DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The present invention will now be illustrated by the following examples. The present invention is a sewage suction and pressure transfer device and a sewage treatment device equipped with a sewage suction and pressure transfer device for general buildings, with a structure without shutters, based on Patent Application No. 2022-129252, "Sewage suction and pressure transfer device and sewage treatment device equipped with a sewage suction and pressure transfer device," which was previously filed by the applicant for use on railways. For general buildings, the sewage treatment equipment equipped with a sewage suction and pressure transfer device is connected directly to the sewer pipe.

[0021] Patent application No. 2022-129252, "Sewage suction and pressure transfer device and sewage treatment device equipped with the sewage suction and pressure transfer device," "A wastewater treatment device consisting of a wastewater pipe 12 equipped with a wastewater suction and pressure transfer device main body 1, which is installed in the middle of the wastewater pipe 12 connecting the downstream side of the opening and closing device installed at the waste outlet of a fresh water pneumatic western-style toilet 4 of a vehicle, etc., and the waste inlet of a wastewater tank 13, and which is characterized by sucking and pressure transfer the waste, water and paper in the fresh water pneumatic western-style toilet 4 with the suction and pushing forces generated when compressed air is sprayed at high speed from a narrow gap, and pouring them into the wastewater tank 13." It consists of: Railway toilet systems are mechanical toilet systems that use compressed air for each operation. For example, the flushing water is also done by using air pressure to create a strong water pressure. In addition, flappers, slide valves, etc. are also operated using air pressure. Therefore, a large amount of air is used, and depending on the system, a large amount of air is consumed, equivalent to 10 to 25 liters at atmospheric pressure.

[0022] 1 to 8 are diagrams showing the configuration of a sewage pipe 21 equipped with a sewage suction and pressure-feeding device and a sewage treatment device according to the present invention, and show the air flow in the sewage pipe 21 equipped with the sewage suction and pressure-feeding device and the sewage treatment device. A is the air flow. A1 is the air flow to the inlet of the waste suction and pumping device. A2 is the compressed air flow supplied to the waste suction and pumping device. A3 is the air flow amplified by the waste suction and pumping device.

[0023] In the figure, 1 is the main body of the waste suction and pressure transfer device. 4 is a freshwater Western-style toilet. 41 is a bowl in the freshwater Western-style toilet 4. 2 is a solenoid valve for the waste suction and pressure transfer device. 3 is a compressed air pipe. Reference numeral 21 denotes a wastewater pipe, and 13 denotes a sewer pipe. In this embodiment of the invention, the waste suction and pumping device body 1 is attached to a freshwater Western-style toilet 4 for general buildings. Toilets for general buildings do not have a waste tank, so they are directly connected to the sewer pipe 13.

[0024] The sewage pipe 21 is an S-shaped pipe. 22 is a rotating shaft provided midway through the sewage pipe 21. The sewage pipe 21, which is an S-shaped pipe, can be rotated 140 degrees around the rotating shaft 22 from the state shown in FIG. 4 to the state shown in FIG. 6 in order to save space. The waste suction and pumping device body 1 is installed midway along the wastewater pipe 21 connecting the freshwater toilet 4 and the sewer pipe 13. Reference numerals 10 and 11 denote toilet flush water pipes. The toilet flush water pipe 10 and the toilet flush water pipe 11 supply flush water to the freshwater toilet 4.

[0025] Reference numeral 23 denotes a trap. The trap 23 is provided in the wastewater pipe 21 with an S-shaped trap structure as shown in the drawing. Under normal circumstances, the trap 23 is sealed with water by collecting water, similar to a general toilet. The trap 23 is sealed with water by collecting water up to the line l shown in FIG. 1. The trap 23 is an S-shaped trap, an S-shaped water seal device (used in household sinks and toilets). By adopting the S-shaped trap of the embodiment of this invention without using mechanical devices such as shutter valves and flappers as in Patent Application No. 2022-129252, it can be used for general construction (buildings, apartments, etc.).

