[0039] Please refer to Figures 1 to 7 As shown, to achieve the above object, the present utility model provides a flocculation structure 100. The flocculation structure 100 includes a main body 1 and a plurality of flow guide plates 2. The main body 1 includes a plurality of mounting plates 11. The plurality of mounting plates 11 are connected to each other so that the main body 1 forms a plurality of side walls arranged at an angle. The plurality of mounting plates 11 enclose a flocculation chamber 12. The plurality of flow guide plates 2 are arranged in the flocculation chamber 12. Each flow guide plate 2 is connected to at least one mounting plate 11. An adjacent two flow guide plates 2 and the mounting plate 11 enclose a flow guide channel 2a. Wherein, each flow guide channel 2a extends in a spiral shape with the center of the flocculation chamber 12 as the axis.

[0040] In this embodiment, the flocculation structure 100 is applied to a sewage treatment device. When sewage and a chemical agent for flocculating the sewage pass through the flocculation structure 100, the flocculation structure 100 can improve the mixing degree of the sewage and the chemical agent, thereby ensuring sufficient reaction between the sewage and the chemical agent. 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 sides and forms a flocculation chamber 12 for flowing sewage and the chemical agent in the center. That is, the main body 1 can be formed by sequentially connecting the plurality of mounting plates 11 end to end, or can be formed by splicing a plurality of mesh structures, or can also be formed by sequentially connecting a plurality of rod-shaped structures end to end to enclose the flocculation chamber 12.

[0041] It can be understood that the main body 1 is preferably formed by sequentially connecting a plurality of mounting plates 11 end to end. The mounting plates 11 enclose a flocculation cavity 12 that penetrates up and down. At the same time, the head and tail of the mounting plates 11 are sequentially connected, which also makes the main body 1 form a plurality of side walls with included angles. That is, the cross-sectional shape of the main body 1 along the penetration direction of the flocculation cavity 12 is a polygon. When the number of mounting plates 11 is 4, the cross-sectional shape is a square. When the number of mounting plates 11 is 6, the cross-sectional shape is a regular hexagon. The number and corresponding shapes of the remaining mounting plates 11 will not be elaborated here. In this way, it is convenient for two adjacent flocculation structures 100 to be connected through the mounting plates 11, improving the connection strength of the flocculation structure 100. The mounting plates 11 are not easily broken, making the flocculation structure 100 have stronger impact resistance and overload capacity. Moreover, in the inner wall of the flocculation cavity 12 of the main body 1, the inner angles formed by two adjacent mounting plates 11 can also cause the sewage entering the flocculation cavity 12 to generate impact turbulence (turbulence) and vortices at the inner angles, so as to disrupt the sewage, prevent the sewage and the reagent from maintaining a stable laminar flow, improve the turbulent flow and eddy current effects of the sewage flow, improve the mixing degree of the sewage and the reagent, and improve the flocculation effect.

[0042] In this embodiment, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, the flocculation structure 100 further includes a plurality of flow guide plates 2. The flow guide plates 2 are in a plate shape or a sheet shape. A plurality of flow guide plates 2 are arranged in the flocculation cavity 12 and are connected to the inner wall of the flocculation cavity 12 through the side edges of the flow guide plates 2, that is, connected to the side of the mounting plate 11 facing the flocculation cavity 12. The flow guide plates 2 can be connected to the mounting plate 11 in forms such as welding, plugging, clamping, or screwing. Among them, each flow guide plate 2 is connected to at least one mounting plate 11, that is, the flow guide plate 2 can be separately connected to a mounting plate 11 through the side edge, or can be connected to two adjacent mounting plates 11 through the side edge, which is not limited here.

[0043] In this embodiment, two adjacent flow guide plates 2 and the plate surface of the mounting plate 11 to which the flow guide plates 2 are connected jointly enclose a flow guide channel 2a. The flow guide channel 2a is a part of the flocculation cavity 12. The flow guide channel 2a is located at the periphery of the flocculation cavity 12 close to the mounting plate 11, and each flow guide channel 2a extends in a spiral shape with the center of the flocculation cavity 12 as the axis. After the mixed fluid of sewage and reagent enters the flocculation cavity 12, part of the mixed fluid flows out of the flocculation structure 100 through the flow guide channel 2a, and the other part of the mixed fluid flows out through other parts of the flocculation cavity 12.

