Description

Technical Field

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

[0002] Calcium carbonate powder has a wide range of uses. For example, it can be used in the laboratory to prevent the destruction of pigments during grinding. In the food field, it can be used as an additive. In the industrial field, calcium carbonate powder can be mixed with water to fully prepare calcium carbonate solution. In order to prepare calcium carbonate powder, ore raw materials such as limestone and marble need to be processed through crushing equipment and grinding equipment.

[0003] At present, the grinding equipment commonly used for calcium carbonate powder is a ball mill. There are many types of ball mills. For example, a Chinese patent with patent publication number CN106694110A discloses a ball mill, which includes a bracket, a barrel and a driving assembly connected to the barrel. The bracket is used to support the barrel. The barrel is a closed hollow cylinder. A large gear ring is arranged at 1 / 2 of the length of the barrel. The large gear ring is a circular ring gear surrounding the barrel. The large gear ring is fixed on the outer wall of the hollow cylinder. The rotating output shaft of the driving assembly is connected to the small gear ring. The large gear ring is meshed with the small gear ring to drive the rotation of the barrel through the rotation of the driving assembly. The driving assembly includes a motor, a coupling, a reducer, and a small gear ring connected in sequence. The output shaft of the motor is connected to the input end of the reducer through the coupling, and the output end of the reducer is connected to the small gear ring, which is then driven to rotate by the motor. The invention arranges the large gear ring in the middle of the cylinder. When the cylinder is driven to rotate, the rotation torque from the large gear ring to both ends of the cylinder is equal, so no resistance torque is formed and the power loss of the motor is minimized.

[0004] When the ball mill provided by the above patent is used to grind and process calcium carbonate powder, the ball mill needs to work for a long time in order to grind the calcium carbonate raw material located inside the ball mill. Then a problem arises. When the particle size of some calcium carbonate powders has met the product requirements, because the ball mill is not provided with a screening structure, the calcium carbonate powder used can only be fully output at one time after stopping the work. This method causes the calcium carbonate powder that meets the size to occupy the space of the ball mill, and affects the impact of the steel ball on other calcium carbonate raw materials, which virtually reduces the production efficiency. If the calcium carbonate powder that meets the requirements can be discharged during the operation of the ball mill, then the calcium carbonate raw material can be appropriately added to the ball mill, and the grinding of more raw materials can be completed within the corresponding time.

DETAILED DESCRIPTION

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments: Example

[0026] like Figure 1 , Figure 4As shown, a raw material grinding device for calcium carbonate processing includes an outer tube 1, a rotating tube 2 and a base. The rotating tube 2 is arranged on the inner side of the outer tube 1, and the outer diameter of the rotating tube 2 is smaller than the inner diameter of the outer tube 1. The base is arranged below the outer tube 1 and can support the outer tube 1 and the rotating tube 2 in an inclined state. A plurality of leak holes are evenly arranged on the side wall of the rotating tube 2, and a steel ball is arranged on the inner side of the rotating tube 2. A motor is arranged on the outer side of the outer tube 1, and the motor can control the rotation of the rotating tube 2. When the device is used to grind calcium carbonate, the calcium carbonate raw material is put into the rotating tube 2, and the rotating tube 2 is controlled by the motor to rotate, driving the calcium carbonate raw material and the steel ball to move irregularly. During the irregular movement of the steel ball and calcium carbonate, the steel ball hits the calcium carbonate to break it and then crush it. When the particle size of the calcium carbonate powder formed after crushing is smaller than the aperture of the leak hole, the calcium carbonate powder will detach from the leak hole and fall into the gap formed by the outer tube 1 and the rotating tube 2. When the outer tube 1 and the rotating tube 2 are tilted, the calcium carbonate powder accumulated in the gap will move and be output. Due to the output of calcium carbonate powder, the material in the rotating tube 2 is reduced, so materials can be added to the rotating tube 2, and the materials originally stored in the rotating tube 2 continue to be crushed by the impact of the steel balls. Therefore, there is no need to wait for all the materials in the rotating tube 2 to be crushed before the calcium carbonate powder can be output. In addition, compared with the existing ball mill, materials can be added to the rotating tube 2 at a corresponding time, which improves the efficiency of calcium carbonate grinding. The device can also be directly or improved to be suitable for grinding other materials.

[0027] like Figure 2 , Figure 3 As shown, in order to stably and flexibly install the rotating tube 2 in the outer tube 1, multiple groups of limiting wheels 12 are arranged on the inner side of the outer tube 1 outside the rotating tube 2, each group of limiting wheels 12 includes two wheel bodies, and an annular plate 21 and an annular rack 23 are respectively arranged at both ends of the outer side of the rotating tube 2, the annular plate 21 can penetrate the wheel body of the same group of limiting wheels 12, and the annular rack 23 is located on the outer side of the limiting wheel 12. Under the cooperation of the annular plate 21 and the limiting wheel 12, the rotating tube 2 is stably placed relative to the outer tube 1, and because the limiting wheel 12 supports the rotating tube 2, the rotating tube 2 can rotate under the action of external force. In addition, a transmission gear 13 is arranged on the side of a certain limiting wheel 12, and the transmission gear 13 is connected to the annular rack 23 and is connected to the output shaft of the motor through a belt. When the motor is working, the transmission gear 13 is driven to rotate, and then the annular rack 23 is controlled to drive the rotating tube 2 to rotate.

