Description

Technical Field

[0001] This invention relates to the field of calcium carbonate production, specifically to a ball milling system for calcium carbonate production. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics production for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials and are widely used in mineral processing, building materials, and chemical industries. They can be divided into dry and wet grinding methods. Based on the discharge method, they can be divided into grate type and overflow type.

[0003] An existing patent (publication number: CN113182025A) discloses a ball mill for calcium carbonate production, including an outer frame. A motor is fixedly connected to the lower surface of the outer frame. A shaft is fixedly connected to the left end of the output shaft of the motor.

The side of the toothed plate is inclined, and a wedge-shaped frame that abuts against the side of the toothed plate is provided laterally on the outer wall of the bearing platform.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In this invention, a steel ball is placed in the sleeve, and a certain amount of calcium carbonate is added into the sleeve. Then, a drive motor drives the worm gear to rotate, which in turn drives the turbine to rotate, causing the sleeve to rotate on the end cover. The steel ball placed in the sleeve comes into contact with the calcium carbonate, so that the steel ball can effectively perform ball milling with the calcium carbonate, grinding the calcium carbonate into a fine powder.

[0013] In this invention, after the ball milling of calcium carbonate in the sleeve is completed by the continuous rotation of the sleeve, the operator rotates the adjustment handle, which rotates the support base 90 degrees, changing the sleeve from a horizontal to a vertical position. At this time, as the support base rotates, the rotating gear on the support base will contact the cylindrical gear, thereby driving the rotating gear to rotate. The rotation of the rotating gear causes the rotating rod to rotate, which in turn drives the first rotating disk to rotate. The first rotating disk drives the second rotating disk to rotate via a belt. The second rotating disk controls the valve to open, allowing water in the water tank to flow into the connecting pipe. One end of the connecting pipe is connected to the end cap, allowing the water in the water tank to flow towards the inside of the sleeve. At this time, the calcium carbonate contained in the sleeve will be flushed downward by the water, thus allowing the ball-milled calcium carbonate to be discharged outward under the action of the water, achieving the calcium carbonate discharge operation.

[0014] In this invention, when water flows from the water tank into the connecting pipe, a small portion of the water enters the storage tank through a branch pipe connected to the connecting pipe, resulting in a small amount of water in the storage tank. After calcium carbonate is discharged from the sleeve, the operator rotates the adjusting handle to make the support seat move the sleeve vertically upwards. At this time, the rotating gear rotates, causing the rotating rod to rotate. The rotation of the rotating rod causes the rotating frame to deflect and contact the abutment at the end of the moving rod. The moving rod then moves downwards, squeezing the water in the storage tank towards the outlet pipe through the sieve plate. At this time, the hydraulic check valve at the outlet pipe opens under pressure, allowing the water in the storage tank to flow into the sleeve through the outlet pipe. When the required calcium carbonate is added into the sleeve for ball milling, the calcium carbonate can come into contact with and fuse with a small amount of water during ball milling, resulting in better ball milling effect and improved processing efficiency. The storage tank has a low water storage capacity, only able to store a small amount of water for calcium carbonate ball milling.

[0015] In this invention, when the support base drives the sleeve to be vertically upward, the rotation of the sleeve will cause the outer sleeve cover to move. The movement of the outer sleeve cover will cause the support frame to move. At this time, the pulleys set on the support frame will move within the limiting slide table around the rotating rod as the center. The pulleys will then contact the protruding end of the limiting slide table. Driven by the limiting slide table, the pulleys will cause the positioning frame to move. The wedge-shaped block set on the moving positioning frame will contact the wedge-shaped end on the positioning rod, thereby causing the positioning rod to move. The positioning rod will then cause the adjusting plate to slide on the support frame. When the adjusting plate slides, two sets of... The slot will cause the rotating shaft and the adjusting frame on the sleeve to deflect, thereby opening the two sets of half-blades on the outer cylinder cover. At this time, the operator can put the calcium carbonate to be ball-milled into the sleeve to continue the ball milling operation. When the calcium carbonate ball milling is completed, when the sleeve is set vertically downward, the calcium carbonate and water can flow out from the filter holes through the two sets of half-blades to achieve the discharge. By using this setting to ball mill calcium carbonate, the operation of ball milling with water can be effectively solved, thus improving the working efficiency of calcium carbonate ball milling.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 7 The present invention provides a technical solution: a ball milling system for calcium carbonate production, including a vertically erected support platform 1, a rotating rod 11 rotatably mounted on the support platform 1, an adjusting handle 12 at one end of the rotating rod 11, and a support base 13 connected to the other end of the rotating rod 11, and a ball milling device 2 for ball milling calcium carbonate mounted on the support base 13.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the ball milling device 2 includes a drive motor 21 fixedly mounted on the outer wall of the support base 13. The main shaft of the drive motor 21 is connected to a worm gear 22. An end cover 23 is fixedly mounted on the support base 13. A sleeve 24 is rotatably mounted on the end cover 23 on the support base 13. Several steel balls are mounted in the sleeve 24. A turbine 25 that meshes with the worm gear 22 is fixedly mounted on the outer wall of the sleeve 24.

