Description

Technical Field

[0001] This utility model relates to the field of cobalt blue pigment processing technology, and in particular to a cobalt blue pigment grinding machine. Background Technology

[0002] A grinding mill is a specialized device for processing and grinding cobalt blue pigment. Cobalt blue, also known as cobalt aluminum blue, is an inorganic pigment composed of cobalt and aluminum. The main function of a grinding mill is to crush the raw material into smaller particles to ensure the uniformity and dispersibility of the pigment, thereby improving its performance. During the grinding process of cobalt blue pigment, the machine uses mechanical force to further refine the pigment particles, thereby improving its color saturation and stability.

[0003] During the grinding and processing of cobalt blue pigment, the pigment container containing the pigment is placed on one side of a lifting base. Then, the hydraulic rod inside the lifting base is activated to move the grinder downwards to a certain position, which in turn moves the motor, the fixing frame, and the grinding container downwards, inserting one end of the grinding container and the fixing frame into the pigment container. Then, the motor on one side is activated, driving the pin to rotate, which in turn drives the impeller and the dispersion disc to rotate at the bottom outlet of the inner wall of the grinding container. The rotation of the impeller draws the cobalt blue pigment from the pigment container into the grinding container through the inlet. As the pin drives the impeller to rotate, it also drives the zirconium beads placed in the grinding container to move at high speed. The beads collide with each other, generating extrusion, shearing, and impact forces, breaking up the agglomeration of the pigment particles and refining the particles, achieving the grinding effect. Then, the dispersion disc rotates at the bottom outlet of the grinding container, generating negative pressure to suck the material out and return it to the pigment container. During the grinding process, uneven or insufficient grinding may occur. When finer pigment particles are needed, during the process of the negative pressure formed by the dispersion disc to suck out the pigment processed in the grinding tank, some pigment particles that do not meet the fineness requirements are easily returned to the pigment tank along with the pigment that has been ground to meet the fineness requirements. This results in low efficiency of the circulating grinding process, requiring multiple grinding cycles to meet the fineness requirements, which increases production time and energy consumption. Utility Model Content

[0004] The technical problem this invention aims to solve is that, during the grinding process, uneven or insufficient grinding may occur. When finer pigment particles are required, during the process of drawing out the pigment processed in the grinding tank by forming a negative pressure in the dispersion disc, some pigment particles that do not meet the fineness requirements are easily returned to the pigment tank along with the qualified pigment. This results in low efficiency of the circulating grinding process, requiring multiple grinding cycles to meet the fineness requirements, which increases production time and energy consumption.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a cobalt blue pigment grinding machine, including a lifting base, a grinder fixedly installed on one side of the lifting base, a motor fixedly installed on one side of the grinder, a fixing frame fixedly installed on one side of the grinder, a grinding barrel fixedly installed on one side of the fixing frame, a pin through the grinder and the fixing frame, wherein one end of the pin is fixedly installed on the output end of the motor by means of a coupling, an impeller is fixedly installed on the outer surface of one end of the pin on the inner wall of the grinding barrel, a dispersing disc is fixedly installed on the outer surface of one end of the pin at the outlet of the grinding barrel, and an adjusting filter device is provided on the inner wall of the outlet of the dispersing disc. The adjusting filter device can slide the second filter disc on the first filter disc to a certain angle according to the pigment fineness requirements, so that the holes on the two filter discs are misaligned to form a new size of filter hole, thereby reducing the size of the filter hole and achieving a finer pigment fineness, while unqualified fineness is retained in the grinding barrel for further grinding.

[0006] Preferably, the adjusting filtration device includes two first filter discs, wherein a disassembly mechanism is provided between one side of the first filter disc and the inner wall of the outlet of the grinding barrel, and one end of the first filter disc is inserted into the inner wall of the outlet of the grinding barrel and located above the dispersing disc; a second filter disc, wherein both ends of the second filter disc are slidably installed in the inner wall of one side of the first filter disc; and a limiting mechanism, which is provided between the outer surfaces of the second filter disc and the second filter disc, for locking and fixing the second filter disc after it is rotated to a certain angle on the first filter disc.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up an adjustable filter device, when it is necessary to adjust according to the fineness requirements of the pigment, the second filter plate can be rotated to slide on the first filter plate to a certain angle, which will cause the holes on the first and second filter plates to be misaligned to form filter holes of a new size. Then, the adjusted second filter plate is fixed on the first filter plate by a limiting mechanism, thereby reducing the size of the filter holes and fixing it in place, so as to facilitate the filtration of finer pigments during grinding. Unqualified fineness will remain in the grinding barrel for further grinding. It can efficiently complete the grinding, refining and filtering of pigments, meet the needs of pigments with different fineness, and reduce production time and energy consumption.

