Definitions

  • a means for dampening and disintegrating garbage including means introducing the garbage by means of a [30] Foreign Apphcanon Pmflfiy Data conveyor, such as a screw into a container, under Feb. 9, 1970 Germany ..P 20 05 7935 pressure from one end of the container, and passing steam into and through the garbage from a pipe enter- [52] 11.8. CI. ..34/227, 34/37, 100/73 i g h o h nd of he contain r. The am may be [51] Int.
  • the invention relates to a method of dampening garbage in the interior of the collecting container of a garbage loading truck, and a garbage loading truck therefor.
  • the dampening of the garbage assists in its disintegration.
  • a spray distribution system located below the ceiling of a nonrotatable garbage collection container is fed with garbage by a screw conveyor extending longitudinally over its floor.
  • the screw conveyor simultaneously has a tamping effect on the garbage in the container. This tamping action by the screw is increased by the disintegration caused by the addition of water.
  • the tamping effect of the screw is improved by the disintegration caused by the addition of water.
  • the storage container in this case must hold a considerable amount of water, because during spraying into the outer space of the hollow cone, a large amount "of water flows through the charging opening downwards into the part of the outwardly enlarged rotary drum, and does not reach the interior of the container.
  • an apparatus whereby the water used is reduced to such an extent that it only insignificantly increases the overall loading weight.
  • heavy garbage such as domestic garbage
  • disintegration is effected so as to prevent cavities in material dumped on a garbage pile, which would have the undesired result of a fire risk or housing rat colonies.
  • lightweight garbage of paper, cardboard orthe like shouldbe extensively softened or soaked to allow the tamping to be increased in the collecting container, so that the carrying capacity of the vehicle is utilized to a maximum extent and without the weight of the added water being a noticeable proportion of the contents.
  • this advantage is effected by introducing steam, preferably superheated steam, into the interior of the collecting container.
  • the steam because of its gaseous state, fills the whole container and penetrates its load, so that all particles of garbage are dampened as required for disintegration without causing excessive wetting.
  • the heat of thesteam increases the disintegration effect, and the use of superheated steam has a particular advantage. It also increases the putrefaction effect, and thus causes the garbage to reach the pile or dump in a pre-compostlike state.
  • the weight of the water precipitated in the garbage from the steam is only about one-fifth of the weight of water which would have been required if added as a liquid to the container.
  • the stock of water required to be carried by the vehicle is accordingly reduced.
  • the full volumetric capacity of the container can be used; in the case of light-weight garbage, the increased compressi bility, which is about twice that of undampened lightweight garbage, can be utilized to the fullest.
  • a garbage loading truck for carrying out the new method in accordance with a feature of the invention includes a steam connecting pipe at the closed end face of the collecting container.
  • the pressurized steam tends to flow towards the opposite end face of the container, at the loading side, which communicates with the outer atmosphere. During this flow, the steam traverses the entire container space and thus permeates all of the contents thereof.
  • the new method is readily carried out in that the steam connecting pipe of the collecting container is connected to a stationary steam generator, such as remote steam heating installation.
  • a stationary steam generator such as remote steam heating installation.
  • the invention utilizes a steam generator adjacent to the water storage container. Due to the relatively small amount of water to be carried, small steam generators are available the weight of which is so low that it amounts to only a fraction of the water to be carried.
  • the use of the invention is independent of the type of collecting container. It is, however, particularly effective when a known rotary drum is used, the pivot pin of which is located at the closed end face wall and is provided with an axial bore used to introduce the steam.
  • the steam during the garbage tumbling action of the rotary drum, penetrates all garbage particles. Even during loose filling, the volume of the material loaded is reduced to such an extent that the tumbling movement causes considerable tamping.
  • the loading device of the rotary drum is fitted with a known compacting device, e.g., in the form of a helical thread inwardly rising inside the wallof the cover, the invention provides a very high degree of compacting.
  • FIG. I is an overall schematic view of the garbage truck.
  • FIG. 2 is an enlarged view of the means for steam introduction.
  • the garbage truck has a frame 1 with road wheels 2 and a driving cab 3, as shown in FIGS. 1 and 2.
  • frame 1 On frame 1, there is a rotary drum container 4 and its closed end face wall 5 is connected to the frame by means of a bearing support. There are bearing rollers, not shown, at the other end of the drum.
  • a pipe 9 leads to a pump 10, and then to a steam generator 11, which is heated by an oil burner 12.
  • a steam pipe 13 rising therefrom leads to an axial bore in the pivot pin 6, as shown in detail in FIG. 2.
  • the opposite end rotary drum 4 is closed by a cover 14, cooperating with a conveyor and compacting device, the cover being hinged open when garbage is to be introduced.
  • Cover 14 provides a sufiiciently tight seal on the back end of drum 4 so that superheated steam may be introduced into the container under pressure.
  • a conveyor such as shown in applicant's copending application, Ser. No. 841,199, filed on July 14, 1969, and now U.S. Pat. No. 3,598,262, may be attached to the back of the vehicle to move garbage into drum 4.
  • the compacting device may consist of a helical screw or tamper disposed within drum 4.
  • a garbage collection truck having a rotatable collection container for tumbling garbage disposed therein, apparatus for dampening and disintegrating the garbage contained in the collection container, comprising:
  • an oil-fired steam generator coupled to said water storage container, and mounted on the garbage truck;
  • a water pump coupled to said water storage container and said steam generator, for pumping water from said container to said steam generator;
  • a steam supply pipe disposed through one end of the garbage truck collection container, and coupled to said steam generator, for admitting steam into the collection container of the garbage truck
  • said collection container of the garbage truck is cylindrical in shape, and is supported at one end by a cylindrical pivot pin about which the collection container rotates, said pivot pin includin a c ylir 1 dncal bore through which said steam supp y pipe is disposed for admitting steam into the garbage collection container.
  • the garbage collection container further comprises a loading door for sealing the collection container loading opening during treatment of the garbage in the collection container with said steam.
