[0026] The flocculation reaction tank technologies currently used internationally mainly include mixed flocculation reaction tanks, baffle flocculation reaction tanks, or grid flocculation reaction tanks. The disadvantage is that the chemical solution and the source water flow in the same direction, resulting in serious laminar flow, uneven mixing, and poor flocculation effect.

[0027] The present invention provides a spiral tube 100, which aims to improve the mixing effect between the chemical solution and the sewage, thereby improving the flocculation effect.

[0028] See also Figures 1 to 3In one embodiment of the present invention, the spiral tube 100 includes a plurality of sub-spiral tubes 10 connected in sequence along the vertical direction. Each sub-spiral tube 10 includes a tube body 11 and a plurality of spiral dividing pieces 12. The tube body 11 has a accommodating cavity with openings at both ends. The plurality of spiral dividing pieces 12 extend spirally along the length direction of the tube body 11 and are arranged on the cavity wall of the accommodating cavity for dividing the water flow. The plurality of spiral dividing pieces 12 of two adjacent sub-spiral tubes 10 are staggered.

[0029] In this embodiment, the tube body 11 and the spiral dividing piece 12 of the sub-spiral tube 10 can both be made of metal, such as stainless steel or alloy material, which is not easy to rust, strong and durable, and has strong resistance to water impact. The tube body 11 adopts a hollow cylindrical tubular structure with openings at both ends. The spiral dividing piece 12 is arranged along the length direction of the tube body 11 and is spirally arranged on the wall of the cavity of the accommodating cavity. The medicine and sewage water flows can flow in from the opening at one end of the tube body 11. After being divided by the spiral dividing piece 12, there are simultaneous wave flow, vortex flow and cutting flow between the medicine and sewage water flows, making the mixing more uniform, and then flowing out from the opening at the other end. Using the spiral tube 100 with a spiral dividing piece 12 inside, as long as the water flows along the length direction of the tube body 11, a vortex flow can be realized in the water flow, without the need for an additional stirring pump, thus saving energy. The spiral tube 100 is connected end to end by welding or other connection methods to form an integrated spiral tube 100. Compared with a long spiral tube 100, it can be produced separately in sections, which greatly reduces the difficulty of production. It can be produced using a mold or by welding, which is not further limited here. The spiral dividing pieces 12 between two adjacent sub-spiral tubes 10 are staggered so that the water flowing out of the previous sub-spiral tube 10 flows into the next sub-spiral tube 10 and is cut again by the spiral dividing pieces 12 in the next sub-spiral tube 10, thereby improving the mixing degree between the medicine and the sewage, and ultimately improving the flocculation effect.

[0030] The technical solution of the present invention is to form an integral spiral tube 100 by connecting multiple sub-spiral tubes 10 in sequence in the vertical direction. The tube body 11 of each sub-spiral tube 10 has a receiving cavity with openings at both ends. The cavity wall of the receiving cavity is provided with multiple spiral dividing pieces 12. The medicine and sewage flow into one end of a sub-spiral tube 10 and then flow out from the other end into another sub-spiral tube 10. The medicine and sewage water flow will be divided by the multiple spiral dividing pieces 12 and can form a vortex flow along the spiral dividing pieces 12, thereby improving the mixing degree between the medicine and sewage, and ultimately improving the flocculation effect. The spiral dividing pieces 12 between the two adjacent sub-spiral tubes 10 are staggered, so that the water flow out of the previous sub-spiral tube 10 flows into the next sub-spiral tube 10 and is cut again, thereby improving the mixing degree between the medicine and sewage, and ultimately improving the flocculation effect.

[0031] In the embodiment of the present invention, one end of a spiral dividing piece 12 of a sub-helical tube 10 is located at the midpoint between two adjacent spiral dividing pieces 12 of an adjacent sub-helical tube 10 .

[0032] In this embodiment, the spiral dividing pieces 12 of two adjacent sub-spiral tubes 10 are staggered, and one end of a spiral dividing piece 12 in a sub-spiral tube 10 is located at the midpoint of the two spiral dividing pieces 12 of the adjacent sub-spiral tubes 10, which can further and evenly divide the water flow out of the previous sub-spiral tube 10, thereby improving the mixing degree between the medicine and sewage, and ultimately improving the flocculation effect.

[0033] In an embodiment of the present invention, the plurality of spiral dividing pieces 12 are evenly distributed along the circumferential direction of the cavity wall of the accommodating cavity.

[0034] In this embodiment, multiple spiral dividers 12 are disposed within the tube body 11, dividing the water flow into multiple channels, enhancing the cutting effect on the water flow, thereby improving the mixing effect between the solution and the wastewater, and ultimately improving the flocculation effect. The multiple spiral dividers 12 are evenly spaced around the circumference of the tube body 11, dividing the water flow into multiple evenly spaced channels, enhancing the cutting effect on the water flow, thereby improving the mixing effect of the water flow and improving the flocculation effect.

[0035] In the embodiment of the present invention, the width of the spiral dividing piece 12 is between one fifteenth and one tenth of the diameter of the tube body 11 .

[0036] The width of the spiral dividing piece 12 should not be too wide, otherwise it will reduce the water flux of the spiral tube 100 and reduce the efficiency of sewage treatment. The width of the spiral dividing piece 12 should not be too narrow, otherwise it will prevent the water from flowing along the spiral dividing piece 12, and the generated vortex flow effect will be poor. Therefore, in this embodiment, the width of the spiral dividing piece 12 is between one-fifteenth and one-tenth of the diameter of the tube body 11, for example, one-fifteenth, one-fourteenth, one-thirteenth, one-twelfth, one-eleventh, one-tenth, or any value within the above range. For example, if the diameter of the tube body 11 is 15 cm, the length of the spiral dividing piece 12 can be 1 cm, 1.1 cm, 1.2 cm, 1.3 cm, 1.4 cm, 1.5 cm, or any value within the above range.

