Description

Technical Field

[0001] The invention relates to the field of alumina slurry preparation, in particular to a slurry stirring and grinding device for alumina production, and in particular to a process for the slurry stirring and grinding device for alumina production. Background Art

[0002] Alumina, chemical formula Al2O3, is a high hardness compound. Alumina is a stable oxide of aluminum with the chemical formula Al2O3. It is also called bauxite in mining, ceramics and materials science. Alumina sintered at high temperature is called artificial corundum or artificial gemstone. Corundum powder has high hardness and can be used as abrasive and polishing powder.

[0003] Chinese patent: CN101747027A; discloses a method for preparing alumina ceramic slurry, by adding γ-Al2O3 to a mineralizer composed of one or a combination of NH4Cl and MgCl2·6H2O, calcining it to form a-Al2O3; then grinding the a-Al2O3 into fine powder, adding a dispersant polyacrylamide and water, and grinding it to form an alumina slurry.

[0004] Due to the high hardness of alumina itself, it can be used as an abrasive. After calcination, it is necessary to add the alumina solid, the dispersant polyacrylamide and water into the grinder to form a grinding liquid for grinding. During the grinding process, the inside of the grinder may be damaged by the alumina, which may cause impurities in the alumina, resulting in unclear composition of the alumina powder. In addition, since it is added to the grinder all at once, the grinding time of the alumina is relatively long, and the degree of dispersion of the alumina in the slurry cannot be known in time, which may cause the concentration of the alumina slurry to fail to meet the required requirements, rendering the entire alumina slurry unusable.

[0072] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0073] See Figures 1 to 17As shown, a slurry stirring and grinding equipment for alumina production includes a mounting frame 1 and a clamping plate 2, the clamping plate 2 is rotatably arranged on the mounting frame 1 in an inclined state, the clamping plate 2 is provided with a grinding plate clamping mechanism 3 for fixing the grinding plate, and also includes a grinding rod clamping mechanism 4, a sprinkling mechanism 5 and a collecting mechanism 6; the grinding rod clamping mechanism 4 is arranged on the mounting frame 1 and is located above the clamping plate 2, the grinding rod clamping mechanism 4 includes a rotating plate 41 that can move toward the direction close to the clamping plate 2, the rotating plate 41 can rotate and the rotating plate 41 can move back and forth along the radial direction of the clamping plate 2, and a clamp 42 for clamping the grinding rod is arranged on the side of the rotating plate 41 close to the clamping plate 2; the sprinkling mechanism 5 is arranged between the clamping plate 2 and the rotating plate 41, and the sprinkling mechanism 5 is used to spray grinding liquid on the contact surface between the grinding rod and the grinding plate; the collecting mechanism 6 is arranged on the frame and is used to collect and stir the grinding liquid and the alumina grinding material.

[0074] The staff clamps and fixes the grinding disc through the grinding disc clamping mechanism 3, and clamps and fixes the grinding rod through the clamp 42 set on the rotating disc 41. The grinding disc and the grinding rod are both made of aluminum oxide, which can avoid the generation of impurities during the grinding process and improve the purity of the slurry. Subsequently, the clamping disc 2 is adjusted to rotate, thereby driving the grinding disc to rotate, and the rotating disc 41 pushes the grinding rod to move in the direction close to the clamping disc 2. The clamping disc 2 is arranged in parallel with the rotating disc 41. As the rotating disc 41 approaches, the grinding rod and the grinding disc are in contact with each other. Subsequently, the rotating disc 41 and the clamping disc 2 rotate respectively, so that the grinding rod and the grinding disc are ground. Grinding, at this time, the sprinkling mechanism 5 sprays grinding liquid on the contact surface between the grinding rod and the grinding disc, and the clamping disc 2 is in an inclined state. The grinding liquid can flush the ground alumina out from between the grinding disc and the grinding rod along the inclined clamping disc 2, thereby avoiding the accumulation of ground powder between the grinding rod and the grinding disc, which leads to a decrease in grinding effect. The collecting mechanism 6 is located at the lower end of the clamping disc 2 in the inclined direction. The mixture of grinding liquid and alumina is collected and stirred by the collecting mechanism 6, thereby improving the mixing degree of the alumina slurry, and the clamping disc 2 can move back and forth along the radial direction of the clamping disc 2, thereby increasing the contact range between the grinding rod and the grinding disc and improving the utilization rate of the grinding disc.

