Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer granulation technology, specifically to an anti-caking compound fertilizer high-efficiency granulator. Background Technology

[0002] Compound fertilizer is a chemical fertilizer containing at least two or three nutrients such as nitrogen, phosphorus, and potassium, and is processed through chemical or physical methods. Its main characteristics include high nutrient content, balanced nutrition, few by-products, and good physical properties, which can improve fertilizer utilization and promote high and stable crop yields.

[0003] Utility model patent CN208824433U discloses a novel compound fertilizer extrusion granulator, comprising a storage hopper, a feeder spirally connected to the bottom of the storage hopper, and a stirring shaft rotatably connected to the center of the feeder. A stirring rod is fixedly sleeved at the end of the stirring shaft away from the storage hopper. Two pressure rollers are located below the feeder, and the two pressure rollers are aligned horizontally. A motor is rotatably connected to the rear ends of the two pressure rollers. A granulator housing is located around the pressure rollers, and a baffle is located below the pressure rollers, with a conveyor belt rotatably connected below the baffle. A magnetic block is located on the outer surface of the granulator housing away from the baffle. This novel compound fertilizer extrusion granulator can adjust the feeding speed, prevent pressure roller blockage, improve the uniformity of raw material granules and fertilizer effect, and automatically feed the extruded raw materials into a grading device for grading, collecting them separately for further processing. It is also easy to connect and move.

[0004] Before granulation, compound fertilizers require manual mixing of two or more fertilizers in a mixer according to the specified ratio. The aforementioned new compound fertilizer extrusion granulator cannot meet the mixing requirements before granulation. The mixture needs to be taken out after mixing in the mixer and then manually placed into the storage hopper, which greatly increases the manual operation and is quite cumbersome. Therefore, there is an urgent need for an anti-caking compound fertilizer high-efficiency granulator. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model proposes an anti-caking compound fertilizer high-efficiency granulator to solve the problems mentioned in the background technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A high-efficiency granulator for anti-caking compound fertilizer includes a feeding mechanism, and a granulation mechanism is fixedly connected to the lower left side of the feeding mechanism via a support rod.

[0008] The feeding mechanism includes a feeding cylinder, a first motor is fixedly connected to the right side of the feeding cylinder, a spiral auger is installed inside the feeding cylinder, a discharge pipe is installed at the bottom left side of the feeding cylinder, a first hopper is fixedly installed on the right side of the feeding cylinder, and a stirring assembly is installed above the first hopper.

[0009] The mixing assembly includes a mixing drum, a bracket fixedly connected to the top of the mixing drum, a second motor fixedly connected to the top of the bracket, a rotating hole opened at the top of the bracket, a mixing shaft rotatably connected inside the rotating hole, a scraper fixedly connected to the surface of the mixing shaft, mixing rods fixedly connected to both ends of the mixing shaft, a discharge port provided at the bottom of the mixing drum, an ear plate provided on the left side of the mixing drum, a blocking plate rotatably provided at the bottom of the ear plate, a lever fixedly connected to the right side of the blocking plate, a limit rod fixedly connected to the right side of the mixing drum, a limit groove opened on the front of the limit rod, and a limit piece rotatably connected to the front of the limit rod.

[0010] Preferably, one end of the auger is fixedly connected to the first motor, and the top of the stirring shaft is fixedly connected to the second motor.

[0011] Preferably, there are four scrapers arranged in a circular array.

[0012] Preferably, a first support rod is fixedly connected to the top of the feeding cylinder, and one end of the first support rod is fixedly connected to the mixing cylinder.

[0013] Preferably, the granulation mechanism includes a shell, two support plates are fixedly connected to the top of the shell, two rotating shafts are rotatably connected between the two support plates, a second hopper is fixedly connected to the top of the two support plates, pressure rollers are fixedly connected to the surfaces of the two rotating shafts, the right sides of the two rotating shafts movably pass through the right support plate and extend to its outside, and the right sides of the two rotating shafts are fixedly connected to mutually meshing first gears, and a third motor is fixedly connected to the left side of the left support plate, the output end of the third motor is fixedly connected to one of the rotating shafts.

