Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulator technology, specifically a granulator with a screening function. Background Technology
[0002] Pelleted feed is a nutritionally complete and stable feed that does not easily break down in water, does not easily pollute water bodies, and is easily digested and absorbed, making it popular among farmers. The manufacturing process of pelleted feed requires a pellet mill, which is a feed processing machine that directly presses crushed materials such as corn, soybean meal, straw, grass, and rice husks into pellets.
[0003] Current pellet mills struggle to precisely control pellet size during production, inevitably resulting in uneven pellet size. Directly packaging and selling these pellets with feed pellets significantly impacts the quality of the finished product. Furthermore, the pellets contain high moisture content, are highly sticky, and prone to clumping, further affecting product quality. Therefore, there is an urgent need for a pellet mill with screening capabilities to address these issues. Utility Model Content

[0031] In this embodiment, in actual use, a vibration motor 15 is installed at the bottom of the screening box 4, the end of the spring 5 away from the screening box 4 is connected to the housing 1, the baffle plate 6 is set at an inclination, the vibration motor 15 drives the screening box 4 to vibrate, so that the particles move on the screening screen 7, the particles that meet the particle size requirements fall into the screening box 4 through the screening screen 7, and the particles that do not meet the requirements slide into the guide box 9.
[0032] Specifically, refer to Figure 2 A hot air blower 8 is fixedly connected to the side wall of the shell 1, and an air outlet 18 is opened on the front of the shell 1. A screen is fixedly connected inside the screening box 4. The hot air blower 8 is connected to the inside of the screening box 4 and is equipped with a screen. The screen effectively intercepts feed particles. The hot air blower 8 and the air outlet 18 can dry the particles during the pelleting and screening process to prevent the particles from clumping due to moisture or affecting the quality of subsequent processing.
[0033] Specifically, refer to Figure 3 A recycling shell 10 is fixedly connected to the back of the shell 1, a recycling pipe 11 is fixedly connected to the outside of the recycling shell 10, and a conveying assembly is provided inside the recycling shell 10. The conveying assembly includes a drive motor 12 fixedly installed at the bottom of the recycling shell 10, and a conveying auger 13 is fixedly connected to the output shaft of the drive motor 12.
[0034] In this embodiment, in actual use, the inside of the feed box 9 is provided with a recycling port 14 that communicates with the recycling shell 10. The end of the recycling pipe 11 away from the recycling shell 10 is fixedly connected to the pellet mill 2. The recycling port 14 of the feed box 9 is connected to the recycling shell 10 to ensure that the particles can smoothly enter the inside of the recycling shell 10. The design of the recycling shell 10 and the conveying assembly is to drive the conveying auger 13 to rotate through the drive motor 12 to convey the particles. The particles that do not meet the requirements are conveyed to the feed funnel of the pellet mill 2 through the recycling pipe 11, realizing the recycling and reuse of particles that do not meet the requirements, avoiding waste and improving the material utilization rate.
[0035] In this embodiment, in actual use, a guide block 16 is fixedly connected to the inner bottom wall of the screening box 4, and a discharge plate 17 extending to the outside of the shell 1 is fixedly connected to the outside of the screening box 4.

[0036] Working principle:
[0037] First: The pellet mill 2 turns the feed raw materials into pellets, and the pellets are conveyed into the shell 1 through the feed cylinder 20. The pellets fall onto the screen 7, and the screen box 4 is vibrated by the vibration motor 15, so that the pellets move on the screen 7. Particles that meet the particle size requirements fall into the screen box 4 through the screen 7, and particles that do not meet the requirements slide into the guide box 9.
[0038] Then: The hot air blower 8 and the air outlet 18 are set up to dry the granules during the granulation and screening process. The granules are guided by the baffle plate 6 and the guide block 16 and discharged through the discharge plate 17. The granules in the guide box 9 enter the interior of the recycling shell 10 through the recycling port 14. The conveying auger 13 is driven by the drive motor 12 to rotate and transport the granules. The granules that do not meet the requirements are transported to the feed funnel of the granulator 2 through the recycling pipe 11. This realizes the recycling and reuse of granules that do not meet the requirements, avoids waste and improves the material utilization rate.
