Description

Technical Field

[0001] This utility model belongs to the field of materials processing technology, and in particular relates to an automatic cleaning electromagnetic iron removal device for removing iron from slurry. Background Technology

[0002] Iron removal from slurries is commonly used in industries such as ceramics, chemicals, and food, where high product purity is required. These industries often use liquid slurries to produce solid products. These slurries are mixtures of solid powders and liquid solvents. However, these solid powders or minerals may contain ferromagnetic impurities. Once processed into finished products, these impurities can affect the quality of the finished product. Due to magnetic forces, they may also cause surface defects, black spots, and other problems, affecting the product's appearance. Conventional iron removal devices mostly use electromagnetic iron removal, but this method still has the following drawbacks in practical use: For example, the utility model with publication number CN205673072U discloses an electromagnetic iron removal machine for ceramic slurry. It uses an electromagnet to adsorb iron filings in the ceramic slurry. When energized, the electromagnet tightly adsorbs the iron filings onto the electromagnetic iron removal membrane. When the power is off, the electromagnet loses its magnetism, and the iron filings can be easily washed away from the electromagnetic iron removal membrane. However, when using electromagnetic iron removal, washing away ferromagnetic impurities by cutting off the power will inevitably cause the slurry being transported (or the ferromagnetic impurities adhering to the surface of the iron removal device) to directly enter the next process, affecting the quality of the slurry in the next process. Moreover, the power-off operation must be stopped, which is time-consuming and labor-intensive. Frequent power-off and power-on operations greatly affect work efficiency and lack the function of cleaning ferromagnetic impurities without stopping the machine. Secondly, the slurry described in the above patent directly enters the electromagnetic iron removal membrane, which will cause a great impact, resulting in unstable slurry flow and easy damage to the electromagnetic iron removal membrane. Secondly, as described in the aforementioned patent, when cleaning impurities on the electromagnetic iron removal membrane, backflow may occur, flushing the impurities into the next process and affecting the quality. Finally, if the slurry is fed from too high a height, it can easily cause splashing. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic cleaning electromagnetic iron removal device for slurry iron removal. By setting up an electromagnetic iron removal component, a processing box, a cleaning pipe, a nozzle, a belt, a magnetic plate one, a magnetic plate two, and a feeding hopper, it solves the problems of not being able to clean the residual ferromagnetic impurities of the iron removal device without stopping the machine, unstable flow of slurry during iron removal, easy backflow when cleaning ferromagnetic impurities, and easy splashing of slurry when feeding.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automatic cleaning type electromagnetic iron removal device for removing iron from slurry, comprising a processing box, a feeding hopper, an electromagnetic iron removal assembly, and a cleaning pipe. The processing box contains the electromagnetic iron removal assembly, which includes a first magnetic roller, a second magnetic roller, and a rotating roller. A belt is fitted around the outer circumference of the first magnetic roller, the second magnetic roller, and the rotating roller, and the outer surface of the belt has equidistantly distributed material troughs. The first magnetic roller, the second magnetic roller, and the rotating roller are arranged in a triangular pattern when viewed from the front, with the first magnetic roller at the highest position, the rotating roller located diagonally below the first magnetic roller and at the lowest height, and the second magnetic roller positioned between the first magnetic roller and the rotating roller. A magnetic plate is fixed in the processing box between the first and second magnetic rollers, and a magnetic plate is fixed in the processing box between the second magnetic roller and the rotating roller. A cleaning pipe is fixed on the inner wall of the processing box above the roller, and nozzles are fixed at equal intervals along the periphery of the cleaning pipe, with the nozzles tilted downwards toward the belt. A feed hopper is fixed on the inner top surface of the processing box.

[0005] Furthermore, symmetrically distributed support legs are fixed on both outer side walls of the processing box, and a support plate is fixed between the four support legs.

[0006] Furthermore, a support base is fixed on the side of the processing box, and a geared motor is fixed on the upper end of the support base. The output shaft of the geared motor is connected to the end of the magnetic roller.

[0007] Furthermore, a feed pipe is fixedly installed through the top of the feed hopper, and the upper end of the feed pipe penetrates through the top surface of the processing box and extends outwards. The bottom surface of the feed hopper is provided with equidistantly distributed material holes.

[0008] Furthermore, a triangular truncated pyramid is fixed on the inner bottom surface of the processing box, and openings are provided on the bottom of the processing box on both sides of the triangular truncated pyramid. A slurry discharge hopper and a magnetic powder discharge hopper are fixed below the two openings respectively. The slurry discharge hopper is located below the magnetic roller two, and the magnetic powder discharge hopper is located below the rotating roller.

[0009] Furthermore, a water inlet pipe is fixed through the end of the cleaning pipe, the nozzle faces the inclined surface of the belt between the magnetic roller one and the rotating roller, and the bottom of the feed hopper faces the inclined surface of the belt between the magnetic roller one and the magnetic roller two.

