Description

Technical Field

[0001] This utility model relates to the field of water filtration device technology, and in particular to a water pollution filtration device. Background Technology

[0002] Water pollution prevention and control is dedicated to preventing and controlling water quality deterioration caused by the introduction of substances, which alters the chemical, physical, biological, or radioactive properties of water bodies, thereby affecting the effective use of water, endangering human health, and damaging the ecological environment. Wastewater treatment devices are an important means to achieve this goal, removing impurities from wastewater and purifying water bodies through filtration and other methods.

[0003] A search revealed a water pollution filtration device disclosed in patent application number CN202321373524.6. The device includes a filter box, a filter cylinder fixedly mounted inside the filter box, an auger rotatably mounted inside the filter cylinder, and multiple evenly distributed filter holes on the outer circumference of the filter cylinder. A motor is fixedly mounted on the outer wall of the filter box, with its output end fixed to the auger. A debris removal pipe is fixedly mounted at the bottom of the filter cylinder, containing a solenoid valve. The bottom end of the debris removal pipe penetrates the side wall of the filter box. An activated carbon filter plate is mounted inside the filter box below the filter cylinder. The motor drives the auger to rotate, agitating the wastewater inside the filter cylinder and thoroughly mixing it with the purifying agent. The wastewater is then filtered through the multiple filter holes, trapping impurities inside the filter cylinder while allowing it to flow out. When there are many impurities in the filter cylinder, the water inlet is stopped, the solenoid valve is opened, and the auger rotates, moving the impurities towards the debris removal pipe for discharge. This process is very convenient for removing impurities.

[0004] The above-mentioned device has a drawback: when it is necessary to clean the impurities on the filter cartridge or replace the filter cartridge, the equipment needs to be shut down, that is, the water inlet pipe needs to be stopped. This may cause the sewage at the source to be temporarily stored and accumulated, affecting the sewage filtration efficiency. Therefore, in order to improve the sewage filtration efficiency, that is, to filter sewage without stopping the machine when replacing the filter cartridge, this device is designed as a water pollution filtration device.

[0041] Example 1

[0042] See attached document Figure 1-4 The device includes a housing 10, an inlet pipe a11, an inlet pipe b111, a reversing mechanism, two sets of filter components 20, a first drainage component, and a second drainage component. This device can be used for filtering domestic sewage. When filtering sewage, the device is equipped with a first water storage tank 101 and a second water storage tank 102. Sewage can be filtered when the inlet pipe b111 faces either the first or second water storage tank. When it is necessary to clean one of the filter components 20, for example, when cleaning the filter component 20 in the first filter box 103, the reversing mechanism can be activated to adjust the outlet of the inlet pipe b111 towards the second water storage tank 102. At this time, no more water enters the first filter box 103, allowing the filter component 20 in the first filter box 103 to be replaced. While replacing the filter component 20 in the first filter box 103, the filter component 20 inside the second filter box 104 can still filter water, thus allowing for the replacement of the filter component 20 in the first filter box 103 without shutting down the machine.

[0043] Specifically, the tank 10 contains a first water storage tank 101 and a second water storage tank 102. Both the first and second water storage tanks 101 and 102 have outlet pipes 12 installed at their bottom ends. An inlet pipe a11 is installed on the top wall of the tank 10. An inlet pipe b111 is rotatably and sealed to the bottom end of inlet pipe a11 (inlet pipe b111 can be installed on inlet pipe a11 via a sealed rotary joint). A reversing mechanism is located outside inlet pipe b111, used to adjust the outlet direction of inlet pipe b111. The interior of the tank 10 is located below the two outlet pipes 12. The system has two independent filter boxes 103 and 104, with two sets of filter components 20 installed inside the first filter box 103 and the second filter box 104, respectively. The first drainage component and the second drainage component are installed on the bottom wall of the box body 10. The first drainage component is used to drain the water in the first filter box 103, and the second drainage component is used to drain the water in the second filter box 104. The top of the adjacent sides of the first water storage tank 101 and the second water storage tank 102 are connected, that is, the water inlet pipe b111 can rotate within the connected space to switch positions.

