In describing the specific embodiments below, various specific details have been set forth in order to provide a more concise and clear understanding of the design. It should also be noted that the parts which are commonly known in the description of the design but are not significantly related to the design are not described in order to avoid confusion in describing the design.

Hereinafter, an inclination plate settling apparatus having a suspended matter blocking baffle according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9 attached hereto.

The inclination plate settling apparatus 1 of the present invention includes a swash plate settling tank 10 in which a ramellar swash plate 14 is embedded, a partition wall portion 20, an exhaust wear 30 and a suspended matter blocking baffle 40.

The slope plate settling tank 10 is provided with a rammel swash plate 12 and has an inlet 12 through which raw water flows into the rear side and a process water outlet 16 through which the treated water is discharged from the upper side. The raw water flowing into the slope plate settling tank 10 through the inlet 12 flows from the lower part to the upper part of the lamellar swash plate 12 and is subjected to solid-liquid separation by gravity, and the treated water passes through the treated water outlet 16 Respectively.

At this time, a partition wall portion 20, an exhaust wad 30, and a suspended solids blocking baffle 40 are formed in an upper portion of the swash plate settling tank 10 to form a flow path for discharging process water.

The partition wall portion 20 is formed in the shape of a square plate and has a U-shaped groove 22 on its upper end. The partition wall 20 is installed to connect the upper and both side walls of the slope plate settling tank 10 to form a first treated water discharge space c1. The first treated water discharge space (c1) is configured to communicate with the treated water discharge port (16). At this time, the process water flows into the first treated water discharge space (c1) through the overflow groove (22).

The discharge wipes 30 protrude forward of the partition 20 and are formed in the form of a box with an open top. The waste water 30 is formed so as to be connected to the louver groove 22 so that the treated water in the inner space c2 of the drainage wear 30 flows through the louver groove 22 and flows into the first treated water discharge space c2.

Specifically, the discharge wearer 30 includes a bottom plate 31, a side plate 32, and a front plate 35. As shown in Fig.

The bottom plate 31 is formed in a plate shape and extends horizontally forward of the partition wall 20 and is formed at a lower position than the lower end of the louver groove 22. [

The side plate 32 is composed of a pair of plates, extends vertically from both sides of the bottom plate 31, extends forwardly of the partition 20, and has a sawtooth top shape. The height of the upper end of the side plate 32 is higher than the lower end of the louver groove 22 and lower than the upper end of the partition 31. The upper end of the side plate 32 is formed by serrations 33 of zigzag.

The front plate 35 is formed in a plate shape and is formed to connect the front end of the bottom plate 31 and the front end of the side plate 32.

The floating material blocking baffle 40 is formed to protrude forward of the partition wall 20 and is formed to surround the discharge wear 30 in a state spaced apart from the outer side of the discharge wear 30. [ The suspended solids blocking baffle 40 of the present invention is configured such that the upper end is higher than the upper end of the discharge weder 30 and the lower end is lower than the upper end of the exit wear 30.

Specifically, the floating material blocking baffle 40 is configured to include both side walls 42 and a front bulkhead 45.

The both side walls 42 are formed in a plate shape and extend perpendicularly to the front of the side wall 32 and spaced apart from the side plate 32 by a predetermined distance. The lower end of the side partition wall 42 is lower than the upper end of the side plate 32. [

The front barrier ribs 45 are formed in a plate shape so as to connect the front ends of the side barrier ribs 42.

This prevents floating matters (s) such as scum and fine contaminants present on the water surface (w) in the swash plate settling tank (10) from being discharged through the discharge wipes (30).

The lower end 42a of the side wall 42 may be inclined at a predetermined angle to the discharge wearer 30 as compared with the upper end. The distance k between the lower end of the side partition wall 42 and the lower end of the side plate 32 is narrowed so that the gap between the lower end of the side partition wall 42 and the lower end of the side plate 32, It is possible to further reduce the possibility that suspended matters such as contaminants are discharged to the discharge ware 30 through the space c3 between the side partition walls 42 and the side plates 32. [

As described above, the present invention is a structure in which the floating material blocking baffle 40 is installed outside the discharge wiper 30, and the floating material s such as scum, So that only the clean supernatant below the water surface w can be discharged and the quality of the treated water can be improved.

10 and 11, in the suspended material blocking baffle 40 of the present invention, the material of the lower end portion 42a of the side partition walls 42 is made of a shape memory alloy, and the lower end portion 42a is cooled (50) that heats or heats the liquid. At this time, the temperature regulating means 50 may be constituted by an electric heater, a cooler, or the like.

The lower end portion 42a of the both side partition walls 42 is maintained at a predetermined angle inclined toward the side plate 32 of the discharge wiper 30 with respect to the upper end of the side partition walls 42 as shown in Fig. And when the temperature is equal to or higher than the predetermined temperature, the lower end portion 42a of the side partition 42 may be deformed such that the angle formed by the lower end portion 42a with respect to the upper end portion changes as shown in FIG.

At this time, the lower end portion 42a of the both side partition walls 42 may be deformed to form a straight line with respect to the upper end portion as shown in FIG. 11, or may be configured such that the angle of the lower end portion 42a is changed between angles shown in FIGS. And the lower end portion 42a of the side wall 42 may be angularly deformed so as to be inclined in a direction away from the side plate 32 at the upper end portion.

As a result, the angle of the lower end portion 42a of the side partition walls 42 of the floating material blocking baffle 40 is adjusted so that the distance k between the lower end of the side partition walls 42 and the lower end of the side plate 32 The discharge flow rate of the process water flowing into the space c3 between the side partition walls 42 and the side plate 32 and flowing over the discharge ware 30 can be adjusted.

However, if the distance between the lower end portion 42a of the side partition 42 and the side plate 32 is narrowed, the discharge flow rate is reduced and the processing speed is reduced. However, the possibility of discharge of the suspended material s is further reduced, When the distance between the lower end portion 42a of the side wall 42 and the side plate 32 is increased, the discharge flow rate is increased and the processing speed is improved. However, the discharge efficiency of the suspended material (s) Can be increased finely, and therefore can be appropriately changed at the time of designing.

In the above description, the lower end portion 42a of the side wall 42 is formed of a shape memory alloy and the lower end portion 42a is heated or cooled to adjust the angle to adjust the discharge flow rate. However, the present invention is not limited thereto, The lower end portion 42a of the partition wall 42 is hingably provided with respect to the upper end portion so that the lower end portion 42a can be angularly adjusted with respect to the upper end portion by the other driving means.

While the present invention has been shown and described with respect to a preferred embodiment for illustrating the principles of the invention, it is to be understood that the invention is not limited to the precise arrangements and acts as illustrated and described. Those skilled in the art will appreciate that many modifications and variations of the present invention may be made without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate modifications and changes, and equivalents thereof, should be regarded as within the scope of the appended claims.
