Description

Technical Field

[0001] The utility model relates to the technical field of superhard powder crushing devices, and more specifically, to a superhard powder crushing device. Background Art

[0002] In the current field of superhard powder crushing technology, common crushing methods rely on multi-stage processing and assembly line operations. Under this model, workers need to control and test the powders one by one, and then adapt equipment of different strengths for auxiliary processing according to the characteristics of the powders. Although this method can complete the crushing task to a certain extent, it brings high labor costs and equipment stacking costs, which not only affects production efficiency, but may also have an adverse effect on the quality of the final product.

[0003] To overcome these problems, some existing technologies have attempted to use airflow pulverization to process superhard powders. This technology uses high-speed airflow to impact and pulverize powders, aiming to improve efficiency and reduce dependence on manual labor. However, the pipeline structure of these devices is often too simple and lacks the ability to flexibly control the gas flow rate. This limitation makes it difficult to control the pulverization effect. The instability of the flow rate will directly affect the pulverization efficiency and the uniformity of the powder particle size, thereby adversely affecting product quality.

[0004] Furthermore, some devices attempt to solve the above problems by establishing specific mechanisms to adjust the flow rate of the airflow. However, the design of these adjustment mechanisms is usually simple and easily affected by equipment vibration and external factors. During long-term operation, the adjustment device may become loose, which will change the pre-adjusted flow rate setting and cause unstable flow rate. This instability not only affects the crushing effect, but may also increase safety risks in the production process, and have an adverse effect on production efficiency and equipment life.

[0018] Beneficial effects:

[0019] 1. The beneficial effects of the crushing device are mainly reflected in its efficient crushing capacity and fine material handling. The feed hopper receives the powder raw materials and transports the raw materials to the crushing bin through the conveying pipe and the discharge hopper. The guide cavity and crushing cavity design inside the crushing bin, as well as the air holes on the side wall, can make the air flow form a vortex, enhancing the crushing effect. The presence of the tapered tube further ensures the crushing effect of the powder, so that the powder that meets the diameter requirements can pass smoothly. The crushed powder enters the separation tank through the feed pipe, is filtered by the filter plate, and settles into the collection bucket, while the gas is sucked into the fan and discharged through the exhaust pipe.

[0020] 2. The beneficial effect of the adjustment device is reflected in its precise flow rate adjustment capability. Through simple operation, the gap of the air flow channel is adjusted, affecting the flow rate of the gas. This design allows the operator to accurately adjust the flow rate as needed to ensure the consistency and stability of the crushing effect.

[0021] 3. The beneficial effects of the protective mechanism are reflected in its protection of equipment stability and improvement of operational safety. The design of the protective mechanism includes components such as connecting blocks, connecting rods, springs, control sleeves, push springs, push sleeves, limit plates, limit frames and fixed blocks. They work together to ensure the stability of the push sleeve and the precise control of the control sleeve after airflow adjustment. This protective mechanism not only prevents the adjustment device of the equipment from loosening due to vibration or external force, but also ensures the stability after flow rate adjustment, thereby improving the reliability of the equipment and the safety of operation.

At this time, the outer side of the rotating sleeve 9 loses the limit of the push sleeve 16, and then the rotating sleeve 9 is rotated, and the rotating sleeve 9 drives the screw rod 10 through the connecting frame 7. 6 rotates, since the screw sleeve 4 and the screw rod 6 are movably connected by threads, and the slider 23 and the slide groove 22 limit the sliding frame 3, the screw sleeve 4 will drive the sliding frame 3 to slide along the slider 23 and the slide groove 22, so that the distance between the sliding frame 3 and the movable frame 8 changes, and the gap between the elastic plate 5 changes, thereby achieving the purpose of adjusting the flow rate. After the adjustment is appropriate, the rotating sleeve 9 is loosened, and then the control sleeve 14 is rotated. The control sleeve 14 drives the connecting block 10 to compress the spring 12 again, and then the position of the slot 13 and the limiting plate 17 is adjusted. Correspondingly, the push spring 15 then pushes the push sleeve 16 to reset along the guide rail 20 and the guide groove 21, so that the push sleeve 16 is again fitted to the outside of the rotating sleeve 9 to limit the rotating sleeve 9, and then the push spring 15 is completely reset, and then the control sleeve 14 is released, and the spring 12 pushes the connecting block 10 again to drive the control sleeve 14 to reset, so that the position of the limit plate 17 and the give way groove 13 correspond, and then the corresponding two limit plates 17 will be engaged on both sides of the control sleeve 14, thereby limiting the push sleeve 16 and preventing the push sleeve 16 from moving, further ensuring the stability of the flow rate after adjustment.

Then the powder is added to the lower bin 26. The lower bin 26 is sealed and the air pump 28 is turned on at the same time. The air pump 28 at the top conveys the compressed gas through the conveying pipe 27. The air pump 28 at the bottom conveys the compressed gas to the guide chamber 31 through the air pipe 29. Then, the compressed gas is sprayed into the crushing chamber 32 along the tangential direction through the air hole 33, so that the air flow forms a vortex airflow in the crushing chamber 32. Then, the powder in the lower bin 26 is conveyed to the feed hopper 24 due to negative pressure and gravity. Then, the powder in the feed hopper 24 enters the conveying pipe 27 and follows the high pressure. The gas is transported into the crushing chamber 32, and then the faster-flowing powder and the slower-flowing powder will collide with each other due to the action of the supersonic gas to produce a crushing effect.
