Description

Technical Field

[0002] Water environment refers to the environment composed of water bodies and their surrounding ecosystems, including rivers, lakes, reservoirs, and other water bodies and their surrounding biological communities. Water quality improvement of the water environment is to improve the quality of water bodies through a series of measures and technologies to make it reach or approach the national or local water quality standards, thereby protecting aquatic ecosystems and ensuring the sustainable development of human health and social economy.

[0003] In the process of improving the water quality in urban rivers, flotation machines are often used to remove pollutants such as suspended matter, grease, and colloid substances in urban rivers. However, during the operation of the existing flotation machines, the treated pollutants and impurities float to the upper surface of the water in the flotation machines. Subsequently, a scraper is often used to scrape and clean the impurities on the water surface. As the scraper scrapes the impurities on the water surface, the impurities accumulate and become thicker. The impurities can easily break away from the contact with the scraper through the lower side of the scraper, resulting in incomplete cleaning of the suspended impurities on the water surface. The subsequent reciprocating movement of the scraper can also easily cause the bubbles attached to the impurities to break away, causing the impurities to sink back into the water, resulting in poor pollutant treatment effect.

DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly introduced below. Obviously, the drawings in the following description only relate to some embodiments of the present invention, but are not intended to limit the present invention.

[0029] In the process of using an air flotation machine to treat water in a river channel, it is not easy for the scraper in a traditional air flotation machine to scrape off all the floating flocculants and impurities at one time. At the same time, the scraper moves back and forth to drive away the flocculants and impurities, which easily causes the impurities to sink back into the water, resulting in poor water treatment effect. If the scraper used is too long and inserted into the water, it is easy to cause too much water to be discharged from the slag discharge port, resulting in a waste of clean water resources and an increase in the subsequent treatment load of flocculants and impurities.

[0030] Embodiment 1: A water quality improvement device for water environment maintenance, see Figure 1-Figure 4 As shown, it includes a box body 1, and a flocculant adding tank, a conduit and a pump body are arranged on the right side of the box body 1, which are used to uniformly add flocculants to the sewage in the box body 1. A control panel is arranged on the box body 1 (the control panel is electrically connected to the following electrical components), and a baffle 11 and a baffle 2 12 are installed on the right side of the box body 1. The baffle 2 12 is located on the left side of the baffle 1 11. The baffle 1 11 and the baffle 2 12 cooperate with the box body 1 to guide the flow medium to flow in a serpentine trajectory. A stirring unit 13, an air flotation unit 14 and a driving unit 15 are installed on the box body 1. The stirring unit 13 and the air flotation unit 14 are all existing structures. The stirring unit 13 is composed of a stirring frame, a transmission shaft, a driving motor and a gear box. The stirring unit 13 is used to stir the flowing medium between the box body 1 and the baffle 1 11. The air flotation unit 14 is composed of an air pump, a pipeline, and a releaser (nozzle). The air flotation unit 14 is used to spray air between the baffle 1 11 and the baffle 2 12. The driving unit 15 is composed of a driving motor, two rotating shafts and two sets of sprocket chains (the chains are illustrated by belts in the figure). The outer sides of the two chains on the driving unit 15 are equipped with two centrally symmetrical fixing frames 16, and the fixing frames 16 are slidably provided with a collecting The elastic sheet 2 for collecting the suspended impurities in the box body 1 is set as an elastic plastic sheet. The side of the elastic sheet 2 away from the adjacent fixing frame 16 is arc-shaped. The elastic sheet 2 is provided with a bottom support mechanism for supporting the suspended impurities in the box body 1. The bottom support mechanism is used to reduce the occurrence of the flocculant impurities sinking back into the water, thereby improving the water treatment effect of the device. The baffle plate 1 11 is provided with a diffusion mechanism for uniformly distributing the impurities between it and the baffle plate 2 12 in the flowing medium, which assists the flocculant impurities to adhere evenly to the tiny bubbles, thereby helping the flocculants generated in the water to float up quickly, thereby improving the water treatment effect of the device. The device improves the efficiency and effect of water purification. A baffle plate 3 17 is fixedly connected to the left part of the box body 1. A drainage cavity 18 for discharging the treated flowing medium is arranged on the left part of the box body 1. The baffle plate 3 17 is located on the right side of the drainage cavity 18. A drainage pipe is installed on the left side of the box body 1. The drainage pipe is connected to the drainage cavity 18. The movement of the elastic sheet 2 and the arc structure of the elastic sheet 2 are utilized to ensure that during the movement of the elastic sheet 2, all the flocculants and impurities on the water surface are attached to the left side of the lower elastic sheet 2, thereby improving the scraping and separation effect of the flocculants and impurities on the water surface, thereby ensuring the cleanliness of the discharged water.

