Definitions

  • the present invention relates to the technical field of domestic waste transportation, and in particular to a method and system for transferring and loading domestic waste.
  • the main purpose of compressing domestic waste is to remove the water in it. If the sewage in the domestic waste is not squeezed out, it will penetrate into the soil and groundwater after landfill, causing soil and groundwater pollution, which will seriously harm the ecological environment.
  • domestic waste incineration power generation has gradually replaced landfill as the main method of domestic waste treatment, the traditional method of compressing domestic waste before transporting it to large domestic waste dumps has not changed.
  • the compression mechanism is easily damaged. Domestic waste can easily cause jamming, corrosion and other damage to the moving parts of the compression mechanism.
  • the composition of domestic waste is complex, and there may be stones, tiles and even steel bars in domestic waste. These hard objects can also easily jam and damage the compression mechanism.
  • Compression processing prolongs the domestic waste treatment process.
  • the compression process itself will increase the cost of domestic waste treatment and seriously reduce the efficiency of transferring domestic waste from transfer stations to incineration sites.
  • the "hook-arm” garbage transport that matches the compression treatment method has more "dead weight” and less effective load.
  • the hook-arm type of the hook-arm type transport vehicle is a laborious lever.
  • the chassis vehicle needs to increase the "dead weight” of the hook arm.
  • the garbage bin that matches the hook-arm type transport vehicle has to increase the strength of the box body, which increases the "dead weight” of the garbage bin.
  • the "dead weight” added in multiple places has greatly reduced the effective load of the transport.
  • the suction port of the negative pressure suction device is arranged on the outside of the lower end of the funnel or on the outside of the upper end of the funnel, but the suction is performed on the outside of the funnel. Since the odor rushes out of the funnel at a high speed under the impact of garbage, and the outside of the funnel, especially the outside of the upper end of the funnel, is a large open space, the negative pressure suction port is at a long distance from the gas odor source. Therefore, it is difficult to absorb the odor escaping from the funnel if the suction port is arranged on the outside of the funnel mouth. Therefore, the suction effect of the odor is poor, and a large amount of odor leakage will cause serious air pollution, which is also the main reason for the air pollution around the existing garbage transfer station.
