Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment device. Background Technology

[0002] Industrial production and daily life generate large amounts of wastewater containing suspended impurities, colloidal particles, and other pollutants. If this wastewater is discharged directly without treatment, it will cause serious pollution to the ecological environment. Therefore, wastewater treatment has become a crucial aspect of environmental protection. Flocculation and sedimentation is a widely used process in wastewater treatment. It involves adding flocculants to wastewater, causing pollutants to agglomerate into flocs. Solid-liquid separation is then achieved through filtration and sedimentation, thus purifying the wastewater.

[0003] In the prior art, patent publication number CN117735787A, entitled "High-Concentration Organic Waste Flocculation and Sedimentation Treatment System," discloses a flocculation treatment structure: A feed pipe is fixedly connected to one side of the system tank; an installation platform is provided on the top of the tank, on which a chemical tank and a chemical pump are fixed; the pump's suction end is connected to the chemical tank, and its outlet end is connected to a premixing pipe. The premixing pipe passes through the feed pipe and has multiple inlet holes along its circumference; two first partitions and one second partition are fixed between the inner walls of the tank; a connecting pipe is connected to one side of the first partition, and a premixing component is configured at the feed pipe to complete the premixing operation. This technology utilizes the premixing pipe to pre-discharge the flocculant into the feed pipe, which can improve the mixing efficiency of the flocculant and wastewater to a certain extent.

[0004] Currently, flocculation and sedimentation wastewater treatment devices widely adopt basic structures such as premixing and chemical dosing. However, in practical applications, most conventional devices still use a single, straight-through flow channel, resulting in a short residence time of wastewater and flocculant within the channel and insufficient mixing uniformity. Simultaneously, the devices lack targeted mixing enhancement and agitation structures, leading to insufficient contact between pollutants and flocculants, resulting in small, loose, and incomplete floc formation, thus reducing subsequent solid-liquid separation efficiency. Furthermore, some enhanced mixing devices require external power sources such as motors and agitators, resulting in high energy consumption, complex structures, and high installation and maintenance costs, which to some extent limits the large-scale promotion and use of these devices. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a wastewater treatment device that solves the technical problems of uneven mixing, insufficient floc formation, and high energy consumption in traditional wastewater treatment devices.

The first tank has an inlet at one end and the second tank has an outlet at one end. The end of the second tank away from the outlet is connected to the end of the first tank away from the inlet, forming a vortex flow channel for wastewater to flow inside the treatment tank. A dosing area is provided at the connection between the first tank and the second tank for adding flocculant to the flowing wastewater. The manifold is located at the connection between the first box and the second box, and the manifold is filled with several packing components to promote the full mixing of wastewater and flocculant. The vibrating element is located at the bottom of the manifold, and the vibrating element includes a power unit and a vibration unit. The power unit generates driving force when impacted by water flow, which can drive the vibration unit to reciprocate on the bottom of the manifold, thereby causing the manifold and the internal packing components to vibrate synchronously.

[0007] Optionally, a filter basket is provided at the liquid inlet to intercept and collect solid impurities in the wastewater.

[0008] Optionally, filter plate assemblies can be detachably installed in both the first and second housings, with the top surface of the filter plate assembly being lower than the top surface of the corresponding housing.

[0009] Optionally, a perforated plate is provided at the connection between the first housing and the second housing. The perforated plate is located below the manifold and is used to filter impurities and support the vibrating component.

[0010] Optionally, the manifold includes a cylinder and a placement plate; the cylinder is located at the connection between the first box and the second box; the placement plate is slidably disposed at the bottom of the cylinder along the axis of the cylinder, and a plurality of packing components are stacked on the placement plate; the vibrating part abuts against the bottom surface of the placement plate and is used to drive the placement plate to reciprocate along the axis of the cylinder; the placement plate has a plurality of filter grooves for wastewater and flocculant to pass through.