[0031] See also Figure 3-Figure 6As shown, the bottom-covering mechanism includes a fixed plate 21, which is fixedly connected to a side of the elastic sheet 2 away from the adjacent fixed frame 16. The fixed plate 21 is slidably provided with a sliding baffle 22, and the sliding baffle 22 is provided with an inclined surface. The sliding baffle 22 cooperates with the adjacent elastic sheet 2 and the adjacent fixed plate 21 to form a hook shape, which is used to reduce the sinking of suspended impurities. A plurality of tension springs are installed between the sliding baffle 22 and the adjacent fixed plate 21, and a plurality of elastic strips 23 are evenly distributed. The elastic strips 23 are leaf springs, which are used to support the elastic sheet 2 and reduce the deformation degree of the elastic sheet 2, thereby increasing the service life of the elastic sheet 2. An inclined scraper 24 is fixedly connected to the box body 1, and the left part of the scraper 24 is lower than the right part thereof. The scraper 24 is used to clean impurities attached to the adjacent elastic sheet 2. An inclined surface is provided on the right side of the scraper 24. The inclined surface of the scraper 24 is used to guide the sliding baffle 22 to pass through the scraper 24. The scraper 24 is located between the box body 1 and the baffle three 17 to form a slag discharge A slag discharge pipe is installed on the front side of the box body 1 directly above the cavity. The slag discharge pipe is connected to the slag discharge cavity composed of the box body 1 and the baffle three 17. The upper part of the baffle three 17 is inclined, and the left part of the inclined side of the baffle three 17 is higher than its right part. The inclined side of the baffle three 17 and the scraper 24 are in contact with the corresponding elastic sheet 2 and the adjacent sliding baffle 22. The fixed frame 16 is slidingly provided with two L-shaped rods 25 symmetrically distributed front and back. The two adjacent L-shaped rods 25 front and back are fixedly connected to the adjacent elastic sheet 2. A plurality of tension springs are installed between the elastic sheet 2 and the adjacent fixed frame 16. Two guide rods 26 symmetrically distributed front and back are installed on the upper part of the box body 1. The guide rods 26 are inclined and used to control the corresponding elastic sheet 2 to extend at a uniform speed on the adjacent fixed frame 16. The guide rods 26 are squeezed and matched with the adjacent L-shaped rods 25. According to the pollution degree of the water in the river channel, the inclination degree of the guide rods 26 is adjusted to assist the elastic sheet 2 in scraping and collecting flocculants and impurities, thereby improving the applicability and practicality of the device.

[0032] In the process of treating the water in the river, the operator uses a water pump to pump the sewage in the river into the right part of the box 1, and at the same time, the operator injects a certain amount of flocculant into the storage tank, and then the operator evenly injects the flocculant in the storage tank into the box 1 and starts the stirring unit 13, the air flotation unit 14 and the driving unit 15 through the control panel, wherein the stirring unit 13 works to evenly mix the flocculant with the sewage pumped into the box 1, and after mixing, the flocculant treats the impurities in the sewage, so that the impurities in the sewage form floccules, and then the floccules and water flow To between baffle 1 11 and baffle 2 12, at this time, the flotation unit 14 works to spray tiny bubbles, the tiny bubbles float up and attach to the flocs, and then the flocs gradually float to the surface of the water driven by the water flow and the tiny bubbles, and the treated water flows to the left part of the box 1, and then the water is discharged back into the river through the drainage cavity 18. If there are specific pollutants in the sewage in the river, the existing treatment unit is installed on the drainage pipe connected to the drainage cavity 18 on the box 1, so that the water is discharged back into the river after being treated, thereby completing the improvement of the water quality in the river.

