Description

Spiral propelling type pipe cleaner

Technical Field

The utility model relates to a pipeline cleaning device in the process of conveying natural gas and petroleum, in particular to a spiral propelling type pipe cleaner.

Background

The pig is an important tool indispensable to the pipeline industry. In the cleaning work of the oil and gas pipeline, sundries in the pipeline, including natural gas hydrate, household garbage, accumulated sediments, industrial wastes after construction, dead animal bodies and the like, can be cleaned by a pipe cleaner, scrap iron or burrs in the pipeline can be cleaned, and sometimes an owner also requires the pipe cleaner to check the ovality and the pipe wall corrosion condition of the pipe. When the pipeline is connected in a full-line mode, hydraulic tests are conducted on the pipeline. During the test, the individual steps of filling, draining and drying were also not pig-fed, but during commissioning and driving of the liquid transport pipeline, the liquid was also filled with pig-fed liquid. With the common commercial pig, the pipeline pig typically fails or becomes clogged while operating within the pipeline for a variety of reasons, such as: the pipe cleaner is clamped at the elbow, and the removed sediment is accumulated in front of the pipe cleaner to push the fluid to flow around the pipe cleaner, bend and deform the pipe cleaner and the like. The blocking of the pipe cleaner causes the flow of the pipeline to be reduced, even the whole pipeline is blocked, and serious consequences are caused. Although new points for improving the defects of the pipe pig exist so far, most of the pipe pigs have various defects, for example, a jet flow pipe pig suitable for a large-caliber gas pipeline, namely a product of patent No. CN2010207004797, improves a pipe pig brush head into a spherical structure, reduces the friction resistance, and greatly weakens the washing capacity of the pipe pig for refractory dirt. There is also a rotary brush pipe cleaner, the product of patent No. CN105665383A, which improves the operation mode of pipe cleaner to rotate pipe cleaner and improve the washing ability, but the structure of the rotary machine is too complex, and the manufacturing cost and maintenance cost are very high. The same type of pipe cleaner with a propeller and a lubricatable pipe wall, namely the product with the patent number of CN208033224, also applies the rotation mechanism of the pipe cleaner, and is provided with the propeller and the jet device, but the manufacture is also complex, and the service life of the propeller device is difficult to ensure in the complex pipeline cleaning process, so the maintenance cost of the product is worried. In summary, it is critical that the pipe cleaner not only needs to thoroughly solve the blocking problem of the pipe cleaner, but also needs to ensure high washing and brushing capability of the pipe cleaner, and simultaneously, the manufacturing cost and the maintenance cost are low. Therefore, based on the background, the product of the utility model can show the pipe cleaner which can clean sundries in the pipeline more thoroughly, can smooth the pipe wall, reduce the resistance and reduce the manufacturing cost and the maintenance cost of the pipe cleaner.

SUMMERY OF THE UTILITY MODEL

The utility model provides a spiral propelling pipe cleaner, which overcomes the defects of large friction resistance and easy blockage of the existing pipe cleaner, is convenient to operate and low in cost, and can thoroughly clean a pipeline.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: the upper spiral cleaning head, the plugging plate, the cleaning leather cup, the fixed base plate and the cleaning sheet of the pipe cleaner are sequentially fixed on a main connecting shaft in the middle of the pipe cleaner; the spiral cleaning head is connected with the plugging plate through a spiral cleaning head fixing shaft; the cleaning leather cup is fixed on the main connecting shaft of the pipe cleaner through a bolt and a nut and a fixed base plate, and the surface of the fixed base plate is provided with a plurality of screw holes; the device makes spiral cleaning hair take place to rotate under the effect of pipeline front and back pressure differential, cuts clearance stubborn barrier on the pipe wall, and clean leather cup and shutoff board afterwards, the piece is cleaned and residual debris on the pipe wall is further washd.

Preferably, the spiral cleaning head is designed to be a conical structure with an internal thread groove, a high-pressure medium flow acts on the surface of the internal thread groove to form a rotating torque taking a rotating shaft as a center in an operating state, the spiral cleaning head is connected with a fixed shaft of the spiral cleaning head, high-speed rotation can be realized under the action of the rotating torque, meanwhile, a forward impact force can be formed, dirt in a pipe is impacted, and friction loss is reduced.

Preferably, the cleaning leather cup is made of a compact, uniform and high-flexibility rubber material and is designed into a gradually-expanded round table shape, so that the friction resistance of the pipe cleaner in the pipeline is reduced;

preferably, the spiral cleaning head is connected with the plugging plate through a spiral cleaning head fixing shaft, the brush head and the plugging plate are both made of high-strength materials, the hardness is high, the toughness is good, and a layer of protective film is coated outside the fixed brush head, so that the corrosion can be slowed down;

preferably, the fixed base plate is provided with a plurality of screw holes through the surface of the main rotating shaft of the pipe cleaner and used for fixing and cleaning the leather cup;

preferably, the main connecting shaft of the pipe cleaner is hollow, a small-sized detecting instrument can be carried, and the main connecting shaft is integrally made of high-quality stainless steel products, so that the pipe cleaner is high in strength and good in corrosion resistance;

preferably, the cleaning leather cup and the fixed backing plate are fixed, and the cleaning sheet is fixed on the base of the main connecting shaft of the pipe cleaner through bolts and nuts.

The rotary propelling pipe cleaner for the gas transmission pipeline has the following beneficial effects:

(1) this product utilizes the high-pressure medium stream of the interior clear pipe of pipeline as power, need not to provide extra power supply, the more energy saving.

(2) The spiral cleaning head is of a special design structure, namely a conical spiral brush head with an inner spiral groove, high medium acts on the surface of the spiral groove to form a rotating torque taking a rotating shaft as a center, so that a pipe cleaner is driven to rotate at a high speed and form a forward impact force to impact dirt in the pipe, and friction loss is reduced; the brush head rotates to cut dirt in the pipe through the impact structure; and finally, residual impurity and dirt are further removed through a rear plugging plate, a plurality of layers of cleaning leather cups and cleaning sheets. By combining these four ways, the ability to impact the soil is effectively increased.

(3) To intractable dirt in the pipeline, traditional dredging pipe ware on the market often can take place to block up or take place to damage by pressure extrusion and warp, and to this product, because spiral cleaning head drives the dredging pipe ware high-speed rotatory in the pipeline, the special construction of brush head can easily cut the clearance to intractable dirt in addition, compares this product and brushes the effect better. In addition, the pipe wall after pipe cleaning becomes smoother due to the efficient washing effect, so that the friction resistance is reduced, and the effects of high efficiency and energy saving are achieved.
