Description

Technical Field

[0001] This invention relates to the field of river and lake management technology, specifically to a natural purification device for river and lake management. Background Technology

[0002] Water pollution refers to the phenomenon where a certain amount of pollutants, such as sewage, wastewater, and various wastes, enter a water body, exceeding its self-purification and pollution-carrying capacity. This leads to adverse changes in the physical and chemical properties and biological community composition of the water body and its sediment, damaging the inherent ecosystem and function of the water body, thus reducing its usability. Natural purification of rivers and lakes refers to a governance model that utilizes the physical, chemical, and biological characteristics of the water body itself and its surrounding ecosystem, through natural processes or with minimal artificial assistance, to achieve pollutant degradation, water quality improvement, and ecological function restoration. Its core is relying on the self-regulating capacity of the natural ecosystem, reducing dependence on artificial chemical intervention and mechanical engineering, and achieving "restoring natural clarity through natural means," which is one of the core directions of current river and lake ecological restoration. Purification equipment is required in river and lake management.

[0003] Currently, existing river and lake treatment and purification equipment requires power sources such as motors and drives, which not only increases energy consumption but is also not conducive to long-term operation, easily causing equipment damage and failing to fully utilize the natural advantages of flowing water. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: A natural purification device for river and lake management, comprising: A connecting base frame, and a guide plate fixedly installed on the side of the connecting base frame surface; A water treatment mechanism that uses the impact of flowing water to naturally purify river and lake water. The water treatment mechanism is installed on the surface of the connecting base frame and on the side away from the guide plate. The water treatment mechanism includes a volute housing and a pretreatment assembly. The inlet of the volute housing is fixedly installed on the side of the connecting base surface. The pretreatment assembly is installed at the inlet of the volute housing's inner cavity. A rotating shaft is rotatably installed at the center of the volute housing's inner cavity. The top end of the rotating shaft penetrates the bottom of the volute housing's inner cavity and extends to its exterior. An impeller is fixedly connected to the outer circular surface of the rotating shaft. A V-shaped plate is fixedly connected to the middle of the impeller's surface. A turning wheel is fixedly installed at the top end of the rotating shaft. A first arc-shaped... The filter screen has a cover plate installed on the top side of the volute shell. The purification equipment is installed in the designated location for river and lake treatment by connecting the base frame. The inclined installation of the symmetrical guide plates on both sides can guide the water of the river and lake that needs to be treated, so that the water can enter the inlet of the volute shell. The inlet of the volute shell is conical, which increases the flow rate of the water entering the volute shell, thereby increasing the amount of water entering the volute shell. The suspended solids in the water can be filtered out by the first arc-shaped filter screen. The water then passes through the first arc-shaped filter screen, so that the water flows smoothly. The top of the snail-shaped shell is equipped with a granular reagent feeding mechanism.

[0005] Preferably, the guide plates are installed at an angle, there are two guide plates, and the two guide plates are installed symmetrically along the central axis in the middle of the connecting base frame, the rotating shaft is installed vertically, and the water inlet of the volute shell is conical.

[0006] As water enters the volute shell, the impeller blades are subjected to the impact force of the fluid. Supported by the rotation of the rotating shaft, the impeller blades rotate in a circle, which agitates the water entering the volute shell. This causes the suspended debris intercepted by the first arc-shaped filter screen to move along the inner wall. The suspended debris is always in a state of movement, making it less likely for debris to accumulate.

[0007] Preferably, the impeller blades are arc-shaped and evenly distributed on the outer surface of the rotating shaft. The V-shaped plate is installed vertically, and the opening of the V-shaped plate faces the inner wall of the volute shell.

[0008] Preferably, the pretreatment component includes a rectangular sleeve and a guide post. The rectangular sleeve is fixedly installed at the water inlet position on the top of the volute shell. The guide post is slidably installed on the top of the volute shell through the rectangular sleeve. The guide post passes through the center of the rectangular sleeve, and its bottom end extends into the interior of the water inlet of the volute shell. A herringbone-shaped barrier is fixedly connected to the bottom end of the guide post. Both ends of the herringbone-shaped barrier are fixedly connected to baffles. Floating blocks are fixedly connected to the inner side of the herringbone-shaped barrier. Under the guidance of the guide plate, water carrying debris comes into contact with the herringbone-shaped barrier, and the debris floating on the water surface is intercepted, thus performing preliminary treatment on the water and achieving the effect of pretreatment. This avoids the accumulation of debris and blockage, which is beneficial for subsequent river and lake management.

