Description

Technical Field

[0001] This invention relates to the field of urban wastewater treatment technology, specifically to an automated urban wastewater treatment device. Background Technology

[0002] Urban sewage is all drainage collected through sewer pipes. It is a mixture of various domestic sewage, industrial wastewater, and urban rainwater runoff discharged into the sewer system.

[0003] Most existing automated urban sewage treatment equipment involves injecting sewage into the treatment unit, turning on the power after injection, and then performing centralized filtration. During this process, due to the large volume of sewage injected, even if sewage is continued to be injected, the sewage that has begun to settle at the bottom will not flow excessively. At the start of filtration, the large amount of sludge deposited on the filter plate blocks the filter holes, reducing the filtration efficiency. In order to improve the filtration effect, the filter box needs to be cleaned after each filtration to remove the sludge inside the filter box before the next filtration can be carried out. Continuous filtration cannot be carried out, resulting in a low filtration speed. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing automated urban sewage treatment equipment, which typically involves injecting sewage into the treatment device, turning on the power for centralized filtration after injection, and then addressing the issues of excessive sewage volume leading to insufficient flow of the sediment at the bottom, reduced filtration efficiency due to the large amount of sludge deposited on the filter plates blocking the filter holes, and the need for cleaning the filter box after each filtration cycle to remove sludge before the next cycle.

[0006] As a further embodiment of the present invention: the sewage conveying mechanism includes a sewage storage chamber, which is located at one end of the inner side of the protective box and is fixedly connected to that end. A splash guard is fixedly connected to the top of the sewage storage chamber. A push plate is fixedly and rotatably connected to the middle of one side of the splash guard.

[0007] As a further embodiment of the present invention: a sealed transfer chamber is fixedly connected between the bottom end of the V-shaped partition, one end of the air extraction chamber and the bottom end of the inner side of the filter chamber, and a third filter screen is fixedly connected to both ends of the top of the fixed filter table.

[0008] As a further embodiment of the present invention: the middle part of one side of the trapezoidal gear is meshed with the bottom end of one side of the third double-headed trapezoidal gear rod, and the top view of the arc-shaped tooth block plate is a fan shape with an angle of fifteen degrees.

[0009] As a further embodiment of the present invention: a diversion arc block is fixedly connected to one end of the sewage conveying scoop plate, a clamping rod is fixedly connected to the outer side of one side of the pushing plate, and U-shaped grooves are fixedly connected to the four quadrant points of the connecting clamping plate.

[0010] As a further embodiment of the present invention: four fan blades are fixedly connected to the middle of the outer side of the pumping fan rod, a pumping chamber is fixedly connected to one side of the sealing partition, and a pulley block is rotatably connected to the outer side of the sewage conveying scoop plate where it meets the inner wall of the sewage storage chamber.

[0011] Compared with the prior art, the beneficial effects of the present invention are: it facilitates sludge discharge while performing secondary filtration of sewage, facilitates rapid filtration of sewage containing a large amount of sludge, facilitates brushing and scraping the filter plate while performing secondary filtration of sewage, which helps to improve the speed and efficiency of sewage filtration, improves the filtration effect, facilitates preliminary filtration of sewage while injecting sewage into the device, and facilitates the transportation of the pre-filtered sewage, which helps to improve the efficiency of sewage filtration.

[0012] 1. By setting up a sewage treatment mechanism, during use, when the arc-shaped toothed plate rotates and moves onto the gear disk along with the fan blade, it drives the gear disk to rotate, causing the positioning shaft fixedly connected to the bottom center of the gear disk and the push plate fixedly connected to the outside of the positioning shaft to rotate intermittently and slowly. During this process, the sewage conveying scoop plate continuously conveys sewage into the sealing chamber. When the push plate rotates slowly by ninety degrees, sewage can be conveyed to the next sealing chamber. When the sealing chamber that has been conveyed with sewage moves to the first filter screen, the air pressure generated by the constantly rotating fan blade in the air extraction chamber extracts the sewage with a large amount of residual sludge after the initial filtration, thus... Wastewater can quickly penetrate into the quartz sand filter layer, where it traps the incoming sludge. The wastewater passes through the quartz sand filter layer and enters a sealed transfer chamber fixedly connected to one side of the bottom of the filter chamber by a V-shaped partition. It then enters the activated carbon filter layer fixedly connected to the top of the water storage tank through a first flow hole fixedly connected to one end of the sealed transfer chamber and a second flow hole fixedly connected to the bottom of the suction chamber. After filtration, the wastewater enters the water storage tank. When the pusher plate rotates to the bottom of the pusher block, the pusher block drives the shrinkage rod to slide down along the shrinkage lifting chamber, pushing the scraper plate to adhere to the surface of the fixed filter table. When the fixed filter table and the pusher plate... When the sealed cavity formed by the positioning shaft moves, the moving push plate drives the scraper plate to move slowly. As the scraper plate moves, the roller brush washes the sludge on the fixed filter table, and the scraper scrapes off the residual dirt on the fixed filter table. After the sewage in the sealed cavity is filtered clean by the air extraction chamber, it is pushed by the push plate to the discharge port fixedly connected to the other side of the fixed filter table by the intermittent rotation of the gear plate. When the push plate moves to the discharge port, it simultaneously drives the top of the shrinkage pressure rod slidably connected in the middle of the push plate to separate from the push block. After the pressure is lost, the rebound force of the return spring quickly drives the shrinkage pressure rod along the shrinkage path. The lifting chamber slides back to its original position. The collision force generated during the sliding back process causes the scraper plate to vibrate, shaking off the sludge adhering to the roller brush rod and scraper plate. When the sludge is pushed to the discharge port, it falls into the sludge collection tank under the action of gravity. The motor drives the fan blade rod to rotate, which in turn drives the trapezoidal gear and arc-shaped toothed plate fixed to the outside of the fan blade rod to rotate. This facilitates sludge discharge while performing secondary filtration of sewage, and facilitates rapid filtration of sewage containing a large amount of sludge. It also facilitates brushing and scraping the filter plate while performing secondary filtration of sewage, which helps to improve the speed and efficiency of sewage filtration.

