[0005]

In the waste decomposition apparatus 100, the amount of the organic waste M adhering to the stirring blades 55 increases as the stirring and fermentation progresses, or the stirrer 56 advances. Organic waste M in the rear and lower directions
However, there is a problem that the efficiency of the stirring is reduced due to the useless drive resistance caused by stirring. That is, the organic waste M processed by the present apparatus 100 contains water and easily adheres to the stirring blade 55. However, when the amount of adhesion increases, the amount of the organic waste M stirred by the stirring blade 55 decreases. Therefore, the stirring amount is reduced with respect to the driving amount of the stirrer 56. However, an enormous amount of labor is required for the operation of removing the organic waste M attached to each stirring blade 55, and thus effective measures have been required. The purpose of the stirrer 56 of the present apparatus 100 is to stir the organic waste M on the front side in the traveling direction. Since the object M is also agitated and the useless drive resistance increases, the efficiency of the agitation is reduced and the agitation takes time. In addition, in response to the increase in the driving resistance, the strength of the stirrer 56 and the structure supporting the stirrer 56 is improved, and the traveling motor 52 and the stirring motor 5 are used.
Since the output of the device 7 needs to be increased, there is also a problem that the entire device 100 becomes large.

[0006] The present invention has been made in view of the above circumstances, and by reducing the driving resistance of the stirrer 56, the efficiency of stirring and fermentation of the organic waste M is improved, and the whole is reduced in size. It is an object of the present invention to provide a waste decomposition treatment apparatus that can be converted into a waste.

This is the solution to the problem.

According to the present invention, the organic waste in the storage tank is scraped by the flight member moved forward in the traveling direction of the stirrer with the rotation of the endless winding body, thereby promoting the stirring fermentation. The flight member moves with the rotation of the endless winding body, and is cleaned by a cleaning mechanism at a place other than the front side in the traveling direction, and the attached organic waste is peeled off. Thus, the efficiency of scraping the organic waste by the flight member can be maintained.

According to the second aspect of the present invention, the flight member is rotatably provided with an axis (16) parallel to the rotation axis of the endless winding body, and scrapes the organic waste when protruding outside the endless winding body. It has a stirring blade (17) to be fried, and a contact member (19) fixed at an angle to the stirring blade, and the flight is performed on the front side in the traveling direction of the stirrer when the endless winding body is rotationally driven. When the abutment member abuts and rotates on the projecting scraper (18) disposed on the inner side of the movement locus of the rotation axis of the member, the stirring blade protrudes outward due to rotation, and the flight member is located at a location other than the front side in the advancing direction of the agitator. The agitating blade abuts against a pushing scraper (21) disposed outside the movement locus of the rotation axis of the agitating blade, and the agitating blade is rotated so that the agitating blade is pushed inward. Body rotation Thus waste decomposition treating apparatus according to claim 1, characterized in that it is installed in the vicinity of the movement locus of the flight members to move rearward from the traveling direction front side of the agitator was set to solutions of the problems.

According to the present invention, the flight member, which has moved to the front in the advancing direction of the stirrer with the rotation of the endless winding body, is rotated by the contact between the contact member and the projecting scraper. Protrudes outward, and the organic waste can be stirred. At this time, the contact member is substantially parallel to the movement trajectory of the flight member. The flight member that has passed the front side in the traveling direction of the stirrer is rotated by the contact between the stirring blade and the pushing scraper, and the stirring blade is pushed into the movement trajectory side of the flight member and becomes substantially parallel to the endless winding body. As a result, the stirrer does not stir the organic waste existing around the stirrer except for the front side in the traveling direction, and wasteful contact resistance is reduced. At this time, when the front surface in the moving direction of the stirring blade comes into contact with the pushing scraper, the organic waste adhered to the stirring blade by the pushing scraper is stripped off, and further removed by the cleaning mechanism. The cleaning mechanism is preferably installed at a position where the flight member does not come into contact with the organic waste, in the middle of entering the rear side from the front side in the traveling direction of the stirrer or in the rear side in the traveling direction,
More preferably, not only the stirring blade of the flight member but also the entire outside of the endlessly wound body is cleaned. By cleaning the outside of the endlessly wrapped body, it is possible to reduce the contact resistance with the organic waste in places other than the front side in the traveling direction of the stirrer. The contact member protrudes inward from the movement locus of the rotation axis of the flight member at the same time that the stirring blade is pushed in. When the flight member reaches the vicinity of the projecting scraper, the contact member comes into contact with the projecting scraper.

