Description

Technical Field

[0001] The utility model belongs to the technical field of purifying and stirring praseodymium-neodymium oxide mixed acid, and more specifically, particularly relates to an improved stirring rod for purifying praseodymium-neodymium oxide mixed acid. Background Art

[0002] At present, in the existing workshop praseodymium-neodymium oxide mixed acid purification operation, the commonly used stirring rod structure is as follows Figure 5 As shown, the adapter lock is connected to the driving end of the rotating device through a locating pin, and a transfer rod is arranged at the bottom of the adapter lock. Both the adapter lock and the transfer rod are made of metal, so they cannot directly contact the acid solution. A polytetrafluoroethylene adapter cylinder is installed on the outside of the adapter rod to isolate the metal adapter rod from contact with the acid solution. The adapter rod and the adapter cylinder are connected and fixed by multiple pins, and the hole is sealed by sealant. A rotating head is arranged at the bottom of the adapter cylinder, and symmetrical stirring blades are arranged on the outer circumference of the rotating head to stir and mix the acid solution.

[0003] However, although the adapter tube and the adapter rod fixed by multiple pins have good connectivity, the sockets on the sides of the adapter tube need to be sealed. Acid can easily enter during the praseodymium-neodymium mixed acid oxidation process, causing corrosion reaction of the pins, resulting in separation of the adapter rod and the adapter tube, affecting the stirring operation. Since the rotating head has stirring blades fixed on both sides, stirring can be performed, but the force is uneven. During high-speed rotation, the stirring blades are easily broken, the stability is poor, the service life is short, and the overall structure is cumbersome to install. Utility Model Content

[0011] The utility model provides an improved stirring rod for purifying praseodymium-neodymium oxide mixed acid, which has the following beneficial effects:

[0012] By setting a positioning rod, the positioning rod adopts a rectangular structure design, which can be plugged and assembled with the adapter tube, and while ensuring the stability of rotation, it can also ensure the rotation synchronization of the positioning plate and the adapter tube. There is no need for a positioning pin, which reduces the sealing surface and improves the overall sealing. A glue coating groove is provided on the top of the adapter tube, and a special sealant can be filled into the glue coating groove to fix the adapter rod and the adapter tube. Compared with the previous positioning pin fixed with the sealant sealing method, the sealing is stronger and leakage is avoided.

[0022] See also Figures 1 to 5The utility model provides a technical solution: an improved stirring rod for purifying praseodymium-neodymium oxide mixed acid, comprising an adapter lock 1, which is connected and fixed to the driving end of a rotating device through a positioning pin 101, and a transfer rod 2 is welded at the bottom of the transfer lock 1. The transfer rod 2 and the transfer lock 1 are both made of metal. A positioning rod 201 is arranged at the bottom of the transfer rod 2. The positioning rod 201 is a rectangular parallelepiped as a whole, and has a square cross-section. A transfer tube 3 is fixedly assembled on the outer side of the transfer rod 2. The positioning rod 201 adopts a rectangular parallelepiped structure design, which can be plugged and assembled with the transfer tube 3, and the rotation stability and the rotation synchronization of the positioning plate and the transfer tube 3 are ensured. No positioning pin is required, the sealing surface is reduced, and the overall sealing is improved. The transfer tube 3 adopts PTFE material, also known as polytetrafluoroethylene: it has the advantages of being resistant to acid and alkali, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene is resistant to high temperatures and can protect the internal metal transfer rod 2 during the stirring process, thereby preventing the metal transfer rod 2 from being corroded by the mixed acid.

[0023] A glue coating groove 301 is provided on the top of the adapter tube 3, and a special sealant can be filled into the glue coating groove 301 to fix the adapter rod 2 and the adapter tube 3. Compared with the previous positioning pin fixing and sealant sealing method, the sealing is stronger, leakage is avoided, and the service life of the stirring rod is increased. The bottom of the adapter tube 3 is fastened with a rotating head 5, and the connection between the adapter tube 3 and the rotating head 5 is sealed and fixed by a special sealant.

[0024] A symmetrical slot is provided on the rotating head 5, and the slot is T-shaped. A stirring blade 501 is fixed in the slot. The cross-section of the stirring blade 501 is T-shaped, and the upper left corner of one of the stirring blades 501 is a chamfered angle 5011, and the lower right corner of the other stirring blade 501 is a chamfered angle 5011, thereby reducing the stirring resistance and increasing the stirring speed. By installing and fixing the stirring blade 501 inside the rotating head 5, the overall stability is improved, and the phenomenon of the stirring blade 501 breaking during rotation is avoided, and the service life is longer. A positioning plate 6 is provided on the top of the rotating head 5. The positioning plate 6 is annular as a whole and fits on the top of the rotating head 5. The rotating head 5 and the positioning plate 6 are sealed and fixed by sealant. The connection between the positioning plate 6 and the adapter tube 3 is also sealed and fixed by sealant, so that the overall connection is tighter.

[0025] The specific usage and function of this embodiment are as follows: first, the positioning rod 201 is quickly inserted into the adapter tube 3 and sealed and fixed, and then the rotating head 5 is sealed and fixed to the bottom of the adapter tube 3, and the T-shaped stirring blade 501 is symmetrically installed in the slot, so that the stirring blade 501 is set in the rotating head 5 to avoid being set on the outside without being subjected to force, and the stirring blade 501 is further sealed by the positioning pressure plate 6, and is further sealed and fixed with the rotating head 5 and the adapter tube 3 by the positioning pressure plate 6, which greatly improves the overall sealing performance and avoids the leakage of mixed acid and the contact reaction with the internal adapter rod 2, and finally the rotating lock is connected to the driving end of the rotating equipment at the top through the positioning pin 101 to stir the mixed acid.
