The present invention is a solid-liquid separation device for removing solids in the waste water, comprising a suction chamber with a filtering net installed on the top and an inlet chamber sealing the upper portion of the suction chamber and a scraper that is in close contact with the surface of the filtering network to reciprocate. As the suction force is applied to the suction chamber, the waste water passes through the filtering net, and the solids are removed and the solids attached to the surface of the filtering net are removed by the scraper, so that the backwashing process is not necessary, and the effective separation and rapid removal of the fine solids is achieved. It is to enable the solid-liquid separation.

Solid-liquid separation of wastewater refers to the separation of wastewater from sewage by treatment by sedimentation or filtration of solids in the wastewater.

Solid-liquid separation through double filtration can remove relatively fine solids quickly, so it is widely used in the post-treatment process of general sewage treatment equipment or solid-liquid separation process such as food industry wastewater and livestock wastewater, and fixed filter Various types of solid-liquid separators have been developed and used, such as a centrifugal filter that induces forced discharge by rotating a cylindrical water tank equipped with a filter on an outer circumferential surface from a simple form to allow wastewater to be treated.

Such a conventional liquid-liquid separation device commonly requires a backwashing step of washing contaminants accumulated in a filter used for a long time by artificially generating a flow opposite to the flow direction of a normal treated water, and during the backwashing process, Target wastewater should be temporarily shut off or bypassed with a separate solid-liquid separator.

Therefore, not only the treatment efficiency is lowered, but also a serious problem such as having to provide a preliminary solid-liquid separator to be used in the backwashing process.

The present invention has been made in view of the above-described problems, and a flat filter net is installed on the upper part of the suction chamber connected to the suction pipe, and the inlet pipe is connected to the upper and lower suction chamber is installed so as to be lowered in close contact with the upper suction chamber It consists of a scraper that is in close contact with the surface of the inlet chamber and the filter net, and the suction force is applied to the suction pipe by an external suction force applying means such as a vacuum pump to force the wastewater in the inlet chamber to pass through the filter net and the solids attached to the filter net. By being removed by the reciprocating scraper, it is possible to maintain the performance of the filter network without a separate backwashing process, and to overcome the resistance of the filter network by forced suction to enable rapid treatment.

The detailed configuration and operation principle of the present invention will be described with reference to the accompanying drawings.

First, FIG. 1 illustrates an embodiment of the present invention, in which a suction method of a suction chamber 200 is fixed, a lifting method of an inflow chamber 100, and a scraper 300 are driven. The manner and the like are exemplified.

In the illustrated embodiment, the suction chamber 200 is fixed to the support frame 900, and rollers 310 are installed at both ends of the scraper 300 driven by the reciprocating cylinder 320, so that the outside of the suction chamber 200 is provided. The guide frame 910 is configured to move along the upper surface.

2 illustrates a state in which the inflow chamber 100 is lowered in the embodiment shown in FIG. 1, and the inflow chamber 100 is elevated by the lifting cylinder 130 installed in the support frame 900.

3 shows a state in which the scraper 300 of the present invention is operated, the scraper 300 in close contact with the surface of the filter network 210 by the reciprocating cylinder 320 is moved forward and backward, and the scraper 300 is advanced. Accordingly, the solids separated from the surface of the filtering network 210 are discharged to the outside through the slide 920 installed at the distal end of the filtering network 210.

4 is an exploded perspective view showing in detail the suction chamber 200 of the present invention, as can be seen through the drawing, the suction chamber 200 is configured in the form of a rectangular box and a plurality of through holes 201 on the upper surface ) Is formed and is connected to the suction pipe 220 at the bottom, and the filter net 210 is installed in close contact with the upper surface on which the through hole 201 is formed.

As shown in FIG. 4, the filter net 210 may be screwed through the fixing plate 211, but the installation means of the filter net 210 may be selected by a person skilled in the art. It is possible that the details of the claims are not limited thereto.

On the other hand, although not shown in the suction pipe 220 is connected to the suction force applying means, such as a vacuum pump to apply the suction force in the suction chamber 200, accordingly, the waste water in the upper portion of the suction chamber 200 is forced to filter network 210 Will pass through.

Figure 5 shows the inlet chamber 100 of the present invention, the inlet chamber 100 is configured in the form of a rectangular box in which the inlet pipe 120 is connected to the top and the bottom is open, the bottom of the circle of the figure As in the enlarged part, a packing 101 is installed to maintain closeness and airtightness to the suction chamber 200 when descending.

6 is a step-by-step illustration of the wastewater treatment process of the present invention. First, the scraper 300 is completely retracted and the inlet chamber 100 is completely lowered to close the inlet pipe 120 while being in close contact with the suction chamber 200. The wastewater to be treated is introduced into the inlet chamber 100 through the inlet chamber 100, and a suction force is applied to the suction chamber 200 to allow the wastewater to pass through the filter network 210, and then the inlet chamber 100 is fully raised and the scraper 300 is advanced. While removing the solids remaining on the top of the filter network (210).

FIG. 7 shows a crude filter network 219 installed between the filter network 210 and the suction chamber 200. As shown in FIG. 8, the crude filter network 219 is formed by filtering the filter network 210 on the upper portion of the through-hole 201. By supporting, it is to prevent the deformed deformation caused by long-term use of the fine filter (210).

When depression deformation occurs in the filter network 210, the solids attached to the depression cannot be completely removed by the scraper 300, thereby lowering the filtration efficiency, so that the filter network is too fine compared to the diameter of the through hole 201. When using (210), it is preferable to install the coarse filtration network 219 together.
