Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device that integrates flocculation and sedimentation. Background Technology

[0002] The wastewater treatment plant is equipped with a separate tank, lift pump, level control device, and chemical dosing device for each physicochemical treatment step. However, the chemical dosing device and other related equipment are prone to uneven agitation at the edges. In the sedimentation zone, sludge adheres to the inner wall of the sludge hopper at the bottom, making it difficult to discharge and affecting sludge removal efficiency. In related technologies, a utility model patent with patent publication number CN218290572U proposes an integrated wastewater treatment device with a central guide tube sedimentation system. This device includes a rectangular box and a stirring mechanism. The inner cavity of the box is equipped with partitions to form a reaction chamber, a flocculation chamber, and a sedimentation chamber. The bottom of the sedimentation chamber has a conical sedimentation tank. The reaction chamber is located at the left end of the box and its upper part is connected to the flocculation chamber. A heating pipe is installed at the bottom of the reaction chamber. A guide tube is fixedly installed inside the sedimentation chamber, located at the center of the sedimentation tank with its lower end facing the bottom of the sedimentation tank. A horizontal branch pipe is connected to the middle of the guide tube, and the other end of the branch pipe is connected to the flocculation chamber. A pneumatic diaphragm pump is connected to the bottom of the sedimentation tank via a pipe. A flange-shaped overflow weir is provided at the top of the sedimentation tank, and an overflow trough is formed between the overflow weir and the inner wall of the sedimentation chamber.

[0003] Based on the aforementioned prior art, the inventors, in conjunction with relevant technologies, discovered in practical applications that the uneven stirring at the edge of the dosing device during wastewater treatment leads to reduced sedimentation efficiency. Furthermore, the sludge in the sedimentation zone of the device adheres to the inner wall of the sludge hopper at the bottom, and the sludge easily causes blockage of the sludge discharge pipe. Therefore, manual cleaning is required, which is not only inefficient but also time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described in detail below: A wastewater treatment device integrating flocculation and sedimentation, comprising: This utility model discloses a wastewater treatment device that integrates flocculation and sedimentation, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes: a sedimentation tank 1, a sedimentation cavity 5, a dosing chamber 4, a first inlet 8, and a stirring mechanism. The sedimentation tank 1 has a sedimentation cavity 5. The dosing chamber 4 is fixedly connected to the sedimentation tank 1. The dosing chamber 4 has a first inlet 8 and a first outlet 51. The first outlet 51 is connected to the sedimentation cavity 5. The first inlet 8 is used to add wastewater to be treated. The stirring mechanism is rotatably installed in the dosing chamber 4 and includes a main stirring assembly, a transmission assembly, and a secondary stirring assembly. The secondary stirring assembly is connected to the main stirring assembly through the transmission assembly. The transmission assembly enables the main stirring assembly to drive the secondary stirring assembly to stir within the dosing chamber 4. The dosing chamber can be stirred internally by the stirring mechanism. Wastewater to be treated is injected into the first inlet 8 and, after being stirred evenly, flows into the sedimentation cavity 5 connected to it from the first outlet 51. The stirring mechanism can drive the main stirring assembly to drive the secondary stirring assembly to stir the reagent and the wastewater to be treated evenly inside the stirring chamber through the transmission assembly. In this embodiment, by adding a stirring mechanism, the rotation speed of the stirring component can be changed by adjusting the main stirring component, so that the edge of the dosing chamber 4 is stirred more evenly, thereby making the reagent and wastewater mix more quickly, laying the groundwork for the subsequent flocculation reaction. At the same time, the coordinated operation of the main stirring component and the secondary stirring component can form a multi-dimensional stirring flow field in the dosing chamber 4, avoiding the occurrence of stirring dead zones, further improving the mixing efficiency of the reagent and wastewater, and ensuring that sufficient pretreatment is completed before the water flows into the sedimentation chamber 5.

