Description

TECHNICAL FIELD

However, in the process of filtering the sewage, as the sewage treatment capacity increases, the impurities in the sewage will accumulate on the filter plate, at which time the impurities will block the filter holes on the filter plate, thereby affecting the flow rate of the sewage and also affecting the treatment efficiency of the sewage. At this time, the staff needs to disassemble and clean the filter plate, during which the equipment cannot treat the sewage, which will affect the treatment efficiency of the equipment on the sewage.

[0013] This invention also discloses a wastewater treatment method for a rural wastewater treatment device, which, using the aforementioned rural wastewater treatment device, includes the following steps: S1: First connect the top of the inlet chamber to the sewage discharge pipe. After the connection is completed, the sewage will enter the Y-shaped connecting pipe through the inlet chamber and the first discharge pipe, and finally be discharged through the Y-shaped connecting pipe. S2: As the amount of sewage treated increases, impurities in the sewage will accumulate on the surface of the conical funnel inside the first drain pipe. Then, through the timed operation of the alternating misalignment component, the conical funnel below the second drain pipe is inserted into the second drain pipe, while the conical funnel inside the first drain pipe is moved out of the first drain pipe. S3: The aqueous solution entering the inlet chamber will enter the Y-shaped connecting pipe through the second drain pipe, thereby allowing the conical funnel in the second drain pipe to filter the sewage. At the same time, the conical funnel separated from the first drain pipe will be connected to the rotating cleaning component. S4: As wastewater enters the inlet chamber, the rotating cleaning component will drive the conical funnel, which is separated from the first drain pipe, to rotate. This causes the impurities on the surface of the conical funnel to separate from the funnel under the action of centrifugal force, so that the impurities on the surface of the conical funnel fall into the inside of the discharge chamber and are finally discharged from the discharge chamber.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up alternating misalignment components and rotating cleaning components, as the wastewater is filtered, when a certain time is reached, the telescopic cylinder retracts through the operation of an external timer controller, causing the conical funnel below the second drain pipe to be inserted into the second drain pipe. This causes the second valve plate to block the first drain pipe, while the first valve plate loses its obstruction of the second drain pipe. The conical funnel inside the first drain pipe moves downward, and then the rotating cleaning components clean the conical funnel below the first drain pipe. In this way, the conical funnel can be cleaned without affecting the operation of the equipment, thereby improving the wastewater treatment efficiency. 2. By setting up a rotating cleaning component, when sewage passes through the inlet chamber, it will actuate the paddle plate to rotate. At this time, the paddle plate drives the first drive shaft to rotate through the third drive bevel gear, the second drive bevel gear, the second drive shaft, and the first drive bevel gear. This makes the turntable rotate synchronously with the first drive shaft. When the turntable rotates, it drives the first spur gear ring to rotate through the locking pin and positioning hole. This causes the first spur gear ring to actuate the second spur gear ring, which in turn rotates the conical funnel. As a result, the impurities accumulated on the conical funnel are separated from the conical funnel under the action of centrifugal force. In this process, there is no need for the staff to clean the conical funnel separately, and it does not affect the operation of the equipment. This not only reduces the labor intensity of the staff, but also further improves the efficiency of the equipment in treating sewage. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0019] Please see Figures 1-8 In this embodiment of the invention, a rural sewage treatment device includes a discharge bin 1. A crossbar 2 is installed on the inner wall of the discharge bin 1. An inlet bin 3 is provided at the top of the crossbar 2. A second drain pipe 13 is provided at the bottom of the inlet bin 3. A first drain pipe 9 is installed at the bottom of the inlet bin 3 on one side of the second drain pipe 13. The first drain pipe 9 and the second drain pipe 13 are symmetrically arranged along the vertical central axis of the inlet bin 3. A Y-shaped connecting pipe 8 is installed on the inner wall of the discharge bin 1, located below the first drain pipe 9. An alternating staggered component connected to the first drain pipe 9 and the second drain pipe 13 is provided at the top of the Y-shaped connecting pipe 8. A conical funnel 14 is connected to the top of the Y-shaped connecting pipe 8 through the alternating staggered component. A rotating cleaning component connected to the conical funnel 14 is provided on the inner side of the inlet bin 3.

