Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, and particularly relates to a feeding speed reducing mechanism for a magnetic separator. Background Art

[0002] A magnetic separator is a device used to separate magnetic substances in materials, and has a wide range of applications in many fields such as mining, metallurgy, environmental protection, and chemical industry.

[0003] Different types of magnetic separators are suitable for different application scenarios and material characteristics. Common types of magnetic separators include permanent magnet drum magnetic separators, wet magnetic separators, dry magnetic separators, high-gradient magnetic separators, etc. Each type has its unique structure and working principle to meet the needs of different users.

[0004] At present, after the existing magnetic separator pours the magnetized material into the feed hopper, it will quickly discharge from the outlet of the feed hopper. Often, due to the inability to adjust the feeding speed, the problem of incomplete magnetic separation occurs. For example, Chinese Patent CN 221433437 U discloses a rice magnetic separator, which includes a box body. A feed hopper is arranged at the top of the box body, and a number of magnetic separation units are arranged below the feed hopper. The magnetic separation unit includes two first feeding plates symmetrically arranged and inclined downward, and a strong magnetic roller I is arranged close to the upper surfaces of the two first feeding plates. A channel I is left between the lower ends of the two first feeding plates and the box body. A second feeding plate is arranged obliquely downward below the two first feeding plates, and a channel II is left between the lower ends of the two second feeding plates. Two third feeding plates symmetrically arranged and inclined downward are arranged below the two second feeding plates, and a strong magnetic roller II is arranged close to the upper surfaces of the two third feeding plates. A channel III is left between the lower ends of the two first feeding plates and the box body. The technical solution of this patent is that the feed hopper is directly connected to the magnetic separation unit and the feeding speed cannot be adjusted. Therefore, a feeding speed reducing mechanism for a magnetic separator is needed to adjust the feeding speed of the feed hopper so as to adaptively adjust and ensure the quality of the magnetic separation operation. Content of the Utility Model

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A feeding speed reducing mechanism for a magnetic separator includes an upper guide plate arranged obliquely downward. A step surface is arranged at the lower end of the upper guide plate, and a lower guide plate is connected to the lower end of the step surface. Side plates are arranged on the front and rear sides of the upper guide plate and the lower guide plate. A number of partition plates I arranged in the front-rear direction and parallel to each other are arranged on the upper surface of the lower part of the upper guide plate, dividing the upper guide plate into a number of feeding channels, and a material blocking mechanism is arranged at the lower end of each feeding channel.

[0007] Preferably, the material blocking mechanism includes an arc-shaped channel, which is bent and protruded toward the side away from the upper material guiding plate. A baffle is movably arranged in the arc-shaped channel. A notch is formed on the side of the arc-shaped channel away from the upper material guiding plate. A rack is arranged on the side of the baffle facing the notch and extends out of the notch.

[0008] Preferably, several feeding channels are evenly divided into several feeding units. A rotating shaft with the same number as the feeding units is arranged between the two side plates. Several rotating shafts are arranged in an arc along the trend of the arc-shaped channel. Gears are fixedly arranged on the rotating shafts. The gears in each feeding unit are arranged on different rotating shafts. A driving motor I is arranged at one end of the rotating shaft.

[0009] Preferably, a blanking port is arranged between the lower end of the arc-shaped channel and the step surface.

[0010] Preferably, the upper surface of the lower end of the baffle is flush with the upper surface of the step surface.

[0011] Preferably, a cover body is arranged on the upper part of the lower material guiding plate. Several driving motors II are arranged perpendicular to the upper surface of the cover body. The output ends of the driving motors II pass through the cover body and are connected to the scraping plate.

[0012] Preferably, a gap is left between the scraping plate and the upper surface of the lower material guiding plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By controlling the rotation of different numbers of driving motors I, the present utility model drives the gears to rotate, and the gears drive the baffle to open and close, so as to open different numbers of feeding channels, thereby controlling the amount of material entering the lower material guiding plate from the upper material guiding plate 1, controlling the blanking speed of the material, playing a role in slowing down, ensuring that the blanking speed of the material does not exceed the processing capacity of the magnetic separator, and guaranteeing the quality of magnetic separation. After the material enters the lower material guiding plate, the rotating scraping plate is used to evenly spread the material, further guaranteeing the quality of magnetic separation. In addition, by controlling the rotation speed of the driving motor II, the blanking speed of the material can also be controlled, thereby playing a role in slow speed adjustment.

[0022] As Figures 1 - 3 shown, in this embodiment, a slow-down mechanism for the blanking of a magnetic separator includes an upper material guiding plate 1 arranged obliquely downward. The upper end of the upper material guiding plate 1 is provided with a feeding port 2, the lower end of the upper material guiding plate 1 is provided with a stepped surface 3, the lower end of the stepped surface 3 is connected to a lower material guiding plate 4, side plates 5 are arranged on the front and rear sides of the upper material guiding plate 1 and the lower material guiding plate 4, and 8 partition plates 6 arranged in the front-rear direction and parallel to each other are arranged on the upper surface of the lower part of the upper material guiding plate 1, dividing the upper material guiding plate 1 into 9 feeding channels, and a material blocking mechanism is arranged at the lower end of each feeding channel.

[0023] In this embodiment, the material blocking mechanism includes an arc-shaped channel 7, which is bent and protruded toward the side away from the upper material guiding plate 1. A baffle 8 is movably arranged in the arc-shaped channel 7. There is a notch 9 on the side of the arc-shaped channel 7 away from the upper material guiding plate 1. A rack 17 is arranged on the side of the baffle 8 facing the notch 9, and the rack 17 extends out of the notch 9.

[0024] In this embodiment, the feeding channel is evenly divided into 3 groups of feeding units. There are rotating shafts 10 with the same number as the feeding units arranged between the two side plates 5. The three rotating shafts 10 are arranged in an arc along the direction of the arc-shaped channel 7. A gear 11 is fixedly arranged on each rotating shaft 10. The gears 11 in each feeding unit are arranged on different rotating shafts 10. One end of the rotating shaft 10 is provided with a driving motor 12.

[0025] In this embodiment, there is a blanking port 13 arranged between the lower end of the arc-shaped channel 7 and the step surface 3.

[0026] In this embodiment, the upper surface of the lower end of the baffle 8 is flush with the upper surface of the step surface 3.

[0027] In this embodiment, a cover 14 is arranged on the upper part of the lower material guiding plate 4. Two driving motors 15 are arranged perpendicular to the upper surface of the cover 14 on the upper surface of the cover 14. The output end of the driving motor 15 passes through the cover 14 and is connected to the scraping plate 16.
