The decentralized water inlet mechanism includes a decentralized water inlet buffer box fixedly connected to the outside of the sedimentation tank body, and multiple decentralized water inlet slots on the side wall of the sedimentation tank body that communicate with the interior of the decentralized water inlet buffer box. A decentralized water inlet overflow trough is fixed on the side of the decentralized water inlet buffer box away from the sedimentation tank body, and the decentralized water inlet overflow trough is connected to the interior of the decentralized water inlet buffer box through the decentralized water inlet overflow slots.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a backwashing type high-turbidity water sedimentation tank. Background Technology

[0002] Visually, high-turbidity wastewater is noticeably cloudy and has low transparency. This is because it contains a large amount of suspended particulate matter, which makes it difficult for light to pass through. The wastewater appears muddy, cloudy, or opaque. Since it may contain various organic and inorganic substances, in addition to being cloudy, its color is often also darker, possibly exhibiting different hues such as gray, brown, or black. The specific color depends on the source of the wastewater and the types of pollutants it contains.

[0003] Existing technologies for sedimentation treatment of high-turbidity wastewater still have some shortcomings. Because the suspended particulate matter in high-turbidity wastewater is much higher than that in general wastewater, the equipment has limited load-bearing capacity during the treatment process, which may lead to a sharp decline in effluent quality. The treatment process needs further improvement and optimization. Summary of the Invention

[0004] The purpose of this invention is to provide a backwashing type high turbidity water sedimentation tank, which can efficiently cause suspended particles in high turbidity wastewater to settle and effectively maintain the stability of the sedimentation tank's operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A backwashing type high turbidity water sedimentation tank includes a sedimentation tank body with an upward opening, a decentralized water inlet mechanism on the outside of the sedimentation tank body, and a sedimentation backwashing mechanism at the bottom of the sedimentation tank body.

[0007] The decentralized water inlet mechanism includes a decentralized water inlet buffer box that is fixedly connected to the outside of the sedimentation tank body. The side wall of the sedimentation tank body has multiple decentralized water inlet slots that communicate with the inside of the decentralized water inlet buffer box.

[0008] A decentralized water inlet buffer tank is fixed on the side away from the sedimentation tank body. The decentralized water inlet overflow trough is connected to the inside of the decentralized water inlet buffer tank through a decentralized water inlet overflow slot.

[0009] The sedimentation backwashing mechanism includes a sedimentation backwashing support block that is slidably connected to the bottom of the sedimentation tank body along the width direction. A sedimentation backwashing scraper is fixed at the lower end of the sedimentation backwashing support block. A backwashing conveying pipe is fixed on the side of the sedimentation backwashing scraper. Multiple backwashing nozzles connected to the backwashing conveying pipe are fixed on the outside of the backwashing conveying pipe.

[0010] Several backwash discharge pipes connected to the interior are fixed on the outer side of the sedimentation tank near the bottom. Each backwash discharge pipe has a discharge control valve.

[0011] Preferably, the bottom of the dispersion water inlet overflow tank is a horizontally extending cylindrical structure, and an overflow auxiliary drive shaft is rotatably connected inside the dispersion water inlet overflow tank. Multiple overflow auxiliary drive plates are fixed on the overflow auxiliary drive shaft.

[0012] An overflow drive housing is fixed on the outside of the dispersed water inlet overflow tank. One end of the overflow auxiliary drive shaft extends into the overflow drive housing. An overflow auxiliary drive motor for driving the overflow auxiliary drive shaft to rotate is fixed inside the overflow drive housing.

[0013] Explanation: The overflow auxiliary drive motor drives the overflow auxiliary drive shaft to rotate through gear transmission. The overflow auxiliary drive shaft drives multiple overflow auxiliary drive plates to rotate together, which agitates the high turbidity water in the dispersion water overflow tank and prevents excessive accumulation of suspended matter in the high turbidity water at the bottom of the dispersion water overflow tank.

[0014] Preferably, multiple support block guide slide rods extending along the width direction of the sedimentation tank body are fixed inside the sedimentation tank body, and the sedimentation backwashing support block has a guide fitting hole, and the support block guide slide rod is slidably connected in the guide fitting hole;

[0015] The sedimentation backwashing support block has a sliding drive mating hole, in which a sliding drive screw is threadedly connected. A sliding drive housing is fixed on the outside of the sedimentation tank body. One end of the sliding drive screw extends into the sliding drive housing, and a sliding drive motor for driving the sliding drive screw to rotate is fixed inside the sliding drive housing.

