Abstract

Technical Field
[0001] This utility model relates to the field of granulation technology for pesticide and fertilizer granules, specifically a high-tower granulation device for pesticide and fertilizer granules. Background Technology
[0002] Pesticide-fertilizer granules are compound formulations made by combining the active ingredients of pesticides and fertilizers into granules through a specific process. The granule shape obtained by the granulation device is convenient for mechanical sowing and facilitates precise application by fertilization equipment such as broadcasters and row seeders, making it suitable for large-scale agricultural production. However, there are still some problems with the current granulation devices for pesticide-fertilizer granules.
[0003] As disclosed in application number 202323551897.0, a high-tower fertilizer granulation device includes a granulation box, which is used for positioning during granulation. An auxiliary feeding mechanism is fixedly mounted on the top of the granulation box, and a granulation mechanism is fixedly mounted on the inner wall of the granulation box. The granulation mechanism includes a granulation cylinder, and multiple granulation grooves are formed on the outer wall of the granulation cylinder. This invention uses a rotating frame fixed to the inner wall of a first positioning toothed ring to drive multiple granulation plates to reciprocate and cut against the outer wall of the granulation grooves, thereby enabling the high-tower fertilizer granulation device to granulate. The high speed is achieved by rotating the second positioning toothed ring, which drives the positioning ring fixed at the bottom and the four limiting frames to rotate. This allows the four limiting frames to drive multiple spray heads to spray powdered fertilizer from the high-tower granulation equipment. This isolates and protects the granulated fertilizer from the powdered fertilizer, improving the granulation speed and efficiency. However, it still has the problem of poor applicability. It is not easy to flexibly change the granulation screen holes of different specifications according to the granulation size requirements. Moreover, the granulation screen holes of the device are easily blocked when the product particles move, affecting the processing efficiency. Therefore, we propose a new type of high-tower fertilizer granulation device. Utility Model Content
[0004] The purpose of this invention is to provide a high-tower fertilizer granulation device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-tower granulation device for fertilizer and pharmaceutical granules, comprising a tower body, a PLC controller installed on the outer wall of the tower body, a drive housing provided on the top of the tower body, a hollow driven wheel movably connected at the middle position of the drive housing, drive wheels meshing on both sides of the hollow driven wheel, servo motors matching the drive wheels installed on both sides of the bottom of the drive housing, a feed inlet provided on the top of the drive housing, a feeding pump installed on the feed inlet, a first air guide plate and a second air guide plate respectively provided at the bottom of both ends of the tower body, a cold air fan installed on one side of both the first air guide plate and the second air guide plate, an inner roller fixed on the hollow driven wheel, an adjustable discharge trough threaded to the bottom of the inner roller, an ultrasonic generator installed on one side of the adjustable discharge trough, a perforated screening disc installed inside the adjustable discharge trough by screws, and a transducer vibrator installed at the bottom of the perforated screening disc.
[0006] Preferably, both ends of the bottom of the tower body are provided with fixed legs, and the fixed legs are provided with screw holes inside.
[0007] Preferably, both the first air guide plate and the second air guide plate are connected to the input end of the air cooler, and one end of both the first air guide plate and the second air guide plate is uniformly provided with a spray nozzle extending into the interior of the tower body.
[0008] Preferably, the inner roller has a hollow structure, and the vertical center line of the inner roller and the vertical center line of the hollow driven wheel are on the same vertical line.
[0009] Preferably, the top of the adjustable discharge trough is provided with a threaded assembly pipe that matches the tower body.
[0010] Preferably, there are two drive wheels, and a limit bearing is provided between the drive wheels and the drive housing.
[0011] Preferably, both the tower body and the inner roller are coated with a nano-ceramic anti-stick protective layer, which improves the anti-stick effect of the inner wall of the device and reduces maintenance costs.
[0012] Preferably, the inner roller is provided with air vents evenly, and a hollow bearing is provided between the inner roller and the tower body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) The high-tower fertilizer granulation device optimizes its performance by installing a cold air blower, etc. On the one hand, the PLC controller controls the start of the feeding pump and the cold air blower. At this time, the feeding pump can extract the liquid product from the hot melt box of the raw material connected to the outside of the pipeline and spray it from top to bottom into the inner drum. At the same time, the cold air blowers on the first air guide plate and the second air guide plate are started, and the cold air is blown evenly from bottom to top into the inner drum through the spray nozzles extending into the tower body. This cold air then enters the inner drum evenly through the air vents on the inner drum. By contacting the hot melt raw material from top to bottom, the product granules are solidified. This dynamic The spray structure enables efficient batch granulation of fertilizer raw materials, improving processing efficiency. On the other hand, the servo motor starts to drive the drive wheel to rotate inside the drive housing, which in turn drives the hollow driven wheel connected to the drive wheel to rotate. This, in turn, drives the inner roller fixed to the hollow driven wheel to rotate inside the tower. The rotation of the inner roller causes the initially formed fertilizer granules inside to collide with each other or with the device as they fall. The impact helps to adjust the shape and uses kinetic energy to make the product surface more rounded, improving granulation quality and solving the problems of surface roughness and low roundness in high tower granulation.
[0015] (2) The high-tower fertilizer granulation device optimizes its structure by installing a porous sieve disc, etc. On the one hand, when the fertilizer granules fall onto the porous sieve disc, only qualified products can be discharged through the sieve holes on the porous sieve disc. On the other hand, the ultrasonic generator on the outer wall of the adjustable discharge trough can be activated to convert electrical energy into high-frequency energy, and then converted into ultrasonic vibration by the action of the transducer vibrator. Then, by utilizing the contact action between the radiation surface of the transducer vibrator and the porous sieve disc, the high-frequency ultrasonic vibration causes the granules that fall onto it but cannot pass through to be discharged. The product discharged from the filter holes is in a suspended state, which effectively avoids the problem of poor material flow caused by clogging and is conducive to continuous processing. On the other hand, users can use the threaded connection between the threaded assembly pipe and the tower body to independently disassemble and assemble the adjustable discharge chute. Then, using the installation structure formed by screws between the adjustable discharge chute and the multi-hole screening disc, the multi-hole screening disc can be independently disassembled and replaced. This not only facilitates the cleaning of the multi-hole screening disc, but also allows for the replacement of multi-hole screening discs with different diameter screen holes according to actual granulation needs, thus enhancing applicability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figures 1-5 An embodiment of this utility model is provided: a high-tower fertilizer granulation device, including a tower body 8, a PLC controller 9 installed on the outer side wall of the tower body 8, a drive housing 2 provided on the top of the tower body 8, a hollow driven wheel 13 movably connected at the middle position of the drive housing 2, a drive wheel 12 meshing with both sides of the hollow driven wheel 13, and a servo motor 10 matching the drive wheel 12 installed on both sides of the bottom of the drive housing 2;
[0024] Two drive wheels 12 are provided, and a limit bearing is provided between the drive wheels 12 and the drive housing 2;
[0025] The top of the drive housing 2 is provided with a feed inlet 11, and a feed pump 1 is installed on the feed inlet 11. The bottom of both ends of the tower body 8 is provided with a first air guide plate 4 and a second air guide plate 7 respectively. A cooler 3 is installed on one side of both the first air guide plate 4 and the second air guide plate 7.
[0026] An inner roller 14 is fixed on the hollow driven wheel 13;
[0027] The first air guide plate 4 and the second air guide plate 7 are both connected to the input end of the air cooler 3. One end of the first air guide plate 4 and the second air guide plate 7 are evenly provided with spray nozzles extending into the tower body 8.
[0028] Ventilation holes are evenly distributed on the inner roller 14, and a hollow bearing is provided between the inner roller 14 and the tower body 8.
[0029] During use, the PLC controller 9 controls the start of the feeding pump 1 and the cooling fan 3. At this time, the feeding pump 1 can extract the liquid product from the inside of the raw material hot melt box connected to the outside of the pipeline and spray it from top to bottom into the inside of the inner roller 14. At the same time, the cooling fan 3 on the first air guide plate 4 and the second air guide plate 7 starts, and blows cold air evenly from bottom to top into the inner roller 14 through the spray nozzles extending into the tower body 8. This cold air then enters the inside of the inner roller 14 evenly through the air vents on the inner roller 14. By contacting the hot melt raw material from top to bottom, the product particles are solidified. This dynamic spray structure can realize the batch and efficient granulation of pesticide and fertilizer raw materials, and improve the processing efficiency.
[0030] An adjustable discharge chute 6 is threadedly connected to the bottom of the inner roller 14. An ultrasonic generator 16 is installed on one side of the adjustable discharge chute 6. A perforated screening disc 17 is installed inside the adjustable discharge chute 6 by screws. A transducer vibrator 18 is installed at the bottom of the perforated screening disc 17.
