Description

Technical Field

[0001] This invention relates to the field of wastewater purification technology, and particularly to flocculation structures and flocculation equipment. Background Technology

[0002] In wastewater treatment, flocculation is necessary. Flocculation primarily uses physical and chemical methods to coagulate suspended solids, colloids, and other impurities in wastewater or tap water into larger particles, facilitating sedimentation or filtration. During flocculation, sufficient reaction time between the chemicals and wastewater must be ensured, and the reaction must be uniform without dead zones to guarantee effective flocculation. Current flocculation reaction technologies include mesh-type flocculation reactors and perforated cyclone flocculation reactors.

[0003] However, the existing flocculation reactor structure lacks an effective structure to block and cut off the water flow, which causes the sewage to flow through the flocculation reactor structure at a relatively fast speed. This results in the sewage and the reagent flowing together, which easily produces laminar flow. As a result, the overall mixing effect of sewage and reagent is poor, which in turn leads to poor flocculation effect. Summary of the Invention

[0004] The main objective of this invention is to provide a flocculation structure and flocculation device, which aims to divide the water flow and increase the rotating eddy current of the wastewater, thereby enabling the wastewater and the reagent to mix and react fully, thus improving the flocculation effect.

[0005] To achieve the above objectives, the present invention proposes a flocculation structure, the flocculation structure comprising:

[0006] The main body includes multiple mounting plates, which enclose a flocculation chamber; and

[0007] Multiple flow guiding structures are provided, each of which is disposed on an installation plate. The multiple flow guiding structures are located in the flocculation chamber. Each flow guiding structure includes a main flow plate and a secondary flow plate. The main flow plate forms multiple flow guiding channels, and the secondary flow plates are evenly distributed in the multiple flow guiding channels.

[0008] In one embodiment, the plane containing the surface of the main flow guide plate of the same flow guide structure is set at an angle to the plane containing the surface of the auxiliary flow guide plate;

[0009] And / or, the planes on which the main flow plates of different flow guiding structures are located are arranged at an angle to each other;

[0010] And / or, the planes on which the guide plates of different guide structures are located are arranged at an angle to each other.

[0011] In one embodiment, the flocculation structure further includes an inlet end and an outlet end, one end of the main flow plate is disposed at the inlet end, and the other end of the main flow plate is disposed at the outlet end. The extension direction of the main flow plate is set at an angle to the direction of the line connecting the inlet end and the outlet end, so that the flow channel extends in a spiral shape from the inlet end to the outlet end.

[0012] In one embodiment, the main flow plate includes a main connecting edge and a main flow edge, the main connecting edge being connected to the mounting plate, the main flow edge being connected to the main connecting edge, and a portion of the main flow edge being arc-shaped.

[0013] In one embodiment, the dominant flow edge includes:

[0014] A cutting edge, the cutting edge being connected to the main connecting edge, the cutting edge being located at the water inlet end; and

[0015] A flow-guiding arc edge is connected to the cutting edge and extends from the water inlet end to the water outlet end.

[0016] In one embodiment, at least one of the plurality of mounting plates has a connecting hole that connects the flocculation chamber and the flow guiding channel;

[0017] The connecting hole is provided corresponding to the main flow plate and / or the auxiliary flow plate.

[0018] In one embodiment, the connecting hole includes a main hole and an auxiliary hole, at least one of the plurality of mounting plates has the main hole, and at least one of the plurality of mounting plates has the auxiliary hole;

[0019] Wherein, at least some of the main flow plates are configured to correspond to the main holes, and at least some of the auxiliary flow plates are configured to correspond to the auxiliary holes.

[0020] In one embodiment, the main flow plate is connected to the hole wall of the main hole, and two adjacent main flow plates enclose each other to form the flow channel. The plate surface extension directions of the plurality of main flow plates are arranged at an angle to each other.

[0021] Each of the mounting plates has at least one main hole, and each of the at least one main hole of the mounting plate corresponds to at least one main flow plate.

[0022] In one embodiment, the guide flow plate is connected to the hole wall of the auxiliary hole, and each guide flow plate is disposed in one of the flow guiding channels;

[0023] Each of the mounting plates has at least one auxiliary hole, and each of the at least one auxiliary hole of the mounting plate corresponds to at least one auxiliary flow plate.

[0024] The present invention also proposes a flocculation device, the flocculation device comprising:

[0025] Frame; and

[0026] Multiple flocculation structures as described above are disposed on the base frame, and the multiple flocculation structures are connected and extended sequentially along the horizontal and vertical directions.