The boundary between the connection plates 12 that are continuously attached corresponds to the pin-connected portion of the chain 8 that bends when bent. Since the pin connecting portions of the chain 8 are aligned with the left and right chains 8, when the chain 8 passes through the sprockets 6, 7, the connecting plates 12 are also relatively displaced in accordance with the bending of the chains 8. I have. In addition, between the connection plates 12 that are continuously attached,
It suffices if there is a gap that allows relative displacement between the connecting plates 12, and the connecting plates 12 are close to each other so as to be almost in contact with each other.

The flange on the other side of the flight member 10 is parallel to the chain 8 or directed inside the chain 8, and when the chain 8 is driven to rotate, on the front side in the traveling direction of the agitator 5, inside the movement locus of the shaft 9 of the flight member 10. The agitating blade 17 functions as an abutting member 19 that abuts on the disposed scraping scraper 18 to protrude outward. The stirring blade 17 and the abutting member 19 are formed to have the same dimensions, and both can be made to appear and retract on the same plane as the connecting plate 12 by the rotation of the flight member 10. The stirring blade 17 and the contact member 19 are
When it is parallel to the connecting plate 12, it is formed to have a size that substantially closes the mounting area 10a of the flight member 10.

As shown in FIGS. 2 and 3, the projecting scraper 18 is a sled-shaped plate member, and is disposed along each chain 8 on the front side in the traveling direction of the stirrer 5. The projecting scraper 18 is connected to the upper and lower drive shafts 11.
The stirrer 5 has a length extending over the space, and is arranged so as to be in the vicinity of the movement trajectory of the flight member 10 passing the front side in the traveling direction of the stirrer 5. Projecting scraper 18
2 and 4, is disposed near the lower sprocket 7, and the rotation of the chain 8 drives the flight 10 entering the front from the rear in the advancing direction of the stirrer 5 in the advancing direction. The flight member 10 is rotated clockwise in the figure in contact with the contact member 19 of FIG. Projecting scraper 1
8 is arranged near the movement trajectory of the flight member 10, the contact member 19 abutting on the distal end portion 20 of the projecting scraper 18 is flush with the connecting plate 12, and furthermore, the traveling direction of the stirrer 5. The abutting member 19 and the projecting scraper 18 are always in sliding contact with each other while passing through the front side, so that the flight member 10 is prevented from rotating counterclockwise, and the stirring blade 17 is maintained in the projected state. .

As shown in FIGS. 1 and 5, in the vicinity of the upper sprocket 6, a pushing scraper 21 is disposed. The pushing scraper 21 is disposed outside the movement locus of the shaft 9 of the flight member 10 and
The flight member 10 which enters in the state of protruding outward from the front side to the rear side in the traveling direction of the stirrer 5 by the rotational drive of the stirrer 5.
Agitating blade 17 is rotated in a counterclockwise direction in the figure (arrow in FIG. 5) so that stirring member 17 is rotated inward of agitator 5 so as to be parallel to chain 8. Performs the pushing function. The stirring blade 17 of the rotated flight member 10 is flush with the connecting plate 12, and the contact member 19 projects inside the stirrer 5.