[0031] The top of the adjustable discharge chute 6 is equipped with a threaded assembly pipe 15 that matches the tower body 8;
[0032] During use, when the fertilizer granules fall onto the porous sieve disc 17, only qualified products can pass through the sieve holes and be discharged. Meanwhile, the ultrasonic generator 16 on the outer wall of the adjustable discharge trough 6 is activated, converting electrical energy into high-frequency energy. This energy, combined with the action of the transducer vibrator 18, is then converted into ultrasonic vibration. The contact between the radiating surface of the transducer vibrator 18 and the porous sieve disc 17, based on the high-frequency ultrasonic vibration, causes the products falling onto it but unable to pass through the filter holes to remain suspended, effectively preventing clogging. The resulting problem of poor material feeding is conducive to achieving continuous processing. On the other hand, users can use the threaded connection between the threaded assembly pipe 15 and the tower body 8 to independently disassemble and assemble the adjustable discharge chute 6. Then, using the installation structure formed by screws between the adjustable discharge chute 6 and the multi-hole screening disc 17, the multi-hole screening disc 17 can be independently disassembled and replaced. This not only facilitates the cleaning of the multi-hole screening disc 17, but also allows for the replacement of the multi-hole screening disc 17 with different diameter screen holes according to actual granulation needs, thus enhancing its applicability.
[0033] Both ends of the bottom of the tower body 8 are provided with fixed support legs 5, and the inside of the fixed support legs 5 is provided with screw holes;
[0034] The inner roller 14 has a hollow structure, and the vertical center line of the inner roller 14 and the vertical center line of the hollow driven wheel 13 are on the same vertical line.
[0035] Both the tower body 8 and the inner roller 14 are coated with a nano-ceramic anti-stick protective layer, which improves the anti-stick effect of the inner wall of the device and reduces maintenance costs.
[0036] In use, the following steps are taken: First, the user can use the screw holes on the fixed support legs 5 at the bottom of the tower body 8 to fix the bottom of the device with screws, thus improving the stability of the device. During actual operation, the PLC controller 9 controls the feeding pump 1 and the cooling fan 3 to start. At this time, the feeding pump 1 can draw out the liquid product from the raw material hot melt box connected to the outside of the pipeline and spray it from top to bottom into the inner roller 14. At the same time, the cooling fan 3 on the first air guide plate 4 and the second air guide plate 7 starts, and blows cold air evenly from bottom to top into the inner roller 14 through the spray nozzles extending into the tower body 8. This cold air then passes through the inner roller... The air vents on cylinder 14 evenly introduce air into the interior of inner roller 14. Through contact with the hot-melt raw material flowing downwards, the product granules solidify. This dynamic spraying structure enables efficient batch granulation of fertilizer raw materials, improving processing efficiency. Furthermore, servo motor 10 starts to drive drive wheel 12 to rotate inside drive housing 2, which in turn drives hollow driven wheel 13, meshing with drive wheel 12, to rotate. This, in turn, drives inner roller 14, fixed to hollow driven wheel 13, to rotate inside tower body 8. The rotation of inner roller 14 causes the initially formed fertilizer granules inside to collide with each other as they fall. The impact with the device helps adjust the shape, using kinetic energy to make the product surface more rounded, improving granulation quality and solving the problems of surface roughness and low roundness in high-tower granulation. Furthermore, when the fertilizer granules fall onto the porous sieve disc 17, only qualified products can pass through the sieve holes and be discharged. The ultrasonic generator 16 on the outer wall of the adjustable discharge trough 6 is activated, converting electrical energy into high-frequency energy, which, in conjunction with the transducer vibrator 18, is converted into ultrasonic vibration. Then, utilizing the contact between the radiating surface of the transducer vibrator 18 and the porous sieve disc 17, high-frequency ultrasonic vibration is generated. Vibration causes products that fall onto the screen but cannot pass through the filter holes to remain suspended, effectively avoiding the problem of poor material discharge caused by blockage. This facilitates continuous processing. On the other hand, users can use the threaded connection between the threaded assembly pipe 15 and the tower body 8 to independently disassemble and assemble the adjustable discharge chute 6. Then, using the installation structure formed by screws between the adjustable discharge chute 6 and the multi-hole screening disc 17, the multi-hole screening disc 17 can be independently disassembled and replaced. This facilitates cleaning of the multi-hole screening disc 17 and allows for the replacement of multi-hole screening discs 17 with different diameter screen holes according to actual granulation needs, thus enhancing applicability.