[0010] Furthermore, the first magnetic plate contacts the inner surface of the belt between the first magnetic roller and the second magnetic roller, and the second magnetic plate contacts the inner surface of the belt between the second magnetic roller and the rotating roller.

[0011] This utility model has the following beneficial effects: This invention solves the problem of the inability to continuously clean residual ferromagnetic impurities from the iron removal device without shutting down the machine by setting up an electromagnetic iron removal component, a processing box, a cleaning pipe, and a nozzle. The slurry is fed into a hopper and transported on a belt. It slides down the belt between magnetic rollers one and two until it enters the slurry discharge hopper. During this process, ferromagnetic impurities in the slurry are adsorbed onto the outer surface of the belt by magnetic plates one and two, leaving only clean slurry to be discharged. This process continues until the belt passes the rotating rollers, where the ferromagnetic impurities are removed. Since the rollers do not have magnetic attraction capabilities, the ferromagnetic impurities adsorbed on the belt will fall off as it passes over the rollers. Even if a small amount remains, as the belt moves from the rollers towards the first magnetic roller, it will pass through the cleaning pipe. The cleaning water output from the cleaning pipe is sprayed out through the nozzles to wash away the remaining ferromagnetic impurities on the belt, causing them to fall off. This completes the cleaning operation without stopping the machine or interrupting it. This allows subsequent belts to continue to be cleaned with the second magnetic roller, the first magnetic plate, and the second magnetic plate to adsorb ferromagnetic impurities, preventing the impurities on the belt from increasing and achieving continuous operation.

[0012] This invention solves the problem of unstable flow of slurry during iron removal by setting up a belt, magnetic plate one, and magnetic plate two. A large number of material troughs are set on the surface of the belt, and the slurry is discharged from the material hole at the bottom of the feed hopper and guided into the corresponding material troughs, so that it is transported evenly. Magnetic plate one can support the belt between magnetic roller one and magnetic roller two, so that it will not be excessively deformed due to the gravity of the slurry. The setting of magnetic plate two ensures that impurities on the belt will not fall off when they are between the rotating roller and magnetic roller two.

[0013] This invention solves the problem of backflow when cleaning ferromagnetic impurities by setting up an electromagnetic iron removal component. The belt between the first magnetic roller and the rotating roller is inclined outward, while the belt between the second magnetic roller and the rotating roller is inclined downward towards the rotating roller. Therefore, even if the cleaning pipe and nozzle spray water for cleaning, the lowest point is the belt outside the rotating roller, so the cleaning water will not flow back and the ferromagnetic impurities will not flow back and will inevitably be discharged from the magnetic powder discharge hopper.

[0014] This invention solves the problem of easy splashing of slurry during feeding by setting up a feeding hopper; the bottom of the feeding hopper is equipped with a large number of material holes for uniform material discharge, and the feeding hopper is close to the belt, so excessive splashing will not occur.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-7 As shown, this utility model is an automatic cleaning type electromagnetic iron removal device for removing iron from slurry, including a processing box 1, a feeding hopper 2, an electromagnetic iron removal assembly 3, and a cleaning pipe 4. The processing box 1 is equipped with the electromagnetic iron removal assembly 3, which includes a magnetic roller 301, a magnetic roller 302, and a rotating roller 303. A belt 304 is fitted around the outer periphery of the magnetic roller 301, the magnetic roller 302, and the rotating roller 303, and the outer surface of the belt 304 is provided with equidistantly distributed material troughs 3041. The first cylinder 301, the second magnetic roller 302, and the rotating roller 303 are arranged in a triangle when viewed from the front. The first magnetic roller 301 is the highest, the rotating roller 303 is located diagonally below the first magnetic roller 301 and is the lowest in height, and the second magnetic roller 302 is positioned between the first magnetic roller 301 and the rotating roller 303. A magnetic plate 305 is fixed in the processing box 1 between the first magnetic roller 301 and the second magnetic roller 302, and a magnetic plate 306 is fixed in the processing box 1 between the second magnetic roller 302 and the rotating roller 303. The inclined surface of the belt 304 between magnetic roller 1 301 and magnetic roller 2 302 is the upper inclined surface 1, the inclined surface of the belt 304 between magnetic roller 2 302 and rotating roller 303 is the lower inclined surface, and the inclined surface of the belt 304 between magnetic roller 1 301 and rotating roller 303 is the upper inclined surface 2. The belt 304 rotates in the direction of magnetic roller 1 301, magnetic roller 2 302, and rotating roller 303. When the slurry enters the electromagnetic iron removal component 3, it first enters the upper inclined surface 1 of the belt 304, and passes through magnetic plate 1 305, magnetic roller 2 302, and magnetic plate 2 306 to adsorb ferromagnetic impurities in the slurry, leaving them on the outer surface of the belt 304 until it passes through the non-magnetic rotating roller 303, at which point the ferromagnetic impurities fall off. A cleaning pipe 4 is fixed on the inner wall of the processing box 1 above the roller 303, and nozzles 401 are evenly distributed and fixed through the periphery of the cleaning pipe 4, with the nozzles 401 tilted downward toward the belt 304. Some impurities on belt 304 fall off when passing through roller 303, while some remain attached to belt 304. At this time, cleaning water is output from cleaning pipe 4 and sprayed from nozzle 401 to wash away the ferromagnetic impurities attached to belt 304. A feed hopper 2 is fixed on the inner top surface of the processing box 1; the feed hopper 2 is used for the input of slurry.

