Description

Assembled moveable grate for saving coal and eliminating smoke

The utility model relates to a kind of combustibilities such as Industrial Stoves and dining room cooking stove that are used to transform; the combined type coal-saving moving grate of protection environment; be applicable to various industrial pottery magnetic kilns; as the kiln of falling the cigarette, tunnel cave, pushed bat kiln, sinter forging stove, steel rolling furnace, hand burning Industrial Boiler and boiler for domestic, chemical reaction still, cooking stove field, dining room.

Existing various kiln majorities still adopt air blast under fixed grate gravity-flow ventilation or the stove, fiery upper coal feeding at present, and this draft type is used in fire slagging-off down, and fire coal can not fully burn, and can't eradicate smoke contamination.

Task of the present utility model overcomes exactly makes fire coal fully not burn in traditional kiln, can't eradicate the shortcoming of smoke contamination, and a kind of novel combined type coal-saving moving grate of designing.

Task of the present utility model is realized by following technical scheme:

The coal-saving moving grate is made up of wind chamber, wind pillow and fire grate, it is characterized in that fire grate by upper fire-grating (9), lower fire grating (11) anti-, just trench structure foundry goods snapping is formed.The top design of upper fire-grating (9) has a row upper fire-grating hole (10).There is a hasp (12) can be buckled on the clasp (13) of upper fire-grating (9) on the lower fire grating (11).

The operation principle of the utility model foundation is: this combined movable fire grate is to integrate gravity-flow ventilation and force ventilation, air blast enters preceding rear wind cavity with mechanical wind through the inlet air hole, in the common isobaric air compartment that constitutes of combined fire grate and left right wind pillow, from the wind hole of upper fire-grating, blow out one time wind, to guarantee coal-fired abundant burning, thereby it is fast to reach programming rate, efficiency of combustion height and the purpose of economizing on coal, in combustion process, volatilize a large amount of hydrocarbons and coal particulate, float diffusing in the upper furnace of high temperature, in the high temperature secondary wind that the wind pillow hole of left right wind pillow blows out, obtain burning for the second time, so just can reach the purpose of thorough coal-saving.

Coal is in combustion process, tiny coal particulate and lime-ash are fallen in the fire grate from the wind hole of upper fire-grating unavoidably, block for preventing the air channel, guarantee air feed, as long as open the hasp that connects upper and lower fire grate, just can remove the lime-ash and the long-pending rubbish thing that fall in the fire grate automatically, thereby guarantee the supply of a wind.

The combined movable fire grate directly communicates with the external world, and when left alone without help electricity, air still can enter coal-fired layer under fire grate, has kept fixed grate nature suction firing mode so again, can keep fire coal and burn away.

Existing kiln is installed has following characteristics behind the combined type coal-saving moving grate:

1, under the identical situation of grate area, fired coal combustion efficient height, programming rate is fast, and is faster more than 1/3 than former fire grate programming rate, thereby firing period is shortened greatly, and can improve the quality of products.

2, sufficient combustion is economized on coal significantly, not over-emitting black exhaust protection environment.After adopting this fire grate, the efficient of economizing on coal can reach about 20%, and flue dust blackness and concentration all can be lower than the national environmental protection primary standard.

3, fire grate is made up of two parts up and down, falls into coal dust the fire grate air channel, lime-ash from the wind hole and can remove at any time and amass the rubbish thing by opening lower fire grating, thereby guarantee that enough air quantity enter burning zone.

4, movable wind pillow can suitably be adjusted its height according to the different coals that the user adopts, so that reach the purpose of thorough smoke elimination.

5, the combined movable fire grate performance that has general fire grate again directly communicates with the external world, and air still can enter the combustion system that burning zone has kept the air draught of original kiln nature from the fire grate below when having a power failure.

Below just concrete enforcement power of the present utility model is further described.

The utility model combined type coal-saving moving grate, be fabricated structure, as shown in Figure 1, global shape is especially as the type of falling ∏, preceding rear wind cavity (2), there are four identical wind pillows (3) (8) both sides, are used for connecting left right wind pillow (6), (4), and the upper and lower position can change, and is used for regulating the height of left right wind pillow.The ∏ type that is shaped as of left side right wind pillow (6), (4), left right wind pillow inboard respectively is drilled with one group of wind hole (7), (5), is used to provide high temperature secondary wind.Upper fire-grating (9) is connected between preceding rear wind cavity (2), (8), be drilled with one group of fire grate hole (10) above the every upper fire-grating (9), be used to provide wind one time, lower fire grating (11) one ends are connected with a movable axis with rear wind cavity (8), upper and lower can be free movable, lower fire grating (11) other end links to each other with upper fire-grating (9) hasp with hasp (12).The cross sectional shape of upper fire-grating (9) and lower fire grating (11) is positive and negative trench structure.Preceding rear wind cavity, isobaric air compartment of the common formation of upper and lower fire grate and left right wind pillow.When the moving grate operate as normal, lower fire grating (11) upwards snaps on the clasp (13) that the side of upper fire-grating (9) protrudes with hasp (12), and upper fire-grating (9) constitutes the air channel with lower fire grating (11), forms one and overlaps complete combined fire grate.

The concrete course of work of the present utility model: as shown in Figure 2, this fire grate integrates gravity-flow ventilation and force ventilation, fire coal is added on the upper fire-grating (9), air blast enters front wind cavity (2), moving grate (9) with mechanical wind from inlet air hole (1), (11) air channel between, in rear wind cavity (8), left right wind pillow (6), the right wind pillow (4), mechanical wind provides even, a sufficient wind through the wind hole (10) of upper fire-grating to fire coal, and fire coal is fully burned.Coal-fired a large amount of volatile matters of separating out in combustion process mainly are carbon compound and the carbon particulate that does not have after-flame.In the burner hearth of high temperature, blow out under the effect of high temperature secondary wind, make the carbon compound and the thorough after-flame of carbon particulate of separating out, reach the purpose of coal-saving through left right wind pillow (6), the left right wind pillow hole (7) of (4), (5).

Fire grate is fallen into coal particulate and lime-ash from upper fire-grating hole (10) unavoidably and is blocked for preventing the air channel in real work, only need lower fire grating (11) is opened the long-pending rubbish thing that just can remove at any time in the air channel, thereby the operate as normal with fire grate of providing of a wind has been provided.

The moving grate (9) of combination, the bottom of (11) directly communicate with outside air, and when having a power failure, air still can enter burning zone under fire grate, have kept the combustion system of original fixed grate nature air draught so again, still can continue to keep burning.