[0075] See also Figures 1 to 4As shown, the grinding rod clamping mechanism 4 further includes a U-shaped plate 43, a sliding block 44 and a reciprocating assembly 45; the U-shaped plate 43 is arranged on the mounting frame 1 and is located above the clamping disc 2. A first strip-shaped chute 431 is arranged on the U-shaped plate 43. The sliding block 44 is slidably arranged in the first strip-shaped chute 431. A hydraulic rod 441 is arranged on the side of the sliding block 44 away from the clamping disc 2. The actuator of the hydraulic rod 441 passes through the sliding block 44 and is provided with a motor chamber 442. The motor chamber 442 is located between the U-shaped plate 43 and the clamping disc 2. A first servo motor 443 is arranged in the motor chamber 442. The output shaft of the first servo motor 443 passes through the motor chamber 442 and is arranged at the center of the rotating disc 41. The reciprocating assembly 45 is arranged on the U-shaped plate 43 and is used to make the sliding block 44 reciprocate in the first strip-shaped chute 431.

[0076] The reciprocating assembly 45 includes a limiting plate 451, an oval mounting frame 452 and a second servo motor 453; there are two limiting plates 451, and the two limiting plates 451 are mirror-symmetrically arranged on the side of the U-shaped plate 43 away from the clamping disc 2. The oval mounting frame 452 is arranged between the two limiting plates 451. Two limiting strips 4521 are arranged on the oval mounting frame 452. Each limiting plate 451 is provided with a limiting groove 4511. The limiting strips 4521 are slidably arranged in the corresponding limiting grooves 4511. The sliding block 44 is connected to the oval mounting frame 452 through a connecting strip 444. A plurality of first round teeth 4522 are arranged on the inner walls of both sides of the oval mounting frame 452 along the long axis direction. The second servo motor 453 is arranged on the U-shaped plate 43. A sector gear 4531 is arranged on the output shaft of the second servo motor 453. The sector gear 4531 is located inside the oval mounting frame 452. Adjust the first servo motor 443. The first servo motor 443 drives the rotating disc 41 to rotate. As the rotating disc 41 rotates, it drives the grinding rod to rotate. Then adjust the second servo motor 453. The second servo motor 453 drives the sector gear 4531 to rotate. The sector gear 4531 intermittently meshes with the first round teeth 4522 on the inner walls of both sides of the oval mounting frame 452, so that the oval mounting frame 452 can reciprocate between the two limiting plates 451. The oval mounting frame 452 cooperates with the limiting grooves 4511 of the limiting plates 451 through the limiting strips 4521, so as to ensure the stability of the movement of the oval mounting frame 452 and prevent the sector gear 4531 from being offset from the rack of the oval mounting frame 452 and unable to mesh. As the oval mounting frame 452 moves, it drives the sliding block 44 to reciprocate in the first strip-shaped chute 431. As the sliding block 44 moves, the grinding rod can reciprocate along the length direction of the first strip-shaped chute 431, so that the contact range of the grinding rod with the grinding disc is increased. After grinding for a period of time, by adjusting the hydraulic rod 441, the hydraulic rod 441 pushes the grinding rod towards the direction close to the grinding disc, so that the grinding rod fits with the grinding disc, and continuous grinding can be carried out.

[0077] See also Figure 7 , Figure 8 , Fig.12 and Fig.14 As shown, the watering mechanism 5 includes a horizontal plate 51, an L-shaped sliding plate 52 and an arc-shaped water spraying chamber 53; the horizontal plate 51 is arranged on one side of the motor chamber 442 and is located at the upper end of the clamping plate 2 in the tilting direction, the horizontal plate 51 is arranged parallel to the rotating plate 41, and a vertical plate 511 is arranged at one end of the horizontal plate 51 away from the motor chamber 442, the vertical plate 511 and the horizontal plate 51 are perpendicular to each other, and a slot 5111 is arranged at one end of the vertical plate 511 away from the horizontal plate 51, one end of the L-shaped sliding plate 52 can be slidably arranged in the slot 5111, and the other end of the L-shaped sliding plate 52 is parallel to the clamping plate 2 It is arranged and faces the center of the rotating disk 41; two guide rods 521 are arranged at one end of the L-shaped sliding plate 52 extending into the slot 5111, and the two guide rods 521 are both sleeved with a compression spring 521; the vertical plate 511 is provided with two guide holes 5112 connected to the slot 5111, and the guide rods 521 can be slidably arranged in the corresponding guide holes 5112; the arc-shaped water spraying bin 53 is arranged at one end of the L-shaped sliding plate away from the vertical plate 511, and an arc-shaped water spraying groove 531 is arranged at the bottom of the inner wall of the arc-shaped water spraying bin 53, and the arc-shaped water spraying groove 531 faces the contact position between the grinding disc and the grinding rod.

