Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and more specifically, to a ball mill steel ball replenishment device. Background Technology

[0002] Grinding has a significant impact on the technical and economic indicators of a mineral processing plant. Grinding costs typically account for about 50% of the direct costs of mineral processing, making it a core part of production and operation. Ball mills rely on steel balls as the grinding medium to complete the grinding process; that is, the grinding task is accomplished through the impact and abrasion of the ore particles by the steel balls. During operation, the steel balls continuously wear down inside the ball mill. To maintain the ball filling rate and a reasonable ball ratio, it is necessary to replenish the balls appropriately to compensate for wear.

[0003] A search revealed a utility model patent with publication number CN209393272U, which discloses a ball mill steel ball replenishing device. This device includes an outer frame, a feeding roller, and a receiving trough. The patent allows for the addition of steel balls to the ball mill using three different control modes: adding an appropriate number of steel balls based on the ball mill's feed rate to maintain a balance between the amount of steel balls consumed per unit time and the amount added within the same time period, thus ensuring stable operation; continuously adding steel balls; and adding a certain amount of steel balls at regular intervals. The device is easy to use, reduces the workload of operators, and allows for more timely steel ball replenishment, contributing to stable operation of the ball mill. Furthermore, the inclusion of baffles and vibrators at the ball outlet reduces the risk of steel balls getting stuck or blocked in narrow openings, ensuring smooth passage. However, the above patents still have the following shortcomings: they are only convenient for adding steel balls of a single outer diameter. Some ball mills will add steel balls of different outer diameters, and the quantity ratio of steel balls has certain requirements. It is not convenient to add steel balls of different outer diameters in a uniform manner. Therefore, we have proposed a ball mill steel ball replenishment device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a ball mill steel ball replenishment device.

[0005] To solve the above problems, the present invention adopts the following technical solution: a ball mill steel ball replenishment device, including a replenishment cylinder, a replenishment tube fixedly connected to the bottom of the replenishment cylinder, multiple ball storage boxes fixedly sleeved on the side of the replenishment cylinder, a set of first electric push rods fixedly installed on both sides of the multiple ball storage boxes, the output ends of the two sets of first electric push rods extending into the inner cavity of the ball storage boxes and fixedly connected to a limiting plate, multiple second electric push rods fixedly installed on the top surface of the replenishment cylinder, the output ends of the multiple second electric push rods extending into the inner cavity of the replenishment cylinder and fixedly connected to an arc-shaped baffle, the multiple arc-shaped baffles being located on the side of the bottom end of the inner cavity of the limiting plate, a counting photoelectric sensor fixedly installed at the bottom end of the multiple arc-shaped baffles, and a control panel fixedly installed on the side of the replenishment cylinder.

[0006] As a preferred embodiment of this utility model, a suspension hinge is fixedly installed on the bottom surface of the top of each of the ball storage boxes, and a sealing plate is fixedly connected to the top of the suspension hinge. The sealing plate is located on the top surface of the ball storage box, and the bottom surface of the sealing plate is in contact with the top surface of the ball storage box.

[0007] As a preferred embodiment of this utility model, a scale is provided on the top surface of the ball storage box.

[0008] As a preferred embodiment of this utility model, a vibration motor is fixedly installed on the bottom surface of the ball storage box.

[0009] As a preferred embodiment of this utility model, a mounting bracket is fixedly connected to the side of the ball-filling cylinder, and the top surface of the mounting bracket is provided with multiple mounting holes.

[0010] In a preferred embodiment of this utility model, the top and bottom surfaces of the limiting plate are respectively attached to the top and bottom surfaces of the inner cavity of the ball storage box, and the bottom end of the limiting plate extends into the inner cavity of the ball replenishing cylinder.

[0011] In a preferred embodiment of this utility model, the outer side of the arc-shaped baffle is in contact with the inner wall of the ball-filling cylinder.

[0012] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, multiple ball storage boxes are set on the side of the ball replenishing cylinder, and the first electric push rod on the side of the ball storage box drives the limiting plate to move, adjusting the distance between the two limiting plates so that the distance between the two limiting plates is equal to the outer diameter of the steel ball, so that the steel ball is stored between the two limiting plates in the inner cavity of the ball storage box, realizing the storage of steel balls with different outer diameters in multiple ball storage boxes.

