Description

Strainer cleaning device and cleaning method

The present invention relates to a cleaning apparatus and a cleaning method of a strainer, and more particularly, to remove the foreign matter adhering to the outer peripheral surface of the strainer opening by the gas pressure generated during explosion of the explosive line made of explosives to restore the strainer's porosity to its original state. And a cleaning device and a cleaning method of the strainer to move the removed foreign matter away from the strainer.

Recently, the problem of water shortage is emerging as a global problem, not just a specific country, and Korea is gradually emerging as a challenge as well.

Until now, most of the water needed for domestic homes and industrial facilities has been collected and supplied for drift water, and the method of supplying this drift water is by dam construction, rivers or appeals. The method of attracting and supplying water is widely used.

However, the method of supplying the drift water by dam construction suffers from difficult problems such as securing the dam's candidate site, environmental problem, and the long time required to supply water, so the development and distribution of alternative sources is urgently needed. The situation is getting worse.

In addition, the rapid economic development, the transition to high industrial society, and the improvement of people's living standards have increased the amount of toxic pollutants discharged into the rivers, and the water quality of the rivers is gradually deteriorating with time. In addition, the concentration of population and the creation of indiscriminate industrial complexes are increasing the water pollution of rivers and lakes, which are the foundation of water supply.

For the above reasons, the new water supply system does not directly take river water into raw water, but removes contaminants through proper pretreatment, and then demands an indirect intake method to supply this water to homes and industrial facilities through various water purification processes. And research and development are taking place.

As an example of the indirect intake method, the riverside filtration method is attracting attention, and the riverside filtration method is a method of installing intake wells in the alluvial aquifers widely distributed in rivers, instead of directly inflowing river waters having a very deteriorated water quality. The strainer is provided with a plurality of fine openings to filter foreign matter. Through this strainer, water passing through the alluvial aquifer is pumped.

In other words, the contaminated river water is filtered and adsorbed while passing through the alluvial aquifer and undergoes biodegradation, and the water that forms the alluvial aquifer is filtered by the strainer to improve the water quality.

In this riverside filtration method, the river water is retained in the alluvial aquifer of the stream for a long time, and the contaminants and toxins are removed after the soil is removed by using the self-cleaning action of the soil, thereby reducing the processing burden in the subsequent water purification process. This is economical and safe compared to the method of direct intake and advanced water treatment, and has the advantage of being able to respond to accidental water quality accidents.

However, according to the above-mentioned river filtration method, the water passing through the alluvial aquifer passes through the opening of the strainer. At this time, when the speed of the water flowing into the strainer increases, the history and foreign matter forming the alluvial aquifer move together with the water to move the strainer. It will block the openings. If the work continues to collect the riverside filtrate in this state, more and more of the power and debris to block the opening of the strainer, thereby reducing the strainer's permeability significantly.

In order to solve this problem, a conventional method for cleaning the strainer is a physical method of cleaning the inside of the strainer using a physical tool such as a brush or a blade, or a chemical is injected into the strainer to regenerate the strainer by dissolving foreign substances. Chemical methods were used.

However, the physical method of using the brush can clean the inside of the strainer, but there is a problem that foreign substances attached to the outside of the strainer cannot be removed. Even if foreign matter adhering to the outside of the strainer is removed, the removed foreign matter remains in the vicinity of the strainer, and as a result, when the intake process of the riverside filtration is performed again after the regeneration of the strainer is completed, There is a problem that the foreign matter stuck to the strainer again.

In addition, the physical method of removing the foreign matter of the strainer by rotating the blade by installing the blade inside the strainer is difficult to use the rotational energy of the blade in the strainer of the water well with low flow rate in the flow of the fluid, and the method of the strainer Foreign matter attached to the outside has a problem that can not be removed.

In addition, the chemical method using chemicals can remove foreign substances adhering to the outside of the strainer, but the extent of removing the foreign substances is extremely limited, and the effect is insignificant, and the problem of environmental pollution that water quality is contaminated by chemicals occurs. There is a problem.

An object of the present invention for solving the problems according to the prior art, by applying a high pressure generated by the explosive force of the bomber to the water present in the interior of the strainer to let the water out of the strainer at a high flow rate at a time, The present invention provides a cleaning apparatus and a cleaning method of a strainer capable of restoring the permeability of the strainer to its original state by removing foreign substances adhering to the inside and the outside of the opening of the strainer.

Each of the elastic contact means is characterized in that it is provided.

On the other hand, it is provided on one side of the pair of circular plate, characterized in that it further comprises an elastic contact means for elastically protruding to support the inner surface side of the strainer.

In this case, the elastic contact means, the support block, the support body accommodated in the support block so as to be protruding toward the inner surface side of the strainer, and provides a force so that the support elastically protrudes toward the inner surface side of the strainer. It is characterized by including an elastic body.

In addition, the support is characterized in that the steel ball or rod member provided with a roller at the end.

On the other hand, the dopant is characterized in that the linear material is fixed to the plurality of round rods are installed.

In addition, the cleaning method of the strainer of the present invention for solving the above technical problem, in the cleaning method of the strainer is provided in the water inlet of the river and provided with openings for filtering foreign matter, preparing a dopant line equipped with a primer, Connecting a wire to the primer; Inserting and installing the dopant line along a center of the strainer containing water; And exploding the primer at the same time by inputting an explosion signal to the respective wires to explode the dopant line so that the water is ejected through the opening of the strainer, and cleaning the strainer.

As described above, the present invention can remove foreign substances adhering to the inner and outer surfaces of the opening of the strainer by using the gas pressure generated by exploding the dopant made of explosives.

In addition, by using a detonation line that does not generate toxic gas due to a complete explosion, it is possible to remove almost no environmental pollution, and to remove foreign substances attached to the outside as well as the inside of the strainer, and the removed foreign substances are moved away from the strainer. have.

In addition, since the inside of the strainer can be moved freely, when the foreign matter attached to the entire range of the strainer is to be removed, the utility has a high advantage.

In addition, since both ends are blocked with a metal plate, when cleaning a portion of the strainer, there is an advantage that only a portion of the portion can be cleaned.

In addition, when the foreign matter attached to a specific part of the strainer is not removed well, adjusting the thickness of the width of the wire may increase the pressure of water ejection, so that the pressure applied to the foreign material increases, so that the foreign matter which is not easily removed is easy. There is an advantage that can be eliminated.

In addition, since the coupling ring is divided into four members, it can be quickly assembled and used at the time of use, there is an advantage that it is easy to store and convenient to use.
