Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a system and method for rapidly treating metal pollution in a river. Background Art

[0002] River pollutants include organic matter, nitrogen and phosphorus compounds, heavy metals, and pathogens, which can lead to eutrophication of water bodies and decline in biodiversity.

[0003] Heavy metal pollution is characterized by its persistence, bioaccumulation and toxicity in the environment. These characteristics make it difficult for heavy metals to degrade once they enter the water body, and they may accumulate through the food chain, ultimately affecting human health. For example, long-term drinking of water containing heavy metals may lead to health problems such as nervous system damage and abnormal liver and kidney function. Therefore, a system for quickly treating metal pollution in rivers is urgently needed.

[0004] The patent with the publication number CN215326985U discloses a fully automatic dosing device for river channel management agents, including a bridge body and a medicine box, the bridge body is composed of a bridge foundation, a bridge pier and a bridge deck, the medicine box is installed on the lower end face of the bridge deck, a piston is slidably connected in the medicine box, a rotating shaft is arranged at the center of the piston in a top view, a flow rate detection paddle is arranged at the lower end of the rotating shaft, a dosing pipe and a dosing pipe are arranged at the side end of the medicine box, a nozzle is arranged at the lower end of the dosing pipe, a dosing hopper is arranged at the upper end of the dosing pipe, a dosing indicator rod is slidably connected to the upper end face of the medicine box, a first axial hole is arranged on the upper and lower end faces of the medicine box, a second axial hole is arranged on the bridge deck, and the rotating shaft passes through the first axial hole and the second axial hole and is rotatably connected to the medicine box and the bridge deck. The utility model controls the dosing amount of the medicine by the cooperation of the flow rate detection paddle, the rotating shaft and the piston, ensures the uniformity of the dosing, and thus greatly improves the river channel management effect.

[0005] However, the above device is only suitable for situations where the water flow rate is relatively high. When the water flow rate is not sufficient to drive the paddle blades to rotate quickly, so that the piston cannot be fully squeezed upward or cannot be squeezed at all, it will result in too little agent being added, greatly reducing the treatment effect on the river channel. Summary of the invention

[0006] In view of the above problems, the present invention provides a system and method for rapidly treating metal pollution in rivers.

[0007] The technical solution of the present invention is: a system for rapidly treating metal pollution in a river, comprising an automatic agent spraying assembly mounted on the upper end of a water source, an agent mixing assembly and an air distribution assembly connected to the automatic agent spraying assembly;

[0008] The automatic medicine spraying assembly includes a mounting main frame perpendicular to the water flow direction of the water source, a temporary storage box arranged at the upper end of the mounting main frame, a plurality of automatic medicine adding cylinders arranged at the lower end of the mounting main frame and connected to the temporary storage box through a connecting branch pipe, and an automatic medicine adding unit arranged in each of the automatic medicine adding cylinders;

[0011] The gas distribution assembly includes an air storage tank connected to the temporary storage box through a connecting pipe, a first air compressor connected to the air storage tank, and a pressure gauge arranged on the air storage tank.

[0012] Furthermore, a mixing and stirring unit is provided in the temporary storage box, and the mixing and stirring unit includes a horizontal rotating cylinder connected to the inner wall of the temporary storage box by hollow connecting cylinders on the left and right sides respectively, a plurality of sleeve rings evenly distributed on the outer wall of the horizontal rotating cylinder from left to right, a plurality of arc-shaped stirring blocks inclined in the same direction and circumferentially arranged on the outer wall of the sleeve ring, a first rotating motor connected to one of the hollow connecting cylinders by a rotating shaft, and a second air compressor connected to the other hollow connecting cylinder by a connecting pipe, a spiral air duct is penetrated by the arc-shaped stirring block, and the hollow connecting cylinder and the sleeve ring as well as the spiral air duct and the interior of the sleeve ring are interconnected.

