This will be described in detail.

First, in the present invention, a vacuum container 10 containing wastewater, an inlet 12 and an outlet 14 provided at upper and lower portions of the vacuum container 10, and first and

second valves

20 and 20. '), The vacuum pump 30 for generating a negative pressure in the vacuum vessel, the solenoid valve 36 for releasing the negative pressure in the vacuum vessel, and the water level sensing for sensing the water level. A sensor 34 is provided, as well as the above components, as well as a controller 40 for controlling the overall operation of the device.

The vacuum vessel 10 is a sealed cylinder, the bottom is a cone-shaped and the top and bottom are assembled with a flange to facilitate maintenance and maintenance. And the sewage pipe (2) which is connected to the toilet (1, 1 ') is connected to the outside of the inlet (12) provided in the vertical direction in the upper portion of the vacuum vessel and the first valve 20 is provided at the inner end of the vacuum vessel, The second valve 20 ′ is provided at the outlet 14 provided in the vertical direction in the lower cone portion.

The first valve 20 is a negative pressure (-) in the vacuum vessel, that is, lightly shut off the inlet in the vacuum state, and conversely completely at atmospheric pressure, and the second valve 20 'is the pressure in the vacuum vessel In the negative pressure (ie) vacuum state, the outlet port is completely blocked and conversely, in the atmospheric pressure state, it is lightly closed by the restoring force of the elastic body.

According to the present invention, the first and second valves 20 and 20 'are hinged 24 by the first and second valve discs 22 and 22' for opening and closing the upper inlet 12 or the outlet 14. ) Is assembled to the hinge 24, the elastic member 26 is provided with an elastic restoring force. In other words, the first and second valve discs 22 and 22 'are assembled on the hinge 24 at one side of the valve seat formed at the front end of the first and second valves 20 and 20'. It is opened, and the contact surface is provided with a leakage preventing member including a gasket 28 as a means for preventing leakage. As shown in the drawing, the inlet 12 and the outlet 14 are installed in the vertical direction and the first and second valve discs 22 and 22 'come into contact with the valve seat obliquely formed at the bottom. At this time, the elastic restoring force of the elastic body 26 is added while the first and second valve discs 22 and 22 'are opened, and the restoring force acts to return to the original position and contact the valve seat.

Next, as the vacuum pump 30 forcibly discharges the air through the upper exhaust port 32 of the vacuum vessel, the pressure inside the vacuum vessel drops, generates a negative pressure (−), and maintains the vacuum state. At this time, the pressure sensor 38 attached to the controller detects the pressure inside the container, and the vacuum pump operates under the control of the controller to maintain the internal pressure of the vacuum container within a predetermined range.

The solenoid valve 36 is the solenoid valve that is opened and closed while electrically operating in accordance with the control signal of the controller by increasing the outside air into the vacuum vessel to the atmospheric pressure state.

The veterinary detection sensor 34 detects a certain amount when the level in the vacuum vessel, that is, the water level increases, and signals the controller to discharge the sewage contained in the vacuum vessel.

The controller 40 controls the device according to the signals detected by the components, and includes a speaker (not shown) that emits an alarm sound when a malfunction or failure occurs and a warning light indicating a danger.

Next, according to another embodiment of the present invention, the inlet 12 and the outlet 14 of the present invention is characterized in that the lower side is opened to the side bent 'L'. That is, by forming

banding portions

12a and 14a at the lower end of the inlet 12 or the outlet 14 and opening the side to the outlet side toward the inner side of the vacuum container, the sewage is generated while falling vertically. The impact force, the noise and the like are prevented and the first and second valve discs 22 and 22 'are smoothly operated. The bending

portions

12a and 14a are bent in a 'L' shape and preferably constituted by an elbow for piping.

In the meantime, the first and second valves 20 and 20 'may exclude or selectively configure an elastic body 26 for returning the first and second valve discs 22 and 22'. And can be changed in the production process.

Looking at the operating state of the automatic discharge device of the vacuum toilet system configured as described above, first, the vacuum vessel 10 is a negative pressure (-) is applied to the inside by the vacuum pump 30 and the pressure sensor detects it and maintains a constant Let's do it. At this time, the second valve 20 ′ completely blocks the outlet 14 due to the difference between the external atmospheric pressure and the negative pressure, and the first valve 20 lightly blocks the inlet by the restoring force of the elastic body. Sound pressure also acts on the sewage pipe 2 connected to the toilet bowl. Then, when the toilet is used, the sewage in the toilet and the sewer pipe is sucked through the inlet opening the first valve.

Then, when the level of sewage in the vacuum container 10 rises, the water level is sensed by the water level sensor 34, and as the solenoid valve 36 operates, the inside of the vacuum container rises and the sewage Is discharged downward by opening the second valve (20 ') of the discharge port by its own weight and the inside of the container is emptied. At this time, the sewage pipe (2) and the inlet 12 has a negative pressure (-) is maintained in a state in which the first valve is closed.

After that, when the inside of the vacuum container is in the atmospheric pressure state, the pressure sensor 38 detects this, and after a predetermined time (2 to 30 seconds) has elapsed, the solenoid valve is shut off and the vacuum pump 30 is operated so that the vacuum container is again in a vacuum state. Is maintained.

The present invention is to automatically discharge the sewage by varying the vacuum pressure in the vacuum container, there is little risk of occurrence of breakage or failure of the discharge pump, etc., the configuration is simple, the manufacturing cost and manufacturing cost is low, economical and industrial availability This is a very high technology.
