Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an aeration mechanism for a wastewater treatment aeration tank. Background Technology

[0002] An aeration tank is a biochemical reactor designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the designed aeration reaction conditions. Aeration tanks utilize the activated sludge process for wastewater treatment, providing a certain wastewater retention time to meet the oxygen requirements of aerobic microorganisms and ensure sufficient mixing and contact between wastewater and activated sludge. An aeration tank mainly consists of three parts: the tank body, the aeration system, and the inlet and outlet. The tank body is generally constructed of reinforced concrete and has shapes such as rectangular, square, and circular.

[0003] Most existing wastewater treatment aeration tanks use blowers to introduce air into the bottom of the tank to aerate the activated sludge and wastewater. The aeration pipes are fixed at the bottom of the tank, and the air discharged from the pipes moves vertically upward in the liquid. However, due to the weak upward force of the gas, the activated sludge and wastewater can only mix well near the air outlet. The wastewater and activated sludge in the area far from the air outlet cannot make sufficient contact, which does not achieve the ideal decontamination effect. Furthermore, the activated sludge is prone to sedimentation at the bottom of the tank, further resulting in poor wastewater treatment. In addition, the existing aeration tanks have a relatively complex structure and are cumbersome to operate, thus reducing work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an aeration mechanism for a sewage treatment aeration tank to solve the problems mentioned in the background art.

The limiting part is used to control the agitating plate to reciprocate at the bottom of the tank. An adjusting assembly is provided in the inner cavity of the tank. The adjusting assembly is connected to the aeration pipe. The adjusting assembly is used to control the aeration pipe to reciprocate at the bottom of the tank.

[0007] As a further aspect of the present invention: the agitation part includes multiple crossbars rotatably mounted in the inner cavity of the pool, the multiple crossbars being arranged in two rows and distributed relative to each other in the inner cavity of the pool, and multiple baffles being fixedly mounted on the surface of the crossbars.

[0009] As a further aspect of the present invention: the positioning part includes a base plate fixedly installed on two inner sidewalls opposite to the pool body, an arc-shaped guide rod fixedly installed on the sidewall of the base plate, a bearing block slidably installed on the surface of the guide rod, the two ends of the stirring plate being connected to the bearing block respectively, and a return spring fixedly installed on the sidewall of the base plate, the telescopic end of the return spring being sleeved on the outside of the guide rod and connected to the bearing block.

[0010] As a further aspect of the present invention: the limiting part includes multiple support rods fixedly installed on the opposite side walls of the pool body, the multiple support rods are jointly fixedly installed on an arc-shaped guide plate, the driving belt passes through the surface of the guide plate, a toothed channel is opened in the middle of the guide plate, the positioning toothed ring passes through the toothed channel, a magnetic block is fixedly installed on the outer side wall of the driving belt, and the bearing block is made of magnetic material.

[0011] As a further embodiment of the present invention: the adjustment assembly includes multiple support plates fixedly installed at the top of the pool body, a top plate fixedly installed in the middle of the support plate, a vertical rod fixedly installed on the bottom wall of the top plate, a bearing rod rotatably installed at the bottom end of the vertical rod, the end of the bearing rod away from the vertical rod being connected to the aeration pipe, and multiple connecting rods fixedly installed on the surface of the stirring plate, the end of the connecting rod away from the stirring plate being connected to the aeration pipe.

The agitator plate can ensure full contact between the activated sludge and the wastewater, effectively preventing the activated sludge from settling at the bottom of the tank and effectively improving the utilization effect of the activated sludge. This solves the problem that activated sludge easily settles at the bottom of the tank, resulting in poor wastewater treatment effect.

[0017] By coordinating the adjustment components with the agitator plate, the aeration pipes can be moved synchronously back and forth at the bottom of the tank, thus enabling comprehensive aeration of the tank's interior. This ensures that wastewater in all areas of the tank comes into full contact with the activated sludge for reaction. This solves the problem that currently, activated sludge and wastewater only mix well near the aeration outlet, while wastewater further away from the outlet does not fully contact the activated sludge, failing to achieve the desired decontamination effect.