[0013] Description: In order to prevent the high-density components in the medicine in the temporary storage box from settling to the bottom and ensure the stability and consistency of the overall properties of the medicine, it is stirred by a mixing and stirring unit. At the same time, air is introduced into the medicine through the second air compressor. The introduction of air helps to break the stratification of the medicine, increase the mixing effect, and make the medicine more uniform. When the mixing and stirring unit is in use, the horizontal rotating cylinder, the sleeve ring and the arc-shaped stirring block are driven to rotate synchronously by the first rotating motor, and the medicine in the temporary storage box is stirred. At the same time, the external air is introduced into the entire horizontal rotating cylinder through the hollow connecting cylinder connected to it through the second air compressor, and enters the corresponding arc-shaped stirring block through each sleeve ring. Since each arc-shaped stirring block is provided with a spiral airway, the ventilation in the arc-shaped stirring block is ejected in a swirling manner through the spiral airway and mixed with the medicine, which can produce smaller and more uniform bubbles, increase the gas-liquid contact area, and at the same time cooperate with the rotation of the arc-shaped stirring block itself to increase the mixing effect and make the medicine more uniform.

[0014] Furthermore, a constant temperature heating ring is provided on the outer wall of the horizontal rotating cylinder and between two adjacent sleeve rings, each inner wall of the temporary storage box is provided with a constant temperature heating plate, and a plurality of stirring teeth are evenly provided on the side wall of the arc-shaped stirring block.

[0015] Description: When stirring the reagent in the temporary storage box, the inside of the reagent is evenly heated by the constant temperature heating ring and the constant temperature heating plate. At the same time, the movement of the swirl bubbles can enhance the heat convection inside the reagent, increase the temperature of the reagent, and increase the solubility of the solute in the reagent, thereby reducing the possibility of crystallization, avoiding the blockage of the spray holes on the hollow spray column, and improving the overall operation reliability of the system. The stirring teeth on the side wall of the arc-shaped stirring block further improve the stirring uniformity.

[0016] Furthermore, an air distribution plate is provided in the temporary storage box and at the connection with the air storage tank, and a plurality of air distribution holes are evenly arranged on the air distribution plate.

[0017] Note: When the gas in the gas storage tank is passed into the temporary storage box, the gas is evenly distributed in the temporary storage box in the form of small bubbles through the gas distribution holes on the gas distribution plate, thereby increasing the contact area between the gas and the reagent.

[0018] Furthermore, the air distribution holes and the openings of the spiral air passages are both provided with micro filter residue nets, and the micro filter residue nets are made of elastic material.

[0019] Description: The micro-filter residue net is used to block solid impurities in the reagent from entering the air holes and spiral air ducts to avoid blockage of the air holes and spiral air ducts. The micro-filter residue net is set as an elastic structure to buffer the impact of water flow on itself when stirring the reagent, thereby improving reliability.

[0020] Furthermore, the medicine dispensing box includes a main box body with a cover plate hinged on the upper end, a suspension frame arranged in the main box body and provided with a plurality of through holes on the upper end, a plurality of medicine dispensing inner cylinders located in the main box body and connected one-to-one with the through holes at the upper ends, and a mixing and stirring element arranged in each medicine dispensing inner cylinder. The side wall of the medicine dispensing inner cylinder passes through a liquid outlet pipe to the outside, a flow meter is provided on the liquid outlet pipe, and a sub-cover plate is provided on the cover plate at the position directly above each of the through holes.

[0021] Description: Open the sub-cover, add the original medicine required for preparing the medicine into each medicine dispensing inner cylinder, and stir it evenly through the mixing and stirring piece. When it is necessary to add medicine to the water source, the prepared medicine in the medicine dispensing inner cylinder will flow out through the liquid outlet pipe, and after filtering impurities through the medicine filter, it will flow into the temporary storage box. Through several medicine dispensing inner cylinders, the same medicine can be prepared in batches, and different types of medicines can be prepared at the same time, which significantly improves the efficiency of medicine preparation. It is particularly suitable for water sources that require a large amount or a variety of medicines.

[0022] Furthermore, the mixing and stirring element includes a vertical rotating rod whose upper end is located in the medicine dispensing inner cylinder and whose bottom end passes through the medicine dispensing inner cylinder and the main box body and extends to the outside, a plurality of rotating gears arranged at the bottom end of the main box body and whose centers are connected one-to-one with each of the vertical rotating rods, a second rotating motor connected to the center of one of the rotating gears, a plurality of connecting plates distributed circumferentially along the bottom end of the vertical rotating rod, a plurality of spiral heating tubes and a plurality of spiral refrigeration tubes connected to the connecting plates at the bottom ends and distributed vertically, the plurality of spiral heating tubes and the plurality of spiral refrigeration tubes are staggered, and two adjacent rotating gears are meshed with each other.

