Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a high-efficiency surface water purification tank and purification method. Background Technology

[0002] Surface water refers to the total amount of dynamic and static water on the land surface, also known as "terrestrial water". It includes various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, ice caps, etc. Due to current environmental constraints, surface water can no longer be used directly and needs to be treated to meet drinking water standards.

[0003] Currently, the general process for treating surface water involves settling, adding chemicals for purification, settling again, and filtering. However, after adding purification agents, the surface water treatment equipment often suffers from poor mixing with the water and slow reaction time, which severely impacts the efficiency of surface water treatment. Furthermore, after the second settling, the pollutants and / or flocculants generated during the chemical reaction accumulate inside the water treatment equipment, significantly affecting its purification efficiency and lifespan. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides the following technical solution: a high-efficiency surface water purification tank, comprising a treatment tank with an externally installed inlet pipe, a drain pipe installed at the bottom of the treatment tank, a surface water treatment chamber inside the treatment tank, and a dosing and stirring assembly installed inside the surface water treatment chamber. The dosing and stirring assembly includes a rotating component, a positioning rod, and a water filtering component. The rotating component is rotatably connected to the outside of the positioning rod, the water filtering component is rotatably connected to the lower end face of the rotating component, and two sets of feeding pipes are fixedly connected to the upper end face of the rotating component.

[0006] The rotating component includes a transmission rod and a wall-cleaning ring. The two ends of the transmission rod are fixedly connected to the inner side of the wall-cleaning ring. A positioning groove is provided on the upper end face of the transmission rod. Two sets of guide columns are fixedly connected to the inner wall of the positioning groove. Several sets of drainage grooves are provided on both sides of the transmission rod. An adjusting plate is rotatably connected inside the drainage groove. Limiting baffles that are equal in number and position to the drainage grooves are fixedly connected to both sides of the transmission rod. A spring is provided between the limiting baffle and the adjusting plate. The two ends of the spring are respectively fixedly connected to the adjacent side of the limiting baffle and the adjusting plate.

[0007] As a preferred embodiment, the positioning rod is provided with two sets of guide grooves on its outside, and the size and position of the guide grooves are adapted to the guide post.

[0008] In a preferred embodiment, the feeding pipe is provided with an air pipe and a medicine pipe inside, and the air pipe is connected to the inside of the air tank, and the medicine pipe is connected to the inside of the medicine tank.

[0009] In a preferred embodiment, the water filtration component is made of an elastic material, the water filtration component is trumpet-shaped, the small opening of the water filtration component is rotatably connected to the lower end face of the rotating component, and the large opening of the water filtration component is fixedly connected to the inner wall of the surface water treatment chamber.

[0010] As a preferred embodiment, the upper surface of the water filtration component is provided with several sets of honeycomb grooves, and the inside of the honeycomb grooves is provided with fiber fluff. When the rotating component is at the lowest point of the surface water treatment chamber, the inner wall of the honeycomb grooves is in contact and fits.

[0011] In a preferred embodiment, the bottom of the draining tank is inclined, one side of the adjusting plate is in contact with the bottom of the draining tank, and the adjusting plate extends from the inside of the draining tank to the outside of the transmission rod. The area where the adjusting plate is in contact with the bottom of the draining tank and the outer wall of the outer side of the medicine tank is arc-shaped.

[0012] In a preferred embodiment, the outer wall of the adjusting plate that is in contact with the bottom of the drain tank and outside the medicine tank is convex arc-shaped. The convex arc-shaped outer wall of the adjusting plate is used to block the drain tank when the adjusting plate rotates towards the medicine tank.

[0013] In a preferred embodiment, the air trough is connected to the outside from the lower end face of the transmission rod via an aeration head.

[0014] As a preferred embodiment, a method for purifying surface water using the aforementioned high-efficiency surface water purification tank includes injecting surface water into the surface water treatment chamber through an inlet pipe, connecting the chemical pipe inside the feeding pipe to the chemical tank, adding purification agent into the chemical tank through the chemical pipe, connecting the air pipe to an air pump, injecting air into the air tank, and then aerating the bottom of the surface water treatment chamber through an aeration head. During aeration, the rotating component is driven to spirally rise along the trajectory of the guide groove. At this time, the transmission rod and the wall cleaning ring make the surface water inside the surface water treatment chamber dynamic. When the rotating component rises to the top, the air pump is turned off, allowing the rotating component to descend under its own gravity. Under the action of water resistance, the rotating component spirals downward. Slowly, the adjusting plate will squeeze the spring and rotate away from the chemical tank, creating a gap between the drain tank and the adjusting plate, allowing the purification agent inside the chemical tank to flow out. The purification agent will spiral down with the rotating part and enter the surface water for thorough mixing. After standing for a period of time, the air pump will be started, aerating the bottom of the surface water treatment chamber through the aeration head. The outlet valve will be opened, and the aeration will push the rotating part to spiral upward along the guide groove. When the positioning groove rises, it will remove the dirt adhering to the inner wall of the surface water treatment chamber. When the rotating part rises, it will pull and open the filter part and the honeycomb groove, adsorbing the dirt and flocculent produced by the purification of the surface water through the fiber fibers, so that the purified surface water can be discharged through the outlet pipe.

