[0002] In the process of graphite processing, mixing is an important step, which occurs after the raw materials are prepared and before forming. Specifically, mixing is to evenly mix graphite powder and binder in a certain proportion to ensure that the formed graphite product has good mechanical properties and accuracy. This step is crucial for improving the quality and performance of graphite products, because it directly affects the uniformity and consistency of the finished products. The evenly mixed raw materials can form a denser structure in the subsequent forming process, thereby improving the mechanical properties and durability of the products.

[0003] Graphite powder is easy to float on the binder and is not easy to fuse with the binder. When stirring, the graphite powder is easy to flow with the agitation of the binder. The existing mixing equipment cannot effectively force the graphite powder into the binder during stirring, and the mixing efficiency is relatively low. Summary of the Utility Model

[0008] Further, the stirring assembly further includes a scraper. A connecting rod is fixedly connected to the stirring shaft. The connecting rod is fixedly connected to the scraper.

[0018] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0019] As Figures 1 to 3 In the embodiment of the vertical mixer for graphite processing of the present utility model shown, the vertical mixer for graphite processing includes a mixing cylinder 1, a rotating stirring assembly 2 is provided inside the mixing cylinder 1, an obliquely arranged spiral cylinder 3 is fixedly connected to the upper part of the mixing cylinder 1, a rotating screw conveyor 4 is provided inside the spiral cylinder 3, the screw conveyor 4 extends into the mixing cylinder 1, a powder inlet 5 is fixedly connected to the spiral cylinder 3, a liquid agent inlet 6 is fixedly connected to the mixing cylinder 1, and a discharge port 7 is provided at the bottom of the mixing cylinder 1.

[0020] Specifically, the binder is injected into the mixing cylinder 1 from the liquid inlet 6 until the liquid level of the binder exceeds the connection between the spiral cylinder 3 and the mixing cylinder 1. Then, the screw 4 is rotated, and graphite powder is added from the powder inlet 5. The graphite powder is pressed into the binder under the push of the screw 4 and is preliminarily mixed under the rotation of the screw 4. Then, the stirring assembly 2 is rotated to gradually disperse the graphite powder incorporated into the binder and fuse it with the binder. The mixture after mixing is discharged through the discharge port and enters the next process. This device uses the screw 4 to forcibly press the graphite powder into the binder and pushes the binder incorporating the graphite powder into the binder for stirring, avoiding the graphite powder from flowing on the surface of the binder along with the agitation of the binder and improving the mixing efficiency.

[0021] In an embodiment of the present application, preferably, the stirring assembly 2 includes a stirring shaft 21 and stirring rods 22. The stirring rods 22 are fixedly connected to the stirring shaft 21, and the vertical spacing of the stirring rods 22 allows the screw 4 to pass through for stirring and mixing, avoiding the stirring rods 22 and the screw 4 from intersecting and affecting each other.

[0022] In an embodiment of the present application, preferably, the stirring assembly 2 further includes a scraper 23. A connecting rod 24 is fixedly connected to the stirring shaft 21, and the connecting rod 24 is fixedly connected to the scraper 23. The scraper 23 is in contact with the inner wall of the mixing cylinder 1, and the scraper 23 is provided with a notch for the screw 4 to pass through at the position of the screw 4, for scraping the graphite powder sticking to the cylinder.

[0023] In an embodiment of the present application, preferably, a spiral blade 25 is fixedly connected to the bottom of the stirring shaft 21 to stir the binder to roll over, so that the graphite powder around the screw 4 rolls up and down, which is beneficial for the stirring rods 22 to stir. When the graphite slurry stands still, the graphite powder will precipitate or agglomerate, and the spiral blade 25 can be used to stir and roll over the graphite powder at the bottom.

[0024] In an embodiment of the present application, preferably, a stirring motor 8 is fixedly connected to the top of the mixing cylinder 1, and the drive shaft of the stirring motor 8 is fixedly connected to the stirring shaft 21 for driving the stirring assembly 2.

[0025] In an embodiment of the present application, preferably, a feeding motor 9 is fixedly connected to the other end of the spiral cylinder 3, and the drive shaft of the feeding motor 9 is fixedly connected to the central axis of the screw 4 for driving the screw 4 to rotate and push the graphite powder into the binder.

[0026] In an embodiment of the present application, preferably, the bottom of the mixing cylinder 1 is provided with legs 10 for supporting the mixing cylinder 1, facilitating measures such as discharging, weighing, and shock absorption.

[0027] In summary, for the vertical mixer for graphite processing in the above embodiments of the present utility model, specifically, the binder is injected into the mixing cylinder 1 from the liquid inlet 6 until the liquid level of the binder exceeds the connection between the spiral cylinder 3 and the mixing cylinder 1. Then, the feeding motor 9 is started to drive the screw 4 to rotate, and graphite powder is added from the powder inlet 5. The graphite powder is pressed into the binder under the push of the screw 4 and is preliminarily mixed under the action of the rotation of the screw 4. Next, the stirring motor 8 is started to drive the stirring assembly 2 to rotate, gradually dispersing the graphite powder incorporated into the binder and fusing it with the binder. When the bottom spiral blade 25 rotates forward, the bottom binder is flipped upward, and when discharging, the stirring motor 8 is reversed, and the spiral blade 25 pushes the binder downward to facilitate discharging. The mixture after mixing is fed into the next process through the discharge port 7. This device uses the screw 4 to force the graphite powder into the binder and pushes the binder incorporating the graphite powder into the binder for stirring, avoiding the graphite powder from flowing with the stirring of the binder on the surface of the binder and improving the mixing efficiency.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
