However, the drawings presented are one specific embodiment based on the technical idea of the present invention, and thus the scope of the present invention is not limited to the drawings.

Attached Figure 3 shows the overall configuration of the automatic discharge device for enhanced safety of the vacuum toilet system according to a preferred embodiment of the present invention, Figure 4 is a cross-sectional view of the main part of the present invention applying the lower valve pressurization unit using an electromagnet, Figure 5 is an enlarged view of the lower valve pressurization unit using an electromagnet, Figure 6 is a vacuum pressure actuator using an auxiliary vacuum line 7 is an enlarged view of a lower valve pressurizing unit and a vacuum actuator, and FIG. 8 is a cross-sectional view showing an open state of a lower valve, and FIG. 9 is an enlarged cross-sectional view of an overflow preventing device. 10 shows a perspective view of the main part of the present invention.

As shown in the present invention, the present invention relates to an automatic discharge device for a safety-enhanced vacuum toilet system capable of discharging living sewage generated from a toilet or a kitchen sink to a septic tank.

The sewage pipe 100 is connected to a sewage generating source, and one end of the sewage pipe 100 extends and is coupled to the inside of the vacuum container 200. The vacuum line (L1) is connected to the upper side of the vacuum vessel (200) and the vacuum pump (300) is connected to the vacuum line (L1) to maintain the vacuum vessel 200 and the sewage pipe (100) at an appropriate negative pressure.

The upper valve 400 is provided at the end of the sewage pipe 100 extending into the vacuum vessel 200, the upper valve 400 is installed so that the upper valve disk 410 can be opened and closed, the sewage pipe 100 And the upper valve 400 is closed or opened according to the pressure of the vacuum vessel 200.

Normally, the vacuum vessel 200 and the sewage pipe 100 are maintained in a negative pressure state by the operation of the vacuum pump 300, and when the vacuum vessel 200 and the sewage pipe 100 are in the same negative pressure state of the upper valve 400. The upper valve disc 410 is lightly in contact with the upper valve seat 420, when the sewage flows into the sewage pipe 100 is opened by the own weight of the sewage. Sewage flowing into the sewage pipe 100 passes through the upper valve 400 and is collected in the vacuum vessel 200.

When the amount of sewage introduced into the vacuum vessel 200 reaches the first upper limit 201, when the third solenoid valve E3 is opened and air is introduced into the vacuum vessel 200 to reach atmospheric pressure, the sewage pipe 100 and Due to the pressure difference of the vacuum vessel 200, the upper valve 400 is closed to block the inflow of sewage, and the lower valve 500 to be described later is opened to discharge the sewage from the vacuum vessel 200.

The first level switch R1 and the second level switch R2 are provided in the vacuum chamber 200, and the third solenoid valve E3 is also provided.

The first level switch R1 and the second level switch R2 detect an amount of sewage flowing into the vacuum vessel 200 to generate an electrical signal, and the second level switch R2 has a first level. It is provided at a position higher than the switch R1.

The first level switch R1 detects that the sewage is up to the first upper limit 201, and the second level switch R2 detects that the sewage is up to the second upper limit 202.

On the other hand, the third solenoid valve (E3) is interlocked with the first level switch (R1), when the sewage is filled up to the first upper limit 201, the first level switch (R1) is activated 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 so that outside air is supplied into the vacuum vessel 200. When the outside air flows into the vacuum container 200 which is in the negative pressure state, the vacuum is broken and the inside of the vacuum container 200 becomes an atmospheric pressure state.

In some cases, when the first level switch R1 fails or malfunctions, the wastewater continues to flow beyond the first upper limit 201. When the sewage reaches the second upper limit 202, the second level switch R2 is operated to stop the operation of the vacuum pump 300 and generate an alarm. If sewage continues to flow above the second upper limit 202 due to a malfunction of both the first level switch R1 and the second level switch R2, the sewage may be transferred to the vacuum line L1 by the suction force of the vacuum pump 300. Inflow will pollute the vacuum line (L1) and the vacuum pump 300, etc. will cause a failure.

Meanwhile, the present invention basically maintains the sewage pipe 100 and the vacuum container 200 in a set negative pressure state, and the sewage flows in, and when the introduced sewage is discharged to the septic tank 700, the operation of the vacuum pump 300 is performed. It must be stopped. However, the continuous operation of the vacuum pump 300 at other times is a considerable energy consumption, so the vacuum pump 300 should be operated intermittently.

