Description

Technical Field

[0001] The invention belongs to the technical field of ball mills, in particular to an adjustable ball mill for producing metallic pigments. Background Art

[0002] Metallic pigments are a special type of pigment, which have been around for a long time in the history of human civilization. With the development of modern industry, the demand for metal powders is increasing, and the types are also increasing. Common metal powders include aluminum powder, zinc powder, and lead powder. Metal powders in alloy form include copper-zinc powder (commonly known as gold powder), zinc-aluminum powder, and stainless steel powder.

[0003] During the processing of metallic pigments, a ball mill is needed to grind the metal materials. The working principle of the ball mill is mainly driven by an electric motor to rotate the cylinder, the grinding balls inside, and the materials together. During the rotation, the grinding balls will be lifted to a certain height due to the centrifugal force and friction, and then fall down due to their own gravity, which will impact and grind the materials in the cylinder.

[0004] When processing metallic pigments, the crushed metal raw materials are first introduced into the cylinder, and then the driving device drives the cylinder to rotate, thereby driving the grinding balls and the raw materials to rotate. The grinding balls will be lifted to a certain height due to the centrifugal force and friction, and then fall down due to their own gravity, impacting and grinding the metal raw materials in the cylinder, thereby grinding the metal raw materials into powder.

[0005] At present, the length of the ball mill cylinder is fixed. In the process of ball milling metal raw materials, if the amount of raw materials fed into the ball mill is greater than the grinding amount of the ball mill itself, the equipment load will increase and the grinding efficiency will be reduced. If the amount of raw materials fed into the ball mill is less than the grinding amount of the ball mill itself, the operating cost of the ball mill will increase. Summary of the invention

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0049] Embodiment 1:

[0050] like Figures 1 to 11 As shown, the adjustable ball mill for producing metallic pigments of the present invention comprises a cylinder 1; a support frame is installed at the bottom of the cylinder 1; a feed end cover 11 is installed at the left end of the cylinder 1; a feed device 12 is installed on the feed end cover 11; the cylinder 1 is driven by a rotating device 13;

[0051] The inner ring surface of the cylinder 1 is provided with an evenly arranged inner lining plate 14 by bolts; a plurality of grinding balls of different sizes are placed in the cylinder 1;

[0052] An adjusting device is installed on the right side of the cylinder 1; the adjusting device includes a mounting frame 2; the mounting frame 2 is fixedly installed on the supporting frame;

[0053] A circular groove 21 is provided on the top of the mounting frame 2; a discharge pipe 22 is slidably connected in the circular groove 21, and the discharge pipe 22 can slide back and forth in the circular groove 21; a discharge baffle 3 is provided on one side of the cylinder 1 where the discharge pipe 22 extends, and the outer ring surface of the discharge baffle 3 is in contact with the inner lining plate 14; a rotating ring 31 is provided on the side of the discharge baffle 3 facing the discharge pipe 22, and the discharge pipe 22 rotates in the rotating ring 31 and cannot be separated from the rotating ring 31;

[0054] A feed groove 23 is provided on the outer surface of the discharge pipe 22 at one side of the discharge baffle plate 3; the discharge baffle plate 3 is provided with evenly arranged discharge grooves 32, and the grinding balls cannot pass through the discharge grooves 32;

[0055] The end surface of the discharge baffle plate 3 facing the discharge pipe 22 is fixedly connected with a spiral plate 4; the discharge pipe 22 passes through the middle of the spiral plate 4; an auger 24 is provided in the discharge pipe 22, and one end of the auger 24 is fixedly mounted on the discharge baffle plate 3;

[0056] A cover 5 is slidably disposed in the cylinder 1 on the right side of the discharge baffle 3, and the outer ring surface of the cover 5 is in contact with the inner lining plate 14; the discharge pipe 22 passes through the cover 5, and when the cover 5 rotates, it rotates around the discharge pipe 22, and at the same time, the cover 5 slides left and right on the discharge pipe 22;

[0057] The right end surface of the cover 5 is fixedly connected to a plurality of elongated shafts 51; the side of the elongated shafts 51 away from the cover 5 is fixedly connected to a first slider 52; the side of the elongated shafts 51 away from the cover 5 is provided with a first full-circle guide rail 53, and the first slider 52 slides on the first full-circle guide rail 53;

