Abstract

PROBLEM TO BE SOLVED: To improve garbage agitation efficiency by providing blades in such a way that angular intervals in the circumferential direction of a rotary shaft between respective blades become irregular. SOLUTION: Inclination angles of blades 26a-26d on a rotary shaft 25 to a horizontal plane in a tank 17 are set to be gradually larger as it goes from the first blade 26a at the lowest end to the forth blade at the uppermost end. As viscosity of garbage in the treatment tank 17 becomes higher, spirally linked garbage are pushed up by the respective blades 26a-26d, and the blades 26a-26d get in contact with it at irregular intervals in garbage extended directions. Push-up force by the blades 26a-26d thus operates to plural positions in the garbage at irregular intervals in its extension directions, so the spirally linked garbage are broken. It then drops to a lower part of the treatment tank 17.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device.

[0002]

2. Description of the Related Art Conventionally, an apparatus for treating food waste has a processing tank into which food waste is put, and an air supply pipe for connecting heated air to the processing tank is connected to the processing tank. A rotary shaft extending in the vertical direction is rotatably supported in the processing tank, and the rotary shaft is provided with a plurality of blades along the vertical direction. Then, when the rotary shaft is rotated, each blade is adapted to rotate with the rotation of the rotary shaft. The blades are arranged in a spiral shape that sequentially turns in the direction opposite to the rotation direction of the rotating shaft and rises, and the angular intervals between the blades with respect to the circumferential direction of the rotating shaft are equal. Further, each blade is inclined so as to descend from the rear end in the rotation direction toward the front end.

When using the above-mentioned garbage processing apparatus, garbage is put into the processing tank so that each blade is filled with the garbage, and further, a treating agent composed of enzyme and bacteria is put into the processing tank. . In this state, the heated air flows from the air supply pipe into the processing tank, and the rotary shaft is rotated, so that each blade is rotated with the rotation of the rotary shaft.

When each blade is rotated, the raw dust on the rotary orbit of each blade is pushed up to the rotary orbit of the vane located on the one upper side of the blade, so that the raw dust in the processing tank is removed. It is pushed upwards from the bottom up. And the garbage that was pushed up by the uppermost blade,
The blades fall from the rear side in the rotation direction to the lower part of the processing tank.
Then, by repeating the above operation, the raw waste in the treatment tank is stirred and the treatment agent is mixed with the raw waste.

When the raw dust is agitated to increase the viscosity of the raw dust, the raw dust located on the upper side of each blade may be connected to form a spiral shape. When the garbage connected in a spiral shape is pushed up by each blade, the blades come into contact with each other at equal intervals in the extending direction of the garbage. Therefore, the pushing-up force by each blade acts on the raw garbage at a plurality of positions at equal intervals in the extending direction of the raw garbage,
The garbage that is connected spirally rises spirally in the direction that connects each blade without breaking. Then, when the garbage connected in a spiral shape protrudes from the rear end of the uppermost blade in the rotation direction, the protruding garbage is cut off and falls from the rear side of the uppermost blade in the rotation direction.

When the garbage mixed in the processing tank as described above comes into contact with the air flowing into the processing tank from the air supply pipe, the garbage is decomposed by the processing agent to become, for example, organic fertilizer.

[0007]

However, in the above-mentioned food waste treating apparatus, as the food waste is decomposed by the treatment agent, the volume of the food waste is reduced and the uppermost blade is stored in the processing tank. Exposed from dust. At this time, if the raw dust has a high viscosity, even if the raw dust connected in a spiral shape is pushed up by each blade, the raw dust cannot reach the uppermost blade. As a result, there is a problem in that the raw garbage connected in a spiral shape does not stick to each blade and does not drop downward, and the stirring efficiency of the raw garbage in the processing tank decreases.

The present invention has been made to solve the above problems, and a first object thereof is to improve the stirring efficiency of garbage. The second purpose is to prevent the supply hole from being blocked by garbage.

A third object is to efficiently drop the garbage in the processing tank when all the blades are filled with the garbage in the processing tank.

[0010]

In order to achieve the above object, in the invention described in claim 1, the blades are provided so that the angular intervals between the blades with respect to the circumferential direction of the rotary shaft are not uniform.