[0027] The flocculation structure of this invention includes a main body and a flow guiding structure. The main body includes multiple mounting plates connected to each other, forming multiple sidewalls arranged at included angles. This allows the main body to form a polygonal flocculation cavity, facilitating seamless connection and interlocking of multiple flocculation structures. The multiple mounting plates simultaneously enclose the flocculation cavity, allowing wastewater and chemicals to pass completely through it. Furthermore, the structure of the multiple mounting plates increases the overall structural strength of the flocculation structure, enhancing the lateral impact force of water pressure. The flocculation structure also includes multiple flow guiding structures, each mounted on a mounting plate, and these multiple flow guiding structures... The structure is located in the flocculation chamber. Each flow guiding structure includes a main flow plate and a secondary flow plate. The main flow plate forms a flow guiding channel, allowing wastewater carrying the agent to enter the flocculation chamber. After passing through multiple spirally arranged flow guiding channels, the wastewater carrying the agent generates eddies, further improving the mixing effect of wastewater and agent. This ensures that wastewater and agent are fully mixed and reacted, reducing dead zones and backflow damming, thereby improving the flocculation effect. At the same time, the secondary flow plates are evenly distributed in multiple flow guiding channels, increasing the cutting flow brought by the secondary flow plates, increasing the turbulent area, and also increasing the lateral flow rate, resulting in better coagulation effect.

[0040] To achieve the above objectives, please refer to Figures 1 to 5As shown, the present invention proposes a flocculation structure 100, which includes a main body 1 and a plurality of flow guiding structures 2. The main body 1 includes a plurality of mounting plates 11, which enclose a flocculation cavity 12. Each flow guiding structure 2 is disposed on a mounting plate 11, and the plurality of flow guiding structures 2 are located in the flocculation cavity 12. Each flow guiding structure 2 includes a main flow plate 21 and a secondary flow plate 22. The main flow plate 21 forms a plurality of flow guiding channels 213, and the secondary flow plates 22 are evenly distributed in the plurality of flow guiding channels 213.

[0041] In this embodiment, the flocculation structure 100 is applied in a sewage treatment device. When sewage and the agent used to flocculate the sewage pass through the flocculation structure 100, the flocculation structure 100 can improve the mixing degree of sewage and agent, thereby ensuring that the sewage and agent react fully. The main body 1 in the flocculation structure 100 is the main structural support component. The main body 1 is a frame structure supported on all four sides, and a flocculation cavity 12 for the flow of sewage and agent is formed in the center. That is, the main body 1 can be formed by connecting multiple mounting plates 11 end to end in sequence, or by splicing multiple mesh structures, or by connecting multiple rod-shaped structures end to end in sequence to enclose and form the flocculation cavity 12.

[0042] It is understandable that, such as Figures 1 to 3 As shown, the main body 1 is preferably formed by connecting multiple mounting plates 11 end to end in sequence. The mounting plates 11 enclose and form a flocculation chamber 12 that runs vertically through the body. Simultaneously, the sequential connection of the mounting plates 11 also creates multiple angled sidewalls in the main body 1. That is, the cross-sectional shape of the main body 1 along the direction of the flocculation chamber 12 is polygonal. If there are four mounting plates 11, the cross-sectional shape is square; if there are six mounting plates 11, the cross-sectional shape is regular hexagonal. The number and corresponding shape of other mounting plates 11 are not described here. This arrangement facilitates the connection of adjacent... The two flocculation structures 100 can be directly connected through the mounting plate 11, which improves the connection strength of the flocculation structure 100. The mounting plate 11 is not easy to break, making the flocculation structure 100 more resistant to impact and overload. In addition, in the inner wall of the flocculation chamber 12, the inner angle formed by the two adjacent mounting plates 11 can also cause the sewage entering the flocculation chamber 12 to generate impact turbulence (turbulence) and vortex at the inner angle, so as to disrupt the sewage, avoid the sewage and the agent to maintain a stable laminar flow, improve the turbulence and vortex effect of the sewage flow, improve the mixing degree of sewage and the agent, and improve the flocculation effect.

[0043] In this embodiment, as Figures 1 to 3As shown, the flocculation structure 100 also includes multiple flow guiding structures 2, which are disposed in the flocculation chamber 12. Each flow guiding structure 2 is disposed on a mounting plate 11. The flow guiding structure 2 can be a plate-like structure composed of multiple flow guiding plates or flow guiding vanes, or it can be a flow guiding pipe or flow guiding wall, etc., which are not limited here. Each flow guiding structure 2 includes at least one main flow guiding plate 21 and at least one auxiliary flow guiding plate 22. The area of ​​the plate surface of the main flow guiding plate 21 is larger than the area of ​​the plate surface of the auxiliary flow guiding plate 22. That is, the main flow guiding plate 21 occupies more space in the flocculation chamber 12, while the auxiliary flow guiding plate 22 occupies less space in the flocculation chamber 12. The main flow guiding plate 21 has the main function of guiding and diverting the flow, while the auxiliary flow guiding plate 22 is disposed at intervals between the main flow guiding plates 21 or in the flocculation chamber 12 to play an auxiliary function of guiding and diverting the flow.

