Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the treatment of organic wastes such as food-related industries, processing plants for agriculture, forestry and fishery products, livestock manure, food left over from general households, and vegetable waste.

[0002]

2. Description of the Related Art Since the inner wall of a processing tank of an existing garbage processing apparatus requires strength and a material that does not rust, it is mainly made of a thick metal such as stainless steel that does not rust. The system is heated with hot air to promote fermentation and drying.Insulation and heat insulating materials are used on the outer wall of the processing tank to improve the heat insulation, and it is covered with an outer plate for exterior. ing.

[0003] A heater used to introduce hot air into the processing tank and a hot air introduction path from the heater into the processing tank employ heat insulating means that is covered with a heat insulating material or a heat insulating material. The heat is released by the convection of the air inside the device and the conduction of the device structure and the outer panel, and as a result, wasteful heat is wasted.

In the case where the stirring rotary shaft is hollow and used as a part of a hot air introduction path into the processing tank, a bearing supporting the rotary shaft, a hot air introducing portion and a processing chamber of the rotary shaft are used. The temperature of the seal portion of the introduction portion is forced to rise due to the heat of the hot air directly transmitted through the rotating shaft, thereby shortening their durable life.

[0005] In a vertical garbage disposal apparatus in which the stirring axis is positioned vertically, the shape of the stirring blade used for stirring the contents in the processing tank is a rectangular plate or the like in the rotation direction. The stirring function is improved by tilting or twisting to increase the stirring function by rotating and lifting the contents, but since the stirring blades do not generate a stirring force in the radial direction, the outside of the processing tank It is not possible to efficiently mix contents near the center and contents near the center,
In addition, the "co-rotation" phenomenon in which the processed material rotates together with the stirring blade easily occurs due to the density and viscosity of the content.

[0006] When the object to be treated is put into the treatment tank without being crushed or crushed, especially the root material typified by potatoes and carrots, the epidermis of the root material has resistance to microorganisms. Therefore, it is difficult to decompose by fermentation, and the treatment is finished in a dry state.

As described above, since the whole vegetable cannot be put into the processing machine, when using a garbage processing machine without a crusher or the like, the whole vegetable or the like is finely chopped in addition to separating the garbage. I had to.

When the hot air introduced into the processing tank passes through the processing object, it introduces air to the processing object in the processing tank and heats the processing object. At this time, the introduced fluid is discharged after being cooled and humidified, but is discharged to the outside air at a higher temperature and humidity than the outside air, or is guided to a deodorizing device or the like which is a secondary treatment. Therefore, a considerable amount of heat is wasted and wasted.

[0009]

Since the treatment tank needs comprehensive strength including acid resistance and abrasion resistance, it is also necessary to process an outer plate for exterior and a frame for fixing the treatment tank. Since it is necessary to apply a coating process to prevent corrosion and rust on the outer panel, the cost of materials and processing increases, and compactness and cleanliness are reduced while reducing the initial and running costs of equipment required by society. It is difficult to maintain a good image.

[0010] The waste of heat generated from a heating device such as a heater is directly reflected in the running cost of the device.
This is contrary to the reduction of adverse effects on the global environment by recycling garbage, which is the primary purpose of processing garbage as fertilizer. Therefore, it is necessary to reuse the waste heat for processing in order to reduce the waste heat, and to improve the thermal efficiency to the maximum.

In a vertical garbage processing apparatus in which the stirring axis is positioned vertically, if the contents of the processing tank can be efficiently stirred not only in the rotating direction but also in the radial direction by rotating the stirring blade. , Stirring not only in the vertical direction but also in the horizontal direction will occur, and the stirring efficiency will increase dramatically,
Increases processing efficiency.

If roots typified by potatoes and carrots can be wounded in the processing tank so as to peel them, microorganisms can enter the roots from the wound and start fermentation and decomposition. Ability can be improved.

If the amount of heat of the exhaust fluid discharged from the processing device can be reused without escaping to the outside as much as possible,
Not only is the thermal efficiency of the entire processing apparatus increased, but also the burden on the environment can be reduced.