According to the second aspect of the present invention, a supply port for supplying air into the processing tank is provided at a position corresponding to the lowermost blade in the processing tank, and the lowermost blade and the second blade from the bottom are provided. The angular interval between the second blade from the bottom and the third blade from the bottom was set smaller than the angular spacing between the second blade and the third blade from the bottom.

According to the third aspect of the present invention, a pair of blades positioned vertically intermediate between the lowermost blade and the uppermost blade has an angular interval lower than the blades. Greater than the angular spacing between.

That is, according to the first aspect of the present invention, in a state where the viscosity of the raw dust in the processing tank is high, when the rotary shaft is rotated to stir the raw dust with each blade, the raw dust located above each blade is Are connected to form a spiral. When the garbage connected in a spiral shape is pushed up by the blades, the blades are in contact with each other at a non-uniform interval in the extending direction of the garbage. As a result, the push-up force of each blade acts on a plurality of portions of the raw garbage that are arranged at non-uniform intervals in the extending direction of the raw garbage, and the raw garbage that is spirally connected is cut off. Then, the cut garbage is dropped from the space between the blades having a large angular interval to the lower part of the processing tank.

According to the second aspect of the invention, in addition to the operation of the first aspect of the invention, when the blade at the lowermost end pushes the garbage, a gap is formed at the rear side in the rotation direction of the blade, and the gap is supplied to the gap. Air is supplied from the mouth. Then, when the garbage connected spirally on the upper side of each blade is torn, the torn garbage does not fall from between the blade at the bottom and the blade from the bottom to the second from the bottom. It falls between the blade and the third blade from the bottom.

According to the third aspect of the present invention, the first or second aspect is provided.
In addition to the action of the described invention, in a state where each blade is filled with the garbage in the processing tank, when the garbage connected spirally on the upper side of each blade is torn, the chopped garbage is at least at the bottom end. It falls from between a pair of blades located in the vertical middle between the blade and the uppermost blade, and from the rear side in the rotation direction of the uppermost blade.

Further, on the outer side surface of the main body case 12, there is provided an outlet 48 for taking out the organic fertilizer produced by decomposing the garbage with the treating agent from the treating tank 17.

Next, the operation of the food waste processing apparatus 11 configured as described above will be described. When the connecting pipe 44 is rotated in the upright direction with the axis of the rotating pipe 46 as the center, the lid 43 is separated from the charging hole 42 and the charging hole 42 is opened. Then, the garbage is introduced into the processing tank 17 through the introduction hole 42 so that the first to fourth blades 26a to 26d are filled with the garbage. Further, from the input hole 42 to the processing tank 1
A treatment agent composed of an enzyme such as amylase, protease and lipase and a bacterium is put into 7. After that, when the connecting pipe 44 is rotated in the opposite direction to the above, the lid 43 is closed.
2 and the charging hole 42 is closed.

When the blower electric motor 33 drives the blower 32 to supply air from the discharge port 32a into the air supply pipe 34, the air is heated by the heater when flowing through the air supply pipe 34. The air heated by the heater is sent out from the air supply pipe 34 to the air supply passage 19, and further supplied from the air supply passage 19 into the processing tank 17 through the supply hole 20.

When the output shaft 29a of the transmission 29 is rotated by driving the rotary shaft electric motor 31, the output shaft 29a is rotated.
Is transmitted to the rotary shaft 25 by the coupler 30, and the rotary shaft 25 is rotated in the direction of arrow A in FIG. Rotating shaft 25
When is rotated, the first to fourth blades 26a to 26d are rotated about the axis of the rotating shaft 25. Each blade 26a-26
When d is rotated, the garbage located on the rotation orbits of the blades 26a to 26d is pushed up by the blades 26a to 26d onto the rotation orbits of the blades 26a to 26d located on the upper side. As a result, the garbage in the processing tank 17 is sequentially pushed upward from below by the blades 26a to 26d. By this pushing-up operation of the raw dust, the treatment agent is mixed with the raw dust and the raw dust in the processing tank 17 is stirred.

