Description

  The present invention relates to a garbage disposal apparatus, and more particularly, to a garbage disposal apparatus for biodegrading garbage by putting the garbage, microorganisms and a moisture adjusting agent or a microorganism carrier in a treatment tank and stirring them.

  Conventionally, garbage discharged from commercial eating and drinking facilities, school lunch rooms, and households has been incinerated at incineration facilities. However, since these garbages are large and contain a large amount of moisture, harmful effects such as increasing the amount of harmful substances discharged from the incineration facility and shortening the life of the incineration facility have been pointed out. Therefore, garbage processing apparatuses that dry, decompose and process garbage at a site where the garbage is generated have come to be used.

  There are roughly two types of garbage processing equipment: dry type and decomposable type. The dry type is intended to reduce the amount of garbage by removing the water contained in the garbage, and the decomposable type is based on microorganisms. Is biodegradable. The decomposing-type garbage processing apparatus includes garbage, microorganisms, a water conditioner or a microorganism carrier (hereinafter sometimes simply referred to as “stirred matter”) and oxygen necessary for the survival and oxidative decomposition of microorganisms in the treatment tank. And the stirring blade provided in the treatment tank is rotated to stir the object to be stirred to promote the decomposition of the garbage.

  However, since the conventional garbage processing apparatus cannot supply a sufficient amount of oxygen to the agitated material, the oxidative decomposition of garbage due to oxygen respiration by microorganisms is not sufficiently promoted, and further, the odor of spoilage There was a problem of generating.

  Therefore, a rotating shaft is provided in the vertical direction at the center in the treatment tank, and a through cylinder having an opening at the top and bottom is fixed to the rotation shaft at the center of the treatment tank, and a stirring blade is provided on the rotation shaft. A fixed garbage disposal device has been proposed (see, for example, Patent Document 1). This garbage disposal apparatus supplies air (oxygen) taken from the upper opening of the through-cylinder to the stirred object outside the through-cylinder through the lower opening of the through-cylinder that opens in the lower layer of the accumulated stirred object. It was a device that promotes the decomposition of garbage by microorganisms.

  However, in the above garbage disposal apparatus, a phenomenon occurs in which an agitated object enters the inside of the through-cylinder from the lower opening of the through-cylinder and blocks the lower opening of the through-cylinder as the stirring blade and the through-cylinder rotate. In this case, the amount of oxygen supply can be increased as compared with a conventional garbage processing apparatus not provided with a through-cylinder, but fresh oxygen is supplied from the lower opening to the stirred object outside the through-cylinder. The problem of not being able to supply sufficiently, the oxidative decomposition of garbage due to oxygen respiration of microorganisms not being sufficiently promoted, and further generating a rotten odor has not been sufficiently solved.

  Therefore, the present invention solves the above-mentioned problems of the prior art, and supplies a sufficient amount of oxygen to the object to be stirred and the microorganism to promote oxidative decomposition of the garbage due to oxygen respiration of the microorganism, thereby treating the garbage.

  The present invention will be described with reference to the drawings. As shown in FIG. 1, the garbage processing apparatus 1 includes a processing tank 2, a rotating shaft 3 disposed vertically in the center of the processing tank 2, a passing cylinder 4, and a stirring blade 5. It is good also as a structure provided with the fixed blade 7 and the crushing blades 61 and 62. FIG.

  The treatment tank 2 is a tank for agitating the agitated object 100 composed of garbage, microorganisms and a moisture adjusting agent or a microorganism carrier in the treatment tank 2 to treat the garbage, and the upper and lower ends are sealed. The cylindrical shape is formed using a material that is not easily corroded, such as stainless steel.

  The upper plate 21 that closes the upper end of the processing tank 2 is provided with an air supply port 12 and a tank exhaust port (not shown), and an air supply fan 11 that sends air into the processing tank 2 is installed on the upper surface of the upper plate 21. The air outlet 111 of the fan 11 is inserted into the air supply port 12, and the air outside the processing tank 2 containing oxygen is sent from the air supply port 12 into the processing tank 2 by the air supply fan 11. In addition, the air in the treatment tank 2 moves from the tank exhaust port to a deodorizer (not shown), passes through a dust-proof filter installed in the deodorizer and a filter containing an adsorbent such as zeolite, and is discharged from the garbage treatment apparatus 1 from the exhaust port. Is discharged. The opening of the tank exhaust outlet can be adjusted or cannot be adjusted, and the size of the tank exhaust outlet is set to at least the size of the air supply port 12. Further, by adjusting the amount of air supplied by the air supply fan 11 and installing a deodorizer, the air pressure in the treatment tank 2 can be maintained at a positive pressure, and air can be supplied from the surface of the object to be stirred 100. Permeated to the inside, oxygen can be sufficiently supplied to the microorganism, and oxidative degradation due to oxygen respiration of the microorganism is promoted. If the negative pressure is used, the air supply fan is easily rusted by hydrogen sulfide and its life is short. However, if the positive pressure is used, the influence of hydrogen sulfide is small, the life is long, and it is economical.