[0014] Preferably, a fourth motor is fixedly connected to the left side of the housing, and two crushing shafts are rotatably connected inside the housing. The left side of one of the crushing shafts is fixedly connected to the output end of the fourth motor. Multiple crushing rollers are fixedly connected to the surfaces of both crushing shafts. The right sides of both crushing shafts movably penetrate the housing and extend to its outside. Second gears that mesh with each other are fixedly connected to the right sides of the two crushing shafts.

[0015] Preferably, a filter screen is inclinedly arranged inside the housing, a finished product outlet is provided on the left side of the housing, and a waste product outlet is provided on the front of the housing.

[0016] Compared with existing technologies, the beneficial effects of this utility model's high-efficiency granulator for anti-caking compound fertilizer are:

[0017] First, various fertilizers are poured into the mixing drum according to the specified ratio. A second motor drives the mixing shaft to rotate, causing the mixing rod and scraper to rotate. The scraper's rotation prevents the fertilizer from adhering to the inner wall of the mixing drum, while the rotating mixing rod thoroughly mixes the fertilizers. After mixing, a limit plate is rotated, which in turn moves a lever to rotate the plug plate, releasing the limit on the discharge port and allowing the mixed fertilizer to fall in. Once the compound fertilizer is discharged, a first motor drives an auger to rotate, conveying the mixed compound fertilizer to the discharge pipe, where it falls downwards. The granulation mechanism performs subsequent granulation operations. After the fertilizer is discharged from the mixing drum, the plugging plate is rotated to make the lever engage in the limiting groove on the front of the limiting rod. The limiting plate is then moved to limit the limiting rod, causing the plugging plate to block the discharge port. Then, multiple fertilizers are poured into the mixing drum according to the ratio for continuous operation. Thus, when operating, the worker only needs to pour multiple fertilizers into the mixing drum according to the ratio and open and close the plugging plate to complete the mixing and feeding of multiple fertilizers before granulation, which simplifies the operation steps and reduces the labor force of workers.

[0018] Secondly, after the mixed compound fertilizer is discharged downwards from the discharge pipe into the second hopper, a third motor drives one of the rotating shafts to rotate. Since the right sides of the two rotating shafts are fixedly connected to the meshing first gears, the meshing of the first gears drives the other rotating shaft to rotate, causing the pressure roller to rotate. The surface of the pressure roller is provided with forming grooves for compound fertilizer forming. The pressure rollers compress the compound fertilizer into granular blocks through mutual squeezing. The compressed compound fertilizer will be in granular block form. The granular block compound fertilizer falls into the shell. A fourth motor drives one of the crushing shafts to rotate. Since the right sides of the two crushing shafts are fixedly connected to the meshing second gears, the other crushing shaft rotates, which in turn causes the crushing roller to crush the granular block compound fertilizer into granules, realizing granulation. Fine particles and fertilizer residue are filtered out through the filter screen and fall into the waste discharge port for subsequent recycling. The qualified granular compound fertilizer is discharged from the finished product discharge port on the left. The inclined filter screen helps the material to slide naturally under the action of gravity and be screened through the filter screen to prevent agglomeration and improve the quality of granulation.

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] Please refer to the following specific embodiment of an anti-caking compound fertilizer high-efficiency granulator. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a feeding mechanism, and a granulation mechanism is fixedly connected to the lower left side of the feeding mechanism via a support rod;

[0026] The feeding mechanism includes a feeding cylinder 1, a first motor 2 fixedly connected to the right side of the feeding cylinder 1, a spiral auger 3 installed inside the feeding cylinder 1, a discharge pipe 4 installed at the bottom left side of the feeding cylinder 1, a first hopper 5 fixedly installed on the right side of the feeding cylinder 1, and a stirring assembly installed above the first hopper 5.