[0026] When a flush button (not shown) is pressed, the sewage suction and pumping device main body 1, which is a sewage suction device, is driven to suck up the water and sewage in the trap 23 and bowl 41. The sewage is sucked up from the end of the pipe. At the same time, cleaning water is discharged, and even after suction has finished, the cleaning water continues to be discharged. When water has accumulated in the trap 23, the cleaning is completed. The action of the sewage suction and pumping device 1 draws in the surrounding air into the water flow and increases the flow rate. By passing air through the sewage pipe 21, which is a special type of pipe consisting of an S-shaped pipe, the air is sucked into the piping side, and the accumulated water moves to the piping side, the sewer 13 side, and when the water seal is broken, air begins to flow.

[0027] The installation position of the waste suction and pressure transfer device main unit 1 is as close as possible to the waste outlet of the freshwater toilet 4, the toilet discharge port. Theoretically, the further away from the toilet outlet, the lower the suction force (negative pressure). The minimum range is several tens of centimeters. The maximum range is one meter. The direction of the compressed air discharge is toward the outlet (sewer pipe 13 side), and by creating an air flow, a suction pressure (negative pressure) is generated on the opposite side of the compressed air discharge (toilet outlet). This negative pressure is used to vacuum-suck up waste from inside the toilet.

[0028] A certain amount of compressed air is supplied to the sewage suction / pumping device main body 1 from a separately installed air compressor B via a sewage suction / pumping device solenoid valve 2 and compressed air piping 3. The air compressor B is an extremely small compressed air generator, with a volume of 5 liters when converted to atmospheric pressure. When compressed air is supplied, the suction force generated by the air flow A of the compressed air generates an air flow A downward from the top of the fresh water toilet 4, and an air flow A toward the inlet of the waste suction and pressure transfer device. This air flow A3 is amplified in the waste suction and pressure transfer device main body 1, and becomes a force that pushes the waste into the sewer pipe 13, allowing the odor to be discharged along with the waste, sewage, and paper.

[0029] In this invention, the sewage pipe 21 is equipped with a sewage suction and pressure transfer device main body 1, which is installed in the middle of the sewage pipe 21 connecting the downstream side of the opening and closing device provided at the sewage outlet of the freshwater toilet 4 and the sewage inlet of the sewer pipe 13, and is characterized in that the suction force and pushing force generated when compressed air is sprayed at high speed from a narrow gap are used to suck up and pressure transfer the sewage, water, and paper in the freshwater toilet 4 and flush them into the sewer pipe 13. Therefore, the main body of the sewage suction and pressure transfer device 1 is installed midway in the sewage pipe 21 which connects the downstream side of the opening and closing device provided at the sewage outlet of the freshwater toilet 4 to the sewage inlet of the sewer pipe 13, and the sewage, sewage and paper in the freshwater toilet 4 are sucked up and pressure transferred by the suction and pushing forces generated when compressed air is sprayed at high speed from a narrow gap, and flowed into the sewer pipe 13, eliminating the need to make the sewage pipe 21 steeper and relaxing the constraints on the installation of the sewage pipe 21.

[0030] Therefore, this invention uses a sewage pipe 21 equipped with a sewage suction and pressure transfer device main body 1 which is installed in the middle of the pipe connecting the downstream side of the opening and closing device provided at the sewage outlet of the freshwater toilet 4 and the sewage inlet of the sewer pipe 13, and which uses the suction and pushing forces generated when compressed air is sprayed at high speed from a narrow gap to suck up and pressure transfer the sewage, water and paper inside the toilet and pour them into the sewer pipe 13, thereby easing the restrictions on the size and gradient of the sewage pipe 21 from the freshwater toilet 4 to the sewer pipe 13.

[0031] In this invention, the sewage suction / pumping device main body 1 is a sewage pipe 21 equipped with the sewage suction / pumping device main body 1 that utilizes compressed air supplied from an air compressor B that is separately provided. Therefore, in this invention, by supplying the compressed air used in the sewage suction and pumping device main body 1 from an air compressor B, it is possible to easily replace an existing sewage pipe 21 with a sewage pipe 21 equipped with the sewage suction and pumping device main body 1.