[0078] As the rotating disk 41 and the clamping disk 2 rotate, the grinding rod and the grinding disk contact each other and grind each other. The arc-shaped water spray chamber 53 is located at the upper end of the inclined surface of the clamping disk 2 and the arc-shaped water spray chamber 53 fits the outer wall of the grinding rod. The arc-shaped water spray chamber 53 sprays grinding liquid at multiple angles toward the contact position of the grinding rod and the grinding disk through the arc-shaped water spray groove 531. The grinding liquid moves in the direction close to the collecting mechanism 6 as the inclined grinding disk is arranged. The arc-shaped water spray chamber 53 can intercept the grinding liquid and the ground aluminum oxide, so that the ground aluminum oxide flows out from between the grinding rod and the grinding disk to avoid its accumulation. In addition, the outer wall of the arc-shaped water spray chamber 53 is also provided with an annular mounting plate 81532, and a plurality of universal wheels 5321 are provided on the annular mounting plate 81532. With the assistance of the universal wheels 5321, the arc-shaped water spray chamber 53 can slide on the clamping disk 2 as the rotating disk 41 moves, thereby avoiding the arc-shaped water spray chamber 53 from contacting the grinding disk. When the hydraulic rod 441 pushes the grinding rod to move, the L-shaped sliding plate 52 moves along the slot 5111, and the guide rod 521 on the L-shaped sliding plate 52 slides along the corresponding guide hole 5112, thereby squeezing the corresponding compression spring 5211. A limiting disk 522 is also provided at one end of each guide rod 521 extending out of the guide hole 5112, thereby preventing the L-shaped sliding plate 52 from being pushed out of the slot 5111 under the elastic force of the compression spring 5211. With the elastic force of the compression spring, the arc-shaped water spraying groove 531 of the arc-shaped water spraying bin 53 can always be above the contact position between the grinding rod and the grinding disc, so that the sprayed grinding liquid can flush out the alumina grinding material between the grinding rod and the grinding disc along the arc-shaped water spraying groove 531, and the clamping disc 2 is set in an inclined state, so that the alumina grinding material and the grinding liquid can automatically slide into the collecting mechanism 6 under the action of gravity, thereby avoiding residue.

As the rotating disk 41 slowly rotates, the guide bar 411 is tilted at a certain angle, and the guide bar 411 contacts the guide rod 713 on the guide block 71, thereby pushing the guide block 71 to slide along the elliptical groove 512. The second connecting portion 513 is located at one end of the top of the horizontal plate 51 close to the center of the rotating disk 41 and close to the focus of the elliptical groove 512. The reset tension spring 712 is pulled to generate an elastic force. When the guide block 71 moves to the focus position of the elliptical groove 512 away from the second connecting portion 513, due to the elastic force of the tension spring, the guide block 71 is 1 cannot slide along the semicircular surface of the elliptical groove 512. Under the action of the elastic component 8, the guide bar 411 can rotate along its rotation position, so that the guide bar 411 is set at another angle, thereby providing a thrust for the guide block 71. As the rotating disk 41 continues to rotate, the angle of the guide bar 411 gradually increases, thereby pushing the guide block 71 to slide along the semicircular surface of the elliptical groove 512 away from the second connecting portion 513. Under the elastic force of the reset tension spring 712, the guide block 71 contacts the blocking block 5122. The end of the blocking block 5122 away from the rectangular notch 5121 is set in a semicircular shape, thereby pushing the blocking block 5122 toward the adjacent portion. The guide bar 411 is moved toward the inner wall of the bottom of the rectangular notch 5121. When the rectangular through groove 51221 on the blocking block 5122 is connected to the first through hole 514, a space for the grinding liquid to pass through is formed between the external water supply pipe, the rectangular through groove 51221 and the connecting pipe 72. The grinding liquid enters the arc-shaped water spraying chamber 53 through this space, thereby flushing the contact position between the grinding rod and the grinding disc in the grinding state. Subsequently, the guide bar 411 is reset with the cooperation of the elastic component 8, so as to make the next contact with the guide rod 713, thereby avoiding continuous spraying of the grinding liquid resulting in excessive use of the grinding liquid, resulting in the formed alumina slurry being too thin. The connecting pipe 72 includes the first A delivery pipe 721 and a second delivery pipe 722; one end of the first delivery pipe 721 is arranged in the first through hole 514, and the end of the first delivery pipe 721 away from the first through hole 514 is slidably arranged on the inner wall of the second delivery pipe 722, and a piston 7211 is arranged on the end of the first delivery pipe 721 extending into the second delivery pipe 722. The second delivery pipe 722 is L-shaped, and the end of the second delivery pipe 722 away from the first delivery pipe 721 extends into the arc-shaped water spraying tank 53. Through the cooperation of the first delivery pipe 721 and the piston 7211, the first delivery pipe 721 and the second delivery pipe 722 can adjust the corresponding distance as the grinding rod is consumed to avoid breakage.

