The magnetic separation mechanism 3 is disposed close to the conveying pipe 2, and a preset gap is provided between the magnetic separation mechanism 3 and the conveying pipe 2, which can be determined according to the actual situation, which is not limited in any way in the present embodiment. The magnetic separation mechanism 3 is rotatably arranged on the supporting device 1, so that the magnetic separation mechanism 3 attracts the iron-based substances in the material by utilizing a background magnetic field generated by the magnetic separation mechanism 3 and drives the iron-based substances to rotate together when the magnetic separation mechanism rotates, so that the iron-based substances rotate to the first outlet 22 of the conveying pipeline 2, and the iron-based substances are further output from the first outlet 22.
It can be seen that, in this embodiment, the magnetic separation mechanism 3 drives the iron-based substances in the conveying pipeline 2 to rotate together through rotation of the magnetic separation mechanism until the iron-based substances rotate to the first outlet 22 for outputting, so that automatic separation and outputting are realized, labor intensity is reduced, separation efficiency is improved, operation is simple, separation is convenient, and meanwhile, the first outlet 22 and the second outlet 23 are respectively provided with a device capable of respectively storing separated materials and iron-based catalysts, so that subsequent utilization is convenient.
Referring to fig. 1 and 6, in the above embodiment, both ends of the conveying pipe 2 are closed ends, and a material inlet 21 is formed in a side wall of an end portion of the first end (upper end shown in fig. 6) of the conveying pipe 2 to receive a material containing an iron catalyst. The side wall of the conveying pipe 2 near the second end (lower end shown in fig. 6) is provided with a first outlet 22 and a second outlet 23, and the first outlet 22 and the second outlet 23 can be provided at a certain distance.
In particular, the conveying pipe 2 is provided with inlet pipes corresponding to the material inlet 21 and outlet pipes corresponding to the first outlet 22 and the second outlet 23.
The conveying pipeline 2 is in an arc shape, the arc shape of the conveying pipeline 2 can be a major arc or a minor arc, and the embodiment does not limit the arc shape. In the present embodiment, the arc shape of the conveying pipe 2 is a major arc, and the conveying pipe 2 is integrally welded. In particular, the material of the conveying pipe 2 may be stainless steel, so as to be able to withstand a certain pressure.
The main pipe section of the conveying pipeline 2 and the magnetic separation mechanism 3 are provided with a first preset distance, the pipe section of the conveying pipeline 2 close to the second end is provided with a second preset distance from the magnetic separation mechanism 3, the second preset distance is larger than the first preset distance, and then the pipe section of the conveying pipeline 2 close to the second end is involute-shaped and gradually far away from the magnetic separation mechanism 3.
The present embodiment is not limited to the shape of the magnetic separation mechanism 3, and preferably, the magnetic separation mechanism 3 may have a substantially cylindrical shape to match the arc shape of the conveying pipe 2.
No matter how long the length of the conveying pipeline 2 is, i.e. no matter whether the arc shape of the conveying pipeline 2 is a major arc or a minor arc, the central part of the conveying pipeline 2 and the end part of the second end of the conveying pipeline 2 are respectively arranged at two sides of the vertical central axis of the magnetic separation mechanism 3. Specifically, referring to fig. 6, the vertical central axis of the magnetic separation mechanism 3 is the vertical axis L in fig. 6, the end of the second end of the conveying pipe 2 is placed to the left of the vertical axis L, and the center portion of the conveying pipe 2 is placed to the right of the vertical axis L.

Because the distance between the pipe section of the conveying pipeline 2 close to the second end and the magnetic separation mechanism 3 is large, a structure form far away from the magnetic field is formed, the magnetic attraction force of the magnetic separation mechanism 3 is gradually reduced, the iron-based catalyst is convenient to separate from the magnetic field until the magnetic attraction force at the first outlet 22 is reached, the iron-based material can be output from the first outlet 22, separation of the material and the iron-based material is realized, and the separation efficiency and the separation quality are effectively improved.

Specifically, the magnetic block 351 may be made of a permanent magnet material, so as to ensure a sufficient magnetic field. In the concrete implementation, the permanent magnet material can be selected according to the magnetic property of the iron-based substance and the different production environments, and particularly, the ferrite magnet, the neodymium-iron-boron magnet and the Gao Wenshan-resistant cobalt magnet can be selected so as to meet the requirement of performance and reduce the production cost. In this embodiment, the magnetic block 351 may be made of a rare earth neodymium iron boron or samarium cobalt material by firing.

