Description

Organic material processing device

The present invention relates to an organic matter treatment apparatus for decomposing organic matter such as kitchen waste by the action of microorganisms.

As one method for treating organic matters such as kitchen waste (fresh garbage) generated in kitchens of general households and restaurants, there is a method using decomposition by microorganisms. In the organic material treatment apparatus according to this method, an inlet is provided in an upper portion of a processing tank for storing microorganisms for decomposing organic matter and carriers for culturing microorganisms (wood chips, sawdust, activated carbon, etc.), and stirring means therein. The organic material introduced into the treatment tank via the above-described inlet is mixed with the carrier by the operation of the stirring means, and the organic material is decomposed by the activity of the microorganisms living in the carrier.

The decomposition of organic matter in the treatment tank is carried out in the same manner as the decomposition of organic matter which is routinely performed in nature, and the organic matter introduced into the treatment tank is decomposed into gas and water mainly containing carbon dioxide gas, leaving a small amount of residue. do. In order to effectively perform this decomposition, it is important to supply an appropriate amount of air (oxygen) in a carrier containing an appropriate amount of water and maintained at an appropriate temperature, and to maintain the inside of the carrier in an environment suitable for the activity of microorganisms.

Here, conventionally, a ventilation means and a heating means are provided, and the external water is discharged out of the treatment tank and the external air is supplied to the treatment tank at the same time by discharging the gas containing mainly the excess moisture and carbon dioxide gas generated by the decomposition treatment by the operation of the ventilation means. While maintaining the air volume and water content in the treatment tank as appropriate, while maintaining the inside of the treatment tank at the proper temperature by the operation of the heating means, and again by stirring the carrier at a suitable interval by the operation of the stirring means to air in the inside of the carrier At the same time, an operation is performed in which a gas containing mainly water and carbon dioxide gas generated by decomposition is discharged to maintain the environment inside the processing tank.

In this kind of organic matter treatment apparatus, with the continuation of the operation performed as described above, residues after decomposition treatment and hardly decomposed products (bones, shells, etc.) introduced with the organic matter are accumulated in the carrier inside the treatment tank, Due to the gradual deterioration of the microbial habitat environment resulting in a decrease in processing capacity, it is necessary to take out the carrier in the treatment tank at a suitable interval and replace it with a new carrier.

In the exchange of such a carrier, it is necessary to facilitate the removal of the carrier in the processing tank, and is conventionally disclosed in Japanese Patent Application Laid-Open No. 7-136627 (B09B 3/00) and Japanese Patent Laid-Open No. 7-222967 ( B09B 3/00), as shown in the lower part of the treatment tank, the outlet for the carrier discharge can be opened and closed freely by the shutter, and in the case of changing the carrier, the shutter is removed and the outlet is opened. Is adopted to take out the carrier in the processing tank to the outside.

The inside of the treatment tank is maintained at a suitable temperature by the heating operation of the heating means, and in order to facilitate the exchange of carriers, the outlet for taking out the carrier is directly exposed to the outside, particularly in the cold air, through the outlet. There is a fear that the inside of the tank is cooled to increase the load of the heating means and at the same time, the organic matter treatment efficiency is lowered.

Here, Japanese Unexamined Patent Application Publication No. 7-222967 discloses that the front plate of the outer case is free to be attached and detached, and when replacing the carrier, the front plate of the treatment tank is removed by exposing the entire front portion of the treatment tank to release the shutter. It is removed to open the outlet and to take out the carrier inside the treatment tank, while during operation, the front plate of the treatment tank is covered by the front plate to avoid direct contact between the treatment tank and the outside air.

However, attaching and detaching the front plate of the outer case and attaching and detaching the shutter to block the outlet port need to be carried out by attachment means such as screwing, and there is a problem that a great deal of effort is required when replacing the carrier.

In addition, when the shutter is closed to remove the carrier after the carrier is taken out, the carrier stirred inside the processing tank leaks into the outer case from the gap of the outlet, and the organic matter contained in the carrier proceeds in the outer case, causing odor. There is a fear of discomfort to the user.

