Description

Technical Field

[0001] This invention belongs to the field of electrolytic aluminum screening technology, specifically relating to a magnetic separation and screening device for electrolytic aluminum waste residue. Background Technology

[0002] In the treatment of electrolytic aluminum waste (mainly referring to the slag from major electrolytic cell overhauls, primarily composed of waste cathode carbon blocks), magnetic separation and screening is a crucial pretreatment and resource recovery step. It is mainly used to separate ferromagnetic impurities (such as steel bars, bolts, iron filings, etc.) and recover metallic aluminum particles. Its core objective is:

[0003] 1. Removes ferromagnetic impurities: Protects subsequent processing equipment (such as crushers and mills) from damage and extends equipment life.

[0004] 2. Recycling aluminum: Separating aluminum particles mixed in with the waste residue to achieve resource recycling and improve economic efficiency.

[0005] 3. Preparing for subsequent processing: Screening can classify materials, allowing materials of different particle sizes to enter the most suitable processing flow. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic separation and screening device for electrolytic aluminum waste residue, which can remove impurities such as iron that can be adsorbed by magnetism from the electrolytic aluminum waste residue and can quickly screen the electrolytic aluminum waste residue.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A magnetic separation and screening device for electrolytic aluminum waste includes a first conveyor belt for conveying electrolytic aluminum waste and a second conveyor belt for conveying the magnetically separated waste. A magnetic separation mechanism is arranged above the first and second conveyor belts and is rotatably connected to a support. A scraping mechanism is arranged on the lower end face of the magnetic separation mechanism and is located on one side of the second conveyor belt. The magnetic separation mechanism includes a magnetic separation disk with slots evenly distributed inside. Permanent magnets are placed in the slots, and the permanent magnets are covered with a cover plate.

[0009] In a preferred embodiment, a receiving tray is provided above the second conveyor belt for receiving the slag scraped off the magnetic separator by the scraping mechanism.

[0010] In a preferred embodiment, a drive motor is connected to the top of the magnetic separation mechanism, and the outer casing of the drive motor is fixedly connected to the bracket.

[0011] In a preferred embodiment, the scraping mechanism includes a mounting frame, in which a scraper is installed. The upper end of the scraper is fitted against the lower end face of the cover plate, and the mounting frame and the scraper are detachable.

[0012] In a preferred embodiment, a telescopic rod is connected to the outer side of the mounting bracket, and the upper end of the telescopic rod is fixedly mounted on the bracket.

[0013] In a preferred embodiment, a guide rod is also connected to the outer side of the mounting bracket, and the guide rod is slidably connected to the bracket.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model uses a conveyor belt to transport electrolytic aluminum waste residue. Waste residue containing iron and other magnetically adsorbable materials is attracted by the magnetic force generated when it passes through the magnetic separation mechanism. Then, as the magnetic separation mechanism rotates, the adsorbed waste residue is turned to the upper end of the second conveyor belt. When the magnetic separation mechanism rotates above the second conveyor belt, the adsorbed waste residue is scraped off by the scraping mechanism and falls onto the second conveyor belt, thereby achieving the purpose of screening the waste residue.

[0016] This utility model makes the magnetic separation mechanism rotatable, which facilitates the transfer of the adsorbed waste residue. The waste residue is adsorbed and picked out from conveyor belt one, and the selected waste residue is transferred to conveyor belt two for scraping by the rotation of the magnetic separation mechanism, making the selection of waste more convenient.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Please see the appendix Figure 1 and Figure 2 As shown, this utility model provides a magnetic separation and screening device for electrolytic aluminum waste slag, including a conveyor belt 1 for conveying electrolytic aluminum waste slag and a conveyor belt 2 for conveying the slag after magnetic separation. A magnetic separation mechanism 3 is arranged above the conveyor belt 1 and the conveyor belt 2. The magnetic separation mechanism 3 is rotatably connected to the support 4. A scraping mechanism 5 is arranged on the lower end face of the magnetic separation mechanism 3, and the scraping mechanism 5 is located on one side of the conveyor belt 2. The magnetic separation mechanism 3 includes a magnetic separation disk 31. Slots 32 are evenly opened in the magnetic separation disk 31. Permanent magnets 33 are placed in the slots 32. The permanent magnets 33 are covered with a cover plate 34.

