[0002] Aluminum granules are an important material in the metal processing field. Different application fields have very strict requirements on the particle size range (particle size distribution), uniformity (particle size concentration) and particle shape of aluminum granules. Therefore, efficient and accurate screening (grading) of aluminum granules according to the target particle size range is a key step in the production of aluminum granule products.

The spatial position is permanently fixed after the equipment leaves the factory and cannot be adjusted according to actual production needs. However, fixed discharge ports are often difficult to match precisely, resulting in excessive drop and splashing of aluminum particles when they are discharged. Therefore, in order to solve the above-mentioned problems, an improved multi-stage cyclone aluminum particle screening device is proposed. Utility Model Content

[0020] 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.

[0021] This utility model provides, for example Figures 1-4 The multi-stage cyclone aluminum particle screening device shown includes a mounting frame 1, which is arranged in a stepped manner, and cyclone bodies 2 that provide screening function for aluminum particles are installed on the mounting frame 1 from high to low, and two adjacent cyclone bodies 2 are interconnected.

[0022] The bottom of the mounting frame 1 is provided with multiple collection boxes 3, and the discharge port of the hydrocyclone body 2 is provided with a telescopic mechanism 4 that can adjust the distance from the collection box 3.

[0023] The mounting frame 1 is arranged in a stepped manner, so that the hydrocyclone body 2 can be installed sequentially from high to low. The aluminum particles are guided to flow between each level of hydrocyclone body 2 by gravity. Adjacent hydrocyclone bodies 2 are interconnected to realize multi-stage progressive screening of aluminum particles. The collection box 3 at the bottom of the mounting frame 1 is used to receive the screened aluminum particles, while the telescopic mechanism 4 of the discharge port can flexibly adjust the distance between the discharge port and the collection box 3.

[0024] The stepped layout uses gravity to improve the continuity and efficiency of aluminum particle screening. Multi-stage cyclone screening can improve the accuracy of aluminum particle size classification. The telescopic mechanism 4 solves the matching problem between the fixed discharge port and the collection box 3, reduces aluminum particle splashing loss, and at the same time improves the adaptability of the device to different collection scenarios and enhances production flexibility.

[0025] The working principle of the hydrocyclone body 2 screening mainly relies on the synergistic effect of centrifugal sedimentation and fluid dynamics. Separation is achieved by the stratification of particles of different densities or sizes under centrifugal force. When the material enters the hydrocyclone tangentially, a three-dimensional elliptical strong rotating shear turbulence is generated in the rotational motion. At this time, the coarse particles, due to the greater centrifugal force, will move downward along the wall of the device and be discharged from the bottom outlet, while the fine particles, due to the smaller centrifugal force, will move towards the central axis, forming an upward-moving inner vortex, and finally be discharged through the overflow pipe.

[0026] The telescopic mechanism 4 includes a telescopic tube 41. The upper end of the telescopic tube 41 is connected to the outlet of the hydrocyclone body 2 via a connector 42. A snap-fit ​​component 43 is provided at the connection position between the connector 42 and the outlet of the hydrocyclone body 2. A flow guide shroud 44 is fixedly connected to the lower end of the telescopic tube 41.

[0027] The core of the telescopic mechanism 4 is the telescopic tube 41, the upper end of which is connected to the discharge port of the hydrocyclone body 2 through the connector 42. The snap-fit ​​component 43 can firmly fix the connector 42 to the discharge port. By adjusting the telescopic length of the telescopic tube 41, the distance between the discharge port and the collection box 3 can be changed. The guide shroud 44 at the lower end guides the aluminum particles to flow into the collection box 3.

[0028] The telescopic feature of the telescopic tube 41 enables convenient adjustment of the outlet distance, meeting the docking requirements of collection boxes 3 of different heights. The snap-fit ​​component 43 ensures the stability of the connection between the telescopic mechanism 4 and the outlet, preventing loosening and leakage during material conveying. The guide shroud 44 further guides the aluminum particles to fall in a concentrated manner, reducing scattering losses.

[0029] The snap-fit ​​assembly 43 includes a snap-fit ​​431. One end of the snap-fit ​​431 is hinged by a hinge. The inner side of the snap-fit ​​431 snaps into the surface of the connector 42 and the outlet of the hydrocyclone body 2. The other end of the snap-fit ​​431 is fixed by a fastener 432.

[0030] The latch 431 of the snap-fit ​​assembly 43 is opened and closed by a hinge at one end. When in use, the inner side of the latch 431 is snapped into the connection position between the connector 42 and the discharge port of the hydrocyclone body 2, and then locked by the fastener 432 at the other end, thereby firmly fixing the connector 42 and the discharge port. When disassembling, the latch 431 can be opened by loosening the fastener 432 (the engagement of the bolt and nut) to achieve quick separation.