In the vicinity of the pushing scraper 21, a brush (cleaning mechanism) 24 in the form of an external roll for peeling off the organic waste M adhered to the stirring blade 17 is provided. The brush 24 is rotatably supported by an axis parallel to the sprocket 6, and is rotatably driven by a drive mechanism (not shown). Further, the outer peripheral portion of the brush 24 reaches the outer surface of the connecting plate 12, so that not only the stirring blade 17 but also the organic waste M adhered to the connecting plate 12 is peeled off when the brush 24 is driven to rotate. Has become. In addition, the brush 24 is generally rotated counterclockwise in FIGS. 1 and 2, whereby the peeled organic waste M is blown to the rear of the stirrer 5, and 5 are deposited together with the organic waste M which has been fried. Further, in the organic waste M blown off by the brush 24, the bridge between the particles of the organic waste M is cut, so that the stirring fermentation is promoted. In the present embodiment, the attachment position of the brush 24 is on the rear side of the pushing scraper 21 in the rotation direction of the chain 8, but may be on the front side of the rotation direction of the chain 8.

The operation and effect of the present invention will be described below. The waste decomposition apparatus 1 according to the present invention is stored in the storage tank 2 by driving the traveling body 4 and moving the stirrer 5 while rotating the chain 8 clockwise in FIGS. 1 and 2. The organic wastes M are sequentially stirred and fermented.
When the chain 8 is rotationally driven, the flight member 10 entering the front side from the rear side in the traveling direction of the stirrer 5 near the lower sprocket 7, the contact member 10 directed toward the inside of the stirrer 5 is moved. Tip 20 of projecting scraper 18
Is rotated clockwise by contact with the contact member 1
0 is flush with the connecting plate 12 and the stirring blade 17
Are projected outward.

When the flight member 10 moves forward in the advancing direction of the stirrer 5 in accordance with the rotation of the chain 8, the contact member 19 moves the projecting scraper 18 until the flight member 10 reaches the vicinity of the upper sprocket 6. And the flight member 10 is prevented from rotating counterclockwise, so that the protruding state of the stirring blade 17 is maintained against the contact resistance with the organic waste M. The waste M is scraped up. At this time, the attachment area 10a of the flight member 10 is closed by the contact member 19, so that the organic waste M is prevented from entering the inside of the stirrer 5.

The flight member 10 that has passed the front side in the traveling direction of the stirrer 5 reaches the brush 24 that is driven to rotate, and the attached organic waste M is removed and cleaned. The cleaning by the brush 24 is mainly performed on the surface that becomes the outer surface side after the abutment of the stirring blade 17 with the pushing scraper 21, but the connection plate 12 is sufficiently cleaned. The flight member 10 is further moved to keep the stirring blade 1
7 comes into contact with the pushing scraper 21. Thereby, the flight member 10 rotates counterclockwise, the contact member 19 is directed toward the inside of the stirrer 5, and the stirring blade 17 is connected to the connecting plate 12.
It is pushed so that it may become flush. At this time, by placing the pushing scraper 21 at a position where it comes into contact with the base end of the stirring blade 17, the organic waste adhered to the stirring blade 17 when the stirring blade 17 comes into contact with the pushing scraper 21. M can be peeled off by the pushing scraper 21. Therefore, the organic waste M adhered to the stirring blade 17 is reliably removed by the brush 24 and the pushing scraper 21. Since the flight members 10 connected to the chain 8 sequentially come into contact with the brush 24 and the pushing scraper 21 as the chain 8 rotates, the removal of the organic waste M from all the flight members 10 is performed automatically. Elimination of the need for a separate removal operation. Further, the organic waste M attached to the outer surface of all the connecting plates 12 can be removed by the brush 24.

As a result, on the rear side in the traveling direction of the stirrer 5,
Since the parts of the flight member 10 protruding outward by the pushing of the stirring blade 17 are eliminated, and the mounting area 10a of the flight member 10 is closed by the stirring blade 17, contact with the organic waste M around the stirrer 5 is prevented. The resistance drops significantly. At this time, the outer surface of the stirring blade 17 facing the organic waste M is sufficiently cleaned by the brush 24 and the pushing scraper 21, and the organic waste M of the connecting plate 12 is removed.
Is sufficiently cleaned by the brush 24, so that the stirring blade 17 and the connecting plate 12 can move smoothly with respect to the organic waste M, and the contact resistance can be greatly reduced. On the other hand, the removal of the deposits on the stirring blade 17 by cleaning can maintain the amount of the organic waste M scooped by the stirring blade 17 on the front side in the traveling direction of the stirrer 5, and The efficiency of stirring fermentation of the whole organic waste M is improved. Further, the contact member 19
Until the blade contacts the projecting scraper 18 again.
Since the protrusions 7 do not protrude outward, the contact resistance of the stirrer 5 with the organic waste M can be significantly reduced even at the lower portion of the stirrer 5. As described above, since the driving force of the stirrer 5 is used only for scraping and agitating the organic waste M on the front side in the traveling direction, the drive mechanism of the stirrer 5 is reduced in size and acts on the stirrer 5 during the stirring operation. The support structure for supporting the reaction force can be simplified, and the waste decomposition apparatus 1 can be reduced in size and cost.