[0023] Description: When the mixing and stirring element is used to stir the original medicine required for adding and preparing the medicine, the second rotating motor is started, and the corresponding rotating gear is driven to rotate by the second rotating motor, and the other rotating gears meshing with it also rotate synchronously. At this time, the vertical rotating rod connected to each rotating gear and located in the medicine dispensing inner cylinder rotates synchronously, and the spiral heating tube and spiral refrigeration tube installed on the outer wall of each vertical rotating rod are stirred. While achieving the stirring effect, according to the temperature of the medicine in each medicine dispensing inner cylinder, whether to turn on the spiral heating tube and the spiral refrigeration tube is selected. When the external ambient temperature causes the temperature of the medicine to be too low, the spiral heating tube is used to heat the medicine to prevent the medicine from freezing and affecting normal use. At the same time, when the external ambient temperature causes the temperature of the medicine to be too high, the spiral refrigeration tube is used to cool the medicine to prevent the medicine from being deteriorating due to excessive temperature.

[0024] Furthermore, a heat-insulating layer is provided on the inner wall of the main box, and a temperature sensor is provided in each medicine dispensing inner cylinder.

[0025] Description: The insulation layer can reduce the excessive temperature change of the medicine in the medicine dispensing inner cylinder and affect the treatment effect. The temperature of the medicine in the medicine dispensing inner cylinder is detected in real time by the temperature sensor to improve the degree of intelligence.

[0026] The present invention also discloses a method for rapidly treating metal pollution in a river. Based on the above-mentioned system for rapidly treating metal pollution in a river, the method comprises the following steps:

[0027] S1. Install the main frame on both sides of the upstream of the water source to be repaired, so that each vertical connecting rod and the hollow spray column extend into the water body, and the medicine in the medicine preparation box is extracted by the medicine adding pump, and after the impurities are filtered out by the medicine filter, it flows into the temporary storage box. At the same time, the gas is continuously filled into the gas storage tank through the first air compressor, and the pressure is monitored in real time through the pressure gauge, and the gas from the gas storage tank is filled into the temporary storage box;

[0028] S2, after the medicine and gas charged in step S1 are mixed in the temporary storage box, they flow into the automatic medicine adding cylinder through each connecting branch pipe. At this time, under the impact of the water flow, the stirring blade at the bottom end of each vertical connecting rod rotates, and the rotating piston is driven to rotate through the vertical connecting rod, squeezing the medicine in the automatic medicine adding cylinder, so that the medicine falls into the hollow spray column, and is evenly sprayed in the water body of each depth through each spray hole on the hollow spray column, thereby repairing the water body;

[0029] S3. When the water flow at the water source is static, the first electromagnetic suction cup and the second electromagnetic suction cup are energized to make them adsorbed and fixed. At this time, the micro-drive motor is started to drive the rotating piston to rotate. Since the upper end of the automatic drug adding cartridge is connected to the second electromagnetic suction cup through the telescopic rod, the rotating piston will move downward and squeeze the medicine at its bottom while rotating, so that the medicine falls into the hollow spray column and is evenly sprayed in water bodies of various depths through the various spray holes on the hollow spray column, thereby repairing the water body.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] When the system for rapidly treating metal pollution in rivers of the present invention is used, the same kind of agents are configured in batches or various kinds of agents are configured simultaneously through the agent preparation component, the external air is collected through the air distribution component, and then, the configured agents and the introduced air are evenly mixed through the temporary storage box, and then each automatic drug adding cylinder is evenly sprayed into the water body of the water source through the automatic drug adding unit. At the same time, the automatic drug adding unit can also automatically squeeze the agents and spray them into the polluted water at various depths under the action of the water flow, so that the agents can be evenly mixed with the polluted water, and there will be no situation where there are drugs in some parts but no drugs in most parts, thereby improving the treatment effect. At the same time, when the water flow in the water source is in a static state, the automatic drug adding unit can also squeeze the agents and automatically spray them by means of a micro-drive motor, thereby reducing the dependence on manual labor, and can automatically adjust the agent spraying method according to the water flow state, whether it is water flow impact or static state, it can ensure the effective distribution of the agents, thereby improving the flexibility and adaptability of the system.