[0011] Optionally, the packing element includes a ring, a bent plate, and a baffle; the ring has several through grooves spaced apart on its circumferential sidewalls; one end of the bent plate is fixed in the through groove, and the other end extends into the ring, and the bent plate is inclined relative to the axis of the ring for dispersing wastewater and flocculant; the baffle is fixed to the bent plate, and a through hole is formed between the baffle and the bend of the bent plate for changing the flow path of wastewater and flocculant.

[0012] Optionally, the vibrating part of the vibrating element includes a fixed plate, a push rod, a connecting member, and an elastic member; the fixed plate is fixed to the perforated plate; the push rod passes through the fixed plate and is slidably connected to it, and a top post is provided at the top of the push rod, the top post abutting against the bottom surface of the placement plate; the connecting member is sleeved on the push rod, and the connecting member is hinged to the two side walls of the second housing; the elastic member is disposed between the connecting member and the fixed plate.

[0013] Optionally, the power unit of the vibrating element includes a cam and a drive wheel; the cam is rotatably disposed at the bottom of the fixed plate and abuts against the bottom end of the push rod; the drive wheel is coaxially fixedly connected to the cam and is used to rotate under the impact of water flow and drive the cam to rotate synchronously.

[0014] Optionally, the connecting member includes a connecting sleeve, a piston rod, a fixed cylinder, and a first spring; the connecting sleeve is sleeved on the push rod; one end of the piston rod is hinged to the connecting sleeve, and the other end is slidably disposed in the fixed cylinder; the first spring is sleeved on the piston rod and located in the fixed cylinder, and is used to pull the piston rod into the fixed cylinder.

[0015] Optionally, the drive wheel is an impeller; the outer walls of the first and second boxes are provided with a drainage pipe, the inlet end of the drainage pipe is connected to the first box, and the outlet end is connected to the second box and faces the drive wheel, for guiding the water flow to impact the drive wheel; the second box is provided with a number of horizontally arranged and vertically spaced baffles for reducing the wastewater flow rate and extending the residence time.

[0016] The beneficial effects of this invention are as follows: In this invention, wastewater enters the treatment tank through the inlet of the first tank and flows along the channel of the first tank to the connection point with the second tank. In the dosing area, flocculant is added to the wastewater flowing through this point. The mixture of wastewater and flocculant enters the manifold and flows through multiple packing components inside the manifold. Simultaneously, the water flow impacts the power unit of the vibrating component, causing the power unit to generate driving force and drive the vibrating component to repeatedly strike the bottom of the manifold. The manifold vibrates accordingly, causing the internal packing components to vibrate synchronously. The packing components stir the mixture, promoting thorough mixing of the wastewater and flocculant. The mixed wastewater enters the second tank through the connection point, flows along the rotating channel in the second tank, and finally exits from the outlet of the second tank, completing the preliminary treatment.

[0017] By connecting the upper and lower chambers to form a rotary flow channel, the contact time between wastewater and flocculant is extended, avoiding the problem of short contact time in traditional single-channel systems. The packing components in the manifold, in conjunction with the vibration of the vibrating components, further improve the mixing uniformity of wastewater and flocculant, promote the full formation of flocs, and lay a good foundation for subsequent solid-liquid separation. The vibrating components are powered by the impact of water flow, eliminating the need for an additional power source, thus reducing the energy consumption of the device. The overall structure is simple, with few parts, making it easy to process, manufacture, and promote its application. It effectively solves the pain points of traditional devices, such as uneven mixing, insufficient floc formation, high energy consumption, and complex structure. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0023] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5As shown, a wastewater treatment device according to an embodiment of the present invention is illustrated. The treatment tank 1 is divided into upper and lower tanks along the vertical direction. The two tanks are fixed to each other. One end of the first tank 101 is provided with an opening for wastewater to enter, and one end of the second tank 102 is provided with an opening for discharging treated wastewater. The end of the second tank 102 away from the outlet is connected to the end of the first tank 101 away from the inlet, so that a rotating channel for wastewater circulation is formed inside the treatment tank 1. A special area for adding flocculant is provided at the connection between the two tanks. A manifold 2 is installed at this connection. Multiple packing components 3 are placed inside the manifold 2. A vibrating component 4 is installed at the bottom of the manifold 2. The vibrating component 4 consists of a power unit 41 and a vibration unit 42. The power unit 41 can obtain driving force through water flow impact, thereby driving the vibration unit 42 to reciprocate to strike the bottom of the manifold 2, so that the packing components 3 inside the manifold 2 vibrate synchronously.

