[0001] The invention relates to the technical field of mineral processing, and in particular to a flotation machine for lepidolite mineral processing. Background Art

[0002] The flotation machine for lithium mica ore dressing is a device specially used for the selection of lithium mica ore. It meets different mineral processing needs through various models and specifications, such as SF type continuous aeration flotation machine, mechanical stirring flotation machine, etc. In specific applications, lithium mica ore is selected by flotation machine. The lithium mica concentrate after flotation is filtered and then treated to obtain the final lithium mica concentrate product. These flotation machines are widely used in the field of lithium mica beneficiation, providing strong support for the development and utilization of lithium resources.

[0003] In the process of lithium mica beneficiation, the surface area of ​​larger ore particles is relatively small, which makes it difficult for the flotation reagent to fully cover its surface, thereby reducing the flotation recovery rate of lithium mica. Due to the large particles, it is difficult for the reagent to contact with the lithium mica minerals wrapped inside the ore. Even if the lithium mica on the surface of the ore is acted upon by the reagent, it is difficult to effectively float the lithium mica inside the ore that has not been exposed to the reagent. Summary of the invention

[0004] The invention discloses a flotation machine for lepidolite beneficiation, which aims to solve the technical problem that when lepidolite is beneficiated, the ore particles are large and the surface area is small, so it is difficult for the flotation reagent to fully cover and reduce the recovery rate. Moreover, the large particles make it difficult for the reagent to reach the lepidolite wrapped inside, and even if the surface works, it is difficult to effectively float inside.

[0006] By providing a flotation machine body, an injection box shell, a connecting frame, a supporting bottom frame, a conveying pipeline, an isolation plate, a connecting fixed seat, an automatic rotating rod, a scraper flotation plate and a flotation platform, in the process of lepidolite beneficiation, the lepidolite ore is firstly injected into the injection box shell, and then crushed by the crushing component. The crushed lepidolite ore is transported to the inside of the flotation machine body through the conveying pipeline at the bottom of the injection box shell, and various required flotation reagents are added to the flotation machine body through the reagent box at the top of the flotation machine body and the reagent conveying pipe, so as to achieve accurate addition of reagents. Finally, the mixing component located inside the flotation machine body starts to operate, so that the slurry and the reagent are fully mixed and stirred in the flotation machine, so that the reagent is evenly distributed and fully in contact with the lepidolite particles. In the mixing and stirring process, the foaming agent generates a large number of stable bubbles, and as the bubbles carry the lepidolite particles to float above the flotation platform, the movable automatic rotating rod connected to the connecting fixed seat drives the outer symmetrical scraper flotation plate to achieve the preliminary separation of lepidolite and other impurity minerals.

[0007] In a preferred solution, the ore crushing assembly includes a driving motor 1, a power output shaft of the driving motor 1 is connected to a connecting rod 1 through a bearing transmission, a circular hole is provided on the connecting frame, and the connecting rod 1 is located inside the circular hole and is fixedly connected to a rotating gear, both sides of the rotating gear are movably connected with symmetrical gear rods, the gear rods and the rotating gear are meshed with a tooth groove 1, the top ends of the two symmetrically distributed gear rods are movably connected to a limited sliding groove, the top ends of the limited sliding grooves are fixedly connected to the bottom ends of the connecting frame, the opposite ends of the gear rods are fixedly connected to a connecting seat 1, the bottom ends of the connecting seat 1 are fixedly connected to a connecting rod 2, and the top ends of the connecting rods 2 away from the connecting seat 1 are fixedly connected to the connecting seat 2, and the connecting frame has symmetrical The top of the connecting seat two is located in the internal movably connected of the slide slot, the bottom ends of the two connecting rods two are symmetrically distributed are fixedly connected with a plurality of connecting round rods, the outer sides of the connecting round rods are fixedly connected with support plates, and the opposite sides of the support plates are fixedly connected with crushing plates, and the opposite sides of the symmetrical support plates are fixedly connected with electric telescopic driving rods, the front ends of the two electric telescopic driving rods symmetrically distributed are fixedly connected with the support seat one, the bottom ends of the support seat one are fixedly connected with connecting sliding rods, the top ends of the connecting sliding rods away from the support seat one are fixedly connected with the support seat two, and the bottom ends of the support seat two are fixedly connected with the telescopic rods, the bottom ends of the telescopic rods are fixedly connected to the front ends of the support plates, and the outer sides of the connecting sliding rods are movably connected with cleaning rollers.

