2 is a side cross-sectional view illustrating a state in which the transport outlet of the automatic separation and drainage apparatus provided with the backflow prevention unit according to the present invention is opened.

For reference, in the detailed description of the present invention, only the backflow prevention part and the peripheral structures to be combined with the backflow prevention part will be described in detail, and a detailed description of the other structures of the automatic separation and drainage device will be given in the above- (Korean Patent Registration No. 10-0964178).

The automatic separation and drainage apparatus having the backflow prevention part according to the present invention is characterized in that the backflow prevention part fixing table 160, the backflow prevention part 180, and the backflow prevention part guide part 190 are provided in the automatic separation / .

The supporting frame 140 is fixed to the inside of the body 110 of the automatic separation and drainage apparatus having the backflow prevention unit according to the present invention, And a drain guide pipe 320 rotatably coupled to the rotary shaft 380 and rotating about the rotary shaft 380.

The center of the backflow prevention part fixing base 160 is rotatably fixed to a rotation axis 380 provided at the end of the support frame 140 by a predetermined angle, As shown in FIG.

The other end of the backflow prevention part fixing base 160 is fixedly coupled to the backflow prevention part 180 at a lower end of the drainage guide pipe 320.

One end of the backflow prevention part fixing base 160 is fixed to the fixing bracket 161 formed at the upper end of the drainage guide pipe 320 and the other end is fixed to the backflow prevention part 160 at the lower end of the drainage guide pipe 320, (180) so that it is connected obliquely to the drain guide pipe (320).

The backflow prevention part 180 moves upward and downward to remove the fluid to be drained into the inner space 112 of the body part 110 from the transfer outlet 130 of the transfer part 130, ) Is opened and closed.

3, the backflow prevention part 180 includes a coupling shaft 181 and a backflow prevention film 182. The coupling shaft 181 is configured to prevent the backflow prevention And moves up and down according to the rotation of the backflow preventing part fixing table 160. [

The backflow prevention film 182 is coupled to the lower portion of the coupling shaft 181 and moves up and down integrally with the coupling shaft 181 to open and close the transfer outlet 131.

3 is a view showing a connection between a backflow prevention part and a backflow prevention part fixing part of the automatic separation and drainage device provided with the backflow prevention part according to the present invention.

The backflow prevention part guide part 190 is formed around the conveyance outlet port 131 of the conveyance part 130 and guides the backflow prevention film 182 for opening and closing the conveyance outlet port 131 while moving up and down. do.

In addition, the backflow prevention portion guide portion 190 supports the backflow prevention film 182 to withstand the water pressure of the backwash water.

4, the backflow prevention portion guide portion 190 is brought into contact with the backflow prevention film 182 inserted with the rubber pad 191 inward to insert the backflowable water It can be surely blocked.

That is, if the backflow prevention membrane 182 is pushed backward when the backflow prevention membrane 182 is inserted, the backflow prevention membrane 182 is pushed backward when the discharge water flows back to the delivery outlet 131, So that complete watertightness of the internal space 112 of the body 110 can be maintained by contacting the rubber pad 191.

The flow of the fluid to be drained into the inlet 120 of the body 110 is blocked by the pressure of the fluid flowing into the internal space 112 of the body 110, The contact with the rubber pad 191 is released and the watertight state of the internal space 112 is released.

When the watertightness of the internal space 112 is released, the fluid flowing into the internal space 112 of the body 110 is discharged through the gap between the countercurrent prevention membrane 182 and the transfer outlet 131.

4 is a view showing a structure of a backflow prevention part guide part of an automatic separation and drainage device provided with a backflow prevention part according to the present invention.

The operation of the automatic separation and drainage apparatus having the above-described construction with the check valve according to the present invention will be described.

The fluid to be drained flows into the interior of the body 110 through the inlet 120 provided at one side of the body 110 and is filled and stored from the lower surface of the internal space.

The fluid to be drained stored in the inner space continues to flow and is partially sucked into the conveying outlet 131 of the conveying unit 130 and is conveyed to the treatment process but flows out through the conveying outlet 131 The flow rate of the fluid to be drained is relatively smaller than the flow rate of the fluid to be drained into the inlet 120, so that the level of the drainage fluid stored in the inner space gradually increases.

The liquid level of the fluid to be drained stored in the inner space continues to rise and the lifting chamber 360 coupled to one end of the drainage guide tube 320 is lifted by the buoyancy force, The drain guide pipe 320 is rotated.

As the drainage guide pipe 320 rotates, the backflow prevention part 180 coupled to the other end of the drainage guide pipe 320 is lowered so that the backflow prevention film 182 closes the transfer outlet 131 as shown in FIG. 5 .

At the same time, the fluid to be drained flows into the inlet 120, flows into the inside of the drain guide pipe 320 through the one end, and is discharged into the chamber 210 through the other end.

Meanwhile, when the inflow of the fluid to be drained stops, the fluid to be drained stored in the inner space flows out between the gap between the backflow prevention film 182 and the transfer outlet 131, so that the water level is gradually lowered, The buoyant force acting on the chamber 360 weakens and the drain guide pipe 320 rotates about the rotation axis 380 to maintain the initial state before the drainage fluid is introduced as shown in FIG. .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
