Problems solved by technology

After our long-term observation, the two effects are not ideal, because of the special environment of the site construction, resulting in a large error in alignment, and its service life is greatly reduced. In the past, the service life of bearings aligned by this method is generally 3 to 4 month

Embodiment Construction

[0014] The present invention is a method for replacing the lower bearing of a vertical mill powder separator, including the replacement of the lower bearing and the alignment of the lower bearing. The method includes the following steps:

[0015] Step 1: Remove the tie rod adjustment device; use gas cutting to destructively remove the tie rod adjustment device of the powder classifier;

[0016] Step 2: Remove the lower bearing and base; lift the lower bearing base with a sling chain, remove the flange bolts, and place it on the grinding table;

[0017] Step 3: Install the new bearing and base; put the pre-assembled bearing and base back to the original place with the lifting chain, connect the flange bolts and fasten them in place;

[0018] Step 4: Alignment and connection and adjustment of the pull rods; before the pull rods are connected, the lower bearing of the powder classifier is in a free vertical state, and the bearing position at this time is recorded based on the roo...

Abstract

The invention relates to a replacement method of a lower bearing of a powder concentrator of a vertical mill. The replacement method of the lower bearing of the powder concentrator of the vertical mill includes the replacement of the lower bearing and the centering of the lower bearing. The replacement method of the lower bearing of the powder concentrator of the vertical mill is characterized by comprising the steps of dismantling a pull rod adjusting device, dismantling the lower bearing and a base, installing a new bearing and the base, and centering and connecting and adjusting the pull rod. The replacement method of the lower bearing of the powder concentrator of the vertical mill has the advantages that replacing efficiency of the powder concentrator is improved, the service life of the lower bearing of the powder concentrator is prolonged, cost of replacement parts is saved, and labor intensity is relieved.

Description

technical field [0001] The invention relates to a vertical mill powder separator, in particular to a maintenance method for the vertical mill powder separator. Background technique [0002] The lower bearing of the powder classifier is one of the core equipment of the vertical mill. It mainly consists of the bearing base and the pin shaft fixing the base, lifting lugs, four pull rods and corresponding adjustment devices. [0003] The replacement of the lower bearing, the main disassembly difficulty of the replacement of the lower bearing lies in the disconnection of its four pull rods. Due to the working environment of the powder separator, its internal high temperature, humidity, and dust, the adjustment device connected to the pull rod and the bearing base is prone to rust , it is very difficult to disassemble and assemble, and its replacement location is located at high altitude and in a confined space, so the construction difficulty is also very large. . [0004] For t...
