DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the accompanying drawings.

 7 to 16, the present invention relates to a vacuum device integrated with a wastewater treatment device capable of discharging wastewater generated in a toilet in a toilet to a purification tank (STP).

One side of the first drain pipe M1 is connected to the wastewater generating source and the other side is connected to the second drain pipe M2 through the first drain valve V1. The second water pipe M2 extends into the first vacuum container 01 and is coupled thereto.

An overflow prevention unit VA1 having a function of preventing negative pressure leakage of the first vacuum vessel 01 and preventing sewage overflow from the first vacuum vessel 01 is provided on the upper side of the first vacuum vessel 01, And a third solenoid valve E3 is provided in the middle of the vacuum pump suction line VA2 for the purpose of removing moisture of oil in the vacuum pump VP1. The vacuum pump VP1 provided in the vacuum pump suction line VA2 is interlocked with the second pressure switch PS2 provided in the upper portion of the first vacuum container so that gas (air, water vapor, Manure gas, etc.) and discharges it to the drain tank units 14 and 15 through the vacuum pump discharge line VA3. As a result, the vacuum container units (01, 02) and the water pipe units (M1, M2) maintain a proper sound pressure state (0.4 bar to -0.6 bar).

At this time, the third solenoid valve E3 automatically opens / closes the vacuum pump suction line VA2 according to the signal of the second pressure switch PS2, and the pressure of the first vacuum container 01 returns to normal, The vacuum pump VP1 is operated for a predetermined period of time (idling) even when the three-solenoid valve E3 is closed and the moisture in the oil in the vacuum pump VP1 is removed by the internal heat of the vacuum pump VP1 generated thereby.

An upper valve 03 is provided at an end of the second water pipe M2 extending into the first vacuum container 01. The upper valve 03 is installed to be opened and closed while the rubber plate 103 is rotated, Is closed or opened according to the pressure of the units (M1, M2) and the vacuum container units (01, 02). The vacuum container units 01 and 02 and the water pipe units M1 and M2 are maintained in a negative pressure state by the operation of the vacuum pump VP1 interlocked with the second pressure switch PS2, The rubber plate 103 of the upper valve 03 assembled at an angle of 45 degrees to the end of the second drain pipe M2 is slightly exposed at the valve seat 105 Away. The rubber plate 203 of the lower valve 04 provided in the middle of the second vacuum container 02 is pressurized by the pressure difference between the negative pressure of the second vacuum container 02 and the atmospheric pressure of the first aeration tank B1, (Not shown).

The wastewater flowing through the sewage pipe units M1 and M2 collects in the first vacuum container 01 as shown in FIG. 7 via the upper valve 03, and the large foreign substances contained in the waste water The flow is interrupted by the rack guide 16 in which the round bars 601 are assembled in two rows in the first vacuum container 01 and gradually deposited on the lower portion of the first vacuum container 01 and the first screen 07 Only the wastewater from which residual foreign matter has been removed is flowed to the second vacuum container 02 by way of passage. The wastewater from which the foreign substance is removed flows from the first vacuum container 01 to the second vacuum container 02 and eventually the wastewater level of the first vacuum container 01 and the wastewater level of the second vacuum container 02 Respectively.

At this time, when the first vacuum valve 01 is blocked by the rack guide 16 and the first screen 07, the first drain valve stopper unit The first drain valve 05 is opened after the stopper 504 of the first vacuum container 11 is removed and the foreign substance accumulated in the first vacuum container 01 is sent to the first drain tank 14.

The first vacuum container 01 is provided with first and second level switches H1 and H2 for sensing a wastewater level and a first solenoid valve E1 for operating in conjunction with the first level switch H1. When the amount of the wastewater flowing into the vacuum container units 01 and 02 reaches the position of the first level switch H1, the operation of the vacuum pump VP1 is stopped by the signal, and the first level switch H1 The first solenoid valve E1 that operates in cooperation with each other is opened to allow air to flow into the vacuum container units 01 and 02 so that the vacuum container units 01 and 02 are at atmospheric pressure. At this time, due to the pressure difference between the sewage pipe units M1 and M2 and the vacuum container units 01 and 02, the upper valve 03 is closed so that the inflow of the wastewater is blocked and the lower valve 04, (01, 02) are discharged to the first aeration tank (B1) of the septic tank. The wastewater discharged to the first aeration tank B1 is appropriately decomposed and reacted with the microorganisms through the second aeration tank B2 and is appropriately separated and disinfected in the separation tank S1 and the disinfection tank C1, And is discharged to the outside by the discharge pump DP1.

