Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ball mill for crushing hard carbon materials. Background Technology

[0002] Hard carbon is a non-graphitized carbon material with high carbon content, high mechanical strength, and excellent thermal / chemical stability. When hard carbon is used to manufacture lithium / sodium-ion battery anodes, supercapacitors, and high-temperature sealants, it requires pulverization. Due to its high hardness, brittleness, and unique layered structure, a ball mill is typically used for pulverization.

[0003] Existing ball mills for crushing hard carbon materials have the following shortcomings: the ball mill has a feed port to discharge the crushed hard carbon material, but most ball mills are cylindrical, and the hard carbon material located at the bottom of the inner wall of the ball mill cannot be concentrated in the feed port for discharge. The ball mill discharge is incomplete, resulting in waste of the crushed hard carbon material and poor performance of the ball mill.

[0004] Therefore, those skilled in the art have proposed a ball mill for crushing hard carbon materials to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned ball mill for crushing hard carbon materials, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a ball mill for crushing hard carbon materials, which solves the problem of waste of hard carbon materials caused by incomplete discharge of the ball mill.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ball mill for pulverizing hard carbon materials, comprising:

[0009] A support frame is rotatably connected to a ball mill body on its inner wall. The ball mill body has a feeding port, and a sealing cover is installed on the outer side of the feeding port.

[0010] The feeding assembly includes two sets of fixed boxes disposed inside the ball mill body, and the fixed boxes are provided with arc-shaped scrapers and driving structures;

[0011] The drive structure, in conjunction with the arc-shaped scraper, moves laterally back and forth on the fixed box to propel the hard carbon material pulverized from the inner wall of the ball mill.

[0030] Example 1

[0031] Reference Figure 1 and Figure 3 This is the first embodiment of the present invention, which provides a ball mill for crushing hard carbon materials. This mill can concentrate the crushed hard carbon materials into the feed inlet for discharge, reducing waste. The embodiment includes:

[0032] A support 100 is rotatably connected to a ball mill body 101 on its inner wall. A discharge port 110 is provided on the ball mill body 101, and a sealing cover 111 is installed on the outer side of the discharge port 110.

[0033] The ball mill body 101 is an existing device. It uses the centrifugal force generated when the ball mill body 101 rotates and the action of the internal crushing balls to crush hard carbon materials. This is a commonly used technical means for crushing hard carbon materials. The specific working principle will not be explained here. Before use, the electrical terminals of each electrical device are electrically connected to the power supply and the electrical terminals of the controller through wires.

[0034] The feeding assembly 200 includes two sets of fixed boxes 201 disposed inside the ball mill body 101. The fixed boxes 201 are provided with arc-shaped scrapers 202 and driving structures 203.

[0035] The drive structure 203, in conjunction with the arc-shaped scraper 202, moves laterally and reciprocally on the fixed box 201 to push the hard carbon material inside the ball mill body 101 after crushing. The fixed box 201 has a certain strength to prevent the crushing balls from damaging it, and the top of the fixed box 201 is an inclined surface to facilitate the inclined feeding of the crushed hard carbon material.

[0036] During use, with the sealing cover 111 at the top, the hard carbon material is added into the ball mill body 101 through the feed port 110, and then the sealing cover 111 is closed. After starting the ball mill body 101, it is rotated. The centrifugal force generated by the rotation of the ball mill body 101 and the action of the internal crushing balls are used to crush the hard carbon material. After crushing, the sealing cover 111 is at the bottom and is opened, and the crushed hard carbon material is discharged from the feed port 110. During this process, the drive structure 203 on the pusher assembly 200 works, causing the arc-shaped scrapers 202 on the two sets of fixed boxes 201 to move in opposite directions, so that the crushed hard carbon material is concentrated in the feed port 110 and discharged, avoiding waste of hard carbon material.