[0014]

SUMMARY OF THE INVENTION The present invention is intended to address these problems. The use of water / water pipes or fume pipes coated with glass fiber or plastic for the treatment tank or exterior makes it possible to reduce the material of the pipes. The function reduces noise and improves heat retention, and does not require rusting because it is not a rusting material.

In addition, by using a water pipe or fume pipe coated with glass fiber or plastic as a double pipe structure for both the processing tank and the exterior, the conventional framework for supporting the outer plate of the processing tank and the exterior becomes unnecessary. Since the outer tube combines the outer tub and the outer plate, it is possible to design a compact, low-cost garbage disposer with a cylindrical shape, reduce noise, maintain heat, and maintain structural strength. In terms of the above, the performance can be improved as compared with the garbage disposal apparatus designed by the conventional method.

Bearings or seals that reuse the heat generated from the outer surface of the heater itself or the outer surface of the hot air introduction path from the heater to the inside of the processing tank without escaping to the outside and may be installed in the hot air introduction path. In order to make it possible to cool the heater and the hot air introduction path with a suitable space, the wall is surrounded by a partition wall so as to allow cooling by introducing outside air,
Connect the gap to the intake side of the blower.

If the shape of the stirring blade is set to the shape of a plow employed in agriculture, and the treated material is plowed when stirring, the stirring efficiency is significantly improved. This can be realized by shifting the whole or a part of the stirring blade backward or forward from the radial direction from the center of the stirring shaft toward the center of the blade, and the processed material on the upper surface of the shifted portion of the blade is When the blade is shifted backward from the radial direction, it is pushed toward the center of the processing tank, and when shifted forward, it is pushed toward the outer periphery of the processing tank.

Contrary to the above, if the portion close to the center of rotation of the blade is displaced backward from its rotational radius direction and the other portion is displaced forward, the processed object will hit the blade and rotate in the rotational direction of the blade. Are divided into left and right parts.

One or several rod-shaped objects or projections fixed in the processing tank are provided, and a mechanism is provided for colliding with the processed object stirred and moved by the stirring blade. The projections can be scratched when colliding or rubbed.

[0020] At this time, there is a place where microorganisms that are sufficiently surviving can enter the contents of the processed material, and the place increases with time, so that the fermentation decomposition is accelerated. For this reason, roots and the like that have been input without being cut or crushed in advance are efficiently processed.

By providing a heat exchanger in the path of the exhaust fluid discharged from the processing tank and introducing the outside air sucked by the blower as the exchange fluid of the heat exchanger, the outside air temperature can be increased in front of the heater. By using a large amount of heat that has been discharged and discarded, the outside air drawn into the processing apparatus is preheated.

[0022]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view for explaining the outline of the whole garbage disposal apparatus, FIG. 2 is a plan view of the whole garbage disposal apparatus,
FIG. 3 is a side view of the whole garbage disposal apparatus. As shown in FIG. 1 and FIG. 2, the pipe end of the fume tube (3) is set upright on the upper surface of the bottom plate (1) in such a manner that the tube end is in close contact with the upper plate (5) so that the upper part of the fume tube (3) is closed. By attaching, the processing tank (10) which is a garbage processing space is formed.

A stirrer (7), a blower (8) and a heater (9) are arranged on the upper plate (5) with the fume tube (3) as a housing, and a stirrer shaft (18) rotated by the stirrer (7). The stirrer (6) fixed to the rotator rotates, and the air sent from the blower (8) is heated by the heater (9) to stir the stirrer (1).
It is sent to the processing tank (10) via 8).

The treatment tank is placed vertically above the bottom plate (1) and outside the fume tube (3) as an exterior with the fume tube (2) having a diameter slightly larger than the fume tube (3) and a height. By forming the space (4) up to the height of (10), the sound insulation effect and the heat insulation effect of the treatment tank (10) are improved, and the top plate (12) is placed on the top of the fume pipe (2). A robust driving room (11) is formed, and noise generated from the driving unit is cut off.

