A stirring cylinder is fixedly connected to the top right side of the base. A cylinder cover is rotatably connected to both the left and right sides of the top wall of the stirring cylinder. Ball bearings are installed on the front and rear sides of the top wall of the stirring cylinder.

Description

Technical Field

[0001] This utility model relates to the field of turbine sand mill technology, and more particularly to a multi-axis turbine sand mill. Background Technology

[0002] Multi-axis turbine sand mills are upgraded equipment developed from traditional single-axis turbine sand mills. By introducing the design concept of multi-axis coordinated motion, they further improve grinding efficiency, material throughput and grinding uniformity. They are suitable for industrial scenarios with higher requirements for grinding precision and production capacity. The most significant feature of multi-axis turbine sand mills is that they are equipped with multiple or more independently driven turbine shafts, each with a turbine disc installed on it, and the shafts achieve coordinated motion through a specific transmission and control mechanism.

[0003] In existing technologies, a motor drives a turbine disc to rotate at high speeds, typically reaching thousands of revolutions per minute. The turbine disc has multiple abrasive dispersion holes that can circulate and spray grinding media. When material enters the abrasive dispersion chamber from the feed hopper, it is dispersed in all directions by the centrifugal force of the high-speed rotating turbine disc. Simultaneously, the material's own gravity generates a couple parallel to the cylinder axis, exerting a reaction force on the cylinder. Under the combined action of high-speed rotation and material gravity, intense collisions and friction occur between the grinding media and the material, resulting in grinding and dispersion. However, multi-axis coordinated motion requires overcoming the additional resistance of inter-axis flow field interference and media collisions, leading to higher energy consumption per unit output compared to single-axis equipment. Currently, sensors monitor material viscosity and grinding chamber pressure in real time, dynamically adjusting the speed of each axis (e.g., reducing the speed of the outer axis for low-viscosity materials) to avoid ineffective energy consumption. However, replacing turbine blades requires disassembling the grinding chamber and separation device components, which is cumbersome, results in long downtime, and increases equipment maintenance costs and the risk of production interruption. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-axis motion turbine sand mill, which aims to improve the problem that in the prior art, when replacing turbine blades, it is necessary to disassemble the grinding chamber, separation device and other components, which is cumbersome to operate, has a long downtime, and increases the maintenance cost of the equipment and the risk of production interruption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-axis rotating turbine sand mill, comprising a base, a stirring cylinder fixedly connected to the top right side of the base, cylinder covers rotatably connected to the left and right sides of the top wall of the stirring cylinder, ball bearings installed on the front and rear sides of the top wall of the stirring cylinder, a fixing mechanism installed inside the ball bearings, the fixing mechanism being used to fix and disassemble components, a shock-absorbing mechanism installed at the bottom of the base, the shock-absorbing mechanism being used to reduce the vibration impact on the equipment; the fixing mechanism includes a fixing block, the fixing block being fixedly connected to the inside of the ball bearings, a partition plate being fixedly connected to one end of the fixing block, turbine blades being installed inside the partition plate, multiple bolts being threaded at equal intervals on the outer wall of the fixing block, and multiple sliding grooves being opened at equal intervals on the outer wall of the fixing block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, rotating the bolt allows the slider to slide within the groove, enabling it to slide outwards along the groove. This allows the clamping block to rotate along the outer wall of the partition, causing the end of the clamping block to converge towards the center of the partition. The clamping block then engages with the grooves at both ends of the turbine blade, securing it in place. Rotating the bolt again causes the end of the bolt to press against the outer wall of the slider, fixing the slider within the groove.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a multi-axis rotating turbine sand mill, comprising a base 1, a mixing drum 2 fixedly connected to the top right side of the base 1, a drum cover 10 rotatably connected to the left and right sides of the top wall of the mixing drum 2, ball bearings 3 installed on the front and rear sides of the top wall of the mixing drum 2, a fixing mechanism 4 installed inside the ball bearings 3, the fixing mechanism 4 being used to fix and disassemble components, and a shock-absorbing mechanism 5 installed at the bottom of the base 1, the shock-absorbing mechanism 5 being used to reduce the vibration impact on the equipment; the fixing mechanism 4 includes a fixing block 401, the fixing block 401 being fixedly connected to the inside of the ball bearings 3, the fixing block 401... One end is fixedly connected to a partition plate 406, and a turbine blade 11 is installed on the inner side of the partition plate 406. Multiple bolts 402 are threaded at equal intervals on the outer wall of the fixing block 401, and multiple sliding grooves 403 are opened at equal intervals on the outer wall of the fixing block 401. A slider 404 is slidably connected to the inner wall of the sliding groove 403, and a clamping assembly 405 is installed on the outer wall of the slider 404. The clamping assembly 405 includes a connecting block 4051, which is fixedly connected to the outer wall of the slider 404. A clamping block 4052 is rotatably connected to the outer wall of the connecting block 4051, and the inner wall of the clamping block 4052 is rotatably connected to the outer wall of the partition plate 406.