[0044] It can be understood that when the sewage with the medicament enters the flocculation chamber 12 from one end of the flocculation chamber 12, the multiple flow guiding plates 2 can cut and divert the water flow, so as to cut the originally unmixed and stably stratified flowing sewage and medicament, realize the subdivision of the sewage flow, improve the mixing degree of the sewage and the medicament, and moreover, when the sewage flow with the medicament enters the spiral flow guiding channel 2a, an opposite flow will also be generated in the mixed fluid, further improving the mixing degree of the sewage and the medicament, so as to improve the flocculation effect of the sewage flow.

[0045] The flocculation structure 100 includes a main body 1 and multiple flow guiding plates 2. The main body 1 includes multiple mounting plates 11, and the multiple mounting plates 11 are connected to each other so that the main body 1 forms multiple side walls arranged at an angle, so that the main body 1 can form a flocculation chamber 12 with a polygonal cross-section, which is convenient for seamless splicing and connection of multiple flocculation structures 100. The multiple mounting plates 11 enclose the flocculation chamber 12 at the same time, so that the sewage and the medicament can completely pass through the flocculation chamber 12, and the structure of the multiple mounting plates 11 also makes the overall structural strength of the flocculation structure 100 higher, enhancing the lateral impact force of the water pressure; the multiple flow guiding plates 2 are arranged in the flocculation chamber 12, and each flow guiding plate 2 is connected to at least one mounting plate 11, and an adjacent two flow guiding plates 2 and the mounting plate 11 enclose a flow guiding channel 2a; wherein, each flow guiding channel 2a extends in a spiral shape with the center of the flocculation chamber 12 as the axis. When the sewage flow with the medicament enters the flocculation chamber 12, the multiple flow guiding plates 2 can cut the sewage flow to disrupt the laminar flow of the sewage, improve the mixing effect of the sewage and the medicament, and at the same time, after passing through the multiple spirally arranged flow guiding channels 2a, the sewage flow with the medicament generates a vortex, making the reaction flow unidirectionally, without dead ends and backflow blockage phenomena, further improving the mixing effect of the sewage and the medicament, so that the sewage and the medicament are fully mixed and reacted to improve the flocculation effect.

[0046] In an embodiment, the flocculation chamber 12 includes a water inlet end 121 and a water outlet end 122. One end of the flow guiding plate 2 is arranged at the water inlet end 121, and the other end of the flow guiding plate 2 is arranged at the water outlet end 122. The extending direction of the flow guiding plate 2 forms an angle with the connecting line direction from the water inlet end 121 to the water outlet end 122, so that the flow guiding channel 2a extends in a spiral shape from the water inlet end 121 to the water outlet end 122.

[0047] In this embodiment, as Figures 1 to 3 、 Figure 5 and Figure 6As shown, the flocculation chamber 12 penetrates vertically up and down, so that the sewage flow with the agent enters the flocculation chamber 12 from the water inlet end 121 and flows out of the flocculation chamber 12 from the water outlet end 122. Among them, one end of the flow guide plate 2 is arranged on the main body 1 and is located at the water inlet end 121 of the flocculation chamber 12, and the other end of the flow guide plate 2 is arranged on the main body 1 and is located at the water outlet end 122 of the flocculation chamber 12. Moreover, the extending direction of the plate surface of the flow guide plate 2 forms an angle with the extending direction of the plate surface of the mounting plate 11, and the extending direction of the plate surface of the flow guide plate 2 also forms an angle with the connecting line direction of the flocculation chamber 12 from the water inlet end 121 to the water outlet end 122, so as to form a spiral extending flow guide channel 2a.

