Abstract
The utility model discloses a chain grate, in particular to a trabeate style chain grate with big wind barn and small wind bucket, which comprises a frame formed by a middle beam (2), an upper guide rail (1) and a lower guide rail (12). The frame is provided with a furnace chain connected with a drive device. The utility model is characterized in that: a mutually-communicated wind barn (11) is arranged at the lower part of the furnace chain arranged at the upper part; a blast box (14) communicated with the wind barn (11) is arranged at the total lateral face of the chain grate and is connected with a wind-supply device (14). The utility model has the advantages of changing the mode separately supplying wind of each air compartment of the prior art, greatly lowering wind speed, stabilizing wind pressure, guaranteeing even wind supply to the furnace chain, improving burning quality of fuel and saving energy source.
Description
Technical field
The utility model relates to a kind of traveling-grate stoker, particularly a kind of large wind barn small air scoop crossbeam type chain-grate.
Background technology
At present, the combustion apparatus that large-sized boiler adopted mainly is a crossbeam type chain-grate, the structure of crossbeam type chain-grate is to have one by central sill, the framework that upper rail and lower guide constitute, in the framework upper support stove chain is arranged, stove chain and drive unit join, form each independently air compartment below the superposed stove chain and between the adjacent central sill, by each independent air compartment and the air supply device air zoning that is connected with air compartment, this structure is owing to the wind speed that enters fire grate is higher, dynamic pressure proportion is excessive, and exist phenomenons such as the diffusion of serious wind and eddy current, caused the cloth wind of grate surface inhomogeneous, the wide more this phenomenon of fire grate is obvious more, thus the influence burning, reduce efficiency of combustion, wasted coal resources.
Existing crossbeam type chain-grate adopts on the common board-like wallboard and has the air inlet that joins with air supply device, air-admitting surface is all less than the sectional area of each air compartment, it is high and be accompanied by the variation of the static pressure distribution that the diffusion of air-flow causes to enter the wind speed of air compartment in the air feed process, also can cause cloth wind inhomogeneous.
Summary of the invention
The purpose of this utility model provides that a kind of air feed wind speed is low, blast is stable, cloth wind evenly, improve fuel combustion quality, energy-conservation large wind barn small air scoop crossbeam type chain-grate, overcome the deficiencies in the prior art.
Large wind barn small air scoop crossbeam type chain-grate of the present utility model, it comprises the framework that is made of central sill, upper rail and lower guide, the stove chain that joins with drive unit is installed on the framework, it is characterized in that: superposed stove chain below is provided with the wind storehouse that is interconnected, on the full side of fire grate the bellows that are connected with the wind storehouse are arranged, bellows connect air supply device.
Large wind barn small air scoop crossbeam type chain-grate of the present utility model, wherein said upper rail is provided with brace summer, is fixed with wind scoop on brace summer, between superposed stove chain of wind scoop and the wind storehouse, is provided with the air regulating board that is used to transfer wind at the Di Kouchu of wind scoop.
Large wind barn small air scoop crossbeam type chain-grate of the present utility model, the mouth place is provided with at least two air regulating boards that are used to transfer wind at the bottom of wherein said each wind scoop, each air regulating board is connected by bearing pin with connecting rod, connecting rod is connected by bearing pin with rocking bar, rocking bar is fixedlyed connected with axle and is supported on the support by axle, support is fixed on the central sill, and shaft end connects removes handle.
Large wind barn small air scoop crossbeam type chain-grate of the present utility model, because superposed stove chain below is provided with the wind storehouse that is interconnected, on the full side of fire grate, the bellows that are connected with the wind storehouse are arranged, bellows connect air supply device, have therefore changed to be divided into each air compartment mode of air feed respectively in the prior art, and wind speed is reduced greatly, blast is stable, assurance is even to stove chain place air feed, has improved the burning quality of fuel, has saved the energy.
Because upper rail is provided with brace summer, on brace summer, be fixed with wind scoop, between superposed stove chain of wind scoop and the wind storehouse, be provided with the air regulating board that is used to transfer wind at the Di Kouchu of wind scoop, can carry out air quantity by air regulating board as required and regulate, further guarantee burning quality.
Because the mouth place is provided with at least two air regulating boards that are used to transfer wind at the bottom of each wind scoop, each air regulating board is connected with pitman shaft, and connecting rod is connected with rocker shaft, and rocking bar is connected with support shaft, and support is fixed on the central sill, and rocking bar connects removes handle, makes to transfer wind convenient operation easily; Because a plurality of air regulating boards are arranged, can reduce its size, when being rotated, air regulating board miscellaneous part is not exerted an influence.
Description of drawings
Fig. 1 is the structural representation of the concrete real mode of the utility model;
Fig. 2 is that schematic diagram is looked on a left side shown in Figure 1;
Fig. 3 is an I portion enlarged diagram shown in Figure 1.
The specific embodiment
As shown in the figure: 2 is central sill, and 1 is upper rail, and 3 lower guide constitute framework by central sill 2, upper rail 1, lower guide 3, and the stove chain that joins with drive unit is installed on framework, and the stove chain circularizes shape and rotates the superposed stove chain of fuel top during work.Below the stove chain on top, form the wind storehouse 11 that is interconnected, be to be processed with through hole 15 on each central sill 2, zone between the adjacent central sill 2 interconnects by through hole 15, below the stove chain, form the strong wind storehouse 11 of an integral body, with form between each central sill 2 in the prior art one independently air compartment compare and differ widely.On whole sides of the both sides of whole fire grate the bellows 14 that are connected with wind storehouse 11 are arranged, bellows 14 connect air supply device.Air supply device is blown in the bellows 14 of both sides during work, and the air intake in the storehouse 11 aweather through whole sides of fire grate both sides has strengthened air supply areas again, greatly reduce wind speed, the wind that is conducted to stove chain place is evenly distributed, thereby has reduced on-way resistance and local resistance, can reduce the power consumption of air blast.
Upper rail 1 is provided with brace summer 3, is fixed with wind scoop 4 on brace summer 3, between wind scoop 4 superposed stove chains and the wind storehouse 11, is provided with the air regulating board 8 that is used to transfer wind at the Di Kouchu of wind scoop 4.The Di Kouchu of each wind scoop 4 is equipped with three air regulating boards 8 that are used to transfer wind in this specific embodiment, a wind scoop interval 6 is being arranged between each air regulating board 8 on the wind scoop 4, the bottom of each air regulating board 8 is connected with 19 on connecting rod, connecting rod 19 is connected by bearing pin 18 with rocking bar 7, rocking bar 7 is fixedlyed connected with axle 21, and be supported on the support 22 by axle 21, support 22 bolting are connected on the central sill 2, and the termination of axle 21 connects removes 5.Can move when transferring wind and axle 21 and rocking bar 7 are turned an angle with respect to support 22, rocking bar 7 drivening rods 19 translations simultaneously, the translation of connecting rod 19 can drive three air regulating boards 8 and rotate, and reach the size of change wind scoop 4 end mouth and the purpose of regulating air quantity.