[0028] In the above scheme, wastewater enters the treatment tank 1 from the inlet of the first tank 101 and flows along the channel of the first tank 101 to the connection with the second tank 102. The dosing zone 106 adds flocculant to the wastewater flowing through this point. The mixture of wastewater and flocculant enters the manifold 2 and flows through multiple packing components 3 inside the manifold 2. At the same time, the water flow impacts the power unit 41 of the vibrating component 4, causing the power unit 41 to generate driving force and drive the vibrating component 42 to repeatedly strike the bottom of the manifold 2. The manifold 2 vibrates accordingly and drives the internal packing components 3 to vibrate synchronously. The packing components 3 stir the mixture, promoting the full mixing of wastewater and flocculant. The mixed wastewater enters the second tank 102 through the connection and flows along the rotating channel in the second tank 102. Finally, it is discharged from the outlet of the second tank 102, completing the preliminary treatment.

[0029] The first box 101 and the second box are connected to form a rotary flow channel 105, which prolongs the contact time between wastewater and flocculant and avoids the problem of short contact time in traditional single flow channels. The packing component 3 in the manifold 2, together with the vibration of the vibrating component 4, further improves the mixing uniformity of wastewater and flocculant, promotes the full formation of flocs, and lays a good foundation for subsequent solid-liquid separation. The vibrating component 4 is powered by water flow impact, without the need for an additional power source, which reduces the energy consumption of the device. The overall structure is simple, with few parts, which makes it easy to process, manufacture and promote its application. It effectively solves the pain points of traditional devices such as uneven mixing, insufficient floc formation, high energy consumption and complex structure.

[0030] Furthermore, the inlet is connected to an external wastewater discharge pipe, allowing wastewater to directly enter the treatment tank 1 from the discharge pipe. A filter basket 5 is installed at the inlet, which is adapted to be installed inside the inlet. The filter basket 5 can perform preliminary filtration on the wastewater entering the treatment tank 1, and is specifically used to collect solid impurities contained in the wastewater, so as to prevent solid impurities from entering the treatment tank 1 and affecting the subsequent treatment process.

[0031] In the above scheme, wastewater flows out from the wastewater discharge pipe and first enters the filter basket 5 at the inlet. The filter basket 5 intercepts and collects solid impurities in the wastewater. After filtration by the filter basket 5, most of the solid impurities are removed, and the wastewater then enters the first tank 101 for subsequent flocculation and mixing treatment. When the amount of solid impurities collected in the filter basket 5 reaches a certain level, the filter basket 5 can be removed for cleaning. After cleaning, it is reinstalled at the inlet to ensure the filtration effect. This method can remove solid impurities from the wastewater at the initial stage of entering the treatment tank 1, preventing solid impurities from clogging the manifold 2, packing components 3, or subsequent channels, ensuring the normal operation of the device, reducing the frequency of maintenance, and lowering maintenance costs. At the same time, it avoids the mixing of solid impurities with flocculants, which affects the floc formation effect, further improving the wastewater treatment efficiency. The filter basket 5 is simple and easy to set up, requiring no complex structure, and is easy to clean and maintain, improving the practicality of the device.

