Description

Technical Field

[0001] The present invention relates to the technical field of wastewater filtration, in particular to a wastewater filtration processor. Background Art

[0002] Wastewater treatment is to treat wastewater using physical, chemical and biological methods to purify wastewater, reduce pollution, and achieve the purpose of wastewater recycling and reuse, and fully utilize water resources;

[0003] Among them, physical wastewater treatment technology is a more common and practical method. It mainly targets impurities in water that can be removed through filtration, separation and other technologies. Drum-type wastewater filtration uses high-precision screens or filters to effectively intercept tiny suspended matter in the water. It has high filtration accuracy, is durable and easy to maintain, and has a wide range of applications. Therefore, this method has gradually become the first choice for wastewater filtration.

[0004] After filtering the wastewater, the existing wastewater filters will cause the intercepted impurities to firmly adhere to the inner wall of the filter cartridge due to the tension of the water, making it difficult to be washed off. With long-term attachment and the flow of water during filtration, the attached impurities will be stuck in the mesh of the filter cartridge. Although the impurities intercepted on the inner wall of the filter cartridge can be washed off by backwashing, the flushing water flow can only impact the impurities exposed inside the mesh. For some larger impurities, part of their area is directly adsorbed on the solid part of the inner wall of the filter cartridge. These parts firmly adsorb the impurities under the action of tension, making it difficult for these impurities to be washed out of the filter cartridge, thereby affecting the filtration efficiency of the wastewater. Summary of the Invention

[0005] The purpose of the present invention is to propose a wastewater filter processor to solve the problem that after a traditional filter cartridge intercepts large impurities, the impurities are firmly adsorbed on the inner wall of the filter cartridge and are difficult to be washed, resulting in low filtration efficiency of the filter cartridge.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical solution: a wastewater filter processor, comprising a filter and a multi-stage treatment assembly connected in series on one side of the filter, and further comprising a filter cartridge rotatably connected to the interior of the filter for filtering the wastewater, a partition frame movably connected between the front end of the filter cartridge and the filter, a collection tank being provided inside the filter cartridge, a collection chamber being formed between the inner wall of the filter and the filter cartridge, and a flushing pipe being fixedly connected to the upper portion of the collection chamber;

[0007] The inner wall of the upper end of the filter is provided with a knocking assembly for assisting in flushing impurities attached to the inner wall of the filter cartridge. The knocking assembly includes a fixed cylinder fixedly connected to the inner wall of the upper end of the filter, and a movable rod is movably connected inside the fixed cylinder. The outer wall of the filter cartridge is fixedly connected to a magnetic strip in an annular array, and a plurality of the magnetic strips are staggered with opposite magnetic poles. The surface of the movable rod is fixedly connected to a magnet.

[0008] As a further description of the above technical solution:

[0009] The fixing cylinder is internally movably connected to a limit block, and the limit block and the movable rod are rotatably connected to a connecting block via a rotating shaft, and a torsion spring is provided between the rotating shaft, the limit block and the movable rod.

[0010] As a further description of the above technical solution:

[0011] When the movable rod hits the surface of the filter cartridge, the upper part of the limit block is located inside the fixed cartridge, and the connection between the limit block and the connecting block extends to the outside of the fixed cartridge. A spring is fixedly connected between the upper end of the limit block and the fixed cartridge.

[0012] As a further description of the above technical solution:

[0013] A flushing assembly is provided at the bottom of the flushing pipe, and the flushing assembly includes a flushing head fixedly connected to the bottom of the flushing pipe, a telescopic head is slidably connected inside the flushing head, a connecting rod is fixedly connected between the telescopic head and the movable rod, and the internal top end of the flushing pipe is located directly above the telescopic head and is fixedly connected to a head.

[0014] As a further description of the above technical solution:

[0015] The telescopic head is in the shape of a tube with two ends open, and after the telescopic head is retracted to the inside of the flushing pipe, it can be sleeved on the outside of the head. The telescopic head is made of rubber material.

[0016] As a further description of the above technical solution:

[0017] The flushing component and the knocking component are both located directly above the collecting tank, and the knocking component is located on the side of the flushing component away from the multi-stage processing component, and the filter cartridge rotates counterclockwise toward the multi-stage processing component.

