[0004] However, the above device still has shortcomings:

[0005] When the slurrying operation is being carried out, the raw material particles are relatively large and it is not easy for the slurrying reaction to occur. The reaction speed can be increased by stirring, but there will still be a small amount of raw materials with large particles that will not be slurried. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a mixing device for lithium carbonate slurrying, which solves the problem that when the raw material particles are large and it is not easy to undergo slurrying reaction, stirring can increase the reaction speed, but a small amount of raw material with large particles will not be slurried.

[0007] To achieve the above object, the utility model proposes a mixing device for lithium carbonate slurrying, comprising a slurrying barrel, a through hole is opened on the top of the slurrying barrel, a stirring rod is rotatably connected inside the slurrying barrel, and a crushing assembly is arranged inside the slurrying barrel, wherein:

[0008] The crushing assembly includes a driving gear, which is fixedly connected to the side wall of the stirring rod, and the driving gear is arranged on the inner side wall of the top of the slurrying barrel. A transmission gear and a rotating gear are rotatably connected to the inner side wall of the top of the slurrying barrel.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the setting of the crushing component, when the slurrying operation is carried out, the stirring rod rotates under the drive of the motor, and the transmission gear meshing with the driving gear rotates, and the rotating gear also rotates at this time. The crushing and cutting effect of the cutting knife can be completed by the rotation of the stirring rod. The faster the stirring rod rotates, the faster the cutting knife cuts.

[0016] The advantage of this design is that when the slurrying operation is carried out, the cutting operation can be completed without the need for an additional power source. When the lithium carbonate particles are added quickly, the stirring speed of the device will be faster, and the cutting speed of the crushing component will be faster. When the lithium carbonate particles are added slowly, the stirring speed will also slow down. This operation can not only turn the lithium carbonate particles into smaller particles, thereby improving the efficiency of slurrying, but also improve energy utilization.

[0017] 2. Through the setting of the vibration component, when the crushing operation is carried out, the rotating gear rotates. Due to the instability of the spring, this will cause the rotating gear to vibrate when rotating. The lithium carbonate particle powder on the cutting knife can be shaken off by vibration, thereby achieving the effect of cleaning the cutting knife. Secondly, vibration can also prevent the lithium carbonate particles from clogging the channel in the rotating gear.

[0018] 3. Through the setting of scrapers and brushes, after the slurrying operation is completed, the motor can continue to run for a period of time. The stirring rod will pass through a pair of scrapers, and the brushes on the pair of scrapers will clean the stirring rod. The self-cleaning can reduce the workload of the staff.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-3As shown, a mixing device for lithium carbonate slurrying includes a slurrying barrel 1, a through hole 11 is opened on the top of the slurrying barrel 1, a stirring rod 21 is rotatably connected inside the slurrying barrel 1, and a crushing assembly 5 is arranged inside the slurrying barrel 1, wherein:

[0025] The crushing assembly 5 includes a driving gear 51, which is fixedly connected to the side wall of the stirring rod 21. The driving gear 51 is arranged on the inner side wall of the top of the slurrying barrel 1. A transmission gear 52 and a rotating gear 54 are rotatably connected to the inner side wall of the top of the slurrying barrel 1. A fixing nut 53 is threadedly connected to the side wall of the transmission gear 52. The transmission gear 52 and the driving gear 51 are meshed with each other. The transmission gear 52 and the rotating gear 54 are meshed with each other. A plurality of cutting knives 55 are fixedly connected to the inside of the rotating gear 54.

[0026] A motor 2 is arranged on the top of the slurry barrel 1, and a stirring rod 21 is fixedly connected to the bottom of the motor 2. The bottom of the stirring rod 21 passes through the top of the slurry barrel 1 and extends into the interior of the slurry barrel 1. The stirring rod 21 extends to the side wall inside the slurry barrel 1 and is fixedly connected to a plurality of stirring rods 22.