[0048] It can be understood that multiple flow guide plates 2 are arranged at approximately the same inclination angle, so that multiple flow guide channels 2a spiral around the central axis of the flocculation chamber 12 in the same direction. The end surface of the flow guide plate 2 at the water inlet end 121 can cut the sewage flow entering the flocculation chamber 12, cut the original complete water flow into multiple finer water flows, and respectively enter a flow guide channel 2a, so as to realize the destruction of the stably flowing sewage flow, improve the mixing degree of the agent and the sewage inside it. Moreover, when the sewage flow with the agent enters the flow guide channel 2a, more countercurrents are generated by the spirally rotating sewage flow, that is, the sewage flow will roll along the flow guide channel 2a under the action of the flow guide plate 2, so as to further improve the mixing and reaction degree of the agent and the sewage and enhance the flocculation effect on the sewage.

[0049] In an embodiment, multiple flow guide plates 2 also enclose to form a direct current chamber 2b. The direct current chamber 2b is communicated with multiple flow guide channels 2a, and the direct current chamber 2b and multiple flow guide channels 2a together form the flocculation chamber 12.

[0050] In this embodiment, as Figures 1 to 6 shown, the direct current chamber 2b is located in the center of the flocculation chamber 12, that is, the side edges of multiple flow guide plates 2 far from the side connected to the mounting plate 11 together enclose to form the direct current chamber 2b, so that the direct current chamber 2b extends along the direction from the water inlet end 121 to the water outlet end 122 of the flocculation chamber 12. Moreover, the flocculation chamber 12 is also communicated with multiple flow guide channels 2a. The cavity shape of the flocculation chamber 12 is related to the shape of the side edge of the flow guide plate 2 far from the mounting plate 11. In an embodiment, the side edge of the flow guide plate 2 far from the mounting plate 11 is an arc concave inward toward the mounting plate 11, so that the cavity of the direct current chamber 2b is cylindrical.

[0051] It can be understood that when the sewage flow with the medicament enters the flocculation chamber 12, on the one hand, the sewage flow and the medicament need to be turbulently flowed through the guide plate 2 and the diversion channel 2a to improve the mixing effect. On the other hand, part of the sewage flow also needs to flow through the direct flow chamber 2b past the flocculation structure 100 to ensure the cross-sectional water throughput rate of the flocculation structure 100 per unit time, ensure that the water flow can quickly flow through the flocculation chamber 12, avoid hindering the flow of the sewage flow due to the installation of the guide plate 2, and ensure smooth water flow.

[0052] In one embodiment, the guide plate 2 includes a connecting side 21 and a diversion side 22. The connecting side 21 and the diversion side 22 are connected. The connecting side 21 is used to connect the mounting plate 11, and part of the diversion side 22 is arranged in an arc shape. The arc-shaped parts of the plurality of diversion sides 22 together enclose the direct flow chamber 2b.

[0053] It can be understood that as Figures 1 to 6 shown, the guide plate 2 is a plate-shaped or sheet-shaped structure. The guide plate 2 has a plate surface for carrying the water flow through, and side edges arranged around the plate surface. The side edges include a connecting side 21 for connecting to the mounting plate 11 and a diversion side 22 connected to the connecting side 21. Among them, the connecting side 21 is connected to the plate surface of at least one mounting plate 11. For example, if the connecting side 21 includes two, one connecting side 21 is connected to one of the adjacent two mounting plates 11, and the other connecting side 21 is connected to the other of the adjacent two mounting plates 11. When a plurality of guide plates 2 are placed in the flocculation chamber 12, the placement position of the guide plate 2 is more flexible. It can be arranged on the plate surface of the mounting plate 11 or at the included angle formed by the adjacent mounting plates 11, which can increase the number of guide plates 2 placed, thereby increasing the number of diversion channels 2a and improving the degree of subdivision and cutting of the sewage flow to improve the mixing degree of the medicament and the sewage.

[0054] At the same time, a diversion side 22 is formed on the side of the guide plate 2 away from the mounting plate 11. Part of the diversion side 22 is arranged in an arc shape concave towards the mounting plate 11, so that the arc-shaped parts of the plurality of diversion sides 22 together enclose the direct flow chamber 2b. And the diversion side 22 can also be set as a straight edge, which is not limited here.

[0055] In one embodiment, the connecting side 21 includes a first side 211 and a second side 212. The extending direction of the first side 211 and the extending direction of the second side 212 are arranged at an included angle; among them, the first side 211 and the second side 212 are respectively connected to two connected mounting plates 11 and join the corner formed by the two mounting plates 11.