[0018] As a further description of the above technical solution:

[0019] The other side of the filter is fixedly connected to a water inlet pipe, the rear end of the filter is fixedly connected to a motor for driving the filter cartridge to rotate, the front end of the collection tank is fixedly connected to a sewage pipe, and the sewage pipe passes through and extends to the outside of the filter, the bottom of the flushing pipe is fixedly connected to a water pump, and a water pump is provided at the bottom of the water pump.

[0020] As a further description of the above technical solution:

[0021] The multi-stage treatment component includes a biochemical filtration chamber, a disinfection chamber and a sedimentation chamber which are sequentially arranged on one side of the filter. The filter, biochemical filtration chamber, disinfection chamber and sedimentation chamber are all fixedly connected through a water pipe, and a ball valve is provided in the middle of the water pipe.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] The filter cartridge is vibrated by knocking, and the movable rod is first pushed to move by magnetic repulsion and cooperates with the spring to form a stored force, and then the movable rod is knocked on the filter cartridge by magnetic attraction. Not only is the gravitational potential energy during knocking increased by increasing the displacement distance, but the force of the movable rod knocking on the filter cartridge is geometrically increased in combination with the spring force storage, so that the vibration amplitude of the filter cartridge increases after being knocked, thereby reducing the adsorption force of impurities on the inner wall of the filter cartridge, making it easier to wash away impurities attached to the inner wall of the filter cartridge, ensuring the smooth flow of the filter cartridge and ensuring that the filtering effect of the filter cartridge is not affected. At the same time, the knocking of the movable rod will cause the knocked part of the filter cartridge to deform, and the deformation of the knocked part of the filter cartridge can destroy the tension of the inner wall of the filter cartridge, thereby further making it easier to wash away impurities attached to the inner wall of the filter cartridge, further improving the flushing effect of the filter cartridge.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figure 1-Figure 7 As shown, the present invention provides a wastewater filtration processor: comprising a filter 10 and a multi-stage treatment component 20 connected in series on one side of the filter 10, the other side of the filter 10 is fixedly connected to a water inlet pipe 11, the rear end of the filter 10 is fixedly connected to a motor 13 for driving the filter cartridge 12 to rotate, the front end of the collection tank 15 is fixedly connected to a sewage pipe 16, and the sewage pipe 16 passes through and extends to the outside of the filter 10, the multi-stage treatment component 20 includes a biochemical filtration tank 21, a disinfection tank 22 and a sedimentation tank 23 sequentially arranged on one side of the filter 10, the filter 10, the biochemical filtration tank 21, the disinfection tank 22 and the sedimentation tank 23 The bin 21, the disinfection bin 22 and the sedimentation bin 23 are all fixedly connected by a water conduit 24, and a ball valve 25 is provided in the middle of the water conduit 24. It also includes a filter cartridge 12 rotatably connected to the inside of the filter 10 for filtering wastewater. A partition frame 14 is movably connected between the front end of the filter cartridge 12 and the filter 10. A collecting tank 15 is provided inside the filter cartridge 12. A collecting chamber 17 is formed between the inner wall of the filter 10 and the filter cartridge 12, and a flushing pipe 18 is fixedly connected to the upper part of the collecting chamber 17. A water pump 19 is fixedly connected to the bottom of the flushing pipe 18, and a water pump is provided at the bottom of the water pump 19;

[0039] The upper inner wall of the filter 10 is provided with a knocking assembly 30 for assisting in flushing impurities attached to the inner wall of the filter cartridge 12. The knocking assembly 30 includes a fixed cylinder 31 fixedly connected to the upper inner wall of the filter 10, and a movable rod 32 is movably connected inside the fixed cylinder 31. The outer wall of the filter cartridge 12 is fixedly connected to a magnetic strip 35 in an annular array. The multiple magnetic strips 35 are staggered with opposite magnetic poles. A magnet 34 is fixedly connected to the surface of the movable rod 32. The knocking assembly 30 is located directly above the collection tank 15. The filter cartridge 12 rotates counterclockwise toward the multi-stage processing assembly 20.

[0040] The fixed cylinder 31 is internally connected to a limit block 36, and the limit block 36 and the movable rod 32 are rotatably connected to a connecting block 37 via a rotating shaft 38. A torsion spring is provided between the rotating shaft 38, the limit block 36 and the movable rod 32.

[0041] When the movable rod 32 hits the surface of the filter cartridge 12, the upper part of the limit block 36 is located inside the fixed cylinder 31, and the connection between the limit block 36 and the connecting block 37 extends to the outside of the fixed cylinder 31. A spring 33 is fixedly connected between the upper end of the limit block 36 and the fixed cylinder 31.

