or mineral salts, thereby achieving the purpose of purifying water quality.

[0004] Its main function is to rely on the strong oxidizing property of hydroxyl free radicals to degrade organic pollutants, inorganic pollutants and microorganisms in river water, thereby achieving the purpose of purifying water quality. However, for floating objects in river water, such as leaves, plastic waste, plankton, etc., the device may not have a direct filtering and intercepting effect. It simply filters the solid waste in the sewage. When the solid waste is large and there are many of them, it is easy to cause blockage in the filtering device, causing the sewage filtration to stagnate. The filtration work must be suspended for replacement, and the filtration efficiency is low, resulting in insufficient purification effect of polluted river water. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1-7 , the present invention provides the following technical solution: The river water decontamination and filtering device based on the generation of hydroxyl free radicals includes a rotating drum 1, a rotating shaft 2 is rotatably connected to the interior of the rotating drum 1, and a wheel 11 is fixedly connected to the outer wall of the rotating shaft 2, a transmission drum 4 is fixedly connected to the bottom of the rotating drum 1, and a filter screen 5 is fixedly installed on the inner wall of the transmission drum 4.

[0021] A filtering mechanism 3 is provided at the end of the rotating shaft 2 .

[0022] Furthermore, the filtering mechanism 3 includes a movable frame 301, and the inner wall of the movable frame 301 is provided with a tooth groove 302, the side wall of the movable frame 301 is penetrated with a second slide groove 303, and the inner wall of the second slide groove 303 is slidably connected with a connecting shaft 304, the outer wall of the connecting shaft 304 is fixedly connected with a half-circle tooth 305, and the inner wall of the half-circle tooth 305 is matched and meshed with the inner wall of the tooth groove 302, and both ends of the movable frame 301 are fixedly connected with a first connecting rod 306, and the first connecting rod 306 is fixedly connected with the inner wall of the tooth groove 302. A fixed rod 307 is fixedly connected to the bottom, a second connecting rod 308 is fixedly connected to the bottom of the fixed rod 307, a sliding rod 309 is fixedly connected to the side wall of the second connecting rod 308, and a fixed plate 310 is fixedly connected to the outer wall of the sliding rod 309. The top of the rotating drum 1 is fixedly connected to the water inlet 12, and the interior of the water inlet 12 is connected to the interior of the rotating drum 1. A hydroxyl radical filter 13 is fixedly installed at the bottom of the transmission drum 4, and a drain outlet 14 is fixedly connected to the side wall of the hydroxyl radical filter 13.

[0023] In this embodiment, the hydroxyl radical filter 13 relies on the strong oxidizing ability of the hydroxyl radicals at its core to degrade the organic pollutants, inorganic pollutants and microorganisms in the river water, so as to achieve the goal of purifying the water quality. First, the river water is diverted to the water inlet 12, and then it can flow into the interior of the drum 1 from the water inlet 12. Thereafter, the river water flows along the inner wall of the drum 1, and then when it flows to the bottom of the drum 1, it will flow into the interior of the transmission drum 4, and then it will contact the filter screen 5 during the downward flow, so that the river water is filtered by the filter screen 5, so that the solid waste in the river water is filtered and remains on the surface of the filter screen 5, thereby completing the preliminary filtration of the river water and preventing the solid waste in the river water from affecting the subsequent filtration. Then, the filtered river water will continue to flow downward, and then enter the interior of the hydroxyl radical filter 13, and the river water will be further filtered by the strong oxidizing ability of the hydroxyl radicals, and then discharged through the drain outlet 14.

