Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a dust removal vibrating screen for magnetic separators. Background Technology

[0002] Magnetic separators are screening devices used to remove iron powder and other pollutants from recycled powdery materials. After the slurry flows into the tank through the feed box, the mineral particles enter the feed area of ​​the tank in a loose state under the action of the water flow from the feed spray pipe. Under the action of the magnetic field, the magnetic mineral particles undergo magnetic aggregation to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are attracted to the cylinder by the magnetic force in the slurry and move towards the magnetic pole. Since the polarity of the magnetic poles is alternately arranged along the rotation direction of the cylinder and remains stationary during operation, the "magnetic clusters" or "magnetic chains" generate a magnetic stirring phenomenon due to the alternating magnetic poles as the cylinder rotates. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the agitation. The "magnetic clusters" or "magnetic chains" that are finally attracted to the surface of the cylinder are the concentrate.

[0003] Since magnetic separators are used to screen small-volume powdery slurries, they are difficult to effectively screen larger particles. Therefore, magnetic separators need to be used in conjunction with screening devices to remove large minerals, and then the screened minerals are subjected to magnetic separation. For example, Chinese Patent Publication No. CN221638426U discloses "a dust removal vibrating screen for a magnetic separator", which, by having a screening device, can remove the dust contained in the sand and gravel during the screening process, preventing the magnetic particles in the sand and gravel from enveloping the dust and adhering to the surface of the magnetic separator, mixing in the magnets, and affecting the overall quality of the magnets.

[0004] However, in actual use, the dust generated by the dust removal vibrating screen is directly discharged into the environment, which not only pollutes the environment but also affects the health of the operators. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the direct discharge of dust generated by dust-collecting vibrating screens into the environment, which not only pollutes the environment but also affects the health of operators. Therefore, this invention proposes a dust-collecting vibrating screen for magnetic separators.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a dust removal vibrating screen for a magnetic separator, including a machine body, a base at the bottom of the machine body, multiple springs fixedly mounted on the base, multiple connecting seats cooperating with the springs on the machine body, a screen inside the machine body, the screen being connected to the machine body via a connecting assembly, a waste discharge port and a material discharge port on the machine body, a funnel fixedly mounted inside the material discharge port, a vibrating motor on one side of the machine body, and a dust removal device on the machine body.

[0008] Furthermore, the connecting assembly includes an extension plate disposed on the screen, and the machine body is provided with a slot that mates with the extension plate. The slot and the extension plate are provided with through holes, and positioning bolts are disposed in the through holes.

[0009] Furthermore, the dust removal device has extension pipes on both sides, and the machine body has air guide holes that communicate with the extension pipes.

[0010] Furthermore, the dust removal device is equipped with a filter screen and an exhaust fan. The exhaust fan is located inside the filter screen, and a mounting plate is fixedly installed inside the filter screen. A dual-axis motor that is poweredly connected to the exhaust fan is installed on the mounting plate.

[0011] Furthermore, the dust removal device has a through groove, a collection box is movably inserted into the through groove, a cleaning brush is provided on the filter screen, and one output shaft of the dual-axis motor is poweredly connected to the cleaning brush and rotatably connected to the machine body.

[0012] Furthermore, extension brushes are provided on both sides of the cleaning brush, a guide rail is fixedly provided on the filter screen, and the extension brush has a guide groove corresponding to the guide rail.

[0013] The dust removal vibrating screen for magnetic separators proposed in this utility model has the following advantages:

[0014] In this utility model, by setting an extension plate on the screen and inserting it into the machine body, the screen can be disassembled for cleaning and maintenance, and different specifications of screens can also be replaced, thereby screening out minerals of the required specifications.

[0015] Secondly, in this utility model, a dust removal device is set up to absorb the dust generated by the vibrating screen, and the dust is filtered out through a filter screen to prevent the dust from being directly discharged into the environment and polluting the environment.
