Abstract

PROBLEM TO BE SOLVED: To properly keep water content of a microorganism carrier by condensing evaporated steam from a treatment tank to store condensed water in a tank and detecting the water content of the microorganism carrier in the treatment tank and sprinkling the water of the tank over the inside of the treatment tank when the water content becomes a predetermined value or less. SOLUTION: A microorganism carrier is housed in a treatment tank 1 and garbage is charged in the tank 1 to close a lid 6. A stirring motor 10, a planar heater 11 and an exhaust fan 14 are operated by a microcomputer to start garbage treatment. Steam generated from garbage is introduced into an exhaust cylinder 15 along with exhaust gas by the exhaust fan 14 and condensed by a condensing plate 16 to be stored in a water tank 17. A water content sensor 12 measures, water content of matter to be treated to compare the same with water content suitable for activating bacteria. If the measured value is equal to or less than the water content, a solenoid valve 21 is opened to sprinkle the water in the water tank 17. By this constitution, the water content of matter to be treated can be held to a good state by putting water in garbage to practical use without taking labor of a user.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic substance processing apparatus for decomposing organic substances such as garbage by microorganisms.

[0002]

2. Description of the Related Art An organic substance processing apparatus for decomposing organic substances such as garbage by microorganisms cultured on a carrier has been put to practical use as a garbage processing machine. In this organic matter treatment device, the activation of aerobic microorganisms in the treatment tank is promoted,
In order to accelerate the growth and perform the efficient treatment, it is necessary to always keep the temperature inside the tank at an appropriate level. For the heat insulation in the processing tank, for example, a planar heater using a nichrome wire is used,
By operating a controller in accordance with a signal from a temperature sensor for detecting the temperature in the bath and controlling on / off of the planar heater, the temperature in the bath is maintained in a predetermined temperature range. At this time, the moisture evaporated from the organic matter such as the heated garbage is directly discharged to the outside air.

[0003] In addition to maintaining the temperature appropriately, the water content of a mixture of a carrier containing aerobic microorganisms and an organic substance (hereinafter also referred to as an object to be treated) for efficient treatment of the organic substance is determined. It is required to keep it properly. Properly maintaining the water content can promote the growth of microorganisms in the carrier, but once dried, it takes time for the dried microorganism carrier to be in a state of active decomposition again.

[0004]

As described above, in the conventional apparatus, the water discharged from the organic matter such as garbage is released to the outside air as water vapor. Therefore, when the microorganism carrier has dried, it has been quite troublesome to pump water and put it into the treatment tank. In addition, water can be stored in a separately provided hydration tank, but there is a possibility that the water will be in a dry state due to forgetting to put it in. Once dried, it takes time to start up again. Also,
Although it is possible to draw tap water, there is a problem that water works are required when the apparatus is installed.

Therefore, the present invention has been made to solve such problems, and effectively utilizes water generated from organic substances such as garbage so that a microorganism carrier can be used without any trouble and cost for a user. It is an object of the present invention to provide an organic matter treating apparatus capable of appropriately maintaining the water content of the organic matter.

[0006]

Means for Solving the Problems To achieve the above object, an object of the present invention is to introduce an organic substance such as garbage into a treatment tank containing a microorganism carrier, stir the carrier and the organic substance, and mix An organic matter treating apparatus for decomposing the organic matter by microorganisms cultured in the condensing means for condensing water vapor vaporized from the treatment tank; and storing water condensed by the condensing means on the upper side of the treatment tank.

[0007] Further, the present invention provides an organic substance such as garbage in a treatment tank containing a microorganism carrier, agitates the carrier and the organic substance, and decomposes the organic substance by microorganisms cultured in the carrier. In the organic matter treating apparatus, a condensing unit for condensing water vapor vaporized from the processing tank, a tank for storing water condensed by the condensing unit, and a water content detecting unit for detecting a water content of the carrier in the processing tank.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front sectional view of a garbage disposer as an embodiment of the organic matter treating apparatus according to the present invention, FIG. 2 is a side sectional view thereof, and FIG. 3 is a top view seen from a garbage inlet. .

This garbage processing machine has a processing tank 1 having a substantially U-shaped side section and a rectangular cross section. The treatment tank 1 is housed in a case 2, and is opened on the upper surface side of the case 2 in correspondence with the upper opening of the treatment tank 1, and a substance to be treated 3 such as a microorganism carrier or garbage is charged. Input port 4 for
Are formed. A lid 6 is provided on the upper surface side of the case 2 so as to be freely opened and closed by a hinge 5.