[0015] (ii) Beneficial effects

[0016] This invention provides a high-efficiency surface water purification tank and purification method, which has the following beneficial effects:

[0017] This invention uses an externally connected purification agent via a reagent tube and an externally connected air pump via an air pipe. The air pump blows air into the air tank through the air pipe, and then the gas is sent into the treatment tank through an aeration head. The aeration pushes a rotating component to rise along the trajectory of the guide groove, turning the originally static water in the treatment tank into a dynamic one. After the rotating component reaches its highest point, the air pump is turned off, and the rotating component will descend under the action of gravity. Under the action of water resistance, the adjusting plate will rotate outward of the transmission rod, and a gap will be created at the contact surface between the adjusting plate and the drainage tank. The purification agent will be evenly injected into the surface water as the rotating component spirals down, completing the rapid and uniform mixing of the surface water and effectively improving the surface water purification efficiency. Furthermore, after the addition of the purification agent, aeration will blow away the sediment settled on the feeding pipe and diffuse it within the surface water treatment chamber, effectively preventing the accumulation of excessive sediment on the surface of the filter components and thus avoiding blockages that could affect the drainage efficiency of the drain pipe. Additionally, a filter component made of elastic material in a funnel shape is installed. The smaller opening of the filter component is rotatably connected to the lower end face of a rotating component, while the larger opening is fixedly connected to the inner wall of the surface water treatment chamber. When the rotating component rises, the cleaning ring scrapes away the sediment from the inner wall of the surface water treatment chamber and mixes it into the reacted surface water, effectively preventing sediment from accumulating in the water. Accumulation of buildup on the inner wall of the treatment tank affects the surface water treatment effect and the service life of the treatment tank. After the rotating part rises, the filter part is stretched and opened. With the drain pipe open, the water in the surface water treatment chamber is released. At this time, the fibers inside the honeycomb cell will absorb dirt and flocculents, ensuring that the surface water discharged from the drain pipe has high cleanliness. After the rotating part descends to the lowest point, the filter part retracts. At this time, the honeycomb cell will squeeze the fibers, squeezing out the residual water in the fibers, effectively preventing excessive residual water inside the treatment tank and preventing the mixture of water and dirt from corroding the treatment tank.

Example

[0034] like Figure 1-10 As shown, this embodiment provides a surface water high-efficiency purification tank, including a treatment tank 1 with an external water inlet pipe, a drain pipe installed at the bottom of the treatment tank 1, a surface water treatment chamber inside the treatment tank 1, and a dosing and stirring assembly 2 installed inside the surface water treatment chamber. The dosing and stirring assembly 2 includes a rotating component 21, a positioning rod 22, and a water filtering component 24. The rotating component 21 is rotatably connected to the outside of the positioning rod 22, the water filtering component 24 is rotatably connected to the lower end face of the rotating component 21, and two sets of feeding pipes 23 are fixedly connected to the upper end face of the rotating component 21.

[0035] The rotating component 21 includes a transmission rod 211 and a wall cleaning ring 212. Both ends of the transmission rod 211 are fixedly connected to the inner side of the wall cleaning ring 212. A positioning groove 213 is provided on the upper end face of the transmission rod 211. Two sets of guide columns 215 are fixedly connected to the inner wall of the positioning groove 213. Several sets of drainage grooves are provided on both sides of the transmission rod 211. An adjusting plate 216 is rotatably connected inside the drainage groove. Limiting baffles 214, which are equal in number and position to the drainage grooves, are fixedly connected on both sides of the transmission rod 211. A spring 3 is provided between the limiting baffle 214 and the adjusting plate 216. The two ends of the spring 3 are respectively fixedly connected to the adjacent side of the limiting baffle 214 and the adjusting plate 216.

[0036] It should be noted that the reagent tube is used to connect to the external purification reagent, allowing the purification reagent to enter the reagent tank 217, and the air tube is used to connect to the external air pump.

[0037] Furthermore, the positioning rod 22 is provided with two sets of guide grooves 221 on the outside, and the size and position of the guide grooves 221 are adapted to the guide post 215.

[0038] Furthermore, the feed pipe 23 is equipped with an air pipe and a medicine pipe inside, with the air pipe connected to the inside of the air tank 218 and the medicine pipe connected to the inside of the medicine tank 217.

