Description

Technical Field

[0001] The utility model relates to the technical field of graphite pretreatment equipment, in particular to a graphite pretreatment mixed material processing device. Background Art

[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with acids, alkalis and other agents. In the preparation of negative electrode materials for lithium batteries, graphite materials need to be pretreated and the dried or powdered graphite materials are mixed with other ingredients (such as binders, asphalt, etc.) to prepare a mixture suitable for subsequent processing.

[0003] When using graphite materials to prepare negative electrode materials for lithium batteries, the graphite needs to be pretreated for the following reasons: On the one hand, the dried or powdered graphite material may have problems with adhesion and agglomeration due to moisture and other factors. If it is directly added to the mixing equipment, the mixing effect is poor and the mixing time is increased. On the other hand, when the graphite material is mixed with other ingredients, the raw materials are easy to adhere to the inner wall of the mixing equipment, affecting the mixing quality.

[0004] Therefore, the present application provides a graphite pretreatment mixture processing device to meet the needs. Utility Model Content

Example

[0026] refer to Figure 1-5 A graphite pretreatment mixing processing device shown includes a mixing barrel 1 and a mixing cover 2, wherein the mixing barrel 1 is a shell with a transparent top surface, and the mixing barrel 1 includes a cylindrical portion and an arc portion, and a support leg 4 and a discharge port 5 are provided at the bottom of the mixing barrel 1, and a solenoid valve is provided at the discharge port 5, and the opening and closing of the solenoid valve can control whether the material in the mixing barrel 1 is discharged from the discharge port 5, and the mixing barrel 1 is connected to the mixing cover 2 sealed to the top through a hydraulic cylinder 3; a support ear 15 is welded on the outer wall of the mixing barrel 1, and the support ear 15 is provided with two groups, and the fixed end of the hydraulic cylinder 3 is connected to the support ear 15, and the mixing cover 2 is provided with a mounting plate 16 connected to the telescopic end of the hydraulic cylinder 3;

[0027] The mixing cover 2 is provided with a first feeding port 6 and a second feeding port 7 for adding materials to the mixing barrel 1. The mixing cover 2 is also rotatably connected with a mixing paddle 8 through a bearing seat. The mixing paddle 8 is located at the center of the mixing cover 2. The mixing paddle 8 is driven by a motor 9, and the motor 9 is installed on the mixing cover 2 through a motor frame. The mixing paddle 8 is located inside the mixing barrel 1 and is used for mixing materials; the mixing paddle 8 includes a rotating shaft 81 and a paddle 82, the rotating shaft 81 is coaxially arranged with the mixing barrel 1, the paddle 82 is installed on the rotating shaft 81 by bolts, and the rotating shaft 81 is connected to a side scraper 83 for cleaning the inner side wall of the mixing barrel 1 through a connecting rod 85, the connecting rod 85 and the paddle 82 are staggered, and the side scraper 83 is tilted, such as Figure 5 As shown, when the side scraper 83 rotates with the rotating shaft 81, it can scrape the material on the inner wall of the mixing barrel 1 and push it downward. The bottom of the rotating shaft 81 is also connected to a bottom scraper 84 for cleaning the inner bottom surface of the mixing barrel 1.

[0028] The mixing barrel 1 is also provided with a bulk material piece 10 for evenly adding materials, and the bulk material piece 10 corresponds to the position of the first feed port 6, and the bulk material piece 10 and the second feed port 7 are staggered. When adding materials to the mixing barrel 1, the materials added through the first feed port 6 will first fall on the bulk material piece 10 and then fall into the mixing barrel 1, and the materials added through the second feed port 7 will directly fall into the mixing barrel 1.

[0029] The bulk material part 10 includes a ring frame and a filter screen. The ring frame is made of ABS material, and the filter screen is made of stainless steel. The two are hot pressed together. The ring frame is provided with a connecting plate 13 for connecting with the mixing barrel 1. The inner wall of the mixing barrel 1 is connected with a support rod 12 through a support 11. The connecting plate 13 is provided with a mounting hole for plugging with the support rod 12. The plugging of the connecting plate 13 and the support rod 12 makes it convenient for the staff to remove the bulk material part 10 from the mixing barrel 1 for maintenance and cleaning.

[0030] The filter screen is provided with a through hole for the shaft 81 to pass through, and the diameter of the through hole is larger than the diameter of the shaft 81. The mixing paddle 8 is provided with a bulk material plate 14 for moving the material on the bulk material part 10. The bulk material plate 14 is slidably connected to the filter screen, and the bulk material plate 14 is tilted. Figure 4 As shown, when the bulk plate 14 rotates with the rotating shaft 81, the graphite material accumulated on the filter screen is pushed, and the graphite material passes through the filter screen and falls into the mixing barrel 1, so that the graphite material is evenly added. While the graphite material is pushed, the adhered or agglomerated graphite rolls on the filter screen to disperse it, thereby shortening the mixing time. If a large amount of graphite material is added at one time and it cannot pass through the filter screen, the inclined bulk plate 14 will push the graphite material toward the rotating shaft 81 and add it to the mixing barrel 1 from the through hole at the center of the filter screen.

[0031] The working principle of the utility model is as follows: when in use, the device is connected to electricity, the electromagnetic valve at the material outlet 5 is controlled to be closed, and graphite material is added to the mixing barrel 1 through the first material inlet 6 on the mixing cover 2. The added graphite material falls on the bulk material part 10, and part of the graphite material passes through the filter screen on the bulk material part 10 and falls into the mixing barrel 1. The motor 9 is connected to electricity and started, and the motor 9 drives the rotating shaft 81 to rotate, and drives the bulk material plate 14 to rotate. The bulk material plate 14 slides on the filter screen of the bulk material part 10, and pushes the graphite material accumulated on the filter screen, so that the graphite material rolls on the filter screen, and the agglomerated or adhered graphite material is dispersed during rolling. At the same time, the graphite material passes through the filter screen and falls into the mixing barrel 1. Due to the inclined setting of the bulk material plate 14, the bulk material plate 14 will push the graphite material to the center of the filter screen while rotating, and the graphite material that cannot pass through the filter screen will fall into the mixing barrel 1 from the through holes of the filter screen, contact with the paddle 82 below, and be hit and dispersed by the paddle 82.

[0032] Other ingredients are added from the second feed port 7 on the mixing cover 2. The second feed port 7 is offset from the bulk material 10. Other ingredients are directly added to the mixing barrel 1 and mixed with the graphite material under the mixing of the mixing paddle 8. During the mixing process, some materials will adhere to the inner wall of the mixing barrel 1. When the rotating shaft 81 rotates, the side scraper 83 is driven to rotate through the connecting rod 85 to scrape the inner wall of the mixing barrel 1 to prevent the material from adhering to the inner wall of the mixing barrel 1. The side scraper 83 is tilted. When the side scraper 83 scrapes, the material adhering to the inner wall is pushed downward; when the rotating shaft 81 rotates, it drives the bottom scraper 84 to scrape the inner bottom surface of the mixing barrel 1 to prevent the material from adhering to the inner bottom surface of the mixing barrel 1, thereby accelerating the mixing of the materials; after the mixing is completed, the battery valve at the discharge port 5 is opened to discharge the mixed material from the discharge port 5.
