Description

Technical Field

[0001] This invention relates to the field of water purification reactor technology, and specifically to a composite water purification reactor for decarbonization and phosphorus removal. Background Technology

[0002] Carbon and phosphorus removal are crucial steps in water treatment, aiming to remove carbon and phosphorus from water to reduce eutrophication and improve water quality. Carbon removal primarily refers to the removal of organic or inorganic carbon from water. In wastewater treatment, chemical agents are added to react with carbon in the water, generating precipitates or gases, thereby removing carbon from the water. The goal is to reduce the organic matter content in the water, lower chemical oxygen demand (COD) and biochemical oxygen demand (BOD), and prevent organic matter from decomposing in the water and consuming oxygen, leading to water quality deterioration. Phosphorus removal targets phosphorus in the water. Phosphorus is one of the main nutrients in eutrophication; excessive phosphorus can lead to the proliferation of algae, affecting water quality. Water purification reactors are key equipment in water treatment systems used to remove impurities and improve water quality. By adding chemical agents, pollutants in the water react chemically to generate insoluble precipitates or gases, which are then removed from the water through solid-liquid separation or gas-liquid separation.

[0003] When water purification reactors remove carbon and phosphorus from water using chemical reagents, the reaction is often insufficient, resulting in some unreacted carbon and phosphorus remaining in the water and precipitating out. The resulting precipitates are not easily removed in the water purification reactor. Therefore, we propose a composite water purification reactor for carbon and phosphorus removal. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a composite water purification reactor for carbon and phosphorus removal, comprising a water purifier housing, an inlet pipe connected to the outer surface of the water purifier housing, a feed pipe I opened at the top of the water purifier housing, a feed cover I threadedly connected to the end of the feed pipe I away from the water purifier housing, a feed pipe II opened at the top of the water purifier housing, a feed cover II threadedly connected to the end of the feed pipe II away from the water purifier housing, a stirring device fixedly connected to the top of the water purifier housing, a filter device fixedly connected to the inner wall of the water purifier housing, an outlet pipe connected to the outer surface of the water purifier housing, a filter screen fixedly connected to the inner wall of the outlet pipe, a discharge device rotatably connected to the inner wall of the water purifier housing, a discharge pipe connected to the outer surface of the water purifier housing, a bottom of the stirring device rotatably connected to the top of the filter device, and a side of the filter device fixedly connected to one side of the discharge device.

[0005] The stirring device includes a motor, with a rotating rod fixedly connected to the motor's drive shaft. An annular plate is fixedly connected to the outer surface of the rotating rod, and an upper connecting plate is fixedly connected to the inner side of the annular plate. An arc-shaped long plate is fixedly connected to the bottom of the annular plate, and a brush is fixedly connected to one side of the arc-shaped long plate. During rotation, the arc-shaped long plate drives the brush to rotate, cleaning the inner wall of the water purifier's casing and effectively preventing scale formation. An annular plate is fixedly connected to the bottom of the arc-shaped long plate, and a lower connecting plate is fixedly connected to the inner side of the annular plate. A rubber scraper is fixedly connected to the bottom of the lower connecting plate, which also drives the rubber scraper to scrape the filter plates (filter plate one and filter plate two), effectively preventing sediment from clogging the filter plates before purification is complete, thus ensuring a stable water flow rate and accelerating the purification speed. A spiral plate is fitted and fixedly connected to the outer surface of the rotating rod; the rotation of the spiral plate generates a spiral-like flow. The dynamic flow field not only enhances the contact and collision of reactants, but also causes the generated precipitates to move towards the edge and deposit under the action of centrifugal force, and move downward along the trajectory of the spiral plate, thereby accumulating solid reactants on the surface of the filter plate. A circular sleeve block is fitted and fixedly connected to the outer surface of the rotating rod, and an agitator is fixedly connected to the outer surface of the circular sleeve block. The rotation of the spiral plate fixed to the surface of the rotating rod and the agitator at the bottom accelerates the reaction between water and chemical reagents and makes the reaction more complete. The output end of the motor is fixedly connected to the top of the water purifier box. One end of the rotating rod passes through the top of the water purifier box and is rotatably connected to the top of the water purifier box. The end of the upper connecting plate away from the arc-shaped long plate is fixedly connected to the outer surface of the rotating rod, and the end of the lower connecting plate away from the arc-shaped long plate is fixedly connected to the outer surface of the rotating rod. Multiple agitators are provided, and the multiple agitators are distributed on the outer surface of the arc-shaped sleeve block.

