Description

Technical Field

[0001] The present application relates to the field of ceramic equipment, and in particular to a wet electromagnetic iron remover. Background Art

[0002] ‌Electromagnetic iron remover‌ is a device that uses the principle of electromagnetic induction to remove ferromagnetic impurities from materials. Its working principle is based on the physical principles of electromagnetic induction and magnetic field attraction. When the electromagnetic coil of the electromagnetic iron remover is powered on, the current passes through the coil to generate a magnetic field, which can attract ferromagnetic substances and separate them from the material.

[0003] The electromagnetic iron removers currently used include wet iron removers and dry iron removers. The main working principle of the wet iron remover is to use water as a carrier of the material and drive the material through the magnetic medium. In the process of the material passing through the magnetic medium, the iron powder in the material is adsorbed by the magnetic medium, thereby achieving full removal of the iron powder in the material.

[0004] At present, the magnetic conductive medium in the wet electromagnetic iron remover is mostly an iron mesh plate. Each mesh plate is evenly distributed with through holes of the same size for the objects to pass through. During use, multiple iron mesh plates are stacked on the outside of the same column, so that the magnetic conductive mesh plate can adsorb the iron powder in the material while the material passes through the mesh plate.

[0005] When using the above-mentioned magnetic conductive medium, different workers place the screens in different ways during the stacking process, which leads to differences in the distribution of holes between the adjacent screens on the upper and lower sides, resulting in differences in the iron removal efficiency of the same batch of electromagnetic iron removers, affecting the overall quality standards of the equipment. Summary of the invention

After that, when the material passes through the magnetic plate, the iron powder in the material is attracted by the magnetic plate, thereby realizing the process of removing the iron powder mixed in the material. In addition, since the filter holes on the two adjacent magnetic plates are staggered, it can reduce the phenomenon that the position of the magnetic plate is difficult to control when the staff places the magnetic plate, thereby affecting the iron removal efficiency of the iron powder in the material.

The driven gear drives the reciprocating screw to move back and forth during the rotation process. The reciprocating screw squeezes out the condensed water on the lower side through the extrusion gap during the downward movement, thereby realizing the compression process of the condensed water.

[0021] Optionally, two air-cooling enclosures are provided on the lower side of the compression plate, which are arranged opposite to each other up and down.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0038] The embodiment of the present application discloses a wet electromagnetic iron remover.

[0039] Example 1 Reference Figure 1 , Figure 2 and Figure 3 A wet electromagnetic iron remover includes a frame 1, and a body 2 is connected to the upper side of the frame 1. The body 2 includes a vertically arranged filter cartridge 21, and the filter cartridge 21 is cylindrical. A coil casing 22 is sleeved on the outside of the filter cartridge 21, and an electromagnetic coil 23 is arranged inside the coil casing 22. The electromagnetic coil 23 is evenly distributed around the filter cartridge 21 in a ring shape. The lower side of the filter cartridge 21 is connected to a lower water inlet pipe 211, a feed pipe 212 and a lower iron discharge pipe 213. The upper end of the filter cartridge 21 is connected to an upper water inlet pipe 214, a slurry outlet pipe 215 and an upper iron discharge pipe 216. The lower water inlet pipe 211 and the upper water inlet pipe 214 are connected to the same water pump 3.

[0040] A vertical column 4 is provided inside the filter cartridge 21, and the center line of the column 4 coincides with the center line of the filter cartridge 21. A plurality of media components 5 are sleeved outside the column 4.

[0041] Each medium component 5 includes a plurality of magnetic conductive plates 51. In the present embodiment, the number of magnetic conductive plates 51 is three, and the three magnetic conductive plates 51 are evenly and spaced apart in the vertical direction, and the interval between two adjacent magnetic conductive plates 51 is not greater than 5 mm. A plurality of filter holes 511 are provided on each magnetic conductive plate 51, and the filter holes 511 provided on the upper and lower adjacent magnetic conductive plates 51 are staggered. Each magnetic conductive plate 51 is sleeved onto the outside of the column 4 and is slidably engaged with the column 4 along the length direction of the column. In the present embodiment, the engagement method adopts the engagement form of a slider slot. The column 4 is provided with limit blocks 41 for limiting the relative position of the magnetic conductive plate 51 and the column 4 on both upper and lower sides of the plurality of magnetic conductive plates 51.

