Description

Technical Field

[0001] The invention belongs to the technical field of water purification equipment and relates to a spiral micro-vortex flocculator. Background Art

[0002] Flocculation is a very important process step in water treatment, which is used to remove suspended and colloidal impurities in water. The implementation of flocculation process requires chemical conditions and hydraulic conditions: the chemical condition is to add flocculants to the water to make the impurities in the water lose their suspension stability, while the hydraulic condition is to form a suitable flow velocity distribution by constraining the water flow to promote the collision, coagulation and adsorption flocculation of impurity particles in the water.

[0003] For example, people have designed a high-efficiency micro-vortex flocculation ball and applied for a Chinese patent, with the application number: 201320417860.6; the announcement number: 203419778U. The flocculation ball is a hollow sphere made of ABS material, with a thickness of 2 to 3 mm and a size of 120 to 260 mm; the sphere is evenly distributed with 12 to 36 mm round holes. When water flows through a large number of holes on the wall of the high-efficiency micro-vortex flocculation ball, countless tiny vortices are formed, which are conducive to the migration and collision coagulation of fine particles in the water, thereby improving the reaction efficiency.

[0004] However, in actual use, the flocculation balls are spherical in shape, and it is difficult to effectively fix them when placed in a flocculator, resulting in uncontrollable distribution direction of holes on the flocculation balls and water flow direction, which in turn leads to uncontrollable flocculation effect. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and propose a spiral micro-vortex flocculator to solve the problem that the flocculation effect of the existing flocculation balls is uncontrollable.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A spiral micro-vortex flocculator is characterized in that the flocculator comprises a cone-shaped cylinder with both ends of the cylinder open, the inner wall of the cylinder has a plurality of protruding plate-shaped guide plates, several of the guide plates are distributed around the axis of the cylinder, the extension direction of the several guide plates from one end close to the larger diameter of the cylinder to the other end is inclined relative to the axis of the cylinder, and the several guide plates are inclined in the same circumferential direction.

[0008] The cylinder of the spiral micro-vortex flocculator is in the shape of a cone, and its end can be stably placed in the grid of the flocculator. When the water flows through, it is affected by the gradually shrinking inner wall of the cylinder, and the water flow is converged and accelerated to collide. At the same time, because the inclination direction of the guide plate in the cylinder is consistent, the water flow will rotate clockwise or counterclockwise under its guidance, forming a tiny vortex, promoting the collision and coagulation of impurity particles in the water and adsorption flocculation, achieving a better effect of promoting flocculation. During this use process, the end of the spiral micro-vortex flocculator can be stably placed, the placement direction is stable, and the water flowing along the axial direction will not cause the entire cylinder to flip, so that the flow direction and flocculation effect of the water flow are controllable, and the flocculation stability is good.

[0009] In the above-mentioned spiral micro-vortex flocculator, there is a spacing between the ends of the guide plates away from the inner wall of the cylinder, and a water passage for water flow is formed at the axis of the cylinder. The guide plates are spaced apart and do not abut against each other to separate the cylinder into several separate passages, so that the water flows passing through the cylinder are always connected, and the rotating water flow at the periphery drives the water flow at the center to rotate to accelerate the collision of impurities, so that the impurities in the water flow can be connected with each other, and a better flocculation effect is achieved.

[0010] In the above spiral micro-vortex flocculator, the ends of several guide plates away from the inner wall of the cylinder are all provided with concave clearance openings, and the bottom surfaces of the clearance openings of several guide plates are all located on the same cylindrical surface. The vortices are all circular, so the bottom surfaces of the clearance openings set at the ends of the guide plates are located on the same cylindrical surface, making it easier for the vortex to form and the impurities in the water to collide more frequently.

[0011] In the above-mentioned spiral micro-vortex flocculator, the bottom surface of the clearance opening is in an arc shape.

