Description

Technical Field

[0001] This utility model relates to the field of superconducting magnetic separation technology, and more specifically, it relates to a demagnetizing device. Background Technology

[0002] In existing technologies, superconducting magnetic separators, as highly efficient mineral separation equipment, have core components including a superconducting magnet and a separation chamber. The superconducting magnet is responsible for generating a strong magnetic field, providing the necessary magnetic environment for the magnetic separation process. The separation chamber, as the key area for material separation, is filled with magnetically conductive stainless steel wool to enhance the magnetic field gradient and significantly improve separation efficiency.

[0003] However, in practical applications, because the separation chamber is designed as a moving device, it needs to leave the magnetic area after sorting. During this process, some mineral particles remain and adhere to the magnetically conductive stainless steel bristles inside the separation chamber. These residual mineral particles are often difficult to remove completely during subsequent rinsing, leading to prolonged rinsing time and increased cleaning frequency of the separation tank. More seriously, these adhered mineral particles can also adversely affect the quality of subsequent product processing, reducing overall production efficiency and product quality.

[0004] Therefore, in response to this problem in the existing technology, there is an urgent need for an improved solution that can effectively solve the problem of mineral particle adhesion, improve rinsing efficiency, and ensure product processing quality. Utility Model Content

[0005] To address this problem in practical applications, the purpose of this invention is to propose a demagnetizing device that solves the problem of mineral particle adhesion, improves rinsing efficiency, and ensures the quality of subsequent product processing. The specific solution is as follows:

[0006] A demagnetizing device is used to demagnetize mineral particles that remain and adhere to the magnetic stainless steel wool inside the separation tank of a superconducting magnetic separator. The device includes a magnet ring, an electromagnetic coil, and a control cabinet. The magnet ring is located at the outer end of the superconducting magnetic separator and is sleeved on the outside of the separation tank. The electromagnetic coil is located on the top of the magnet ring and is electrically connected to the control cabinet. When the electromagnetic coil is energized, it generates a reverse magnetic field through interaction with the magnet ring.

[0007] Furthermore, the magnet ring is a circular ring.

[0008] Furthermore, the central axis of the magnet ring and the central axis of the separation tank are on the same straight line.

[0009] Furthermore, the superconducting magnetic separator is equipped with the demagnetizing device at both ends of its exterior, and the two demagnetizing devices are symmetrically arranged about the superconducting magnetic separator.

[0010] Furthermore, the magnet ring is located 5-8 cm outside one end of the superconducting magnetic separator.

[0011] Furthermore, it also includes a support frame, the magnet ring is fixed on the support frame, and the control cabinet is installed at one end of the support frame.

[0012] Furthermore, the inner wall of the magnet ring is connected to several rolling elements that roll around it in the circumference, and one end of each rolling element rolls into contact with the outer wall of the separation tank.

[0013] Furthermore, the rolling element is tumblingly connected to the adjusting seat, and the inner sidewall of the magnet ring has a groove at a corresponding position on the adjusting seat, with the adjusting seat and the groove being interference fit.

[0014] Furthermore, it also includes an elastic adjusting member, which is located in the groove, with one end of the elastic adjusting member fixed to the adjusting seat and the other end fixed to the magnetic ring.

[0015] Furthermore, the rolling element, adjusting seat, and elastic adjusting element are all made of non-magnetic material.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) By setting a magnet ring, an electromagnetic coil and a control cabinet at the outer end of the superconducting magnet, the mineral particles adhering to the magnetic stainless steel wool can be demagnetized. This makes it easier to clean the separation chamber during subsequent rinsing, which helps to reduce rinsing time. Furthermore, due to the improved rinsing effect, the frequency of the separation tank needing to be removed for deep cleaning is also reduced. In addition, the more thorough rinsing results in better quality of subsequent product processing.

[0018] (2) By setting up rolling parts, adjusting seats and elastic adjusting parts, not only can the friction force during the movement of the separation tank be reduced, so as to facilitate the movement of the separation tank, but also the structure of separation tanks with different diameters can be adapted to improve the adaptability of the demagnetizing device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, a demagnetizing device includes a magnet ring 2, an electromagnetic coil 3, a control cabinet 4, and a support frame 5. The magnet ring 2 is fixed to the support frame 5, and the electromagnetic coil 3 is located on the top of the magnet ring 2. The electromagnetic coil 3 is electrically connected to the control cabinet 4, which is mounted on one end of the support frame 5. The control cabinet 4 controls the electromagnetic coil 3 to be energized or de-energized. When the electromagnetic coil 3 is energized, the control cabinet 4 controls the direction of the current in the electromagnetic coil 3 to be opposite to the direction of the magnetic field of the magnet ring 2. The magnetic field generated by the electromagnetic coil 3 interacts with the magnetic field of the magnet ring 2. According to the principle of electromagnetic induction, the direction of the current in the electromagnetic coil 3 is opposite to the direction of the magnetic field of the magnet ring 2, and the magnet ring 2 generates a reverse magnetic field.