[0042] In practical use, the electromagnetic coil 23 is energized, and then the material is guided into the filter cartridge 21 through the feed pipe 212 and at the same time, water is guided from the lower water inlet pipe 211 to the inside of the filter cartridge 21 through the water pump 3. Then, as the material passes through the medium component 5, the iron powder in the material is adsorbed by the medium component 5, and the remaining material is discharged from the slurry discharge pipe 215, thereby realizing the iron removal process of the material.

[0043] By limiting the relative position of the filter holes 511 between two adjacent magnetic conductive plates 51 , the iron removal efficiency of different electromagnetic iron removers in the same batch can be made more uniform.

[0044] The dielectric component 5 also includes a magnetic conductive ring 52, which is simultaneously sleeved on the outside of the three magnetic conductive plates 51 in the same group. The outer wall of each magnetic conductive plate 51 is fixedly connected with a plurality of support rods 512, and each support rod 512 is plugged into the inner side wall of the adjacent magnetic conductive ring 52 and fixedly connected with a support block 513. A support spring 514 is fixedly connected between the upper and lower adjacent support blocks 513, and the support spring 514 is set as a pressure spring. And each support rod 512 is slidably connected with the inner wall of the plugged magnetic conductive ring 52 in the vertical direction.

[0045] The outer wall of each magnetic ring 52 abuts against the inner wall of the adjacent filter cartridge 21 , and the bottom of the inner wall of the filter cartridge 21 is configured to be open from bottom to top, and the inner diameter of the uppermost end of the open inner wall is consistent with the inner diameter of the magnetic ring 52 .

[0046] The upper end of the filter cartridge 21 is also connected to a high-pressure air pump 6 , which is used to inflate air into the filter cartridge 21 .

[0047] When it is necessary to clean the iron powder adhered to the magnetic plate 51, firstly, the electromagnetic coil 23 is powered off, and then two cleaning methods can be selected. One is to introduce clean water from the lower water inlet pipe 211 from bottom to top into the filter cartridge 21 through the water pump 3, and then the clean water is used to clean the filter plate, so that the iron powder adsorbed in the filter cartridge 21 is discharged from the upper iron pipe 216 into the filter cartridge 21. When the cleaning is not sufficient, the second method is adopted, that is, to guide clean water from the upper water inlet pipe 214 from top to bottom into the filter cartridge 21 through the water pump 3. At the same time, the water inside the filter cartridge 21 is pressurized by the high-pressure air pump 6. Thereby, the pressurized water can drive the support blocks 513 connected to the multiple magnetic plates 51 to squeeze the support springs 514, so that the magnetic plates 51 move up and down slightly. Thereby, the adhered iron powder is shaken off, and the iron powder on the magnetic plate 51 is fully cleaned. Afterwards, the clean water mixed with iron powder is discharged from the lower iron pipe 213.

[0048] A plurality of protrusions 515 are fixedly connected to the upper and lower side walls of each magnetic conductive plate 51 located in the middle position of the magnetic conductive ring 52, and each protrusion 515 is arranged corresponding to one of the filter holes 511 on the adjacent magnetic conductive plate 51. A plurality of similar protrusions 515 are fixedly connected to the side walls of the magnetic conductive plate 51 located near the middle position of each magnetic conductive plate 51 located on the upper and lower sides of the magnetic conductive ring 52, and each protrusion 515 is arranged corresponding to one of the filter holes 511 on the adjacent magnetic conductive plate 51. Each protrusion 515 can be inserted into the corresponding filter hole 511 during the movement of the connected magnetic conductive plate 51 and is spaced from the inner wall of the filter hole 511.

[0049] A plurality of contact rods 516 are fixedly connected to the inner wall of each filter hole 511 near the corresponding protrusion 515, and each contact rod 516 can abut against an adjacent protrusion 515. The contact rod 516 is made of magnetic conductive material, and in this embodiment, the contact rod 516 is made of iron.

[0050] In actual use, the provision of the protrusion 515 further limits the moving path of the material between the two magnetic conductive plates 51, so that the iron powder in the material can be in more sufficient contact with the magnetic conductive plates 51, so that the iron remover can more fully remove the iron powder in the material. By providing the touch rod 516, the touch rod 516 can capture the iron powder mixed in the material when the material passes through the filter hole 511, thereby improving the iron removal quality of the electromagnetic iron remover. And in the process of cleaning the magnetic conductive plate 51, as the magnetic conductive plate 51 moves, the touch rod 516 abuts against the protrusion 515, thereby achieving a small amplitude vibration of the magnetic conductive plate 51, and then can speed up the falling process of the iron powder on the magnetic conductive plate 51.

