Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to an automatic device for treating sludge from sewage treatment ponds. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. In wastewater treatment, wastewater treatment ponds have become important equipment, and their function is to separate sludge, clarify the mixed liquor, concentrate it, and return the activated sludge.

[0003] When treating the sludge at the bottom of a common wastewater treatment pond, the sludge is usually broken up and agitated by a sludge-crushing mechanism such as a toothed blade or a blade. This method has low sludge crushing efficiency and cannot efficiently and evenly break up clumps of sludge. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an automatic sludge treatment device for sewage treatment ponds to solve the problems mentioned in the background. The present invention has a novel structure. Through the cooperation of the drive component and the suction component, the sludge at the bottom of the treatment pond is rotated and dispersed. At the same time, two suction cylinders extract a portion of the sludge and disperse it separately in a small space, thereby improving the treatment efficiency and uniformity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic device for treating sludge in a sewage treatment tank, comprising a tank body, the top of which is covered with a top cover, a discharge pipe fixed to one side of the tank body, and a mounting plate bolted to the bottom surface of the top cover. A driving assembly is provided at the bottom center of the mounting plate, the driving assembly including a rotating shaft, two sets of bottom stirring plates fixed to the bottom surface of the rotating shaft, and two sets of stirring frames symmetrically arranged on the surface of the rotating shaft. A separating assembly is provided around the rotating shaft, the separating assembly including a bottom ring. A circular notch is provided at the center of the ring, and grooves are provided at equal intervals on the surface of the bottom ring. The surface of the grooves is covered with a cover plate, and one end of the cover plate is rotatably connected to the outer edge of the bottom ring. A suction assembly is provided at the circular notch of the bottom ring. The suction assembly includes a semi-circular plate. Two semi-circular plates are spliced ​​and installed at the bottom of the circular notch of the bottom ring. A processing cylinder is slidably installed at the bottom of the semi-circular plate. A bottom plate is provided at the lower end of the processing cylinder, and a pressure plate is slidably installed inside the processing cylinder. A connecting shaft slides through the center of the pressure plate, and the bottom of the connecting shaft is fixedly connected to the bottom plate.

[0006] Furthermore, the drive assembly also includes a drive motor. The drive motor is fixedly mounted on the top of the rotating shaft on the mounting plate, and the output end of the drive motor is fixedly connected to the rotating shaft. Two sliding grooves are equidistantly formed on the surface of the rotating shaft, and a stirring frame is slidably connected inside the sliding grooves.

[0007] Furthermore, a contact plate is fixed at the bottom of the stirring frame, and the contact plate is in pressure contact with the surface of the bottom ring. A moving groove is provided between the two semicircular plates, and the stirring frame can pass through the moving groove.

[0008] Furthermore, the separating component also includes a top ring, the top of the bottom ring is provided with a top ring, and multiple sliding rods are fixed at equal intervals between the top ring and the bottom ring, and a movable ring is slidably sleeved on the surface of the sliding rod. The bottom of the movable ring is rotatably mounted with a connecting rod through a rotating shaft, and the other end of the connecting rod is rotatably connected to the back of the cover plate through the rotating shaft.

[0009] Furthermore, three sets of first electric push rods are fixed at equal intervals at the bottom of the mounting plate, and the extended ends of the first electric push rods are fixedly connected to the bottom ring. Three sets of second electric push rods are fixed on the surface of the top ring, and the extended ends of the second electric push rods are fixedly connected to the moving ring.

[0010] Furthermore, the suction assembly also includes a third electric push rod. The third electric push rod is provided at the bottom of the mounting plate corresponding to the positions of the two semicircular plates, and the extended end of the third electric push rod is fixedly connected to the top of the semicircular plate. A rotating ring is rotatably mounted on the surface of the mounting plate, and the top of the third electric push rod is fixed on the rotating ring.

