Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate processing equipment, in particular to a calcium carbonate processing grinding device. Background Art

[0002] Calcium carbonate is an inorganic compound, commonly known as graystone, limestone, stone powder, marble, etc.; calcium carbonate is neutral, basically insoluble in water, and soluble in hydrochloric acid; it is one of the most common substances on Earth. Calcium carbonate is also an important building material and has a wide range of industrial uses. The processing and use of calcium carbonate often requires grinding.

[0003] The working principle of calcium carbonate processing and grinding equipment usually relies on forces such as rotation, extrusion, impact, and friction. However, traditional processing and grinding is relatively simple. Calcium carbonate is squeezed into powder by rollers. During the process of being ground into powder, calcium carbonate sticks together. The calcium carbonate in the sticky state will become tighter when being crushed by the rollers, resulting in the calcium carbonate not being able to be fully ground into a powder state.

[0012] Furthermore, the outer surface of the rotating shaft is fixedly connected to the bevel gear 1, and the left and right sides of the bevel gear 1 are meshed with the bevel gear 2, and the sides of the two bevel gears 2 away from each other are fixedly connected to the connecting shaft, and the sides of the two connecting shafts away from each other are rotatably connected to the inner wall of the processing barrel, and the outer surfaces of the two connecting shafts are fixedly connected to the inner wall of the roller.

[0014] The utility model has the following beneficial effects:

[0015] (1) The present invention arranges a grinding assembly in a processing barrel, and a plurality of racks are arranged on the surface of the roller. The rotating shaft drives the filter disc to rotate, thereby driving the calcium carbonate on the surface of the filter disc to rotate. During the rotation of the roller, the rack contacts the calcium carbonate and squeezes and grinds it. A plurality of arc-shaped blocks are arranged around the inner wall of the filter disc. As the filter disc rotates, when the arc-shaped block contacts the rack, the rack is pushed, and the spring is squeezed to generate an opposite elastic force. When the arc-shaped block moves away from the rack, the elastic force generated by the spring pushes the rack to reset. The rack moves continuously in this way, and a lateral friction force is generated when the rack contacts the calcium carbonate, thereby improving the grinding effect of the calcium carbonate.

[0016] (2) The utility model provides a plurality of protrusions on the surface of the filter disc. When the protrusions rotate with the filter disc, the protrusions contact the rack, and the rack is subjected to upward pressure. The push spring 2 is squeezed to generate an opposite elastic force. When the protrusions move away from the rack, the elastic force generated by the spring 2 pushes the rack to reset. The rack is repeatedly vibrated by the force exerted by the protrusions, which not only strengthens the grinding force of calcium carbonate, but also has the effect of cleaning the calcium carbonate powder adhering to the surface of the rack.

[0017] (3) The utility model sets a discharge assembly at the bottom of the filter disc. As the connecting ring moves up and down, the flexible membrane is pulled, and the calcium carbonate powder remaining on the surface of the flexible membrane is shaken off to the discharge port at the bottom of the processing barrel, thereby accelerating the collection of the calcium carbonate powder and improving work efficiency.

[0018] (4) The utility model sets a folding tube between the connecting ring and the rotating ring. The folding tube plays a sealing role, preventing the calcium carbonate powder from falling into the outside of the flexible membrane through the gap between them, thereby preventing the calcium carbonate powder from being discharged from the processing barrel. During the up and down movement of the filter plate, the connecting ring is driven to move by the round rod, thereby driving the folding tube to repeatedly expand and contract. The folding tube generates airflow during the expansion and contraction movement. The airflow blows the calcium carbonate powder attached to the surface of the flexible membrane through the air holes opened on the surface of the folding tube, thereby accelerating the discharge of the calcium carbonate powder from the interior of the processing barrel.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The roller 31 is provided with a plurality of placement grooves, and the plurality of placement grooves are arranged in a circular array with the roller 31 as the center. The inner walls of the placement grooves are fixedly connected to springs 237. The side of the spring 237 close to the vertical rod 35 is fixedly connected to the slider 36.

