Description

Technical Field

[0001] The utility model relates to the technical field of suspension agent production, and particularly relates to a grinding device for the production of oil suspension agents. Background Art

[0002] The grinding device used in the production of oil suspension agents is mainly used to finely grind the solid particles in the oil suspension agent to improve its dispersibility and stability. Usually, ball mills and colloid mills are used as grinding devices.

[0003] Combined with the publication number CN219273256U, the publication date is June 30, 2023, which discloses a grinding device for the production of oil suspension agents, including a housing. A feed hopper is fixedly connected to the top of the housing. A discharge pipe is arranged at the bottom of the housing, and a valve is arranged on the discharge pipe. A sliding sleeve is fixedly connected to the top of the housing, and a transmission shaft is slidably connected to the inner wall of the sliding sleeve. A grinding wheel is fixedly connected to the bottom end of the transmission shaft. A guide rod is fixedly connected to the top of the housing, and a mounting plate is slidably connected to the surface of the guide rod. A first motor is fixedly connected to the surface of the mounting plate. By precisely controlling the rotation angle of the output shaft of the second motor, the cylinder on the rotating rod drives the strip-shaped frame to move up and down, so that the mounting plate drives the grinding wheel at the bottom end of the transmission shaft to rise and fall to a specified position height, adjusting the gap distance between the grinding wheel and the grinding frame, thereby increasing the grinding effect of the grinding wheel on the oil suspension agent.

Specific embodiments

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As Figures 1-5 shown, a grinding device for the production of oil suspending agents includes a frame 1 and comprises:

[0029] A grinding chamber provided on the frame 1, which is divided into an outer sleeve 5 and a centrally rotating cylinder 4 driven to rotate, and a discharge port 6 is provided on the outer sleeve 5;

[0030] A grinding hopper 41 is fixedly provided at the bottom end of the central rotating cylinder 4, and a plurality of filter holes are provided on the grinding hopper 41;

[0031] A drive motor 2 slidably provided on the frame 1, and a grinding hammer 3 extending into the grinding hopper 41 is fixedly provided at the end of its output shaft;

[0032] Wherein, the outer wall of the grinding hopper 41 and the inner wall of the outer sleeve 5 enclose a discharge channel.

[0033] Specifically, the outer sleeve 5 is fixedly arranged on the frame 1, and the grinding hopper 41 rotates relative to the outer sleeve 5. The filter holes on the grinding hopper 41 are all located in the upper part. During grinding, first, manually or by using devices such as electric telescopic rods, the driving motor 2 is moved downward so that the upper end surface of the grinding hammer 3 is offset from the port of the central rotating cylinder 4. The raw materials are poured from the port of the central rotating cylinder 4, so that the raw materials fall on the upper end surface of the grinding hammer 3. With the start of the driving motor 2, the output shaft outputs torque, thereby driving the grinding hammer 3 to rotate, and making the raw materials on the upper end surface shake off and fall into the grinding hopper 41, so as to scatter the raw materials. Then, the driving motor 2 is moved downward again so that the grinding hammer 3 crushes the raw materials. At the same time, the central rotating cylinder 4 can be rotated by driving with a motor or manually, so as to drive the grinding hopper 41 to rotate. The crushed raw materials rotate with the grinding hopper 41, so that the raw materials are affected by the centrifugal force and move away from the center of the grinding hopper 41. Since the side wall of the grinding hopper 41 is an inclined surface, the raw materials move upward along the side wall of the grinding hopper 41 under the action of the centrifugal force, and the raw material particles with smaller particle size and lighter weight first enter the discharge channel through the filter holes, playing a role in screening.

[0034] In the above technology, through the design of the grinding hopper 41, the raw materials move upward along the side wall of the grinding hopper 41 under the action of the centrifugal force, and the raw material particles with smaller particle size and lighter weight first enter the discharge channel through the filter holes, playing a role in screening. While the raw material particles with larger particle size and heavier weight stay at the bottom of the grinding hopper 41 and are crushed and ground by the grinding hammer 3, without the need to cooperate with a lifting device, which is more convenient.

[0035] As a further embodiment provided by the present utility model, a top plate 42 is slidably assembled at the bottom of the grinding hopper 41.

[0036] Specifically, the top plate 42 includes arc-shaped blades arranged in a circumferential array, and the upper end surface of the top plate 42 can be on the same horizontal plane as the inner wall bottom surface of the grinding hopper 41 to avoid affecting the work of the grinding hammer 3. After the raw materials are ground multiple times, they are prone to caking at the bottom of the inner wall of the grinding hopper 41 and forming a thin sheet that adheres to the bottom surface. At this time, the top plate 42 is driven to slide upward, and the caked raw materials are broken by the top plate 42. Then, the grinding hammer 3 continues to grind the broken raw materials, repeating this process multiple times.

[0037] As still another embodiment provided by the present utility model, a transmission rod 7 is slidably arranged on the frame 1, the first end of the transmission rod 7 is fixedly connected to a fixed disk 22, and the top plate 42 is rotatably arranged at the second end of the transmission rod 7.

