Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0029] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0030] Embodiment 1

[0031] Please refer to Figures 1-13 , the present invention provides a technical solution: a vertical double-stage cyclone dirt collector, which includes a tank body 1 and a dirt collection box 2 installed at the bottom end of the tank body 1. A water inlet pipe 4 is fixedly connected to an outer wall of one side of the tank body 1. A funnel 5 adapted to the water inlet pipe 4 is arranged on an inner wall of the tank body 1. A water delivery sleeve 6 is fixedly connected to a central position of the inner wall of the tank body 1 where the funnel 5 is located. A first cyclone assembly for primary treatment of sewage is arranged on an inner wall of the funnel 5. A second cyclone assembly for secondary treatment of sewage is arranged on an inner wall of the water delivery sleeve 6. The second cyclone assembly includes a motor 3, an aeration mechanism, and a water pumping mechanism. A connecting shaft 20 is installed on an outer wall of one end of the motor 3. A spiral blade 21 adapted to the water delivery sleeve 6 is arranged on an outer wall of the connecting shaft 20. A plurality of sewage discharge ports 22 are formed on an outer wall of the top end of the water delivery sleeve 6. A drain pipe 23 extending out of the tank body 1 is fixedly connected to a position of the water delivery sleeve 6 above the sewage discharge ports 22. An aeration mechanism for aerating the sewage during secondary treatment is arranged on an outer wall of the top end of the water delivery sleeve 6. A water pumping assembly for pumping the dirt collection box 2 is arranged on an inner wall of the tank body 1.

[0032] In use, sewage is injected into the interior of the tank body 1 through the water inlet pipe 4, causing the sewage to enter the interior of the funnel 5. During this process, the sewage will rotate and fall along the outer wall of the funnel 5, enabling the sewage to enter the interior of the first cyclone assembly, thereby accelerating the swirling of the sewage. As a result, the particulate matter in the sewage is thrown towards the inner wall direction of the funnel 5 under the action of centrifugal force, water flow drag, and its own gravity, thus completing the primary separation of the particulate matter in the sewage. The sewage after the primary separation will enter the bottom of the tank body 1. At this time, an external power supply is connected, the motor 3 is started, and the spiral blade 21 is driven to rotate inside the water delivery sleeve 6 through the connecting shaft 20, thereby changing the flow direction of the sewage inside the tank body 1, causing the sewage to enter the interior of the water delivery sleeve 6 and rise. During this process, the connecting shaft 20 will drive the aeration mechanism to work and aerate the sewage inside the water delivery sleeve 6, enabling the bubbles and turbulence to drive the movement of the particles, increasing the chance of collision and aggregation between the particles to form larger particulate matter. At the same time, the rotation of the spiral blade 21 will also accelerate the swirling of the sewage inside the water delivery sleeve 6, causing the particulate matter in the sewage to be thrown towards the inner wall direction of the water delivery sleeve 6 under the action of centrifugal force, water flow drag, and its own gravity. Then, under the action of centrifugal force, the large particulate matter together with a small amount of sewage is thrown out through the sewage discharge port 22 and returns to the interior of the funnel 5 again, thus completing the secondary separation of the sewage. The separated sewage will be discharged through the drain pipe 23, while the separated particles together with a part of the sewage enter the interior of the sewage collection tank 2, and the pumping assembly can pump the sewage entering the interior of the sewage collection tank 2 back into the interior of the tank body 1 for separation.

[0033] Please refer to Figure 2 and Figure 5 , the height of the water inlet end and the water outlet end of the water inlet pipe 4 is different and they are not in the same plane. The sewage discharge port 22 is inclined in the rotation direction of the spiral blade 21, and the opening on the outer wall of the water delivery sleeve 6 is lower than the opening on the inner wall of the water delivery sleeve 6. The drain pipe 23 is inclined downward.

[0034] When injecting sewage into the interior of the tank body 1 through the water inlet pipe 4, the sewage will obliquely fall onto the slope of the upper half of the funnel 5, and with the impact force of the sewage, the sewage will swirl along the slope of the upper half of the funnel 5, thereby accelerating the swirling efficiency of the sewage. And the swirling of the sewage driven by the spiral blade 21 makes it easier for the particles in the sewage to enter the interior of the sewage discharge port 22, and then the particles will fall onto the interior of the funnel 5 along the inclined surface of the sewage discharge port 22. Due to the downward inclination of the drain pipe 23, the sewage that rises to the top of the water delivery sleeve 6 will be discharged from the tank body 1 along the drain pipe 23.