In addition, when the front plate of the outer case is incompletely mounted, the thermal insulation effect of the treatment tank is lowered, thereby increasing the load of the heating means for heating the inside of the treatment tank and reducing the organic matter treatment efficiency.

In addition, when the front plate of the shutter and the outer case are incompletely mounted, there is a possibility that insects such as flies may enter the treatment tank and breed in the treatment tank from the gap between the front plate and the outlet of the outer case.

In addition, Japanese Patent Application Laid-Open No. 7-136627 is configured to freely block and attach the ejection hole through the outer cover (lid of lid to be removed) through the outlet port installed in the front lower part of the outer case containing the processing tank. At the same time, the safety switch is turned on only when either the shutter or the outer cover is mounted, and the agitator can be driven when the switch is in the ON position. By removing the cover and the shutter and opening the outlet and the outlet, the carrier in the processing tank is taken out, and during operation, the opening is covered by the external cover to avoid direct contact between the processing tank and the outside air.

However, the purpose is to avoid the risk of inadvertent operation of the stirring means when removing the carrier by opening the outlet, and the organic material processing apparatus can be operated if either the shutter or the outer cover is mounted. For example, if the exterior cover is mounted but the shutter is not mounted, the carrier which is stirred inside the processing tank leaks into the exterior case from the gap of the outlet, and the organic matter contained in the carrier proceeds in the exterior case, causing discomfort caused by the odor. There is a risk to give the user. In addition, when the shutter is mounted but the outer cover is not mounted, the processing tank is cooled through the ejection hole which is not equipped with the outer cover, especially in a cold air, so that the organic matter treatment efficiency decreases and the inside of the processing tank is heated. There is a fear that the load on the heating means increases.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is possible to reduce the effort required for attaching and detaching the shutter to the outlet of the carrier installed in the treatment tank and attaching and detaching the exterior cover to the ejection hole installed in the exterior case through the outlet. An object of the present invention is to provide an organic material treating apparatus which can easily exchange a carrier.

As a result, the outlet 17 is closed freely. A discharge chute 23 inclined toward the front is formed at the bottom of the exterior case 2 facing the discharge port 17 from the lower side, and the opening and closing is freely closed by the exterior cover 6 at the front of the discharge chute 23. The take-out hole 25 of the carrier A is formed. In addition, the outer surface of the bottom surface of the processing tank 1 is mounted on the rear surface, mainly on the rear side, avoiding the formation area of the outlet opening 17 formed on the front surface of the sheet heater heater H for the internal heating.

When organic matters such as kitchen waste are introduced into the treatment tank 1 by opening the upper lid 21 to the organic matter treatment device configured as described above, the forward and reverse rotation of the stirring body 4 by the forward and backward driving of the stirring motor M is performed. It is enclosed in the carrier (A) by the microorganisms and decomposed by the action of microorganisms inhabiting the carrier (A). In the meantime, the electric current to the heater H, the drive of the ventilation fan, and the drive of the stirring motor M are controlled by the operation of the operation control unit configured on the control board 3. The energization control to the heater H is performed to maintain the internal temperature of the treatment tank 1 at an appropriate temperature, and the drive control of the ventilation fan is generated by organic decomposition while supplying an appropriate amount of air to the interior of the treatment tank 1. In order to discharge the moisture and gas to the outside of the processing tank (1), the drive control of the stirring motor (M) is to stir the carrier (A) inside the processing tank (1) regularly to blow air in the carrier (A) and At the same time, it is carried out to release water and gas generated in the carrier A. By performing such a control, the inside of the processing tank 1 is maintained in an environment suitable for the action of microorganisms, and the organic matter is decomposed into gas and water mainly containing carbon dioxide gas, leaving a small amount of residue.

On the other hand, with the continuation of the above operation, in the carrier (A) inside the processing tank (1), since the residue after decomposition treatment and the hardly decomposed products (plastic bags, chopsticks, shells) introduced together with the organic matter are accumulated, The deterioration of the habitat environment leads to a deterioration of the organic matter treating ability, so that the deteriorated carrier (A) needs to be replaced.