[0027] The mixing assembly includes a mixing drum 6, a bracket 7 fixedly connected to the top of the mixing drum 6, a second motor 8 fixedly connected to the top of the bracket 7, a rotating hole opened at the top of the bracket 7, a mixing shaft 9 rotatably connected inside the rotating hole, a scraper 10 fixedly connected to the surface of the mixing shaft 9, and mixing rods 11 fixedly connected to both ends of the mixing shaft 9. A discharge port is provided at the bottom of the mixing drum 6, an ear plate is provided on the left side of the mixing drum 6, a blocking plate 12 is rotatably provided at the bottom of the ear plate, a lever 13 is fixedly connected to the right side of the blocking plate 12, a limiting rod 14 is fixedly connected to the right side of the mixing drum 6, a limiting groove is opened on the front of the limiting rod 14, and a limiting piece 15 is rotatably connected to the front of the limiting rod 14.

[0028] Through the above technical solution, when granulating compound fertilizer, various fertilizers are poured into the mixing drum 6 according to the ratio. The second motor 8 drives the mixing shaft 9 to rotate, causing the mixing rod 11 and scraper 10 to rotate. The rotation of the scraper 10 can prevent the fertilizer from adhering to the inner wall of the mixing drum 6. The rotation of the mixing rod 11 fully mixes the fertilizer. After the mixing is completed, the limiting plate 15 is rotated, and the lever 13 drives the blocking plate 12 to rotate, releasing the limit on the discharge port and allowing the mixed fertilizer to fall in. After the compound fertilizer is discharged, the first motor 2 drives the auger 3 to rotate, conveying the mixed compound fertilizer to the discharge pipe 4. The fertilizer falls downwards through the discharge pipe 4 into the granulation mechanism for subsequent granulation. After the fertilizer is discharged from the mixing drum 6, the plug plate 12 is rotated so that the lever 13 is engaged in the limiting groove on the front of the limiting rod 14. The limiting piece 15 is moved to limit the limiting rod 14, so that the plug plate 12 blocks the discharge port. Then, multiple fertilizers are poured into the mixing drum 6 according to the ratio for continuous operation. Thus, when operating, the worker only needs to pour multiple fertilizers into the mixing drum 6 according to the ratio and open and close the plug plate 12 to complete the mixing and feeding of multiple fertilizers before granulation, which simplifies the operation steps and reduces the labor of workers.

[0029] One end of the spiral auger 3 is fixedly connected to the first motor 2, and the top of the stirring shaft 9 is fixedly connected to the second motor 8.

[0030] Through the above technical solution, the fixed connection between the spiral auger 3 and the first motor 2 realizes the function of conveying compound fertilizer, while the fixed connection between the stirring shaft 9 and the second motor 8 realizes the function of stirring compound fertilizer.

[0031] There are four scrapers 10, and the four scrapers 10 are arranged in a circular array.

[0032] With the above technical solution, four scrapers 10 are arranged in a ring array on the stirring shaft 9, which can more effectively scrape and turn over the various fertilizers in the mixing drum 6, thereby improving the uniformity and efficiency of mixing.

[0033] The top of the feeding cylinder 1 is fixedly connected to a first support rod, and one end of the first support rod is fixedly connected to the mixing cylinder 6.

[0034] Through the above technical solution, the feeding cylinder 1 and the mixing cylinder 6 are stably connected by the first support rod, ensuring their coordinated operation.

[0035] The granulation mechanism includes a housing 16. Two support plates 18 are fixedly connected to the top of the housing 16. A second hopper 17 is fixedly connected to the top of the two support plates 16. Two rotating shafts 19 are rotatably connected between the two support plates 18. Pressure rollers 20 are fixedly connected to the surface of each of the two rotating shafts 19. The right side of each of the two rotating shafts 19 moves through the right support plate 18 and extends to its outside. First gears 21 that mesh with each other are fixedly connected to the right side of the two rotating shafts 19. A third motor 22 is fixedly connected to the left side of the left support plate 18. The output end of the third motor 22 is fixedly connected to one of the rotating shafts 19.

[0036] With the above technical solution, after the mixed compound fertilizer is discharged from the discharge pipe into the second hopper 17, one of the rotating shafts 19 is driven to rotate by the third motor 22. Since the right side of the two rotating shafts 19 is fixedly connected to the meshing first gear 21, the meshing of the first gear 21 drives the other rotating shaft 19 to rotate, causing the pressure roller 20 to rotate. The surface of the pressure roller 20 is provided with forming grooves for compound fertilizer forming. The pressure roller 20 presses the compound fertilizer into granular blocks through the mutual squeezing action.

