As shown in the drawings, the present invention relates to an automatic discharge device for a vacuum toilet system which is capable of discharging domestic wastewater generated in places such as a toilet in a toilet or a sink in a kitchen to a septic tank.

The sewage pipe 100 is connected to the waste water source, and one end of the sewage pipe 100 is connected to the interior of the vacuum container 200. A vacuum line L1 is connected to the upper side of the vacuum container 200 and a vacuum pump 300 is connected to the vacuum line L1 to maintain the vacuum container 200 and the drain pipe 100 at a proper sound pressure.

An upper valve 400 is provided at an end of a sewage pipe 100 extending into the vacuum container 200. The upper valve 400 is installed to be opened and closed while the upper valve disk 410 is rotated, And the upper valve 400 is closed or opened according to the pressure of the vacuum container 200.

The vacuum vessel 200 and the drainage pipe 100 are kept at a negative pressure state by the operation of the vacuum pump 300. When the vacuum vessel 200 and the drainage pipe 100 are at the same sound pressure state, The upper valve disc 410 is lightly in contact with the upper valve seat 420 and is opened by the weight of the wastewater when the wastewater flows into the water pipe 100. The wastewater flowing into the sewage pipe 100 passes through the upper valve 400 and is collected in the vacuum container 200.

When the amount of the wastewater flowing into the vacuum container 200 reaches the first upper limit line 201, when the third solenoid valve E3 is opened and air enters into the vacuum container 200 to be at atmospheric pressure, The upper valve 400 is closed due to the difference in pressure of the vacuum container 200 so that the inflow of the wastewater is blocked and the lower valve 500 to be described later is opened to discharge the wastewater from the vacuum container 200.

A first level switch R1 and a second level switch R2 are provided inside the vacuum container 200 and a third solenoid valve E3 is also provided.

The first level switch R1 and the second level switch R2 function to detect an amount of wastewater flowing into the vacuum container 200 and generate an electrical signal. The second level switch R2 functions as a first level switch And is provided at a position higher than the switch R1.

The first level switch R1 senses that the wastewater reaches the first upper limit line 201 and the second level switch R2 senses that the wastewater reaches the second upper limit line 202. [

The third solenoid valve E3 is interlocked with the first level switch R1. When the wastewater reaches the first upper limit line 201, the first level switch R1 operates to generate an electrical signal, By this signal The operation of the vacuum pump 300 is stopped and the third solenoid valve E3 is opened to allow the outside air to be supplied into the vacuum chamber 200. [ When the outside air flows into the vacuum container 200 in a negative pressure state, the vacuum is broken and the inside of the vacuum container 200 is at atmospheric pressure.

If the first level switch R1 malfunctions or malfunctions, the wastewater flows continuously over the first upper limit line 201 as occasion demands. When the wastewater reaches the second upper limit line 202, the second level switch R2 is operated to stop the operation of the vacuum pump 300 and generate an alarm. If wastewater continues to flow over the second upper limit line 202 due to a malfunction of both the first level switch R1 and the second level switch R2, the wastewater flows into the vacuum line L1 by the suction force of the vacuum pump 300 It may contaminate the vacuum line L1 and the vacuum pump 300 and cause a failure.

The present invention is basically the same as the first embodiment except that the operation of the vacuum pump 300 when the sewage pipe 100 and the vacuum container 200 are maintained at the set pressure and the wastewater is introduced and the introduced wastewater is discharged into the purification tank 700 It must be stopped. However, since the vacuum pump 300 is continuously operated at a different time, the vacuum pump 300 must be intermittently operated.

For this purpose, the internal pressure of the vacuum container 200 is checked to operate the vacuum pump 300 when the vacuum pump 200 is out of the set vacuum pressure range. A first pressure switch P1 is provided to check the internal pressure of the vacuum container 200. In this embodiment, the first pressure switch P1 is mounted on the vacuum container 200. [ When the internal pressure of the vacuum container 200 is out of the set range, the first pressure switch P1 is operated to operate the vacuum pump 300. When the internal pressure of the vacuum container 200 reaches the set range, The operation of the pump 300 is stopped.