[0008] By providing a crushing assembly, before the lepidolite beneficiation is carried out, the driving motor 1 is first started to drive the connecting rod 1 to rotate. The rotating gear fixedly connected to the connecting rod 1 rotates accordingly, and the rotating gear meshes with the gear rods symmetrical on both sides through the tooth groove 1, thereby driving the gear rod to move. The rotating gear rod moves in the limit sliding groove, and the limit sliding groove plays a limit guiding role in the movement of the gear rod. At the same time, the connecting rod 2 at the bottom end of the connecting seat 1 fixed on the opposite end of the gear rod also moves in conjunction. With the movement of the connecting rod 2, the multiple connecting round rods connected to its bottom end and the support plate fixed on the outside of the connecting round rod will also move accordingly. The crushing plate fixed on the opposite side of the support plate moves closer or farther away accordingly, realizing different degrees of crushing operation on the lepidolite ore, and the electric telescopic drive rod distributed on the opposite side of the support plate can be telescopic according to the crushing requirements. When the electric telescopic drive rod is extended or retracted, the cleaning roller movably connected to the outside of the connecting sliding rod will roll with the movement of the connecting sliding rod to clean the surface of the filter plate. During the process, the crushing component improves the mineral processing efficiency. Since the size of the crushed particles is more uniform, the flotation agent can more fully contact the surface of the lithium mica particles. The crushed small-particle ore can provide a larger contact area, making it easier for the leaching agent to react with lithium and other components in the ore, thereby improving the leaching efficiency and the flotation recovery rate.

[0009] In a preferred solution, a filter plate is provided below the ore crushing assembly, the outer side of the filter plate is fixedly connected to the inner side of the injection box shell, and a symmetrical reagent box is fixedly connected to the top of the flotation machine body, and a reagent delivery pipe is fixedly connected to the front end of the reagent box.

The movable gear at the front end of the rotating frame moves in the gear ring, and because the gear ring and the movable gear are meshed through the tooth groove 2, the movable gear moves in a circle around its center under the restriction of the gear ring. The connecting rotating shaft fixedly connected at the bottom end of the movable gear also makes circular motion accordingly, and the connecting rod movably connected to the bottom end of the connecting rotating shaft swings as the connecting rotating shaft makes circular motion, and the sliding seat fixedly connected at the front end of the connecting rod also moves accordingly. The movably connected support rod inside the sliding seat is fixed inside the rectangular hole of the rotating frame, which plays a role in limiting the position of the sliding seat, so that the sliding seat moves on a specific path, and the rotating shaft 2 drives the reagent tube and the reagent nozzle to rotate. At the same time, the rotating blades and the spoiler rotate in the slurry to stir and mix the lithium mica ore in the flotation machine body and the reagent sprayed from the reagent nozzle. The rotating blades mainly stir the slurry through the tangential force generated by rotation, and the spoiler will disrupt the flow direction of the slurry, so that the slurry and the reagent are fully contacted and mixed, thereby achieving a better mineral processing effect.

[0012] As can be seen from the above, the crushing component of the flotation machine for lithium mica ore dressing provided by the present invention improves the ore dressing efficiency. Since the particle size after crushing is more uniform, the flotation agent can more fully contact with the surface of the lithium mica particles. The crushed small particle ore can provide a larger contact area, making it easier for the leaching agent to react with lithium and other components in the ore, thereby improving the leaching efficiency and the flotation recovery rate.
