Description

Technical Field

[0001] The invention belongs to the technical field of vanadium ore processing and relates to a high-purity vanadium roasting and vanadium ball making device. Background Art

[0002] High-purity vanadium is produced by baking ammonium metavanadate. Currently, most of the methods used are to make balls, place them in crucibles, and then send them into baking kilns. The vanadium balls are formed by molds and have a multi-faceted structure to form ventilation gaps in the crucible, which is conducive to the balance of heating and reaction conditions. When using a rotary kiln for baking vanadium, the vanadium balls need to roll during the dehydration stage and are not easy to fall apart. Therefore, the existing vanadium ball design and ball-making method are not applicable. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-purity vanadium roasting vanadium ball making device to address the above-mentioned problems existing in the existing technology. The technical problem to be solved by the present invention is how to quickly fill the balls with ammonium metavanadate mud.

[0004] The objectives of the present invention can be achieved through the following technical solutions: a high-purity vanadium roasting vanadium ball making device, characterized in that it includes a lifting tube, a lifting auger rotatably connected to the lifting tube, a feed hopper located outside the lifting tube and a mold hopper located at the lower end of the lifting tube, the mold fed into the mold hopper is a hollow filler ball, the hollow filler ball includes a hollow spherical body, the spherical body has a plurality of material holes connected to the inner cavity of the spherical body; the inner wall of the lifting tube is evenly distributed with a plurality of longitudinally arranged ribs, the lifting auger is driven to rotate by a motor, the lower end of the lifting tube has a mold inlet connecting the inner cavity of the lifting tube and the mold hopper, the tube wall in the middle and lower part of the lifting tube has a feed inlet connecting the inner cavity of the lifting tube and the feed hopper, and the feed inlet is located above the mold inlet.

[0005] Furthermore, the feeding hole is in the shape of a strip arranged longitudinally on the wall of the lifting pipe.

[0006] Furthermore, the upper end of the lifting pipe is provided with a ball outlet pipe.

[0007] Furthermore, a partition net is provided at the feed hole.

[0008] Add the humidified ammonium metavanadate mud to the feeding hopper. Place the cleaned hollow packing balls into the die hopper. The motor drives the lifting auger to rotate. The ammonium metavanadate mud has an upward trend. Under the restricting action of the ribs, the hollow packing balls also have an upward trend. During this process, the hollow packing balls roll upward, and the mud enters the inner holes of the hollow packing balls. Under the action of the pipe wall of the lifting pipe above the feeding port, the adhering material outside the hollow packing balls can be scraped off. In addition, since the hollow packing balls are in a rolling state during the lifting process, the mud can be in a relatively compact state inside the hollow packing balls. This method of filling the balls has a simple structure, and there is less adhesion on the surface of the hollow packing balls after loading the balls, and it can be directly used as the vanadium roasting material for the rotary kiln.

[0012] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0013] As Figure 1 and Figure 2 shown in the high-purity vanadium roasting and ball-making device, which includes a lifting pipe 1, a lifting auger 2 rotatably connected inside the lifting pipe 1, a feeding hopper 4 located outside the lifting pipe 1, and a die hopper 3 located at the lower end of the lifting pipe 1. The mold fed into the die hopper 3 is a hollow packing ball 5. The hollow packing ball 5 includes a hollow spherical body, and the spherical body is provided with a plurality of material holes communicating with the inner cavity of the spherical body; a plurality of longitudinally arranged ribs 6 are uniformly distributed circumferentially on the inner wall of the lifting pipe 1. The lifting auger 2 is driven by a motor to rotate. The lower end of the lifting pipe 1 has a die inlet communicating the inner cavity of the lifting pipe 1 with the die hopper 3. The pipe wall in the middle and lower part of the lifting pipe 1 has a feeding port communicating the inner cavity of the lifting pipe 1 and the feeding hopper 4, and the feeding port is located above the die inlet.

[0014] The feeding holes are in the form of strips longitudinally arranged on the pipe wall of the lifting pipe 1. The upper end of the lifting pipe 1 has a ball outlet pipe 7, and a partition net is arranged at the feeding hole.

[0015] Wetted ammonium metavanadate sludge is added from the feed hopper 4, and the cleaned hollow filler balls 5 are placed in the mold hopper 3. The motor drives the lifting auger 2 to rotate, and the ammonium metavanadate sludge has an upward trend. Under the restrictive effect of the ribs 6, the hollow filler balls 5 also have an upward trend. During this process, the hollow filler balls 5 roll upward, and the sludge enters the inner hole of the hollow filler balls 5. Under the action of the wall of the lifting pipe 1 above the feed port, the adhered material outside the hollow filler balls 5 can be scraped off. In addition, because the hollow filler balls 5 are in a rolling state during the lifting process, the sludge can be in a relatively compact state inside the hollow filler balls 5. This ball filling method has a simple structure, and the surface of the hollow filler balls 5 after filling has less adherence, so it can be directly used as vanadium baking material in the rotary kiln.

[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