[0011] Furthermore, an extension plate is slidably inserted into the surface of the semi-circular plate, the processing cylinder is fixedly connected to the extension plate, and a fourth electric push rod is fixedly fixed to the top of the extension plate, the extended end of the fourth electric push rod being fixedly connected to the connecting shaft.

[0012] Furthermore, a fifth electric push rod is fixed on the top inner wall of the processing cylinder, and the extended end of the fifth electric push rod is fixedly connected to the pressure plate. The pressure plate has a water inlet hole on its surface. A cutter holder is slidably engaged on the surface of the connecting shaft located between the pressure plate and the bottom plate, and the bottom of the pressure plate is rotatably connected to the cutter holder. A motor is installed at the connection between the fourth electric push rod and the connecting shaft.

[0013] Furthermore, the rotating shaft has hollowed-out grooves on both sides perpendicular to the slide groove, and a sixth electric push rod is fixed inside the hollowed-out grooves facing the two processing cylinders. The extended end of the sixth electric push rod is fixedly connected to the processing cylinder.

[0014] Furthermore, a suction tube is installed on the surface of the protruding plate, and one end of the suction tube extends into the interior of the processing cylinder.

[0015] The beneficial effects of this invention are:

[0016] 1. This invention uses a drive motor to rotate a rotating shaft, and a bottom stirring plate to agitate the sludge at the bottom of the pool. When the separating component is located at the bottom of the pool, the stirring frame slides along the chute to the bottommost position, and together with the bottom stirring plate, it agitates the sludge layer to perform conventional treatment and disperses large pieces of sludge.

[0017] 2. When sludge treatment is required, the first electric push rod drives the bottom ring to rise to the position where the sludge is layered. The second electric push rod drives the moving ring to descend, and the connecting rod pushes the cover plate to rotate and cover the trough. Together with the semi-circular plate, they form a circular plate structure, which minimizes the impact of the sludge being stirred at the bottom of the pool on the turbidity of the upper water. The stirring frame is located between the two cover plates, so it does not affect the rotation of the cover plates. When the bottom ring moves, the sludge can pass through the trough, which also indirectly stirs and disperses the sludge. The bottom ring can also clean the inner wall of the pool.

[0018] 3. The treatment cylinder of the needle of the present invention is slidably inserted into the semi-circular plate through the extension plate. The two treatment cylinders can be moved horizontally by the sixth electric push rods on both sides of the rotating shaft. Because the separation component is located at the upper end of the semi-circular plate when treating sludge, the extension plate can slide out at this time without movement interference. The position of the two treatment cylinders is changed by the sixth electric push rod. In combination with the rotation of the rotating shaft, the treatment cylinders can extract sludge from multiple positions at the bottom of the pool and treat it separately. The semi-circular plate can be moved upward by the third electric push rod, thereby moving the treatment cylinder away from the bottom of the pool, which facilitates the subsequent conventional stirring work of the bottom of the pool by the stirring frame and the bottom stirring plate.

[0019] 4. During the retraction of the connecting shaft driven by the fourth electric push rod, the bottom plate moves upward, while the fifth electric push rod drives the pressure plate upward. The sludge is pushed into the treatment cylinder by the bottom plate. Then, through the rotation of the cutter frame, the sludge inside the treatment cylinder is individually dispersed relative to that in the pool, which is more efficient and has a better dispersion effect. Then, the fifth electric push rod drives the pressure plate downward to compress the space inside the treatment cylinder, dewatering the sludge. The sludge flows into the upper layer of the treatment cylinder through the water inlet hole of the pressure plate. With the cooperation of a small suction pump and suction pipe, the water after dewatering the sludge is sent to the upper layer of the separator component.

