Description

Technical Field

[0001] This utility model relates to the field of sugar production equipment technology, and in particular to a bearing mounting support structure for a white sugar feeding screw conveyor. Background Technology

[0002] In the drying process of white sugar production, the BMA drum dryer needs to continuously transport the white sugar to be dried into the drum via a feeding screw conveyor. Because this screw conveyor is relatively long to meet the needs of long-distance feeding, the traditional design requires a suspension bearing in the middle of the screw conveyor to support the inner shaft and ensure its rotational stability.

[0003] The existing suspension bearing is located in the middle of the screw conveyor and upstream of the sugar inlet. A large amount of granulated sugar, propelled by the screw blades, is easily drawn into the gap between the suspension bearing and the inner shaft. Inside the bearing, the sugar is subjected to continuous friction and rotational heat, which grinds it into black carbon powder. This carbon powder enters the drum dryer with the material, directly contaminating the granulated sugar product, leading to increased color value and decreased purity, severely impacting product quality. Simultaneously, the drawn-in material accelerates bearing wear, increases equipment failure rate and maintenance costs, and reduces production continuity.

[0004] Therefore, it is necessary to design a bearing mounting support structure for a sugar feeding screw conveyor that can completely separate the bearing from the sugar by changing the bearing installation position, thus preventing the sugar from getting caught between the bearing and the inner shaft and causing contamination. Utility Model Content

[0005] To overcome the problem that granulated sugar is easily caught in the gap between the suspension bearing and the inner shaft, and that the sugar is subjected to continuous friction and rotational heat within the bearing, resulting in it being ground into black carbon powder, which enters the drum dryer with the material and directly contaminates the granulated sugar product. At the same time, the caught material will aggravate bearing wear, increase equipment failure rate and maintenance costs, and reduce production continuity, this utility model provides a bearing mounting support structure for a granulated sugar feeding screw conveyor that can completely separate the bearing from the granulated sugar by changing the bearing installation position, thus preventing the sugar from being caught between the bearing and the inner shaft and causing contamination.

[0006] The technical solution is as follows: A bearing mounting support structure for a white sugar feeding screw conveyor includes a feeding cylinder, a sugar inlet pipe, a sugar outlet pipe, a fixed frame, a motor, screw conveyor blades, a support frame, and a load-bearing component. The sugar inlet pipe is connected to the upper right side of the feeding cylinder, and the sugar outlet pipe is connected to the lower left side of the feeding cylinder. The fixed frame is connected to the right side of the feeding cylinder, and the motor is connected to the fixed frame. The motor and the processor are electrically connected through a control module. An inner shaft is provided on the output shaft of the motor, and screw conveyor blades are connected to the inner shaft. The support frame is connected to the left side of the feeding cylinder, and the support frame is provided with a load-bearing component capable of bearing the load.

[0007] Preferably, the sugar inlet tube has a funnel-shaped structure.

[0008] Preferably, the load-bearing component includes a connecting rod, a mounting sleeve, a first bolt, a bearing, a rotating shaft, and a second bolt. The connecting rod is connected to the inner side of the upper part of the support frame. The mounting sleeve is divided into upper and lower parts, which are hinged to each other. The upper mounting sleeve is connected to the connecting rod. The rear parts of the mounting sleeves are detachably connected by the first bolt. A bearing is snapped into the inside of the mounting sleeve, and a rotating shaft is snapped into the bearing. The rotating shaft is detachably connected to the inner shaft by eight second bolts.

[0009] As a preferred option, double-row self-aligning roller bearings are used.

[0010] Preferably, the first and second bolts are high-strength internal hex bolts (size M16-M20).

[0011] Preferably, the horizontal distance between the bearing axis and the downstream end of the sugar outlet pipe is 200-300mm.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model drives the bearing and rotating shaft to rotate simultaneously through the rotation of the inner shaft. The bearing bears the load, reducing wear. The horizontal distance between the axis of the bearing and the downstream end of the sugar outlet pipe is 200-300mm, ensuring that the white sugar is completely discharged from the sugar outlet pipe before reaching the bearing and cannot enter the bearing area. This achieves the effect of completely separating the bearing from the white sugar by changing the bearing installation position, avoiding the white sugar from getting caught between the bearing and the inner shaft and causing contamination.

