Cross-sectional area in horizontal plane；Multiple air vents are provided with the top and bottom of housing.
Preferably, upper hole is circular port, and lower opening is rectangular opening.
Preferably, the aperture of circular port is 6-8mm；The aperture of air vent is 5-8mm；The specification of rectangular opening is：A length of 45-
55mm, a width of 3-4mm.
Preferably, multiple circulation air holes are provided with the tube wall of " V " shape pipe.
Preferably, the aperture of circulation air holes is 4-6mm.
Preferably, being provided at both ends with for housing takes pin.
Preferably, pin is taken to be angle bar or take the cambered surface that the bottom surface of pin is upward indent.
In the above-mentioned technical solutions, the funneling specifically used process of biological particles stove grate of " V " shape that the present invention is provided
It is as follows：First, the funneling biological particles stove grate of " V " shape is placed in the furnace bottom of hot-blast stove；Then, solid fuel is placed in
The top of housing is burnt, in combustion, using two upper holes in cross-sectional area in horizontal plane and less than lower opening
Cold air is enabled to sequentially pass through lower opening, " V " shape the characteristics of the cross-sectional area and hot-air in horizontal plane are moved upwards
Pipe and upper hole enter the inside of solid fuel and then can provide enough oxygen for the burning of fuel；Meanwhile, solid fuel
The hot gas produced in combustion process also can self-ventilation hole to the moved beneath of grate, and then cause the heat that produces in combustion process
Amount self-ventilation hole disperses；Also, the special setting in upper hole and the aperture of lower opening, which has, inhales wind action, and then the cold air flowed through
Also it can play a part of reducing the temperature of grate, and then the deformation or damage of grate can be prevented.
Other features and advantages of the present invention will be described in detail in subsequent embodiment part.

Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
In the present invention, in the case where not making opposite explanation, " upper and lower, top, bottom " etc. is included in the noun of locality in term
Only represent orientation of the term under normal service condition, or be skilled artisan understands that be commonly called as, and be not construed as pair
The limitation of the term.
The invention provides a kind of funneling biological particles stove grate of " V " shape, as Figure 1-3, including：Housing 1；Shell
Being internally formed in cavity, cavity for body 1 is provided with multiple " V " shape pipes 2, and the top of " V " shape pipe 2 and housing 1 is formed with two
Upper hole 3, the bottom of " V " shape pipe 2 and housing 1 is formed with lower opening 4；Two upper holes 3 are in cross-sectional area in horizontal plane and are less than
Lower opening 4 is in the cross-sectional area in horizontal plane；Multiple air vents are provided with the top and bottom of housing 1.
The funneling specifically used process of biological particles stove grate of above-mentioned " V " shape is as follows：First, it is " V " shape is funneling
Biological particles stove grate is placed in the furnace bottom of hot-blast stove；Then, the top for solid fuel being placed in into housing 1 is burnt,
In combustion process, using two upper holes 3 in cross-sectional area in horizontal plane and less than lower opening 4 in the cross-sectional area in horizontal plane
And hot-air the characteristics of move upwards the characteristics of so that cold air can sequentially pass through lower opening 4, " V " shape pipe 2 and upper hole 3
Into the inside of solid fuel and then enough oxygen can be provided for the burning of fuel；Meanwhile, during solid fuel ignition
The hot gas of generation also can self-ventilation hole to the moved beneath of grate, and then cause the heat self-ventilation hole that produces in combustion process
Disperse；Also, the special setting in upper hole 3 and the aperture of lower opening 4, which has, inhales wind action, and then the cold air flowed through can also rise
To the effect of the temperature of reduction grate, and then the deformation or damage of grate can be prevented.
In the present invention, the concrete shape of upper hole 3 and lower opening 4 can be selected in wide scope, for example circular hole, square
Hole, diamond hole or other irregular holes, but for the effect of the ventilation and the cooling that further improve this grate, it is preferable that
Upper hole 3 is circular port, and lower opening 4 is rectangular opening.Thus, rectangular opening can utilize its larger aperture and then make it that cold air is quick
Ground enters lower opening 4, and then cold air is discharged from the less upper hole 3 in aperture, wherein, circular port energy during cold air is discharged
Enough so that on the one hand cold air formation vortex, the vortex can play a part of quickly cooling, another even more important aspect
It is that vortex can play obvious percussion to solid fuel, so that solid fuel can sufficiently burn.
It is circular port in upper hole 3, in the case of lower opening 4 is rectangular opening, the specific size of upper hole 3 and lower opening 4 can also be
Selected in wide scope, in order that the size that must be gone up between hole 3 and lower opening 4 can be matched preferably, and then cause upper hole 3 with
Hole 4 can play more preferable air draught and row's wind action, it is preferable that the aperture of circular port is 6-8mm；The aperture of air vent is 5-
8mm；The specification of the rectangular opening is：A length of 45-55mm, a width of 3-4mm.
In addition, the effect of ventilation and the cooling in order to further improve the grate, it is preferable that on the tube wall of " V " shape pipe 2
It is provided with multiple circulation air holes.The circulation air holes can not only cause the cold air in " V " shape pipe 2 and the cavity in housing 1
Heat exchange is formed between hot-air, and then the heat in housing 1 is discharged by cold air, and then is caused in housing 1
Temperature reduction so that play reduction grate temperature effect.On the other hand, also can between two adjacent " V " shape pipes 2
The circulation of beneficial cold wind is formed, so as to provide more enough cold airs for solid fuel, and then causes solid fuel
Can fully it burn.
Wherein, in the above-described embodiment, the aperture of circulation air holes can be selected in wide scope, in order to further carry
The practicality of the high grate, it is preferable that the aperture of circulation air holes is 4-6mm.The circulation air holes can either play raising wind circulation
Effect, while can also play a part of preventing excessive burning ashes obstruction " V " shape pipe 2, by circulating air holes discharge combustion
Ashing cinder.
In addition, installation and dismounting in order to further be easy to grate, it is preferable that pin 7 is taken in being provided at both ends with for housing 1.
Thus, as long as just can easily and quickly realize the installation and dismounting of grate by taking pin 7.
On the basis of the above, for the effect of the ventilation and the cooling that further improve grate, it is preferable that take pin 7
It is angle bar or the bottom surface for taking pin 7 is the cambered surface of upward indent.Like that, gap certainly will be formed by taking between pin 7 and furnace bottom, then cold
Air can also be entered in hot-blast stove by gap, thus further increasing the effect of ventilation and the cooling of grate.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the present invention, a variety of letters can be carried out to technical scheme
Monotropic type, these simple variants belong to protection scope of the present invention.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the present invention to it is various can
The combination of energy no longer separately illustrates.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
The thought of invention, it should equally be considered as content disclosed in this invention.