[0051] The implementation principle of Example 1 is: the electromagnetic coil 23 is energized, and the slurry-water mixture is introduced into the filter cylinder 21 through the lower water inlet pipe 211 and the feed pipe 212. After that, the iron powder in the slurry contacts the magnetic plate 51, and the magnetic plate 51 adsorbs the iron powder in the slurry, thereby realizing the removal operation of the iron powder in the material.

[0052] When it is necessary to clean the iron powder inside the filter cartridge 21, the electromagnetic coil 23 is powered off, and then clean water is guided into the filter cartridge 21 from bottom to top or from top to bottom, thereby flushing the iron powder on the magnetic plate 51. After that, the water containing the iron powder is discharged from the upper iron pipe 216 or the lower iron pipe 213, thereby cleaning the iron powder adhered to the magnetic plate 51.

[0053] Example 2 Reference Figure 4 The embodiment of the present application is different from the embodiment 1 in that a accordion plate 517 for blocking the slot is provided at the slot provided on the inner wall of the magnetic ring 52 for the support rod 512 to slide.

[0054] The implementation principle of Example 2 is: by providing the accordion plate 517, the material or iron powder is reduced from entering the magnetic conductive ring 52, thereby affecting the movement of the magnetic conductive plate 51.

[0055] Example 3 Reference Figure 5 , Figure 6 , Figure 7 and Figure 8The embodiment of the present application is different from embodiment 1 and embodiment 2 in that a condenser 7 is coiled inside the coil casing 22, and the tube walls at the water inlet end 71 and the water outlet end 72 of the condenser 7 both penetrate the coil casing 22 and are fixedly connected to the side wall of the coil casing 22.

[0056] The water inlet end 71 and the water outlet end 72 of the condenser 7 are connected to a condensation mechanism 8 , and the condensation mechanism 8 is used to cool down the heated water inside the condenser 7 .

[0057] By providing the condensation mechanism 8, the condensed water heated inside the condensation tube 7 can be cooled down, thereby reducing the use of external cooling water and reducing the waste of water resources.

[0058] The condensation mechanism 8 includes a condensation box 81, the pipe wall at the water inlet end 71 of the condensation pipe 7 penetrates the lower side of the side wall of the condensation box 81 and is fixedly connected to the side wall of the condensation box 81, and a pump body 73 is installed near the water inlet end 71 of the condensation pipe 7. The pipe wall at the water outlet end 72 of the condensation pipe 7 penetrates the upper side of the side wall of the condensation box 81 and is fixedly connected to the side wall of the condensation box 81.

[0059] The condenser box 81 is provided with a compression assembly 82 and an air cooling assembly 83 from top to bottom. The compression assembly 82 is used to compress the water inside the condenser box 81, thereby increasing the distance between water molecules. The air cooling assembly 83 can exchange heat between the compressed water and the outside air, thereby reducing the temperature of the water inside the condenser box 81.

[0060] In actual use, the condenser 7 guides the water with increased temperature inside the coil casing 22 to the inside of the condensation box 81, and then the water with higher temperature entering the condensation box 81 is compressed by the compression component 82. The compressed water enters the air cooling component 83 for cooling, and the cooled water returns to the inside of the coil casing 22 again, thereby realizing the circulation process of condensed water.

[0061] The compression assembly 82 includes an extrusion plate 821 located on the upper side of the water outlet end 72 of the condensing tube 7. The extrusion plate 821 is arranged horizontally and slides against the inner wall of the condensing box 81 in the vertical direction. A reciprocating screw 822 is fixedly connected to the upper side of the extrusion plate 821. The end of the reciprocating screw 822 away from the extrusion plate 821 penetrates the top wall of the condensing box 81 and slides with the top wall of the condensing box 81 in the vertical direction. The part of the reciprocating screw 822 that penetrates the top wall of the condensing box 81 is threadedly sleeved with a driven gear 8221. A driving gear 8222 is meshed with one side of the driving gear 8222. The driving gear 8222 is fixedly connected to a motor 84 for driving the driving gear 8222 to rotate. A baffle 8211 is fixedly connected to the end of the lower side of the extrusion plate 821 close to the condensing tube 7. The baffle 8211 can shield the water guided to the inside of the condensing box 81 by the condensing tube 7 during the downward movement of the extrusion plate 821.

