Description

Technical Field

[0001] The utility model relates to the technical field of magnetic screening, in particular to a magnetic screening device. Background Art

[0002] At present, various impurities are often mixed in during the production and use of raw materials. These impurities will affect the performance and quality of the raw materials, especially iron impurities. If they enter the electrolytic copper foil production system, they will cause system pollution and product scrapping.

[0003] Iron impurities are generally removed by magnetic screening equipment for adsorption removal. However, in current magnetic screening equipment, after the magnetic rods adsorb the iron impurities, it is difficult for workers to clean the iron impurities adsorbed on the magnetic rods. Moreover, when workers clean the iron impurities, the iron impurities are easily dropped into the box, causing contamination to subsequent raw materials.

[0004] CN202123299340 discloses a water drop-shaped magnetic rod de-ironizing magnetic frame, including a box body, the top of the box body is movably connected to a box cover by a hinge, the top of the box cover is connected to a feed pipe, a snap-fit ​​structure is provided between the front side of the box body and the box cover, the right side of the box body is fixedly connected to a transmission assembly, the left side of the box body is fixedly connected to a bearing seat, the surface of the bearing seat is provided with a hollow tube, the right side of the hollow tube is fixedly connected to the box body, the inner cavity of the hollow tube is fixedly connected to a limit plate, the inner cavity of the bearing seat is movably connected to a rotating rod, the right side of the rotating rod extends to the inner cavity of the box body, the right side of the rotating rod is provided with four limit slots, the surface of the rotating rod is provided with a rotating plate, both sides of the rotating plate are fixedly connected to a magnetic rod body, and the shape of the magnetic rod body is water drop-shaped. The de-ironizing magnetic frame is made by disengaging the motor from the rotating rod, thereby taking the magnetic rod body out of the box for cleaning, but taking the rotating rod and the magnetic rod body out of the box together is heavy, and the operation is more complicated and the efficiency is lower.

[0005] The technical problem to be solved by the utility model is: how to improve the efficiency and effect of cleaning iron impurities on the magnetic rod. Utility Model Content

[0006] The main purpose of this utility model is to provide a magnetic screening device. By providing a detachable coating unit on a magnetic adsorption unit, iron impurities on the raw material are adsorbed on the coating unit by the magnetic force of the magnetic adsorption unit. When it is necessary to clean the iron impurities in the device, it is only necessary to open the box cover and remove the coating unit. The coating unit can then be wrapped around the iron impurities and separated from the device, completing the cleaning operation. In this way, the cleaning efficiency is improved, and the iron impurities are prevented from falling into the box, maintaining the cleaning effect.

[0007] To achieve the above objectives, the technical solutions adopted in this application are:

[0008] A magnetic screening device comprises a housing, a magnetic adsorption unit for adsorbing iron impurities, and a driving unit for driving the magnetic adsorption unit to rotate; the housing is provided with an opening for feeding; the magnetic adsorption unit is rotatably connected to the housing; the housing is provided with a discharge port; and further comprises a covering unit, the covering unit covering the magnetic adsorption unit and being detachably connected to the magnetic adsorption unit.

[0009] The magnetic adsorption unit adsorbs the iron impurities on the coating unit. When the coating unit is removed, the coating unit wraps the iron impurities and separates from the magnetic adsorption unit.

[0010] Compared with the existing technology, this solution has the following beneficial effects:

[0011] The magnetic screening device in this case is equipped with a detachable coating unit on the magnetic adsorption unit. When the iron impurities in the device need to be cleaned, the staff only need to disassemble the coating unit and take the iron impurities out of the device with the coating unit wrapped. This method replaces the use of scrapers to scrape and clean the magnetic rods or pull out the magnetic rods, preventing iron impurities from being scattered below the box and contaminating subsequent raw materials. This device only needs to disassemble the coating unit to complete the cleaning, reducing the labor intensity of the staff. Moreover, when cleaning iron impurities, the iron impurities will not fall into the box, improving the cleaning effect of iron impurities. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Example 1