[0044] The main flow plate 21 and the auxiliary flow plate 22 are plate-shaped or sheet-shaped. Multiple main flow plates 21 and multiple auxiliary flow plates 22 are disposed in the flocculation chamber 12 and are connected to the inner wall of the flocculation chamber 12 by means of side connection, that is, connected to the side of the mounting plate 11 facing the flocculation chamber 12. The main flow plate 21 and the auxiliary flow plate 22 can be connected to the mounting plate 11 by means of welding, plugging, snap-fitting or screwing, or formed by cutting and bending the side of the mounting plate 11. Each main flow plate 21 is connected to at least one mounting plate 11. That is, the main flow plate 21 can be connected to a single mounting plate 11 by means of side connection, or it can be connected to two adjacent mounting plates 11 by means of side connection, which is not limited here.

[0045] In this embodiment, the main flow plate 21 forms multiple flow channels 213. Two adjacent main flow plates 21 and the plate surface of the mounting plate 11 together form a flow channel 213. The flow channel 213 is part of the flocculation chamber 12. The flow channel 213 is located at the periphery of the flocculation chamber 12 near the mounting plate 11. Each flow channel 213 extends spirally with the center of the flocculation chamber 12 as the axis. After the mixed fluid of sewage and agent enters the flocculation chamber 12, part of the mixed fluid flows out of the flocculation structure 100 through the flow channel 213, and the other part of the mixed fluid flows out through other parts of the flocculation chamber 12. At the same time, at least part of the auxiliary flow plate 22 is provided in the flow channel 213, such as at the inlet and / or outlet of the flow channel 213.

[0046] Understandably, when wastewater containing chemicals enters the flocculation chamber 12 from one end, multiple guide plates can cut and divert the water flow to separate the wastewater and chemicals that were originally unmixed and flowing stably in layers, thereby achieving a finer division of the wastewater flow and improving the mixing degree of wastewater and chemicals. Furthermore, when the wastewater flow containing chemicals enters the spiral-shaped guide channel 213, the mixed fluid will also generate a countercurrent flow, further improving the mixing degree of wastewater and chemicals and thus enhancing the flocculation effect of the wastewater flow.

[0047] In one embodiment, the flocculation structure 100 includes four mounting plates 11 connected end to end to enclose and form a flocculation cavity 12 with a square cross-section; the flocculation structure 100 includes four, six or eight guide plates.

[0048] It is understood that the flocculation structure 100 includes four mounting plates 11, which enclose the main body 1 of a square frame, making the cross-section of the flocculation chamber 12 square along the vertical direction. This arrangement also facilitates the connection of multiple flocculation structures 100 through the mounting plates 11, achieving a seamless connection, avoiding dead flow corners, improving cleaning and self-cleaning capabilities, and preventing blockages. At the same time, the connection strength of multiple flocculation structures 100, as well as their torsional and impact resistance, can be improved through the surface connection of the mounting plates 11, further enhancing the overload capacity of the overall flocculation structure 100.

[0049] Furthermore, four, six, or eight main flow plates 21 can be set in the flocculation chamber 12. The extension directions of the multiple main flow plates 21 are set at an angle to each other, and the tilt angle of the multiple main flow plates 21 gradually changes with the center of the flocculation chamber 12 as the axis, so that the flow channel 213 formed by two adjacent main flow plates 21 is spirally distributed. Of course, depending on the actual sewage flocculation requirements, as well as different situations such as sewage flow rate and amount of reagent added, three, nine, or even more flow plates can be set, which is not limited here.

[0050] Understandably, when wastewater carrying chemicals enters the flocculation chamber 12 from one end, multiple main flow plates 21 can cut and divert the water flow to separate the wastewater and chemicals that were originally unmixed and flowing stably in layers, thereby achieving a finer division of the wastewater flow and improving the mixing degree of wastewater and chemicals. Furthermore, when the wastewater flow carrying chemicals enters the spiral-shaped guide channel 213, the mixed fluid will also generate a countercurrent flow, further improving the mixing degree of wastewater and chemicals and thus enhancing the flocculation effect of the wastewater flow. In addition, when the wastewater flow passes through the auxiliary flow plate 22 located in the guide channel 213, the auxiliary flow plate 22 further cuts and diverts the wastewater flow, further improving the mixing degree of wastewater and chemicals.