[0035] Please refer to Figure 6 , the spiral blade 21 includes a lower spiral blade 211 and an upper spiral blade 212. The outer diameter dimension of the spiral blade 21 matches the inner diameter dimension of the water delivery sleeve 6, and the outer diameter dimension of the lower spiral blade 211 is smaller than the outer diameter dimension of the upper spiral blade 212.

[0036] During use, when the sewage rises to the position of the upper spiral blade 212 through the lower spiral blade 211 inside the water delivery sleeve 6, the swirling space of the sewage will increase, thereby increasing the centrifugal force on the particulate matter in the sewage and the dragging force of the water flow.

[0037] Please refer to Figures 2-4 , the first swirling assembly includes a spiral guide vane 8 arranged on the inner wall of the funnel 5 and fixedly connected to the water delivery sleeve 6. A rotating frame 9 is rotatably connected to the outer wall at the bottom end of the funnel 5. A filter screen 10 is coated on the outer wall of the rotating frame 9. A plurality of groups of force-receiving plates 11 are arranged on the inner periphery of the rotating frame 9 in the circumferential direction. A plurality of groups of scraping plates 12 are arranged on the inner periphery at the bottom end of the rotating frame 9 in the circumferential direction. One end of the scraping plate 12 close to the water delivery sleeve 6 is fixedly connected to a pressing block 13. A pressing block 57 is fixedly connected to the outer wall at the bottom end of the rotating frame 9.

[0038] During use, the sewage inside the funnel 5 will rotate and flow downward under the action of the spiral guide vane 8. The particulate matter is thrown towards the inner wall direction of the funnel 5 under the action of the inertial centrifugal force of the fluid and its own gravity, thereby realizing the rapid separation of the particles and the sewage. After the sewage passes through the spiral guide vane 8, it will enter the inside of the rotating frame 9 and impact the force-receiving plates 11 on the inner wall of the rotating frame 9. The impact force of the sewage on the force-receiving plates 11 is used to push the rotating frame 9 to rotate at a high speed on the surface of the funnel 5, thereby increasing the centrifugal force of the sewage inside the rotating frame 9. The sewage is thrown out from the inside of the rotating frame 9 under the action of the centrifugal force, and the particulate matter in the sewage is filtered through the filter screen 10, so that the particulate matter is intercepted inside the rotating frame 9. While the rotating frame 9 is rotating, it will drive the scraping plate 12 to rotate synchronously. The rotation of the scraping plate 12 can be used to scrape the particulate matter falling to the bottom of the rotating frame 9 towards the water delivery sleeve 6.

[0039] Please refer to Figure 4 and Figure 11 , the first swirling assembly further includes a fixed column 7 installed at the bottom end of the water delivery sleeve 6 and extending into the sewage collection box 2. A plurality of groups of sewage discharge grooves 14 are arranged on the inner wall at the bottom end of the water delivery sleeve 6 in the circumferential direction. A first limiting plate 15 adapted to the sewage discharge grooves 14 is arranged on the outer wall of the water delivery sleeve 6. A first limiting spring 16 adapted to the first limiting plate 15 is arranged on the inner wall of the water delivery sleeve 6. A force-receiving block 17 adapted to the pressing block 13 is arranged on the outer wall at the top end of the first limiting plate 15. A groove 18 adapted to the force-receiving block 17 is arranged on the inner wall at the bottom end of the rotating frame 9. A channel 19 adapted to the sewage discharge grooves 14 is arranged on the inner wall of the fixed column 7.