When the first blade 26a pushes up the garbage located on its rotation orbit, a gap is formed on the rear side of the first blade 26a in the rotation direction. Therefore, the air supply passage 19
The air blown into the processing tank 17 from the inside through the supply pipe 20 is blown toward the gap and is blown from the supply hole 20 without being subjected to the resistance of the garbage. Then, when the air comes into contact with the garbage that is agitated in the processing tank 17, the garbage is decomposed by the treating agent.

When the raw dust in the processing tank 17 is agitated to increase the viscosity of the raw dust, the raw dust located above the blades 26a to 26d may be connected to form a spiral shape. When the garbage connected in a spiral shape is pushed up by the blades 26a to 26d, the blades 26a to 26d come into contact with each other in a non-uniform interval in the extending direction of the garbage. Therefore, the push-up force by each of the blades 26a to 26d acts on a plurality of portions of the raw garbage which are arranged at non-uniform intervals with respect to the extending direction of the raw garbage, so that the raw garbage connected in a spiral shape is broken. And, the torn pieces of garbage are
It does not fall from between the first and second blades 26a and 26b, but falls from between the second and third blades 26b and 26c and from the rear side in the rotation direction of the fourth blade 26d to the lower portion of the processing tank 17. To do.

After that, when the decomposition of the raw dust by the treating agent progresses, the volume of the raw dust decreases and the fourth blade 26d is exposed from the raw dust stored in the processing tank 17. At this time, if the raw dust has a high viscosity, even if the raw dust connected in a spiral shape is pushed up by the blades 26a to 26c, the raw dust cannot reach the fourth blade 26d. Even in this case, the garbage connected in a spiral shape is generated in each of the blades 26a to 26a.
When pushed up by 6c, each blade 26a-26d
Since the push-up force due to acts on the raw garbage at a plurality of locations with non-uniform intervals in the extending direction of the raw garbage,
The garbage that is spirally connected is cut into pieces. Then, the shredded raw dust does not fall between the first and second blades 26a and 26b, but falls between the second and third blades 26b and 26c to the lower portion of the processing tank 17.

After that, when the decomposition of the garbage by the treating agent progresses, the garbage becomes an organic fertilizer, for example. If the garbage in the processing tank 17 scatters toward the lid 43 during circulation, the scattered garbage enters the connecting pipe 44.
The insides of the connecting pipe 44 and the rotating pipe 46 are clogged or soiled with raw dust. In this case, the lid 43 and the connecting pipe 44 are rotated so that the connecting pipe 44 stands up. Then, the garbage in the connecting pipe 44 is washed away with water to remove clogging and dirt in the connecting pipe 44. The water from which the garbage in the connecting pipe 44 is washed away flows from the inside of the connecting pipe 44 to the exhaust pipe 47 via the turning pipe 46.

Since the connecting pipe 44 and the turning pipe 46 are connected in a T-shape, it is difficult to remove clogging and dirt in the turning pipe 46 from the connecting pipe 44 side. In this case, if the cap 49 is removed from the rotary pipe 46 and the cleaning port 46a of the rotary pipe 46 is opened, the rotary pipe 4 is opened from the cleaning port 46a.
It is possible to easily remove clogging and dirt in the inside of 6.

In this embodiment described in detail above, the following (a)
(G). (A) Since the angular intervals of the rotary shaft 25 between the blades 26a to 26d with respect to the circumferential direction are not uniform, the blades 26a to 26d are not uniform.
It is possible to shred high-viscosity garbage that is spirally connected on the upper side of a to 26d. That is, when the garbage connected in the spiral shape is pushed up by each of the blades 26a to 26c, the pushing force of each of the blades 26a to 26d is unevenly spaced in the extending direction of the garbage. Since it works at a plurality of places, it is possible to shred the garbage that is connected in a spiral shape. Then, even when the fourth blade 26d is exposed from the garbage in the processing tank 17, the spirally connected garbage is cut into pieces, so that the cut pieces are separated into the second and third blades 26b, 26b. It can be dropped from between 26c to the lower part of the processing tank 17. Therefore, when the fourth blade 26d is exposed from the garbage in the processing tank 17, the stirring efficiency of the garbage can be improved.

