Description

Technical Field

[0001] The invention relates to the technical field of soil conditioner granulation processing, and in particular to a soil conditioner disc granulation device and a granulation method thereof, which can granulate the soil conditioner with high quality and high efficiency. Background Art

[0002] Oyster shell is a natural mineral rich in calcium carbonate, which is widely used in agriculture, aquaculture and environmental protection. In recent years, with the increasing demand for resource utilization of oyster shells, the application of oyster shell powder as fertilizer and soil conditioner has also gradually increased.

[0003] When oyster shell powder is used as a fertilizer and soil conditioner, it is often necessary to add other raw materials and use corresponding granulation equipment to granulate it. Existing equipment for granulation of soil conditioners mostly adopts disc granulation equipment, which generally includes an inclined granulation disc and a granulation drive motor for driving the granulation disc to rotate. The existing soil conditioner disc granulation equipment has the following defects during use: 1) The material lacks screening action before entering the granulation process, which makes it easy for materials with too large particle size to enter the granulation disc, thereby causing adverse effects on subsequent granulation molding; 2) The granulation effect and granulation efficiency are relatively low, and there is often a problem that the material after granulation is easy to loosen, and the granulation molding efficiency does not meet the design requirements.

[0004] Therefore, the purpose of the present invention is to design a soil conditioner disc granulation equipment and a granulation method that can effectively screen the material before entering the granulation process to ensure that the particle size of the material entering the granulation process meets the granulation requirements; and can effectively improve the structural stability of the material after granulation, and can effectively improve the granulation molding efficiency of the material. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a soil conditioner disc granulation equipment and a granulation method thereof, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A soil conditioner disc granulation device, comprising:

[0008] A frame, on which a corresponding swing seat is swingably mounted, the outer side of the swing seat is swingably mounted on the frame, and the inner side of the swing seat is driven by a corresponding lifting drive mechanism;

[0009] A granulation mechanism, comprising a granulation disc rotatably mounted on the swing seat, wherein the granulation disc is driven by a granulation drive motor mounted on the swing seat;

[0010] The screening mechanism comprises a group of support rods rotatably mounted on the swing seat, a corresponding screening plate is rotatably mounted between the upper ends of the support rods, a plurality of corresponding screening holes are evenly distributed on the bottom side of the screening plate, one end of the screening plate is hingedly connected with a corresponding pulling rod in a downward tilted manner, and the pulling rod is connected to the output shaft end of the corresponding screening drive motor through an eccentric connection;

[0011] The particle size detection mechanism includes a support seat fixedly connected to a swing seat on the outer side of the granulation disc, wherein the support seat is telescopically mounted with a corresponding abutment member through an elastic member, an abutment roller abutting against the granulation disc is rotatably mounted on the inner side of the abutment member, and a corresponding vibration sensor is fixedly connected to the outer side of the abutment member.

[0012] When the vibration detected by the vibration sensor is less than the set value v 1 When the lifting drive mechanism drives the swing seat to swing downward, the inclination angle of the granulating disc is controlled at r 1 .

[0013] When the vibration detected by the vibration sensor is greater than the set value v 2 When the lifting drive mechanism drives the swing seat to swing upward, the inclination angle of the granulating disc is controlled at r 2 .

[0014] When the vibration detected by the vibration sensor is greater than the set value v 3 When the lifting drive mechanism drives the swing seat to further swing upward, the inclination angle of the granulating disc is controlled at r 3 , where v 3 >v 2 >v 1 , r 3 >r 2 >r 1 .

[0015] The granulating disc is connected to a discharge pipe equipped with a discharge valve, and the inclination angle of the granulating disc is r 3 When the material is discharged, the discharge valve opens.

[0016] A corresponding inclination sensor is fixedly connected to the end of the screening plate. When material is added to the screening plate, the screening drive motor drives the pulling rod to adjust the inclination of the screening plate so that the screening plate is in a horizontal state.

[0017] The end of the screening pan that is not connected to the pulling rod is externally connected to a discharge pipe equipped with a discharge valve, and the large-particle material accumulated in the screening pan after screening is discharged through the discharge pipe; when the large-particle material in the screening pan is discharged, the screening drive motor drives the pulling rod to adjust the inclination angle of the screening pan, so that the end of the screening pan equipped with the discharge pipe is tilted downward.

[0018] A group of corresponding mounting seats are fixedly connected to the frame, and fixed shafts rotatably mounted on the mounting seats are fixedly connected to both sides of the swing seat. The swing seat can be swingably mounted on the frame through the cooperation between the fixed shaft and the mounting seat.

[0019] The lifting drive mechanism comprises a column fixedly connected to the frame, and a corresponding telescopic oil cylinder is hingedly connected to a side of the column facing the swing seat and tilted downward, and a piston rod end of the telescopic oil cylinder is hinged to the swing seat.

[0020] A soil conditioner granulation method, based on the above-mentioned disc granulation equipment, comprises the following specific steps:

[0021] S1, adding soil conditioner material to the sieve plate through an external feeding transmission mechanism, starting the sieve drive motor to drive the sieve plate to move back and forth, so as to sieve the material meeting the particle size into the granulation disc;

[0022] S2, the granulation drive motor is started to drive the granulation disc to rotate, so as to granulate the materials that meet the particle size entering the granulation disc;

[0023] S3, the vibration sensor of the particle size detection mechanism detects the vibration amount of the granulation disk in real time, and when the vibration amount detected by the vibration sensor is less than the set value v 1 When the lifting drive mechanism drives the swing seat to swing downward, the inclination angle of the granulating disc is controlled at r 1 To ensure that the material has enough granulation space, thereby improving the granulation rate;

[0024] S4: When the vibration detected by the vibration sensor is greater than the set value v 2 When the lifting drive mechanism drives the swing seat to swing upward, the inclination angle of the granulating disc is controlled at r 2 , in order to increase the rolling kinetic energy of the material after granulation, so as to make the structure of the material after granulation more compact;

[0025] S5: When the vibration detected by the vibration sensor is greater than the set value v 3 When the lifting drive mechanism drives the swing seat to further swing upward, the inclination angle of the granulating disc is controlled at r 3, in order to facilitate the output of the granulated materials.