  Although not shown, the upper plate 21 of the processing tank 2 is provided with a charging port for garbage or the like, and can be opened and closed by a pivotally supported lid. In order to prevent the material to be stirred 100 from being introduced into the through-cylinder 4, the introduction port is provided so as to avoid being directly above the through-cylinder 4. Further, an extraction port for the object to be stirred 100 is provided in the middle part and / or lower part of the treatment tank 2 and can be opened and closed by a pivotally supported lid. Since a transmission or the like is placed on the upper plate 21 of the processing tank 2, a reinforcing beam 144 is provided on the upper surface of the upper plate 21.

  In the center of the processing tank 2, a rotating shaft 3 perpendicular to the bottom surface 23 of the processing tank 2 is provided. The rotating shaft 3 is pivotally supported by a bearing 91 provided at the bottom 22 of the processing tank 2 and a bearing 92 provided at the top of the processing tank 2. The rotating shaft 3 passes through a through-hole 211 provided in the upper plate 21 of the processing tank 2, and a clearance between the through-hole 211 and the rotating shaft 3 is sealed by a sealing member (not shown) so that the airtightness of the processing tank 2 is achieved. Is secured. Although not shown, in the storage box 90 installed on the upper plate 21 of the processing tank 2, the upper end of the rotary shaft 3 is connected to the shaft of the transmission by chain coupling, and the transmission is further connected to the power source. The rotating shaft 3 rotates with the rotation of the motor. Further, on the upper plate 21 of the processing tank 2, an operation panel including an operation switch such as a control device, a motor and an air supply fan 11 is provided.

  The through-cylinder 4 is a member for supplying air, particularly oxygen, to the object to be stirred 100, and depending on its shape, is a member that acts to stir the object to be stirred 100. As shown, the upper and lower portions are open, and the cross-sectional shape in which the vertical through-hole 40 is formed on the side wall 41 is a square cylindrical body. And the opening part of the upper end of the through-hole 40 and the opening part of a lower end become the upper end opening 42 and the lower end opening 44, respectively, and the air sent via the air supply fan 11 in the processing tank 2 passes through the cylinder from the upper end opening 42. 4 flows into the cylinder 4, flows out of the through-cylinder 4 from the lower end opening 44, and is supplied to the stirring object 100.

  In the through-cylinder 4, the rotary shaft 3 positioned at the center of the through-cylinder 4 passes through the through hole 40 in the vertical direction. Specifically, the rotary shaft 3 passes through the through-cylinder 4 and protrudes from the upper end opening 42 and the lower end opening 44. The rotating shaft 3 is fixed to the stirring blade 5 protruding in the direction of the side wall 27 of the processing tank 2, is fixed to the rotating shaft 3, and is installed at the center of the processing tank 2.

  With this configuration, the through cylinder 4 rotates in the same direction as the rotation shaft 3 rotates. The movement of the object to be stirred 100 from the upper end opening 42 of the through-cylinder 4 to the inside of the through-cylinder 4 closes the lower end opening 44 or the through-hole 40 of the through-cylinder 4 and causes air from the lower end opening 44 of the through-cylinder 4 to flow. Since it is not desirable to prevent the outflow, the upper end of the through-cylinder 4 is preferably located at a position higher than the agitated object 100 put into the treatment tank 2, and the agitated object 100 accumulated in the treatment tank 2. It is desirable that the lower end of the through-cylinder 4 is as close as possible to the bottom surface 23 of the processing tank 2 so that oxygen can be supplied to the deep part. Therefore, it is preferable to install the through cylinder 4 with such a height that the upper end thereof is positioned in the vicinity of the upper end of the processing tank 2 and the lower end thereof is positioned in the vicinity of the lower end of the processing tank 2. In this way, the air enters and exits the inside of the through-cylinder 4, but the object to be stirred 100 does not enter from the upper end opening 42.