[0027] When the slurrying operation is performed, the stirring rod 21 rotates under the drive of the motor 2, and the transmission gear 52 that is engaged with the driving gear 51 rotates. At this time, the rotating gear 54 also rotates. The crushing and cutting effect of the cutting knife 55 can be achieved through the rotation of the stirring rod 21. The faster the stirring rod 21 rotates, the faster the cutting knife 55 cuts.

[0028] When the slurrying operation is performed, the cutting operation can be completed without the need for an additional power source. When the lithium carbonate particles are added at a faster speed, the stirring speed of the device is faster, and the cutting speed of the crushing component 5 is also faster. When the lithium carbonate particles are added at a slower speed, the stirring speed will also be slower. This operation can not only turn the lithium carbonate particles into smaller particles, thereby improving the efficiency of slurrying, but also improve the utilization rate of energy.

[0029] A vibration assembly 6 is arranged on the inner wall of the top of the slurry barrel 1, and the vibration assembly 6 includes an annular groove 61, which is opened on the inner wall of the top of the slurry barrel 1, and a ring block 62 is rotatably connected inside the annular groove 61, and a spring 63 is fixedly connected to the side wall of the ring block 62, one end of the spring 63 is fixedly connected to the ring block 62, and the other end of the spring 63 is fixedly connected to a ring plate 64, the ring plate 64 is slidably connected in the annular groove 61, and the rotating gear 54 is fixedly connected to the bottom of the ring plate 64.

[0030] When the crushing operation is performed, the rotating gear 54 rotates. Since the spring 63 is unstable, the rotating gear 54 will vibrate when rotating. The lithium carbonate particle powder on the cutting knife 55 can be shaken off by the vibration, thereby achieving the effect of cleaning the cutting knife 55. Secondly, the vibration can also prevent the lithium carbonate particles from clogging the channel in the rotating gear 54.

[0031] A through hole 11 is formed on the upper surface of the slurry barrel 1 , and an annular groove 61 is arranged around the through hole 11 . A feeding port 3 is fixedly connected to the top of the slurry barrel 1 , and the feeding port 3 is arranged above the through hole 11 .

[0032] A pair of scrapers 4 are fixedly connected to the inner side wall of the slurry barrel 1 , a brush 41 is fixedly connected to the side wall of the scraper 4 , and the stirring rod 22 is arranged between the pair of scrapers 4 .

[0033] After completing the slurrying operation, the motor 2 can continue to run for a period of time. The stirring rod 22 will pass through a pair of scrapers 4, and the brush 41 on the pair of scrapers 4 will clean the stirring rod 22. The self-cleaning can reduce the workload of the staff.

[0034] Working principle: When performing the slurrying operation, lithium carbonate is poured into the slurrying barrel 1 through the feeding port 3, and then the motor 2 is turned on. The stirring rod 21 rotates under the drive of the motor 2, and the transmission gear 52 that is engaged with the driving gear 51 rotates through the rotation of the stirring rod 21. At this time, the rotating gear 54 also rotates. The crushing and cutting effect of the cutting knife 55 can be achieved through the rotation of the stirring rod 21. The faster the stirring rod 21 rotates, the faster the cutting speed of the cutting knife 55 is.

[0035] When the crushing operation is performed, the rotating gear 54 rotates. Since the spring 63 is unstable, the rotating gear 54 will vibrate when rotating. The lithium carbonate particle powder on the cutting knife 55 can be shaken off by the vibration, thereby achieving the effect of cleaning the cutting knife 55. Secondly, the vibration can also prevent the lithium carbonate particles from clogging the channel in the rotating gear 54.

[0036] After completing the slurrying operation, the motor 2 can continue to run for a period of time. The stirring rod 22 will pass through a pair of scrapers 4, and the brush 41 on the pair of scrapers 4 will clean the stirring rod 22. The self-cleaning can reduce the workload of the staff.

[0037] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