[0024] like Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, the main stirring assembly includes: a first motor 13, a main stirring rod 21, and a main stirring blade 48. The first motor 13 is fixed to the dosing chamber 4, the main stirring rod 21 is fixedly connected to the output end of the first motor 13, and the main stirring blade 48 is fixedly connected to the end of the main stirring rod 21. The secondary stirring assembly includes: a secondary stirring rod 22 and a secondary stirring blade 49. The secondary stirring rod 22 and the secondary stirring blade 49 are fixedly connected. The transmission assembly includes a first gear set 42 and a second gear set 43. The first gear set 42 is disposed on the main stirring rod 21 and is circumferentially fixed relative to the main stirring rod 21. The second gear set 43 is fixedly connected to the secondary stirring rod 22 and meshes with the first gear set 42. The secondary stirring assembly: the secondary stirring rod 22 can drive the secondary stirring blade 49. The transmission assembly: the first gear set 42 on the main stirring rod 21 can drive the second gear set 43 on the secondary stirring rod 22. In this embodiment, by adding a first gear set 42 and a second gear set 43, the first gear set 42 drives the second gear set 43, which in turn drives the main stirring assembly to drive the secondary stirring assembly. This allows the first gear set 42 to rotate synchronously with the main stirring rod 21, thereby driving the meshing second gear set 43 and the secondary stirring rod 22 to rotate. By designing the gear ratio between the first gear set 42 and the second gear set 43, the rotational speed of the secondary stirring rod 22 relative to the main stirring rod 21 can be easily adjusted. This allows the main and secondary stirring assemblies to perform stirring operations at different speeds within the dosing chamber 4, adapting to the mixing requirements of different agents and wastewater, and improving the flexibility and targeting of the stirring.

[0025] like Figure 4 , Figure 7 As shown, a support plate 44 is also provided inside the dosing chamber 4. The main stirring rod 21 and the driven stirring rod 22 are rotatably connected to the support plate 44. The first gear set 42 is rotatably set on the side of the support plate 44 away from the main stirring blade 21, and the second gear set 43 is rotatably set on the side of the support plate 44 away from the driven stirring blade 49. The support plate 44 can support the main stirring rod 21 and the driven stirring rod 22 to rotate on it. In this embodiment, by adding a support plate 44, the main stirring rod 21 and the secondary stirring rod 22 are supported, making their rotation process more stable, further ensuring the stable formation of the multi-dimensional stirring flow field, and improving the mixing effect of the reagent and wastewater.

[0026] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the stirring mechanism also includes a speed regulating component, which includes a drive component and a clamping component. An adjusting groove 20 is provided on the side wall of the main stirring rod 21 along the axial direction. The first gear set 42 includes at least two driving wheels 53, which are fixedly connected and coaxially arranged on the main stirring rod 21. The first gear set 42 is slidably connected to the adjusting groove 20. The number of teeth of each driving wheel 53 is different. The second gear set 43 includes at least two driven wheels 54, which are coaxially fixedly connected to the driven stirring rod 22 at intervals. Along the axial direction of the main stirring rod 21, the number of teeth of the driving wheels 53 decreases sequentially, and the number of teeth of the driven wheels 54 increases sequentially. The number of driving wheels 53 is the same as the number of driven wheels 54, and they mesh one by one. Under the action of the drive assembly, the clamping assembly drives the first gear set 42 to slide along the extension direction of the adjustment groove 20, so that one of the at least two drive wheels meshes with the corresponding driven wheel among the at least two driven wheels, and the stirring mechanism has at least two states with different speeds.

[0027] Drive assembly: The connecting rod 25, which is rotatably connected to the transmission through hole 50 of the outer connecting plate 26, drives the inner connecting plate 26; Clamping assembly: Driven by the inner connecting plate 27, the gear clamping block 24 is driven; It should also be noted that, under the action of the drive component, the clamping component drives the first gear set 42 to slide along the extension direction of the adjustment groove 20, so that one of the drive wheels 53 meshes with one of the driven wheels 54 that is adapted to it, and the stirring mechanism has at least two states with different speeds. In this embodiment, by adding a drive component and a clamping component, the first gear set 42 can be controlled to slide longitudinally within the adjustment groove 20. When it is necessary to switch the stirring speed of the stirring component, simply slide the locking block 33 within the locking sliding hole 34, causing the locking block 33 to press against the locking spring 32, thereby separating the locking block 33 from the locking groove 28. Then, rotate the locking handle 30, causing the locking handle 30 to drive the locking rod 29 and the outer connecting plate 27, which in turn drive the inner connecting plate 26 connected to it via the connecting rod 25. The inner connecting plate 26 drives the gear clamping block 24, and the ball bearings 23 drive the first gear set 42 to move within the adjustment groove 20. Then, the locking spring 32 resets and engages the locking block 33 with the locking groove 28, thereby making the number of teeth of the driving wheel 53 different from the number of teeth of the driven wheel 54, thus achieving the switching of the stirring speed of the stirring rod 22.

