Abstract
The utility model relates to a coal feeding device for corotation chain grate industrial boilers, comprising a box-type coal feeding scuttle machine frame 10, a horizontal drum 6 is arranged on the machine frame 10 via a rotating shaft. A coal gate 4 is arranged on the coal feeding scuttle machine frame 10 which is arranged above the roller 6, a coal inlet path 1 is arranged on a right upper part of the coal feeding scuttle machine frame 10, and a grid-shaped screen 7 is arranged in a left lower part of the machine frame 10 of the roller 6, and spiral coal shifting gears 5 are fixed on an exterior surface of the roller 6. The utility model has more reasonable structure and is suitable for feeding coal to the boilers with multiple coal types, and meanwhile, the utility model improves utilization performance.
Description
The utility model relates to a kind of coal feeder of positive turning chain furnace row Industrial Boiler.
The coal feeder of traditional positive turning chain furnace row Industrial Boiler is: coal falls into coal bunker through high-order coal bunker, breeching, and under the drive of fire grate, combustion chamber is got in the gap that forms through between coal flashboard and fire grate.The major defect of this coal-feeding mode is: the coal seam is compacted, the powder agglomates interspersion, therefore its ventilation condition is poor, and contacting between coal and air is just not too abundant, thereby causes coal not burn fully, combustible content in the slag is higher, so that influence the combustion efficiency of boiler.Add coal dust and from the slit of fire grate, leak down, also increased coal-fired waste.At above-mentioned drawback, the designer of this utility application has designed a kind of Stratified Charge formula coal feeder, sees Chinese patent ZL94236010.9 number.This device is the cylinder that a band tooth bar has been installed in traditional feeding-coal bucket, the screen of a grate shape has been installed at the downside of cylinder, make coal directly not fall on the fire grate like this through breeching, but it is quantitative through cylinder, after the screening of screen coal is evenly distributed on the fire grate, and make on fire grate uniform by bulk from bottom to top to the loose layering of fritter, thereby improved the ventilation condition in coal seam, coal is burnt fully.This coal supply mechanism for coal cinder relatively uniformly ature of coal be feasible, if when being mingled with gathering coal in the coal, gathering coal blocks cylinder easily, thereby influences coal-supplying amount through the difficulty relatively just of the gap between cylinder and the flashboard.Moreover this coal supply mechanism is relatively poor to the adaptive capacity of coal, has also limited the field of application of this coal supply mechanism.
The purpose of this utility model be to design a kind of rational in infrastructure, to the adaptable layering coal supply of kind, the granularity mechanism of fire coal.
The utility model is to realize like this.This coal supply mechanism comprises a box feeding-coal bucket frame, in this feeding-coal bucket frame, cylinder is installed, advances coal channel, coal flashboard and grate shape sieve, its technical essential is: the coal tooth that axially pulls out on the outer surface of cylinder is changed into helix and dials the coal tooth, when cylinder rotated coal supply, bigger coal cinder can not block cylinder or damage parts like this.
Because this coal supply mechanism changes the axially group coal tooth on the cylinder into helix and dials the coal tooth, not only can avoid bigger coal cinder that cylinder is blocked, but also help bigger coal crusher, by the space between coal flashboard and the cylinder, guarantee the normal operation of coal supply mechanism, make that simultaneously the structure of coal supply mechanism is more reasonable, technology is more perfect.This mechanism is wideer to the applicable area of coal.
Fig. 1 is a structure principle chart of the present utility model;
Fig. 2 is the constructional drawing of cylinder 6 of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
Feeding-coal bucket frame 10 of the present utility model is a box type construction, through rotating shaft horizontal cylinder 6 is installed in the middle, on the feeding-coal bucket frame 10 directly over the cylinder 6, be equipped with one and can adjust coal flashboard 4 up and down, the top-right feeding-coal bucket frame 10 of cylinder 6 is provided with one and advances coal channel 1, bevelled grate shape sieve 7 is installed on the feeding-coal bucket frame 10 of the lower left of cylinder 6, and the outside face of cylinder 6 is fixed with helix and dials coal tooth 5 and form.During use, the coal channel 1 that advances of this coal supply mechanism is connect defeated coal bag, feeding-coal bucket frame 10 is installed on the chain furnace grate 9 before the boiler and gets final product.
In order further to improve the in-use performance of this coal supply mechanism, adapt to different coals, coal flashboard 4 also can be installed on the bearing support 2 of an energy transverse horizontal adjusting, and 2 bindiny mechanisms that regulate through an energy transverse horizontal of bearing support are fixedly mounted on the feeding-coal bucket frame 10.Here the bindiny mechanism between said bearing support 2 and the feeding-coal bucket frame 10 be horizontal guide slot with bolt to the connection structure that cooperates, that is to say on bearing support 2 or coal supply frame 10 to be processed with horizontal guide slot, with bolt the two is coupled together then.If when adjusting the position of bearing support 2,, bearing support 2 transverse horizontal are moved, when it is moved on to preposition, again bolt tightly be got final product as long as unclamp bolt.Bindiny mechanism between bearing support 2 and the feeding-coal bucket frame 10 can also be screw mandrel, screw transmission device or gear, rack gear etc.
Moving up and down of coal flashboard 4 can be adopted traditional bolt, guide barrel construction.Also tooth bar can be processed in the top of coal flashboard 4, this tooth bar is meshed with adjusting gear 3, drives coal flashboard 4 and moves up and down.Coal flashboard 4 also can drive its upper and lower moving by screw mandrel, screw mechanism or sprocket wheel, link chain mechanism etc., adjusts the coal feeding hole width between cylinder 6 and the coal flashboard 4.
In order to solve the problem that feeding-coal bucket frame 10 is burnt in the anti-fire baking of fire door, be installed with a water cooling tank 8 in the junction of feeding-coal bucket frame 10 and fire door, this water cooling tank 8 is connected with cold water source through connecting water pipe.
The grate shape of this coal supply mechanism sieve 7 can adopt single layer structure, also can adopt double-decker, so more can guarantee to be transported on the traveling-grate stoker 9 fire coal from bottom to top, descending loose, the uniform arrangement of layering is burnt fully to guarantee it.