[0040] When the scraping plate 12 rotates, it will drive the extrusion block 13 to rotate synchronously, so that the extrusion block 13 extrudes the force-bearing block 17. Under the action of the force, the force-bearing block 17 pushes the first limiting plate 15 to slide downward on the surface of the water delivery sleeve 6 and extrudes the first limiting spring 16. When the force-bearing block 17 enters the inside of the groove 18 downward, the limit on the sewage discharge groove 14 can be completely released. At this time, the scraping plate 12 continues to rotate, scraping the filtered particulate matter and a part of the sewage into the inside of the sewage discharge groove 14. At this time, the particulate matter and the sewage fall and pass through the channel 19 on the inner wall of the fixed column 7 and enter the inside of the sewage collection box 2. After the scraping plate 12 is separated from the force-bearing block 17, the first limiting spring 16 acts under the force to push the first limiting plate 15 to reset and re-limit the sewage discharge groove 14 to prevent the sewage from continuously entering the inside of the sewage discharge groove 14.

[0041] Please refer to Figure 7 、 Figure 8 、 Figure 9 、 Figure 12 and Figure 13 Figure, the aeration mechanism includes an air storage tank 24 installed at the top end of the water delivery sleeve 6. An air inlet 25 adapted to the air storage tank 24 is provided on the outer wall of the top end of the tank body 1. A first filter screen 26 is fixedly connected to the inner wall of one end of the air inlet 25. A first spring piece 27 is fixedly connected to the inner wall of the top end of the tank body 1. A first baffle 28 adapted to the air inlet 25 is provided on the outer wall of one end of the first spring piece 27. A piston block 29 is slidably connected to the inner wall of the air storage tank 24. A connecting spring 30 adapted to the piston block 29 is provided on the inner wall of the air storage tank 24. An air inlet groove 31 is opened on the outer wall of the piston block 29. A second limiting spring 32 is fixedly connected to the inner wall of the air inlet groove 31. A connecting plate 33 is fixedly connected to the outer wall of one end of the second limiting spring 32. A plurality of groups of slits 34 are opened on the outer peripheral edge of the connecting plate 33 in the circumferential direction. A limiting ring 35 adapted to the slits 34 is provided on the inner wall of the air inlet groove 31. An extrusion plate 36 adapted to the piston block 29 is provided on the outer wall of the top end of the connecting shaft 20. A through groove 37 is opened on the inner wall of the connecting shaft 20. A connecting column 38 is fixedly connected to the bottom outlet of the through groove 37. A plurality of groups of fine ventilation grooves 39 are opened on the outer wall of the connecting column 38. A plurality of groups of fixing blocks 40 are distributed at fixed intervals on the inner wall of the ventilation groove 39. An air vent 41 is opened on the outer wall of the fixing block 40. A limiting spring piece 42 adapted to the air vent 41 is provided on the outer wall of the fixing block 40. A pressure sensor 43 is installed on the inner wall of the tank body 1. An exhaust port 44 is opened on the outer wall of the tank body 1. A water blocking plate 58 is fixedly connected to the inner wall of the top end of the water delivery sleeve 6.

[0042] When the connecting shaft 20 rotates, it drives the top of the extrusion plate 36 to rotate. When the extrusion plate 36 rotates towards the piston block 29, it pushes the piston block 29 to slide inside the air storage tank 24 and compresses the connecting spring 30. When the piston block 29 slides inside the air storage tank 24, it compresses the air inside the air storage tank 24, causing the air inside the air storage tank 24 to push the connecting plate 33 to slide inside the air inlet groove 31 and compress the second limiting spring 32, separating the connecting plate 33 from the limiting ring 35 and releasing the limitation on the notch 34, enabling the air inside the air storage tank 24 to enter the inside of the water delivery sleeve 6 through the air inlet groove 31. After the extrusion plate 36 separates from the piston block 29, the connecting spring 30 under the action of force pushes the piston block 29 to reset. At the same time, the second limiting spring 32 under the action of force pushes the connecting plate 33 to reset, causing the limiting ring 35 to limit the notch 34 again, enabling the piston block 29 to compress the air inside the water delivery sleeve 6 and squeeze it into the inside of the through groove 37. At the same time, the reset of the piston block 29 will generate a suction force in the air storage tank 24, causing the external air to pass through the first filter screen 26 and enter the inside of the air inlet 25 and exert a thrust force on the surface of the first baffle 28, causing the first spring piece 27 to drive the first baffle 28 to rotate and release the limitation on the air inlet 25. The air that enters the inside of the through groove 37 will enter the inside of the sewage through multiple ventilation grooves 39 on the surface of the connecting column 38 and aerate the sewage. During this process, the air will sequentially pass through the ventilation openings 41 on the surfaces of multiple fixing blocks 40 inside the ventilation grooves 39 and push the limiting spring piece 42 to rotate, thereby releasing the limitation on the ventilation openings 41, dispersing the air into countless tiny bubbles and entering the inside of the sewage, thus improving the aeration effect on the sewage. At the same time, due to the small diameter of the ventilation grooves 39 and the cooperation of the limiting spring piece 42 to limit the ventilation openings 41, it can effectively prevent the sewage from flowing into the inside of the through groove 37. At the same time, the air pressure sensor 43 can monitor the air pressure inside the tank body 1 in real time and cooperate with the exhaust port 44 to ensure the stability of the air pressure inside the tank body 1. By setting the water blocking plate 58, it can prevent the sewage inside the water delivery sleeve 6 from entering the inside of the air storage tank 24.