[0006] Furthermore, the filtration device includes a hollow cylinder, with a motor fixedly connected to the inner wall of the cylinder. The drive shaft of the motor is fixedly connected to the cylinder. One end of the cylinder passes through and is fixedly connected to a filter plate one. The rotation of filter plate one scrapes away the sediment on the surface of filter plate two, thus preventing clogging of the filter screen. One end of the cylinder passes through and is rotatably connected to filter plate two. An inclined plate is fixedly connected to the side of filter plate two near filter plate one. Falling sediment is guided by the inclined plate to the opening created by the rotation of semicircular plate one, ensuring smooth discharge of sediment and preventing sediment from falling onto the surface of semicircular plate two, thereby avoiding potential clogging and cleaning problems. One end of the cylinder passes through and is fixedly connected to semicircular plate one, and one end of the cylinder passes through and is rotatably connected to semicircular plate two. A scraper is rotatably connected to the top of filter plate one. Purified water is discharged from the outlet pipe, while sediment is filtered by the filter plates. The sediment is deposited on the surface of the filter plate. The drive shaft of the motor starts to rotate, driving the first filter plate and the first semi-circular plate to rotate. During the rotation of the first filter plate, it passes by the scraper, which pushes the sediment on the surface of the first filter plate to easily fall off, avoiding the accumulation and clogging of sediment, and ensuring the continuous and efficient operation of the filter plate. The bottom of the hollow cylinder is fixedly connected to the inner wall of the water purifier box. The outer surface of the second filter plate is fixedly connected to the inner wall of the water purifier box. The outer surface of the second semi-circular plate is fixedly connected to the inner wall of the water purifier box. The end of the scraper away from the cylinder is fixedly connected to the inner wall of the water purifier box. The outer surface of the hollow cylinder is rotatably connected to one side of the discharge device. The outer surface of the cylinder is fixedly connected to one side of the discharge device. One end of the cylinder passes through the inclined plate and is rotatably connected to the inclined plate. The first filter plate is a semi-circular plate with multiple round holes on its surface. The second filter plate is a semi-circular plate with multiple round holes on its surface.

[0007] Furthermore, the discharge device includes a folding rod, the bottom of which is fixedly connected to a rectangular inclined plate. When the sediment completely falls to the bottom of the inner wall of the water purifier tank, the motor starts to accelerate, driving the cylinder to rotate, which in turn causes the rectangular inclined plate fixed to the folding rod to rotate as well. The rotation of the rectangular inclined plate generates a strong centrifugal force, scraping up the sediment near the center, preventing the sediment from accumulating and solidifying. A rectangular hole is opened on one side of the rectangular inclined plate. The scraped sediment moves along the inclined surface of the rectangular inclined plate to the rectangular hole, bringing the sediment closer to the discharge port for easy discharge and preventing the sediment from spreading randomly inside the tank. A scraper is fixedly connected to one side of the rectangular inclined plate. During the rotation, the scraper also scrapes the inner wall of the tank, preventing sediment residue from remaining on the inner wall of the tank. A connecting rod is fixedly connected to one side of the rectangular inclined plate, and an inclined push plate is fixedly connected to the side of the connecting rod away from the rectangular inclined plate. The inclined push plate rotates and scrapes up the sediment accumulated on the periphery. During the rotation of the inclined push plate, the sediment is subjected to an upward thrust and gradually moves upward. Under the push of the inclined push plate, the sediment rotates and moves to the discharge pipe and is smoothly discharged through the discharge port, ensuring the smooth discharge of sediment and avoiding the accumulation and residue of sediment at the bottom of the tank. The side of the scraper away from the rectangular inclined plate is rotatably connected to the inner wall of the water purifier tank, and the side of the inclined push plate is rotatably connected to the inner wall of the water purifier tank. The end of the folded rod away from the rectangular inclined plate is fixedly connected to the outer surface of the cylinder, and the side of the rectangular inclined plate away from the scraper is rotatably connected to the outer surface of the hollow cylinder.