[0020] refer to Figure 1-5 A magnetic screening device includes a box body 1, a magnetic adsorption unit 2 for adsorbing iron impurities, and a driving unit 3 for driving the magnetic adsorption unit 2 to rotate; the box body 1 is provided with an opening 12 for feeding; the magnetic adsorption unit 2 is rotatably connected to the box body 1; the box body 1 is provided with a discharge port 11; and further includes a covering unit 5, the covering unit 5 covering the magnetic adsorption unit 2 and being detachably connected to the magnetic adsorption unit 2;

[0021] The magnetic adsorption unit 2 adsorbs the iron impurities on the coating unit 5. When the coating unit 5 is removed, the coating unit 5 wraps the iron impurities and separates from the magnetic adsorption unit 2 together.

[0022] In this embodiment, the drive unit 3 is a motor. The magnetic screening device operates as follows: raw materials enter the interior of the housing 1 through the opening 12. The drive unit 3 drives the magnetic adsorption unit 2 to rotate. During the rotation, the magnetic adsorption unit 2 adsorbs iron impurities in the material. The iron impurities are then adsorbed on the coating unit 5. The raw materials are then discharged from the discharge port 11 to the next process.

[0023] After the magnetic screening device has been used for a period of time, the iron impurities on the magnetic adsorption unit 2 need to be cleaned. During cleaning, the staff only needs to disassemble the covering unit 5, and then put the covering unit 5 back together to wrap the iron impurities inside the covering unit 5, and then take the covering unit 5 and the iron impurities out of the box 1. In this way, the cleaning can be completed without removing the magnetic adsorption unit 2, and the iron impurities can be prevented from falling into the box 1, thereby affecting the quality of the next raw material, reducing the labor intensity of the staff.

[0024] Preferably, a box cover 4 for covering the opening 12 is provided on the top of the box body 1 ; the box cover 4 is rotatably connected to the box body 1 ; and the box cover 4 is provided with a feed port 41 .

[0025] In this embodiment, the box body 1 is provided with an openable and closable box cover 4. The raw materials enter from the feed port 41 and enter the box body 1 through the opening 12. The provision of the box cover 4 can prevent part of the raw materials from floating to the outside when entering the box body 1 and polluting the external environment.

[0026] Preferably, the magnetic adsorption unit 2 includes a rotating shaft 21 and multiple magnetic rods 22; the rotating shaft 21 is rotatably connected to the box 1; the power output end of the driving unit 3 is connected to the rotating shaft 21; the multiple magnetic rods 22 are arranged in a circular array on the rotating shaft 21.

[0027] In this embodiment, the magnetic rods 22 are rotatably connected to the rotating shaft 21 and arranged in a circular array on the rotating shaft 21. The drive unit 3 drives the rotating shaft 21 to rotate, thereby driving the magnetic rods 22 to rotate. After the raw material is delivered into the housing 1 through the feed port 41, the raw material comes into contact with the magnetic rods 22. The rotation of the magnetic rods 22 driven by the drive unit 3 and the resulting rotation of the magnetic rods 22 during contact with the raw material increase the contact area between the magnetic rods 22 and the raw material, thereby improving the effectiveness of the magnetic rods 22 in adsorbing iron impurities.

[0028] Preferably, a connecting frame 211 connected to the magnetic rod 22 is provided on the rotating shaft 21 ; the connecting frame 211 is in a Y-shape, a cross-shape, a 'P'-shape or a star-shape; and each end of the magnetic rod 22 is connected to the connecting frame 211 .

[0029] In this embodiment, the connecting frame 211 is preferably shaped like a cross, which increases the number of magnetic rods 22 and improves the efficiency of adsorbing iron impurities. The magnetic rods 22 are rotatably connected to each end of the connecting frame 211. When the drive unit 3 drives the magnetic rods 22 to rotate, the magnetic rods 22 rub against the raw material and rotate, increasing the contact area between the magnetic rods 22 and the raw material, thereby better adsorbing iron impurities.