[0016] Explanation: Under the action of screw transmission, the sliding drive screw drives the sedimentation backwash support block to move along the width direction of the sedimentation tank body. The sedimentation backwash support block drives the sedimentation backwash scraper to move together. The sedimentation backwash scraper pushes the suspended particles deposited at the bottom of the sedimentation tank body to the backwash discharge pipes on both sides of the width direction of the sedimentation tank body.

[0017] Preferably, the sedimentation tank body is provided with a linkage inclined plate sedimentation mechanism. The linkage inclined plate sedimentation mechanism includes multiple sedimentation blocking inclined plates arranged in parallel within the sedimentation tank body. The inner side wall of the sedimentation tank body has multiple sets of coaxially paired inclined plate shaft connection holes. The side of the sedimentation blocking inclined plate along the width direction of the sedimentation tank body is fixed with a coaxially arranged inclined plate support shaft, and the inclined plate support shaft is rotatably connected in the inclined plate shaft connection hole.

[0018] Two adjacent settlement barrier inclined plates are connected by a linkage drive rod. A linkage support seat is fixed on the side of the settlement barrier inclined plate. The linkage support seat has a linkage shaft connection hole. A linkage shaft is fixed at each end of the linkage drive rod. The linkage shaft is rotatably connected in the linkage shaft connection hole.

[0019] An inclined plate drive housing is fixed to the outside of the sedimentation tank body. An inclined plate drive shaft is coaxially fixed to one of the inclined plate support shafts. The inclined plate drive shaft extends into the inclined plate drive housing. A first driven worm gear is fixed to one end of the inclined plate drive shaft that extends into the inclined plate drive housing. An inclined plate drive motor is fixed inside the inclined plate drive housing. A first driving worm is fixed on the output shaft of the inclined plate drive motor. The first driving worm is meshed with the first driven worm gear.

[0020] Explanation: When high-turbidity water flows through the linkage inclined plate sedimentation mechanism, the sedimentation area is increased and the settling distance of suspended particles is shortened due to the setting of sedimentation barrier inclined plates, thereby improving sedimentation efficiency.

[0021] Preferably, the sedimentation tank body is provided with multiple crowding sedimentation mechanisms. Each crowding sedimentation mechanism includes two parallel crowding sedimentation support shafts rotatably connected inside the sedimentation tank body, and a crowding sedimentation guide plate is fixed on the crowding sedimentation support shaft.

[0022] A congestion settling drive housing is fixed to the outside of the sedimentation tank body. One end of the congestion settling support shaft extends into the congestion settling drive housing. A second driven worm gear is fixed to the end of the congestion settling support shaft that extends into the congestion settling drive housing. A guide plate drive motor is fixed inside the congestion settling drive housing. A second driving worm is fixed on the output shaft of the guide plate drive motor. The second driving worm is meshed with the second driven worm gear.

[0023] Explanation: The space between the two congested settling guide plates forms a "congested flow channel". As the high-turbidity water flows through the "congested flow channel", the "congested flow channel" exhibits a contraction structure that is wide at first and then narrows along the direction of the high-turbidity water flow. This forces the suspended particles in the high-turbidity water to crowd together, increasing the concentration of suspended particles in the local space and accelerating the mutual interference between suspended particles. The resulting congested sedimentation phenomenon is conducive to accelerating the settling of suspended particles.

[0024] Preferably, the congested settling guide plate is provided with a guide plate grooving mechanism, which includes multiple settling flow slots provided on the congested settling guide plate and extending through both sides thereon. The congested settling guide plate has a hollow structure inside, and a slot opening and closing control plate is slidably connected inside the congested settling guide plate. The slot opening and closing control plate has multiple settling flow adaptation slots.

[0025] The congestion settling guide plate has a fixed opening and closing control cylinder inside, and an opening and closing control sliding cylinder is slidably connected inside the opening and closing control cylinder. The outer end of the opening and closing control sliding cylinder is fixedly connected to the slotted opening and closing control plate. The opening and closing control fixed cylinder is equipped with an opening and closing control drive rod for driving the opening and closing control sliding cylinder to move.

[0026] Explanation: The opening degree of each settling flow slot is controlled by the guide plate slotting mechanism, thereby adjusting the actual working effect of the congestion settling mechanism. Multiple settling flow slots are connected to each settling flow adapter slot in a one-to-one correspondence. The settling flow slots and the settling flow adapter slots together form the "slotting mechanism channel".

[0027] Preferably, the sedimentation tank body is provided with an acoustic agglomeration mechanism, which includes an agglomeration mechanism support rod that extends horizontally and is fixed in the sedimentation tank body, and an agglomeration mechanism receiving shell is suspended and fixed on the lower side of the agglomeration mechanism support rod by a support cable.

