Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation equipment, in particular to a magnetic separator. Background Art

[0002] A magnetic separator is a screening device used to remove iron powder from recycled powdered particles. Traditional magnetic separators are drum-type magnetic mechanisms installed at the output end of a conveyor belt used to transport powdered particles. They use magnetic force to filter out iron powder from the powdered particles.

[0003] However, during the operation of traditional magnetic separation equipment, the conveyor belt acts on the powder particles, which gives the powder particles a certain inertia, making it easy for the magnetic separation equipment to fail to absorb some iron powder, resulting in incomplete screening. Utility Model Content

[0004] In view of the technical problem that existing magnetic separation equipment has incomplete screening of iron powder, the utility model provides a magnetic separator, which has the advantage of improving the screening ability of iron powder in powdery particles by increasing the magnetic attraction time in powdery particles.

[0005] The technical solution of the utility model is:

[0006] A magnetic separator, comprising:

[0007] A conveyor belt for conveying slag, wherein the conveyor belt has a section extending in an inclined upward direction;

[0008] At least three support members are respectively provided at three end points of a triangular structure, each support member has two sprockets, and the two sprockets on the same support member are coaxially distributed;

[0009] Two chains are mounted on three supports and are arranged parallel to each other;

[0010] A belt, both sides of which are respectively arranged on the two chains, and form a magnetic separation triangle structure;

[0011] A plurality of electromagnets are evenly distributed on the belt, and the electromagnets are located inside the magnetic separation triangle structure;

[0012] a motor, the output shaft of which is dynamically connected to a sprocket on one of the supports;

[0013] One side of the magnetic selection triangle structure is parallel to a section of the conveyor belt in an inclined structure, and the magnetic selection triangle structure has another side with a downwardly inclined movement direction relative to a horizontal plane.

[0014] Optionally, it also includes:

[0015] The conductive rod is located inside the magnetic selection triangle structure and is arranged along the three sides of the magnetic selection triangle structure to form a power supply triangle structure;

[0016] A plurality of brushes are correspondingly provided on the electromagnets and are in sliding contact with the power supply triangle structure;

[0017] There are two power supply triangle structures, which are respectively close to the two sides of the magnetic selection triangle structure, and each electromagnet is correspondingly equipped with two brushes, which are in sliding contact with the two power supply triangle structures respectively.

[0018] Optionally, the power supply triangle structure has a vacant structure, and the vacant structure is close to a position where the magnetic selection triangle structure moves obliquely downward.

[0019] Optionally, it also includes:

[0020] The lead-out trough is arranged below a section of the magnetic selection triangle structure that moves obliquely downward, and its lead-out direction is perpendicular to the moving direction of the conveyor belt.

[0021] Optionally, the support member includes:

[0022] Multiple support rods are arranged parallel to each other;

[0023] Among them, there are two support rods close to a section of the conveyor belt that moves in an inclined upward direction, and two connecting rods are respectively provided on the two support rods. One end of the connecting rod extends in a direction perpendicular to this section of the conveyor belt and is close to the conveyor belt, and the sprocket is provided on this end of the connecting rod.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] First, a conveyor belt is set, and a section of the conveyor belt is set in an inclined direction, and then the powder particles are transported by the conveyor belt, and the conveying direction is downward in the inclined upward section.

[0026] Then a magnetic separation triangle structure is set above the conveyor belt, the belt is driven by a motor to rotate, and the electromagnet on the belt is used to screen the powder particles in the conveyor belt.

[0027] In this technical solution, since one section of the magnetic separation triangle structure and the section of the conveyor belt that is inclined upward are designed to be parallel to each other, the magnetic attraction time of the entire magnetic separation triangle structure in the powder particles is increased, thereby improving the iron powder screening ability in the powder particles.

As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] See also Figure 1-Figure 3 This embodiment discloses a magnetic separator, comprising a conveyor belt 1, a support member 2, a sprocket 3, a chain 4, a belt 5, an electromagnet 6, and a motor (not shown). Specifically, the conveyor belt 1 comprises two sections, one of which is arranged horizontally and the other is arranged in an inclined upward direction.