[0033] During the above-mentioned process of improving the water quality in the river channel, the flocs formed by impurities in the water are located on the water surface on the right side of the box body 1, wherein the control panel controls the driving unit 15 to work, and the chain in the driving unit 15 will drive the two fixed frames 16 to rotate clockwise. When the fixed frame 16 rotates close to the water surface, the fixed frame 16 drives the adjacent elastic sheet 2, the adjacent fixed plate 21 and the adjacent sliding baffle 11 to move together, wherein the elastic sheet 2 is located in the water to drive the flocs on the water surface, and at the same time, the two L-shaped rods 25 on the fixed frame 16 move to the lower side of the two guide rods 26, and then the fixed frame 16 drives the connected parts to move to the left, wherein the sliding baffle 22 in this area lifts the suspended impurities attached to the lower elastic sheet 2 to prevent the impurities from being re-suspended in the water under the driving action of the corresponding elastic sheet 2, thereby improving the separation effect of the device on floc impurities in water.

[0034] During the movement of the two L-shaped rods 25 at the lower side under the two guide rods 26, since the two guide rods 26 are arranged at an angle, the two guide rods 26 will gradually squeeze the two L-shaped rods 25 moving at the lower side, so that the two L-shaped rods 25 at the lower side drive the adjacent elastic sheets 2 to move downward, and the elastic sheets 2 move and stretch the connected tension springs, ensuring that all flocculants and impurities on the water surface are located in the hook-shaped structure composed of the elastic sheet 2, the fixed plate 21 and the sliding baffle 22, ensuring the cleanliness of the treated water, thereby improving the effect of the device on improving the water quality in the river.

[0035] After the lower elastic sheet 2 moves to the left until the lower sliding baffle 22 fits the vertical side of the baffle three 17, the elastic sheet 2 continues to move to the left, and the elastic sheet 2 bends in the opposite direction, and drives the flocculent impurities through the upper inclined surface of the baffle three 17 into the slag discharge cavity formed by it and the box body 1. The subsequent flocculent impurities are discharged through the slag discharge pipe connected to the slag discharge cavity formed by the box body 1 and the baffle three 17. In this process, the lower elastic sheet 2 is limited and squeezed by the baffle three 17 on the lower elastic sheet 2, and the lower elastic strip 23 is bent and deformed, wherein the bent and deformed elastic sheet 2 will fit the scraper 24, and the scraper 24 scrapes and cleans the left side of the lower elastic sheet 2, so that all the flocculent impurities enter the slag discharge cavity formed by the box body 1 and the baffle three 17, and the fixed frame 1 on the lower side. 6 continues to drive the connected parts to move. As the sliding baffle 22 fits the scraper 24, the scraper 24 squeezes the corresponding sliding baffle 22, so that the sliding baffle 22 moves relative to the adjacent fixed plate 21 and stretches the connected tension spring. Subsequently, the lower elastic sheet 2 drives the connected parts to pass through the scraper 24. Under the elastic action of the elastic strip 23, the tension of the tension spring connected to the sliding baffle 22 and the tension of the tension spring connected to the elastic sheet 2, the parts on the fixed frame 16 return to their initial state. Then, the above operation is repeated. The parts on the two fixed frames 16 alternately clean the flocculants and impurities on the water surface. After the device has worked for a period of time, the improvement of the water quality of the river is completed. The control panel turns off the electrical components in the device. When the water quality needs to be improved again, the above operation can be repeated.

[0036] During the above-mentioned impurity cleaning process, the operator adjusts the inclination angle of the guide rod 26 according to the severity of the water pollution environment in the river channel, ensuring that the elastic sheet 2, the adjacent fixed plate 21 and the adjacent sliding baffle 22 are adaptable to scrape and clean the flocculent impurities on the treated water surface, thereby improving the applicability of the device.