[0051] The flocculation structure 100 includes a main body 1 and a flow guiding structure 2. The main body 1 includes multiple mounting plates 11 connected together to form multiple angled sidewalls and to create polygonal flocculation chambers 12. This allows for seamless connection and assembly of the multiple flocculation structures 100. The mounting plates 11 simultaneously enclose the flocculation chambers 12, enabling wastewater and chemicals to pass completely through them. The structure of the mounting plates 11 also increases the overall structural strength of the flocculation structure 100, enhancing the lateral impact force of water pressure. The flocculation structure 100 also includes multiple flow guiding structures 2, each mounted on a mounting plate 11. Each flow guiding structure 2 is located in the flocculation chamber 12. Each flow guiding structure 2 includes a main flow plate 21 and a secondary flow plate 22. The main flow plate 21 forms a flow guiding channel 213, allowing wastewater carrying the agent to enter the flocculation chamber 12. After passing through multiple spirally arranged flow guiding channels 213, the wastewater carrying the agent generates eddies, further enhancing the mixing effect of wastewater and agent. This ensures that wastewater and agent are fully mixed and reacted, reducing dead zones and backflow blockage, thereby improving the flocculation effect. At the same time, the secondary flow plate 22 is evenly distributed in multiple flow guiding channels 213, increasing the cutting flow brought by the secondary flow plate 22, increasing the turbulent area, and also increasing the lateral flow rate, resulting in better coagulation effect.

[0052] In one embodiment, such as Figures 1 to 4 As shown, the plane of the main flow plate 21 of the same flow guiding structure 2 is set at an angle to the plane of the auxiliary flow plate 22; optionally, the planes of the main flow plates 21 of different flow guiding structures 2 are set at angles to each other; optionally, the planes of the auxiliary flow plates 22 of different flow guiding structures 2 are set at angles to each other.

[0053] It is understandable that in the same flow guiding structure 2, the plane of the main flow plate 21 and the plane of the auxiliary flow plate 22 are set at an angle, so that when the sewage flows on the plane of the main flow plate 21, the auxiliary flow plate 22 can also contact and divide part of the sewage flow, thereby disturbing the fluid flowing stably on the main flow plate 21, improving the mixing degree of the medicine and sewage. In addition, from another perspective, the auxiliary flow plate 22 can also cut and subdivide the sewage flow in the flow guiding channel 213 formed by the two main flow plates 21 to improve the turbulence effect of the sewage flow. Furthermore, by setting the planes of the main flow plate 21 and the auxiliary flow plate 22 at an angle, it is also possible to avoid the formation of a stable laminar flow between the main flow plate 21 and the auxiliary flow plate 22.

[0054] It is understandable that the planes of the main flow plates 21 in different flow guiding structures 2 are set at an angle, and the planes of the auxiliary flow plates 22 in different flow guiding structures 2 are set at an angle to each other. This further makes the multiple main flow plates 21 and multiple auxiliary flow plates 22 in the flocculation chamber 12 set at an angle to each other. This not only makes the multiple main flow plates 21 form a spiral flow guiding channel 213, but also makes the auxiliary flow plates 22 further apply an angled flow guiding surface to the flow guiding channel 213, thereby increasing the turbulence of the sewage flow in the flow guiding channel 213 and improving the mixing effect of sewage and chemicals.

[0055] In one embodiment, such as Figure 1 and Figure 4 As shown, the flocculation structure 100 also includes an inlet end 1a and an outlet end 1b. One end of the main flow plate 21 is located at the inlet end 1a, and the other end of the main flow plate 21 is located at the outlet end 1b. The extension direction of the main flow plate 21 is set at an angle to the line connecting the inlet end 1a and the outlet end 1b, so that the flow channel 213 extends spirally from the inlet end 1a to the outlet end 1b.

[0056] In this embodiment, the flocculation chamber 12 extends vertically through the entire structure, allowing wastewater containing the reagent to enter the flocculation chamber 12 from the inlet end 1a and exit from the outlet end 1b. One end of the main flow plate 21 is mounted on the main body 1 and located at the inlet end 1a of the flocculation chamber 12, while the other end is mounted on the main body 1 and located at the outlet end 1b of the flocculation chamber 12. The extension direction of the main flow plate 21 is at an angle to the extension direction of the mounting plate 11, and the extension direction of the main flow plate 21 is also at an angle to the line connecting the inlet end 1a to the outlet end 1b of the flocculation chamber 12, thus forming a spirally extending guide channel 213.

[0057] Understandably, multiple guide channels 213 spiral around the central axis of the flocculation chamber 12 in the same direction. The main flow plate 21 is located at the end face of the inlet end 1a, which can cut the sewage flow entering the flocculation chamber 12, dividing the original complete water flow into multiple smaller water flows, which then enter a guide channel 213 respectively. This disrupts the stable sewage flow, thereby increasing the mixing degree of the agent and sewage inside. Furthermore, when the sewage flow carrying the agent enters the guide channel 213, the spirally rotating sewage flow generates more countercurrent flow. That is, the sewage flow will tumble along the guide channel 213 under the action of the main flow plate 21, further enhancing the mixing and reaction degree of the agent and sewage, and improving the flocculation effect on the sewage.

[0058] In one embodiment, multiple main flow plates 21 further enclose a DC cavity 13, which is connected to multiple flow channels 213, and the DC cavity 13 and the multiple flow channels 213 together form a flocculation cavity 12.