[0020] In this embodiment: First, the top of the inlet chamber 3 is connected to the sewage discharge pipe. After the connection is completed, the sewage will enter the Y-shaped connecting pipe 8 through the inlet chamber 3 and the first discharge pipe 9, and finally be discharged through the Y-shaped connecting pipe 8. As the sewage treatment volume increases, impurities in the sewage will accumulate on the surface of the conical funnel 14 inside the first discharge pipe 9. Then, through the timed operation of the alternating misalignment component, the conical funnel 14 below the second discharge pipe 13 is inserted into the second discharge pipe 13, while the conical funnel 14 inside the first discharge pipe 9 is moved out of the first discharge pipe 9. At this time, the sewage enters the inlet chamber 3. The aqueous solution will then enter the Y-shaped connecting pipe 8 through the second drain pipe 13, thereby allowing the conical funnel 14 in the second drain pipe 13 to filter the sewage. At the same time, the conical funnel 14, which is separated from the first drain pipe 9, will be connected to the rotating cleaning device. As the sewage enters the inlet chamber 3, the rotating cleaning device will drive the conical funnel 14, which is separated from the first drain pipe 9, to rotate. This causes the impurities on the surface of the conical funnel 14 to separate from the conical funnel 14 under the action of centrifugal force, so that the impurities on the surface of the conical funnel 14 fall into the inner side of the discharge chamber 1 and are finally discharged from the discharge chamber 1.

[0021] Please refer to this carefully. Figure 2 , Figure 3 , Figure 7 , Figure 8The alternating misalignment component includes a second connecting plate 16 installed on the outer wall of the liquid inlet chamber 3. A telescopic cylinder 17 is installed at the bottom of the second connecting plate 16. The telescopic cylinder 17 is connected to an external timer controller via a wire. A first connecting plate 7 is installed at the end of the liquid inlet chamber 3 away from the second connecting plate 16. A corrugated telescopic tube 12 is provided at the top of the Y-shaped connecting pipe 8. A movable tube 10 is provided at the top of the corrugated telescopic tube 12. A conical funnel 14 is rotatably connected to the top of the movable tube 10. A guide rod 1 is installed on the outer wall of the movable tube 10 and is movably connected to the outer wall of the second drain pipe 13. 1. A second rotating shaft 31 is provided between the second drain pipe 13 and the first drain pipe 9. A first rotating shaft 30 is provided above the second rotating shaft 31 between the second drain pipe 13 and the first drain pipe 9. A first valve plate 28 located inside the second drain pipe 13 and a second valve plate 29 located inside the first drain pipe 9 are respectively installed at both ends of the first rotating shaft 30. A second rotating gear 36 is provided on the outside of the first rotating shaft 30. A first cam 32 is provided on the second rotating shaft 31. On one side of the second cam 33, the first cam 32 and the second cam 33 are each equipped with a first rotating gear 34 on the side closest to the vertical central axis of the second rotating shaft 31. Guide grooves 35 are provided on the side of the first cam 32 and the second cam 33 away from the first rotating gear 34. Guide plates 25, which are connected to the movable tube 10, are connected to the first cam 32 and the second cam 33 through the guide grooves 35. A support guide plate 41 is installed on one side of the first connecting plate 7. A first shifting rack 39, which meshes with the second rotating gear 36, is movably sleeved on the support guide plate 41. The first rotary gear 39 is connected to a second shift rack 40 that meshes with the first rotary gear 34. The output end of the telescopic cylinder 17 is connected to a first irregular guide rail 37 that is slidably connected to the first shift rack 39. The bottom of the first irregular guide rail 37 is provided with a second irregular guide rail 38 that is slidably connected to the second shift rack 40. The first irregular guide rail 37 is composed of a first vertical section 3701, a first inclined section 3702, and a second vertical section 3703. The second irregular guide rail 38 is composed of a second inclined section 3801, a second vertical section 3802, and a third inclined section 3803.

[0022] In this embodiment: when sewage enters the first drain pipe 9, it is filtered by the conical funnel 14 located inside the first drain pipe 9. At this time, impurities in the sewage will accumulate on the conical funnel 14. At the same time, the first valve plate 28 will block the second drain pipe 13. As the sewage is filtered, when a certain time is reached, the telescopic cylinder 17 retracts through the operation of an external timer controller. During this process, the second shift rack 40, under the pressure of the second inclined section 3801, shifts the first rotating gear 34 to rotate 90 degrees. At this time, the second cam 33 drives the movable pipe 10 below the second drain pipe 13 to move upward through the guide groove 35 and the guide frame plate 25, so that the conical funnel 14 below the second drain pipe 13 is engaged in the second drain pipe 13. At this time, the movable pipe 10 below the first drain pipe 9 is in a stationary state. At this time, the first vertical section 3701 cannot drive the first shift rack 39 to move. As the telescopic cylinder 17 retracts, the first inclined section 3702... By squeezing the first shift rack 39, the first shift rack 39 causes the second rotating gear 36 to rotate 90 degrees, thereby blocking the first drain pipe 9 with the second valve plate 29. At the same time, the first valve plate 28 loses its obstruction of the second drain pipe 13, allowing water to flow through the second drain pipe 13 into the Y-shaped connecting pipe 8. This allows the conical funnel 14 inside the second drain pipe 13 to filter the sewage. As the telescopic cylinder 17 continues to retract, the third inclined section 3803 squeezes the second shift rack 40, causing the protrusion of the first cam 32 to move the movable pipe 10 below the first drain pipe 9 downward through the guide groove 35 and the guide frame plate 25. This causes the conical funnel 14 inside the first drain pipe 9 to move downward. Then, the conical funnel 14 below the first drain pipe 9 is cleaned by rotating the cleaning component. In this way, the conical funnel 14 can be cleaned without affecting the operation of the equipment, thereby improving the sewage treatment efficiency.