FIG. 4 is a schematic diagram showing a hot air introduction path to the heater and the processing tank. The heater (13) is installed in a heater box (14) surrounding the heater, and the outside air sent from the blower enters the heater box (14) from the air intake (15), is heated by the heater (13), and is sent out with hot air. Hot air introduction path (17) from mouth (16)
Is fed into the hollow agitating shaft (18), and is guided into the processing tank (19).

A space (21) is provided to cover the heater box (14), the hot air introduction path (17), and the housing (20) of the bearing and seal supporting the stirring shaft (18). The partition (22) has an outside air intake (23) and an outlet (2) connected to the intake side of the blower.
4).

When the blower is operated, the outside air enters the air gap (21) from the air intake (23), while cooling the bearing and seal housing (20) while passing through the air gap (21). Therefore, it is heated by the heat released from the hot air introduction path (17) and the outer wall of the heater box (14), and is introduced into the blower from the partition outlet (24).

The heating fluid compressed by the blower (8) is sent from the air intake (15) to the heater box (14), and is further heated to a target temperature by the heater (13). The hot air is sent from the hot air outlet (16) through the hot air introduction path (17) to the inside of the processing tank (19) through the stirring shaft (18).

The structure of the stirring blade will be described with reference to FIG. FIG. 5A shows the shape of a general stirring blade in which a rectangular blade is inclined at an angle. The center line (25) of the blade (50) and the center line (26) of the stirring shaft (18) are on the same line, and little deviation between them is considered.

FIG. 5B shows the entire blade as its center line (2).
5) is a shape obtained by shifting the line (26) passing through the center of the stirring shaft in the forward direction (31) by a distance (30) with respect to the rotation direction (27) in the direction indicated by an empty arrow in the figure. A force (51) is generated.

FIG. 5C shows a blade center line (25) in a portion near the rotation center of the stirring blade and an axial center line (2
6) is shifted in the forward direction (33) with respect to the rotation direction (27) by the distance (32), and the blade center line (25 ') of the portion outside the stirring blade is parallel to the axial center line (26'). Is a shape shifted in the backward direction (35) with respect to the rotation direction (27) by the distance (34). In this case, the stirring force due to the rotation of the blades is indicated by an empty arrow in the figure,
A force (40) is generated that pushes the workpiece toward the joint (29) of the two blades.

FIG. 5D shows a case where the displacement of the portion near the rotation center of the stirring blade and that of the outer portion thereof are opposite to each other in FIG. 5C, and the stirring force is applied to the joint between the two blades. From (29), a force (41) for pushing in the cutting direction is generated.

As an embodiment, a fixing rod (51) shown in FIGS. 1 and 2 has one end fixed to the processing tank pipe (3), and the other end fixed to the stirring shaft (18) by a bearing unit (52). It is a rod-like object supported and fixed at a position where it does not hinder the rotating stirring blade (6).

The fixed projections (53) shown in FIGS. 1 and 2 are fixed to the inner wall of the processing tank tube (3) at a position where they do not hinder the rotating stirring blade (6).

The fixed rod (51) and the fixed protrusion (53) act to hinder the rotation of the processing object in the processing object that is rotating with the rotation of the stirring blade, and may collide with the processing object. In addition, an effect of grinding the processed material is produced. Also,
This prevents the whole processed material from rotating together with the stirring blade.

These fixing rods or fixing protrusions have been tested in various shapes and have been found to exert various effects depending on their size and shape.

For example, it has been confirmed that when a blade having a bow-like shape like a Japanese sword is attached as a fixed rod, not only the processed material is damaged but also cut even though the rotation by stirring is low. . When a protrusion is used, a shape having corners is more effective than a round shape.

When the fixed rod is approached to the stirring blade at an angle from the radial direction as shown in (54) of FIG. 1 and fixed so that the processed material is sandwiched between the fixed rods by rotating the stirring blade. The effect doubles.