[0009] Preferably, the guide pillars are installed vertically, and there are four guide pillars evenly distributed at the water inlet position on the top of the volute shell. The end of the baffle away from the herringbone-shaped barrier is attached to the inner wall of the water inlet of the volute shell. The floating blocks are evenly distributed on the inner side of the herringbone-shaped barrier. By contacting the water surface, the floating blocks are buoyed and float, thus keeping the herringbone-shaped barrier in a suspended state. As the water level rises and falls, and guided by the guide pillars, the herringbone-shaped barrier changes with the water level. The bottom of the herringbone-shaped barrier is always inside the water, while the top of the herringbone-shaped barrier is always above the water surface. By fully utilizing the rise and fall of the water level, the height of the herringbone-shaped barrier can be freely adjusted, thereby further helping to effectively intercept debris floating on the water surface.

[0010] Preferably, the granular reagent feeding mechanism includes a strip-shaped shell. The bottom of the strip-shaped shell is fixedly installed to the top of the volute-shaped shell via support legs. A guide pipe connects the discharge port at the bottom of the strip-shaped shell to the top of the volute-shaped shell. A discharge hopper is fixedly installed on the side of the top of the strip-shaped shell. An arc-shaped inclined plate is fixedly connected to the inlet position at the bottom of the inner cavity of the strip-shaped shell, near the top of the guide pipe. A first notched wheel is rotatably installed on the side of the inner cavity of the strip-shaped shell. A second notched wheel is rotatably installed on the inner cavity of the strip-shaped shell, away from the first notched wheel. A right-angle tooth is fixedly connected to the central shaft at the bottom of the second notched wheel. A steel wire ring is installed between the first and second notched wheels. A pusher plate is fixedly connected to the surface of the steel wire ring. A conveying cylinder is fixedly connected to the side of the inner wall of the strip-shaped shell. Opening the valve at the bottom of the discharge hopper allows the granular reagent material to flow into the conveying cylinder. The impeller blades are impacted by the fluid, causing them and the rotating shaft to rotate together. The actuating wheel rotates along with the shaft, applying a driving force to the right-angle teeth, which in turn rotates the second notched wheel. Supported by the rotation of the first notched wheel, and connected in series with the pusher discs by a steel wire ring, the pusher discs, evenly distributed on the surface of the steel wire ring, mesh with the first and second notched wheels, causing the steel wire ring and pusher discs to rotate together. The movement of the pusher discs pushes the granular reagent material in the conveying cylinder towards the drainage pipe, allowing it to flow downwards within the pipe. The granular reagent then comes into contact with the water at the inlet of the volute casing, purifying the water. This process fully utilizes the impact of the fluid to achieve natural purification.

[0011] Preferably, the first notched rotary wheel is installed directly above the drainage tube, the right-angled teeth are evenly distributed at the central axis of the bottom of the second notched rotary wheel, and the right-angled teeth are engaged with the teeth on the top of the actuating wheel.

[0012] The pusher discs are evenly distributed on the surface of the wire ring, and as the wire ring drives the pusher discs to rotate continuously, the pusher discs enter the interior of the conveying cylinder one by one. This allows the granular reagents falling into the conveying cylinder to be pushed in an orderly manner, preventing clogging of the granular reagents and ensuring that the granular reagents come into uniform contact with the water, further promoting the treatment of the water.

[0013] Preferably, the discharge port at the bottom of the discharge bin is connected to the inlet at the top of the conveying cylinder, the first notched roller and the second notched roller are installed at the same height, the wire ring passes through the center of the conveying cylinder, and the pusher is evenly distributed on the surface of the wire ring.

[0014] Preferably, an impurity collection component is installed at the middle of the surface of the first arc-shaped filter screen. The impurity collection component includes an arc-shaped collection shell. The inlet of the arc-shaped collection shell is fixedly installed on the surface of the first arc-shaped filter screen. A second arc-shaped filter screen is fixedly connected to the end of the arc-shaped collection shell away from the first arc-shaped filter screen. A top cover is detachably fixedly installed at the top of the arc-shaped collection shell. A flow guiding plate is fixedly connected to the inlet of the inner cavity of the arc-shaped collection shell. A hook-shaped plate is fixedly connected to the inner cavity of the arc-shaped collection shell near the flow guiding plate. As the impeller blades agitate the water inside the volute shell, the suspended impurities filtered by the first arc-shaped filter screen move along the inner wall. Under the guidance of the flow guiding plate, the suspended impurities enter from the space between the flow guiding plate and the inlet of the arc-shaped collection shell. As the suspended impurities enter the arc-shaped collection shell, they can be collected. Furthermore, the cooperation between the hook-shaped plate and the flow guiding plate prevents the suspended impurities entering the arc-shaped collection shell from flowing back, thereby effectively collecting the suspended impurities.