[0028] like Figure 2-3 As shown, the demagnetizing device of this application is used to demagnetize mineral particles that remain and adhere to the magnetically conductive stainless steel wool inside the separation tank 1 on the superconducting magnetic separator. Based on this, the magnetic ring 2 is located at the outer end of the superconducting magnetic separator and is sleeved on the outside of the separation tank 1. The separation tank 1 has a separation chamber (not shown in the figure), which is filled with magnetically conductive stainless steel (not shown in the figure).

[0029] Separator 1 is a movable device. After the sorting space within the separation chamber leaves the superconducting magnet, it is moved to the position of magnet ring 2. When energized, magnet ring 2 generates a reverse magnetic field, which is opposite in direction to the magnetic field previously generated by the superconducting magnet. This effectively weakens the magnetic force on the magnetically conductive stainless steel bristles within the separation chamber, demagnetizing the mineral particles remaining and adhering to them. These mineral particles no longer adhere to the bristles, making subsequent rinsing of the separation chamber easier and reducing rinsing time. Furthermore, due to the improved rinsing effect, the frequency of removing separator 1 for deep cleaning is reduced, thus improving rinsing efficiency and reducing maintenance workload. In addition, the more thorough rinsing results in better quality subsequent product processing.

[0030] It should be noted that, since this application does not involve any improvement to the superconducting magnetic separator itself, its specific structure is not shown in the figures. Furthermore, the separating tank 1, as a moving device, is prior art, and this application does not involve any improvement to it; therefore, the moving structure and operating principle of the separating tank 1 will not be described in detail here.

[0031] In addition, to ensure the stability of the separator 1 during operation or when stationary, several brackets (not shown in the figure) can be installed on the support frame 5. The brackets are arranged along the axial direction of the separator 1 to support the separator 1.

[0032] In this application, since the separation tank 1 has a circular tank structure, the magnet ring 2 is preferably a circular ring in order to fit the separation tank 1. Furthermore, the central axis of the magnet ring 2 is on the same straight line as the central axis of the separation tank 1, so that the mineral particles adhering to the magnetic stainless steel wool around the separation chamber can be uniformly demagnetized.

[0033] Furthermore, both ends of the superconducting magnetic separator are equipped with demagnetizing devices, and the two demagnetizing devices are symmetrically arranged about the vertical center of the superconducting magnetic separator. Each magnetic ring 2 is located 5-8 cm away from one end of the superconducting magnetic separator. Preferably, it is 5 cm, which is also to match the distance of the separation tank 1 when it moves to the outside of the superconducting magnetic separator, so as to ensure that demagnetization can be carried out normally.

[0034] Control cabinet 4 can use a PLC controller; there are no restrictions on this.

[0035] Example 2

[0036] The technical features that distinguish this embodiment from Embodiment 1 are as follows: Figure 4-5 As shown, the magnet ring 2 in this embodiment also includes a structure for facilitating the movement of the separation tank 1 and adapting to separation tanks 1 of different diameters.

[0037] Specifically, a plurality of rolling elements 6 are rolled along the circumference of the inner wall of the magnetic ring 2, with one end of each rolling element 6 making rolling contact with the outer wall of the separation tank 1. Preferably, the rolling elements 6 are ball bearings, rollers, or similar structures. Using rolling elements 6 to connect the magnetic ring 2 and the separation tank 1 not only provides support for the separation tank 1, but also reduces friction during movement of the separation tank 1 through rolling contact, thus facilitating its movement.

[0038] Furthermore, the rolling element 6 is tumblingly connected to the adjusting seat 7, and the inner sidewall of the magnet ring 2 has a groove 8 at the corresponding position on the adjusting seat 7, with the adjusting seat 7 and the groove 8 being interference-fitted. By setting the adjusting seat 7, its position can be adjusted radially along the magnet ring 2, thereby adjusting the position of the rolling element 6 radially along the magnet ring 2. This not only accommodates separation tanks 1 of different diameters but also adapts to radial offsets that may occur during the movement of the separation tank 1, improving its adaptability.

[0039] Furthermore, to improve the stability of the adjusting seat 7 during the adjustment process, this application also includes an elastic adjusting member 9. The elastic adjusting member 9 is located within the groove 8, with one end fixed to the adjusting seat 7 and the other end fixed to the magnetic ring 2. By using the elastic adjusting member 9 to fix the adjusting seat 7 and the magnetic ring 2 together, not only is normal radial adjustment of the adjusting seat 7 ensured, but also the occurrence of the adjusting seat 7 coming off or jamming is prevented, thereby improving adjustment stability. Preferably, the elastic adjusting member 9 can be an elastic structure such as a spring.

[0040] Finally, the rolling element 6, the adjusting seat 7, and the elastic adjusting element 9 are all made of non-magnetic materials to avoid affecting the magnetic field environment of the magnet ring 2. The rolling element 6 and the adjusting seat 7 can be made of stainless steel, plastic, or other materials, and the elastic adjusting element 9 can be made of any one of steel wire compression spring, rubber spring, or composite spring.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
