JPS63137792A - Disposer for grinding, kneading and granulating of garbage - Google Patents

Abstract

PURPOSE:To easily dispose of garbage, by grinding the org. substance of the garbage and kneading a dehydration additive based on a calcareous substance with the ground garbage before granulating the resulting kneaded mixture. CONSTITUTION:Garbage is charged in a garbage charge hopper 4 and ground by the blade 6 of a grinding fixed blade plate to be allowed to fall in a lower kneading casing 16. After the water content of the garbage is sensed, a dehydration additive is quantitatively added to the kneading casing 16 from a dehydration additive tank 2 and a partition plate 21 through a rotary measuring valve 15. Dehydration reaction is generated while the garbage and the additive are kneaded by a kneading rotary shaft 12 and a kneading blade scooping plate 11, and dehydration drying and sterilizing action are applied within a short time to granulate the kneaded mixture. Further, in order to discharge the malodor generated at the time of the dehydration reaction, an exhaust blower 22 and a deodorizer 23 are arranged. By this method, the practical use of the granulation disposal can be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves crushing organic matter with a high water content in kitchen waste generated from kitchens such as feeding centers and ships, and kneading it with a dehydrated additive mainly composed of calcareous matter. This invention relates to an apparatus for crushing, kneading, and pulverizing organic kitchen waste for the purpose of dehydrating, drying, and pulverizing organic kitchen waste by crosstalk reaction to remove the foul odor of rotten organic waste and reduce its weight.

Traditionally, kitchen waste is crushed in water and the processed material is disposed of into the sewer, or
In the case of underwater crushing and dehydration/drying, the dewatering process is carried out into the sewer system or into a wastewater treatment system, which requires additional equipment, resulting in high costs.

High-speed dewatering equipment for pulverizing livestock manure, manufacturing sludge, etc., has also appeared on the market, but problems remain in its practical application due to incomplete countermeasures against bad odors and dust during processing, and it has not been used for kitchen waste. No practical device has appeared.

Commercial kitchen waste has a high moisture content of 85 to 95%, so it is not eligible for disposal in public incinerator facilities, and is disposed of by specialized disposal companies for a fee.

The present invention solves the above-mentioned problems and has the advantage of embodying various elements for practical use.It processes kitchen waste by turning it into powder and granules, so there is no need to treat wastewater, and the processed material has a low water content. Adjustment is possible, and the capacity for water content treatment within 35% to 50% can be reduced as necessary.

During kneading, the inside of the kitchen waste is sterilized by the heat of reaction with the dehydration additive, and the granulated product is rendered harmless.As time passes, the processed product is air-dried at the temperature retained in the body, reducing the moisture content to 10. Since the waste is combustible, it is possible to use a public incinerator facility and collect it free of charge as processed kitchen waste.

The processing device of the present invention is constructed by incorporating the pushing, crushing, kneading, deodorizing, and dusting mechanisms into a box-shaped body,
The purpose is to provide a mechanism that is small, inexpensive, easy to handle, and has excellent workability.

Embodiments of the present invention will be described based on FIGS. 1, 2, 3, and 4.

The box-shaped main body shown in Figure 1 includes a kitchen waste input opening 2 and a kitchen waste input hopper 4. 4. A certain amount of kitchen waste is placed in the kitchen waste input hopper. 5. Rotating arm that pushes kitchen waste when thrown inside. The crushing rotary blade blade 7.
and Dobe hinge 24. 6. Fixed vane plate blade for crushing supported at one end by The kitchen waste is crushed by the meshing of the lower kneading box 1.
6. to fall.

The moisture content of the kitchen waste is sensed in advance, and the dehydration additive tank 3, the partition plate 21. From rotary mass valve 15. 16. The crushed kitchen waste added to the container is shown in Figure 2.
Kneading rotating shaft 12. While kneading with the kneading blade scoop plate IL, a dehydration reaction occurs, and in a short time, dehydration and drying and sterilization effects are achieved and the product is turned into powder. Rotary drive source electric motor 17. is the timing belt 18. and timing belt 19. and timing belt 20. to reduce the rotational speed and convert it to the required rotational speed, and press the rotating arm shaft 9. Then, the crushing rotary blade blade shaft 10° and the kneading rotary shaft 12 are driven to rotate. The odor generated during the dehydration reaction of kitchen waste inside the kneading box 16° shown in FIG. 1 is turned into exhaust steam and is discharged outside the box. to be placed.

Also, kneading box 16. Kneading box 16. A take-out gate 14° and an operating lever 13 interlocked with the gate are provided at the bottom of the. and take-out gate 14. At the bottom is a dust prevention mechanism 25. to be placed.

Figures 3 and 4 show the kitchen waste crushing mechanism and the kitchen waste input hopper 4. Inside the push-in rotary arms 5. The crushed material is crushed by rotary blade blade for crushing 7. If a high-hardness substance is accidentally inserted when the blades of the fixed vane plate 6.0 are engaged with each other, the tip of the high-hardness substance such as a spoon, knife, fork, etc. will be inserted into the electric motor 17 due to the engagement action of the tips of the trapezoidal cutting edges. ．． makes an emergency stop.

In the case of a trapezoidal blade, the actual crushing action used for crushing is on the side parts, so the structure is such that high hardness materials can be taken out and work can be continued. Also, fixed blade plate for crushing6. As mentioned above, the upper part is hinged 24. 8. A compression spring is installed in the center of the fixed plate to jointly change the solid content of the crushed material. Effects of practical application of crushing, kneading, and granular treatment of kitchen waste, which has a structure that allows it to swing while maintaining a constant stroke and also performs the action of a hummer, and is suitable for actual action. There is.
