Description

Technical Field

[0001] The present application relates to the field of magnetic separation technology, and in particular to a magnetic separation device. Background Art

[0002] During material processing, magnetic impurities such as iron filings may be introduced into the material due to wear and tear of mechanical equipment or inherent impurities in the raw materials. These magnetic impurities not only reduce the purity of the material but may also cause performance degradation during product use, affecting the overall quality and reliability of the product.

[0003] Currently, the most common method is to use magnets or magnetic racks to absorb magnetic impurities from materials. However, in practice, these traditional devices are unable to fully absorb all the iron filings due to the relatively low magnetic density of the magnets and the limited contact area between the material and the magnet. In addition, when excessive iron filings accumulate on the magnet surface, they may form a shielding effect, further reducing the efficiency of magnetic separation. Utility Model Content

[0024] As mentioned in the Background, materials processing is a common practice in modern industry, encompassing every step from raw materials to final product. Whether it's metals, plastics, or chemical raw materials, optimizing the processing technology directly impacts product quality and production efficiency. Granulation, as a common materials processing technology, is widely used across multiple industries and has become a crucial tool for producing high-quality products.

[0025] Granulation is a process that transforms powdered, granular, or molten materials into granules of a certain shape and size through a specific processing method. Its core is to reorganize materials through physical or chemical methods to improve their physical properties and processing performance.

[0026] Granulation is widely used in the plastics, chemical, pharmaceutical, and agricultural industries. For example, in the plastics industry, granulation can be used to reprocess recycled plastic fragments into granules for subsequent injection molding. In the pharmaceutical field, granulation improves the flowability of drug powders, facilitating capsule filling. This process not only improves material utilization efficiency but also reduces dust pollution during the production process, enhancing production safety.

[0027] During the pelletizing process, the material passes through a series of mechanical equipment, including internal mixers, feeders, twin-screw extruders, single-screw extruders, pelletizers, and vibrating screens. These devices operate under high temperatures, high pressures, and high speeds, causing metal components to wear and produce tiny iron filings. These iron filings, when mixed with the material, not only reduce its purity but can also cause defects during subsequent processing or use, impacting product performance and reliability.

[0028] Currently, magnetic separation technology is commonly used, utilizing magnets or magnetic racks to capture iron filings from materials. However, the magnetic density of conventional magnetic separation equipment is often limited, resulting in insufficient contact area between the material and the magnet, making it impossible to fully capture all the iron filings. Furthermore, excessive accumulation of iron filings on the magnet surface can create a shielding effect, further reducing the efficiency of magnetic separation.

[0029] In view of this, embodiments of the present application provide a magnetic separation device comprising a bin and at least two screening assemblies. The bin provides a closed processing environment for magnetic separation of materials. The screening assemblies include filter plates and multiple magnetic components. The filter plates are detachably connected to the bin. This design allows for quick replacement of filter plates of varying specifications based on different processing requirements, enabling the magnetic separation device to flexibly adapt to the characteristics of different materials and enhancing its versatility and adaptability. The magnetic components utilize their powerful magnetic force to attract magnetic impurities such as iron filings from the material. Each magnetic component is detachably connected to the filter plates. This allows for selecting the appropriate magnetic component and filter plate combination based on the properties and content of magnetic impurities in the material to optimize the magnetic separation effect. Furthermore, multiple screening assemblies can be provided, spaced apart axially along the bin, allowing the material to pass through the filter plates layer by layer as it falls, thereby increasing the contact time and area between the material and the magnetic components. Through multi-layer magnetic separation, the magnetic separation device can significantly improve the removal efficiency of magnetic impurities such as iron filings, enhance the magnetic separation effect, and thus significantly improve the purity and quality of the material.

[0030] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in 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. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] Figure 1 This is a schematic diagram of the structure of the magnetic separation device provided in the embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a magnetic separation device 10. The magnetic separation device 10 can be widely used in industries such as plastics and rubber processing, food processing, chemical and pharmaceutical industries, and renewable resources. In these fields, the magnetic separation device 10 can effectively remove iron filings or other magnetic impurities that are mixed into the production process, ensuring the purity and performance of the product.

[0032] Reference Figure 1 As shown, the magnetic separation device 10 includes a silo 100. The silo 100, as the main structure of the magnetic separation device 10, can be used to accommodate materials to be processed. To ensure the stability and effectiveness of the magnetic field, the silo 100 can be made of non-magnetic materials to avoid interference with the magnetic field. In addition, the shape of the silo 100 can be set to cylindrical, rectangular, or other forms suitable for specific applications according to specific application requirements, adapting to different industrial environments and material characteristics, and providing higher operating efficiency and effectiveness.

