Description

Technical Field

[0001] This application relates to the field of impurity separation equipment technology, and in particular to an automatic iron remover. Background Technology

[0002] In the continuous production of powder and granular materials, the contamination of impurities with iron can lead to equipment wear, reduced product quality, and even safety hazards. Therefore, automatic iron separators are widely used in the industry to separate magnetic impurities from materials. Among existing technologies, the grid-type automatic iron separator is widely used due to its high degree of automation and the fact that it does not require production shutdowns for cleaning. Its typical structure includes a magnetic bar grid, a housing, a cleaning plate, a PLC control system, and a drive unit. The PLC program controls the extension of the magnetic bars, and a scraper removes the iron filings adsorbed on the surface of the magnetic bars, thus achieving iron removal. However, the existing technology often uses a single scraper to remove the iron filings adsorbed by the magnetic bars. This requires the scraper and multiple magnetic bars to maintain a high degree of coaxiality. When the number of magnetic bars increases, installation misalignment can easily cause the scraper to jam, affecting the normal operation of the equipment. At the same time, the strong magnetic bars, arranged in a small space within the housing, are prone to mutual attraction, leading to magnetic bar misalignment or increased driving resistance, causing equipment failure.

[0003] To address the aforementioned issues, there is an urgent need for a stable and reliable automatic iron remover to meet the demands of continuous production with high adaptability and reliability. Utility Model Content

[0004] The main objective of this application is to provide an automatic iron separator, which aims to solve the technical problem that existing iron separators are prone to jamming due to the strong correlation of their structures.

[0005] To achieve the above objectives, this application proposes an automatic iron separator, comprising:

[0006] A housing, the housing including an inlet, an outlet and at least one set of cleaning ports;

[0007] A magnetic rod layer assembly is disposed in the inner cavity of the housing, with one end extending out of the housing from the cleaning port. The magnetic rod layer assembly includes at least one layer of magnetic rod grid composed of several magnetic rods arranged in parallel. Each magnetic rod is fitted with an independent floating scraper ring, which scrapes off the iron filings adsorbed on the magnetic rods when the magnetic rods move out of the housing.

[0008] For example, in at least one embodiment of the automatic iron remover provided in this application, the automatic iron remover further includes a chip discharge port, which is provided in correspondence with at least one set of cleaning ports for receiving iron chips hanging from the magnetic rod and discharging them outside the housing.

[0009] For example, in the automatic iron remover provided in at least one embodiment of this application, the outer diameter of each floating scraper ring is larger than the corresponding cleaning port, or each floating scraper ring matches the size of the corresponding cleaning port and is fitted onto the cleaning port.

[0010] For example, in the automatic iron remover provided in at least one embodiment of this application, the spacing between adjacent magnetic rods is fixed at both ends of at least one layer of the magnetic rod grid by a magnetic rod fixing plate.

[0011] For example, in the automatic iron remover provided in at least one embodiment of this application, the magnetic rod fixing plate located in the inner cavity of the housing is provided with a groove, and the inner cavity of the housing is also provided with at least one guide rail, the groove and the guide rail cooperating to restrict the relative position between multiple magnetic rod grids.

[0012] For example, in the automatic iron remover provided in at least one embodiment of this application, the housing is provided with a buffer on the inner cavity between the feed inlet or the feed inlet and the magnetic rod layer assembly to disperse the impact force of the material.

[0013] For example, in the automatic iron remover provided in at least one embodiment of this application, the buffer is a flat or grid-like array structure.

[0014] For example, in the automatic iron remover provided in at least one embodiment of this application, the automatic iron remover further includes a drive assembly. The drive assembly is disposed on at least one side of the magnetic rod layer assembly and includes a plurality of linear drive members corresponding to the number of magnetic rod grid layers. The distal end of each linear drive member is installed and connected to a magnetic rod fixing plate located outside the housing, and drives the magnetic rod grid to move linearly into or out of the inner cavity of the housing.

[0015] For example, in the automatic iron remover provided in at least one embodiment of this application, the linear drive is a cylinder, a hydraulic cylinder, an electric push rod, or a lead screw driven by a motor.

[0016] For example, in at least one embodiment of the automatic iron remover provided in this application, the automatic iron remover further includes a dust cover disposed on one side of the housing for covering the exposed portions of each magnetic bar grid that have moved out of the housing.

[0017] The automatic iron remover of this application has at least the following beneficial effects: by setting an independent floating scraper ring on each magnetic rod, the iron filings adsorbed by the magnetic rod can be scraped off in the housing by the floating scraper ring. The parallel magnetic rod grid and the layered magnetic rod layer assembly also have fault tolerance in realizing their functions due to the relatively independent floating scraper ring. For example, there is no need for strict and high-precision dimensional design and processing. The automatic iron remover solution of this application systematically solves the problems of poor sealing, easy jamming and difficult maintenance of traditional automatic iron removers, and at the same time provides a structural basis for the protection of magnetic rods.