[0042] Specifically, the wastewater to be treated is first introduced into the interior of the filter 10 through the water inlet pipe 11. After the wastewater is physically filtered by the filter 10, the filtered wastewater is controlled by the ball valve 25 to enter the biochemical filtration chamber 21 through the water conduit 24 for biochemical filtration. The wastewater after biochemical filtration is also controlled by the ball valve 25 to enter the disinfection chamber 22 through the water conduit 24 for disinfection. The disinfected wastewater is again controlled by the ball valve 25 to enter the sedimentation chamber 23 through the water conduit 24 for sedimentation, thus completing the filtration treatment of the wastewater.

[0043] When the wastewater is physically filtered, after the wastewater enters the filter 10, the filter cartridge 12 and the filter 10 are isolated by the partition frame 14, so that the wastewater can only enter the interior of the filter cartridge 12 from the front of the filter cartridge 12. After the wastewater enters the filter cartridge 12, it is filtered by the filter cartridge 12 and flows into the collection chamber 17, while the impurities in the wastewater will be intercepted by the filter cartridge 12 and attached to the inner wall of the filter cartridge 12. In this process, the motor 13 is started and the filter cartridge 12 is rotated by its output shaft. When the filter cartridge 12 rotates, the intercepted impurities will be driven to rotate synchronously to the top. Under the action of the impurities' own gravity and the flushing of the flushing pipe 18, the intercepted impurities fall off from the inner wall of the filter cartridge 12 and fall into the collection tank 15. Then, the impurities collected by the filtration are discharged to the outside of the filter 10 by the sewage pipe 16. The water used for flushing is the water that has been preliminarily filtered in the collection chamber 17 and introduced into the flushing pipe 18 through the water pump and sprayed out. There is no need to use a clean water source, which reduces the waste of water resources.

[0044] However, due to the large size of some impurities, part of their area is directly adsorbed on the solid part of the inner wall of the filter cartridge 12. These parts firmly adsorb the impurities under the action of tension, making it difficult for these impurities to be washed out of the filter cartridge 12, thereby affecting the filtration efficiency of the wastewater.

[0045] Based on this, by setting a knocking assembly 30 between the filter cartridge 12 and the filter 10, when the filter cartridge 12 rotates, the magnetic strips 35 on its surface will rotate synchronously with it, and because the multiple magnetic strips 35 are staggered with opposite magnetic poles, when the magnetic strips 35 with the same magnetic pole as the magnet 34 rotate to just below the magnet 34, the magnet 34 will be pushed upward by the action of magnetic repulsion, and when the magnet 34 moves upward, it will drive the movable rod 32 to slide toward the inside of the fixed cylinder 31, so that the movable rod 32 moves in the direction away from the filter cartridge 12, and then when the magnetic strips 35 with different magnetic poles from the magnet 34 rotate to just below the magnet 34, it will attract the magnet 34 to approach it under the action of magnetic attraction, so that the magnet 34 drives the movable rod 32 to move toward the filter cartridge 12 and The surface of the filter cartridge 12 is knocked, and the filter cartridge 12 is vibrated by knocking, and the movable rod 32 is first pushed to move by magnetic repulsion and cooperates with the spring 33 to form a stored force, and then the magnetic attraction is used to make the movable rod 32 knock the filter cartridge 12, which not only increases the gravitational potential energy during knocking by increasing the displacement distance, but also cooperates with the spring stored force 33 to make the force of the movable rod 32 knocking the filter cartridge 12 increase geometrically, so that the vibration amplitude of the filter cartridge 12 increases after being knocked, thereby reducing the adsorption force of impurities on the inner wall of the filter cartridge 12, making it easier to wash away impurities attached to the inner wall of the filter cartridge 12, ensuring the smooth flow of the filter cartridge 12 and ensuring that the filtering effect of the filter cartridge 12 is not affected. At the same time, the knocking of the movable rod 32 will cause the knocked part of the filter cartridge 12 to appear as if attached Figure 5 The deformation shown in FIG. 1 can destroy the tension of the inner wall of the filter cartridge 12 through the deformation of the knocking part of the filter cartridge 12, thereby further making it easier to wash away the impurities attached to the inner wall of the filter cartridge 12, further improving the washing effect of the filter cartridge 12;

