Abstract
A protection plate used at an inlet inside a coal steam producing furnace comprises a high-strength impact-resistant plate block, wherein the plate block is provided with a straight edge flush with the lower edge of the fire coal inlet, a bulging reinforcing block is manufactured inwards and integrally with thestraight edge serving as a starting edge, and at least two fixing bolt holes are formed in the plate block on the outer side of the reinforcing block; the plate block is a square block or a semicircular block or a semi-elliptic block which is surrounded by downwards extending two ends, which serve as starting points, of the straight edge, the reinforcing block is in a shape which is identical with or different from that of the plate block and formed on the basis of the plate block, and the three evenly-distributed fixing bolt holes are at least formed in the peripheral plate block except the straight edge. The protection plate has the characteristics of simple structure, convenience in mounting and use, capability of well protecting the furnace wall at the fire coal inlet and further prolonging the service life of the whole coal steam producing furnace and the like.
Description
Technical field
The utility model relates to a kind of baffle for import department in coal vapour producer, belong to the special part of coal vapour producer.
Background technology
Coal vapour producer is by burning of coal, water is added to thermosetting steam, in burner hearth due to coal vapour generator, need to add fire coal, and a large amount of fire coals adds burner hearth from import department, first contact is the hearth wall of import department, and therefore, under normal duty, the hearth wall of import department can be subject to coal-fired shock, shock will cause the breakage of import department's hearth wall for a long time, thereby further affects the service life of whole coal vapour generator.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists; and provide a kind of simple in structure; easy to install, can protect well coal-fired import department hearth wall, and then extend the whole coal vapour producer baffle for import department in coal vapour producer in service life.
The purpose of this utility model completes by following technical solution, it comprises that a bulk strength is high, crash-proof plate, on this plate, there is a straight flange concordant with coal-fired import lower edge, inwardly be made into integration a protruding boss taking this straight flange as playing initial line, and be provided with at least two fixed bolt holes on the plate of the outside of boss.
Described plate is shaped as the square block or half nahlock or the half elliptic piece that enclose as starting point taking the two ends of straight flange downwards, described boss is shaped as the shape identical or different with plate shape forming on described plate basis, and at least on the periphery plate except straight flange, is provided with three uniform fixed bolt holes.
The utlity model has simple in structurely, easy to install, can protect well coal-fired import department hearth wall, and then extend the features such as whole coal vapour producer service life.
