Abstract

A bullet-type self-rotating pipe cleaner comprises a bullet-type foam head, a framework, a leather cup with holes and a fastening device. The side surface of the cylinder of the foam head is provided with a spiral groove, so that the foam pipe cleaner can move axially in the pipe and can rotate by flowing fluid through the groove. The tail part is combined with a detachable leather cup with a hole, so that the defect that the complete pipe wall cannot be scraped in the gap during cleaning the front-end foam pipe is overcome. Simultaneously, the dirt that blocks before the pipe cleaner can shift to behind the pipe cleaner through concave channel and leather cup hole for the pipe cleaner passes through smoothly, is difficult for blocking at the intraductal card. The bullet-type self-rotating pipe cleaner provided by the utility model can automatically rotate and scrape the pipe wall so as to peel and stir stains on the pipe wall and reduce blockage. For the pipeline with more stains accumulated on the pipe wall, the bullet-shaped self-rotating pipe cleaner can achieve a good pipe pre-cleaning effect and has a long service life.

Description

Bullet type self-rotating pipe cleaner

Technical Field

The utility model relates to the field of pipeline cleaning, in particular to a pipe cleaner which can be used for stripping silt, dust, metal fragments and dirt in crude oil and natural gas pipelines and has self-rotation performance and can avoid blockage.

Background

The component discovery of the pigging clear-out material of a certain crude oil pipeline and a natural gas pipeline in China is analyzed: the crude oil pipeline purge is mainly composed of iron oxides, silt, wax, colloid, asphaltene, etc., while the natural gas pipeline purge is mainly composed of iron oxides, silt, condensate, etc. These stains adhere to the inner walls of the pipeline, preventing the normal flow of crude oil and natural gas. Although some pipe cleaners such as the one disclosed in patent No. CN212216501U can clean pipes efficiently, the pipe walls are scratched by the blades, the service life of the pipes is reduced, and the pipe cleaners are not suitable for all pipes.

The rotating pig can enhance the tube cleaning effect, and most of the prior pigs can only move along the axial direction of the tube wall and are difficult to move along the circumferential direction. Although a rotatable pipe cleaner, for example, CN209918500U patent, is a spiral propelling pipe cleaner for natural gas pipelines, it needs a complicated spring structure, and some pipes need additional power, which is not convenient enough. The pipe cleaner with the propeller and capable of lubricating the pipe wall is also used for rotating the pipe cleaner, such as a product with the patent number CN208033224, the propeller and the jet device are arranged, but the manufacture is complex, and the propeller device is difficult to ensure the service life in the complex pipeline cleaning process, so the maintenance cost of the product is very high

At present, the existing pipe cleaner is easy to block in the pipe. As with the foam pig of patent No. CN206009362U, once the front soil builds up, the pig cannot advance. In addition, the design function is multiple, the aim is to clean the oil pipeline, or the pipeline is cleaned under various environmental conditions, for example, the patent number CN113007493A is a pipeline diameter measuring and cleaning device, although the adaptability is strong, and the device can be used for multiple purposes, due to the characteristic that the dirt is blocked in the pipeline, the dirt and a pipeline cleaner are simply erased from the pipeline wall and pushed forward, so that the dirt and the pipeline cleaner are easily clamped in the pipeline, and if devices with other functions are added, the blockage is easily caused.

SUMMERY OF THE UTILITY MODEL

Therefore, based on the background, the utility model discloses a can realize autogyration, clean debris in the pipeline comparatively thoroughly, be difficult for causing intraductal card stifled, and low cost of manufacture and cost of maintenance's bullet head formula autogyration dredging pipe ware will be shown. The front end of the framework is connected with a polyurethane bullet-shaped foam head with a spiral groove, and the rear end is connected with a leather cup with pores.

Preferably, the foam head is made of polyurethane materials, the shape of the foam head is a combined shape of a cylindrical truncated cone with equal bottom, and a plurality of spiral grooves are formed in the side face of the cylindrical section.

Preferably, the foam head is in interference fit with the inner diameter of the pipeline.

Preferably, the spiral grooves are 4 1/4 circles and are uniformly distributed along the circumferential direction of the foam head at 90 degrees, and the bottom diameter is smaller than the inner diameter of the pipeline.

Preferably, the framework is a steel material component, is hollow and cylindrical, has a closed bottom end, is connected with the foam head at the front end and is connected with the leather cup through a bolt at the rear end.

Preferably, the leather cup is made of rubber materials and is provided with a plurality of uniform pores.

Preferably, the number of the pores is 4, the pores are uniformly distributed on the leather cup, and the outer edge of each pore is smaller than the inner diameter of the pipeline.

Preferably, the leather cup is in interference fit with the inner diameter of the pipeline.

The utility model has the beneficial effects that: the foam head is shaped like a bullet head and is provided with a spiral groove, and high medium flow can only pass through the groove. The high medium flow acts on the spiral groove to enable the foam head to form a rotating torque taking a self rotating shaft as a center, so that the pipe cleaner is driven to rotate in the pipe automatically, the dirt in the pipe is stirred, and meanwhile the dirt can be discharged from the groove. Secondly, the leather cup can clean the pipe wall which is not cleaned at the groove of the foam head, and the dirt can be leaked out through the pores in the leather cup. And the leather cup can be disassembled and replaced after being worn, so that the service life of the pipe cleaner is prolonged. And fourthly, the dirt can be separated from the pipe wall and discharged to the pipe cleaner, and the pipe cleaner is prevented from being blocked in the pipe. The autogyration function has increased the ability that the dirt was got rid of to the pig effectively, and bullet head formula autogyration pig need not to provide extra power supply and just can realize rotatoryly, the energy saving more.