(B) First and second blades 26a, 26b
The angular interval therebetween is smaller than the angular interval between the second and third blades 26b and 26c. Therefore, when the garbage connected in a spiral shape is cut off, the cut garbage does not fall from between the first and second blades 26a and 26b, but between the second and third blades 26b and 26c. To fall from. Therefore,
It is possible to prevent the shredded garbage from falling into the gap formed on the rear side in the rotation direction of the first blade 26a. Therefore, it is possible to prevent the raw garbage from blocking the supply hole 20 due to the raw garbage being dropped into the gap.

(C) When all the blades 26a to 26d are filled with raw dust, when the spirally connected raw dust is cut, the cut raw garbage is separated from the first blade 26a by the first blade 26a. The second and third blades 26b, 26 located at the intermediate portion in the vertical direction between the second blade 26d and the fourth blade 26d.
It falls from both between c and on the rear side in the rotation direction of the fourth blade 26d. Therefore, in the case where all of the blades 26a to 26d are filled with the garbage in the processing tank 17,
The garbage in the processing tank 17 can be efficiently stirred.

(E) The connecting pipe 44 for exhausting the air in the processing tank 17 to the outside is rotated around the axis of the rotating pipe 46. Therefore, if the connecting pipe 44 is rotated so as to stand upright and then the inside of the connecting pipe 44 is washed with water,
It is possible to prevent the water in the connecting pipe 44 from falling into the processing tank 17 from the lid 43 side.

(F) Even if the connecting pipe 44 and the turning pipe 46 are connected in a T-shape, the turning pipe 46 is opened by removing the cap 49 from the turning pipe 46 and opening the cleaning port 46a.
Clogs and dirt inside can be easily removed.

(G) The leading end of the connecting pipe 44 is provided with the charging hole 42.
Since it is connected to the lid 43 for opening and closing, the input hole 42 can be opened and closed by the lid 43 by rotating the connecting pipe 44. Therefore, the connecting pipe 44 and the turning pipe 4
Since the air in the processing tank 17 can be exhausted and the charging hole 42 can be opened / closed by 6, the mechanism for opening / closing the lid 43 separately from the connecting pipe 44 and the turning pipe 46 is not provided. As much as possible, the configuration of the garbage processing device 11 can be simplified.

The present invention can be embodied with the following modifications, for example. (1) In the present embodiment, if the angular intervals of the blades 26a to 26d with respect to the circumferential direction of the rotary shaft 25 become non-uniform, the positions of the blades 26a to 26d are set with respect to the circumferential direction of the rotary shaft 25. You may shift it suitably.

(2) In this embodiment, the four blades 26a
Although ~ 26d is provided, the number may be three or five or more. (3) In the present embodiment, the second and third blades 26b, 2
The angular interval between the 6c and the third and fourth blades 26c, 26
Although it is larger than the angular interval of d, the angular interval of the third and fourth blades 26c and 26d may be larger than the angular interval between the second and third blades 26b and 26c.
In this case, when the garbage connected in a spiral shape is cut off, the garbage falls from between the third and fourth blades 26c and 26d to the lower portion of the processing tank 17. Therefore, also in this case, the same effect as that of the above embodiment is obtained.

(4) In this embodiment, each blade 26a
The angular interval between ~ 26d may be changed appropriately. (5) In the present embodiment, the treating agent is composed of the enzyme such as amylase, protease and lipase and the bacterium, but the treating agent may be composed of only the enzyme or only the bacterium.
Further, a treating agent may be formed by appropriately mixing a plurality of kinds of various enzymes, or the treating agent may be formed from only one of the various enzymes.

(6) In this embodiment, raw garbage is decomposed by a treating agent to be an organic fertilizer, but instead of this, raw garbage may be decomposed into feed for cultured fish, livestock and the like. Further, the garbage may be completely decomposed by the treatment agent and may be removed from the treatment tank 16.

Next, technical ideas other than the claims which can be understood from the above embodiment will be described below together with their effects. (A) A processing tank into which raw garbage is charged, an exhaust hole (injection hole 42) provided at the upper end of the processing tank for exhausting the air in the processing tank to the outside, and a tip portion of the exhaust hole.