[0046] In addition, when the movable rod 32 knocks on the surface of the filter cartridge 12, the movable rod 32 is completely extended out of the fixed cylinder 31. At this time, since the movable rod 32 is movably connected to the limit block 36 through the connecting block 37, and the movable rod 32 and the connecting block 37 can rotate through the rotating shaft 38, when the movable rod 32 touches the filter cartridge 12, the filter cartridge 12 will apply a reaction force to the movable rod 32, causing the movable rod 32 to rotate around the rotating shaft 38 as the axis. When the movable rod 32 rotates, its bottom will slide against the surface of the filter cartridge 12, thereby making the filter The cylinder 12 undergoes creeping deformation at the point where it is struck, thereby increasing the deformation range of the filter cylinder 12 and increasing the area of ​​damage to the tension of the inner wall of the filter cylinder 12, further enabling the impurities attached to the inner wall of the filter cylinder 12 to be easily washed off, thereby ensuring the filtering effect of the filter cylinder 12. Moreover, since a torsion spring is provided between the rotating shaft 38, the limit block 36 and the movable rod 32, when the movable rod 32 is no longer in contact with the filter cylinder 12, the elastic reset action of the torsion spring can drive the movable rod 32 to rotate to its original state, so that the movable rod 32 can smoothly retract into the interior of the fixed cylinder 31.

[0047] like Figure 7 and Figure 8 As shown, a flushing assembly 40 is provided at the bottom of the flushing pipe 18, and the flushing assembly 40 includes a flushing head 41 fixedly connected to the bottom of the flushing pipe 18, and a telescopic head 42 is slidably connected inside the flushing head 41, and a connecting rod 44 is fixedly connected between the telescopic head 42 and the movable rod 32. The inner top end of the flushing pipe 18 is located directly above the telescopic head 42 and is fixedly connected to a head 43; the telescopic head 42 is a tubular with open ends, and the telescopic head 42 can be sleeved on the outside of the head 43 after shrinking to the inside of the flushing pipe 18. The telescopic head 42 is made of rubber material. The flushing assembly 40 is located directly above the collection tank 15, and the knocking assembly 30 is located on the side of the flushing assembly 40 away from the multi-stage treatment assembly 20.

[0048] Specifically, when flushing the filter cartridge 12, the water initially filtered inside the collection chamber 17 is first introduced into the flushing pipe 18 through the pumping pipe 19 by the water pump, and then sprayed out by the flushing head 41 to flush the surface of the filter cartridge 12. During the flushing process, the flushing water will fall into the collection tank 15 along with the washed impurities and be discharged through the sewage pipe 16, which will cause unnecessary waste of the initially treated sewage.

[0049] Based on this, by arranging the head 43 inside the flushing pipe 18, the telescopic head 42 is sleeved on the outside of the head 43 in the initial state, the telescopic head 42 is blocked by the head 43, and the telescopic head 42 is connected to the movable rod 32 by the connecting rod 44. Therefore, when the movable rod 32 knocks the filter cartridge 12, the movable rod 32 moves downward and the connecting rod 44 drives the telescopic head 42 to move downward synchronously, so that the telescopic head 42 is separated from the head 43. At this time, the telescopic head 42 is in the open state, and the water inside the flushing pipe 18 is sprayed out through the telescopic head 42 to flush the surface of the filter cartridge 12, so that the flushing component 40 and the knocking component 30 work synchronously. On the one hand, flushing is easier after knocking, and on the other hand, there is no need to flush continuously, which saves a lot of water resources.

[0050] Furthermore, since the telescopic head 42 is made of rubber and is capable of deformation, when the movable rod 32 is rotated and displaced, the connecting rod 44 is also used to drive the telescopic head 42 to bend synchronously, thereby changing the original fixed-point flushing into a range-varying flushing, increasing the flushing area and further improving the flushing effect of impurities on the inner wall of the filter cartridge 12;

[0051] In addition, when the telescopic head 42 is blocked by the sealing head 43, static water pressure is formed inside the flushing pipe 18, and when the telescopic head 42 is opened, water is sprayed out from the flushing pipe 18 to form dynamic water pressure. The pressure released at the moment when the water pressure is converted from static to dynamic is greater than the static pressure during continuous flushing. Therefore, this method not only saves water resources, but also increases the flushing pressure, so that the flushing effect of impurities on the inner wall of the filter cartridge 12 is further improved, so that the filter cartridge 12 can filter smoothly, and the filtering effect of the filter cartridge 12 is guaranteed.

[0052] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
