Abstract
The utility model discloses an intermediate-speed grinding ceramic stationary ring comprising a stationary ring main body part, wherein the main body part is of a conical ring and is divided into a plurality of small parts for assembling, the small parts divided from the main body part are arc-shaped steel plates, the peripheries of which are provided with steel plate frames; the inner walls of the arc-shaped steel plates are fixed with dovetail strips; and a layer of wear-resisting ceramic plates are attached on the inner walls of the arc-shaped steel plates by the dovetail strips. The intermediate-speed grinding ceramic stationary ring has the advantages of having simple structure, low cost, high and good wear resistance performance and long service life, being conveniently installed, reducing replacement times of the stationary ring, and ensuring the continuity and stability of production.
Description
Technical field
This reality
The novel medium-speed pulverizer parts that relate to are specially a kind of good ceramic stationary ring of anti-wear performance on the medium-speed pulverizer that is used for.
Background technology
The medium-speed pulverizer stationary ring is fixed on the casing, be subjected to the effect of rotating ring and grinding roller, it is one of the most serious position of whole thermal power plant pulverized coal preparation system wearing and tearing, it is whole circular that former power plant grinding machine stationary ring abrasionproof adopts manganese steel to be made into, and cost is high and be not durable, and stationary ring often is worn through, causing stops production changes stationary ring, not only labour intensity is big, and production cost is strengthened, and the economic interests loss is serious.
The utility model content
The technical problem that the utility model solved is to provide a kind of medium-speed pulverizer pottery stationary ring, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
Medium-speed pulverizer pottery stationary ring comprises the stationary ring main part, and described main part is the circular cone ring, according to installation requirements, main part is divided into plurality of small blocks carries out assembly unit.
Notable feature of the present utility model is: it is curved plate that main part is cut apart the fritter that obtains, and periphery is provided with the steel plate frame, and the curved plate inwall is fixed some coattail strips, utilizes coattail strip to attach one deck wear-resistant ceramic sheet at the curved plate inwall.
In the utility model, described wear-resistant ceramic sheet also adopts the arc design.
Beneficial effect:
The utility model is simple in structure, and cost is low, and high-wear resistance is good, and is easy for installation, and physical life is long, has reduced stationary ring and has changed number of times, has guaranteed the continuity and the stability of producing.
Description of drawings
Fig. 1 is the structural representation of main part fritter in the specific embodiment
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The medium-speed pulverizer of this specific embodiment indication pottery stationary ring comprises the stationary ring main part, is 3.6m on the diameter, following 3.4m, and high 0.15m circular cone ring is considered easy for installationly, splices installation so be divided into 24 fritters.
Referring to Fig. 1 is the structural representation of main part fritter in the specific embodiment, it is curved plate 1 that main part is cut apart the fritter that obtains, periphery is provided with steel plate frame 2, curved plate 1 inwall is fixed some coattail strips 3, utilize coattail strip 3 to attach one deck wear-resistant ceramic sheet 4 at curved plate 1 inwall, wear-resistant ceramic sheet 4 in the specific embodiment also adopts the arc design, to keep attaching tight with curved plate 1.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
