Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a waste treatment apparatus that efficiently and intensively decomposes waste (for example, garbage such as leftover food) using the power of microorganisms and the like, and more particularly, an input lid or a scraping lid in the waste treatment apparatus It is about.
[0002]
[Prior art]
In recent years, waste processing apparatuses using the power of microorganisms or the like are known. This waste treatment apparatus is filled with a base material for decomposing waste in the treatment tank, and the waste is thrown into the treatment tank from the inlet provided in the treatment tank by opening the input lid, Waste is decomposed by the action of microorganisms that inhabit the substrate.
[0003]
In the waste processing apparatus, a packing material is provided between the input lid and the peripheral edge of the input port so that the processing tank having the input port is airtight when the input lid is closed.
[0004]
[Problems to be solved by the invention]
By the way, waste juice that spills when waste such as garbage is thrown into the treatment tank tends to adhere to the packing material contact surface at the peripheral edge of the inlet. When the soup is closed for a while after closing the charging lid, it acts as if it were an adhesive, causing the peripheral edge of the charging port to adhere to the packing material. For this reason, when the packing material is integrally provided on the charging lid, a large amount of labor is required to open the charging lid, and in the worst case, the charging lid cannot be opened.
[0005]
Further, the packing material is generally made of a flexible rubber material or the like, but is compressed or crushed in response to the weight of the charging lid after long-term use. Therefore, there is a case where the elasticity is lost and plastic deformation may occur, and there is a problem that the inherent flexibility of the packing is lost and the airtightness of the processing tank is lost.
[0006]
In addition, the charging lid also serves as an exterior member of the processing device main body, and the above deformation of the packing material causes a positional shift when the charging lid is closed, resulting in unscheduled gaps and steps with other exterior members. There was also a problem that the appearance of the device body was unsightly.
[0007]
Similarly, at the scraping port of the waste processing apparatus, a packing material is interposed between the peripheral edge of the scraping port and the scraping lid so that the processing object in the processing tank does not leak out. We must ensure sex. However, this packing material is also generally made of a flexible rubber material or the like, and is compressed or crushed by receiving the tightening force of the scraped lid after long-term use. Thus, there is a case where plasticity is lost due to loss of elasticity, and here again, there is a problem that the inherent flexibility of the packing is lost and the airtightness of the treatment tank is lost.
[0008]
The present invention has been made in view of the above-described problems of the conventional example, and an object of the present invention is to improve the sticking phenomenon of the packing material due to waste juice in a waste treatment apparatus. At least one of preventing the deformation of the packing material and maintaining the airtightness of the processing tank, eliminating unsightly gaps and steps as an exterior member, maintaining a beautiful appearance, and mitigating impact noise when closing the closing lid Is to achieve that.

[0024]
Next, the operation and operation of the waste disposal apparatus 1 configured as described above will be described.
As shown in FIG. 1, the waste treatment apparatus 1 includes a waste treatment tank 3 having a waste input port 2 in the main body of the treatment apparatus. The treatment tank 3 has a stirring shaft with a stirring nail (not shown in the drawing because it is not directly related to the present invention, which is complicated), and a base material (not shown for the same reason) is contained therein. ing.
[0025]
The base material is made of sawdust, the main component of which is hard to biodegrade, each of which is porous, has water absorption and voids, has a complicated particle shape, and large voids are formed between the particles. Yes. Oxygen can be supplied to the treated organism by this void, and the efficiency of waste decomposition treatment is improved. In the present embodiment, the treatment organisms that decompose the waste in the mixture of the waste and the base material are aerobic microorganisms and fungi.
[0026]
Waste disposal is performed as follows. The input lid 4 is opened and waste is input into the processing tank 3 from the input port 2 provided in the processing tank 3. Along with this, the stirring shaft with the stirring claw is rotated to start stirring of the waste, and the thrown-in waste is finely crushed and mixed with the base material evenly. Thereby, the waste is decomposed into moisture and carbon dioxide gas by the action of microorganisms that live in the base material, and the gas is processed into the treatment tank 3 through the exhaust port 19 by an exhaust fan (not shown for the same reason as above). To the outside.
[0027]
On the other hand, as the waste treatment operation continues, the hard-to-decompose materials (plastic bags, disposable chopsticks, shells, etc.) that are put together with the residue and organic matter after the decomposition treatment accumulate on the base material inside the treatment tank 3 and inhabit the microorganisms. The environment gradually deteriorates, leading to a decrease in decomposition processing capacity. From this, the base material inside the processing tank 3 is taken out from the scraping port 12 at an appropriate cycle (for example, once every two months) and replaced with a new base material.
[0028]
In the waste treatment apparatus 1 as described above, the charging lid stopper and the scraping lid stopper that form the core of the present invention will be described.
[0029]
A recess 9 to which the charging lid 4 is attached is provided on the upper surface of the processing apparatus main body, and the charging port 2 is provided in the recess 9. The packing material 6 attached to the charging lid 4 is brought into contact with the entire periphery of the peripheral edge of the charging port 2. The packing material 6 is attached so as to be integrated with the charging lid 4 by being sandwiched between packing mounting frames 7 formed on the inner surface of the charging lid 4.
[0030]
A pair of hinges 8a and 8b are attached to one end of the charging lid 4 (on the back side of the processing apparatus main body), and the charging lid 4 is attached to the processing apparatus main body through the hinges 8a and 8b so as to be freely opened and closed. A pair of stoppers 5a and 5b are attached to the left and right at one end of the charging lid 4 opposite to the attachment side of the hinges 8a and 8b (front side of the processing apparatus main body). Further, the stoppers 5a and 5b are attached to the outside of the packing material 6 that is attached to the inner surface of the charging lid 4 and are isolated from moisture and carbon dioxide generated from the processing tank 3, and are made of a material having elasticity such as rubber. The stopper itself is made not to be deteriorated by moisture or carbon dioxide.
[0031]
As shown in FIG. 3, the packing material 6 includes a trim portion 6 b inserted into the packing mounting frame 7 of the charging lid 4 and a hollow portion 6 a pressed against the peripheral edge of the charging port 2, and is made of an elastic material such as rubber. It is made with. The height A of the packing material 6 from the inner surface of the charging lid 4 is set to about 125% with respect to the height B of the stoppers 5a and 5b. The intention is as follows. When the charging lid 4 is closed, the hollow portion 6a of the packing material 6 is crushed to the height B of the stoppers 5a and 5b to ensure airtightness with the peripheral edge of the charging port 2, but the packing material 6 at that time The amount of deflection is about 25%. This amount is a deformation within the elastic limit of a general rubber material, and the packing material 6 can maintain flexibility without being plastically deformed even when used for a long period of time. Can be maintained. Further, if the amount of bending is such a degree, the repulsive force of the packing material 6 is small, the pressing force to the peripheral edge of the charging port 2 is weak, and the packing material 6 and the peripheral edge of the charging port 2 are less likely to stick. .
[0032]
If a packing material made of chemically stable silicone rubber or the like is used as the packing material 6, the fixing phenomenon with the peripheral edge of the inlet 2 can be improved, but the silicone rubber is expensive. Therefore, in this embodiment, a packing material using EPDM rubber (ethylene / propylene rubber) which is inexpensive and excellent in chemical resistance is used. Nevertheless, by providing the stoppers 5a and 5b, which are the gist of the present invention, the fixing phenomenon can be improved more reliably.
[0033]
If the amount of bending of the packing material 6 is set to be small, the packing material 4 may be deformed or warped, or the packing material 6 contact surface at the periphery of the charging port 2 may have poor flatness. A gap is easily generated between 6 and the peripheral edge of the charging port 2, and the airtightness of the processing tank 3 cannot be ensured. For this phenomenon, it is important that the peripheral edge of the charging port 2 and the charging lid 4 are accurately spaced at a predetermined interval and the amount of flexure of the packing material 6 is determined to be constant. Therefore, the stoppers 5a and 5b are It is preferable to arrange one each on the side facing the hinges 8a and 8b toward the input lid 4 on the left and right.
[0034]
The stoppers 5a and 5b may be disposed on the input port 2 side. However, if there is a protrusion such as the stoppers 5a and 5b at the peripheral edge of the input port 2 when the waste is input to the treatment tank 3, the wastes are disposed. It interferes with the input work. In addition, waste spills into the peripheral edge of the inlet 2 and the peripheral edge of the inlet 2 is easily soiled and needs to be cleaned frequently. At this time, protrusions such as stoppers 5a and 5b are formed on the inlet 2 side. If there is something, it will interfere with the work. Therefore, the stoppers 5a and 5b of the present invention are preferably attached to the charging lid 4 side.
[0035]
Further, as shown in FIG. 6, the six-sided exterior portion 10 surrounding the processing tank 3 is made by combining metal sheet processing members such as metal. The outer plate 10R and the left upper surface outer plate 10L are divided into three parts. These upper surface exterior parts are connected continuously, and the one that is a flat surface as if constituted by a single plate looks better in appearance. For this purpose, the right upper surface exterior plate 10R, the left upper surface exterior plate 10L, and the insertion lid 4 are attached to the peripheral edge of the insertion port 2 at a predetermined interval with high accuracy so that there is no step between them. It is desirable that In addition, in order to maintain a predetermined interval with high accuracy even when used for a long period of time, the stoppers 5a and 5b are arranged on the side facing the hinges 8a and 8b and further toward the charging lid 4 as in the present embodiment. It is better to place one on each side.
[0036]
Next, the scraping lid stopper will be described. As described above, the base material has a lifetime, and as the waste treatment operation continues, the habitat of microorganisms in the base material gradually deteriorates, leading to a decrease in decomposition treatment capacity. It is necessary to take out the base material at an appropriate cycle and replace it with a new base material. At the time of replacement of the base material, as shown in FIG. 1, first, the scraping port exterior cover 11 of the main body exterior portion 10 is removed, the scraping cover 13 is opened, and the used base material is treated with a scoop or the like from the scraping port 12. The tank 3 is scraped from the inside.
[0037]
As shown in FIG. 4, the packing material 14 of the scraping lid 13 also includes a trim portion 14 b to be inserted into the packing mounting frame 15 of the scraping lid 13 and a hollow portion 14 a that presses against the peripheral portion of the scraping port 12 of the processing tank 3. Made of elastic material such as rubber. The height C of the packing material 14 from the inner surface of the scraping lid 13 is also set to about 125% with respect to the height D of the stoppers 16a and 16b. This is the same as the intention described in the description of 6. That is, when the scraping lid 13 is closed, the hollow portion 14a of the packing material 14 is crushed to the height D of the stoppers 16a and 16b to ensure airtightness with the peripheral portion of the scraping opening 12. The amount of bending of 14 is 25%. This amount is a deformation within the elastic limit of a general rubber material, and the packing material 14 can maintain flexibility without being plastically deformed even when used for a long period of time. If the amount of bending can be maintained, the repulsive force of the packing material 14 is small, the pressing force to the peripheral portion of the scraping port 12 is weak, and the packing material 14 and the peripheral portion of the scraping port 12 are fixed. It becomes difficult.
[0038]
On the other hand, if the amount of deflection of the packing material 14 is set to be small, the packing material 14 may be deformed or warped, or the flatness of the contact surface of the packing material 14 at the periphery of the scraping port 12 may be poor. 14 and the peripheral edge of the scraping port 12 are easily generated, and the airtightness of the processing tank 3 cannot be ensured. As described above, with respect to this phenomenon, it is important that the peripheral portion of the scraping opening 12 and the scraping lid 13 are accurately spaced at a predetermined interval and the amount of deflection of the packing material 14 is determined to be constant. 16a and 16b are preferably arranged on the side facing the hinge 17 one by one on the left and right sides toward the scraping lid 13.
[0039]
In the above embodiment, the charging lid stoppers 5a and 5b and the scraping lid stoppers 16a and 16b are made of an elastic material such as rubber. Especially when the charging lid stoppers 5a and 5b are closed, the charging lid 4 is closed. Even if the charging lid 4 falls down vigorously, the impact sound can be mitigated.
[0040]