In addition, the tapered edge 51a is formed also in the front part of the side plate 51 of the reverse side which is not shown in FIG.

7 is an external perspective view of the exterior cover 6. This figure shows the same side as FIG. 5, ie, the side which becomes backward in the mounting state shown in FIG. As shown in the figure, the exterior cover 6 is compressed with a pair of compression plates 61 and 61 protruding from both sides of the front plate 60 and the rear surface of the front plate 60 covering the ejection holes 25. A pair of upper wedges 62 and 62 protruding from the lower side of the plate 61 and a pair of engaging projections 63 and 63 protruding near the upper edge of the front plate 60 are provided. .

The front plate 60 of the outer cover 6 has a crank shape corresponding to the side shape of the hole 25 which connects and pulls out the upper half 60a and the lower half 60b approximately horizontal to the rear position thereof by the connecting plate. It has a side cross-sectional shape and has a predetermined bending strength secured by reinforcing ribs protruding along the circumferential edge of the upper half portion 60a. The compression plates 61 and 61 are installed at an appropriate height on the upper surface of the connecting plate, and tapered edges 61a and 61a inclined downward from the rear thereof are formed on the rear portion thereof. The inclinations of these tapered edges 61a and 61a are set substantially equal to the inclinations of the tapered edges 51a and 51a formed in the side plate 51 of the shutter 5.

The upper wedge portions 62, 62 protruding on both sides of the compression plates 61, 61 have a rear surface having a continuous slope to the tapered edges 61a, 61a and a front surface having less slope than this. It is a wedge shaped to reduce the width toward the tip. The inclination of the front surface is set substantially equal to the inclination of the taper part of the guide rib 24. In addition, the engaging projections 63 and 63 protruding from the top of the front plate are provided with hooks 63a and 63a integrally formed at the lower edges, respectively, and these protruding installation positions are provided in the shutter 5. Corresponding to the positions of the formed engaging holes 54 and 54.

The outer cover 6 configured as described above has the shutter 5 mounted on the inner side of the outer cover 6 by the upper wedge portions 62 and 62 when the outer cover 6 is mounted in a state of closing the ejection hole 25. While retaining the correct mounting condition, the hooks 63a and 63a of the lower edges of the engaging projections 63 and 63 are engaged with the engaging holes 54 and 54 provided in the shutter 5. As a result, the exterior cover 6 can be kept in a correct mounting state as will be described later. 8 and 9 are enlarged cross-sectional views near the mounting position of the shutter 5 and the exterior cover 6 for explaining the operation of the upper wedge 62 and the engaging projection 63. FIG. 8 is a shutter 5 and the exterior. 9 shows the state before the exterior cover 6 is mounted.

As shown in FIG. 8, the exterior cover 6 precedes the tapered edge 61a of the compression plate 61 continuous to the rear and upper portions of the upper wedge portion 62 protruding from the rear side of the front plate 60. The taper edge 51a on the front surface of the side wall 51 of the attached shutter 5 is mounted in contact with the taper edge 51a.

In this mounting state, as shown in Fig. 9, the wedge-shaped upper end portion 62 has a thin tip between the tapered portions of the guide ribs 24 facing each other by the mounting of the shutter 5 and the tapered edges 51a opposite to each other. And the tapered edge 61a and the wedge upper portion 62 of the outer cover 6 contacting the tapered edge 51a in the shutter 5 in this state with a white arrow in FIG. 8. As shown, it is compressed to the rear side and restrained in the state which the outlet 17 formed in the process tank 1 was obstructed.

The state of restraint of the shutter 5 thus obtained is firmly maintained by the frictional force on the front and rear surfaces of the upper wedge portion 62, and the shutter 5 is the weight of the carrier A inside the processing tank 1 and stirred. It is possible to maintain a normal occlusion state without moving by the action force accompanying the stirring of the support A by the sieve 4.

(64) is protrudingly bonded.

As shown in Fig. 12, the mounting detection switch 7 is pressed by the compression rod 64 that enters the through hole 19 through the through hole 55 when the shutter 5 and the outer cover 6 are mounted. It is set to ON.

