DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0027] As Figure 1 ,Figure 2 As shown in the figure, a device for removing iron from the original slurry in ceramic production disclosed in a specific embodiment of the present invention includes a conveyor belt 100, a magnetic attraction structure 200, a cloth trough 300, and an aggregate trough 400; the conveyor belt 100 is inclined and installed on a frame 500, the magnetic attraction structure 200 is installed between the two belt surfaces of the conveyor belt 100, and a magnetic attraction area is formed at the upper belt surface of the conveyor belt. The magnetic attraction area extends along the length direction of the conveyor belt to one side close to the center of the bending parts at both ends of the conveyor belt; the cloth trough 300 is arranged above the conveyor belt 100, and the feeding hole of the cloth trough falls into the magnetic attraction area; the aggregate trough 400 is arranged below the higher end of the inclined conveyor belt 100 for collecting iron filings that fall after leaving the magnetic attraction area.

[0028] For the above device for removing iron from the original slurry in ceramic production, the conveyor belt is used as a component for transporting the slurry, and the magnetic attraction structure is used to separate the magnetic iron filings. Then, the conveyor belt transfers the separated iron filings to the aggregate trough. Using the conveyor belt as a component for feeding, separating, and transferring iron filings, the treatment method is simple, the operation efficiency is high, and effective iron removal and separation actions can be carried out; moreover, the overall structure is simple, conventional components are used, the cost is low, and it is convenient for production and application.

[0029] Further, as Figure 3 shown, the magnetic attraction structure 200 includes a support plate 210. The support plate 210 is installed on the frame 500 and crosses the middle of the conveyor belt. The length of the support plate is less than the minimum distance between the support rollers at both ends of the conveyor belt; a backing plate 220 is fixedly arranged on the top surface of the support plate 210, and the inner wall of the upper belt surface of the conveyor belt 100 abuts against and slides on the top surface of the backing plate 220; a plurality of grooves 230 arranged in an array along the width direction of the conveyor belt 100 are provided on the backing plate 220. The grooves extend along the conveying direction of the conveyor belt. Magnet bars 240 are placed at the grooves 230. Using the grooves as parts for accommodating and placing the magnet bars can effectively prevent the magnet bars from running off track and keep them in the corresponding working positions; moreover, this method does not require too many limitations on the magnet bars themselves, which is convenient for disassembly and assembly; the top surface of the magnet bar 240 is 0.5 mm - 2 mm lower than the top surface of the backing plate 220. This limitation can prevent the magnet bar from contacting the belt surface of the conveyor belt, further prevent the magnet bar from running off track, reduce the wear of the magnet bar, and extend its service life; moreover, it can weaken the magnetic attraction force to facilitate the subsequent separation of iron filings.

[0030] Further, the support plate and the frame can be connected through a slide rail assembly, so that the support plate can be pulled from one side of the frame to the outside for disassembly, replacement, and installation of the internal magnet bars, which is convenient for actual operation; it should be noted that threaded holes are provided at the ends of the frame corresponding to the slide rail assembly for installing limit bolts. After the magnetic attraction structure is installed in place, it is limited by the limit bolts to keep the magnetic attraction structure in the required position and provide the corresponding magnetic attraction and iron removal function;

[0031] Furthermore, the pad is one of wear-resistant nylon plate, PP plate or ABS plastic plate, which provides sufficient supporting strength and wear resistance, so that a certain spacing effect is maintained between the magnet bar and the conveyor belt surface, which can not only meet the required magnetic attraction effect, but also facilitate the subsequent iron filings to be smoothly separated from the magnetic attraction area.

[0032] Furthermore, if Figure 1 As shown, a plurality of discharge holes 310 are provided at the bottom of the material distribution trough 300, and the plurality of discharge holes 310 are arranged in a plurality of groups corresponding to the magnet strips 240, and one magnet strip corresponds to at least two discharge holes; it is defined that the slurry falls from the position corresponding to the magnet strip, so that the slurry is in full contact with the magnet strip, and effective magnetic separation is performed;

[0033] Furthermore, the distribution trough spans across the top of the conveyor belt and is mounted on the frame. The inner ends of the distribution trough are provided with guide surfaces that are inclined downward toward the center of the distribution trough, forming a trough bottom that narrows downward, and the discharge holes all fall at the narrowed position; this structural design forms a larger flare at the top to accommodate more slurry, and the narrowing at the bottom can have a guide effect, so that the slurry converges in the direction of the discharge hole, reducing retention and accumulation.

[0034] Furthermore, if Figure 1 , Figure 2 As shown, a blowing structure 600 and a spraying structure 700 are provided on one side of the distribution trough 300 close to the collecting trough 400; the blowing structure is used to spray the liquid moving upward along the conveyor belt to separate the slurry from the iron filings; the spraying structure is used to spray clean water to clean the conveyor belt below the path and clear the slurry except the iron filings; this structural design can spray the slurry moving upward along the conveyor belt, prevent the slurry from moving upward along the conveyor belt, and reduce the diffusion of the slurry to the higher side of the conveyor belt; the spraying structure can flush the conveyor belt and iron filings below the path by spraying clean water, further reducing the mud entrained in the debris.