[0027] A steel ball is installed in the sleeve 24. A certain amount of calcium carbonate is added into the sleeve 24. Then, the drive motor 21 drives the worm gear 22 to rotate. The worm gear 22 drives the turbine 25 to rotate, which in turn makes the sleeve 24 rotate on the end cover 23. The steel ball installed in the sleeve 24 comes into contact with the calcium carbonate, so that the steel ball can effectively perform ball milling operation with the calcium carbonate, grinding the calcium carbonate into a fine powder.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cylindrical gear 3 is fixedly installed on the outer wall of the support platform 1, a rotating rod 31 is rotatably installed on the support base 13, a rotating gear 32 that meshes with the cylindrical gear 3 is installed on the rotating rod 31, a first rotating disk 33 is fixedly installed on the rotating rod 31, a water tank 34 is fixedly installed on the support base 13, a valve 36 is installed at the bottom of the water tank 34, a connecting pipe 35 is provided at the bottom of the valve 36 and the connecting pipe 35 is connected to the end cap 23, a second rotating disk 37 is sleeved on the valve 36, and a belt 38 is sleeved between the first rotating disk 33 and the second rotating disk 37.

[0029] After the ball milling of calcium carbonate in the sleeve 24 is completed by the continuous rotation of the sleeve 24, the operator rotates the adjusting handle 12. The rotating handle 12 rotates the support base 13 by 90 degrees, changing the sleeve 24 from a horizontal to a vertical position. At this time, as the support base 13 rotates, the rotating gear 32 on the support base 13 will come into contact with the cylindrical gear 3, thereby driving the rotating gear 32 to rotate. The rotation of the rotating gear 32 causes the rotating rod 11 to rotate, which in turn drives the first rotating disk 33 to rotate. The first rotating disk 33 causes the second rotating disk 37 to rotate through the belt 38. The second rotating disk 37 controls the valve 36 to open, allowing water in the water tank 34 to flow into the connecting pipe 35. One end of the connecting pipe 35 is connected to the end cap 23, allowing the water in the water tank 34 to flow towards the sleeve 24. At this time, the calcium carbonate contained in the sleeve 24 will be flushed downward by the water, thus allowing the ball-milled calcium carbonate to be discharged outward under the action of the water, realizing the calcium carbonate discharge operation.

[0030] In this embodiment, as Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, the top of the support base 13 is also provided with a storage tank 4. A moving rod 41 is slidably arranged inside the storage tank 4. A sieve plate is provided at the part of the moving rod 41 located inside the storage tank 4. A stop block 43 is provided at the top of the moving rod 41. A pressure spring 44 is also sleeved on the moving rod 41. The two ends of the pressure spring 44 are respectively connected to the stop block 43 and the storage tank 4. A branch pipe 45 is provided between the storage tank 4 and the connecting pipe 35. A water outlet pipe 46 is also connected between the storage tank 4 and the end cover 23. A rotating frame 47 is also fixedly arranged on the rotating rod 31. The end of the rotating frame 47 is wedge-shaped and contacts the stop block 43 at the bottom of the moving rod 41. A hydraulic one-way valve is provided at the water outlet pipe 46.

[0031] When water flows from water tank 34 into connecting pipe 35, a small portion of the water will enter storage tank 4 through branch pipe 45 connected to connecting pipe 35, leaving storage tank 4 with a small amount of water. After calcium carbonate is discharged from sleeve 24, the operator rotates adjusting handle 12, causing support base 13 to move sleeve 24 vertically upwards. At this time, rotating gear 32 rotates, causing rotating rod 31 to rotate. Rotating rod 31 will cause rotating frame 47 to deflect, making it contact the abutment 43 at the end of moving rod 41. Rod 41 will move downwards, and the downward movement of rod 41 will squeeze the water in storage tank 4 towards outlet pipe 46 through the screen plate. At this time, the hydraulic check valve at outlet pipe 46 will be opened by force, allowing the water in storage tank 4 to flow into sleeve 24 through outlet pipe 46. When the required calcium carbonate is added into sleeve 24 for ball milling, the calcium carbonate can come into contact with a small amount of water and blend during ball milling, making the ball milling effect better and improving the processing efficiency of calcium carbonate ball milling. The storage capacity of storage tank 4 is low and can only store a small amount of water for calcium carbonate ball milling.