When the exterior cover 6 is mounted without the shutter 5 mounted, as described above, the inclined conduction is formed in a state in which a gap is formed between the upper edge of the front plate 60 and the front surface of the exterior cover 2. As a result, the compression rod 64 is inclined upward with its tip as indicated by the dotted line in Fig. 12 so that the mounting detection switch 7 is turned off. As shown in Fig. 11, it goes without saying that the mounting detection switch 7 is turned OFF when only the shutter 5 is mounted and the shutter 5 and the external cover 6 are not mounted.

That is, the mounting detection switch 7 is turned ON only when the shutter 5 and the exterior cover 6 are correctly mounted together, and the compression rod 64 is kept substantially horizontal as shown by the solid line in FIG. 12. By turning on / off the detection switch 7, it is possible to reliably detect whether the shutter 5 and the exterior cover 6 are mounted.

Both parts of the mounting state of the shutter 5 and the exterior cover 6 detected in this way may be notified to the user by, for example, a notification means such as lighting of a display lamp or an alarm. In this case, the driving is prohibited. The prohibition of this operation is performed by the heater H performed as described above when the mounting detection switch 7 is connected to the input side of the operation control unit configured on the control board 3 and the mounting detection switch 7 is in the OFF state. This can be achieved by a configuration in which control is performed to prevent the energization, the driving of the ventilation fan, and the driving of the stirring motor M. Thereby, there is no possibility that driving is performed in a state where mounting of the shutter 5 and / or the outer cover 6 is impossible.

13 to 15 show a second embodiment of the present invention. In the first embodiment, the mounting detection switch 7 is turned ON by holding the exterior cover 6 in the attached state regardless of whether the shutter 5 is attached or not. In this case, both the shutter 5 and the exterior cover 6 are attached, and the mounting detection switch 7 is turned ON for the first time.

13 is a state in which the shutter 5 and the outer cover 6 are not mounted, FIG. 14 is a state in which the shutter 5 and the outer cover 6 are mounted, and FIG. 15 is a state in which only the shutter 5 is mounted. Indicates.

In the mounting state of the shutter 5 shown in FIG. 15 on the lower surface of the processing tank 1, the outer case 2 of the outer case 2 is positioned at a position facing the front plate 52 of the shutter 5 protrudingly provided. The cover plate 18 which extends to the bottom face is hanged, and the mounting detection switch 7 is arrange | positioned on the back side of the cover plate 18 toward the through-hole 19 of small diameter which penetrates the cover plate 18. As shown in FIG.

In addition, in the front plate 52 of the shutter 5, a compression cylinder 65 having a bottom shape made of a material rich in elasticity such as rubber and the like is placed at the bottom side of the front plate 52 in a fitted state. Is attached toward the through hole 19. Again, the compression protrusion 62 protrudes from the front plate 60 of the exterior cover 6 at a position that matches the through hole 19 and the compression cylinder 65 in the mounting state.

The mounting detecting means is constituted by the mounting detecting switch 7, the compression cylinder 65, and the compression protrusion 62 as described above, and the mounting detecting switch 7 has a shutter 5 and an outer cover (as shown in FIG. 6) If it is not attached, it is in an OFF state, and as shown in Fig. 14, when the shutter 5 and the outer cover 6 are mounted, the mounting detection switch is mounted by the compression protrusion 62 via the compression cylinder 65. (7) is pressed to be ON.

FIG. 15 shows a state in which only the shutter 5 is mounted, wherein the bottom surface of the compression cylinder 65 of the shutter 5 abuts the mounting detection switch 7, but the compression cylinder 65 is elastic as described above. The bottom surface of the compression cylinder 65 is deformed by being deformed by the mounting detection switch 7 and deformed, and the mounting detection switch 7 is kept in the OFF state. Also, even when the shutter 5 is not mounted, the compression protrusion 62 has a length that does not reach the mounting detection switch 7, and the mounting detection switch 7 is in an OFF state even when only the exterior cover 6 is mounted. It is supposed to keep.