[0032] Specifically, rotating bolt 402 reduces the pressure on slider 404 within slide groove 403, allowing slider 404 to slide within slide groove 403. Pulling connecting block 4051 outward allows slider 404 to slide outward along slide groove 403, causing clamping block 4052 to rotate along the outer wall of partition 406. This causes the end of clamping block 4052 to converge towards the center of partition 406, securing clamping block 4052 into the grooves at both ends of turbine blade 11. Rotating bolt 402 again causes the end of bolt 402 to abut against the outer wall of slider 404, fixing slider 404 within slide groove 403. This prevents slider 404 from sliding out of slide groove 403, causing clamping block 4052 to open and loosen turbine blade 11. The operation is convenient, facilitating the fixing and disassembly of turbine blade 11, shortening downtime, and reducing equipment maintenance costs and production interruption risks.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The shock absorption mechanism 5 includes a telescopic rod 505, which is fixedly connected to the left and right sides of the inner wall of the base 1. A connecting component 504 is installed at the top of the telescopic rod 505. The connecting component 504 includes a clamping plate 5042, which is fixedly connected to the top of the telescopic rod 505. A second rotating shaft 5041 is rotatably connected to the inner wall of the clamping plate 5042. A crank 503 is rotatably connected to one end of the second rotating shaft 5041. A first rotating shaft 502 is rotatably connected to the inner wall of the crank 503. A locking block 501 is rotatably connected to the end of the first rotating shaft 502. The top wall of the locking block 501 is connected to the bottom wall of the base 1.

[0034] Specifically, during equipment operation, the vibrations generated are transmitted to the base 1. The base 1 vibrates and shakes the locking block 501. The locking block 501 moves downward and drives the first rotating shaft 502, which in turn transmits the crank 503 to the second rotating shaft 5041. This causes the clamping plate 5042 to compress the telescopic rod 505. The telescopic rod 505 continuously extends and retracts to offset the vibration force, absorb and buffer the vibration energy, further improve the structure's vibration resistance, prevent components from loosening, wearing, or even being damaged due to long-term vibration, and extend the service life of the equipment.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A motor 6 is fixedly connected to the left side of the top wall of the base 1, and a turntable 9 is fixedly connected to the inner side of the ball bearing 3; a turntable 7 is fixedly connected to the output end of the motor 6, and the motor 6 is connected to the turntable 9 via a belt 8.

[0036] Specifically, after the motor 6 starts, it drives the first turntable 7 to rotate. After the first turntable 7 rotates, it drives the transmission belt 8. The belt 8 then drives the second turntable 9 to rotate together. After the second turntable 9 rotates, it drives the inner ball bearing 3 to rotate, thereby driving the fixed block 401 and the turbine blade 11. The turbine blade 11 rotates to accelerate the slurry, causing the slurry to collide and grind inside the mixing drum 2.

[0037] Working principle: By rotating bolt 402 clockwise and counterclockwise, the pressure on slider 404 located in groove 403 is gradually reduced. Once the pressure on slider 404 is reduced, it can slide within the groove 403. At this point, pulling connecting block 4051 outwards causes slider 404 to slide outwards along groove 403. As slider 404 slides outwards, it drives the connected structure, causing clamping block 4052 to rotate along the outer wall of partition 406. During rotation, the end of clamping block 4052 gradually moves towards the partition. When the center of the clamping block 4052 converges to a certain extent, it can be fastened into the grooves set at both ends of the turbine blade 11, thus firmly fixing the turbine blade 11. After fixing, the bolt 402 is rotated again, so that the end of the bolt 402 is pressed tightly against the outer wall of the slider 404. This can fix the slider 404 firmly in the slide groove 403, effectively preventing the slider 404 from sliding out of the slide groove 403. The operation is very convenient. Whether fixing or disassembling the turbine blade 11, it is very convenient. This can not only shorten the downtime of the equipment, but also reduce the maintenance cost of the equipment and reduce the risk of production interruption.

[0038] When the equipment is running, the vibrations generated during operation are gradually transmitted to the base 1. After receiving the vibrations, the base 1 will also vibrate accordingly. This shaking will act on the locking block 501, causing it to move downwards and transmit this motion to the rotating shaft 502. After receiving the motion transmitted from the locking block 501, the rotating shaft 502 will transmit it to the crank 503. After receiving the transmission from the rotating shaft 502, the crank 503 will further transmit the rotating shaft 5041. As the rotating shaft 5041 moves, the clamping plate 5042 will compress the telescopic rod 505. After being compressed, the telescopic rod 505 will continuously extend and retract, using this extension and retraction to counteract the vibration force generated by the equipment operation. During the extension and retraction process, the telescopic rod 505 can effectively absorb and buffer vibration energy, thereby further improving the vibration resistance of the entire structure. In this way, the equipment can avoid loosening, wear, or even damage to components due to long-term exposure to vibration, thus extending the service life of the equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
