Technical Field
[0001] This utility model relates to the technical field of screening devices for raw material systems in chain loop production lines, specifically an adjustable-angle debris screen for chain loop production lines. Background Technology
[0002] In the Chainlink Global Group production line, raw materials need to be ground by a high-pressure roller mill, allowing particles with a diameter ≤20mm to pass through. A debris screen is a crucial component for screening and separating materials. However, existing debris screens use a fixed I-beam support structure with a fixed and excessively high inclination angle. This results in a short residence time of the raw material on the screen surface. Some qualified raw materials ≤20mm fail to pass through the 20mm roller gap in time and mistakenly enter the debris funnel, causing low screening efficiency (utilization rate of only about 85%) and requiring secondary processing of the debris-containing material. This prolongs processing time, increases the workload of operators, and raises investment costs. Furthermore, the fixed angle cannot adapt to changes in raw material particle size and moisture content, requiring frequent shutdowns for adjustments, affecting production continuity. Its lack of flexibility means that in the Chainlink Global Group production line, the debris screen may be subject to various dynamic loads, such as material impact and vibration. The fixed support structure may not be able to adapt well to these dynamic changes, potentially leading to fatigue damage or deformation after long-term use. In addition, fixed support structures may also cause inconvenience in terms of installation and maintenance. For example, adjusting the tension of the screen or replacing worn parts may require more disassembly and reinstallation work, increasing long-term maintenance and operating costs.
[0003] Therefore, based on the aforementioned problems in reality, it is necessary to design a debris sieve structure with dynamically adjustable angle. Utility Model Content
[0004] The purpose of this utility model is to provide an adjustable-angle impurity screen with a more reasonable structural design, easy processing, low processing cost, and adjustable angle that can be adjusted at any time according to the size and humidity of the raw materials. The adjustment time is short and will not cause production downtime. It eliminates the failure of high-pressure roller mill pin damage, improves the stability of the pelletizing system and the quality of the finished pellets, is easy to maintain, and has good stability and high reliability. It also features advanced technology, long service life, strong adaptability and wide application in chain loop production lines.
[0005] This utility model discloses an adjustable-angle debris screen for a chain loop production line, comprising a frame, multiple screen rollers uniformly fixedly installed on the surface of the frame, a screen body fixedly installed on the surface of the screen rollers, a feed port fixedly installed on the surface of the screen body, and a discharge port fixedly installed on the bottom surface of the frame; a screen roller drive motor is fixedly connected to one side of the screen rollers, and multiple support legs are fixedly installed on the bottom surface of the frame; the frame and screen body are inclined.
[0006] The included angle between the frame, the screen body and the ground is 13°-15°.
[0007] The number of outriggers is four, with two outriggers forming a group, and they are respectively located on the same side. One outrigger on one side includes a lower plate and an upper plate of the machine head adjustment short hinge hole, which are movably connected. The other outrigger on the other side also includes a lower plate and an upper plate of the machine head adjustment short hinge hole, which are movably connected.
[0008] The lower and upper plates of the machine head adjustment short hinge hole are movably connected. Therefore, by adjusting the positions of these two plates, the angle between the frame, screen body, and horizontal plane can be adjusted at any time according to the size and moisture content of the raw materials being screened. This makes operation convenient, time-saving, and labor-saving, without causing production downtime, ensuring product quality and the normal operation of the production line.
[0009] The lower plate of the machine head adjustment short hinge hole includes a first supporting I-beam steel. Two first connecting plates are fixedly connected to the inner wall of the first supporting I-beam steel. The two first connecting plates are symmetrically arranged along the center of the first supporting I-beam steel. Fixing holes are provided on the first connecting plates. A first mounting plate is fixedly connected to the bottom surface of the first supporting I-beam steel. The upper plate of the machine head adjustment short hinge hole includes a second supporting I-beam steel. Two second connecting plates are fixedly connected to the inner wall of the second supporting I-beam steel. Multiple evenly arranged first mounting holes are provided on the side wall of the second connecting plates. The second supporting I-beam steel is fixedly installed on the bottom surface of the frame. Bolts and nuts are fixedly installed through the through fixing holes and the first mounting holes to fix the first connecting plates and the second connecting plates.
[0010] The second supporting I-beam is fixedly connected to the bottom of the frame via a flange. The first mounting plate is fixedly connected to the bottom of the first supporting I-beam, allowing it to be securely installed on the ground or other operating surface. Two first connecting plates are provided, each with a fixing hole. The second connecting plate has multiple vertically evenly distributed first mounting holes on its side wall. Because the angle between the frame, screen body, and ground is 13°-15°, and they are inclined, adjustments to the angle between them can be made. The screen can be adjusted by overlapping one of the first mounting holes with a fixed hole. By adjusting the height between the second support I-beam and the first support I-beam, the angle between the frame, screen body and the ground can be adjusted. The angle between the frame, screen body and the horizontal plane can be adjusted at any time according to the size and humidity of the raw material being screened. The adjustment range is wide and the operation is convenient. The impurity screen has strong stability. The appropriate angle of the impurity screen can ensure that 100% of the qualified raw material passes through the gap of the impurity screen rollers without raw material overflow or material carried in the impurities. It eliminates the failure of high pressure roller mill pin damage, and at the same time improves the stability of the pelletizing system and the quality of the finished pellets.
[0011] The upper plate of the machine head adjustment short hinge hole includes a third supporting I-beam steel. A first connecting part is fixedly connected to the middle position of the third supporting I-beam steel. A second mounting hole is provided on the side wall of the first connecting part. The third supporting I-beam steel is fixedly installed on the bottom surface of the machine frame. The lower plate of the machine head adjustment short hinge hole includes a fourth supporting I-beam steel. Two second connecting parts are fixedly connected to the inner wall of the fourth supporting I-beam steel. The two second connecting parts are symmetrically arranged along the center of the fourth supporting I-beam steel. A third mounting hole is provided on the side wall of the second connecting part. Bolts and nuts are fixedly installed through the second mounting hole and the third mounting hole to fix the first connecting part and the second connecting part.

