Description

Technical Field

[0001] This utility model relates to the field of ball mills, and more particularly to coarse material ball mills. Background Technology

[0002] Floral foam made from phenolic plastic foam is a key raw material for making molecular sieves. This raw material is crushed, dried, and cooled before being transferred to the grinding process. Unlike ordinary materials, phenolic plastic foam is lightweight and has already undergone fine grinding before grinding, resulting in a smaller particle size. However, the protrusions in the liner of the ball mill are at an angle to the plane, and this angle is often in the dead angle of the steel ball's impact. Therefore, more time is required for grinding, which is not only time-consuming but also more energy-intensive. Therefore, based on the above description, it is necessary to propose a coarse ball mill specifically for making molecular sieves, with the core goal of improving grinding efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a coarse material ball mill to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0005] A coarse material ball mill includes a ball mill cylinder, a base for supporting the ball mill cylinder, and a drive unit for driving the ball mill cylinder to rotate axially. The inner wall of the ball mill cylinder is lined with several liners. Each liner includes a liner body and a plurality of first grooves disposed on the liner body for contacting grinding balls and coarse material. The first grooves are spherical grooves, and the first grooves extend to the side of the liner body to form second grooves.

[0006] Preferably, the maximum diameter of the grinding ball does not exceed the spherical diameter of the first groove.

[0007] Preferably, the ball mill cylinder has an opening at the end, and the base has a shaft seat near the opening. The opening is covered with a cover, and the cover is fitted with a shaft. The shaft enters the shaft seat, and at least one shaft is a hollow shaft.

[0008] Preferably, the drive unit includes a motor fixed on the base and a transmission belt that wraps around the periphery of the ball mill cylinder and connects to the part of the motor that outputs kinetic energy.

[0009] Preferably, the ball mill cylinder wall has a feed inlet, and the feed inlet has a cover plate. The cover plate is hinged to the feed inlet, either to block the feed inlet or to expose the feed inlet to the outside.

[0010] The beneficial effects of this utility model are:

[0011] In this invention, the first groove is a cavity for receiving coarse material, and the surface of the first groove is spherical. The maximum diameter of the grinding ball does not exceed the spherical diameter of the first groove. In this way, when the grinding ball falls into the first groove, it can exert a strong impact on the coarse material in the first groove, and the impact area is much larger than the effect of planar impact, resulting in better grinding quality and grinding efficiency.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] Example 1

[0021] This embodiment proposes a coarse material ball mill; please refer to [link / reference]. Figures 1-4 The coarse material ball mill includes a ball mill cylinder 2, a base 1 for supporting the ball mill cylinder 2, and a drive unit for driving the ball mill cylinder 2 to rotate axially.

[0022] Please see Figure 1 The base 1 is a U-shaped base, which has a horizontal part and two vertical parts. The top of the two vertical parts is a bearing seat. Specifically, the bearing seats are the first bearing seat 5 and the second bearing seat 8. In addition, it should be noted that the height of the vertical part is greater than the radius of the ball mill cylinder 2.

[0023] Please see Figures 1-3 The ball mill cylinder 2 has a cylindrical structure with openings on both sides. The openings are sealed with bolted caps. Specifically, the caps are... Figure 1 The first cover 3 and the second cover 6 shown are further explained. The first cover 3 has a first shaft 4 extending outward from its axis, and the second cover 6 has a second shaft 7 extending outward from its axis. The first shaft 4 and the second shaft 7 enter the first shaft seat 5 and the second shaft seat 8 respectively, so that the ball mill cylinder 2 is mounted between the two vertical parts of the base 1 and maintains an appropriate distance from the horizontal part of the base 1.

[0024] Please see Figure 2 and Figure 3 The drive unit includes a motor 11 fixed on the base 1. The motor 11 has a reduction mechanism and a transmission belt 10. There are at least three transmission belts 10. The transmission belts 10 are wrapped around the outer periphery of the ball mill cylinder 2 and connected to the part of the motor 11 that outputs kinetic energy.

[0025] In this embodiment, it should be noted that the coarse material ball mill is equipped with several grinding balls (not shown in the figure), and at least one of the first shaft 4 and the second shaft 7 is a hollow shaft, which is used to introduce coarse material into the ball mill cylinder 2. In addition, the ball mill cylinder 2 has a material inlet on its wall, and a cover plate 9 is provided at the material inlet. The cover plate 9 is hinged to the material inlet, either to block the material inlet or to expose the material inlet to the outside.

[0026] Please see Figure 4 The inner wall of the ball mill cylinder 2 is covered with several liner plates 12. Each liner plate 12 includes a liner plate body 121 and a plurality of first grooves 122 disposed on the liner plate body 121 for contacting the grinding balls and coarse materials. The first grooves 122 are spherical grooves, and the first grooves 122 extend to the side of the liner plate body 121 to form second grooves 123. It should be noted that the grinding balls can move on the spherical surface of the first grooves 122.

[0027] Figure 4 The first groove 122 shown is a cavity for receiving coarse material, and the surface of the first groove 122 is spherical. In addition, the maximum diameter of the grinding ball does not exceed the spherical diameter of the first groove 122. In this way, when the grinding ball falls into the first groove 122 after being thrown from a high position, it can exert a strong impact on the coarse material in the first groove 122, and the impact area is much larger than the effect of planar impact, resulting in higher grinding quality and grinding efficiency.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