[0081] See also Fig.14 and Fig.15As shown, guide grooves 51211 are arranged on the inner walls on both sides of the rectangular notch 5121, guide slide bars 51222 corresponding to the slide grooves are arranged on both sides of the blocking block 5122, and the guide slide bars 51222 are slidably arranged in the guide grooves 51211, and two resistance rods 51212 are mirror-imaged on the inner wall at the bottom of the rectangular notch 5121, and each resistance rod 51212 is sleeved with a resistance spring 51213, and two sliding holes 51223 for accommodating the resistance rod 51212 are arranged on one side of the blocking block 5122 close to the resistance rod 51212.

[0082] By providing a resistance spring 51213, when the guide block 71 is not in contact with the blocking block 5122, under the action of the resistance spring 51213, the rectangular through groove 51221 and the first through hole 514 are in a non-connected state. When the guide block 71 is in contact with the blocking block 5122, the guide slide bar 51222 on the blocking block 5122 slides along the corresponding guide slide groove 51211, thereby ensuring the stability of the movement of the blocking block 5122, and the two resistance rods 51212 extend into the corresponding sliding holes 51223. At this time, the rectangular through groove 51221 is connected with the first through hole 514, and the grinding liquid enters the arc-shaped water spraying bin 53 through the connecting space, thereby spraying the contact position between the grinding rod and the grinding disc. When away from the blocking block 5122, under the action of the elastic force of the resistance spring 51213, the blocking block 5122 is pushed to move in the direction away from the bottom inner wall of the rectangular notch 5121, and the blocking block 5122 blocks the first perforation 514 to prevent the grinding liquid from entering the arc-shaped water spraying bin 53, thereby realizing intermittent water supply to the arc-shaped water spraying bin 53. A resistance plate 5123 is also provided on the side of the elliptical slide 512 close to the rectangular notch 5121, and a strip groove 51231 is provided on the resistance plate 5123 for the blocking plate to pass through. When the guide slide 51222 moves to the rectangular notch 5121, it will contact the resistance plate 5123, thereby preventing the blocking block 5122 from being pushed out of the rectangular notch 5121 due to the elastic force of the resistance spring 51213.

[0084] Two guide grooves 8112 are arranged on the inner wall of each first circular hole 8111, and the two guide grooves 8112 are arranged in a mirror image with respect to the axis of the corresponding first circular hole 8111. Two guide bars 821 corresponding to the guide grooves 8112 are arranged on the outer wall of one end of the sliding column 82 close to the first circular hole 8111, and the guide bars 821 can be slidably arranged in the corresponding guide grooves 8112, so as to ensure the stability of the movement of the sliding column 82. When the guide bar 411 pushes the guide block 71 to move to the position where the elliptical slide groove 512 is away from the second connecting portion 513, the guide bar 411 can rotate along the rotation position due to the elastic force of the reset tension spring 712. At this time, the sliding column 82 hinged to the guide bar 411 slides along the first circular hole 8111, thereby squeezing the corresponding push spring 83. , the pushing spring 83 generates an elastic force, and the guide bar 411 is set in an inclined state, so that the pushing guide block 71 can slide along the semicircular surface of the elliptical slide groove 512. A limiting ring 812 is also provided at the end of the mounting column 811 away from the mounting plate 81, and a limiting hole 8121 is provided on the limiting ring 812 for the sliding column 82 to pass through. As the rotating disk 41 continues to rotate, under the action of the elastic force of the pushing spring 83, the sliding column 82 moves in a direction away from the bottom inner wall of the first circular hole 8111. When the guide bar 821 contacts the limiting ring 812, the position of the sliding column 82 is restricted, so that the guide bar 411 is reset, so as to make the next contact, thereby preventing the guide bar 411 from being pushed out of the corresponding first circular hole 8111 due to the elastic force of the pushing spring 83.
