Description

Technical Field

[0001] The utility model relates to the technical field of superconducting magnetic separators, and more specifically, it relates to an anti-leakage filter element. Background Art

[0002] A superconducting magnetic separator is a high magnetic field magnetic separator with a magnetic system coil wound by a superconductor. The materials captured by the superconducting magnetic separator are sorted by adsorption or changing the movement direction. The sorting space is a container, and steel wool medium is placed inside it to form a magnetic field gradient for sorting.

[0003] For the existing filter element for placing steel wool medium, its material is a metal material such as stainless steel. Since the hardness and strength of the stainless steel filter element are sufficient, there is no need to consider the sealing problem. However, the filter element made of stainless steel has a large interference of the metal material on the magnetic field in the magnetic field. The filter element made of a non-metallic material such as a plastic material can reduce the interference of the metal material on the magnetic field, but the plastic material is relatively soft and prone to slurry leakage. Based on this, the existing magnetic separator filter element needs to be improved. Summary of the Utility Model

[0004] Aiming at this problem in practical applications, the purpose of the present utility model is to propose an anti-leakage filter element, which can reduce the interference of metal materials on the magnetic field and can also achieve anti-leakage. The specific scheme is as follows:

[0005] An anti-leakage filter element includes a steel wool shell and at least one shunt disc located on the steel wool shell. Both the steel wool shell and the shunt disc are made of plastic material, and a sealing ring is provided at the connection between the steel wool shell and the shunt disc.

[0006] Further, the inner side wall of the steel wool shell has a protrusion along its circumferential direction;

[0007] The sealing ring is fixed to the outer circumference of the shunt disc;

[0008] The inner diameter of the protrusion is adapted to the outer diameter of the sealing ring.

[0009] Further, the maximum outer diameter of the shunt disc is the same as the outer diameter of the steel wool shell.

[0010] Further, the materials of both the steel wool shell and the shunt disc are polyoxymethylene.

[0011] Further, the sealing ring adopts an O-shaped silica gel ring.

[0012] Further, the protrusion and the steel wool shell are of an integral structure.

[0013] Further, the protrusion and the steel wool shell are of a split structure.

[0014] Further, the sealing ring is bonded to the outer side wall of the flow dividing disc.

[0015] Further, a groove adapted to the sealing ring is provided on the outer side wall of the flow dividing disc, and the sealing ring is fitted into the flow dividing disc through the groove.

[0016] Further, the sealing ring is pressed against the outer side wall of the flow dividing disc.

[0017] Further, a circle of first mounting holes is provided at the steel wool shell feed inlet, and a circle of second mounting holes is provided at one end of the flow dividing disc close to the sealing ring. The positions of the first mounting holes and the second mounting holes are adapted to the second mounting holes.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] By using POM materials for both the steel wool shell for placing steel wool media and the flow dividing disc to reduce the interference of metal materials on the magnetic field, and at the same time setting a sealing ring between the steel wool shell and the flow dividing disc to overcome the problem of slurry leakage caused by the relatively soft POM material itself, the whole filter element realizes anti-leakage while reducing the interference of metal materials on the magnetic field.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1

[0026] As Figure 1As shown in the figure, a leak-proof filter element includes a steel wool shell 1 and at least one shunt disc 2 located on the steel wool shell 1. Preferably, there are two shunt discs 2 during use. The two shunt discs 2 are stacked and fixed in the middle of two similarly stacked steel wool shells 1 (not shown in the figure) to form a filter element.

[0027] Figure 1 The figure shows a schematic structural diagram of a steel wool shell 1 and a shunt disc 2 when they are not connected. Among them, the steel wool shell 1 is in a sectional view state, and the shunt disc 2 is in a side view state.

[0028] In this embodiment, in combination with Figure 2 As shown in the figure, both the steel wool shell 1 and the shunt disc 2 are made of plastic materials, and a sealing ring 3 is provided at the connection between the steel wool shell 1 and the shunt disc 2. Preferably, the materials of both the steel wool shell 1 and the shunt disc 2 are polyoxymethylene (POM); the sealing ring 3 is an O-shaped silica gel ring.

[0029] Setting the materials of both the steel wool shell 1 and the shunt disc 2 to POM materials can reduce the interference of metal materials in the magnetic field on the magnetic field. Setting an O-shaped silica gel ring between the steel wool shell 1 and the shunt disc 2 can overcome the problem of slurry leakage caused by the relatively soft POM material.