A lower valve 500 is provided at the lower end of the vacuum container 200. The lower valve 500 is coupled to be accommodated in a box-shaped discharge container 600. The discharge container 600 is connected to a septic tank Lt; / RTI >

The first flange F1 may be disposed on the lower end of the vacuum container 200 and the first flange F1 may be provided on the upper end of the connection pipe 610 to allow the first flange F1 to be easily installed and freely installed in various environments. The second flange F2 coupled to the second flange F2 is engaged. The lower valve 500 is coupled to the lower end of the coupling pipe 610. The lower valve 500 coupled to the end of the lower end of the coupling pipe 610 is bent at an angle of about 45 degrees So as to have an oblique inclination angle.

If the lower valve 500 is not completely closed and the lower valve 500 leaks and the negative pressure of the vacuum container 200 is not formed There is a case. In order to prevent such a case, the lower valve 500 is provided with an angle of about 45 degrees so that the lower valve 500 and the lower valve seat 520 are completely discharged without leaving toilet paper or fiber.

The third flange F3 is coupled to the lower end of the discharge vessel 600 and the fourth flange F4 is provided on the upper end of the pipe 710 connected to the purifying tank 700 to form the third flange F3. And the fourth flange F4 are used to easily connect the discharge vessel 600 and the purification tank 700 together.

The piping 710 connected to the septic tank 700 can be easily changed into various forms as needed and has a merit of being simple in maintenance work by being coupled with the discharge vessel 600 by the flanges F3 and F4.

The lower valve 500 has the same configuration as that of the upper valve 400 and is opened and closed in accordance with a pressure difference between the vacuum container 200 and the discharge container 600. Specifically, the discharge vessel 600 is always in an atmospheric pressure state, and the vacuum vessel 200 may be in a vacuum state or an atmospheric state. When the vacuum container 200 is in the vacuum state and the discharge container 600 is at the atmospheric pressure, the lower valve 500 is closed by the pressure difference, and the vacuum container 200 is opened for discharging the wastewater flowing into the vacuum container 200 , The lower valve 500 is opened by the weight of the waste water.

Although the lower valve 500 is basically opened or closed due to the pressure difference between the vacuum container 200 and the discharge container 600, in the case of the present invention, in order to initially contact the lower valve disk 510 to the lower valve seat 520 A lower valve pressurizing unit 800 is provided in the discharge vessel 600.

The lower valve pressurizing unit can be implemented in two forms, and can be divided into the case of using an electromagnet and the case of using a vacuum pressure depending on the driving method of the lower valve pressurizing unit.

As shown in FIG. 5, the lower valve biasing unit in the case of using an electromagnet will be described. The biasing unit includes a biasing lever 820 in which a vertex portion is connected to the supporting base by a pin, An iron plate 860 connected to an end of the pivot lever 860 and extending to an upper portion of the discharge vessel, an iron plate 870 coupled to an upper end of the iron plate 860, and an electromagnet 880 and the like. The electromagnet 880 is fixed to the bracket 881 provided on the upper side of the discharge vessel with a bolt 882.

The turning lever 820 is in a state in which one end of the turning lever 820 presses the lower valve disk 510 of the lower valve 500 by the weight of the weight 840 attached to the other end of the turning lever 820 do. At this time, the iron plate fixing base 860 and the iron plate 870 attached to the end of the rotation lever 820 are rotated clockwise and separated from the electromagnet 880.

If the level of the waste water in the vacuum container 200 rises and the third solenoid valve E3 is opened and the outside air is supplied into the vacuum container 200 and the vacuum of the vacuum container 200 in a negative pressure state is broken, When the valve 500 is opened, the pressure of the discharged wastewater acts on the lower valve disc 510, so that the turning lever 820 is rotated counterclockwise to overcome the force of the weight 840. At this time, the iron plate fixing base 860 and the iron plate 870 attached to the end of the rotation lever 820 are also rotated in the clockwise direction to contact the electromagnet 880.

At this time, when the electromagnet 880 is excited, the iron plate 870 attached to the iron plate fixing base 860 sticks to the electromagnet 880, so that the turning lever 820 is kept rotated in the counterclockwise direction.

Thus, even if the discharge pressure of the wastewater discharged from the vacuum container 200 is discharged and the lower valve disk 510 is lowered, the rotation lever 820 can not rotate in the clockwise direction. Thus, as shown in Fig. The lower valve 500 is completely opened so that no toilet paper or fiber remains on the lower valve and the lower valve seat, and the discharge is completely completed.

The weight of the weight 840 attached to the other end of the pivotal lever 820 causes the pivotal lever 820 to naturally rotate in the clockwise direction to rotate the pivotal lever 820, So that one end of the lower valve disk 510 is in the original state of pressing the lower valve disk 510 of the lower valve 500.

