1 is a configuration diagram showing the arrangement of the recesses in the front of the mechanism according to the present invention, Figure 2 is a configuration diagram showing an external arrangement of the right side of FIG.

The present invention relates to a device for mounting a plate-shaped screen 30 on a filtration tank 20 connected to a reservoir 10 and a communication path 15 and continuously performing a filtration function. The reservoir 10 is provided with an inlet 11 at which the contaminated water is introduced. The filtration tank 20 has an outlet of 21 for discharging fresh water that has passed through the screen 30 and an outlet of 31 for discharging contaminants not passed through the screen 30. The contaminated water of the filtration tank 20 overflows the upper communication path 15 to reach the screen 30.

In this case, according to the present invention, a washing tube 40 having a plurality of nozzles 40a for spraying the washing water evenly is mounted at a constant interval to the upper side of the screen 30. Typically, the screen 30 is formed into a curved surface and inclined, and the cleaning pipe 40 is also disposed on the same inclined surface at regular intervals. The plurality of nozzles 40a all face the screen 30 and allow the respective injection zones to overlap slightly. The inner diameter of each of the cleaning pipes 40 must be sufficiently larger than the sum of the cross-sectional area of the flow paths of the nozzles 40a installed therein to maintain the injection force and the injection flow rate.

The washing tube 40 is open at one end and closed at the other end, so that washing water or fresh water is supplied to the open end. In FIG. 3 to be described later, an example of a pipe to the cleaning pipe 40 can be seen.

FIG. 3 is a configuration diagram showing an internal arrangement state on the right side of FIG. 1.

The branch pipe 42 to which the washing water or the fresh water is supplied is connected to one end of the washing pipe 40 through the hose 44. The branch pipe 42 can select an appropriate number of branch structures as a means for reducing the construction cost by simplifying the pipe. The branch pipe 42 is connected to the wash water tank or the fresh water outlet 21 at the outside, and is preferably equipped with a valve for controlling the flow.

At this time, one end of the cleaning tube 40 further includes an air cylinder 48 connected via a link 46 to expand the spraying range on the screen 30 by vertically rotating the nozzle 40a. To this end, the washing tube 40 should be rotatably installed, and the link 46 is connected to each washing tube 40 from the outside. The air cylinder 48 sucks and discharges air by an external signal or a manual operation of an operator to rotate the link 46 and the washing tube 40.

Accordingly, as the cleaning pipe 40 is interlocked, the spray angle of the nozzle 40a is changed up and down to wash a wide range on the screen 30. If you choose to rotate the cleaning pipe 40, the sealing means must be added to prevent leakage.

On the other hand, instead of the air cylinder 48, it is also possible to use an electric drive means such as a solenoid, a motor.

In addition, according to the present invention is provided with a flow rate adjusting means 50 is mounted on the communication path 15 so as to move up and down to vary the cross-sectional area of the flow path of the fluid flowing to the screen (30). Flow control means 50 is a structure that changes the cross-sectional area of the flow path using the adjustment screw 56 exposed to the top to allow the contaminated water to fall uniformly to the screen 30 when passing through the communication path (15).

4 is a configuration diagram partially showing an enlarged flow control means of FIG.

The flow control means 50 is composed of a support 52, a flat plate 54, a holder 58, an adjustment screw 56, etc., which are mounted using the communication path 15 and the cover 51. The cover 51 is mounted on the upper portion of the communication path 15, and the female screw portion 15a is formed. The support 52 is provided on the communication path 15 below the cover 51 at regular intervals. The flat plate 54 is mounted on the support 52 so as to be movable up and down. When the support 52 is molded into the H-shaped cross section, the flat plate 54 is firmly supported, and the vertical movement is possible. The holder 58 fixed to the flat plate 54 is shaped into a V-shaped cross section. The adjustment screw 56 is mounted to engage with the female screw portion 15a of the cover 51 and has a handle at a portion exposed to the upper portion of the cover 51. The lower end of the adjustment screw 56 is shaped into a U-shape and is rotatably received in the holder 58. When the combination of the adjusting screw 56 and the holder 58 is selected, the rotation of the adjusting screw 56 is not constrained by the flat plate 54.

Accordingly, when the adjusting screw 56 is turned, the flat screw 54 connected to the lower side of the cover 51 is lifted and lowered while being spirally moved with the female screw part 15a of the cover 51. Lifting the cover 51 as necessary separates the flat plate 54 and the adjustment screw 56 at the same time.

According to the type and amount of contaminated water supplied to the filtration tank 20 from the reservoir 10, the overflow state of the communication path 15 is uneven and the phenomenon of flowing down the screen 30 is biased. However, in the case of using the flow rate control means 50 of the present invention, it is possible to prevent the flow unbiased by properly changing the flow path cross-sectional area.

On the other hand, it is also possible to use only the flat plate 54 without using the adjusting screw 56 as a simpler configuration than the flow control means 50. In this case, it is necessary to form a long hole up and down in the contact area between the flat plate 54 and the support 52 and tighten it with a bolt, and the operator needs to unscrew the bolt, adjust the height of the flat plate 54, and then lock the bolt again. Do.

According to the above configuration and operation, the present invention has an effect of improving the performance of the system by frequently discharging the foreign matter accumulated on the screen in the process of filtering foreign matter contained in a large amount of the working fluid using the fluid treatment system of various industrial facilities.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the utility model registration claims of the present invention.
