Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filtering devices, more particularly to a flexible calling water body filtering device based on a combined action mechanism. BACKGROUND

[0002] The flexible calling water body filtering device based on a combined action mechanism is a technical innovation direction in the field of water treatment in recent years. The device realizes efficient purification through the synergistic effect of multiple filtering units. A typical design includes the cross-integrated structure of a primary coarse filtering device and a secondary fine filtering device. The primary filtering unit uses quartz sand, filter screen and other media to intercept large particle suspended solids. The secondary unit uses activated carbon, ceramic ring and other materials for deep adsorption and biochemical treatment. Some devices also integrate a rotating screen and membrane separation technology to realize solid-liquid separation and molecular-level pollutant interception using centrifugal force and selective permeable membranes. A water pressure difference sensor is used to monitor the pressure on both sides of the filtering unit in real time. When the pressure difference reaches the threshold of 0.07-0.15 MPa, the backwashing program is automatically triggered. For example, a utility model patent uses a water pressure gauge and an electromagnetic valve linkage system to manually or automatically switch the washing mode. The modular design supports flexible addition or subtraction of the number of secondary filtering units according to the processing flow, which adapts to different scene requirements such as industrial wastewater treatment and urban drainage pipe network.

[0003] A water body filtering device is disclosed in Chinese Patent No. CN106064003A, which includes an outer shell and an inner shell of a water tank. The outer shell is provided with a water inlet pipe on one side above. The inner shell is fixed inside the outer shell, and the upper end of the inner shell is provided with an end cover to prevent dust from entering. The side of the inner shell is provided with a plurality of filter devices. A water outlet pipe is provided below the side of the inner shell and penetrates the inner shell and the outer shell. The water outlet pipe is connected to external water equipment. The present application filters the water flowing into the outer shell through the multiple filters of the inner shell, removes salt, desalts brackish water quality, decolorizes sugar solution, and treats radioactive wastewater. The water outlet of the inner shell provides good quality water for residents, reduces diseases, and enhances people's health.

[0004] Currently, the existing multi-stage filtering device usually works all the filtering cores at the same time, regardless of the impurity content of the water quality, resulting in energy waste. In addition, during the filtering process, the filter plate needs to be cleaned and replaced regularly by manual operation, resulting in high downtime and maintenance cost. SUMMARY

The first motor 601 is an existing structure, and the specific structure and connection method of the first motor 601 will not be described in detail in this embodiment.

[0019] Reference Figures 1-3 and Figure 5The water quality measuring component 2 includes a container 201, which is fixedly connected to the filter tube 101. A water quality sensor 202 is fixedly connected to the bottom of the container 201. A drain hole 203 extends through the bottom of the container 201. A moving groove 204 is provided inside the drain hole 203. The cross-sectional projection of the drain hole 203 is projected into the cross-sectional projection of the moving groove 204. A sealing plate 205 is slidably connected inside the moving groove 204. The sealing plate 205 can open or close the drain hole 203 during the sliding process. A first hydraulic cylinder 206 is connected between the sealing plate 205 and the side wall of the moving groove 204. A camera 207 is fixedly connected to the bottom of the container 201.

[0020] In this embodiment, it should be specifically explained that: the sewage to be filtered is poured into the holding basin 201, and then the water quality sensor 202 starts to measure the water quality. After the sewage quality test is completed, the first oil cylinder 206 is started. The first oil cylinder 206 drives the sealing plate 205, and the drain hole 203 gradually opens, and the sewage begins to be initially filtered.

[0021] Reference Figure 2 , Figure 3 and Figure 5 The filter assembly 9 includes a third cylinder 901. The cylinder body of the third cylinder 901 is fixedly connected to the sealing groove 108. The piston head of the third cylinder 901 is fixedly connected to a sealing plate 902. A movable filter plate 903 is provided at the bottom of the sealing plate 902. The movable filter plate 903 prevents sewage from spreading outward from the through hole 107. The housing of the second motor 904 is fixedly connected to the side wall of the protruding pipe 102. The shaft of the second motor 904 is fixedly connected to a screw 905. The screw 905 is screw-driven to the movable filter plate 903. A guide rod 907 is slidably connected to one side of the movable filter plate 903. A bracket 906 is rotatably connected to both ends of the screw 905 and the guide rod 907. The bracket 906 is fixedly connected to the bottom wall of the protruding pipe 102.