[0008] Preferably, the limiting mechanism includes a plurality of stops, wherein one side of the stops is fixedly mounted on the outer surface of the first filter disc; a plurality of limiting rods, wherein one end of the limiting rod is rotatably mounted on the outer surface of the first filter disc, and one side abuts against one side of the stops; a plurality of torsion springs, wherein the two ends of the torsion springs are respectively fixedly mounted on the outer surface of the first filter disc and one side of the inner wall of one end of the limiting rod; two protrusions, wherein one side of the protrusions is fixedly mounted on the outer surface of the second filter disc; and two first springs, wherein the two ends of the first springs are respectively fixedly mounted on one side of the inner wall of the first filter disc and one side of the second filter disc.

[0009] The effect achieved by the above components is as follows: by setting a limiting mechanism, when the second filter disc slides on the first filter disc to a certain angle, the protrusion on the outer surface will push the limiting rod to rotate, the torsion spring will deform, and the first spring will be compressed. When it rotates to a suitable angle, the limiting rod will reset under the action of the torsion spring and abut against one side of the protrusion. At the same time, the first spring will drive the second filter disc to reset, so that the protrusion on its outer surface will reset and abut against the other side of the limiting rod, locking and fixing the second filter disc. This causes the holes on the first and second filter discs to be misaligned, forming a new size of filter hole and then fixing it, thereby reducing the size of the filter hole.

[0010] Preferably, the limiting mechanism further includes two telescopic plates, wherein the two ends of the telescopic plates are respectively fixedly installed on one side of the inner wall of the first filter disc and one side of the second filter disc.

[0011] The effect achieved by the above components is that the telescopic plate can cover the first spring inside the inner wall of the first filter disc, which can effectively isolate the pigment particles generated during the grinding process from direct contact with the first spring, prevent pigment particles from adhering to the spring surface and causing the spring to jam or rust, and ensure that the first spring always maintains good elastic performance.

[0012] Preferably, a circular roller is rotatably mounted on the inner wall of one end of the protrusion, wherein the outer surface of the circular roller rolls against one side of the limiting rod.

[0013] The effect achieved by the above components is that the roller can transform the sliding friction between the protrusion and the limiting rod into rolling friction, reducing the friction between the two, making the adjustment process of the second filter disc smoother and less labor-intensive, reducing the difficulty of adjustment operation, and improving the convenience of equipment adjustment.

[0014] Preferably, the easy-to-disassemble mechanism includes a plurality of recessed blocks, wherein the plurality of recessed blocks are symmetrically fixedly installed on the outer surface of the first filter disc, and the inner wall of the outlet of the grinding barrel is symmetrically provided with a first slot, a second slot is provided on one side of the inner wall of the first slot, and a locking hole is provided on one side of the inner wall of the second slot, wherein the recessed blocks are inserted into the first slot; a first locking block, wherein the two ends of the first locking block are respectively slidably installed in the inner walls of two opposite recessed blocks, and one end is inserted into the second slot; a second locking block, wherein one end of the second locking block is slidably installed in the inner wall of the first locking block, and one end is inserted into the locking hole; and a second spring, wherein the two ends of the second spring are respectively fixedly installed on one side of the inner wall of the first locking block and one side of the second locking block.

[0015] The effect achieved by the above-mentioned components is as follows: By setting up a disassembly mechanism, when grinding and processing cobalt blue pigment, the two first filter discs are first manually aligned with each other on the outer surface of one end of the pin, and the outer surface of one end of the pin is wrapped around it. Then, the two first filter discs are inserted into the inner wall of the outlet of the grinding barrel, so that the groove block and the first locking block on their outer surface are inserted into the first locking slot. Then, the second locking block is slid to one end in the inner wall of the first locking block to a certain position, which causes the second spring to contract. Then, the first locking block is pushed into the second locking slot to a certain position, so that the second locking block is locked into the locking hole under the reset action of the second spring. Thus, the two first filter discs and the second filter disc can be fixed in the inner wall of the outlet of the grinding barrel. Similarly, the reverse operation can be performed to disassemble them for easy replacement, maintenance and cleaning.

