Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garbage recycling vehicle for recycling raw garbage into compost, livestock / culture feed, and the like. In the present invention, raw garbage refers to raw garbage discarded from households, food residues and cooking scraps such as vegetable meat discarded from distribution processes (restaurants, hotels, retail distribution), and animals from food processing factories. Organic waste generated from sexual residues, agriculture, forestry and fisheries.
[0002]
[Prior art]
In recent years, the above-mentioned garbage has problems on the disposal side, such as the occurrence of corruption, an increase in the garbage storage area, or an increase in the collection fee to the processing company. The processing company has increased the collection and transportation costs, There are problems such as shortage, and the local government has problems such as incinerators and landfill measures, and volume reduction and volume reduction of garbage are major issues.
[0003]
In order to solve this problem, there is conventionally known a technology in which a garbage processing device is mounted on a garbage truck, and the garbage is fermented and decomposed by microorganisms while the vehicle is running to recycle the garbage ( For example, see JP-A-8-12005).
[0004]
[Problems to be solved by the invention]
However, the above-mentioned food waste is usually disposed in a plastic bag made of synthetic resin and discarded. Especially, expired foods that are discarded in the distribution process are discarded in a synthetic resin tray. Is put into the above-mentioned conventional garbage processing equipment as it is, the optimal fermentation conditions due to microorganisms cannot be obtained, so it takes time to treat the garbage, and in the recycled product, garbage bags, trays, etc. Wrapping material is mixed in and the commercial value is lost. Therefore, there is a problem that it takes a lot of time and labor because it is necessary to separate the garbage and the packaging material such as garbage bags and trays before putting them into the garbage processing apparatus.
[0005]
The present invention solves the above-mentioned conventional problems, and provides a garbage recycling vehicle that can recycle garbage by separating garbage and packaging materials while the vehicle is running. With the goal.
[0006]

In the present embodiment, food or the like is stored in the tray 2d and the food is covered with a film or lid. However, food stuffed in a garbage bag is processed in the same manner. is there.
[0010]
The packaging material crushing device 3 is disposed on the exit side of the garbage transport device 2 in the upper part of the vehicle 1, and as shown in FIGS. 1 and 3, a rotating shaft 3b is disposed in a cylindrical crushing housing 3a. The rotating shaft 3b is provided with a plurality of stirring blades 3c, and a protruding piece 3d is formed in front of the tip of the stirring blade 3c. In addition, the rotating shaft 3b of the packaging material crushing device 3 is provided integrally with a rotating shaft 4e of the packaging material sorting device 4 described later. Then, when the food tray 2d enters the crushing housing 3a from the dust transport device 2, the protruding piece 3d crushes the film or lid covering the tray by the high speed rotation of the stirring blade 3c (in the direction of the dotted arrow in the figure). In a state where the garbage is separated, it is sent to the packaging material separation device 4 in the next step.
[0011]
As shown in FIGS. 1 and 4, the packaging material sorting device 4 includes a cylindrical sorting housing 4a. A sieving portion 4b is formed in the lower portion of the sorting housing 4a, and a tray is disposed above the left end of the sorting housing 4a. An outlet 4c is formed, and a rib 4d protrudes spirally inside the sorting housing 4a. A rotation shaft 4e is disposed at the center of the sorting housing 4a. The rotation shaft 4e is provided with a plurality of stirring plates 4f, and the tips of the stirring plates 4f are in contact with the ribs 4d.
[0012]
When the stirring plate 4f rotates, wind is generated in the sorting housing 4a from the right to the left in FIG. 1 by the action of the spiral rib. The tray and garbage that have entered from the packaging material crushing device 3 are conveyed from right to left by the rotation of the stirring plate 4f, and the tray is sent to the packaging material compression device 5 from the tray outlet by wind. On the other hand, the garbage is crushed by the stirring plate 4f and the rib 4d, and the fine garbage is sent to the garbage decomposing apparatus 6 through the hole of the sieving portion 4b.

[0015]
An exhaust pipe (not shown) of the engine is connected to the deodorizing device 7, and harmful components in the exhaust gas of the engine and malodorous components of the garbage decomposition device 6 are removed by a catalyst.
[0016]
In the decomposition housing 6a, microorganism carriers such as sawdust and wood chips inhabited by microorganisms and fermentation aids are charged in advance. When mixed with auxiliaries, the garbage becomes an aggregate structure in which microorganisms are always supplied evenly. By making sufficient contact between these and air, the garbage is decomposed at high speed by microorganisms. . At this time, the heater 6g and the water sprinkler 6h are controlled so that the fermentation conditions of the garbage are optimized, and the fermentation temperature, pH value, and moisture content of the processed product are automatically controlled so as to become desired values. .
[0017]
As shown in FIGS. 1 and 2, the rotating shaft 4e of the packaging material sorting device 4 is connected to a driving pulley 9, the rotating shaft 6c of the garbage disassembling device 6 is connected to a driving pulley 10, and the packaging material compressing device. The ball screw shaft 5b is connected to the forward / reverse drive mechanism 11, and the drive pulleys 9, 10 and the forward / reverse drive mechanism 11 are driven by an engine of a garbage recycling car (not shown). An electric motor or a hydraulic motor may be employed instead of the engine.