When the protrusion 46 rotates with the filter disc 42, the protrusion 46 contacts the rack 32, and the rack 32 is subjected to upward pressure, pushing the spring 237 to be squeezed to generate an opposite elastic force. When the protrusion 46 moves away from the rack 32, the elastic force generated by the spring 237 pushes the rack 32 to reset. The rack 32 is repeatedly subjected to the force applied by the protrusion 46 to vibrate, which not only strengthens the strength of the calcium carbonate processing and grinding, but also has the effect of cleaning the calcium carbonate powder adhering to the surface of the rack 32.

[0036] A discharge assembly 5 is provided inside the processing barrel 11, and the discharge assembly 5 includes a connecting ring 51, a flexible membrane 52 is fixedly connected to the bottom of the connecting ring 51, a rotating ring 2 53 is fixedly connected to the bottom of the flexible membrane 52, a plurality of round rods 43 are fixedly connected to the bottom of the filter disc 42, the bottoms of the plurality of round rods 43 are fixedly connected to the top of the connecting ring 51, a limiting ring 54 is fixedly connected to the bottom of the connecting ring 51, and a limiting groove is provided at the bottom of the processing barrel 11, and the inner wall of the limiting groove is rotatably connected to the outer surface of the limiting ring 54. By arranging the discharge assembly 5 at the bottom of the filter disc 42, as the connecting ring 51 moves up and down, the flexible membrane 52 is pulled, and the calcium carbonate powder remaining on the surface of the flexible membrane 52 is shaken off to the discharge port at the bottom of the processing barrel 11, thereby accelerating the collection of calcium carbonate powder and improving work efficiency.

[0037] The inner wall of the processing barrel 11 is rotatably connected to a swivel 41, and a number of through holes are opened at the bottom of the swivel 41. The inner walls of the through holes are plugged into the outer surface of the round rod 43. The outer surfaces of the round rods 43 are sleeved with springs 3 44. The tops of the springs 3 44 are fixedly connected to the bottom of the filter disc 42. By setting the round rod 43, the filter disc 42 remains stable during the movement and will not deviate.

[0038] A folding tube 55 is fixedly connected to the bottom of the rotating ring 41, and the bottom of the folding tube 55 is fixedly connected to the top of the connecting ring 51. A plurality of air holes 56 are opened inside the folding tube 55. By arranging the folding tube 55 between the connecting ring 51 and the rotating ring, the folding tube 55 plays a sealing role, preventing the calcium carbonate powder from falling into the outside of the flexible membrane 52 through the gap between them, thereby preventing it from being discharged from the processing barrel 11. The folding tube 55 generates airflow during the telescopic movement, and the airflow blows the calcium carbonate powder attached to the surface of the flexible membrane 52 through the air holes 56 opened on the surface of the folding tube 55, thereby accelerating the discharge of the calcium carbonate powder from the interior of the processing barrel 11.

[0039] The outer surface of the rotating shaft 15 is fixedly connected to a bevel gear 16, and the left and right sides of the bevel gear 16 are meshed with bevel gears 2 17. The two bevel gears 2 17 are fixedly connected to a connecting shaft 18 on the sides away from each other. The two connecting shafts 18 are rotatably connected to the inner wall of the processing barrel 11 on the sides away from each other. The outer surfaces of the two connecting shafts 18 are fixedly connected to the inner wall of the roller 31. The bevel gear 16 rotates, thereby driving the bevel gears 2 17 on both sides that are meshed with the bevel gear 16 to rotate.

[0040] A material discharge assembly 2 is provided on the top of the processing barrel 11, and the material discharge assembly 2 includes a barrel cover 21. The inner wall of the processing barrel 11 is fixedly connected to the outer surface of the barrel cover 21. A feeding port is provided on the surface of the barrel cover 21. A circular hole is provided at the center of the barrel cover 21. The inner wall of the circular hole is rotatably connected to the outer surface of the rotating shaft 15. Two blades 22 are fixedly connected to the outer surface of the rotating shaft 15. A baffle 23 is fixedly connected to the bottom of the barrel cover 21. The bottom of the baffle 23 contacts the outer surface of the rack 32. A base 14 is fixedly connected to the top of the processing barrel 11. A material discharge port is provided at the bottom of the processing barrel 11. The blades 22 move the calcium carbonate accumulated on the barrel cover 21 during rotation, thereby avoiding blockage of the feeding port due to excessive accumulation of calcium carbonate.