[0032] Furthermore, both the first housing 101 and the second housing 102 are equipped with filter plate assemblies 6. The filter plate assemblies 6 are detachable, which facilitates installation, disassembly and replacement. The top height of the filter plate assembly 6 is lower than the top height of the corresponding housing, so it will not affect the normal flow of wastewater inside the housing. The filter plate assembly 6 can further filter the flowing wastewater and intercept flocs and residual impurities in the wastewater.

[0033] In the above scheme, when the wastewater flows in the first tank 101, it passes through the filter plate assembly 6. The filter plate assembly 6 intercepts the flocs initially formed in the wastewater and the impurities that have not been completely removed. The filtered wastewater continues to flow to the connecting point and mixes with the flocculant. After the mixed wastewater enters the second tank 102, it passes through the filter plate assembly 6 in the second tank 102 again to further intercept flocs and impurities, ensuring that the discharged wastewater is cleaner. When too many flocs and impurities are attached to the surface of the filter plate assembly 6 and affect the filtration effect, the filter plate assembly 6 can be disassembled for cleaning or replacement and then reinstalled back into the tank.

[0034] The detachable filter plate assembly 6 facilitates maintenance and replacement, reducing maintenance difficulty and cost. Filter plate assemblies 6 are installed in both the upper and lower chambers, achieving multi-stage filtration, effectively improving solid-liquid separation, and making the treated wastewater cleaner. The top of the filter plate assembly 6 is lower than the top surface of the chamber, so it will not obstruct the flow of wastewater, ensuring the smoothness of wastewater treatment. At the same time, it reduces the accumulation of flocs in the chamber, avoids channel blockage, and further improves the treatment efficiency and stability of the device.

[0035] Furthermore, a perforated plate 7 is installed at the connection between the first housing 101 and the second housing 102. The perforated plate 7 is located directly below the manifold 2. The surface of the perforated plate 7 has uniformly distributed perforations, which can allow the wastewater and flocculant mixture to pass through while intercepting larger impurities in the wastewater. At the same time, the perforated plate 7 has a certain load-bearing capacity to support the vibrating element 4, so that the vibrating element 4 can be stably installed at the bottom of the manifold 2 and ensure the normal operation of the vibrating element 4.

[0036] In the above scheme, after the mixture of wastewater and flocculant flows out of the manifold 2, it first passes through the perforated plate 7 below. The perforated plate 7 intercepts larger impurities and incompletely formed flocs in the mixture that are not dispersed by the packing element 3. The filtered mixture enters the second chamber 102 through the perforated plate 7. At the same time, the perforated plate 7 provides stable support for the vibrating element 4. The vibration generated by the vibrating element 4 during operation will not cause its position to shift, ensuring that the vibrating element 4 can continuously and stably drive the manifold 2 and the packing element 3 to vibrate, thus ensuring the mixing effect.

[0037] The perforated plate 7 achieves secondary filtration of the mixed liquid, further removing impurities and improving the wastewater treatment effect. At the same time, it provides stable support for the vibrating element 4, ensuring the working stability of the vibrating element 4, preventing the vibrating element 4 from shifting or being damaged due to vibration, and extending the service life of the vibrating element 4. The perforated plate 7 has a simple structure and is easy to install. It does not require additional support structures, which simplifies the overall structure of the device, reduces manufacturing costs, and facilitates subsequent cleaning and maintenance.

[0038] Furthermore, the manifold 2 consists of a cylinder 21 and a placement plate 22. The cylinder 21 is installed at the connection between the upper and lower boxes. The placement plate 22 is slidably installed inside the cylinder 21 along the axial direction of the cylinder 21 and is located at the bottom of the cylinder 21. Multiple packing components 3 are neatly stacked on the placement plate 22. The vibrating part 42 of the vibrating component 4 is in close contact with the bottom surface of the placement plate 22. When the vibrating part 42 is activated, it can drive the placement plate 22 to move back and forth along the axial direction of the cylinder 21. Multiple through filter grooves are opened on the surface of the placement plate 22. The size of the filter grooves is adapted to the flow of wastewater and flocculant and does not affect the normal flow of the mixed liquid.

