Description

Technical Field

[0001] The utility model belongs to the field of water purification equipment, in particular to a basin water purification device. Background Art

[0002] A water purification device is a device or system used to treat pollutants in water bodies. Its main purpose is to purify and improve the quality of water bodies in the basin to meet people's demand for water resources and protect the environment. It is generally suitable for the treatment and restoration of polluted water environments, such as rivers, lakes, wetlands, etc., or for extracting and purifying water from rivers, lakes or groundwater sources. Pollutants are removed through purification devices to restore the balance and health of the water ecosystem. Existing water purification devices only perform preliminary filtration on water from rivers, lakes or groundwater sources, which can easily remove larger suspended matter, impurities and solids. This simple operation does not require complex technology or operation, and is easy to maintain and manage. At the same time, compared with complex multi-stage treatment units or advanced technologies, the cost of basin water purification devices that only use preliminary filtration components is low. The manufacturing, installation and maintenance costs of preliminary filtration components are relatively low, which is suitable for projects with limited budgets or resource-scarce areas. However, in actual use, basin water purification devices have limited purification effects on fine particles, chemicals and soluble pollutants. This is because there is a lack of multi-stage treatment units. The lack of multi-stage treatment units will not only lead to the above problems, but also may result in a small amount of water that can be treated. If a large amount of water needs to be treated, the number of filtration equipment needs to be increased, which increases the investment and operation and maintenance costs. First, a variety of treatment units can be set up to specifically treat different types of pollutants, while the preliminary filtration components mainly remove suspended matter and solid particles, while other treatment units can remove and degrade organic matter, chemicals and microorganisms in a targeted manner. Such comprehensive treatment can more comprehensively remove a variety of pollutants in the water body and improve the effect of water purification. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

The motor 120 is installed at the center of the upper surface of the sedimentation tank 100. The output shaft of the motor is connected to the rotating shaft 121 through a coupling. A plurality of stirring rods 122 are evenly installed on the outer surface of the rotating shaft 121. A liquid level sensor 101 is arranged on the inner wall below the place where the water inlet pipe 110 communicates with the sedimentation tank 100.

[0026] The feed tank 130 is connected to the inside of the sedimentation tank 100, and a solenoid valve is provided at the connection between the feed tank 130 and the sedimentation tank 100.

[0029] When in use, the user first prepares an external pump, then adds flocculant into the feeding tank 130, and then pumps the water source to be purified into the sedimentation tank 100 through the water inlet pipe 110 and the pump. The water source to be purified must not be higher than the position of the liquid level sensor 101. At the same time, the liquid level sensor 101 can also remind the user of the position of the water source (the liquid level sensor 101 is a prior art, and its model can be selected from existing products on the market. Its structure and working principle are not described here). Then, the solenoid valve connecting the feeding tank 130 and the sedimentation tank 100 is opened to add the flocculant into the sedimentation tank 100, and then the motor 120 is started synchronously. The output shaft of the motor 120 rotates and then drives the rotating shaft 121 and the stirring rod 122 to rotate inside the sedimentation tank 100, so that the flocculant can be well mixed with the water source to be purified. After the mixing is completed, the user turns off the motor 120, and then selects the required standing time according to the actual situation. When the standing time is completed, the mud in the water The sand and the generated flocculants will settle to the bottom of the sedimentation tank 100. Then the user can turn on the water pump 1 inside the pump assembly 210. Then the water pump 1 works to pump water from the middle position inside the sedimentation tank 100 into the filter tank 200 through the pipeline. When the pump assembly 210 is working, the user can open the solenoid valve on the outer surface of the discharge pipe 140 to pump the sediment at the bottom of the sedimentation tank 100, and then collect it for subsequent treatment (such as drying, dehydration and anaerobic digestion of the sediment) to avoid discharging it to pollute the environment. Then the water source pumped into the filter tank 200 will be filtered through the quartz sand layer 220, the gravel layer 230 and the activated carbon layer 240, which will help to further filter and remove various pollutants in the water and provide higher quality purified water. Then the water pump 2 inside the pump assembly 2 350 is started to pump the filtered water inside the filter tank 200 into the biological purification tank 300 through the pipeline for the next step of treatment.