[0028] The agglomeration mechanism housing is a hollow spherical shell, and multiple sound wave generators are fixed on the inner side wall of the agglomeration mechanism housing.

[0029] The sound wave generator is a conventional sound wave generator with a sound wave generation frequency of 20kHz to 30kHz.

[0030] Explanation: Ultrasonic waves are intermittently generated by a sound wave generator. The ultrasonic vibration energy is transmitted to the high-turbidity water through the agglomeration mechanism's containment shell. The ultrasonic vibration energy will form a specific energy field in three-dimensional space. The suspended particles vibrate together with the medium, and the suspended particles of different sizes have different relative vibration velocities. As a result, the suspended particles will collide and adhere to each other, causing them to agglomerate and facilitating faster sedimentation.

[0031] Preferably, multiple parallel sedimentation interception and flow-slowing baffles are fixed at the bottom of the sedimentation tank body.

[0032] Note: Each sedimentation and flow-damping baffle can act as a buffer and barrier, preventing the already settled suspended particles from being disturbed by the water flow.

[0033] Preferably, a sedimentation tank outlet mechanism is provided at one end of the sedimentation tank body opposite to the decentralized water inlet mechanism. The sedimentation tank outlet mechanism includes a sedimentation tank outlet flow channel fixed on the outer wall of the sedimentation tank body. The side wall of the sedimentation tank body has multiple sedimentation tank outlet slots that are connected to the interior of the sedimentation tank outlet flow channel.

[0034] The top of the sedimentation tank effluent flow channel is rotatably connected to multiple effluent filter support shafts. An effluent filter support plate is fixed on the effluent filter support shaft. The effluent filter support plate is a multi-hole hollow mechanism with two sides connected. An effluent filter screen is fixed on the side of the effluent filter support plate.

[0035] A filter tilting drive housing is fixed on the outside of the sedimentation tank effluent flow channel. One end of the effluent filter support shaft extends into the interior of the filter tilting drive housing. Two adjacent effluent filter support shafts are connected by a synchronous belt drive. A filter tilting drive motor is fixed inside the filter tilting drive housing. The output shaft of the filter tilting drive motor drives one of the effluent filter support shafts to rotate through gear transmission.

[0036] Explanation: After sedimentation treatment, the high-turbidity water becomes clear water. The clear water overflows from the sedimentation tank outlet channel into the sedimentation tank outlet flow channel, and is finally discharged from the outside of the sedimentation tank outlet flow channel. During the water discharge process, the clear water is filtered by an outlet filter screen, which helps to improve the quality of the effluent. The tilt angle of each outlet filter screen can be adjusted to facilitate the sludge removal process.

[0037] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0038] 1. The present invention has a reasonable structural design. The decentralized water inlet mechanism can deliver the high turbidity water to be treated to the sedimentation tank body more evenly and stably, avoiding uneven water distribution that could cause short-circuiting of the water flow and affect the sedimentation effect.

[0039] 2. The present invention is easy to operate. When high turbidity water flows through the linkage inclined plate sedimentation mechanism, the sedimentation area is increased and the sedimentation distance of suspended particles is shortened under the blocking effect of multiple sedimentation blocking inclined plates, thereby improving the sedimentation efficiency. Moreover, the adjacent sedimentation blocking inclined plates are synchronously driven by the linkage drive linkage, so that the sedimentation blocking inclined plates can be synchronously deflected around their respective inclined plate support rotation axis, thereby keeping the multiple sedimentation blocking inclined plates in a parallel state and improving the stability of water flow.

[0040] 3. In the congestion settling mechanism of the present invention, the space between the two congestion settling guide plates forms a "congestion flow channel". During the process of high turbidity water flowing through the "congestion flow channel", the "congestion flow channel" presents a contraction structure that is wide at first and then narrows along the flow direction of high turbidity water, which forces the suspended particles in the high turbidity water to crowd together, thereby increasing the concentration of suspended particles in the local space, accelerating the mutual interference between suspended particles, and forming a congestion sedimentation phenomenon, which is conducive to accelerating the settling of suspended particles.

[0041] 4. In this invention, the opening degree of each settling flow slot is controlled by the guide plate slotting mechanism, thereby adjusting the actual working effect of the congestion settling mechanism. Multiple settling flow slots are connected to each settling flow adaptation slot in a one-to-one correspondence. The settling flow slots and the settling flow adaptation slots together form a "slotting mechanism channel".

