The spiral conveyor is mainly used for horizontal or tilting conveying small blocks, granular and powdered materials.
However, when the spiral conveyor is transported, the particles of the material are small, so once the sealing is not good, it is easily caused by the phenomenon of sprinkle. Therefore, the sealing measures when the spiral conveyor delivery of powdery materials becomes an important part of our needs. Well-sealing measures when the spiral conveyor is delivered to the powder
1. In the inside of the housing of the helical conveyor, the disk sealing structure is increased. The root sealing structure is mainly composed of a compression cover, sealing seat, a coupling wall, a plate, a compression bolt, and the like.
The improved structure makes the bearing to the protection of the double seal, while the increased disk is sealed can also make daily maintenance easy. Moreover, when the disc is abnormal, the powder is also discharged from the square hole on the wall, and does not enter the bearing housing.
2. The oil seal in the spiral conveyor is further sealed. When replacing the disk, there is no need to remove the bearing housing, as long as the embossed cover is loose, the plate roots will be put into the seal, and then the compression cover is pressed, and the operation is simple and convenient and the time is less, saving time and effort. This improved sealing structure eliminates the possibility of flowing into the bearing of the powder, and increases the life of the bearing in a large extent, reducing the maintenance work and cost due to replacement bearing, indirectly reduces investment costs.
3. Improvement of the structural spiral conveyor structure, summarize the problems in the previous design experience and the actual work process, and take care of the operability It is proposed. After actual operating test, the improved program effect is still relatively good, and it is simple and easy.
It is basically a problem that the previous sealing effect is not good, the bearing is more difficult, and can be implemented on the general screw conveyor.
