Description

Technical Field

[0001] This utility model relates to the technical field of supermagnetic separation equipment, and specifically provides a flocculation and coagulation device. Background Technology

[0002] Supermagnetic separation water purification technology is mainly used to remove non-magnetic or weakly magnetic particulate pollutants from water. Its technical principle is based on traditional coagulation technology, by adding a magnetically conductive medium. This magnetic medium inoculates the chemical flocs formed during coagulation with magnetism, and then uses an external magnetic field to separate these flocs from the water. In other words, magnetic separation replaces the sedimentation process in traditional coagulation, thus achieving rapid and efficient water purification. The coagulation and flocculation equipment is an indispensable pretreatment device in supermagnetic separation technology. It can fully and uniformly mix the coagulant (such as polyaluminum chloride, polyaluminum ferric chloride, etc.) with the suspended solids in the water, ensuring that the coagulant is quickly and evenly dispersed throughout the water body.

[0003] Existing flocculation equipment is assembled from flat steel plates. During flocculation, the surface of the flat steel plates is too smooth and flat, which leads to low mixing efficiency of the flocculation equipment. Utility Model Content

[0004] On the one hand, in order to solve the above problems, this utility model provides a flocculation device with better mixing efficiency, and the specific technical solution is as follows:

[0005] A flocculation device includes a side wall and a bottom plate, the side wall and the bottom plate forming a cylinder, the side wall including a corrugated plate, and vertical ridges spaced apart on the corrugated plate.

[0006] In this solution, the traditional flat steel plate is replaced with a corrugated plate with ridges. Due to the presence of ridges, the inner wall of the cylinder is no longer smooth, which prevents the water flow from swirling steadily during mixing. The water flow near the outer side is blocked by the ridges, creating turbulence and making the water flow inside the cylinder more chaotic, thus improving the efficiency and quality of mixing. At the same time, the corrugated plate with ridges serves as the side wall of the flocculation equipment, providing higher strength, making the flocculation equipment more robust, and less prone to the pitting and unevenness that occurs on the surface of flat steel plates.

[0007] On the other hand, in order to further increase the mixing efficiency and avoid dead zones caused by the ridges on the inner wall of the cylinder, the ridges include convex ridges and concave ridges arranged in sequence, and the angle between the convex ridges and concave ridges is an obtuse angle.

[0008] In this scheme, when the flocculant particles and flocs are stirred and rotated, they enter the outwardly concave ridges and will flow out directly with the water flow because the angle is obtuse, without accumulating in the ridges.

[0009] Traditionally, flat steel plates are assembled into flocculation equipment by welding. However, on-site welding often takes a lot of time for workers. Therefore, to facilitate installation, the corrugated plates are provided with bending sections on the left and right ends, and the corrugated plates are detachably connected sequentially through these bending sections. This detachable connection method allows for modular and rapid installation. If a corrugated plate is damaged, it can be quickly removed and replaced, facilitating both rapid installation and subsequent maintenance.

[0010] The number of sidewall plates required varies depending on the specifications of the flocculation tank. To ensure effective mixing, the cylinder is a rectangular parallelepiped. Each sidewall includes a corrugated plate, with the left and right bends of the corrugated plate connected. This design allows workers to quickly assemble the flocculation tank. Preferably, the left and right ends of the corrugated plate are not connected at right-angle bends, but rather on one side of the cylinder for easier connection.

[0011] Alternatively, the cylinder can be a rectangular parallelepiped, with its sidewalls comprising multiple corrugated plates that are detachably connected sequentially via the bending portions. When the flocculation tank is large, a single cylinder requires multiple corrugated plates to form its sidewalls. Since the corrugated plates are detachably connected, if a single plate malfunctions or is damaged, only the corresponding plate needs to be disassembled and repaired; other corrugated plates do not need to be touched, thus improving maintenance convenience.

[0012] Preferably, the outer side walls of the corrugated sheet are welded with horizontal reinforcing bars.

[0013] In this solution, to prevent the corrugated sheet from bending and deforming after installation, reinforcing rods are welded on. These reinforcing rods are perpendicular to the ridge, which increases the strength of the corrugated sheet while also preventing it from bending and deforming.

[0014] Preferably, a connecting part is welded to the lower end of the corrugated plate, and the corrugated plate is detachably connected to the base plate through the connecting part.

[0015] Preferably, the cylinder is a cuboid cylinder, and the upper end of the corrugated plate is provided with a limiting support part, the limiting support part is provided with a strip-shaped limiting groove, and the upper end of the corrugated plate is inserted into the limiting groove.

[0016] In this design, during the installation of the corrugated sheet, the limiting support can maintain the straightness of the corrugated sheet by relying on the strip limiting groove. At the same time, the presence of the ridge on the corrugated sheet can make the limiting support more stable on the side wall of the cylinder, so as to provide a better installation and support effect for other equipment on the top.

[0017] Preferably, the bent portion abuts against the limiting support portion from below, thereby further improving the strength and stability of the limiting support portion.

