Description

Technical Field

[0001] The invention relates to a screening device, in particular to a five-layer high-frequency fine screen for separating magnetite ores. Background Art

[0002] Magnetite refers to the ore of the oxide mineral magnetite, which belongs to the isometric crystal system. The crystals are octahedrons and dodecahedrons, with stripes on the crystal faces, and are mostly granular aggregates. It is iron black, or dark blue indigo, with black streaks, semi-metallic luster, opaque, without cleavage, uneven fracture, hardness of 5.5-6.5, density of 5.16-5.18g / cm3, with strong magnetism, brittle, odorless, tasteless, and often produced in igneous rocks and metamorphic rocks.

[0003] The screen of the five-layer high-frequency fine screen for magnetite ore separation in the prior art is not easy to replace and is not easy to use during work, so we propose a five-layer high-frequency fine screen for magnetite ore separation to solve the above problems. Summary of the invention

[0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] A five-layer high-frequency fine screen for magnetite ore sorting comprises a sorting machine body, wherein a screening feed port and an unscreened feed port are respectively arranged at the bottom of the sorting machine body, and the unscreened feed port is located on the right side of the screening feed port, an adjusting gear is movably mounted on the front inner wall of the sorting machine body, a rack is slidably mounted on the front inner wall of the sorting machine body, and there are two racks, the adjusting gear is respectively meshed with the two racks, and the ends of the two racks that are away from each other are fixedly connected with sprockets, and there are two sprockets, and the inner walls on both sides of the sorting machine body are There are two push rods in a sliding connection, the bottom of the push rod is rotatably connected to the top of the sprocket, the top of the screening discharge port is movably connected to a screening frame, and there are five screening frames, both side outer walls of the five screening frames are symmetrically fixed with sliders, and there are twenty sliders, both side inner walls of the sorting machine body are fixedly installed with slideways, and there are ten slideways, the sliders are slidably connected to the slideways, the front inner wall of the sorting machine body is movably installed with meshing gears, and there are two meshing gears, and the outer walls of the meshing gears are movably connected to the sprocket.

[0006] In order to facilitate locking of the screening frame, locking blocks are movably installed on the outer walls of both sides of the five screening frames. The locking blocks are located between two adjacent sliders, and there are ten locking blocks in total. Screens are fixedly installed on the inner walls of the five screening frames. Feed ports are movably connected to the left sides of the five screening frames, and there are five feed ports in total. Unscreened discharge ports are provided on the right sides of the five screening frames, and screening discharge ports are provided at the bottoms of the five screening frames.

[0007] In order to facilitate the automatic return of the push rod, the push rod is symmetrically connected with five movable blocks, and there are ten movable blocks in total. The tops of the two push rods are fixedly connected to limit springs, and the tops of the two limit springs are fixedly connected to the top inner wall of the sorting machine body.

[0008] In order to facilitate the automatic resetting of the positioning block, the front inner wall of the sorting machine body is symmetrically installed with movable shafts, and there are ten movable shafts. The outer walls of the movable shafts are fixedly installed with positioning blocks. The bottom of the positioning blocks is fixedly connected with torsion springs, and there are ten torsion springs. The bottom of the torsion spring is fixedly connected to the front inner wall of the sorting machine body.

[0009] In order to facilitate the stable sliding limit of the movable locking block and to be able to restrict the locking block, the ends of the locking blocks close to each other are provided with limit grooves, the outer walls of the locking blocks are fixedly installed with limit blocks, and the limit blocks are slidably connected to the limit grooves.

[0010] In order to achieve the restriction of the screening frame, fixing rods are symmetrically fixedly installed on both sides of the screening frame, and there are ten fixing rods. Positioning plates are fixedly installed on the ends of the fixing rods away from each other, and there are ten positioning plates. The outer walls of the fixing rods are sleeved with return springs, and there are ten return springs.

[0011] Compared with the prior art, the present invention has the following beneficial effects: by rotating the adjusting gear, while the adjusting gear rotates, the two racks meshing with the adjusting gear move in opposite directions driven by the adjusting gear, and the two racks pull the two sprockets respectively. The two sprockets are displaced under the pulling force of the racks, and at the same time drive the two meshing gears meshing with the two sprockets. The two meshing gears rotate under the pulling force of the two sprockets. At this time, the two push rods move downward under the pulling force of the two sprockets and pull the limit spring at the same time. The ten movable blocks slide in the direction of the movement of the push rods under the pulling force of the two push rods. When the locking block moves in the direction of the limit slot under the pulling of the movable block, the reset spring is compressed, and the positioning block rotates under the downward pressure of the locking block. At this time, the adjusting gear continues to be rotated to the appropriate position, and the positioning block disengages from the slot, thereby achieving the effect of simultaneously unlocking the five screening frames.