[0023] Please refer to this carefully. Figure 7 , Figure 8 The first valve plate 28 and the second valve plate 29 are perpendicular to each other, and the protrusion of the second cam 33 faces the opposite direction to the protrusion of the first cam 32.

[0024] In this embodiment, the rotation of the first rotating shaft 30 causes the second valve plate 29 and the first valve plate 28 to alternately block the first drain pipe 9 and the second drain pipe 13.

[0025] Please refer to this carefully. Figure 2 , Figure 8 The guide groove 35 is provided along the edge of the second cam 33, and the top of the guide plate 25 is slidably connected to the second cam 33 through the guide groove 35.

[0026] In this embodiment, this structure is set so that when the second cam 33 rotates, it presses or pulls the guide plate 25 through the protrusion, thereby achieving stable vertical movement of the movable tube 10.

[0027] Please refer to this carefully. Figure 2 The bottom of the discharge hopper 1 is provided with a through hole, and the diameter of the outer wall of the bottom end of the Y-shaped connecting pipe 8 is smaller than the diameter of the through hole.

[0028] In this embodiment, this structure is designed to prevent the Y-shaped connecting pipe 8 from obstructing the bottom of the discharge bin 1, so that impurities falling into the discharge bin 1 can be discharged through the through hole at the bottom of the discharge bin 1.

[0029] Please refer to this carefully. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 The rotating cleaning component includes a plywood 27 rotatably connected to the inside of the liquid inlet chamber 3 via a rotating shaft. A third transmission bevel gear 26 is provided on the rotating shaft connecting the plywood 27 and the liquid inlet chamber 3. A second transmission shaft 6 extending to the outside of the liquid inlet chamber 3 is provided inside the liquid inlet chamber 3. Second transmission bevel gears 15 are symmetrically arranged at both ends of the second transmission shaft 6. A first transmission shaft 5 extending to the bottom of the crossbar 2 is provided at the top of the crossbar 2. A first transmission bevel gear 4 meshing with the second transmission bevel gear 15 is installed at the top of the first transmission shaft 5. The conical funnel 14... A second spur gear ring 24 is provided at the bottom outside the movable tube 10. A support frame 18 is installed on the outer wall of the movable tube 10. A first spur gear ring 23 that meshes with the second spur gear ring 24 is rotatably connected to the support frame 18 via a bearing. A turntable 20 located below the first spur gear ring 23 is installed at the bottom end of the first drive shaft 5. A positioning hole 22 is provided at the bottom of the first spur gear ring 23. A locking pin 19 extending to the inside of the positioning hole 22 is inserted into the turntable 20. A telescopic spring 21 connected to the locking pin 19 is provided at the bottom of the turntable 20.

[0030] In this embodiment: when the conical funnel 14 inside the first drain pipe 9 moves out of the first drain pipe 9, the movable pipe 10 will drive the first straight gear ring 23 to move downward through the support frame 18, so that the first straight gear ring 23 is fastened to the top of the locking pin 19 through the positioning hole 22. At this time, when the sewage passes through the inlet chamber 3, it will cause the page plate 27 to rotate. At this time, the page plate 27 drives the first transmission shaft 5 to rotate through the third transmission bevel gear 26, the second transmission bevel gear 15, the second transmission shaft 6, and the first transmission bevel gear 4, so that the turntable 20 moves with the first transmission shaft 5. When shaft 5 rotates synchronously, the turntable 20 rotates, driving the first spur gear ring 23 to rotate via the locking pin 19 and positioning hole 22. This causes the first spur gear ring 23 to rotate by turning the second spur gear ring 24, thereby causing the conical funnel 14 to rotate. As a result, the impurities accumulated on the conical funnel 14 are separated from the conical funnel 14 under the action of centrifugal force. During this process, there is no need for staff to clean the conical funnel 14 separately, and it does not affect the operation of the equipment. This not only reduces the labor intensity of the staff, but also further improves the efficiency of the equipment in treating sewage.

[0031] Please refer to this carefully. Figure 4 , Figure 5 The top of the locking pin 19 is rotatably connected to a ball bearing via a rotating shaft, and the positioning hole 22 has the same diameter as the top of the locking pin 19.