[0013] 2. By setting up a sewage conveying mechanism, the motor drives the fan blade rod to rotate, which in turn drives the trapezoidal gear and arc-shaped toothed plate fixedly connected to the outside of the fan blade rod to rotate. The rotating trapezoidal gear synchronously drives the third double-headed trapezoidal gear rod, which is meshed with the top of one side of the rotating trapezoidal gear rod, the second double-headed trapezoidal gear rod, which is meshed with the top of one side of the third double-headed trapezoidal gear rod, and the first double-headed trapezoidal gear rod, which is meshed with the top of one end of the second double-headed trapezoidal gear rod, to rotate the pumping fan rod, which is meshed with one side of one end of the first double-headed trapezoidal gear rod. The suction force generated by the rotation drives the sewage through the sewage inlet. The water is drawn into the pumping chamber where the pumping fan rod is located. It then enters the wastewater storage chamber through an outlet fixedly connected to the bottom of one side of the pumping chamber, forming a clamping cavity between a set of wastewater conveying scoops and the wall of one end of the filter chamber. As it flows into this cavity, water in the wastewater, under the influence of the arc-shaped guide block connected to the outer side of the wastewater conveying scoops, passes through the second filter screen fixedly connected to the top of the wall of one end of the filter chamber, flowing to the bottom of the inner side of the filter chamber for initial filtration. As the pumping fan rod rotates, a pusher plate fixedly connected to one side moves to a position where a pusher plate is fixedly connected to... When the lever engages with the slot on the connecting plate rotatably connected to one end of the push plate, it pushes the drive rack to rotate. This, in turn, causes the connecting chain belt, which meshes with the drive rack, to move the wastewater conveying scoop plate fixedly connected to it. When the wastewater conveying scoop plate reaches the position of the positioning rack, the pre-filtered wastewater flows through the open cavity to the bottom of the wastewater storage tank. The connecting chain belt then continues to move the next wastewater conveying scoop plate to the bottom of the positioning rack, where it scoops up the wastewater from the bottom of the storage tank. After scooping, the process continues... The rotating toothed chain belt drives the sewage conveying scoop plate, which scoops up sewage, to the top of the inner side of the splash cover. Under the action of the arc-shaped diversion block connected to the outer side of the sewage conveying scoop plate, the sewage is accurately thrown into the feed hopper at the top of the filter chamber by the rotation of the sewage conveying scoop plate. The sewage enters the sealed cavity formed by the fixed filter table, the push plate, and the positioning shaft along the feed hopper. This facilitates the initial filtration of sewage while it is being injected into the device, and also facilitates the transportation of the pre-filtered sewage, which helps to improve the efficiency of sewage filtration.

Multiple sewage conveying scoop plates 45 are fixedly connected to the outer side of the connecting toothed chain belt 44 to drive the connecting toothed chain belt 44 to rotate and to push the incoming sewage.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 6 One end of the sewage conveying scoop plate 45 is fixedly connected to a flow-guiding arc block, and a clamping rod is fixedly connected to the outer side of one side of the push plate 48. U-shaped grooves are fixedly connected to the four quadrant points of the connecting plate 47.

[0023] Please refer to this carefully. Figure 1 , Figure 2 and Figure 6 Four fan blades are fixedly connected to the middle of the outer side of the pumping fan rod 49. A pumping chamber is fixedly connected to one side of the sealing partition 413. A pulley block is rotatably connected to the outer side of the sewage conveying scoop plate 45 where it meets the inner wall of the sewage storage tank 41.