[0012] At this time, replace the appropriate screening frame as needed. After the replacement is completed, rotate the adjusting gear. The two racks meshing with the adjusting gear are reset under the rotation of the adjusting gear. At this time, the two positioning rods lose the tension of the sprocket, and the limit spring loses the tension and contracts, driving the movable block and the positioning rod to rise. As the movable block rises, the reset spring loses the tension and rebounds, driving the locking block to move in the direction of the limit slot. The positioning block loses the pressure of the locking block and is reset and engaged with the slot under the action of the torsion spring, achieving the effect of replacing the screening frame and locking the five screening frames at the same time.

[0013] The present invention drives a push rod and a locking block to unlock a plurality of screening frames at the same time by rotating an adjusting gear, and locks a plurality of screening frames at the same time by resetting the adjusting gear, thereby achieving an effect of easy replacement of the screen.

[0027] Example 2

[0028] In order to facilitate locking the screening frame 6, locking blocks 27 are movably installed on the outer walls of both sides of the five screening frames 6, the locking blocks 27 are located between two adjacent sliders 13, and there are ten locking blocks 27, the inner walls of the five screening frames 6 are fixedly installed with screens 23, the left sides of the five screening frames 6 are movably connected with feeding ports 2, and there are five feeding ports 2, the right sides of the five screening frames 6 are provided with unscreened discharge ports 24, and the bottoms of the five screening frames 6 are provided with screening discharge ports 3; in order to facilitate the automatic return of the push rod 11, five movable blocks 12 are symmetrically and movably connected inside the push rod 11, and there are ten movable blocks 12, the tops of the two push rods 11 are fixedly connected to limit springs 28, and the tops of the two limit springs 28 are fixedly connected to the top inner wall of the sorting machine body 1; in order to facilitate the automatic resetting of the positioning block 21, the inner wall of the front side of the sorting machine body 1 is symmetrically and movably installed with movable shafts 20, and there are ten movable shafts 20, the outer walls of the movable shafts 20 are fixedly installed with positioning blocks 21, and the bottoms of the positioning blocks 21 are fixedly connected with Torsion spring 18, and there are ten torsion springs 18, the bottom of the torsion spring 18 is fixedly connected to the front inner wall of the sorting machine body 1; in order to facilitate the movable locking block 27 to perform stable sliding limit and to be able to limit the locking block 27, the ends of the locking blocks 27 that are close to each other are provided with limit grooves 17, and the outer walls of the locking blocks 27 are fixedly installed with limit blocks 16, and the limit blocks 16 are slidably connected to the limit grooves 17; in order to achieve the restriction of the screening frame 6, the two sides of the screening frame 6 are symmetrically fixed with fixing rods 25, and there are ten fixing rods 25, and the ends of the fixing rods 25 that are away from each other are fixedly installed with positioning plates 15, and there are ten positioning plates 15, and the outer walls of the fixing rods 25 are sleeved with return springs 26, and there are ten return springs 26.

[0029] like Figure 1-8The working principle is as follows: by rotating the adjusting gear 7, while the adjusting gear 7 rotates, the two racks 8 meshing with the adjusting gear 7 move in opposite directions driven by the adjusting gear 7, and the two racks 8 pull the two sprockets 10 respectively. The two sprockets 10 are displaced under the pulling force of the racks 8, and at the same time drive the two meshing gears 9 meshing with the two sprockets 10. The two meshing gears 9 are rotated by the pulling force of the two sprockets 10. At this time, the two push rods 11 are pulled downward by the pulling force of the two sprockets 10 and pull the limit spring 28 at the same time. The ten movable blocks 12 slide in the direction of the movement of the push rods 11 under the pulling force of the two push rods 11. When the locking block 27 moves in the direction of the limit slot 17 under the pulling of the movable block 12, the reset spring 26 is compressed, and the positioning block 21 is rotated by the downward pressure of the locking block 27. At this time, it continues to rotate. The movable adjustment gear 7 is moved to a suitable position, and the positioning block 21 is disengaged from the slot 19, so that the five screening frames 6 are unlocked at the same time. At this time, the suitable screening frame 6 is replaced as needed. After the replacement is completed, the adjusting gear 7 is rotated, and the two racks 8 meshing with the adjusting gear 7 are reset under the rotation of the adjusting gear 7. At this time, the two positioning rods 11 lose the tension of the sprocket 10, and the limit spring 28 loses the tension and contracts, while driving the movable block 12 and the positioning rod 11 to rise. As the movable block 12 rises, the reset spring 26 loses the tension and rebounds, driving the locking block 27 to move in the direction of the limit slot 17. The positioning block 21 loses the pressure of the locking block 27 and is reset and engaged with the slot 19 under the action of the torsion spring 18, so that the five screening frames 6 are locked at the same time.

[0030] It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial changes or modifications are made to the present invention, the essence of the technical solution adopted is still the same as the present invention, so it should also be within the protection scope of the present invention.
