Technical Field
The utility model relates to a grinding equipment accessory technical field specifically is a novel immediately, grind roller door seal structure.
Background
The vertical mill is used as a large-scale grinding device and is widely applied to industries such as cement, electric power, metallurgy, chemical industry, non-metal ore and the like. It integrates crushing, drying, grinding and grading conveying into a whole, has high production efficiency, and can grind blocky, granular and powdery raw materials into required powdery materials. The air leakage of the grinding roller door of the vertical mill is always a big problem which troubles enterprises using the vertical mill, and the influence is mainly reflected in the problems of reduction of the normal working efficiency of the vertical mill, reduction of yield, increase of grinding power consumption and the like.
The seal structure of present commonly used adoption is for installing the rubber slab and externally installing the canvas parcel around rocking arm and casing seal carrier, and it is loaded down with trivial details and change the trouble to install, and this kind of structure is simultaneously because the material problem, and rubber slab and canvas elasticity compensation ability are not enough when the up-and-down motion is done to the rocking arm for this seal structure life is shorter, and because wearing and tearing and wind erosion effect during the use, gap between rubber slab and the seal carrier grow gradually, the canvas breach, the amount of wind that leaks increases then.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel immediately, grind grinding roller door seal structure to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a novel vertical mill grinding roller door sealing structure comprises an arc plate fixedly arranged on a vertical mill shell, a silicon rubber sealing ring which is sleeved with the outer edge of a vertical mill rocker arm and fixedly arranged on the arc plate, and a protective plate which is positioned between the vertical mill grinding roller and the silicon rubber sealing ring and fixedly arranged on the vertical mill shell;
the silicon rubber sealing ring is in a semi-tire shape, a flange ring is integrally formed at the outer edge of the silicon rubber sealing ring and fixedly connected with the arc plate through bolts, and an embracing ring is integrally formed at the inner edge of the silicon rubber sealing ring and fixedly arranged on the vertical grinding rocker arm through a clamping ring.
Optionally, the backplate by with found mill shell's inner wall looks welded first wear-resisting steel sheet, second wear-resisting steel sheet and the concatenation of third wear-resisting steel sheet form, first wear-resisting steel sheet second wear-resisting steel sheet with enclose between the third wear-resisting steel sheet and closed the oblong hole.
Optionally, the clasp comprises an American-type hose clamp.
Compared with the prior art, the utility model provides a novel immediately, grind grinding roller door seal structure possesses following beneficial effect: the utility model discloses the installation is simple, and easy the change fills the clearance between vertical mill rocking arm and the vertical mill casing through the silicon rubber sealing ring that is half tire shape, and the silicon rubber sealing ring has outstanding compensation ability in arbitrary vertical mill rocking arm home range, thoroughly stops the emergence of the problem of leaking out, prevents through the backplate that the compounding wind in the vertical mill from scouring away the silicon rubber sealing ring, prolongs the life of silicon rubber sealing ring.