[0043] Please refer to Figure 2 and Figure 10, the pumping mechanism includes a pumping sleeve 45 installed on the inner wall of the tank body 1 and adapted to the sewage collection tank 2. The end of the pumping sleeve 45 extending into the interior of the sewage collection tank 2 is provided with a water inlet 46 on the outer wall. A second filter screen 47 is installed on the inner wall of the water inlet 46. A second spring piece 48 is fixedly connected to the bottom inner wall of the pumping sleeve 45. A second baffle 49 adapted to the water inlet 46 is arranged on the outer wall of one end of the second spring piece 48. A return spring 50 is fixedly connected to the bottom inner wall of the pumping sleeve 45. A piston plate 51 is fixedly connected to the outer wall of the top end of the return spring 50. A plurality of groups of water inlet holes 52 are circumferentially formed on the inner peripheral edge of the piston plate 51 in the circumferential direction. A connecting rod 53 is fixedly connected to the top surface of the piston plate 51. A second limiting plate 54 is slidably connected to one end of the connecting rod 53 close to the piston plate 51. A limiting block 55 adapted to the second limiting plate 54 is arranged on the outer wall of the connecting rod 53. A water outlet 56 is formed on the outer wall of the top end of the pumping sleeve 45. An electric induction valve 59 is installed on the bottom outer wall of the sewage collection tank 2. A sewage discharge pipe 60 is installed on the outer wall of the electric induction valve 59.

[0044] When the rotating frame 9 rotates, it will drive the pressing block 57 to rotate synchronously. When the pressing block 57 moves above the connecting rod 53, it will push the connecting rod 53 to slide into the interior of the pumping sleeve 45, thereby pushing the piston plate 51 to compress the return spring 50. At this time, the sewage below the piston plate 51 inside the pumping sleeve 45 will pass through the water inlet holes 52 and lift the second limiting plate 54 to flow above the piston plate 51, and the limiting block 55 will limit the second limiting plate 54. When the pressing block 57 is separated from the connecting rod 53, the return spring 50 under the action of force pushes the piston plate 51 to move upward. When the piston plate 51 moves upward, it will first close with the second limiting plate 54, so that the second limiting plate 54 limits the water inlet holes 52. Then the second limiting plate 54 continues to move upward, and the sewage inside the pumping sleeve 45 can be pushed out from the water outlet 56 and enter the interior of the tank body 1. During this process, the pumping sleeve 45 will generate a suction force on the interior of the sewage collection tank 2, causing the second baffle 49 to move upward and drive the second spring piece 48 to rotate, thereby releasing the limit on the water inlet 46. At this time, the sewage inside the sewage collection tank 2 will pass through the filtration of the second filter screen 47 and pass through the water inlet 46 into the interior of the pumping sleeve 45. When the piston plate 51 stops rising, the second spring piece 48 under the action of force pushes the second baffle 49 to reset and re-limit the water inlet 46. When the electric induction valve 59 detects that the sludge inside the sewage collection tank 2 is full, it will automatically open, so that the sludge inside the sewage collection tank 2 is discharged through the sewage discharge pipe 60. When the electric induction valve 59 detects that the sludge in the sewage discharge pipe 60 has turned into sewage, it will automatically close.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