[0015] Preferably, the arc-shaped collection shells are evenly distributed on the surface of the first arc-shaped filter screen, and the drainage plate and hook plate are both installed vertically.

[0016] This invention provides a natural purification device for river and lake management. It has the following beneficial effects: I. This natural purification equipment for river and lake management utilizes symmetrical guide plates installed at an angle on both sides to guide the water in the river and lake that needs treatment. This facilitates the water entering the inlet of the volute-shaped shell. The conical inlet of the volute-shaped shell increases the flow rate of the water entering the shell, thereby increasing the volume of water entering the shell. This allows the suspended solids in the water to be filtered out through the first arc-shaped filter screen. The water then passes through the first arc-shaped filter screen, ensuring smooth water flow.

[0017] Second, this natural purification equipment used for river and lake management, under the guidance of the guide plate, allows the water carrying debris to come into contact with the herringbone-shaped barrier net, intercepting the debris floating on the water surface, thus performing preliminary treatment on the water and achieving the effect of pretreatment. This avoids the accumulation of debris and blockage, which is beneficial for subsequent river and lake management.

[0018] Third, this natural purification device for river and lake management utilizes floating blocks that come into contact with the water surface, causing the blocks to float and thus suspend the A-shaped barrier net. As the water level rises and falls, and guided by the guide columns, the A-shaped barrier net changes with the water level. The bottom of the A-shaped barrier net is always inside the water, while the top is always above the water surface. By fully utilizing the rise and fall of the water level, the height of the A-shaped barrier net can be freely adjusted, thereby further helping to effectively intercept floating debris on the water surface.

[0019] Fourth, this natural purification device for river and lake management, as water enters the interior of the volute shell, causes the impeller blades to be impacted by the fluid. Under the rotational support of the rotating shaft, the impeller blades rotate in a circle, which can agitate the water entering the volute shell. This causes the suspended debris intercepted by the first arc-shaped filter screen to move along the inner wall. The suspended debris is always in a state of movement, and it is not easy for debris to accumulate.

[0020] V. This natural purification device for river and lake management utilizes a turning wheel to apply a turning force to the right-angle teeth, causing the second notched rotating wheel to rotate. Combined with a steel wire ring, the pusher discs are connected in series. The pusher discs, evenly distributed on the surface of the steel wire ring, mesh with the first and second notched rotating wheels, causing the steel wire ring and pusher discs to rotate together. Through the movement of the pusher discs, the granular reagent in the conveying cylinder is pushed towards the drainage pipe, allowing the granular reagent to flow downwards within the drainage pipe. The granular reagent comes into contact with the water at the inlet of the volute-shaped outer shell, purifying the water. This fully utilizes the impact of the fluid to achieve natural purification.

[0021] VI. This natural purification equipment for river and lake management uses a pusher plate evenly distributed on the surface of a steel wire ring. As the steel wire ring drives the pusher plate to rotate continuously, the pusher plate enters the interior of the conveying cylinder one by one, thus orderly pushing the granular reagent that falls into the conveying cylinder. This prevents granular reagent from clogging and ensures that the granular reagent comes into uniform contact with the water, further promoting the treatment of the water.

