Description

Technical Field

[0001] This application relates to the field of material hanging and screening technology, and in particular to a stepped material hanging and screening mechanism. Background Technology

[0002] Screening discs are widely used in the mining and metallurgical industry, materials industry, and other fields. For example, in the screening of raw material strips for aluminum disc production, screening discs can separate out unsuitable sizes to meet different market demands for subsequent processing and use.

[0003] In the existing technology, the screening disc is driven by a motor for centrifugal separation. However, due to the single-layer moving pipe, the screening efficiency is generally low. Therefore, this application proposes a stepped hanging screening mechanism that can improve the screening efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a stepped material hanging and screening mechanism to solve the technical problems in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a stepped material hanging screening mechanism, including a screening disc and an inner spiral stepped channel fixedly connected to the inner side of the screening disc, a housing rotatably provided on the outer side of the screening disc, a straight conveying channel provided on one side of the screening disc, the housing and the straight conveying channel being fixedly connected, a base provided at the bottom of the screening disc, and a driving device for driving the screening disc provided on the base.

[0006] Furthermore, the inner spiral stepped channel is provided with a primary screening trough and a secondary screening trough.

[0007] By adopting the above technical solution, the inner spiral stepped channel in this application has only one width for the raw material. The driving device drives the screening disc to rotate, and the raw material will first move through the inner spiral stepped channel. When it passes the position of the first-level screening trough, it will fall back into the screening disc. Of course, it is also possible that it will not fall into the first-level screening trough. Therefore, as it continues to move, it will fall onto the next step when it passes the step and approach the second-level screening trough. When the raw material does not meet the size requirements, it will fall into the second-level screening trough due to the steps and return to the screening disc.

[0008] Furthermore, the driving device includes a bracket fixedly connected to the base, on which a drive motor is fixedly mounted, and the output end of the drive motor is fixedly connected to the screening disc.

[0009] By adopting the above technical solution, the drive motor drives the screening disc to rotate, and the raw material strips are dispersed to the surrounding area of ​​the screening disc by centrifugal force.

[0010] Furthermore, the secondary screening tank is provided with an inwardly inclined groove on the side of the primary screening tank that is close to the secondary screening tank, which is located in the inner spiral stepped channel.

[0011] By adopting the above technical solution, it can be ensured that raw material bars of normal size that fall into the steps are not likely to fall back into the screening disc.

[0012] Furthermore, an outlet groove is provided in the middle of the secondary screening tank, and an abutment block is fixedly connected to the screening disc on one side of the outlet groove. An abutment groove is provided at the bottom of the abutment block.

[0013] By adopting the above technical solution, in order to keep the raw materials in a consistent posture during transportation to the straight conveyor, when the raw materials move to the outlet trough, one side of the raw materials will be embedded in the contact trough, while the raw materials in other postures will fall into the outlet trough and into the screening disc.

[0014] Furthermore, a movable frame is fixedly installed at the upper end of the straight transport channel, and a transport trough for moving raw materials is opened in the middle of the movable frame.

[0015] By adopting the above technical solution, the raw materials after outer screening will enter the transport trough in the moving frame and wait for subsequent work.

[0016] Furthermore, the transport trough is provided with a smooth plate that is fixedly connected to the movable frame.

[0017] By adopting the above technical solution, the smooth plate is made of stainless steel, which ensures the normal movement of raw materials in the transport tank.

[0018] In summary, this application includes the following beneficial technical effects: The design of the internal spiral stepped channel allows the raw materials to move in an orderly manner during the screening process, and due to the presence of the steps, the raw materials can be effectively separated according to size when passing through the primary and secondary screening tanks. This design improves screening efficiency, making the screening process faster and more accurate. Through the setting of the primary and secondary screening tanks, this mechanism can achieve precise grading of raw materials. Raw materials of different sizes will be screened to different positions, thereby meeting the different particle size requirements of subsequent processing processes. The design of the internal spiral stepped channel helps reduce clogging during the screening process. Due to the presence of the steps, the raw materials will continuously change position during movement, thereby reducing the possibility of accumulation at the screening tank opening. This helps maintain the stable operation of the screening mechanism and extend its service life. The screening mechanism has a compact structural design and a small footprint. The rational layout of components such as the screening disc, internal spiral stepped channel, outer shell, and straight conveyor channel enables the entire mechanism to achieve efficient screening within a limited space. This helps reduce production costs and improve production efficiency. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Example, refer to Figures 1-3 A stepped material screening mechanism includes a screening disc 1 and an inner spiral stepped channel 12 fixedly connected to the inner side of the screening disc 1. A housing 11 is rotatably mounted on the outer side of the screening disc 1. A straight conveying channel 3 is provided on one side of the screening disc 1. The housing 11 and the straight conveying channel 3 are fixedly connected. A base 2 is provided at the bottom of the screening disc 1, and a driving device for driving the screening disc 1 is provided on the base 2. The inner spiral stepped channel 12 has a primary screening trough 13 and a secondary screening trough 14.

