DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing device. More specifically, the present invention relates to a food waste disposal device having excellent operation stability, which can effectively prevent clogging of a drainage port after solid-liquid separation in food waste disposal.

[0002]

2. Description of the Related Art Conventionally, garbage discharged from homes and the like has been separated and collected, for example, incinerated, and then disposed of. However, this garbage disposal
In recent years, where social problems have been developed and the protection of the global environment has been called for, it is difficult to deal with such conventional garbage disposal alone.

[0003] Therefore, a search for garbage disposal in consideration of environmental conservation has begun to be sought. For example, as schematically illustrated in FIG. 8, a garbage crusher (a) called a disposer for crushing food waste (a) is installed in, for example, a sink sink section (c). The raw garbage (a) generated by cooking etc. is put into the disposer (a), finely ground, and then the ground raw garbage is discharged together with water.

Recently, in conjunction with the crushing process of food waste (a) by this disposer (a),
The inventors of the present invention have proposed a food waste processing apparatus for decomposing crushed food waste in a place where it is generated, such as at home, to almost no trace (Japanese Patent Application No. 6-13).
7670). This food waste processing device can be shown, for example, in the cross-sectional view of FIG. 9, and has an input port (e) for introducing crushed food waste from the disposer (a) on the upper surface of the device body (d). A treatment tank (f) is provided inside the apparatus main body (d), a solid content treatment portion (ki) is formed in the upper portion thereof, and a waste water treatment portion (k) is formed in the lower portion thereof. The solid content treating section (g) is filled with a solid content treating medium (ke) such as wood chips in which microorganisms are parasitic, and an agitating device (g) for periodically agitating this.
Is provided. On the other hand, in the wastewater treatment unit (K), a drainage port (S) is formed on the bottom surface and the lower side wall. Of these, a pin (shi) for preventing clogging can be freely inserted into the drain port (sa) provided on the bottom surface of the waste water treatment part (h). ) Is connected to the processing tank (f), and it can be moved up and down.

A water storage tank (C) is provided immediately below the processing tank (F). In the food waste disposer having such a configuration, when the crushed food waste is thrown from the disposer (a) into the processing tank (f) inside the device body (d) through the input port (e), the crushed food waste is crushed. The solid content in the refuse is decomposed by the solid content processing medium (K) filled in the solid content processing section (K) above the processing tank (F). The water flows out to the water storage tank (C) through the drainage port (S) formed in the wastewater treatment unit (K). The side wall of the device body (d) is provided with a discharge port (so) at a predetermined height, and when the amount of stored water exceeds a certain amount, water is discharged through this discharge port (so). Is discharged from the outside.

[0006]

However, the decomposition processing is performed at the place where such garbage processing occurs.
Although it is a food waste disposal device that puts one stone into the problem of food waste disposal, in order to make it a mature device, it is necessary to further examine the details. Disposer-linked food waste treatment devices have a problem in that the drainage port after solid-liquid separation is likely to be clogged. Therefore, in the device shown in FIG. 9, a pin (si) is inserted into a drainage port (a) provided on the bottom surface of the wastewater treatment section (h) to prevent clogging, and even if clogging occurs. It is devised so that it can be eliminated.

However, like the device of FIG. 9,
The solid content treatment medium (K) is gradually consolidated by the stirring of the solid content treatment medium (K) by the stirrer (U), and the consolidation force becomes maximum at the bottom of the wastewater treatment unit (K).
For this reason, in the case of the device shown in FIG. 9 in which the drain port (service) is provided on the bottom surface, the pin (si) is inserted from the drain port (service)
Even if the solid content treatment medium (K) is pushed up, the drainage capacity cannot be denied.

At the same time, there is also a problem that undecomposed substances such as the solid content treating medium (ke) and ash are likely to flow out from the drainage port. This invention has been made in view of the circumstances as described above, eliminates the drawbacks of the conventional food waste disposal device, and effectively eliminates clogging of the drainage outlet after solid-liquid separation in food waste disposal. Can be prevented,
It is an object of the present invention to provide a food waste processing device having excellent operation stability.

[0009]

Means for Solving the Problems As a solution to the above problems, the present invention is connected to a garbage crusher and communicates with a solid content treatment tank for decomposing and treating the solid content of crushed food waste. A garbage disposal device equipped with a wastewater treatment tank, which is equipped with rotary stirring blades and has a slit shape in which the wastewater treatment tank communicates with the lower side surface of the solid content treatment tank filled with the solid content treatment medium. Is equipped with a plate-shaped clogging prevention blade that can be moved back and forth, and this clogging prevention blade is connected to the rotary shaft of the rotary stirring blade and synchronized with its rotation. There is provided a food waste processing device characterized by performing reciprocating motion.