[0058] The first hydraulic cylinder 54 is installed on the support frame at the upper and lower sides of the discharge pipe 22, and the extended end of the first hydraulic cylinder 54 is fixedly installed on the first full-circle guide rail 53;

[0059] Specifically, when grinding the metal raw material, the ball mill is first started, the driving device drives the cylinder 1 to rotate, and the cylinder 1 drives the inner lining plate 14 and the grinding balls inside the cylinder 1 to circulate, and then the metal raw material is introduced into the cylinder 1 through the feeding device 12. When the metal raw material enters the cylinder 1, the metal raw material and the grinding balls will circulate along the inner lining plate 14, and the grinding balls will be lifted to a certain height due to the centrifugal force and friction, and then fall due to their own gravity, which will impact and grind the metal raw material in the cylinder 1;

[0060] More specifically, during the rotation of the cylinder 1, the discharge baffle 3 that is in contact with the inner lining plate 14 will also rotate in a circular manner with the inner lining plate 14. Since the discharge pipe 22 rotates in the rotating ring 31, the discharge pipe 22 will not rotate with the discharge baffle 3. At the same time, the discharge baffle 3 will drive the spiral plate 4 to rotate together. When the metal raw material is gradually ground into powder, the powder will enter the right side of the discharge baffle 3 through the discharge trough 32 opened on the discharge baffle 3 and be located between the discharge baffle 3 and the cover 5. When the powder enters the right side of the discharge baffle 3, the powder will fall on the spiral plate 4. In the spiral plate 4, since the spiral plate 4 rotates with the discharge baffle 3, the rotating spiral plate 4 will gradually drive the powder to move upward. When the powder moves to the middle position of the spiral plate 4, the rotating spiral plate 4 will push the powder into the feed groove 23 provided on the discharge pipe 22, and then the powder will enter the discharge pipe 22. Since the auger 24 is fixedly installed on the discharge baffle 3, the auger 24 will be driven to rotate during the rotation of the discharge baffle 3. The rotating auger 24 will push the powder entering the discharge pipe 22 to move, and finally be pushed out from the end of the discharge pipe 22.

[0061] Furthermore, since the cover 5 fits the inner lining plate 14, the cover 5 will also be driven to rotate during the rotation of the cylinder 1, and the cover 5 will drive the evenly arranged extension shafts 51 to rotate. Since the first slider 52 fixedly connected to the extension shaft 51 slides on the first full-circle guide rail 53, the extension shaft 51 will drive the first slider 52 to circulate on the first full-circle guide rail 53 during the rotation of the extension shaft 51 driven by the cover 5. When the amount of metal raw material introduced into the cylinder 1 is less than the grinding amount of the ball mill itself, the first hydraulic cylinder 54 is controlled to extend, and the first hydraulic cylinder 54 will push the first full-circle guide rail 53 to move toward the inside of the cylinder 1. At the same time, the first full-circle guide rail 53 is The circular guide rail 53 will push the extension shaft 51 to move, and the extension shaft 51 will push the cover 5 to move into the cylinder 1. At the same time, the cover 5 will push the spiral plate 4 and the discharge baffle 3 to move into the cylinder 1 along the inner lining plate 14. When the discharge baffle 3 moves into the cylinder 1, the distance between the discharge baffle 3 and the feed end cover 11 becomes smaller. When the distance between the discharge baffle 3 and the feed end cover 11 becomes smaller, the grinding space between the discharge baffle 3 and the feed end cover 11 is reduced, thereby reducing the grinding amount of the raw material inside the cylinder 1, avoiding the increase of the equipment load and the reduction of the grinding efficiency when the amount of raw material in the ball mill is greater than the grinding amount of the ball mill itself.

[0062] At the same time, when the amount of metal raw material introduced into the cylinder 1 is greater than the grinding amount of the ball mill itself, the first hydraulic cylinder 54 is controlled to contract. When the first hydraulic cylinder 54 contracts, it will drive the first full-circle guide rail 53, the sealing cover 5, the spiral plate 4 and the discharge baffle 3 to move to the right. When the discharge baffle 3 moves to the right, the distance between the discharge baffle 3 and the feed end cover 11 becomes larger. When the distance between the discharge baffle 3 and the feed end cover 11 becomes larger, the grinding space between the discharge baffle 3 and the feed end cover 11 increases, thereby increasing the grinding amount of the raw material inside the cylinder 1, avoiding the situation where the amount of raw material in the ball mill is less than the grinding amount of the ball mill itself, which will increase the working cost of the ball mill.