[0031] The engagement of the buckle 431 and the fastener 432 (the combination of bolts and nuts) not only ensures the firmness of the connection between the connector 42 and the discharge port, preventing loosening due to vibration during the screening process, but also simplifies the disassembly and assembly process of the telescopic mechanism 4, making it easier to maintain and replace the telescopic tube 41 or the connector 42 in the future, and reducing the difficulty of operation.

[0032] The flow deflector 44 is flared and positioned above the collection box 3;

[0033] The trumpet-shaped flow guide 44 is located above the collection box 3. Its small-diameter end receives the aluminum particles discharged from the telescopic tube 41. Through the gradually enlarging structure, the aluminum particles are guided to the large-diameter end and finally fall into the collection box 3.

[0034] The trumpet-shaped structure expands the receiving range of aluminum particles, allowing them to be concentrated and guided, thereby reducing aluminum particle splashing, further reducing material loss, and improving collection efficiency.

[0035] The collection box 3 is fixedly connected to the two sides of the sliding rod 5. The front of the bottom of the mounting frame 1 is provided with a sliding groove 6 corresponding to the sliding rod 5. The sliding rod 5 slides in the sliding groove 6 and is engaged with the back of the bottom of the mounting frame 1.

[0036] The sliding rods 5 on both sides of the collection box 3 can slide along the sliding groove 6 at the bottom of the mounting frame 1 to realize the pull-out movement of the collection box 3. When the collection box 3 slides to the preset position, the sliding rods 5 are engaged with the bottom back of the mounting frame 1 to fix the collection box 3 below the corresponding discharge port.

[0037] The cooperation between the slide bar 5 and the slide groove 6 makes it easier to pick up and put down the collection box 3, facilitates the quick emptying of the collected aluminum particles, reduces downtime, and the back snap-fit ​​ensures that the collection box 3 is stably positioned during operation, ensuring that the aluminum particles can fall accurately into the box.

[0038] The bottom of the mounting bracket 1 is fixedly connected with support legs at equal intervals, and the bottom of the support legs is glued with rubber pads 7.

[0039] The support legs at the bottom of the mounting bracket 1 are evenly distributed to share the weight of the device and ensure the overall stability. The rubber pads 7 at the bottom of the support legs increase the friction with the ground and buffer the vibration generated during the operation of the device.

[0040] Equally spaced support legs ensure even force distribution when the device is placed, preventing tilting due to center of gravity shift and enhancing structural stability. Rubber pads 7 reduce the impact of device vibration on the ground, protecting the ground from damage, while also reducing noise generated by vibration, improving the workshop working environment, and reducing the impact of vibration on screening accuracy.

[0041] In practical use, first place the multi-stage cyclone aluminum particle screening device stably through the support legs that are evenly distributed at the bottom. The rubber pads 7 at the bottom of the support legs can reduce operating vibration and noise and ensure overall stability. Before operation, according to the specifications of the collection box 3, adjust the length of the telescopic tube 41 of the telescopic mechanism 4 to match the height of the collection box 3. The upper end of the telescopic tube 41 is connected to the discharge port of the cyclone body 2 through the connector 42. The connection is fixed by the snap-fit ​​component 43 (one end of the snap-fit ​​431 is hinged and the other end is locked by bolts and nuts) to ensure a firm connection. Then push the sliding rods 5 on both sides of the collection box 3 into the bottom sliding groove 6 of the mounting frame 1 so that the sliding rods 5 are snapped and fixed to the back of the mounting frame 1, so that the horn-shaped guide shroud 44 (small diameter connected to the telescopic tube 41, large diameter facing the collection box 3) is accurately positioned above the collection box 3.

[0042] After starting the multi-stage hydrocyclone aluminum particle screening device, the aluminum particles enter the hydrocyclone body 2. Under the action of centrifugal sedimentation and fluid dynamics, the material enters in a tangential direction to generate a three-dimensional elliptical strong rotational shear turbulence. Due to the large centrifugal force, the coarse particles move downward along the device wall and enter the corresponding telescopic mechanism 4 through the bottom outlet. The fine particles have a small centrifugal force and move towards the central axis. They move upward with the internal vortex and enter the upper hydrocyclone body 2 through the overflow pipe, thus realizing multi-stage progressive screening.

[0043] The screened aluminum particles are discharged through the telescopic tube 41 and guided into the collection box 3 by the horn-shaped guide hood 44. Even if there is a slight misalignment between the telescopic tube 41 and the collection box 3, the guide hood 44 can expand the receiving range and reduce splash loss. When the collection box 3 is full, the locking mechanism is released and the collection box 3 is removed. The cooperation between the slide rod 5 and the slide groove 6 makes it easy to pull out. After emptying, it can be pushed back into the locking mechanism for continued use. The whole process does not require an additional platform or pipeline, adapts to different production scenarios, and improves screening efficiency and flexible production capabilities.
