Description
Technical field
This utility model is related to steel pipe's production equipment technical field, specially a kind of scalable blowing device.
Background technology
During steel pipe's production, need to be cleaned steel duct process, removal is attached to the impurity on inwall.Example
Such as：A kind of coating steel pipe internal blowing device described in the Chinese utility model patent of Application No. 201310390572.0, including base
Seat and blowing device, the pedestal top is provided with roller-way, front apron and backboard is respectively equipped with before and after the blowing device, described
It was provided with for two communicating pipes between front apron and backboard, the communicating pipe is provided with gas tip.As the length of steel pipe has length to have
It is short, cause the coating steel pipe internal blowing device not adapt to the steel pipe of different length.
Utility model content
A purpose of the present utility model is to provide a kind of scalable blowing device, can be applied to the steel of different length
Pipe, blowing effect are good.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of scalable air blowing sets
Standby, including gas blow pipe, at least including two section sleeve pipes, described sleeve pipe is provided with the gas hole run through along its axis, institute to the gas blow pipe
State sleeve pipe to connect to form telescopic structure by socket mode, the junction of two neighboring described sleeve pipe is provided with prevents pipe interior air-flow
From the pressurized seal device that junction is revealed.
Preferably, the pressurized seal device includes seal closure and air pressure output precision, the seal closure is set in phase
The junction of adjacent two described sleeve pipes simultaneously forms annular seal space with the outer wall of described sleeve pipe, and the sealing is covered with and the annular seal space
The socket of connection, being provided with the socket makes its sealing structure with the outer wall sealing of described sleeve pipe.
Preferably, the air pressure output precision includes appendix and the blower fan connected with the annular seal space.
Preferably, the air pressure of the sealing intracavity is more than or equal to the air pressure in gas blow pipe.
Preferably, described sleeve pipe is conical pipe, the outside diameter of described sleeve pipe front end is outer less than described sleeve pipe rear end
Circular diameter, the gas hole are the bellmouth being adapted with described sleeve pipe profile；The maximum outside diameter of previous described sleeve pipe, greatly
In the minimum diameter and the maximum gauge less than gas hole of the gas hole in latter described sleeve pipe.
Preferably, the sealing structure includes loop connecting portion and elastic seal ring, the elastic seal ring is arranged on
The inside of the seal closure, the loop connecting portion are connected between elastic seal ring and socket.
Preferably, the elastic seal ring with diameter greater than the socket and the cylindrical maximal clearance of described sleeve pipe.
Preferably, the loop connecting portion is made up of flexible material, and the loop connecting portion is from socket to sealing
The internal bending of cover.
When appendix is to sealing intracavity gas transmission, sealing intracavity air pressure increase, until more than or equal to gas blow pipe when blowing
Interior air pressure so that the air-flow of sealing intracavity is flowed in gas blow pipe by the gap of cannula connection, prevents the gas in gas blow pipe
Flow to outward leakage and reduce current rate；Sealing the increase of intracavity air pressure simultaneously causes loop connecting portion outwards to expand, and drags bullet
Property sealing ring be displaced outwardly, as socket and the cylindrical gap of sleeve pipe are less than the diameter of elastic seal ring, therefore elastic packing
Circle can be blocked in socket and the cylindrical gap location of sleeve pipe, and so as to produce sealing effectiveness, the air pressure for sealing intracavity is bigger, sealing effect
Fruit is more preferably.
The beneficial effects of the utility model：Gas blow pipe of this utility model by setting stretching structure, can be applied to not
With the steel pipe of length, use range is expanded, while pressurized seal device is provided with cannula connection, effectively can prevent
Air-flow in gas blow pipe out, improves the sealing property of gas blow pipe, it is ensured that air blowing intensity, carries from the gap leakage of junction
High blowing effect.
