Abstract
Description
Technical Field
[0001] This utility model belongs to the field of praseodymium-neodymium fluoride production technology, specifically relating to a pulverizer with a circulating filtration function for praseodymium-neodymium fluoride production. Background Technology
[0002] Praseodymium-neodymium fluoride is an important rare earth functional material. Its background technology originates from the in-depth development and application of rare earth elements. Its development process has gone through the progress of rare earth separation and purification technology to the innovation of fluoride synthesis process. In application scenarios, it is mainly used as a catalyst, laser material, magnetic material, etc., and plays a key role in petrochemical, optical fiber communication, aerospace and other fields, promoting the technological progress and industrial upgrading of related industries.
[0003] Application No. 202322091836.4 discloses a pulverizer for the production of praseodymium oxalate. The utility model discloses a pulverizer for praseodymium oxalate production, including a housing. Through the coordinated use of a feed hopper, grinding cylinder, rotating rod, drive motor, grinding cone, and grinding bucket, it effectively grinds and pulverizes praseodymium oxalate. Through-holes allow the ground praseodymium oxalate to fall into the housing. A sieve plate further enhances the pulverization of the praseodymium oxalate. The screening process utilizes a vibrator to shake the screen plate, improving screening efficiency. The conical guide hopper and discharge pipe work together to facilitate the discharge of fine praseodymium oxalate from the discharge pipe. The discharge hopper also allows insufficiently ground praseodymium oxalate to be discharged and collected for further grinding, ensuring thorough grinding and improving the yield of subsequent praseodymium fluoride.
[0004] The pulverizer system described in the above document, although capable of preliminary grinding of raw materials and realizing basic pulverization function, has certain limitations. The system fails to perform multiple processing of raw materials, which may result in some raw materials not achieving optimal fineness and uniformity. In order to further improve the processing effect of raw materials and product quality, it is necessary to consider increasing the number of times the raw materials are circulated to ensure that all raw materials can be repeatedly ground to achieve higher processing standards and better material properties. Therefore, a pulverizer with circulating filtration function for the production of praseodymium-neodymium fluoride has emerged. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example
[0027] Reference Figures 1-4 This embodiment of the present invention provides a pulverizer with a circulating filtration function for the production of praseodymium-neodymium fluoride, comprising:
[0028] The crushing mechanism 100 includes a mounting frame 101, a crushing motor 102 adapted to be installed on the side wall of the mounting frame 101, and a grinding assembly 103 disposed on the side wall of the mounting frame 101.
[0029] The powder screening mechanism 200 includes a connecting shell 201, a sorting shell 202 connected to the bottom of the connecting shell 201, reserved slots 203 on both sides of the sorting shell 202, a partition 204 fixedly installed on the inner wall of the sorting shell 202, a baffle 205 hinged to the side wall of the partition 204, a circulating hopper 206 fixedly installed on one side of the partition 204, a feeding hopper 207 fixedly installed on the other side of the partition 204, a screening component 208 disposed in the inner cavity of the sorting shell 202, and a lifting component 209 disposed at the bottom of the sorting shell 202.
[0030] Specifically, the grinding assembly 103 includes a feed hopper 103a, a gate plate slidably mounted on the side wall of the feed hopper 103a, a transfer hopper 103c disposed below the feed hopper 103a, and a grinding shell 103d connected to the side wall of the transfer hopper 103c. The grinding assembly 103 also includes a cover plate 103e hinged to the side wall of the grinding shell 103d, a buckle 103f fixedly mounted on the side wall of the cover plate 103e, a grinding shaft 103g adapted to be mounted on the inner wall of the grinding shell 103d, and a grinding plate 103h movably connected to the side wall of the grinding shaft 103g.
[0031] Furthermore, the grinding shaft 103g has a cutting head on its side wall, and the grinding plate 103h has a gap on its side wall. When used with the cutting head, the raw material can be crushed and discharged through the gap. The hinged cover plate 103e and the buckle 103f make it easy to open the grinding shell 103d and facilitate the cleaning of the device.