[0024] The working principle of this invention is as follows: During use, the motor 311 drives the fan blade rod 320 to rotate, simultaneously driving the trapezoidal gear 324 and the arc-shaped toothed plate 310 fixedly connected to the outside of the fan blade rod 320 to rotate. The rotating trapezoidal gear 324 synchronously drives the third double-headed trapezoidal gear rod 412 (meshing at one end), the second double-headed trapezoidal gear rod 411 (meshing at one end of one side of the third double-headed trapezoidal gear rod 412), and the first double-headed trapezoidal gear rod 410 (meshing at one end of the second double-headed trapezoidal gear rod 411) to rotate the pumping fan rod 49 (meshing at one side of one end of the first double-headed trapezoidal gear rod 410). The suction generated by the rotation draws sewage through the sewage inlet into the pumping chamber where the pumping fan rod 49 is located. The water outlet, fixedly connected to the bottom of one side of the water chamber, enters the sewage storage chamber 41 and the cavity formed by a set of sewage conveying scoop plates 45 and the wall of one end of the filter chamber 31. As the water flows into the cavity, it passes through the second filter screen 321 fixedly connected to the top of the wall of one end of the filter chamber 31 and flows to the bottom of the inner side of the filter chamber 31, where the sewage undergoes preliminary filtration. When the push plate 48, fixedly connected to one side of the pumping fan rod 49, rotates with the pumping fan rod 49, it moves to the slot on the connecting plate 47, which is rotatably connected to one end of the push plate 48. This pushes the drive rack 43 to rotate, causing it to rotate. The connecting toothed chain belt 44, which meshes with the drive rack 43, drives the sewage fixedly connected to the connecting toothed chain belt 44. The conveying scoop plate 45 moves to the position of the positioning toothed rod 46. When the wastewater conveying scoop plate 45 moves to the position of the positioning toothed rod 46, the pre-filtered wastewater flows through the open clamping cavity to the bottom of the wastewater storage tank 41. The connecting toothed chain belt 44 continues to drive the next wastewater conveying scoop plate 45 to the bottom of the positioning toothed rod 46. The wastewater conveying scoop plate 45 then scoops up the wastewater at the bottom of the wastewater storage tank 41. After scooping, the continuously rotating connecting toothed chain belt 44 rotates the wastewater conveying scoop plate 45 to the top of the inner side of the splash cover 42. The wastewater conveying scoop plate 45 rotates and throws the wastewater into the feed hopper at the top of the filter chamber 31. The wastewater enters the sealed cavity formed by the fixed filter table 38, the push plate 33, and the positioning shaft 32 along the feed hopper. As the arc-shaped toothed plate 310 rotates and moves onto the gear disk 39 along with the fan blade rod 320, it drives the gear disk 39 to rotate, causing the positioning shaft rod 32, which is fixedly connected to the bottom center of the gear disk 39, and the push plate 33, which is fixedly connected to the outside of the positioning shaft rod 32, to rotate slowly and intermittently. During this process, the sewage conveying scoop plate 45 continuously conveys sewage into the sealing cavity. When the push plate 33 rotates slowly by ninety degrees, sewage can be conveyed to the next sealing cavity. When the sealing cavity that has been conveyed with sewage moves onto the first filter screen 312, the air pressure formed by the constantly rotating fan blade rod 320 in the air extraction chamber 318 extracts the sewage with a large amount of residual sludge after the initial filtration, allowing the sewage to quickly penetrate into the quartz sand filter layer 313.The quartz sand filter layer 313 locks the incoming sludge. Wastewater passes through the quartz sand filter layer 313 and enters a sealed transfer chamber fixedly connected to the bottom side of the filter chamber 31 by a V-shaped partition 314. It then enters the activated carbon filter layer 317 fixedly connected to the top of the water storage tank 1 through a first flow hole 316 fixedly connected to one end of the sealed transfer chamber and a second flow hole 319 fixedly connected to the bottom end of the suction chamber 318. After filtration, it enters the water storage tank 1. When the pusher plate 33 rotates to the bottom end of the pusher block 37, the pusher block 37 drives the shrinking pressure rod 34 to slide down along the shrinking lifting chamber 35, pushing the scraper plate 36 to adhere to the surface of the top of the fixed filter table 38. When the sealed cavity groove formed by the fixed filter table 38, the pusher plate 33, and the positioning shaft 32 moves, the moving pusher plate 33 drives the scraper plate 36 to move slowly. When the scraper plate 36 moves, the roller brush rod 326 presses against the fixed filter table 38. The sludge on the fixed filter table 38 is scrubbed, and the scraper 327 scrapes away the residual sludge on the fixed filter table 38. After the sewage in the sealed cavity is filtered clean by the air extraction chamber 318, it is pushed by the pusher plate 33 to the discharge port fixedly connected to the other side of the fixed filter table 38 by the intermittent rotation of the gear disk 39. When the pusher plate 33 moves to the discharge port, it simultaneously drives the top of the shrinkage pressure rod 34 slidably connected in the middle of the pusher plate 33 to separate from the pusher block 37. After the pressure is lost, the rebound force of the return spring 325 quickly drives the shrinkage pressure rod 34 to slide back along the shrinkage lifting chamber 35. The collision force generated during the sliding reset process causes the scraper plate 36 to vibrate, shaking off the sludge adhering to the roller brush rod 326 and the scraper plate 327. When the sludge is pushed to the discharge port, it falls into the sludge collection tank 322 under the action of gravity, and the sewage can continue to be circulated.