[0022] VII. This natural purification equipment for river and lake management, as the impeller blades agitate the water inside the volute-shaped outer shell, the suspended debris filtered by the first arc-shaped filter moves along the inner wall and, under the guidance of the flow-guiding plate, enters through the space between the flow-guiding plate and the inlet of the arc-shaped collection shell. As the suspended debris enters the arc-shaped collection shell, it can be collected. Furthermore, the cooperation between the hook-shaped plate and the flow-guiding plate prevents the suspended debris entering the arc-shaped collection shell from flowing back, thus effectively collecting the suspended debris.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: A natural purification device for river and lake management, comprising: A connecting base frame 1, and a guide plate 2 fixedly installed on the side of the surface of the connecting base frame 1; The water treatment mechanism 4 uses the impact of flowing water to naturally purify the river and lake water. The water treatment mechanism 4 is installed on the surface of the connecting base frame 1 and on the side away from the guide plate 2. The water treatment mechanism 4 includes a volute housing 41 and a pretreatment component 42. The inlet of the volute housing 41 is fixedly installed on the side of the connecting base 1. The pretreatment component 42 is installed at the inlet of the inner cavity of the volute housing 41. A rotating shaft 43 is rotatably installed at the center of the inner cavity of the volute housing 41. The top end of the rotating shaft 43 passes through the bottom of the inner cavity of the volute housing 41 and extends to its outside. An impeller blade 44 is fixedly connected to the outer circular surface of the rotating shaft 43. A V-shaped plate 45 is fixedly connected to the middle of the surface of the impeller blade 44. A push wheel 46 is fixedly installed at the top end of the rotating shaft 43. A first arc-shaped filter is fixedly connected to the arc-shaped surface of the volute housing 41. The top side of the spiral shell 41 is equipped with a cover plate 48. The purification equipment is installed in the designated location for river and lake treatment by connecting the base frame 1. The inclined installation of the symmetrical guide plates 2 on both sides can guide the water of the river and lake to be treated, so that the water can enter the inlet of the spiral shell 41. The conical shape of the inlet of the spiral shell 41 increases the flow rate of the water entering the spiral shell 41, thereby increasing the amount of water entering the spiral shell 41. The suspended solids in the water can be filtered out by the first arc-shaped filter screen 47. The water then passes through the first arc-shaped filter screen 47, making the water flow smoothly. The top of the snail-shaped outer shell 41 is equipped with a granular reagent feeding mechanism 3.

[0027] The guide plate 2 is installed at an angle. There are two guide plates 2, and the two guide plates 2 are installed symmetrically along the central axis of the connecting base frame 1. The rotating shaft 43 is installed vertically, and the inlet of the volute shell 41 is a cone-shaped funnel.

[0028] As water enters the volute shell 41, the impeller blades 44 are subjected to the impact force of the fluid. Under the rotational support of the rotating shaft 43, the impeller blades 44 rotate in a circle, which can agitate the water entering the volute shell 41. This causes the suspended debris intercepted by the first arc-shaped filter screen 47 to move along the inner wall. The suspended debris is always in a state of movement, and it is not easy for debris to accumulate.

[0029] The impeller blades 44 are arc-shaped and are evenly distributed on the outer surface of the rotating shaft 43. The V-shaped plate 45 is installed vertically, and the opening of the V-shaped plate 45 faces the inner wall of the volute shell 41.

[0030] The pretreatment component 42 includes a rectangular sleeve 421 and a guide post 422. The rectangular sleeve 421 is fixedly installed at the water inlet position on the top of the volute housing 41. The guide post 422 is slidably installed on the top of the volute housing 41 through the rectangular sleeve 421. The guide post 422 passes through the center of the rectangular sleeve 421 and extends to the inside of the water inlet of the volute housing 41. A herringbone-shaped barrier 423 is fixedly connected to the bottom of the guide post 422. Both ends of the herringbone-shaped barrier 423 are fixedly connected to baffles 424. A floating block 425 is fixedly connected to the inner side of the herringbone-shaped barrier 423. Under the guidance of the guide plate 2, the water carrying debris comes into contact with the herringbone-shaped barrier 423. The debris floating on the surface of the water is intercepted, thus performing preliminary treatment on the water and preventing the accumulation of debris from causing blockage.

[0031] Four guide posts 422 are installed vertically and are evenly distributed at the water inlet position at the top of the volute-shaped outer shell 41. The end of the baffle 424 away from the herringbone-shaped barrier 423 is attached to the inner wall of the water inlet of the volute-shaped outer shell 41. Floating blocks 425 are evenly distributed on the inner side of the herringbone-shaped barrier 423. By contacting the water surface, the floating blocks 425 are buoyed and float, thus allowing the herringbone-shaped barrier 423 to be lifted. In a suspended state, as the water level rises and falls, and guided by the guide column 422, the herringbone net 423 changes with the water level. The bottom of the herringbone net 423 is always inside the water, while the top of the herringbone net 423 is always above the water surface. By making full use of the rise and fall of the water level, the height of the herringbone net 423 can be freely adjusted, thereby further helping to effectively intercept debris floating on the water surface.

