Abstract
The utility model discloses a middle suspension device for a novel screw conveyer, which is connected with an upper section shaft and a lower section shaft of the novel screw conveyer through connecting flanges and is fixed with a top cover plate of the screw conveyer through bolts. The bearing seat is split, and a split bearing is arranged in the bearing seat, so that disassembly, assembly and maintenance are convenient. The top cover plate is provided with the lubricating grease filling port, daily maintenance is facilitated, bearing abrasion is reduced, and the service life of the bearing is prolonged. Bearing block built-in sealing boxes are arranged on the two sides of the bearing, packing and sealing packing mud are arranged in the sealing boxes, a dynamic sealing layer is formed, and materials are effectively prevented from entering. And the top cover plate is provided with a filler mud filling pipe, so that lost sealing filler mud can be supplemented. The sealing filler mud is in a daub shape, contains graphite and low-friction-coefficient fibers, adapts to the temperature range of-20 DEG C to 200 DEG C, can reduce friction and abrasion, maintains the sealing performance, can absorb impact loads, prolongs the service life of a sealing system and the service life of a spiral conveyor, and improves the overall operation efficiency of equipment.