[0042] 5. In this invention, an ultrasonic wave generator is used to intermittently generate ultrasonic waves. The ultrasonic vibration energy is transmitted to the high turbidity water through the agglomeration mechanism's containment shell. The ultrasonic vibration energy will form a specific energy field in three-dimensional space. The ultrasonic vibration energy causes the suspended particles to vibrate together with the medium. The suspended particles of different sizes have different relative vibration velocities. As a result, the suspended particles will collide and adhere to each other, causing the suspended particles to agglomerate and making it easier for the suspended particles to settle down faster.

[0043] 6. In this invention, the use of an outlet filter screen to assist in the filtration of clean water is beneficial to improving the quality of the effluent; and the tilt angle of each outlet filter screen can be adjusted to facilitate the sludge removal process. Attached Figure Description

The extension direction of the dispersion inlet overflow tank 12 is parallel to the width direction of the sedimentation tank body 100, so that the high turbidity water is evenly dispersed in the dispersion inlet overflow tank 12. The high turbidity water in the dispersion inlet overflow tank 12 then enters the interior of the dispersion inlet buffer tank 11 through the dispersion inlet overflow slot 120. Finally, the high turbidity water in the dispersion inlet buffer tank 11 enters the interior of the sedimentation tank body 100 through multiple dispersion inlet slots 110.

[0102] During this process, the overflow auxiliary drive motor 133 drives the overflow auxiliary drive shaft 13 to rotate through gear transmission. The overflow auxiliary drive shaft 13 drives multiple overflow auxiliary drive plates 131 to rotate together, which stirs up the high turbidity water in the dispersion inlet overflow tank 12 and prevents the suspended matter in the high turbidity water from accumulating too much at the bottom of the dispersion inlet overflow tank 12.

[0103] The two congestion settling support shafts 41 in each congestion settling mechanism 40 extend along the width direction of the sedimentation tank body 100, and the two congestion settling support shafts 41 are arranged in the vertical direction.

[0104] The rotation of the congestion settlement support shaft 41 can control the deflection of the congestion settlement guide plate 42, thereby adjusting the included angle between the two congestion settlement guide plates 42.

[0105] The space between the two congestion settling guide plates 42 forms a "congestion flow channel". When high turbidity water flows through the congestion settling mechanism 40, that is, when it flows through the "congestion flow channel", along the flow direction of high turbidity water, the "congestion flow channel" presents a contraction structure that is wide at first and then narrows, which forces the suspended particles in the high turbidity water to crowd together, increasing the concentration of suspended particles in the local space, accelerating the mutual interference between suspended particles, and forming a congestion sedimentation phenomenon, which is conducive to accelerating the sedimentation of suspended particles.

[0106] The guide plate drive motor 432 is a servo motor of the prior art. The output shaft of the guide plate drive motor 432 drives the congestion settling support shaft 41 to rotate through the meshing connection between the second active worm gear 433 and the second driven worm wheel 431, thereby causing the congestion settling support shaft 41 to drive the congestion settling guide plate 42 to deflect.

[0107] The opening degree of each settling flow slot 441 is controlled by the guide plate slotting mechanism 44, thereby adjusting the actual working effect of the congestion settling mechanism 40.

[0108] Multiple settling flow slots 441 are connected one-to-one with each settling flow adapter slot 443, and the settling flow slots 441 and settling flow adapter slots 443 together form a "slotting mechanism channel".

[0109] The opening and closing control drive rod 446 is an existing electric telescopic rod. The extension or retraction of the inner rod of the opening and closing control drive rod 446 can drive the slotting opening and closing control plate 442 to slide inside the congested settling guide plate 42, thereby controlling the overlapping area between the settling flow slot 441 and the settling flow adaptation slot 443, and thus controlling the opening degree of the "slotting mechanism channel".

[0110] The axis of the opening and closing control fixed cylinder 444 is arranged along the width direction of the sedimentation tank body 100. The sliding direction of the slotted opening and closing control plate 442 is also along the width direction of the sedimentation tank body 100. The inner rod of the opening and closing control drive rod 446 extends or retracts, driving the opening and closing control sliding cylinder 445 together with the slotted opening and closing control plate 442 to move along the axis of the opening and closing control fixed cylinder 444.

[0111] When the opening of the "grooving mechanism channel" is small, the suspended particles in the high turbidity water will be more "crowded" as the high turbidity water flows through the "crowded flow channel". When the opening of the "grooving mechanism channel" is large, some of the high turbidity water will overflow through the "grooving mechanism channel" as the high turbidity water flows through the "crowded flow channel". At this time, the suspended particles in the high turbidity water will be less "crowded".