[0012] The third supporting I-beam is fixedly installed on the bottom of the frame via a flange. The fourth supporting I-beam is fixedly installed on the ground or other operating surface via a second mounting plate, ensuring a stable and reliable installation. A first connecting part with a second mounting hole and a second connecting part with a third mounting hole are connected by bolts and nuts, creating a hinge between the first and second connecting parts. This allows for adjustment of the angle between the frame, screen body, and horizontal plane based on the size and moisture content of the raw material being screened. This adjustment works in conjunction with the angle adjustment between the lower and upper plates of the short hinge hole at the machine head, resulting in a more precise and widely applicable angle.
[0013] The beneficial effects of this utility model are: 1) The lower plate and upper plate of the machine head adjusting short hinge hole are movably connected. Therefore, by adjusting the positions of the lower and upper plates of the machine head adjusting short hinge hole, the angle between the frame, screen body and the horizontal plane can be adjusted at any time according to the size and humidity of the raw material being screened. This makes operation convenient, time-saving, and labor-saving, and will not cause production downtime, ensuring product quality and the normal operation of the production line.
[0014] 2) The second supporting I-beam is fixedly connected to the bottom surface of the frame via a flange.

The first mounting plate allows the first supporting I-beam to be securely installed on the ground or other operating surface, ensuring stability and reliability. Two first connecting plates are provided, each with a fixing hole. The second connecting plate has multiple vertically evenly distributed first mounting holes on its side wall. Since the angle between the frame, screen body, and ground is 13°-15°, and the structure is inclined, adjustments to the angle between the frame, screen body, and ground can be made as needed. At the same time, one of the first mounting holes can overlap with a fixed hole. By adjusting the height between the second support I-beam and the first support I-beam, the angle between the frame, the screen body and the ground can be adjusted. The angle between the frame, the screen body and the horizontal plane can be adjusted at any time according to the size and humidity of the raw material being screened. The adjustment range is wide and the operation is convenient. The impurity screen has strong stability. The appropriate angle of the impurity screen can ensure that 100% of the qualified raw material passes through the impurity screen roller gap, without raw material overflow or material carried in the impurities. It eliminates the failure of high pressure roller mill pin damage, and at the same time improves the stability of the pelletizing system and the quality of the finished pellets.
[0015] 3) The third supporting I-beam is fixedly installed on the bottom of the frame via a flange. The fourth supporting I-beam is fixedly installed on the ground or other operating surface via the second mounting plate, ensuring a stable and reliable installation. The first connecting part has a second mounting hole, and the second connecting part has a third mounting hole.

[0025] Instructions for use: 1) Fabricate the first connecting plate 101 and the second connecting plate 202. The plates are made of 16mm thick steel plate. The first connecting plate 101 is 290mm wide, 400mm long, and 16mm thick; the fixing hole 104 has a diameter of φ40mm; the second connecting plate 202 is 290mm wide, 300mm high, and 16mm thick; there are six first mounting holes 203, each with a diameter of φ40mm. 2) The first connecting part 402 and the second connecting part 303 are 16mm thick, with a bottom width of 240mm and a bottom-to-top hole diameter of 150mm. The third mounting hole 302 has a diameter of φ40mm. 3) Cut off 500mm of the middle of the two 300mm supporting I-beams 201 at the front end of the debris screen using gas cutting. Align the first connecting plates 101 and the second connecting plates 202 at both ends of the debris screen head and weld them to the upper and lower ends of the cut second supporting I-beams 201. The spacing between the second connecting plates 202 is 30mm, and the spacing between the first connecting plates 101 is 65mm. 4) Weld the lower plate 3 and the upper plate 4 of the adjusting short hinge hole of the machine head using the same method. 5) When it is necessary to adjust the angle between the frame 6, the screen body 5 and the ground, one of the multiple first mounting holes 203 can be overlapped with a fixing hole 104.

This coordinates with the adjustment of the angle between the lower plate 1 and the upper plate 2 of the short hinge hole of the head adjustment, thereby adjusting to a more suitable and precise angle, making the application range wider. 7) After the angle is adjusted, the material to be screened can be added into the screen body 5 through the feeding port 9. The screen roller drive motor 7 is started to screen the material in the screen body 5. The remaining material after screening flows out through the discharge port 10. With the appropriate angle of the screen body 5, 100% of the qualified raw material can pass through the gap of the impurity screen roller, with no raw material overflow or material carried in the impurities. This eliminates the failure of the high-pressure roller mill pin damage, and at the same time improves the stability of the pelletizing system and the quality of the finished pellets.