[0059] In this embodiment, the DC cavity 13 is located in the center of the flocculation cavity 12, that is, the side of the multiple main flow plates 21 away from the connecting mounting plate 11, which together enclose the DC cavity 13, so that the DC cavity 13 extends along the direction from the water inlet end 1a to the water outlet end 1b of the flocculation cavity 12, and the flocculation cavity 12 is also connected to multiple flow channels 213. The cavity shape of the flocculation cavity 12 is related to the shape of the side of the flow plate away from the mounting plate 11. In one embodiment, the side of the main flow plate 21 away from the mounting plate 11 is an arc that is concave inward towards the mounting plate 11, so that the cavity of the DC cavity 13 is cylindrical.

[0060] Understandably, when the wastewater containing the chemicals enters the flocculation chamber 12, on the one hand, the main flow plate 21 and the guide channel 213 need to turbulent the wastewater flow and chemicals to improve the mixing effect. On the other hand, some of the wastewater flow also needs to flow through the direct flow chamber 13 through the flocculation structure 100 to ensure the cross-sectional water flow rate of the flocculation structure 100 per unit time, so that the water flow can quickly flow through the flocculation chamber 12 and avoid obstructing the flow of wastewater due to the setting of the main flow plate 21, thus ensuring smooth water flow.

[0061] In one embodiment, such as Figure 2 and Figure 3 As shown, the main flow plate 21 includes a main connecting edge 211 and a main flow edge 212. The main connecting edge 211 is connected to the mounting plate 11, and the main flow edge 212 is connected to the main connecting edge 211. Part of the main flow edge 212 is arc-shaped.

[0062] It is understood that the main flow guide plate 21 is a plate-shaped or sheet-shaped structure. The flow guide plate has a plate surface for carrying water flow and side edges around the plate surface. The side edges include a main connecting edge 211 for connecting to the mounting plate 11 and a main flow guide edge 212 connected to the main connecting edge 211. The main connecting edge 211 is connected to the plate surface of at least one mounting plate 11. If there are two main connecting edges 211, one main connecting edge 211 is connected to one of two adjacent mounting plates 11, and the other main connecting edge 211 is connected to the other of two adjacent mounting plates 11. This makes the placement of the flow guide plates more flexible when multiple flow guide plates are placed in the flocculation chamber 12. They can be placed on the plate surface of the mounting plate 11 or at the angle formed by adjacent mounting plates 11, which can increase the number of flow guide plates and thus increase the number of flow guide channels 213, improve the degree of subdivision and cutting of the sewage flow, and improve the mixing degree of the agent and sewage.

[0063] Meanwhile, a main flow edge 212 is formed on the side of the main flow plate 21 away from the mounting plate 11. The main flow edge 212 is partially concave in an arc shape towards the mounting plate 11, so that the arc-shaped parts of multiple main flow edges 212 together enclose and form a DC cavity 13. Furthermore, the main flow edge 212 can also be set as a straight edge, which is not limited here.

[0064] In one embodiment, such as Figure 2 and Figure 3 As shown, the main flow edge 212 includes a cutting edge 2121 and a flow guiding arc edge 2122. The cutting edge 2121 is connected to the main connecting edge 211 and is located at the water inlet end 1a. The flow guiding arc edge 2122 is connected to the cutting edge 2121 and extends from the water inlet end 1a to the water outlet end 1b.

[0065] In this embodiment, one end of the cutting edge 2121 is connected to the main connecting edge 211, and the other end of the cutting edge 2121 is connected to the guide arc edge 2122. The cutting edge 2121 is located at the water inlet 1a of the flocculation chamber 12. The guide arc edge 2122 extends approximately along the direction from the water inlet 1a to the water outlet 1b and is set at an angle to the through direction of the flocculation chamber 12. At the same time, the extension direction of the guide arc edge 2122 is also set at an angle to the extension direction of the main connecting edge 211. Furthermore, the guide arc edge 2122 is concave towards the mounting plate 11.

[0066] It is understood that the cutting edge 2121 is located at the inlet end 1a of the flocculation chamber 12. Simultaneously, the cutting edge 2121 extends from the mounting plate 11 towards the center of the flocculation chamber 12, causing the cutting edges 2121 of the multiple main flow plates 21 to cut the periphery of the inlet end 1a of the flocculation chamber 12 near the mounting plate 11 into multiple regions. Each region serves as the inlet of a flow channel 213, and all regions are connected to the direct flow chamber 13. When wastewater containing chemicals enters the flocculation chamber 12 from the inlet end 1a, the multiple cutting edges 2121 simultaneously cut the wastewater flow. The wastewater flow is divided into multiple streams, which then enter multiple guide channels 213. This design disrupts the stable flow of the wastewater containing chemicals, allowing the chemicals to disperse as much as possible and mix and react fully with the wastewater, thus effectively improving the flocculation effect. After the wastewater flow is divided, at the outlet 1b of the flocculation chamber 12, which is the other end of the guide plate away from the cutting edge 2121, the multiple wastewater streams flowing out of the guide channels 213 collide and merge again, forming an impact flow, further enhancing the mixing effect.