[0039] In the above scheme, after the mixture of wastewater and flocculant enters the cylinder 21 of the manifold 2, it flows through the packing member 3 on the placement plate 22. The vibrating part 42 of the vibrating member 4 is activated, causing the placement plate 22 to move up and down along the axis of the cylinder 21. The movement of the placement plate 22 causes the packing member 3 above to move up and down synchronously. During the movement, the packing member 3 fully contacts and collides with the mixture, and fully stirs the mixture, promoting the uniform mixing of wastewater and flocculant. The mixed wastewater and flocculant flow out of the manifold 2 through the filter groove on the placement plate 22 and enter the mesh plate 7 below for further filtration. The sliding arrangement of the placement plate 22 enables the packing element 3 to move up and down reciprocally. Compared with the fixed packing element 3, this significantly increases the contact area and collision frequency with the mixed liquid, further enhancing the mixing effect and promoting the full formation of flocs. The filter groove on the placement plate 22 ensures smooth flow of the mixed liquid and avoids clogging. At the same time, the packing element 3 is stacked on the placement plate 22, which facilitates subsequent removal, cleaning and replacement, reducing maintenance difficulty. The overall structural design is reasonable, further optimizing the mixing function of the manifold 2 and improving the processing efficiency of the device.

[0040] Furthermore, the packing component 3 consists of a ring 31, a bent plate 32, and a baffle 33. The ring 31 has a hollow structure, and multiple through grooves 311 are evenly spaced on the circumferential sidewall. One end of the bent plate 32 is fixedly installed inside the through groove 311, and the other end extends into the internal space of the ring 31. The bent plate 32 is inclined to the axial direction of the ring 31. The baffle 33 is fixedly installed on the bent plate 32. A through hole is formed between the baffle 33 and the bend of the bent plate 32. The size of the through hole is adapted to the flow of wastewater and flocculant, and can change the flow direction of the mixed liquid.

[0041] In the above scheme, after the mixture of wastewater and flocculant enters the manifold 2, it flows through multiple packing components 3. Part of the mixture enters the interior of the ring 31 through the through groove 311 on the side wall of the ring 31, and part of it flows directly through the exterior of the ring 31. The mixture entering the interior of the ring 31 comes into contact with the inclined bending plate 32. The bending plate 32 disperses the mixture, making it evenly dispersed. At the same time, the through holes formed by the baffle 33 and the bending plate 32 change the flow path of the mixture, causing the mixture to flow turbulently inside the ring 31, further promoting the mixing of wastewater and flocculant. The multiple packing components 3 work together to make the mixture fully stirred and mixed in the manifold 2. The combined design of the ring 31, the bending plate 32, and the baffle 33 can effectively disperse the mixed liquid and change its flow path, increase the contact area and contact time between wastewater and flocculant, improve the mixing uniformity, and promote the full formation of flocs. Compared with traditional single packing, the structure of this packing component 3 is more reasonable and the mixing effect is better. At the same time, the setting of the through groove 311 and through hole ensures the smooth flow of the mixed liquid and avoids clogging. The structure of the packing component 3 is simple, easy to process and manufacture, has low cost, and has a long service life, and can play a stable mixing role for a long time.