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 7The diagram shown illustrates the structure of an aeration mechanism for a wastewater treatment aeration tank according to an embodiment of the present invention. The tank includes a tank body 1 with a semi-cylindrical bottom. An inlet pipe 11 is located on one side wall of the tank body 1, and a drain pipe 12 is located on the other side wall. An aeration pipe 2 is located at the bottom of the tank body 1, and an air inlet hose 21 is connected to the surface of the aeration pipe 2. The end of the air inlet hose 21 away from the aeration pipe 2 extends to the outside of the tank body 1 and connects to a blower. Multiple aeration holes 22 are provided on the side wall of the aeration pipe 2. A control mechanism 3 is located within the tank body 1. The control mechanism 3 includes a flow guiding component 31 and a mixing component 32. The flow guiding component 31 includes a stirring part 311 and a driving part 312. The stirring part 311 is located within the tank body 1. 311 is used to agitate the sewage inside the tank 1. The drive unit 312 is located inside the tank 1 and connected to the agitator 311. The drive unit 312 is used to control the agitator 311. The mixing assembly 32 includes an agitator 321, a positioning part 322 and a limiting part 323. The positioning part 322 is located on the inner side wall of the tank 1 and connected to the agitator 321. The positioning part 322 is used to position the agitator 321 at the bottom inside the tank 1. The limiting part 323 is located inside the tank 1 and connected to the positioning part 322. The limiting part 323 is used to control the agitator 321 to reciprocate at the bottom inside the tank 1. An adjustment assembly 4 is provided inside the tank 1. The adjustment assembly 4 is connected to the aeration pipe 2. The adjustment assembly 4 is used to control the aeration pipe 2 to reciprocate at the bottom inside the tank 1.

[0030] Wastewater is injected into the inner cavity of tank 1 through inlet pipe 11, and an appropriate amount of activated sludge is added to tank 1. During use, air is delivered to aeration pipe 2 through air inlet hose 21. The air is further discharged into the wastewater through aeration holes 22 to form bubbles. As the bubbles move upward in the wastewater, the activated sludge and wastewater can mix better, thereby improving the reaction and treatment effect of the activated sludge on the wastewater. During the aeration process, drive unit 312 and stirring unit 311 work together to stir the wastewater in the inner cavity of tank 1, keeping the wastewater in the inner cavity of tank 1 in a constant state of flow. This allows the wastewater far from the rising bubble position to fully contact the activated sludge, effectively improving the decontamination effect on the wastewater. Some activated sludge settles at the bottom of tank 1. During aeration, the positioning part 322 positions the stirring plate 321 at the bottom of tank 1. The limiting part 323 cooperates with the positioning part 322 to drive the stirring plate 321 to swing back and forth at a certain angle at the bottom of tank 1. When the stirring plate 321 swings back and forth, it can stir the activated sludge settled at the bottom of tank 1, so that the activated sludge can be continuously mixed with the sewage, avoiding the sedimentation of activated sludge at the bottom of tank 1. When the stirring plate 321 swings back and forth, the adjusting component 4 cooperates with the stirring plate 321 to control the aeration pipe 2 to swing back and forth synchronously at the bottom of tank 1. When the aeration pipe 2 swings, it can continuously change the aeration position in the inner cavity of tank 1, so that the bubbles generated by the aeration holes 22 can be evenly distributed in the inner cavity of tank 1, improving the mixing reaction effect of activated sludge and sewage in all aspects.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in a preferred embodiment of the present invention, the stirring part 311 includes a plurality of crossbars 3111 rotatably mounted in the inner cavity of the pool body 1. The plurality of crossbars 3111 are arranged in two rows and distributed opposite to each other in the inner cavity of the pool body 1. A plurality of baffles 3112 are fixedly mounted on the surface of the crossbars 3111.

[0032] During the wastewater treatment process, the drive unit 312 controls multiple crossbars 3111 to rotate around their own axis. The crossbars 3111 drive multiple baffles 3112 to rotate synchronously. The baffles 3112 can agitate the wastewater in the inner cavity of the tank body 1, so that the wastewater in the inner cavity of the tank body 1 flows fully and effectively improves the mixing effect of activated sludge and wastewater in the inner cavity of the tank body 1.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in a preferred embodiment of the present invention, the drive unit 312 includes a positioning gear plate 3121 fixedly mounted on the surface of a crossbar 3111, and a ring-shaped drive belt 3122 is mounted on the surface of multiple positioning gear plates 3121. A ring-shaped positioning gear ring 3123 is provided on the inner side wall of the drive belt 3122. The positioning gear ring 3123 meshes with the positioning gear plate 3121. A motor 3124 is fixedly mounted on the side wall of the pool body 1. The output shaft of the motor 3124 is connected to a set of crossbars 3111.

[0034] In use, the motor 3124 drives a set of crossbars 3111 to rotate around its own axis. The crossbars 3111 drive the positioning gear plate 3121 to rotate synchronously. The positioning gear plate 3121 and the positioning gear ring 3123 cooperate with each other to drive multiple crossbars 3111 to rotate synchronously around their own axis.