[0112] When high-turbidity water flows through the acoustic agglomeration mechanism 50, the acoustic generator 53 intermittently generates 22kHz ultrasonic waves. The ultrasonic vibration energy is transmitted to the high-turbidity water through the agglomeration mechanism housing shell 52. The ultrasonic vibration energy will form a specific energy field in three-dimensional space. The ultrasonic vibration energy causes the suspended particles to vibrate together with the medium. The suspended particles of different sizes have different relative vibration velocities. As a result, the suspended particles will collide and adhere to each other, causing them to agglomerate and increase in both volume and weight. As the agglomerated suspended particles gradually become larger, they can no longer vibrate with the ultrasonic vibration and can only move randomly. In this process, they continue to collide and adhere, eventually causing the agglomerated suspended particles to become even larger and settle down.

[0113] When high-turbidity water flows through the linkage inclined plate sedimentation mechanism 30, the sedimentation area is increased and the sedimentation distance of suspended particles is shortened due to the setting of sedimentation barrier inclined plate 31, thereby improving sedimentation efficiency.

[0114] Furthermore, the tilt angle of multiple settlement-blocking inclined plates 31 can be adjusted in a coordinated manner.

[0115] The inclined plate drive motor 333 is a servo motor of the prior art. The output shaft of the inclined plate drive motor 333 drives the inclined plate drive shaft 331 to rotate through the meshing of the first active worm 334 and the first driven worm wheel 332. The inclined plate drive shaft 331 drives the inclined plate support shaft 311 to deflect together with the settlement barrier inclined plate 31. The adjacent two settlement barrier inclined plates 31 are synchronously driven through the linkage drive link 32, so that the settlement barrier inclined plates 31 can deflect synchronously around their respective inclined plate support shafts 311, thereby keeping the multiple settlement barrier inclined plates 31 in a parallel state at all times.

[0116] During the above series of processes, suspended particles in high turbidity water will settle and accumulate at the bottom of the sedimentation tank body 100. Each sedimentation interception and flow-slowing baffle 15 can play a buffering and blocking effect, preventing the already settled suspended particles from being disturbed by the water flow.

[0117] After high turbidity water is treated by sedimentation to form clear water, the clear water will overflow through the sedimentation tank outlet channel 160 into the sedimentation tank outlet flow channel 161, and finally be discharged from the outer end of the sedimentation tank outlet flow channel 161.

[0118] During the water output process, the water output filter screen 164 is used to assist in the filtration of the clean water, which helps to improve the quality of the output water.

[0119] Furthermore, the tilt angle of each outlet filter screen 164 can be adjusted. The output shaft of the filter tilt drive motor 166 drives one of the outlet filter support shafts 162 to rotate through gear transmission. This outlet filter support shaft 162 then drives the other outlet filter support shafts 162 to rotate synchronously through synchronous belt transmission. The outlet filter support shaft 162 drives the outlet filter support plate 163 and the outlet filter screen 164 to deflect together, thereby adjusting the tilt angle of the outlet filter screen 164, which facilitates the slag discharge work and adjusts the actual filtration effect of the outlet filter screen 164.

[0120] The sedimentation backwashing mechanism 20 is used to centrally clean the suspended particles deposited at the bottom of the sedimentation tank body 100. The sliding drive motor 252 is a servo motor of the prior art. The output shaft of the sliding drive motor 252 drives the sliding drive screw 25 to rotate through gear transmission. Under the action of the screw transmission, the sliding drive screw 25 drives the sedimentation backwashing support block 21 to move along the width direction of the sedimentation tank body 100. The sedimentation backwashing support block 21 drives the sedimentation backwashing scraper 211 to move together. The sedimentation backwashing scraper 211 pushes the suspended particles deposited at the bottom of the sedimentation tank body 100 to the backwashing external discharge pipes 23 on both sides of the width direction of the sedimentation tank body 100.

[0121] After all the suspended particles have accumulated at the backwash discharge pipe 23, the discharge control valve 230 is opened. Under the impact of the water flow, the suspended particles accumulated at the backwash discharge pipe 23 will be discharged along with the water flow through the backwash discharge pipe 23, thus avoiding excessive accumulation of suspended particles at the bottom of the sedimentation tank body 100, which would affect the sedimentation efficiency of the sedimentation tank itself.

[0122] After all the water in the sedimentation tank body 100 is drained, clean water is delivered to the backwash delivery pipe 22 through the pipeline using the existing technology delivery pump. The clean water is sprayed out from each backwash nozzle 220 to flush and clean the bottom of the sedimentation tank body 100. The backwash delivery pipe 22 can move together with the sedimentation backwash scraper 211 to thoroughly clean the bottom of the sedimentation tank body 100.