[0056] In this embodiment, as Figures 1 to 4As shown, the first side 211 and the second side 212 are directly connected, and one end of the first side 211 away from the second side 212 and one end of the second side 212 away from the first side 211 are both connected to the diversion side 22. Among them, the first side 211 is connected to one of two adjacent mounting plates 11, and the second side 212 is connected to the other of the two adjacent mounting plates 11, so that the first side 211 and the second side 212 can connect the corner formed by the two mounting plates 11.

[0057] It can be understood that the first side 211 is connected to the end of the mounting plate 11 closer to the water inlet end 121, and one end of the second side 212 is connected to the first side 211, so that the second side 212 extends from the end closer to the water inlet end 121 along the plate surface direction of the mounting plate 11 towards the end closer to the water outlet end 122. At the same time, the extending direction of the second side 212 is set at an angle with the penetrating direction of the flocculation chamber 12, so that the plate surface of the deflector 2, especially the partial area of the deflector 2 provided with the second side 212, can form an inclined state that is at an angle with both the plate surface of the mounting plate 11 and the penetrating direction of the flocculation chamber 12, so that the diversion channel 2a can form a spiral structure arranged around the central axis of the flocculation chamber 12, and the sewage flow entering the diversion channel 2a can flow, tumble and mix along the spiral channel to improve the flocculation effect.

[0058] In one embodiment, the diversion side 22 includes a cutting edge 221 and a diversion arc edge 222. The cutting edge 221 is connected to the connecting side 21. The cutting edge 221 is located at the water inlet end 121. The diversion arc edge 222 is connected to the cutting edge 221. The diversion arc edge 222 extends from the water inlet end 121 to the water outlet end 122 and encloses to form a direct current chamber 2b.

[0059] In this embodiment, as Figures 1 to 6 shown, one end of the cutting edge 221 is connected to the connecting side 21. Specifically, it can be connected to the first side 211 of the connecting side 21. The other end of the cutting edge 221 is connected to the diversion arc edge 222. Among them, the cutting edge 221 is located at the position of the water inlet end 121 of the flocculation chamber 12. The diversion arc edge 222 extends generally along the direction from the water inlet end 121 to the water outlet end 122 and is set at an angle with the penetrating direction of the flocculation chamber 12. At the same time, the extending direction of the diversion arc edge 222 is also set at an angle with the extending direction of the second side 212 described above, and the diversion arc edge 222 is concave towards the mounting plate 11 side.

[0060] It can be understood that the cutting edge 221 is provided at the water inlet end 121 of the flocculation chamber 12. At the same time, the cutting edge 221 starts from the mounting plate 11 and extends towards the central position of the flocculation chamber 12, so that the cutting edges 221 of the plurality of guide plates 2 cut the periphery of the water inlet end 121 of the flocculation chamber 12 adjacent to the mounting plate 11 into a plurality of regions. Each region is the entrance of a diversion channel 2a, and the plurality of regions are all communicated with the direct current chamber 2b. When the sewage flow with medicine enters the flocculation chamber 12 from the water inlet end 121, the plurality of cutting edges 221 cut and subdivide the sewage flow at the same time, dividing the originally complete sewage flow into multiple water flows, which respectively enter the plurality of diversion channels 2a. With such a setting, the stable flow state of the sewage flow with medicine can be disrupted, and the medicine in the sewage flow can be dispersed as much as possible to be fully mixed and reacted with the sewage flow, effectively improving the flocculation effect. After the sewage flow is divided, at the water outlet end 122 of the flocculation chamber 12, that is, the other end of the guide plate 2 away from the cutting edge 221, the multiple sewage flows flowing out of the diversion channels 2a collide and converge again to form an impact flow, further improving the mixing effect.

