Description
TECHNICAL FIELD
[0001] The utility model belongs to superconducting magnetic separation equipment technical field, specifically a superconducting medium module lifting structure of superconducting magnetic separation equipment. BACKGROUND
[0002] At present, superconducting magnetic separation equipment is needed to complete accurate and meticulous separation in the process of concentrate purification. Figure 1 And Figure 2 As shown in the drawings, the superconducting magnetic separation equipment generally has a superconducting magnet module 001, a yoke plate module 002 and a superconducting medium module 003. The superconducting medium module 003 is located inside the superconducting magnet module 001, and generally has medium boxes required for different materials arranged in the height direction inside the superconducting medium module 003. The superconducting medium module 003 is designed in cooperation with the superconducting magnet module 001 to generate a very high gradient field to separate and purify materials in different states. The yoke plate module 002 is located outside the superconducting magnet module 001 to provide a magnetic field shielding effect to prevent the magnetic field from diverging and affecting the operation of external equipment.
[0003] The current superconducting magnetic separation equipment only has the function of single material separation and does not have dry separation and wet separation processes at different times. If the magnetic separation process and the material to be separated are replaced, the overall equipment needs to be changed greatly, which takes a long time and costs a lot.
[0004] In one of the improved ways, a lifting cylinder 004 is simply installed on the frame body of the yoke plate module 002 by a lifting cylinder mounting frame 006, and a connecting platform 005 connected with the superconducting medium module 003 is driven by the lifting cylinder 004, so that the superconducting medium module 003 is lifted inside the superconducting magnet module 001 to adapt to different process requirements such as dry separation and wet separation. By lifting the connecting platform 005, the medium boxes required for different materials and magnetic separation processes are located in the superconducting magnetic field area, and the magnetic separation function of multiple materials and processes can be realized by the same set of equipment.
[0005] The structure of the lifting cylinder 004 simply driving the connecting platform 005 makes the connecting platform 005 generally have only one highest position and one lowest position for stopping, and cannot make the connecting platform 005 stop and fix at multiple height positions. When the air supply of the lifting cylinder 004 is disconnected accidentally, the connecting platform 005 and the superconducting medium module 003 are also likely to fall suddenly, causing damage to the equipment.

[0031] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail.
[0032] A lifting structure for a superconducting dielectric module in a superconducting magnetic separation device, such as Figures 1-7 As shown, this embodiment includes a lifting cylinder 004, a lifting cylinder mounting bracket 006, and a connecting platform 005. The cylinder body of the lifting cylinder 004 is mounted on the frame of the yoke module 002 of the superconducting magnetic separator via the lifting cylinder mounting bracket 006. In this embodiment, the lifting cylinder 004 is a commercially available product, and its operation is controlled by an external controller. The installation and connection method between the lifting cylinder 004, the lifting cylinder mounting bracket 006, and the frame of the yoke module 002 of the superconducting magnetic separator adopts existing technology.
[0033] The superconducting medium module lifting structure of the superconducting magnetic separation device in the embodiment further comprises a positioning cylinder mounting bracket 1, a positioning cylinder 2, a positioning block 3, and a guide shaft 4. The driving end of the lifting cylinder 004 is vertically upward and connected with a connecting platform 005. The connecting platform 005 is connected with the upper portions of two guide shafts 4. The two guide shafts 4 are symmetrically arranged on the left and right sides of the lifting cylinder 004. The axial center lines of each guide shaft 4 are perpendicular to the horizontal plane. A plurality of annular limiting clamping grooves 401 are formed on each guide shaft 4 in the axial direction. The height positions of the annular limiting clamping grooves 401 on each guide shaft 4 correspond to the height positions of the annular limiting clamping grooves 401 on the other guide shafts 4 one by one. The widths of all the annular limiting clamping grooves 401 in the up-down direction are equal. The specific number and height position of each annular limiting clamping groove 401 can be adjusted as required.
[0034] A positioning cylinder mounting bracket 1 is mounted at the corresponding position of each guide shaft 4 on the lifting cylinder mounting bracket 006. A cylinder body of a positioning cylinder 2 is arranged on each positioning cylinder mounting bracket 1.

The guide shaft passing hole 301 on each positioning block 3 is divided into a small aperture portion 3011 and a large aperture portion 3012. Each guide shaft 4 passes through the corresponding positioning block 3 and the positioning cylinder mounting bracket 1. The aperture size of the large aperture portion 3012 of the guide shaft passing hole 301 on each positioning block 3 matches the shaft diameter size of the corresponding guide shaft 4 at the position where the annular limiting clamping groove 401 is not formed. The aperture size of the small aperture portion 3011 of the guide shaft passing hole 301 on each positioning block 3 matches the shaft diameter size of the corresponding guide shaft 4 at the position where the annular limiting clamping groove 401 is formed. The positioning cylinder 2 in the embodiment is also a commercially available product. The action of the positioning cylinder 2 is controlled by an external controller. The driving end of the positioning cylinder 2 is in an extended state when the gas source is disconnected, thereby ensuring that the guide shaft 4 is effectively locked after the gas source is disconnected.
[0035] Specifically, the driving end of the lifting cylinder 004 is connected with the connecting platform 005 through a floating joint 5, which can adapt to a certain assembly error and stably drive the connecting platform 005 to lift.
