Their easy pulverization characteristics often lead to agglomeration, which significantly increases the difficulty of weighing and feeding the raw materials, and is also prone to clogging the feeding port.

[0003] Usually, the core raw materials of the ternary precursor need to be crushed before unloading. For example, the Chinese utility model with application number: CN201921992412.2 is named: A crushing and processing device for single-crystal ternary positive electrode materials, including a jaw crusher and a multi-stage continuous roller machine. The jaw crusher has a first feed port and a first discharge port.

At the same time, during the crushing, screening and automatic weighing process, a negative pressure fan 61 and an absorption tower 62 are used to remove fine powder and dust to avoid the flying of fine powder.

[0020] It should be noted that the ternary precursor raw material crushing device and feeding system of the present invention are used for but not limited to the field of material processing technology. For the convenience of explanation, in the present invention, only the application of the ternary precursor raw material crushing device and feeding system in the field of material processing technology is used as an example for explanation. The principles of the application of the ternary precursor raw material crushing device and feeding system in other types of equipment are essentially the same as those applied in the field of material processing technology, and will not be repeated here.

[0021] See also Figures 1 to 6 , Figure 11 is a schematic structural diagram of a ternary precursor raw material crushing device and a feeding system in an embodiment of the present invention. The ternary precursor raw material crushing device is connected to a reactor 1, which is used to produce a ternary precursor and includes a shell 2, a crushing component 3, a screening component 4, a weighing component 5 and a dust removal component 6. The shell 2 is hollow inside and is provided with a feed port 21 and a discharge port 22. The discharge port 22 is connected to the interior of the reactor 1. The crushing component 3 is built into the shell 2 and is arranged relative to the feed port 21. The screening component 4 is arranged below the discharge end of the crushing component 3. The weighing component 5 is movably arranged in the shell 2 relative to the discharge end of the screening component 4 and can slide close to or away from the discharge port 22 for quantitatively feeding materials into the discharge port 22. The dust removal component 6 includes a negative pressure fan 61 and an absorption tower 62. The negative pressure fan 61 is built into the shell 2, and the air inlet end of the absorption tower 62 is connected to the air outlet end of the negative pressure fan 61.

[0022] In this device, a crushing component 3, a screening component 4 and a weighing component 5 are arranged inside the shell 2. The crushing component 3 is arranged relative to the feed port 21, and is used to crush the compacted raw materials. The screening component 4 is arranged below the discharge end of the crushing component 3, and is used to screen the materials. The weighing component 5 is arranged relative to the discharge end of the screening component 4, and can slide close to or away from the discharge port 22, and quantitatively feed the materials into the discharge port 22.

At the same time, during the crushing, screening and automatic weighing process, the negative pressure fan 61 and the absorption tower 62 are used to remove fine powder and dust to avoid the flying of fine powder. This can solve the technical problem in the prior art that the raw material crushing and the raw material unloading are two separate processes, which makes it easy to cause the flying of fine powder when transporting the crushed powder material, thereby polluting the working environment.

[0024] Furthermore, the negative pressure fan 61 and the absorption tower 62 here are both common and easy-to-purchase equipment on the market.

[0054] Furthermore, the control component 8 here is a PLC control circuit that is common and easy to purchase on the market, which belongs to a conventional setting well known to those skilled in the art and will not be described in detail.

[0055] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the present invention is described in detail: The shell 2 is provided with a crushing component 3, a screening component 4 and a weighing component 5. The crushing component 3 is arranged relative to the feed port 21 and is used to crush the compacted raw materials. The screening component 4 is arranged below the discharge end of the crushing component 3 and is used to screen the materials. The weighing component 5 is arranged relative to the discharge end of the screening component 4 and can slide close to or away from the discharge port 22 and quantitatively feed the materials into the discharge port 22. The negative pressure fan 61 is built into the shell 2, and the air inlet end of the absorption tower 62 is connected to the air outlet end of the negative pressure fan 61. Compared with the prior art, the compacted raw materials are crushed, screened and automatically weighed by the crushing component 3, the screening component 4 and the weighing component 5 arranged in sequence, and the quantitative materials are fed into the reactor 1 through the discharge port 22. At the same time, the negative pressure fan 61 and the absorption tower 62 are used to remove fine powder and dust during the crushing, screening and automatic weighing process to avoid the flying of fine powder.

[0056] The specific working process of the present invention is that when in use, the user first puts the agglomerated raw material into the feed port 21, the material enters the crushing chamber 23, and falls on the first screen 31; then the control component 8 drives the two first crushing members 32 to move closer to each other, and forms an extrusion on the agglomerated raw material. Under the action of the continuously applied extrusion force, the agglomerated raw material built between the two first crushing members 32 is continuously crushed. As the particle diameter of the raw material continues to decrease, the material that has undergone the initial crushing passes through the first screen 31 and enters the secondary crushing gap. Through the vibration of the vibrating screen 44, some of the materials whose particle size meets the sieve hole diameter of the vibrating screen 44 pass through the second screen 47 and the vibrating screen 44 in turn and enter the discharge chamber 22; then the remaining part The material whose particle size does not meet the sieve hole diameter of the vibrating screen 44 still falls on the second screen 47. The control component 8 drives the second linear drive member 45 to drive the vibration frame 46, the second screen 47 and the material to slide close to the second crushing member 43. Here, the guide plate 48 can be inserted into the accommodating groove. With the continuous extrusion force applied by the second crushing member 43, the material is crushed for the second time until the particle size meets the limit of the sieve hole diameter of the vibrating screen 44; finally, as the material continues to fall into the feeding hopper 51, the weighing sensor 53 detects that the weight of the material in the feeding hopper 51 reaches the preset value, and the control component 8 controls the third linear drive member 52 to drive the feeding hopper 51 to slide close to the discharge port 22, and finally put the material into the reactor 1.

[0057] Furthermore, fine powder generated during crushing, sieving and weighing of the material in the shell 2 is collected, and the collected fine powder enters the absorption tower 62 to achieve reprocessing or recycling of the material.

[0058] The device, through the above structure and system, can solve the technical problem in the prior art that raw material crushing and raw material unloading are two separate processes, which makes it easy to cause fine powder to fly when transporting the crushed powder material, thereby polluting the working environment.

[0059] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