[0020] 5. Compared with the prior art, the present invention, through the cooperation of the drive component and the suction component, rotates and disperses the sludge at the bottom of the treatment tank, while two suction cylinders extract part of the sludge and disperse it separately in a small space, thereby improving the treatment efficiency and uniformity.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Please see Figures 1 to 8This invention provides a technical solution: an automatic device for treating sludge in a sewage treatment tank, comprising a tank body 1, a top cover 11 covering the top of the tank body 1, a discharge pipe 12 fixed to one side of the tank body 1, and a mounting plate 13 bolted to the bottom surface of the top cover 11. A drive assembly 4 is provided at the bottom center of the mounting plate 13. The drive assembly 4 includes a rotating shaft 42, two sets of bottom stirring plates 43 fixed to the bottom surface of the rotating shaft 42, and two sets of stirring frames 45 symmetrically arranged on the surface of the rotating shaft 42. A separating assembly 2 is provided around the rotating shaft 42, the separating assembly 2 including a bottom ring 21. A circular notch is provided at the center of the bottom ring 21, and equidistant grooves 22 are provided on the surface of the bottom ring 21. A cover plate 23 covers the surface of the grooves 22, and one end of the cover plate 23 is rotatably connected to the outer edge of the bottom ring 21. A suction component 3 is provided at the circular notch of the bottom ring 21. The suction component 3 includes a semi-circular plate 31. Two semi-circular plates 31 are spliced ​​and installed at the bottom of the circular notch of the bottom ring 21. A processing cylinder 34 is slidably installed at the bottom of the semi-circular plate 31. A bottom plate 36 is provided at the lower end of the processing cylinder 34. A pressure plate 312 is slidably installed inside the processing cylinder 34. A connecting shaft 310 slides through the center of the pressure plate 312. The bottom of the connecting shaft 310 is fixedly connected to the bottom plate 36. When using the device, the drive component 4, the separator component 2 and the suction component 3 are all installed on the mounting plate 13. They can be directly disassembled when not in use. The drive component 4 initially disperses the sludge layer at the bottom of the pool 1. The separator component 2 separates the sludge and water layers. The suction component 3 independently suctions and disperses the sludge layer, improving the efficiency of treating large pieces of sludge.

[0032] In this embodiment, the drive assembly 4 further includes a drive motor 41. The drive motor 41 is fixedly mounted on the top of the rotating shaft 42 on the mounting plate 13, and the output end of the drive motor 41 is fixedly connected to the rotating shaft 42. Two sliding grooves 44 are equidistantly opened on the surface of the rotating shaft 42, and a stirring frame 45 is slidably connected inside the sliding grooves 44. A contact plate 46 is fixed at the bottom of the stirring frame 45, and the contact plate 46 is in pressure contact with the surface of the bottom ring 21. A moving groove 32 is provided between the two semi-circular plates 31, and the stirring frame 45 can pass through the moving groove 32. The drive motor 41 drives the rotating shaft 42 to rotate, and the bottom stirring plate 43 stirs the sludge at the bottom of the pool 1. When the separating assembly 2 is located at the bottom of the pool 1, the stirring frame 45 slides along the sliding groove 44 to the bottommost position, and together with the bottom stirring plate 43, stirs the sludge layer to perform conventional treatment and disperses large pieces of sludge.

[0033] In this embodiment, the separating component 2 further includes a top ring 27. The top ring 27 is provided on the top of the bottom ring 21, and multiple sliding rods 28 are fixed at equal intervals between the top ring 27 and the bottom ring 21. A movable ring 25 is slidably sleeved on the surface of each sliding rod 28. A connecting rod 24 is rotatably mounted on the bottom of the movable ring 25 via a rotating shaft, and the other end of the connecting rod 24 is rotatably connected to the back of the cover plate 23 via the rotating shaft. Three sets of first electric push rods 26 are fixed at equal intervals on the bottom of the mounting plate 13, and the extended ends of the first electric push rods 26 are fixedly connected to the bottom ring 21. Three sets of second electric push rods 29 are fixed on the surface of the top ring 27, and the extended ends of the second electric push rods 29 are fixedly connected to the movable ring 25. Separating component 2 When located at the bottom of the pool 1, the cover plate 23 is in a vertically open state. When sludge needs to be treated, the first electric push rod 26 drives the bottom ring 21 to rise to the position where the sludge is layered. The second electric push rod 29 drives the moving ring 25 to descend. The connecting rod 24 pushes the cover plate 23 to rotate and cover the trough 22, which together with the semi-circular plate 31 forms a circular plate structure. This minimizes the impact of stirring the sludge at the bottom of the pool 1 on the turbidity of the upper water. The stirring frame 45 is located between the two cover plates 23, so it will not affect the rotation of the cover plate 23. When the bottom ring 21 moves, the sludge can pass through the trough 22, which also indirectly stirs the sludge. The bottom ring 21 can also clean the inner wall of the pool 1.