As shown in FIG. 6, the exhaust fluid (44) discharged from the processing tank passes through the filter (43) and then enters the high-temperature side inlet (45) of the heat exchanger (42). It is discharged out of the processing device from the outlet (46). After the outside air is introduced from the low temperature side inlet (47) of the heat exchanger (42) and receives the heat of the high temperature side exhaust fluid in the heat exchanger and is heated, the blower ( The air is sent to the intake side of 8) or the outside air inlet (23) shown in FIG.

Exhaust fluid exhausted from the processing tank (44)
Is hotter and humid than the outside air, and the water that is cooled by the outside air on the low temperature side in the heat exchanger (42) and exceeds the saturated water amount condenses,
The condensed water is discharged from the drain (49).

[0041]

Since the manufacturing cost of the garbage disposal apparatus according to the first and second aspects can be kept low, it can be provided at a low cost, the running cost can be reduced by the heat insulation effect, the sound insulation effect by the sound insulation, and the compact and simple. In addition, there is an advantage that the design becomes a cylindrical shape that is easy to get close to.

In the garbage disposal apparatus according to the third aspect, the taken-in outside air has a function of cooling the bearing and the seal portion which must be heated by the hot air, and has a function of extending the durable life of the bearing and the seal portion. A method of improving the cooling effect by providing a shape such as a fin on the outer surface of the housing holding the bearing and the seal portion and increasing the surface area thereof further enhances the effect of the present invention.

After cooling the bearing and the seal portion, the introduced fluid traveling in the partition wall is heated by the heat released from the hot air introduction path and the heater. As a result, the air taken into the blower is preheated, and the air is preheated. Sent to the heater,
The release of heat outside the heating system can be reused, and the release of heat outside the device can be significantly reduced.

In such a garbage disposal apparatus, when the introduced outside air is heated to a set temperature, the heater is turned on / off by a thermostat or the like, so that the temperature of the air sent into the heater is controlled. The time during which the heater is energized depends on the time. That is, when the outside air temperature is high, the time for energizing the heater is short, and when the outside air temperature is low, the energization time is long.

Therefore, in the garbage disposer according to the third aspect, the outside air is preheated by the heat discharged from the heater and the surrounding high-temperature portion without being used, so that the outside air is treated as if the outside air temperature is high. Thus, the time for energizing the heater is reduced, which contributes to the reduction in power consumption.

Further, if the heater can be installed so that the hot air introduction path from the heater outlet to the processing tank can be shortened as much as possible, a better effect can be obtained. In particular, when the stirring shaft is hollow and it is directly connected to the hot air introduction path for use. By connecting the hot air introduction path, which is as short as possible, to the stirring shaft and connecting it to the heater, if the heater is positioned above the stirring shaft, an integrated structure of the heater and the partition that covers the hot air introduction path becomes possible. It can also contribute to miniaturization of the device.

In the garbage disposal apparatus according to the fourth aspect, since the movement of the processed material in the horizontal direction is forcibly caused by the stirring operation, the stirring efficiency is increased. As a result, the fermentation conditions can be made uniform and the processing time can be shortened, so that a better product can be produced.

In particular, if the portion near the center of rotation of the blade is displaced before the radial direction of rotation and the other portion is displaced afterward, the processed object is simultaneously pushed inward from the outer periphery toward the outer periphery from the center. Therefore, a better effect is exhibited.

In the garbage disposal apparatus according to the fifth aspect, the processed material that slowly rotates over time is gradually damaged, and the wound expands with time. The function of the microorganisms living in the treatment tank promotes the fermentation and decomposition of the treated material in proportion to the size of the wounded area. In addition to shortening the processing time, it is also possible to treat garbage such as uncrushed roots by an inexpensive method.

In the garbage disposal apparatus according to the sixth aspect, the calorific value of the exhaust fluid can be efficiently reused and the release to the outside air can be reduced to the maximum, leading to a reduction in running costs.

Since the exhaust fluid humidified in the processing tank is cooled by the outside air, moisture contained in the exhaust fluid is condensed in the heat exchanger and separated from the exhaust fluid. Normally, the exhaust fluid from garbage disposers often has an odor, but the more it is cooled, and the lower the water content, the more its odor is reduced, and the deodorization by a deodorizer etc. It also contributes to higher efficiency.
