Description

  The present invention relates to a food waste bag breaking and sorting machine that breaks a garbage bag containing food waste and separates it into a food waste and a garbage bag.

  Food waste discharged from households and canteens is usually collected in a plastic garbage bag. When food waste is fermented, the garbage bag is broken with a bag separator. Bags are separated into food waste that can be biologically processed and waste bags that cannot be biologically processed.

  As such a food waste bag-breaking and sorting machine, conventionally, a bag-breaking and sorting machine disclosed in Patent Document 1 and Patent Document 2 has been used.

  4A and 4B are diagrams showing the food waste bag-breaking and sorting machine, in which FIG. 4A is a front view of the bag-breaking and sorting machine, FIG. 4B is a cross-sectional view taken along the line A-A in FIG. FIG. 4D is a plan view of an upper casing constituting the sorting machine, and FIG. 4D is a plan view of a lower casing constituting the bag-breaking sorter.

  This bag-breaking and separating machine is provided with a horizontally long drum body 23 composed of an upper casing 21 and a lower casing 22 and a spiral projection on the inner wall of the upper casing 21 of the drum body 23. The guide plate 24 is composed of a rotating shaft 25 supported along the axial direction of the drum body 23 and an impeller 27 composed of four rotating blades 26.

  More specifically, the bag-breaking and sorting machine is configured such that a garbage bag containing food waste is fed into the drum body 23 from a loading port 28 provided in the upper casing 21. Within the drum body 23, the four blades 26 of the impeller 27 are rotating at high speed so as to be in contact with the front end of the guide plate 24 and the inner wall surface of the lower casing 22, and are put into the drum body 23. The garbage bag moves along the axial direction from the position of the insertion port 28 while being guided by a plurality of guide plates 24 provided in the drum body 23 so as to be inclined with respect to the axis. Then, the impact force of the four blades 26 and the shearing force generated between the blades 26 and the lower casing 22 are destroyed, and the garbage bags are crushed into food strips.

  The lower casing 22 is a screen provided with a number of punching holes 29, and the crushed food waste passes through the punching holes 29 of the lower casing 22 and is discharged downward.

  On the other hand, the garbage bag broken in a belt shape is not discharged from the punching hole 29 of the lower casing 22, moves in the drum body 23 along the guide plate 24 in the axial direction, and the upper casing 21 is inserted. It is discharged from a garbage bag discharge port 30 provided at the end opposite to the end provided with the port 28.

Note that the food waste that passes through the punching hole 29 of the lower casing 22 and is discharged downward is a cart provided below the lower casing 22 as shown in the cross-sectional view of FIG. It is collected in the central part by the part 31 and collected by a screw conveyor or the like (not shown).

  However, the food waste bag-breaking and sorting machine disclosed in Patent Document 1 and Patent Document 2 described above has a problem that the input is not processed smoothly as described below.

  (1) Since the central position of the garbage bag inlet is located close to the axis of the upper casing, the food waste and garbage bags that have been bounced off by the feathers of the impeller are placed in front of the inlet in the rotational direction. A phenomenon occurs in which food waste and garbage bags adhere to the side wall and fall when hitting the side wall, and as a result, the input material stays in the vicinity of the input port.

  (2) Treating moss with a moisture content of 80% or more, powders with low moisture content, granular materials, etc. is no problem, but when treating food waste with high viscosity, that is, sticky such as udon, rice When processing food (including starch) or food waste with a moisture content of about 50 to 70%, the food waste adheres to the waste bag and the food waste and the waste bag cannot be easily separated and separated. , Food waste collection rate will decrease.

  (3) Food waste adheres to and accumulates in the narrow gap between the skirt and the lower casing (especially on both sides of the lower casing) to fill the gap, and the food waste is removed from the lower casing. Since the area that can be discharged is reduced, the discharge of food waste from the drum is delayed, and finally the motor for rotating the impeller is tripped. When this happens, it is necessary to open the inspection port of the bag-breaking sorter, remove the food waste left inside, and start it up again after it has no load, greatly reducing the labor and time of workers. Will spend. Furthermore, the food waste adhering to and accumulating in this way rots and causes a bad odor.

  The present invention has been made in view of the above circumstances, and in a food waste breaking bag sorting machine that breaks a garbage bag containing food waste and separates it into a food waste and a garbage bag. An object of the present invention is to provide a food waste bag-breaking and sorting machine capable of efficiently carrying out bag breaking and sorting by suppressing the accumulation and adhesion of garbage inside the bag-breaking and sorting machine.
