IPC: E04F17/10
Filed: 1988-08-11
Abstract: PURPOSE:To enable garbage together with miscellaneous wastes to be disposed of by providing a refuse transport means to which garbage is inputted while making use of both of water flow and air flow flowing in a main pipe wherein connection is made to a feed main pipe via branch pipes. CONSTITUTION:Miscellaneous wastes fall down within a dust chute 3 so as to be temporarily stored in a hopper 5 after they have been crashed by a crasher 4. Then, the miscellaneous wastes flow in a feed main pipe 20 through a feed branch pipe 6a together with air flow from an air inlet port 8. Following which, they flow in a miscellaneous waste separator 10 so as to be separated from air so that the miscellaneous wastes are packed in a container 12. On the other hand, refuse wherein water, air and garbage are mixed flows in a garbage separator 35 through the feed main pipe 20. In the garbage separator 35, garbage containing water is separated from air so that air is exhausted from an air exhaust port 18 through a switch-over valve 40. Garbage containing water falls down through an exhaust valve 36 so that water is separated from garbage by a water separator 37. Garbage is thereby packed in a container by a compactor 11.
