Abstract
The invention relates to a turnover type transverse sectional air-regulating fire grate of separate wind rooms. The turnover type transverse sectional air-regulating fire grate comprises furnace chains which are arranged on a stand and are connected with a power device, central beams which constitute the stand and are arranged transversely at intervals, an upper slideway, each separate wind room which is arranged below an upper fire grate and a dust discharging device arranged on the lower part of each separate wind room, wherein each separate wind room is formed by adjacent central beams and wallboards which are separately connected with the two ends of each central beam, the wallboards on the two sides are provided with air inlets which are communicated with an air duct; the dust discharging device is arranged on the lower part of each separate wind room; a plurality of air-regulating plates are arranged on the upper part of each separate wind room along the transverse direction of the fire grate, and each air-regulating plate is connected with a driving rotation shaft. The sectional air-regulating control can be performed in the transverse direction of the fire grate with the above structure according to the combustion situation of fuel above the fire grate, thus overcoming the defect that the air-regulation is performed on the two ends of each separate wind room and the transverse sectional control air-regulation of the fire grate can not be realized, ensuring the sufficient burning of fuel, increasing the thermal efficiency of fuel and saving energy.
Description
Technical field
The present invention relates to a kind of fire grate, particularly a kind of independent air compartment turnover type transverse sectional adjustment chain grate of wind.
Background technology
Fire grate is the combustion apparatus of boiler, and the stove chain in the fire grate can rotate under the driving of driving mechanism, and fuel places the top of fire grate, moves forward with the rotation of stove chain, and fuel burns in moving process, moves to discharge after the other end forms slag.When burning by air supply device air feed on the grate surface, the wind of confession blow over from the bottom to top grate surface, reach the purpose to the fuel air feed.At present, boiler grate mostly adopts the air feed structure that independent air compartment is set below grate surface, be that whole fire grate longitudinally is furnished with several independent air compartments, each air compartment is furnished with louver in the fire grate both sides, wind blows into air compartment by the fire grate both sides, blown on the grate surface by air compartment, the louver of adjusting fire grate both sides can be controlled the air quantity on the grate surface again.Since wind when blowing into air compartment by the fire grate both sides wind speed higher and exist the phenomenon such as diffusion to cause grate surface cloth wind inequality, the wider grate surface cloth of fire grate wind is more inhomogeneous.If fuel bed is uneven along the cross direction profiles granularity on the grate surface, do wet uneven, can be more serious when thickness of feed layer is uneven, cause burning not to the utmost, reduce boiler combustion efficiency, waste energy.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to control, fire grate transversal sectional and transfer wind, guarantee the transversely even sufficient independent air chamber flap type transverse segmented air adjusting grate of fuel combustion of fire grate, overcome the deficiencies in the prior art.
Independent air chamber flap type transverse segmented air adjusting grate of the present invention, comprise the stove chain that joins with power set that is installed on the support body, form central sill support body and that be horizontally arranged at interval, upper rail, be positioned at stove chain below, top each independent air compartment, be positioned at the cinerary device of independent air compartment below, it is characterized in that: described independent air compartment is to surround by adjacent central sill with wallboard that the central sill two ends is joined, and the wallboard of both sides is provided with the air inlet that is connected with wind channel; Each independent air compartment below is equipped with described cinerary device; Along several turnover plate type air regulating boards that is horizontally arranged with of fire grate, each air regulating board connects respectively drive shaft above each independent air compartment.
Independent air chamber flap type transverse segmented air adjusting grate of the present invention, the inboard, top of wherein said adjacent central sill is provided with downward baffle plate, and described air regulating board is positioned at the following formed uptake of baffle plate place.
Independent air chamber flap type transverse segmented air adjusting grate of the present invention, wherein said drive shaft of joining with air regulating board are installed on the supporting sealing plate, and the upper rail of supporting sealing plate and its top joins.
Independent air chamber flap type transverse segmented air adjusting grate of the present invention, in running, all form an independently air compartment between every adjacent central sill, blow to independent air compartment by the air inlet on two end wall panels of this air compartment, then to blowing up to grate surface, because several air regulating boards are shown along the fire grate transverse row in each independent air compartment top, each air regulating board can rotate by connected drive shaft, air regulating board is rotated to an angle, reach the purpose of opening air outlet, therefore, the combustion case of fuel carries out segmentation and transfers wind control above fire grate transversely can be according to fire grate, has overcome in the prior art to transfer wind at the two ends of independent air compartment and can't carry out the defective that wind is transferred in segmentation control, has guaranteed the abundant burning of fuel, improve the thermal efficiency of fuel, saved the energy.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is A-A sectional schematic diagram shown in Figure 1;
Fig. 3 is B section enlarged diagram shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2, 3: 1 for being installed in the stove chain on the support body, and during operation, the stove chain rotates under the drive of driving mechanism, and fuel places on the superposed grate surface 13 and with the stove chain and moves forward.Comprise in the frame structure along several central sills 2 fire grate longitudinal arrangement and that horizontally set is parallel to each other and the upper rail 10 that is supported on the central sill 2, the two ends that are positioned at central sill 2 between adjacent central sill 2 are welded with side wallboard 6, and adjacent central sill 2 and wallboard 6 have surrounded several and be positioned at several independent air compartments 11 of fire grate below, top.The wallboard 6 of both sides is provided with the air inlet 5 that is connected with wind channel 12.Between adjacent central sill 2, be connected to the baffle plate 3 of downward setting with central sill 2, bottom place at baffle plate 3 forms uptake, above independent air compartment 11, be positioned at the uptake place along several turnover air regulating boards 4 of fire grate horizontally set, be connected with drive shaft 7 below each air regulating board 4, drive shaft 7 is led to the side of fire grate support body and is supported on the support body, fixed handle or handwheel are switched through in the termination of drive shaft 7, can drive coupled air regulating board 4 in the fire grate both sides by turning handle or handwheel turns an angle, in running, the opening angle of the combustion case transversal sectional control air regulating board of visual fire grate top fuel guarantees that wind supply quantity that each independent air compartment 11 makes progress is distinguished to some extent or identical.Can mutually stagger certain distance and be arrangeding in parallel of each above-mentioned drive shaft 7, also can adopt tubular axis form mutual sheathing to form concentric together and be supported on the side of fire grate support body, its termination connects respectively driving handle or handwheel drives respectively coupled air regulating board.Drive shaft 7 is installed in and supports on the sealing plate 9, and each supports sealing plate 9 and is welded on the upper rail 10.Be provided with cinerary device 8 below each independent air compartment 11, this part is that the prior art part no longer describes in detail.