[0012] In the above spiral micro-vortex flocculator, connecting holes are formed on both opposite sides of the cylinder. When the cylinder is placed in the flocculator, since the center of the cylinder is not separated by the guide plate, the cylinder can be fixed in the flocculator by passing the iron wire through the connecting hole, the water passage and the connecting hole on the other side in sequence, so that the placement of the cylinder is more stable and the flocculation effect is more stable.

[0013] In the above spiral micro-vortex flocculator, the number of the connection holes is at least four. The four connection holes can be used for two iron wires to cross and fix, so that the connection is more stable and it is convenient to arrange several cylinders in a square or diamond shape and then connect and fix them in sequence.

[0014] In the above spiral micro-vortex flocculator, both end faces of the cylinder are planes, which not only makes the cylinder more stable, but also ensures that the water flow does not disperse at the outlet after forming a vortex.

[0015] In the above-mentioned spiral micro-vortex flocculator, a plurality of guide plates are distributed on the inner wall of the cylinder at equal intervals.

[0016] Compared with the prior art, the spiral micro-vortex flocculator can place a plurality of cylinders stably and orderly on the grid of the flocculator by means of the arrangement of the conical cylinder and the connecting holes. The placement is stable and the flocculation effect is controllable and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1 to Figure 4 As shown, the spiral micro-vortex flocculator includes a cone-shaped cylinder 1 with both ends of the cylinder 1 open, and the end faces of both ends of the cylinder 1 are flat. The inner wall of the cylinder 1 has a plurality of protruding plate-shaped guide plates 2, and the guide plates 2 are evenly spaced around the axis of the cylinder 1. The extension direction from one end of the cylinder 1 with a larger diameter to the other end of the guide plates 2 is inclined relative to the axis of the cylinder 1, and the guide plates 2 are inclined in the same circumferential direction. In this embodiment, the inclination angle of the guide plate 2 can be 10 to 30 degrees, and the specific inclination angle can be adjusted according to the vortex generation during the installation test.

[0025] The ends of the guide plates 2 away from the inner wall of the cylinder 1 are all provided with arc-shaped recessed openings 4, and the bottom surfaces of the openings 4 of the guide plates 2 are all located on the same cylindrical surface. In this embodiment, the radial width occupied by the guide plates 2 is greater than the radial width of the water passage 3 when viewed from the ends with larger and smaller diameters of the cylinder 1.

[0026] The cylinder 1 has two opposite sides through which connection holes 5 are formed, and the number of the connection holes 5 is at least four. In this embodiment, the number of the connection holes 5 is four, and they are formed on the side wall of the cylinder 1 in a cross-shaped manner.

[0027] like Figure 5 As shown, the cylinder 1 of the spiral micro-vortex flocculator is in a cone shape, and several cylinders 1 can be placed vertically on a grid, and several cylinders 1 are equidistantly distributed in a square shape, and adjacent cylinders 1 are set in reverse, that is, the end with a smaller diameter on one cylinder 1 of the adjacent cylinders 1 faces upward, and the end with a larger diameter on the other cylinder 1 faces upward, and the connecting holes 5 of the adjacent cylinders 1 are relatively positioned, and the cylinders 1 are strung together by cross-arranged iron wires that pass through the connecting holes 5 on each cylinder 1 in turn, and the two ends of the iron wires are fixed to ensure the stability of the placement of the cylinders 1, forming a whole layer of flocculators with M rows and N columns. The specific number of rows and columns can be determined according to the size of the actual installation space to form the best flocculation micro-vortex effect, wherein the iron wire can be bent and arranged around the guide plate 2 where it is blocked by the guide plate 2.

[0028] When the water flows through, it is affected by the gradually shrinking inner wall of the cylinder 1, and the water flow is converged and accelerated. At the same time, because the inclination direction of the guide plate 2 in the cylinder 1 is consistent, the water flow is guided to rotate in a clockwise or counterclockwise direction to form a tiny vortex, which promotes the collision, coagulation and adsorption flocculation of impurity particles in the water, achieving a better effect of promoting flocculation.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