[0028] like Figure 4 , Figure 7 As shown, at least two drive wheels 53 include a first drive wheel 15 and a second drive wheel 16, wherein the number of teeth of the first drive wheel 15 is greater than the number of teeth of the second drive wheel 16; At least two driven wheels 54 include a first driven wheel 17 and a second driven wheel 18. The first driven wheel 17 has fewer teeth than the second driven wheel 18. The first driven wheel 17 is coupled with the first driving wheel 15 for transmission, and the second driven wheel 18 is coupled with the second driving wheel 16 for transmission. The stirring mechanism has a first state and a second state with different speeds. In the first state, the first driving wheel 15 meshes with the first driven wheel 17 for transmission, and the stirring rod 22 has a first rotational speed; In the second state, the second driving wheel 16 meshes with the second driven wheel 18 for transmission, and the stirring rod 22 has a second rotational speed; Drive wheel 53: By having more teeth than the second drive wheel 16, when the first drive wheel 15 meshes with the first driven wheel 17, the main stirring rod 21 on the first drive wheel 15 rotates at a speed less than the driven stirring rod 22 on the first driven wheel 17. Driven wheel 54: Because the number of teeth of the first driven wheel 17 is greater than that of the second driven wheel 18, when the second driving wheel 16 meshes with the second driven wheel 18, the rotational speed of the main stirring rod 21 on the second driving wheel 16 is less than that of the driven stirring rod 22 on the second driven wheel 18. In this embodiment, the different number of teeth on the first driven wheel 17 and the second driven wheel 18 allows the stirring assembly to switch between a first state and a second state. Since there are several driving wheels and driven wheels, there are at least two states in actual applications, thereby meeting the different speed requirements of different materials during stirring and improving the adaptability and efficiency of the stirring operation.

[0029] like Figure 4, Figure 5 , Figure 7 As shown, the gear clamp 24 is rolledly connected to the first drive wheel 15 via ball bearings 23; In this embodiment, by adding ball bearings 23, the gear clamping block 24 drives the first gear set 42 to slide more smoothly, effectively reducing the frictional resistance between the gear clamping block 24 and the first driving wheel 15, avoiding the problem of jamming or wear caused by excessive friction during sliding, thereby ensuring the stability and reliability of the wheel set switching and extending the service life of the stirring mechanism.

[0030] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, a through hole 50 is provided in the dosing chamber 4; The drive assembly includes a connecting rod 25, an inner connecting plate 26 and an outer connecting plate 27 fixed at both ends of the connecting rod 25. The connecting rod 25 is rotatably inserted through the through hole 50. The inner connecting plate 26 is hinged to the clamping assembly, and the outer connecting plate 27 is used to apply power.

[0031] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the clamping assembly includes a gear clamping block 24 and a ball bearing 23. The gear clamping block 24 is hinged to the power output end of the drive assembly and clamped on both sides of the drive wheel 53. An embedding groove is formed between the drive wheel 53 and the gear clamping block 24. The ball bearing 23 rolls in the embedding groove to roll and connect between the gear clamping block 24 and the drive wheel 53. The locking groove 28 can engage or disengage with the locking block 33 in the locking assembly to control the adjustment of the drive assembly.

[0032] In this embodiment, by adding a locking groove 28, the locking component and the locking groove 28 are separated and engaged, thereby enabling the drive component to rotate and lock, achieving stability and safety during operation.

[0033] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the stirring mechanism also includes a locking component, and a locking groove 28 is provided on the outer wall of the dosing chamber 4. The locking component is provided on the drive component, and the locking component and the locking groove 28 engage with each other.

[0034] In this embodiment, by adding a locking groove 28, the locking component and the locking groove 28 are separated and engaged, thereby enabling the drive component to rotate and lock, achieving stability and safety during operation.