[0039] Specifically, the air pump blows air into the air tank 218 through the air pipe, and then sends the gas into the treatment tank 1 through the aeration head 219 in an aeration manner. The aeration can push the rotating part 21 to rise along the trajectory of the guide groove 221. The aeration will make the originally static water in the treatment tank 1 dynamic. After the rotating part 21 rises to the top, the air pump is turned off. The rotating part 21 will fall under the action of gravity. Under the action of water resistance, the adjusting plate 216 will rotate outward of the transmission rod 211. A gap will be generated between the contact surface of the adjusting plate 216 and the drainage groove. The purification agent will be evenly injected into the surface water as the rotating part 21 spirals down, completing the rapid and uniform mixing of the surface water and effectively improving the surface water purification efficiency. Furthermore, after the purification agent is added, the aeration will blow the sediment on the feed pipe 23 and spread it in the surface water treatment chamber. When the rotating part 21 rises, the cleaning ring 212 will scrape off the sediment on the inner wall of the surface water treatment chamber and mix it into the surface water after the reaction. This can effectively prevent the sediment from accumulating on the inner wall of the treatment tank 1, affecting the surface water treatment effect and the service life of the treatment tank 1.

[0040] It should be noted that under dynamic conditions, the mixing rate of surface water and purification agent will be faster. When there is no water inside the surface water treatment chamber, the regulating plate 216 will also rotate away from the agent tank 217 due to air resistance, and the maximum number of rotations of the rotating part 21 is 3-5 rotations.

[0041] Please see Figure 3 and 10The water filter component 24 is made of elastic material and is trumpet-shaped. The small opening of the water filter component 24 is rotatably connected to the lower end face of the rotating component 21, and the large opening of the water filter component 24 is fixedly connected to the inner wall of the surface water treatment chamber.

[0042] Furthermore, the upper surface of the water filtration component 24 is provided with several sets of honeycomb grooves, and the inside of the honeycomb grooves is provided with fiber fluff. When the rotating component 21 is at the lowest point of the surface water treatment chamber, the inner wall of the honeycomb grooves is in contact and fits.

[0043] Specifically, after the rotating part 21 rises, the water filter part 24 will be stretched and opened. With the drain pipe open, the water in the surface water treatment chamber is released. At this time, the fibers inside the honeycomb cell will adsorb dirt and flocculents, ensuring that the surface water discharged from the drain pipe has high cleanliness. After the rotating part 21 descends to the lowest point, the water filter part 24 retracts. At this time, the honeycomb cell will squeeze the fibers, squeezing out the residual water in the fibers, effectively preventing excessive residual water inside the treatment tank 1 and preventing the mixture of water and dirt from corroding the treatment tank 1.

[0044] It should be noted that if too much dirt or flocculent material adheres to the fibers inside the honeycomb cell, the fibers inside the honeycomb cell can be cleaned by raising the rotating part 21 to a fixed point, opening the drain pipe, and using a high-pressure water hose.

[0045] Please see Figure 5 and 6 The bottom of the drain tank is sloping, and one side of the adjusting plate 216 is in contact with the bottom of the drain tank. The adjusting plate 216 extends from the inside of the drain tank to the outside of the transmission rod 211. The area where the adjusting plate 216 is in contact with the bottom of the drain tank and on the outer wall of the medicine tank 217 is arc-shaped.

[0046] Furthermore, the outer wall of the adjusting plate 216, which is in contact with the bottom of the drain tank and outside the medicine tank 217, is convex arc-shaped. The convex arc-shaped outer wall of the adjusting plate 216 is used to block the drain tank when the adjusting plate 216 rotates towards the medicine tank 217.

[0047] Furthermore, the air trough 218 is connected to the outside via the aeration head 219 from the lower end face of the transmission rod 211.

[0048] This embodiment also provides a method for purifying surface water using the aforementioned high-efficiency surface water purification tank. The method includes injecting surface water into the surface water treatment chamber through an inlet pipe, connecting the chemical pipe inside the feeding pipe 23 to the chemical tank, adding purification agents into the chemical tank 217 through the chemical pipe, connecting the air pipe to an air pump, and injecting air into the air tank 218. Air is then aerated at the bottom of the surface water treatment chamber through an aeration head 219. During aeration, the rotating component 21 is driven to spirally rise along the trajectory of the guide groove 221. At this time, the transmission rod 211 and the wall cleaning ring 212 make the surface water inside the surface water treatment chamber dynamic. When the rotating component 21 reaches its highest point, the air pump is turned off, allowing the rotating component 21 to descend under its own weight. Due to water resistance, the spiral descent of the rotating component 21 is slow. The adjusting plate 216 will squeeze the spring 3 and rotate it away from the side of the agent tank 217. A gap will be created between the drain tank and the adjusting plate 216, allowing the water purification agent inside the agent tank 217 to flow out. The water purification agent will spiral down with the rotating part 21 and enter the surface water to mix thoroughly. After standing for a period of time, the air pump will be started, and aeration will be carried to the bottom of the surface water treatment chamber through the aeration head 219. The outlet pipe valve will be opened. During aeration, the rotating part 21 will be pushed to spiral up along the trajectory of the guide groove 221. When the positioning groove 213 rises, it will remove the dirt adhering to the inner wall of the surface water treatment chamber. When the rotating part 21 rises, it will pull the filter part 24 open and the honeycomb groove will open. The fiber fluff will adsorb the dirt and flocculent produced by the purification of the surface water, and the purified surface water will be discharged through the outlet pipe.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