[0024] After filtering a large amount of river water, a large amount of solid waste may clog the filter 5, causing the river water to be blocked during the treatment process, or even stagnant in the flow of the river water, thereby significantly reducing the filtering efficiency. By cleaning the solid waste on the surface of the filter 5 while filtering the river water, the filter 5 can be prevented from being blocked. Since the water inlet 12 is located on one side of the drum 1, it will only flow in half of the space inside the drum 1. When the river water enters the drum 1, the water flow will impact the impeller 11, and then the impeller 11 After being impacted, the rotating shaft 2 will be driven to rotate, and the end of the connecting shaft 304 close to the tooth groove 302 is fixedly connected to the end of the rotating shaft 2, so that the rotating shaft 2 will drive the connecting shaft 304 to rotate, so that the connecting shaft 304 drives the half-circle gear 305 to rotate synchronously. Since the gear teeth of the half-circle gear 305 match and mesh with the tooth groove 302 above, when the half-circle gear 305 rotates, the movable frame 301 will drive the fixed rod 307 to move synchronously through the first connecting rod 306, and at the same time, the outer wall of the connecting shaft 304 will slide in contact with the inner wall of the second sliding groove 303, so that the movable frame 30 1 keeps translation, and then when the half-circle gear 305 rotates the second half circle, the gear teeth of the half-circle gear 305 will match and mesh with the tooth grooves 302 below. Then, when the half-circle gear 305 continues to rotate, the movable frame 301 drives the fixed rod 307 through the first connecting rod 306 to translate in the opposite direction at the same time, so that the movable frame 301 will reciprocate when the half-circle gear 305 rotates one circle. When the movable frame 301 drives the second connecting rod 308 to reciprocate through the fixed rod 307, the sliding rod 309 penetrates and slides in the interior of the transmission cylinder 4, so that The sliding rod 309 drives the fixed plate 310 to move back and forth inside the transmission cylinder 4. The bottom of the fixed plate 310 is fixedly connected with a cleaning block 7, and the bottom of the cleaning block 7 slides in contact with the top of the filter screen 5. At the same time, the fixed plate 310 drives the cleaning block 7 to slide back and forth along the upper surface of the filter screen 5. During the sliding process of the cleaning block 7, the solid waste on the surface of the filter screen 5 will be scraped and pushed, thereby ensuring that the filter screen 5 can be cleaned at the same time during the filtering of the river water, avoiding a large amount of solid waste from staying on the surface of the filter screen 5 and clogging the filter screen 5.

[0025] As described above, when filtering river water, the water flow impacts the impeller 11 to drive the rotating shaft 2 to rotate, so that the connecting shaft 304 drives the half-circle gear 305 to rotate synchronously, and by setting the filter screen 5, the movable frame 301 is made to perform reciprocating translational motion, and the sliding rod 309 drives the cleaning block 7 to slide through the fixed plate 310, thereby scraping and pushing the solid garbage on the surface of the filter screen 5, thereby ensuring that in the process of filtering the river water, a large amount of solid garbage is prevented from staying on the surface of the filter screen 5 and clogging the filter screen 5, and the river water can be continuously and effectively filtered to ensure the continuity and stability of the filtering process. The impact force of the water flow itself is used as the power source, and no additional electricity or mechanical energy input is required, thereby reducing operating costs and environmental impacts.

[0026] Embodiment 2: Based on the above embodiment, a collecting mechanism 6 is provided on the outer wall of the transmission cylinder 4 .

[0027] Furthermore, the collecting mechanism 6 includes a collecting box 601, and a collecting chamber 602 is provided inside the collecting box 601, the inner wall of the collecting chamber 602 is slidably connected with a pressure plate 603, and the top of the pressure plate 603 is fixedly connected with a spring 604, the end of the spring 604 away from the pressure plate 603 is fixedly connected to the top of the inner wall of the collecting chamber 602, an inclined groove 605 is provided at the bottom of the pressure plate 603, and the inner wall of the inclined groove 605 is slidably connected with a stop block 606, and a slot 607 is provided on the side wall of the stop block 606, a filter hole 608 is fixedly installed at the bottom of the collecting chamber 602, and a conveying pipe 609 is fixedly connected to the bottom of the filter hole 608, and a one-way valve 610 is fixedly installed at the end of the conveying pipe 609 away from the filter hole 608, the outer wall of the cleaning block 7 slides in contact with the inner wall of the discharge trough 9, the interior of the transmission cylinder 4 is connected to the collecting chamber 602, and the bottom of the stop block 606 is slidably connected to the top of the filter screen 5.