To this end, the vacuum pump 300 is operated when the internal pressure of the vacuum vessel 200 is checked to move out of the set vacuum pressure range. The first pressure switch (P1) for checking the internal pressure of the vacuum vessel 200 is provided in this case, in the present embodiment, the first pressure switch (P1) is to be mounted to the vacuum vessel (200). When the internal pressure of the vacuum vessel 200 is out of the setting range, the first pressure switch P1 is operated to operate the vacuum pump 300. When the internal pressure of the vacuum vessel 200 is within the setting range, the vacuum is applied. The operation of the pump 300 is stopped.

A lower valve 500 is provided at the lower side of the vacuum container 200, and the lower valve 500 is coupled to be accommodated in the box-type discharge container 600, and the discharge container 600 is connected to a septic tank through a pipe 710. Connected with 700.

In the present embodiment, in order to facilitate installation and to be freely installed in various environments, the first flange F1 is placed at the bottom of the vacuum container 200, and the upper end of the connection pipe 610 is connected to the first flange F1. A second flange (F2) coupled to the is coupled. The lower valve 500 is coupled to the lower end of the connecting pipe 610, and preferably the lower end of the connecting pipe 610 is bent toward one side and the lower valve 500 coupled to the end thereof is about 45 degrees. Combined to have an oblique angle of inclination at an angle of.

When toilet paper or fiber is stuck in the lower valve disc 510 and the lower valve seat 520, the lower valve 500 does not close completely, so that the lower valve 500 leaks, so that the negative pressure of the vacuum container 200 is not formed. There is a case. In order to prevent such a case by giving an angle of about 45 degrees to the lower valve 500, the lower valve 500 and the lower valve seat 520, such as toilet paper or fiber is left without leaving completely discharge.

Meanwhile, 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 that is connected to the septic tank 700. Using the fourth flange (F4) and to easily connect the discharge vessel 600 and the septic tank (700).

The pipe 710 connected to the septic tank 700 can be easily changed into various shapes as necessary, and has an advantage of easy operation during maintenance by combining with the discharge vessel 600 by the flanges (F3, F4).

The lower valve 500 is configured in the same configuration as the upper valve 400, the opening and closing is made according to the pressure difference between the vacuum vessel 200 and the discharge vessel 600. Specifically, the discharge vessel 600 is always at atmospheric pressure, the vacuum vessel 200 may be a vacuum or atmospheric pressure. When the vacuum container 200 is in a vacuum state, and the discharge container 600 is in an atmospheric pressure state, the lower valve 500 is closed by a pressure difference, and the vacuum container 200 is used to discharge the sewage introduced into the vacuum container 200. When the outside air is introduced into the atmospheric pressure, the lower valve 500 is opened by the own weight of the sewage.

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

The lower valve pressurizing unit may be implemented in two forms, and may be classified into a case using an electromagnet and a case using a vacuum pressure according to a driving method of the lower valve pressurizing unit.

First, the lower valve pressurizing unit in the case of using an electromagnet will be described, and as shown in FIG. 5, the vertex portion of the shape is attached to the pivoting lever 820 connected to the support and the pin, which is attached to the other end of the pivoting lever. Weight (840), the weight is connected to the end of the combined rotation lever, the iron plate fixing rod 860 extending to the top of the discharge vessel, the iron plate 870 is coupled to the top plate plate 860 and the electromagnet to stick to the iron plate ( 880) and the like. The electromagnet 880 is fixed to the bracket (881) provided on the discharge vessel with a bolt 882.

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

If the sewage level of the vacuum vessel 200 rises, the third solenoid valve E3 opens, the outside air is supplied into the vacuum vessel 200, and the lower portion of the vacuum vessel 200 in the negative pressure state is destroyed. When the valve 500 is opened, the pressure of the discharged sewage acts on the lower valve disc 510 so that the rotation lever 820 is rotated counterclockwise to overcome the force of the weight 840. At this time, the iron plate holder 860 and the iron plate 870 attached to the end of the rotation lever 820 is also rotated clockwise to contact the electromagnet 880.

At this time, when the electromagnet 880 is excited, the iron plate 870 attached to the iron plate fixing stand 860 adheres to the electromagnet 880 to maintain the pivoting lever 820 rotated in a counterclockwise direction.

