Description

Technical Field

[0001] This utility model relates to the field of magnetic separation technology, and more specifically, to a slag magnetic separation device with automatic cleaning function. Background Technology

[0002] In industries such as metallurgy and chemical engineering, slag treatment and resource recovery are crucial processes; magnetic separation technology, as an efficient metal separation method, is often used to recover ferromagnetic materials from slag.

[0003] Utility model patent CN214536195U discloses a magnetic separation iron removal device for high-temperature rotary kiln slag of hazardous waste. It includes: a hopper with a discharge port at its lower end; a conveyor belt with a closed-loop structure, the beginning and end of the conveyor belt's transport stroke connecting to the discharge port and the slag container, respectively; and a magnetic attraction assembly including an iron unloading belt and an electromagnet, the iron unloading belt forming a closed-loop structure around the electromagnet, and the iron unloading belt being located above the conveyor belt.

[0004] Although this invention enables the ferromagnetic components in the slag conveyed on the conveyor belt to be adsorbed onto the unloading belt, and the ferromagnetic components to be separated by centrifugal force through the rotation of the unloading belt, during the magnetic separation process, iron filings are easily adsorbed on the surface of the magnetic separation conveyor belt, requiring frequent shutdowns for manual cleaning, resulting in low equipment operating efficiency and increased labor costs.

[0019] These two settings can level the accumulated slag through the lifting plate, control the thickness of the slag accumulation, avoid the unstable adsorption effect of the magnetic separation conveyor belt on iron filings due to uneven slag thickness, ensure uniform material distribution, and improve magnetic separation accuracy.

[0040] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] Please see Figures 1-5 The present invention provides the following technical solution:

[0042] A slag magnetic separator with automatic cleaning function includes:

[0043] A transport mechanism 200 is installed on the top of a set of support plates 100. The transport mechanism 200 includes a transport conveyor belt 201 installed on the top of a set of support plates 100. The transport mechanism 200 is configured to move in a left-right direction.

[0044] A magnetic separation mechanism 600 is installed on the top of a set of vertical plates 500. The magnetic separation mechanism 600 is installed above the transport mechanism 200 and above the middle of the transport mechanism 200. The two are installed in different directions. The installation direction of the magnetic separation mechanism 600 is front and back. The magnetic separation mechanism 600 includes an isolation transport belt 601 installed on the top of a set of vertical plates 500 and two mounting plates 603. A magnetic separation transport belt 604 is installed between the two mounting plates 603. Several magnets are fixed on the surface of the magnetic separation transport belt 604. The magnetic separation transport belt 604 is located inside the isolation transport belt 601.

[0045] The cleaning mechanism 800 is installed at the rear end of the two mounting plates 603 and the two support plates 100 on the right end. The cleaning mechanism 800 includes a conveying cleaning roller 801 and a magnetic separation cleaning roller 803. The conveying cleaning roller 801 is rotatably connected between the top ends of the two support plates 100 on the right end. The rotation direction of the conveying cleaning roller 801 is the same as the movement direction of the conveyor belt 201. The conveying cleaning roller 801 is used to sweep the slag into the slag collection box 300 to prevent the slag from falling to the ground along the conveyor belt 201. The magnetic separation cleaning roller 803 is rotatably connected between the rear ends of the two mounting plates 603. The rotation direction of the magnetic separation cleaning roller 803 is opposite to the movement direction of the isolation conveyor belt 601. It is used to sweep the iron filings attached to the isolation conveyor belt 601 into the iron filings collection box 700, so that the device does not need to be stopped frequently for manual cleaning, realizing continuous magnetic separation operation and improving magnetic separation efficiency.

[0046] In this embodiment, please refer to Figures 1-3 The transport mechanism 200 also includes a transport motor 202 fixed on one of the support plates 100. The output shaft of the transport motor 202 is coaxially connected to the drive roller of the transport conveyor belt 201. The transport motor 202 serves as a power source to drive the transport conveyor belt 201.

[0047] In this embodiment, please refer to Figure 1 and Figure 2 It also includes a slag collection box 300 and an iron filings collection box 700. The slag collection box 300 is located at the right end of the conveyor belt 201, and the iron filings collection box 700 is located at the rear end of the magnetic separation conveyor belt 604, so that the slag and iron filings separated by magnetic separation can fall into the corresponding collection boxes automatically, which facilitates centralized processing and recycling, reduces the amount of manual collection work, and keeps the working environment clean.

[0048] In this embodiment, please refer to Figures 1-5 The magnetic separation mechanism 600 also includes a drive motor 602 fixed on one of the vertical plates 500 and a control motor 605 fixed on one of the mounting plates 603. The output shaft of the drive motor 602 is coaxially connected to the isolation conveyor belt 601, so that the isolation conveyor belt 601 and the magnetic separation conveyor belt 604 can be driven by independent motors respectively. The output shaft of the control motor 605 is coaxially connected to the drive roller of the magnetic separation conveyor belt 604. The magnetic separation conveyor belt 604 is used to provide magnetic force to attract iron filings, and the isolation conveyor belt 601 is used to isolate iron filings and provide a path for the transport of iron filings.

