Description

Technical Field

[0001] This utility model relates to the field of vanadium ore processing technology, and in particular to a cylindrical ammonium metavanadate grinding mechanism. Background Technology

[0002] As a key raw material for vanadium-nitrogen alloys and refined vanadium, ammonium metavanadate needs to be ground into powder and then mixed with other raw materials to form sintered spherical blanks. After being refined by a crusher, the ammonium metavanadate blocks are ground into powder by a grinder. Since some of the ammonium metavanadate combines with water of crystallization to form hydrated ammonium metavanadate, some of the water of crystallization decomposes when heated during the grinding process. Therefore, during the grinding of ammonium metavanadate, the powder material will stick together due to the presence of water, which affects the grinding efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention proposes a highly efficient ammonium metavanadate grinding mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cylindrical ammonium metavanadate grinding mechanism, characterized in that it includes a horizontally arranged cylinder and a rotating shaft rotatably connected inside the cylinder. Two annular mounting frames are fixedly arranged on the rotating shaft, respectively located at both ends of the cylinder. A plurality of grinding rollers are rotatably connected between the two annular mounting frames. Scrapers fixed on the annular mounting frames are arranged between adjacent grinding rollers, and the scrapers abut against the inner wall of the cylinder. A detachable discharge gate is provided at the bottom of the cylinder. A feed hopper is also provided on the cylinder.

[0005] Furthermore, several partitions are fixedly installed on the annular mounting frame, and the partitions are located inside the annular mounting frame.

[0006] The crushing roller can crush and refine the material at the bottom of the cylinder during the rotation of the shaft, while the scraper can effectively scrape off the material adhering to the inner wall of the cylinder. The presence of the baffle allows the material to be lifted to a certain height and then fall to the top of the cylinder, forming an efficient tumbling of the material. The process of falling material is also a process of cleaning the material adhering to the crushing roller, the ring mounting frame and other components, as well as a process of material collision with each other, which improves the refining efficiency. Compared with the method of crushing and grinding materials by two rollers, the defects of uneven crushing and low crushing efficiency caused by the long-term adhesion of water-containing materials are effectively improved.

[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0010] like Figure 1 As shown, the grinding mechanism includes a horizontally arranged material cylinder 1 and a rotating shaft 2 rotatably connected inside the material cylinder 1. Two annular mounting frames 3 are fixedly mounted on the rotating shaft 2, located at both ends of the material cylinder 1. Several grinding rollers 4 are rotatably connected between the two annular mounting frames 3. Scrapers 8 are fixed on the annular mounting frames 3 between adjacent grinding rollers 4 and abut against the inner wall of the material cylinder 1. A detachable discharge gate 5 is provided at the bottom of the material cylinder 1. A feed hopper 6 is also provided on the material cylinder 1. Several partitions 7 are also fixedly mounted on the annular mounting frames 3 and are located inside the annular mounting frames 3. The scrapers 8 and the partitions 7 are an integral structure.

[0011] The crushing roller 4 can crush and refine the material at the bottom of the cylinder 1 during the rotation of the rotating shaft 2, while the scraper 8 can effectively scrape off the material adhering to the inner wall of the cylinder 1. The presence of the partition 7 allows the material to be lifted to a certain height and then fall to the top of the cylinder 1, forming an efficient tumbling of the material. The process of falling material is also a process of cleaning the material adhering to the crushing roller 4, the annular mounting frame 3 and other components, as well as a process of material collision with each other, which improves the refining efficiency. Compared with the method of crushing and grinding materials by double rollers, the defects of uneven crushing and low crushing efficiency caused by long-term adhesion of water-containing materials are effectively improved.

[0012] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
