Using method of movable sealing device

Abstract

The invention discloses a using method of a movable sealing device and belongs to the field of mechanical device sealing pieces. The movable sealing device comprises an outer ring body, an inner ring body and a rubber sealing ring and further comprises a limiting rod; the outer ring body and a bearing cover are fixed through a bolt, and the requirement that a gap between a pressing roller and a rotating shaft is large can be met; the rubber sealing ring is arranged in the inner ring body so that the side, close to the rotating shaft, of the inner ring body can be in close contact with the rotating shaft; the two outer sides, opposite to each other in the radial direction, of the inner ring body are of a plane structure; the limiting rod is arranged between the plane structure of the inner ring body and the outer ring body; and when the rotating shaft and an end cover move, the inner ring body and the inner rubber sealing ring can horizontally move relative to the outer ring body so that the sealing function can be achieved. The movable sealing device has the beneficial effects of being simple in structure, reasonable in design, easy to manufacture and good in sealing effect and is especially suitable for sealing between a movable piece and a fixed piece.

Description

[0001] This invention is a divisional application, the original Chinese patent application number: 201510203464.7, the application date: April 24, 2015, the patent name at the time of application: a movable sealing device and its use method. technical field [0002] The invention belongs to the field of mechanical device seals, and more specifically relates to a method for using a movable sealing device. Background technique [0003] High-pressure roller mill is a new type of energy-saving grinding equipment that came out in the mid-1980s. It is one of the intermediate equipment in the process of cement grinding and metal ore crushing. It is the key equipment to achieve more crushing and less grinding. Significantly reduce energy consumption. After the high-pressure roller mill has been greatly popularized and applied in the cement field, in order to make it popular in the metal mine field, the roller surface of the cemented carbide stud is used, which greatly improves the w...

Problems solved by technology

[0006] Aiming at the problems of inflexible sealing and unsuitable for frequent relative movement between fixed parts and moving parts in existing sealing rings, the present invention provides a method for using a movable sealing device, including an outer ring body, an inner ring body, a rubber seal The outer ring body and the bearing cover are fixed by bolts, which can meet the demand for a large gap between the pressure roller and the rotating shaft; the inner ring body is equipped with a rubber sealing ring, so that the side of the inner ring body close to the rotating shaft and the rotating shaft In close contact, the radially opposite sides of the inner ring body are plane structures, and the limit rod is set between the plane structure of the inner ring body and the outer ring body. When the shaft and the end cover are displaced, the inner ring body and the inner rubber The sealing ring can move horizontally relative to the outer ring body to realize the sealing function
