Description

Technical Field

[0001] The invention relates to the technical field of phosphorus removal, and in particular to a river front-type phosphorus removal device based on an overflow low dam. Background Art

[0002] Phosphorus pollution is the main cause of river eutrophication. In small river water bodies, excess phosphorus mainly comes from various agricultural non-point source pollution sources such as fertilizers, agricultural waste, domestic sewage, livestock manure and aquaculture wastewater. After natural water bodies accept these wastewaters, the amount of nutrients such as phosphorus in the water increases, resulting in a serious deterioration of water quality, posing a threat to my country's rural living environment, agricultural ecological environment quality and water environment quality, especially a serious threat to the safety of drinking water sources. The necessity of phosphorus removal: In addition to controlling agricultural non-point source pollution sources, eutrophication of water bodies can also be effectively prevented by reducing the phosphorus content in water bodies. However, deep treatment of river water bodies (including physical, chemical and biological methods) has the problems of high cost and large water volume, and is not economically feasible. Characteristics and applications of overflow low dams: It is worth noting that according to statistics, only a few percent of rivers in the country are more than one meter deep, and the rest are less than one meter. Overflow low dams are widely used. According to the structural characteristics of the overflow low dam, the chemical adsorption method is adopted, which has the advantages of simple structure, low energy consumption and large adsorption capacity. It can effectively reduce the phosphorus content in small river water bodies and plays an important role in maintaining the water ecological environment.

[0003] At present, most of the phosphorus removal methods on the market use the addition of chemical substances for precipitation or the use of polymer semipermeable membranes to separate phosphorus. Such phosphorus removal methods are inefficient, low-cost, and troublesome to maintain. This device uses hematite as the filter material. Hematite can fix the free phosphorus in the water to achieve the phosphorus removal effect. Hematite does not react with the phosphorus in the water, and does not produce other substances. The process of adsorbing phosphorus is a physical reaction. At the same time, the devices on the market lack filtering devices. Large objects accumulated near the device will reduce the filtering effect. At the same time, it is more troublesome to clean up. There is a lack of treatment methods for materials such as mud and sand in the water. Long-term mud and sand accumulation also shortens the maintenance cycle of the device and reduces the phosphorus removal effect. At the same time, similar products are mostly driven by increasing the power source, which increases the difficulty and cost of maintenance. Summary of the invention

At the same time, the side of the separation tank is connected with a collection device for effectively collecting and processing the precipitated solid waste for subsequent treatment, and the side of the sedimentation tank is provided with an inlet pipe, which is responsible for guiding the water flow into the sedimentation tank. In order to ensure the stability of the overall structure of the sedimentation tank and the optimization of the liquid inlet and outlet process, a fourth bracket is fixedly connected to one side of the inlet pipe. The bracket not only increases the stability of the structure, but also is tightly connected to the guide plate through the side. The design of the guide plate further optimizes the direction and velocity of the water flow, slows down the water flow speed, and thus enhances the sedimentation effect. There is an outlet pipe connected along the side of the sedimentation tank away from the end of the water inlet pipe. The outlet pipe is reasonably designed to ensure that the water body is smoothly discharged from the sedimentation tank after sedimentation treatment.

In addition, the top of the sedimentation tank is designed to be flush with the top of the guide plate.

This type of paddle device is usually used in hydroelectric power generation systems, water pump systems or other industrial equipment that requires liquid flow control. Its core purpose is to convert liquid power into mechanical energy to drive other mechanical components to operate. First, the water inlet box is the basic component of the entire device, and multiple key mechanical components are installed on it. The water inlet box can accommodate the inflowing liquid and realize the control of liquid flow through the internal mechanism. This box is usually made of high-strength materials to cope with fluid pressure and external impact. On the inner wall of the water inlet box, there is a key rotating connection component - the third shaft. This shaft is one of the core transmission parts of the entire system. The power blades set on it are used to directly contact the fluid and rotate under its power. The shape and material selection of the power blades are very important to ensure that it can effectively convert the liquid power into the rotational power of the shaft under high efficiency. The input end of the transmission mechanism is fixedly connected to the third shaft at the opposite end of the power blade. The gear mechanism is an extremely precise transmission device that transmits power from one component to another through the meshing between gears, and can adjust the direction and speed of rotation. The gear mechanism housing not only protects the internal gears from the external environment, but also provides additional support to ensure the stability of the gear mechanism. In the setting of the gear mechanism, the gear shaft bracket plays a vital supporting role. The existence of these brackets ensures that the gear shaft will not be offset due to external force or its own weight during operation, thereby maintaining the efficient operation of the entire system.

