A sealing device for the grinding roller door of a vertical mill

Abstract

This utility model discloses a sealing device for the grinding roller door of a vertical mill, including a vertical mill grinding roller door flange welded to the grinding roller door. The outer surface of the vertical mill grinding roller door flange is covered with wear-resistant canvas. A vertical mill grinding roller door seal is provided above the wear-resistant canvas. Both ends of the vertical mill grinding roller door seal and the wear-resistant canvas are tightly bound to the vertical mill grinding roller door flange by clamps. By installing a sealing flange at the mill door, the vertical mill grinding roller door seal and the wear-resistant canvas are tightly bound to the sealing flange by clamps at both ends, so that a sealing cavity wrapped around the grinding roller body is formed inside the mill door seal, achieving a gapless seal and ensuring no material leakage and no air leakage.

Description

Technical Field

[0001] This utility model relates to a sealing device, and more particularly to a sealing device for the grinding roller door of a vertical mill. Background Technology

[0002] The sealing area of ​​the vertical mill roller door in the cement industry is narrow and difficult to construct. Due to the high wind pressure, high wind speed and frequent expansion and contraction movements at this location, the original seal is easily damaged. The exposed gap can easily lead to the leakage of materials or gas from inside the mill into the outside environment, polluting the environment, increasing the maintenance cost of the vertical mill, and also increasing safety hazards. Utility Model Content

[0003] This invention provides a sealing device for the grinding roller door of a vertical mill to overcome the defect in the prior art where the sealing element at the grinding roller door is easily damaged, leading to leakage.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a sealing device for the grinding roller door of a vertical mill, including a vertical mill grinding roller door flange welded to the grinding roller door of the vertical mill. The outer surface of the vertical mill grinding roller door flange is covered with wear-resistant canvas. A vertical mill grinding roller door seal is provided above the wear-resistant canvas. Both ends of the vertical mill grinding roller door seal and the wear-resistant canvas are tightly held to the vertical mill grinding roller door flange by clamps.

[0005] Furthermore, the material of the vertical mill grinding roller door seal is a rubber-based composite material.

[0006] Furthermore, the wear-resistant canvas is made of any one of Oxford cloth, woolen cloth, or rigid nylon.

[0007] Furthermore, the material of the vertical mill grinding roller flange is ordinary carbon structural steel.

[0008] Furthermore, the clamp and the vertical mill grinding roller gate flange also serve to restrict the forward and backward movement of the vertical mill grinding roller gate cylinder.

[0009] The beneficial effects achieved by this utility model are as follows: by installing a sealing flange at the mill gate, the mill roller door seal and the wear-resistant canvas are tightly held to the sealing flange by clamps at both ends, so that a sealing cavity wrapped around the mill roller body is formed inside the mill gate seal, achieving a gapless seal and ensuring no material leakage and no air leakage. Attached Figure Description

[0010] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings: Figure 1This is a schematic diagram of the structure of this utility model.

[0012] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] Example 1 like Figure 1 As shown, a sealing device for the grinding roller door of a vertical mill includes a vertical mill grinding roller door flange 4 welded to the grinding roller door of the vertical mill. The outer surface of the vertical mill grinding roller door flange 4 is covered with a wear-resistant canvas 3. A vertical mill grinding roller door seal 1 is provided above the wear-resistant canvas 3. Both ends of the vertical mill grinding roller door seal 1 and the wear-resistant canvas 3 are tightly held to the vertical mill grinding roller door flange 4 by clamps 2.

[0014] The material of the vertical mill grinding roller door seal 1 is a rubber-based composite material.

[0015] The wear-resistant canvas 3 is made of any one of Oxford cloth, woolen cloth, or hard nylon.

[0016] The material of the vertical mill grinding roller flange 4 is ordinary carbon structural steel.

[0017] The vertical mill grinding roller gate flange 4 and clamp 2 also have the function of restricting the back-to-back movement of the vertical mill grinding roller gate cylinder.

[0018] By forming a sealed cavity at the vertical mill roller door through the vertical mill roller door flange 4 and the vertical mill roller door seal 1, the flow of gas inside and outside the vertical mill can be prevented, the gas entering the mill door seal cover can not be leaked out, and the cold air from the outside can be isolated from entering the mill. The vertical mill roller door seal 1 of this application can adapt to the space requirements of thermal expansion and contraction and front and back movement of the vertical mill cylinder.
