Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer granulation, in particular to a fertilizer granulation device. Background Art

[0002] When granulating fertilizers, disc granulator is a commonly used granulating machine. It uses the centrifugal force generated by the machine during rotation to squeeze the fertilizers and complete the granulation during multiple rotations. The disc granulator is lined with high-strength fiberglass, which has the advantages of high granulation rate, stable operation, durable equipment and long service life.

[0003] The existing disc granulator pours the fertilizer granules into the screening box when discharging. However, during the production process, adhesives and water are added to the fertilizer raw materials to assist in granulation of the fertilizer. As a result, the outer surface of the fertilizer granules becomes sticky and occasionally sticks to the filter screen, causing the filter holes to be blocked, resulting in affected screening efficiency. Manual shaking of the filter screen is required to continue the secondary screening, which is inconvenient to use. In order to solve the above problems, we propose a fertilizer granulating device.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0030] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] The user pre-processes the raw materials to be granulated, such as grinding, mixing, and wetting. The pre-treated raw materials are then evenly placed onto the disc of the disc granulator. The disc generates centrifugal force on the raw materials, and gravity simultaneously acts on them, forming a layer of material of a certain thickness. A binder, such as water or a binder solution, can be added to the layer as needed. This addition aids in particle formation and improves particle strength. Under the influence of the disc's rotation and centrifugal force, the raw materials gradually form spherical particles. Simultaneously, the particles continuously roll, rub, and collide within the disc, gradually smoothing the particle surface and increasing its strength. Under the influence of gravity, the formed particles slide off the edge of the disc and are collected.

[0032] In the related art, when discharging, the fertilizer particles are poured into the screening box. However, during the production process, adhesives and water are added to the fertilizer raw materials to assist in granulation of the fertilizer. As a result, the outer surface of the fertilizer particles is sticky and occasionally sticks to the filter screen, causing the filter holes to be clogged, resulting in affected screening efficiency. Manual shaking of the filter screen is required to continue the secondary screening, which is inconvenient to use.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a fertilizer granulating device, in which the fertilizer particles slide out of the disc from the edge of the disc and enter the screening box 21 and fall on the screen plate 22. One end of the screen plate 22 is rotatably connected to the screening box 21. The horizontal height of the rotating end of the screen plate 22 is lower than the other end. Therefore, under the action of gravity, the fertilizer particles will move downward along the screen plate 22 and roll out from the discharge port 211. However, the outer surface of the fertilizer particles has adhesiveness, so some fertilizer particles will adhere to the screen plate 22, resulting in the screening efficiency of the screen plate 22 being affected. The user turns on the motor 24, the main shaft of the motor 24 passes through the screening box 21 and is fixedly connected to the center of the protrusion 241, and the protrusion 24 The top of the sieve plate 22 abuts against the bottom of the sieve plate 22. At the same time, springs 1 23 are provided at the bottom of both ends of the sieve plate 22. Therefore, as the main shaft of the motor 24 rotates, the top of the protrusion 241 rotates accordingly, and the protrusion 241 and the sieve plate 22 reciprocate and abut. The spring 1 23 can support the sieve plate 22. Under the elastic force of the spring 1 23, the movement of the sieve plate 22 is more stable. The sieve plate 22 vibrates under the pushing action of the protrusion 241. The fertilizer particles adhered to the sieve plate 22 are vibrated and continue to move on the sieve plate 22. The smaller fertilizer particles fall from the sieve holes on the sieve plate 22 and fall onto the slide plate 28. Under the action of gravity, they slide out from the discharge port 211. The user collects fertilizer particles of two sizes respectively.

[0034] The present application is described below with reference to specific embodiments and in conjunction with the accompanying drawings:

[0035] Combine Figures 1-6 , the embodiment of the present application provides a fertilizer granulating device, including a granulating device 1; the granulating device 1 includes: a top plate 12 is provided on the top of the base 11, and a motor 13 and a reducer 14 are provided on the top plate 12; a disc 15 is rotatably arranged on the base 11 through a main shaft; a fixing frame 16 is provided on the top plate 12, and a scraper 17 is provided on the fixing frame 16; a screening device 2 is provided on the granulating device 1, and the screening device 2 includes: a screening box 21 is provided in front of the base 11 and below the disc 15, and a discharge port 211 is provided on the screening box 21; a sieve plate 22 is rotatably provided on the screening box 21; a motor 24 is provided on the outer wall of the screening box 21, and a rotating shaft of the motor 24 passes through the screening box 21 and is provided with a protrusion 241, and the protrusion 241 abuts against the bottom of the sieve plate 22; a slide plate 28 is provided inside the screening box 21 and below the sieve plate 22.

