Description

TECHNICAL FIELD [0001] The present invention relates to a strainer cleaning device for a debris filter,

The present invention relates to a strainer cleaning device for a filter, and more particularly, to a cleaning device installed in a water inlet of a power plant for facilitating the cleaning work of a debris filter strainer for removing seawater foreign substances.

In general, when pumping seawater used as cooling water in a thermal power plant, dirt and shellfish suspended in the intake water are first removed from the coarse screen, and ultimately removed from the coarse screen, such as dirt, A debris-filter is installed between the outlet of the circulating water pump and the inlet of the condenser.

Inside the debris filter structure, a cylindrical strainer part is mounted for adsorbing foreign matter during the flow of seawater, and the strainer is removed from the filter housing during decomposition and maintenance of the filter body, And work is performed.

1, a worker manually removes foreign matter adhering to the outer wall surface by using an electric wheel grinder. The grinder wheel is used to hold the strainer 100 with one hand and the grinder wheel So that the cleaning operation for removing the foreign substances is performed, so that the cleaning operation can not be easily performed.

Especially, it requires a lot of work time because it requires to manually clean about 246 strainer by each machine, so that foreign matter, dust, etc. are blown in the work process and there is a risk of safety accident due to wheel grinder .

The present invention has been proposed in order to solve the above problems in the prior art, and it is an object of the present invention to improve a working efficiency and a safe washing operation by developing a washing device capable of performing a filter strainer washing operation more safely and effectively .

In order to achieve the above object, the cleaning device of the present invention is characterized in that an upper lid is openable and closable on an upper part of a main body of the apparatus, A cleaning brush is formed at the center of the inside of the apparatus main body; Wherein a plurality of rotating seatbelts rotatable about the periphery of the cleaning brush and to which the filter strainer can be individually seated can be rotatably provided at a lower portion of the apparatus main body; A support rod for supporting the filter strainer is formed on the upper portion of the rotary seat; A driven gear for rotating the rotary seat is formed at the bottom of each rotary seat; A drive gear for transmitting the rotational force of the drive motor to the driven gear is formed at a lower center of the apparatus main body; And an upper platen for pivoting the upper portion of the filter strainer seated on the rotary seat is rotatably mounted on the upper lid.

In the present invention, since the automatic washing operation can be performed through the electric rotary drive in a state where a large number of debris filter strainer is mounted in the apparatus, it is possible to shorten the parts cleaning work time and improve the work safety It shows the effect.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the structure of a strainer cleaning device for a debris filter according to an embodiment of the present invention will be described with reference to FIGS. 2 to 6. FIG.

An upper lid 20 is openable and closable at the upper part of the apparatus main body 10 formed in a cylindrical shape and a cleaning brush 30 is formed at the center of the inside of the apparatus main body 10, A plurality of rotary mounts 40 are rotatably mounted around the cleaning brush 30 so that the filter strainer 100 can be seated individually and the filter strainer 40 And a driven gear 50 for rotating the rotary seating table 40 is formed at the lower portion of each of the rotary seating platforms 40. The lower center of the apparatus body 10 A driving gear 60 for transmitting the rotational force of the driving motor 70 to the driven gear 50 is formed in the upper lid 20 and a driving gear 60 for transmitting the rotational force of the driving motor 70 to the upper portion of the filter strainer 100, And an upper pressure plate (80) for pressing the upper pressure plate .

The upper lid 20 is connected to a water supply pipe 21 for supplying washing water to the inside of the debris filter 100. A water supply pipe 21 is connected to the lower part of the apparatus body 10, A drain pipe 22 for drainage of water is connected.

The rotating seat 41 is provided with a lower rubber 42 for increasing frictional force with the filter strainer 100. The upper pressing plate 80 is provided with an upper portion 42 for pressing and supporting the filter strainer 100 with a predetermined elastic force, And a through hole 82 is formed in the upper rubber 81 and the upper pressure plate 80 so that the wash water supplied through the water supply pipe 21 can be guided.

At this time, the lower rubber 42 and the upper rubber 81 are preferably semicircular so that the lower and upper portions of the filter strainer 100 can be fitted.

A plurality of elastic protrusions 42a are protruded from the lower rubber 42 to increase the coupling force with the lower portion of the filter strainer 100 and to secure the discharge space for the washing water.

It is preferable that the water flow grooves 41a are formed in the shape of a screw so that the washing water supplied through the water supply pipe 21 may collide with the inner wall of the filter strainer 100.

An ultraviolet lamp 90 for sterilizing function is formed on the inner wall surface of the apparatus main body 10.

Hereinafter, the effects of the use of the devising filter for cleaning a strainer of the present invention will be described.

First, the upper lid 20 formed on the upper portion of the apparatus body 10 is opened to seat a plurality of filter strainer 100, which are removed from the debris filter structure, inside the present cleaning apparatus.

That is, at this time, if each filter strainer 100 is placed on the rotary mount table 40, the vertically standing state can be stably maintained by the support rod 41, and each filter strainer 100 can be cleaned So that the brush 30 is brought into a contact state.

When the upper lid 20 is closed with the plurality of filter strainer 100 mounted, the upper and lower portions of the filter strainer 100 are pressed by the upper rubber plate 81 and the upper rubber plate 81, respectively, And is stably held by the lower rubber 42. [

In particular, since the lower rubber 42 is provided with a plurality of elastic protrusions 42a, the support force of the filter strainer 100 against the lower end of the filter strainer 100 can be maximized.

When power is applied to the drive motor 70 in a state where the filter strainer 100 is completely mounted, the motor drive force is transmitted to the driven gear 50 through the drive gear 60, So that the filter strainer 100 is rotated at a high speed together with the rotation of the filter strainer 100, so that the outer surface of the filter strainer 100 is removed by friction with the cleaning brush 30.

The washing water supplied through the water pipe 21 is supplied into the filter strainer 100 which is rotated at a high speed through the through hole 82 so that the inner wall surface of the filter strainer 100 can be simultaneously cleaned do.

The washing water supplied into the filter strainer 100 is discharged through a plurality of filter holes 110 finely formed on the surface of the filter strainer 100 by centrifugal force inside the filter strainer 100, As shown in FIG.

In particular, since the screw-shaped water flow grooves 41a are formed along the length of the support rod 41, the cleaning efficiency can be improved by impacting the wall surface of the washing and filtering filter strainer 100 with a stronger force.

Since the ultraviolet rays are emitted by the ultraviolet lamp 90 during the course of the cleaning operation, the sterilizing action is applied to the surface of the filter strainer 100, so that the foreign matter removal efficiency by the cleaning brush 30 can be increased do.

Accordingly, when the cleaning device of the present invention is used, a large number of cleaning operations can be simultaneously performed on a plurality of filter strainer 100, and internal cleaning is performed through the supply of washing water simultaneously with the external cleaning by the cleaning brush 30 The cleaning efficiency can be improved.