  The cross-sectional shape of the through-cylinder 4 is preferably a square shape with good stirring efficiency and less burden on the motor as in the embodiment illustrated in FIGS. 1 to 5, but is not limited to this shape. 6 (e)), a polygon such as a rectangle, a pentagon, a star, or the like, and an agitated shape capable of stirring the object to be stirred 100 is also possible. In addition, although the stirring function is lowered, the cross section can be circular (FIG. 6D), oval, or the like. Furthermore, in order to increase the stirring efficiency, the through-cylinder 4 may be installed by removing the eccentricity of the rotary shaft 3 from the center of the cylinder 4.

  The stirring blade 5 is a member for stirring the object to be stirred 100 in the processing layer 2, one end is fixed to the rotating shaft 3, the direction of the side wall 27 of the processing tank 2 and the direction orthogonal to the rotating shaft 3, That is, it extends in the horizontal direction. The stirring blade 5 is provided with a plurality of stages of two or more stages according to the height (depth) of the processing layer 2 by changing the position in the vertical direction. A predetermined number is provided radially from 3. As a specific example, as shown in FIGS. 1 and 2, the stirring blade 5 has four stages, and two stirring blades 5 are provided in the opposite direction across the rotation shaft 3 from the same height of the rotation shaft 3. Each stage can be installed with a 90 ° shift in the rotational direction of the rotary shaft 3.

  The shape of the stirring blade 5 is not particularly limited, and a flat plate, a rod-like body, or the like can be used. However, in order to increase the strength of the stirring blade 5, it is preferably configured using an angle with an L-shaped vertical section. In addition, since a stronger pressure is applied to the portion from the fixed position with the rotary shaft 3 to the fixed position with the through-cylinder 4, in order to further increase the strength of the stirring blade 5, as shown well in FIG. 4 and FIG. It is preferable that the part from the fixed part with the rotating shaft 3 of the stirring blade 5 to the fixed part with the through-cylinder 4 is configured in a box shape by alternately fixing the angles 59 having the L-shaped longitudinal section.

  When an angle 59 having an L-shaped vertical cross section is used as the stirring blade 5, the horizontal piece 501 can be horizontal and the vertical piece 502 can be erected upward from the rear end in the rotational direction of the horizontal piece 501. And by setting it as such a structure, it becomes easy to move the to-be-stirred object 100 by the vertical piece 502 by rotation of the stirring blade 5, and it becomes possible to raise stirring efficiency.

  Two stirring blades 51 provided at the lowermost stage are provided in parallel with the bottom surface 23 of the processing tank 2 so as to have an angle of 180 ° around the rotation shaft 3. As shown in FIGS. 1, 4, and 5, the upper end of the stirring blade 51 is in contact with the lower end of the passing cylinder 4, and the passing cylinder 4 is placed on the stirring blade 51, and the second to fourth stages of stirring are performed. The blades 5 are fitted into and penetrate through side holes 49 formed in the side wall 41 of the through-cylinder 4, and are fixed by welding. Accordingly, a part of the through hole 40 of the through cylinder 4, here the lower end opening 44, is blocked by the stirring blade 51. The agitation blade 51 may be configured to block a part of the lower end opening 44 while penetrating the lower end portion of the side wall 41 of the passage cylinder 4 instead of the upper end of the agitation blade 51 being in contact with the lower end of the passage cylinder 4.

  Then, a lid 47 that closes a part of the lower end opening 44 at the front portion in the rotational direction of the stirring blade 51 is extended from the stirring blade 51, and a part of the lower end opening 44 is left open. Is closed with a lid 47. Specifically, as shown well in FIGS. 4, 5, and 6 (a), from the upper surface of the stirring blade 51, the front portion of the lower end opening 44 in the rotational direction of the stirring blade 51 is changed from the stirring blade 51 to the stirring blade 51. The front portion of 90 ° in the rotation direction is closed with a substantially rectangular lid body 47. The lid body 47 extends from the entire width of the front end in the rotational direction of the stirring blade 51 in the cylinder 4, and one end portion of the lid body 47 is mounted on the upper surface of the horizontal piece 501 of the angle 59 constituting the stirring blade 51. Only one side of the lid 47 faces the lower end opening 44, and the other two sides are fixed in contact with the through-cylinder 4. Then, around the rotation shaft 3, the portions closed by the lid body 47 and the openings 441 are alternately arranged. In addition, the rotation direction of the rotating shaft 3, the cylinder 4 and the stirring blade 5 is indicated by an arrow G in the figure.