[0034] In this embodiment, the suction assembly 3 further includes a third electric push rod 33. The third electric push rod 33 is positioned at the bottom of the mounting plate 13 corresponding to the positions of the two semicircular plates 31, and its extended end is fixedly connected to the top of the semicircular plates 31. A rotating ring 14 is rotatably mounted on the surface of the mounting plate 13, and the top of the third electric push rod 33 is fixed to the rotating ring 14. An extension plate 38 is slidably inserted into the surface of the semicircular plates 31. The processing cylinder 34 is fixedly connected to the extension plate 38, and a fourth electric push rod is fixed to the top of the extension plate 38. The fourth electric push rod 35 has its extended end fixedly connected to the connecting shaft 310. The rotating shaft 42 has hollowed-out grooves 314 on both sides perpendicular to the sliding groove 44. A sixth electric push rod 313 is fixed inside the hollowed-out grooves 314, facing the two processing cylinders 34. The extended end of the sixth electric push rod 313 is fixedly connected to the processing cylinder 34. The processing cylinder 34 is slidably inserted into the semi-circular plate 31 via an extension plate 38. The sixth electric push rods 313 on both sides of the rotating shaft 42 can push the two processing cylinders 34 to translate. When sludge is being removed, the separator 2 is located at the upper end of the semicircular plate 31, so the extension plate 38 can slide out without interference. The positions of the two treatment cylinders 34 are changed by the sixth electric push rod 313, and in conjunction with the rotation of the rotating shaft 42, the treatment cylinders 34 can extract and process sludge from multiple locations at the bottom of the tank 1 individually. The third electric push rod 33 can move the semicircular plate 31 upwards, thus moving the treatment cylinders 34 away from the bottom of the tank 1, facilitating subsequent conventional agitation of the bottom of the tank 1 using the stirring frame 45 and the bottom stirring plate 43. When the rotating shaft 42 rotates, the third electric push rod 33 rotates in conjunction with the rotating ring 14. When the processing cylinder 34 moves up and down, the sixth electric push rod 313 slides along the hollow groove 314 to avoid movement interference. The cutter holder 37 and the connecting shaft 310 are in a common sliding snap-fit ​​connection. The motor at the bottom of the fourth electric push rod 35 drives the connecting shaft 310 to rotate, which can drive the cutter holder 37 to rotate. Moreover, the connection between the cutter holder 37 and the pressure plate 312 is also a conventional shaft and collar rotation connection, which makes it easy to adjust the position of the cutter holder 37 by adjusting the position of the pressure plate 312.

[0035] In this embodiment, a fifth electric push rod 311 is fixed on the top inner wall of the processing cylinder 34, and the extended end of the fifth electric push rod 311 is fixedly connected to the pressure plate 312. The pressure plate 312 has a water inlet hole on its surface. A cutter holder 37 is slidably engaged on the surface of the connecting shaft 310 located between the pressure plate 312 and the bottom plate 36, and the bottom of the pressure plate 312 is rotatably connected to the cutter holder 37. A motor is installed at the connection point between the fourth electric push rod 35 and the connecting shaft 310. A suction pipe 39 is installed on the surface of the extension plate 38, and one end of the suction pipe 39 penetrates into the processing cylinder 34. The fourth electric push rod 35 drives the connecting shaft 310 to retract. During the process, the bottom plate 36 moves upward, and at the same time, the fifth electric push rod 311 drives the pressure plate 312 to move upward. The sludge is pushed into the treatment cylinder 34 by the bottom plate 36. Then, through the rotation of the cutter frame 37, the sludge inside the treatment cylinder 34 is separately dispersed relative to the sludge in the pool 1, which is more efficient and has a better dispersion effect. Then, the fifth electric push rod 311 drives the pressure plate 312 to move downward, compressing the space inside the treatment cylinder 34 and dewatering the sludge. The sludge flows into the upper layer of the treatment cylinder 34 through the water inlet hole of the pressure plate 312. Through the cooperation of a small suction pump and suction pipe 39, the water after the sludge is dewatered is sent to the upper layer of the separator component 2.