[0037] The thickness of the spiral dividing piece 12 is 3mm, 4mm, 5mm or any value within the above range. The thickness of the spiral dividing piece 12 should not be too thin, otherwise it will lead to insufficient strength of the spiral dividing piece 12, and it will be easily distorted or broken by the water flow, causing the cutting or swirl effect of the spiral tube 100 to fail.

[0038] The present invention further provides a spiral tube matrix 200 , comprising a plurality of spiral tubes 100 as described above. The spiral tubes 100 are arranged in a matrix on a horizontal plane, and each spiral tube 100 is connected to adjacent spiral tubes 100 .

[0039] In this embodiment, the spiral tube matrix 200 includes several spiral tubes 100 arranged in a matrix, and the several spiral tubes 100 are distributed on the same horizontal plane. The spiral tube matrix 200 is arranged perpendicular to the flow direction of the water flow. The water flow flows in from the pipe mouths of the several spiral tubes 100 and is divided into several sub-water flows. Then, the water flow is further cut by the multiple spiral dividing pieces 12 staggered in the multiple sub-spiral tubes 10 in the spiral tube 100 to form more and smaller water flows, thereby improving the effect of the divided flow. In addition, the water flow can flow along the spiral dividing pieces 12 to achieve the effect of vortex flow, thereby improving the mixing effect of the medicine and sewage in the water flow, and finally improving the flocculation effect.

[0040] In the embodiment of the present invention, the spiral directions of the spiral segments 12 of the plurality of spiral tubes 100 are arranged in an axisymmetric mirror image with the axis of the spiral tube matrix 200 being the axis.

[0041] In this embodiment, with the central axis of the spiral tube matrix 200 as the axis, the spiral directions of the spiral dividing pieces 12 in the several spiral tubes 100 on one side of the central axis are symmetrically mirrored with the spiral directions of the spiral dividing pieces 12 in the several spiral tubes 100 on the other side. That is, the water flow flowing into the spiral tube matrix 200 rotates in a mirror-symmetrical direction with the central axis of the spiral tube matrix 200 as the axis, realizing vortex flow effects in two different directions, thereby improving the mixing effect of the medicine and sewage in the water flow, and ultimately improving the flocculation effect.

[0042] In the embodiment of the present invention, the outer peripheral walls of the tube bodies 11 of four adjacent spiral tubes 100 enclose a water diversion cavity, and a water diversion member 20 is provided in the water diversion cavity for cutting the water flow into the water diversion cavity.

[0043] In this embodiment, the four spiral tubes 100 enclose a water diversion chamber, and the water diversion member 20 is disposed within the water diversion chamber. This divides the water flow in the dead corners between the four spiral tubes 100 within the spiral tube matrix 200, creating a turbulent flow between the tube bodies 11. This enhances the collision and coagulation between the sewage and the solution, thereby improving the flocculation effect. The water diversion member 20 can also be made of metal, such as stainless steel or an alloy, which is resistant to rust, durable, and highly resistant to water impact.

[0044] In an embodiment of the present invention, the water dividing member 20 includes a plurality of water dividing plates 21 connected at an angle, and the plurality of water dividing plates 21 evenly divide the water dividing cavity into a plurality of parts in the circumferential direction.

[0045] In this embodiment, the water distribution member 2020 includes multiple water distribution plates 2131, which are connected at an angle and evenly divide the second accommodating cavity into multiple parts in the circumferential direction. It can evenly divide the water flow flowing between the multiple spiral tubes 10010 into multiple water flows, forming a cutting flow effect and improving the flocculation effect.

[0046] In one example, one end of the water diversion plate 21 is bent toward the side portion of the water diversion plate 21 to form a bent portion. When the water flow hits the bent portion, a vortex flow will occur, which will form a turbulent state of the water flow flowing into the second accommodating chamber, thereby enhancing the collision and coagulation between the sewage and the medicine, thereby improving the flocculation effect.

[0047] Both ends of the water distribution plate 21 are provided with a bending portion, which can not only cause the water flow flowing into the second accommodating cavity of the spiral tube 100 unit to generate a vortex flow, but also cause the water flow flowing out of the second accommodating cavity of the spiral tube 100 unit to generate a vortex flow, further enhancing the collision and coagulation between the sewage and the medicine, thereby improving the flocculation effect.

[0048] The water distribution element 20 comprises four water distribution plates 21, forming a central four-pointed star-shaped structure. This increases lateral resistance by over 100%, impact resistance by 100%, and overload capacity by 40% to 100%. It also provides seamless cutting and vortex mixing. This facilitates processing, reduces trimming waste, and reduces costs.

[0049] The present invention further provides a spiral tube matrix tower (not shown), comprising a plurality of spiral tube matrices 200 as described above and a frame disposed on the periphery of the spiral tube matrices 200 . The plurality of spiral tube matrices 200 are evenly spaced along the water flow direction.

[0050] In this embodiment, the spiral tube matrix tower comprises a plurality of spiral tube matrices 200 and a frame disposed around the outer periphery of the spiral tube matrices 200. The spiral tube matrices 200 are evenly spaced and arranged perpendicular to the water flow. The multiple spiral tube matrices 200 enhance the uniformity of mixing of the chemical solution and wastewater in the water flow, further improving the flocculation effect. The frame also enhances the spiral tube matrices 200's resistance to water flow shock, increasing their stability and durability.

[0051] The present invention also provides a flocculation reaction tank, comprising the spiral tube matrix tower described above.

[0052] 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 transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
