Description

Technical Field

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

[0002] In the rare earth smelting process, the raw ore is dissolved and reacted to form a solid precipitate, thus obtaining an effective enrichment.

[0003] Patent application number CN201820517388.6 discloses a rare earth precipitation device, including a tank body. A tank cover is bolted to the top of the tank body. An inlet is located on one side of the top of the tank cover. A motor is bolted to the center of the top of the tank cover. A stirring shaft is screwed to the other end of the motor, penetrating the tank cover and inserted into the tank body. A stirring rod is bolted to the outer surface of the stirring shaft. Two support rods are bolted to one side of the stirring shaft. A cleaning rod is bolted to the other side of the support rods. A scraper is located on the other side of the cleaning rod. A spring is installed between the cleaning rod and the scraper. A bracket is bolted to the outside of the tank body. An outlet is located at the bottom of the tank body. Filter screen blocks are welded inside the tank body, and filter screens are installed between the filter screen blocks. After the reaction, the precipitate falls onto the filter screen, filtering and precipitating the rare earth elements. In this type of rare earth precipitation device, the liquid flows from top to bottom, causing the precipitate to accumulate entirely on the filter screen. This results in a slow filtration speed and easily leads to filter screen clogging, affecting the filtration rate of the precipitation.

[0004] This invention was developed to address 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 precipitation device.

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

[0007] This invention discloses a rare earth precipitation device, comprising a reaction vessel fixed on a frame, a feed pipe fixed on the reaction vessel, a stirring motor fixed on the reaction vessel, the output end of the stirring motor fixed to a stirring shaft inside the reaction vessel, stirring blades fixed on the stirring shaft, a feeding spiral blade fixed at the bottom of the stirring shaft, a connecting pipe with a valve fixed at the bottom of the reaction vessel, a filter pipe fixed at the bottom of the connecting pipe, filter holes evenly arranged through the filter pipe, a rotating shaft installed inside the filter pipe, the rotating shaft being driven to rotate by the filter motor, a water-filtering spiral blade spirally fixed on the rotating shaft, and a discharge pipe with a valve fixed at the end of the filter pipe. The raw materials for the reaction are discharged into the reactor through the feed pipe. The stirring shaft is driven by a stirring motor to rotate, and the raw materials are stirred by the stirring blades. After the reaction, the valve on the connecting pipe is opened, and both the precipitate and the solution are discharged into the filter tube. The solution is discharged through the filter holes on the filter tube, while the precipitate remains in the filter tube. The filtration spiral blade is driven by a filtration motor to rotate. When the filtration spiral blade rotates, it pushes the precipitate to move towards one end of the filter tube, which can prevent the precipitate from clogging the filter holes and affecting the filtration effect. The precipitate is also squeezed into the filter tube at the outlet pipe position. The precipitate is squeezed out, and the solution inside the precipitate is expelled. After filtration is completed, the valve on the outlet pipe is opened, and the precipitate is discharged and collected through the outlet pipe. This device can separate the precipitate and the solution. The rotation of the filtration spiral blade pushes the precipitate in the filter tube to move, which can prevent the precipitate from clogging the filter holes and affecting the filtration effect. Furthermore, the filtration is accelerated by pressure filtration, which squeezes out the solution inside the precipitate, further improving the filtration speed.

[0008] Preferably, a scraper that mates with the inner wall of the reactor is fixed on the stirring shaft.

[0009] Preferably, a collection box is also fixed on the frame below the filter tube, and a partition is also fixed inside the collection box. The partition divides the collection box into two chambers, one chamber for collecting the solution and the other chamber for collecting the precipitate.

[0010] Preferably, the filter tube is fixed at an angle on the frame.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device can separate the precipitate from the solution, and the rotating water-filtering spiral blades can move the precipitate in the filter tube to prevent the precipitate from clogging the filter holes and affecting the filtration effect. Furthermore, the pressure filtration method can accelerate the filtration by squeezing out the solution from the precipitate, thereby further improving the filtration speed.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0019] Example 1:

[0020] like Figures 1 to 3 As shown, this embodiment discloses a rare earth precipitation device, including a reactor 1 fixed on a frame (not shown), a feed pipe 2 fixed on the reactor 1, a stirring motor 3 fixed on the reactor 1, the output end of the stirring motor 3 fixed to a stirring shaft 5 inside the reactor 1, a stirring blade 6 fixed on the stirring shaft 5, a feeding spiral blade 8 fixed at the bottom of the stirring shaft 5, a connecting pipe 4 with a valve fixed at the bottom of the reactor 1, a filter pipe 9 fixed at the bottom of the connecting pipe 4, filter holes 10 evenly arranged through the filter pipe 9, a rotating shaft 11 also provided inside the filter pipe 9, the rotating shaft 11 is driven to rotate by a filter motor 12, a water filtering spiral blade 13 is also spirally fixed on the rotating shaft 11, and a discharge pipe 14 with a valve is also fixed at the end of the filter pipe 9. The raw materials for the reaction are discharged into the reaction vessel 1 through the feed pipe 2. The stirring shaft 5 is driven to rotate by the stirring motor 3, and the raw materials are stirred by the stirring blades 6. After the reaction, the valve on the connecting pipe 4 is opened, and both the precipitate and the solution are discharged into the filter tube 9. The solution is discharged through the filter holes 10 on the filter tube 9, while the precipitate remains in the filter tube 9. The water-filtering spiral blade 13 is driven to rotate by the filtration motor 12. When the water-filtering spiral blade 13 rotates, it pushes the precipitate to move towards one end of the filter tube 9, which can prevent the precipitate from clogging the filter holes 10 and affecting the filtration effect. The precipitate is also squeezed into the filter tube 9 at the outlet pipe 14. The precipitate is squeezed and the solution inside the precipitate is expelled. After filtration is completed, the valve on the outlet pipe 14 is opened, and the precipitate is discharged and collected through the outlet pipe 14. This device can separate the precipitate and the solution. The rotation of the water-filtering spiral blade 13 pushes the precipitate in the filter tube 9 to move, which prevents the precipitate from clogging the filter holes 10 and affecting the filtration effect. Furthermore, the filtration is accelerated by pressure filtration, which squeezes out the solution inside the precipitate, further improving the filtration speed.

[0021] Among them, a scraper 7 is fixed on the stirring shaft 5 to be used in conjunction with the inner wall of the reaction vessel 1.

[0022] The filter tube 9 is fixed at an angle on the frame.

The partition 16 divides the collection box 15 into two chambers, one chamber for collecting the solution and the other chamber for collecting the precipitate.

[0025] 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.
