Description

Technical Field

[0001] This utility model relates to the field of granulation technology, specifically a disc granulator for fertilizer production. Background Technology

[0002] The fertilizer production process mainly includes raw material preparation, mixing, granulation and filling. Among them, the granulation process often uses a disc granulator to ensure granulation density and pelleting rate.

[0003] The currently used disc granulator mainly includes an adjustable base, a geared motor, a sprayer, and a material tray. The adjustable base is used to adjust the tilt angle of the platform, thereby adjusting the tilt angle of the material tray to control the movement trajectory of the fertilizer in the tray. The geared motor is used to provide power for the low-speed rotation of the material tray. The sprayer and scraper installed on the platform via the gantry frame can spray the input fertilizer first and then crush it. The fertilizer gradually gathers and agglomerates to form round and compact granules.

[0004] After granulation, the disc granulator needs to discharge the granules from the disc through an additional discharge mechanism. The manual operation requires the operator to continuously apply external force to control the discharge speed and flow rate, which not only greatly increases the labor intensity of the operator, but also makes it difficult to ensure the stability of the discharge process due to the limited precision of manual operation. In addition, the functionality is relatively simple and the flexibility of use is poor.

[0005] Therefore, in order to solve the above problems, a disc granulator for fertilizer production is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a disc granulator for fertilizer production, which makes material discharge more convenient and its use more flexible, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disc granulator for fertilizer production, comprising an adjustable base, a geared motor and a gantry frame fixedly mounted on the platform of the adjustable base, a material tray connected to the output end of the geared motor, a support beam fixedly mounted on one side of the gantry frame, and a cover for shielding the material tray fixedly mounted on the other side of the gantry frame, a conveying channel mounted on the support beam via a drive assembly, one end of the conveying channel extending into the material tray, and the other end extending out of the material tray, a scraper fixedly mounted on the side of the conveying channel away from the drive assembly, and a spraying assembly mounted on the side of the cover away from the material tray.

[0008] Specifically, the drive assembly includes a first electric cylinder, a second electric cylinder, and a rotating seat. The first electric cylinder is fixedly installed at the upper end of the support beam, and the second electric cylinder is rotatably installed at the lower end of the support beam through a bearing seat. Two rotating seats are fixedly installed in the conveying channel, and the rotating seats are rotatably assembled with the push rod ends of the first electric cylinder and the second electric cylinder, respectively.

[0009] Specifically, the conveying channel includes an upper inclined section and a lower inclined section that are connected and installed together, and the angle between the upper inclined section and the bottom surface of the material tray is smaller than the angle between the lower inclined section and the bottom surface of the material tray.

[0010] Specifically, when the push rod end of the second electric cylinder extends and the push rod end of the first electric cylinder retracts, the input end of the upper inclined section separates from the bottom surface of the material tray; when the push rod end of the second electric cylinder retracts and the push rod end of the first electric cylinder extends, the input end of the upper inclined section abuts against the bottom surface of the material tray.

[0011] Specifically, the upper end of the scraper is fixedly assembled with the upper inclined section, and the included angle between the scraper and the bottom surface of the material tray is an acute angle.

[0012] Specifically, the spray assembly includes a bend, branch pipes, and nozzles. The bend is fixedly assembled with the housing. At least two pairs of branch pipes are installed along the bend. The branch pipes are evenly connected with nozzles. The nozzles pass through the housing and extend into the material tray.

[0013] Specifically, the cover is a semi-enclosed annular sheet, with the feed inlet at the center of the cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are: Convenient and stable discharge: By changing the tilt angle of the conveying channel through the drive component, the upper inclined section abuts against the bottom surface of the material tray. As the material tray continues to rotate, the fertilizer particles can be discharged along the upper and lower inclined sections to the external turnover box. There is no need for continuous manual external force control, which reduces the labor intensity of operators and ensures the stability of discharge.

[0015] Flexible and versatile: By combining different extension and retraction of the push rod ends of the first and second electric cylinders, the drive assembly can operate in multiple modes. It can adjust the distance between the scraper and the bottom of the material tray to change the particle size of the fertilizer produced; it can change the tilt angle of the scraper to adapt to the compaction intensity required for different fertilizers; and it can also realize the discharge function, thus improving the functionality of the equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 This utility model provides a disc granulator for fertilizer production, including an adjustable base 10. The adjustable base 10 has a support, a platform, and a third electric cylinder. The platform is rotatably installed in the support. The two ends of the third electric cylinder are rotatably assembled with the same side of the support and the platform, respectively. The platform can swing after the third electric cylinder extends and retracts. A reduction motor 11 and a gantry frame 2 are fixedly installed on the platform of the adjustable base 10. The output end of the reduction motor 11 is connected to and installed with a material tray 1. The reduction motor 11 is used to rotate the material tray 1 at low speed, while the gantry frame 2 provides a mounting base for other components. The above structure is the prior art and will not be described in detail here.

[0020] A support beam 7 is fixedly installed on one side of the gantry frame 2, and a cover 9 for shielding the material tray 1 is fixedly installed on the other side of the gantry frame 2. The support beam 7 is connected to a conveying channel 5 via a drive assembly 6. One end of the conveying channel 5 extends into the material tray 1, and the other end extends out of the material tray 1. The drive assembly 6 is used to swing the conveying channel 5 to switch working modes. A scraper 3 is fixedly installed on the side of the conveying channel 5 away from the drive assembly 6. The scraper 3 is used to crush the fertilizer that passes through. A spray assembly 8 is installed on the side of the cover 9 away from the material tray 1. The spray assembly 8 is used to spray water evenly onto the fertilizer to wet it.