[0008] The beneficial effects of this invention are as follows:

[0009] 1. This invention accelerates the reaction between water and chemical reagents by rotating a spiral plate fixed to the surface of a rotating rod and a stirring paddle at the bottom, making the reaction more complete. The purified water is discharged from the outlet pipe, while the sediment is filtered by the filter plate and deposited on the surface of the filter plate. The drive shaft of the motor starts to rotate, driving the first filter plate and the first semi-circular plate to rotate. During the rotation of the first filter plate, it passes by a scraper, which pushes the sediment on the surface of the first filter plate to easily fall off, avoiding the accumulation and blockage of sediment, and ensuring the continuous and efficient operation of the filter plate. When the sediment has completely fallen to the bottom of the inner wall of the water purifier tank, the motor starts to accelerate the rotation, driving the cylinder to rotate, which in turn causes the rectangular inclined plate fixed on the folded rod to rotate as well. The rotation of the rectangular inclined plate generates a strong centrifugal force, scraping up the sediment near the center, avoiding the accumulation and solidification of sediment, and improving cleaning efficiency.

[0010] 2. This invention, by setting up a stirring device, accelerates the reaction between water and chemical reagents by rotating a spiral plate fixed on the surface of the rotating rod and a stirring paddle at the bottom, making the reaction more complete. The rotation of the spiral plate generates a spiral-like flow field, which not only enhances the contact and collision of reactants, but also causes the generated precipitates to move towards the edge and deposit under the action of centrifugal force, and move downward along the trajectory of the spiral plate, thereby accumulating solid reactants on the surface of the filter plate. During the rotation, the arc-shaped long plate drives the brush to rotate, realizing the cleaning of the inner wall of the water purifier tank, effectively preventing the formation of scale. The lower connecting plate also drives the rubber scraper to scrape the first and second filter plates, effectively preventing the precipitates from clogging the filter plates before the water purification is completed, thereby ensuring the stability of the water flow rate and accelerating the water purification speed.

[0011] 3. This invention, through the installation of a filtration device, allows purified water to be discharged from the outlet pipe, while sediment is filtered by the filter plate and deposited on its surface. The drive shaft of the motor rotates, causing the first filter plate and the first semi-circular plate to rotate. During the rotation of the first filter plate, it passes by a scraper, which easily removes the sediment from its surface, preventing sediment accumulation and clogging, and ensuring the continuous and efficient operation of the filter plate. At the same time, the rotation of the first filter plate also scrapes away sediment from the surface of the second filter plate, preventing clogging of the filter screen. The fallen sediment is guided by the inclined plate to the opening created by the rotation of the first semi-circular plate, ensuring smooth discharge of sediment and preventing sediment from falling onto the surface of the second semi-circular plate, thereby avoiding potential clogging and cleaning problems.

[0012] 4. This invention, through the setting of a discharge device, when the sediment completely falls to the bottom of the inner wall of the water purifier tank, the motor starts to accelerate and rotate, driving the cylinder to rotate, which in turn causes the rectangular inclined plate fixed on the folded rod to rotate as well. The rotation of the rectangular inclined plate generates a strong centrifugal force, scraping up the sediment near the center, preventing the sediment from accumulating and solidifying. The scraped sediment moves along the inclined surface of the rectangular inclined plate to the rectangular hole, bringing the sediment closer to the discharge port for easy discharge, preventing the sediment from spreading randomly inside the tank. The inclined push plate rotates and scrapes up the sediment accumulated on the periphery. During the rotation of the inclined push plate, the sediment is pushed upward and gradually moves upward. Under the push of the inclined push plate, the sediment rotates and moves to the discharge pipe and is smoothly discharged through the discharge port, ensuring the smooth discharge of sediment and preventing the sediment from accumulating and remaining at the bottom of the tank. The scraper also scrapes the inner wall of the tank during the rotation process, preventing sediment residue on the inner wall of the tank. Attached Figure Description

