Description

Technical Field

[0001] This utility model relates to the field of rare earth element extraction technology, and in particular to a praseodymium-neodymium oxide sieving and mixing device. Background Technology

[0002] Construction waste contains a certain amount of rare earth elements, especially waste from electronic waste, glass products, and certain special building materials. Although the rare earth content in these wastes is relatively low, resources can be reused through efficient extraction technologies. For construction waste containing rare earth elements, an improved acid leaching-extraction process can be used to obtain oxides after precipitation and calcination; praseodymium-neodymium oxide is one such oxide.

[0003] The calcination process typically involves placing the powder precipitate in a calcination box. After calcination, the praseodymium and neodymium oxides are usually placed in the box as a whole agglomerated mass. They need to be sieved and mixed to obtain powder. Current sieving and mixing devices cannot automatically remove the blocky oxides from the box, nor can they quickly break up the blocky oxides during the sieving and mixing process, resulting in low continuous sieving and mixing efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a praseodymium-neodymium oxide screening and mixing device. This device can continuously and automatically crush blocky oxides in the incineration box, and then use a rotating impact crushing method to quickly complete the screening and mixing process with high efficiency.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A praseodymium-neodymium oxide screening and mixing device includes a pair of hanging rails, a conveyor belt installed above the pair of hanging rails, and multiple push plates for pushing a burning box fixed at intervals on the surface of the conveyor belt. A base is installed below the pair of hanging rails, and a rotatable screen barrel is installed on the base. Multiple crushing rods are fixedly connected to the circumferential inner wall of the screen barrel. A liftable material distribution seat is installed at the opening of the screen barrel, and three threaded drills are rotatably connected to the material distribution seat. A guide cylinder cover is fitted around the screen barrel.

[0007] Preferably, the distance between the pair of hanging rails is less than the length of the incineration box.

[0008] Preferably, a rotating drum is rotatably connected to the base, the top of the rotating drum is fixedly connected to the bottom of the sieve barrel, a first motor is installed on the base, and pulleys are fixed to both the output end of the first motor and the rotating drum, with a belt sleeved between the pulleys.

[0009] Preferably, a conical seat is fixed to the inner bottom of the screen barrel, and the inner wall of the guide cylinder cover is inclined, corresponding to the bottom of the conical seat.

[0010] Preferably, a cylinder is fixedly installed on the base inside the rotating cylinder, a push rod is fixed to the telescopic end of the cylinder, a sealing hole is opened on the conical seat for the push rod to pass through, a bracket is fixed to the upper end of the push rod, the bracket is fixedly connected to the material distribution seat, and a drive assembly capable of driving three threaded drills to rotate is installed inside the material distribution seat.

[0011] Preferably, the drive assembly includes a transmission cavity disposed within the material distribution seat, a second motor is fixedly mounted on the bracket, the output end of the second motor extends into the transmission cavity, and the lower end of the thread drill extends into the transmission cavity and is connected to the output end of the second motor via a gear set.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By installing a pair of hanging rails, a conveyor belt, and multiple threaded drills, the calcination box is placed at intervals on the pair of hanging rails. The conveyor belt drives multiple push plates to move, and the push plates push the calcination box to the position above the screen barrel. The cylinder is activated, and the push rod drives the material distribution seat to move upward. The second motor is started, and the gear set drives the three threaded drills to rotate. The three threaded drills drill into the block oxide in the middle and on both sides, breaking it down. The fragments fall into the screen barrel, which can continuously and automatically break down the block oxide in the calcination box.

[0014] 2. By installing a screen barrel, multiple crushing rods, and a guide cylinder cover, lumpy oxides fall into the screen barrel. The first motor is started, which drives the rotating drum to rotate through the pulley and belt, and then drives the screen barrel to rotate. The lumpy oxides slide down to both sides through the distribution seat and collide with the rotating multiple crushing rods, breaking them into smaller pieces. After multiple impacts, they are broken into granules and thrown out through the mesh, discharged through the guide cylinder cover, quickly completing the screening and mixing process with high efficiency.
