Description

Technical Field

[0001] This invention relates to the field of rare earth production equipment, and more particularly to a rare earth dissolution device. Background Technology

[0002] Rare earth elements are a collective term for seventeen metallic elements, including the lanthanides and scandium / yttrium, found in the periodic table. There are 250 rare earth minerals in nature. The first to discover rare earth elements was the Finnish chemist Gadolin. In 1794, he isolated the first rare earth "element" from a heavy ore resembling bitumen. Because few rare earth minerals were discovered in the 18th century, only small amounts of water-insoluble oxides could be produced chemically at that time. Historically, these oxides were conventionally called "earth," hence the name rare earth. The mined rare earth ores contain only a few percent, or even less, of rare earth oxides. To meet the production requirements of smelting, beneficiation is performed before smelting to separate rare earth minerals from gangue minerals and other useful minerals, thereby increasing the rare earth oxide content and obtaining rare earth concentrates that meet the requirements of rare earth metallurgy.

[0003] Patent application number CN201820695860.5 discloses a rare earth dissolving tank. The rare earth to be dissolved is placed in the tank, and air is intermittently introduced into the tank through an air inlet pipe on one side to generate bubbles. The bubbles impact the rare earth, accelerating the dissolution. However, the rare earth has a certain degree of viscosity, and the airflow can only impact the rare earth on the surface, requiring a long time to completely dissolve the rare earth.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rare earth dissolution device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a rare earth dissolving device, comprising a dissolving tank with an open top, a dissolving tube disposed inside the dissolving tank, a rotating shaft disposed inside the dissolving tube, the rotating shaft being driven to rotate by a motor, a spiral blade fixed on the rotating shaft, filter holes evenly disposed on the dissolving tube, a feed hopper fixed on the dissolving tube, and partitions connecting both sides of the dissolving tube to the dissolving tank, a drain pipe with a valve fixed at the bottom of the dissolving tank, a return pipe fixed on the dissolving tank, the bottom of the return pipe being fixed to the dissolving tank below the dissolving tube, the top of the return pipe being fixed to the dissolving tank above the dissolving tube, a water pump fixed on the return pipe, and a slag discharge pipe with a valve fixed at the end of the dissolving tube. The rare earth to be dissolved is discharged into the dissolving tube through the feed hopper, and the dissolving liquid is discharged into the dissolving tank. After the dissolving liquid submerges the dissolving tube, the rotating shaft driven by the motor rotates back and forth, and the spiral blades rotate with the rotating shaft. The spiral blades rotate clockwise and then counterclockwise, and the rare earth moves left and right in the dissolving tube and in the dissolving liquid, thus dissolving the rare earth. The dissolving liquid below the dissolving tube is drawn by a water pump and discharged into the dissolving tank above the dissolving tube through a return pipe. After the water pump draws out the dissolving liquid below the dissolving tube, the dissolving liquid above the dissolving tube quickly passes through the filter holes and enters the dissolving tube again, and is discharged through the filter holes below the dissolving tube. The dissolving liquid forms a water flow to flush the rare earth, which can effectively accelerate the dissolution of rare earth. This device uses the spiral blades to drive the rare earth to move and collide with the dissolving liquid, so as to achieve rapid dissolution of rare earth. The water pump draws out the dissolving liquid, which can form a water flow to flush the rare earth, which can effectively accelerate the dissolution of rare earth.

[0008] Compared with existing technologies, the present invention has the following advantages:

[0009] This device uses a spiral blade to move rare earth elements in a solution, allowing them to collide and mix, thus achieving rapid dissolution. Furthermore, by using a water pump to extract the solution, a water flow can be formed to flush the rare earth elements, effectively accelerating the dissolution process. Attached Figure Description

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0016] like Figures 1 to 3 As shown, this embodiment discloses a rare earth dissolving device, including a dissolving tank 1 with an open top, a dissolving tube 2 inside the dissolving tank 1, a rotating shaft 4 inside the dissolving tube 2, the rotating shaft 4 being driven to rotate by a motor 6, a spiral blade 5 fixed on the rotating shaft 4, filter holes 3 evenly arranged on the dissolving tube 2, a feed hopper 8 fixed on the dissolving tube 2, both sides of the dissolving tube 2 being connected to the dissolving tank 1 through partitions 7, a drain pipe 10 with a valve fixed at the bottom of the dissolving tank 1, a return pipe 11 fixed on the dissolving tank 1, the bottom of the return pipe 11 being fixed to the dissolving tank 1 below the dissolving tube 2, the top of the return pipe 11 being fixed to the dissolving tank 1 above the dissolving tube 2, a water pump 12 fixed on the return pipe 11, and a slag discharge pipe 9 with a valve fixed at the end of the dissolving tube 2. The rare earth to be dissolved is discharged into the dissolving pipe 2 through the feed hopper 8, and the dissolving liquid is discharged into the dissolving tank 1. After the dissolving liquid submerges the dissolving pipe 2, the rotating shaft 4 is driven by the motor 6 to rotate back and forth. The spiral blade 5 rotates with the rotating shaft 4. The spiral blade 5 rotates clockwise and then counterclockwise. The rare earth moves left and right in the dissolving pipe 2 and moves in the dissolving liquid, thus dissolving the rare earth. The dissolving liquid below the dissolving pipe 2 is then drawn by the water pump 12 and discharged into the dissolving tank 1 above the dissolving pipe 2 through the return pipe 11. The water pump 12 draws out the dissolving liquid from the dissolving pipe 2. After the dissolving liquid at the bottom, the dissolving liquid above the dissolving tube 2 quickly passes through the filter hole 3 and enters the dissolving tube 2, and then exits through the filter hole 3 at the bottom of the dissolving tube 2. The dissolving liquid forms a water flow to flush the rare earth in the dissolving tube 2, which can effectively accelerate the dissolution of rare earth. This device uses the spiral blade 5 to drive the rare earth to move in the dissolving liquid and collide and mix with the dissolving liquid to achieve rapid dissolution of rare earth. In addition, the water pump 12 extracts the dissolving liquid, which can form a water flow to flush the rare earth, which can effectively accelerate the dissolution of rare earth.

[0017] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