[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the other end of the sleeve 24 is also fitted with an outer sleeve cover 5. The outer sleeve cover 5 is rotatably fitted with the sleeve 24. A support frame 51 is fixedly installed on the outer wall of the outer sleeve cover 5. An adjusting plate 52 is slidably installed on the support frame 51. Two sets of oppositely arranged slots 53 are opened on the adjusting plate 52. A rotating shaft 54 ​​is rotatably installed on the outer sleeve cover 5. A sleeve shaft 55 is rotatably installed on the rotating shaft 54. Half-fan blades 56 are provided on both the rotating shaft 54 ​​and the sleeve shaft 55. Filter holes 57 are opened in the center of both sets of half-fan blades 56. The two sets of half-fan blades 56 cover the outer sleeve cover 5. Adjusting frames 6 are fixedly connected to both the rotating shaft 54 ​​and the sleeve shaft 55. One end of each set of adjusting frames 6 contacts the slot 53 on the adjusting plate 52.

[0033] A positioning rod 61 is fixedly installed on the outer wall of the adjusting plate 52. A return spring 62 is sleeved on the positioning rod 61. The two ends of the return spring 62 are respectively connected to the adjusting plate 52 and the support frame 51. The end of the positioning rod 61 is wedge-shaped. A limiting slide 63 is fixedly installed on the outer wall of the bearing platform 1. A limiting groove 64 is provided on the inner wall of the limiting slide 63. The limiting slide 63 is inclined and has a protruding end. A positioning frame 65 is slidably installed on the support frame 51. A pulley 66 is provided on the positioning frame 65. The pulley 66 is located in the limiting groove 64 of the limiting slide 63 and is in contact with the limiting slide 63. A compression spring is provided between the positioning frame 65 and the support frame 51. A wedge block 67 is provided on the outer wall of the positioning frame 65 and is in contact with the wedge end of the positioning rod 61.

[0034] When the support base 13 drives the sleeve 24 to be vertically upward, the rotation of the sleeve 24 will cause the outer sleeve cover 5 to move. The movement of the outer sleeve cover 5 will cause the support frame 51 to move. At this time, the pulley 66 set on the support frame 51 will move within the limiting slide 63 around the rotating rod 11. The pulley 66 will then contact the protruding end of the limiting slide 63. Driven by the limiting slide 63, the pulley 66 will drive the positioning frame 65 to move. The wedge block 67 set on the moving positioning frame 65 will then contact the wedge end on the positioning rod 61, thereby driving the positioning rod 61 to move. The positioning rod 61 will then drive the adjusting plate 52 to slide on the support frame 51. When the section plate 52 slides, the two sets of slots 53 will drive the rotating shaft 54 ​​and the adjusting frame 6 on the sleeve to deflect, thereby opening the two sets of half-fan blades 56 on the outer cylinder cover 5. At this time, the operator can put the calcium carbonate to be ball-milled into the sleeve 24 to continue the ball milling operation. When the calcium carbonate ball milling is completed, when the sleeve 24 is set vertically downward, the calcium carbonate and water can flow out from the filter holes 57 through the two sets of half-fan blades 56 to achieve its discharge. By using this setting to ball mill calcium carbonate, the operation of ball milling with water can be effectively solved, and the working efficiency of calcium carbonate ball milling can be improved.

[0035] In this embodiment, as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the outer wall of the limiting slide 63 is also provided with an outer ring gear 7, and the support frame 51 is also fixedly provided with a positioning plate 71. The positioning plate 71 is provided with a rotatably arranged limiting gear 72, which meshes with the outer ring gear 7. The positioning plate 71 is also provided with a slidably arranged limiting rod 73, and a toothed plate 74 that contacts the limiting gear 72 is fixedly arranged on the limiting rod 73. A tension spring 75 is also provided between the limiting rod 73 and the positioning plate 71. The side of the toothed plate 74 is inclined. The outer wall of the bearing platform 1 is laterally provided with a wedge-shaped frame 76 that abuts against the side of the toothed plate 74.

[0036] When the support frame 51 drives the sleeve 24 to rotate normally, the limiting gear 72 will contact the outer ring gear 7 to make the support frame 51 move stably. When the sleeve 24 rotates to a horizontal position, the wedge frame 76 will contact the side of the toothed plate 74, thereby driving the limiting rod 73 to move the toothed plate 74. The toothed plate 74 contacts the limiting gear 72 and locks it, so that the sleeve 24 can rotate stably to maintain the stability of the ball mill when it rotates to ball mill calcium carbonate.

