Technical Field

[0001] This utility model relates to the field of pellet mill waste recycling technology, specifically a pellet mill waste recycling device. Background Technology

[0002] In industrial production, granulators are widely used in pharmaceuticals, food, chemicals, and many other industries as an important piece of equipment. Their function is to process powdered materials into granules of a specific shape and size. However, waste is inevitably generated during the granulation process. This waste not only wastes raw materials and increases production costs, but also pollutes the environment if discharged indiscriminately. Traditional waste disposal methods mostly involve direct discarding or simple collection followed by centralized processing, failing to achieve the desired crushing and recycling of the waste.

[0003] According to the patent application published on the Internet, a waste recycling device for a granulator (authorization announcement number: CN213770355U) is described as including "machine body, discharge port, and feed pipe" to achieve recycling.

This device is equipped with multiple collection boxes for collection during use, but it cannot crush the waste, which affects the effect of subsequent processing and increases the processing steps. In addition, dust is generated during the recycling process, and this device cannot treat the dust generated. The dust emitted into the air will have an impact on the environment. Therefore, this device needs to be improved. Utility Model Content

[0015] Compared with the prior art, this utility model provides a waste recycling device for a pellet mill, which has the following beneficial effects:

[0016] 1. The waste recycling device of this pellet mill, through a recycling mechanism located on the right side of the pellet mill body, can effectively collect waste discharged from the discharge pipe. A servo motor drives a rotating rod and a crushing roller, which mesh with the crushing teeth to crush the waste, facilitating subsequent recycling and improving waste recycling efficiency while reducing resource waste. During crushing and recycling, a filter plate is installed in the dust collection box. Combined with a fan, it can adsorb and filter fine impurities such as dust in the waste. When the cylinder and second cleaning brush in the filtering mechanism are working, they drive the connecting shaft and connecting frame to move to the right outside the fixed rod, causing the spring to deform. This allows the connecting frame to move the connecting rod and the first cleaning brush, cleaning the dust accumulated on the top of the filter plate under the action of the first cleaning brush, preventing blockage during filtration and affecting the filtration effect. When the second cleaning brush releases its pressure on the connecting shaft, the spring returns to its original position, allowing the first cleaning brush to return to its original position. The filter plate is fixed by a first limit pin, facilitating subsequent installation, disassembly, and cleaning of filtered impurities.

[0017] 2. The waste recycling device of this granulator, through the set filtration mechanism, after the waste generated by the granulator body is crushed under the action of the crushing box, the waste will enter the connecting box. Under the action of the screening plate inside the connecting box, the crushed waste can be further screened, separating the recyclable materials that meet the requirements from the remaining impurities. The cylinder drives the second cleaning brush to clean the screening plate, ensuring a smooth screening process, preventing waste from clogging the screening plate, and improving screening efficiency and quality. When the second cleaning brush moves to the right to half position of the screening plate, it will contact the left side of the connecting shaft, which can drive the connecting shaft to move to the right, so that the first cleaning brush cleans the filter plate, realizing a linkage effect. The screening plate is fixed by the second limit pin, which is convenient for installation and disassembly. Attached Figure Description

[0034] The front side of the rotating rod 47 is rotatably connected to the inside of the crushing box 42. The crushing roller 48 and the crushing teeth 49 mesh with each other, which facilitates the crushing of waste materials under the action of the crushing roller 48 and the crushing teeth 49. The bottom of the first cleaning brush 494 is in contact with the top of the filter plate 491.

[0035] Example 2

[0036] Please see Figure 1-8 Furthermore, based on Embodiment 1, the filtration mechanism 5 includes a connecting box 51, which is fixedly connected to the bottom of the crushing box 42. A screening plate 54 is slidably connected inside the connecting box 51, and a second limiting pin 55 is threadedly connected inside the screening plate 54. A cylinder 52 is fixedly connected to the right side of the connecting box 51, and a second cleaning brush 53 is fixedly connected to the left side of the cylinder 52. The second cleaning brush 53 is located on the top of the screening plate 54. A protective box 56 is fixedly connected to the bottom of the connecting box 51, and the protective box 56 is fixedly connected to the top of the base 2. A storage box 57 is slidably connected inside the protective box 56.

[0037] The right side of the second cleaning brush 53 is in contact with the left side of the connecting shaft 496, and the bottom of the second cleaning brush 53 is in contact with the top of the screening plate 54. The connecting box 51 has a groove with the same movement trajectory as the connecting shaft 496. The connecting shaft 496 is slidably connected in the groove, and the second limiting pin 55 passes through the inside of the connecting box 51, so as to facilitate the screening of the crushed waste material under the action of the screening plate 54.

[0038] In actual operation, when this device is used, the waste generated by the pellet mill body 1 will enter the crushing box 42 through the discharge pipe 3. When it enters the crushing box 42, the servo motor 43 drives the rotating rod 47 and the crushing roller 48 to rotate, and they mesh with the crushing teeth 49 to crush the waste, which is convenient for subsequent recycling and improves the efficiency of waste recycling and reduces resource waste. During the crushing and recycling process, the dust collection box 44 is equipped with a filter plate 491, which, together with the fan 495, can adsorb and filter the dust and other fine impurities in the waste. The filtered dust will be discharged through the top of the dust collection box 44.

[0039] After the waste material generated by the granulator body 1 is crushed by the crushing box 42, the waste material enters the connecting box 51. Under the action of the screening plate 54 inside the connecting box 51, the crushed waste material can be further screened to separate the recyclable materials that meet the requirements from the remaining impurities. The screened waste material enters the storage box 57 through the protective box 56 for storage. Impurities continue to remain on the top of the screening plate 54. The cylinder 52 drives the second cleaning brush 53 to clean the screening plate 54, ensuring a smooth screening process, preventing waste material from clogging the screening plate 54, improving screening efficiency and quality. And when the second cleaning brush 53 moves to the right... When the filter plate 54 is moved to half position, it will come into contact with the left side of the connecting shaft 496, which will drive the connecting shaft 496 to move to the right. This will cause the connecting frame 45 to move the connecting rod 492 and the first cleaning brush 494, and the connecting frame 45 to slide around the fixed rod 46, causing the spring 497 to deform. Under the action of the first cleaning brush 494, the dust accumulated on the top of the filter plate 491 can be cleaned, avoiding blockage during the filtration process and affecting the filtration effect. When the second cleaning brush 53 releases the pressure on the connecting shaft 496, the spring 497 returns to its original position, which will also reset the first cleaning brush 494.

[0040] The filter plate 491 and the screening plate 54 are fixed by the first limiting pin 493 and the second limiting pin 55 respectively. When it is necessary to replace or remove the filter plate 491 and the screening plate 54 for cleaning, simply remove the first limiting pin 493 and the second limiting pin 55.