As a result, even when the wastewater of the vacuum container 200 is discharged and the discharge pressure of the wastewater acting on the lower valve disc 510 is lowered, the rotation lever 820 does not rotate clockwise. This is as shown in FIG. The lower valve 500 is completely opened, and toilet paper or fiber is not left in the lower valve and the lower valve seat, and discharge is completely made.

When the electromagnet 880 is decomposed after a certain time, the rotation lever 820 rotates naturally clockwise by the weight of the weight 840 attached to the other end of the rotation lever 820, the rotation lever 820 One end of the lower valve 500 is to be in the original state to press the lower valve disk 510.

Next, a case in which the operation of the lower valve pressurization unit is performed by vacuum pressure will be described, and refer to FIG. 6 or 7.

The lower valve pressurizing unit 800 is provided in the discharge container 600 adjacent to the lower valve 500, and includes a support 810, a rotation lever 820, an actuator 830, a weight 840, and a rotation lever. It comprises a support (850).

A support 810 is vertically fixed to the upper inner surface of the discharge vessel 600 is provided, the pivoting lever 820 is connected to the support 810 by a pin is rotatable. Preferably, the pivoting lever 820 forms a hat shade, and a vertex portion of the pivoting lever 820 is connected to the support 810. And one side of the rotation lever 820 is free to rotate between the rotation lever support (850).

Actuator 830 includes a piston 831, the piston 831 is connected to the other end of the rotation lever support 850, the piston 831 vertically up and down, accordingly, the rotation lever support 850 also up and down Vertical movement.

The weight 840 is provided at the other end of the rotation lever 820, and when no external force acts on the rotation lever 820 by the weight of the weight 840, the rotation lever 820 naturally clockwise. It is rotated so that one end of the rotation lever 820 pressurizes the lower valve disc 510 of the lower valve 500.

The actuator 830 may be any one capable of moving the piston 831 up and down. In this embodiment, the piston 831 is raised by the vacuum pressure.

In this embodiment, to operate the actuator 830 by using a vacuum pressure, the auxiliary vacuum line (L2) is connected to the sewage pipe (100), one end of the auxiliary vacuum line (L2) is connected to the actuator (830) The fourth solenoid valve E4 is mounted on the auxiliary vacuum line L2.

Since the auxiliary vacuum line (L2) is connected to the sewage pipe (100) has the same pressure as the sewage pipe (100), the auxiliary vacuum line (L2) maintains a negative pressure state. The lower valve 500 is closed by the rotation lever 820 is rotated clockwise to press the lower valve disk 510, the actuator 830 is not operated at this time. That is, the piston 831 is in the lowered state. A spring (not shown) is built in the actuator 830 so that the piston 831 is forced downward by the spring force.

If the sewage level of the vacuum vessel 200 rises, the third solenoid valve E3 opens, the outside air is supplied into the vacuum vessel 200, and the lower portion of the vacuum vessel 200 in the negative pressure state is destroyed. When the valve 500 is opened, the pressure of the discharged sewage acts on the lower valve disc 510 so that the rotation lever 820 is rotated counterclockwise to overcome the force of the weight 840. At this time, as the fourth solenoid valve E4 is opened, a vacuum acts on the actuator 830, and the pivot lever support 850 connected to the piston 831 and the piston 831 is also raised by the vacuum pressure. As such, when the pivot lever support 850 rises, the pivot lever 820 and the pivot lever support 850 come into contact with the pivot lever pin 851 in a state where the lower valve 500 is opened.

Even though the wastewater of the vacuum container 200 is discharged and the discharge pressure of the wastewater acting on the lower valve disc 510 is lowered, the rotation lever 820 contacted by the rotation lever pin 851 is the rotation lever support 850. When is raised, it cannot be turned clockwise.

As a result, the lower valve 500 is completely opened, and toilet paper or fiber is not left in the lower valve 500 and the lower valve seat 520 to be completely discharged.

When the fourth solenoid valve E4 is closed after a certain 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) built in the actuator 830. Rotating lever support 850 is lowered.

As a result, the rotation lever 820 is rotated in a clockwise direction by the weight of the weight 840 of the rotation lever 820 so that one end of the rotation lever 820 opens the lower valve disc 510 of the lower valve 500. It becomes the original state to pressurize.

When the lower valve disc is in contact with the lower valve seat by the pushing force of the rotation lever, the lower valve disc is closed by being closer to the lower valve seat by the pressure difference between the vacuum container in the negative pressure state and the discharge container in the atmospheric pressure state.
