Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a disk, a disk assembly and a high-intensity magnetic separation device. Background Art

[0002] Magnetic separation utilizes the magnetism of impurity particles in wastewater for separation. For non-magnetic or weakly magnetic particles in water, magnetic seeding technology can endow them with magnetism, and with the action of an external magnetic field, the magnetic suspended solids (magnetic flocs) in the wastewater can be separated, so as to achieve the purpose of purifying water.

[0003] A high-intensity magnetic separation device (or called a magnetic separation device, a magnetic separator, a high-intensity magnetic separator) is a wastewater treatment device made based on the magnetic separation principle and is widely used in the field of wastewater treatment. As the core component of the high-intensity magnetic separation device, the disk is directly related to the treatment effect of wastewater. Some disks have water passing holes in the middle, and the sewage enters from the outside and exits from the inside, improving the utilization rate of the disk and improving the slag dropping phenomenon.

[0004] In the patent document with the publication number, the disk is sleeved on the disk shaft, the distance between adjacent disks is determined by a spacer sleeve sleeved on the disk shaft, and the perpendicularity between the disk and the disk shaft (or the adjustment of the disk plane error) is adjusted by components such as a full-thread screw rod, a positioning sleeve, a spring washer and a nut. The structure of the above disk is single, and more accessories are required for positioning and shaping during the assembly process, resulting in a more cumbersome assembly of the device, which needs to be improved.

[0044] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0045] Embodiment 1

[0046] Refer to Figures 1 to 5 , this embodiment provides a high-gradient magnetic separation device, including a disk 1 assembly. The disk 1 assembly includes a disk 1, a connecting member 2, and a limiting member 3.

[0047] The middle part of the disk 1 has a water passing hole 11 in a circular shape or the like; a bracket 12 is connected inside the water passing hole 11; a plurality of positioning columns 13 are distributed on both opposite sides of the bracket 12. The axis of the positioning column 13 is parallel to the axis of the disk 1, and the positioning columns 13 on both opposite sides of the bracket 12 are coaxially arranged in pairs; a connecting hole 14 is formed in the positioning column 13 along its own axial direction; one end of the positioning column 13 protrudes from the side surface of the disk 1.

[0048] The bracket 12 includes a central part 15 and support rods 16. A plurality of support rods 16 are distributed around the outside of the central part 15, and the support rods 16 are used to connect the inner wall of the water passing hole 11 and the central part 15.

[0049] The connecting member 2 can penetrate through the connecting hole 14 to connect a plurality of disks 1 in series.

[0050] Limiting members 3 such as fastening nuts are arranged at both ends of the connecting member 2 for fastening a plurality of disks 1 together.

[0051] During assembly, the positioning column 13 on the disk 1 is first sleeved on the connector 2, and then the multiple disks 1 are fastened together by the limiting members 3 such as the fastening nut, which is simple and convenient to assemble. Since the axis of the positioning column 13 is parallel to the axis of the disk 1, the positioning columns 13 located on the opposite sides of the bracket 12 are coaxially arranged in pairs, and one end of the positioning column 13 protrudes from the side of the disk 1. Therefore, in the process of fastening the multiple disks 1 together by the limiting members 3 such as the fastening nut, on the one hand, the distance between adjacent disks 1 is conveniently determined by the abutment contact between the two positioning columns 13, and on the other hand, the squeezing between the positioning columns 13 plays a role in making the adjacent disks 1 parallel to each other, improving the flatness error of the disk 1, and having a correction effect on the disk 1; the closer the positioning column 13 is to the edge of the disk 1, the better the correction effect of the disk 1. The connector 2 can be installed on other transmission components so as to drive the disk 1 to rotate through the connector 2. In addition, since there is a water hole 11 in the middle of the disk 1, sewage can also enter from the outside and exit from the inside to achieve the corresponding effect.

[0052] As can be seen from the above, in this embodiment, the connecting member 2 not only plays the role of connecting multiple disks 1 in series, but also can be connected to other transmission devices to drive the disks 1 to rotate.

[0053] Example 2

[0054] See also Figures 1 to 5 The present embodiment is different from the first embodiment in that the disk 1 assembly further includes a rotating shaft (not shown in the figure), and the bracket 12 includes a central portion 15 and a support rod 16 .

[0055] The center portion 15 is annular, and the positioning column 13 is located on the support rod 16. The center portion 15 can be sleeved on the rotating shaft, and the rotating shaft can drive the center portion 15 and the disk 1 to rotate. In this embodiment, preferably, a key slot 17 is provided on the inner side of the center portion 15, and the center portion 15 is key-connected with the rotating shaft to realize transmission between the two. In other embodiments, the center portion 15 can also be connected to the rotating shaft in other ways.

[0056] In this embodiment, the rotation of the magnetic disk 1 can be driven by a rotating shaft.

[0057] Example 3

[0058] See also Figure 4 The difference between this embodiment and Embodiment 2 is that the central portion 15 is in the shape of a circular plate, and the positioning column 13 is located on the central portion 15 or the support rod 16 . Preferably, the positioning column 13 is located on the central portion 15 .

[0059] In this embodiment, the connecting member 2 not only serves to connect multiple disks 1 in series, but can also be connected to other transmission devices to drive the disks 1 to rotate.

[0060] Example 4

[0061] See Figure 5 , the difference between this embodiment and Embodiment 3 is that the central part 15 is in the shape of a square plate, and the positioning column 13 is located on the central part 15 or the support rod 16. Preferably, the positioning column 13 is located on the support rod 16.

[0062] In this embodiment, the connector 2 not only serves to connect multiple disks 1 in series, but also can be connected to other transmission devices to drive the disks 1 to rotate.

[0063] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Without conflict, the embodiments of this application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
