Description

Technical Field

[0001] The invention relates to the technical field of ball mills, in particular to an energy-saving cleaning device for a magnetic ball mill drum structure. Background Art

[0002] A ball mill is a key piece of equipment for pulverizing materials after crushing. This type of mill uses a cylinder filled with a predetermined number of steel balls as the grinding medium. It is widely used in industries such as cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics for dry or wet grinding of various ores and other grindable materials. Suitable for grinding a variety of ores and other materials, ball mills are widely used in industries such as mineral processing, building materials, and chemicals. They can be categorized into two types of grinding methods: dry and wet. According to the different discharge methods, ball mills can be divided into grid type and overflow type. The current ball mills are also divided into conventional ball mills and magnetic ball mills. For magnetic ball mills, it is the first choice for efficiently preparing magnetic particles and nanomaterials and optimizing the magnetic properties of materials. In the process of processing materials, adding grinding aids (such as 0.15kg / t water glass) can improve the grinding efficiency by 5%-10%. The grinding aid particles are still magnetic steel balls. During its use, the material is processed by setting a certain processing time. After the equipment is used to a certain frequency, it needs to be cleaned to prevent the drum structure of the equipment from forming a film inside the long-term processing of magnetic adhesive materials, resulting in reduced crushing efficiency. In order to improve processing efficiency, the existing drum structure is mostly fully enclosed. Therefore, whenever the inside of the drum structure needs to be cleaned, the bolts and related connectors on its surface need to be manually disassembled and the cleaning fluid needs to be injected into its internal surface. Therefore, it is more troublesome and requires large equipment to be transported, which is quite costly. For this reason, we propose an energy-saving cleaning device for the drum structure of a magnetic ball mill. Summary of the Invention

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0025] See also Figure 1-8The application provides a technical scheme: an energy-saving cleaning device for a magnetic ball mill drum structure, which comprises a bottom plate 1, a placing table 2 is fixedly installed on the top of the bottom plate 1, a stabilizing seat 3 is fixedly installed on the top of each placing table 2, a limiting seat 4 is fixedly installed on each stabilizing seat 3, a roller 5 is rotatably connected between the two limiting seats 4, a vertical plate 21 is fixedly connected on the top of each side of the bottom plate 1, a conveying belt 22 is transmissionally connected between opposite sides of the vertical plate 21, an air suction pipe 2101 is connected to one end of the conveying belt 22, the air suction pipe 2101 is rotatably connected with the vertical plate 21 (can be pulled away along the vertical plate 21), springs 24 are sleeved on both ends of the air suction pipe 2101, a connecting sleeve 25 is fixedly connected to one end of each spring 24, an air cylinder 23 is fixedly connected between the connecting sleeve 25 and the vertical plate 21, a plurality of tensioning strips 26 are fixedly connected between the two connecting sleeves 25, a plurality of cleaners 27 are detachably connected to each tensioning strip 26, an air pipe 20 is rotatably connected to one end of the air suction pipe 2101, a fan 32 is fixedly installed on the top of the bottom plate 1, the air pipe 20 is connected with the fan 32, when the device is working, a proper amount of magnetic steel balls is inserted into the roller 5 through manual operation, then the tensioning strips 26 are straightened, the tensioning strips 26 are tightened at the shaft position of the roller 5 through the retraction of the air cylinder 23, and the springs 24 are in a compressed state, when the roller 5 rotates, the steel balls crush and grind the materials, when the device needs to be cleaned, the air cylinders 23 are extended, the springs 24 are reset, the plurality of tensioning strips 26 are in a relaxed state in the roller 5, and when the edges of the tensioning strips 26 contact the inlets at the two ends of the roller 5, the edges of the tensioning strips 26 are stressed, the plurality of tensioning strips 26 gradually form an inverse arch shape, the middle part of the tensioning strips 26 is close to the inner wall of the roller 5, the plurality of cleaners 27 are close to the inner wall of the roller 5, the impurities on the inner wall of the roller 5 are adsorbed by the cleaners 27, and the cleaners 27 are provided in plurality, which can clean the inner wall of the roller 5 and improve the processing efficiency.

[0026] Further, the plurality of tensioning strips 26 are close to the surface of the air suction pipe 2101 and surround the air suction pipe 2101 to form a rectangle, the surface of the air suction pipe 2101 is provided with a plurality of micro holes (not shown in the figure and can be drilled during production), when the device is in the processing or cleaning state, the fan 32 should be immediately started, after the fan 32 is started, the dust on the inner wall of the roller 5 can be sucked through the air suction pipe 2101 and introduced to the outside through the air pipe 20, so that the dust is prevented from being dry and solidified in the roller 5 after the device is stopped, and the burden of the cleaners 27 is reduced.

