Description

Technical Field

[0001] This utility model relates to the field of wear-resistant ball production technology, specifically a quenching device for wear-resistant balls in a mining ball mill. Background Technology

[0002] Mining ball mills are key grinding equipment widely used in mining, metallurgy, building materials, and chemical industries. They are mainly used to grind ores, rocks, or other hard materials into fine or ultrafine powders for subsequent mineral processing, smelting, or other processing. Wear-resistant balls are a type of grinding media used in ball mills to crush materials. During the production of wear-resistant balls, their properties need to be modified by quenching to improve their strength. During the quenching process, the heated wear-resistant balls need to be placed in a cooling tank. Current methods directly place the wear-resistant balls into the cooling tank, which easily leads to the balls piling up, affecting the cooling effect. Moreover, after cooling, the wear-resistant balls are inconvenient to remove, affecting the cooling efficiency.

[0003] To address the aforementioned issues, existing technology (Chinese Publication No.: CN221956161U) discloses a "wear-resistant ball quenching device" that uses a frame to place wear-resistant balls in batches into a cooling pool. The wear-resistant balls are loaded onto the frame via support plates, and the position of the balls is fixed by limiting holes, preventing them from stacking. This not only facilitates the loading and unloading of the wear-resistant balls but also improves their cooling effect. However, this technology still has certain drawbacks in practical use. For example, when hoisting the frame, the lack of top-limiting devices for the wear-resistant balls makes it difficult for them to fall due to shaking during hoisting and transfer. Furthermore, since multiple support plates are fixed between four columns, the spacing between adjacent support plates is limited by the fixed structure, making it difficult to increase their width. When placing the wear-resistant balls, workers are easily blocked by adjacent support plates, making it impossible to accurately place the balls into the limiting holes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a quenching device for wear-resistant balls in a ball mill for mining. The device can vertically limit the placement plate by means of a locking block, so as to prevent the wear-resistant balls from shaking and falling during the hoisting and transfer of the placement plate and the wear-resistant balls. The placement plate can be easily disassembled by means of a slider and a sliding groove. This solves the problem of difficulty in placing and picking up balls by fixing the bearing plate in the prior art, and improves the efficiency of operation.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: A wear-resistant ball quenching device for a ball mill used in mining includes: two vertical plates, six placement plates between the two vertical plates, multiple placement holes on the top of each placement plate, limit blocks installed inside each of the multiple placement holes, and locking blocks on the inner side of each of the two vertical plates.

[0006] Optionally, four connecting rods are installed on the outside of the limiting block, one end of each connecting rod is connected to the inner wall of the placement hole, wherein the connecting rods are used to fix the limiting block in the placement hole.

[0007] Optionally, a storage groove is provided on the inner side of both vertical plates, and an adjustment hole is provided on one side of the outer end of both vertical plates. The adjustment hole is connected to the storage groove, wherein the storage groove is used to store the card block.

[0008] Optionally, the adjusting hole is provided with a matching threaded rod. One end of the threaded rod is rotatably connected to the locking block through a bearing, and the other end of the threaded rod is equipped with a handwheel. Two sliding grooves are opened on the inner side of both vertical plates, and two sliders are installed on the left and right sides of the six placement plates. The sliders are used in conjunction with the sliding grooves. The threaded rod cooperates with the adjusting hole to adjust the position of the locking block.

[0009] Optionally, a horizontal plate is installed on the inner side of both vertical plates, and two lifting rings a are installed on the top of both vertical plates. Two lifting rings b are installed on both sides of the top of the placement plate. The lifting rings a facilitate the hoisting of the vertical plates with the help of an external hoist.

[0010] The beneficial effects of this utility model are: The advantage of this utility model is that by driving the threaded rod with a handwheel, the locking block slides out of the storage slot and vertically limits the top placement plate, which can stably fix the wear-resistant ball between the six placement plates and prevent it from falling off due to swaying during hoisting. Secondly, the placement plates can be flexibly loaded and unloaded by the cooperation of the slider and the chute, which makes it convenient to place wear-resistant balls on the top of multiple placement plates in sequence. After the wear-resistant balls cool down, the placement plates can be removed from top to bottom to take off the wear-resistant balls. Attached Figure Description

Detailed Implementation

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-6 As shown, a wear-resistant ball quenching device for a ball mill in mining includes: two vertical plates 1, six placement plates 101 between the two vertical plates 1, multiple placement holes 102 on the top of the placement plates 101, limit blocks 103 installed inside the multiple placement holes 102, and locking blocks 104 on the inner side of the two vertical plates 1.

[0021] The six placement plates 101 enable layered support of the wear-resistant balls, ensuring single-cycle cooling capacity and preventing the balls from squeezing against each other. They also work with the vertical plate 1 to form a stable frame for easy overall hoisting. The placement holes 102 provide lateral positioning for the wear-resistant balls and facilitate contact between the coolant and the ball surface to ensure uniform cooling. The limiting block 103 further secures the wear-resistant balls in the holes to prevent them from shaking or falling off. The locking block 104 provides vertical limiting for all placement plates 101 to prevent the placement plates 101 from becoming loose and causing the wear-resistant balls to fall off during hoisting and transfer.

