Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, specifically to a spherical granulator for producing calcium magnesium nitrate. Background Technology

[0002] Calcium magnesium nitrate is a white granular substance with good water solubility, making it widely used in agriculture as a highly efficient calcium and magnesium fertilizer. This fertilizer is characterized by its rapid effect and good absorption, quickly replenishing the calcium and magnesium elements needed by crops, thereby improving crop yield and quality. Granulation machines are required in the production process of calcium magnesium nitrate.

[0003] For example, a spherical granulator for producing calcium magnesium nitrate, as described in announcement number "CN213791509U," uses an extrusion disc to force the calcium magnesium nitrate raw material from the extrusion chamber through extrusion holes. Simultaneously, a drive motor moves a pelletizing blade to cut the extruded material into small particles. This integrated granulation and drying process offers high granulation efficiency and produces relatively dry particles that are easy to store. However, after the calcium magnesium nitrate is cut into small particles, it generates residue due to collisions with the pipes during transport. This device directly collects the calcium magnesium nitrate after it has been formed, resulting in the collection of residue along with the granules. This necessitates further screening by workers to remove the residue, reducing the device's efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of requiring workers to screen the collected calcium magnesium nitrate again to remove residues, which reduces the working efficiency of the equipment. Therefore, a spherical granulator for producing calcium magnesium nitrate is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a spherical granulator for producing calcium magnesium nitrate, comprising a first bending plate and an extrusion box. The bending plate is fixedly connected to the outer wall of the extrusion box. A box body is fixedly connected to the inner wall of the first bending plate via a bracket. An opening structure is provided at the bottom of the box body. A vibration structure is provided inside the box body. A second bending plate is fixedly connected to the upper end of the extrusion box. A first hydraulic cylinder is fixedly connected to the end of the second bending plate. A pressure plate is fixedly connected to the output end of the first hydraulic cylinder. The outer wall of the pressure plate is slidably connected to the extrusion box.

[0007] Preferably, the opening structure includes a vertical plate, the upper end of which is fixedly connected to the box body, a first block fixedly connected to the right end of the vertical plate, the right end of which is movably connected to a second hydraulic cylinder via a pin, a second block fixedly connected to the output end of the second hydraulic cylinder, the second block being movably connected to a third block via a pin, and a bottom plate fixedly connected to the upper end of the third block, the bottom plate being movably connected to the box body via a hinge.

[0008] Preferably, the vibration structure includes a housing, which is fixedly connected to the inner wall of the housing via a bracket. A second motor is fixedly connected to one end of the housing, and a cam is fixedly connected to the output end of the second motor. Both ends of the cam are rotatably connected to the housing via bearings. The housing is movably connected to a straight rod via a pin. The middle part of the straight rod is movably connected to a connecting rod via a pin. The end of the connecting rod is movably connected to an impact rod via a pin. A baffle is fixedly connected to the outer wall of the impact rod. The outer wall of the impact rod is slidably connected to the housing. A second spring is sleeved on the outer wall of the impact rod, and both ends of the second spring are fixedly connected to the housing and the baffle, respectively.

[0009] Preferably, the right end of the extrusion box is fixedly connected to the feed inlet, and a pressure plate is fixedly connected to the inner wall of the extrusion box.

[0010] Preferably, a first motor is fixedly connected to the inner wall of the extrusion box via a bracket, the output shaft of the first motor is rotatably connected to the pressure plate via a bearing, and a scraper is fixedly connected to the outer wall of the output shaft of the first motor.

[0011] Preferably, the lower end of the extrusion box is fixedly connected to the box body, the inner wall of the box body is fixedly connected to a first spring, and the upper end of the first spring is fixedly connected to a sieve plate.

[0012] Preferably, a limiting rod is fixedly connected to the lower end of the sieve plate, the outer wall of the limiting rod is slidably connected to the limiting plate, and the end of the limiting plate is fixedly connected to the box body.

