Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a garbage disposer for heating and drying garbage discharged from factories, restaurants, households, hotels and the like to reduce the amount of garbage.

[0002]

2. Description of the Related Art Garbage generally contains a large amount of water.
Therefore, various problems such as difficulties in bringing to the garbage collection area, dirty storage containers and places, and the decay progressing in a short time when the temperature is high, causing odor, etc. Having.

[0003] The composition of garbage is varied and varied depending on the establishment where the garbage is generated. Therefore, as a means for pulverizing and stirring garbage, a paddle system or a screw blade system provided with a mountain-shaped saw blade is generally used.

[0004]

However, the above-mentioned conventional garbage disposer has a large driving resistance required for crushing garbage, and dust is clogged between the blades, so that a sufficient crushing effect cannot be obtained. However, since efficient drying cannot be performed, the processing time is prolonged.

Accordingly, the present invention has been made in view of such circumstances,
It is an object of the present invention to provide a garbage disposer capable of stirring and pulverizing garbage irrespective of its type and size, and obtaining high drying efficiency.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cylindrical lower stage in which a screw with a saw blade for crushing and stirring garbage is provided, and high-temperature air is flowed in and heated and dried. In the garbage disposer provided with a drying container, a plurality of convex protrusions are provided inside the lower drying container, and a plurality of discontinuous fixed blades are provided in parallel with a longitudinal axis direction of the lower drying container. The height relates to a garbage disposer characterized in that the height is not more than the height of the fixed blade.

[0007]

According to this structure, garbage is gripped by the saw blade of the screw with a saw blade on the bottom surface of the lower drying container and cut by a plurality of convex protrusions provided inside the lower drying container. The garbage that is not cut or cut is surely cut by the discontinuous fixed blade provided higher than the height of the protrusion, so that the garbage is finely crushed as a whole and the saw blade provided on the screw with the saw blade is removed. Since the garbage does not adhere to the front surface of the lower drying container due to the peeling action by the rotation, the rotation of the screw with the saw blade becomes smooth. However, the screw with a saw blade can sufficiently pulverize and agitate with a small driving force, and the input garbage is finely pulverized as a whole.

The circulating air inlet 11 and the circulating air outlet 13 communicate with each other through the circulating fan 14. A temperature sensor 10 for detecting the air temperature is provided near the circulating air outlet 13.

As shown in FIGS. 4 and 5, a plurality of discontinuous fixed blades 15 parallel to the longitudinal axis of the lower drying container 5 and a plurality of convex protrusions 15A are provided inside the bottom of the lower drying container 5 as shown in FIGS. I have. Note that the height of the convex protrusion 15A is equal to or less than the height of the fixed blade 15.

Further, a screw 1 with a saw blade is provided as a pulverizing / stirring means provided with a reverse blade 16 on a side remote from the discharge section 3.
7 is provided therein, has a waste discharge port 18 for discharging dry waste in the transport direction thereof, and a screw 17 with a saw blade on the outside.
A stirring motor 19 for driving is provided. Reference numeral 20 denotes a motor rotating means for rotating the stirring motor 19 in the normal and reverse directions so that the garbage reciprocates between the reverse blade 16 and the waste discharge port 18.

The bottom heating chamber 6 has a gas inlet 21 through which flue gas to be described later flows, and a gas outlet 24 through which flue gas flowing from the inlet 21 flows into an exhaust duct 23 having an exhaust fan 22. Have.

The high-temperature air generating section 2 includes a combustion fan 25, a burner 26, a vaporizer 27 for supplying fuel gas to the burner 26, and an odor air combustion chamber 29 communicating with the odor air outlet 9 through an odor air duct 28. , An orthogonal heat exchanger 30, a communication duct 31 for communicating the gas inlet 21 with the orthogonal heat exchanger 30, and a deodorizing catalyst 3 provided at an appropriate position of the communication duct 31.
2. It has a high-temperature air supply fan 34, a high-temperature air duct 35 that communicates the high-temperature air inlet 8 with the orthogonal heat exchanger 30, and the like.