The magnetic permeability yoke plate 352 and the magnetic block 351 form a closed loop, so that the magnetic penetration depth of a magnetic field is enhanced, and even if materials are more, iron-based substances in the magnetic permeability yoke plate can be attracted.
Each magnetic structure 35 may further include: two magnetic conductive plates 353. Wherein, two magnetic conductive plates 353 are respectively arranged at two opposite sides of the magnetic block 351 in a one-to-one correspondence. Specifically, each of the magnetic permeability plates 353 may be a Q235 magnetic permeability plate to enhance magnetic field performance.
In the present embodiment, the magnetic blocks 351 in each magnetic structure 35 are three, including: two rectangular magnetic blocks and a wedge-shaped magnetic block. One magnetic permeable yoke plate 352 and two magnetic permeable plates 353. Since the cross section of the connecting body 33 is circular, the outer wall of the connecting body 33 is circular, so that a wedge-shaped magnetic block is sandwiched between two rectangular magnetic blocks in each magnetic structure 35 to adapt to the shape of the connecting body 33. The magnetic yoke plate 352 is disposed at the bottoms of the two rectangular magnetic blocks and the wedge-shaped magnetic block and connected with the outer wall of the connector 33, and a preset gap is formed between the tops of the two rectangular magnetic blocks and the inner wall of the cylinder 32. The two magnetic conductive plates 353 are respectively arranged on two side surfaces of the two cuboid-shaped magnetic blocks, which are arranged on the outer side, that is, the two cuboid-shaped magnetic blocks and the wedge-shaped magnetic blocks are clamped between the two magnetic conductive plates 353.
In a specific implementation, since the connection body 33 is in a ring shape, a certain distance is provided between the two magnetic blocks 351 in order to adapt to the shape of the connection body 33, as shown in fig. 4.
Referring to fig. 1, in each of the above embodiments, the separation device may further include: and a protective cover 4. Wherein the protective cover 4 is arranged on the support device 1 and the conveying pipe 2 and at least part of the magnetic separating mechanism 3 are arranged inside the protective cover 4. Specifically, the protection cover 4 and the supporting device 1 are detachably connected, such as a bolt connection, which is not limited in this embodiment. The conveying pipeline 2 and the cylinder 32 in the magnetic separation mechanism 3 are both arranged in the protective cover 4, two ends of the rotating shaft 34 penetrate through the protective cover 4 and are arranged outside the protective cover 4, the two bearing seats 5 are both arranged outside the protective cover 4, and the driving mechanism 31 is arranged outside the protective cover 4.
In practice, the inlet pipe at the material inlet 21 of the conveying pipe 2 extends out of the protective cover 4 and its end is placed outside the protective cover 4, and the outlet pipes at the two outlets of the conveying pipe 2 also extend out of the protective cover 4 and their ends are placed outside the protective cover 4.
It can be seen that in this embodiment, the setting of the protection cover 4 can effectively protect the cylinder 32 and the conveying pipeline 2, avoid the influence of external sundries to the magnetic field in the cylinder 32, also can avoid the attraction of the magnetic field in the cylinder 32 to external other substances, ensure the effective separation of the iron-based substances in the conveying pipeline 2, and ensure the cleaning of the separator, and also ensure that other personnel are not easy to contact with the rotating parts, and ensure the personal safety of the personnel.
The use of the separation device will be described with reference to fig. 1 to 6: the material containing iron-based substances enters the conveying pipeline 2 from the inlet of the conveying pipeline 2. The driving mechanism 31 drives the connecting body 33 to rotate through the rotating shaft 34, and drives the magnetic structures 35 on the connecting body 33 to rotate together, so that a stable background magnetic field is formed, and iron-based substances in the materials are attracted. The iron-based substance rotates together with the cylinder 32 under the attraction of the plurality of magnetic structures 35 and moves toward the second end of the delivery pipe 2. Since the gap between the pipe section of the transfer pipe 2 near the second end and the cylinder 32 is gradually increased, the attraction of the magnetic structure 35 to the iron-based substance is gradually decreased, and when the iron-based substance moves to the first outlet 22, the iron-based substance is not attracted any more as the attraction of the magnetic structure 35 is decreased, and the iron-based substance can be outputted from the first outlet 22. The material from which the iron-based material is separated is output from the second outlet 23 under the action of gravity, thereby realizing the separation of the material and the iron-based material.
To sum up, in this embodiment, attract the iron-based material in the conveying pipeline 2 through the magnetism separating mechanism 3 for the iron-based material separates from the material, has realized the separation of material and iron-based material, has reduced the content of iron-based catalyst in the material, has improved separation effect, need not to add other materials in this separation process, just can not produce danger useless material like in prior art yet, also need not to filter, can guarantee to separate in succession, uninterrupted cycle handles, has improved separation efficiency, has reduced intensity of labour, and, simple structure need not many sets of devices reserve, has reduced manufacturing cost.