[0049] In this embodiment, please refer to Figures 1-3 It also includes a leveling mechanism 400, which includes two baffles 401 fixed between the tops of a set of support plates 100. A lifting plate 402 is slidably connected between the two baffles 401 near the left end, which can level the piled slag as needed to ensure uniform material distribution.

[0050] A slider 403 is fixed between the middle of the front and rear ends of the lifting plate 402. A groove is provided on the baffle 401 that corresponds to the position and size of the slider 403 on the same side. A horizontal plate 404 is also fixed on the top surface of the two baffles 401. A lead screw 405 is rotatably connected to the middle of the horizontal plate 404. The bottom end of the lead screw 405 is threaded to the lifting plate 402. A handwheel 406 is fixed to the top of the lead screw 405, so that the operator can manually adjust the height of the lifting plate 402 according to actual needs, flexibly control the accumulation thickness of slag on the conveyor belt 201. The operation is simple and the adjustment accuracy is high, which further improves the adsorption efficiency and recovery rate of iron filings by the magnetic separation conveyor belt 604.

[0051] In this embodiment, please refer to Figures 1-5 The cleaning mechanism 800 also includes two meshing gears 802. The two gears 802 are coaxially connected to the output shafts of the conveying cleaning roller 801 and the conveying motor 202, respectively. This allows the conveying cleaning roller 801 to be driven by the gears 802 and rotate directly using the power of the conveying motor 202. No additional drive device is required, which simplifies the structure and reduces energy consumption. At the same time, it ensures that the conveying cleaning roller 801 and the conveyor belt 201 operate synchronously to clean the slag in a timely manner.

[0052] The cleaning mechanism 800 also includes a belt 804. The magnetic separation cleaning roller 803 is connected to the control motor 605 via the belt 804, so that the magnetic separation cleaning roller 803 can rotate with the power of the control motor 605, and synchronize with the operation of the magnetic separation conveyor belt 604 and the isolation conveyor belt 601. When the iron filings are attracted by the magnetic separation conveyor belt 604 and move to the rear end with it, the magnetic separation cleaning roller 803 promptly sweeps the iron filings to the iron filings collection box 700, ensuring the continuity and effectiveness of the cleaning process, and further improving the automation level and working efficiency of the device.

[0053] Finally, it should be noted that the components involved in this utility model, such as the transport motor 202, drive motor 602, and control motor 605, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0054] When using the slag magnetic separator with automatic cleaning function, the slag to be processed is placed at the left end of the conveyor belt 201. The conveyor motor 202 is started, which drives the conveyor belt 201 to transport the slag to the right in the left-right direction. The slag moves along the conveyor belt. When it passes the leveling mechanism 400, the handwheel 406 drives the screw 405 to rotate, so that the lifting plate 402 slides up and down along the slide groove on the baffle 401, thereby adjusting the height of the lifting plate 402, leveling the accumulated slag, controlling the uniform thickness of the slag accumulation on the conveyor belt, and ensuring the stable adsorption effect of the subsequent magnetic separation conveyor belt 604 on iron filings.

[0055] Drive motor 602 and control motor 605 start respectively, driving isolation conveyor belt 601 to run in the front-to-back direction. Magnetic separation conveyor belt 604 rotates between two mounting plates 603. The magnets on its surface generate a magnetic field. When the slag on the conveyor belt moves to below the magnetic separation mechanism 600, the iron filings in the slag are attracted to the isolation conveyor belt 601 under the magnetic field of the magnets on the surface of the magnetic separation conveyor belt 604. As the magnetic separation conveyor belt 604 and the isolation conveyor belt 601 rotate, they move backward. Since the length of the isolation conveyor belt 601 is greater than the length of the magnetic separation conveyor belt 604, when the iron filings are at the rear end of the isolation conveyor belt 601, the magnetic field effect on the magnetic separation conveyor belt 604 weakens, and the iron filings are obliquely thrown into the iron filings collection box 700. The slag on the conveyor belt 201 enters the slag collection box 300.

[0056] The conveyor belt 201 transports non-ferromagnetic slag to the right end. At this time, the conveyor cleaning roller 801 rotates synchronously under the transmission of the conveyor motor 202 through the gear 802, and the rotation direction is the same as the movement direction of the conveyor belt 201. The conveyor cleaning roller 801 sweeps the slag on the conveyor belt into the slag collection box 300 set at the right end of the conveyor belt, completing the cleaning and collection of the slag. The iron filings adsorbed on the isolation conveyor belt 601 rotate to the rear end with the magnetic separation conveyor belt 604. The isolation conveyor belt 601 runs in the front-back direction. The magnetic separation cleaning roller 803 is driven by the belt 804 and the control motor 605 and rotates, and the rotation direction is opposite to the movement direction of the isolation conveyor belt 601. The magnetic separation cleaning roller 803 sweeps the iron filings attached to the isolation conveyor belt 601 into the iron filings collection box 700, completing the cleaning and collection of the iron filings.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
