Description
Technical field
The utility model relates to the cleaning equipment of steel pipe inside and outside wall and its method for cleaning technical fields more particularly to a kind of use
In the small-caliber steel pipe inside and outside wall abrasive jet cleaning equipment that cleaning diameter is (DN70mm~DN400mm).
Background technique
Steel pipe is widely used in the engineering fields such as tap water, natural gas, petroleum, chemical industry, medicine, communication, electric power, ocean,
For intensity, the corrosion resistance etc. for enhancing steel pipe, it usually needs to the inside and outside plastic-coated that steel pipe carries out, and usually required before plastic-coated
Steel pipe is cleared up, i.e. the attachments such as clast, oxide skin, welding slag, scab, dirt of removal steel tube surface, makes the interior of steel pipe
Uniform roughness is presented in outer wall surface, the adhesive force and corrosion resistance of surface covering when enhancing sprays, in addition, also improving
The fatigue resistance of steel pipe.
Common cleaning equipment is shot-blasting machine, and existing shot-blasting machine can only individually clear up inner wall when clearing up steel pipe every time
Or outer wall is individually cleared up, the inside and outside wall of steel pipe cannot be cleared up simultaneously, and cleaning efficiency is lower, high production cost.In addition, in shot-blasting machine
In operation, the outer wall for clearing up steel pipe is easier, and conventional shot-blasting machine can be used, and when clearing up steel pipe inner wall, by steel pipe
Internal diameter and length restriction, available cleaning equipment is few.When clearing up the big steel pipe inner wall of diameter, because bore is big, shot is passed
Send the structure size of bracket that can design bigger, rigidity is big, deformation is small, and the impeller and blade dimensions of impeller head are big, shot
Linear velocity it is big, to beat effect good for throwing.When clearing up the inner wall for the small-caliber steel pipe that diameter is (DN70mm~DN400mm), in steel
Throwing paddle size in pipe is small, ball blast amount is low, and the length of general steel pipe is especially long, when the bore of steel pipe is small, it is desirable that
The structure radial dimension for transmitting bracket is small, but since steel pipe sizes are long, the rigidity that will cause transmission bracket in this way is small, amount of deflection is big,
Affect the effect of caliber pipe inwall cleaning.
Publication No. is a kind of caliber pipe inwall disclosed in the Chinese patent of CN 207448244U in existing technology
Shot-blast cleaning machine has the following deficiencies: 1, can only clear up the inner wall of steel pipe, cannot clear up steel pipe while clearing up steel pipe inner wall
Outer wall, cleaning efficiency is lower, high production cost.2, the supporting mechanism in equipment is in order to meet it relative to the existing circle of steel pipe inner wall
The movement of circumferential direction, and have the movement along steel pipe axial direction, rolling member and at least one axial direction are provided in circumferencial direction
Rolling unit, axial rolling unit interval are arranged on the outer peripheral surface of circumferencial direction rolling member, circumferencial direction rolling member packet
Include support inner ring, rolling bearing and support outer ring, the inner ring of rolling bearing and the mating connection of support inner ring, outer ring and support outer ring
It is cooperatively connected；Axial rolling unit is detachably connected with support outer ring.Supporting mechanism due to size-limited, in shot-blast apparatus
It has necessarily become smaller, and supporting mechanism needs the movement relative to the existing circumferencial direction of steel pipe inner wall, and must be along steel pipe axial direction side
To movement, therefore require rotary support mechanism to minimize while, meets the rolling in above-mentioned two direction, and it is difficult to manufacture and design
Degree is big, and the support construction is more complicated, high production cost, and relatively large sized, is not able to satisfy the clear of small diameter steel pipe
