Description

Technical Field

[0001] This utility model relates to the field of rare earth oxide production technology, and in particular to a rare earth oxide production equipment. Background Technology

[0002] Rare earth element oxides refer to the oxides of 15 lanthanide elements with atomic numbers 57 to 71 in the periodic table, such as cerium oxide. Cerium oxide is an inorganic compound with the chemical formula CeO2. It is a pale yellow or yellowish-brown powder. Cerium dioxide can be prepared by heating cerium, cerium hydroxide, or cerium oxalate in air.

[0003] A search revealed Chinese Patent Publication No. CN220835519U, which discloses an automatic production equipment for rare earth oxides. This utility model incorporates a stirring assembly. A servo motor drives a rotating drum, which in turn drives a vertical rod. This causes multiple stirring blocks on the vertical rod to agitate cerium oxalate, churning the accumulated cerium oxalate while simultaneously dispersing and spreading it evenly. This ensures uniform heating of the cerium oxalate, avoiding excessively low heating efficiency and prolonged heating time. The stirring blocks on the two support plates are staggered, ensuring that the circular trajectories of all the stirring blocks are different, thus increasing the range of agitation of the cerium oxalate.

[0004] The aforementioned patent uses the rotation of a vertical rod in conjunction with multiple agitator blocks to disperse and flatten piled oxalic acid. However, gaps exist between adjacent agitator blocks, preventing the cerium oxalate from being pushed forward. This leads to cerium oxalate accumulation in the gaps between the agitator blocks, resulting in uneven distribution and spreading of cerium oxalate, affecting the uniformity and efficiency of heating. Therefore, a rare earth oxide production device is proposed to solve these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a rare earth oxide production equipment, including a base 1. A heating plate 2 is fixedly connected to the inner wall of the base 1. The heating plate 2 is a device that converts electrical energy into heat energy to heat objects. It belongs to an application of electric heating technology and is existing technology, so it will not be described in detail here. A support leg 3 is fixedly connected to the bottom of the base 1. An electric push rod 4 is fixedly connected to the outer wall of the support leg 3. A top cover 5 is fixedly connected to the output end of the electric push rod 4. Activating the electric push rod 4 can drive the top cover 5 to move up and down. When the top cover 5 moves upward and exposes the heating plate 2, cerium oxalate can be added to the heating plate 2, or the cerium oxalate that has been heated on the heating plate 2 can be removed. The top cover 5 is provided with a material leveling mechanism 6 and a material turning mechanism 7.

[0035] Reference Figures 2-4 The material leveling mechanism 6 includes a motor 61, which is fixedly connected to the top of the top cover 5. The output end of the motor 61 is fixedly connected to a rotating shaft 62, and the bottom of the rotating shaft 62 is fixedly connected to a boss 63. During the heating process of cerium oxalate, the motor 61 is started to drive the rotating shaft 62 to rotate. While the rotating shaft 62 is rotating, it will drive the boss 63 to move synchronously. The inner wall of the boss 63 is slidably connected to a sliding plate 64. While the rotating shaft 62 drives the boss 63 to rotate, the boss 63 will drive the sliding plate 64 to make a circular motion around the rotating shaft 62. The lower surface of the sliding plate 64 is fixedly connected to a lever 65. While the sliding plate 64 is making a circular motion around the rotating shaft 62, the lever 65 can be used to push the cerium oxalate flat to prevent it from piling up. While the sliding plate 64 is sliding back and forth, it can cooperate with the lever 65 to push the cerium oxalate in the gap between two adjacent levers 65 flat.

[0036] Reference Figure 3 A transmission rod 67 is rotatably connected through the top of the boss 63. An eccentric wheel 68 is fixedly connected to the outer wall of the transmission rod 67. When the transmission rod 67 rotates, it drives the eccentric wheel 68 to rotate synchronously. An L-plate 66 is fixedly connected to the upper surface of the slide plate 64. Two sets of L-plates 66 are provided. The side of the two sets of L-plates 66 adjacent to each other is in contact with the side wall of the eccentric wheel 68. When the eccentric wheel 68 rotates, it periodically pushes the two sets of L-plates 66, so that the L-plates 66 drive the slide plate 64 to slide back and forth on the inner wall of the boss 63.

[0037] Reference Figure 6 The top of the transmission rod 67 is fixedly connected to the drive gear 69, and the top of the inner wall of the top cover 5 is fixedly connected to the fixed gear 610. The drive gear 69 meshes with the fixed gear 610. While the transmission rod 67 is making circular motion around the rotating shaft 62, it can drive the transmission rod 67 to rotate by cooperating with the drive gear 69 and the fixed gear 610.