[0010]

[Operation] In the food waste processing device of the present invention, as described above, the drain port provided in the solid content processing tank and the plate-like clogging prevention blade disposed so as to be movable back and forth are rotated. I try to reciprocate in synchronization with. By having such a configuration, the food waste processing device of the present invention,
The drainage capacity of the solid content treatment tank can be maintained for a long period of time. Moreover, the structure therefor can be simplified, and the device becomes compact.

By the operation of the air blower (8), oxygen is supplied to the water through the air diffuser (7), the aerobic microorganisms are activated, and the dissolved pollution source in the water can be decomposed and removed.

The inner bottom surface of the waste water treatment tank (6) is formed in an inclined surface so as to rise toward the discharge port (9) provided on the side surface. An air blower (8) is built in between the inner bottom surface and the bottom surface of the main body. By such a wastewater treatment tank (6), the water sent from the solid content treatment tank (3) is treated, and when the water level exceeds a certain level, the discharge port (9).
More treated water is discharged to sewage. A partition plate (10) is provided near the discharge port (9) so as to hang down from the upper surface of the wastewater treatment tank (6) so as to prevent water pollution such as sewage. The presence of the partition plate (10) prevents outflow of untreated water.

Further, the wastewater treatment tank (6) is also provided with an underwater pump (11).
1) is connected to the solid content treatment tank (3) by a pipe line (12). As a result, the sludge (12) in the water can be returned to the solid content treatment tank (3) and decomposed. The wastewater treatment tank (6) and the solid content treatment tank (3) may be integrated with the apparatus,
Alternatively, it may be provided separately from the solid content treatment tank (3). When it is provided as a separate body, it does not necessarily have to be provided below the solid content treatment tank (3) as in the example of FIG. 1, and its position is not particularly limited as long as it is arranged in parallel.

[0016] In such a food waste treating apparatus, further, the solid content treating medium can be decomposed efficiently and stably in the solid content treating tank (3) so as to decompose it efficiently. A mechanism for periodically stirring (4) is provided. That is, in the example of FIG. 1, two horizontal rotary shafts (13) and (14) are provided in the solid content treatment tank (3). These rotating shafts (13)
Each of the (14) is provided with a stirring blade (15) at a position where they do not come into contact with each other by the rotation of the rotating shafts (13) and (14). A motor (16) is built in above the solid content processing tank (3), and an appropriate power transmission means (1) such as a pulley and a belt, a gear and a chain is provided.
By 7), the rotational force of the motor 16 is transmitted to the respective rotary shafts 13 and 14. The rotating shafts (13) and (14) are rotated by the rotation of the motor (16), and the stirring blades (15) are rotated inside the solid content processing tank (3) to allow stirring of the solid content processing medium (4). Becomes Solid content processing medium (4) driven by such a motor
The stirring can be performed at a slow rotation speed of, for example, about 2 to 3 times per hour. Of course, the number of times of stirring can be set appropriately. Further, the number of rotating shafts and the number of stirring blades installed on the rotating shafts are not limited at all. For example, it may be an appropriate number depending on the volume, size, etc. of the solid content treatment tank (3).

In this food waste processing device,
A mechanism for preventing clogging of the drainage port (5) provided at the lower portion of the side surface of the solid content treatment tank (3) is provided. As described above, the drainage port (5) is provided in the lower portion of the side surface of the solid content treatment tank (3), and the compaction of the solid content treatment medium (4) is smaller than in the case where it is provided on the conventional bottom surface. ing. However, the solid content treatment medium (4) is periodically agitated by the agitation mechanism in order to effectively decompose the solid content of the crushed food waste, so that the compaction gradually increases with use.

Therefore, in this example, the clogging prevention blade (18) is inserted into the drainage port (5), and the clogging prevention blade (18) is moved back and forth in and out of the solid content treatment tank (3). I am free. More specifically, as shown in the sectional view of the main part of FIG. 3, the rotating shaft (14) close to the drainage port (5).
A camshaft (20) having a cam surface (19) formed on its inner surface is attached to the end of the.

On the other hand, the clogging prevention blade (18) is provided at the lower end of the arm (21). In this example, the clogging prevention blade (18) is a plate body formed in an arc shape. The arm portion (21) is arranged in contact with the cam surface (19) so that its upper end follows the cam surface (19) of the cam shaft (20). The arm portion (21) is also supported by a fulcrum (22) at one point in its length direction. Support point (22)
Are supported on the side surface of the solid content treatment tank (3).

