Description

Technical Field

[0001] This utility model relates to the field of magnesium oxide filtration, specifically to a magnesium oxide filtration device. Background Technology

[0002] Magnesium oxide is a common inorganic compound, a white powder or granular substance formed by the combination of magnesium and oxygen. It has extremely high melting and boiling points, excellent high-temperature resistance, and is almost insoluble in water. It is highly adaptable and has wide applications in metallurgy, building materials, electronics, environmental protection, medicine and other fields.

[0003] For example, in electronic fibers, magnesium oxide is often used as an insulating or coating layer to protect the safety and durability of the electronic fibers and improve their heat resistance and flame retardant properties. However, during the production of magnesium oxide, large particles, metal shavings, and insufficiently crushed lumps are easily mixed into the magnesium oxide raw materials during crushing, grinding, and transportation. If these impurities are not treated, they will affect the purity and quality of the product.

[0004] However, in existing magnesium oxide filtration devices, free-fall feeding is usually used, with the magnesium oxide raw material falling from top to bottom onto the screen surface. This causes a large amount of falling magnesium oxide raw material to easily accumulate and impact the filter screen, reducing the filter screen's lifespan and also causing uneven load on the filter screen surface, thus reducing the filtration effect.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0012] Furthermore, in order to achieve multi-stage filtration, the diameter of the filter holes on the first filter plate is larger than the diameter of the filter holes on the second filter plate.

Detailed Implementation

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a filtration device for magnesium oxide is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-6 As shown, the magnesium oxide filtration device according to an embodiment of the present invention includes a filter box 1; a control panel 2, disposed on one side of the filter box 1; a feeding assembly 3, disposed at the top of the filter box 1, for buffering the falling magnesium oxide raw material; a filtration assembly 4, disposed inside the filter box 1, for multi-layer filtration of the magnesium oxide raw material; a vibration motor 5, disposed at the bottom center of the filter box 1; and a support frame 6, disposed at the bottom of the filter box 1.

[0022] Using the aforementioned technical solution, the feeding component 3, through the long strip plate under the action of the fan-shaped magnet, adsorbs ferrous impurities, achieving initial separation of magnesium oxide raw material from impurities. This improves the efficiency of subsequent filtration stages and the quality of the finished product, avoids wear on the filter plate caused by metallic impurities, and prevents the concentrated impact of magnesium oxide raw material from causing accumulation or blockage, thus enhancing the continuous operation capability of the device. Under the action of the filter component 4, the magnesium oxide raw material undergoes multiple filtrations, achieving a step-by-step separation from coarse to fine filtration. This improves the filtration accuracy and the uniformity of the finished product particles. Simultaneously, the scraper cleans the filter plate, reducing the blockage rate and extending the continuous working time of the equipment.

[0023] It should be noted that the vibration motor 5 consists of a motor, a rotor shaft, and eccentric blocks. When the motor is powered on, the rotor shaft of the motor begins to rotate at high speed. Since eccentric blocks with asymmetrical mass are installed at both ends of the rotor shaft, when these eccentric blocks rotate at high speed with the shaft, a strong centrifugal force is generated, and the entire motor generates high-frequency vibration, which in turn drives the filter box 1 to vibrate. This is existing technology and will not be elaborated on here.

[0024] Furthermore, in specific implementation, the first motor 316, the second motor 4073, and the vibration motor 5 are electrically connected to the control panel 2. The start command is issued through the human-machine interface (HMI) of the control panel 2. This signal is transmitted from the HMI to the PLC programmable logic controller. After receiving the command, the PLC controls the first motor 316, the second motor 4073, and the vibration motor 5 to rotate and operate synchronously according to preset data, making precise operations on the magnesium oxide filtration operation and ensuring that various operations are carried out accurately. This is existing technology and will not be elaborated on further here.

[0025] In one embodiment, the feeding assembly 3 includes a housing 301 disposed at the top of the filter box 1. The top of the housing 301 has a feeding port 302, and the bottom of the housing 301 has a discharge port 303 and a waste discharge port 304 arranged sequentially, with a separator 305 between the discharge port 303 and the waste discharge port 304. A protective shell 306 is disposed on one side of the housing 301. A fixed roller 307 is disposed on one side of the inner side of the housing 301. A sector magnet 308 is fixedly disposed on the outer side of the fixed roller 307. A rotating drum 309 is disposed on the outer side of the sector magnet 308. Several long strips 310 are disposed on the outer side of the rotating drum 309. A bearing 311 is disposed between the inner end of one end of the rotating drum 309 and the outer side of the fixed roller 307. The other end of the rotating drum 309 is provided with a rotating shaft 312 that passes through the outer shell 31. The rotating shaft 312 and the outer shell 301 are connected by a bearing. A first gear 313 is provided on the outside of the rotating shaft 312. A second gear 315 that meshes with the first gear 313 is provided on the outside of the first gear 313. A first motor 316 that drives the second gear 315 is provided on one side of the protective shell 306. This realizes the initial separation of magnesium oxide raw material and impurities, and improves the efficiency of subsequent filtration and the quality of finished product.

[0026] It should be noted that, in order to ensure the normal rotation of the rotating drum 309, the rotating drum 309 can be made of non-magnetic materials such as stainless steel. The sector magnet 308 needs to generate a strong attraction to capture iron impurities, and can be made of permanent magnet materials such as neodymium iron boron.

