In addition, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

First, the present invention can be applied to a water treatment device such as a screen capable of treating wastewater containing various contaminated floating matters, and will be described in detail with reference to FIGS. 1 to 5 below.

1 is a side view of a screen that is easy to maintain and increases the efficiency of removing impurities according to an embodiment of the present invention, and FIG. 2 is a screen that is easy to maintain and increases the efficiency of removing impurities according to an embodiment of the present invention. 3 is a detailed view of 'A' part of FIG. 2, and FIG. 4 is a side view showing a state in which a brush is provided on a screen that is easy to maintain and increases the removal efficiency of impurities according to an embodiment of the present invention. 5 is a plan view of a screen plate for easy maintenance and increased removal efficiency of impurities according to an embodiment of the present invention.

Referring to FIGS. 1 to 5, the screen, which is easy to maintain and increases the removal efficiency of impurities according to an embodiment of the present invention, has an upper fixture 150 and a lower fixture disposed at the bottom of the upper fixture 150. 160, and a drive motor (not shown) connected to the top fixture 150 is provided to remove impurities such as various foreign substances while rotating, roller chain 110, screen plate 120, screen rake (130) and a brush (140).

The roller chain 110 rotates in one direction through a driving motor by connecting the lower end fixture 160 to the upper end fixture 150. The roller chain 110 is formed to surround the lower end fixture 160 in the upper end fixture 150 in a loop shape. The roller chain 110 may be formed in a conventional structure, and a detailed description thereof will be omitted below.

The present invention is characterized by the screen board 120, and the screen board 120 will be described in detail.

The screen plate 120 is formed in a plate shape and coupled repeatedly and continuously along the roller chain 110, and the first screen plate 121 and the second screen plate 121 are continuously and alternately coupled to form a roller chain 110 ) rotates along with the rotation, and serves to move the impurity on one side to the other side.

At this time, the overall shape of the first screen plate 121 may be formed in a thin plate shape, and a plurality of slit holes 123 are continuously formed along the rotation direction of the screen plate 121 . Further, along the circumferential direction of the first screen plate 121, the rim plate 124 is vertically protruded to form a space inward. In addition, a plurality of connection holes are formed in the first rim plate 124 .

The first screen plate 121 formed as shown in FIG. 1 is formed in an inward groove shape, roughly like “]” with respect to the position where impurities are removed, and can play a role of trapping impurities.

The second screen plate 122 may be formed in a thin plate shape as a whole, and a plurality of slit holes 123 are continuously formed along the rotation direction of the screen plate. Then, an edge plate is formed along the circumferential direction of the first screen plate 122 . By the way, the second screen plate 122 is formed as "[" opposite to the first screen plate 121.

Both the first screen plate 121 and the second screen plate 122 are formed with elongated slit holes 123 along the rotational direction of the screen plate. Since the slit hole 123 is formed along the same direction as the rotational direction of the screen plate 120, when the screen plate 120 rotates, the water flow can be smoothly compared to the conventional perforation method, increasing the removal efficiency while The load of the screen plate 120 can be reduced.

At this time, when the first screen plate 121 and the second screen plate 122 are repeatedly arranged and combined with each other, a predetermined concave space is formed in the first screen plate 121, and impurities trapped through this space After the smooth movement, there is a feature that can be induced to be smoothly separated from the other side.

The screen rake 130 is coupled to at least one of the plurality of screen plates, and more preferably, may be coupled to the rim plate 124 formed on the first screen plate 121 . The screen rake 130 is formed in a thin plate shape and one end is detachably coupled to the edge plate 124 of the screen plate 121.

That is, the screen rake 130 is formed in an elongated strip shape corresponding to one side of the rim plate 124, and a bolt hole 132 is formed at a position corresponding to the bolt hole formed in the rim plate 124. Therefore, when replacement of the screen rake 130 is required, by simply detaching and attaching from the rim plate 124 through the coupling bolt 133, the coupling and disassembly structure of the screen rake and the screen plate can be more easily induced, leading to maintenance is easy

Since the conventional rake has a complicated structure as shown in FIG. 7, and the rake is independently coupled to the screen plate, and the rake provided independently of each other is simultaneously coupled by the fixing plate, it is difficult to separate them individually. In order to replace the rakes, there was an inconvenience of having to separate all the screen rakes at the same time. Therefore, difficulties in assembling and disassembling were followed, making overall maintenance difficult.

However, since the screen rake 130 of the present invention can be replaced through a simple detachable coupling structure without the need for a separate fixing plate for fixing the screen rake to the screen plate 120, overall maintainability can be increased It has a characteristic.

In particular, the screen rake 130 has the other end fixed to the rim plate 124 protrudes in the shape of a sawtooth 131 in the vertical direction, so that impurities can be removed smoothly compared to the conventional fine-necked screen, thereby preventing vortex formation. It can provide effective impurity removal. The shape of the teeth 131 may be formed such that the width narrows in the extending direction from one end. At this time, the teeth 131 may have a plurality of grooves repeatedly formed on both sides of the teeth 131 protruding forward. Through this groove, impurities of various shapes can be effectively removed, and in particular, impurities of a thin and long type can be induced to be filtered out.

The brush 140 may be disposed behind the top fixture 150 to collect impurities. The brush 140 may be formed in a radial direction along the circumferential direction. Therefore, the brush 140 comes into contact with the screen plate 120 and the screen rake 130 when they rotate, and separates the impurities collected through the screen plate 120 and the screen rake 130 while rotating together while separating the slit hole ( 123) can be washed. At this time, the brush 140 is provided with a driving motor (not shown) capable of rotationally driving the brush 140, so that impurities can be removed more effectively while rotating in the opposite direction to the rotational direction of the screen plate 120.

In the present invention, the brush 140 may be implemented by stacking up and down. At this time, the size of the hair of the brush 141 on the upper side is formed relatively larger than the size of the hair of the brush 142 on the lower side, so that large impurities are removed as a whole from the upper side, and the relatively large impurities are removed from the lower side. By removing small fine impurities, the overall efficiency of removing impurities can be increased.

In addition, the screen 10, which is easy to maintain and improves the removal efficiency of impurities according to the present invention, can be configured to tilt as a whole. At this time, a flow meter (not shown) may be provided on the front of the screen plate, and the tilting angle of the screen 10 may be adjusted according to the flow rate flowing into the screen. For example, when the flow rate flowing in through the flow meter is detected as higher than a predetermined rate, the removal of impurities can be more effectively induced by tilting the screen plate backward in the inflow direction at a predetermined angle.

The screen, which is easy to maintain and increases the removal efficiency of contaminants according to the present invention, can smooth the flow of water by improving the shape of perforations formed in the screen plate, is formed in a sawtooth shape, and protrudes in the vertical direction. The formation of vortices can be prevented by combining the screen rake with the screen plate to effectively remove impurities.

In addition, maintenance can be facilitated by more easily inducing a coupling and disassembly structure between the screen rake and the screen plate.

In addition to this, it is possible to increase the efficiency of the screen by preventing a load that may occur on the screen by removing impurities attached to the screen rake through the brush.