[0037] The method of use and advantages of this invention: The working process of the ball milling system for calcium carbonate production is as follows:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown: A steel ball is provided in the sleeve 24. A certain amount of calcium carbonate is put into the sleeve 24. Then, the drive motor 21 drives the worm 22 to rotate. The worm 22 drives the turbine 25 to rotate, which in turn makes the sleeve 24 rotate on the end cover 23. The steel ball provided in the sleeve 24 comes into contact with the calcium carbonate, so that the steel ball can effectively ball mill the calcium carbonate and grind it into a fine powder.

[0039] After the ball milling of calcium carbonate in the sleeve 24 is completed by the continuous rotation of the sleeve 24, the operator rotates the adjustment handle 12. The rotation of the adjustment handle 12 causes the support base 13 to rotate 90 degrees, so that the sleeve 24 changes from a horizontal state to a vertical state. At this time, as the support base 13 rotates, the rotating gear 32 on the support base 13 will contact the cylindrical gear 3, thereby driving the rotating gear 32 to rotate. The rotation of the rotating gear 32 causes the rotating rod 11 to rotate. The rotation of the rotating rod 11 drives the first rotating disk 33 to rotate. The first rotating disk 33 causes the second rotating disk 37 to rotate through the belt 38. The second rotating disk 37 controls the valve 36 to open, so that the water in the water tank 34 can flow into the connecting pipe 35. One end of the connecting pipe 35 is connected to the end cap 23, so that the water in the water tank 34 can flow towards the sleeve 24. At this time, the calcium carbonate contained in the sleeve 24 will be flushed downward by the water, so that the calcium carbonate after ball milling can be discharged outward by the water, realizing the calcium carbonate discharge operation.

[0040] When water flows from water tank 34 into connecting pipe 35, a small portion of the water will enter storage tank 4 through branch pipe 45 connected to connecting pipe 35, leaving storage tank 4 with a small amount of water. After calcium carbonate is discharged from sleeve 24, the operator rotates adjusting handle 12, causing support base 13 to move sleeve 24 vertically upwards. At this time, rotating gear 32 rotates, causing rotating rod 31 to rotate. Rotating rod 31 will cause rotating frame 47 to deflect, making it contact the abutment 43 at the end of moving rod 41. Rod 41 will move downwards. As rod 41 moves downwards, it squeezes the water in storage tank 4 towards outlet pipe 46 through the screen. At this time, the hydraulic check valve at outlet pipe 46 is opened by force, allowing the water in storage tank 4 to flow into sleeve 24 through outlet pipe 46. When the required calcium carbonate is added into sleeve 24 for ball milling, the calcium carbonate can come into contact with a small amount of water and blend during ball milling, making the ball milling effect better and improving the processing efficiency of calcium carbonate ball milling. Storage tank 4 has a low water storage capacity and can only store a small amount of water for calcium carbonate ball milling.

[0041] When the support base 13 drives the sleeve 24 to be vertically upward, the rotation of the sleeve 24 will cause the outer sleeve cover 5 to move. The movement of the outer sleeve cover 5 will cause the support frame 51 to move. At this time, the pulley 66 set on the support frame 51 will move within the limiting slide 63 around the rotating rod 11. The pulley 66 will then contact the protruding end of the limiting slide 63. Driven by the limiting slide 63, the pulley 66 will drive the positioning frame 65 to move. The wedge block 67 set on the moving positioning frame 65 will then contact the wedge end on the positioning rod 61, thereby driving the positioning rod 61 to move. The positioning rod 61 will then drive the adjusting plate 52 to slide on the support frame 51. When the section plate 52 slides, the two sets of slots 53 will drive the rotating shaft 54 ​​and the adjusting frame 6 on the sleeve to deflect, thereby opening the two sets of half-fan blades 56 on the outer cylinder cover 5. At this time, the operator can put the calcium carbonate to be ball-milled into the sleeve 24 to continue the ball milling operation. When the calcium carbonate ball milling is completed, when the sleeve 24 is set vertically downward, the calcium carbonate and water can flow out from the filter holes 57 through the two sets of half-fan blades 56 to achieve its discharge. By using this setting to ball mill calcium carbonate, the operation of ball milling with water can be effectively solved, and the working efficiency of calcium carbonate ball milling can be improved.

[0042] When the support frame 51 drives the sleeve 24 to rotate normally, the limiting gear 72 will contact the outer ring gear 7 to make the support frame 51 move stably. When the sleeve 24 rotates to a horizontal position, the wedge frame 76 will contact the side of the toothed plate 74, thereby driving the limiting rod 73 to move the toothed plate 74. The toothed plate 74 contacts the limiting gear 72 and locks it, so that the sleeve 24 can rotate stably to maintain the stability of the ball mill when it rotates to ball mill calcium carbonate.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