[0028] like Figure 2 , Figure 3As shown, in order to fully grind the material in the rotating tube 2, an annular baffle 11 is provided at the upper end of the outer tube 1. The annular baffle 11 is detachably provided on the inner side of the outer tube 1 by bolts. The outer diameter of the annular baffle 11 is equal to the inner diameter of the outer tube 1, and the inner diameter is equal to the outer diameter of the rotating tube 2. Under the action of the annular baffle 11, the upper end of the outer tube 1 is blocked to prevent the material from being discharged from the upper end of the outer tube 1. The lower end of the rotating tube 2 is detachably provided with a sealing disk 22 by bolts, and the upper end is detachably provided with a blocking ring plate 24 by bolts. The outer diameters of the blocking ring plate 24 and the sealing disk 22 are equal to the outer diameter of the rotating tube 2. Under the action of the sealing disk 22, the material is restricted from being discharged, so as to provide support for the grinding of calcium carbonate by impact of the steel balls. Example

[0029] like Figure 1 , Figure 4 As shown, a raw material grinding device for calcium carbonate processing includes an outer tube 1, a rotating tube 2 and a base. The rotating tube 2 is arranged on the inner side of the outer tube 1, and the outer diameter of the rotating tube 2 is smaller than the inner diameter of the outer tube 1. The base is arranged below the outer tube 1 and can support the outer tube 1 and the rotating tube 2 in an inclined state. A plurality of leak holes are evenly arranged on the side wall of the rotating tube 2, and a steel ball is arranged on the inner side of the rotating tube 2. A motor is arranged on the outer side of the outer tube 1, and the motor can control the rotation of the rotating tube 2. When the device is used to grind calcium carbonate, the calcium carbonate raw material is put into the rotating tube 2, and the rotating tube 2 is controlled by the motor to rotate, driving the calcium carbonate raw material and the steel ball to move irregularly. During the irregular movement of the steel ball and calcium carbonate, the steel ball hits the calcium carbonate to break it and then crush it. When the particle size of the calcium carbonate powder formed after crushing is smaller than the aperture of the leak hole, the calcium carbonate powder will detach from the leak hole and fall into the gap formed by the outer tube 1 and the rotating tube 2. When the outer tube 1 and the rotating tube 2 are tilted, the calcium carbonate powder accumulated in the gap will move and be output. Due to the output of calcium carbonate powder, the material in the rotating tube 2 is reduced, so materials can be added to the rotating tube 2, and the materials originally stored in the rotating tube 2 continue to be crushed by the impact of the steel balls. Therefore, there is no need to wait for all the materials in the rotating tube 2 to be crushed before the calcium carbonate powder can be output. In addition, compared with the existing ball mill, materials can be added to the rotating tube 2 at a corresponding time, which improves the efficiency of calcium carbonate grinding. The device can also be directly or improved to be suitable for grinding other materials.

Under the cooperation of the annular plate 21 and the limiting wheel 12, the rotating tube 2 is stably placed relative to the outer tube 1, and because the limiting wheel 12 supports the rotating tube 2, the rotating tube 2 can rotate under the action of external force. In addition, a transmission gear 13 is arranged on the side of a certain limiting wheel 12, and the transmission gear 13 is connected to the annular rack 23 and is connected to the output shaft of the motor through a belt. When the motor is working, the transmission gear 13 is driven to rotate, and then the annular rack 23 is controlled to drive the rotating tube 2 to rotate.

[0031] like Figure 2 , Figure 3 As shown, in order to fully grind the material in the rotating tube 2, an annular baffle 11 is provided at the upper end of the outer tube 1. The annular baffle 11 is detachably provided on the inner side of the outer tube 1 by bolts. The outer diameter of the annular baffle 11 is equal to the inner diameter of the outer tube 1, and the inner diameter is equal to the outer diameter of the rotating tube 2. Under the action of the annular baffle 11, the upper end of the outer tube 1 is blocked to prevent the material from being discharged from the upper end of the outer tube 1. The lower end of the rotating tube 2 is detachably provided with a sealing disk 22 by bolts, and the upper end is detachably provided with a blocking ring plate 24 by bolts. The outer diameters of the blocking ring plate 24 and the sealing disk 22 are equal to the outer diameter of the rotating tube 2. Under the action of the sealing disk 22, the material is restricted from being discharged, so as to provide support for the grinding of calcium carbonate by impact of the steel balls.

[0032] like Figure 5 , Figure 6 As shown, in order to adjust the tilt angle of the outer tube 1 and the rotating tube 2, the base is set as an adjustable base 3, which includes a bottom frame 34 and a support frame 33. A convex plate 35 is set in the middle of the bottom frame 34, and a connecting shaft 37 is set through the top of the convex plate 35. The end of the connecting shaft 37 is inserted into the support frame 33. A telescopic cylinder 36 (which can be set as a cylinder, a hydraulic cylinder, etc.) is hingedly set on the outer side of the bottom frame 34. The telescopic end of the telescopic cylinder 36 is hingedly connected to the end of the support frame 33. Under the operation of the telescopic cylinder 36, the support frame 33 can be controlled to rotate around the connecting shaft 37, thereby adjusting the tilt angle of the support frame 33, and providing support for controlling the outer tube 1 and the rotating tube 2 in a tilted state. Supporting arc plates 32 are set at both ends above the support frame 33, and a clamping arc plate 31 is detachably set above the supporting arc plate 32.