[0030] Preferably, the covering unit 5 includes a covering module 51 and a fixing module 52; the two fixing modules 52 are respectively connected to the two ends of the covering module 51; the covering module 51 is covered on the magnetic adsorption unit 2 through the fixing module 52 and is detachably connected to the magnetic adsorption unit 2.

[0031] In this embodiment, the ends of the coating module 51 are connected by fixing modules 52, which are then connected to the ends of the magnetic rod 22, so that the coating module 51 can wrap the entire surface of the magnetic rod 22. When the magnetic rod 22 is in operation, iron impurities are attracted by the magnetic rod 22 and are thus adsorbed on the coating module 51.

[0032] Preferably, the fixing module 52 includes a first semicircular ring 521 and a second semicircular ring 522; one end of the first semicircular ring 521 is rotatably connected to one end of the second semicircular ring 522, and the other end of the first semicircular ring 521 is detachably connected to the other end of the second semicircular ring 522; the end of the covering module 51 is connected to the first semicircular ring 521 and the second semicircular ring 522.

[0033] In this embodiment, one end of the covering module 51 is connected to the first semicircular ring 521 and the second semicircular ring 522, and the other end of the covering module 51 is connected in the same manner. The staff first opens the first semicircular ring 521 and the second semicircular ring 522, puts the first semicircular ring 521 and the second semicircular ring 522 on the magnetic rod 22, and then merges the first semicircular ring 521 and the second semicircular ring 522 into a circular ring in a detachable manner, and fixes it on the magnetic rod 22, so that the covering module 51 wraps the magnetic rod 22. The detachable manner can be a snap connection, a bolt connection, etc.

[0034] More preferably, iron blocks are arranged at intervals at both ends of the coating module 51. After the coating module 51 wraps the magnetic rod 22, the iron blocks at both ends of the coating module 51 are affected by the magnetic force of the magnetic rod 22, so that the iron blocks press the edges of the coating module 51 against the magnetic rod 22, thereby preventing raw materials or iron impurities from entering the magnetic rod 22 from the gap when the two ends of the coating module 51 are merged during operation.

[0035] Preferably, both the first semicircular ring 521 and the second semicircular ring 522 are provided with fixing plates 523 ; and the ends of the covering module 51 are connected to the first semicircular ring 521 and the second semicircular ring 522 via the fixing plates 523 .

[0036] In this embodiment, the ends of the covering module 51 are placed on the surfaces of the first semicircular ring 521 and the second semicircular ring 522, and the ends of the covering module 51 are clamped by the fixing plate 523, thereby connecting the first semicircular ring 521 and the second semicircular ring 522 to the covering module 51. The fixing plate 523 facilitates the replacement of the covering module 51 by the operator, reducing labor intensity.

[0037] Preferably, the covering module 51 is a POM plastic film, a PET plastic film or a filter mesh.

[0038] In this embodiment, the coating module 51 is preferably made of a POM plastic film. POM has high wear resistance and can extend the service life of the coating module 51. Alternatively, a PET plastic film or a filter screen can be used. When using a filter screen, a mesh size that prevents iron impurities from passing through should be selected.

[0039] Preferably, the first semicircular ring 521 is a first semicircular ring 521 made of plastic; and the second semicircular ring 522 is a second semicircular ring 522 made of plastic.

[0040] In this embodiment, the first semicircular ring 521 and the second semicircular ring 522 are both made of plastic, which can avoid affecting the magnetism of the magnetic rod 22 and prevent the first semicircular ring 521 and the second semicircular ring 522 from conducting magnetism, thereby preventing iron impurities from being attracted to the first semicircular ring 521 and the second semicircular ring 522. When the first semicircular ring 521 and the second semicircular ring 522 are opened, iron impurities will not fall into the box body 1.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