[0018] Preferably, a stirring beam is supported on the limiting support, and a stirring unit extending into the cylinder is provided on the stirring beam. This direct connection ensures effective mixing while reducing material costs and increasing installation speed.

[0019] Preferably, a walkway beam is provided on the limiting support, and the walkway beam and the limiting support together support the inspection walkway. Since there is no top cover structure, the strength of the installed inspection walkway can be improved by the walkway beam.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model replaces the traditional flat steel plate with a corrugated plate with ridges. Due to the presence of ridges, the inner wall of the cylinder is no longer smooth, so that the water flow will not rotate stably during the mixing of the flocculation equipment. The water flow near the outside is blocked by the ridges and generates turbulence, making the water flow inside the cylinder more turbulent, thus improving the efficiency and quality of mixing.

[0022] 2. This utility model uses corrugated plates with ridges as the side walls of the flocculation equipment, which has higher strength, making the flocculation equipment more reliable and less prone to pitting like on the surface of flat steel plates. Attached Figure Description

[0029] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of this utility model.

[0030] A flocculation device can be strictly divided into a PAM mixing tank, a magnetic media mixing tank, and a PAM mixing tank. Each tank in this invention includes a side wall 1 and a bottom plate 2, such as... Figure 1 As shown, the side wall 1 and the bottom plate 2 form a cylindrical body. The side wall 1 includes a corrugated plate 11, on which vertical ridges 12 are spaced apart.

[0031] Specifically, the cylinder body is preferably a rectangular parallelepiped. The corrugated plates 11, after being disassembled from the rectangular parallelepiped, are easier to transport and install than a cylindrical cylinder. The ridges 12 include sequentially arranged convex ridges 121 and concave ridges 122, with the angle α between the convex ridges 121 and concave ridges 122 being an obtuse angle, preferably 120 degrees. During stirring and rotation, flocculant particles, flocs, and other substances enter the outwardly concave ridges 122 and, due to the obtuse angle, flow directly out with the water flow, preventing accumulation in the ridges 122. This design, based on the improved stirring effect achieved by using corrugated plates 11, further increases mixing efficiency and avoids the formation of dead zones in the ridge structure 12.

[0032] The traditional flat steel plate is replaced with a corrugated plate 11 with ridges 12. Due to the presence of ridges 12, the inner wall of the cylinder is no longer smooth, so that the water flow will not swirl steadily during the mixing of the flocculation equipment. The water flow near the outside is blocked by the ridges 12, which generates turbulence and makes the water flow inside the cylinder more turbulent, thus improving the efficiency and quality of mixing. At the same time, the corrugated plate 11 with ridges 12 serves as the side wall 1 of the flocculation equipment, which has higher strength, making the flocculation equipment more reliable and less prone to the pitting and unevenness that occurs on the surface of the flat steel plate.

[0033] Example 1:

[0034] The specifications of the flocculation tank vary depending on its treatment capacity, and the number of sidewall plates required also varies. When the treatment capacity is less than or equal to 10,000 m³ / d, it is considered a small-capacity flocculation tank. In this case, the flocculation equipment is relatively small, and the sidewall 1 can be formed by bending a single corrugated plate 11 at multiple right angles. The left and right ends of the corrugated plate 11 have bending sections 13, which include folded plates perpendicular to the surface of the corrugated plate 11. These folded plates are typically formed by directly bending both ends of the corrugated plate 11, or they can be formed by external welding. The folded plates have evenly distributed threaded holes. The left and right folded plates are directly connected by bolts, and a sealing agent is applied between the two folded plates. It should be noted that... Figure 2 and Figure 3As shown, the folded plate is preferably arranged at the concave ridge 122 of the corrugated plate 11 and is arranged outward in the groove formed by the concave ridge 122, which can facilitate workers to install and connect the corrugated plate 11 on the outside.

[0035] Since the bent portions 13 at the left end and the right end of the corrugated plate 11 are connected, this setting enables workers to quickly assemble the mixing and flocculation tank. When the cylinder is a cuboid cylinder, there are right angles. Preferably, the left and right ends of the corrugated plate 11 are not connected at the right angles, but are connected on one side of the cylinder, so as to facilitate workers to more conveniently connect the corrugated plate 11 and avoid poor sealing when connecting at the right angles.

[0036] Embodiment 2:

[0037] When the treatment capacity is greater than or equal to 10,000 m3 / d, it is a large treatment capacity. The coagulation equipment is relatively large in volume and requires multiple corrugated plates 11 to be spliced. In this case, traditional flat steel plates are generally welded together to form the mixing and flocculation equipment, and on-site welding often takes a lot of time for workers. Therefore, for the convenience of workers' installation, the side wall 1 is composed of multiple corrugated plates 11 that are detachably connected. And like Embodiment 1, as Figure 2 and Figure 3 shown, the left end and the right end of a single corrugated plate 11 are provided with bent portions 13. The bent portion includes a folded plate perpendicular to the surface of the corrugated plate 11, which is usually obtained by directly bending the two ends of the corrugated plate 11, or can also be formed by an external welding method. The folded plate is uniformly provided with threaded holes, and the folded plates at the left end and the right end are directly connected by bolts, and a sealing agent is filled between the two folded plates. The side wall 1 of the cylinder includes multiple corrugated plates 11, and the corrugated plates 11 are detachably connected by the bolts at the bent portions 13. When a single plate has problems or is damaged, only the corresponding plate needs to be disassembled and repaired, without moving other corrugated plates 11, which improves the convenience of maintenance.