Next, a case in which the operation of the lower valve pressurizing unit is performed by the vacuum pressure will be described, and reference is made to Fig. 6 or Fig.

A lower valve pressurizing unit 800 is provided adjacent to the lower valve 500 in the discharge vessel 600. The lower valve pressurizing unit 800 includes a support 810, a pivotal lever 820, an actuator 830, a weight 840, And a support base 850.

A support base 810 fixed vertically to the inner surface of the upper portion of the discharge vessel 600 and a pivotal lever 820 connected to the support base 810 by a pin are provided. Preferably, the pivoting lever 820 has a umbrella shape, and a vertex of the pivoting lever 820 is connected to the support 810. And one side of the pivoting lever 820 pivots freely between the pivoting lever supports 850.

The actuator 830 includes a piston 831. The piston 831 is connected to the other end of the pivotal lever support 850 and the piston 831 moves up and down in the vertical direction, Vertical motion.

The weight 840 is provided at the other end of the pivotal lever 820. When no external force acts on the pivotal lever 820 due to the weight of the weight 840, the pivotal lever 820 is naturally clockwise And one end of the pivoting lever 820 is pressed to press the lower valve disk 510 of the lower valve 500. [

The actuator 830 may be any that can move the piston 831 up and down. In this embodiment, the piston 831 is raised by the vacuum pressure.

In order to operate the actuator 830 by using the vacuum pressure, the auxiliary vacuum line L2 connected to the drain pipe 100 is disposed in the present embodiment, and one end of the auxiliary vacuum line L2 is connected to the actuator 830 And the fourth solenoid valve E4 is mounted on the auxiliary vacuum line L2.

Since the auxiliary vacuum line L2 is connected to the drain pipe 100, it has the same pressure as that of the drain pipe 100, so that the auxiliary vacuum line L2 maintains a negative pressure state. The lower valve 500 is closed by pivoting the pivoting lever 820 in the clockwise direction and pressing the lower valve disc 510. At this time, the actuator 830 does not operate. That is, the piston 831 is in a lowered state. A spring (not shown) is built in the actuator 830 so that the piston 831 receives a downward force by a spring force.

If the level of the waste water in the vacuum container 200 rises and the third solenoid valve E3 is opened and the outside air is supplied into the vacuum container 200 and the vacuum of the vacuum container 200 in a negative pressure state is broken, When the valve 500 is opened, the pressure of the discharged wastewater acts on the lower valve disc 510, so that the turning lever 820 is rotated counterclockwise to overcome the force of the weight 840. At this time, the fourth solenoid valve E4 is opened and a vacuum is applied to the actuator 830 so that the pivotal lever support 850 connected to the piston 831 and the piston 831 by the vacuum pressure is also raised. When the tilt lever support 850 rises, the tilt lever 820 and the tilt lever support 850 are brought into contact with the tilt lever pin 851 with the lower valve 500 opened.

The pivotal lever 820 which is in contact with the pivotal lever pin 851 is pushed by the pivotal lever support 850 even if the discharge pressure of the wastewater acting on the lower valve disk 510 is lowered as the wastewater in the vacuum container 200 is discharged. It is impossible to rotate in the clockwise direction.

Thereby, the lower valve 500 is completely opened, so that no toilet paper or fiber remains in the lower valve 500 and the lower valve seat 520, and the discharge is completely performed.

When the fourth solenoid valve E4 is closed after a certain period of time, the vacuum pressure acting on the actuator 830 is released and connected to the piston 831 and the piston 831 by a spring (not shown) incorporated in the actuator 830 The pivot lever support 850 is lowered.

The weight of the weight 840 of the tilt lever 820 causes the tilt lever 820 to naturally rotate in the clockwise direction so that one end of the tilt lever 820 is positioned below the lower valve disk 510 of the lower valve 500 It becomes the original state of pressurization.

When the lower valve disc contacts the lower valve seat due to the pushing force of the pivotal lever, the lower valve disc closes while being in close contact with the lower valve seat due to the pressure difference between the vacuum container in the negative pressure state and the discharge container in the atmospheric pressure state.

The second check valve C2 may be provided in the auxiliary vacuum line L2 and the second check valve C2 may be provided in the vicinity of the end of the auxiliary vacuum line L2 connected to the sewage pipe 100, Thereby preventing the wastewater flowing into the auxiliary vacuum line L2 from flowing into the auxiliary vacuum line L2.