A stirring shaft 8 provided with a number of stirring blades 7 at substantially equal intervals between both side walls is rotatably provided at a lower side in the processing tank 1. Both ends of the stirring shaft 8 are supported by bearings, and one end of the shaft is connected to a stirring motor 10 via a power transmission belt 9 so as to be driven to rotate. The stirring motor 10 is operated, for example, when garbage is put into the processing tank 1 and the lid 6 is closed, and every 30 minutes to 1 hour thereafter.
Each time, and when water is sprayed due to a decrease in the water content, which will be described later, the rotation is performed.

A planar heater 11 is mounted on the outer surface of the semicircular lower portion of the processing tank 1, and is put into the processing tank 1 by a thermistor or the like built in the planar heater 11. 3 to be treated 3 consisting of organic carrier and garbage
The temperature is controlled to be maintained at a temperature of about 5 ° C to 60 ° C.

On the other hand, in the lower part of the processing tank 1,
A moisture content sensor 12 for detecting the moisture content of the workpiece 3 is provided on a side wall that is always buried in the workpiece. The water content sensor 12 has, for example, two electrodes, and detects the water content by detecting the capacitance of the workpiece 3 between the electrodes.

An exhaust hole 13 is formed in one upper side wall of the processing tank 1, and an exhaust fan 14 is formed outside the exhaust hole 13.
Is attached. The exhaust fan 14 is always driven when the present apparatus is operated, and the outside air sucked from the gap between the case 2 and the lid 6 is supplied into the processing tank 1 by the drive of the exhaust fan 14. Thus, fresh oxygen is always supplied to the aerobic microorganisms cultured on the carrier, and exhaust gas containing water vapor evaporated from garbage by being heated and maintained by the planar heater 11 is discharged.

The exhaust fan 14 and the exhaust fan 14
A condensing plate 16 is provided between the exhaust pipe 15 and the exhaust pipe 15 for discharging the exhaust gas from the exhaust pipe to the outside. The exhaust gas containing a large amount of water vapor hits the condensing plate 16 and is cooled to condense the water vapor, adheres to the condensing plate 16 as water droplets, and falls. Immediately below the condensing plate 16, the condensing plate 16
Water tank 17 for storing water drops falling from
Are formed.

On the upper side of the side wall of the water storage tank 17, the water W accumulated in the water storage tank 17 becomes full and exhaust holes 13
An overflow pipe 17 is provided to prevent the gas from flowing into the processing tank 1 or flowing out of the exhaust pipe 15 to the outside. The tip of the overflow pipe 18 is the case 2
It is inserted into a large capacity drainage tank 19 placed on the lower side of the inside.

On the other hand, a water supply port 20 is provided at the bottom of the water storage tank 17.
A sprinkling pipe 22 is attached through the first spout 1. The water sprinkling pipe 22 has a number of small water sprinkling holes 23 on the lower surface side thereof. As shown in FIG. 1 inner wall). In this embodiment, since the watering point is limited and the water does not easily spread to the whole of the workpiece 3 in such a piping, the stirring motor 10 is driven to rotate the stirring blade 7 at the time of watering, and the workpiece is By stirring the mixture 3, the water is distributed to the entire treatment object 3.

The solenoid valve 21 opens and closes according to the detection result of the water content sensor 12 described above. When the detected water content falls below a predetermined value, the solenoid valve 21 is opened and water from the water storage tank 17 is scattered. The water is supplied to the water pipe 22 and sprinkled into the processing tank 1. In addition, conventionally, the stirring motor 10
, A sheet heater 11, an exhaust fan 14, and the like, an opening / closing detection sensor for the lid 6, a timer, and a thermistor (neither is shown).
Since a microcomputer for controlling the electromagnetic valve 21 and the stirring motor 10 based on the detection output of the moisture content sensor 12 is provided, the microcomputer can be easily realized.

In the above configuration, when using the garbage disposer, first, a certain amount of the microorganism carrier is put into the treatment tank 1. When processing the garbage, the lid 6 is opened and the garbage is put into the processing tank 1 through the input port 4 and the lid 6 is opened.
Close.

When the lid 6 is closed, a lid opening / closing sensor (not shown) detects this, and based on the output, the microcomputer operates the stirring motor 10, the sheet heater 11 and the exhaust fan 1.
4 is energized.

When the stirring motor 10 and the planar heater 11 are energized, the stirring blade 7 rotates to mix the microorganism carrier and the garbage, and the temperature in the treatment tank 1 is optimized for activating aerobic microorganisms. While maintaining the range, the garbage is decomposed by aerobic microorganisms cultured on the carrier and composted. At this time, the moisture contained in the garbage evaporates and is gradually dried.

Further, when the exhaust fan 14 is energized, the fan 14 rotates to take in outside air into the treatment tank 1 to supply oxygen necessary for activating the aerobic microorganisms and to remove water contained in the garbage. Promotes vaporization.

