The condition of putting plays critically important effect, and still, after a period of use, the inner wall of these oil smoke exhaust ducts will gather
Grease, since grease is inner wall of the product in air hose, be not easy by it is found that and it is ignored, often because of Mars or high-temperature flue gas
Into and these greases that ignite.Once grease is in air draft combustion inner pipe, and air-exhausting duct is often the discharge that hoists, so right
For the grease of burning, air-exhausting duct plays the wind-drawing effect of chimney, so that grease the more burns the more prosperous, easily leads to fire.
Utility model content
The purpose of the utility model is to overcome defects present in traditional oil smoke exhaust duct, provide a kind of fire protection pipe
Road.
The purpose of this utility model is achieved through the following technical solutions: a kind of fire prevention pipeline, including mutual by connecting tube
The first smoke exhaust pipe and the second smoke exhaust pipe of connection, and the separating mechanism being arranged in connecting tube；The separating mechanism includes setting
The annular retaining ring inside connecting tube is set, the partition panel on annular retaining ring, one end and annular are movably arranged on by rotating mechanism
The reset spring that retaining ring connection, the other end and partition panel connect, and the traction mechanism being connected between partition panel and connecting tube；
The partition panel can be overturn around rotating mechanism, and separate or be connected connecting tube.
Further, the rotating mechanism includes the two installations protrusion being arranged on annular retaining ring side wall, is connected to two
Between a installation protrusion and the shaft that is able to rotate；The partition panel is connect with shaft.
The traction mechanism includes the fixed block being arranged in inside connecting tube, and one end connect with partition panel, the other end and solid
Determine the drawstring of block connection.
It is provided with buckle on the annular retaining ring, the card slot matched with buckle is provided on the partition panel；It is described every
Buckle is mutually fastened with card slot when disconnected plate partition connecting tube.
The utility model compared with the prior art, have the following advantages that and the utility model has the advantages that the utility model in normal use
Partition panel is pulled into connecting tube lower wall by drawstring when under state, oil smoke is discharged normal through pipeline at this time, when occurring in pipeline
When fire, drawstring is blown, and is overturn every after plate due to the pulling force effect of reset spring, so that connecting tube be separated, is prevented fire
Gesture sprawling.

Specific embodiment
The utility model is described in further detail below with reference to embodiment, but the embodiments of the present invention is simultaneously
It is without being limited thereto.
Embodiment
As shown in Figure 1, the fire prevention pipeline of the utility model, including pass through first smoke exhaust pipe, 1 He interconnected of connecting tube 2
Second smoke exhaust pipe 3, and the separating mechanism being arranged in connecting tube 2.First smoke exhaust pipe 1 and the second smoke exhaust pipe 3 pass through spiral shell
Bolt is flexibly connected with connecting tube 2, therefore can mutually be dismantled between three, in order to safeguard to separating mechanism.In use,
Oil smoke is successively discharged after the second smoke exhaust pipe 3, connecting tube 2 and the first smoke exhaust pipe 1.
Specifically, the separating mechanism includes the annular retaining ring 4 being arranged in inside connecting tube 2, set by rotating mechanism activity
Set the partition panel 7 on annular retaining ring 4, the reset spring that one end is connect with annular retaining ring 4, the other end and partition panel 7 connect
12, and the traction mechanism being connected between partition panel 7 and connecting tube 2.The annular retaining ring 4 can by welding and even
Adapter tube 2 connects.In specific design, the annular retaining ring 4 it is interior, and fixed ring is provided on partition panel 7, reset spring 12
Both ends catch on the fixed ring on annular retaining ring 4 and partition panel 7 respectively, the fixed form of spring is more typical in the prior art,
No longer excessive statement.
In addition, rotating mechanism includes the two installations protrusion 6 being welded on 4 side wall of annular retaining ring by welding,
It is connected to the shaft 5 between two installation protrusions 6 and being able to rotate, the partition panel 7 and shaft 5 are welded.This two installations are convex
It rising and is provided with mounting hole on 6, shaft 5 passes through the through-hole in two installation protrusions 6, and shaft drops out installation protrusion in order to prevent,
Nut can be set in both ends of the shaft, and by above structure, which can follow shaft 5 to rotate, and the structure of rotating mechanism is as schemed
Shown in 3.
The traction mechanism includes the fixed block 9 being welded on inside connecting tube 2, one end connect with partition panel 7, the other end with
The drawstring 8 that fixed block 9 connects.
When under normal operating conditions, drawstring 8 pulls down the downside that partition panel 7 makes partition panel 7 close to connecting tube 2, connects at this time
Adapter tube 2 is in opening state, and reset spring 12 is in tensional state, as shown in Figure 1.When occurring fire in pipeline, drawstring 8
It is disconnected by burning, due to the reset response of reset spring 12, partition panel 7 is quickly pulled, overturns partition panel 7 and cover to close connecting
The end of pipe 4, and then separate connecting tube 4, prevent fire spreading.
After smoke exhaust ventilator is discharged and transmits a distance, oil smoke temperature will be greatly reduced oil smoke, usually only 30~
60 DEG C, therefore nylon rope can be used in the drawstring 8, can blow nylon rope after kindling.
As a preference, being provided on the partition panel 7 as shown in Fig. 2, be provided with buckle 10 on the annular retaining ring 4
The card slot 11 matched with buckle 10.After drawstring 8 is blown, 7 fast fastening of partition panel, and buckle 10 and mutually detained with card slot 11
It closes, so that it is stronger to fasten partition panel 7.
As a preference, the partition panel 7 is provided with ring type seal close to the side of annular retaining ring 4, make partition panel 7 with
The closer fitting of connecting tube；The ring type seal can be used fire-proof sponge material and be made.
As described above, the utility model can be implemented well.