The overflow prevention device 900 is provided in the vacuum line L1 that connects the vacuum container 200 and the vacuum pump 300 to prevent malfunction or malfunction of the device, The vacuum line L1 is closed to prevent the wastewater from flowing into the vacuum line L1 when the wastewater continues to flow into the vacuum vessel 200 and the wastewater reaches the third upper limit line 203, .

More specifically, the overflow prevention device 900 includes a floating pipe 910, a reducer 920, and a dumbbell fitting 930. One end of the reducer 920 is connected to the upper end of the floating pipe 910 and the other end of the reducer 910 is connected to the upper end of the floating pipe 910. The floating pipe 910 is connected to the lower end of the vacuum pipe 200, The other end of the Dyusha 920 is connected to the vacuum line L1.

As shown in FIG. 9, the reducer 920 is a component whose inner diameter is reduced. When the dumbbell shaped portion 930 is raised, the inlet is clogged.

The dumbbell shaped opening 930 is installed inside the floating tube 910 and the reducer 920 so that the first and second openings 931 and 932 are connected by the connecting rod 933. When the excess sewage flows into the vacuum container 200 and reaches the third upper limit line 203, the first inlet 931 is brought into contact with the sewage, Closing the inlet of the reducer 920 to block the vacuum line L1.

The first check valve C1 may be provided on the upper portion of the reducer 920 so that the vacuum line L1 may be provided with a vacuum check valve So that leakage of air to the container 200 can be prevented. That is, the first check valve (C1) closes the vacuum line (L1) when the vacuum pump (300) is not operating due to a proper set pressure of the vacuum container (200) ) To prevent leakage.

A first solenoid valve E1 and a second solenoid valve E2 are disposed on the suction side of each vacuum pump 300. A second pressure switch P2 and a second solenoid valve E2 are provided on the discharge side of each vacuum pump 300, 3 Place the pressure switch (P3).

The first solenoid valve E1 and the second solenoid valve E2 are used as a means for preventing the emulsification of the oil contained in the vacuum pump 300. The first solenoid valve E1 and the second solenoid valve E2 Is closed and the vacuum pump 300 idles to evaporate water contained in the oil by the high temperature and high degree of vacuum of the raised vacuum pump casing and moisture evaporated by the air introduced through the gas ballast valve of the vacuum pump And can be discharged to the outside.

The second pressure switch P2 and the third pressure switch P3 stop the vacuum pump when the discharge pressure of the vacuum pump 300 is 0.5 bar or more due to clogging of the discharge filter of the vacuum pump 300, And the like.

And a control panel 1000 for the entire automatic control of the present invention.

When the first pressure switch P1 senses the vacuum pressure of the vacuum container 200 and sends a signal to the control panel 1000, the vacuum pump 300 repeats operation and stop according to the control of the control panel 1000, (Vacuum container and sewage pipe) Vacuum pressure is kept at -0.40 to -0.55 bar.

Wastewater discharged from a wastewater generating source such as a toilet is introduced into the vacuum vessel 200 through the sewage pipe 100. The lower valve 500 is connected to the vacuum pressure of the vacuum vessel 200 and the discharge vessel 600 connected to the purification vessel 700 Lt; RTI ID = 0.0 > closed. &Lt; / RTI >

On the other hand, when the wastewater flows into the vacuum container 200 continuously beyond the first upper limit line 201 due to a failure of the first level switch R1 or the like, the second level switch R2 provided on the second upper limit line 202 So that the vacuum pump 300 is immediately stopped and an alarm is generated to notify the manager.

If the second level switch R2 fails or an immediate action is not taken and the second upper limit line 202 goes beyond the third upper limit line 203, the overflow prevention device 900 is operated Thereby preventing the inflow of wastewater into the vacuum line L1.

On the other hand, if an abnormal inflow of sewage into the vacuum container 200 occurs, the sewage may be introduced into the auxiliary vacuum line L2 connected to the sewage pipe 100. The second check valve C2 is provided in the auxiliary vacuum line L2 to prevent the wastewater from flowing into the auxiliary vacuum line L2 so that when the wastewater flows into the auxiliary vacuum line L2, (C2) can block the auxiliary vacuum line (L2).

The present invention can be used as an automatic discharge device of a vacuum toilet system.