[0026] Advantages of the present invention:

[0027] 1) The present invention adds a screening mechanism on the basis of the granulation mechanism, which includes a group of rotatable support rods, and then the screening disc is rotatably installed between the upper ends of the support rods, and the eccentric connection between the screening disc and the output shaft end of the screening drive motor is achieved by pulling the rods. During the screening process, it is only necessary to start the screening drive motor to drive the screening disc to form a regular back and forth movement, so as to effectively screen the material entering the screening disc, and directly drop the screened material into the granulation disc, so as to effectively screen the material before entering the granulation process, thereby ensuring that the particle size of the material entering the granulation process meets the granulation requirements.

[0028] 2) The present invention has a swing seat swingably mounted on the frame, and the swingable mounting of the granulation disc is realized by the swing seat, and the molding process is controlled by the intervention of the particle size detection mechanism. Before the material is granulated and molded, the vibration amount caused by the rolling of the material on the granulation disc is small. At this time, the inclination angle of the granulation disc can be controlled within a small range, thereby increasing the rolling contact rate of the material to improve the granulation molding efficiency; and after the granulation molding, the vibration amount caused by the rolling of the material on the granulation disc increases. At this time, the inclination angle of the granulation disc can be increased to increase the rolling kinetic energy of the material after granulation molding, thereby making the structure of the material after granulation molding more compact. This effectively improves the structural stability of the material after granulation, and can effectively improve the granulation molding efficiency of the material.

[0029] 3) As the compactness of the granulated material increases, the vibration caused by its rolling on the granulating disc further increases. At this time, the inclination angle of the granulating disc can be further increased to facilitate the output of the granulated material, thereby effectively ensuring the practical effect of the present invention.

[0030] 4) An inclination sensor is fixedly connected to the end of the screen disc of the present invention. When material is added to the screen disc, the screen driving motor drives the pulling rod to adjust the inclination of the screen disc, so that the screen disc is in a horizontal state, thereby facilitating the loading of materials; and the large-size material accumulated in the screen disc after screening can be discharged through the discharge pipe. When the large-size material in the screen disc is discharged, the screen driving motor drives the pulling rod to adjust the inclination of the screen disc, so that the end of the screen disc provided with the discharge pipe can be tilted downward, thereby facilitating the discharge of the large-size material accumulated in the screen disc after screening, thereby further ensuring the practical effect of the present invention.

[0031] 5) By using the present invention to granulate the soil conditioner, not only the granulation effect and efficiency can be effectively improved, but also the overall granulation process is highly controllable, thereby meeting the requirements for batch granulation of the soil conditioner.

[0042] The particle size detection mechanism 7 includes a support seat 701 fixedly connected to the swing seat 2 on the outside of the granulation disc 401, and the support seat 701 is telescopically installed with a corresponding abutment member 703 through an elastic member 702, and an abutment roller 704 abutting against the granulation disc 401 is rotatably installed on the inner side of the abutment member 703, and a corresponding vibration sensor 705 is fixedly connected to the outer side of the abutment member 703.

[0043] The present invention adds a screening mechanism 5 on the basis of the granulation mechanism 4, which includes a group of rotatable support rods 501, and then a screening disc 502 is rotatably installed between the upper ends of the support rods 501, and the eccentric connection between the screening disc 502 and the output shaft end of the screening drive motor 504 is achieved by pulling the rod 503. During the screening process, it is only necessary to start the screening drive motor 504 to drive the screening disc 502 to form a regular back and forth movement, so as to effectively screen the materials entering the screening disc 502, and directly drop the screened materials into the granulation disc 401, so as to effectively screen the materials before entering the granulation process, thereby ensuring that the particle size of the materials entering the granulation process meets the granulation requirements.

[0044] When the vibration detected by the vibration sensor 705 is less than the set value v 1 When the lifting drive mechanism 3 drives the swing seat 2 to swing downward, the inclination angle of the granulating disc 401 is controlled at r 1 .

[0045] When the vibration detected by the vibration sensor 705 is greater than the set value v 2 When the lifting drive mechanism 3 drives the swing seat 2 to swing upward, the inclination angle of the granulating disc 401 is controlled at r 2 .

When material is added to the screening plate 502, the pulling rod 503 is driven by the screening drive motor 504 to adjust the inclination of the screening plate 502 so that the screening plate 502 is in a horizontal state.

[0051] The end of the screening pan 502 that is not connected to the pulling rod 503 is externally connected to a discharge pipe 10 equipped with a discharge valve 1001. After screening, the large-particle material accumulated in the screening pan 502 is discharged through the discharge pipe 10. When the large-particle material in the screening pan 502 is discharged, the screening drive motor 504 drives the pulling rod 503 to adjust the inclination angle of the screening pan 502, so that the end of the screening pan 502 equipped with the discharge pipe 10 is tilted downward.

[0052] When material is added to the screening plate 502, the screening drive motor 504 drives the pulling rod 503 to adjust the inclination angle of the screening plate 502, so that the screening plate 502 is in a horizontal state, thereby facilitating the loading of materials; and the large-size material accumulated in the screening plate 502 after screening can be discharged through the discharge pipe 10.
