Heating method of vibrator and vibrator for implementing the method

Abstract

The invention discloses a heating method for a vibrator and a vibrator realizing the method. The method is like following: steam is conveyed through a steam pipeline into the bearing seat of a vibrator, so that the steam will spray toward the outer casing of the bearing seat; the bearing seat and the surrounding environment are heated, the temperature of the lubrication grease in the bearing seat is increased by heat transfer, and the viscosity of the lubrication grease is reduced, so that the vibration sieve can be started rapidly. The vibrator comprises a bearing seat, a bearing, a vibration shaft and eccentric bodies. The bearing is mounted in the bearing seat, the vibration shaft is supported on the bearing; the two ends of the vibration shaft stretches out the bearing seat, and are respectively connected with an eccentric body; on the bearing seat, a steam pipe for delivering steam is fixed on the bearing seat; on the steam pipe, branch pipelines are connected, each branch pipeline is communicated with a circular pipe surrounding the bearing seat; on the circular pipe, two or more steam nozzles are provided toward the bearing seat. The invention can rapidly and evenly heat the bearing seat, is convenient for starting the vibration sieve, is of simple structure, is easy to operate and environment friendly.

Description

technical field [0001] The invention relates to a vibrating screen used in metallurgy, mining, chemical industry, building materials, coal and other industries for material classification, dehydration and deintermediation operations, and in particular to a vibrator heating method and a vibrator for realizing the method. Background technique [0002] Vibrating screens currently used in metallurgy and mining industries are powered by vibrators. The vibrator is installed on the screen box of the vibrating screen and performs high-frequency vibration together with the screen box. The vibrator is composed of bearing housings, bearings, shafts, and eccentric bodies. and other components. After entering the winter in northern my country, as the temperature drops, the lubricating grease in the bearing seat is easy to solidify after the shutdown exceeds 4 to 8 hours, which makes it difficult to start the vibrating screen. Existing solutions generally all are to heat the bearing seat...

AI Technical Summary

Problems solved by technology

However, in winter, especially in northern my country, the ambient temperature is very low, and the heating process takes a long time, and it must be operated manually. The operation here is inconvenient, and it is generally intermittent operation. The vibrating screen cannot be operated during the trial run stage of startup; stop heating After that, the lubricating grease is easy to cool and solidify, which affects the heating effect; the bearing seat of the vibrator is heated by a welding torch or a furnace, and the local temperature is very high, which is easy to cause deformation of the bearing seat