[0025] In this application, the inner spiral stepped channel 12 has only one width for raw material 4. The drive device drives the screening disc 1 to rotate, and the raw material 4 will first move through the inner spiral stepped channel 12. When it passes the position of the primary screening trough 13, it will fall back into the screening disc 1. Of course, it is also possible that it will not fall into the primary screening trough 13. Therefore, when it continues to move, it will fall onto the next step when it passes the step and approach the secondary screening trough 14. When it does not meet the requirements, the raw material 4 will fall into the secondary screening trough 14 due to the step and return to the screening disc 1.

[0026] In this embodiment, the driving device includes a bracket 21 fixedly connected to the base 2, and a drive motor 22 fixedly mounted on the bracket 21. The output end of the drive motor 22 is fixedly connected to the screening disc 1. The drive motor 22 drives the screening disc 1 to rotate, and disperses the four raw materials around the screening disc 1 through centrifugal force.

[0027] In this embodiment, the secondary screening tank 14 is provided with an inner inclined groove 16 on the side near the primary screening tank 13, which is located in the inner spiral stepped channel 12. This ensures that the four normally sized raw materials that fall into the stepped channel are less likely to fall back into the screening disc 1.

[0028] In this embodiment, an outlet trough 15 is provided in the middle of the secondary screening trough 14. An abutment block 17 is fixedly connected to the screening disc 1 on one side of the outlet trough 15, and an abutment groove 18 is provided at the bottom of the abutment block 17. In order to keep the raw material 4 in a consistent posture when it is transported to the straight conveyor 3, when the raw material 4 moves to the outlet trough 15, one side of the raw material 4 will be embedded in the abutment groove 18, while the raw material 4 in other postures will fall into the outlet trough 15 and into the screening disc 1.

[0029] In this embodiment, a movable frame 31 is fixedly installed at the upper end of the straight transport channel 3, and a transport trough 32 for the raw material 4 to move is opened in the middle of the movable frame 31. The raw material 4 after being screened on the outside will enter the transport trough 32 in the movable frame 31 to wait for subsequent work.

[0030] In this embodiment, a smooth plate is fixedly connected to the movable frame 31 in the transport trough 32. The smooth plate is made of stainless steel to ensure the normal movement of the raw material 4 in the transport trough 32.

[0031] The specific implementation process is as follows: Its structure comprises a screening disc 1, an inner spiral stepped channel 12, a shell 11, a linear conveyor channel 3, a base 2, and a drive device. The inner spiral stepped channel 12, fixedly connected to the inner side of the screening disc 1, is its core screening component. It has a primary screening trough 13 and a secondary screening trough 14, and the width of the inner spiral stepped channel 12 is only wide enough for one raw material 4 to pass through, ensuring the orderly movement of the raw material 4. The shell 11 is rotatably mounted on the outside of the screening disc 1 and fixedly connected to the linear conveyor channel 3, serving to protect the internal components and guide the flow of the raw material 4. The linear conveyor channel 3 is located on one side of the screening disc 1 and is used to receive the screened raw material 4 and transport it to subsequent processing stages. The base 2 supports the entire mechanism, ensuring stability. The drive device includes a bracket 21 fixedly connected to the base 2 and a drive motor 22. The output end of the drive motor 22 is fixedly connected to the screening disc 1, driving the screening disc 1 to rotate.

[0032] In terms of working principle, after the raw material 4 is fed into the screening disc 1, the drive motor 22 drives the screening disc 1 to rotate, and the raw material 4 is dispersed to the surrounding area of ​​the screening disc 1 by centrifugal force. When the raw material 4 moves on the inner spiral stepped channel 12, it will first pass through the primary screening trough 13. Raw materials 4 that do not meet the size requirements will fall into the screening disc 1. The raw materials 4 that do not fall into the primary screening trough 13 continue to move, fall to the next step after passing the steps and approach the secondary screening trough 14. Raw materials 4 that still do not meet the size requirements will fall into the secondary screening trough 14 and return to the screening disc 1. The raw materials 4 that meet the size requirements will move to the outlet trough 15 in the middle of the secondary screening trough 14, one side of which is embedded in the contact groove 18 set at the bottom of the contact block 17 to maintain a consistent posture, and then enter the transport trough 32 in the moving frame 31 of the straight transport channel 3 to wait for further processing.

[0033] The key design features of this device are significant. An inwardly inclined trough 16 is located on the side of the secondary screening trough 14 near the primary screening trough 13, ensuring that the four pieces of raw material of normal size are less likely to fall back into the screening disc 1. The coordinated design of the contact trough 18 and the outlet trough 15 ensures that the raw material 4 maintains a consistent posture when transported to the straight conveyor 3. The smooth plate in the conveyor trough 32 is made of stainless steel, reducing friction and wear and ensuring the normal movement of the raw material 4 within the conveyor trough 32.

[0034] During operation, the drive unit is first started, and after the power is connected, the drive motor 22 drives the screening disc 1 to rotate. Then, the raw material 4 is evenly fed into the screening disc 1. Under the action of centrifugal force, the raw material 4 is dispersed to the periphery of the screening disc 1 and the screening process begins. After screening through the primary and secondary screening tanks 14, the raw material 4 that does not meet the requirements falls into the screening disc 1, while the raw material 4 that meets the requirements enters the linear conveyor 3. Finally, the screened raw material 4 is collected in the conveyor trough 32 of the linear conveyor 3 for subsequent processing, such as collection, packaging, or further processing.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
