Specific embodiment:
The embodiments of the present invention is described further with reference to the accompanying drawings and embodiments:
In the description to the utility model, it is to be understood that indicating position or positional relationship are described as based on attached
Orientation or positional relationship shown in figure, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion
Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this
The limitation of utility model protection range.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is set
Set ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
A kind of bull-dozer fire-type exhaust tube, including upper cylinder 1 and lower cylinder 2, the bottom of the upper cylinder 1 are welded with mounting cup
3, the top of lower cylinder 2 is welded with lower mounting cup 4, and the upper mounting cup 3 and lower mounting cup 4 are that cylindric and internal diameter is identical, described
The internal diameter of upper mounting cup 3 and lower mounting cup 4 is greater than the outer diameter of upper cylinder 1 and lower 2 rest part of cylinder.Upper mounting cup 3 and lower mounting cup 4
Between form installation cavity, be successively fixed with interior flameproof enclosure 5 and outer flameproof enclosure 6 in installation cavity from top to bottom, the interior flameproof enclosure 5 wraps
3 ventholes 8 for including mounting plate A7 and being provided on mounting plate A7 are equipped at the venthole 8 and are weldingly fixed on mounting plate A7
The interior flame screen 9 of the tubular of bottom, the outer flameproof enclosure 6 include mounting plate B10, and the bottom mounting plate B10 is fixed with the outer of tubular
Flame screen 13,13 sets of the outer flame screen peripheries in all interior flame screens 9.The lower end of the upper mounting cup 3 and lower mounting cup 4
Upper end respectively be horizontally disposed with have flange, upper mounting cup 3 and lower mounting cup 4 are structure as a whole with its flange respectively, flange, installation
The mutual corresponding mounting hole 11 of preset quantity is had close to outer peripheral position on plate A7 and mounting plate B10, flange,
Mounting plate A7 and mounting plate B10 is fixedly connected by passing through the bolt 12 of mounting hole 11.It is equipped in the middle part of the mounting plate B10 logical
The open end in hole, the outer flame screen 13 is fixed on the periphery of mounting plate B10 middle through-hole.Interior flame screen 9 and outer flame screen 13
For the tubular structure surrounded with certain thickness plate, it is provided with the aperture of certain diameter on tubular structure, is dispersed throughout entire tubular
The surface of structure.Wherein interior flame screen 9 is three identical structures.
In use, the bottom of lower cylinder 2 is connect by clip or other modes with bulldozer engine silencer, installation is
It completes, no longer needs to that flameproof enclosure additionally is installed.In the presence of having Mars in exhaust, exhaust is entered in installation cavity, is first passed through outer
When the outer flame screen 13 of flameproof enclosure 6, it is small one by one by this that exhaust passage becomes gas vent small one by one, Mars or flame
Exhaust passage when, encounter other positions of aperture hole wall or outer flame screen 13, thermal loss occur and extinguishes, partially pass through outer
Flame screen 13 needs to be then passed through the interior flame screen 9 on interior flameproof enclosure 5 without the Mars of extinguishing, and then occurs during passing through
It collides and extinguishes, flame and Mars in exhaust stream is prevented to spray.Outer flame screen 13 is equipped with significantly with interior flame screen 9
Increase the rebuffed probability extinguished of Mars, it is ensured that flameproof effect.
The effect that 3 interior flame screens 9 are arranged is the surface area for considerably increasing interior flame screen 9 in a limited space, in turn
Exhaust is considerably increased by area, effectively reduces the inhibition of 5 pairs of interior flameproof enclosure exhausts, is avoided because setting multilayer is anti-
The network of fire and cause to be vented unsmooth problem so that this bull-dozer fire-type exhaust tube have stronger fire-proof function while it is true
Protect smooth gas discharge.
Due to using bolt 12 to connect between upper mounting cup 3, interior flameproof enclosure 5, outer flameproof enclosure 6 and lower mounting cup 4,
When needing to clean carbon deposit therein, bolt 12 can be unloaded, take out in flameproof enclosure 5 and outer flameproof enclosure 6 cleaned, it is convenient and
It is practical.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
