Description

Technical Field

[0001] The present application relates to the technical field of lithium ore sampling devices, and in particular to a lithium concentrate sampling device. Background Art

[0002] Lithium concentrate is an ore with a high lithium content and is the primary raw material for the production of lithium salts such as lithium carbonate and lithium hydroxide, which are in turn crucial ingredients for lithium batteries. During the lithium concentrate production process, the ore is typically processed through crushing and grinding to a specific particle size range to facilitate subsequent beneficiation processes such as flotation and magnetic separation, as well as the final production of lithium salts. During mining and initial processing, lithium-containing ores such as spodumene are processed through crushers to reduce them to a smaller particle size.

[0003] During the production of lithium concentrate, it is often necessary to sample the concentrate for testing. However, existing lithium concentrate sampling methods typically use a sampling tube to manually sample the concentrate, making it difficult to control the sample volume and subjecting the sample to many limitations. Utility Model Content

[0018] Beneficial effects that this application can achieve:

[0019] A lithium concentrate sampling device proposed in an embodiment of the present application is configured such that a sampling tube is rotatably arranged on a support frame. When the notch of the receiving slot of the sampling tube faces downward, the contact area between the notch of the sampling tube and the lithium concentrate is small, making it easier for the sampling tube to be inserted into the lithium concentrate, allowing the lithium concentrate to enter the receiving slot. A baffle assembly is provided on the support frame, and the baffle assembly cooperates with the support frame to fix the sampling tube, so that the notch of the sampling tube can be maintained in a downward state, ensuring that the sampling tube can be vertically inserted downward into the lithium concentrate pile.

At this time, the baffle assembly rotates and blocks the notch, so that the lithium concentrate in the receiving slot will not fall from the notch, and the lithium concentrate can be sampled smoothly.

[0031] Example 1

[0032] Reference Figure 1-Figure 5 ,in Figure 1 The notch of the accommodating groove of the sampling tube is in a downward-facing state, and the baffle assembly blocks the notch; Figure 2 for Figure 1 A side view of the structure, in which the notch faces downward and the blocking plate blocks the notch; Figure 4 The notch is in the downward state, at this time the connecting rod and the side guard plate cooperate to limit the limiting protrusion to maintain the notch in the downward state; Figure 5 The slot is facing upwards, and the blocking plate blocks the slot. Figure 4 The baffle assembly is rotated clockwise by a certain angle to obtain Figure 2 The status shown, Figure 2 The baffle assembly drives the sampling tube to rotate clockwise for a certain angle to obtain Figure 5 The status shown.

[0033] The first embodiment of the present application provides a lithium concentrate sampling device, comprising: a sampling tube 10 and a support frame 20. The sampling tube 10 has a receiving tank 11 for receiving lithium concentrate; the support frame 20 is used to support the sampling tube 10, and the sampling tube 10 is provided with a rotating shaft 13 on both radial outer walls. The rotating shaft 13 is rotatably connected to the support frame 20 to adjust the position of the slot of the receiving tank 11; wherein, the support frame 20 is provided with a rotatable baffle assembly 30, which can selectively cooperate with the support frame 20 and the end of the sampling tube 10 away from the slot to form a limiting structure, so that the slot can be maintained in a downward-facing state, or the slot can be blocked to prevent the lithium concentrate in the receiving tank 11 from moving out of the slot.

[0034] In this embodiment, the sampling tube 10 is a cylindrical structure with one end open and the other end sealed. When the sampling tube 10 is sampling, the notch of the sampling tube 10 faces downward. When the sampling tube 10 is inserted into the lithium concentrate pile, the contact area between the sampling tube 10 and the lithium concentrate pile is the wall thickness area of ​​the sampling tube 10. Compared with the case where the sampling tube 10 is inserted vertically downward into the lithium concentrate pile with the notch facing upward, the contact area is smaller, making it easier for the sampling tube 10 to be inserted into the lithium concentrate, and the sampling tube 10 does not need to be completely immersed in the lithium concentrate pile. During the sampling process, the notch of the sampling tube 10 is first directed downward. At this time, the baffle assembly 30 is in an unblocked notch state, and at this time, the baffle assembly 30 cooperates with the support frame 20 to limit the upper end of the sampling tube 10, so that the sampling tube 10 maintains the notch facing downward, reducing the possibility of the sampling tube 10 shaking at will. After the sampling tube 10 moves downward a certain distance, the lithium concentrate is filled into the receiving groove 11. At this time, the plugging assembly rotates clockwise a certain angle. After the plugging plate 32 blocks the notch, the sampling tube 10 can be moved upward to remove the lithium concentrate sample. Alternatively, the notch can be kept blocked and the sampling tube 10 can be driven to rotate a certain angle to keep the lithium concentrate contained in the receiving groove 11. The notch of the receiving groove 11 is the tube mouth of the sampling tube 10, and the lithium concentrate through-hole 211 notches into the receiving cavity.

[0037] In this embodiment, two side guard plates 22 are provided, and the two ends of the sampling tube 10 are connected to the two side guard plates 22 via the rotating shaft 13, thereby improving the stability of the sampling tube 10 during rotation. The positioning plate 21 supports the entire structure. During use, external force can be applied directly to the positioning plate 21, or the positioning plate 21 can be mounted on a structure such as a robot.

[0040] In this embodiment, the blocking plate 32 is a plate-like structure. One end of the blocking plate 32 is connected to the connecting rod 31, and the other end of the blocking plate 32 is a free end. During rotation, the blocking plate 32 moves from the free end of the blocking plate 32 toward the notch. Two connecting rods 31 are located outside the sampling tube, and the ends of the connecting rods 31 are fixedly connected to the positioning column 33 and the blocking plate 32, respectively. Raised structures can be provided on both sides of the blocking plate 32, and the connecting rods 31 are connected to the raised structures to improve the stability of the connection.

[0043] In this embodiment, the limiting protrusion 40 may be a cylindrical structure, and the limiting protrusion 40 may be connected to the outer wall of the sampling tube 10 by welding, bonding, or screws. When the limiting protrusion 40 is in contact with the side guard plate 22, the connecting rod 31 and the side guard plate 22 are in contact with each other to prevent the two from moving further.

At this time, the blocking plate 32 blocks the notch. As the blocking plate 32 continues to move, it can drive the sampling tube 10 to continue to flip, that is, change the orientation of the notch, tilting the notch upward, and reducing the pressure exerted by the lithium concentrate in the accommodating tank 11 on the blocking plate 32. At the same time, the limiting plate 14 can also position the blocking plate 32, preventing it from crossing the notch and causing it to lose its blocking effect on the notch.

By providing a detachable lock pin 213 on the positioning plate 21, when the limiting hole 61 on the rack 60 is aligned with the lock hole 212, the relative fixation of the rack 60 and the positioning plate 21 is achieved by inserting the lock pin 213, so as to maintain the relative position of the rack 60 unchanged, thereby maintaining the position state of the blocking plate 32. A plurality of limiting holes 61 are provided on the rack 60. When the rack 60 is at different heights, it can be fixed by the limiting holes 61. The lock pin 213 and the lock hole 212 are threaded.
