Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a food waste disposal device suitable for processing food waste that is relatively soft and contains a large amount of water, such as fruits and vegetables and leftover food.

(Background of the Invention) Food waste, such as fruit and vegetable waste and leftover food, is conventionally often disposed of by burying it directly in the ground or incinerating it. In general, food waste such as fruits and vegetables and leftover food has a high moisture content and low solid content, but is bulky, so disposing of it requires a large space to bury, and requires a lot of incineration fuel and a long incineration time. was necessary.

For this reason, when disposing of food waste such as fruits and vegetables and leftover food, it is desirable to crush the waste and remove moisture beforehand. In particular, if dehydration and pulverization can be performed at the same time, it can be expected to improve the efficiency of waste treatment. (Objective of the Invention) The present invention was made in view of the above circumstances, and it provides a raw material that can simultaneously crush and dehydrate food waste such as fruits and vegetables and leftover food, thereby significantly increasing waste processing capacity. The purpose is to provide garbage disposal processing equipment.

(Structure of the Invention) Such an object of the present invention is to include an outer rotor having a small hole for dewatering and being rotationally driven, and an inner rotor rotating in the same direction as the outer rotor at different speeds, and the outer rotor This is achieved by a food waste disposal apparatus characterized in that the food waste is simultaneously crushed and dehydrated in the gap between the food waste and the inner rotor.

(Embodiment) Fig. 1 is a side sectional view of one embodiment of the present invention, and Fig. 2 is its I
It is a sectional view taken along the line I-H.

In FIG. 1, reference numeral 10 indicates a lower chamber, which is formed into a substantially cylindrical shape and opens in the vertical direction. A thrust bearing 12 is provided at the upper opening of the lower chamber 10.
The outer rotor 14 is rotatably held via the outer rotor 14. A large number of blades 16 are provided on the inner periphery of the outer rotor 14 so as to extend toward the central axis thereof, and a large number of small holes 18 for dewatering are provided between these blades 16. The outer surface of the outer rotor 14 and the upper part of the lower chamber 10 are covered by a water collecting chamber 20, and a drain port 22 is provided at the lower part of the water collecting chamber 20.
is connected.

Reference numeral 24 denotes an upper chamber, and the inner edge of the upper opening of the outer rotor 14 is held by a bearing 25 in the circular lower part of the upper chamber. The outer rotor 14 is therefore held at its upper part in the upper chamber 24 and at its lower part in the lower chamber 10, with each bearing 12.25 being hermetically sealed. Note that a sealing material is installed between the outer rotor 14 and the upper part of the water collection chamber 20. 26 is a motor for rotationally driving this outer rotor 14, and the rotation of this motor 26 is as follows:
The power is provided by the outer rotor 14 via a worm 28, a worm gear 29, a spur gear 30, and a gear 32 fixed to the upper outer periphery of the outer rotor 14.

A hollow rotating shaft 34 is rotatably fitted into the upper part of the upper chamber 24 . This hollow rotating shaft 34 is located around the center axis of the upper chamber 24 and the outer rotor 14, and its upper part penetrates the upper chamber 24 and protrudes upward, and its lower part is supported by a bearing 35 held in the lower chamber 10. be done. An inner rotor 36 is attached to the lower part of this rotating shaft 34. The inner rotor 36 is formed into a substantially conical shape with a bottom, and a number of blades 38 are provided radially projecting from the conical surface. As shown in FIG. 1, the blades 16 of the outer rotor 14 and the blades 38 of the inner rotor 36 are arranged on a circumference along a plane perpendicular to the rotation axis 34, and the blades 16 and 38 of the outer rotor 14 interfere with each other. They are arranged in multiple stages so that they can be approached easily. As will be described later, food waste such as fruit and vegetable waste is fed from above between both rotors 14, 36, and the waste is cut and pulverized by the relative rotation difference between the blades 16, 38 of both rotors 14, 36.