[0053] S2, install the main frame 10 on both sides of the upstream of the water source to be repaired, so that each vertical connecting rod 132 and the hollow spray column 134 extend into the water body, and the medicine in the medicine dispensing box 20 is extracted by the medicine pump 21, and after the impurities are filtered by the medicine filter 22, it flows into the temporary storage box 11, and at the same time, the gas is continuously filled into the gas storage tank 30 through the first air compressor 31, and the pressure is monitored in real time by the pressure gauge 32, and the gas in the gas storage tank 30 is filled into the temporary storage box 11;

[0054] S3, after the medicine and gas charged in step S1 are mixed in the temporary storage box 11, they flow into the automatic medicine adding cylinder 12 through each connecting branch pipe 120. At this time, under the impact of the water flow, the stirring blade 133 at the bottom end of each vertical connecting rod 132 rotates, and the rotating piston 131 is driven to rotate through the vertical connecting rod 132, squeezing the medicine in the automatic medicine adding cylinder 12, so that the medicine falls into the hollow spray column 134, and is evenly sprayed in the water body of various depths through each spray hole 138 on the hollow spray column 134, thereby repairing the water body;

When the medicine in the temporary storage box 11 is stirred, the inside of the medicine is evenly heated by the constant temperature heating ring 157 and the constant temperature heating plate 158. At the same time, the movement of the swirl bubbles can enhance the heat convection inside the medicine, increase the temperature of the medicine, and increase the solubility of the solute in the medicine, thereby reducing the possibility of crystallization, avoiding the blockage of the spray hole 138 on the hollow spray column 134, and improving the overall operation reliability of the system. The stirring uniformity is further improved by the stirring teeth 1531 on the side wall of the arc-shaped stirring block 153. Among them, the constant temperature heating ring 157 and the constant temperature heating plate 158 are both based on the existing technology;

[0058] like Figure 5 As shown, a gas distribution plate 33 is provided in the temporary storage box 11 and at the connection with the gas storage tank 30, and 20 gas distribution holes 330 are evenly provided on the gas distribution plate 33. When the gas in the gas storage tank 30 is passed into the temporary storage box 11, the gas is evenly distributed in the temporary storage box in the form of fine bubbles through the gas distribution holes 330 on the gas distribution plate 33, thereby increasing the contact area between the gas and the medicine, wherein the gas distribution plate 33 adopts the existing technology;

[0059] The openings of the air distribution holes 330 and the spiral air duct 1530 are both provided with a micro-filter residue net 16, which is made of elastic material. The micro-filter residue net 16 blocks solid impurities in the agent from entering the air distribution holes 330 and the spiral air duct 1530, thereby avoiding blockage of the air distribution holes 330 and the spiral air duct 1530. The micro-filter residue net 16 is set as an elastic structure, which can buffer the impact force of water flow on itself when stirring the agent, thereby improving reliability.

[0060] Embodiment 5: This embodiment is different from Embodiment 3 in that: there are 6 sleeve rings 152 and each sleeve ring 152 has 8 arc-shaped stirring blocks 153 on its outer wall;

[0061] Fourteen stirring teeth 1531 are evenly arranged on the side wall of the arc-shaped stirring block 153 .

[0062] Embodiment 6: The difference between this embodiment and embodiment 3 is that: in step S3, when the medicine and gas filled in step S1 are mixed in the temporary storage box 11, the horizontal rotating cylinder 151, the sleeve ring 152 and the arc-shaped stirring block 153 are driven by the first rotating motor 154 to rotate synchronously, and the medicine in the temporary storage box 11 is stirred. At the same time, the external air is introduced into the entire horizontal rotating cylinder 151 through the hollow connecting cylinder 150 connected thereto by the second air compressor 155, and enters the corresponding arc-shaped stirring block 153 through each sleeve ring 152. Since each arc-shaped stirring block 153 is provided with a spiral air duct 1530, the ventilation in the arc-shaped stirring block 153 is ejected in a swirl manner through the spiral air duct 1530 and mixed with the medicine. During the stirring process, the inside of the medicine is evenly heated by the constant temperature heating ring 157 and the constant temperature heating plate 158.
