Description

Technical Field

[0001] The utility model relates to the field of ore flotation, in particular to a rare earth concentrate flotation device. Background Art

[0002] Rare earth beneficiation is the process of separating rare earths and minerals from rare earth-containing ores. Its beneficiation products include fluorocarbon cerium lanthanum concentrate, monazite concentrate and mixed rare earth concentrate. The bubble generator is used to make the minerals in the rare earth selectively adhere to the bubbles, thereby sorting and extracting the bubbles. Currently, rare earth ore sorting is generally carried out by flotation machines.

[0003] In existing rare earth concentrate flotation devices, when flotating rare earths, a large amount of minerals are easily adhered to the flotation plates, and the flotation plates are prone to discharge the liquid to be floated, resulting in poor flotation effect and difficulty in fully separating the minerals in the rare earths. In addition, during the flotation process, there is a situation where bubbles are not concentrated enough, resulting in insufficient scooping of bubbles and minerals by the flotation plates, resulting in insufficient flotation of rare earths and poor flotation effect. Utility Model Content

[0005] The technical solution of the utility model is: a rare earth concentrate flotation device, including a storage box, a feeding pipe, a discharge pipe, a valve, a fixed rod, a foam generator, a fixed frame, a motor, a flotation assembly and a scraper assembly, the top of the storage box is fixedly connected with the feeding pipe, the feeding pipe is communicated with the storage box, the lower part of the storage box is fixedly connected with the discharge pipe, the discharge pipe is communicated with the storage box, a valve is installed on the discharge pipe, the upper part of the inner wall of the storage box is fixedly connected with the fixed rod, the lower part of the inner wall of the storage box is fixedly connected with the foam generator, one side of the upper part of the storage box is fixedly connected with the fixed frame, the fixed frame is fixedly connected with the motor, the fixed rod is provided with a flotation assembly, the flotation assembly is provided with a scraper assembly, the flotation assembly is used to sort out minerals present in the rare earth, and the scraper assembly is used to reduce the adhesion of the minerals on the device, so that the rare earth is floated more fully.

[0006] Furthermore, the flotation assembly includes a driving gear, a rotating frame, a discharge net and a transmission gear. The driving gear is fixedly connected to the output shaft of the motor, the rotating frame is rotatably connected to the fixed rod, two discharge nets are fixedly connected to the rotating frame, and the two discharge nets are symmetrically arranged. A transmission gear is fixedly connected to one side of the rotating frame, and the transmission gear is engaged with the driving gear.

[0007] Furthermore, the scraper assembly includes a fixed block, a scraper frame, a return spring, a push rod and a protrusion. Four fixed blocks are fixedly connected to the rotating frame. The two fixed blocks on the same side form a group. The two fixed blocks in the same group are symmetrically arranged. A scraper frame is slidably connected between the two fixed blocks of each group. The scraper frame is in contact with the discharge net. A return spring is connected between the scraper frame and the two fixed blocks of each group. Two push rods are fixedly connected to the side where the two scraper frames are close to each other. Two protrusions are fixedly connected to the fixed rod. The two push rods on the same scraper frame are in contact with the two protrusions respectively.

[0008] Furthermore, the scraping frame is parallel to the discharge net, and the scraping frame is used to scrape the discharge net to reduce the minerals adhering to the discharge net.

[0010] The beneficial effects of the utility model are as follows: 1. The rotation of the discharge net causes the minerals attached to the bubbles to be discharged into the storage box. The discharge net can prevent the liquid from being pushed out during discharge. The rotation of the scraper frame will drive the return spring and the push rod to rotate. The rotation of the push rod will be lifted by the protrusion, causing the scraper frame to slide back and forth. The two scraper frames move away from each other, the return spring is stretched, and the scraper frame slides to scrape the minerals adhered to the discharge net back into the storage box. This reciprocating motion can reduce the minerals adhered to the discharge net, thereby quickly and fully screening out the minerals in the rare earth, and achieving a better flotation effect.

[0011] 2. The rotation of the turret will drive the active pulley to rotate, and the rotation of the active pulley will drive the passive pulley to rotate through the transmission belt. The rotation of the passive pulley will drive the push roller. The rotation of the push roller can move the bubbles on the surface of the storage box to the bottom of the turret and the discharge net, so that the bubbles move closer to the bottom of the turret and the discharge net, so that the minerals in the rare earth can be more fully floated, thereby achieving better flotation effect.