[0038] Reference Figures 2-4The material turning mechanism 7 includes a shovel plate 71, which is fixedly connected to the side wall of the boss 63. The angle between the shovel plate 71 and the heating plate 2 is 8°. The lower surface of the shovel plate 71 is attached to the upper surface of the heating plate 2. During the rotation of the boss 63 driven by the rotating shaft 62, the boss 63 will drive the shovel plate 71 to rotate synchronously. At this time, the shovel plate 71 will shovel up the cerium oxalate laid on the heating plate 2. The side wall of the boss 63 is rotatably connected to a rotating rod 72. The outer wall of the rotating rod 72 is fixedly connected to a flip plate 73. The cross-section of the flip plate 73 is "L". The cerium oxalate falling from the shovel plate 71 can enter the interior of the flip plate 73 through the "L" shaped flip plate 73. By rotating the flip plate 73, the cerium oxalate placed inside can be flipped over and fall back onto the heating plate 2.

[0039] Reference Figure 5 A driven bevel gear 74 is fixedly connected to one end of the rotating rod 72 near the transmission rod 67, and a driving bevel gear 75 is fixedly connected to the outer wall of the transmission rod 67. When the transmission rod 67 rotates, it will drive the driving bevel gear 75 to rotate synchronously. The driving bevel gear 75 meshes with the driven bevel gear 74. When the transmission rod 67 rotates, the meshing driving bevel gear 75 and driven bevel gear 74 can drive the rotating rod 72 to rotate synchronously.

[0040] Working principle: Activating the electric push rod 4 can drive the top cover 5 to move up and down. When the top cover 5 moves upward and exposes the heating plate 2, cerium oxalate can be added to the heating plate 2, or the cerium oxalate that has been heated on the heating plate 2 can be removed. After adding cerium oxalate to the heating plate 2, activate the electric push rod 4 to move downward so that its bottom end fits against the top of the base 1. At this time, the top cover 5 can cover the top of the base 1, and at the same time, the heating plate 2 is activated to heat the cerium oxalate placed on its upper surface.

[0041] During the heating process of cerium oxalate, the motor 61 starts and drives the rotating shaft 62 to rotate. Simultaneously, the rotating shaft 62 drives the boss 63 to move synchronously. At this time, the boss 63 drives the sliding plate 64 to perform a circular motion around the rotating shaft 62. Simultaneously, the lever 65 at the bottom of the sliding plate 64 pushes the cerium oxalate placed on the heating plate 2, thus flattening the cerium oxalate and preventing it from piling up. At the same time, as the rotating shaft 62 drives the boss 63 to move, the boss 63 drives the transmission rod 67 to perform a circular motion around the rotating shaft 62. At this time, the fixed gear 610 drives the drive gear 69 at the top of the transmission rod 67 to rotate. Simultaneously, the drive gear 69 rotates... The transmission rod 67 will rotate synchronously, and the transmission rod 67 will drive the eccentric wheel 68 to rotate synchronously. The eccentric wheel 68 will periodically push the two sets of L plates 66, causing the L plates 66 to drive the slide plate 64 to slide back and forth on the inner wall of the boss 63. As the slide plate 64 slides back and forth, it will drive the lever 65 on its lower surface to move back and forth synchronously. The reciprocating movement of the lever 65 can push the cerium oxalate in the gap between two adjacent levers 65 to flatten it, so that the cerium oxalate accumulated on the heating plate 2 can be evenly dispersed and spread, so that the cerium oxalate can be heated evenly, which is beneficial to improving the heating efficiency of cerium oxalate.

[0042] While the transmission rod 67 rotates, it engages with the meshing drive bevel gear 75 and driven bevel gear 74 to drive the rotating rod 72 to rotate synchronously. As the rotating rod 72 rotates, it drives the three sets of flip plates 73 to rotate synchronously. At the same time, as the rotating shaft 62 drives the boss 63 to rotate, the boss 63 drives the shovel plate 71 to rotate synchronously. At this time, the shovel plate 71 will scoop up the cerium oxalate laid on the heating plate 2. As the shovel plate 71 rotates, the cerium oxalate scooped up by the shovel plate 71 will be pushed towards the rotating rod 72, so that the cerium oxalate falls into the inside of the flip plate 73 on the outer wall of the rotating rod 72. As the flip plate 73 rotates, it will turn the cerium oxalate placed inside over and let it fall back onto the heating plate 2, thereby turning over the cerium oxalate that is being heated, and further improving the heating uniformity of the cerium oxalate.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