The burner 26 has a secondary air ejection plate 38 in which a number of secondary air holes 37 for ejecting secondary air are formed, and is opposed to both sides of a crater 39. The orthogonal heat exchanger 30 is surrounded by a narrow passage 36. On the other hand, the odorous air combustion chamber 29
Has a double structure having an outer peripheral passage 40 communicating with the odor air duct 28 on the outside, and the inside and the outside communicate with each other through the odor air ejection holes 41 drilled below the opposing wall surface. .

The discharge section 3 includes a discharge cylinder 42 communicating with the waste discharge port 18, a discharge piston 43 provided in the discharge cylinder 42, and an open end at the other end of the discharge cylinder 42.
The outlet 44 is provided. The discharge piston 43 is connected to a discharge motor 45 via a trapezoidal screw, and a container 46 for receiving a dry garbage is attached below the discharge port 44.

Next, the operation of the above configuration will be described. When the garbage is thrown in by opening the charging lid 7 and the operation is performed, preparation for combustion such as preheating the vaporizer 27 is started. When the preheating is completed, an oil pump (not shown) is started, kerosene flows into the vaporizer 27, and the vaporized gas that has been heated and vaporized is ejected to the burner 26. On the other hand, the combustion fan 25 is also started at a low speed, and the primary air flows into the burner 26. Therefore, the premixed gas of the vaporized gas and the primary air flows out of the crater 39 and ignites, and the combustion starts. Further, the secondary air is forcibly supplied to the flame from the secondary air holes 37 to complete combustion.

The combustion exhaust gas heats the orthogonal heat exchanger 30 and the deodorizing catalyst 32, further flows into the bottom heating chamber 6 from the communication duct 31, and raises the temperature of the bottom of the lower drying vessel 5. Thereafter, the combustion exhaust gas is exhausted by the exhaust fan 2 started simultaneously with combustion.
2 and is discharged outside the machine through the exhaust duct 23.

In addition, before and after the start of combustion, the circulation fan 1
As soon as 4 starts, the stirring motor 19 is driven by the motor rotation means 20, and the garbage is stirred and pulverized by the screw 17 with the saw blade, the fixed blade 15 and the convex protrusion 15A, and the surface area is enlarged. In addition, the motor rotation means 20 starts the rotation with respect to the stirring motor 19 such that garbage is collected in the reverse blade 16. With this configuration, it is possible to completely prevent the wall 17 in the drying unit 1 from being locked with the screw 17 with the saw blade at the beginning of the startup.

At the time of stirring and pulverizing, the motor rotating means 20 rotates the stirring motor 19 in the forward and reverse directions, so that the garbage in the drying section 1 spreads as shown in FIG. In the reverse rotation, the stacked state is repeated as shown in FIG.

Further, as shown in FIG. 5, the garbage added to the saw blade of the screw 17 with a saw blade is cut or cut by a plurality of convex protrusions 15A provided inside the lower part of the lower drying vessel 5. Unremoved garbage is surely torn by the non-continuous fixed blade 15 provided higher than the projection height. That is, the input garbage is finely crushed as a whole, can come into wide contact with hot air, and can be efficiently dried.

Further, since the fixed blade 15 is made discontinuous, the rotation of the saw blade provided on the screw 17 with the saw blade makes it easy for the garbage fixed in the gap to be separated from the inner surface of the container, and the garbage is removed from the entire drying container. Therefore, the driving force of the stirring motor 19 required for pulverization is reduced. Furthermore, since heat transfer from the bottom heating chamber 6 to the garbage is not hindered, a high drying effect can be obtained.

On the other hand, the high-temperature air supply fan 34 is started at the same time as the start of combustion, and the blown air is sent to one narrow passage 36 on the outer periphery of the orthogonal heat exchanger 30. Then, the blast flows into the orthogonal heat exchanger 30, and the blast passing through each part of the orthogonal heat exchanger 30 exchanges heat to become high-temperature air, and the other narrow passage 36.
And enters the drying section 1 through the high-temperature air duct 35 and the high-temperature air inlet 8.

The high-temperature air flowing into the drying section 1 flows near the circulating air suction port 11. Therefore, the circulation fan 14 sucks a part of the high-temperature air from the circulation air suction port 11 and vigorously blows downward from the circulation air outlet 13 as a hot air of about 110 ° C. The reason why the high-temperature air is not directly introduced into the circulation fan 14 is a result in consideration of the heat resistance of the circulation fan 14 which is generally used. good.