[0035] Furthermore, it includes at least two spraying structures, and the spraying structure is arranged between the spraying structures. The first spraying structure is mainly used for spraying mud to prevent the mud from spreading; the second spraying structure is used for spraying the flushed conveyor belt and iron filings to reduce the liquid falling into the aggregate trough, which is convenient for subsequent cleaning.

[0036] Furthermore, if Figure 2As shown, the injection structure 600 includes an air delivery pipe 610 and a nozzle 620 that are connected to each other. First mounting plates are fixedly provided at both ends of the nozzle. The first mounting plates are mounted on the frame. The nozzle 620 is located above the conveyor belt 100, and the air outlet of the nozzle is inclined towards one side of the cloth trough. A first throttle valve 630 for regulating the air flow rate is installed on the air delivery pipe 610. The input end of the air delivery pipe is connected to an external air source. An air curtain with a certain pressure is formed by providing air flow to the injection structure through the external air source to effectively inject the slurry or muddy water adhering to the conveyor belt, achieving the required cleaning effect.

[0037] Further, as Figure 4 shown, the spraying structure 700 includes a water delivery pipe 710 and a spray pipe 720 that are connected to each other. Second mounting plates are fixedly provided at both ends of the spray pipe. The second mounting plates are mounted on the frame. The spray pipe 720 is located above the conveyor belt 100.

[0038] A second throttle valve 730 for regulating the water flow rate is installed on the water delivery pipe 710. The input end of the water delivery pipe is connected to an external water source.

[0039] Drain holes are provided at the bottom of the spray pipe. A liquid trough 750 is fixedly provided on the outer side of the bottom of the spray pipe 720. The liquid trough extends along the length direction of the spray pipe. A clamping opening 740 is formed between the two sides of the liquid trough 750 and the outer wall of the spray pipe 720. The clear water flowing out from the drain holes enters the liquid trough and then overflows from both sides of the clamping opening to form a water curtain. A relatively comprehensive water curtain is formed by the overflow method, which can effectively wash and clean the conveyor belt and iron filings passing below, reducing the mud from falling into the aggregate trough.

[0040] It should be noted that since the conveyor belt is inclined, the heights on both sides of the liquid trough need to be adapted to the inclination angle so that the clamping openings on both sides are at the same height position to form a double-layer water curtain effect. Further, preferably two spraying structures are provided. The water flow of the spraying structure closer to the cloth trough side is larger to wash more slurry. The water flow at the rear is smaller, which can better clean the remaining part, weaken the impact on the iron filings, and prevent the iron filings from breaking away and flowing back.

[0041] Further, as Figure 1As shown in the figure, a cleaning structure 800 is provided outside the higher inclined end of the conveyor belt 100; the cleaning structure 800 includes a first brush roll 810 and a second brush roll 820 rotatably mounted on the frame through bearings. The first brush roll 810 is correspondingly arranged outside the corner of the bending part of the conveyor belt 100, and the second brush roll 820 is correspondingly arranged below the corner of the bending part of the conveyor belt 100; the first brush roll and the second brush roll are in transmission connection with the support roll of the conveyor belt, and the bristles of the first brush roll and the second brush roll abut against the outer wall of the conveyor belt and slide; the provided cleaning structure can clean the discharging end of the conveyor belt by means of active cleaning, accelerate and ensure the dropping of the adhered iron filings, improve the efficiency and reduce the waste; moreover, the cleaning structure is connected to the driving structure of the conveyor belt, without the need to design additional electrical components, which can reduce the cost.

[0042] Further, the roller shaft of the first brush roll and the roller shaft of the support roll are in meshing transmission through gears; the roller shaft of the second brush roll and the roller shaft of the support roll are in transmission connection through a sprocket chain assembly; with this cooperation, the first brush roll rolls and brushes from bottom to top, while the second brush roll brushes from bottom to top, which can ensure comprehensive cleaning and prevent the dropping and waste of iron filings;

[0043] Further, a first gear is fixedly provided on one end roller shaft of the support roll, and a first sprocket is fixedly provided on the other end roller shaft; a second gear is correspondingly fixedly provided on the roller shaft of the first brush roll, and the second gear is in meshing transmission with the first gear; a second sprocket is correspondingly provided on the roller shaft of the second brush roll, and the second sprocket and the first sprocket are in transmission connection through a chain; one end roller shaft end of the support roll is connected to the output shaft of the motor through a gearbox, providing sufficient torque to drive the conveyor belt, the first brush roll and the second brush roll to rotate, so as to meet the conveying of materials and the cleaning of iron filings at the end;

[0044] Further, skirt edges are provided on both sides of the conveyor belt, and the bristles at the positions corresponding to the skirt edges at both ends of the first brush roll and the second brush roll are sparser than those at other parts, which can clean the skirt edge parts and prevent affecting the normal movement of the conveyor belt.

[0045] The present invention is described by way of preferred embodiments. Those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present invention.