In use, sewage enters the water purifier housing 1 from the inlet pipe 2. The feed cover 4 is opened, and sodium hydroxide is added from the feed pipe 3. It reacts with water to produce carbonate precipitate. Aluminum salt is added through feed pipe 5 to feed cover 26.

[0025] Second embodiment, please refer to Figures 1-8 This invention provides a composite water purification reactor for carbon and phosphorus removal: a filtration device 8 includes a hollow cylinder 801, an electric motor 802 fixedly connected to the inner wall of the hollow cylinder 801, a cylinder 803 fixedly connected to the drive shaft of the electric motor 802, a filter plate 804 passing through and fixedly connected to one end of the cylinder 803, a filter plate 805 passing through and rotatably connected to one end of the cylinder 803, an inclined plate 806 fixedly connected to the side of the filter plate 805 near the filter plate 804, a semi-circular plate 807 passing through and fixedly connected to one end of the cylinder 803, a semi-circular plate 808 passing through and rotatably connected to one end of the cylinder 803, and a scraper 809 rotatably connected to the top of the filter plate 804. The bottom of 801 is fixedly connected to the inner wall of the water purifier box 1. The outer surface of the second filter plate 805 is fixedly connected to the inner wall of the water purifier box 1. The outer surface of the second semicircular plate 808 is fixedly connected to the inner wall of the water purifier box 1. The end of the scraper 809 away from the cylinder 803 is fixedly connected to the inner wall of the water purifier box 1. The outer surface of the hollow cylinder 801 is rotatably connected to one side of the discharge device 11. The outer surface of the cylinder 803 is fixedly connected to one side of the discharge device 11. One end of the cylinder 803 passes through the inclined plate 806 and is rotatably connected to the inclined plate 806. The first filter plate 804 is a semicircular plate with multiple round holes on its surface. The second filter plate 805 is a semicircular plate with multiple round holes on its surface.

[0026] The discharge device 11 includes a folded rod 1101, with a rectangular inclined plate 1102 fixedly connected to the bottom of the folded rod 1101. A rectangular hole 1103 is provided on one side of the rectangular inclined plate 1102. A scraper 1104 is fixedly connected to one side of the rectangular inclined plate 1102. A connecting rod 1105 is fixedly connected to one side of the rectangular inclined plate 1102. An inclined push plate 1106 is fixedly connected to the side of the connecting rod 1105 away from the rectangular inclined plate 1102. The side of the scraper 1104 away from the rectangular inclined plate 1102 rotates with the inner wall of the water purifier housing 1. The inclined push plate 1106 is rotatably connected to the inner wall of the water purifier housing 1. The end of the folded rod 1101 away from the rectangular inclined plate 1102 is fixedly connected to the outer surface of the cylinder 803. The side of the rectangular inclined plate 1102 away from the scraper 1104 is rotatably connected to the outer surface of the hollow cylinder 801. In use, after the purified water is discharged from the outlet pipe 9, the sediment is deposited on the surface of filter plate 804 and filter plate 805. The drive shaft of the motor 802 rotates, causing filter plate 804 and semi-circular plate 807 to rotate. As filter plate 804 rotates, the sediment on its surface is pushed off by scraper 809. Filter plate 804 then scrapes away the sediment on filter plate 805. The fallen sediment is guided by inclined plate 806 and enters the bottom of the inner wall of the water purifier housing 1 through the opening created by the rotation of semicircular plate 807, preventing sediment from falling onto the surface of semicircular plate 808. When the sediment has completely fallen to the bottom of the inner wall of the water purifier housing 1, motor 802 accelerates its rotation, driving cylinder 803 to rotate and fix it to the folding rod 1. The rectangular inclined plate 1102 on 101 rotates accordingly. The centrifugal force generated by the rotation of the rectangular inclined plate 1102 scrapes up the sediment near the center. The sediment moves along its inclined surface to the position of the rectangular hole 1103. After moving to the position of the rectangular hole 1103, it accumulates on the periphery and is scraped up by the rotating inclined push plate 1106. During the rotation, it is pushed upward by the inclined push plate and gradually moves upward. When it rotates to the discharge pipe 12, the sediment is discharged through the discharge pipe 12. The scraper 1104 scrapes the inner wall of the tank during rotation to prevent sediment residue.

