PURPOSE: To drive a crushing mechanism part by utilizing the vacuum of vacuum sewerage piping by constituting a disposer from the crushing mechanism part driven by vacuum force and a vacuum valve cutting off a charging port and a discharge port. CONSTITUTION: A garbage charging port 3 and the discharge port 17 connected to vacuum sewerage piping 7 are provided in this disposer 15. A crushing mechanism part 16 driven by vacuum force and a vacuum valve 20 are arranged between the charging port 3 and the discharge port 17. When the vacuum valve 20 is operated to be opened, the vacuum pressure in the vacuum sewerage piping 7 acts on the charging port 3 and charged garbage is sucked under vacuum pressure to be fed through a spiral passage 18. For example, a fixed blade is provided in the spiral passage 18 and the garbage is crushed while passing through the passage 18. The crushed garbage is sucked from the discharge port 17 into the vacuum sewerage piping 7 to be fed to a sewage treatment plant. Therefore, energy such as electricity is unnecessary and wiring construction is also unnecessary and the generation of drive noise is eliminated and the maintenance and control of a drive part becomes unnecessary. |