[0022] In this embodiment, it should be specifically noted that the movable filter plate 903 and the screw 905 can be made of stainless steel, engineering plastic, or have a surface coating, which has good corrosion resistance. When the camera 207 observes that too many impurities have accumulated on the movable filter plate 903 and the filtration speed has slowed down significantly, the first oil cylinder 206 is activated. The first oil cylinder 206 drives the sealing plate 205 to close the drain hole 203. After the sewage on the movable filter plate 903 is filtered, the third oil cylinder 901 is activated, which drives the sealing plate 902 to rise. Then the second motor 904 is activated, which drives the screw 905 to rotate, moving the unfiltered part of the movable filter plate 903 to the bottom of the drain hole 203.

[0023] Reference Figure 1 , Figure 3 and Figure 4The spray assembly 3 includes a movable sealing column 301, which is located on both sides of the movement trajectory of the movable filter plate 903. The outer side of the movable sealing column 301 is slidably sealed with a delivery tube 302. The other end of the delivery tube 302 is fixedly connected to a nozzle 303. The nozzle 303 passes through the spray hole 106 and is located directly above the movable filter plate 903. The outlet of the nozzle 303 is a hydrophobic outlet, and its hydrophobic structure is configured to preferentially allow the liquid medium to pass through and inhibit the gas from passing through. A washing solvent tank 304 passes through the top of the delivery tube 302.

[0024] In this embodiment, it should be specifically explained that: the moving filter plate 903 of the filtration section drives the moving sealing column 301 of the corresponding section. The moving sealing column 301 compresses the detergent inside the infusion tube 302 of the corresponding section and flows it to the nozzle 303. The nozzle 303 sprays the detergent outward onto the surface of the moving filter plate 903. While the moving filter plate 903 is moving, the moving filter plate 903 of the unfiltered section drives the corresponding moving sealing column 301 to move towards the center. At this time, a negative pressure is generated inside the infusion tube 302 of the corresponding section, which causes the infusion port of the washing solvent tank 304 to be opened, and the detergent inside the washing solvent tank 304 enters the infusion tube 302 of the corresponding section.

[0025] Reference Figures 2-4 and Figure 7 The cleaning brush assembly 4 includes a guide rod 401. The two ends of the guide rod 401 are fixedly connected to the inner wall of the protruding tube 102 and the outer wall of the filter tube 101, respectively. The guide rod 401 is slidably connected to the slider 402 through the guide hole 403. Several mounting grooves 404 are fixedly connected to the bottom of the slider 402. Several bristles 405 are fixedly connected inside the mounting grooves 404. A second hydraulic cylinder 406 is fixedly connected between the slider 402 and the inner wall of the protruding tube 102.

[0026] In this embodiment, it should be specifically noted that: the guide rod 401 and the slider 402 can be made of stainless steel, engineering plastic or surface coating, and have good corrosion resistance. When the moving filter plate 903 is to be cleaned, the second oil cylinder 406 at the corresponding position is activated. The second oil cylinder 406 drives the brush bristles 405 to rub back and forth on the surface of the moving filter plate 903 to clean the surface of the moving filter plate 903.

[0027] Reference Figure 3 and Figure 6 The ultraviolet sterilization component 7 includes a reaction cylinder 701, which has a quartz cavity 702 and a stainless steel cavity 703. The stainless steel cavity 703 is equipped with an ultraviolet lamp 704. The bottom of the quartz cavity 702 is provided with a second clearance hole 705 and a sealing hole 706.

[0028] In this embodiment, it should be specifically explained that: water containing microorganisms enters the quartz cavity 702. At this time, the ultraviolet lamp 704 has been turned on, and water continuously flows into the interior of the quartz cavity 702. The ultraviolet lamp 704 sterilizes the accumulated water.

[0029] Reference Figure 3 and Figure 6 The pressure drainage assembly 8 includes a pressure-bearing column 801, which is slidably and sealingly connected to the second clearance hole 705. A movable switch 802 extends out from the side of the pressure-bearing column 801. The movable switch 802 is L-shaped. A spring 803 is connected between the pressure-bearing column 801 and the support layer 105. A telescopic tube 804 is sleeved on the outside of the spring 803. The two ends of the telescopic tube 804 are fixedly connected to the bottom of the pressure-bearing column 801 and the support layer 105, respectively. A telescopic cylinder 805 is fixedly connected to the bottom of the quartz cavity 702. A sealing hole is provided at the bottom of the telescopic cylinder 805. The sealing hole is sealed and connected to the vertical part of the movable switch 802. A drain pipe 806 is connected through the side wall of the telescopic cylinder 805.

