Abstract
The utility model relates to a fire grate of a boiler, in particular to a push-type chain-block fire grate, which solve the problem that the prior movable fire grate is easily deformed after heated. The push-type chain block fire grate includes a chain link formed by connecting a plurality of block-shaped fire grates through connecting pieces, a pushing device is arranged at one end of an upper chain belt of the upper chain link, and a pushing tongue directly pushing chain blocks is arranged at the front end of the pushing device. Compared with the prior art, the utility model firstly adopts the design of connecting the block-shaped fire grates into the chain, so that the fire grates are pushed against one another to move formed, and the pushing force directly acts on the block-shaped firegrates and can not be added onto connecting pin shafts between the block-shaped fire grates in a large amount, therefore the damage probability of the fire grates is greatly reduced and the service life of the boiler is greatly prolonged.
Description
Technical field
The utility model relates to a kind of fire grate of boiler, is specially the block fire grate of a kind of pusher chain type.
Background technology
The fire grate of boiler is positioned at the burner hearth bottom, and it mainly acts on is to support fire coal.The fire grate of general miniature boiler all is that fixed, large-scale boiler needs Coal-fired capacity big, feeding and slag tap and just become the work that workload is huge.The technical staff is designed to chain type with fire grate again, is placed with gripper shoe on the chain, drives fire grate by sprocket wheel then and rotates.Mutual tractive between the ring of the fire grate of this structure chain in moving process and the ring.The fire grate of gravity-flow ventilation molded coal boiler is in running, often can not obtain good cooling, make fire grate and bearing pin under the condition of high temperature, not only bearing pin intensity reduces significantly, and break down the difficult reparation of these faults being subjected to also to be easy under the situation of pulling force distortion.
Summary of the invention
The utility model provides a kind of pusher chain type block fire grate in order to solve being heated the yielding problem in back of existing mobile model fire grate existence.
The utility model is realized by following technical scheme, the block fire grate of a kind of pusher chain type, comprise the chain link that the some block fire grates that link together by connector form, an end of chain belt is provided with propulsion plant on chain link, and the propulsion plant front end is provided with the propelling tongue of direct promotion chain piece.
Described propulsion plant is the fluid pressure type pulling motion device, comprises oil cylinder, piston rod, and piston rod connects the propelling tongue.Described propulsion plant is the mechanical type propulsion plant, comprises motor, and the gear that motor drives by decelerator, and the tooth bar of gear drive, tooth bar front end connect the propelling tongue.
Compared with prior art, the utility model has at first adopted some block fire grates has been connected catenulate design, can increase considerably supporting power, key be to use propulsion plant from chain row's a side to block fire grate applied thrust, this bulk fire grate before pushes away other block fire grate successively, advance by mutual thrust between the so block fire grate, thrust directly acts on block fire grate and can be added in large quantities on one's body and not on the connection bearing pin between them, the impaired probability of fire grate just reduces greatly like this, and also prolong greatly the service life of boiler.