[0062] Two compression plates 823 are arranged opposite to each other in the part below the water outlet end 72 of the condensing pipe 7 in the condensing box 81. The two compression plates 823 are arranged downwardly and inclined toward each other. A small compression gap 8231 is left at the position where the two compression plates 823 are close to each other. The size of the compression gap 8231 is set to 5-8 mm. In this embodiment, the size of the compression gap 8231 is set to 6 mm.

[0063] When it is necessary to compress the water inside the condensation tank 81, the motor is turned on, and the motor drives the driving gear 8222 to rotate. The driving gear 8222 drives the connected driven gear 8221 to rotate during the rotation process, and the driven gear 8221 drives the connected reciprocating screw 822 and the connected extrusion plate 821 to reciprocate during the rotation process. When the extrusion plate 821 moves downward, the water on the lower side of the extrusion plate 821 passes through the compression slit 8231, thereby achieving the compression operation of the water inside the condensation tank 81.

[0064] A pressure relief groove 811 is provided outwardly on the upper side of the condensation box 81 away from the side wall connected to the condensation tube 7. When the extrusion plate 821 moves to the pressure relief groove 811, the condensation box 81 cavity on the upper and lower sides of the extrusion plate 821 can be connected. The condensation box 81 is provided with a plurality of pressure relief holes 812. In this embodiment, the number of pressure relief holes 812 is 2, and the two pressure relief holes 812 are arranged at intervals. Two connecting rods 824 are fixedly connected to the upper side wall of the extrusion plate 821, and the two connecting rods 824 are arranged in a one-to-one correspondence with the two pressure relief holes 812. Each connecting rod 824 is plugged into the corresponding pressure relief hole 812 and is arranged at intervals from the hole wall of the pressure relief hole 812. One end of each connecting rod 824 away from the extrusion plate 821 is fixedly connected to a pressing plate 825, and a support plate 826 is slidably sleeved on the lower side of each pressing plate 825. A compression spring 827 is fixedly connected between each support plate 826 and the adjacent pressure plate 825, and the compression spring 827 is wound around the outside of the connecting rod 824. Each support plate 826 can be driven by the compression spring 827 to abut against the top wall of the condenser tube 7 and block the pressure relief hole 812.

[0065] When the pressure inside the condensation box 81 is relatively high due to the large amount of steam inside the condensation box 81, the extrusion plate 821 is moved to the pressure relief groove 811 by a motor, and then the gas inside the condensation box 81 moves to the upper side of the extrusion plate 821 through the pressure relief groove 811, and then the steam pushes the abutment plate 826 to pass through the pressure relief hole 812, thereby realizing the pressure relief process inside the condensation box 81.

[0066] The air cooling assembly 83 includes two air cooling panels 831 located at the lower side of the compression plate 823. The two air cooling panels 831 are both arranged in a V shape and their openings are arranged opposite to each other up and down. The side wall of each air cooling panel 831 is fixedly connected to the inner wall of the adjacent condensation box 81, and a closed cavity is formed between the two air cooling panels 831 and the inner wall of the adjacent condensation box 81, and the two ends of the cavity are connected to the outside.

[0067] A plurality of air cooling pipes 832 are provided between the upper and lower air cooling panels 831. Each air cooling pipe 832 is vertically arranged, and the upper end of each air cooling pipe 832 penetrates the upper air cooling panel 831 and is fixedly connected to the upper air cooling panel 831. The lower end of each air cooling pipe 832 penetrates the lower air cooling panel 831 and is fixedly connected to the lower air cooling panel 831.

[0068] An air-cooling fan 833 is also provided between the upper and lower air-cooling panels 831, and the air inlet end and the air blowing end of the air-cooling fan 833 are both arranged to face the outside. A connecting shaft 834 is fixedly connected to one side of the air-cooling fan 833, and a follower gear 835 is fixedly connected to the end of the connecting shaft 834 away from the air-cooling fan 833, and a driving rack 836 is meshed with one side of the follower gear 835, and the upper end of the driving rack 836 is fixedly connected to the reciprocating screw 822 and can move up and down under the drive of the reciprocating screw 822.