[0036] Specifically, as shown in FIG. 1, the lifting cylinder 004 is connected with the connecting platform 005 through the floating joint 5. The connecting platform 005 is connected with the upper portions of the two guide shafts 4. The two guide shafts 4 are symmetrically arranged on the left and right sides of the lifting cylinder 004. The axial center lines of each guide shaft 4 are perpendicular to the horizontal plane. A plurality of annular limiting clamping grooves 401 are formed on each guide shaft 4 in the axial direction. The height positions of the annular limiting clamping grooves 401 on each guide shaft 4 correspond to the height positions of the annular limiting clamping grooves 401 on the other guide shafts 4 one by one. The widths of all the annular limiting clamping grooves 401 in the up-down direction are equal. The specific number and height position of each annular limiting clamping groove 401 can be adjusted as required. Figure 6As shown, in the embodiment, the driving end of each positioning cylinder 2 is connected with the corresponding positioning block 3 through a screw rod 7, and the two ends of each screw rod 7 are connected with the driving end of the corresponding positioning cylinder 2 and the positioning block 3 through threads, so that the screw rod 7 is convenient to disassemble and assemble. Each screw rod 7 is provided with a locking nut 8 through threads, and the locking nut 8 on the screw rod 7 is tightened to further ensure the connection reliability.
[0037] Specifically, as shown in Figure 5 and Figure 6 In the embodiment, each positioning cylinder mounting frame 1 includes a connecting vertical plate A 101, a connecting vertical plate B 102 and a connecting horizontal plate 103 which are connected together, the upper end of the connecting vertical plate A 101 of each positioning cylinder mounting frame 1 and the upper end of the connecting vertical plate B 102 of the positioning cylinder mounting frame 1 are fixedly connected with the lifting cylinder mounting frame 006 through screws, the lower end of the connecting vertical plate A 101 of each positioning cylinder mounting frame 1 and one end of the connecting horizontal plate 103 of the positioning cylinder mounting frame 1 are fixedly connected through screws, the lower end of the connecting vertical plate B 102 of each positioning cylinder mounting frame 1 and the other end of the connecting horizontal plate 103 of the positioning cylinder mounting frame 1 are fixedly connected through screws, the connecting vertical plate A 101 of each positioning cylinder mounting frame 1 is fixedly connected with the cylinder body of the corresponding positioning cylinder 2 through screws, and the bottom surface of each positioning block 3 is placed on the top surface of the connecting horizontal plate 103 of the corresponding positioning cylinder mounting frame 1, so that the structure is simple and convenient to disassemble and assemble.
[0038] In the embodiment, the connecting vertical plate B 102 of each positioning cylinder mounting frame 1 is provided with a guide pin shaft 9, and each guide pin shaft 9 penetrates into the inner side of the positioning block 3 on the connecting horizontal plate 103 of the corresponding positioning cylinder mounting frame 1. In the embodiment, the axial center lines of all guide pin shafts 9 are collinear. The arrangement of the guide pin shaft 9 can guide the horizontal movement of the positioning block 3, ensure the movement accuracy of the positioning block 3 and avoid the movement skew of the positioning block 3.
[0039] Specifically, in the embodiment, the lifting cylinder mounting frame 006 is further provided with a linear bearing 6 for each guide shaft 4 to pass through at the corresponding position of each guide shaft 4, and each linear bearing 6 is located above the positioning block 3 through which the corresponding guide shaft 4 passes. In the embodiment, the connecting horizontal plate 103 of each positioning cylinder mounting frame 1 is provided with a guide shaft sleeve 10 for the corresponding guide shaft 4 to pass through. Through the arrangement of the guide shaft 4, the linear bearing 6 and the guide shaft sleeve 10, the guide shaft 4 can move accurately and stably, and the connecting platform 005 can be stably lifted. As shown in Figure 7 The lower end opening of each guide shaft sleeve 10 is inwardly provided with an inclined chamfer, which can avoid the setting annular limiting clamping groove 401 of the guide shaft sleeve 10 from being clamped at the lower end opening of the guide shaft sleeve 10, but can smoothly slide into the guide shaft sleeve 10 along the inclined chamfer at the position, and further avoid the dislocation of the guide shaft 4.
[0040] Working principle:
[0041] In the process of driving the connecting platform 005 to normally lift, the driving end of each positioning cylinder 2 does not protrude, so that the guide shaft 4 always smoothly passes through the large aperture part 3012 of the guide shaft passing hole 301 of the positioning block 3; when the lifting cylinder 004 drives the connecting platform 005 to lift to the specified position, the driving end of each positioning cylinder 2 is controlled to protrude to drive the positioning block 3 to move horizontally, so that the guide shaft of the positioning block 3 passes through the small aperture part 3011 of the hole 301 and is clamped into the annular limiting clamping groove 401 at the corresponding height position of the guide shaft 4, which can lock the lifting action of the guide shaft 4, and by clamping the positioning block 3 into any annular limiting clamping groove 401, the connecting platform 005 can be fixed at the specified position; when the gas source is disconnected, the positioning block 3 still maintains the locking effect on the guide shaft 4, effectively avoiding the problem of sudden falling of the connecting platform 005 and the superconducting medium module 003, which may cause damage to the equipment.