[0032] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The granular reagent feeding mechanism 3 includes a strip-shaped shell 31. The bottom of the strip-shaped shell 31 is fixedly installed to the top of the volute-shaped shell 41 via support legs. A guide pipe 32 connects the discharge port at the bottom of the strip-shaped shell 31 to the top of the volute-shaped shell 41. A discharge hopper 33 is fixedly installed on the side of the top of the strip-shaped shell 31. An arc-shaped inclined plate 34 is fixedly connected to the bottom of the inner cavity of the strip-shaped shell 31 near the top of the guide pipe 32. A first notched wheel 35 is rotatably installed on the side of the inner cavity of the strip-shaped shell 31. A second notched wheel 36 is rotatably installed on the inner cavity of the strip-shaped shell 31 away from the first notched wheel 35. A right-angle tooth 37 is fixedly connected to the central shaft at the bottom of the second notched wheel 36. A steel wire ring 38 is installed between the first notched wheel 35 and the second notched wheel 36. A pusher plate 39 is fixedly connected to the surface of the steel wire ring 38. A conveying cylinder 310 is fixedly connected to the side of the inner wall of the strip-shaped shell 31. The operator opens the discharge... The valve at the bottom of the hopper 33 allows the granular reagent material in the discharge hopper 33 to flow into the conveying cylinder 310. The impeller 44 is impacted by the fluid, causing it and the rotating shaft 43 to rotate together. The actuating wheel 46 rotates with the rotating shaft 43, applying a driving force to the right-angle teeth 37, which in turn causes the second notched wheel 36 to rotate. Supported by the rotation of the first notched wheel 35, and connected in series with the pusher disc 39 via the wire ring 38, the pusher disc 39, evenly distributed on the surface of the wire ring 38, meshes with the first notched wheel 35 and the second notched wheel 36, causing the wire ring 38 and the pusher disc 39 to rotate together. The movement of the pusher disc 39 pushes the granular reagent in the conveying cylinder 310 towards the drainage pipe 32, allowing the granular reagent to flow downwards within the drainage pipe 32. The granular reagent then comes into contact with the water at the inlet of the volute shell 41, purifying the water.

[0033] The first notched rotary wheel 35 is installed directly above the drainage tube 32, and the right-angle teeth 37 are evenly distributed at the central axis of the bottom of the second notched rotary wheel 36, and the right-angle teeth 37 are engaged with the teeth on the top of the actuating wheel 46.

[0034] The pusher discs 39 are evenly distributed on the surface of the wire ring 38. As the wire ring 38 drives the pusher discs 39 to rotate continuously, the pusher discs 39 enter the interior of the conveying cylinder 310 one by one. This allows the granular reagent falling into the conveying cylinder 310 to be pushed in an orderly manner, preventing clogging of the granular reagent. It also ensures that the granular reagent comes into uniform contact with the water, further promoting the treatment of the water.

[0035] The discharge port at the bottom of the discharge bin 33 is connected to the inlet at the top of the conveying cylinder 310. The first notched roller 35 and the second notched roller 36 are installed at the same height. The wire ring 38 passes through the center of the conveying cylinder 310, and the pusher plate 39 is evenly distributed on the surface of the wire ring 38.

[0036] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 9 As shown: An impurity collection assembly 5 is installed at the middle of the surface of the first arc-shaped filter screen 47. The impurity collection assembly 5 includes an arc-shaped collection shell 51. The inlet of the arc-shaped collection shell 51 is fixedly installed on the surface of the first arc-shaped filter screen 47. A second arc-shaped filter screen 52 is fixedly connected to the end of the arc-shaped collection shell 51 away from the first arc-shaped filter screen 47. A top cover 53 is detachably fixedly installed at the top of the arc-shaped collection shell 51. A flow guiding plate 54 is fixedly connected to the inlet of the inner cavity of the arc-shaped collection shell 51. A hook-shaped plate is fixedly connected to the inner cavity of the arc-shaped collection shell 51 near the flow guiding plate 54. 55. As the impeller blades 44 agitate the water inside the volute casing 41, the suspended debris filtered by the first arc-shaped filter screen 47 moves along the inner wall and, under the guidance of the flow-guiding plate 54, enters through the space between the flow-guiding plate 54 and the feed inlet of the arc-shaped collection shell 51. As the suspended debris enters the arc-shaped collection shell 51, it can be collected. Furthermore, the cooperation between the hook-shaped plate 55 and the flow-guiding plate 54 prevents the suspended debris entering the arc-shaped collection shell 51 from flowing back, thus effectively collecting the suspended debris.

