Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of granulators, in particular to a fertilizer granulator. Background Art
[0002] Fertilizer is the abbreviation of chemical fertilizer. It is made by chemical or physical methods and contains one or more nutrients required for the growth of crops. It is indispensable in today's agricultural production and can provide the nutrients needed for the growth of crops. Fertilizer granulator is a mechanical equipment that plays a key role in the fertilizer production process. It undertakes the important task of making fertilizer raw materials into granules.
[0003] The shortcomings of existing fertilizer granulators are as follows: During the operation of the equipment, a large amount of dust will be generated due to the mutual friction and extrusion between the materials and the collision with the equipment parts. A large amount of dust will enter the air directly through the dust exhaust port under the drive of the airflow, which will not only cause serious pollution to the working environment around the equipment, but also make the entire working area filled with a large amount of dust particles, resulting in reduced visibility and a sharp decline in air quality; and in such a seriously polluted working environment for a long time, operators will inevitably inhale these harmful dusts, posing a serious threat to their health. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a fertilizer granulator, comprising a collection box and a purification structure assembled on the top of the collection box, and a feeding hopper in the middle of the collection box and connected thereto, wherein the top of the feeding hopper is rotatably connected to a sealing cover, and the bottom of the collection box is fixedly connected to a crushing structure;
[0005] The purification structure includes a purification box and two air pumps mounted on the top of the purification box, and a through pipe located in front of the purification box. The output end of the air pump is connected to an exhaust pipe, and the input end of the air pump is connected to an exhaust pipe. Three guide pipes are connected to the middle of the back of the through pipe. The three guide pipes are connected to the interior of the aggregate box. Four air filter elements are provided on the inner wall of the purification box, and four exhaust fans are provided on the back of the purification box.
[0006] Preferably, the crushing structure includes a crusher connected to the bottom wall of the aggregate box, and a discharge hopper is provided on the left side of the crusher.
[0007] Preferably, it also includes a forming structure located on the left side and inside of the aggregate box, the forming structure including a servo motor and two pressure roller molds located below the feeding hopper and horizontally opposed, and a gear A fixedly connected to the output end of the servo motor, the outer wall of the gear A is rotatably connected to the gear B.
[0008] Preferably, the A gear and the B gear are fixedly connected to two pressing roller molds on one side close to the aggregate box.
[0009] Preferably, the back side of the through-pipe is connected to the front side of the crusher, and the other end of the exhaust pipe is connected to the top of the through-pipe.
[0010] Preferably, the other end of the exhaust pipe extends to the interior of the purification box.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] The utility model provides a sealing cover on the top of the feeding hopper. When the feeding work is completed, the sealing cover is closed in time. In this way, the dust that is easy to escape during the feeding process is effectively confined in a relatively closed space, which greatly reduces the diffusion of dust into the external environment and lays a good foundation for subsequent dust treatment. Then the purification structure plays an important role. Through the operation of the air pump, the dust generated in the aggregate box and the crusher during the production operation is continuously pumped to the purification box through the through pipe. In this process, the air pump is like a powerful power engine, ensuring that the dust can be efficiently and stably transported to the purification box. When the dust-containing air enters the purification box, the four air filters can perform multi-level and all-round fine filtration on the incoming dust-containing air. From large particles of dust to tiny dust particles, they are effectively intercepted and adsorbed under the filtering action of the air filter. Finally, under the promotion of the exhaust fan, the fresh air that has been filtered and purified layer by layer is discharged, thereby reducing the problem of dust being directly discharged through the exhaust port during the operation of the machine, causing dust diffusion.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] like Figures 1 to 5 As shown, the utility model provides a fertilizer granulator, comprising a collection box 1 and a purification structure 2 assembled on the top of the collection box 1, and a feeding hopper 3 in the middle of the collection box 1 and connected thereto, the top of the feeding hopper 3 is rotatably connected to a sealing cover 4, and the bottom of the collection box 1 is fixedly connected to a crushing structure 5;
[0021] The purification structure 2 includes a purification box 21 and two air pumps 22 assembled on the top of the purification box 21, and a through pipe 23 located in front of the purification box 21. The output end of the air pump 22 is connected to an exhaust pipe 24, and the input end of the air pump 22 is connected to an exhaust pipe 25. The middle part of the back of the through pipe 23 is connected to three guide pipes 26, and the three guide pipes 26 are connected to the interior of the aggregate box 1. Four air filter elements 27 are provided on the inner wall of the purification box 21, and four exhaust fans 28 are provided on the back of the purification box 21.
