Description

Technical Field

[0001] This utility model relates to the field of line protection technology for iron separators, and in particular to a line protection component for a dry electromagnetic iron separator. Background Technology

[0002] The function of the line protection component of a dry electromagnetic separator is to protect the excitation coil and ensure the safe and stable operation of the equipment. When the electromagnetic separator is working, it generates a strong magnetic field. The line protection component can prevent electrical faults, such as short circuits or overloads, which may lead to safety accidents or equipment damage.

[0003] Dry electromagnetic separators use electromagnets with wound wires installed inside the separator to remove iron. Existing separators are usually installed on other transport devices and used in conjunction with these devices to screen out metal from the material. However, during operation, electromagnetic separators may encounter problems such as poor contact or detachment of the internal electromagnetic coils, which is detrimental to improving the stability of the separator. Therefore, this utility model proposes a circuit protection component for a dry electromagnetic separator. Utility Model Content

[0006] The fixing assembly includes a fixed outer shell and a rotating shaft. The fixed outer shell is fixedly connected to the protective outer shell. A fixing plate is provided inside the protective outer shell on the side near the fixed outer shell. A second sliding groove is provided inside the protective outer shell on the side near the fixing plate. A moving rod is fixedly connected to the fixing plate on the side near the second sliding groove. The moving rod is slidably connected to the second sliding groove. The rotating shaft is slidably connected inside the fixed outer shell. A slider is fixedly connected to the rotating shaft on the side near the moving rod.

[0007] A fixing block is fixedly connected to the bottom end of the rotating shaft, and a rubber block is fixedly connected to the fixing block.

[0008] Preferably, a first sliding groove is provided on the side of the fixed housing near the slider, the first sliding groove is connected to a second sliding groove, and the slider is slidably connected to the first sliding groove.

[0009] In a preferred embodiment, by connecting slide groove one and slide groove two, the moving rod contacts the slider inside slide groove one through slide groove two, thereby causing the slider to push the moving rod.

[0010] Preferably, a connecting block is fixedly connected to the top of the protective shell, and a heat sink is fixedly connected to the side of the protective shell near the fixed shell.

[0011] As a preferred embodiment, by installing the connecting block on the protective housing, it is convenient to connect the external mechanical device to the protective housing, thereby making the dry electromagnetic separator easy to install. The heat sink is evenly installed on it, so that the heat sink can easily dissipate the heat inside the protective housing, avoiding overheating inside the protective housing, which could lead to problems such as fuse blowing, short circuit, and switch damage.

[0012] Preferably, the bottom component includes a base plate and a base. The base plate is disposed at the bottom of the protective shell and is fixedly connected to a metal block. The base is fixedly connected to the side of the base plate near the fixed shell. A second fixing block is fixedly connected to the side of the base near the first fixing block. A snap-fit ​​groove is provided on the side of the second fixing block near the rubber block. The second fixing block is fixedly connected to the first fixing block through the snap-fit ​​groove and the rubber block.

[0013] In a preferred embodiment, by rotating the shaft, the fixing block one at the bottom of the shaft is rotated to the bottom of the fixing block two, so that fixing block one and fixing block two cooperate to fix the protective shell on the base plate, thereby facilitating the disassembly and assembly of the iron separator, making it easier for workers to maintain its internal parts, and making it easier to check whether there are damaged or aged parts inside the iron separator and replace them in time.

[0014] Preferably, a sealing groove is provided on the side of the protective shell near the bottom plate, and a sealing gasket is provided on the side of the bottom plate near the sealing groove.

[0015] As a preferred embodiment, by installing the sealing gasket on the base plate, the sealing gasket seals the inside of the sealing groove, thereby preventing dust and moisture from entering the interior of the protective housing, which is beneficial for further protecting the internal circuitry of the iron separator.

[0016] Preferably, a sliding groove three is provided on the side of the fixing block two near the snap-fit ​​groove, and the fixing block two is slidably connected to the fixing block one through the sliding groove three.