This precise design not only increases the contact area and reduces friction, but also effectively ensures that the dephosphorization box can operate stably and efficiently during operation. Especially when replacing or cleaning the dephosphorization box, this design provides great convenience. It is worth noting that the inner wall of the dephosphorization box is also fixedly connected with an inner box handle, which not only provides convenience but also enhances the safety of operation. For operators, the design of the handle makes the movement and maintenance of the device easier. In addition, both sides of the dephosphorization box are fixedly connected with a filter frame. This symmetrical design not only meets the requirements of mechanical stability, but also makes the filtration process more efficient. Inside the filter frame, the fixedly connected metal grid plays a vital role. The use of metal mesh can not only withstand high chemical and physical stresses, but also effectively intercept larger solid particles during the filtration process. This design starts from the corrosion resistance and filtration particle size of the material to ensure that various complex water qualities can be handled. At the bottom of the inner wall of the filter box, the fixedly connected guide block is another innovative design. The presence of the guide block can effectively optimize the path of the water flow and improve the filtration efficiency of the entire device. In addition, the side of the filter box is connected to the return pipe. This design can realize the recycling of water flow, reduce the waste of resources, and be more environmentally friendly. Finally, the top of the filter box is also fixedly connected to the bottom of the water inlet box. This interactive connection structure ensures that the dephosphorization device can be easily integrated with other water treatment systems to achieve a more comprehensive water treatment solution. This top and bottom connection method not only increases the stability of the system, but also optimizes the efficiency of water introduction and discharge.

[0013] The present invention provides a river front phosphorus removal device based on overflow low dam. It has the following beneficial effects: 1. The river pre-type phosphorus removal device based on overflow low dam adopts hematite as the filter element material, which is conducive to the attachment of phosphorus elements, and the hematite can be reused after chemical treatment or high-temperature treatment, thereby improving the purification efficiency and reducing the phosphorus removal cost compared with the traditional method.

[0014] 2. The river pre-phosphorus removal device based on the overflow low dam uses a rotary filtering method to separate large particles in the water, such as branches and leaves, and other objects with greater impact, and place them in a designated device to filter the water and extend the maintenance cycle.

The river pre-phosphorus removal device based on overflow low dam adopts passive sedimentation method in the sedimentation device, so that the silt and other materials with higher density in the water body are precipitated, thereby realizing the separation of water and silt and other materials, and the separated silt enters the collection device for unified treatment. At the same time, the purified water is conducive to phosphorus removal and prolongs the maintenance period of the phosphorus removal device.

[0016] 4. The river pre-phosphorus removal device based on overflow low dam uses a paddle device that utilizes the gravitational potential energy of water from top to bottom to drive, and transmits power through a gear transmission mechanism, thereby driving the filter device to filter. Compared with the method of directly adding a driving device, the paddle device reduces maintenance costs and maintenance difficulties, while extending the maintenance cycle. At the same time, it automatically increases the speed when the water flow is large, and slows down when the water flow is low, thereby achieving automatic adjustment.

[0017] 5. The river pre-type phosphorus removal device based on the overflow low dam uses a reflux device to collect large particles in the water body. At the same time, the filtered water re-enters the filter device along the reflux pipe for filtration, thereby purifying the water body, which is beneficial to the phosphorus removal of the overall water body by the phosphorus removal device.

[0022] The filtering device 2 comprises a rotating chassis 21, a first filtering frame 22 is fixedly connected to the side of the rotating chassis 21, a first filter screen 23 is fixedly connected to the inner wall of the first filtering frame 22, a second filtering frame 24 is fixedly connected to the bottom of the first filtering frame 22, a filter plate 25 is fixedly connected to the inner wall of the second filtering frame 24, an output end of a gear transmission mechanism 28 is fixedly connected to the bottom of the rotating chassis 21, a first bevel gear 210 is fixedly connected to the input end of the gear transmission mechanism 28, and a filter screen 23 is fixedly connected to the inner wall of the first filtering frame 22.

It realizes the separation of large particles in the water body and the automatic collection of large particles, thereby realizing the automatic separation of large particles in the water body.