[0027] Furthermore, the cleaner 27 includes a fixed seat 28 movably connected to the tensioning strip 26, a positioning ball 29 is fixedly installed on one side of the fixed seat 28, the positioning ball 29 is movably connected to a movable plug 30, and a magnetic block 31 is fixedly installed on the movable plug 30. When the two ends of the tensioning strip 26 are squeezed toward the middle thereof, the tensioning strip 26 is in a reverse bow state, so that the magnetic block 31 on the tensioning strip 26 can absorb the magnetic deposits, and the magnetic block 31 is fixedly connected to the movable plug 30 and is in a swinging state on the positioning ball 29, thereby increasing the cleaning range of the magnetic block 31 and allowing the magnetic block 31 to clean the surface area, as shown in the attached figure. Figure 6 As shown, the magnetic block 31 has a large number of hollow structures, which can properly pick up relatively sticky powder materials, improve the adaptability of the magnetic block 31, and expand the functional use of the device.

[0028] Furthermore, transmission plates 8 are fixedly installed on both sides of the top of the placement table 2 near each stable seat 3, and a rotor 801 is fixedly installed on the transmission plate 8. A rolling ring 6 is rotatably connected between the two rotors 801, a magnetic piece 9 is fixedly installed between the two rolling rings 6, and a second gear 12 is fixedly installed in the middle of the magnetic piece 9. A first motor 10 and a second motor 13 are fixedly installed on the top of the placement table 2. The output shafts of the first motor 10 and the second motor 13 are both sleeved with a driving gear 11, one of the driving gears 11 is meshed with the second gear 12, and the other driving gear 11 is meshed with the first gear 7. The output shaft of the second motor 13 is extended to the vertical plate 21, and the end of the conveyor belt 22 is sleeved with the output shaft of the second motor 13; the magnetism of the magnetic block 31 is relative to the magnetism of the magnetic piece 9. On the contrary, the magnetic sheet 9 is attracted to the magnetic block 31 through the roller 5, and the magnetism of the magnetic block 31 is the same as that of the steel ball used in the roller 5, and they repel each other. When the device is in use, the second motor 13 is turned on to rotate. The rotation of the second motor 13 causes the other driving gear 11 to drive the first gear 7, thereby rotating the roller 5. At the same time, the second motor 13 rotates the conveyor belt 22 during the rotation process, and then the conveyor belt 22 drives the air suction pipe 2101 to rotate axially, so that the rotation direction of the air suction pipe 2101 is the same as that of the roller 5. Due to the difference in gear ratio between the driving gear 11 and the first gear 7, the rotation speed of the air suction pipe 2101 is slightly faster than that of the roller 5, which is conducive to the magnetic block 31 to quickly clean the inside of the roller 5.

[0029] When the device needs to be cleaned, the first motor 10 is turned on, and the first motor 10 drives the second gear 12 to rotate in the opposite direction relative to the drum 5 during the rotation, so that the magnetic force of the magnetic sheet 9 passes through the drum 5, allowing the magnetic sheet 9 to guide the magnetic steel balls, thereby improving the activity of the magnetic steel balls inside the drum 5 and reducing the processing time. At the same time, the device rotates synchronously with the drum 5 through the air suction pipe 2101, which saves energy and reduces processing costs.

[0030] The inside of the drum 5 is fixedly installed with raised hills 501 in a circular shape and at equal intervals. The outer surface of the drum 5 is fixedly installed with multiple external magnets 14. The raised hills 501 can effectively make the magnetic block 31 and the tensioning strip 26 quickly contact the raised hills 501, and the raised hills 501 enhance the striking effect of the magnetic steel balls. The magnetic properties of the magnetic sheet 9 and the external magnet 14 are opposite. When necessary, the drum 5 can form a braking relationship with the magnetic sheet 9 through the external magnet 14. When the drum 5 is out of control, the magnetic sheet 9 is stationary, which can effectively put the drum 5 into a braking process.

[0031] Furthermore, one end of one of the limit seats 4 is rotatably connected to a drum 15, the end of the drum 15 is inserted into the drum 5 and communicates with the drum 5, a thread is provided on the outside of the drum 15, and the outer ring of the drum 15 is connected to a movable plate 16 through a thread, and one end of the drum 5 is slidably connected to a plurality of alignment rods 18, and a patch 17 is fixedly installed at one end of the plurality of alignment rods 18, and a baffle 19 is fixedly installed at the other end of each alignment rod 18. When the equipment needs to be cleaned, the drum 15 can be rotated manually on the outside of the drum 15, and the fixed seat 28 and the tensioning strip 26 are fitted together by interference, and are connected. The size of the socket 25 matches the size of the openings at both ends of the drum 5; when the drum 15 rotates, the movable plate 16 moves on the thread, so that the patch 17 moves toward the end of the drum 5, and the alignment rod 18 pushes the baffle 19 to move deep into the inside of the drum 5, so that after the tensioning strip 26 is unfolded, the baffle 19 and the alignment rod 18 structure lock the position of the tensioning strip 26, increase the expansion range of the tensioning strip 26, reduce the dead angle range of the end of the tensioning strip 26 and the inside of the drum 5, and maintain the expanded state of both ends of the tensioning strip 26, thereby improving the utilization rate of the tensioning strip 26.

[0032] The axis of the air suction pipe 2101 coincides with the axis of the roller 5. The roller 5 is made of austenitic stainless steel. Austenitic stainless steel has weak magnetism and can well assist the magnetic force of the magnetic sheet 9 to pass through, thereby improving the magnetic penetration of the magnetic sheet 9.
