Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to kitchen waste (garbage).
The present invention relates to an organic substance processing apparatus for decomposing an organic substance such as a microorganism by a microorganism, and more particularly to an organic substance processing apparatus in which the inside of a treatment tank is heated to a temperature suitable for activating microorganisms using hot water.

2. Description of the Related Art As an organic matter treating apparatus of this type of a microorganism decomposition treatment system, there is, for example, a garbage disposer described in JP-A-8-99076 (B09B 3/00).

In this garbage processing machine, a hot water circulation coil is arranged around a fermentation tank (treatment tank), and hot water is circulated in the coil to uniformly heat the inside of the tank and to use a temperature sensor. If the detected tank temperature is lower than the set temperature, the hot water generator (heat source unit) is driven to circulate hot water in the hot water circulation coil to raise the tank temperature to the set temperature and reach the set temperature. Then, the circulation of the hot water is stopped.

[0004]

However, in the arrangement in which the hot water circulating coil is arranged as described above, since the heat exchange effect by circulation of the hot water is used, the amount of hot water in the coil itself is small, and the heat capacity is inevitable. To be smaller,
When the temperature is low, the hot water supply time is long, and the running cost is high. In addition, since it is easy to heat and cool, the number of times of repeating the hot water supply by the heat source device and the stop thereof are increased, so that there is a high possibility that a problem occurs in the life of the heat source device.

[0005] The hot water circulation coil heats the inside of the tank only through a fermentation tank (treatment tank). However, if air is taken in to introduce outside air into the tank to activate microorganisms, When the outside air temperature is low in winter or the like, the temperature in the processing tank is greatly reduced by the intake air, and the processing capacity at low temperatures becomes insufficient.

Therefore, the present invention has been made to solve such a problem, and a sufficient heat capacity (amount of hot water) is secured by using a tank (hot water storage) type instead of a circulation type heater. It is possible to provide an organic matter processing apparatus that can reduce the running cost without increasing the hot water supply time even at a low temperature, and can increase the interval between the hot water supply and the stop to contribute to a longer life of the heat source unit. It is the purpose.

Further, it is possible to provide an organic material processing apparatus which can prevent the temperature in the processing tank from being lowered by the intake air even when the outside air temperature is low in winter or the like, and can obtain a sufficient processing capacity even at a low temperature. It is intended for.

Oxygen necessary for activating microorganisms is supplied into the processing tank 1 from a suction port 9 formed in the upper part of the processing tank 1.

As described above, the supply of hot water to the hot water heater tank 5 and the stop thereof are performed by the thermistor (not shown) for detecting the temperature of the hot water in the tank 5 and the thermistor 7 attached to the outlet side of the hot water discharge pipe 55. Based on the detected temperature, the control unit mounted on the control board 27 turns on / off the thermal valve 57 provided in the middle of the hot water supply pipe 56 and the external heat source unit.
By controlling the relay 58 that performs F control, the hot water temperature in the hot water heater tank 5 is controlled to be maintained at 40 ° C. to 70 ° C.

That is, when the temperature of the hot water in the hot water heater tank 5 drops to 40 ° C., the hot-air valve 57 is opened and the heat source unit is operated to start hot water supply.
When the temperature reaches 0 ° C., the thermal valve 57 is closed and the heat source unit is stopped to stop hot water supply. Further, when the detected temperature of the thermistor 7 attached to the outlet side of the drain pipe 55 cooled most by the outside air drops to 5 ° C., hot water is supplied only for a certain period of time in the same manner as described above to prevent the outlet pipe from freezing. It is planned.

As described above, in this embodiment, the hot water heater is not a circulation type but a tank (hot water storage) type,
A sufficient heat capacity (amount of hot water) can be secured, and the running cost can be suppressed without increasing the hot water supply time even at low temperatures. Also, since the heat capacity of the hot water heater tank 5 is large,
The interval between hot water supply and stoppage is increased, which can contribute to a longer life of the heat source device.

Further, since the lower surface 5b and the back surface 5c of the hot water heater tank 5 other than the contact surface 5a with the lower tank 3 are exposed to the air flow path for intake, even when the outside air temperature is low in winter or the like. Since the cold intake air can be warmed and the temperature in the processing tank 1 can be prevented from lowering due to the intake air, a sufficient processing capacity can be obtained even at a low temperature.

Further, since a sealing material 52 such as a heat-conductive gasket or a silicon-based caulking material is interposed on the contact surface 5a between the hot water heater tank 5 and the lower tank 3, the lower tank 3 made of resin is provided. Therefore, heat can be transferred from the hot water heater tank 5 to the processing tank 1 without waste.

Further, a hot water supply port 53 is provided on one lower side of the hot water heater tank 5 and a hot water outlet 54 is provided on the other upper side located on the diagonal line, so that the hot water in the tank 5 can be smoothly replaced. It can be carried out. In other words, when hot water is supplied from the upper side of the tank, the air in the tank is difficult to come out and the replacement of the hot water is hindered. However, the hot water is smoothly discharged together with the air by performing the above.

Further, the bottom surface of the tank 5 to which the intake air from the intake port 12 is blown is the coldest, and the hot water in the tank 5 is cooled and the specific gravity becomes heavy and collects on the lower side. . Also, the hot water supply temperature is 70 ° C to 80 ° C with respect to the hot water temperature in the tank (30 ° C to 40 ° C).
Since the specific gravity is high and the specific gravity is light, the natural hot water naturally convects upward and is easily mixed, so that the lower hot water supply and the upper hot water on the diagonal line thereof are most efficient.

It should be noted that, even if the hot water supply port 53 is not provided on the diagonal line as described above, if the hot water supply port 53 is provided on the lower side and the drainage port 54 is provided on the upper side, a certain effect can be obtained in the above points.
