Bucket elevator tail wheel transmission bearing air sealing and dust leakage detection device

Abstract

The invention provides a bucket elevator tail wheel transmission bearing air sealing and dust leakage detection device. A transmission bearing air sealing device comprises a transmission shaft, bearings, bearing pedestals, a seal cartridge, an inner sleeve, a sealing plate, fixing flanges and a fixed rack. The two ends of the transmission shaft are fixedly connected with the bearings. The outer portions of the bearings are provided with the bearing pedestals. The tail ends of the bearing pedestals are provided with sealing covers. Each sealing cover is fixedly connected with the correspondingbearing pedestal through bolts. The upper portion of each bearing pedestal is provided with an oil injection nozzle, a temperature sensor and an adjusting lead screw, and the lower portion of each bearing pedestal is provided with an oil discharge cup and a tension lead screw. The bearing pedestals are fixedly connected with the seal cartridge through flanges and bolts. A dust leakage detection device comprises a sealing shell, a dust detection device and an observation cup. The sealing shell is fixedly connected with a bucket elevator shell and is connected with the tail of a drain pipe. Thedust detection device is arranged in the sealing shell. Air sealing is realized. The situation that abrasion deformation of a sealing material is serious within a short time due to the fact that the gap between a spindle of a tail transmission device and a seal cartridge cannot remain stationary is avoided.

Description

technical field [0001] The invention relates to a sealing device of a bucket elevator tail wheel transmission bearing and a transmission bearing seal leakage detection device used in industry. Background technique [0002] Bucket elevators are also widely used in the industrial field. In actual operation, the gap between the main shaft and the sealing sleeve of the tail transmission device cannot be kept in a fixed state, and the sealing material is severely worn and deformed in a short period of time. Dust enters the sealing sleeve and rubs with the sealing material, causing the shaft Damage, bearing damage, bearing and spindle locking are also very common, especially people cannot effectively detect and identify the damage of sealing materials and the problem of seal leakage. Personnel should regularly check the operation status and sealing condition of the bearings. It is impossible to know the wear condition of the sealing materials. The maintenance personnel can only re...