[0037] The arc-shaped collection shell 51 is evenly distributed on the surface of the first arc-shaped filter screen 47, and the flow guiding plate 54 and hook plate 55 are both installed vertically.

[0038] In use, the purification equipment is first installed at the designated location for river and lake treatment by connecting the base frame 1, and an appropriate amount of granular reagent material is loaded into the discharge bin 33. The guide plates 2 on both sides are installed at an angle to guide the water of the river and lake that needs to be treated, so that the water can enter the inlet of the volute shell 41. The inlet of the volute shell 41 is cone-shaped, which increases the flow rate of the water entering the volute shell 41, thereby increasing the amount of water entering the volute shell 41. Furthermore, under the guidance of the guide plate 2, the water carrying debris comes into contact with the herringbone-shaped barrier 423, and the debris floating on the surface of the water is intercepted, which can perform preliminary treatment of the water and prevent the accumulation of debris from causing blockage. Simultaneously, by utilizing the contact between the floating block 425 and the water surface, the floating block 425 is buoyed and floats, thus keeping the V-shaped barrier net 423 in a suspended state. As the water level rises and falls, and guided by the guide column 422, the V-shaped barrier net 423 changes with the water level. The bottom of the V-shaped barrier net 423 is always inside the water, while the top of the V-shaped barrier net 423 is always above the water surface. By fully utilizing the rise and fall of the water level, the height of the V-shaped barrier net 423 can be freely adjusted, thereby further facilitating the effective interception of floating debris on the water surface. As water enters the volute shell 41, suspended solids in the water are filtered out by the first arc-shaped filter 47. The water then passes through the first arc-shaped filter 47, allowing for smooth water flow. The impeller 44 is subjected to the impact force of the fluid and rotates in a circular motion under the support of the rotating shaft 43. This agitates the water entering the volute shell 41, causing the suspended solids intercepted by the first arc-shaped filter 47 to move along the inner wall. The suspended solids are always in motion, making it less likely for them to accumulate. The staff opens the valve at the bottom of the discharge hopper 33, allowing the granular reagent material in the discharge hopper 33 to flow into the conveying cylinder 310. The impeller 44 is impacted by the fluid, causing the impeller 44 and the rotating shaft 43 to rotate together. The actuating wheel 46 rotates with the rotating shaft 43. The actuating wheel 46 applies a driving force to the right-angle teeth 37, which causes the second notched wheel 36 to rotate. Supported by the rotation of the first notched wheel 35, and combined with the wire ring 38 connecting the pusher plate 39 together, the pusher plate 39, which is evenly distributed on the surface of the wire ring 38, meshes with the first notched wheel 35 and the second notched wheel 36, so that the wire ring 38 and the pusher plate 39 operate together. Through the movement of the pusher plate 39, the granular reagent in the conveying cylinder 310 is pushed towards the drainage pipe 32, so that the granular reagent flows downward in the drainage pipe 32. The granular reagent comes into contact with the water in the inlet of the volute shell 41, purifying the water. The pusher discs 39 are evenly distributed on the surface of the wire ring 38. As the wire ring 38 drives the pusher discs 39 to rotate continuously, the pusher discs 39 enter the interior of the conveying cylinder 310 one by one. This allows the granular reagents falling into the conveying cylinder 310 to be pushed in an orderly manner, preventing clogging of the granular reagents. It also ensures that the granular reagents are in uniform contact with the water, further promoting the treatment of the water. Furthermore, as the impeller blades 44 agitate the water inside the volute casing 41, the suspended debris filtered by the first arc-shaped filter screen 47 moves along the inner wall and, under the guidance of the flow-guiding plate 54, enters through the space between the flow-guiding plate 54 and the feed inlet of the arc-shaped collection shell 51. As the suspended debris enters the arc-shaped collection shell 51, it can be collected. Moreover, the cooperation between the hook-shaped plate 55 and the flow-guiding plate 54 prevents the suspended debris entering the arc-shaped collection shell 51 from flowing back, thus effectively collecting the suspended debris. The top cover 53 can be opened to remove the debris intercepted and filtered by the second arc-shaped filter screen 52.
