Abstract
The invention discloses an endless grate, in particular to a big wind bin and small wind catcher crossbeam-type endless grate. The endless grate comprises a frame consisting of a middle beam (2), an upper lead rail (1) and a lower lead rail (12); a furnace chain connected with a drive device is arranged on the frame; the endless grate is characterized in that: the lower part of the furnace chain on the upper part is provided with a wind bin (11) communicated with the furnace chain; a wind chest (14) communicated with the wind bins (14) is arranged on the whole side of the grate; the wind chest (14) is connected with a wind supply device. The endless grate changes the mode that each wind chamber respectively supplies wind in the prior art, thereby greatly reducing wind speed, stabilizing wind pressure, ensuring the even wind supply to the furnace chain, improving the burning quality of fuel and saving energy.
Description
Technical field
The present invention 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 invention is to provide 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 invention, 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 invention, 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 invention, 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 invention, 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 present invention;
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 12 is lower guide, constitute framework by central sill 2, upper rail 1, lower guide 12, 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.