[0032] In this embodiment: when the support frame 18 drives the first spur gear ring 23 to move down, if the positioning hole 22 and the locking pin 19 are not aligned, the first spur gear ring 23 will squeeze the locking pin 19. As the turntable 20 rotates, when the locking pin 19 is aligned with the positioning hole 22, the locking pin 19 will be inserted into the positioning hole 22 under the elastic restoring force of the telescopic spring 21, preventing the locking pin 19 from having large friction with the first spur gear ring 23 when the locking pin 19 rotates relative to the first spur gear ring 23.

[0033] Please refer to this carefully. Figure 4 , Figure 5 The inner diameter of the first spur gear ring 23 is larger than the diameter of the first drive shaft 5, and the top of the support frame 18 is provided with a through groove with a diameter larger than that of the first drive shaft 5.

[0034] In this embodiment, this structure is designed to prevent friction between the support frame 18 and the first drive shaft 5 when the first spur gear ring 23 moves up and down.

[0035] Please refer to this carefully. Figure 5 The center of the first spur gear ring 23, the center of the turntable 20, and the center of the first transmission shaft 5 are coaxial.

[0036] In this embodiment, by setting this structure, the first spur gear ring 23 and the turntable 20 rotate coaxially when the locking pin 19 is inserted into the positioning hole 22, thereby improving the stability of the rotation of the first spur gear ring 23.

[0037] The following, in conjunction with the above-mentioned rural sewage treatment device, provides a sewage treatment method for a rural sewage treatment device, specifically including the following steps: S1: First connect the top of the liquid inlet 3 to the sewage discharge pipe. After the connection is completed, the sewage will enter the Y-type connecting pipe 8 through the liquid inlet 3 and the first discharge pipe 9, and finally be discharged through the Y-type connecting pipe 8. S2: As the sewage treatment volume increases, impurities in the sewage accumulate on the surface of the conical funnel 14 inside the first drain pipe 9. During sewage filtration, after a certain time, the telescopic cylinder 17 retracts via an external timer. During this process, the second shifting rack 40, under the pressure of the second inclined section 3801, rotates the first rotating gear 34 ninety degrees. At this time, the second cam 33, through the guide groove 35 and guide plate 25, moves the movable pipe 10 below the second drain pipe 13 upwards, causing the conical funnel 14 below the second drain pipe 13 to engage inside the second drain pipe 13. At this time, the movable pipe 10 below the first drain pipe 9 is stationary, and the first vertical section 3701 cannot move the first shifting rack 39. With the telescopic cylinder 17... The contraction of the first inclined section 3702 causes the first shift rack 39 to rotate the second rotating gear 36 by 90 degrees by squeezing the first shift rack 39. This causes the second valve plate 29 to block the first drain pipe 9, while the first valve plate 28 loses its blockage of the second drain pipe 13. This allows water to flow through the second drain pipe 13 into the Y-shaped connecting pipe 8, so that the conical funnel 14 inside the second drain pipe 13 filters the sewage. As the telescopic cylinder 17 continues to contract, the third inclined section 3803 squeezes the second shift rack 40, causing the protrusion of the first cam 32 to move the movable pipe 10 below the first drain pipe 9 downward through the guide groove 35 and the guide frame plate 25. This causes the conical funnel 14 inside the first drain pipe 9 to move downward. S3: The aqueous solution entering the inlet chamber 3 will enter the Y-shaped connecting pipe 8 through the second drain pipe 13, thereby allowing the conical funnel 14 in the second drain pipe 13 to filter the sewage. When the conical funnel 14 inside the first drain pipe 9 moves out of the first drain pipe 9, the movable pipe 10 will drive the first straight gear ring 23 to move down through the support frame 18, so that the first straight gear ring 23 is fastened to the top of the locking pin 19 through the positioning hole 22. S4: When the sewage passes through the inlet chamber 3, it will cause the paddle plate 27 to rotate. At this time, the paddle plate 27 drives the first transmission shaft 5 to rotate through the third transmission bevel gear 26, the second transmission bevel gear 15, the second transmission shaft 6, and the first transmission bevel gear 4. This makes the turntable 20 rotate synchronously with the first transmission shaft 5. When the turntable 20 rotates, it drives the first spur gear ring 23 to rotate through the locking pin 19 and the positioning hole 22. This causes the first spur gear ring 23 to drive the second spur gear ring 24 to rotate the conical funnel 14. This allows the impurities accumulated on the conical funnel 14 to separate from the conical funnel 14 under the action of centrifugal force. During this process, there is no need for the staff to clean the conical funnel 14 separately, and it does not affect the operation of the equipment. This not only reduces the labor intensity of the staff, but also further improves the sewage treatment efficiency of the equipment.

[0038] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
