Specific embodiment
In order that those skilled in the art more fully understand the utility model scheme, below in conjunction with the accompanying drawings and it is embodied as
The utility model is described in further detail for mode.
In a kind of specific embodiment, the utility model provides a kind of breeze blowing pipe-line system, refers to figure
1, the structure of the breeze blowing pipe-line system of the utility model embodiment offer is provided.
The breeze blowing pipe-line system that the present embodiment is provided includes：
Coal supply pipeline S1, the coal supply pipeline S1 is provided with to coal valve 2 near one end of coal feed point, near the one of coal outlet
End is provided with cue ball valve 3；
Scavenging pipeline S2, the scavenging pipeline S2 is connected with coal supply pipeline S1；Purging is provided with the scavenging pipeline S2
Valve 1；
Blow down branch road S3, one end of the blow down branch road S3 is connected with the cue ball valve 3, the other end with purging wind facies
Even, it is provided with blowoff valve 4 on the blow down branch road S3；
Rapid pollution discharging pipeline S4, it includes：Connection flexible pipe 7, detection control piper and the blowdown flexible pipe 9 being sequentially connected with；Phase
It is connected by snap joint 8 between adjacent pipeline；
Pressure gauge 6 and auxiliary ball valve 5 are provided with the detection control piper.
Above-mentioned pipe-line system can quickly clear up line clogging, and its process is as follows：
Close not allowed in pipeline to coal valve 2 and continue to block, blow down valve 1 is opened afterwards；Blowdown flexible pipe 9 is put into dirt discharge groove
It is interior；Purging wind and blowoff valve 4 are all opened, when pressure gauge 6 reaches purging wind normal value blowoff valve 4 is closed, opened rapidly auxiliary
Ball valve 5, the pressure in pipeline is many beyond external atmosphere pressure, so as to generate the debris that obstruction pipeline is taken in huge draft out of.
Auxiliary ball valve 5 is closed, if pressure gauge 6 is shown as cleaning the pressure of wind, illustrates that pipeline is unobstructed；If pressure gauge 6 is shown as 0, say