[0016] Preferably, the easy-release mechanism further includes two telescopic rods, wherein the outer surface of the telescopic rods is inserted into the inner wall of the second spring, and both ends are respectively fixedly installed on one side of the inner wall of the first locking block and one side of the second locking block.

[0017] The effect achieved by the above components is that the telescopic rod can effectively limit the second spring, prevent the second spring from shifting or twisting laterally during the extension and retraction process, ensure the stability of the elastic performance of the second spring, and thus ensure the reliability of the engagement between the second locking block and the locking hole, and improve the stability of the easy-to-disassemble mechanism.

[0018] Preferably, a limiting block is fixedly installed on one side of the first filter disc, and a limiting groove is formed on one side of the first filter disc, wherein the limiting block is inserted into the inner wall of the limiting groove.

[0019] The effect achieved by the above components is that this structural design enhances the tightness and stability of the connection between the two first filter discs, prevents relative displacement between the two first filter discs during operation, ensures the overall stability of the filter disc structure, and thus ensures the stable operation of the filtration process.

[0020] The beneficial effects of this utility model are:

[0021] By setting up an adjustable filtration device, when adjustments are needed according to the fineness requirements of the pigment, the second filter disc can be rotated to slide onto the first filter disc at a certain angle. This causes the holes on the first and second filter discs to misalign, forming filter holes of a new size. Then, a limiting mechanism fixes the adjusted second filter disc onto the first filter disc, thereby reducing the size of the filter holes and securing it in place. This facilitates the filtration of finer pigments during grinding, while unqualified pigments remain in the grinding barrel for further grinding. This system efficiently completes the grinding, refining, and filtering of pigments, meeting the needs of pigments with different fineness requirements and reducing production time and energy consumption.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Figure 1-7 The cobalt blue pigment grinding machine shown includes a lifting base 1. A grinder 3 is fixedly installed on one side of the lifting base 1, a motor 4 is fixedly installed on one side of the grinder 3, a fixing frame 5 is fixedly installed on one side of the grinder 3, and a grinding barrel 6 is fixedly installed on one side of the fixing frame 5. A pin 7 is installed through the grinder 3 and the fixing frame 5. One end of the pin 7 is fixedly installed on the output end of the motor 4 by means of a coupling. An impeller 8 is fixedly installed on the outer surface of one end of the pin 7 on the inner wall of the grinding barrel 6. A dispersing disc 9 is fixedly installed on the outer surface of one end of the pin 7 at the outlet of the grinding barrel 6. An adjusting filter device 2 is provided on the inner wall of the outlet of the dispersing disc 9. The adjusting filter device 2 can slide the second filter disc 22 on the first filter disc 21 to a certain angle according to the pigment fineness requirements, so that the holes on the two filter discs are misaligned to form a new size of filter hole, thereby reducing the size of the filter hole and achieving a finer pigment fineness. Unqualified fineness is retained in the grinding barrel 6 for further grinding. It should be noted that the grinder 3 is a mature technology and equipment in the existing technology, and its internal structure, connection method and principle will not be described further.

[0034] Figure 1-7The adjustable filter device 2 shown includes two first filter discs 21, wherein a disassembly mechanism 24 is provided between one side of the first filter disc 21 and the inner wall of the outlet of the grinding barrel 6, and one end of the first filter disc 21 is inserted into the inner wall of the outlet of the grinding barrel 6 and is located above the dispersion disc 9; a second filter disc 22, wherein the two ends of the second filter disc 22 are respectively slidably installed in the inner wall of one side of the first filter disc 21; and a limiting mechanism 23, which is provided between the outer surfaces of the second filter disc 22 and the second filter disc 22, and is used to lock and fix the second filter disc 22 after it is rotated on the first filter disc 21 to a certain angle. By setting up the adjustable filter device 2, when adjustment is needed according to the fineness requirements of the pigment, the second filter disk 22 can be rotated to slide on the first filter disk 21 to a certain angle, which will cause the holes on the first filter disk 21 and the second filter disk 22 to be misaligned to form filter holes of a new size. Then, the adjusted second filter disk 22 is fixed on the first filter disk 21 by the limiting mechanism 23, thereby reducing the size of the filter holes and fixing it in place, so as to facilitate the filtration of finer pigments during grinding. Unqualified fineness will remain in the grinding barrel 6 for further grinding. This can efficiently complete the grinding, refining and filtering of pigments, meet the needs of pigments with different fineness, and reduce production time and energy consumption.

