Abstract
A folding chain belt fire grate segment comprises a fire grate segment body (3), whose front and back end are linked with a connecting eat (1), the pinholes (2) are equipped on the connecting ear (1), The folding chain belt fire grate segment is characterized in that the connecting ears are set in a stagger and parallel way.
Description
Technical field:
The utility model relates to a kind of light-duty travelling grate stoker sheet that is applied on the traveling-grate stoker formula boiler.
Background technology:
Traveling-grate stoker formula boiler is fuel to be placed on the fire grate of rotation burn, fire grate be by chain and on parts such as fire grate segment constitute.At present, the low capacity boiler generally adopts light-duty continuous band fire grate, and wherein the two sides of fire grate segment are straight, and is connected in series by fire grate long pin, forms the stove chain.Because be the parallel surface contact between fire grate segment, causing cloth wind wind line is the multiple row parallel lines, wind distributing face is narrower, and cloth wind poor effect easily produce the insufficient phenomenon of burning, and it is serious to leak coal, wastes energy.And existing fire grate segment volume, weight are bigger, and cost is higher.
Summary of the invention:
The utility model is at the deficiencies in the prior art, provide a kind of light, leak the broken-line type travelling grate stoker sheet that coal is light, have good cloth wind effect.
Technical solution of the present utility model is: a kind of broken-line type travelling grate stoker sheet, be provided with fire grate segment body 3, and its front and rear portions is connected to engaging lug 1, and pin-and-hole 2 is arranged on the engaging lug 1, it is characterized in that: 1 of described engaging lug is for staggering mutually, be arrangeding in parallel.
The thickness of the bottom of described fire grate segment body 3 is less than the thickness on its top.
Forward and backward engaging lug on the fire grate segment body of the present utility model is for staggering mutually, be arrangeding in parallel, and then the two sides of fire grate segment integral body are not straight, but broken line type, and then make the wind line between fire grate segment also be broken line type, thereby make the fire grate wind distributing face wide, more even, combustion efficiency is good; And can reduce coal leakage quantity, save a large amount of energy.The bottom of fire grate segment body is thinner than top in addition, thereby has alleviated weight greatly, reduces cost, and is the higher fire grate segment of a kind of cost performance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the upward view of Fig. 1.
Fig. 5 is result of use figure of the present utility model.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.Shown in Fig. 1～4, a kind of broken-line type travelling grate stoker sheet is provided with fire grate segment body 3, its front and rear portions is connected to engaging lug 1, and pin-and-hole 2 is arranged on the engaging lug 1, and 1 of described engaging lug is for staggering mutually, be arrangeding in parallel, during use, intersect and place, utilize fire grate long pin to be connected in series.The thickness of the bottom of described fire grate segment body 3 is preferably less than the thickness on its top.
Claims (2)
1. a broken-line type travelling grate stoker sheet is provided with fire grate segment body (3), and its front and rear portions is connected to engaging lug (1), and pin-and-hole (2) is arranged on the engaging lug (1), it is characterized in that: between described engaging lug (1) for staggering mutually, be arrangeding in parallel.
2. broken-line type travelling grate stoker sheet according to claim 1 is characterized in that: the thickness of the bottom of described fire grate segment body (3) is less than the thickness on its top.