As shown in FIG. 7, the stirrer 5 includes:
It is also possible to install a pressure receiving plate 22 that converts the load of the organic waste M that has been lifted and conveyed into the forward direction of the stirrer 5 on the rear side in the traveling direction. In this case, the upper end portion 23 of the pressure receiving plate 22 installed near the sprocket 6 above the stirrer 5 functions as the pushing scraper 21. By doing so, all of the organic waste M removed from the stirring blade 17 in contact with the upper end portion 23 of the pressure receiving plate 22 falls on the pressure receiving plate 22,
As the pressure receiving plate 22 moves along with the advance of the stirrer 5, it gradually falls to the lower part of the storage tank 2, so that it is possible to prevent solidification due to rapid accumulation of the organic waste M after stirring, The efficiency of stirring fermentation can be improved. When the brush 24 rotates counterclockwise, the organic waste M that is removed from the flight member 10 and the like by the brush 24 is also dropped and deposited on the pressure receiving plate 22. Since all the organic wastes M scraped on the front side fall on the pressure receiving plate 22 and the falling position after the scraping is stabilized, the stirred fermentation can be efficiently promoted in a planned manner.

A contact member 19 for the stirring blade 17
Is not limited to vertical. Further, the shape of the flight member 10 is not limited to the illustrated one. For example, the abutting member may have a protruding shape other than the flange shape as long as the abutting member can abut on the projecting scraper 18.
The endless winding body is not limited to the chain 8, and a belt or the like can be applied. The cleaning mechanism is not limited to the brush 24 described in the present embodiment. For example, a mechanism that removes the organic waste M from the outside of the endless winding body by reciprocating motion may be applied.

A cleaning mechanism for removing the organic waste attached to the flight member that scoops up the organic waste at the front side in the traveling direction of the stirrer is installed, and the organic waste attached to the flight member is removed at a location other than the front side in the traveling direction. Since the cleaning mechanism is used to peel off and clean, it is possible to prevent a reduction in the amount of organic waste scraped up by flight members, and to improve the efficiency of stirred fermentation of the entire organic waste in the storage tank. It has the effect.

According to the second aspect of the present invention, the stirring blade of the flight member, which has passed the front side in the advancing direction of the stirrer, is rotated by contact with the pushing scraper by the rotation drive of the chain, and the stirring is performed.

Since the contact resistance with the organic waste existing around the stirrer is reduced except in the forward direction, the stirring resistance of the stirrer is reduced, and the drive mechanism of the stirrer is downsized and the support structure of the stirrer is simplified. Makes it easy to reduce the size and cost of the entire device, and the organic waste adhering to the stirring blades is peeled off by the pushing scraper and the cleaning mechanism.
Since organic waste can be automatically removed from all stirring blades, the efficiency of stirring and fermentation of organic waste by the stirrer is further improved, and special work for removing attached organic waste is not required, and maintenance is performed. Etc. also become easy. In addition, the removal of the attached waste on the outer surface after the contact of the stirring blade with the pushing scraper reduces unnecessary contact resistance with organic waste existing around the stirrer except for the front side in the traveling direction. It has an excellent effect of greatly reducing the efficiency of stirring the organic waste by the stirrer.

According to the third aspect of the present invention, the cleaning mechanism is a brush that is rotationally driven with a rotation axis parallel to the rotation axis of the endless winding body, and is attached to the flight member by rotating the brush.