[0024] Embodiment 2: See also Figure 1-Figure 12 On the basis of the first embodiment, the present invention provides a technical solution: the sedimentation device 3 comprises a sedimentation tank 31, the bottom of the sedimentation tank 31 is fixedly connected with a separation tank 32, the side of the separation tank 32 is connected with a collecting device 33, the sides of the sedimentation tank 31 are respectively connected with a water inlet pipe 34 and a water outlet pipe 36, the side of the sedimentation tank 31 located between the water inlet pipe 34 and the water outlet pipe 36 is fixedly connected with a fourth bracket 35, the side of the sedimentation tank 31 away from the end of the water inlet pipe 34 is connected, the top of the sedimentation tank 31 is fixedly connected with an adjusting device 37, the end of the water inlet pipe 34 away from the sedimentation tank 31 is connected with the water outlet hole 17, the side of the fourth bracket 35 is fixedly connected with the side of the guide plate 11, the bottom of the water outlet pipe 36 is connected with the top of the paddle device 4, and the top of the sedimentation tank 31 is flush with the top of the guide plate 11.

[0025] The adjusting device 37 includes an adjusting bracket 371 and a baffle bin 375, the top of the adjusting bracket 371 is penetrated by and threadedly connected with an adjusting screw 372, the top of the adjusting screw 372 is fixedly connected with a handle turntable 373, the bottom of the adjusting screw 372 is rotatably connected with an adjusting baffle 374, the baffle bin 375 is fixedly connected to the inner wall of the separation tank 32, the adjusting baffle 374 is arranged on the inner wall of the baffle bin 375 and is slidably connected to the baffle bin 375, the bottom of the adjusting bracket 371 is fixedly connected to the top of the sedimentation tank 31, and the side of the adjusting baffle 374 is in contact with the inner wall of the sedimentation tank 31.

[0026] The collecting device 33 includes a collecting tank shell 331 , a collecting box 332 is slidably connected to the inner wall of the collecting tank shell 331 , a collecting box handle 333 is fixedly connected to the inner wall of the collecting box 332 , and the top of the collecting tank shell 331 is flush with the top of the sedimentation tank 31 .

[0027] During use, water flows into the sedimentation tank 31 from the water inlet pipe 34, the separation tank 32 and the collecting device 33 are connected, the liquid level inside the collecting device 33 is flush with the liquid level inside the water inlet pipe 34, and the water flows into the sedimentation tank 31 from the water inlet pipe 34 and flows out from the water outlet pipe 36. In the process of the water flowing from the water inlet pipe 34 to the water outlet pipe 36, the water flow rate is reduced by the action of the inner wall of the sedimentation tank 31, and the silt and other components in the water settle in the sedimentation tank 31 under the action of inertia.

When adjusting the flow rate, the handle dial 373 is manually rotated, and the rotation of the handle dial 373 drives the adjusting screw 372 to rotate. The adjusting screw 372 rotates through the thread to achieve the up and down movement of the adjusting bracket 371.

Water enters the reflux pipe 54 along the reflux funnel 53 and enters the dephosphorization device 6 for dephosphorization. Automatic collection of large particles is achieved, and the separated water is refluxed at the same time, thereby ensuring the dephosphorization effect.

[0033] See also Figure 1-Figure 18 On the basis of Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4, the present invention provides a technical solution: the dephosphorization device 6 includes a filter box 61, a slide bar 62 is fixedly connected to the inner wall of the filter box 61, a dephosphorization box 63 is slidably connected to the inner wall of the filter box 61, a slide groove 64 adapted to the slide bar 62 is opened on the side of the dephosphorization box 63, an inner box handle 65 is fixedly connected to the inner wall of the dephosphorization box 63, a filter screen frame 66 is fixedly connected to both sides of the dephosphorization box 63, a metal mesh 67 is fixedly connected to the inner wall of the filter screen frame 66, a guide block 68 is fixedly connected to the bottom of the inner wall of the filter box 61, the side of the filter box 61 is connected to the return pipe 54, and the top of the filter box 61 is fixedly connected to the bottom of the water inlet box 41.

[0034] During use, the water flows through the water inlet box 41 and then enters the filter box 61. The water flows through the filter box 61 and then enters the dephosphorization box 63. The dephosphorization box 63 is filled with hematite. The water flows through the hematite in the dephosphorization box 63 to remove phosphorus. The free phosphorus element is adsorbed by the hematite to purify the water body. In the purification of the front device, the impurity content in the water body is relatively low, which is conducive to the hematite to fully remove phosphorus from the water body. At the same time, after the hematite has completed the dephosphorization effect, the dephosphorization box 63 of the hematite of the device can be removed as a whole through the inner box handle 65, which is conducive to the rapid replacement of hematite. At the same time, the setting of the guide block 68 is conducive to the water entering the dephosphorization box 63, reducing the accumulation of water impurities at the bottom of the filter box 61. The dephosphorization of the water body is achieved. At the same time, the process of hematite dephosphorization is a physical process, which does not produce new impurities in the water body. At the same time, the hematite is cheap and easy to obtain. At the same time, it can be used again after high-temperature treatment after use.