[0028] In this embodiment, while filtering, the cleaning block 7 can continuously clean the filter screen 5 through the reciprocating movement of the movable frame 301, the side wall of the collection box 601 is fixedly connected to the side wall of the transmission cylinder 4, and the inner wall of the transmission cylinder 4 is penetrated with a discharge groove 9, so that the solid waste on the surface of the filter screen 5 is pushed to the inner wall of the discharge groove 9, and the two ends of the cleaning block 7 are fixedly connected with a slider 8, and the side wall of the transmission cylinder 4 corresponding to the slider 8 is provided with a first slide groove 10, and the outer wall of the slider 8 is slidably connected to the inner wall of the first slide groove 10 The outer wall of the slider 8 corresponds to the inner wall of the slot 607. During the movement of the cleaning block 7, the slider 8 will be driven to move synchronously along the inner wall of the first slide groove 10. Then the slider 8 will contact the stopper 606. Then the outer wall of the slider 8 will slide to the inner wall of the slot 607. After that, during the movement of the slider 8, the stopper 606 will be driven to slide along the top of the filter screen 5. After sliding to a certain distance, the convex corner of the stopper 606 will fit the inner wall of the inclined groove 605, and then the inclined groove 605 will be moved. The pressing plate 603 is squeezed and driven to slide upward along the inner wall of the collecting chamber 602, and the spring 604 is compressed at the same time. The height of the sliding pressing plate 603 is higher than the side wall of the discharge slot 9. At this time, the interior of the collecting chamber 602 is connected to the interior of the transmission cylinder 4. Then, the solid waste pushed by the cleaning block 7 will fall into the interior of the collecting chamber 602 through the discharge slot 9, thereby completing the collection of the solid waste. After that, when the cleaning block 7 moves in the opposite direction, the slider 8 will disengage from the inner wall of the card slot 607, and then the spring 604 will be reset by elastic force, thereby driving the pressing plate 603 to slide downward along the inner wall of the collecting chamber 602. At this time, the interior of the collecting chamber 602 becomes a sealed space again, and then the bottom of the pressing plate 603 will squeeze the solid waste. Compressing the solid waste can make the interior of the collecting chamber 602 accommodate more solid waste. Then, the moisture of the solid waste will be squeezed out, and then flow into the interior of the conveying pipe 609 through the filter hole 608, and then flow back into the interior of the transmission cylinder 4 through the one-way valve 610.

[0029] As described above, when filtering river water, the cleaning block 7 is driven to continue to move back and forth through the movable frame 301, so that the slider 8 pushes the block 606 to squeeze the inclined groove 605, thereby driving the pressure plate 603 to slide upward along the inner wall of the collection chamber 602, and then the solid waste will fall into the interior of the collection chamber 602 through the discharge chute 9, thereby realizing the automatic collection of solid waste. By squeezing the solid waste, the effective separation of solid waste and water is achieved, and the collection chamber 602 can also accommodate more solid waste.

