Description

Technical Field

[0001] This utility model relates to the field of superconducting magnetic separator technology, and more specifically, it relates to a protective housing for a superconducting magnetic separator. Background Technology

[0002] Superconducting magnetic separators utilize superconducting technology to generate a strong magnetic field, which is then used to separate materials through magnetic separation. A superconducting magnetic separator mainly consists of superconducting magnets, magnetic separation components, and a cold head. The superconducting magnets are composed of superconducting coils, which generate a high-intensity magnetic field when an electric current is applied. The primary function of the superconducting magnets is to generate a high-gradient magnetic field, causing the target substances within the material to be separated to experience a force within the magnetic field, thus leading to their separation.

[0003] Current superconducting magnetic separators, such as Figure 1 As shown, the superconducting magnet (not shown) is manufactured within a single, integral housing 1. This individual housing is generally quite thin, resulting in poor magnetic field isolation. Furthermore, the cold head 2 is located outside the housing 1 and contains various pipes, gas pipes, and wiring. These exposed pipes and wiring are highly susceptible to damage, which will cause downtime, affecting the magnetic separation efficiency and lifespan of the superconducting magnetic separator. In other words, current superconducting magnetic separators have poor magnetic field isolation and their piping and wiring are easily damaged, requiring improvement. Utility Model Content

[0004] To address this problem in practical applications, the present invention aims to provide a protective housing for a superconducting magnetic separator, the specific solution of which is as follows:

[0005] A protective housing for a superconducting magnetic separator includes an intermediate housing and end housings located at both ends of the intermediate housing. The end housings are detachably fixed to the intermediate housing. The intermediate housing has an internal channel along its axial direction, and the end housings have openings. The internal channel is connected to the openings.

[0006] Furthermore, the intermediate shell has an inverted U-shaped cross-section, so that the internal channel is not closed at the bottom.

[0007] Furthermore, the opening is located at the bottom center of the end housing.

[0008] Furthermore, the opening is composed of a connected upper opening and a lower opening, wherein the upper opening has a semi-circular structure, the lower opening has a rectangular structure, and the lower opening has an open bottom.

[0009] Furthermore, the protective housing is also provided with a wire conduit guide and fixing component, which is arranged along the axial direction of the intermediate housing.

[0010] Furthermore, the intermediate housing and the end housing are fixedly connected by bolts.

[0011] Furthermore, a heat dissipation window is provided on the end housing.

[0012] Furthermore, the protective housing is made of stainless steel.

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

[0014] In this invention, by setting a separate protective shell outside the original overall shell of the superconducting magnet, not only can a secondary isolation effect be achieved on the magnetic field, but the cold head and the wires and pipes involved in the machine are also isolated within the protective shell, which can protect them, prevent them from being damaged and affecting the operation of the machine, ensure working efficiency, and help improve the service life of the wires, pipes and the machine as a whole.

[0023] 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.

[0024] like Figure 1 As shown, Figure 1 The diagram shows an overall schematic of an existing superconducting magnetic separator, including an integral housing 1, a superconducting magnet, a separation tank, and a cold head 2. The superconducting magnet (not shown in the figure) is positioned at the center along the axial direction of the integral housing 1. A separation tank (not shown in the figure) is located inside the superconducting magnet along its axial direction, penetrating the superconducting magnet. The integral housing 1 covers the superconducting magnet and the separation tank. The cold head 2 is located on the upper part of the superconducting magnet and outside the integral housing 1. In addition, some pipes and lines (not shown in the figure) are also located outside the integral housing 1. Figure 1 In the middle, the area where the superconducting magnet is located is the protruding area of ​​the overall shell 1.

[0025] Given the shortcomings of current superconducting magnets, which only have an integral shell 1 as a protective layer and whose cold head 2, pipes, and lines are all located outside the integral shell 1 and are not protected, making them vulnerable to damage, this application provides a protective shell for superconducting magnetic separators. This shell not only provides secondary protection for the superconducting magnet part of the superconducting magnetic separator, but also protects the cold head 2, pipes, lines, etc., thereby improving the overall protection of the superconducting magnetic separator.

[0026] like Figure 2-3 As shown, a protective shell for a superconducting magnetic separator is provided to cover the superconducting magnet and the cold head of the superconducting magnetic separator. The separation tank penetrates the protective shell (not shown in the figure) so that the protective shell can protect and isolate the superconducting magnet and the cold head.

[0027] Specifically, such as Figure 4-7 As shown, the protective housing for the superconducting magnetic separator includes an intermediate housing 3 and end housings 4 located at both ends of the intermediate housing 3. The end housings 4 are detachably fixed to the intermediate housing 3. The intermediate housing 3 has an internal channel 5 along its axial direction, and the end housings 4 have openings 6, which are connected to the internal channel 5. The superconducting magnet and the cold head 2 are both located within the internal channel 5. The end housings 4 are used to seal both ends of the intermediate housing 3, and their openings 616 allow the separation tank to pass through. In this way, the arrangement of the separation tank can be maintained without affecting the secondary protection of the superconducting magnet and the cold head 2.

[0028] Among them, see Figure 4 The opening 6 is located at the bottom center of the end shell 4. The opening 6 is composed of a connected upper opening 61 and a lower opening 62, wherein the upper opening 61 has a semi-circular structure and the lower opening 62 has a rectangular structure, and the lower opening 62 has an open bottom. The shape of the opening 6 is designed to fit the shape of the separation tank and the overall shell 1.

[0029] See Figure 5 The cross-section of the middle shell 3 is in the shape of an inverted U-shape, so that the internal channel 5 is not closed at the bottom. The unclosed part at the bottom of the middle shell 3 cooperates with the overall shell itself to form a closed cover structure.

[0030] The intermediate housing 3 and the end housing 4 are fixedly connected by bolts, which facilitates disassembly and maintenance.

[0031] Figure 6 The diagram shows the state when the middle shell 3 is separated from the end shells 4 at both ends. Figure 7 The diagram shows the state when the middle shell 3 is connected to the end shells 4 at both ends.

[0032] In addition, a conduit guide and fixing component (not shown in the figure) is provided inside the protective housing, which is arranged along the axial direction of the intermediate housing 3. The conduit guide and fixing component can be a guide block provided along the inner wall of the intermediate housing 3, with a guide groove on the guide block. The size of the guide groove is adapted to the line or conduit, and the conduit is guided and fixed along the guide groove. Preferably, the guide block is arranged along the axial direction of the protective housing and can be a single guide block or a segmented multi-block guide block. The provision of the guide and fixing component ensures that the conduit is guided and fixed along the guide groove, improving the stability and safety of the conduit.

[0033] A heat dissipation window 7 is provided on the end housing 4, see Figure 4 The addition of heat dissipation window 7 enhances the heat dissipation performance of the protective shell, thus avoiding poor heat dissipation caused by adding a protective shell and helping to extend the service life of the superconducting magnetic separator.

[0034] The protective housing is made of stainless steel, which has good corrosion resistance and mechanical strength, ensuring the long-term performance of the protective housing.

[0035] 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.
