A self-help ultrasonic descaling pig

Abstract

The invention discloses a self-powered ultrasonic scale removal tube cleaner. The self-powered ultrasonic scale removal tube cleaner comprises a body, and an ultrasonic generation apparatus, an electromagnetic induction power generation apparatus, a power supply apparatus and a protection apparatus, which are arranged on the body, wherein the body comprises a barrel and a cone; the ultrasonic generation apparatus comprises an ultrasonic generator; the electromagnetic induction power generation apparatus comprises a transmission connecting rod, an induction coil and a converter; the power supply apparatus comprises a packing cup and an impeller with a runner; and the protection apparatus is a metal protection cover, and the metal protection cover is provided with a leak flow hole. The tube cleaner is adopted as a carrier to be combined with the ultrasonic scale removal apparatus, so that the ultrasonic scale removal effect is more remarkable than the scale removal effect by only adopting the tube cleaner; and meanwhile, the self-powered ultrasonic scale removal tube cleaner carries a self-powered power generation apparatus, the automation degree is relatively high, scales are automatically removed, and the tube cleaner is only required to be transmitted and received by a tube cleaner receiving and transmitting barrel. Compared with a chemical tube cleaning way, the problem of changing the water quality is avoided, the phenomenon that a great amount of scales are dropped is avoided, and the tube cleaner plugging phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of descaling of water pipelines, in particular to a self-powered ultrasonic descaling pig. Background technique [0002] The scope of application of water pipelines is extremely wide, involving many fields such as life, agriculture, smelting industry, petroleum industry, etc. For large-scale water pipelines, during the long-term water delivery process, a layer of hard sediment-scale will be formed on the inner wall of the pipeline. This phenomenon is particularly important in industries with high hardness. The consolidated scale adheres to the pipe wall and is extremely difficult to remove, which will cause many problems, such as reducing the flow area of ​​the pipeline, resulting in a decrease in the delivery capacity of the water delivery pipeline; increasing the running resistance, resulting in a decrease in the delivery capacity of the water delivery pipeline, At the same time, the pump pressure will in...

AI Technical Summary

Problems solved by technology

[0004] Both of the above two methods of scale removal have certain disadvantages. The scale is firmly attached to the inner surface of the pipeline. Simply relying on the pig to remove the consolidated scale has no significant effect, and it is difficult to implement. There are also a lot of electromagnetic interference on site. This will greatly affect the acquisition of low-frequency magnetic field signals, and the signal acquisition workload of long-distance pipelines is also very huge

For chemical cleaning, on the one hand, some water quality has specific requirements and restrictions, and this method cannot be used at this time; on the other hand, chemical cleaning will produce some other large amounts of scale at the same time, which is likely to cause pipeline blockage