[0035] Figure 1-7The limiting mechanism 23 shown includes several blocks 231, one side of which is fixedly mounted on the outer surface of the first filter disc 21; several limiting rods 232, one end of which is rotatably mounted on the outer surface of the first filter disc 21 and one side abuts against one side of the blocks 231; several torsion springs 233, the two ends of which are respectively fixedly mounted on the outer surface of the first filter disc 21 and one side of the inner wall of one end of the limiting rods 232; two protrusions 234, one side of which is fixedly mounted on the outer surface of the second filter disc 22; and two first springs 235, the two ends of which are respectively fixedly mounted on one side of the inner wall of the first filter disc 21 and one side of the second filter disc 22. By setting a limiting mechanism 23, when the second filter disc 22 slides on the first filter disc 21 to a certain angle, the protrusion 234 on its outer surface will push the limiting rod 232 to rotate, the torsion spring 233 will deform, and the first spring 235 will be compressed. When it rotates to a suitable angle, under the action of the torsion spring 233, the limiting rod 232 will reset and abut against one side of the protrusion 234. At the same time, the first spring 235 will drive the second filter disc 22 to reset, so that the protrusion 234 on its outer surface will reset and abut against the other side of the limiting rod 232, locking the second filter disc 22 in place. This causes the holes on the first filter disc 21 and the second filter disc 22 to be misaligned, forming new filter holes of a new size, which are then fixed in place, thereby reducing the size of the filter holes. The limiting mechanism 23 also includes two telescopic plates 236, the two ends of which are respectively fixedly installed on one side of the inner wall of the first filter disc 21 and one side of the second filter disc 22. The telescopic plate 236 can cover the first spring 235 within the inner wall of the first filter disc 21, effectively isolating pigment particles generated during the grinding process from direct contact with the first spring 235. This prevents pigment particles from adhering to the spring surface and causing spring jamming or corrosion, ensuring that the first spring 235 always maintains good elasticity. A roller 237 is rotatably mounted on the inner wall of one end of the protrusion 234, with the outer surface of the roller 237 rolling against one side of the limiting rod 232. The roller 237 can convert the sliding friction between the protrusion 234 and the limiting rod 232 into rolling friction, reducing the frictional force between them. This makes the rotation adjustment process of the second filter disc 22 smoother and less labor-intensive, reducing the difficulty of adjustment operations and improving the convenience of equipment adjustment.

[0036] Figure 1-7The disassembly mechanism 24 shown includes several grooved blocks 244, which are symmetrically fixedly installed on the outer surface of the first filter disc 21. The inner wall of the outlet of the grinding barrel 6 is symmetrically provided with first slots 241, and a second slot 242 is provided on one side of the inner wall of the first slot 241. A locking hole 243 is provided on one side of the inner wall of the second slot 242. The grooved blocks 244 are inserted into the first slots 241. A first locking block 245 is provided, with its two ends slidably installed in the inner walls of two opposite grooved blocks 244, and one end inserted into the second slot 242. A second locking block 247 is provided, with one end slidably installed in the inner wall of the first locking block 245, and one end inserted into the locking hole 243. A second spring 246 is provided, with its two ends fixedly installed on one side of the inner wall of the first locking block 245 and one side of the second locking block 247. By setting up a disassembly mechanism 24, when grinding and processing cobalt blue pigment, firstly, manually align the two first filter discs 21 with each other on the outer surface of one end of the pin 7, wrapping the outer surface of one end of the pin 7. Then, insert the two first filter discs 21 into the inner wall of the outlet of the grinding barrel 6, so that the groove block 244 and the first locking block 245 on their outer surfaces are inserted into the first locking groove 241. Then, slide the second locking block 247 to one end in the inner wall of the first locking block 245 to a certain position, causing the second spring 246 to contract. Then push the first locking block 245 to lock it into the second locking groove 242 to a certain position, so that the second locking block 247 is locked into the locking hole 243 under the reset action of the second spring 246. Thus, the two first filter discs 21 and the second filter disc 22 can be fixed in the inner wall of the outlet of the grinding barrel 6. Similarly, the reverse operation can be performed to disassemble them for easy replacement, maintenance and cleaning.