The high-temperature air that has flowed into the drying unit 1 efficiently dries garbage having an increased surface area that repeats spreading and stacking while being pulverized and stirred. Then, it comes into contact with the garbage and becomes moist odor air, flows into the peripheral passage 40 through the odor air outlet 9 and the odor air duct 28, and blows out from the odor air outlet 41 into the odor air combustion chamber 29.

As described above, while the garbage is dried by the inflow of high-temperature air, a large amount of water collected at the bottom of the lower drying vessel 5 is removed from the garbage itself or the screw 1 having a saw blade.
7 hardly dries due to obstructing the path of high-temperature air. For this reason, the bottom of the lower drying container 5 is heated by the combustion exhaust gas (for example, 120 ° C.), and the garbage is dried by using a combination of high-temperature air and bottom heating, thereby increasing the drying efficiency.
Drying of garbage is completed in a short time

Since the burner 26 is forcibly supplied with the secondary air and burns, the length of the flame is short and the high-temperature air generator 2 can be formed compact. Further, since the flame temperature is high, the odorous air combustion chamber 29 located at the tip of the flame is
For example, the temperature becomes 900 ° C. or higher. Therefore, the odor air ejected from the odor air ejection hole 41 is heated and decomposed when the odor component comes in contact with the high temperature.

Since the odor air is not used as the combustion air, the efficiency of removing odor components is slightly reduced. However,
A deodorizing catalyst 32 is provided downstream, and since the amount of the odor component flowing into it is very small, it is completely oxidatively decomposed and removed. As described above, since the odor component is removed by the thermal decomposition and the oxidative decomposition in the device of the present embodiment, it is possible to prevent the generation of offensive odor outside the device.

As the garbage is dried as described above and the water content at the bottom of the lower drying container 5 is reduced, the temperature of the upper drying container 4 starts to gradually increase. When the temperature sensor 10 detects a predetermined temperature (for example, 150 ° C.), it is determined that the drying of the garbage is completed, and the burner 26 extinguishes, and the activity of the deodorizing catalyst 32 decreases. Stop to prevent odor components from being discharged outside the machine.

After the completion of the drying process, the operation of the circulation fan 14 and the exhaust fan 22 is continued. At this time, since the fire of the burner 26 has already been extinguished, the normal-temperature air flows as it is, and the equipment and the dried refuse are cooled. After this, the temperature sensor 1
When 0 detects a predetermined temperature (for example, 80 ° C.) as the completion of cooling, all the fans are stopped, and the process proceeds to a drying dust discharging step.

In the discharge step, the discharge motor 45 is driven to move the discharge piston 43 from inside the discharge cylinder 42 to the outside. When the discharge cylinder 42 is opened, the screw 17 with the saw blade rotates to the discharge side, whereby the dried garbage is scraped up by the screw 17 with the saw blade and falls naturally from the discharge cylinder 42 to the container 46 for the dry garbage. .

Since the discharge port 44 is provided at a high position, a container 46 for dry garbage having a large capacity can be used, and the labor for removing the dry garbage can be greatly reduced. In this case, the discharging process is performed for a certain period of time, and when all the motors stop at the same time as the certain period of time has elapsed, the device automatically stops.

[0033]

According to the present invention, the garbage held in the saw blade of the screw with a saw blade is cut or cut by a plurality of convex protrusions provided inside the lower drying container. The garbage that did not exist is surely torn by the discontinuous fixed blade provided higher than the projection height, so that the garbage put into the drying unit is finely crushed as a whole and widely comes into contact with high-temperature air. This has a remarkable effect that drying can be performed more efficiently and the drying time can be shortened.

In addition, since the fixed blade is discontinuous, the garbage fixed in the gap is easily separated from the inner surface of the container by the rotation of the saw blade provided on the screw with the saw blade, and the garbage is fixed on the front surface of the drying container. Therefore, the driving force of the stirring motor required for pulverization is reduced. Furthermore, since heat transfer from the bottom heating chamber to the garbage is not hindered, a high drying effect is obtained, and the locking of the screw with the saw blade is also prevented. This makes it possible to use a small motor for driving, etc., and thus has a remarkable effect that cost and weight can be reduced.