The end of the locking spring 32 is fixedly connected to the side wall of the locking block 33. Locking assembly: The slidable locking block 33 slides within the locking sliding hole 34, thereby compressing the locking spring 32 and separating the locking block 33 from the locking groove 28. Then, the locking handle 30 is rotated to drive the locking rod 29, which in turn drives the drive assembly and clamping assembly to complete the adjustment. In this embodiment, by adding a locking component and a driving component, the sliding protrusion 55 causes the locking block 33 to slide within the locking sliding hole 34, thereby pressing the locking spring 32 and separating the locking block 33 from the locking groove 28. Then, rotating the locking handle 30 causes the locking handle 30 to drive the locking rod 29 and the outer connecting plate 27, which in turn drive the inner connecting plate 26 connected to it via the connecting rod 25. The inner connecting plate 26 drives the gear clamping block 24, and the ball bearing 23 drives the first gear set 42 to move within the adjusting groove 20. Then, the locking spring 32 resets and engages the locking block 33 with the locking groove 28, thereby achieving the adjustment of the first gear set 42. Preferably, the locking handle 30 is rotatably connected to the outer wall of the locking rod 29.

The sludge hopper 2 is fixedly connected to the bottom of the sedimentation tank 1. The sludge scraping mechanism includes a second motor 19 and a scraper 36. The second motor 19 is fixedly connected to the bottom of the sludge hopper 2, and the scraper 36 is fixedly connected to the output end of the second motor 19. The scraper 36 cooperates with the side wall of the sludge hopper 2. The second motor drives the scraper to rotate along the side wall of the sludge hopper. The output end of the third motor 35 of the sludge discharge mechanism drives the sludge discharge rotor 14 to drive the spiral blades 47, so that the spiral blades 47 drive the sludge to move to the sludge outlet 12 for discharge. In this embodiment, by adding a third motor 35, the output end of the third motor 35 drives the sludge discharge rotor 14 to rotate, thereby driving the spiral blades 47 to move the sludge to the sludge outlet 12.

[0038] like Figure 1 , Figure 4 , Figure 8 As shown, the sludge hopper 2 has a conical structure. The scraper 36 includes: a first plate 45 fixedly connected to the output end of the second motor 19, the first plate 45 being in contact with the bottom wall of the sludge hopper 2, and a second plate 46 fixedly connected to the end of the first plate 45 away from the second motor 19, the second plate 46 being in contact with the side wall of the sludge hopper 2.

[0041] like Figure 4 , Figure 8As shown, it also includes a tilting mechanism, which includes a tilting bucket 40 and a tilting assembly. The tilting bucket 40 is located at the bottom of the sludge discharge bin 41. The tilting assembly includes a connecting rod 38 and a tilting telescopic rod 39. The connecting rod 38 is located on both sides of the sludge discharge bin 41, with its first end connected to the sludge discharge bin 41 and its second end hinged to the tilting bucket 40. The tilting telescopic rod 39 is located on both sides of the sludge discharge bin 41, with its fixed end connected to the sludge discharge bin 41 and its telescopic end connected to the tilting bucket 40. The tilting mechanism receives the sludge discharged from the sludge outlet 12 through the tilting bucket 40, and then supports it through the cooperation of the connecting rod 38 and the tilting telescopic rod 39. The tilting assembly moves the tilting bucket 40 containing sludge on the slider 37 through the connecting rod 38 and the tilting telescopic rod 39, so that it slides on the guide rail 52, thereby adjusting it to a suitable position for dumping. In this embodiment, by adding a connecting rod 38 and a tilting telescopic rod 39, the connecting rod 38 and the tilting telescopic rod 39 drive the tilting bucket 40 to be fixed on the stable slider 37, thereby causing the tilting assembly to move on the guide rail 52, and then the sludge inside the tilting bucket 40 is poured out by the retraction of the tilting telescopic rod 39.

[0042] like Figure 4 , Figure 8 As shown, the sludge discharge bin 41 is provided with a guide rail 52 on its side wall. The tilting assembly also includes a slider 37, which is slidably connected to the guide rail 52. The first end of the connecting rod 38 and the fixed end of the tilting telescopic rod 39 are both fixedly connected to the slider 37. The tilting assembly tilts the sludge-filled hopper 40 onto the slider 37 via the connecting rod 38 and the tilting telescopic rod 39, causing it to slide on the guide rail 52, thereby adjusting it to the appropriate position for dumping. In this embodiment, by adding a slider 37, the connecting rod 38, the flip telescopic rod 39 and the slider 37 can slide stably on the guide rail 52.

