[0003]

Although the stirring blade of the conventional garbage disposal has a blade attached to the rotating shaft, it is not always high in stirring efficiency of the garbage in the tank. It wasn't. For example, when a uniaxial screw type stirring blade is used, all the garbage in the processing tank is sent in the direction opposite to the screw advancing direction of the screw blade and pressed against the inner wall of the processing tank. As a result, the raw dust locally accumulates in the portion along the inner wall of the processing tank, which lowers the efficiency of stirring the raw dust.

It is an object of the present invention to provide a garbage treating machine having a stirring blade capable of sufficiently stirring the garbage in the processing tank.

[0005]

SUMMARY OF THE INVENTION A raw garbage processing machine of the present invention has a raw garbage processing tank having an input port for raw garbage at the top and a discharge port for processed materials at the bottom, and the raw garbage processing tank. An agitating blade provided therein, the agitating blade being provided substantially horizontally in the garbage disposal tank, and the agitating blade being provided on the agitating shaft at a distance in a longitudinal direction of the agitating shaft. In the garbage disposal provided with the blades, the blades on both ends in the longitudinal direction of the rotary shaft are all oriented so that the garbage is drawn toward the center of the rotary shaft in the longitudinal direction. It is a thing.

When this stirring blade is rotated, the raw garbage (and the processing medium) in the treatment tank is attracted toward the center of the treatment tank, so that the whole raw garbage in the treatment tank is sufficiently agitated. .

In the present invention, the blades on both longitudinal ends of the rotary shaft have a triangular or trapezoidal side view shape which narrows toward the longitudinal center of the rotary shaft. Also, on the center side, there is provided a plate-like blade that scrapes raw garbage toward the discharge port when the rotation shaft rotates in the reverse direction and scraps raw garbage in the opposite direction when the rotation shaft rotates in the normal direction. Is preferred.

In such a structure, when the rotary shaft is rotated in the opposite direction, all the garbage in the processing tank can be strongly attracted toward the discharge port, and the processed garbage can be quickly discharged from the discharge port. Can be discharged. When the rotating shaft is rotated in the forward direction, the garbage is squeezed toward the center on both sides of the rotating shaft, but in the center side of that, a force in the opposite direction acts on at least some of the garbage. Come to do. As a result, the garbage in the treatment tank is sometimes subjected to a force in the direction toward the discharge port, and in some cases a force in the direction away from the discharge port, so that the garbage is stirred extremely strongly. Become.

In the present invention, it is preferable that the stirring blade is provided with a triangular or trapezoidal side view shaped blade that narrows toward the discharge port, closer to the center than the blades on both ends.

With this arrangement, when the rotary shaft is rotated in the forward direction, the raw dust in the processing tank can be extremely strongly attracted toward the discharge port, and the treated raw dust (decomposition) is decomposed. Can be discharged very quickly from the discharge port.

According to the present invention, by mounting the blade on the non-circular portion of the rotary shaft, it is possible to prevent the blade from slipping in the circumferential direction of the rotary shaft and rotate the blade integrally with the rotary shaft.

In the present invention, in order to prevent the blade from sliding in the thrust direction, a concave portion is provided in a portion of the rotary shaft to which the blade is attached, and an engaging portion that engages with the concave portion at a base end portion of the blade. Is preferably provided.

It has a structure provided with an outlet 20. The input port 12 is provided with a cutter 22 and a crusher 24 for shredding raw garbage. A grid 26 is provided at the discharge port 20. The lid 28 of the discharge port 20 is opened and closed by a handle 29.

The stirring blade 14 is rotationally driven by the motor 32 via the pulley 30.

At the top of the garbage processing tank 12, there is a ventilation inlet 3
4 and a ventilation outlet 36 are provided.

An opening 38 is provided in the ceiling portion of the garbage disposal tank 12, and the condensing plate 18 covers the opening 38 like a lid.

The condensing plate 18 has a gutter 42 on its inner surface for collecting condensed water. This condensing plate 18
Is pivotally attached to the garbage disposal tank 12 by a hinge 44 so as to be capable of tilting and turning. A downward L-shaped outflow pipe 46 is connected to the hinge 44 side of the gutter 42, and a falling water receiver 48 is provided below the lower end outlet of the outflow pipe 46. A drain pipe 50 for drainage is connected to the receiver 48.

A heater 52 is provided on the outer surface of the garbage processing tank 12.

The stirring blade 14 includes a rotating shaft 54 and blades 56A, 56B, 56b attached to the rotating shaft 54.
56C, 56c, 56D, 56d, 56E, 56e, 5
It consists of 6F. The rotary shaft 54 has a circular cross-sectional shape at the shaft supporting portions at both ends, but has a quadrangular cross-sectional shape other than that.

As shown in FIG. 3, a bracket 58 having a 90 ° corner portion is fixed to the base end of the blade,
A pair of blades are arranged on both sides of the rotary shaft 54, and the bracket 5
The blades are fixed to the rotary shaft 54 by overlapping the eight flanges 60 and tightening them with bolts. Rotating shaft 54
Has a rectangular cross-section, there is no risk of the blades slipping in the circumferential direction.