That is, as shown in Fig. 14, the mounting detection switch 7 is turned ON, and the compression cylinder 65 is mounted between the compression protrusion 62 and the mounting detection switch 7 as the shutter 5 and the exterior cover 6 are mounted. Only when the tip of the compression protrusion 62 is compressed by the mounting detection switch 7 via the bottom plate of the compression cylinder 65, and the shutter 5 and It is possible to reliably detect whether the exterior cover 6 is in a mounted state.

The mounting state of the shutter 5 and the exterior cover 6 detected in this way is given to an operation control unit configured on the control board 3. The operation control unit recognizes whether the mounting state is detected by the ON / OFF of the mounting detection switch 7, and notifies the user by, for example, a notification means such as the occurrence of a warning of lighting of the display lamp when the mounting state is in an unstable state. Perform the operation. Thereby, there is no possibility that the carrier A will be introduced while the shutter 5 and the exterior cover 6 are in an unsuitable state. Again, the operation control unit prohibits the operation operation including the drive of the stirring motor (M) when in the state of mounting failure.

In this case, the operation is not performed without leaving the shutter 5 and the exterior cover 6 unmounted, and the occurrence of irrationality can be prevented. Such a configuration allows the output of the operation command to the stirring motor M on the output side when it is determined that the mounting switch 7 is in the OFF state and at least one of the shutters 5 or the exterior cover 6 is in the state of mounting failure. This is easily achieved by inhibiting the output of the operation command to the ventilation fan and the heater H at this time.

According to the configuration of claim 1 of the present invention, by attaching the outer cover to the shutter with the shutter attached, the outer cover can be used to constrain the shutter to the closed state of the discharge port and at the same time to confine the outer cover to the closed position of the hole for removing the outer cover. It is possible to drastically reduce the trouble of attaching and detaching the outer case and shutter for changing the carrier, and the generation of odor due to the leakage of the carrier from the inside of the processing tank, and the deterioration of organic matter treatment efficiency due to the failure of attaching the outer case. It is possible to prevent such effects.

According to the configuration of claim 2 of the present invention, when the external cover is mounted without noticing the unmounted state of the shutter, the user cannot visually attach the shutter because the external cover cannot be fitted to the shutter and the external cover cannot be mounted. This can be confirmed by the present invention, and it is possible to prevent the occurrence of odor due to leakage of the carrier from the inside of the treatment tank.

According to the configuration of claim 3 of the present invention, when the external cover is mounted without noticing the unmounted state of the shutter, the external cover cannot be fitted to the shutter and the external cover cannot be kept in the mounted state, so the switch is operated by the external cover. It is not possible to make it possible to inform the user that the shutter is not mounted and to prevent the occurrence of odor due to leakage of carrier from the inside of the treatment tank.

According to the configuration of claim 4 of the present invention, the operation of the organic matter treatment apparatus is prevented when the shutter or the exterior cover is in an inadequate state, thereby preventing the occurrence of odor due to leakage of the carrier from the inside of the processing tank due to the improper attachment of the shutter. At the same time, it is possible to prevent the degradation of organic matter treatment efficiency due to the failure of mounting the outer case.

According to the configuration of claim 5 of the present invention, the mounting failure of at least one of the shutter and the exterior cover can be detected, thereby preventing the occurrence of odor due to leakage of the carrier from the inside of the processing tank due to the mounting failure of the shutter. It is possible to prevent the degradation of organic matter treatment efficiency due to the inability to attach the outer case.

According to the configuration of claim 6 of the present invention, the mounting failure of at least one of the shutter or the exterior cover can be reliably detected, and thus, the simple configuration prevents the occurrence of odor due to leakage of the carrier from the inside of the processing tank due to the mounting failure of the shutter. At the same time, it is possible to prevent the degradation of organic matter treatment efficiency due to the failure of mounting the outer case.

According to the structure of claim 7, the operation of the organic matter treating apparatus can be controlled when at least one of the shutter and the outer cover is not mounted, and the odor due to leakage of the carrier from the inside of the processing tank due to the mounting failure of the shutter can be controlled. It is possible to prevent the occurrence and at the same time to prevent the degradation of the organic matter treatment efficiency due to the mounting failure of the outer case.
