Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to an auxiliary device for fertilizer granulation. Background Technology

[0002] A fertilizer roller extrusion granulator is a device used to process fertilizer raw materials into granular fertilizer. Its principle involves a pair of relatively rotating rollers with grooves of different shapes and sizes machined on their surfaces. When fertilizer raw materials enter between the two rollers, they are forced into the grooves by the rollers' squeezing action, forming granules with a specific shape and strength under pressure. As the rollers rotate, the granules detach from the roller surface, completing the granulation process.

[0003] However, during the extrusion granulation process of fertilizer raw materials by the two rollers, residual fertilizer raw materials easily adhere to the surfaces and grooves of the rollers and do not fall off. This residual fertilizer raw material affects the subsequent granulation effect, resulting in irregular granule shapes and uneven sizes. Therefore, we propose an auxiliary device for fertilizer granulation. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for fertilizer granulation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for fertilizer granulation, comprising a granulator body, a roller frame fixedly installed on the upper end of the granulator body, and extrusion rollers symmetrically rotatably arranged inside the roller frame. Support plates are symmetrically fixedly installed on the bottom inner side of the roller frame. Brushes are fixedly connected to the upper ends of both support plates. The two brushes are respectively attached to the bottom of the two extrusion rollers. Support columns are elastically installed on both side walls of the roller frame via elastic components. A set of striking columns is fixedly connected to the outer walls of both support columns. The ends of the two sets of striking columns away from the support columns are respectively attached to the outer surfaces of the two extrusion rollers. Connecting shafts are fixedly connected to the front ends of both extrusion rollers. Both connecting shafts are rotatably installed through the inner front wall of the roller frame. Rotary wheels are fixedly connected to the front ends of both connecting shafts. A linkage mechanism is provided between the two rotary wheels and the two support columns.

Detailed Implementation

[0020] 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.

[0021] This utility model provides a technical solution: such as Figure 1 - Figure 5 The auxiliary device for fertilizer granulation shown includes a granulator body 7, a roller frame 1 fixedly installed on the upper end of the granulator body 7, and extrusion rollers 2 symmetrically rotated inside the roller frame 1. Support plates 16 are symmetrically fixedly installed on the bottom inner side of the roller frame 1. Brushes 17 are fixedly connected to the upper ends of the two support plates 16. The two brushes 17 are respectively attached to the bottom of the two extrusion rollers 2. Support columns 4 are elastically installed on both sides of the roller frame 1 through elastic components. A set of striking columns 11 is fixedly connected to the outer wall of the two support columns 4. The ends of the two sets of striking columns 11 away from the support columns 4 are respectively attached to the outer surfaces of the two extrusion rollers 2. Connecting shafts 12 are fixedly connected to the front ends of the two extrusion rollers 2. The two connecting shafts 12 are rotatably installed in the front inner wall of the roller frame 1. Rotary wheels 8 are fixedly connected to the front ends of the two connecting shafts 12. A linkage mechanism is provided between the two rotating wheels 8 and the two support columns 4 respectively.

[0022] The elastic component includes four guide posts 10, which are fixedly connected in pairs to the front and rear edges of the side wall of the roller outer frame 1. All four guide posts 10 are movably inserted through the support post 4. Four springs 9 are fixedly connected between the support post 4 and the side wall of the roller outer frame 1. The four springs 9 are slidably sleeved on the outer wall of the four guide posts 10.

[0023] The linkage mechanism includes an L-shaped rod 14 and multiple protrusions 15. One end of the L-shaped rod 14 is fixedly connected to the front end of the support column 4, and the other end of the L-shaped rod 14 is fixedly connected to a cylinder 13. The cylinder 13 is close to the outer ring surface of the rotating wheel 8, and the multiple protrusions 15 are fixedly connected to the outer ring surface of the rotating wheel 8 in a ring array around the center of the rotating wheel 8.

[0024] Both sides of the inner edge of the outer roller frame 1 are fixedly connected with baffle plates 3, and both baffle plates 3 are set at an angle; specifically, by setting baffle plates 3, fertilizer raw materials that have entered the inner side of the outer roller frame 1 are prevented from leaking out from the openings on both sides of the outer roller frame 1.

[0025] The lower corners of the granulator body 7 are all fixedly connected with support legs 5, and the lower ends of the four support legs 5 are all fixedly connected with foot pads 6; specifically, by setting support legs 5 and foot pads 6, the stability of the granulator body 7 is improved.

[0026] Each set of striking columns 11 is arranged in a linear array; specifically, the striking columns 11 arranged in a linear array make the impact on the extrusion roller 2 more uniform.

[0027] Working principle: First, the fertilizer raw material is put into the feed port at the top of the outer roller frame 1 and the granulator body 7 is started. Then, the two extrusion rollers 2 on the inner side of the outer roller frame 1 will rotate relative to each other, and the fertilizer raw material will fall into the position between the two extrusion rollers 2. The fertilizer raw material squeezed by the two extrusion rollers 2 will become granules and fall downwards and finally be discharged from the discharge port of the granulator body 7. This is known existing technology and will not be described in detail.

[0028] It should be noted that during the rotation of the two extrusion rollers 2, they also drive the rotation of their respective connected shafts 12. The two connected shafts 12 drive the rotation of their respective connected rollers 8, and the two rollers 8 can drive the rotation of their respective connected multiple protrusions 15. Figure 4 As you can see, the two cylinders 13 are squeezed by their corresponding protrusions 15 and move away from the rotating wheel 8. The two cylinders 13 will drive their respective connected support columns 4 to move away from the outer frame of the roller. The two support columns 4 will slide outside the corresponding guide column 10 and stretch the corresponding spring 9. The two support columns 4 will also drive the ends of their respective connected set of striking columns 11 to leave the outer surface of the two extrusion rollers 2. When each protrusion 15 rotates to leave the two cylinders 13, under the action of the spring 9, the two support columns 4 and the two sets of striking columns 11 will reset. The ends of the two sets of striking columns 11 will hit the outer surface of the two extrusion rollers 2 respectively, thereby generating vibration. In this way, as the two rotating wheels 8 continue to rotate, the two extrusion rollers 2 can be continuously vibrated. Under the action of vibration, the fertilizer raw materials adhering to the outer surface and groove of the two extrusion rollers 2 can be shaken off.

[0029] It should also be noted that, under the action of the two brushes 17, the residual fertilizer raw materials adhering to the outer surface of the two extrusion rollers 2 can be continuously brushed off, thereby further improving the cleanliness of the outer surface of the two extrusion rollers 2, thus avoiding the residual fertilizer raw materials from affecting the subsequent granule forming effect, and avoiding irregular granule shape and uneven size.
