Abstract
The utility model discloses impingement plates in a water granulated slag groove, which comprises impingement plates and a base plate. The impingement plates are characterized by being divided into small partition blocks and being longitudinally arranged on the base plate in a stepped compressing manner. The impingement plates are arranged on the inner wall of the water granulated slag groove, are the small partition blocks, are embedded in a Z-shaped section and are longitudinally arranged on the base plate in a stepped compressing manner, so that the impingement plates can be mutually compressed to form a whole body and also various impingement plates except the two lowest layers can be detached separately and cannot be influenced mutually. The weight and the size of the impingement plates are only 1/5-1/6 of the weight and the size of the impingement plates in the prior art, so that the quick disassembly and replacement of the impingement plates can be realized, the overhaul and maintenance workload of operation workers can be reduced, the waste and loss caused by requiring to replace one large block of impingement plate even if the impingement plates are locally worn in the prior art can be avoided and the operation and maintenance cost can be reduced.
Description
Technical field
The utility model belongs to field of metallurgical equipment, relates to a kind of blast furnace granulated slag system water slag chute internal impact plate.
Background technology
The grain slag groove is not only grain slag and is entered drum filter fender system before, still a kind of device that can make the further shrend granulation of grain slag and the pulp water flow direction is commutated.In shallow water method grain slag pelletizing technology, grain slag groove sidewall because be subjected to for a long time at a high speed, washing away of high temperature sludge water mixture and very easily wearing and tearing cause potential safety hazard, influence grain slag production.In order to protect grain slag groove inwall, the general employing is provided with wear-resisting impingement plate at grain slag groove sidewall over against the pulp water impact direction.
Because generally about 6m, grain slag groove access door width is also less than 1m for grain slag groove diameter, its built-in function and space for maintenance are at full stretch, and repair apparatus will be transported in the grain slag groove also very difficult.And the inner wear-resisting impingement plate of existing grain slag groove adopts big piecemeal design, the weight of every impingement plate reaches hundreds of kilograms, because size, the weight of this impingement plate are excessive, therefore, cause its maintenance, safeguard very inconvenience and consuming time long, simultaneously, even the concentrated wear of an impingement plate all needs the monoblock impingement plate is changed, not only change frequently and waste greatly.
The utility model content
The purpose of this utility model is to provide the grain slag groove internal impact plate that a kind of size is little, in light weight and be easy to change.
The purpose of this utility model is achieved in that a kind of grain slag groove internal impact plate, comprises impingement plate and base plate, it is characterized in that: described impingement plate is little piecemeal and vertically is installed on the described base plate in the stepped mode that compresses.
In order to guarantee all to compress mutually between the every impingement plate, form an integral body, and when dismounting, can be that unit dismantles separately with the piece, be independent of each other, above-mentioned impingement plate is " Z font " section nested type and horizontal nested connection.
In order to make the above-mentioned impingement plate can Fast Installation and dismounting, above-mentioned impingement plate be bolted on the above-mentioned base plate by wear-resisting, and described wear-resisting bolt is " doing font " and suitable with the bolt hole of " keyhole type " on the described base plate.
Reliable in order to guarantee Stability Analysis of Structures, above-mentioned impingement plate be in bottom one deck for being horizontally disposed with.
Above-mentioned base plate is fixed on the base, and described base is fixed on the grain slag groove inwall.
The utility model has following beneficial effect, the impingement plate that the utility model is arranged on the grain slag groove inwall is little piecemeal and vertically is installed on the base plate in the stepped mode that compresses, laterally rabbet with " Z font " section nested type, not only all can compress mutually between every impingement plate, form an integral body, and, can guarantee to dismantle separately except that the most following each impingement plate two-layer, be independent of each other; Because the weight and the size of impingement plate only are the 1/5-1/6 of prior art impingement plate, therefore, the fast quick-detach and the replacing of impingement plate have been realized, reduced operator's repair and maintenance workload, even and avoided impingement plate concentrated wear in the prior art also to need a bulk of impingement plate is changed and the waste and the loss that cause, reduced operation expense.