[0030] See also Figure 1As an embodiment of the utility model: the pumping assembly 2 350 includes a water pump 2 and a pipeline, the water pump 2 is installed between the two pipelines, the two pipelines are respectively connected to the filter pool 200 and the biological purification pool 300, and a solenoid valve is provided on the outer surface of the left pipeline. A plurality of biological fillers 310 are evenly installed in the biological purification pool 300 at staggered intervals, and the material of the biological filler 310 is perlite;

[0031] The aeration assembly includes an aeration pump 320, an aeration pipe 330 and an aeration nozzle 340. The aeration pump 320 is installed on the lower surface of the biological purification tank 300. The aeration port of the aeration pump 320 is connected to the aeration pipe 330 through a pipeline penetrating the lower surface of the biological purification tank 300. A sealing ring is provided at the connection between the pipeline and the biological purification tank 300. The aeration pipe 330 is provided at the bottom of the biological purification tank 300.

[0032] A plurality of aeration nozzles 340 are evenly installed on the outer surface of the aeration pipe 330, and the aeration nozzles 340 are connected to the inside of the aeration pipe 330. The pumping assembly 3 410 includes a water pump 3 and a pipeline. The water pump 3 is installed between the two pipelines. The end of the left pipeline away from the water pump 3 is arranged at the lower half of the inside of the biological purification tank 300, and the end of the right pipeline away from the water pump 3 is arranged at the upper part of the inside of the disinfection tank 400.

[0033] A secondary filter layer 420 is installed in the upper part of the interior of the disinfection tank 400. The material of the secondary filter layer 420 is activated carbon particles. A sedimentation filter plate 450 is arranged below the secondary filter layer 420. A chlorine generator 430 is arranged on the right side of the outer surface of the disinfection tank 400. The chlorine generating end of the chlorine generator 430 is arranged inside the disinfection tank 400 through a pipeline.

A screw 462 is installed on the outer surface of the rotating shaft 461. A waterproof sealing ring is provided at the through connection between the motor 460 and the disinfection tank 400, and a solenoid valve is installed on the outer surface of the water outlet pipe 440 on the lower surface of the disinfection tank 400;

At this time, the user can open the sealed hinged door panel to replace or clean these materials.

[0036] When the water source enters the biological purification pool 300 through the pumping component 2 350, the user can start the aeration pump 320 at this time. The aeration pump 320 works and then injects air into the aeration pipe 330 through the pipeline, and then the aeration nozzle 340 on the outer surface of the aeration pipe 330 sprays oxygen, and then the biological purification pool 300 is filled with oxygen, which helps the microorganisms and the water source to react quickly. At the same time, the biological filler 310 inside it provides a large amount of load surface, which provides sufficient attachment area for the growth of microorganisms, and increases the ability of the biological purification pool 300 to treat wastewater. Then, when the biological purification pool 300 has completed the treatment of the water source, the user can start the pumping component 3 410. The water pump 3 inside the pumping component 3 410 works to draw the water source inside the biological purification pool 300 into the disinfection pool 400 through the pipeline. Then, because the water in the biological purification pool 300 may contain some tiny suspended matter and particulate matter after the degradation of the biological filter material, the secondary filtration layer 4 inside the disinfection pool 400 is at this time. 20 can be combined with the sedimentation filter plate 450 to achieve the effect of secondary filtration, further remove impurities and suspended matter in the water, and improve the clarity and transparency of the water. Then, when the water source is gathered inside the disinfection tank 400, the user can turn on the chlorine generator 430, and then the chlorine generator 430 works to produce chlorine dioxide (the user can choose the concentration of chlorine generated according to the actual situation, and the chlorine generator 430 can use the market product model. The chlorine generation concentration and quantity of chlorine in the chlorine generator 430 of different products will be different, so as to avoid secondary damage to the water body), and then the water source inside the disinfection tank 400 is filled with chlorine dioxide. Then, the user can start the motor 2 460 at this time, and the output shaft of the motor 2 460 rotates to drive the rotating shaft 2 461 and the auger 462 to rotate inside the disinfection tank 400, so that the chlorine dioxide is more fully mixed with the water body to achieve a better disinfection effect. Then, after the disinfection is completed, the user opens the solenoid valve on the outer surface of the water outlet pipe 440 to discharge the treated water body.
