Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a pipe foreign matter removing device, and more particularly, to a pipe foreign matter removing device capable of effectively removing foreign matter such as sludge in a pipe.

Various types of piping used in industrial infrastructures are subject to deterioration, corrosion and sedimentation over time. This can reduce the flow of fluid through the piping, causing malfunctions and sometimes leading to accidents. In other words, the corrosion of piping is promoted due to chemical substances, and many foreign substances accumulate inside the piping, which hinders the flow of the flow rate, so that a serious accident may occur due to the deterioration of function and malfunction of the piping.

Particularly, since the BFG (Blast Furnace Gas) or CFG (Corex Furnace Gas) pipe is a passage for transferring the gas generated by burning the coal component, the carbon residue gas residue accumulates over time in the pipe. The pipes of several Km length are installed in each factory of the steel mill and supply the generated gas.

If you do not clean the inside of the piping regularly, deposits accumulate, which impedes the flow of the gas, resulting in loss of pressure of the gas supplied to each plant. In addition, sedimentation of sludge containing carbon and various iron components accelerates the corrosion inside the piping, resulting in damage to the piping. Currently, the way to manage or clean the piping is to predict where the sludge inside the piping will accumulate, and to clean the inside after cleaning the piping, or to replace the old piping with the new piping . This results in not only a lot of time and labor required for cutting and welding the pipe, but also a loss in cost, resulting in a lot of loss in the productivity of the plant.

However, since there is no proper method of cleaning the pipe to replace it, the operator uses a method of cleaning the pipe directly. In particular, small-diameter piping that can not be used by humans can be cut and cleaned to such an extent that it can be cleaned by using a fixed tool to scrape the sludge. In addition, it is difficult to clean the inside of the piping because it is difficult to know how much sludge has settled in which part of the piping.

FIG. 1 is a view showing that a worker directly removes foreign matters from a pipe by using a cleaning tool according to the prior art.

The end of the pipe which does not flow gas during the factory repairing period is opened and the foreign substance 2, which is various kinds of sludge accumulated in the pipe 1, is scraped off with a tool.

The foreign matter 2 is scratched by looking at the inside of the pipe 1 at the end of the piping 1 that has been directly cut by the operator using the tool 20 formed so as to scrape the foreign matter 2. [

However, if the length of the pipe 1 is long, the tool 20 is required to be long, so that the inside of the pipe 1 is cleaned. There is a limit.

In addition, there is a disadvantage in that the part far from the opening does not come into view and the tool 20 can not reach and the foreign matter 2 can not be reliably scratched because the force of the person is not reached.

2 is a view showing a piping foreign matter removing robot according to the prior art.

In addition to the configuration of the robot, a vacuum generating dust collector 15 capable of sucking foreign matter 2, which is a sludge, outside the piping 1 is required. Such a vacuum generating dust collector 15 is provided with a dust- A strong suction force is required. In order to generate a strong vacuum suction force, it is inevitable that the size and the capacity of the vacuum generating dust collector 15 must be increased. Accordingly, when the piping foreign matter removing robot 10 is manufactured by a mobile type, a lot of additional equipment is required, which causes a lot of difficulties.

In addition, the foreign substance 2 inside the pipe 1 contains tar and various components, which are carbon components. Since the components are different in density, viscosity, and the like from plant to plant, the vacuum generating dust collector 15 is used to remove There is a limit.