[0044] In one embodiment of this utility model, the reversing mechanism includes a driven gear 1111, a driving gear 1112, and a servo motor 1113 (the driven gear 1111 and the driving gear 1112 may be made of stainless steel); the driven gear 1111 is fixedly installed on the outer wall of the water inlet pipe b111; the servo motor 1113 is fixedly installed on the outer top wall of the housing 10, and the output shaft of the servo motor 1113 movably passes through the top wall of the housing 10 and extends into the interior of the housing 10; the driving gear 1112 is fixedly installed on the bottom wall of the output shaft of the servo motor 1113, and the driving gear 1112 and the driven gear 1111 mesh; wherein, by activating the reversing mechanism, the outlet direction of the water inlet pipe b111 can be changed to... The internal switching between the first water tank 101 and the second water tank 102; when it is necessary to change the orientation of the water inlet pipe b111, the servo motor 1113 can be started. The servo motor 1113 drives the drive gear 1112 to rotate. The teeth on the outer wall of the drive gear 1112 mesh with the teeth on the outer wall of the driven gear 1111, thereby driving the driven gear 1111 to rotate, and then driving the water inlet pipe b111 to rotate. After the water inlet pipe b111 rotates, the orientation of the water outlet of the water inlet pipe b111 can be changed. It should also be noted that an encoder is installed on the output shaft of the servo motor 1113. The encoder and the servo motor 1113 are electrically connected to the controller. The encoder limits the rotation angle of the output shaft of the servo motor 1113.

[0045] The filter assembly 20 includes a mounting bracket 201, a filter screen 202, and a threaded locking rod 204. A mounting groove 203 is provided on the outer wall of the housing 10, and the mounting bracket 201 is slidably mounted inside the mounting groove 203. The filter screen 202 is fixedly mounted on the mounting bracket 201. A positioning hole plate is fixedly mounted on the outer wall of the mounting bracket 201, and the threaded locking rod 204 is movably mounted on the positioning hole plate. A threaded mounting hole is provided on the side wall of the housing 10, and the threaded locking rod 204 is threadedly connected to the threaded mounting hole. Here, the filter... Component 20 is detachable. To disassemble, first rotate the threaded locking rod 204 counterclockwise to release the threaded locking rod 204 from fixing the mounting bracket 201, and then pull the mounting bracket 201 out of the mounting groove 203. In addition, a rubber pad is provided on the outer wall of the mounting bracket 201. When the mounting bracket 201 is pushed into the interior of the mounting groove 203, the sealing pad fits against the outer wall of the housing 10 to prevent water leakage. Furthermore, the application can be used to filter solid impurities in sewage, and the filter screen can be made of polyester fiber.

[0046] In one embodiment of this utility model, the first drainage assembly includes a first drainage pipe 13, a main pipe 14, a second sewage pipe 18, and a three-way valve b192. The first drainage pipe 13 is installed on the bottom wall of the housing 10 and is connected to the interior of the first filter box 103. The inlet of the three-way valve b192 is installed on the outlet of the first drainage pipe 13. The inlets of the main pipe 14 and the second sewage pipe 18 are respectively installed on the two outlets of the three-way valve b192. When sewage enters from the first water storage tank 101, the sewage enters the first filter box 103 from the interior of the outlet pipe 12. After being filtered by the filter assembly 20 in the first filter box 103, it enters the first drainage pipe 13. When draining the filtered water, the three-way valve b192 can be rotated to close the second sewage pipe 18. At this time, the filtered water can flow from the first drainage pipe 13 into the interior of the main pipe 14, and then enter the next stage of filtration equipment from the main pipe 14.