[0036] When using the device, the drive assembly 4, the separator assembly 2, and the suction assembly 3 are all mounted on the mounting plate 13 and can be directly disassembled when not in use. The drive motor 41 drives the rotating shaft 42 to rotate, and the bottom stirring plate 43 stirs the sludge at the bottom of the pool 1. When the separator assembly 2 is at the bottom of the pool 1, the stirring frame 45 slides along the slide groove 44 to the bottommost position, working together with the bottom stirring plate 43 to stir the sludge layer and perform routine treatment, breaking up large pieces of sludge. When the separator assembly 2 is at the bottom of the pool 1, the cover plate 23 is in a vertically open state. When sludge treatment is required, the first electric push rod 26 drives the bottom ring 21 to rise to the position of sludge stratification, and the second electric push rod 29 drives the moving ring 25 to descend. The connecting rod 24 pushes the cover plate 23 to rotate and cover the trough 22, merging with the semi-circular plate 31 to form a circular plate structure. This minimizes the impact on the turbidity of the upper water when the sludge is dispersed at the bottom of the pool 1. The stirring frame 45 is located between the two cover plates 23, so it does not affect the rotation of the cover plates 23. When the bottom ring 21 moves, the sludge can pass through the trough 22, which also indirectly disperses the sludge. The bottom ring 21 can also clean the inner wall of the pool 1. The treatment cylinder 34 is slidably inserted into the semi-circular plate 31 through the extension plate 38. The two treatment cylinders 34 can be moved horizontally by the sixth electric push rods 313 on both sides of the rotating shaft 42. Because when treating sludge, the separating component 2 is located on the semi-circular plate 31. At the top, the extension plate 38 can slide out without interference. The sixth electric push rod 313 changes the position of the two treatment cylinders 34, and in conjunction with the rotation of the rotating shaft 42, the treatment cylinders 34 can extract and separately process sludge from multiple locations at the bottom of the pool 1. The third electric push rod 33 can move the semi-circular plate 31 upwards, thus moving the treatment cylinders 34 away from the bottom of the pool 1, facilitating subsequent routine agitation of the bottom of the pool 1 using the stirring frame 45 and the bottom stirring plate 43. When the rotating shaft 42 rotates, the third electric push rod 33 rotates in conjunction with the rotating ring 14. When the treatment cylinders 34 move up and down, the sixth electric push rod 313 slides along the hollow groove 314 to avoid interference. As the fourth electric push rod 35 drives the connecting shaft 310 to retract, the bottom plate 36 moves upward. At the same time, the fifth electric push rod 311 drives the pressure plate 312 to move upward. The sludge is pushed into the treatment cylinder 34 by the bottom plate 36. Then, through the rotation of the cutter frame 37, the sludge inside the treatment cylinder 34 is separately dispersed relative to the sludge in the pool 1, which is more efficient and has a better dispersion effect. Then, the fifth electric push rod 311 drives the pressure plate 312 to move downward, compressing the space inside the treatment cylinder 34 and dewatering the sludge. The sludge flows into the upper layer of the treatment cylinder 34 through the water inlet hole of the pressure plate 312. With the cooperation of a small suction pump and suction pipe 39, the water after dewatering the sludge is sent to the upper layer of the separator component 2.

[0037] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