The air containing a large amount of water vapor, which is obtained by evaporating water contained in the garbage, is exhausted from the processing tank 1 as an exhaust gas through an exhaust hole 13 provided at an upper portion of the side wall of the processing tank 1 by an exhaust fan 14. . The exhaust gas discharged by the exhaust fan 14 tries to exit the apparatus through the exhaust pipe 15, but a condensing plate 16 is provided between the exhaust fan 14 and the exhaust pipe 15.
Therefore, the exhaust gas blown out from the exhaust fan 14 hits the condenser plate 16 and is cooled, so that a large amount of water vapor is condensed, adheres as water droplets, and falls into the water storage tank 17.

As described above, in the treatment tank 1, the moisture content of the article 3 to be treated gradually decreases due to the heat insulation by the sheet heater 11 and the decomposition of garbage by microorganisms.
On the other hand, water condensed from the exhaust gas gradually accumulates in the water storage tank 17.

When the moisture content of the object 3 detected by the moisture content sensor 12 falls below a predetermined value (for example, the lower limit of the activation range) within a range suitable for activating microorganisms, The electromagnetic valve 21 is opened and the stirring motor 10 is driven by the control of the microcomputer that has detected this. When the solenoid valve 21 is opened, the water collected in the water storage tank 17 is supplied to the water sprinkling pipe 22 by natural fall, and is sprinkled onto the workpiece 3 from the many water sprinkling holes 23 provided on the lower surface thereof. . Further, when the stirring motor 10 is driven, the stirring blade 7 rotates and the object 3
Are mixed, so that the water sprinkled from the sprinkling pipe 22 spreads over the entire treatment object 3.

When watering is performed in this manner, the water content of the object 3 gradually increases, and reaches a predetermined value (for example, the upper limit of the activation range) within a range suitable for activating microorganisms. Upon reaching this, the solenoid valve 21 is closed by the control of the microcomputer that detects this, and the driving of the stirring motor 10 is also stopped. The above operation is repeatedly performed as necessary based on the output of the moisture content sensor 12, whereby the microorganism carrier can be prevented from being in a dry state, and its moisture content is within a range suitable for activating the microorganism. Is always kept. In addition, in addition to the above, the agitating motor 10 is provided for two times each when garbage is put into the processing tank 1 and the lid 6 is closed, and once every 30 minutes to one hour thereafter.
It is driven to rotate for about a minute.

As described above, according to the present embodiment, the moisture content of the microorganism carrier can be always maintained in a good state without any trouble for the user, and the moisture originally contained in the garbage can be reduced. Since it is used effectively, there is also a water saving effect, and no water supply work is required. Further, since the water storage tank 17 is provided at the upper portion to utilize the head and water can be sprayed only by opening and closing the solenoid valve 21, it can be realized with a simple configuration.

Next, a second embodiment will be described.

In this embodiment, the water storage tank 17 is not provided as in the above embodiment, and the water drops falling from the condensing plate 16 are directly stored in the drainage tank 19. Then, a pipe 24 and a pump 25 for pumping up the water W accumulated in the drainage tank 19 are provided, and the water pumped up by the pump 25 is sprinkled onto the workpiece 3 by the sprinkling pipe 22 similar to the above embodiment. Make up. Pump 2 above
5 is a predetermined value (for example, activation range) in which the water content of the object 3 detected by the water content sensor 12 is predetermined within a range suitable for microbial activation, similarly to the solenoid valve 21 of the embodiment. Below the lower limit), it is driven by the control of the microcomputer that detects it, and similarly, when it reaches a predetermined value (for example, the upper limit of the activation range) within a range suitable for microbial activation, Is stopped by the control of the microcomputer that has detected the error. Other operations are the same as those in the above embodiment.

Therefore, in the present embodiment, a water level sensor 26 is provided on the upper side wall of the water storage tank 17. In addition, the condensing plate 16a in the present embodiment includes:
For example, a solenoid may be in a state of hanging down so as to block exhaust gas from the exhaust fan 14 as shown in FIG. 5 and in a state of being lifted up so as not to block exhaust gas from the exhaust fan 14 as shown in FIG. It is configured to be rotatable by driving. Then, according to the detection result of the water level sensor 26, while the water level of the water storage tank 17 is low as shown in FIG. 5, the condenser plate 16a is activated, and the water level of the water storage tank 17 becomes high as shown in FIG. When the water level sensor 26 is activated, the solenoid of the condensing plate 16a is driven by the control of the microcomputer that detects this, and the condensing plate 16a
Is rotated so as to stick to the upper surface, so that the condensation action does not work. As a result, the water storage tank 17 does not overflow, so that a drain tank is not required,
Also, it is not necessary to dispose of excess water. Other functions and effects are the same as those of the above-described embodiment.
