Vertical descaling equipment for the inner wall of boiler tube

Abstract

The invention discloses vertical descaling equipment for the inner wall of a boiler tube. The vertical descaling equipment comprises a base, a first support and a top plate, wherein the first supportis arranged at the top of the base; a first hydraulic cylinder is arranged at the bottom of the base; a first piston rod is inserted in the top, penetrating through the bottom of the first support, ofthe first hydraulic cylinder; the top plate is arranged at the top of the piston rod; a movable ring is arranged at the bottom of the top plate; a telescopic rod is arranged in an inner cavity of themovable ring; and a second support is arranged at the top of the first support. According to the vertical descaling equipment, the telescopic rod is driven by the first hydraulic cylinder to move upand down, and a first gear is driven by a motor to rotate at the same time, so that a fixing block connected with the telescopic rod is capable of moving up and down while rotating at the edge of theinner cavity of a boil tube to be decaled, thereby facilitating descaling of the inner cavity of the boiler tube, the descaling efficiency is improved, and the vertical descaling equipment is suitablefor being use and popularized.

Description

technical field [0001] The invention relates to the field of boiler tubes, in particular to a vertical descaling device for the inner wall of boiler tubes. Background technique [0002] The boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The hot water or steam generated in the boiler can be directly used for industrial The heat energy required for production and people's life can also be converted into mechanical energy through steam power devices, or converted into electrical energy through generators. Some boilers are prone to scale formation in heat pipes after long-term use, which will seriously affect heat conduction and reduce thermal efficiency, and too much scale will hinder the flow of water in the boiler, which may cause boiler accidents. The scale in the boiler needs to be rem...

Problems solved by technology

[0003] The purpose of the present invention is to provide a vertical descaling device for the inner wall of boiler tubes, which solves the problem of using chemical reagents to soak the inner wall of boiler tubes and then using a long brush to remove the scales on the boiler tubes. It takes a long time to scrub the inner wall, consumes a lot of reagents, and the descaling efficiency is not good.