[0036] The user pre-processes the raw materials to be made into granules, such as grinding, mixing, and wetting, and then evenly puts the pre-processed raw materials onto the disc 15 of the granulating device 1, turns on the motor 13, and a gear is provided on the output shaft of the motor 13. The motor 13 drives the gear to rotate. At the same time, the gear on the motor 13 is connected to the gear on the reducer 14 through a transmission belt, so that the motor 13 can drive the reducer 14 to work, and the shaft at the other end of the reducer 14 is driven to rotate. A gear is provided on the shaft, and the gear is meshed with the gear on the back of the disc 15, so that the disc 15 can be controlled to rotate. The raw materials generate centrifugal force under the action of the rotation of the disc, and at the same time When the disc is rotated and centrifugal force is applied, the raw material gradually forms spherical particles. The scraper 17 on the fixed frame 16 is arranged above the disc 15. During the rotation, the scraper 17 will flatten and compact the fertilizer raw material. In this process, the fertilizer particles will become more compact and strong. At the same time, the particles will continue to roll, rub and collide in the disc, making the particle surface gradually smooth and increasing the strength. Under the action of gravity and centrifugal force, the formed particles will fall out of the disc after reaching a certain size. The bottom edge of the disc 15 slides out, so the formed particles of different sizes slide out of the disc from the edge of the disc and enter the screening box 21 and fall on the screen plate 22 (this part is the existing technology and is common knowledge). One end of the screen plate 22 is rotatably connected to the screening box 21. The horizontal height of the rotating end of the screen plate 22 is lower than the other end. Therefore, under the action of gravity, the fertilizer particles will move downward along the screen plate 22 and roll out from the discharge port 211. However, the outer surface of the fertilizer particles is adhesive, so some fertilizer particles will adhere to the screen plate 22, resulting in the screening efficiency of the screen plate 22 being affected. The user turns on the motor 24, the main shaft of the motor 24 passes through the screening box 21 and is fixedly connected to the center of the protrusion 241. The protrusion 24 The top of the sieve plate 22 abuts against the bottom of the sieve plate 22. At the same time, springs 1 23 are provided at the bottom of both ends of the sieve plate 22. Therefore, as the main shaft of the motor 24 rotates, the top of the protrusion 241 rotates accordingly, and the protrusion 241 and the sieve plate 22 reciprocate and abut. The spring 1 23 can support the sieve plate 22. Under the elastic force of the spring 1 23, the movement of the sieve plate 22 is more stable. The sieve plate 22 vibrates under the pushing action of the protrusion 241. The fertilizer particles adhered to the sieve plate 22 are vibrated and continue to move on the sieve plate 22. The smaller fertilizer particles fall from the sieve holes on the sieve plate 22 and fall onto the slide plate 28. Under the action of gravity, they slide out from the discharge port 211. The user collects fertilizer particles of two sizes respectively.

[0037] Specifically, the reducer 14 is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine, which can improve transmission efficiency and provide better power for the rotation of the disc 15.

[0038] In some embodiments, one end of the sieve plate 22 and the slide plate 28 is rotatably connected to the sieve box 21, and a spring 23 is disposed at the bottom of the other end. The spring 23 is fixedly connected to the sieve box 21. The spring 23 supports the sieve plate 22, and the elastic force of the spring 23 prevents the sieve plate 22 from moving up and down excessively, and the elastic force of the spring 23 makes the movement of the sieve plate 22 more stable.

[0039] In some embodiments, the sieve plate 22 is symmetrically provided with slide rails 251, and the scraper 25 is slidably connected to the sieve plate 22 via the slide rails 251. The user sprays water from an external source on the sieve plate 22. The fertilizer residue is small and dispersed, and is easily decomposed when exposed to water. The user then uses the scraper 25 to move on the sieve plate 22 to clean the top of the sieve plate 22 and remove the fertilizer residue that has fallen on the sieve plate 22.

[0040] In some embodiments, a silicone layer is provided at the bottom of the scraper 25. The silicone layer has good friction and poor adhesion, and will not be easily contaminated by fertilizer, saving the user effort in cleaning.

[0041] In some embodiments, a protective frame 26 is provided on the sieve plate 22, and the protective frame 26 can accommodate the scraper 25. The provision of the protective frame 26 can prevent fertilizer particles from falling on the scraper 25, causing the scraper 25 to be wrapped by fertilizer and requiring the user to clean it.

[0042] In some embodiments, a rod 27 is provided through the protective frame 26, and the rod 27 is plugged into the top of the scraper 25. The rod 27 can be provided to limit the scraper 25 inside the protective frame 26 when the scraper 25 is not in use. The structure is simple and easy to use, saving time and effort for the user.

[0043] In some embodiments, the insertion rod 27 is sleeved with a second spring 271. Under the elastic force of the second spring 271, the user can pull up the insertion rod 27 and the insertion rod 27 can be quickly reset without the user having to remove the insertion rod 27. Moreover, under the elastic force of the second spring 271, the insertion rod 27 and the scraper 25 are more tightly connected.

[0044] In some embodiments, the slide plate 28 is provided with a polytetrafluoroethylene coating. The polytetrafluoroethylene coating has a smooth and non-stick surface, so small fertilizer particles can slide along the slide plate 28 and out of the discharge port 211 without sticking to the slide plate 28. The screen plate 22 is not provided with this coating to prevent the fertilizer particles from sliding too quickly on the coating and affecting the screening efficiency.

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