[0063] Embodiment 2:

[0064] The cover 5 is provided with a spiral groove 55, and the spiral plate 4 passes through the spiral groove 55 and extends to the right side of the cover 5;

[0065] The length of the feed trough 23 is the same as the length of the spiral plate 4;

[0066] A second full-circle guide rail 41 is fixedly connected to one end surface of the spiral plate 4 extending to the right side of the cover 5; two mounting plates 42 are fixedly connected to one side of the first full-circle guide rail 53 close to the mounting frame 2; and a second hydraulic cylinder 43 is fixedly mounted on the two mounting plates 42;

[0067] A second slider 44 is fixedly connected to the extended end of the second hydraulic cylinder 43, and the other end of the second slider 44 slides on the second full-circle guide rail 41;

[0068] In this embodiment, a cylinder 56 is fixedly connected to one side of the cover 5 facing the first full-circle guide rail 53, and the discharge pipe 22 passes through the cylinder 56; the cylinder 56 fits the discharge pipe 22 and seals the feed slot 23 located on the right side of the cover 5;

[0069] In this embodiment, the outer ring surface of the discharge baffle plate 3 is provided with evenly arranged notches 33, and the notches 33 correspond to the discharge slots 32 one by one;

[0070] The end surface of the sealing cover 5 facing the discharge baffle 3 is fixedly connected with uniformly arranged limit plates 34; the end surface of the limit plate 34 facing the slot 33 is gradually inclined toward the center of the discharge baffle 3;

[0071] An adjustment plate 35 is slidably connected in the discharge chute 32; a slide groove 36 is provided on the discharge baffle 3 on one side of the adjustment plate 35 facing the center of the discharge baffle 3, and the adjustment plate 35 slides in the slide groove 36; the adjustment plate 35 is connected to the slide groove 36 via a spring;

[0072] A push rod 37 is fixedly connected to the end surface of the adjustment plate 35 facing the notch 33, and the push rod 37 extends into the notch 33 and contacts the limit plate 34;

[0073] Specifically, since the second hydraulic cylinder 43 is fixedly connected to the mounting plate 42 fixedly connected to the first full-circular guide rail 53, and the second sliding block 44 fixedly connected to the second hydraulic cylinder 43 slides on the second full-circular guide rail 41, when the first full-circular guide rail 53 moves left and right, it will drive the mounting plate 42 and the second hydraulic cylinder 43 on the mounting plate 42 to move left and right. At the same time, the second hydraulic cylinder 43 drives the second full-circular guide rail 41 to move left and right through the second sliding block 44. Since the second full-circular guide rail 41 is fixedly connected to the spiral plate 4, it will drive the spiral plate 4 to move left and right. Since the spiral plate 4 is fixedly connected to the discharge baffle 3, when the cover 5 moves left and right, it will drive the discharge baffle 3 to move left and right.

[0074] More specifically, when the discharge amount of the powder needs to be increased, the second hydraulic cylinder 43 is controlled to extend, and the second hydraulic cylinder 43 will push the second full-circle guide rail 41 to move left, and at the same time, the second full-circle guide rail 41 will drive the spiral plate 4 to move left in the spiral groove 55, and at the same time, the spiral plate 4 will drive the discharge baffle plate 3 to move left. Since the discharge pipe 22 rotates in the swivel 31, the discharge baffle plate 3 will drive the discharge pipe 22 to move left through the swivel 31. In the process of the discharge pipe 22 moving to the left, the discharge pipe 22 will gradually pass through the middle of the cover 5, and at the same time, more parts of the feed trough 23 opened on the discharge pipe 22 will gradually move to the left side of the cover 5. At the same time, since the limit plate 34 is fixed to the cover 5, the notch 33 opened on the discharge baffle plate 3 will move along the limit plate 34. The surface of the limit plate 34 gradually inclines toward the center of the discharge baffle plate 3. Therefore, in the process of the discharge baffle plate 3 gradually moving to the left, the inclined surface of the limit plate 34 will gradually squeeze the push rod 37. When the push rod 37 is squeezed, it will move toward the center of the discharge baffle plate 3 and push the adjustment plate 35 to slide into the slide groove 36. When the adjustment plate 35 moves into the slide groove 36, the adjustment plate 35 will reduce the obstruction to the discharge chute 32. Therefore, the overall space of the discharge chute 32 will become larger, so that more powder passing through the discharge chute 32 will increase. At the same time, when the spiral plate 4 moves to the left, the distance between the discharge baffle plate 3 and the sealing cover 5 will increase. Therefore, the area of ​​the spiral plate 4 between the discharge baffle plate 3 and the sealing cover 5 will also increase. When the space of the discharge chute 32 and the area of ​​the spiral plate 4 are increased, more ground powder can be obtained, thereby increasing the discharge amount of the powder.