[0033] The magnetic separation device 10 further includes a screening assembly 200, which includes at least two groups of screening assemblies 200. The screening assemblies 200 can be arranged at intervals along the axial direction of the bin body 100. This arrangement can ensure that the material is gradually screened during the flow process. This gradual screening process can increase the contact time and contact area between the material and the screening assembly 200, improve the screening accuracy and efficiency, and ensure that the material can be fully magnetically separated when passing through each group of screening assemblies 200.

[0034] Specifically, the screening assembly 200 includes a filter plate 210 having a plurality of filter holes 211 arranged in an array, through which material can pass. The diameter of the filter holes 211 can be varied to meet specific production requirements. By adjusting the diameter of the filter holes 211, products of varying specifications and qualities can be produced to meet diverse production needs, enabling rapid switching of product lines, thereby improving production efficiency, reducing downtime, and optimizing resource utilization.

[0035] The filter plate 210 is detachably connected to the chamber 100. This detachable design allows for quick replacement of filter plates 210 of varying specifications based on varying processing requirements, enabling the magnetic separation device 10 to flexibly adapt to the characteristics of different materials, thereby enhancing the versatility and adaptability of the magnetic separation device 10. Furthermore, the detachable design allows for timely replacement of the filter plate 210 if it becomes worn or damaged, thus minimizing impact on the overall device, reducing maintenance costs, and improving the reliability and continuous operation of the magnetic separation device 10.

[0036] For example, corresponding bolt holes may be designed on the edge of the filter plate 210 and the inner wall of the silo body 100 , so that the filter plate 210 is firmly fixed in the silo body 100 by fastening with bolts and nuts.

[0037] Alternatively, a buckle may be provided on the inner wall of the bin body 100 and a buckle groove may be provided on the edge of the filter plate 210. The fast installation and removal of the filter plate 210 may be achieved through the cooperation of the buckle and the buckle groove to improve the operation efficiency.

[0038] Of course, a clamp can also be used to secure the filter plate 210 to the inner wall of the bin body 100. The clamp connection allows for quick installation and removal of the filter plate 210 without tools, and is suitable for applications requiring frequent replacement or adjustment of the filter plate 210. This embodiment does not impose any specific limitations as long as a detachable connection between the filter plate and the bin body can be achieved.

[0039] Because the filter plate is subject to continuous impact and abrasion from materials during use, the filter plate 210 can be made of a durable material to ensure stable performance and a long service life even under high-intensity and complex operating conditions. For example, the filter plate 210 can be made of a material with excellent mechanical strength and wear resistance, such as stainless steel, tungsten carbide, or a ceramic composite material.

[0040] In one possible embodiment, the aperture of the filter holes 211 of each filter plate 210 can be reduced in sequence from the top of the silo 100 to the bottom of the silo 100. In this way, the larger aperture at the upper end allows a larger flow of material to enter the silo 100, which helps to quickly process a large amount of material. As the material flows downward, the aperture gradually decreases, which helps to control the flow rate and allows the material to have a longer residence time in the silo 100, thereby improving the adsorption efficiency of the magnetic member 220 on magnetic impurities. In addition, the gradually decreasing aperture can prevent excessive accumulation of material in the silo 100, which is conducive to maintaining the stability and efficient operation of the magnetic separation device.

[0041] It should be noted that although the aperture of the filter hole 211 on the bottom filter plate 210 is the smallest, it still needs to be larger than the minimum size of the material to ensure that all materials can pass through smoothly.

[0042] Alternatively, the pores 211 of each filter plate 210 can maintain a consistent aperture from the top to the bottom of the silo 100. Maintaining a consistent aperture ensures uniform flow of material within the silo 100, avoiding uneven flow rates caused by variations in aperture. Furthermore, the uniform aperture design eliminates the need to distinguish between filter plates 210 at different locations, allowing operators to more quickly and efficiently repair and replace the filter plates 210.

[0043] Continue to refer to Figure 1 As shown, the screening assembly 200 further includes a plurality of magnetic members 220. The magnetic members 220 can absorb magnetic impurities in the material, thereby ensuring the purity of the material and improving the quality of subsequent processing.