[0037] Example 2

[0038] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, a mounting plate 106 is fixedly connected to the bracket 100, a drive motor 107 is mounted on the mounting plate 106, and the output end of the drive motor 107 is connected to a drive gear 108 through a rotating shaft.

[0039] The outer wall of the ball mill body 101 is fixedly connected with a toothed sleeve 109, and the toothed sleeve 109 is meshed with the drive gear 108. The operation of the drive motor 107 drives the drive gear 108 to rotate. Since the drive gear 108 is meshed with the toothed sleeve 109, the ball mill body 101, which is mounted on the support 100, can rotate.

[0040] The bracket 100 is equipped with a collection frame 102, and the inner wall of the collection frame 102 is equipped with a filter screen 103. After the sealing cover 111 is opened, the crushing ball and the crushed hard carbon material are discharged. The crushing ball and the incompletely crushed hard carbon material are located on the filter screen 103, and the completely crushed hard carbon material is located in the collection frame 102.

[0041] The collection frame 102 has four sets of moving wheels 105 fixed to the side away from the ball mill body 101. The support 100 has two sets of roller grooves 104, and the moving wheels 105 are rolled in the roller grooves 104. By the rolling of the four sets of moving wheels 105 in the roller grooves 104, the collection frame 102 can move easily on the support 100, making the collection of the crushed hard carbon material more labor-saving and improving work efficiency.

[0042] The drive structure 203 includes a geared motor 203a fixedly connected to the ball mill body 101. The output end of the geared motor 203a is connected to a lead screw 203b, and the end of the lead screw 203b away from the geared motor 203a is rotatably connected to the inner wall of the fixed box 201 through a bearing. The geared motor 203a can be powered by a battery pack on the outer wall of the ball mill body 101. The battery pack is fixedly connected inside the casing, and the casing is fixedly connected to the outer wall of the ball mill body 101.

[0043] Among them, the lead screw 203b is threadedly connected to the threaded seat 203c, and the inner wall of the fixed box 201 is fixedly connected to two sets of guide rods 203d. Each set of guide rods 203d is slidably connected to a connecting slider 203e, and the two ends of the connecting slider 203e are fixedly connected to the arc-shaped scraper 202 and the threaded seat 203c respectively.

[0044] The fixed box 201 has through slots 203f on both sides, and the through slots 203f are slidably connected to the connecting slider 203e. The operation of the reduction motor 203a drives the lead screw 203b to rotate. The threaded seat 203c, which is threaded to the lead screw 203b, is limited to sliding position by the guide rod 203d and the connecting slider 203e. The connecting slider 203e can move in the through slots 203f, which in turn drives the arc scraper 202 to move on the fixed box 201, so as to push the crushed hard carbon material at both ends of the ball mill body 101.

[0045] When in use, with the sealing cover 111 at the top, the hard carbon material is added into the ball mill body 101 through the feed port 110, then the sealing cover 111 is closed, and the drive motor 107 is started. The operation of the drive motor 107 drives the drive gear 108 to rotate. Since the drive gear 108 is meshed with the gear sleeve 109, the ball mill body 101 mounted on the support 100 can be rotated. The centrifugal force generated when the ball mill body 101 rotates and the action of the internal crushing balls are used to crush the hard carbon material.

[0046] After crushing, the geared motor 203a on the feeding assembly 200 drives the lead screw 203b to rotate. The threaded seat 203c, which is threaded to the lead screw 203b, is limited by the sliding limit of the connecting slider 203e through the guide rod 203d. The connecting slider 203e can move in the through groove 203f, which in turn drives the arc scraper 202 to move on the fixed box 201. The adjacent arc scrapers 202 move in opposite directions, so that the crushed hard carbon material is concentrated in the discharge port 110. This realizes the feeding of the crushed hard carbon material at both ends of the ball mill body 101. Then, the sealing cover 111 is opened to discharge it from the discharge port 110. The collection frame 102 and the filter screen 103 are used to collect it, reducing the waste of crushed hard carbon material.

[0047] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0048] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