[0028] During the screening process of electrolytic aluminum waste slag, conveyor belt 1 is used to transport the waste slag. When the waste slag is transported to the magnetic separation mechanism 3 by conveyor belt 1, if the waste slag contains substances that can be magnetically adsorbed, such as iron, the waste slag will be adsorbed onto the lower surface of the magnetic separation mechanism 3. During the magnetic separation process, the magnetic separation mechanism 3 rotates continuously on the support 4. Through the rotation of the magnetic separation mechanism 3, the adsorbed waste slag can be transferred from above the conveyor belt 1 to the conveyor belt 2. Then, when the waste slag reaches above the conveyor belt 2, the waste slag is scraped off from the magnetic separation mechanism 3 by the scraping mechanism 5 and falls onto the conveyor belt 2, thus completing the purpose of screening.

[0029] Please see Figure 4As shown, in this embodiment, the magnetic attraction of the magnetic separation mechanism 3 is generated by the permanent magnet 33. The permanent magnet 33 is installed in the slot 32 of the magnetic separation disk 31. The slot 32 can be used to position the permanent magnet 33 so that the permanent magnet 33 can be evenly placed in the magnetic separation disk 31. After the permanent magnet 33 is installed, it can be sealed with a cover plate 34 to prevent the permanent magnet 33 from falling off.

[0030] Above the conveyor belt 2, there is a receiving tray 21 for receiving the slag scraped off the magnetic separator 3 by the scraping mechanism 5;

[0031] In this application, the slag scraped off from the magnetic separator 3 by the scraping mechanism 5 first falls onto the receiving tray 21, and then slides off the receiving tray 21 onto the conveyor belt 2, which then transports it to the next process.

[0032] The top of the magnetic separation mechanism 3 is connected to a drive motor 35, and the outer casing of the drive motor 35 is fixedly connected to the bracket 4;

[0033] The rotation of the magnetic separator 3 is driven by the drive motor 35, and the control of the drive motor 35 is controlled by the control device. The control device's drive of the drive motor 35 is existing technology and will not be described in detail here.

[0034] Please see Figure 2 and Figure 3 As shown, the scraping mechanism 5 includes a mounting frame 51, in which a scraper 52 is installed. The upper end of the scraper 52 is fitted against the lower end face of the cover plate 34. The mounting frame 51 and the scraper 52 are detachable.

[0035] In this embodiment, the scraper 52 of the scraping mechanism 5 is mounted on the mounting frame 51 and fixed by bolts for easy disassembly and replacement. The scraper 52 contacts the cover plate 34 to scrape off the adsorbed slag. The scraper 52 can be made of rubber, which is wear-resistant and will not scratch the cover plate 34.

[0036] The outer side of the mounting bracket 51 is connected to a telescopic rod 53, and the upper end of the telescopic rod 53 is fixedly installed on the bracket 4.

[0037] Preferably, the extension and retraction of the telescopic rod 53 can drive the mounting frame 51 and the scraper 52 to move up and down, which facilitates the adjustment of the distance between the scraper 52 and the magnetic separation mechanism 3, thereby adjusting the tightness of the contact between the scraper 52 and the cover plate 34, and adjusting the scraping force of the scraper 52 on the surface of the cover plate 34.

[0038] A guide rod 54 is also connected to the outside of the mounting bracket 51, and the guide rod 54 is slidably connected to the bracket 4;

[0039] When the mounting bracket 51 and scraper 52 are moved up and down for adjustment, the guide rod 54 will slide up and down on the bracket 4. The connection between the guide rod 54 and the bracket 4 improves the stability of the mounting bracket 51 and scraper 52 during use.

[0040] The working principle of this utility model is as follows: During the screening process of electrolytic aluminum waste slag, conveyor belt 1 is used to transport the waste slag. When the waste slag is transported to the magnetic separation mechanism 3 by conveyor belt 1, if the waste slag contains substances that can be magnetically adsorbed, such as iron, the waste slag will be adsorbed onto the lower surface of the magnetic separation mechanism 3. During the magnetic separation process, the magnetic separation mechanism 3 rotates continuously on the support 4. Through the rotation of the magnetic separation mechanism 3, the adsorbed waste slag can be transferred from above the conveyor belt 1 to the conveyor belt 2. Then, when the waste slag reaches above the conveyor belt 2, the waste slag is scraped off from the magnetic separation mechanism 3 by the scraping mechanism 5 and falls onto the conveyor belt 2, thus completing the purpose of screening.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