The distance between the blade 16 and the outer peripheral surface of the inner rotor 36, the distance between the blade 38 and the inner peripheral surface of the outer coater 14, and the distance between the blades 16. Each is shorter. For this reason, food waste thrown in from above is pulverized into finer particles as it moves downward. A worm gear 40 is attached to the upper part of the rotating shaft 34 , and the inner rotor 36 is rotationally driven by the motor 44 via the worm 42 , the worm gear 40 , and the rotating shaft 34 . Note that this inner rotor 36 is directed in the same direction as the outer rotor 14 and in the same direction as the outer rotor 1.
Rotates faster than 4. Unilateral rotor 14 rotates at a slower speed than inner rotor 36 and at a speed sufficient to centrifuge the water. Therefore, the garbage is cut and crushed between the blades 16 and 38, while the water contained therein is centrifuged and dehydrated through the small dehydration holes 18 of the outer rotor 14. .

46 is a screw compressor that transfers food waste into the L section chamber 24, compresses food waste led from a hopper 48 (described later), preliminarily separates moisture, collects this water in a lower tray 47, and drains it. do. Further, by adjusting the rotational speed of the screw compressor 46, the processing speed of the garbage processed by the inner rotor 36 and the outer rotor 14 is adjusted.

48 is a hopper that guides food waste to the screw 46;
A rotary blade 50 and a fixed blade 52 are provided in the passageway to cut the thrown garbage into appropriate sizes. Reference numeral 54 denotes a grid-shaped cutter that shreds the garbage transferred by the screw pressurizer 46 and throws it into the upper chamber 24.

Note that the rotating shaft 34 and the inner rotor 36 each have a small hole 56.
58 is provided, and hot air is forced into the inner rotor 36 and the outer rotor 14 through a pipe 60 communicating with the L end of the hollow rotating shaft 34.
It bursts out between. This hot air removes moisture from the crushed food waste by the blades 16.38, passes through the small dehydration holes 18, and is exhausted from the duct 62.

Next, the operation of this garbage disposal device will be explained.

Food waste such as fruit and vegetable waste placed in the hopper 48 is roughly cut by a rotating blade 50 and a fixed blade 52, and then enters the screw compressor 46. Here the waste is preliminarily compacted and
Water droplets are collected on a tray 47 and discharged. The waste compressed by the screw compressor 46 is further shredded by a lattice cutter 54 and fed into the upper chamber 24 at a constant transfer speed.

The input garbage such as fruit and vegetable waste is cut into fine particles between the blade 38 that rotates at high speed together with the inner rotor 36 and the blade 16 of the outer rotor 14 that rotates at low speed in the same direction. The waste is first cut relatively coarsely by the upper blade 16.38, and as it falls to the lower blade 16.38, the gap between the blades 16.38 decreases and the waste is shredded into finer pieces. .

In this way, the finely pulverized waste is
6.38 falls into the lower chamber 10 through the lower gap and is discharged through the lower opening of the lower chamber 10.

On the other hand, while the waste is crushed between both rotors 14.36, the water contained in the waste is dehydrated by centrifugal force.
Drain port 22 passes through small hole 18 for dehydration and water collection channel 20
drained from the water. Further, since hot air is blown between the two rotors 14 and 36 via the rotating shaft 34, the crushed solid material is also efficiently dried. In this way, the moisture in the waste is efficiently dehydrated, and the waste after pulverization is reduced to solid matter, making subsequent processing easier.

In the above embodiment, the inner rotor 36 was rotated at a higher speed than the outer rotor 14, but the outer rotor 14 may be rotated at a higher speed than the inner rotor 36, or the inner rotor may be fixed.

Further, in this embodiment, a large number of blades are provided on both rotors 14. Of course, it may also be a device that crushes and crushes objects.

In this embodiment, hot air is introduced between the inner and outer rotors 14 and 36, but a great effect can be obtained by simply sending unheated air at room temperature. Note that the present invention also includes a device in which hot air or air is not sent here.

Further, in this embodiment, the waste is sent to the screw compressor in fixed amounts by the hopper 48, where it is preliminary dehydrated and finally introduced between the rotors 14 and 36 to be pulverized. That is, 2
Since dehydration is performed in stages, dehydration can be done efficiently.

In addition, since the rotary blade 50 provided in the hopper 48 is used as the first stage, the lattice cutter 54 is used as the second stage, and the rotor 14.36 is used as the final stage, an appropriate cutting device can be used for each stage. Can be processed efficiently and continuously.

(Effects of the Invention) As described above, the present invention rotates the inner rotor and the outer rotor having small holes for dehydration at different rotational speeds, thereby crushing and dewatering food waste such as fruit and vegetable waste and leftover food. This can be done simultaneously and continuously, and the processing capacity of food waste can be greatly improved.
