In general, a sand layer is accommodated as a filter medium for filtration in a filtration tank used in a water treatment facility such as a water purification plant or a simple water supply facility. A surface cleaning device is installed and used.

That is, a conventional surface washing device is installed on the upper part of a filtration tank used in a water treatment facility such as a water purification plant or a simple water supply facility, and is used for washing the sand layer by spraying washing water on the sand layer in the filtration tank.

There was a problem in that economical overburden occurred such as frequent filter media replacement due to backwashing.

In other words, the conventional surface washing apparatus cannot spray the washing water over the entire surface of the sand layer due to the occurrence of blind spots, and thus there is a problem of lowering the filtration efficiency.

Furthermore, since the conventional surface washing apparatus is cleaned by simply spraying the washing water, there is a problem in that the washing water is not smoothly guided to the surface of the sand layer and at the same time washing and filtration efficiency is lowered.

Therefore, it is possible to spray the washing water over the entire surface of the sand layer, which is the filter material, without blind spots, and at the same time, to maximize the washing efficiency and filtration efficiency by allowing the washing air to be sprayed together with the washing water in multiple stages toward the sand layer surface. Research and development of a surface cleaning device is required.

In other words, in a state in which the left and right washing air injection connectors 430' and 440' are disposed adjacently to the lower side of the washing water injection connector 300', for example, a pair of brackets (not shown) surrounding two separate tubes. time) and a bolt (not shown) for fixing the pair of brackets, it may be fixed to the washing water jet connector 300 ′ and the left or right washing air jet connector 430 ′, 440 ′.

According to the mixed rotary unit type surface washing apparatus according to the present invention having the configuration as described above, in the through hole of the lower connection housing through which the vertical part of the rotary type unit as a rotary structure, the entire washing water society and the whole washing water society is installed through the hole. The entire cleaning air spraying society having a rotation shaft that is arranged and fixed by welding so as to be rotatably rotatably integrated with the vertical portion is applied while surrounding the outer surface of the vertical portion, so that the cleaning air is sprayed adjacent to the injection of the cleaning water together with the cleaning water, while cleaning the cleaning area of the filter paper. By maximizing it, the washing water and washing air can be sprayed over the entire surface of the sand layer, which is the filter material, without dead spots, while maximizing the washing efficiency of the filter yarn's surface area, and at the same time, washing air with washing water is doubled toward the surface of the sand layer and the wall of the filter tank. It is possible to maximize the filtration efficiency by improving the cleaning efficiency and the removal efficiency of fine sludge and oil layer during backwashing.

Furthermore, the entire washing water spraying society having a rotational shaft that is rotatably welded and fixed integrally with the vertical part is disposed in the through hole of the lower connection housing through which the vertical part of the washing water spraying society is installed and surrounds the outer surface of the vertical part. It is possible to increase the jetting power of washing water by spraying washing air adjacent to the

In addition, by connecting the lower connection housing to the lower side of the rotary housing of the rotary type unit in a flange joint structure, disassembly and assembly are easy, and installation and maintenance can be made easily.

In addition, the entire vertical part of the washing water jet society is disposed in the through hole of the lower connection housing through which it is installed, and the entire washing air jet society having a rotation shaft that is fixed by welding to be rotatably rotatable integrally with the vertical part while enclosing the outer surface of the vertical part is applied. By manufacturing as a rotary unit type as a structure, the structure can be simplified to a single-stage structure, unlike in a two- or more-stage rotary unit type structure, and through this, assembly and installation are simple and cost reduction can be realized at the same time.

Although specific embodiments of the present invention have been described in detail above, the present invention is not limited thereto, and various modifications can be made by those skilled in the art to which the present invention pertains. are included within the scope of the present invention.