[0027] The working principle of the feeding component 3 is as follows: First, when the magnesium oxide raw material to be filtered enters the housing 301 through the feeding port 302, the operator starts the first motor 316 through the control panel 2. Driven by the first motor 316, the rotating drum 309 and the long plate 310 are rotated. When the magnesium oxide raw material falls on the surface of the long plate 310, under the action of the fan magnet 308, the iron impurities in the magnesium oxide raw material are firmly adsorbed onto the long plate 310. Under the rotation of the rotating drum 309, the magnesium oxide raw material without iron impurities enters the filter box 1 through the discharge port 303, while the impurities continue to rotate under the action of the rotating drum 309. When the impurities rotate to the back of the fan magnet 308, the attraction decreases, and under the action of gravity, the impurities are discharged through the impurity discharge port 304.

[0028] In one embodiment, the filter assembly 4 includes a first filter plate 401 and a second filter plate 402 arranged sequentially from top to bottom within the filter box 1. The surfaces of the first filter plate 401 and the second filter plate 402 are provided with filter holes 403. A first discharge plate 404 is provided on one side of the first filter plate 401, and a second discharge plate 405 is provided on one side of the second filter plate 402. A third discharge plate 406 connected to the filter box 1 is provided below the second discharge plate 405. A cleaning member 407 is provided between the bottom end of the first filter plate 401 and the top end of the second filter plate 402. The cleaning component 407 includes a protective frame 4071 located on the other side of the filter box 1. A lead screw 4072 is installed inside the protective frame 4071. One end of the lead screw 4072 passes through the side wall of the protective frame 4071 and is fitted with a second motor 4073. Several protective brushes 4074 are installed at the top and bottom of the inner side of the protective frame 4071. A sliding block 4075 is installed on the outer side of the lead screw 4072. A limiting strip 4076 is installed on one side of the inner wall of the protective frame 4071. A limiting groove 4077 that mates with the limiting strip 4076 is provided on one side of the sliding block 4075. A connecting block 4078, which has a T-shaped structure, is installed on the other side of the sliding block 4075. Scrapers 4079 are installed at the top and bottom of the connecting block 4078. The diameter of the filter holes 403 on the first filter plate 401 is larger than the diameter of the filter holes 403 on the second filter plate 402, which enables multiple filtrations of magnesium oxide raw materials and achieves step-by-step separation from coarse filtration to fine filtration, thereby improving the filtration accuracy and the uniformity of the finished particles and extending the continuous working time of the equipment.

[0029] It should be noted that, in order to protect the lead screw 4072 from the intrusion of impurities, the protective brush 4074 uses a safety brush, and the aforementioned safety brush can be a similar brush used in escalators, which is existing technology and will not be elaborated on here. The protective brush 4074 in this device plays a role in hindering magnesium oxide and impurities, preventing impurities from adhering to the lead screw 4072, thereby avoiding the lead screw 4072 being blocked by impurities and causing the cleaning part 407 to be stuck.

[0030] The working principle of the filter assembly 4 is as follows: When the magnesium oxide raw material after preliminary filtration falls into the filter box 1, it first falls onto the first filter plate 401. Large particles of impurities are intercepted and discharged along the first discharge plate 404. Smaller particles of impurities pass through the filter holes 403 of the first filter plate 401 and then fall onto the second filter plate 402 to achieve secondary filtration, further intercepting medium-sized particles of impurities. Qualified magnesium oxide falls through the second filter plate 402 to the third discharge plate 406 for discharge. When it is necessary to clean the top of the second filter plate 402 and the bottom of the first filter plate 401, the operator sends a start command to the second motor of the control panel 2. Upon receiving the start signal, the second motor 4073 drives the lead screw 4072 to rotate, which in turn drives the sliding block 4075 and the scraper 4079 to move and clean between the two filter plates.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical application, firstly, the operator feeds the magnesium oxide raw material to be filtered into the interior of the housing 301 through the feed port 302. Then, the first motor 316 is started, and the magnesium oxide raw material is initially filtered through the cooperation of the long plate 310 and the fan-shaped magnet 308 (the working principle of the feed assembly 3 is as described above). Next, the pre-filtered magnesium oxide raw material falls onto the first filter plate 401 in the filter box 1. Under the vibration of the vibration motor 5, impurities with a particle diameter smaller than the filter holes 403 on the first filter plate 401 are discharged and collected through the first discharge plate 404. The filtered magnesium oxide raw material then falls onto the second filter plate 402 (the working principle of the filter assembly 4 is as described above). Finally, the filtered magnesium oxide raw material is discharged and collected through the third discharge plate 406. When it is necessary to clean the first filter plate 401 and the second filter plate 402, the operator pauses the vibration motor 5 through the control panel and then starts the second motor 4073 to drive the scraper 4079 for cleaning.

[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, the feeding component 3, under the action of the sector magnet 308, adsorbs ferrous impurities through the long strip plate 310, achieving preliminary separation of magnesium oxide raw material from impurities. This improves the efficiency of subsequent filtration processes and the quality of the finished product, avoids wear on the filter plate caused by metallic impurities, and prevents the concentrated impact of magnesium oxide raw material from causing accumulation or blockage, thus enhancing the continuous operation capability of the device. Under the action of the filter component 4, the magnesium oxide raw material undergoes multiple filtrations, achieving a step-by-step separation from coarse to fine filtration, improving the filtration accuracy and the uniformity of the finished product particles. Simultaneously, the scraper 4079 cleans the filter plate, reducing the blockage rate and extending the continuous working time of the equipment.