[0067] It is understandable that the extension direction of the guide arc edge 2122 is also set at an angle with the extension direction of the main connecting edge 211, so that the surface of the main flow plate 21 is also set as an undulating arc surface, such as tilting from the main connecting edge 211 to the guide arc edge 2122, or tilting from the guide arc edge 2122 to the main connecting edge 211. At the same time, the extension direction of the guide arc edge 2122 and the extension direction of the main connecting edge 211 can also be set as a constantly changing structure, so that the surface of the main flow plate 21 is tilted between the main connecting edge 211 and the guide arc edge 2122, and also has undulations along the extension direction of the main flow plate 21, thereby forming a constantly changing curved surface on the surface of the main flow plate 21, effectively improving the turbulence effect when the sewage flows on the surface of the main flow plate 21, and improving the mixing effect of the agent and the sewage flow.

[0068] In one embodiment, the main flow edge 212 further includes a flow guide tail edge, which is connected to the end of the flow guide arc edge 2122 away from the cutting edge 2121. The flow guide tail edge is located at the water outlet 1b, and the flow guide plate is arranged in a straight or arc-shaped surface from the cutting edge 2121 to the flow guide tail edge.

[0069] It is understood that the guide tail edge is located at the end of the main flow plate 21 away from the cutting edge 2121, that is, the guide tail edge is located at the outlet end 1b of the flocculation chamber 12. In one embodiment, one end of the guide tail edge is connected to the main connecting edge 211, and the other end of the guide tail edge is connected to the guide arc edge 2122. By setting the guide tail edge and adjusting the angle between the guide tail edge and the central axis of the mounting plate 11 and / or the flocculation chamber 12, the curvature of the main flow plate 21 can be adjusted, thereby adjusting the flow direction of the sewage flowing out of the guide channel 213, such as flowing out in a vertically downward direction or spiraling out in a direction around the central axis of the flocculation chamber 12, so as to flexibly set the flow speed of the sewage in the guide channel 213 and the impact collision angle when flowing out of the guide channel 213, thereby improving the mixing effect.

[0070] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, at least one of the multiple mounting plates 11 has a connecting hole 111, which connects the flocculation chamber 12 and the flow guiding channel 213; wherein, the connecting hole 111 is provided corresponding to the main flow plate 21 and / or the auxiliary flow plate 22.

[0071] In this embodiment, at least one of the mounting plates 11 has a connecting hole 111 that connects to the flocculation chamber 12. Simultaneously, the connecting hole 111 is also connected to the guide channel 213. That is, at least one connecting hole 111 is provided around the periphery of the frame of the flocculation structure 100, allowing a portion of the wastewater flow to enter the guide channel 213 in a transverse flow manner through the connecting hole 111. The portion of the wastewater flow entering the guide channel 213 continues to flow transversely into the flocculation chamber 12, while the other portion flows along the spiral guide channel 213 towards the flocculation chamber. The wastewater flows out from the lower end of chamber 12, while some wastewater still enters chamber 12 from the upper end. This allows the horizontally flowing wastewater to collide with the wastewater flowing along the penetrating direction of chamber 12, generating more turbulence. This improves the mixing and reaction of wastewater and chemicals, enhances the flocculation effect, and effectively increases the flow state of wastewater, such as horizontal flow, vertical flow, and eddies, thereby increasing the probability of impact and collision within the wastewater flow, thus improving the mixing and reaction of chemicals and wastewater.

[0072] Furthermore, the connecting hole 111 provided on the mounting plate 11 can be individually provided for at least one main flow plate 21. That is, at least one main flow plate 21 is connected to the hole wall of the connecting hole 111. In the case of multiple main flow plates 21, the main connecting edges 211 of the multiple main flow plates 21 are respectively connected to the hole wall of the connecting hole 111, and the main flow plates 21 extend towards the flocculation chamber 12. In one embodiment, at least one main flow plate 21 can completely cover the connecting hole 111. That is, when the mounting plate 11 forms the connecting hole 111, it forms the main flow plate 21. The part of the mounting plate 11 after direct bending and cutting forms the main flow plate 21, thereby effectively saving materials, improving the processing and manufacturing efficiency of the flocculation structure 100, reducing costs, improving the mechanical stability and uniformity of the product, and the overall structure of the equipment has higher impact resistance and torque resistance than the welded main flow plates.

[0073] Meanwhile, the connecting hole 111 can also be set to correspond to at least one auxiliary flow plate 22, or to correspond to both the main flow plate 21 and the auxiliary flow plate 22 at the same time, which will not be elaborated here.