The lower valve 04 is combined with the lower valve stopper unit 10 which is provided at the middle portion of the second vacuum container 02 and restricts the operation of the lower valve 04. When the vacuum valve unit is in the atmospheric pressure state when the lower valve stopper unit 10 combined with the lower valve 04 is in the release state, the lower valve 04 is moved to the self weight of the wastewater of the vacuum container units 01 and 02 It opens naturally by. This is the case where the wastewater from the vacuum container units 01 and 02 is normally discharged to the first aeration tank B1 of the purification tank. Meanwhile, it is preferable that the lower valve stopper unit 10 is assembled on a separate plate for maintenance and fastened to the upper portion of the first aeration tank B1 by an appropriate method.

The first solenoid valve E1 is closed and the vacuum pump VP1 is operated and the vacuum container units 01 and 02 ) Is again at normal sound pressure (0.4 bar to -0.6 bar). Thereby, the lower valve 04 is completely closed and the closed upper valve 03 is opened when the negative pressure of the vacuum container unit 01, 02 becomes equal to the sound pressure of the sewage pipe units M1, M2. When the upper valve 03 is opened, the wastewater from the sewage pipe units M1 and M2 collects in the vacuum container units 01 and 02 again in the manner described above.

On the other hand, the vacuum pressure of the sewage pipe units M1 and M2 when the upper valve 03 is closed is maintained at about 0.4 bar to about -0.6 bar. At this time, when the upper valve 03 is not completely closed by the foreign substance, the vacuum pressure of the water pipe units M1 and M2 will be similar to the pressure of the vacuum container units 01 and 02 that are at atmospheric pressure. In such a case, the wastewater from the vacuum container units 01 and 02 is discharged to the first aeration tank B1 by the electric signal of the first pressure switch PS1 provided in the second water pipe M2. The process is immediately stopped and the vacuum pump VP1 is run immediately.

If the first level switch H1 malfunctions and the wastewater flowing into the vacuum container units 01 and 02 goes beyond the position of the first level switch H1 and reaches the position of the second level switch H2 The second level switch H2 is operated to stop the operation of the vacuum pump VP1 and generate an alarm.

If the wastewater continues to flow above the position of the second level switch (H2) due to a malfunction of both the first level switch (H1) and the second level switch (H2), the overflow prevention unit (VA1) (VP1).

The second vacuum valve 02 is connected to the second solenoid valve E2 and connected to the second solenoid valve E2 by a negative pressure of the second vacuum valve 02, Thereby preventing the wastewater slurry from accumulating in the lower end portion of the second vacuum container 02. [0064] As shown in FIG. It is preferable that the other side of the second solenoid valve E2 except for one side to which the second solenoid valve E2 is connected is exposed to atmosphere or a place having a pressure higher than atmospheric pressure.

Air is supplied to the air supply conduit 13 through the second solenoid valve E2 by using the negative pressure of the second vacuum container 02 to prevent the wastewater slurry from accumulating in the lower end portion of the second vacuum container 02 The second drain valve 06 provided at the lower end of the second vacuum vessel 02 is periodically opened to completely prevent the slurry accumulation from flowing into the second drain tank 15). At this time, the stopper 504 of the second drain valve stopper unit 12, which restricts the operation of the second drain valve 06, must be removed for opening the second drain valve 06.

On the other hand, in order to prevent the wastewater slurry from accumulating in the lower portion of the first drain valve 05 and the second vacuum container 02 opened to remove foreign matters accumulated in the first vacuum container 01 described above, The second drain valve 06 is provided additionally to exert the best operation performance of the present invention. In order to operate the first and second drain valves 05 and 06, a stopper of the first and second drain valve stopper units 11 and 12 combined with the first and second drain valves 05 and 06 504) should be removed. 7, 10, and 15, the weight 503, the stopper 504, the set bolt 505, and the like which are part of the first and second drain valve stopper units 11 and 12 are connected to the drain tank unit 14 , 15).