[0032] The screening assembly 208 includes a sieve 208a slidably mounted on the inner wall of the reserved groove 203, an opening 208b provided on the side wall of the sieve 208a, and a connecting plate 208c fixedly mounted on the side wall of the sieve 208a. The screening assembly 208 also includes a connecting seat 208d fixedly mounted on the side wall of the connecting plate 208c, and an eccentric shaft disk 208e connected to the side wall of the connecting seat 208d by a bearing. The screening assembly 208 also includes a screening motor 208f adapted to be mounted on the side wall of the connecting plate 208c, a cylinder 208g adapted to be mounted on the side wall of the connecting plate 208c, and a push plate 208h fixedly mounted on the end of the cylinder 208g.
[0033] Preferably, the output end of the motor is fixedly connected to the eccentric shaft disk 208e. When the motor drives the eccentric shaft disk 208e to rotate, it will drive the connecting seat 208d to move back and forth, thereby driving the sieve 208a to move back and forth, improving the filtration efficiency.
[0034] The lifting assembly 209 includes a connecting pipe 209a connected to the bottom of the circulating hopper 206, a stacking box 209b connected to the end of the connecting pipe 209a, an auger 209c adapted to be installed on the inner wall of the stacking box 209b, a lifting pipe 209d sleeved on the side wall of the auger 209c, and a discharge pipe 209e connected to the side wall of the lifting pipe 209d.
[0035] It should be noted that the auger 209c, together with the lifting pipe 209d, can lift the raw material and discharge it through the discharge pipe 209e connected to the side wall of the lifting pipe 209d. The discharge pipe 209e is located above the transfer bucket 103c, which facilitates the secondary processing of raw materials that do not meet the standards.
[0036] In operation, raw materials are added through the feed hopper 103a, and the feeding speed is controlled by the opening and closing of the gate. This, combined with the transfer hopper 103c, ensures the quantity of raw materials processed each time. After entering the grinding shell 103d through the transfer hopper 103c, the grinding motor drives the grinding shaft 103g to rotate. The cutters on the side wall of the grinding shaft 103g crush the raw materials in the grinding shell 103d. This, combined with the grinding plates 103h, improves the crushing efficiency. After crushing, the raw materials are discharged through the gaps between the grinding plates 103h. The discharged fragments fall into the sorting shell 202 through the connecting shell 201. Through the partition 204, the fragments are concentrated on one side of the partition 204. The screening motor 208f operates, driving the eccentric shaft disc 208e. Rotation causes the eccentric shaft disc 208e to move the connecting seat 208d back and forth, thereby causing the screen 208a to move back and forth rapidly. Raw materials that meet the standards fall into the discharge hopper 207 through the screen 208a and are transferred through the discharge hopper 207. Unqualified raw materials remain on the screen 208a. The cylinder 208g operates, pushing the push plate 208h forward. The raw materials push through the baffle 205 hinged to the partition plate 204 and fall into the circulation hopper 206 through the opening 208b. They then enter the stacking box 209b through the connecting pipe 209a. The auger 209c operates, working in conjunction with the lifting pipe 209d to move the raw materials upward and discharge them through the discharge pipe 209e, falling into the transfer hopper 103c for further processing.
[0037] In summary, the cooperation of the feed hopper 103a, gate, and transfer hopper 103c ensures the uniformity of raw material input and the accuracy of the quantity processed each time, providing a stable foundation for the subsequent crushing process. The combined action of the grinding shaft 103g driven by the grinding motor and its side wall cutters with the grinding plate 103h significantly improves the crushing efficiency and fineness of the raw materials. The partition 204 and screening component 208 in the sorting shell 202 ensure the effective separation of the crushed raw materials, allowing qualified raw materials to quickly fall into the discharge hopper 207, while unqualified raw materials are recycled back into the processing flow through the circulation system. This not only improves the utilization rate of raw materials but also reduces waste generation, realizing the recycling of resources. The design of the auger 209c and lifting pipe 209d in the lifting component 209 allows unqualified raw materials to smoothly return to the transfer hopper 103c for reprocessing. The entire system forms a closed loop, greatly improving the degree of production automation and overall operating efficiency, reducing operating costs, and enhancing the practicality and economy of the equipment.