[0022] The limiting block 103 is equipped with four connecting rods 2 on its outer side. One end of each connecting rod 2 is connected to the inner wall of the placement hole 102. The connecting rods 2 can stably fix the limiting block 103 inside the placement hole 102, preventing the limiting block 103 from shifting due to the placement of the wear-resistant ball or the shaking of the device. At the same time, the distribution of the four connecting rods 2 can ensure that the limiting block 103 is centered, so that it can normally limit the wear-resistant ball in the placement hole 102.

[0023] The two vertical plates 1 each have a storage groove 3 on their inner side and an adjustment hole 301 on one side of their outer end. The adjustment hole 301 is connected to the storage groove 3. The storage groove 3 is mainly used to store the card block 104. When there is no need for limiting, the card block 104 can be retracted into the groove to avoid affecting the loading and unloading of the placement plate 101. The adjustment hole 301 provides an installation and operation channel for the threaded rod 4. By rotating the threaded rod 4 through the hole, the card block 104 in the storage groove 3 can be slid out or retracted, thereby realizing the vertical limiting control of the placement plate 101.

[0024] The adjusting hole 301 is equipped with a matching threaded rod 4. One end of the threaded rod 4 is rotatably connected to the locking block 104 through a bearing, and the other end of the threaded rod 4 is equipped with a handwheel 401. The threaded rod 4 is rotatably connected to the locking block 104 through a bearing, which can both drive the locking block 104 to slide in the storage groove 3 and prevent the locking block 104 from rotating synchronously with the threaded rod 4. The handwheel 401 provides the operator with a convenient point of force. Turning the handwheel 401 can control the rotation of the threaded rod 4, thereby adjusting the extension or retraction of the locking block 104, realizing the vertical limitation or release of the placement plate 101.

[0025] Two grooves 5 are provided on the inner side of each of the two vertical plates 1. Two sliders 501 are installed on the left and right sides of each of the six placement plates 101. The sliders 501 are used in conjunction with the grooves 5. The core purpose of the grooves 5 and sliders 501 is to achieve precise installation and stable positioning of the placement plates 101. The sliders 501 are embedded in the grooves 5 to provide directional guidance for the placement plates 101 to slide between the two vertical plates 1, avoiding deviation during installation. At the same time, the two work together to fix the lateral position of the placement plates 101, preventing the placement plates 101 from shaking during subsequent hoisting and cooling, and ensuring the stability of the layered bearing wear-resistant balls.

[0026] The two vertical plates 1 are each equipped with a horizontal plate 6 on their inner sides, and two lifting rings a601 are installed on the top of each of the two vertical plates 1. Two lifting rings b602 are installed on both sides of the top of the placement plate 101. The horizontal plate 6 is mainly used to provide initial support for the first placement plate 101 at the bottom, ensuring that the placement plate 101 can be stably placed between the vertical plates 1 during the initial assembly. The two lifting rings a601 are used to cooperate with the external hoist to achieve overall hoisting, which can hoist the vertical plates 1, all placement plates 101 and wear-resistant balls into or out of the cooling pool together to meet the batch transfer requirements. The lifting rings b602 facilitate the individual hoisting of each placement plate 101 after the wear-resistant balls have cooled down, making it convenient to remove the placement plates 101 and collect the wear-resistant balls in an orderly manner, thus improving the disassembly efficiency.

[0027] Working principle: When using this device, first place the first placement plate 101 between the two vertical plates 1, and slide the slider 501 into the corresponding groove 5 until the placement plate 101 is on top of the horizontal plate 6, so that the horizontal plate 6 provides stable support for the placement plate 101. Then place the wear-resistant balls to be cooled one by one into the placement holes 102. Then slide the second placement plate 101 between the two vertical plates 1 until the placement plate 101 falls to the top of the wear-resistant balls. At the same time, ensure that the bottom of the locking block 104 is in close contact with the top of the wear-resistant balls. Then place the wear-resistant balls to be cooled into the placement holes 102 on the top of the second placement plate 101. Then place the third, fourth, fifth and sixth placement plates 101 between the two vertical plates 1 in sequence, and place the wear-resistant balls to be cooled into the placement holes 102 on the top of the third, fourth and fifth placement plates 101 in sequence. Then, the threaded rod 4 is rotated inside the adjustment hole 301 by the handwheel 401. Therefore, the threaded rod 4 can drive the locking block 104 to slide out from the storage groove 3, so that the locking block 104 moves to the top of the placement plate 101. The locking block 104 vertically limits all the placement plates 101, thereby stably limiting the wear-resistant ball between the six placement plates 101, effectively preventing the placement plates 101 from shifting during the hoisting and transfer process, causing the wear-resistant ball to fall out of the placement hole 102. Subsequently, the vertical plate 1, the six placement plates 101, and the wear-resistant balls are hoisted into the cooling pool by an external hoist with the lifting ring a601 to cool the wear-resistant balls. After the wear-resistant balls have cooled down, the vertical plate 1, the six placement plates 101, and the wear-resistant balls are hoisted out of the cooling pool by an external hoist with the lifting ring a601. Finally, each placement plate 101 is removed in order from top to bottom, and the wear-resistant balls in its placement hole 102 are collected.
