Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a collection device for waste steel balls from a ball mill. Background Technology

[0002] A ball mill generally consists of a horizontal cylinder, hollow inlet and outlet shafts, and grinding heads. The cylinder is a long cylindrical shape, and the grinding media are installed inside. The cylinder is made of steel plate and is fixed to the cylinder by steel liners. The grinding media are generally steel balls. Ball mills are suitable for grinding various ores and other materials and are widely used in the mining industry. Nowadays, when grinding ores, it is often necessary to perform multi-stage grinding. In order to reduce the cost of mineral processing, some companies generally use the old and waste balls discharged from the first stage mill as grinding media for the second stage auxiliary mill instead of new steel segments. Therefore, a winding device is needed to collect the old and waste balls discharged from the first stage mill.

[0003] When grinding ore, steel balls of different diameters need to be placed in the ball mill in a certain proportion. However, some current waste steel ball collection devices are not convenient for separating waste steel balls of different sizes when collecting waste steel balls discharged from the first stage of the mill. This means that before the waste steel balls can be reused, they still need to be sorted manually or with the help of other equipment, which affects the efficiency of multi-stage grinding of ore. Therefore, in order to solve the above defects, the inventor proposes a waste steel ball collection device for ball mills. Utility Model Content

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This utility model discloses a device for collecting waste steel balls from a ball mill, such as... Figure 1-5 As shown, the device includes a base 1 located at the discharge port of the ball mill, a drive seat 5 fixedly installed on the left side of the top surface of the base 1, and a collection box 2 fixedly installed on the right side of the top surface of the base 1.

[0022] The drive base 5 has two slide rails 501 fixedly installed inside, and the outer surfaces of the two slide rails 501 are slidably connected to sliders 502, which can move along the slide rails 501.

[0023] A connecting plate 504 is fixedly connected between the two sliders 502. The two sliders 502 can move simultaneously through the connecting plate 504. A reciprocating screw 503 is rotatably connected inside the drive seat 5, and the connecting plate 504 is threadedly connected to the reciprocating screw 503. When the reciprocating screw 503 rotates, the connecting plate 504 will drive the two sliders 502 to reciprocate simultaneously.

[0024] The top surfaces of the two sliders 502 are fixedly mounted with a mounting frame 505. When the two sliders 502 move back and forth, they will drive the mounting frame 505 to move back and forth. The mounting frame 505 is equipped with a ball storage box 506 for collecting waste steel balls. A motor 507 is fixedly mounted on one side of the outer surface of the drive base 5, and the output end of the motor 507 is fixedly connected to the reciprocating lead screw 503.

[0025] The ball storage box 506 has a dividing frame 5062 at the opening on the top surface of the outer surface, and the inner bottom surface of the dividing frame 5062 has multiple dividing holes 5063 of different sizes to separate scrap steel balls of different diameters. A dividing frame 5061 is fixedly installed inside the ball storage box 506. The dividing frame 5061 divides the space inside the ball storage box 506, and the multiple dividing holes 5063 correspond one-to-one with the multiple divided spaces inside the ball storage box 506. Thus, scrap steel balls of different diameters will fall into the internal space of the ball storage box 506 separated by the dividing frame 5061 through the multiple dividing holes 5063 of different sizes.

[0026] Fixing plates 5064 are fixedly installed on both sides of the outer surface of the dividing frame 5062, and fastening blocks 5065 are fixedly installed on the side of the two fixing plates 5064 away from the dividing frame 5062. A mounting hole 5069 is opened on one side of the fastening block 5065.

[0027] Both sides of the outer surface of the ball storage box 506 are hinged with movable rods 5066, and a fixed frame 5067 is fixedly installed at one end of each movable rod 5066. The fixed frame 5067 has a fixed hole 5068 on both sides of its outer surface. The separating frame 5062 is placed in the opening on the top surface of the ball storage box 506, and then the two movable rods 5066 are flipped in turn so that the fixed frame 5067 is fitted onto the outer surface of the fastening block 5065. Then the mounting hole 5069 will coincide with the fixed hole 5068. After that, the bolt is inserted and the nut is used to fix the separating frame 5062.

[0028] Both sides of the mounting frame 505 are threadedly connected to threaded rods 5022, and each threaded rod 5022 has a clamping plate 5024 rotatably connected to its opposite end. Rotating the threaded rods 5022 moves the clamping plates 5024. A handle 5021 is fixedly installed at the end of each threaded rod 5022 away from the fixed plate 5064. The user holds and rotates the handle 5021 to rotate the threaded rods 5022. The inner walls of the mounting frame 505 are fixed on both sides of the fixed plate 5064. Two telescopic rods 5023 are fixedly installed, and the four telescopic rods 5023 are respectively fixedly connected to two clamping plates 5024. When the clamping plates 5024 move, they will drive the telescopic rods 5023 to move, placing the ball storage box 506 into the mounting frame 505. The two threaded rods 5022 are rotated in sequence to bring the two clamping plates 5024 closer to each other, so as to clamp and fix the ball storage box 506, so as to disassemble the ball storage box 506 and take out the waste steel balls collected in the ball storage box 506.

[0029] A sealing door 201 is hinged to one side of the outer surface of the collection box 2. A guide pipe 3 is fixedly installed on the top surface of the collection box 2, and a diversion pipe 4 is fixedly installed on one side of the outer surface of the guide pipe 3. A screen plate 301 is fixedly installed inside the guide pipe 3, and brush bristles 401 are fixedly installed on both sides of the inside of the guide pipe 3. The waste steel balls and ore discharged from the ball mill will enter the guide pipe 3. The screen plate 301 can screen the two. The screened ore will fall into the collection box 2. Since the guide pipe 3 is inclined to one side of the ball storage box 506, the screened waste steel balls will slide down through the diversion pipe 4 into the separating frame 5062. During the sliding process, the brush bristles 401 can clean the ore residue on the surface of the waste steel balls.

[0030] The working principle of this utility model is as follows: The ball mill discharges waste steel balls and ground ore through the discharge port, causing them to fall into the guide pipe 3. The screen plate 301 can screen the two materials, and the screened ore will fall into the collection box 2. Since the guide pipe 3 is inclined to one side of the ball storage box 506, the screened waste steel balls will slide through the diversion pipe 4 into the separating frame 5062. The motor 507 drives the reciprocating screw 503 to rotate, causing the slider 502 to drive the mounting frame 505 and the ball storage box 506 to move back and forth, causing the waste steel balls to shake inside the separating frame 5062. As a result, waste steel balls of different diameters will fall into the internal space of the ball storage box 506 separated by the separating frame 5061 through multiple separating holes 5063 of different sizes.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