[0017] In a preferred embodiment, by rotating the first fixing block, the first fixing block drives the rubber block to move along the third sliding groove to the inside of the locking groove, so that the first fixing block engages with the second fixing block.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting a fixed component, rotating the rotating shaft, the rotating shaft drives the slider to rotate along the first slide groove, causing the slider to push the moving rod to move inside the second slide groove, causing the moving rod to push the fixed plate towards the metal block, and causing the fixed plate to fix the wire wound on the metal block, thereby avoiding the situation that the internal electromagnetic coil may have poor contact or fall off during the operation of the magnetic separator, and improving the stability of the electromagnet.

[0020] 2. In this utility model, by setting a fixing component and a bottom component, when the rotating shaft rotates and the fixing plate fixes the line, fixing block one moves to the bottom of fixing block two along with the rotating shaft. At this time, the rubber block on fixing block one is squeezed. Since the rubber block is elastic, the rubber block is compressed inside the slide groove three and moves along the slide groove three to the inside of the snap-fit ​​groove, thereby fixing fixing block one and fixing block two. Reverse rotation of the rotating shaft can remove the protective shell, which makes it convenient for workers to maintain its interior frequently, and to check whether there are damaged or aged parts inside the iron remover, and replace them in time.

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Please see Figures 1-5 This utility model provides a technical solution: a circuit protection component for a dry electromagnetic iron separator, comprising: a protective shell 1, a fixing component 2, and a bottom component 3. The fixing component 2 is disposed on the protective shell 1, and the bottom component 3 is disposed on the bottom of the protective shell 1. A metal block 5 is disposed on the side of the bottom component 3 near the inside of the protective shell 1.

[0034] like Figure 2 and Figure 3 As shown, the fixing component 2 includes a fixing housing 21 and a rotating shaft 22. The fixing housing 21 is fixedly connected to the protective housing 1. A fixing plate 23 is provided inside the protective housing 1 on the side near the fixing housing 21. A second sliding groove 27 is provided inside the protective housing 1 on the side near the fixing plate 23. A moving rod 24 is fixedly connected to the fixing plate 23 on the side near the second sliding groove 27. The moving rod 24 is slidably connected to the second sliding groove 27. The rotating shaft 22 is slidably connected inside the fixing housing 21. A slider 25 is fixedly connected to the rotating shaft 22 on the side near the moving rod 24.

[0035] A fixing block 28 is fixedly connected to the bottom of the rotating shaft 22, and a rubber block 29 is fixedly connected to the fixing block 28. By winding the wire around the metal block 5 and energizing the wire, the metal block 5 becomes magnetic, thereby attracting metal. A handle is installed on the top of the rotating shaft 22. Pulling the handle rotates the rotating shaft 22, causing the slider 25 on the rotating shaft 22 to rotate. Since the slider 25 has an arc-shaped structure, the width of one end is smaller than the width of the other side. When the slider 25 rotates, the narrower end gradually moves away from the moving rod 24, and the wider end gradually moves closer to the moving rod 24. This causes the slider 25 to drive the moving rod 24 to slide inside the slide groove 27, and the moving rod 24 pushes the fixing plate 23 towards the metal block 5. The fixing plate 23 then presses the wire wound on the metal block 5, fixing the wire to the metal block 5. This solves the problem of poor contact or detachment of the internal electromagnetic coil that may be encountered during the operation of the magnetic separator, and improves the stability of the electromagnet.

[0036] Furthermore, such as Figure 3 As shown, a first groove 26 is provided on the side of the fixed housing 21 near the slider 25. The first groove 26 is connected to the second groove 27. The slider 25 is slidably connected to the first groove 26. By connecting the first groove 26 and the second groove 27, the moving rod 24 contacts the slider 25 inside the first groove 26 through the second groove 27, thereby causing the slider 25 to push the moving rod 24.

[0037] The above solution also has the problem of overheating inside the protective casing 1 due to prolonged use of the iron separator. Figure 1 As shown, a connecting block is fixedly connected to the top of the protective housing 1, and a heat sink 4 is fixedly connected to the side of the protective housing 1 near the fixed housing 21. By installing the connecting block on the protective housing 1, it is convenient to connect external mechanical devices to the protective housing 1, thereby making it easy to install the dry electromagnetic separator. The heat sink 4 is evenly installed on the protective housing 1, so that the heat sink 4 can easily dissipate the heat inside the protective housing 1, avoiding overheating inside the protective housing 1, which could lead to problems such as fuse blowing, short circuit, and switch damage.