[0038] Specifically, the transmission rod 7 has a C-shaped structure. Since there is a convex block on the output shaft of the driving motor 2 that forms a blocking and separating fit with the fixed disk 22, and the fixed disk 22 is located in the concave part in the middle of the convex block. When the driving motor 2 moves downward to grind the raw materials, it drives the convex block to move downward until it abuts against the upper side of the fixed disk 22, so that the fixed disk 22 moves downward to block the central rotating cylinder 4, preventing dust from scattering. Then, the driving motor 2 is moved upward, and the convex block is moved upward again through the convex block, so that the convex block abuts against the lower side of the fixed disk 22, driving the fixed disk 22 to disengage from the central rotating cylinder 4, which is convenient for the user to observe the grinding situation. At the same time, the top disk 42 is driven to move upward by the transmission rod 7 to break up some of the caked raw materials. Then, the driving motor 2 is continuously moved downward, driving the fixed disk 22 to move downward, so as to drive the top disk 42 to return to the state where the upper end surface of the top disk 42 is flush with the bottom of the inner wall of the grinding hopper 41.

[0039] As yet another embodiment further provided by the present utility model, it further includes a transmission gear set 21 for driving the central rotating cylinder 4, including a sun gear 211 fixedly arranged on the output shaft of the driving motor 2;

[0040] A planetary gear 212 rotatably arranged on the fixed disk 22 and meshing with the sun gear 211;

[0041] An internal gear ring 213 arranged in the port of the central rotating cylinder 4 and meshing with the planetary gear 212.

[0042] Specifically, the driving motor 2 moves downward so that the sun gear 211 moves downward, and the convex block does not contact the fixed disk 22 and meshes with the planetary gear 212. When moving downward continuously, the convex block pushes the entire fixed disk 22 downward until the upper end surface of the top disk 42 is flush with the bottom of the inner wall of the grinding hopper 41. Then, the output shaft of the driving motor 2 outputs torque, driving the sun gear 211 to rotate. The meshing planetary gear 212 is driven to rotate by the sun gear 211, and the internal gear ring 213 is driven to rotate by the planetary gear 212, so that the central rotating cylinder 4 rotates, and the rotating direction of the central rotating cylinder 4 is opposite to that of the grinding hammer 3, making the speed of the grinding hammer 3 relative to the raw materials faster.

[0043] As yet another embodiment further provided by the present utility model, a fan 62 is rotatably arranged on the discharge port 6, and the fan 62 is driven by the rotation of the central rotating cylinder 4.

[0044] Specifically, a runner 61 is rotatably arranged in the discharge port 6, and there is a rectangular opening in the discharge port 6, so that the side surface of the runner 61 extends out of the discharge port 6 through the rectangular opening, and the runner 61 abuts against the outer wall of the central rotating cylinder 4. When the central rotating cylinder 4 rotates, it drives the runner 61 to rotate, and then drives the fan 62 to rotate through a transmission belt. The fan 62 dissipates heat from the discharge port 6 to prevent the heat of the raw materials after grinding from being too high.

[0045] Working principle: During grinding, first manually or using a device such as an electric telescopic rod to move the drive motor 2 downward, so that the upper end surface of the grinding hammer 3 is offset from the port of the central rotating cylinder 4. Pour the raw materials from the port of the central rotating cylinder 4, and drive the sun gear 211 to move downward. And the convex block does not contact the fixed disk 22 and meshes with the planetary gear 212. When continuing to move downward, the convex block pushes the entire fixed disk 22 downward, so that the fixed disk 22 moves downward to block the central rotating cylinder 4, avoiding the scattering of dust until the upper end surface of the top disk 42 is flush with the bottom of the inner wall of the grinding hopper 41. Subsequently, the output shaft of the drive motor 2 outputs torque, thereby driving the sun gear 211 to rotate. The meshing planetary gear 212 is driven to rotate by the sun gear 211, and then the internal gear ring 213 is driven to rotate by the planetary gear 212, so that the central rotating cylinder 4 rotates, thereby driving the grinding hopper 41 to rotate. The crushed raw materials rotate with the grinding hopper 41, so that the raw materials are affected by the centrifugal force and move away from the center of the grinding hopper 41. Since the side wall of the grinding hopper 41 is inclined, the raw materials move upward along the side wall of the grinding hopper 41 under the action of the centrifugal force, and the raw material particles with smaller particle size and lighter weight first enter the discharge channel through the filter holes, playing a role in screening. When the central rotating cylinder 4 rotates, it drives the runner 61 to rotate, thereby driving the fan 62 to rotate through the transmission belt. The fan 62 dissipates heat from the discharge port 6 to avoid the large heat of the raw materials after grinding; after the raw materials are ground multiple times, they are prone to caking at the bottom of the inner wall of the grinding hopper 41 and form a thin sheet that fits the bottom surface. Move the drive motor 2 upward. The convex block on the output shaft moves upward, so that the convex block abuts against the lower side of the fixed disk 22, driving the fixed disk 22 to disengage from the central rotating cylinder 4, which is convenient for the user to observe the grinding situation. At the same time, the top disk 42 is driven to move upward through the transmission rod 7 to break some of the caked raw materials.

[0046] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
