Description

Technical Field

[0001] This utility model relates to the field of iron separator technology, specifically to a permanent magnet multi-stage iron separator. Background Technology

[0002] Iron separators are used in fluids and semi-fluids of varying viscosities to remove iron impurities and other ferromagnetic particles, keeping the material clean while also protecting downstream production equipment.

[0003] To ensure the effective removal of iron impurities and other ferromagnetic particles, iron separators are often equipped with multiple magnetic rods. This causes the magnetic fields they generate to interfere with each other, which may deform the magnetic rods, affecting the filtration effect and the removal of the magnetic rods. At the same time, the impact force when the fluid material enters the iron separator may also cause the magnetic rods to deform. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a permanent magnet multi-stage iron separator.

[0005] The objective of this utility model can be achieved through the following technical solution: A permanent magnet multi-stage iron separator includes a frame, on which multiple filter cylinders are provided. Each filter cylinder is connected to a sealing cover by a locking buckle. Each filter cylinder is connected to the other via a material pipe. A baffle is provided inside the filter cylinder. A first fixing plate is provided above the baffle. A guide pipe is provided between the baffle and the first fixing plate. A magnetic rod is movably provided inside the guide pipe. Guide sleeves that abut against the magnetic rod are provided at both ends of the guide pipe. The top end of the magnetic rod is connected to the sealing cover.

[0006] Preferably, the frame is equipped with a cover opening assembly.

[0007] Preferably, the cover opening assembly includes a second fixing plate fixedly connected to the sealing cover, and the two ends of the second fixing plate are provided with guide rods slidably connected to the frame. The frame is provided with cylinders for driving the fixing plate to move up and down.

[0008] Preferably, the end of the magnetic rod has a tapered section, which is a non-magnetic region.

[0009] Preferably, a sealing ring is provided between the sealing cap and the filter cartridge.

[0010] Preferably, the bottom of the filter cartridge is connected to a drain pipe, and the drain pipe is equipped with a drain valve.

[0011] Preferably, the guide sleeve includes an annular mounting ring, with support blocks spaced apart on the mounting ring, and a tapered guide surface on the inner side of the support blocks.

[0012] Preferably, a guide groove is provided between two adjacent support blocks.

[0013] Preferably, the guide sleeve is made of a flexible material.

[0014] Preferably, the sealing cap is provided with a retaining sleeve for mounting the magnetic rod.

[0015] The beneficial effects of this utility model are: by setting guide sleeves at both ends of the guide tube, the magnetic rod is always kept in the middle of the guide tube, so that the material can pass through the gap between the guide tube and the magnetic rod evenly, which is conducive to improving the filtration effect. At the same time, it can also prevent the magnetic rod from being deformed due to the influence of the magnetic field generated by itself. Attached Figure Description

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figures 1 to 6 As shown, the structure of this utility model is as follows: it includes a frame 1, on which multiple filter cylinders 2 are provided to improve the filtration effect. Each filter cylinder 2 is connected to a sealing cover 4 via a latch 3 for easy removal. Each filter cylinder 2 is connected by a feed pipe 5. Material enters from one end of the feed pipe 5, passes through each filter cylinder 2 sequentially, and then exits from the other end of the feed pipe 5. A baffle 201 is provided inside each filter cylinder 2, blocking the material as it enters. A first fixing plate 202 is provided above the baffle 201. A guide pipe 6 is spaced between the baffle 201 and the first fixing plate 202. Material entering the filter cylinder 2 then passes through the guide pipe 6 in a concentrated manner. A magnetic rod 7 is movably installed inside the flow tube 6. The flow tube 6 concentrates the material and brings it close to the magnetic rod 7, allowing the magnetic rod 7 to better adsorb magnetic substances in the material and improve the filtration effect. The two ends of the flow tube 6 are provided with guide sleeves 601 that abut against the magnetic rod 7. The guide sleeves 601 support the magnetic rod 7 and keep it in the middle of the flow tube 6. This allows the material to pass evenly through the gap between the flow tube 6 and the magnetic rod 7, which is beneficial to improving the filtration effect. At the same time, it can also prevent the magnetic rod 7 from being deformed by the magnetic field it generates. The top of the magnetic rod 7 is connected to the sealing cover 4. When too much magnetic substance is adsorbed on the magnetic rod 7, the lock 3 can be loosened and the sealing cover 4 can be opened to remove all the magnetic rods 7 for cleaning.