[0030] Example 1

[0031] like Figure 1 As shown, the automatic iron remover includes a housing 10, a magnetic rod layer assembly 20, a chip discharge port 30, and a drive assembly 40; wherein, the housing 10 includes a feed port 11 at the top, a discharge port 12 at the bottom, and a cleaning port 13 on the side. The cleaning ports 13 are divided into upper and lower groups, with the upper group having 5 cleaning ports 13 and the lower group having 6 cleaning ports 13.

[0032] Combination Figure 1 See Figure 2 , Figure 3 and Figure 4The magnetic rod layer assembly 20 is disposed in the inner cavity of the housing 10, with one end extending out of the housing 10 from the cleaning port 13. The magnetic rod layer assembly 20 includes two layers of magnetic rod grids composed of multiple parallel magnetic rods. The two layers of magnetic rod grids are distributed in parallel form inside the housing 10, namely the upper magnetic rod grid 21 and the lower magnetic rod grid 22. Each magnetic rod is fitted with an independent floating scraper ring 23. The two layers of magnetic rod grids are fixed at both ends by magnetic rod fixing plates. For ease of explanation, the one located inside the housing 10 is the inner fixing plate 24, and the one located outside the housing 10 is the outer fixing plate 25.

[0033] A chip removal port 30 is installed correspondingly outside the cleaning port 13. Similarly, the magnetic rod also passes through the chip removal port 30. Below the chip removal port 30 is an integrally formed open groove, and above it is an open groove formed by the outer wall of the housing 10 and the baffle 31. The two open grooves are connected to form the complete chip removal port 30 in this embodiment. The floating scraper ring 23 is located in the section of the open groove formed by the outer wall of the housing 10 and the baffle 31. The diameter of the cleaning port 13 is slightly larger than the diameter of the magnetic rod.

[0034] The drive assembly 40 includes two linear drive members that are arranged in parallel vertically. Their free ends are connected to the outer fixing plate 25 of the upper magnetic rod grid 21 and the outer fixing plate 25 of the lower magnetic rod grid 22, respectively, thereby driving the upper magnetic rod grid 21 and the lower magnetic rod grid 22 to move into or out of the housing 10.

[0035] When the linear drive unit moves the upper magnetic bar grid 21 and the lower magnetic bar grid 22 out of the housing 10, since the diameter of the cleaning port 13 is slightly larger than the diameter of the magnetic bar, the iron filings, as smaller adsorbents, will follow the magnetic bar out of the housing 10. As the length of the magnetic bar out of the housing 10 increases, the floating scraper ring 23 remains in position under the constraint of the opening groove of the chip discharge port 30, but its relative position on the magnetic bar changes, equivalent to moving from one end of the magnetic bar to the other. During this process, the floating scraper ring 23 will scrape off the iron filings adsorbed on the magnetic bar, causing the iron filings to detach from the magnetic bar and be discharged from the chip discharge port 30. Each magnetic rod has a floating scraper ring 23 that performs the aforementioned scraping of iron filings. These rings operate independently, ensuring that even if the movement of the magnetic rods is not perfectly synchronized due to installation or drive issues, the scraping of iron filings on a single magnetic rod remains unaffected. Simultaneously, each floating scraper ring 23 must abut against the cleaning port 13 during relative movement, forming a dynamic seal with the cleaning port 13 whether the magnetic rod grid is moving out of or into the housing 10, ensuring the airtightness of the housing 10 and preventing material leakage. This automatic iron separator system systematically solves the problems of easy jamming, poor sealing, and difficult maintenance inherent in traditional automatic iron separators, while also providing a structural basis for the protection of the magnetic rods.

[0036] Example 2

[0037] like Figure 1 , Figure 4As shown, in another embodiment provided by this application, the automatic iron remover includes a housing 10, a magnetic rod layer assembly 20, a chip discharge port 30, and a drive assembly 40; wherein, the housing 10 includes a feed inlet 11 at the top, a discharge port 12 at the bottom, and a cleaning port 13 on the side. The cleaning ports 13 are divided into upper and lower groups, with 5 and 6 cleaning ports 13 at the top and bottom, respectively. Of course, different combinations of quantities can be selected and adjusted according to the characteristics of the material (magnetic rod grid spacing).

[0038] Similar to Embodiment 1, the magnetic rod layer assembly 20 is also disposed within the cavity of the housing 10 and extends out of the housing 10 at one end. It includes two layers of magnetic rod grids, parallel magnetic rods corresponding to the number and position of the cleaning ports 13, and motion coordination formed by the connection relationship between the inner fixing plate 24, the outer fixing plate 25, and the drive assembly 40. The difference is that in this embodiment, the floating scraper ring 23 no longer blocks the cleaning ports 13 by means of outer diameter difference, but instead uses a matching shape to fit the cleaning ports 13 to ensure sealing. For example, the floating scraper ring 23 still has a circular edge profile, but the diameter of the cleaning port 13 is slightly larger than or the same as the outer diameter of the floating scraper ring 23. When scraping off iron filings, the floating scraper ring 23 can be inserted into or embedded in the cleaning port 13 to seal the gap between the cleaning port 13 and the magnetic rod. In particular, a limiting element is also provided on the cleaning port 13 to prevent the floating scraper ring 23 from falling out of the cleaning port 13. The limiting element can be a single protrusion or a retaining ring on the inner wall of the cleaning port 13. In addition, the floating scraper ring 23 and the cleaning port 13 can also have other shapes and profiles besides circular, such as square or polygonal. The non-circular edge profile can prevent the floating scraper ring 23 from rotating on the magnetic rod, forming a better seal.