[0037] In the process of sewage treatment by the existing flotation machine, the flocculant and sewage in the flotation machine are evenly mixed to form a large amount of flocs. Then, when the flocs in the sewage flow into the flotation area, a large amount of flocs in the sewage gather at the corners, affecting the attachment of tiny bubbles in the flotation machine to the flocs, thereby affecting the floating rate of the flocs and affecting the sewage treatment efficiency of the traditional flotation machine. At the same time, with the accumulation of a large amount of flocs, it is easy to cause the flocs to block the nozzles in the flotation machine, affecting the sewage treatment of the flotation machine.

The evenly distributed air guide pipes 1 3 and the evenly distributed air guide pipes 2 4 are staggered and arranged to guide the suspended impurities to diffuse evenly between the baffle 1 11 and the baffle 2 12. The air guide pipe 2 4 is provided with a plurality of groups of jet ports distributed equidistantly in the circumferential direction, and a one-way valve is installed on the jet ports of the air guide pipe 2 4. The jet ports on the evenly distributed air guide pipe 1 3 and the jet ports on the evenly distributed air guide pipe 2 4 The diameters of the ports are gradually reduced from bottom to top, so that the jet range of the jet of the jet of all the air guide pipes 13 and all the air guide pipes 24 from bottom to top gradually becomes larger, all the air guide pipes 24 are connected with the air supply unit 31, and a power output unit 41 is installed on the box body 1, and the air guide pipe 24 at the bottom is transmitted to the adjacent air guide pipe 13 through a transmission unit 142, and the transmission unit 142 is composed of four mutually meshing gears. The transmission of the transmission unit 142 makes the rotation direction of the air guide pipe 24 opposite to the rotation direction of the air guide pipe 13, and the power output unit 41 and the transmission unit 142 cooperate to drive all the air guide pipes 13 and all the air guide pipes 24 to rotate together, and the power output unit 41 is driven by a driving motor , and are composed of multiple groups of pulleys and belts, each group of pulleys and belts is used to drive two upper and lower adjacent air guide pipes 3 (or two upper and lower adjacent air guide pipes 2 4), the curvature of the air guide pipe 3 located outside the baffle 1 1 is larger than the curvature between the two adjacent groups of jet ports thereon, and is used for intermittent jetting of multiple groups of jet ports on the air guide pipe 3, the curvature of the air guide pipe 2 4 located outside the baffle 2 12 is smaller than the curvature between the two adjacent groups of jet ports thereon, and is used to drive suspended impurities to float up, and the rotation of all the air guide pipes 1 3 and all the air guide pipes 2 4 is used to control the blowing mode and blowing range of the ejected gas, thereby helping to evenly disperse the flocculants and impurities in the water and quickly float up, thereby improving the treatment efficiency of the device for river water.

[0039] See also Fig. 9 and Fig.11As shown, the blowing assembly includes a sliding frame 5, which is slidably arranged on a baffle 11, and two symmetrical buoyancy members 51 are installed on the lower side of the sliding frame 5.

The transmission unit 2 54 is composed of two rotating shafts, a bevel gear set, a pulley and a belt. This structure is only a single display. A separate power unit can be used here to drive the rotating tube 52 to rotate. The left part of the sliding frame 5 is fixedly connected with a fixed shell 55 sleeved on the outside of the rotating tube 52. The fixed shell 55 is provided with a plurality of evenly distributed arc holes. The arc holes of the fixed shell 55 are connected and matched with the corresponding air jets on the rotating tube 52, and the arc holes on the fixed shell 55 gradually increase in width from top to bottom. The arc holes on the fixed shell 55 block the corresponding air jets on the rotating tube 52, thereby changing the blowing force and blowing range of the gas ejected from the air jets on the rotating tube 52, helping the flocculant impurities on the water surface to move to the left, and making the flocculant impurities evenly distributed on the water surface, avoiding the flocculant impurities from sinking into the water again.