[0030] Working principle: First, the river water is directed to the water inlet 12, and then it flows into the inside of the drum 1 from the water inlet 12, and then the river water flows along the inner wall of the drum 1, and then when it flows to the bottom of the drum 1, it will flow into the inside of the transmission drum 4, and then it will touch the filter screen 5 during the downward flow, so that the river water is filtered by the filter screen 5, so that the solid waste in the river water is filtered and stays on the surface of the filter screen 5, thereby completing the preliminary filtration of the river water, avoiding the solid waste in the river water from affecting the subsequent filtration, and then the filtered river water will continue to flow downward, and then it will enter the inside of the hydroxyl free radical filter 13, through the hydroxyl free radical filter 13, the hydroxyl free radical filter 13 will be filtered by the filter screen 5, and the solid waste in the river water will be filtered and stay on the surface of the filter screen 5, so as to complete the preliminary filtration of the river water, and avoid the solid waste in the river water from affecting the subsequent filtration, and then the filtered river water will continue to flow downward, and then it will enter the inside of the hydroxyl free radical filter 13, and the hydroxyl free radical filter 13 will be filtered by the filter screen 5. The river water is further filtered by the strong oxidizing ability and then discharged through the drain port 14. Since the water inlet 12 is located on one side of the drum 1, it will only flow in half of the space inside the drum 1. When the river water enters the drum 1, the water flow will impact the impeller 11, and then the impeller 11 will drive the shaft 2 to rotate after being impacted. The end of the connecting shaft 304 close to the tooth groove 302 is fixedly connected to the end of the shaft 2, so that the shaft 2 will drive the connecting shaft 304 to rotate, so that the connecting shaft 304 drives the half-circle teeth 305 to rotate synchronously. Since the gear teeth of the half-circle teeth 305 are aligned with the tooth groove 302 above, the half-circle teeth 305 will rotate synchronously with the tooth groove 302. 2 matches and meshes with each other, so when the half-circle gear 305 rotates, the movable frame 301 will drive the fixed rod 307 to move synchronously through the first connecting rod 306, and at the same time, the outer wall of the connecting shaft 304 will slide in contact with the inner wall of the second sliding groove 303, so that the movable frame 301 keeps moving horizontally, and then when the half-circle gear 305 rotates the second half circle, the gear teeth of the half-circle gear 305 will match and mesh with the tooth groove 302 below, and then when the half-circle gear 305 continues to rotate, the movable frame 301 will drive the fixed rod 307 to move horizontally in the opposite direction through the first connecting rod 306, so that the movable frame 301 will move forward and backward every time the half-circle gear 305 rotates one circle. The movable frame 301 drives the second connecting rod 308 to move back and forth through the fixed rod 307, and the sliding rod 309 penetrates and slides in the transmission cylinder 4, so that the sliding rod 309 drives the fixed plate 310 to move back and forth in the transmission cylinder 4. At the same time, the fixed plate 310 drives the cleaning block 7 to slide back and forth along the upper surface of the filter screen 5. During the sliding process of the cleaning block 7, the solid garbage on the surface of the filter screen 5 is scraped and pushed, thereby ensuring that the filter screen 5 can be cleaned at the same time during the filtering process of the river water, and avoiding a large amount of solid garbage staying on the surface of the filter screen 5 and clogging the filter screen 5; While filtering the river water, the reciprocating movement of the movable frame 301 cleverly drives the cleaning block 7 to continuously clean the filter screen 5, effectively avoiding the accumulation of solid garbage on the surface of the filter screen 5. In this process, the cleaning block 7 not only pushes the solid garbage to the inner wall of the discharge chute 9, but also realizes synchronous movement in the first slide groove 10 through the slider 8 connected to it. When the slider 8 contacts the stop block 606, it cleverly slides into the slot 607 and drives the stop block 606 to slide along the top of the filter screen 5. As the sliding progresses, the convex corner of the stop block 606 gradually fits the inner wall of the inclined groove 605 and squeezes it. This squeezing action prompts the pressure plate 603 to slide on the inner wall of the collection chamber 602 and compresses the spring 604. When the height of the pressure plate 603 exceeds the side wall of the discharge chute 9, the collection chamber 602 is connected to the inside of the transmission cylinder 4. , the solid waste will smoothly fall into the collecting chamber 602 through the discharge chute 9, realizing the collection of waste. When the cleaning block 7 moves in the opposite direction, the slider 8 disengages from the card slot 607, and the spring 604 pushes the pressure plate 603 down with its elastic force, so that the collecting chamber 602 becomes a sealed space again. At this time, the bottom of the pressure plate 603 squeezes the solid waste, realizing the compression of the waste, thereby improving the accommodation capacity of the collecting chamber 602, and the compressed solid waste releases moisture, which flows into the conveying pipe 609 through the filter hole 608, and then flows back to the transmission cylinder 4 through the one-way valve 610, realizing the automatic collection of solid waste. Through effective squeezing treatment, the complete separation of solid waste and moisture is ensured, and at the same time, the storage capacity of the collecting chamber 602 for solid waste can be enhanced, making the entire filtration process more efficient and environmentally friendly.