[0038] The above solution also suffers from the problem that the magnetic separator is difficult to disassemble and assemble, making maintenance inconvenient. Figure 4 As shown, the bottom component 3 includes a base plate 31 and a base 32. The base plate 31 is located at the bottom of the protective shell 1 and is fixedly connected to the metal block 5. The base 32 is fixedly connected to the base plate 31 on the side near the fixed shell 21. A second fixing block 33 is fixedly connected to the side of the base 32 near the first fixing block 28. A snap-fit ​​groove 34 is provided on the side of the second fixing block 33 near the rubber block 29. The second fixing block 33 is fixedly connected to the first fixing block 28 through the snap-fit ​​groove 34 and the rubber block 29. By rotating the rotating shaft 22, the first fixing block 28 at the bottom of the rotating shaft 22 is rotated to the bottom of the second fixing block 33, so that the first fixing block 28 and the second fixing block 33 cooperate to fix the protective shell 1 to the base plate 31, thereby facilitating the disassembly and assembly of the iron separator, making it easier for workers to maintain its internal parts, check for damaged or aged parts inside the iron separator, and replace them in time.

[0039] Furthermore, a sealing groove 6 is provided on the side of the protective housing 1 near the bottom plate 31, and a sealing gasket 7 is provided on the side of the bottom plate 31 near the sealing groove 6. By installing the sealing gasket 7 on the bottom plate 31, the sealing gasket 7 seals the inside of the sealing groove 6, thereby preventing dust and moisture from entering the inside of the protective housing 1, which is beneficial to further protect the circuit inside the iron remover.

[0040] Furthermore, such as Figure 5As shown, a sliding groove 35 is provided on the side of the fixing block 2 33 near the snap-fit ​​groove 34. The fixing block 2 33 is slidably connected to the fixing block 1 28 through the sliding groove 35. By rotating the fixing block 1 28, the fixing block 1 28 drives the rubber block 29 to move along the sliding groove 35 to the inside of the snap-fit ​​groove 34, so that the fixing block 1 28 snaps into the fixing block 2 33.

[0041] The usage method and working principle of this device are as follows: Figures 1-5 As shown, the metal block 5 is first installed on the base plate 31, and the external wiring is wrapped around the metal block 5. Then the protective shell 1 is placed on top of the base plate 31. At this time, the sealing gasket 7 installed on the base plate 31 is squeezed by the protective shell 1, sealing the sealing groove 6 on the protective shell 1, thereby preventing dust and moisture from entering the interior of the protective shell 1.

[0042] Then, rotate the handle at the top of the rotating shaft 22 and pull the handle to make the rotating shaft 22 rotate. The slider 25 follows the rotating shaft 22 and rotates inside the first slide groove 26, so that the narrower end of the slider 25 gradually moves away from the moving rod 24 and the wider end of the slider 25 gradually moves closer to the moving rod 24. The slider 25 pushes the moving rod 24 to move inside the second slide groove 27, so that the moving rod 24 pushes the fixing plate 23 to move towards the metal block 5, pressing the fixing plate 23 onto the line, thereby fixing the line and avoiding the possibility of poor contact or detachment of the internal electromagnetic coil during the operation of the magnetic separator, thus improving the stability of the electromagnet.

[0043] When the rotating shaft 22 rotates, it drives the first fixing block 28 to rotate to the bottom of the second fixing block 33. At this time, the rubber block 29 on the first fixing block 28 is squeezed by the second fixing block 33. Due to the elasticity of the rubber block 29, the rubber block 29 is squeezed into the inside of the third sliding groove 35 and moves along the third sliding groove 35 with the first fixing block 28 to the inside of the snap-fit ​​groove 34. When the rubber block 29 is inside the snap-fit ​​groove 34, the rubber block 29 returns to its original shape and snaps into the inside of the snap-fit ​​groove 34, thereby fixing the first fixing block 28 and the second fixing block 33. When it is necessary to remove the protective shell 1, it is only necessary to rotate the rotating shaft 22 in the opposite direction. This makes it easier for workers to maintain its interior frequently, check whether there are damaged or aged parts inside the iron remover, and replace them in time.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