[0027] In operation, wastewater enters the water purifier housing 1 through inlet pipe 2. Inlet cover 4 is opened, and sodium hydroxide is added through inlet pipe 3, reacting with water to produce carbonate precipitate. Inlet cover 6 is opened, and aluminum salt is added through inlet pipe 5, reacting with phosphate ions in the water to produce insoluble phosphate precipitate. Stirring device 7 is activated to ensure a more complete reaction, rotating the resulting solid to the bottom. The solid precipitate passes through filter device 8, remaining at the top. After decarbonization and phosphorus removal, the water is discharged through filter screen 10 from outlet pipe 9. Once the water is drained, discharge device 11 is activated, rotating filter device 8 to scrape off the solid precipitate, which falls to the bottom of the inner wall of water purifier housing 1. The rotation of discharge device 11, through centrifugal force, pushes... As the moving solids gradually move, they are discharged from the discharge pipe 12. After sodium hydroxide and aluminum salts enter the water purifier housing 1, the motor 701 starts and rotates, driving the rotating rod 702 to rotate. The spiral plate 710 fixed on the surface of the rotating rod 702 and the stirring paddle 712 at the bottom rotate accordingly, accelerating the reaction between water and chemical reagents and making the reaction more complete. The spiral flow field generated by the rotation of the spiral plate 710 causes the precipitate to move towards the edge and deposit under the action of centrifugal force, and move downward along the trajectory of the spiral plate 710. The upper connecting plate 704 and the lower connecting plate 708 connect the annular plate 1 703 and the annular plate 2 707 to the rotating rod 702. During rotation, the arc-shaped long plate 705 drives the brush 706 to rotate, cleaning the inner wall of the water purifier housing 1. To prevent scale buildup, the lower connecting plate 708 drives the rubber scraper 709 to scrape the filter plates 804 and 805, preventing sediment from clogging the filter plates before purification is complete and slowing down the water flow rate. After the purified water is discharged from the outlet pipe 9, sediment accumulates on the surfaces of filter plates 804 and 805. The drive shaft of the motor 802 rotates, causing filter plates 804 and the semi-circular plate 807 to rotate. As filter plate 804 rotates, the sediment on its surface is pushed off by the scraper 809. Filter plate 804 rotates to scrape the sediment off the surface of filter plate 805. The fallen sediment is guided by the inclined plate 806 and enters the water purifier housing 1 through the opening created by the rotation of the semi-circular plate 807. At the bottom of the wall, to prevent sediment from falling onto the surface of the semi-circular plate 808, when the sediment has completely fallen to the bottom of the inner wall of the water purifier tank 1, the motor 802 accelerates and rotates, driving the cylinder 803 to rotate. The rectangular inclined plate 1102 fixed on the folded rod 1101 rotates accordingly. The centrifugal force generated by the rotation of the rectangular inclined plate 1102 scrapes up the sediment near the center. The sediment moves along its inclined surface to the position of the rectangular hole 1103. After moving to the position of the rectangular hole 1103, it accumulates on the periphery and is scraped up by the rotation of the inclined push plate 1106. During rotation, it is pushed upward by the inclined push plate and moves to the discharge pipe 12. The sediment is discharged through the discharge pipe 12. The scraper 1104 scrapes the inner wall of the tank during rotation to prevent sediment residue.
