Technical Field
[0001] This utility model relates to the field of rare earth production technology, and in particular to a filter box device for rare earth production. Background Technology
[0002] Rare earth elements are commonly used additives and are now widely used in the manufacture of materials in various fields, serving as key elements for the development of high-tech industries. However, my country's rare earth mineral reserves are not abundant, and their widespread use has led to a shortage of rare earth resources.
[0003] In the rare earth processing flow, after the material is dissolved by acid, it needs to be filtered and precipitated in a vacuum filter box. Through continuous washing and rinsing, the rare earth elements are dissolved in the water and carried away by the pumped water to the next step of rare earth element extraction. However, in the actual precipitation and separation process of rare earth production, some fine-grained rare earth elements form rare earth oxides, such as yttrium (Y), lutetium (Lu), and ytterbium (Yb). Due to their own agglomeration characteristics, they tend to aggregate in the middle of the filter cloth in the vacuum filter box. The finer the particles, the more obvious the agglomeration trend. Therefore, it is difficult to completely filter the solid-liquid mixture containing rare earth raw materials, resulting in incomplete filtration of rare earth elements and waste of rare earth resources.
[0004] Currently, in actual production, a solution of continuous washing and rinsing for more than 8 hours is adopted. This method achieves complete filtration by increasing the number of filtrations and the filtration time, which wastes human resources and greatly reduces production efficiency. Summary of the Invention
[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a filtration box device for rare earth production, thereby increasing the output of rare earth products, avoiding the waste of rare earth resources, and improving production efficiency.
[0006] The purpose of this utility model is achieved as follows:

[0008] A stirring assembly is provided at the upper end of the stirring tank.

The centers of the upper connecting shaft and the lower connecting shaft are connected to the long stirring shaft. Two side stirring rods are connected to both ends of the upper connecting shaft. A middle stirring rod is provided between the side stirring rods and the long stirring shaft. A set of middle stirring rods and side stirring rods are symmetrically provided on the left and right sides of the long stirring shaft.
[0009] An ultrasonic generator is fixedly installed on one side of the inner wall of the separation box, and a collection tank is snapped onto the outside of the separation box.
[0010] Furthermore, a connecting spring is fixedly installed between the connecting frame and the separation box.
[0011] Furthermore, an electric telescopic rod is fixedly installed on the inner wall of both ends of the separation box, and a push plate is fixedly installed on one side of the electric telescopic rod.
[0012] Furthermore, the length of the stirring side rod is less than the length of the stirring center rod, and the length of the stirring center rod is less than the length of the stirring long axis, forming a symmetrical centralized stirring assembly.
[0013] Furthermore, a connecting assembly is provided at the bottom of the stirring shaft. The connecting assembly includes a fixing frame, and a rotary motor is fixedly mounted on the upper end of the fixing frame.

The sliding grooves are slidably connected to the limiting plate through a connecting block.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention provides a filtration box device for rare earth production. By setting up a symmetrical centralized stirring assembly, filtration is performed while stirring, preventing fine rare earth oxides from accumulating in the middle of the filtration box. At the same time, the ultrasonic waves generated by the ultrasonic generator can produce strong vibration and cavitation in the solution, causing the agglomerated fine rare earth oxide particles to disperse under high-frequency vibration and impact. The filter plate can intercept and collect the incompletely reacted rare earth oxide particles in the collection tank, realizing resource recycling and reuse, avoiding waste of raw materials, and further improving the utilization rate of rare earths and product output.

[0025] Electric telescopic rods 47 are fixedly installed on the inner walls of both ends of the separation box 2, and a push plate 48 is fixedly installed on one side of the electric telescopic rods 47. Furthermore, by installing electric telescopic rods 47, the electric telescopic rods 47 drive the push plate 48 to move, thereby pushing the push plate 48 to gather solids, making the device more widely applicable.
[0026] The mixing tank 1 is provided with a mixing assembly 3 at the upper end. The mixing assembly 3 includes a long mixing shaft 32, an upper connecting shaft 33, a lower connecting shaft 34, a middle mixing rod 35, and a side mixing rod 36. The top end of the long mixing shaft 32 extends out of the mixing tank 1 and is connected to one side of the servo motor 31 for transmission. The upper connecting shaft 33 and the lower connecting shaft 34 are vertically connected to the upper and middle parts of the long mixing shaft 32, respectively. The centers of the upper connecting shaft 33 and the lower connecting shaft 34 are connected to the long mixing shaft 32.
[0027] Two stirring rods 36 are respectively connected to both ends of the upper connecting shaft 33. The top end of the stirring rod 36 is fixed to the upper connecting shaft 33, and the lower part of the stirring rod 36 is connected to the lower connecting shaft 34. A stirring middle rod 35 is provided between the stirring rod 36 and the stirring long shaft 32. The top end of the stirring middle rod 35 is fixed to the upper connecting shaft 33, and the middle part of the stirring middle rod 35 is connected to the lower connecting shaft 34.
[0028] The length of the stirring side rod 36 is less than the length of the stirring middle rod 35, and the length of the stirring middle rod 35 is less than the length of the stirring long shaft 32. A set of stirring middle rods 35 and stirring side rods 36 are symmetrically arranged on the left and right sides of the stirring long shaft 32 to form a symmetrical centralized stirring assembly, which prevents fine-grained rare earth oxides from agglomerating in the center of the stirring box 1 during the stirring process.

[0032] In this embodiment 1, the ultrasonic waves 49 generated by the ultrasonic generator can produce strong vibrations and cavitation in the solution, causing the agglomerated fine rare earth oxide particles to be dispersed by high-frequency vibrations and impacts, thus enhancing the practicality of the device and expanding its application range.
[0033] Working principle:
[0034] This utility model provides a filtration box device for rare earth production. In use, materials are first added to a mixing tank 1, and a servo motor 31 drives the long stirring shaft 32 to rotate, which in turn drives the stirring rod 33 to stir the materials, improving the stirring effect. Next, a rotary motor 52 drives a limiting plate 53 to rotate along a sliding groove 55, exposing a through hole 56 on a fixing plate 54, allowing the material stored in the mixing tank 1 to fall into a separation tank 2. A filter plate 41, in conjunction with an ultrasonic generator 49, enables liquid-solid separation. A connecting spring 411 at the bottom of the filter plate 41 continuously vibrates up and down, enhancing the separation effect. An electric telescopic rod 47 pushes a pusher plate 48 to collect solids. Then, a drive motor 42 drives a lead screw 43 to rotate, causing a threaded cleaning plate 46 to move along the lead screw 43, pushing the solids into a collection trough 412 for easy collection. The liquid flows to the bottom of the separation tank 2 and is recovered through the outlet. This enhances the practicality of the device and broadens its application range.