[0030] In this embodiment, it should be specifically explained that as the water inside the quartz cavity 702 increases, the pressure column 801 is lowered, and the drain pipe 806 also lowers until the water inside the quartz cavity 702, after being disinfected, enters the telescopic cylinder 805 through the sealing hole 706 and is collected after flowing out through the drain pipe 806.

[0031] The specific steps are as follows: First, the wastewater to be filtered is poured into the container 201. Then, the water quality sensor 202 begins to measure the water quality. When the water quality is good, the first motor 601 is activated. The first motor 601 drives the gear 602 to rotate, and the gear 602 drives the rack 603 to move. The rack 603 drives the ion exchange tank 604 from inside the filter tube 101 to outside the filter tube 101. At the same time, the ultraviolet lamp 704 is turned off. When high water hardness is detected, the first motor 601 is activated again. The first motor 601 reverses and drives the ion exchange tank 604 to move directly below the activated carbon filter box 5. This initiates the "ion exchange tank" process. The process softens the wastewater. When a risk of microbial contamination is detected, the ultraviolet lamp 704 is turned on for ultraviolet sterilization. After the wastewater quality test is completed, the first hydraulic cylinder 206 is activated, which drives the sealing plate 205, gradually opening the drain hole 203. The wastewater falls freely onto the moving filter plate 903, where larger particles and suspended solids are filtered out. The water then enters the activated carbon filter box 5, where the activated carbon adsorbs organic pollutants and odors. Simultaneously, the residual chlorine sensor inside the ion exchange tank 604 senses whether the activated carbon has lost its chlorine content after adsorption. If the activated carbon filter fails, the activated carbon inside the activated carbon filter box 5 is replaced. When harder wastewater subsequently enters the ion exchange tank 604, the ion exchange resin firmly "captures" calcium and magnesium ions in the water and releases an equal amount of harmless sodium ions into the water. When the pressure sensor inside the ion exchange tank 604 indicates an increase in inlet water pressure, the outlet valve below the activated carbon filter box 5 is immediately closed, and the first motor 601 is started to move the ion exchange tank 604 from inside the filter tube 101 to outside the filter tube 101. At the same time, an external cleaning device is connected, and after backwashing, regeneration, and forward washing, the resin is cleaned. After cleaning, the first motor 601 is started, which reverses and moves the ion exchange tank 604 to directly below the activated carbon filter box 5. After the water passes through the ion exchange tank 604, the water containing microorganisms enters the quartz cavity 702. At this time, the ultraviolet lamp 704 is turned on, and water continuously flows into the quartz cavity 702. The ultraviolet lamp 704 sterilizes the accumulated water. As the water increases, it compresses the pressure column 801 and lowers it. The drain pipe 806 also lowers until the water inside the quartz cavity 702, after being sterilized, enters the telescopic cylinder 805 through the sealing hole 706 and is collected after flowing out through the drain pipe 806. When camera 207 observes excessive accumulation of impurities on the movable filter plate 903 and the pressure difference value of the pressure sensor above and below the movable filter plate 903 reaches the threshold, the first hydraulic cylinder 206 is activated. The first hydraulic cylinder 206 drives the sealing plate 205 to close the drain hole 203. After the sewage on the movable filter plate 903 is filtered, the third hydraulic cylinder 901 is activated, driving the sealing plate 902 to rise. Subsequently, the second motor 904 is activated, driving the screw 905 to rotate, moving the unfiltered part of the movable filter plate 903 to the bottom of the drain hole 203. At this time, the movable filter plate 903 in the filtered part drives the corresponding movable sealing column 301, and the movable sealing column 301 presses against the corresponding part. The detergent inside the infusion tube 302 flows to the nozzle 303, which sprays the detergent onto the surface of the moving filter plate 903. After the moving sealing column 301 stops, the second cylinder 406 at the corresponding position is activated. The second cylinder 406 drives the bristles 405 to rub back and forth on the surface of the moving filter plate 903 to clean it. While the moving filter plate 903 is moving, the unfiltered part of the moving filter plate 903 drives the corresponding moving sealing column 301 to move towards the center. At this time, a negative pressure is generated inside the corresponding part of the infusion tube 302, which opens the infusion port of the washing solvent tank 304, allowing the detergent inside the washing solvent tank 304 to enter the corresponding part of the infusion tube 302.