[0035] like Figure 2 , Figure 3 , Figure 6 As shown, in a preferred embodiment of the present invention, the positioning part 322 includes a bottom plate 3221 fixedly installed on the two inner sidewalls of the pool body 1 respectively. An arc-shaped guide rod 3222 is fixedly installed on the sidewall of the bottom plate 3221. A bearing block 3223 is slidably installed on the surface of the guide rod 3222. The two ends of the stirring plate 321 are respectively connected to the bearing block 3223. A return spring 3224 is fixedly installed on the sidewall of the bottom plate 3221. The telescopic end of the return spring 3224 is sleeved on the outside of the guide rod 3222 and connected to the bearing block 3223.

[0036] The bottom plate 3221 positions the guide rod 3222 inside the pool body 1. The guide rod 3222 positions the bearing block 3223. The two bearing blocks 3223 position the stirring plate 321 at the bottom inside the pool body 1. The return spring 3224 applies a pushing force to the bearing block 3223 on the surface of the guide rod 3222. The bearing block 3223 is located at the end of the guide rod 3222 away from the bottom plate 3221. During wastewater treatment, the limiting part 323 intermittently applies a pulling force to the bearing block 3223, thereby pulling the bearing block 3223 to move along the surface of the guide rod 3222 towards the bottom plate 3221. When the bearing block 3223 moves, it drives the stirring plate 321 to move synchronously at the bottom of the tank 1. When the bearing block 3223 moves towards the bottom plate 3221, it continuously compresses the return spring 3224. When the bearing block 3223 and the stirring plate 321 have moved a certain distance, the limiting part 323 releases the restriction on the bearing block 3223. At this time, the return spring 3224 pushes the bearing block 3223 to move back to its original position along the surface of the guide rod 3222. The bearing block 3223 drives the stirring plate 321 to move back to its original position synchronously in the opposite direction. In this cycle, the bearing block 3223 can drive the stirring plate 321 to swing back and forth at the bottom of the tank 1. When the stirring plate 321 swings back and forth, it can stir the activated sludge settled at the bottom of the tank 1, so that the activated sludge can be continuously mixed with the sewage and the activated sludge can be prevented from settling at the bottom of the tank 1.

[0037] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment of the present invention, the limiting part 323 includes a plurality of support rods 3231 fixedly installed on the opposite side walls of the pool body 1, the plurality of support rods 3231 are jointly fixedly installed on an arc-shaped guide plate 3232, the driving belt 3122 passes through the surface of the guide plate 3232, the guide plate 3232 has a toothed channel 3233 in the middle, the positioning toothed ring 3123 passes through the toothed channel 3233, the outer side wall of the driving belt 3122 is fixedly installed with a magnetic block 3234, and the bearing block 3223 is made of magnetic material.

[0038] Multiple support rods 3231 position the guide plate 3232, which in turn positions the drive belt 3122. The positioning gear ring 3123 on the surface of the drive belt 3122 is located within the gear channel 3233. In use, the motor 3124 drives a set of crossbars 3111 to rotate around their own axis. The crossbars 3111 drive the positioning gear disc 3121 and the drive belt 3122 to rotate synchronously. As the drive belt 3122 rotates, it drives the magnetic block 3234 to move synchronously. When the magnetic block 3234 moves to a position where it is in contact with the support block 3223, it is magnetically attracted to the support block 3223, forming a single unit. As the drive belt 3122 moves the magnetic block 3234, the magnetic block 3234 drives the support block 3223 to move synchronously along the surface of the guide rod 3222 towards the base plate 3221. As the support block 3223 moves toward the base plate 3221, it continuously compresses the return spring 3224. When the support block 3223 and the stirring plate 321 have moved a certain distance, the pushing force of the return spring 3224 on the support block 3223 is greater than the magnetic attraction between the magnetic block 3234 and the support block 3223. At this time, the magnetic block 3234 and the support block 3223 separate from each other, and the return spring 3224 pushes the support block 3223 to move back to its original position along the surface of the guide rod 3222.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the adjusting component 4 includes a plurality of support plates 41 fixedly installed at the top of the pool body 1, a top plate 42 fixedly installed in the middle of the support plate 41, a vertical rod 43 fixedly installed on the bottom wall of the top plate 42, a bearing rod 44 rotatably installed at the bottom end of the vertical rod 43, and the end of the bearing rod 44 away from the vertical rod 43 is connected to the aeration pipe 2. A plurality of connecting rods 45 are fixedly installed on the surface of the stirring plate 321, and the end of the connecting rod 45 away from the stirring plate 321 is connected to the aeration pipe 2.

[0040] The support plate 41 positions the top plate 42, which in turn positions the vertical rod 43. The vertical rod 43 then positions the supporting rod 44. Multiple supporting rods 44 position the aeration pipe 2 within the inner cavity of the tank body 1. The stirring plate 321 is connected to the aeration pipe 2 via multiple connecting rods 45, forming a single unit. As the stirring plate 321 reciprocates, it drives the aeration pipe 2 to rotate synchronously, automatically adjusting the aeration position within the inner cavity of the tank body 1. This ensures that the wastewater in each area of ​​the inner cavity of the tank body 1 fully contacts and reacts with the activated sludge. During the oscillation process, the multiple supporting rods 44 effectively improve the stability of the aeration pipe 2.