[0074] In another embodiment of the present invention, each mounting plate 11 is provided with a connecting hole 111, such that a flocculation structure 100 has the same number of connecting holes 111 as the mounting plate 11. At the same time, each mounting plate 11 is provided with at least one connecting hole 111, such as one, two or more connecting holes 111, and the connecting hole 111 corresponds to one of the multiple flow channels 213.

[0075] Understandably, each mounting plate 11 is provided with a connecting hole 111, which is connected to the flocculation chamber 12 through the flow guide channel 213. This allows the sewage flow to enter the flow guide channel 213 from the periphery of the flocculation structure 100. Part of the sewage flows laterally into the flow guide channel 213 and into the flocculation chamber 12, while the other part flows out along the flow guide channel 213 in the penetrating direction of the flocculation chamber 12 towards the lower end of the flocculation structure 100. This effectively increases the flow rate of sewage into the flocculation chamber 12. Furthermore, the connecting hole 111 also increases the lateral flow of sewage, creating impact and collision with the sewage flow flowing in along the penetrating direction of the flocculation chamber 12, thereby increasing the turbulence of the sewage and improving the mixing degree of the sewage flow and the agent. At the same time, the lateral flow rate of the flocculation structure 100 can be adjusted according to the number and diameter of the connecting holes 111 on the mounting plate 11.

[0076] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the connecting hole 111 includes a main hole 1111 and an auxiliary hole 1112. At least one of the multiple mounting plates 11 has a main hole 1111 and at least one of the multiple mounting plates 11 has an auxiliary hole 1112. At least a portion of the main flow plates 21 are provided corresponding to the main hole 1111, and at least a portion of the auxiliary flow plates 22 are provided corresponding to the auxiliary hole 1112.

[0077] It is understood that at least one of the multiple mounting plates 11 has a main hole 1111, that is, one of the multiple mounting plates 11 may have a main hole 1111, or all of the multiple mounting plates 11 may have a main hole 1111, and the main holes 1111 are all connected to the flocculation chamber 12. At the same time, at least one of the multiple mounting plates 11 has an auxiliary hole 1112. The auxiliary hole 1112 may be opened on one mounting plate 11, or it may be installed on multiple or even all of the mounting plates 11, and the auxiliary holes 1112 are also all connected to the flocculation chamber 12.

[0078] Furthermore, the main orifice 1111 and the auxiliary orifice 1112 can be disposed on the same mounting plate 11 or on different mounting plates 11. At least a portion of the main flow guide plates 21 are disposed corresponding to the main orifice 1111, and at least a portion of the auxiliary flow guide plates 22 are disposed corresponding to the auxiliary orifice 1112. That is, multiple flow guide structures 2 disposed in the flocculation chamber 12 are all disposed corresponding to the main orifice 1111 and the auxiliary orifice 1112 opened on the mounting plate 11, such that each main orifice 1111 corresponds to at least one main flow guide plate 21, and each auxiliary orifice 1112 corresponds to at least one main flow guide plate 21. The orifice 1112 is provided with at least one auxiliary flow plate 22. This arrangement allows the wastewater containing the reagent to be guided and turbulent by the main flow plate 21 when it enters the flocculation chamber 12 through the main orifice 1111, and to be guided and turbulent by the auxiliary flow plate 22 when it enters the flocculation chamber 12 through the auxiliary orifice 1112. This not only increases the lateral flow rate of the wastewater, but also enhances the turbulence effect on the wastewater through the main flow plate 21 and the auxiliary flow plate 22, thereby improving the mixing effect of the reagent and the wastewater.

[0079] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the main flow plate 21 is connected to the hole wall of the main hole 1111, and two adjacent main flow plates 21 form a flow channel 213. The plate surface extension directions of the multiple main flow plates 21 are arranged at an angle to each other. Each mounting plate 11 has at least one main hole 1111, and at least one main hole 1111 of each mounting plate 11 corresponds to at least one main flow plate 21.

[0080] It is understandable that each mounting plate 11 can have one main hole 1111 or multiple main holes 1111. The number and area of ​​main holes 1111 on the mounting plate 11 can be flexibly adjusted according to the actual size of the sewage treatment area, the actual chemical content, the sewage state, and the flocculation time, thereby adjusting the flow rate and velocity of the sewage flow in the lateral direction and flexibly adjusting the mixing effect of the chemical and sewage flow.

[0081] In this configuration, each mounting plate 11 has at least one main hole 1111 corresponding to one main flow plate 21. That is, if there is one main hole 1111 on the same mounting plate 11, the main hole 1111 can correspond to one main flow plate 21 or multiple main flow plates 21. When one main hole 1111 corresponds to one main flow plate 21, the shape and area of ​​the main flow plate 21 are completely consistent with the shape and area of ​​the orifice of the main hole 1111. When one main hole 1111 corresponds to multiple main flow plates 21, the shape and area of ​​the multiple main flow plates 21 after being assembled together are consistent with the shape and area of ​​the orifice of the main hole 1111. The main flow plate 21 is made completely identical so that it can be directly formed from the main hole 1111 after being cut and bent. At this time, the main flow edge 212 of the main flow plate 21 is integrally formed and connected with the hole wall of the main hole 1111. This not only effectively saves materials, but also reduces the processing difficulty and improves the processing efficiency. It also helps to improve the overall impact resistance of the flocculation structure 100. In addition, multiple main holes 1111 can be provided on the same mounting plate 11. At least one of the multiple main holes 1111 can be connected to the main flow plate 21, or all of the multiple main holes 1111 can be connected to one or more main flow plates 21. This is not limited here.