[0041] During use, the raw materials of calcium carbonate are placed on the top of the barrel cover 21, and the calcium carbonate enters the interior of the processing barrel 11 through the feeding port opened in the barrel cover 21. A baffle 23 is provided in the barrel to serve as a guide. The calcium carbonate passes through the surface of the baffle 23 and falls onto the top of the filter disc 42. The motor 12 is turned on to drive the rotating shaft 15 to rotate, and the rotating shaft 15 drives the blade 22 to rotate on the surface of the barrel cover 21. During the rotation process, the blade 22 moves the calcium carbonate accumulated on the barrel cover 21, thereby avoiding the blockage of the feeding port due to excessive accumulation of calcium carbonate.

[0042] As the rotating shaft 15 rotates, the bevel gear 16 is driven to rotate, thereby driving the bevel gear 2 17 on both sides that are meshed with the bevel gear 16 to rotate. As the bevel gear 2 17 rotates, the roller 31 set on the surface of the connecting shaft 18 is driven to rotate. The surface of the roller 31 is provided with multiple racks 32. The rotating shaft 15 drives the filter disc 42 to rotate, thereby driving the calcium carbonate on the surface of the filter disc 42 to rotate. During the rotation of the roller 31, the rack 32 contacts with the calcium carbonate, squeezes and grinds it. A number of arc blocks 45 are provided around the inner wall of the filter disc 42. As the filter disc 42 rotates, when the arc block 45 contacts the rack 32, the rack 32 is pushed, and the spring 1 33 is squeezed to generate an opposite elastic force. When the arc block 45 is away from the rack 32, the elastic force generated by the spring 1 33 pushes the rack 32 to reset, and it moves continuously like this. When the rack 32 contacts the calcium carbonate, a lateral friction force is generated, which improves the grinding effect of the calcium carbonate. The surface of the filter disc 42 is provided with several protrusions 46. When the protrusions 46 rotate with the filter disc 42, the protrusions 46 contact the rack 32, and the rack 32 is subjected to upward pressure. The push spring 2 37 is squeezed to produce an opposite elastic force. When the protrusion 46 moves away from the rack 32, the elastic force generated by the spring 2 37 pushes the rack 32 to reset. The rack 32 is repeatedly subjected to the force applied by the protrusions 46 to vibrate, which not only strengthens the processing and grinding force of the calcium carbonate, but also has the effect of cleaning the calcium carbonate powder adhering to the surface of the rack 32. When the rack 32 rotates with the roller 31 to the bottom of the baffle 23 and contacts it, the baffle 23 cleans the calcium carbonate powder remaining on the surface of the rack 32. After cleaning, the rack 32 can maintain high efficiency in grinding calcium carbonate.

[0043] During the rotation of the roller 31, when the rack 32 contacts the filter disc 42, the filter disc 42 is squeezed and moves downward, and the spring three 44 is squeezed to generate an opposite elastic force. When the rack 32 is pressed against the filter disc 42, the elastic force generated by the spring three 44 pushes the filter disc 42 to reset. This repeated movement causes the filter disc 42 to vibrate, and the ground calcium carbonate powder is accelerated to pass through the filter disc 42 and fall onto the surface of the flexible membrane 52. A folded tube 55 is provided between the rotating ring 1 41 and the connecting ring 51 to play a sealing role, preventing the calcium carbonate powder from passing through the gap between them and falling onto the surface of the flexible membrane 52. The outer side of the processing barrel 11 is unable to be discharged. During the up and down movement of the filter disc 42, the connecting ring 51 is driven to move by the round rod 43, thereby driving the folding tube 55 to repeatedly expand and contract. The folding tube 55 generates airflow during the expansion and contraction movement. The airflow blows the calcium carbonate powder attached to the surface of the flexible membrane 52 through the air holes 56 opened on the surface of the folding tube 55, thereby accelerating the discharge of the calcium carbonate powder from the interior of the processing barrel 11. As the connecting ring 51 moves up and down, the flexible membrane 52 is pulled, and the calcium carbonate powder remaining on the surface of the flexible membrane 52 is shaken off to the discharge port at the bottom of the processing barrel 11.
