Seamless steel pipe surrounding type intermittent processor

Abstract

The invention relates to a seamless steel pipe surrounding type intermittent processor, and discloses an intermittent pre-cleaning processing device. The flow direction of high-pressure water flow is changed through a flow dividing ring, so that scouring water flow similar to vertical impact is formed to conduct scouring cleaning on a steel pipe, two sets of push rods are matched to move so that two semicircular flushing sleeves on the two sets of push rods can be intermittently spliced and separated, the water flow flushing direction at the outer wall of the steel pipe is intermittently changed, and the flushing effect is enhanced. The seamless steel pipe surrounding type intermittent processor is characterized in that a main flushing pipe is arranged on a base through a supporting seat, two containing boxes are arranged on the outer wall of the main flushing pipe and located on the two sides of the main flushing pipe respectively, the two ends of the main flushing pipe are of variable-diameter structures, the diameters of the variable-diameter structures decrease gradually towards the outer portion of the main flushing pipe, the longitudinal section of each containing box is in an arc shape, the arc length of one end of each containing box is smaller than that of the other end of the containing box, and the thickness of one end of each containing box is smaller than that of the other end of the containing box.

[0002] During the secondary processing and manufacturing of steel pipes, some stains, rust or impurities after the completion of the processing process will remain on the inner and outer walls. If these impurities are not cleaned up in time, these remaining stains and impurities will affect the subsequent coating. and the effective coverage of spray paint, and the second is that it will corrode the inner and outer walls of the steel pipe, causing corrosion damage to the steel pipe and affecting its normal service life. Therefore, it is necessary to clean the inner and outer walls of the steel pipe in time during the manufacturing process. Generally, the spray gun, nozzle and water flow or cleaning agent are used to align the nozzle and the pipe wall for simple flushing. However, when flushing in this cleaning method, the inner and outer walls can only be cleaned on one side at the same time. The flushing efficiency is low and the impact force is insufficient. , some stains on the inner wall of the steel pipe will still exist

In the prior art, the notification number CN104841673A discloses a cleaning device for the inner and outer walls of steel pipes, including a main pipe body, the rear end of the main pipe body is the liquid inlet end, the front end of the main pipe body is equipped with a nozzle with a coaxial center line, and the front end of the nozzle head is provided with a nozzle capable of connecting with the inlet. The liquid outlet connected to the liquid end forms a nozzle. In order to ensure that the inner and outer walls of the steel pipe can be cleaned at the same time, the device enters water from the mouth of the steel pipe and then flushes the water along the direction parallel to the central axis of the steel pipe. However, due to When flushing, the surface impurities on the outer wall of the steel pipe are parallel to the sand washing, and the scouring force on the outer wall is relatively small, and some stubborn impurities are easy to remove.