[0061] It can be understood that the extending direction of the guiding arc edge 222 is also set at an angle with the extending direction of the above-mentioned second side edge 212, so that the plate surface of the guide plate 2 is also set as a fluctuating arc surface, such as tilting from the second side edge 212 to the guiding arc edge 222, or tilting from the guiding arc edge 222 to the second side edge 212. At the same time, the extending direction of the guiding arc edge 222 and the extending direction of the second side edge 212 can also be set as a continuously changing structure, so that while the plate surface of the guide plate 2 is inclined between the second side edge 212 and the guiding arc edge 222, there are also fluctuations along the extending direction of the guide plate 2, so as to form a continuously changing curved surface on the surface of the guide plate 2, effectively improving the turbulent flow effect when the sewage flow flows on the surface of the guide plate 2 and improving the mixing effect of the medicine and the sewage flow.

[0062] In one embodiment, the water inlet end 121 forms a water inlet horizontal plane, and the cutting edge 221 is flush with the water inlet horizontal plane; optionally, the extending direction of the cutting edge 221 is set at an angle with the plate surface direction of the mounting plate 11; optionally, the water inlet end 121 forms a water inlet horizontal plane, and the cutting edge 221 is set at an angle with the water inlet horizontal plane.

[0063] It can be understood that, such as Figures 1 to 3 、 Figure 5 and Figure 6As shown, on one side of the water inlet end 121 of the main body 1, a water inlet plane is formed, and the same side edges of multiple mounting plates 11 are flush with the water inlet plane. Among them, the cutting edge 221 starts from the mounting plate 11 and extends in a direction away from the mounting plate 11. When the cutting edge 221 extends, it forms an angle with the plane direction of the mounting plate 11. Moreover, the cutting edge 221 can be set flush with the water inlet plane or at an angle with the water inlet plane. In this way, when multiple flow guiding plates 2 are placed in the flocculation chamber 12, the angle of the inclined cutting edge 221 can be adjusted to avoid the cutting edges 221 of adjacent flow guiding plates 2, so as to increase the number of flow guiding plates 2 placed in the flocculation chamber 12, thereby improving the degree of cutting and subdivision of the sewage flow. At the same time, the inclined cutting edge 221 also cooperates with the flow guiding arc edge 222 and the connecting side edge 21, so that the plane of the flow guiding plate 2 forms a curved surface with undulating changes, increasing the turbulence of the sewage flow when flowing in the flow guiding channel 2a, so as to promote the mixing of the medicament and the sewage.

[0064] In one embodiment, the flow guiding side edge 22 further includes a flow guiding tail edge 223. The flow guiding tail edge 223 is connected to one end of the flow guiding arc edge 222 away from the cutting edge 221. The flow guiding tail edge 223 is arranged at the water outlet end 122. The flow guiding plate 2 is arranged as a flat surface or an arc surface from the cutting edge 221 to the flow guiding tail edge 223.

[0065] It can be understood that, as Figures 1 to 3 shown, the flow guiding tail edge 223 is arranged at one end of the flow guiding plate 2 away from the cutting edge 221, that is, the flow guiding tail edge 223 is located at the water outlet end 122 of the flocculation chamber 12. In one embodiment, one end of the flow guiding tail edge 223 is connected to the second side edge 212, and the other end of the flow guiding tail edge 223 is connected to the flow guiding arc edge 222. By setting the flow guiding tail edge 223 and adjusting the angle between the flow guiding tail edge 223 and the mounting plate 11 and / or the central axis of the flocculation chamber 12, the curvature change of the plane of the flow guiding plate 2 is adjusted, so as to realize the adjustment of the flow direction of the sewage flow flowing out of the flow guiding channel 2a, such as flowing out in the vertically downward direction or swirling out along the central axis of the flocculation chamber 12, etc., so as to flexibly set the flow velocity of the sewage flow in the flow guiding channel 2a and the impact collision angle when flowing out of the flow guiding channel 2a, and improve the mixing effect.

[0066] In one embodiment, the flocculation structure 100 includes four mounting plates 11. The four mounting plates 11 are connected end to end in sequence to enclose a flocculation chamber 12 with a square cross-section; the flocculation structure 100 includes four or six or eight flow guiding plates 2.

