Description

Technical Field

[0001] This utility model relates to the field of aluminum ash slag fine powder sorting technology, and more specifically, to an aluminum ash slag fine powder sorting device with multi-stage screening. Background Technology

[0002] Aluminum slag refers to the waste residue generated during the production and processing of aluminum. It is usually a byproduct of aluminum smelting, aluminum alloy production, or aluminum processing. It is mainly composed of aluminum oxide, iron oxide, silicon oxide, etc., and also contains small amounts of other metal oxides and impurities. Aluminum slag usually needs to be treated and disposed of to reduce its environmental impact. The common disposal method is recycling. In the recycling process, aluminum slag of different specifications needs to be screened and classified at multiple levels.

[0003] Common multi-stage screening devices for aluminum ash slag fine powder can only perform multi-stage screening of aluminum ash slag fine powder, but lack the function of adaptive material receiving. In practical applications, multi-stage screening requires the use of multiple screening plates with different mesh sizes to screen aluminum ash slag fine powder. Depending on the actual processing requirements, screening layers need to be added, which leads to an increase in the height of the multi-stage screening structure. As the height increases, it becomes difficult for the material discharged after screening to be received by the container. As the material falls from a height into the container, it will scatter everywhere, ultimately causing material loss.

[0004] In summary, to reduce processing costs, it is necessary to address the issue of material loss, ensuring that materials discharged from a height can directly fall into the corresponding containers for storage. Utility Model Content

[0005] The multi-stage screening device for aluminum ash slag fine powder separation provided by this utility model aims to solve the following problem: multi-stage screening of aluminum ash slag requires multiple mesh screens, which increases the height of the structure, making it difficult for the material to be received by the container at higher levels, and the material is prone to scattering during the falling process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage aluminum ash slag fine powder sorting device, including a positioning frame, a power mechanism on the positioning frame, an installation plate on the power mechanism, the output end of the power mechanism connected to the installation plate, multiple sorting cylinders above the installation plate, a discharge box on the outside of the sorting cylinders, an external threaded connector at the lower end of the discharge box, multiple telescopic throats on the upper end of the positioning frame, an internal threaded connector at the end of the telescopic throats away from the positioning frame, and a combination mechanism on the sorting cylinders.

[0007] In a preferred embodiment, the assembly mechanism is used to connect multiple sorting cylinders and to screen the aluminum ash slag fine powder. The assembly mechanism includes a connecting component and a screening component. The connecting component is used to fix the multiple sorting cylinders together, and the screening component is used to screen the aluminum ash slag fine powder.

[0008] In a preferred embodiment, the connecting assembly includes a lower flange installed at the lower end of the sorting cylinder and an upper flange installed at the upper end of the sorting cylinder. The lower flange of the sorting cylinder located at the upper end of the mounting plate is fixedly connected to the mounting plate, and multiple sorting cylinders are fixedly connected to each other through the lower flange of one and the upper flange of another.

[0009] In a preferred embodiment, the screening assembly includes a sorting plate installed inside the sorting cylinder and a guide plate installed inside the sorting cylinder.

[0010] In a preferred embodiment, a power mechanism is used to provide vibration force to the entire device. The power mechanism includes a movable component and a vibration component. The movable component is used to provide a certain offset space and maintain the stability of the device when it vibrates. The vibration component is used to vibrate the entire device.

[0011] In a preferred embodiment, the movable component includes a fixed cylinder mounted on the upper end of the positioning frame and a plurality of springs mounted on the upper end of the fixed cylinder.

[0012] In a preferred embodiment, the vibration assembly includes a plurality of limiting blocks mounted on the lower end of the mounting plate and a vibration motor mounted on the lower end of the mounting plate, with the limiting blocks inserted into the interior of the spring.

[0013] In a preferred embodiment, the positioning frame has multiple placement cavities inside, and a receiving box is provided inside each placement cavity.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention employs a design that allows for the connection of a retractable throat to the discharge ports of different screening layers, creating a highly adaptive, sealed discharge channel. This key structure can dynamically adjust its length according to the actual position of different screening layers, ensuring that regardless of the height to which the sorting cylinders are stacked, the material output from each discharge port can be seamlessly and vertically guided and transported to the corresponding receiving box within the positioning frame below. This completely avoids the problem of scattering and loss caused by materials falling freely from a height, significantly improves the recycling rate of aluminum ash slag powder, and effectively reduces the environmental pollution risk caused by dust diffusion.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 5 A multi-stage aluminum ash slag fine powder sorting device includes a positioning frame 1, a power mechanism on the positioning frame 1, an mounting plate 11 on the power mechanism, the output end of the power mechanism being connected to the mounting plate 11, multiple sorting cylinders 12 above the mounting plate 11, a discharge box 13 on the outside of the sorting cylinder 12, an external threaded connector 14 on the lower end of the discharge box 13, multiple telescopic throats 15 on the upper end of the positioning frame 1, an internal threaded connector 16 on the end of the telescopic throat 15 away from the positioning frame 1, and a combination mechanism on the sorting cylinder 12.

[0024] It should be noted that the positioning frame 1 serves as the basic support structure of the device, ensuring overall stability; the power mechanism drives the mounting plate 11 to vibrate, which in turn drives the sorting cylinder 12 to perform screening operations; the discharge box 13 is used to output the screened material; the telescopic throat 15 is stretched until the inner threaded connector 16 moves to the position of the outer threaded connector 14; the outer threaded connector 14 and the inner threaded connector 16 of the telescopic throat 15 are connected by threads to form a telescopic and sealed discharge channel; the length of the telescopic throat 15 can be adjusted according to the height of the sorting cylinder 12 to ensure that the material is always transported along a closed path.

