Abstract
The utility model discloses a stoke rod of a chain-grate boiler stoke machine with small surface area, which is characterized in that the utility model includes a water outlet pipe (6) that is provided with stoke teeth (11) communicated with the water outlet pipe; the water outlet pipe (6) is also internally provided with a water inlet pipe (5) communicated with the water outlet pipe; the stoke rod has simple structure, and the weight of a cantilever is reduced 40 percent compared with the original cantilever, the surface area of the cantilever is greatly reduced, so as to reduce the heating surface area of the stoke rod in the furnace and enhance the bearing strength of the stoke rod.
Description
Technical field:
The utility model relates to a kind of chain-grate boiler machine that pokes fire, the poke fire bar that pokes fire of machine of specifically a kind of chain-grate boiler.
Background technology:
The all types of chain-grate boiler One's name is legions of China's active service, but, be the thermal hardware that is most widely used in present industrial enterprise, small hydropower station and the domestic heating engineering owing to be designed to advantages such as the adjusting load of maximum and automated production management and maintenance cost are low.For moving, arrange red slag phenomenon after the burning that has solved chain-grate boiler, generally be provided with the machine of poking fire, stirring the coal seam of burning, and be issued to loose slag in the effect of air blast at the observation door place of body of heater, the purpose of the shape that partly seethes with excitement burning, the boiling that produces truly becomes layer activation burning.And the existing bar that pokes fire generally is made up of two water-in and water-out tube side-by-sides, and at one end with on the tooth that pokes fire links to each other and constitute cooling circuit, its complex structure, and cantilevered weights is big, and processing is inconvenient, and the cantilever surface area is big, the poke fire intensity of bar of influence.
Summary of the invention:
The purpose of this utility model provides the poke fire bar that pokes fire of machine of the little chain-grate boiler of a kind of surface area.
The utility model is to adopt following technical scheme to realize its goal of the invention, the poke fire bar that pokes fire of machine of a kind of chain-grate boiler, and it comprises outlet pipe, outlet pipe is provided with the tooth that pokes fire that communicates with it, is provided with the water inlet pipe that communicates with it in outlet pipe.
Water inlet pipe described in the utility model is installed in the outlet pipe by bracing frame.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, cantilevered weights has reduced by 40% than originally, the cantilever surface area also reduces greatly, has reduced the heating surface area of bar in stove that poke fire, and has increased the bearing strength of the bar that pokes fire.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as can be known, the poke fire bar that pokes fire of machine of a kind of chain-grate boiler, it comprises outlet pipe 6, and outlet pipe 6 is provided with the tooth 11 that pokes fire that communicates with it, is provided with the water inlet pipe 5 that communicates with it in outlet pipe 6, and described water inlet pipe 5 is installed in the outlet pipe 6 by bracing frame 14.
The utility model is below two hand hay cutter primary zone observation doors of chain-grate boiler, the carrying girder steel place, top of air compartment airduct 13 is welded with the track of being made up of two parallel steel rails 4, power set include motor and by the deceleration eccentric wheel 3 of its drive, promote railcar 1 by the connecting rod on the deceleration eccentric wheel 37, drive the bar 2 that pokes fire and on grate surface 12, do the action that pokes fire repeatedly.The bar 2 that pokes fire is parallel to grate surface 12, and cantilever is installed on the railcar 1, and the bar 2 that pokes fire is concentric tubes of being made up of water inlet pipe 5 and outlet pipe 6, and water inlet pipe 5 is installed in the outlet pipe 6 by bracing frame 14, and constitutes the cooling duct.The tooth 11 that pokes fire is distributed on the bar 2 that pokes fire, can be according to the fire grate width increase and decrease quantity of different model.Temporary track 10 be used to the to poke fire stove of bar 2 is installed outward, is located and keeps in repair.When poking fire bar 2 operations, closed furnace door 9 prevents that air from sealing in burner hearth.Security protection when safty shield 8 is used to move.
The utility model makes running orbit more accurate with the form operation of railcar, and coefficient of friction more reduces.Adopted temporary track 10 simultaneously,, reduced taking up room of equipment for installing and maintenance provides conveniently switch mode.
