Description

Technical Field

[0001] The utility model relates to the technical field of lithium sulfate solution production, in particular to an ore crusher for lithium sulfate solution production. Background Art

[0002] Lithium sulfate is a chemical with the molecular formula Li2SO4. It appears as colorless monoclinic crystals or white crystalline powder. It is soluble in water but insoluble in acetone and anhydrous ethanol. During its preparation, lithium carbonate solution is added to a reactor, and sulfuric acid is slowly added under stirring to react. After evaporation and concentration, cooling and crystallization, centrifugation, lithium sulfate monohydrate is obtained, and lithium sulfate is obtained after drying. Lithium carbonate is prepared by mixing spodumene concentrate and limestone in a certain weight ratio, grinding them together, sintering them at 1150-1250℃ to produce lithium aluminate and calcium silicate, and then pulverizing them through wet grinding. Lithium hydroxide is leached with washing liquid, filtered through sedimentation, and the residue is returned or washed to remove the residue. The leachate is evaporated and concentrated, and then sodium carbonate is added to produce lithium carbonate. After centrifugation and drying, the finished lithium carbonate product is obtained. However, during the use of existing ore crushers, There are still some problems, such as an ore crusher with publication number CN218222594U. The ore enters the shell through the feed hopper. Under the drive of the crushing drive device, the two crushing rollers crush the ore. At the same time, water is sprayed between the two crushing rollers through the first nozzle, which reduces the generation of dust. The incompletely crushed ore is circulated to the feed hopper through the conveying device and crushed again. The ore is circulated and crushed by the conveying device. However, when adding materials during the crushing process, due to the lack of necessary protective measures above the feeding port, the fragmentation and splashing of the ore will make the feeding process have certain risks. At the same time, a large amount of ore accumulates at the feeding port during the crushing process, which can easily cause ore accumulation, making it impossible for the ore to fall under the action of gravity, affecting the normal use of the crusher.

The upper end of the outer box body 1 is provided with a shaking mechanism, which realizes slow feeding through vibration during the crushing process while preventing ore accumulation and blockage;

[0034] The material shaking mechanism includes: a feed box 6, which is slidably mounted on the upper end of the outer box body 1, and a feed port 7 is provided on the outer surface of one side of the feed box 6, a feeding channel 8 is fixedly provided on the upper end of the outer box body 1 on the side where the feed port 7 is provided, and a contact rod 10 is fixedly connected to the lower end surface of one side of the feed box 6, and a rotating contact wheel 9 is installed on the side surface of the connecting gear 4;

[0035] The two connecting gears 4 are meshed with each other, and the outer surface of one side of the feed box 6 with the feed port 7 is in contact with the side surface of the feeding channel 8, and the lower end opening of the feeding channel 8 is staggered with the feed port 7, and the contact wheel 9 and the connecting gear 4 are eccentrically arranged;

[0036] During crushing, the drive motor 5 on the side surface of the outer box body 1 is started, and the drive motor 5 drives the first crushing wheel 2 and the second crushing wheel 3 to rotate in opposite directions through two mutually meshing connecting gears 4. At this time, enough crushed ore is put into the feeding channel 8. When the contact wheel 9 on the surface of the gear 4 at one end of the second crushing wheel 3 is connected to the lower end of the contact rod 10 during rotation, the contact rod 10 drives the feed box 6 to slide up so that the feed port 7 coincides with the lower end opening of the feeding channel 8. At this time, the ore in the feeding channel 8 enters the feed box 6 through the feed port 7, and the ore in the feed box 6 falls between the rotating first crushing wheel 2 and the second crushing wheel 3 and is crushed. At the same time, the feed box 6 will not cause the ore to accumulate and be unable to fall during the up and down reciprocating sliding process. Example