[0025] It is worth noting that the design of the telescopic throat 15 solves the problem of material scattering caused by falling from a height when the screening layers are increased. Its telescopicity allows the discharge port height to adapt to the number of stacked layers of the sorting cylinder 12, and the material falls directly into the receiving box 18 of the placement chamber 17, avoiding loss and significantly improving the recovery rate.

[0026] Refer to the instruction manual appendix Figures 1 to 4 The combined mechanism is used to connect multiple sorting cylinders 12 and to screen the fine aluminum ash powder. The combined mechanism includes a connecting component and a screening component. The connecting component is used to fix the multiple sorting cylinders 12 together, and the screening component is used to screen the fine aluminum ash powder.

[0027] It should be noted that the combined mechanism has both structural connection and screening functions. The connecting components are mechanically fixed to ensure the vertical stacking reliability of the multi-stage sorting cylinders 12. The screening components achieve particle size classification of aluminum ash slag through the sorting plate 221, and the guide plate 222 guides the material flow to the discharge box 13.

[0028] Refer to the instruction manual appendix Figure 4 The connecting assembly includes a lower flange 211 installed at the lower end of the sorting cylinder 12 and an upper flange 212 installed at the upper end of the sorting cylinder 12. The lower flange 211 of the sorting cylinder 12 located at the upper end of the mounting plate 11 is fixedly connected to the mounting plate 11. Multiple sorting cylinders 12 are fixedly connected to each other through the lower flange 211 of one and the upper flange 212 of the other.

[0029] It should be noted that the lower flange 211 and the upper flange 212 are connected to the sorting cylinder 12 by bolt fastening. The bottom cylinder is fixed to the mounting plate 11 by the lower flange 211 to form an integral vibration unit. The flange connection surface is provided with a sealing gasket to prevent dust leakage.

[0030] Refer to the instruction manual appendix Figure 4 The screening assembly includes a sorting plate 221 installed inside the sorting cylinder 12 and a guide plate 222 installed inside the sorting cylinder 12.

[0031] It should be noted that the sorting plate 221 is a replaceable screen. Different sorting cylinders 12 are equipped with sorting plates 221 of different mesh sizes to achieve multi-stage screening. The guide plate 222 is installed at an inclination on the inner wall of the sorting cylinder 12 to guide the material to be discharged to the discharge box 13.

[0032] Refer to the instruction manual appendix Figures 1 to 3 The power mechanism is used to provide vibration force to the entire device. The power mechanism includes a moving component and a vibration component. The moving component is used to provide a certain offset space and maintain the stability of the device when it vibrates. The vibration component is used to vibrate the entire device.

[0033] It should be noted that the vibration component generates high-frequency micro-amplitude vibration, which enables the aluminum ash slag to be efficiently separated on the sorting plate 221. The moving component absorbs the vibration impact through elastic deformation, avoiding rigid transmission that could cause deformation of the positioning frame 1.

[0034] It is worth noting that the synergistic effect of the two components improves screening efficiency while reducing mechanical fatigue wear. The vibration parameters can be adjusted by the vibration motor 322 to adapt to aluminum ash slag with different humidity or viscosity.

[0035] Refer to the instruction manual appendix Figure 3 The movable components include a fixed cylinder 311 mounted on the upper end of the positioning frame 1 and multiple springs 312 mounted on the upper end of the fixed cylinder 311.

[0036] It should be noted that the spring 312 is fixed to the upper end of the fixed cylinder 311, and the limiting block 321 is inserted into it to form a double constraint. This not only facilitates the installation and removal of the mounting plate 11, but also limits the position of the mounting plate 11.

[0037] Refer to the instruction manual appendix Figure 3 The vibration assembly includes multiple limiting blocks 321 mounted on the lower end of the mounting plate 11 and a vibration motor 322 mounted on the lower end of the mounting plate 11. The limiting blocks 321 are inserted into the interior of the spring 312.

[0038] It should be noted that the vibration motor 322 is arranged at the bottom of the mounting plate 11 to generate a uniform excitation force, which drives multiple sorting plates 221 with different mesh sizes to vibrate synchronously.

[0039] Refer to the instruction manual appendix Figure 5 The positioning frame 1 has multiple placement cavities 17 inside, and a receiving box 18 is installed inside the placement cavity 17.

[0040] It should be noted that the size of the placement cavity 17 matches the receiving box 18, and the top of the box is open and aligned with the outlet of the telescopic throat 15, so that the material can be discharged into the corresponding receiving box 18 through the telescopic throat 15.

[0041] Working principle: Fine aluminum ash slag powder is fed into the top sorting cylinder 12. A vibrating motor 322 drives the mounting plate 11 to generate high-frequency vibration, causing all sorting cylinders 12 to vibrate synchronously. Inside the sorting cylinder 12, the aluminum ash slag is screened stage by stage by sorting plates 221. The upper sorting plates 221 have a larger mesh size, intercepting coarse particles. The lower sorting plates 221 have progressively smaller mesh sizes, separating fine powders of different fineness. During the screening process, guide plates 222 guide substandard particles to the discharge box 13 of that layer, while qualified fine powder falls into the next stage for further screening. The material discharged from each layer passes through the discharge box 13 below... When the external threaded connector 14 is discharged, the internal threaded connector 16 of the telescopic throat 15 is threadedly connected to the external threaded connector 14 to form a sealed channel. The telescopic throat 15 adapts to the stacking height of the sorting cylinder 12 to ensure that the material is always vertically transported through the sealed pipe to the receiving box 18 of the built-in discharge cavity 17 of the positioning frame 1, avoiding the scattering and loss of material when it falls from a height. In the power mechanism, the spring 312 and the limit block 321 work together to buffer the vibration impact and maintain the stability of the device. After the vibration ends, the aluminum ash slag fine powder of each level is accurately sorted and stored in the corresponding receiving box 18.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