[0075] At the same time, when the discharge amount of the powder needs to be reduced, the second hydraulic cylinder 43 is controlled to contract, thereby indirectly moving the spiral plate 4 and the discharge baffle 3 to the right. When the discharge baffle 3 moves to the right, the adjustment plate 35 is pushed out of the slide groove 36 under the action of the spring, thereby reducing the space of the feed trough 23. At the same time, when the spiral plate 4 moves to the right, the area of ​​the spiral plate 4 located between the discharge baffle 3 and the cover 5 becomes smaller. When the space of the discharge trough 32 and the area of ​​the spiral plate 4 become smaller, the discharge amount of the powder can be reduced.

[0076] By controlling the spiral plate 4 and the discharge baffle 3 to move left or right, the space of the discharge trough 32 and the area of ​​the spiral plate 4 can be adjusted, thereby adjusting the discharge amount of the powder. In this process, the discharge amount of the powder can be adjusted according to the feed amount of the metal raw material, thereby avoiding the influence on the grinding of the metal raw material when there is a large deviation between the feed amount and the discharge amount.

[0077] Furthermore, since the cylinder 56 fixedly connected to the cover 5 seals the feed slot 23 on the right side of the cover 5, the powder in the discharge pipe 22 can be blocked to prevent the powder from leaking out of the feed slot 23 on the right side of the cover 5 when the powder moves to the right side of the cover 5.

[0078] Embodiment three:

[0079] The right end surface of the mounting frame 2 is fixedly connected with an extension tube 25, and the discharge tube 22 is slidably connected with the extension tube 25;

[0080] In this embodiment, slideways 26 are provided on the upper and lower sides of the discharge pipe 22 and on the outer surface of the discharge pipe 22;

[0081] The top and bottom positions of the inner ring of the circular groove 21 are fixedly connected to the limit blocks 27, and the limit blocks 27 slide in the slideway 26 provided on the discharge pipe 22;

[0082] Specifically, since the mounting frame 2 is fixedly connected with the extension tube 25, when the discharge tube 22 moves left and right, the discharge tube 22 will move in the extension tube 25. Since the extension tube 25 is fixed, the discharge position can be guaranteed to be fixed, and the powder material is prevented from being discharged along the discharge tube 22, resulting in an uncertain discharge position.

[0083] Furthermore, since the limit block 27 in the circular groove 21 slides in the slideway 26 opened on the discharge pipe 22, the existence of the limit block 27 can limit the discharge pipe 22 to prevent the discharge pipe 22 from rotating with the swivel 31. At the same time, when the discharge pipe 22 moves left and right, it will slide left and right along the limit block 27.

[0084] Embodiment 4:

[0085] The left end surface of the discharge baffle plate 3 is fixedly connected with a uniformly arranged guide plate 38, and the guide plate 38 and the discharge chute 32 are close to each other;

[0086] In this embodiment, the surface of the guide plate 38 is inclined toward the discharge chute 32;

[0087] Specifically, since the left end face of the baffle is fixedly connected with an evenly arranged baffle, when the metal raw material moves to a certain height following the inner lining plate 14, the powder will fall downward, and part of the powder will fall on the guide plate 38. At the same time, since the surface of the guide plate 38 is inclined toward the side of the discharge chute 32, the powder that falls on the guide plate 38 can pass through the discharge chute 32 more easily, thereby improving the efficiency of discharging materials. If some metal raw materials cannot pass through the discharge chute 32, when the guide plate 38 rotates to the upper side, these parts of the metal raw materials will fall from the guide plate 38.

[0088] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