[0013] This utility model proposes a spherical granulator for producing calcium magnesium nitrate. The advantages are as follows: Through the cooperation of the vibration structure and the opening structure, the second motor drives the cam to rotate. When the cam rotates to contact the straight rod, it continues to rotate, causing the right end of the straight rod to move downwards. The straight rod's movement drives the connecting rod to move, which in turn drives the impact rod to move. The impact rod's movement causes the baffle to move and stretches the second spring. When the cam is no longer in contact with the straight rod, the elastic force of the second spring drives the impact rod to move upwards, causing it to strike the screen plate, thus vibrating the screen plate and granulating the calcium magnesium nitrate. As calcium magnesium nitrate is conveyed to the left, calcium magnesium nitrate residue falls into the interior of the tank. The output end of the second hydraulic cylinder shortens, causing the second block to move. The movement of the second block causes the third block to move, which in turn causes the base plate to rotate around the left end. Then, the calcium magnesium nitrate residue inside the tank falls into the collection box due to gravity. The calcium magnesium nitrate residue can be reused. After the calcium magnesium nitrate is granulated, the calcium magnesium nitrate residue can be filtered, and the granulated calcium magnesium nitrate can be collected. This eliminates the need for workers to screen the calcium magnesium nitrate mixed with residue, thus improving the efficiency of the device. Attached Figure Description

The movement of the impact rod 406 stretches the second spring 408. The two ends of the second spring 408 are fixedly connected to the outer shell 401 and the baffle 407 respectively.

[0032] Working principle:

[0033] First, calcium magnesium nitrate is fed into the extrusion chamber 5 through the feed inlet 9 to prepare for the granulation of calcium magnesium nitrate.

[0034] First, connect the external power supply to the first motor 11 and start the first motor 11 to drive the scraper 12 to rotate. Then, start the first hydraulic cylinder 7. The output end of the first hydraulic cylinder 7 extends and drives the pressure plate 8 to move downward, so that the pressure plate 8 cooperates with the pressure plate 10. The calcium magnesium nitrate inside the extrusion box 5 is squeezed downward from the hole of the pressure plate 10. The scraper 12 divides the squeezed calcium magnesium nitrate into small particles. The squeezed calcium magnesium nitrate falls into the inside of the screen plate 13 through the feed port below the extrusion box 5.

[0035] Screening process:

[0036] When the external power supply of the second motor 402 is connected, the second motor 402 is started and drives the cam 403 to rotate. When the cam 403 rotates to contact the straight rod 404, the cam 403 continues to rotate and drives the right end of the straight rod 404 to move downward. The movement of the straight rod 404 drives the connecting rod 405 to move. The movement of the connecting rod 405 drives the impact rod 406 to move. The movement of the impact rod 406 drives the baffle 407 to move and stretches the second spring 408. When the cam 403 is no longer in contact with the straight rod 404, the elastic force of the second spring 408 drives the impact rod 406 to move upward, so that the impact rod 406 strikes the screen plate 13 (the end of the impact rod 406 is made of rubber), causing the screen plate 13 to vibrate. While conveying calcium magnesium nitrate to the left, the calcium magnesium nitrate residue falls into the interior of the box 3. The granular calcium magnesium nitrate is discharged from the left side of the box 3 and collected.

[0037] Residue collection work:

[0038] After the calcium magnesium nitrate granulation is completed, the staff places the collection box under the box 3, and then starts the second hydraulic cylinder 203. The output end of the second hydraulic cylinder 203 shortens, which drives the second block 204 to move. The movement of the second block 204 drives the third block 205 to move. The movement of the third block 205 drives the bottom plate 206 to rotate around the left end. Then, the calcium magnesium nitrate residue inside the box 3 falls into the collection box due to gravity, and the calcium magnesium nitrate residue can be reused.

[0039] After all the raw material inside the extrusion box 5 is extruded, the output end of the first hydraulic cylinder 7 is shortened, which drives the pressure plate 8 to move above the feed inlet 9, so that calcium magnesium nitrate raw material can be added into the extrusion box 5 again.

[0040] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
