Problems solved by technology

[0003] The packing gland seal is that the packing is in the packing cavity, and the packing is compressed by the packing gland, so that the packing is in close contact with the packing cavity and the screw shaft, so that the powder can obtain the sealing effect and function in the screw packing device. The packing is generally fiber, Composed of soft tissues such as asbestos and graphite, the wear resistance is not high. The relative movement of the powder between the filler and the screw shaft will inevitably cause the wear of the filler, forming a gap between the filler and the shaft, and causing the powder to leak along the screw axis. Packing seal reliability is not high

Abstract

The invention belongs to the technical field of fluorite processing, and particularly relates to a novel spiral packing sealing device which comprises a driving motor. The speed reduction assembly is mounted at the output end of the driving motor; the starting end bearing seat is mounted at the tail end of the output shaft of the speed reduction assembly; the spiral conveyer main body is mounted at the tail end of the shaft body of the initial end bearing seat; the sealing assemblies are installed on the two sides of the spiral conveyor body, each sealing assembly comprises a sealing installation base, an installation bolt, a sealing end cover, a filler sealing layer and a framework oil seal, and the two sealing installation bases are installed on the two sides of the spiral conveyor body respectively. According to the novel spiral packing sealing device, after novel packing sealing is adopted, the two sealing packing are matched with each other, the sealing effect is better, the service life is longer, existing equipment does not need to be greatly modified, and the novel spiral packing sealing device is convenient to popularize when applied to fluorite spiral conveying equipment.

Description

technical field [0001] The invention relates to the technical field of fluorite processing, in particular to a novel screw packing sealing device. Background technique [0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can be conveyed horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. In terms of conveying form, screw conveyors are divided into two types: shafted screw conveyors and shaftless screw conveyors, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. The shaft screw conveyor is suitable for non-viscous dry powder materials and small granular materials. (For example: cement, fly ash, lime, grain, etc.) and the shaftless screw conveyor is suitable for conveying viscous and easily entangled ...
