Description

Technical Field

[0001] This utility model belongs to the technical field of mineral processing equipment and relates to a medium box installation and positioning device for a vertical ring mill. Background Technology

[0002] High-gradient vertical ring magnetic separators are commonly used equipment for separating weakly magnetic minerals. Their working principle involves placing magnetic media such as steel rods and steel mesh within a uniform magnetic field generated by an iron-clad solenoid. This magnetization creates a highly non-uniform magnetic field on the radial surface, resulting in a high-gradient magnetization magnetic field. During mineral processing, the rotating ring rotates clockwise. The slurry is fed into the feed hopper and flows through the upper yoke gaps into the rotating ring. The magnetic media box inside the rotating ring is magnetized in the magnetic field, forming a high-gradient magnetic field on its surface. Magnetic particles in the slurry are attracted to the magnetic media surface and carried to the top non-magnetic area as the ring rotates. These particles are then flushed into the magnetic product hopper by washing water, while non-magnetic particles flow into the non-magnetic product hopper through the lower yoke gaps and are discharged.

[0003] The generation and strength of the magnetic field in a high-gradient vertical ring mill are closely related to parameters such as the material, shape, size, and filling rate of the magnetic media box. When the magnetic media box operates in slurry for extended periods, the following problems are likely to occur: ① Cracks in the media box nut due to ore inclusions and loosening of bolts cause fluctuations in the vertical ring mill's turntable current; ② If the nut or bolt falls off during turntable operation, it can cause turntable jamming, resulting in significant labor and cost expenditures and severely restricting production. Currently, the welding method for the media box nut on-site involves arbitrarily welding at the original weld point of the fallen nut, resulting in an uneven nut and inaccurate positioning. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing a vertical ring machine media box installation and positioning device, which solves the problem that the current on-site welding method for media box nuts is to arbitrarily weld at the original welding point of the detached nut, resulting in the nut not being flat and unable to be effectively and accurately positioned.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] A media box mounting and positioning device for a vertical ring machine includes several mounting plates arranged symmetrically. The mounting plates are square, with protrusions at their four corners and a first mounting hole and a second mounting hole in the center. The angle between the protrusions and the mounting plates is 3 to 10 degrees. The protrusions are square, and two insertion holes are arranged side by side in the center. The first mounting hole is rectangular with arc-shaped corners, and the second mounting hole is rectangular with arc-shaped corners.

[0007] Furthermore, the first mounting hole and the second mounting hole are arranged side by side, and both have the same width.

[0008] Furthermore, the center points of the first mounting hole and the second mounting hole are located on the same straight line, and there is a gap of 30~50mm between them.

[0009] Furthermore, the diameter of the socket is 20~30mm.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention can accurately position the welding of loose nuts on the medium of the vertical ring machine, improve the bolt preload, reach the bolt torque standard, eliminate the phenomenon of turntable jamming caused by the detachment of nuts and bolts, improve the process performance and technical indicators of the medium box, and realize the simultaneous welding and installation of nuts of multiple medium boxes, which greatly improves the installation efficiency. In addition, this invention also has the advantages of simple manufacturing and installation process, convenient maintenance, and lightweight and practicality. Attached Figure Description

[0016] Example 1

[0017] like Figure 1 As shown, a medium box installation and positioning device for a vertical ring machine includes two symmetrically arranged mounting plates 1. The mounting plates 1 are square, with protrusions 2 at the four corners and a first mounting hole 3 and a second mounting hole 4 in the middle.

[0018] like Figure 2 As shown, the angle between the protrusion 2 and the mounting plate 1 is 4.5 degrees; the protrusion 2 is square, and there are two parallel insertion holes 5 in the middle, with a diameter of 20mm.

[0019] The first mounting hole 3 and the second mounting hole 4 are arranged side by side, both with a width of 118.8 mm. The center points of the first mounting hole 3 and the second mounting hole 4 are located on the same straight line, and there is a 30 mm gap between them. Specifically, the first mounting hole 3 is a rectangle with a length of 95.5 mm and its four corners are arc-shaped; the second mounting hole 4 is a rectangle with a length of 114.5 mm and its four corners are arc-shaped.

[0020] This embodiment is mainly used for centralized welding of the rotating ring nuts of the SLon2500 vertical ring machine. It can weld 6 medium box nuts at one time. First, the original nuts need to be cut off and ground flat. Then, 16 medium box bolts and nuts are tightened into the insertion hole 5. Next, the first mounting hole 3 and the second mounting hole 4 are placed at the welding position of the turntable to weld the 6 medium box nuts. After welding, the 16 bolts and nuts are removed. Finally, the medium box is installed.
