Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, and in particular to a granulation device for solid fertilizer processing. Background Technology

[0002] In fertilizer production, the granulation process compresses powdered raw materials into granules for easier subsequent use. However, raw materials often adhere to the surface of the rollers in traditional granulation equipment, requiring frequent machine shutdowns for cleaning, leading to production interruptions and reduced efficiency. While some devices can clean simultaneously, they rely on additional drive systems, increasing operational complexity and cost. Furthermore, foreign objects or large particles mixed in the raw materials can easily clog the molding dies, increasing equipment failure rates and impacting production continuity and economic efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in cleaning rolling mill rolls, and to propose a granulation device for solid fertilizer processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A granulation device for solid fertilizer processing includes a machine body and a top shell hinged to the top of the machine body, wherein a discharge end is provided on one side of the machine body; Two parallel rollers are rotatably mounted inside the machine body via bearings; Two mounting brackets are slidably fitted into longitudinal grooves on the inner walls of both sides of the machine body. The mounting brackets are provided with brushes on the side facing the rolls, and the bristles of the brushes are in contact with the surface of the rolls. The frame is slidably inserted into the feed inlet of the top shell, and a screen is fixed inside it, with one side of the frame extending to the outside of the top shell. The two ends of the roll are fixedly connected to connecting shafts, and two corrugated rings are fixedly sleeved on the outer walls of the two connecting shafts on one side. The outer walls of the corrugated rings are periodic corrugated surfaces. The extension ends of the mounting bracket and the frame are each connected to two connecting brackets. The ends of the connecting brackets are rotatably fitted with ball bearings, which roll into contact with the wavy surface of the wave ring. When the wave ring rotates with the roller, its wave surface pushes the ball bearings to reciprocate laterally. The connecting frame drives the brush to periodically clean the roller surface, while simultaneously driving the screen to vibrate and screen the raw materials.

[0005] In one possible design, meshing gears are fixedly fitted onto the outer walls of the two connecting shafts on the other side, and a motor is mounted on the outer wall of the machine body. The motor is connected to the connecting shaft of one of the rolls via a coupling.

[0006] In one possible design, the outer wall of the fuselage is fixed to the first protective shell by bolts, and the gear is located inside the first protective shell.

[0007] In one possible design, a feed hopper is installed at the feed inlet of the top shell.

[0008] In one possible design, the hinged end of the body and the top shell is provided with a latch, and a handle is fixed to the outer wall of the top shell.

[0009] In one possible design, the second protective shell is fixed to the other side of the fuselage by bolts, and the wave ring and ball bearings are located inside the second protective shell.

[0010] In one possible design, a guide plate is fixedly inclined on the inner wall of the top shell, and the lower end of the guide plate extends directly above the meshing area of ​​the two rolls.

[0011] In this application, during actual use, the rollers are driven by a motor via a connecting shaft and meshing gears to achieve synchronous, opposite rotation of the two rollers. The raw material enters between the two rollers through a feed hopper, and then high pressure is applied by the two relatively rotating rollers, causing the raw material to be shaped into granules in the mold recess, which can then be discharged through the discharge end. When the rollers rotate, the connecting shaft will drive the corrugated ring to rotate as well. When the corrugated ring rotates, the balls that are in contact with its surface will move laterally back and forth. Then, the connecting frame can drive the corresponding mounting frame and frame to move. The movement of the mounting frame will drive the brush to move, thereby sweeping away the raw material remaining on the roller surface, while the movement of the frame will drive the internal screen to move, thereby helping to screen the raw material and preventing foreign objects from entering the device.

[0012] In this utility model, the granulation device for solid fertilizer processing can convert the rotational motion of the roller into the reciprocating cleaning action of the brush and screen through the corrugated ring and ball bearings, so that the roller surface can be cleaned in real time and the raw materials can be screened without the need for an additional power source. In this utility model, the granulation device for solid fertilizer processing adopts a detachable design for the connecting frame, which facilitates the opening and closing of the top shell, thereby making it easier for subsequent staff to perform maintenance and other operations on the inside of the device. In this invention, the driving force of the roller can be converted into the driving force of the screen and brush during use, so that the corresponding cleaning and screening operations can be achieved without the need for an additional power source. This not only improves production quality, but also has a simple structure that is easy to use in practice. Attached Figure Description

On one side, the outer wall of the two connecting shafts 11 is fixedly fitted with a wave ring 10. The outer wall of the wave ring 10 has a periodically undulating wave surface structure.

[0018] The inner walls of both sides of the machine body 1 are symmetrically provided with longitudinal grooves, and the mounting bracket 12 is slidably embedded in the grooves. A brush 16 is fixed to the side of the mounting bracket 12 near the roller 15, and the bristles of the brush 16 are in contact with the surface of the roller 15. A frame 8 is slidably inserted at the feed inlet of the top shell 2. A screen is fixed inside the frame 8, and one end of both the frame 8 and the mounting bracket 12 extends to the outside of the top shell 2.

[0019] refer to Figure 1 The motor 5 is fixedly mounted on the outer wall of the machine body 1 via a motor bracket. The end of the connecting shaft 11 of one of the rollers 15 is connected to the output shaft of the motor 5 via a coupling. Specifically, the outer walls of the two connecting shafts 11 on one side are fixedly fitted with meshing gears. The outer wall of the machine body 1 is fixed with a first protective shell 4 by bolts, and both gears are located inside the first protective shell 4.

[0020] refer to Figure 3-4The extension ends of the mounting bracket 12 and the frame 8 are each connected to two connecting brackets 9.

An inclined guide plate 14 is fixed to the inner wall of the top shell 2 by welding. The lower end of the guide plate 14 extends directly above the meshing point of the two rollers 15.

[0021] Working process: After the motor 5 is started, the two rollers 15 are driven to rotate synchronously in opposite directions through the gear. The raw material falls into the top shell 2 through the feed hopper 3 and slides into the meshing area of ​​the two rollers 15 along the guide plate 14. Under high pressure, it is formed into granules and discharged from the discharge end 7. When the roller 15 rotates, it drives the wave ring 10 to rotate synchronously through the connecting shaft 11. The wave surface forces the ball 13 to produce a lateral reciprocating motion. The connecting frame 9 drives the mounting frame 12 to drive the brush 16 to periodically clean the surface of the roller 15. At the same time, the frame 8 drives the screen to vibrate to achieve raw material screening.