[0042] Furthermore, the vibrating part 42 of the vibrating element 4 is composed of a fixed plate 411, a push rod 412, a connecting member 414, and an elastic member 415. The fixed plate 411 is fixedly installed on the mesh plate 7. The push rod 412 passes through the fixed plate 411 and forms a sliding connection with the fixed plate 411. A top post 413 is provided at the top of the push rod 412. The top post 413 abuts tightly against the bottom surface of the placement plate 22. The connecting member 414 is sleeved on the push rod 412, and both ends of the connecting member 414 are connected to the second housing 102. The two side walls are hinged, and the elastic element 415 is installed between the connector 414 and the fixed plate 411 to provide elastic support for the connector 414. The power part 41 of the vibrating element 4 consists of a cam 421 and a drive wheel 422. The cam 421 is rotatably installed at the bottom of the fixed plate 411 and abuts against the bottom end of the push rod 412. The drive wheel 422 is also rotatably installed at the bottom of the fixed plate 411 and is coaxially fixedly connected to the cam 421. It can rotate under the impact of water flow and drive the cam 421 to rotate synchronously.

[0043] In the above scheme, the water flow impacts the drive wheel 422, causing the drive wheel 422 to rotate. The drive wheel 422 drives the coaxial cam 421 to rotate synchronously. During the rotation of the cam 421, it continuously pushes the bottom end of the push rod 412, causing the push rod 412 to slide up and down along the fixed plate 411. The top post 413 at the top of the push rod 412 drives the placement plate 22 to move up and down reciprocally. At the same time, the connecting piece 414 rotates around the hinge point with the side wall of the box under the drive of the push rod 412. The elastic piece 415 extends and retracts during the rotation of the connecting piece 414, playing a buffering and reset role, so that the push rod 412 can move back and forth smoothly, thereby driving the placement plate 22 and the packing piece 3 to vibrate stably, promoting the full mixing of wastewater and flocculant. When the water flow stops impacting, the elastic piece 415 drives the connecting piece 414 and the push rod 412 to reset, waiting for the next water flow impact. Power is provided by the water flow impact driving wheel 422, eliminating the need for additional power sources such as motors, greatly reducing the energy consumption of the device and meeting energy-saving requirements. The cooperative design of cam 421 and push rod 412 can convert the rotational motion of drive wheel 422 into the reciprocating linear motion of push rod 412, resulting in high transmission efficiency and structural stability. The elastic element 415 plays a role in buffering and resetting, avoiding violent collisions between parts during vibration, extending the service life of parts, ensuring the smoothness of vibration, and improving the mixing effect. The overall structure is compact, occupies little space, and is easy to install and maintain.

[0044] Furthermore, the connector 414 is composed of a connecting sleeve 4141, a piston rod 4142, a fixed cylinder 4143, and a first spring 4144. The connecting sleeve 4141 is fitted onto the push rod 412 and moves synchronously with the push rod 412. One end of the piston rod 4142 is hinged to the connecting sleeve 4141, and the other end is slidably inserted into the connecting sleeve 4141. The fixed cylinder 4143 is fitted onto the outside of the piston rod 4142 and forms a sliding fit with the piston rod 4142. The first spring 4144 is fitted onto the piston rod 4142 and is located inside the fixed cylinder 4143. The two ends of the first spring 4144 are respectively connected to the fixed cylinder 4143 and the piston rod 4142, and can generate a pulling force to pull the piston rod 4142 into the fixed cylinder 4143.

[0045] In the above scheme, when the push rod 412 slides up and down, it drives the connecting sleeve 4141 to move up and down synchronously. The connecting sleeve 4141 drives the piston rod 4142 to move. The piston rod 4142 slides back and forth inside the fixed cylinder 4143. At the same time, the first spring 4144 is stretched or compressed. When the push rod 412 moves upward, the piston rod 4142 is pulled out of the fixed cylinder 4143, and the first spring 4144 is stretched, generating a pulling force into the fixed cylinder 4143. When the push rod 412 moves downward, the pulling force of the first spring 4144 drives the piston rod 4142 to retract into the fixed cylinder 4143, assisting the push rod 412 to reset. At the same time, it buffers the impact force generated during the movement of the push rod 412, making the movement of the connecting piece 414 more stable, thereby ensuring that the push rod 412 drives the placement plate 22 to vibrate smoothly.