[0082] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the guide flow plate 22 is connected to the hole wall of the auxiliary hole 1112, and each guide flow plate 22 is provided in a flow channel 213; each mounting plate 11 has at least one auxiliary hole 1112, and each mounting plate 11 has at least one auxiliary hole 1112 corresponding to at least one guide flow plate 22.

[0083] It is understandable that each mounting plate 11 can have one or more auxiliary holes 1112. The number and area of ​​auxiliary holes 1112 on the mounting plate 11 can be flexibly adjusted according to the actual size of the sewage treatment area, the actual chemical content, the sewage state, and the flocculation time, thereby adjusting the flow rate and velocity of the sewage flow in the lateral direction and flexibly adjusting the mixing effect of the chemical and sewage flow.

[0084] In this configuration, each mounting plate 11 has at least one auxiliary hole 1112 corresponding to one guide flow plate 22. That is, if there is one auxiliary hole 1112 on the same mounting plate 11, the auxiliary hole 1112 can correspond to one guide flow plate 22 or multiple guide flow plates 22. When one auxiliary hole 1112 corresponds to one guide flow plate 22, the shape and area of ​​the guide flow plate 22 are completely consistent with the shape and area of ​​the orifice of the auxiliary hole 1112. When one auxiliary hole 1112 corresponds to multiple guide flow plates 22, the shape and area of ​​the multiple guide flow plates 22 after being assembled together are consistent with the shape and area of ​​the orifice of the auxiliary hole 1112. The dimensions are completely consistent so that the guide flow plate 22 can be directly formed from the auxiliary hole 1112 after cutting and bending. At this time, the guide flow edge of the guide flow plate 22 is integrally formed and connected with the hole wall of the auxiliary hole 1112. This not only effectively saves materials, but also reduces the processing difficulty and improves the processing efficiency. It also helps to improve the overall impact resistance of the flocculation structure 100. In addition, multiple auxiliary holes 1112 can be provided on the same mounting plate 11. At least one of the multiple auxiliary holes 1112 can be connected to the guide flow plate 22, or all of the multiple auxiliary holes 1112 can be connected to one or more guide flow plates 22. This is not limited here.

[0085] The present invention also proposes a flocculation device 300, such as... Figure 5 As shown, the flocculation device 300 includes a base frame 301 and a plurality of the aforementioned flocculation structures 100. The plurality of flocculation structures 100 are disposed on the base frame 301 and are sequentially connected and extended in the horizontal and vertical directions to form a flocculation layer structure. The specific structure of the flocculation structure 100 is as described in the foregoing embodiments. Since this flocculation device 300 adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, and will not be described in detail here.

[0086] Understandably, multiple flocculation structures 100 are arranged in an array in both the horizontal and vertical directions, that is, multiple flocculation structures 100 extend in two directions forming an angle with each other along the horizontal plane to form a single-layer flocculation layer structure. The array arrangement of the flocculation layer structure is achieved by connecting the mounting plates 11 in the multiple flocculation structures 100 to each other. For example, two adjacent flocculation structures 100 can be fixedly connected by welding, screwing, etc., or they can be movably connected by snap-fit, plug-in, etc., or they can share the same mounting plate 11. At the same time, the number of mounting plates 11 in each flocculation structure 100 can be four. Six or eight flocculation structures 100 can be seamlessly connected through the mounting plate 11. Taking the number of mounting plates 11 as an example, the cross-section of the main body 1 of the flocculation structure 100 is square, and the multiple flocculation structures 100 extend and are arranged in two mutually perpendicular directions on the horizontal plane. This arrangement can ensure that both sewage and chemicals can flow through the flocculation chamber 12, avoiding dead corners at the connection points of traditional flocculation structures 100, which would lead to the accumulation of sludge and debris, as well as uneven mixing of sewage and chemicals. This makes the flocculation equipment 300 less prone to clogging and effectively improves the self-cleaning ability of the flocculation equipment 300.

[0087] Furthermore, the single-layer flocculation layer structures are interconnected in the vertical direction by mounting plates 11 to form multi-layer flocculation layer structures, which are then combined to form flocculation equipment 300. The flocculation chambers 12 of the upper and lower multi-layer flocculation layer structures are connected in the vertical direction, so that the flocculation equipment 300 forms multiple independent and through flocculation channels.

[0088] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
