Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piping cleaning apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pipe cleaning apparatus, and more particularly, to a pipe cleaning apparatus for effectively removing various foreign substances deposited inside a water supply piping inside and outside a building.

Generally, when a water pipe is used for a long time, various solid matters and foreign matter are accumulated therein, and the inner surface of the pipe is oxidized to generate rust and the quality of the water supplied through the pipe is lowered.

This is not hygienic and can not meet drinking standards. In the case of heating pipes, the thermal conductivity is lowered and energy consumption is caused. Therefore, the inside of the pipe is cleaned by various devices and methods to remove these scales.

Conventionally, as shown in FIG. 9, there is a method of cleaning the inside of the pipe by scraping the inside of the pipe by feeding the cleaning pig 10 into the inside of the pipe by feeding a tool called the cleaning pig 10.

However, in the piping installation structure of the related art as described above, in order to clean the inside of the pipe using the cleaning pig 10, it is necessary to cut the pipe, insert the cleaning pig 10 and then connect it again, Therefore, there is a problem that the cleaning work inside the pipe is extremely difficult.

In addition, the cleaning method of the piping cleaning by the cleaning pig (10) uses a pig (10) having a diameter larger than the diameter of the pipe (20) regardless of whether water pressure or pump pressure is used, There is a problem that the cleaning piggy 10 is unable to advance because the resistance of the cleaning pig 10 is large and the work is often interrupted. A solution to the problem by increasing the feeding pressure of the pump is to break the weakened pipe This is also not a desirable solution.

Therefore, a method of cleaning a pipe, in which sand particles are used to hit the inner wall surface of the pipe by using sand (sand) instead of using the cleaning pig 10 as described above to reduce the scale, and a method of cleaning a pipe, as disclosed in Japanese Patent Laid-Open No. 5-057261 A pipe cleaning method for cleaning the inner surface of the pipe by spraying compressed air and water from the nozzle to the inner surface of the pipe is proposed. However, in the above scale removal method by the sand, since the main component of the sand is silica sand, The use of high-pressure water causes the sand to become entangled with each other, and when high-pressure compressed air is used, the uncontrolled high-pressure air injection does not improve the cleaning performance of the pipe.

Even the high-pressure compressed air may cause the piping to deteriorate in a weakened state, and this method also has a disadvantage that its use is limited.

FIG. 2 is a schematic structural view showing a pipe cleaning apparatus according to an embodiment of the present invention. FIG. 3 is a schematic structural view showing a pipe cleaning apparatus according to another embodiment of the present invention. FIG. 7 is a schematic configuration diagram showing a piping cleaning apparatus according to another embodiment. FIG.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The pipe cleaning apparatus according to the embodiment of the present invention includes an air compression wave generator 110 for generating intermittently high pressure air at a predetermined interval, An air supply pipe 120 having an anti-check valve 121 and an air supply pipe 120 connected to the air supply pipe 120. One end of the air supply pipe 120 is connected to the outdoor pipe A by an outdoor pipe connection 131, A water supply pipe 130 connected to the indoor pipe C is connected to the indoor pipe connection port 131 and a bubble backflow check valve 122 is provided between the water backflow prevention check valve 121 and the outdoor pipe connection pipe 131 .

At this time, the piping between the bubble backflow prevention check valve 122 and the indoor pipe connection port 132 in the water supply pipe 130 is referred to as a bubble mixture supply pipe 140.

Therefore, the bubble backflow prevention check valve 122 allows the flow of the bubbles generated from the air compression wave generator 110 to flow only in one direction, that is, toward the bubble mixture supply pipe 140, thereby improving the cleaning efficiency inside the pipe by the high- Function.

The air compressor wave generator 110 includes a compressor 111 having an air tank for generating and accumulating high-pressure air, a pressure gauge 112 for measuring the pressure of the air tank, A solenoid valve 113 for intermittently discharging the high-pressure air of the pressure gauge 112 in accordance with the set time, a controller for adjusting the pressure of the pressure gauge 112 to a set pressure, and adjusting a closing time of the solenoid valve 113 114).

At this time, the pressure of the pressure gauge is preferably set to 5 to 7 kgf / cm 2 , and the optimum pressure is 6 kgf / cm 2 . At this time, when the pressure is lower than 5 kgf / cm 2, the air pressure is insufficient and the cleaning is not easy. When the pressure is less than 7 kgf / cm 2 If the pressure is higher than the pressure, it is difficult because the air pressure is too high and there is a risk of damage or breakage of the pipe. In this way, the controller 114 is automatically set to maintain the pressure of the pressure gauge at 5 to 7 kgf / cm 2 at all times.

The coke valve 133 may be installed in the water supply pipe between the bubble backflow check valve 122 and the outdoor pipe connection pipe 131 in case the raw water is excessively introduced into the water pipe, So that the water pressure can be adjusted by adjusting the cock valve 133. If the water pressure is too high, the high-pressure air waves are pushed out at a high speed by the hydrostatic pressure, and therefore, the high-pressure air waves are discharged before the water is cleaned. This is one of the serious causes of lowering cleaning efficiency.

In addition, when the water pressure flowing into the water supply pipe between the bubble backflow check valve 122 and the outdoor pipe connection pipe 131 is too low, the opposite problem arises. In other words, sufficient water pressure does not act inside the pipe This is because the cleaning efficiency is lowered.

Therefore, in this case, it is preferable to increase the water pressure by attaching the pump 140 to the water supply pipe between the check valve preventive check valve and the outdoor pipe connection pipe.

As described above, according to the present invention, an optimal piping cleaning effect can be obtained by delicately controlling the pressure of air generated in the water pressure and air compression wave generator 110.

Also, the water supply pipe between the bubble backflow prevention check valve and the outdoor pipe connection pipe may be configured so that the magnetization water handler 150 is connected by the connectors 151 and 152.

This is a way of solving all the problems of the existing pipe cleaning apparatus with the numerical value obtained from experience of many years of pipe cleaning.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