[0067] It can be understood that, as Figures 1 to 6As shown, the flocculation structure 100 includes four mounting plates 11. The four mounting plates 11 enclose to form the main body 1 of a square frame, such that the cross-section of the flocculation chamber 12 in the up-and-down through direction is square. With such a setting, it is also convenient to connect multiple flocculation structures 100 through the mounting plates 11 to achieve seamless and tight connection, avoid the generation of flow dead corners, improve the cleaning ability and self-cleaning ability, avoid blockage, and at the same time, the connection strength of multiple flocculation structures 100 can be improved through the surface connection of the mounting plates 11, as well as the anti-torsion and anti-impact strengths, further improving the overload capacity of the overall flocculation structure 100.

[0068] Furthermore, four, six or eight flow guiding plates 2 can be arranged in the flocculation chamber 12. The extending directions of the surfaces of the multiple flow guiding plates 2 are arranged at an angle to each other, and with the center of the flocculation chamber 12 as the axis, the inclination angles of the multiple flow guiding plates 2 gradually change, so that the flow guiding channels 2a formed by two adjacent flow guiding plates 2 are spirally distributed. Of course, according to the actual sewage flocculation requirements, as well as different situations such as sewage flow rate and chemical agent addition amount, the flow guiding plates 2 can also be arranged in three, nine or even more than ten, which is not limited herein.

[0069] The utility model also proposes a flocculation device 300, as Figure 7 shown. The flocculation device 300 includes multiple flocculation structures 100 as described above. The multiple flocculation structures 100 are arranged in an array in the horizontal and vertical directions, and two adjacent flocculation structures 100 are connected to each other. Among them, the flocculation chambers 12 of the multiple flocculation structures 100 in the vertical direction are interconnected. The specific structure of the flocculation structure 100 refers to the foregoing embodiments. Since this electronic system adopts all the technical solutions of the foregoing embodiments, it therefore has at least all the beneficial effects brought by the technical solutions of the foregoing embodiments, which will not be elaborated herein one by one.

[0070] It can be understood that multiple flocculation structures 100 are arranged in an array on a horizontal plane, that is, multiple flocculation structures 100 extend and are arranged in two directions that form an angle with each other along the horizontal plane to form a single-layer flocculation layer structure. The flocculation layer structure is realized by the mutual connection of the mounting plates 11 in multiple flocculation structures 100. For example, two adjacent flocculation structures 100 are fixedly connected by welding, screwing, etc., or can be movably connected by clamping, plugging, etc., or share the same mounting plate 11. At the same time, the number of mounting plates 11 in each flocculation structure 100 can be 4, 6, or 8 to enable multiple flocculation structures 100 to achieve seamless and tight connection through the mounting plates 11. Taking the number of mounting plates 11 being 4 as an example, the cross-section of the main body 1 of the flocculation structure 100 is square, and multiple flocculation structures 100 extend and are arranged in two mutually perpendicular directions along the horizontal plane; with such a setting, it can be ensured that both sewage and medicament can flow through the flocculation chamber 12, avoiding the accumulation of sludge and debris and the uneven mixing of sewage and medicament caused by dead corners existing at the connection parts of traditional flocculation structures 100, making the flocculation device 300 not easily blocked and effectively improving the self-cleaning ability of the flocculation device 300.

[0071] Furthermore, the single-layer flocculation layer structures are mutually connected through the mounting plates 11 in the vertical direction to form a multi-layer flocculation layer structure and combine to form the flocculation device 300. Moreover, the flocculation chambers 12 of the upper and lower multi-layer flocculation layer structures are connected and communicated in the vertical direction, so that the flocculation device 300 forms multiple independent and penetrating flocculation channels. In these flocculation channels, the diversion channels 2a in each layer of the flocculation layer structure can be connected end to end in sequence to achieve continuous communication, so as to form a continuous spiral channel from the water inlet top end to the water outlet bottom end of the flocculation device 300, or for the diversion channels 2a in each layer of the flocculation layer structure, the cutting edge 221 on the lower diversion plate 2 can be located in the middle of the water outlet of the upper diversion channel 2a to cut the sewage flowing out of the upper diversion channel 2a, so as to improve the degree of sewage subdivision and the turbulence of the sewage, thereby improving the mixing degree of the sewage and the medicament.

All equivalent structural transformations made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