[0046] The first spring 4144 further enhances the buffering and reset capabilities of the connector 414, preventing severe impacts during the movement of the push rod 412, protecting components, and extending the service life of the device. The sliding fit between the piston rod 4142 and the fixed cylinder 4143 makes the movement of the connector 414 more flexible, adapting to the reciprocating motion of the push rod 412, ensuring the movement stability of the vibrating part 42, thereby improving the vibration effect of the packing 3 and promoting thorough mixing of wastewater and flocculant. At the same time, the connector 414 has a simple structure, is easy to manufacture, has low cost, and is easy to install and maintain.

[0047] Furthermore, the drive wheel 422 adopts an impeller structure. The blades of the impeller can better accept the impact of water flow and generate greater driving force. Drainage pipes 8 are installed on the outer walls of the first box 101 and the second box 102. One end of the drainage pipe 8 is connected to the inside of the first box 101, and the other end is connected to the inside of the second box 102. The liquid outlet end of the drainage pipe 8 is set towards the impeller, which can divert the wastewater of the first box 101 to the impeller, impact the impeller, and drive the impeller to rotate.

[0048] In the above scheme, after the wastewater enters the first tank 101, part of the wastewater flows along the tank channel, and the other part of the wastewater enters the inlet end of the diversion pipe 8. The diversion pipe 8 guides this part of the wastewater to the impeller of the second tank 102. The wastewater sprayed from the outlet end of the diversion pipe 8 impacts the blades of the impeller, causing the impeller to rotate. The impeller drives the coaxial cam 421 to rotate synchronously, thereby driving the vibration part 42 to move, causing the placement plate 22 and the packing 3 to vibrate, promoting the mixing of wastewater and flocculant. After impacting the impeller, the wastewater sprayed from the diversion pipe 8 merges with the wastewater in the second tank 102, and after being filtered together, it is discharged from the outlet. The impeller structure of the drive wheel 422 can receive water flow impact more efficiently, improve driving force, and ensure the vibration effect of the vibrating element 4. The setting of the diversion pipe 8 can actively guide some wastewater to impact the impeller, ensuring that even when the water flow speed is slow, it can provide sufficient driving force for the drive wheel 422, ensuring that the vibrating element 4 can work continuously and stably without the need for an additional power source, further reducing energy consumption. The diversion pipe 8 is installed on the outer wall of the box, which does not occupy the internal space of the box and does not affect the normal flow of wastewater. At the same time, it is easy to install and maintain, improving the stability and applicability of the device.

[0049] Furthermore, multiple baffles 9 are installed inside the second housing 102. The baffles 9 are arranged horizontally and are evenly spaced along the vertical direction. The two ends of the baffles 9 are fixedly connected to the side wall of the second housing 102, which can block the flow of wastewater, change the flow path of wastewater, and slow down the flow speed of wastewater inside the second housing 102.

[0050] In the above scheme, the wastewater mixed by the manifold 2 enters the second tank 102 and flows along the channel of the second tank 102. When the wastewater encounters the horizontally arranged baffles 9, the flow direction is changed, and it needs to bypass the baffles 9 to continue flowing. The multiple baffles 9 arranged at intervals make the wastewater form a zigzag flow inside the second tank 102, which greatly prolongs the residence time of the wastewater in the second tank 102, while slowing down the flow velocity of the wastewater, allowing sufficient time for the flocs in the wastewater to settle, thus achieving better solid-liquid separation. The setting of the baffles 9 slows down the flow velocity of the wastewater, prolongs the residence time of the wastewater in the second tank 102, provides sufficient time for the flocs to settle, improves the solid-liquid separation effect, and makes the treated wastewater cleaner. At the same time, the baffles 9 change the flow path of the wastewater, avoid short-circuit flow of the wastewater, and ensure that all wastewater is fully treated. The baffles 9 have a simple structure, are easy to install, have low cost, and require no additional power, further optimizing the treatment effect of the device and improving the practicality and reliability of the device.
