Description

A kind of pipeline polishing dedusting dust hood

Technical field

The utility model relates to the cleaning dedusting technology field of floating pipe line polishing more particularly to a kind of offshore oil deliveries Pipeline polishing dedusting dust hood.

Background technique

Offshore oil delivery pipe generally has one of groove technique for grinding before welding, a large amount of due to that can generate when polishing pipeline Dust, iron filings impurity cause to be full of the sundries such as these dusts and iron filings between polishing and in entire processing workshop, these flue dust can be more It is unrestrained in air or be adsorbed between polishing on the wall of processing workshop.

When generate floating dust, the impurity such as iron filings are present in surrounding air, since the heat that generates when welding is to the work of crewman Make environment and health causes more serious harm, or even the phenomenon that crewman faints at work also occurs.

Or the impurity such as generation floating dust, iron filings can be sticked on wall, and wall is caused to turn yellow, and using general clear Clean method, such as be rinsed with water, it not can be removed the flue dust for the yellow being sticked on wall at all, cause the working environment of crewman more Badly, the cost of cleaning wall is on the other hand increased.

Summary of the invention

The purpose of the utility model is to provide a kind of pipeline polishing dedusting dust hood, floating dust, the iron filings etc. that polishing is generated Impurity is collected, it is avoided largely to diffuse the working environment for improving crewman in air, guarantees crewman's health, is reduced Between polishing with the cost of keeping a public place clean of processing workshop.

The technical scheme that the utility model is provided is as follows:

A kind of pipeline is polished dedusting dust hood, comprising: annulus, the annulus are hollow structure, and the ring Shape sleeve includes sleeve outer ring and sleeve inner ring, and the sleeve inner ring is equipped with several exhausting holes, and the sleeve outer ring is equipped with Blower mouth, the exhausting hole are connected to blower mouth by the inner cavity of the annulus, and blower passes through the blower mouth and ring The inner cavity of shape sleeve is connected to.

The utility model devises a kind of pipeline polishing dedusting dust hood, and floating dust, iron filings that pipeline generates when polishing etc. are miscellaneous Matter can be pumped into the impurity such as intracavitary in the annulus, to generate to polishing floating dust, iron filings by exhausting hole and be collected, and avoid It largely diffuses the working environment for improving crewman in air, guarantees crewman's health, reduces and protects between polishing with processing workshop Clean cost.

Preferably, several exhausting holes are evenly arranged on the sleeve inner ring.

Preferably, several exhausting holes are divided into the first exhausting hole and the second exhausting hole according to diameter, and described first Diameter of the diameter of exhausting hole less than the second exhausting hole；Second exhausting hole is provided with the sleeve inner ring at ground.

Some particles of the impurity such as floating dust, iron filings generated due to polishing are bigger, to can fall downwards, therefore, will cover Cylinder inner ring opens up the second exhausting hole at ground, so that the diameter of the second exhausting hole is greater than the diameter of the first exhausting hole, guarantees The impurity of bulky grain can be can smoothly enter into intracavitary in annulus by the second exhausting hole.

Preferably, the circumferential length of sleeve inner ring shared by all second exhausting holes accounts for the perimeter of entire sleeve inner ring 1/8~1/4.

Preferably, blast connection is equipped at the blower mouth of the sleeve outer ring, the inner cavity of the annulus passes through described Blast connection is connected to the blower；Drawing out type filter screen is equipped in the blast connection.

In above structure, larger impurity can be effectively filtered out by the way that drawing out type filter screen is arranged, is avoided larger miscellaneous Matter, which enters at blower, causes blower to damage, preferably protection blower, extends the service life of blower.

Preferably, the pipeline polishing dedusting dust hood further include: the annulus is arranged in hairbrush, the hairbrush Wherein one end, and the hairbrush is removably disposed around on the annulus, the free end of the hairbrush mutually is gathered to be formed One pipeline opening passed through for pipeline.

In actual work, pipeline to be polished is passed through from pipeline opening, so that hairbrush covers pipeline and sleeve inner ring Between gap, crewman far from hairbrush one end annulus at polish pipeline, polishing pipeline generate floating dust The inner cavity of annulus can be drawn by exhausting hole, a part in the impurity such as iron filings of larger particles can also be inhaled by exhausting hole Entering the inner cavity of annulus, is finally trapped in the bottom of the inner cavity of annulus, another part may splash around, this When, hairbrush can block the impurity of splashing, and avoiding impurity from issuing spark causes crewman injured.

Preferably, the sleeve outer ring is equipped with impurity drawer, the inner cavity company of the impurity drawer and the annulus It is logical；When pipeline polishing dedusting dust hood is in use state, the impurity drawer is located at the bottom of the sleeve outer ring.

By the way that the impurity drawer for collecting impurity is arranged in bottom, easily collect coacervating large particle dust or Iron filings etc. are outwelled after capable of extracting impurity drawer out when stopping work, more convenient.

Preferably, the pipeline polishing dedusting dust hood further include: pedestal；The universal wheel to contact to earth being set on pedestal； The height adjusting structure being set on the pedestal, the pedestal are connected by the height adjusting structure and the annulus It connects.

It can adapt to various sizes of pipe diameter by height adjusting structure, pipeline to be polished made to be located at annulus Middle position.

Preferably, the height adjusting structure is four support columns, is equipped with a slotted hole on the every support column, The long axis direction of the slotted hole is perpendicular to horizontal plane；The upper end of the support column is connect with the annulus；The pedestal Fixation hole is equipped at the position of the corresponding slotted hole, the fixation hole is connect by bolt with the slotted hole.

Preferably, the pedestal is equipped with 4 universal wheels, and at least 2 universal wheels are locking universal wheel and are located at described Pedestal it is ipsilateral.

When the device is set on the ship to jolt, ship can roll, at this point, grinding dust removing device also shake by left and right It shakes, and then efficiency of dust collection is affected, therefore by the way that 2 universal wheels are arranged to locking universal wheel, can fix device On ship, be unlikely to shake back and forth, buttress the device constantly without crewman, convenient for crewman polish polishing between with processing cart and Improve efficiency of dust collection.

A kind of pipeline provided by the utility model is polished dedusting dust hood, can bring it is following the utility model has the advantages that

The utility model devises a kind of pipeline polishing dedusting dust hood, which can be to the dust that polishing pipeline generates It is collected with impurity such as iron filings, influences body in processing workshop, avoiding it from being sucked by crewman between avoiding it from spreading in polishing Body health sticks and causes to be difficult on wall to clean, and reduces cost of keeping a public place clean between polishing with processing workshop indirectly.