[0020] Symmetrically distributed support legs 103 are fixed on both outer side walls of the processing box 1, and a support plate 1031 is fixed between the four support legs 103. The entire processing box 1 is supported by outriggers 103, which raise it a certain distance from the ground, and the structure is reinforced by support plates 1031.

[0021] A support base 1041 is also fixed on the side of the processing box 1, and a reduction motor 104 is fixed on the upper end of the support base 1041. The output shaft of the reduction motor 104 is connected to the end of the magnetic roller 301. A geared motor 104 is installed on the support base 1041. When the geared motor 104 is working, it can drive the magnetic roller 301 to rotate, thereby driving the belt 304 to operate in conjunction with the magnetic roller 302 and the rotating roller 303.

[0022] A feed pipe 201 is fixedly fixed to the top of the feed hopper 2, and the upper end of the feed pipe 201 penetrates the top surface of the processing box 1 and extends out. The bottom surface of the feed hopper 2 is provided with equidistantly distributed material holes 202. The feed pipe 201 is connected to an external slurry conveying device. After passing through the feed hopper 2, the slurry is discharged through the feed hole 202 and introduced into the feed trough 3041 on the belt 304.

[0023] A triangular frustum 105 is fixed on the inner bottom surface of the processing box 1, and openings are provided on the bottom of the processing box 1 on both sides of the triangular frustum 105. A slurry discharge hopper 101 and a magnetic powder discharge hopper 102 are fixed below the two openings respectively. The slurry discharge hopper 101 is located below the magnetic roller 302, and the magnetic powder discharge hopper 102 is located below the rotating roller 303. The triangular platform 105 is designed so that its two inclined surfaces can guide the slurry, cleaning water and other substances dripping from the belt 304, and prevent the cleaning water and slurry from mixing. In this way, the slurry after iron removal will be discharged from the slurry discharge hopper 101, and the ferromagnetic impurities will be discharged from the magnetic powder discharge hopper 102.

[0024] The end of the cleaning pipe 4 is fixed with a water inlet pipe 402. The nozzle 401 faces the inclined surface of the belt 304 between the magnetic roller 1 301 and the rotating roller 303. The bottom of the feed hopper 2 faces the inclined surface of the belt 304 between the magnetic roller 1 301 and the magnetic roller 2 302. External cleaning water is connected through the water inlet pipe 402 and delivered into the cleaning pipe 4. Finally, the water is sprayed out through the nozzle 401. The nozzle 401 is tilted downwards to clean the ferromagnetic impurities on the belt 304, causing the ferromagnetic impurities to flow down and be discharged quickly.

[0025] Magnetic plate 305 contacts the inner surface of belt 304 between magnetic roller 301 and magnetic roller 302, and magnetic plate 306 contacts the inner surface of belt 304 between magnetic roller 302 and roller 303; it can both adsorb ferromagnetic impurities in the slurry and keep them on the surface of belt 304, and provide some support for belt 304 to avoid excessive deformation.

[0026] The specific working principle of this utility model is as follows: First, the feed pipe 201 is connected to an external slurry conveying device. After entering the feed hopper 2, the slurry is discharged through the feed hole 202 and guided into the trough 3041 on the belt 304. At the same time, the reduction motor 104 works to drive the magnetic roller 301 to rotate. Thus, with the cooperation of the magnetic roller 302 and the rotating roller 303, the belt 304 is driven to rotate. The belt 304 rotates in the direction of the magnetic roller 301, the magnetic roller 302, and the rotating roller 303. The slurry slides down the belt 304 between the magnetic roller 301 and the magnetic roller 302 until it enters the slurry discharge hopper. During this process, ferromagnetic impurities in the slurry are adsorbed onto the outer surface of the belt 304 by magnetic plate 305, magnetic roller 302, and magnetic plate 306, leaving only clean slurry to be discharged. When the belt 304 passes the roller 303, because the roller 303 has no magnetic attraction, the ferromagnetic impurities adsorbed on the belt 304 will fall off when passing the roller 303. Some of them will still adhere to the belt 304. At this time, the cleaning pipe 4 outputs cleaning water from the nozzle 401 to wash off the ferromagnetic impurities adhering to the belt 304, completing the uninterrupted cleaning operation and ensuring the continuous operation of the electromagnetic iron removal operation.

[0027] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
