[0002] Roller granulator is a kind of molding machine that can make materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields.

[0003] In application number: CN201922038086.8, a roller granulator for fertilizer production is disclosed. The device can collect the extruded material through a dividing hopper, rotate the material under the gravity of the material through the guide plate, and transport the material out through the discharge hole, thereby reducing the adhesion of the material and improving the working efficiency of the granulator.

[0004] However, the device lacks a basic screening mechanism after the fertilizer granulation is completed, which may easily cause some fertilizer raw materials that have not formed into granules to fall into the dividing hopper, causing the discharge hole of the dividing hopper to be blocked. In addition, the feed funnel of the device is in an open state, and foreign objects may easily fall into it when the staff add materials. It may be dangerous to directly reach out to take the foreign objects.

[0005] For this reason, we propose a roller granulator for fertilizer production. Utility Model Content

[0006] The main purpose of the utility model is to provide a roller granulator for fertilizer production. By arranging a second filter screen inside the processing box, the fertilizer particles rolled down by the granulation mechanism can be basically screened, thereby preventing some fertilizer raw materials that have not formed into granules from falling into the distribution hopper. At the same time, the first filter screen arranged on the feed funnel can effectively prevent foreign matter from falling into the processing box during the feeding process, so that the foreign matter can be removed in time without causing danger, and the problems in the background technology can be effectively solved.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A roller granulator for fertilizer production, comprising a processing box, a feeding funnel is arranged at the top of the processing box, a first filter screen is mounted inside the feeding funnel, the top of the feeding funnel is fixedly connected to the bottom of an anti-overflow plate, and the anti-overflow plate is arranged in an annular structure;

[0010] Furthermore, a support plate is fixedly connected to one side of the processing box just below the first discharge port, and the support plate is used for placing the collection box.

[0011] Furthermore, a material distribution hopper is provided inside the processing box directly below the second filter screen, one side of the material distribution hopper is fixedly connected to one end of a receiving plate, and the other end of the receiving plate is fixedly connected to an inner wall of one side of the processing box close to the support plate.

[0012] Furthermore, a second discharge port is provided at the bottom center of the processing box, and a valve is sleeved on the outer side of the second discharge port.

[0013] Furthermore, the bottom end of the processing box and the bottom end of the support plate are fixedly connected to the top end of the movable rod, the bottom end of the movable rod is movably plugged into the top end of the sleeve, and the movable rod and the sleeve are provided with multiple locations.

[0014] Furthermore, a motor is fixedly mounted on the upper part of the processing box adjacent to the vibrating machine, and an output end of the motor passes through one side of the processing box and is fixedly connected to a running gear of the granulating mechanism.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a roller granulator for fertilizer production comprises a processing box 1, a feeding funnel 7 is arranged at the top of the processing box 1, a first filter screen 5 is mounted inside the feeding funnel 7, the top of the feeding funnel 7 is fixedly connected to the bottom of an anti-overflow plate 6, the anti-overflow plate 6 is arranged in an annular structure, and the mesh of the first filter screen 5 is slightly larger to allow the fertilizer raw material to pass through the mesh and fall into the processing box 1;

[0022] A granulation mechanism 12 is provided inside the processing box 1, and a second filter screen 14 is provided directly below the granulation mechanism 12. The mesh of the second filter screen 14 is slightly larger than the diameter of the fertilizer particles produced by the granulation mechanism 12. The second filter screen 14 is arranged to be tilted downward. A first discharge port 8 is provided on one side of the processing box 1. The first discharge port 8 is located above the end of the second filter screen 14 tilted downward. A vibrator 13 is fixedly installed on the upper part of the side of the processing box 1 away from the first discharge port 8. The vibrator 13 can vibrate the fertilizer raw materials on the first filter screen 5 and the fertilizer particles on the second filter screen 14, thereby accelerating the feeding speed of the fertilizer raw materials and the screening speed of the fertilizer particles.

[0023] A support plate 10 is fixedly connected to one side of the processing box 1, located just below the first discharge port 8, and the support plate 10 is used to place the collection box 9; a distribution hopper 15 is provided inside the processing box 1, located just below the second filter screen 14, and one side of the distribution hopper 15 is fixedly connected to one end of a receiving plate 11, and the other end of the receiving plate 11 is fixedly connected to the inner wall of the processing box 1 near the support plate 10, and the receiving plate 11 can catch the fertilizer particles that fall from the inclined end of the second filter screen 14 and guide them into the distribution hopper 15; a second discharge port 16 is provided at the bottom center of the processing box 1, and a valve 17 is sleeved on the outer side of the second discharge port 16;

[0024] The bottom end of the processing box 1 and the bottom end of the support plate 10 are fixedly connected to the top end of the movable rod 3. The bottom end of the movable rod 3 is movably inserted into the top end of the sleeve 4. The movable rod 3 and the sleeve 4 are provided with multiple locations, and a spring is provided inside the sleeve 4. The processing box 1 is located on the upper part of a side adjacent to the vibrator 13 and a motor 2 is fixedly installed. The output end of the motor 2 passes through one side of the processing box 1 and is fixedly connected to the running gear of the granulation mechanism 12. The working principles of the granulation mechanism 12 and the distribution hopper 15 are specifically described in the existing mature technology mentioned in the background technology.

[0025] It should be noted that the utility model is a roller granulator for fertilizer production. First, the motor 2 is started by an external power supply, and the motor 2 drives the granulation mechanism 12 to operate. Then, the fertilizer raw materials are poured in from directly above the feed hopper 7. The first filter screen 5 is set to prevent foreign matter from falling during the feeding process. Even if foreign matter falls, it will be intercepted by the first filter screen 5, and the staff can take it out in time. Then, the entire processing box 1 is vibrated by turning on the vibrator 13 to accelerate the fertilizer raw materials from the feed funnel 7 into the processing box 1. After the fertilizer raw materials are rolled by the granulation mechanism 12, they will become several particles and fall onto the second filter screen 14. Some fertilizer particles of normal size will pass through the second filter screen 14 and fall into the distribution hopper 15. After being processed by the distribution hopper 15, they can be discharged from the second discharge port 16. Some fertilizer raw materials with irregular shapes will be discharged from the first discharge port 8 along with the second filter screen 14 set obliquely downward and fall into the collection box 9, ready to be poured into the feed funnel 7 again for re-granulation.