  With such a configuration, the object to be stirred 100 that is about to move upward by the pressure of the rotating stirring blade 51 enters the inside of the through-cylinder 4 from the lower end opening 44, closes the lower end opening 44, and To prevent the air from passing through the upper end opening 42 from being sent to the lower layer of the object to be stirred 100 outside the cylinder 4, so that sufficient air is supplied to the lower layer of the object to be stirred 100 through the cylinder 4. And oxygen can be sent.

  The amount of the front portion in the rotational direction of the stirring blade 51 of the lower end opening 44 closed by the lid 47 is not particularly limited as long as the opening 441 is configured without blocking the entire lower end opening 44, In order to reliably prevent the object 100 from entering the inside of the through-cylinder 4 and at the same time reliably send sufficient air and oxygen to the lower layer of the object to be stirred 100, about 40 to 60% of the lower end opening 44 is an area. More preferably, it is 50%, and if it shows by the angle to the rotation direction of the stirring blade 5, it is preferable to block the front part of about 45-120 degrees from the stirring blade 51, and 90 degrees is more preferable.

  The lid 47 is configured by installing a flat plate horizontally with the bottom surface 23 of the processing tank 2, but is configured by inclining the flat plate upward toward the front of the stirring blade 51 in the rotational direction, or forward in the rotational direction. You may comprise by the board provided with the part which curves and bends upwards toward the upper side. Further, the lid body 47 is not limited to a plate body, and an arbitrary shape such as a block body can be used.

  Further, one end of the lid 47 may be placed on the upper surface of the stirring blade 51, or a structure fixed to the side surface of the stirring blade 51 may be used. Further, only one side of the lid 47 faces the lower end opening 44, and the other side is not limited to the configuration fixed in contact with the stirring blade 51 or the cylinder 4 and, as will be described later, A configuration in which the side faces the lower end opening 44 can also be adopted.

  As shown in FIG. 1, a plurality of square pillar-shaped grinding blades 61 projecting downward are provided at predetermined intervals on the lower end of the stirring blade 51, that is, the back surface 511 of the horizontal piece 510. The stirring blade 51 is fixed at a position close to the bottom surface 23 so that the lower end of the grinding blade 61 does not contact the bottom surface 23 of the processing tank 2.

  On the other hand, as shown in FIGS. 1 and 2, the bottom surface 23 of the processing tank 2 is provided with a plurality of square pillar-shaped crushing blades 62, 62... Protruding upward from the center of the bottom surface 23 of the processing tank 2. It is fixed radially in 24 directions, and 6 rows are provided at intervals of 60 °. The crushing blades 62, 62... For each row are fixed at equal intervals, and this interval is the same as the interval between the crushing blades 61, 61. The crushing blades 62, 62... And the crushing blades 61, 61... Are fixed on different circumferences around the rotation shaft 3, and the crushing blades 61, 61. Since it passes along a circular orbit, the space between the grinding blades 62, 62... And the space between the grinding blades 61, 61. If the crushing blades 62, 62... And the crushing blades 61, 61... Are fixed on different circumferences centering on the rotation shaft 3, the installation positions can be changed without being arranged in rows or at equal intervals. Is possible.

  A fixed number of fixed blades 7 that are positioned between the stirring blades 5 provided in a plurality of stages and extend horizontally in the direction of the rotation shaft 3 are fixed to the inner side surface 24 of the processing tank 2 in a side view. That is, the fixed blade 7 is installed such that the inclination angle with respect to the bottom surface 23 is the same as the inclination angle of the stirring blade 5. Further, the fixed blade 7 corresponds to the stirring blade 5 and is installed in parallel with the stirring blade 5 and in sliding contact with a predetermined interval. The fixed blade 7 is a member for sandwiching and crushing garbage between the fixed blade 7 and the stirring blade 5. The shape of the fixed blade 7 is not particularly limited, and a flat plate, a rod-like body, or the like can be used. However, in order to increase the strength, it is preferable that the fixed blade 7 is configured using an angle with an L-shaped vertical section.

  In the embodiment shown in the drawing, the fixed blade 7 is provided in three stages, and the first stage in the lowermost stage is provided with three fixed blades 7 at intervals of 120 ° around the rotation shaft 3, and the second stage is rotated. Two fixed blades 7 are provided at an interval of 180 ° centering on the shaft 3, and three fixed blades 7 are provided at an interval of 120 ° around the rotation shaft 3 in the third uppermost stage. However, the number of installation of the fixed blade 7, the installation interval, and the number of installation stages are not particularly limited, and the number of installations at the same height may be one, or a plurality. When the fixed blade 7 is provided in a plurality of stages at different heights, the number of installations and the installation position may be the same for each stage, but may be different.