[0013] 2. This utility model achieves the effect of conveniently disassembling, replacing, or maintaining the bearing by rotating and loosening the first bolt and removing it, then rotating and opening the mounting sleeve, then rotating and loosening the second bolt and removing it, and then taking out the rotating shaft.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] A bearing mounting support structure for a white sugar feeding screw conveyor, such as... Figures 1-3 As shown, it includes a feeding cylinder 1, a sugar inlet pipe 2, a sugar outlet pipe 3, a fixed frame 4, a motor 5, a spiral conveyor blade 6, a support frame 7, and a load-bearing component. The sugar inlet pipe 2 is connected to the upper right side of the feeding cylinder 1. The sugar inlet pipe 2 has a bucket-shaped structure. The sugar outlet pipe 3 is connected to the lower left side of the feeding cylinder 1. The fixed frame 4 is connected to the right side of the feeding cylinder 1. The motor 5 is connected to the fixed frame 4. The motor 5 and the processor are electrically connected through a control module. An inner shaft is provided on the output shaft of the motor 5. The spiral conveyor blade 6 is connected to the inner shaft. The support frame 7 is connected to the left side of the feeding cylinder 1. The load-bearing component is provided on the support frame 7.

[0021] like Figures 1-4 As shown, the load-bearing components include a connecting rod 8, a mounting sleeve 9, a first bolt 10, a bearing 11, a rotating shaft 12, and a second bolt 13. The connecting rod 8 is connected to the inner side of the upper part of the support frame 7. The mounting sleeve 9 is divided into upper and lower parts, which are hinged to each other. The upper mounting sleeve 9 is connected to the connecting rod 8. The rear parts of the mounting sleeves 9 are detachably connected by the first bolt 10. The bearing 11 is snapped into the inside of the mounting sleeve 9. The bearing 11 is a double-row self-aligning roller bearing. The horizontal distance between the axis of the bearing 11 and the downstream end of the sugar outlet pipe 3 is 200-300mm, ensuring that the white sugar is completely discharged from the sugar outlet pipe 3 before reaching the bearing 11 and cannot enter the bearing 11 area. The rotating shaft 12 is snapped into the bearing 11. The rotating shaft 12 is detachably connected to the inner shaft by eight second bolts 13. The first bolt 10 and the second bolt 13 are high-strength internal hexagonal bolts (specifications M16-M20).

[0022] When using this device, first install the feeding cylinder 1 on the bracket, then add granulated sugar into the sugar inlet pipe 2. Then, the processor starts the motor 5 on the fixed frame 4 through the control module, which drives the inner shaft to rotate, causing the spiral conveyor blade 6 to rotate. The spiral conveyor blade 6 conveys the granulated sugar, which is then conveyed to the drum dryer through the sugar outlet pipe 3. While the inner shaft rotates, it also drives the bearing 11 and the rotating shaft 12 to rotate. The bearing 11 bears the load and reduces wear. The horizontal distance between the axis of the bearing 11 and the downstream end of the sugar outlet pipe 3 is 200-300mm, ensuring that the granulated sugar is completely discharged from the sugar outlet pipe 3 before reaching the bearing 11 and cannot enter the bearing 11 area. Thus, by changing the installation position of the bearing 11, the bearing 11 can be completely separated from the granulated sugar, avoiding the granulated sugar from getting caught between the bearing 11 and the inner shaft and causing contamination. When it is necessary to disassemble and replace the bearing 11, the first bolt 10 can be loosened by rotating and removed, the mounting sleeve 9 can be opened by rotating and loosening the second bolt 13 and removed, and the rotating shaft 12 can be taken out to replace the bearing 11. This makes it easy to disassemble the bearing 11 and facilitates its replacement or maintenance.
