Description

Energy-conserving and environment-protective fire grate body

The utility model relates to the coal-fired fire grate of boiler kiln, refers to that especially a kind of combustion case is better, the coal-fired fire grate that service life is long.

The fire grate that existing boiler, kiln are used, its material is generally cast iron, only at 400 ℃ or more use under the low temperature, its fire grate, fire bars scale error are big, rough surface, the slit is big between fire grate, leak coal, leak ash and inleakage big, contaminated environment; Fire grate high-temperature region in service life is less than one month, low-temperature space also only about three months, and can only disposablely use, energy resource consumption is big.

The purpose of this utility model provide a kind of minimizing leak coal, high temperature resistant, the life-span is long, combustion case better helps energy-conservation and boiler, kiln fire grate body environmental protection.

The purpose of this utility model is achieved in that energy-conserving and environment-protective fire grate body, it includes the fire bars of different size, the fire grate of multiple style, and constitute by fixture, connecting piece and driving member, it is characterized in that, the fire grate body partly is made up of mid portion and side, mid portion includes fire bars, fire grate, side clamping plate and middle clamp plate, and by cylinder, pull bar and sleeve constitute.

Above-mentioned design, because fire bars, fire grate and side clamping plate, middle clamp plate all adopt the precision casting of nickel chromium triangle material heat-resisting alloy steel, not only precision, surface smoothness are higher, coal is leaked in favourable minimizing, energy savings prevents contaminated environment, and high temperature resistant, service life can be for 2-3, and old fire bars can also be recycled.The maintenance of in addition stopping transport can reduce, so economic benefit, social benefit all increase greatly.

Below by drawings and Examples the utility model is remake further additional and drawing explanation.

As shown in Figure 1: be the utility model fire grate body mid portion, it includes fire grate 1, side clamping plate 2, middle clamp plate 3, and is made of cylinder 4, pull bar 5 and sleeve 6.This Fig. 1 just partly analyses and observe its shape structure of expression, and well-known grate area depends on the size of burner hearth, and promptly the evaporation capacity of boiler increases grate area as need, and fire grate 1 that can identical shaped structure is to vertically being that extend on Fig. 1 right side, and is omitted among Fig. 1.

As shown in Figure 2: the utility model fire grate body side part, it is provided with tabular fire grate 7, moving grate 8 and fixed grate 9, and is combined by fixture, connecting piece and driving member, and wherein moving grate 8, also look the needs of grate area and row more than can being provided with.

Shown in Fig. 3,4,7,8, it has shown the shape structure of the utility model side clamping plate, middle clamp plate, and its underpart is equipped with to connect uses through hole.

Among Fig. 5,61 ', 1 among Fig. 9,10 " be the embodiment of fire grate 1.

Shown in Fig. 5,6: it has shown the embodiment one shape structure of the utility model fire grate 1.

Shown in Fig. 9,10,11,12: it has shown shape and the structure of another embodiment of the utility model fire grate 1.As seen from the figure: constitute the fire bars of this kind fire grate 1, also claim fire grate segment, wherein subordinate's end is established the inclined-plane that is inclined-plane 10 or band ladder, constitutes the inclined hole that fire grate contains ventilation inclined hole or band ladder thus.In addition, from Figure 11,12 as can be known, the fire bars of this kind fire grate 1 also can be divided into pattern in two: the one, and its side is established and is inclined-plane 11,12; The 2nd, be the inclined-plane 11,12 except that establishing, one of them 12 upper end, inclined-plane is provided with lug 13, thus, adopts the fire bars of the former pattern, can constitute " seamless Shanghai row ", and adopts latter's pattern can constitute " the seam fire grate is arranged ", to satisfy the needs of different combustion cases.

Shown in Figure 13,14,15: it is a fire grate body side part, i.e. the structure situation of tabular fire grate 7 among Fig. 2.

Shown in Figure 16,17,18: be the structure situation of moving grate among Fig. 28.

Shown in Figure 19,20,21: be the structure situation of fixed grate among Fig. 29.

As can be seen from Figure 17: the lower end, fire bars middle part of moving grate 8 is also established and is inclined-plane 14.

As can be seen from Figure 20: the lower end, fire bars middle part of fixed grate 9 is also established and is inclined-plane 15.

In a word, therefore the utlity model has following feature:
