Description

  TECHNICAL FIELD The present invention relates to a garbage processing apparatus for decomposing or drying garbage discharged from ordinary households or business establishments as a soot, and more particularly to a garbage processing apparatus capable of storing surplus contents in a processing tank.

  As processing methods of the garbage processing apparatus, a microbial decomposition method and a high-temperature drying processing method are generally known.

  The microbial decomposition treatment system is a method for decomposing garbage by the action of microorganisms. As a general garbage treatment device of this kind, a treatment tank into which garbage is charged and a treatment tank filled with the garbage are filled. And a heating means for heating the contents of the processing tank, a stirring means for stirring the contents of the processing tank, and a ventilation means for ventilating the inside of the processing tank. Here, the treatment material is made of a wood chip called a biochip carrying microorganisms. And the said heating means, agitation means, and a ventilation means operate | move, and as shown to (a) of FIG. 8, the moisture content of the content of a processing tank shall be 30-60%, and the temperature of the content of a processing tank shall be 20-60 degreeC. Maintaining within the range, the activity of microorganisms is increased thereby aerobically decomposing the garbage put into the treatment tank, and reducing the volume of garbage.

  In addition, the high-temperature drying treatment system heats the garbage at a high temperature of 100 ° C. or higher as shown in FIG. 8B. By this, the garbage with a moisture content of about 80% can be shortened to about 10% in a short time. The food waste is reduced by this drying process.

  In the above microbial decomposition treatment method, there is a problem that a decomposition odor such as ammonia is generated during the decomposition treatment, and in the high temperature drying treatment method, when the garbage is heated to 100 ° C. or more, the garbage is In recent years, new methods other than the above-mentioned microbial decomposition treatment method and high-temperature drying treatment method have been adopted. The used garbage processing apparatus is also proposed. This garbage disposal apparatus is provided with heating means, agitation means, and ventilation means, and maintains the temperature of the contents of the treatment tank at 90 ° C. or lower as shown in FIG. The moisture content of the product is controlled to 20% or less at which microorganisms cannot propagate, thereby suppressing the generation of microbial decomposition odor and burnt odor. This new type of garbage processing device has a high moisture content in the garbage immediately after it is put in, so it is filled with a treatment material consisting of a particulate or chip-like dispersion material with hygroscopicity. The moisture content of the garbage containing a large amount of water immediately after the addition is lowered by stirring the treatment material and the introduced garbage immediately after the addition.

  By the way, in the garbage processing apparatus as described above, the bulk of the contents of the processing tank increases with the repeated use of the apparatus, thereby maintaining the air permeability and temperature uniformity of the contents. Therefore, there is a problem that the processing efficiency of garbage is reduced. Therefore, conventionally, a garbage processing apparatus is used in which a storage tank in which surplus contents overflowed from the processing tank flows into the outside of the processing tank is provided separately from the processing tank. There are known a tank provided adjacent to the treatment tank (for example, Patent Document 1) and a tank provided at a position away from the treatment tank.

By the way, since the storage tank in the said patent document 1 is provided in the exterior of the processing tank, there exists a problem that a garbage processing apparatus will enlarge only the part of the storage tank provided separately from this processing tank. In addition to the treated garbage, untreated waste often flows into the surplus contents stored in this storage tank. However, as described above, the conventional storage tank is located outside the treatment tank. Since the storage tank provided outside the processing tank is not placed in the same environment as the inside of the processing tank, the untreated garbage stored in this storage tank is stored inside the processing tank. The garbage is not processed at the same time, and therefore, the garbage before treatment is spoiled inside the storage tank, causing problems such as generation of bad odors and insects.

  When processing garbage with the said garbage processing apparatus 1, a user opens the lid | cover 8, throws in garbage into the stirring area | region inside the processing tank 3 from the upper surface opening part 4 of the processing tank 3, and the cover 8 Then, the operation of the garbage disposal device 1 is started. When the operation is started, the control unit first stirs the contents 14 made of garbage and processing material in the stirring region for a predetermined time by the stirring means. Thereby, the content 14 is stirred uniformly and the moisture content of the content 14 falls by the moisture absorption effect | action of a processing material. After this, the control unit determines the content of the contents 14 periodically detected by the moisture content detection means and the temperature of the contents 14 periodically detected by the temperature detection means. By controlling each of them, the inside of the treatment tank 3 including the surplus content storage region and the stirring region is a raw material in which the temperature of the content 14 is 90 ° C. or less and the moisture content of the content 14 is 20% or less. The garbage is in a state suitable for drying treatment, and the garbage is dried in this environment. It is assumed that the stirring means during operation based on the moisture content and temperature of the contents 14 is operated intermittently.

  When the above-described treatment of garbage is repeated, the bulk of the contents 14 in the stirring area of the processing tank 3 increases. In this example, the contents 14 exceed a certain amount in the stirring area of the processing tank 3. When the agitation is performed with the agitation means, the excess content 30 that is the content 14 exceeding the certain amount overflows and flows into the storage unit 16, so that the processing tank 3 In this stirring region, the content 14 of a certain amount or more is not accumulated. Specifically, when agitation is performed by the agitation means, the surplus content 30 that is agitated by the rotational drive of the agitation blade 12 rises beyond the upper half downward rotation trajectory B1, and this elevation As shown in FIGS. 5 and 6, the surplus content 30 overflows and flows into the storage unit main body 24 from the inlet 17, and the surplus content 30 is stored in the storage unit main body 24. And among the surplus contents 30 stored in the storage unit main body 24, only the processing material and the garbage not larger than the particle size of the processing material pass through the plurality of sieve holes 28 and are in the stirring region of the processing tank 3. Returning to the contents 14, garbage having a particle size larger than that of the treatment material is stored in the storage unit body 24. And the said stirring is performed repeatedly and the volume of the content 14 of the processing tank 3 will be maintained by the fixed amount as shown in FIG. By storing the surplus contents 30 of the processing tank 3 in the storage unit main body 24 in this way, the contents 14 in the stirring region of the processing tank 3 do not accumulate beyond a certain amount, and the contents of the processing tank 3 It is possible to prevent a decrease in the processing efficiency of garbage due to an increase of 14.

  As described above, the storage unit 16 into which the surplus contents 30 overflowed from the stirring region of the processing tank 3 flows is disposed inside the processing tank 3, so that the processing is performed outside the processing tank 3 as shown in the conventional example. There is no need to provide a separate storage tank from the tank 3, and thus the garbage disposal apparatus 1 can be reduced in size. Moreover, although not only the garbage after a drying process but the garbage before a drying process may flow into the said storage part 16, the storage part 16 of this example is the inside of the processing tank 3, ie, the inside of the processing tank 3. The storage section 16 can be placed in an environment suitable for the drying treatment of garbage because it is arranged under the influence of the ventilation means for ventilating the water and the heating means for heating the contents 14 of the treatment tank 3. Thus, the unprocessed garbage stored in the storage unit 16 can be dried, and as a result, the unprocessed garbage stored in the storage unit 16 can be prevented from being spoiled. Moreover, among the surplus contents 30 stored in the storage unit 16 as described above, the processing material used for the treatment of garbage, or after the drying process that has been finely crushed and has a size equal to or smaller than the particle size of the processing material Since the garbage flows out of the plurality of sieve holes 28 and is returned to the stirring area of the treatment tank 3, the amount of treatment materials and dry garbage contained in the contents of the stirring area of the treatment tank 3 can be increased. This prevents a decline in the drying capacity of garbage.

  Further, in this case, the surplus content 30 flowing into the storage unit 16 has overflowed from the processing tank 3 and is not pushed into the stirrer blade 12 to flow in. It is possible to prevent sticking, and the storage unit 16 can be easily maintained. Further, since the storage section 16 is disposed below the upper end a of the rotation locus circle B, the side of the side wall 7c raised above the contents 14 on the side wall 7d side of the processing tank 3 when the stirring blade 12 is driven to rotate. The contents 14 can be smoothly introduced into the storage unit 16. Further, by providing the storage unit 16 at such a position, there is an effect that the storage unit 16 does not get in the way when the garbage is introduced from the upper surface opening 4 of the treatment tank 3. In addition, by providing a heater for heating the surplus contents stored in the storage unit 16 for heating the surplus contents, the garbage stored in the storage unit 16 before the drying process is further dried. Can do.

  Moreover, as shown in FIG. 7, the storage part main body 24 of the storage part 16 is obstruct | occluded by the said bottom wall part 25 and side wall part 26a-26d, and the upper opening formed by these bottom wall part 25 and side wall part 26a-26d. It is also preferable to form a plurality of inflow ports 34 formed with a plate-like top wall portion 33 and having a predetermined opening diameter larger than the sieve hole 28 in the top wall portion 33. Specifically, the opening diameter of each inflow port 34 is formed to be about 10 to 30 mm. In the illustrated example, each inlet 34 is formed by a slit 35 provided in the ceiling wall 33, but the plurality of inlets 34 may be formed by forming the ceiling wall 33 in a mesh shape. And In this way, by forming a plurality of inflow ports 34 having an opening diameter larger than that of the sieve hole 28, the surplus contents 30 larger than the inflow port 34, that is, the raw material having a large bulk in an undried state immediately after being charged. It is possible to prevent dust and the like from flowing into the storage unit main body 24. As a result, the storage unit main body 24 stores only garbage that is larger than the sieve hole 28 and smaller than the inflow port 34 and is not easily spoiled. Can do. The top wall 33 is pivotally attached to the upper end of the storage section 16, so that the top wall 33 can be opened and the storage section 16 can be easily cleaned.