[0040] In the process of improving the water quality in the river channel, the control panel starts the air supply unit 31 and the power output unit 41 at the same time, wherein the air supply unit 31 works to make multiple air guide pipes 1 3, multiple air guide pipes 2 4 and the air jets on a sliding frame 5 to spray together, wherein the air jets on the air guide pipe 1 3 spray gas to blow the flocculent impurities in the water between the baffle 1 11 and the baffle 2 12, so that the impurities are diffused between the baffle 1 11 and the baffle 2 12, ensuring that the tiny bubbles generated in the air flotation unit 14 are evenly attached to the flocculent impurities, thereby improving the floating efficiency of the flocculent impurities in the water, and at the same time, because the air jets on the multiple air guide pipes 1 3 are reduced from bottom to top, under the action of the constant pressure air pump in the air supply unit 31, the blowing force and blowing range of the gas sprayed from the air jets on the multiple air guide pipes from bottom to top gradually increase, so that the flocculent impurities in the water are spread to different degrees to attach and combine with the tiny bubbles sprayed by the air flotation unit 14, thereby ensuring the stability of the floating efficiency of the flocculent impurities.

[0041] During the jetting process of the multiple air guide pipes 3, the power output unit 41 works through the pulley, belt and transmission unit 2 54 to make all the air guide pipes 1, all the air guide pipes 24 and the rotating tube 52 rotate together, wherein the rotation direction of the air guide pipe 13 is opposite to that of the air guide pipe 24 due to the transmission of the gear set in the transmission unit 2 54. At the same time, since the curvature of the air guide pipe 3 located outside the baffle 11 is greater than the curvature between the two adjacent groups of jet ports thereon, during the rotation of the air guide pipe 3, the jet ports distributed circumferentially on the air guide pipe 3 alternately jet, and finally the multiple air guide pipes 3 on the baffle 11 continuously jet to blow away the flocculants and impurities in the water, and spread the flocculants and impurities.

[0042] During the rotation of the plurality of air guide pipes 24, the air jets on the air guide pipe 24 that are not in contact with the baffle plate 212 eject gas, and because the curvature of the air guide pipe 24 located outside the baffle plate 212 is smaller than the curvature between two adjacent groups of air jets, the air guide pipe 24 rotates so that the air jets distributed circumferentially thereon perform alternating intermittent jetting, wherein during the jetting process, the corresponding air jets on the air guide pipe 24 eject gas to drive the flocs attached with tiny bubbles to float up, and the air jets distributed circumferentially on the air guide pipe 24 eject gas intermittently, so that the flocs in the water float up in layers, and the flocs are prevented from accumulating in the water, thereby intermittently prompting the floc impurities in the water to attach to the tiny bubbles in all directions, thereby helping the floc impurities to float up quickly, and improving the sewage treatment efficiency of the device.

[0043] The power output unit 41 works and simultaneously makes the rotation direction of the rotating tube 52 the same as that of the air guide tube 1 3 through the transmission unit 2 54. The two buoyancy members 51 rely on their own buoyancy in the water to keep the sliding frame 5 on the water surface. At this time, the air supply unit 31 works to fill the rotating tube 52 with gas through the connecting tube 53. When the corresponding jet port on the rotating tube 52 faces the corresponding arc-shaped hole on the fixed shell 55, the jet port on the rotating tube 52 blows the water surface. The rotating tube 52 rotates so that the jet port on it gradually approaches the upper end of the adjacent arc-shaped hole. In this process, the arc-shaped hole gradually blocks the corresponding jet port, so that the rotating tube 52 is in the swinging process. The flow cross-sectional area of ​​the jet port on the rotating tube 52 gradually becomes smaller, that is, at this time, the blowing distance of the gas ejected from the jet port on the rotating tube 52 gradually becomes longer, and the gas ejected from the jet port on the rotating tube 52 blows and drives away the flocculent impurities floating on the water surface, helping the flocculent impurities on the water surface to move to the left, so that the subsequent fixed frame 16 repeats the above action to scrape and clean the flocculent impurities, thereby further improving the treatment efficiency and treatment effect of the device for the water in the river channel. After improving the water quality of the river channel for a period of time, the control panel turns off the electrical components in the device, and the above operation can be repeated when the water quality needs to be improved again.

[0044] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