[0021] A distance of 2-5 mm is left between the cover 9 and the material tray 1, which can block the fertilizer without affecting the rotation of the material tray 1. In addition, the cover 9 is a semi-enclosed annular sheet, which does not affect the setting of the conveying channel 5, drive component 6 and other structures. The center of the cover 9 is the feed inlet 4, and the fertilizer can be evenly dispersed to the surrounding area under the action of centrifugal force.

[0022] Please see Figure 2 The drive assembly 6 includes a first electric cylinder 64, a second electric cylinder 63, and a rotating seat 61. The first electric cylinder 64 is fixedly installed at the upper end of the support beam 7, and the second electric cylinder 63 is rotatably installed at the lower end of the support beam 7 via a bearing seat 62. Two rotating seats 61 are fixedly installed in the conveying channel 5. The rotating seats 61 are rotatably assembled with the push rod ends of the first electric cylinder 64 and the second electric cylinder 63, respectively. The conveying channel 5 can be tilted to different postures depending on the extension of the push rod ends of the first electric cylinder 64 and the second electric cylinder 63.

[0023] Please see Figure 3 The conveying channel 5 includes an upper inclined section 52 and a lower inclined section 51 that are connected and installed together. The angle between the upper inclined section 52 and the bottom surface of the material tray 1 is smaller than the angle between the lower inclined section 51 and the bottom surface of the material tray 1. The smaller inclination angle of the upper inclined section 52 is more conducive to forming a smooth channel with the bottom surface of the material tray 1, so that the fertilizer can enter more smoothly from the input end of the upper inclined section 52. The lower inclined section 51 with a larger inclination angle has enough space between it and the edge of the material tray 1, so that it will not contact the material tray 1 during swing adjustment, thus avoiding work interference.

[0024] How driver component 6 works: In the first configuration, the push rods of the second electric cylinder 63 and the first electric cylinder 64 extend and retract simultaneously, which can lift or lower the conveying channel 5, thereby adjusting the distance between the scraper 3 and the bottom surface of the material tray 1 and changing the particle size of the produced fertilizer.

[0025] In the second configuration, when the push rod end of the second electric cylinder 63 extends and the push rod end of the first electric cylinder 64 retracts, the input end of the upper inclined section 52 separates from the bottom surface of the material tray 1. At the same time, the tilt angle of the scraper 3 can be changed to adapt to the crushing intensity required by different fertilizers, and the particles will not enter the upper inclined section 52.

[0026] In the third form, when the push rod end of the second electric cylinder 63 retracts and the push rod end of the first electric cylinder 64 extends, the input end of the upper inclined section 52 abuts against the bottom surface of the material tray 1. As the material tray 1 rotates counterclockwise, the fertilizer particles can enter the upper inclined section 52 and eventually be discharged along the lower inclined section 51, which is the discharge stage.

[0027] In addition, the three-point rotation structure formed by the two rotating seats 61 and the bearing seat 62 can be adapted to adjust the tilt angle of the conveying channel 5 and the second electric cylinder 63, avoiding restricted movement.

[0028] The upper end of the scraper 3 is fixedly assembled with the upper inclined section 52. The angle between the scraper 3 and the bottom surface of the material tray 1 is an acute angle. The scraper 3 in this inclined posture can more smoothly crush the fertilizer.

[0029] Please see Figure 4The specific structure of the spray assembly 8: The spray assembly 8 includes a bend 81, branch pipes 82, and nozzles 83. The bend 81 is fixedly assembled with the housing 9. At least two pairs of branch pipes 82 are installed along the bend 81. The nozzles 83 are evenly installed on the branch pipes 82. The nozzles 83 pass through the housing 9 and extend into the material tray 1. When in use, the bend 81 is connected to an external water tank with a pump, which can spray high-pressure water through each nozzle 83. The arrangement of multiple pairs of branch pipes 82 can increase the spraying area. Compared with the traditional single-point spraying method, the spraying range is larger and more uniform.

[0030] The working principle of this embodiment: The adjusting base 10, the second electric cylinder 63, the first electric cylinder 64, and the geared motor 11, etc., are electrically connected to the external electrical cabinet. The electrical cabinet is an existing device with an operation panel, controller, etc., used to coordinate the work of each component.

[0031] During granulation, the tilt angle of the conveying channel 5 is controlled by the drive component 6, so that the upper inclined section 52 is lifted, the scraper 3 is in the crushing position, the reduction motor 11 rotates the material tray 1 at a uniform speed, the fertilizer is fed into the material tray 1 through the conveyor aligned with the feed port 4 and rotates counterclockwise, at the same time the spray component 8 sprays water mist evenly, the fertilizer gradually forms granules after passing through the water mist agglomeration and the scraper 3 crushing.

[0032] After granulation is completed, the spraying assembly 8 stops spraying, the material tray 1 continues to rotate, and the drive assembly 6 changes the inclination angle of the conveying channel 5 so that the upper inclined section 52 abuts against the bottom surface of the material tray 1. The granules that continue to rotate will be discharged along the upper inclined section 52 and the lower inclined section 51 to be collected in the externally placed turnover box. After all the granules are discharged, the machine can be reset and stopped.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
