Abstract

A bottom sealing device for a bucket elevator, comprising a sealed casing; a driven wheel pressing mechanism, which is sealed and installed on the sealed casing so as to slide up and down; a driven wheel assembly, which is accommodated in the sealed casing, including a driven shaft, a passive Sprocket, seat body, bearing seat, bearing, the bearing seat and the seat body are fixedly connected; the bearing can be accommodated in the bearing seat so that it can rotate left and right, and is limited by the front and rear of the seat body, and the junction of the bearing and the bearing seat forms a line Fitting contact; the end of the driven shaft passes through the seat body to be fixedly connected with the bearing, and a one-way seal assembly is provided between the driven shaft and the seat body, so that the lubricating oil between the bearing and the bearing seat can be irreversibly The direction passes through the one-way seal assembly and is discharged out of the seat body; the lubrication system is used to provide lubricating oil to the driven wheel assembly. The invention effectively solves the problem of powder leakage and dust entering into the bearing seat and damaging the bearing; and can ensure the normal operation of the hoist when there is a large gap.

Description

technical field [0001] The invention relates to the technical field of bucket elevators, in particular to a bottom sealing device of a bucket elevator. Background technique [0002] Bucket elevator is a kind of conveying machinery with a wide range of applications. It can be used to lift sand and gravel, cement, mineral powder, etc. However, when conveying some fine materials with good fluidity, there are problems such as powder leakage and premature damage of the bottom bearing. Such as cement, mineral powder, high-temperature dust, etc. These materials have a particle size of less than 50 μm and have very good fluidity. The materials often leak out from the joint surface between the bottom shell of the hoist and the shaft end slide plate, or enter the inside of the bearing housing to damage the bearing. Contents of the invention [0003] The invention provides a bottom sealing device of a bucket elevator, the main purpose of which is to overcome the defects of powder l...