[0043] like Figure 1 , Figure 2 , Figure 3 As shown, it also includes: a clear water discharge mechanism installed in the sedimentation chamber. The clear water discharge mechanism includes: an overflow weir 7, an overflow trough 6, and a central suction pipe 10. The overflow weir 7 is fixedly connected to the top of the sedimentation tank 1. A second outlet 9 is opened on the side wall of the overflow weir 7. The overflow trough 6 is attached to the inner side wall of the overflow weir 7. The central suction pipe 10 extends through the bottom of the overflow trough 6 into the sedimentation chamber 5. It is used to draw the fluid of a preset height in the sedimentation chamber 5 into the overflow trough 6 and out through the second outlet 9 of the overflow weir 7. Preferably, a buffer plate 11 is fixedly installed at the bottom of the central suction pipe 10. In this embodiment, by adding a central suction pipe 10, the central suction pipe 10 guides the clear water, so that the clear water passes through the buffer plate 11 and the flocs are not easily broken, thereby guiding the clear water to the upper layer of the overflow tank 6 to overflow the overflow weir 7, and then the clear water is discharged from the clear water outlet 9.

[0044] The implementation principle of this utility model embodiment is as follows: First, the operator injects the wastewater to be treated into the dosing chamber 4 through the first inlet 8, and then adds various agents through the flocculation device 3 connected to the dosing chamber 4, so that the agents and wastewater can be mixed together. Then, the first motor 13 is started, which drives the main stirring rod 21 to rotate through the output end, thereby driving the main stirring blade 48 to stir. This causes the first gear set 42 on the side wall of the main stirring rod 21 to rotate. Then, the drive wheel 53 in the first gear set 42 rotates, which drives the driven wheel 54 in the second gear set 43 that is meshed with it. This causes the driven wheel 54 to rotate, which drives the stirring rod 22 to drive the stirring blade 49 to stir the edge of the side wall of the dosing chamber 4. Secondly, by having a greater number of teeth on the driving wheel 53 than on the driven wheel 54, the stirring rod 22 achieves a first rotational speed. The locking block 33 can slide within the locking sliding hole 34 via the protrusion 55, causing the locking block 33 to press against the locking spring 32. This separates the locking block 33 from the locking groove 28. Then, by rotating the locking handle 30, the locking handle 30 drives the locking rod 29 and the outer connecting plate 27, which in turn drives the inner connecting plate 26 connected to it via the connecting rod 25. The inner connecting plate 26 drives the gear clamp 24, and the ball bearings 23 drive the first gear set 42 to move within the adjusting groove 20. The locking spring 32 then resets the locking block 33 and engages it with the locking groove 28, thus making the number of teeth on the driving wheel 53 less than the number of teeth on the driven wheel 54, thereby adjusting the stirring rod 22 to a second rotational speed. Next, the fully mixed wastewater and reagents enter the sedimentation chamber 5 through the first outlet 51. After sedimentation, the sludge on the inner wall of the sludge hopper 2 increases. Then, the second motor 19 is started to drive the scraper 36 through the output end, so that the first plate 45 scrapes the sludge on the bottom wall of the sludge hopper 2 and the second plate 46 scrapes the sludge on the side wall of the sludge hopper 2. Then, the third motor 35 is started to rotate the sludge discharge rod 14 and drive the spiral blade 47 to move the sludge to the sludge outlet 12. The slider 37 slides on the guide rail 52 to drive the connecting rod 38 and the tilting telescopic rod 39, and drives the tilting bucket 40 to below the sludge outlet 12. After the sludge is discharged, the slider 37 moves to the end of the guide rail 52 away from the sludge hopper 2. Then, the tilting telescopic rod 39 retracts to pour out the sludge inside the tilting bucket 40. Finally, the clear water is guided through the central suction pipe 10, so that the clear water passes through the buffer plate 11 and the flocs are not easily broken, so that the clear water is guided into the overflow tank 6, the upper layer of clear water overflows the overflow weir 7, and then the clear water is discharged from the clear water outlet 9.