[0032] This invention further provides a sewage pipe 21 equipped with the sewage suction and pressure transfer device main body 1, characterized in that the supply and stop of compressed air to the sewage suction and pressure transfer device main body 1 is linked to an opening and closing device provided at the sewage outlet of the freshwater toilet 4.In this sewage pipe 21 equipped with the sewage suction and pressure transfer device main body 1, the supply and stop of compressed air to the sewage suction and pressure transfer device main body 1 is linked to the opening and closing of the opening and closing device provided at the sewage outlet of the freshwater toilet 4, so that when the opening and closing device at the sewage outlet of the freshwater toilet 4 is operated, an air flow is created from the freshwater toilet 4 in the direction of the sewer pipe 13, thereby reducing or preventing odors from rising from the sewer pipe 13.

[0033] The present invention may further comprise a sewage suction / pumping device main body 1 in which compressed air is supplied to the sewage suction / pumping device main body 1 after the pressure in the sewer pipe 13 and the sewage pipe 21 has been released in advance. In this case, in the sewage pipe 21 equipped with the sewage suction and pumping device main body 1, the pressure in the sewer pipe 13 and the sewage pipe 21 is released in advance, and then compressed air is supplied to the sewage suction and pumping device main body 1, thereby preventing the phenomenon of sewage being blown up into the freshwater toilet 4.

[0034] Therefore, by first releasing the pressure in the sewer pipe 13 and the sewage pipe 21 and then supplying compressed air to the sewage suction and pressure-feeding device body 1, it is possible to prevent the sewage from being blown up.

[0035] If the diameter of the sewage pipe 21 is narrowed, the suction power increases, but this also means that the number of breakdowns increases. If the diameter of the sewage pipe 21 is widened, the opposite phenomenon occurs. Considering the relationship between pipe diameter and suction power, a small diameter and a location close to the toilet are preferable. Increasing the compressed air pressure increases the suction force (negative pressure), but there is a limit to how much it can be used.

[0036] On the other hand, in the embodiment of the present invention, a component that only discharges compressed air is attached to the sewage pipe 21, so negative pressure is generated on the toilet bowl side by the air flow in the sewage pipe 21. This air flow only sucks in the sewage waste and toilet paper in the toilet bowl, so no foreign matter can get into the dedicated pressure-feed component.

[0037] The pressure-feed toilet of this invention is equipped with a single part at the toilet outlet that simultaneously performs suction and pressure (vacuum pressurization). By performing suction and pressure simultaneously in the wastewater pipe 21 with a single part, waste and wastewater do not move out of the wastewater pipe 21, overcoming the drawbacks of the vacuum type. A large amount of water is required just for the force of the water flow, but in the embodiment of the present invention, the water flow entrains the surrounding air and the flow speed increases, so the amount of water required can be reduced to about 10 to 20%.

[0038] When the flush button is pressed, the sewage suction and pumping device main body 1, which is a sewage suction device, is driven to suck up the water and sewage in the trap 23 and bowl 41. At the same time, flush water is discharged from toilet flush water pipe 10 and toilet flush water pipe 11, and continues to be discharged even after suction has finished. When water has accumulated in trap 23, flushing ends.

[0039] Conventionally, 5 liters is considered the standard water-saving type for building use, but in the embodiment of this invention, the amount of flushing water can be reduced to about 300 cc. Railway toilet systems are mechanical toilet systems that use compressed air for each operation. For example, the flushing water is also done by using air pressure to create a strong water pressure. In addition, flappers, slide valves, etc. are also operated using air pressure. Therefore, railway toilet systems use a large amount of air, consuming a large amount of air, ranging from 10 liters to 25 liters at atmospheric pressure depending on the system.

[0040] In the embodiment of the present invention, air pressure is used for the first time in general construction, so compressed air is required, and a very small compressed air generator is required. The railroad version requires a large amount of air because it is a pneumatic device from the start, but the general building version is only used in the area where wastewater is drained, so a small amount of air is sufficient. Air compressor B has a supply volume of 5 liters at atmospheric pressure. [Explanation of symbols]
