Abstract
The utility model relates to the foreign matter cleaning plant in steel pipe, particularly a kind of steel pipe inner wall blow device.It comprises the tracheae of a hollow, and one end of this tracheae connects source of the gas; It is characterized in that: the other end of this tracheae connects a fork formula blow head, and this fork formula blow head has two or more inflatable mouth direction and stretches into the contrary air blowing arm in direction with tracheae, and the distance of each air blowing arm outermost end is less than the internal diameter of steel pipe.It has advantages such as saving tolerance, the saving energy, purging area coverage is large, purging speed is fast.
Description
Technical field
The utility model relates to the foreign matter cleaning plant in steel pipe, particularly a kind of steel pipe inner wall blow device.
Background technology
In steel pipe external coating industry, for obtaining the reserved length of pipe end and effect, need to carry out pipe end bruting process.Pipe end bruting process is mechanically, and pipe end outer wall place coating polishing is clean, then obtains length and the angle of regulation requirement.In pipe end bruting process, the coating debris of formation, very easily flies into pipe end in the steel pipe of the 2m degree of depth, and is attached to steel pipe inner wall formation pollution.
Existing solution has polishing in the mouth of pipe, place sponge plug and uses compressed air to purge.
Wherein: sponge plug drawback, for increasing mounting or dismounting operation, adds workload or manpower.
Wherein: use compressed air to carry out the mode that purges as shown in Figure 1, 2.It mainly extend into steel pipe by the tracheae 1 of a hollow from one end of steel pipe, and one end of this tracheae 1 connects source of the gas, the other end is inflatable mouth, and the other end of the foreign matter 2 in steel pipe from steel pipe can blow out by this inflatable mouth.It covers end, by being attached to the chip of pipe end to 2m degree of depth inwall, by Air Force, running about 10m distance, blowing out from another pipe end, air large usage quantity in pipe; As steel pipe inner wall has water, then purge effect poorer.In addition, because the inflatable mouth relative aperture of tracheae 1 is more limited, therefore its regional compare of covering of blowing is narrow and small, is unfavorable for improving the efficiency purged.
Summary of the invention
The purpose of this utility model is to provide a kind of steel pipe inner wall blow device, mainly solves the technical problem existing for above-mentioned prior art, and it has advantages such as saving tolerance, the saving energy, purging area coverage is large, purging speed is fast.
For what solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of steel pipe inner wall blow device, it comprises the tracheae of a hollow, and one end of this tracheae connects source of the gas; It is characterized in that: the other end of this tracheae connects a fork formula blow head, and this fork formula blow head has two or more inflatable mouth direction and stretches into the contrary air blowing arm in direction with tracheae, and the distance of each air blowing arm outermost end is less than the internal diameter of steel pipe.
Described steel pipe inner wall blow device, is characterized in that: this fork formula blow head has three air blowing arms, and three blow afloat arm and are circumferentially equally spaced.
The utility model has the advantage of:
1, the utility model can ensure to use less tolerance, and shorter time and faster speed complete steel pipe inner wall foreign matter piping and druming work.
2, the formula blow head that diverges in the utility model has two or more inflatable mouth direction and stretches into the contrary air blowing arm in direction with tracheae, compared with prior art, has both increased break-in shower nozzle, changes Air blowing direction again.Be particularly conducive to the foreign matter that cleaning is piled up in distance steel pipe port not distant positions.
Accompanying drawing explanation
Fig. 1 is the structural representation that existing use compressed air carries out purging.
Fig. 2 is the partial enlarged drawing in A portion in Fig. 1.
Fig. 3 structural representation of the present utility model.
Fig. 4 is the partial enlarged drawing in B portion in Fig. 3.
Detailed description of the invention
Refer to Fig. 3,4, the utility model discloses a kind of steel pipe inner wall blow device.As shown in the figure: it comprises the tracheae 1 of a hollow, one end of this tracheae 1 connects source of the gas; The other end of this tracheae 1 connects a fork formula blow head 3, and this fork formula blow head 3 has two or more inflatable mouth direction and stretches into the contrary air blowing arm in direction with tracheae 1, and the distance of each air blowing arm outermost end is less than the internal diameter of steel pipe.
As preferred structure, this fork formula blow head 3 has three air blowing arms, and three blow afloat arm and are circumferentially equally spaced.Certainly, the quantity of its air blowing arm also can increase further, from result of use, and minimum use two.
As alternate configurations, the direction of air blowing arm and the angle of steel pipe axis are 0-90 °.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