[0022] The above solution is adopted: by setting a sealing cover 4 on the top of the feeding hopper 3, when the feeding work is completed, the sealing cover 4 is closed in time, so that the dust that is easy to escape during the feeding process is effectively confined in a relatively closed space, greatly reducing the diffusion of dust to the external environment, laying a good foundation for subsequent dust treatment, and then the purification structure 2 plays an important role. Through the operation of the air pump 22, the dust generated in the aggregate box 1 and the crusher 51 during the production operation is continuously pumped to the purification box 21 through the through pipe 23. In this process, the air pump 22 is still Like a powerful power engine, it ensures that dust can be efficiently and stably transported into the purification box 21. When the dust-laden air enters the purification box 21, the four air filters 27 can perform multi-level and all-round fine filtration on the incoming dust-laden air. From large particles of dust to tiny dust particles, they are all effectively intercepted and adsorbed under the filtering action of the air filter 27. Finally, under the push of the exhaust fan 28, the fresh air that has been filtered and purified layer by layer is discharged, thereby reducing the problem of dust being directly discharged through the exhaust port during the operation of the machine, causing dust to spread.
[0023] like Figures 1 to 5 As shown, the crushing structure 5 includes a crusher 51 connected to the inner bottom wall of the aggregate box 1, and a discharge hopper 52 is provided on the left side of the crusher 51.
[0024] The above scheme is adopted: the discharge hopper 52 is in a vertically downward state. This design layout plays an important role in practical applications. On the one hand, it can ensure the smooth discharge of materials. On the other hand, due to the special vertically downward structure and angle setting, the internal materials are discharged more concentratedly and orderly under the action of gravity, which greatly reduces the dust phenomenon caused by air flow disturbance or material splashing during the discharge process, thereby effectively reducing the possibility of dust being discharged through the discharge hopper 52, and reducing the amount of dust escaping to the external environment. While improving the discharge efficiency, it achieves effective control of dust emissions. The crusher 51 is an existing device, which can cut the die-cast sheet material into particles.
[0025] like Figures 1 to 5 As shown, it also includes a forming structure 6 located on the left side and inside of the aggregate box 1. The forming structure 6 includes a servo motor 61 and two pressure roller molds 62 located below the feeding hopper 3 and horizontally opposed to each other, and an A gear 63 fixedly connected to the output end of the servo motor 61. The outer wall of the A gear 63 is rotatably connected to the B gear 64. The A gear 63 and the B gear 64 are fixedly connected to the two pressure roller molds 62 on one side close to the aggregate box 1.
[0026] With the above solution, the precisely controlled servo motor 61 begins to operate, and the rotation of its output shaft drives the connected gear A 63 to rotate. When gear A 63 begins to rotate under the drive of the servo motor 61, the meshing of gear A 63 and gear B 64 allows this mechanical transmission to effectively drive gear B 64 to rotate, thereby forming a stable and efficient relative rotational motion. These two gears are respectively connected to corresponding roller molds 62. The relative rotation of gear A 63 and gear B 64 can accurately drive the two roller molds 62 to rotate relative to each other. As the two roller molds 62 begin to rotate relative to each other, the material placed in the space between them is subjected to the strong extrusion pressure from the roller mold 62. Under the action of this continuous and uniform extrusion pressure, the material is gradually squeezed into a sheet-like form. These sheets of material, pushed out of the range of the roller mold 62 by the continuous rotation of the roller mold 62, then naturally fall into the crusher 51 below due to gravity, ready for subsequent crushing processing.
[0027] like Figures 1 to 5 As shown, the back of the through-pipe 23 is connected to the front of the crusher 51 , the other end of the exhaust pipe 24 is connected to the top of the through-pipe 23 , and the other end of the exhaust pipe 25 extends to the interior of the purification box 21 .
[0028] The above solution is adopted: the exhaust pipe 25 is connected to the through pipe 23, and the exhaust pipe 25 and the through pipe 23 are respectively connected to the aggregate box 1 and the crusher, so that the dust generated by starting the sub-pump when the machine is running is sucked into the purification box 21 through the through pipe 23 by the strong suction force of the air pump 22.
[0029] The working principle and use process of this utility model:
[0030] First, pour the material into the feeding hopper 3, then close the sealing cover 4, and start the servo motor 61. The rotation of its output shaft can drive the A gear 63 connected to it to rotate. When the A gear 63 starts to rotate under the drive of the servo motor 61, the A gear 63 can effectively drive the B gear 64 to rotate, and these two gears are respectively connected to the corresponding roller molds 62. The relative rotation of the A gear 63 and the B gear 64 can accurately drive the two roller molds 62 to rotate relative to each other. As the two roller molds 62 start to rotate relative to each other, the material placed in the space between them is subjected to a strong extrusion pressure from the roller mold 62. Under the action of this continuous and uniform extrusion pressure, the material is gradually squeezed into a sheet-like form. These materials squeezed into sheets , under the continuous rotation and pushing of the roller mold 62, it breaks away from the range of action of the roller mold 62, and then falls naturally to the crusher 51 below due to gravity, and is then cut and granulated by the crusher 51. At the same time, the air pump 22 is started to pump the dust generated in the aggregate box 1 and the crusher 51 during the production operation to the purification box 21 through the through pipe 23. When the dust-laden air enters the purification box 21, the four air filters 27 can perform multi-level and all-round fine filtration on the incoming dust-laden air. From large particles of dust to tiny dust particles, they are effectively intercepted and adsorbed under the filtering action of the air filter 27. Finally, under the push of the exhaust fan 28, the fresh air that has been filtered and purified layer by layer is discharged.
