Self-rotating type pipe-blocking prevention rubber ball

Abstract

The invention discloses a self-rotating type pipe-blocking prevention rubber ball. The parts, away from a rubber ball body, of supports make contact with each other to form cones, and front end protrusions of the supports are the top ends of the cones. The rubber ball body is cylindrical, surface protrusions are spirally distributed on the outer surface of the rubber ball body, and an inner hole and spiral inner blades are arranged in the rubber ball body. The number of the supports of piercing portions is two, or three or more, the number of the inner blades is one, or two or more, and a whole blade can be integrated or composed of several parts. The piercing portions at the two ends and the rubber ball body are made of polymer materials or polymer-based composite materials, and the difference between the density of the piercing portions at the two ends and the rubber ball body and the density of operating fluid is within 10%. The self-rotating type pipe-blocking prevention rubber ball can be used for deblocking a heat exchanging pipe which is blocked by impurities, the pipe is prevented from being blocked by the rubber ball, the ball collecting rate is improved, and resistance of the rubber ball is lowered; when fluid passes through the inner hole of the rubber ball, the heat transfer effect of the fluid is improved by the inner blades, and the surface protrusions on the rubber ball body have good removing effect to stubborn dirt on the inner surfaces of an inner ribbed tube and an inner threaded tube.

Description

technical field [0001] The invention relates to a cleaning rubber ball, in particular to a self-rotating anti-blocking pipe rubber ball used in pipelines. Background technique [0002] Shell-and-tube heat exchangers are widely used in electric power, petrochemical and other industries. During the operation of the heat exchanger, most of the heat exchange tubes will have dirt deposits, especially in condensers and water coolers that use circulating cooling water. , the effect of dirt is more serious. The existence of dirt will reduce the flow area of ​​the heat exchange tube, increase the flow resistance, increase the thermal resistance, deteriorate the heat transfer performance, increase the initial investment, increase the pump power consumption, and what's more, there will be corrosion under the scale, which seriously threatens the operation of the equipment Safety. There are many kinds of existing descaling methods, such as high-pressure water gun cleaning, drug-dosing ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the rubber ball is easy to cause pipe blockage when facing plastic cloth, weeds and other sundries, and the rubber ball has relatively large resistance during operation, the invention designs an anti-blocking pipe self-rotating rubber ball