[0037] There are at least three support members 2, which are distributed at the three end points of a triangular structure. Each support member 2 has two sprockets 3, and the two sprockets 3 on the same support member 2 are coaxially arranged. There are two support members 2 at the two ends of a section of the inclined structure close to the conveyor belt 1.

[0038] Two chains 4 are arranged on all the sprockets 3 to form two triangular structures composed of the chains 4 . The two triangular structures are respectively close to two sides of the conveyor belt 1 .

[0039] A belt 5 is installed on the triangular structure formed by two chains 4. Both sides of the belt 5 are connected to the two chains 4, forming a magnetic separation triangle structure composed of the belt 5. One side of the magnetic separation triangle structure is arranged parallel to the upward-slanting section of the conveyor belt 1 and is close to this section of the conveyor belt 1. In addition, the magnetic separation triangle structure has another side arranged in a downward-slanting direction relative to the horizontal plane.

[0040] A plurality of electromagnets 6 are provided on the belt 5, and all of the electromagnets 6 are provided on the inner side of the magnetic selection triangle structure. The sprocket 3 on the above-mentioned support member 2 is connected to the output shaft power of the motor, and the sprocket 3, chain 4 and belt 5 are driven by the motor.

[0041] In this embodiment, the conveyor belt 1 is first provided, and a section of the conveyor belt 1 is provided in an inclined direction. Then, the powdered particles are conveyed by the conveyor belt 1 , and the conveying direction is downward in the inclined upward section.

[0042] Then, a magnetic separation triangle structure is set above the conveyor belt 1, the belt 5 is driven to rotate by a motor, and the electromagnet 6 on the belt 5 is used to screen the powder particles in the conveyor belt 1.

[0043] In this technical solution, since one section of the magnetic separation triangle structure and the section of the conveyor belt 1 that is inclined upward are designed to be parallel to each other, the magnetic attraction time of the entire magnetic separation triangle structure in the powder particles is increased, thereby improving the iron powder screening ability in the powder particles.

[0044] In one specific embodiment:

[0045] The magnetic separator also includes a conductive rod 7 and brushes 8. The conductive rod 7 is positioned inside the magnetic separation triangle structure, and its extension direction aligns with the three sides of the magnetic separation triangle structure, forming a power supply triangle structure. The power supply triangle structure and the magnetic separation triangle structure are similar triangles. Gaps exist between the three sides of the power supply triangle structure and the three sides of the magnetic separation triangle structure.

[0046] The electromagnet 6 is provided with a brush 8, which is in sliding contact with the power supply triangle structure. In this embodiment, there are two power supply triangle structures, which are respectively provided near the two sides of the magnetic separation triangle structure.

[0047] The two motors on the same electromagnetic are respectively connected to two different brushes 8, and then the two brushes 8 are respectively in sliding contact with two conductive triangle structures.

[0048] In this embodiment, two conductive triangle structures are provided to simplify the power supply circuits of all electromagnets 6 .

[0049] Preferably, the power triangle has a gap near the magnetic separation triangle, which is tilted downward. This gap allows the iron powder attracted by the electromagnet 6 to fall off when it reaches this gap. The electromagnet 6 loses power and the magnetic force disappears, allowing the attracted iron powder to fall off, thereby removing the iron powder from the electromagnet 6.

[0050] In addition, a lead-out trough 9 can be provided below the magnetic separation triangle structure, and the lead-out trough 9 is located below the vacant structure on the power supply triangle structure, so that the magnetically attracted iron powder will automatically fall into the lead-out trough 9 for easy recovery of the iron powder.

[0051] In another specific embodiment:

[0052] The support member 2 includes support rods and connecting rods. There are multiple support rods, all of which are parallel to each other. At least two support rods are located near the ends of the conveyor belt 1, which is inclined upward. Two connecting rods are installed on each of these two support rods. The connecting rods are arranged perpendicular to the support rods, and the ends of the connecting rods away from the support rods extend toward the conveyor belt 1. The sprocket 3 is mounted on this end of the connecting rod.

[0053] In this embodiment, by providing a connecting rod, a section of the magnetic separation triangle structure can be extended into a section of the conveyor belt 1 in an inclined direction, so as to achieve the purpose of improving the magnetic separation effect.

[0054] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