[0047] Additionally, a second drain pipe 18 is provided here. When cleaning the inner wall of the first filter box 103, the wastewater can be discharged from the second drain pipe 18 without affecting the normal discharge of filtered water in the second filter box 104. The specific principle is as follows: when the filter component 20 in the first filter box 103 is pulled out, if it is necessary to rinse the inner wall of the first filter box 103 with clean water, the three-way valve b192 can be rotated to block the water from flowing from the first drain pipe 13 into the main pipe 14, so that the water in the first drain pipe 13 can flow into the interior of the second drain pipe 18. In this way, when the cleaning water in the first filter box 103 is released, the cleaning water will not be discharged into the main pipe 14.

[0048] In one embodiment of this utility model, the second drainage assembly includes a second drainage pipe 15, a first sewage pipe 16, a connecting pipe 17, and a three-way valve a191; the second drainage pipe 15 is installed on the bottom wall of the housing 10 and communicates with the interior of the second filter box 104; the inlet of the three-way valve a191 is installed on the outlet of the second drainage pipe 15; the inlets of the first sewage pipe 16 and the connecting pipe 17 are respectively installed on the two outlets of the three-way valve a191; the connecting pipe 17 is installed away from the outlet of the three-way valve a191. It is connected to the inside of the main pipe 14; when sewage enters from the second water storage tank 102, the sewage enters the second filter box 104 from the inside of the outlet pipe 12, and after being filtered by the filter component 20 in the second filter box 104, it enters the second drain pipe 15. When draining the filtered water, the three-way valve a191 can be rotated to close the passage of the first sewage pipe 16, so that the filtered water can flow from the second drain pipe 15 to the inside of the connecting pipe 17, and then flow to the main pipe 14 through the connecting pipe 17;

[0049] In addition, when cleaning the inner wall of the second filter box 104 after removing the filter assembly 20 in the second filter box 104, the three-way valve a191 can be rotated to close the channel between the second drain pipe 15 and the connecting pipe 17, so that the cleaning water flows from the second drain pipe 15 into the interior of the first drain pipe 16 and is discharged from the interior of the first drain pipe 16, that is, the cleaning water will not be discharged into the main pipe 14.

[0050] In this embodiment, the working principle of the device is as follows: sewage first enters the device through the inlet pipe a11 and is then transported downwards through the inlet pipe b111. Under normal conditions, the outlet of the inlet pipe b111 is aligned with the first water storage tank 101. After the sewage flows into the first water storage tank 101, it enters the first filter box 103 through the outlet pipe 12 at its bottom. The filter component 20 in the first filter box 103 filters the sewage and intercepts solid impurities. The filtered water enters the three-way valve b192 through the first drain pipe 13. At this time, the three-way valve b192 is rotated to close the second drain pipe 18, and the filtered water is transported to the next stage of treatment equipment through the main pipe 14.

[0051] When it is necessary to replace the filter component 20 in the first filter box 103, the reversing mechanism is activated: the servo motor 1113 drives the drive gear 1112 to rotate, the drive gear 1112 meshes with the driven gear 1111, and drives the inlet pipe b111 to rotate in a sealed manner, so that its outlet is switched to the second water storage tank 102. At this time, the sewage is diverted to flow into the second water storage tank 102, and enters the second filter box 104 through the outlet pipe 12. After being filtered by the filter component 20 inside, it enters the three-way valve a191 through the second drain pipe 15. After the first sewage pipe 16 is closed, the filtered water flows into the main pipe 14 through the connecting pipe 17 to ensure continuous water supply.

[0052] When replacing the filter element 20 of the first filter box 103, turn the threaded locking rod 204 counterclockwise to release the fixation, and pull out the mounting bracket 201 to replace the filter screen 202. When installing, push the mounting bracket 201 back and tighten the threaded locking rod 204, and ensure the rubber gasket is sealed. If it is necessary to clean the inner wall of the first filter box 103, rotate the three-way valve b192 to close the main pipe 14 passage, and the cleaning wastewater will be discharged from the second drain pipe 18 without affecting the normal operation of the second filter box 104. Similarly, when replacing the filter element 20 of the second filter box 104, switch the inlet pipe b111 to the first water storage tank 101 through the reversing mechanism. The operation procedure is the same as above, realizing maintenance without stopping the machine and improving the filtration efficiency.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
