Description

Technical Field

[0001] This utility model relates to the field of hard carbon production technology, specifically to a biomass hard carbon precursor production device. Background Technology

[0002] Hard carbon materials are excellent battery materials with high specific capacity, good cycle stability and low cost. Modern technology is increasingly using biomass precursors (such as wood, straw, coconut shells, etc.) to prepare hard carbon. However, due to the complex composition of the materials, the pre-made materials need to be screened and mixed again before production to ensure high uniformity of the materials during high-temperature processing. Existing equipment requires multiple devices to work in multiple steps during screening and mixing, which is inefficient. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a screening barrel, a mixing barrel connected to the bottom of the screening barrel, the mixing barrel being supported by several support legs, a discharge gate at the bottom of the mixing barrel, a screw feeder connected to the top side of the screening barrel, a feed chute on the screw feeder, a feed cover on the feed chute, a drive assembly for driving the feed cover on the feed chute, a screening assembly inside the screening barrel, and a stirring structure inside the mixing barrel.

[0005] Preferably, the drive assembly includes support blocks installed on both sides of the feed trough, a guide slider connected to the top of the support block, slide rails connected to both sides of the feed cover, the slide rails slidably connected to the guide sliders, a groove in the middle of the outer side of the slide rail, a drive rack in the groove, a drive box installed on the support block, a drive motor installed in the drive box, and a drive gear connected to the shaft of the drive motor through a reduction gear set, the drive gear meshing with the drive rack.

[0009] The beneficial effects of this utility model after adopting the above structure are:

[0010] 1. This utility model uses a drive component to open the feed cover for feeding via electric drive, which is convenient to use. After feeding is completed, the cover can be closed to prevent material from flying out. A screw feeder is used for feeding to ensure uniform feeding speed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figures 1-4 As shown, it includes a screening barrel 1, a mixing barrel 13 connected to the bottom of the screening barrel 1, and the mixing barrel 13 is supported by several support legs. The bottom of the mixing barrel 13 is provided with a discharge gate 24. A screw feeder 2 is connected to the top side of the screening barrel 1. The screw feeder 2 is provided with a feeding trough 3. The feeding trough 3 is provided with a feeding cover 4. The feeding trough 3 is provided with a drive assembly for driving the feeding cover 4. The screening barrel 1 is provided with a screening assembly. The mixing barrel 13 is provided with a stirring structure.

[0021] See Figures 1-4 As shown, the drive assembly includes support blocks 5 installed on both sides of the feed trough 3. A guide slider 6 is connected to the top of the support block 5. Slide rails 8 are connected to both sides of the feed cover 4. The slide rails 8 are slidably connected to the guide slider 6. A groove is opened in the middle of the outer side of the slide rail 8. A drive rack 9 is provided in the groove. A drive box 7 is installed on the support block 5. A drive motor 10 is installed in the drive box 7. The shaft of the drive motor 10 is connected to a drive gear 12 through a reduction gear set 11. The drive gear 12 meshes with the drive rack 9.

[0022] The combination of guide slider 6 and slide rail 8 allows the feed cover 4 to slide. At the same time, the drive motor 10 provides power output, which is reduced by the reduction gear set 11 and then driven by the drive gear 12 to push the drive rack 9, thereby driving the feed cover 4 to open and close.

[0023] See Figures 1-3 As shown, the screening assembly includes several inclined screens 14, with the upper and lower screens 14 connected to each other. Each screen 14 has a discharge port 15 at the lowest point of the screening barrel 1. A discharge trough 16 is provided on the outside of the discharge port 15. Multiple drivers 19 are provided inside the screening barrel 1. A top motor 26 is provided inside the driver 19. A cam 27 is connected to the shaft of the top motor 26. A sliding rod 25 is slidably installed on the top of the driver 19 in the vertical direction. The sliding rod 25 is located above the cam 27. The top of the sliding rod 25 is connected to the screen 14.

[0024] The cam 27 is rotated by the top motor 26, which in turn pushes the sliding rod 25 to move upward and then falls back downward under the action of gravity. This cycle repeats, which can drive multiple screens 14 to shake up and down at the same time, thus accelerating the screening.

[0025] See Figures 1-2 As shown, each screening barrel 1 is equipped with a movable door 18 at the discharge port 15, and each screening barrel 1 is equipped with a telescopic cylinder 17 above the movable door 18. The movable end of the telescopic cylinder 17 is connected to the movable door 18.

[0026] An active gate 18 is installed to block the material on the screen 14, so that the material can be continuously screened, extending the screening time and preventing premature discharge that would lead to material waste.

[0027] See Figures 1-2 As shown, the stirring structure includes a mixing motor 22 disposed downward in the mixing tank 13. A spiral mixing paddle 23 is connected to the rotating shaft of the mixing motor 22. A conical dust cover 21 is installed inside the mixing tank 13 through several triangular support rods 20. The mixing motor 22 is installed below the dust cover 21.

[0028] The mixing motor 22 drives the spiral mixing paddle 23 to stir and mix the material. The dust cover 21 and the triangular support rod 20 are set to guide the material to prevent material accumulation or damage to the mixing motor 22.

[0029] The usage process of this utility model:

[0030] First, install the device in place, then start the drive motor 10, open the feed cover 4, add the required material, and start the drive motor 10 in reverse, close the feed cover 4, and then start the remaining power mechanism. The screw feeder 2 feeds the material into the screening bucket 1 at a uniform speed. The movable door 18 remains closed. The material is screened out and falls on the screen 14 that is shaking up and down until it reaches the mixing bucket 13 and is stirred. The material that does not meet the requirements will accumulate at the discharge port 15. When the work is completed, the material can be automatically discharged when the movable door 18 is opened. The material after stirring can be discharged by opening the discharge door 24.

[0031] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