  The stirring blade 5 is buried in the object to be stirred 100 and is easily bent or distorted downward by being pressed downward by the weight pressure of the object to be stirred 100. Therefore, although not shown, a support protrusion is provided so as to protrude from the inner surface 24 in the direction of the rotation axis 3 in parallel with the bottom surface 23 over the entire circumference of the inner surface 24 of the treatment tank 2, and the tip of the stirring blade 5 is provided. It is preferable to prevent the bending and distortion of the stirring blade 5 by placing and supporting. In addition, it is good also as a structure which supports only the stirring blade 5 of the predetermined | prescribed step, for example, the lowermost stirring blade 51, not supporting the stirring blade 5 of all the steps by a support protrusion.

  Next, the use and operation of the garbage disposal apparatus 1 will be described. First, a water-adjusting material such as one obtained by finely cutting newspaper, sawdust, or the like, microorganisms containing fungi, and garbage are fed into the treatment tank 2 excluding the inside of the through-cylinder 4. At this time, only the amount of the object to be stirred 100 that does not reach the upper end of the through-cylinder 4 is charged. Next, the operation panel is operated to obtain electric power from a power source (not shown) and operate a motor as a power source to rotate the rotating shaft 3 through the transmission, thereby rotating the cylinder 4 and the stirring blade 5. At the same time, the air supply fan 11 is operated to send air into the treatment tank 2.

  Wind speed resistance is generated by adjusting the opening of the tank exhaust outlet, etc., and the amount of air sent into the processing tank 2 is increased from the air discharged from the processing tank 2 to maintain the inside of the processing tank 2 in a positive pressure state. As a result, the air in the treatment tank 2 penetrates from the upper surface of the object to be stirred 100 to the inside, passes through the cylinder 4 from the upper end opening 42, and passes through the lower end opening 44 from the deep part of the object to be stirred 100 to the inside. To sufficiently supply oxygen to the object to be stirred 100.

  The object to be stirred 100 is pushed upward by the vertical piece 502 of the stirring blade 5, moved from the center of the treatment tank 2 toward the inner side surface 24 by the centrifugal force of the stirring blade 5, hits the inner side surface 24, and moved upward, It collapses and collides with the through-cylinder 4, and it is repeatedly stirred at the corner of the through-cylinder 4 and sent out in the direction of the inner surface 24. The agitated object 100 does not enter the through cylinder 4 even during agitation. In this way, the garbage and microorganisms are efficiently stirred, and the treatment tank 2 has a positive pressure, so that oxygen is sufficiently supplied from the cylinder 4 to the stirred object 100 and is oxidatively decomposed by the garbage-decomposing microorganisms. Is promoted. Usually, the stirring blade 5 is rotated and stopped repeatedly at a predetermined interval, but it is desirable to blow air into the treatment tank 2 even when the stirring blade 5 is stopped.

  It should be noted that hard and soft solids such as bones, shells, and chopsticks in the garbage during agitation are engaged with the crushing blades 61, 61... Further, by being sandwiched between them, it is further pulverized by being sandwiched between the tip of the horizontal piece 501 of the stirring blade 5 and the fixed blade 7. In addition, the air in the treatment tank 2 moves from the tank exhaust outlet to the deodorizer, passes through a dust-proof filter installed in the deodorizer and an adsorbent-containing filter such as zeolite, and is deodorized and collected. Dust air is discharged out of the garbage disposal apparatus 1 from the exhaust port.

  A form other than the above can also be adopted as an embodiment of the stirring blade. For example, instead of being provided in the horizontal direction, the angle relative to the bottom surface 23 of the processing tank 2 may be changed by extending obliquely upward from the rotating shaft 3 or extending obliquely downward. In such a case, the fixed blade has the same inclination angle with respect to the bottom surface 23 as the inclination angle of the stirring blade.

  One or three or more stirring blades may be extended from the same height of the rotary shaft 3. Further, when a plurality of stirring blades are provided from the same height of the rotating shaft 3, they may be provided at the same interval or at different intervals. Further, when a plurality of stirring blades are provided, the stirring blades may be configured not to be shifted in the rotation direction of the rotating shaft 3 for each step, or may be configured to be shifted at an angle other than 90 °. Further, when a plurality of stages are provided, the number of installations may be different for each stage.