As shown in FIG. 3 (c), in the portion to which the blade is attached, the rotary shaft 54 is partially provided with a concave portion 62, and the engaging portion (triangular top) provided at the corner portion of the bracket 58. 64 is fitted in the recess 62. By fitting the locking portion 64 and the concave portion 62, the blade does not move in the thrust direction (rotation shaft axis direction) at all.

In this embodiment, the discharge port 20 on the bottom surface of the processing tank 12 is arranged below the intermediate portion in the longitudinal direction of the rotary shaft 54.

As clearly shown in FIGS. 3 to 5, triangular blades 56A, 56B, 56C, 56D, 56 having a triangular side view shape.
E and 56F have their respective vertices of triangles facing the direction of the intermediate point in the longitudinal direction of the rotary shaft 54 (that is, the direction of the discharge port 20), and are divergent in the direction away from this intermediate point.

Triangular blades 56B, 56C, 56D, 56E
The blades 56b, 56c, 56 adjacent to each other in the circumferential direction with respect to
d and 56e are provided. These plate-shaped blades 56b
Reference numerals 56e to 56e each have a flat plate shape, and the plate surface is inclined with respect to the thrust direction.

Plate blades 56b, 5 on the left half side of FIGS.
6c has an inclination opposite to the thrust direction with respect to the plate blades 56d and 56e on the right half side.

When the rotary shaft 54 rotates in the R direction of FIG. 5, as is apparent from the lower half (exploded view) of FIG.
All the blades draw the garbage in the direction toward the discharge port 20. Therefore, the treated raw garbage (product) can be quickly scraped to the discharge port 20 and discharged.

When the rotary shaft 54 rotates in the S direction in FIG. 5, all the triangular blades 56A, 56B, 56C, 5 are rotated.
6D, 56E, 56F draw the garbage toward the discharge port 20 as indicated by the white arrow in the lower half of FIG. However, the plate-shaped blades 56b, 56c, 56d, and 56e, on the contrary, draw the garbage toward the end. That is, the blades 56b and 56c on the left half side draw the garbage toward the left end, and the blades 56e and 56f on the right half side draw the garbage toward the right end. In this way, the triangular blades 56A, 56B,
The scraping direction of 56C and the plate-shaped blades 56b and 56c are reversed, and the triangular blades 56D, 56E, 56F and the plate-shaped blade 56.
Since the scraping directions of d and 56e are reversed, the garbage in the processing tank 12 is strongly stirred. At the time of this stirring, the raw dust on both ends of the rotary shaft 54 is scraped toward the middle of the rotary shaft 54 by the triangular blades 56A and 56F (that is, in the direction away from the inner wall of the processing tank 12). The garbage will not be pressed against the inner wall of the processing tank. Therefore, the garbage in the processing tank 12 can be efficiently stirred as a whole without locally staying.

Next, a method for treating raw garbage by the raw garbage treating machine 10 thus constructed will be described.

A processing medium is stored in the raw garbage storage chamber in the raw garbage processing tank 12. As the treatment medium, various types such as sawdust, chaff, rice bran, coconut chips, zeolite, wood chips, and okara are used.

Garbage disposal tank 12 for disposing of garbage from the inlet 16
It is put into the inside, and the stirring blade 14 is rotated in the direction of the arrow S to stir and mix the food waste and the processing medium, and the blower (not shown) uses air (warm air may be used or unheated atmosphere) May be supplied to the raw garbage processing tank 12 and the exhaust fan (not shown) discharges air from the raw garbage processing tank 12.

The amount of air sent by the blower is so small that oxygen is supplied to the microorganisms, the power consumption by the blower is reduced, and the amount of heat taken away by the exhaust is made small.

The stirring of the raw dust and the treatment medium by the stirring blade 14 does not lower the temperature of the raw dust in the processing tank 12,
Moreover, the water consumption is slow or low so that excess water is discharged from the mixed layer of the garbage and the processing medium into the space above the garbage collection chamber, and the power consumption by stirring is reduced.

As a result, the power consumption is low, and sufficient oxygen is supplied to the microorganisms so that the water content in the mixed layer of raw waste and the treatment medium is properly maintained, and the mixed layer of raw waste and the treatment medium is maintained. By maintaining the internal temperature at an appropriate temperature of about 60 ° C. and sufficiently enhancing the microbial activity, it is possible to perform microbial treatment of garbage.

The air containing moisture that has risen in the garbage collection chamber comes into contact with the condenser plate 18 to condense moisture. The water droplets travel along the condensing plate 18 and immediately fall into the trough 42, and are discharged to the outside of the machine through the outflow pipe 46, the receiver 48, and the drain pipe 50. Although the condensing plate 18 is air-cooled by the outside air, cooling means such as water cooling may be provided.

A device such as a trap may be provided in the drain pipe 50. The exhaust gas from the ventilation outlet 36 may be returned to the ventilation inlet 34 after being heated by an air heater after passing through a condenser.

After the processing is completed, the lid 28 of the discharge port 20 is opened, the stirring blade 14 is rotated in the direction of the arrow R, and the processed garbage (for example, compost product) is taken out of the machine.

[0038]

As described above, according to the garbage processing apparatus of the present invention, garbage can be efficiently stirred and treated with microorganisms.
After the treatment, the treated garbage can be discharged efficiently and promptly out of the machine.

According to the present invention, it is possible to firmly fix the blade to the rotary shaft.