[0037] A fourth motor 23 is fixedly connected to the left side of the housing 16. Two crushing shafts 24 are rotatably connected inside the housing 16. The left side of one of the crushing shafts 24 is fixedly connected to the output end of the fourth motor 23. Multiple crushing rollers 25 are fixedly connected to the surfaces of both crushing shafts 24. The right sides of both crushing shafts 24 movably penetrate the housing 16 and extend to its outside. The right sides of both crushing shafts 24 are fixedly connected to mutually meshing second gears 26.

[0038] Through the above technical solution, the compound fertilizer after pressing will be in the form of granules and blocks. The granules and blocks of compound fertilizer fall into the shell 16. The fourth motor 23 drives one of the crushing shafts 24 to rotate. Since the two crushing shafts 24 are fixedly connected to the right side of the two crushing shafts 24 and mesh with each other, the other crushing shaft 24 rotates, thereby causing the crushing roller to crush the granules and blocks of compound fertilizer into granules, thus achieving granulation.

[0039] A filter screen 27 is inclinedly arranged inside the housing 16. A finished product outlet is provided on the left side of the housing 16, and a waste product outlet is provided on the front side of the housing 16.

[0040] Through the above technical solution, fine particles and fertilizer residue are filtered out by the filter screen 27 and fall into the waste discharge port for easy subsequent recycling. The qualified granular compound fertilizer is discharged from the finished product discharge port on the left. The inclined filter screen 27 helps the material to slide down naturally under the action of gravity and be screened by the filter screen.

[0041] Its working principle is as follows: Multiple fertilizers are poured into the mixing drum 6 according to the specified ratio. The second motor 8 drives the mixing shaft 9 to rotate, causing the mixing rod 11 and scraper 10 to rotate. The rotation of the scraper 10 prevents the fertilizer from adhering to the inner wall of the mixing drum 6. The rotation of the mixing rod 11 thoroughly mixes the fertilizer. After mixing, the limiting plate 15 is rotated, and the lever 13 drives the blocking plate 12 to rotate, releasing the limit on the discharge port and allowing the mixed fertilizer to fall in. After the compound fertilizer is discharged, the first motor 2 drives the auger 3 to rotate, conveying the mixed compound fertilizer to the discharge pipe 4. The fertilizer falls downwards into the second hopper 17 through the discharge pipe 4. The third motor 22 drives one of the rotating shafts 19 to rotate. Since the right sides of the two rotating shafts 19 are fixedly connected to meshing first gears 21, the meshing of the first gears 21 drives the other rotating shaft 19 to rotate, causing the pressure roller 20 to rotate. The surface of the pressure roller 20 is provided with forming grooves for compound fertilizer formation. The pressure rollers 20 press the compound fertilizer through mutual squeezing. The compound fertilizer, in granular and blocky form, falls into the housing 16. A fourth motor 23 drives one of the crushing shafts 24 to rotate. Since the two crushing shafts 24 are fixedly connected to the right side by meshing second gears 26, the other crushing shaft 24 rotates, causing the crushing rollers to crush the granular compound fertilizer into smaller granules. Fine particles and fertilizer residue are filtered out through a filter screen 27 and fall into the waste discharge port for subsequent recycling. The qualified granular compound fertilizer exits from the finished product outlet on the left side. After the fertilizer is discharged from the mixing drum 6, the first motor 2, the third motor 22, and the fourth motor 23 can be started for subsequent feeding and granulation operations. The internal wiring of each motor is existing technology and will not be described again. Then, rotate the plugging plate 12 to make the lever 13 engage in the limiting groove on the front of the limiting rod 14, and move the limiting piece 15 to limit the limiting rod 14, so that the plugging plate 12 blocks the discharge port. Then, continue to pour various fertilizers into the mixing drum 6 according to the ratio for continuous operation.

[0042] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