[0030] More specifically, in combination with Figure 3 As shown in the figure, the steel wool shell 1 is a cylindrical container with a channel opened in the middle. One end is the feed end and the other end is the discharge end. (Not shown in the figure) The inner side wall of one end of the steel wool shell 1 near the feed port has a protrusion 4 along its circumference.

[0031] The shunt disc 2 is composed of a middle disc and cylindrical bodies connected to both sides of the middle disc. The middle disc and the cylindrical bodies form an integral structure. A channel is also opened in the middle of the middle disc (not shown in the figure). The sealing ring 3 is fixed on the outer circumference of one of the cylindrical bodies on the shunt disc 2; the inner diameter of the protrusion 4 is adapted to the outer diameter of the sealing ring 3. Preferably, the outer diameter of the sealing ring 3 is slightly larger than the inner diameter of the protrusion 4, so that when the sealing ring 3 is hermetically connected to the protrusion 4, the sealing ring 3 is squeezed to improve the sealing performance.

[0032] The outer diameter of the middle disc on the shunt disc 2 is the largest, and the outer diameter of this middle disc is the same as that of the steel wool shell 1, so that the outer diameter of the filter element formed after the shunt disc 2 is connected to the steel wool shell 1 is the same, in order to adapt to the installation of the superconducting magnetic separator.

[0033] In addition, the protrusion 4 and the steel wool shell 1 are of a split structure. The protrusion 4 is a ring made of POM material as well, and the ring can be fixed on the inner side wall of the steel wool shell 1 by means of bonding, screw fixing, etc. The split structure can facilitate the replacement of the protrusion 4, and there is no need to replace the entire steel wool shell 1 when the seal is damaged, saving the maintenance cost.

[0034] The sealing ring 3 is pressed against the outer side wall of the flow splitting disc 2. By utilizing the elastic effect of the silica gel ring itself, the sealing ring 3 is clamped tightly on the flow splitting disc 2, and the installation is simple.

[0035] Furthermore, the fixed connection mode between the steel wool shell 1 and the flow splitting disc 2 is as follows: a circle of first mounting holes 5 is provided at the feed inlet of the steel wool shell 1, and a circle of second mounting holes 6 is provided at one end of the flow splitting disc 2 close to the sealing ring 3. A plurality of first mounting holes 5 and second mounting holes 6 are circumferentially arranged, and the positions of the first mounting holes 5 and the second mounting holes 6 are adapted to the second mounting holes 6. In addition, bolts adapted to the two mounting holes are also provided, and the two mounting holes are fixed by the bolts to fix the steel wool shell 1 and the flow splitting disc 2.

[0036] During installation, steel wool is first pressed into the steel wool shell 1, and then one end of the flow splitting disc 2 enters the steel wool shell 1 until the sealing ring 3 thereon abuts against the protrusion 4 for sealing. Finally, the steel wool shell 1 and the flow splitting disc 2 are fixed by passing bolts through the first mounting holes 5 and the second mounting holes 6 and locking them with nuts, and the installation of the steel wool shell 1 and the flow splitting disc 2 can be completed.

[0037] Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that the protrusion 4 and the steel wool shell 1 are of an integral structure. During manufacturing, the protrusion 4 and the steel wool shell 1 are integrally injection-molded. The integral forming structure is convenient for assembly and use.

[0039] Embodiment 3

[0040] The difference between this embodiment and Embodiment 1 is that the sealing ring 3 is bonded to the outer side wall of the flow splitting disc 2. The bonding method can further improve the fastening property of the sealing ring 3 after installation, thereby ensuring the sealing property during use and avoiding the situation of the sealing ring 3 coming off the ring.

[0041] Embodiment 4

[0042] The difference between this embodiment and Embodiment 1 is that a circle of grooves adapted to the sealing ring 3 is provided on the outer side wall of the flow splitting disc 2, and the sealing ring 3 is fitted into the flow splitting disc 2 through the grooves. Similarly, it is to further improve the fastening property of the sealing ring 3 after installation and avoid the situation of the sealing ring 3 coming off the ring due to the axial acting force generated by disassembly, assembly and water flow.

[0043] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