[0069] When the motor drives the compression plate 823 to move up and down to compress the water inside the condenser box 81, the reciprocating screw 822 drives the driving rack 836 to move up and down, and the reciprocating screw 822 drives the follower gear 835 to rotate during the movement, and the follower gear 835 drives the connecting shaft 834 and the air-cooling fan 833 to rotate during the rotation. The air-cooling fan 833 cools the air-cooling pipe 832 and the upper and lower air-cooling panels 831 during the rotation. Therefore, the water with a higher temperature can exchange heat with the air-cooling pipe 832 and the air-cooling panels 831 during the contact with the air-cooling pipe 832 and the air-cooling panels 831, thereby reducing the temperature of the cooling water inside the condenser box 81.

[0070] Two rows of piston tubes 85 are provided below the air-cooled enclosure 831 on the lower side, and the two rows of piston tubes 85 are arranged at intervals and staggered up and down. Each piston tube 85 is arranged horizontally. The end of each piston tube 85 passes through the adjacent side wall of the condensation box 81 and is spaced from the side wall of the condensation box 81 where it passes through. The interior of each piston tube 85 is connected to the outside of the condensation box 81. A piston sleeve 851 is connected between the end of each piston tube 85 and the outer wall of the adjacent condensation box 81, and each piston sleeve 851 can block the gap between the end of the adjacent piston tube 85 and the side wall of the adjacent condensation box 81. Each piston sleeve 851 is set to a flexible rubber material.

[0071] The piston tubes 85 are fixedly connected to the same connecting frame 852 at the same end, and a driving screw 853 is fixedly connected to one side of the connecting frame 852. The driving screw 853 is externally threaded with a connecting gear 854. A vertically arranged connecting rack 855 is meshed on one side of the connecting gear 854, and the upper end of the connecting rack 855 is fixedly connected to the adjacent driving rack 836.

[0072] A plurality of piston fans 856 are installed inside each piston tube 85 .

[0073] When the motor drives the reciprocating screw 822 to move up and down, the reciprocating screw 822 drives the driving rack 836 and the connecting rack 855 to move up and down. The connecting rack 855 drives the connected connecting gear 854 to rotate during the up and down movement. The connecting gear 854 drives the driving screw 853 to move forward and backward during the rotation process, and the driving screw 853 drives the connected multiple piston tubes 85 to move during the movement process.

[0074] During the movement of each piston tube 85, the air inside can be exchanged with the outside air, so that the piston tube 85 can be cooled by the outside air. In addition, by providing the piston sleeve, when the extrusion plate 821 is located at the lower side of the pressure relief groove 811 and the drain pipe is shielded by the baffle 8211, the process of condensed water passing through the compression gap 8231 can be accelerated, thereby improving the cooling efficiency of the cooling water inside the condensation box 81.

[0075] A cooling water pipe 813 is penetrated and fixedly connected to a side wall of the bottom of the condenser box 81 away from the condenser tube 7, and a water inlet valve 8131 is installed on the cooling water pipe 813. A water baffle 814 is provided at the bottom of the condenser box 81 to separate the water pipe, the water inlet end 71 of the condenser tube 7 and the piston tube 85. An opening is provided in the middle of the water baffle 814, and a rotating door 8141 is rotatably connected to the opening to separate the cooling water pipe 813 and the opening.

[0076] By providing a cooling water pipe 813, it is possible to replenish the condensed water that is lacking inside the condenser 7. By providing a rotating door 8141, in the process of replenishing condensed water into the condenser 7 through the cooling water pipe 813, the water inside the cooling water pipe 813 can push the rotating door 8141 to cover the opening of the water baffle 814, thereby reducing the flow of cooling water inside the condenser box 81 to the water inlet end 71 of the condenser 7 during the water adding process.

[0077] The implementation principle of Example 3 is as follows: when the temperature of the condensed water inside the coil casing 22 rises, the water inside the condenser tube 7 is guided to the inside of the condenser box 81, and then the condenser box 81 is cooled by the extrusion plate 821 in cooperation with the air cooling fan 833 and the piston tube 85, thereby realizing the cooling process of the cooling water inside the condenser box 81.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