[0038] Furthermore, in this embodiment, like Embodiment 1, when the cylinder is a cuboid cylinder, the connection position between the folded plates of two adjacent corrugated plates 11 is not at the right angle position of the cylinder. The connection of two adjacent corrugated plates 11 occurs on the right-angled side of the side wall 1, which is more conducive to the docking of the folded plates.

[0039] It should be noted that a single corrugated plate 11 can be bent at a right angle, such as an "L"-shaped corrugated plate 11 with one bend or a "冖"-shaped corrugated plate 11 with two bends. In order to facilitate the transportation of the corrugated plate 11, after a single corrugated plate 11 is provided with a right-angle bend, the bent part should not be too long, so as to facilitate controlling the space occupied by the corrugated plate 11. When the width is not enough, it can be directly patched with a corrugated plate 11 without a right-angle bend. As Figure 2As shown, the side wall 1 consists of four corrugated sheets 11. Two of the corrugated sheets 11 have right-angle bends at both ends, and a folding plate is provided at the first concave ridge 122 after the bend. The other two corrugated sheets 11 are flat corrugated sheets 11, with folding plates at both ends. Preferably, the folding plates are located at the concave ridge 122 of the corrugated sheet 11, with the height of the folding plates being the same as the height of the convex ridge 121, and are positioned outwards in the groove formed by the concave ridge 122, facilitating the installation and connection of the corrugated sheets 11 from the outside by workers.

[0040] Furthermore, similar to Embodiment 1, a connecting portion 14 is welded to the lower end of the corrugated plate 11. The connecting portion 14 includes a connecting plate that is adapted to the length of the corrugated plate 11 and parallel to the base plate 2. The connecting plate is perpendicular to the surface of the corrugated plate 11, and the connecting plate and the base plate 2 are provided with corresponding holes. During installation, sealant needs to be applied to the connecting plate, and then the base plate 2 and the connecting portion 14 are connected by bolts to achieve a detachable connection between the corrugated plate 11 and the base plate 2.

[0041] Example 3:

[0042] Based on the above-described embodiments one or two, in order to ensure the strength of the corrugated plate 11 and the entire flocculation equipment, such as Figure 1 As shown, horizontal reinforcing rods 3 are welded to the outer side walls 1 of the corrugated plate 11. In order to prevent the corrugated plate 11 from bending and deforming after installation, the reinforcing rods 3 are welded perpendicular to the ridge 12, which increases the strength of the corrugated plate 11 and also prevents the corrugated plate 11 from bending and deforming.

[0043] Furthermore, the cylindrical body is preferably a rectangular parallelepiped, such as... Figure 1 As shown, a limiting support part 15 is provided at the upper end of the corrugated plate 11. The limiting support part 15 has a strip-shaped limiting groove. The upper end of the corrugated plate 11 is inserted into the limiting groove. The limiting support part 15 can be made directly from channel steel or a customized component. It is preferred to use channel steel directly, and the width of the channel steel needs to be greater than the thickness of the corrugated plate 11 so that the corrugated plate 11 with the ridge 12 can also be inserted into the strip-shaped limiting groove. When the corrugated plate 11 is installed, the limiting support part 15 can maintain the straightness of the corrugated plate 11 by relying on the strip-shaped limiting groove. At the same time, the presence of the ridge 12 on the corrugated plate 11 also makes the limiting support part 15 more stable on the side wall 1 of the cylinder, so as to provide a better installation and support effect for other equipment on the top.

[0044] Of course, the bent portion 13 abuts against the limiting support portion 15 from below, so that the bent portion 13 also supports the limiting support portion 15, further improving the strength and stability of the limiting support portion 15.

[0045] Example 4:

[0046] Based on Example 3, since existing flocculation equipment is generally installed directly inside the container, there is no need to install a top cover to prevent debris from entering. Figure 1 As shown, a stirring beam 4 is supported on the limiting support part 15. A stirring unit 5 extending into the cylinder is provided on the stirring beam 4. To ensure effective mixing, the stirring unit 5 is supported by the stirring beam 4 instead of the top cover, reducing material costs and increasing installation speed. Furthermore, a walkway beam is provided on the limiting support part 15, which, together with the limiting support part 15, supports an inspection walkway. The walkway beam enhances the strength of the installed inspection walkway. Both the stirring beam 4 and the walkway beam can have holes at both ends for bolt connection to the limiting support part 15, or they can be directly welded.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