[0028] Furthermore, the frame 1 is equipped with a cover opening assembly 8 for automatically lifting the sealing cover 4, which facilitates cleaning of the magnetic rod 7 and the inside of the filter cartridge 2.

[0029] Specifically, the opening assembly 8 includes a second fixing plate 801 fixedly connected to the sealing cover 4. The second fixing plate 801 is T-shaped to increase bending strength. Guide rods 802 that are slidably connected to the frame 1 are provided at both ends of the second fixing plate 801 to ensure the positional accuracy of the sealing cover 4 and the filter cartridge 2 and prevent deviation or misalignment. The frame 1 is provided with a cylinder 803 for driving the second fixing plate 801 to move up and down. The cylinder 803 is a self-locking cylinder that can be locked at any position, thus reducing the need for other auxiliary locking devices, thereby simplifying the structure of the entire system and improving work efficiency. Specifically, when opening the cover, the latch 3 used to lock the sealing cover 4 is released, and then the cylinder 803 drives the second fixing plate 801 to move upward, causing the sealing cover 4 to lift the magnetic rod 7. When closing the cover, the cylinder 803 drives the second fixing plate 801 to move downward, causing the sealing cover 4 to insert the magnetic rod 7 into the guide tube 6, and then the latch 3 is locked.

[0030] like Figure 5 As shown, the end of the magnetic rod 7 is provided with a tapered section 701, which is a non-magnetic area. When cleaning the magnetic rod 7, it is beneficial for the magnetic material on the magnetic rod 7 to fall off.

[0031] like Figure 6 As shown, a sealing ring 9 is provided between the sealing cover 4 and the filter cylinder 2 to ensure the sealing between the sealing cover 4 and the filter cylinder 2 and to prevent material from seeping out between the sealing cover 4 and the filter cylinder 2 during filtration.

[0032] like Figure 2 As shown, the bottom of the filter cylinder 2 is connected to a drain pipe 10, and a drain valve 11 is provided on the drain pipe 10. When cleaning the inside of the filter cylinder 2, the drain valve 11 is opened and the sewage is discharged from the drain pipe 10. When the filter cylinder 2 is working, the drain valve 11 is closed to prevent the material from flowing out of the drain pipe 10.

[0033] like Figure 4 As shown, the guide sleeve 601 includes an annular mounting ring 603, with support blocks 604 spaced apart on the mounting ring 603. The guide sleeve 601 is divided into an upper guide sleeve and a lower guide sleeve. The support blocks 604 of the upper guide sleeve are located on the lower side of the mounting ring 603, and the support blocks 604 of the lower guide sleeve are located on the upper side of the mounting ring 603. The inner side of the support blocks 604 is provided with a tapered guide surface 605, which plays a guiding role when the magnetic rod 7 is inserted.

[0034] Furthermore, a guide groove 602 is provided between two adjacent support blocks 604 to facilitate the entry of materials into the guide pipe 6.

[0035] Specifically, the guide sleeve 601 is made of flexible material to avoid scratching the magnetic rod 7. At the same time, it can also provide cushioning for the magnetic rod 7 when the material enters, so as to prevent the magnetic rod 7 from being damaged by the impact force when the material enters.

[0036] like Figure 3As shown, the sealing cover 4 is provided with a fixing sleeve 401 for installing the magnetic rod 7, which facilitates the installation and fixing of the magnetic rod 7 and prevents fingers from being pinched when disassembling and replacing the magnetic rod 7.

[0037] In practical use, the material enters the filter cylinder 2 from one end of the feed pipe 5, then passes through each filter cylinder 2 in sequence, and is discharged from the other end of the feed pipe 5. After entering the filter cylinder 2, the material is first blocked by the baffle 201, and then enters the guide pipe 6. The guide pipe 6 concentrates the material and brings it close to the magnetic rod 7, so that the magnetic rod 7 can better adsorb the magnetic substances in the material and improve the filtration effect. The guide sleeves 601 are set at both ends of the guide pipe 6 to support the magnetic rod 7, so that the magnetic rod 7 is always kept in the middle of the guide pipe 6, and the material can pass through the gap between the guide pipe 6 and the magnetic rod 7 evenly, which is beneficial to improving the filtration effect and at the same time can prevent the magnetic rod 7 from being deformed by the magnetic field generated by itself.

[0038] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
