Description

Technical Field

[0001] This utility model relates to the field of ball mill equipment technology, and in particular to a ball mill jar cover with a self-separation function of grinding media. Background Technology

[0002] In the field of ball milling equipment technology, the grinding jar, as one of the core components, is widely used in processes such as material grinding and pulverization. The grinding jar achieves material refinement through the collision and friction between the internal grinding balls (such as zirconium balls, steel balls, etc.) and the material. However, how to efficiently and conveniently separate the grinding balls from the slurry (i.e., the ground material) after the ball milling operation has always been a pressing technical challenge in this field.

[0003] Currently, common ball mill jars on the market have significant shortcomings in their discharge design. When the ball mill jar completes the grinding task and opens the discharge port, the grinding balls and slurry often flow out mixed together. This mixed state results in grinding balls being mixed into the slurry, requiring additional filtration devices or manual screening steps to separate the grinding balls from the slurry. Existing separation methods mainly include the following: 1. Manual screening: The grinding balls are manually picked out of the slurry. This method is labor-intensive, inefficient, and it is difficult to guarantee complete separation. 2. Mechanical filtration: A filter screen or sieve is installed at the discharge port to retain the grinding balls through physical interception. However, this method requires regular cleaning of the filter screen, and the filtration effect is often poor for fine grinding balls or highly viscous slurries. The common drawback of the above-mentioned existing technical solutions is that they cannot automatically separate the grinding balls from the slurry when the ball mill jar discharges, leading to complex and inefficient subsequent processing steps, increasing production costs and labor input. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a ball mill jar cover with a self-separation function of grinding media, which can automatically separate the grinding balls from the slurry when the ball mill jar is discharged, so as to simplify the discharge process, improve the discharge efficiency, and reduce the post-processing cost.

[0005] To achieve the above objectives, this utility model proposes a ball mill jar lid with a self-separating function of grinding media, including a jar lid body. Multiple strip-shaped holes are arranged side by side on one side of the jar lid body. The width of the strip-shaped holes is smaller than the diameter of the grinding balls. A baffle is provided on one side of the top surface of the jar lid body. The baffle is an arc-shaped guide plate structure. The end of all the strip-shaped holes away from the center of the jar lid body is connected to the inner side of the baffle.

[0006] In the above scheme: the strip-shaped holes are evenly distributed on the tank cover body. The evenly distributed strip-shaped holes can ensure the stable flow rate of the slurry during the outflow process, reduce problems such as slurry splashing or blockage caused by sudden changes in flow rate, and improve the stability and reliability of the discharge.

[0007] In the above scheme, the upper and lower surfaces of the enclosure are both semi-circular, and the diameter of the upper surface is smaller than the diameter of the lower surface, while the diameter of the lower surface is smaller than the diameter of the can lid body, which can achieve a better flow guiding effect.

[0008] In the above scheme, the end of all the strip-shaped holes near the center of the can lid body is located on the line connecting the two ends of the lower end face of the enclosure, which can achieve a better flow guiding effect and prevent slurry overflow.

[0009] In the above scheme, the number of strip-shaped holes is 5-13, and the range of 5-13 strip-shaped holes can meet the rapid discharge requirements of most ball mill jars.

[0010] In the above scheme: the enclosure is perpendicular to the top surface of the tank lid body. The vertical design allows the slurry to fall quickly, which helps to reduce slurry residue.

[0011] In the above scheme: both the can lid body and the enclosure are made of aluminum alloy, which has the advantages of being lightweight, high-strength, and corrosion-resistant.

[0012] The beneficial effects of this utility model are as follows: 1. The multiple strip-shaped holes on the can lid body, with a width smaller than the diameter of the grinding balls, allow the slurry to flow smoothly through the strip-shaped holes when the ball mill can is tilted towards the baffle during discharge. The grinding balls, being larger than the width of the strip-shaped holes, are retained inside the ball mill can, eliminating the need for additional filtration devices or manual screening. This automatically separates the grinding balls from the slurry, greatly simplifying the discharge process and improving discharge efficiency. 2. The baffle is an arc-shaped guide plate structure, which guides and gathers the slurry flowing from the strip-shaped holes, ensuring a concentrated flow and preventing secondary pollution from splashing. This guarantees the purity of the slurry and is beneficial for subsequent processing. 3. This ball mill can lid is suitable for various specifications and types of ball mill cans. By reasonably adjusting the width and number of the strip-shaped holes and the dimensions of the baffle, it can meet the needs of different ball milling operations, demonstrating strong versatility and adaptability. Attached Figure Description

[0013] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] Figure 2 yes Figure 1Top view. Detailed Implementation

[0016] like Figure 1 As shown in Figure 2, a ball mill jar cover with a self-separating function of grinding media is mainly composed of a jar cover body 1 and multiple strip-shaped holes 2 arranged side by side on one side of the jar cover body 1.

[0017] The width of the strip-shaped hole 2 is smaller than the diameter of the grinding ball. A baffle 3 is provided on one side of the top surface of the can lid body 1. The baffle 3 is an arc-shaped guide plate structure. The end of all the strip-shaped holes 2 away from the center of the can lid body 1 is connected to the inner side of the baffle 3.

[0018] The strip-shaped holes 2 are evenly distributed on the tank cover body 1. The evenly distributed strip-shaped holes can ensure the stable flow rate of the slurry during the outflow process, reduce problems such as slurry splashing or blockage caused by sudden changes in flow rate, and improve the stability and reliability of the discharge.

[0019] The upper and lower ends of the enclosure 3 are both semi-circular, with the diameter of the upper end being smaller than that of the lower end, and the diameter of the lower end being smaller than that of the can lid body 1, which can achieve a better flow guiding effect.

[0020] All the strip-shaped holes 2 have one end near the center of the can lid body 1 located on the line connecting the two ends of the lower end face of the enclosure 3, which can achieve a better flow guiding effect and prevent the slurry from overflowing.

[0021] When discharging from the ball mill jar, tilt the jar towards the enclosure 3 (when the ball mill jar is a small laboratory ball mill jar, it can be tilted manually; when the ball mill jar is a large jar used in the factory, it can be tilted with the help of tools, such as installing the ball mill jar on a tiltable base). The slurry can flow out smoothly through the strip-shaped holes 2, while the grinding balls, because their size is larger than the width of the strip-shaped holes 2, are trapped inside the ball mill jar. Without the need for additional filtration devices or manual screening steps, the separation of the grinding balls and the slurry can be achieved automatically, greatly simplifying the discharge process and improving the discharge efficiency.

[0022] The number of strip-shaped holes 2 is 5-13, and this range of 5-13 strip-shaped holes can meet the rapid discharge requirements of most ball mill jars.

[0023] The enclosure 3 is perpendicular to the top surface of the tank lid body 1. The vertical design allows the slurry to fall quickly, which helps to reduce slurry residue.

[0024] Both the can lid body 1 and the enclosure 3 are made of aluminum alloy, which has the advantages of being lightweight, high-strength, and corrosion-resistant.