[0041] like Figure 6As shown, in a preferred embodiment of the present invention, a baffle 5 is fixedly installed at the end of the guide rod 3222 away from the base plate 3221.

[0042] The baffle 5 limits and protects the bearing block 3223 at the end of the guide rod 3222 to prevent the bearing block 3223 from falling off the end of the guide rod 3222.

[0043] like Figure 2 , Figure 3 , Figure 8 As shown, in a preferred embodiment of the present invention, two oppositely distributed side plates 6 are fixedly installed in the inner cavity of the pool body 1. The two side plates 6 are respectively located on both sides of the aeration pipe 2, and a perforated brush 61 is provided on the side wall of the side plate 6 facing the aeration pipe 2.

[0044] The side plate 6 positions the pore-clearing brush 61. When the aeration pipe 2 swings back and forth in the sewage, a small amount of activated sludge may clog the aeration holes 22 on the surface of the aeration pipe 2. When the aeration pipe 2 swings to its limit position, the pore-clearing brush 61 is inserted into the aeration hole 22, which can effectively clear the aeration hole 22.

[0045] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the bottom wall of the pool body 1 is provided with a guide pipe 7, and a control valve is provided on the surface of the guide pipe 7.

[0046] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the surface of the vertical rod 43 is provided with a clamping member 8, which is connected to the air inlet ointment 21.

[0047] The working principle of this invention is as follows: Wastewater is injected into the inner cavity of the tank 1 through the inlet pipe 11, and an appropriate amount of activated sludge is added to the tank 1. During use, the air inlet hose 21 delivers air to the aeration pipe 2, and the air is further discharged into the wastewater through the aeration holes 22 to form bubbles. As the bubbles move upward in the wastewater, the activated sludge and wastewater can be mixed better, thereby improving the reaction and treatment effect of the activated sludge on the wastewater. During the aeration process, the motor 3124 drives a set of crossbars 3111 to rotate around its own axis. The crossbars 3111 drive the positioning gear plate 3121 to rotate synchronously. The positioning gear plate 3121 and the positioning gear ring 3123 cooperate with each other to drive multiple crossbars 3111 to rotate synchronously around their own axes. The crossbars 3111 drive multiple baffles 3112 to rotate synchronously. The baffles 3112 can agitate the wastewater in the inner cavity of the tank 1, so that the wastewater in the inner cavity of the tank 1 flows fully, effectively improving the mixing effect of activated sludge and wastewater in the inner cavity of the tank 1.

[0048] The guide plate 3232 positions the drive belt 3122, and the positioning toothed ring 3123 on the surface of the drive belt 3122 is located within the toothed channel 3233. When the drive belt 3122 rotates, it drives the magnetic block 3234 to move synchronously. When the magnetic block 3234 moves to a position where it is in contact with the support block 3223, the magnetic block 3234 is connected to the support block 3223 as a whole by magnetic attraction. As the drive belt 3122 moves the magnetic block 3234, the magnetic block 3234 drives the support block 3223 to move synchronously along the surface of the guide rod 3222 towards the base plate 3221. As the support block 3223 moves toward the bottom plate 3221, it continuously compresses the return spring 3224. After the support block 3223 and the stirring plate 321 have moved a certain distance, the pushing force of the return spring 3224 on the support block 3223 is greater than the magnetic attraction between the magnetic block 3234 and the support block 3223. At this time, the magnetic block 3234 and the support block 3223 separate from each other, and the return spring 3224 pushes the support block 3223 to move back to its original position along the surface of the guide rod 3222. This cycle repeats, and the support block 3223 can drive the stirring plate 321 to swing back and forth at the bottom of the tank 1. When the stirring plate 321 swings back and forth, it can stir the activated sludge settled at the bottom of the tank 1, so that the activated sludge can be continuously mixed with the sewage, and the activated sludge can be prevented from settling at the bottom of the tank 1.

[0049] Multiple support rods 44 position the aeration pipe 2 within the inner cavity of the tank body 1. A stirring plate 321 is connected to the aeration pipe 2 as a whole via multiple connecting rods 45. As the stirring plate 321 oscillates back and forth, it drives the aeration pipe 2 to rotate synchronously, thereby automatically adjusting the aeration position within the inner cavity of the tank body 1. This ensures that the wastewater in each area of ​​the inner cavity of the tank body 1 fully contacts and reacts with the activated sludge. During the oscillation process, the multiple support rods 44 effectively improve the stability of the aeration pipe 2.

[0050] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