[0013] In this invention, when steel balls need to be added to the ball mill, multiple second electric push rods are used to drive multiple arc-shaped baffles to move upward, thereby releasing the blockage of the steel balls in the inner cavity of the ball storage box. This allows the steel balls to move from the bottom of the inner cavity of the ball storage box to the inner cavity of the ball replenishment cylinder. At the same time, the counting photoelectric sensor at the bottom of the arc-shaped baffle detects and counts the steel balls falling into each inner cavity of the ball storage box, so as to control the amount of steel balls with different outer diameters added, thereby achieving the addition of steel balls to the ball mill according to a certain ratio. This invention is highly practical. Attached Figure Description

[0023] In this embodiment, a counting photoelectric sensor 8 is used to detect the steel balls moving down from the ball storage box 3 in order to detect the number of steel balls, and the number is displayed through the control panel 9.

[0024] For details, please refer to Figure 1 Each of the top surfaces of multiple ball storage tanks 3 is fixedly equipped with a suspension hinge 10, and a sealing plate 11 is fixedly connected to the top of the suspension hinge 10. The sealing plate 11 is located on the top surface of the ball storage tank 3, and the bottom surface of the sealing plate 11 is in contact with the top surface of the ball storage tank 3.

[0025] In this embodiment, the top of the ball storage box 3 is sealed by the sealing plate 11.

[0026] For details, please refer to Figure 2 A scale 13 is provided on the top surface of the ball storage box 3.

[0027] In this embodiment, the zero point of the scale 13 is located at the middle of the top of the ball storage box 3. The scale 13 is used to measure the distance between the two limiting plates 5 inside the ball storage box 3 so that the steel ball is placed between the two limiting plates 5 for limited storage.

[0028] For details, please refer to Figure 1 A vibration motor 12 is fixedly installed on the bottom surface of the ball storage tank 3.

[0029] In this embodiment, the vibration motor 12 is used to make the ball storage box 3 vibrate so that the steel balls in the inner cavity of the ball storage box 3 can move smoothly downward.

[0030] For details, please refer to Figure 1 The ball filling tube 1 is fixedly connected to the side of the mounting bracket 14, and the top surface of the mounting bracket 14 is provided with multiple mounting holes 15.

[0031] In this embodiment, the device is installed by using the mounting bracket 14, mounting hole 15 and bolts so that steel balls can be added to the ball mill.

[0032] For details, please refer to Figure 3 The top and bottom surfaces of the limiting plate 5 are respectively attached to the top and bottom surfaces of the inner cavity of the ball storage box 3, and the bottom end of the limiting plate 5 extends into the inner cavity of the ball replenishing cylinder 1.

[0033] In this embodiment, the stability of the limiting plate 5 within the ball storage box 3 is ensured.

[0035] In this embodiment, the arc-shaped baffle 7 can block the middle part of the bottom of the inner cavity of the limiting plate 5 so as to block the steel balls stored in the inner cavity of the ball storage box 3.

[0036] Working principle: In use, open the sealing plate 11 at the top of the multiple ball storage boxes 3, and start the first electric push rod 4 on the side of the ball storage box 3. The first electric push rod 4 drives the limiting plate 5 to move, so that the distance between the two limiting plates 5 is equal to the outer diameter of the steel ball to be stored, so that steel balls of different outer diameters can be stored through multiple ball storage boxes 3. The arc-shaped baffle 7 in the inner cavity of the ball replenishing cylinder 1 is used to block the bottom steel ball. When it is necessary to add steel balls to the ball mill, start multiple second electric push rods 6 to drive multiple arc-shaped baffles 7 to move upward. This process removes the blockage of the steel balls inside the ball storage tank 3, allowing the steel balls to move from the bottom of the ball storage tank 3 to the inner cavity of the ball replenishment cylinder 1. The steel balls are then added to the ball mill through the ball replenishment pipe 2. Simultaneously, the counting photoelectric sensor 8 at the bottom of the arc-shaped baffle 7 detects and counts the steel balls falling into each ball storage tank 3, so as to control the amount of steel balls with different outer diameters being replenished. In addition, when steel balls are replenished, the vibration motor 12 at the bottom of the ball storage tank 3 is activated, which drives the ball storage tank 3 to vibrate, ensuring that the steel balls fall smoothly.