With such a structure, the rotating shaft (14)
The rotational movement of the cam shaft (20) and the arm portion (2
1) is converted into a plane movement of the clogging prevention blade (18), and the plane movement of the clogging prevention blade (18) is synchronized with the rotation movement of the stirring blade (15) provided on the rotation shaft (14). Will be done. For example, the clogging prevention mechanism of the drainage port (5) having the above configuration operates as follows.

As illustrated in FIG. 3, when the stirring blade (15) arranged closest to the clogging prevention blade (18) comes to the bottom of the solid content treatment tank (3), the clogging prevention blade ( 18) retreats from the drain port (5) to the outside of the solid content treatment tank (3). However, the clogging prevention blade (18)
The tip of the is retained in the drainage port (5).
Therefore, even if the clogging prevention blade (18) retracts, the drain port (5) does not fully open, and the solid content treatment medium (4) can be prevented from flowing out from the drain port (5). it can.

The rotation shaft (14) is rotated by the operation of the motor (16) illustrated in FIG. 1, and the stirring blade (15) is separated from the bottom of the solid content treating tank (3) as shown in FIG. Figure 3
When it is rotated 180 ° from the position of,
The clogging prevention blade (18) enters the inside of the solid content treatment tank (3). Since the clogging prevention blade (18) has an arc shape, the clogging prevention blade (18) makes a circular motion about the fulcrum (22). As a result, the movement of the clogging prevention blade (18) has not only a horizontal component with respect to the solid content processing tank (3) but also a vertical component.

As shown in FIG. 4, when the clogging prevention blade (18) deeply enters the solid content processing tank (3), the solid content processing medium filled in the solid content processing tank (3). (4) is lifted and loosened by the clogging prevention blade (18). The disentangling effect of the solid content treatment medium (4) can be further increased by overlapping the motion regions of the stirring blade (15) and the clogging prevention blade (18). Adjustment of the motion area of the stirring blade (15) and the clogging prevention blade (18) is easy because they move in synchronization.

Since the clogging prevention blade (18) makes a circular motion around the fulcrum (22), as shown in FIG. 2, the clogging prevention blade (18) and the drainage port (5) are connected to each other. It is also possible to keep the clearance constant. In this way, it is possible to effectively prevent clogging of the drainage port (5) after solid-liquid separation, and it is possible to maintain the drainage capacity stably for a long period of time. In order to effectively decompose the solid content of the crushed food waste, the solid content treatment medium (4) may be agitated by the agitating blades (15), and even if it is compacted, it is possible to loosen the compacted state. it can. Further, the mechanism for operating the clogging prevention blade (18) is directly connected to the stirring blade (14),
Moreover, it is simple and the device becomes compact.

The stroke length of the circular motion of the clogging prevention blade (18) is determined by the cam surface (1) of the camshaft (20).
By changing the shape of 9), the length of the arm portion (21), the position of the fulcrum (22), etc. singly or in combination, a suitable length can be adjusted. The variations are wide. Further, in the food waste processing device of the present invention, as illustrated in FIG. 5, the drain port (5) can be provided only on the lower part of one side surface of the solid content processing tank (3). In this case, in order to effectively perform wastewater treatment,
The bottom surface of the solid content treatment tank (3) is preferably an inclined surface that descends toward the drain port (5).

Further, as shown in FIG. 6, when a rotating drum (23) is provided inside the solid content treating tank (3) as a substitute for the stirring blade, the rotating shaft of this rotating drum (23). A camshaft (20) can be attached to (24) to have the same configuration as described below. FIG. 7 is a sectional view showing still another example of the food waste processing apparatus of the present invention.

In the example of FIG. 7, in order to clarify and stabilize the discharged water quality to be discharged, a membrane module (25) is provided in the waste water treatment tank (6) and a suction pump (2) is provided.
According to 6), water is forced to pass through this membrane module (25) and is discharged to the outside of the device via this. There are no particular restrictions on the membrane module (25),
For example, a hollow fiber membrane, a flat membrane or the like can be used. The membrane separation by the membrane module (25) enables highly efficient removal of pollutant components from the water fed from the solid content treatment tank (3). The quality of the treated water can be greatly improved and the quality of the water becomes stable. Reuse of treated water is also possible. In addition, the microbial concentration can be kept high, and nitrification proceeds.

As described above, only by providing the membrane module (25) in the wastewater treatment tank (6), a great effect can be obtained in improving the quality of the treated water, and the apparatus for wastewater treatment can be downsized. Since the membrane module (25) is cleaned by the air sent through the air diffuser pipe (7), its performance is maintained at high quality and stably. Of course, the present invention is not limited by the above examples. It goes without saying that various aspects are possible for details such as the configuration and structure of the solid content treatment tank and the wastewater treatment tank.