[0037] Figure 1-7 The disassembly mechanism 24 also includes two telescopic rods 248. The outer surface of the telescopic rods 248 is inserted into the inner wall of the second spring 246, and both ends are fixedly installed on one side of the inner wall of the first locking block 245 and one side of the second locking block 247, respectively. The telescopic rods 248 can effectively limit the second spring 246, preventing the second spring 246 from shifting or twisting laterally during extension and retraction, ensuring the stability of the elastic performance of the second spring 246, thereby ensuring the reliability of the engagement between the second locking block 247 and the locking hole 243, and improving the stability of the disassembly mechanism 24. A limiting block 249 is fixedly installed on one side of the first filter disc 21, and a limiting groove 2410 is formed on one side of the first filter disc 21, in which the limiting block 249 is inserted into the inner wall of the limiting groove 2410. This structural design enhances the tightness and stability of the connection between the two first filter discs 21, prevents relative displacement between the two first filter discs 21 during operation, ensures the stability of the overall structure of the filter disc, and thus ensures the stable operation of the filtration process.

[0038] Working principle: When grinding and processing cobalt blue pigment, firstly, manually align the two first filter discs 21 with each other on the outer surface of one end of the pin 7, wrapping the outer surface of one end of the pin 7. Then, insert the limiting block 249 on one of the first filter discs 21 into the limiting groove 2410 on the other first filter disc 21. Next, insert the two first filter discs 21 into the inner wall of the outlet of the grinding barrel 6, so that the groove block 244 and the first locking block 245 on their outer surfaces are inserted into the first locking groove 241. Then, slide the second locking block 247 to one end in the inner wall of the first locking block 245 to a certain position, causing the second spring 246 to contract, and then push the first locking block 245 to lock it into the second locking groove 241. 42 is positioned so that the second locking block 247 is engaged in the locking hole 243 under the reset action of the second spring 246, thereby fixing the two first filter discs 21 and the second filter disc 22 in the inner wall of the outlet of the grinding barrel 6. When adjustment is required according to the pigment fineness requirements, the second filter disc 22 can be rotated so that it slides on the first filter disc 21 to a certain angle. The protrusion 234 on the outer surface will push the limiting rod 232 to rotate, the torsion spring 233 will deform, and the first spring 235 will be compressed. When rotated to a suitable angle, the limiting rod 232 will reset under the action of the torsion spring 233 and abut against one side of the protrusion 234. At the same time, the first spring 235 will drive the second filter disc 22 to reset, so that its outer surface... The protrusion 234 on the surface resets and abuts against the other side of the limiting rod 232, locking and fixing the second filter disc 22. This causes the holes on the first filter disc 21 and the second filter disc 22 to misalign, forming new filter holes of a new size, which are then fixed in place. This reduces the size of the filter holes, achieving a finer pigment fineness. Unqualified pigments remain in the grinding barrel 6 for further grinding. This process efficiently completes the grinding, refining, and filtering of pigments, meeting the needs of pigments with different fineness, and reducing production time and energy consumption. During grinding, the pigment barrel containing cobalt blue pigment is placed on one side of the lifting base 1. Then, the hydraulic rod inside the lifting base 1 is activated to drive the grinder 3 downward to a certain position, which in turn drives the motor 4 and the fixed... The fixed frame 5 and the grinding barrel 6 move downwards, so that one end of the grinding barrel 6 and the fixed frame 5 are inserted into the pigment barrel. Then, the motor 4 on one side is started, which drives the rod pin 7 to rotate. This drives the impeller 8 and the dispersing disc 9 to rotate at the bottom outlet of the inner wall of the grinding barrel 6. The rotation of the impeller 8 will suck the cobalt blue pigment in the pigment barrel from the inlet of the grinding barrel 6. When the rod pin 7 drives the impeller 8 to rotate, it will also drive the zirconium beads placed in the grinding barrel 6 to move at high speed. The beads collide with each other and generate extrusion, shearing and impact forces, breaking up the agglomeration of the pigment particles and refining the particles, thus achieving the grinding effect. Then, the dispersing disc 9 rotates at the bottom outlet of the grinding barrel 6, which will generate negative pressure to suck the material out and return it to the pigment barrel.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