[0044] The magnetic part 220 is detachably connected to the filter plate 210. The operator can flexibly adjust the configuration of the screening component 200 according to the different properties and contents of magnetic impurities in the material, and select the most suitable combination of the magnetic part 220 and the filter plate 210 to optimize the magnetic separation effect and meet the diverse needs of production.

[0045] For example, each magnetic member 220 can be secured to the filter plate 210 via a snap or clamp. Alternatively, a slide groove can be provided on the filter plate 210, allowing the magnetic member 220 to be slidably mounted on the filter plate 210, thereby flexibly adjusting the position of the magnetic member 220. The present embodiment does not specifically limit the mounting method of the magnetic member 220.

[0046] Specifically, magnetic members 220 can be spaced between the filter holes 211 of the filter plate 210. This arrangement helps capture and separate iron filings or other magnetic impurities in the material. Furthermore, the spacing of magnetic members 220 ensures smooth flow of material through the filter plate 210 while minimizing residual magnetic impurities and preventing them from clogging the filter holes 211, thereby extending the service life of the filter plate 210.

[0047] In one possible embodiment, magnetic member 220 can be attached to the top surface of filter plate 210 to attract magnetic impurities before the material enters the filter holes. This significantly reduces the risk of filter holes 211 becoming clogged, helps maintain the permeability of filter plate 210, and ensures continuous and efficient material flow.

[0048] Of course, magnetic member 220 can also be attached to the bottom surface of filter plate 210, allowing the material to pass through filter plate 210 and then absorb magnetic impurities in the material. This arrangement can provide a certain buffering effect on the material after passing through filter holes 211, reducing the material flow rate. This can enhance the screening and absorption effect of magnetic member 220 on magnetic impurities.

[0049] Alternatively, the magnetic member 220 may be configured as a columnar member and may be positioned vertically on the filter plate 210. The columnar design allows the magnetic member 220 to provide a larger surface area within a limited space, thereby increasing the adsorption capacity of magnetic impurities and improving magnetic separation capabilities. The vertical arrangement minimizes the obstruction of the magnetic member 220 to the flow of material, maintaining smooth material flow, reducing flow resistance, and preventing material blockage, thereby improving the efficiency of the magnetic separation device 10.

[0050] For example, magnetic member 220 can be configured as a cylindrical member. The outer surface of the cylindrical member adopts a circular arc transition to ensure that there are no sharp edges or corners. Thus, when magnetic member 220 contacts the material, the smooth surface can reduce physical damage to the material, minimize friction and wear, and thus ensure the integrity and quality of the material.

[0051] Continue to refer to Figure 1As shown, the silo 100 is also provided with an access port (not shown) that is openably located on the side wall of the silo 100. During normal operation, the access port remains securely closed to prevent material leakage or external contaminants from entering the silo 100, ensuring a clean and safe production environment. When the filter plate 210 needs to be installed or removed, the access port can be opened to provide access. Furthermore, the access port allows for routine equipment maintenance, troubleshooting, and component replacement, enabling rapid adjustments and cleaning during the production process.

[0052] In addition, the silo 100 further includes an inlet 110 and an outlet 120. The inlet 110 is located at the top of the silo 100, and the outlet 120 is located at the bottom of the silo 100. After entering through the inlet 110, the material naturally falls under the action of gravity, passes through the screening assembly 200, completes magnetic separation, and then flows out through the outlet 120.

[0053] Of course, in order to achieve precise control of the material discharge process, a valve (not shown in the figure) can be provided at the discharge port 120. The valve can be a gate valve, a butterfly valve, or a ball valve, etc., and this embodiment does not impose any specific restrictions on this.

[0054] In one possible embodiment, the silo 100 may further include an air inlet 130 and an air outlet (not shown) to achieve efficient material handling and airflow control. The air inlet 130 may be located at the feed inlet 110. This allows the material to enter the silo 100 smoothly through airflow, aided by airflow. Furthermore, the airflow system ensures uniform distribution of the material upon entry into the silo 100, optimizing subsequent processing. Furthermore, the airflow helps the material pass quickly through the screening assembly 200, reducing retention time and improving production efficiency.

[0055] The air outlet is provided at the top of the silo 100 to help discharge excess gas and dust, maintaining the cleanliness and pressure balance inside the silo 100. For example, the air outlet can be covered with a filter to prevent external dust, particles, and other impurities from entering the silo 100, thereby protecting the purity of the materials in the silo 100 and the normal operation of the equipment.

[0056] The various embodiments or implementation methods in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referenced to each other.
