Description

Technical Field

[0001] The utility model relates to the technical field of lithium salt crushing equipment, in particular to a lithium salt crushing device. Background Technique

[0002] The ternary material is prepared by sintering using lithium salt and matrix as main materials. Among them, the lithium salt needs to be crushed into fine powder particles to fully contact and react with the matrix. During the sintering process, it is embedded in the NCM matrix structure. The consistency of the lithium salt and the size of the particles are particularly important.

[0003] At present, the lithium salt of the ternary material is pulverized by a jet mill. When the jet mill pulverizes the lithium salt, there are problems such as high energy consumption, large floor area, high noise, and poor particle size consistency. The processing cost per ton is high and it also affects the product indicators.

[0004] During the operation of the jet mill, the noise is loud, causing noise pollution to the production line personnel; the floor area is large, which is not conducive to equipment installation and increases the installation cost; due to the particle size being affected by air pressure during the crushing of the jet mill, the stability is poor, affecting the electrical properties of the ternary material. At the same time, considering the intensifying industry competition and to reduce the company's operating costs, it is necessary to develop a new type of lithium salt crushing equipment with a small floor area and low energy consumption. Therefore, it is particularly important to develop a new type of material pulverizing device. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above difficulties in the background technique and provide a lithium salt crushing device.

[0006] To achieve the above purpose, the technical solution adopted is: a lithium salt crushing device, including a main machine,

[0007] The main machine includes a feeding area, a crushing area and a discharging area that are communicated with each other;

[0008] The feeding area includes a feeding mechanism arranged at the top of the main machine;

[0009] The crushing area includes a feeding pipe and a crushing pipe. The feeding mechanism is arranged above the feeding pipe. The discharging area is arranged close to the crushing pipe. A stirring rod is arranged in the crushing area and penetrates through the feeding pipe and the crushing pipe and is arranged at the axis. A transmission dragon is arranged on the outer wall of the stirring rod in the feeding pipe and drives towards the crushing pipe. A plurality of stirring blades are arranged on the outer wall of the stirring rod in the crushing pipe. A plurality of zirconium beads are arranged in the crushing pipe;

[0010] A transmission mechanism is arranged on one side of the main machine close to the feeding pipe. The transmission mechanism drives the stirring rod in the crushing area to rotate circumferentially;

[0011] The discharging area includes a discharging pipe. A discharging screen is arranged at the connection end of the discharging pipe and the crushing pipe.

[0012] Further, the feeding mechanism is a feeding star valve provided above the material conveying pipe.

[0015] Further, the clamping device includes buckles correspondingly arranged on the outer wall of the outer sleeve far from the discharge sieve end and the outer wall of the stirring rod when the outer sleeve is sleeved on the stirring rod. Openings are formed in the buckles. After the outer sleeve and the stirring rod are clamped, a threaded mechanism is arranged in the openings for locking.

[0016] A snap ring is threadedly connected to the outer wall of the stirring rod close to the discharge sieve. An opening is formed in the snap ring. A buckle is also provided on the outer wall of the outer sleeve close to the discharge sieve end.

[0032] Embodiment Two

[0033] On the basis of Embodiment 1, the applicant found during the use of the device that after a long period of use during the grinding process of the lithium salt and the grinding medium zirconium beads, both the auger 9 and the stirring paddle 8 on the entire stirring rod 4 had a certain degree of wear. When replacing them subsequently, the entire stirring rod 4 needed to be removed from the device and replaced as a whole, resulting in a relatively high replacement cost. Regarding this problem, the applicant provided an outer sleeve 16 on the outer wall of the stirring rod 4. The outer wall of the stirring rod 4 is sleeved with an outer sleeve 16. The conveying auger 9 and the stirring paddle 8 are fixedly arranged on the outer sleeve 16. At both ends of the outer sleeve 16 and the stirring rod 4, there are clamping devices 12 to make them fixedly connected. The clamping device 12 includes a buckle 17 corresponding to the outer wall of the stirring rod 4 on the outer wall of the outer sleeve 16 at the end far from the discharge sieve 7 when the outer sleeve 16 is sleeved on the stirring rod 4. Openings 20 are provided on each of the buckles 17. After the outer sleeve 16 and the stirring rod 4 are clamped, a threaded mechanism is provided in the opening 20 for locking. The outer wall of the stirring rod 4 near the discharge sieve 7 is threadedly connected with a snap ring 19. Openings 20 are provided on the snap ring 19. A buckle 17 is also provided on the outer wall of the outer sleeve 16 at the end near the discharge sieve 7. This buckle 17 and the snap ring 19 are locked at the opening 20 of the snap ring 19 through a threaded mechanism.

[0034] As Figure 2-3 , after the applicant made this setting, the replacement cost of the entire stirring rod 4 is lower, and during subsequent overall cleaning of the stirring rod 4, it can be disassembled for cleaning, resulting in a better cleaning effect and higher overall practicality.

[0035] Embodiment 3

[0036] On the basis of Embodiment 1 and Embodiment 2, the applicant considered that a certain amount of heat would be generated during the crushing and grinding process of the main machine 1, and considered the service life problem of the main machine 1. As Figure 4 , the applicant sleeved an outer shell 5 on the pipe wall of the main machine 1 in the crushing area, and a water cooling circulation mechanism is provided between the outer shell 5 and the pipe wall of the crushing area. A sandwich layer 13 is provided between the outer shell 5 and the pipe wall of the crushing area. A water inlet 15 is provided at the top of the outer shell 5, and a water outlet 14 is provided at the bottom of the outer shell 5. During the use of the main machine 1, the entire interior of the main machine 1 can be cooled by water, making the operation of the main machine 1 more stable and increasing its service life.

[0037] During specific implementation, the applicant evenly provided a plurality of protrusions on the inner wall of the crushing pipe 6, and the height of the protrusions is 0.2 - 0.5 cm. The setting of these protrusions can make the friction and grinding effect between the stirring paddle 8 and the zirconium beads closer, improving the grinding rate.

[0038] Meanwhile, considering the anti-blocking problem of the discharge sieve 7, the outer wall of one end of the stirring rod 4 close to the discharge sieve 7 is detachably provided with an anti-blocking strip 18 arranged parallel to the discharge sieve 7. The distance between the anti-blocking strip 18 and the discharge sieve 7 is less than the diameter of a single zirconium bead, and the length of the anti-blocking strip 18 is 1-2 cm less than the diameter of the discharge sieve 7. After this setting, as the stirring rod 4 rotates, the anti-blocking strip 18 will scrape the surface of the entire discharge sieve 7 to prevent the ground lithium salt from being blocked at the discharge sieve 7 and affecting the overall grinding rate.