[0039] In particular, combination Figure 2 See Figure 4 In this embodiment, the inner fixing plate 24 in the upper and lower magnetic rod grid 22 structure has a groove 26 at one or both ends. A linear guide rail 15 is set or installed at the corresponding position in the inner cavity of the housing 10. The direction of the guide rail is consistent with the movement direction of the magnetic rod grid. The groove 26 is engaged with the corresponding guide rail. While the magnetic rod grid can move smoothly, it can also form a position restriction between each magnetic rod, preventing the magnetic rod from attracting or repelling each other, causing the movement trajectory to be misaligned, thereby jamming the equipment or reducing the working efficiency of the drive component 40.

[0040] Example 3

[0041] like Figure 1 , Figure 2As shown, in another embodiment of this application, the automatic iron remover includes a housing 10, a magnetic rod layer assembly 20, a chip discharge port 30, and a drive assembly 40. The housing 10 includes a feed inlet 11 at the top, a discharge port 12 at the bottom, and cleaning ports 13 on the sides. The cleaning ports 13 are divided into upper and lower groups, with the number of upper and lower cleaning ports 13 determined as needed. Furthermore, a buffer 14 is provided on the feed inlet 11 of the housing 10 or on the inner cavity between the feed inlet 11 and the magnetic rod layer assembly 20 to disperse the material's impact force. For example, the buffer 14 is a welded steel bar provided on the feed inlet 11 (and similarly between the feed inlet 11 and the magnetic rod layer assembly 20) as shown in the figure. This buffer can replace the magnetic rod in bearing the initial scouring effect of the material, reducing the speed of the material passing through the magnetic rod layer assembly 20 and improving the efficiency of the magnetic rod in adsorbing iron filings. Alternatively, the buffer 14 can be configured as a grid-like array structure to increase the contact area with the material, distribute the force evenly, and achieve a better buffering effect. In particular, the grid-like array structure can be configured with a central ridge so that the material can flow to the edge and fall while scouring the buffer 14, thereby improving the adsorption efficiency of each magnetic rod.

[0042] Similar to Embodiments 1 and 2, the magnetic rod layer assembly 20 is also disposed in the inner cavity of the housing 10 and extends out of the housing 10 at one end. It includes two layers of magnetic rod grids, the interaction with the floating scraper ring 23, the parallel magnetic rods corresponding to the number and position of the cleaning port 13, and the motion coordination formed by the connection relationship between the inner fixing plate 24, the outer fixing plate 25 and the drive assembly 40. The chip discharge port 30 can adopt the structure and position relationship in Embodiment 1, which can form a discharge path for iron chips and also constitute the restriction of the floating scraper ring 23, so as to remove iron chips without generating the risk of material re-contamination. Alternatively, the discharge port 12 can be directly used as the chip discharge port 30. In this embodiment, the separation of iron chips on the magnetic rods and their removal from the housing 10 need to be achieved after the material is unloaded. That is, unloading and chip removal need to be carried out in steps. The chip discharge port 30 structure in Embodiment 1 has better efficiency in use. Therefore, the chip discharge port 30 structure design of this embodiment is preferred.

[0043] The drive assembly 40 includes two vertically parallel linear drive members, whose free ends are respectively connected to the outer fixing plate 25 of the upper magnetic rod grid 21 and the outer fixing plate 25 of the lower magnetic rod grid 22, thereby driving the upper magnetic rod grid 21 and the lower magnetic rod grid 22 to move into or out of the housing 10. Figure 1 , Figure 3 and Figure 5In the automatic iron remover shown, the linear drive component is a cylinder 41, which is installed on both sides of the magnetic rod layer assembly 20 and corresponds to the number of layers of the magnetic rod grid. That is, there are four linear drive components arranged on the left and right sides of the magnetic rod layer assembly 20, one above the other, so that the magnetic rod grid can move smoothly and consistently in the same plane dimension, and can work independently without interfering with each other in the upper and lower layers, adapting to different iron removal needs and improving iron removal efficiency. In addition to the cylinder 41, the linear drive component can also be implemented by a hydraulic cylinder, an electric push rod, or a lead screw driven by a motor, etc. The specific implementation depends on a comprehensive consideration of cost, performance, and usage effect, which will not be elaborated here.

[0044] like Figure 5 As shown, the automatic iron remover also includes a dust cover 50 disposed on one side of the housing 10, used to cover the exposed portions of each magnetic rod grid that have moved out of the housing 10. The dust cover 50 is located on one side of the cleaning port 13 and covers the maximum extent to which the magnetic rod grid has moved out of the housing 10, so that the magnetic rods are not contaminated by other particles and dust in the air after the adsorbed iron filings are removed by the floating scraper ring 23, reducing the possibility of bringing in external pollution when they re-enter the housing 10 for work.
