Description

Apparatus for treating organic materials

The present invention relates to an organic material processing apparatus for treating organic matter such as food waste, and more particularly, to an improvement in a filter mechanism for preventing fine powder such as food waste scattered in a treatment tank from flowing out of an exhaust port.

As an organic material processing apparatus for treating organic matters such as food waste, a carrier of microorganisms that decomposes organic matters is stored in a treatment tank, and the organic matter is fermented while maintaining the inside of the processing tank at an activation temperature of the microorganism (for example, about 60 ° C). The microorganisms may be decomposed or decomposed by heating and drying the organic matter in the treatment bath at a higher temperature without using microorganisms.

In any of these cases, water contained in organic matters such as food waste is evaporated to be discharged to the outside as an exhaust gas containing water vapor. However, the exhaust gas contains odor generated during decomposition of organic matter.

Like the odor generated during decomposition of organic matter such as food waste as described above, the component or amount of the odor is not constant, and as a deodorization method at a high concentration, the exhaust gas containing the odor is heated to about 300 ° C. or more. , A method of contacting with a catalyst to oxidize and decompose is effective.

Conventionally, by using the exhaust gas heated by the above deodorization mechanism effectively, while heating a processing tank bottom part, the outside air supplied to a processing tank is heated, the whole food tank is kept at the activation temperature of microorganisms, Background Art An apparatus for decomposing organic matter such as waste is known.

In this organic matter treatment apparatus, the exhaust gas discharged through the filter 1b in the treatment tank 1 is supplied to the deodorization mechanism 4, heated by the heater 2 to about 300 ° C. or more, and the heated exhaust gas passes through the catalyst 3. Deodorized. The high temperature exhaust gas passing through the deodorization mechanism 4 and around 250 ° C. enters the inner cylinder 5a side of the double-cylinder heat exchanger 5, preheats the outside air by heat exchange with the outside air through the outer cylinder 5b side, and warms it to around 60 ° C. It is fed into the treatment tank 1. On the other hand, the high temperature exhaust gas passing through the inner cylinder 5a side of the heat exchanger 5 is supplied to the double bottom 1a of the treatment tank 1 while maintaining the temperature of 150 ° C to 200 ° C, and after the treatment tank 1 is heated, To be discharged to

By the way, in such a conventional apparatus, since the filter 1b is comprised so that it may cover the exhaust opening opened in the processing tank 1, in order to remove the fine powder, such as food waste attached to the filter 1b, by washing | cleaning etc., It was difficult to remove the filter 1b by putting a hand in the tank 1 to remove the filter 1b.

In addition, relatively large dust and garbage are easily attached to the filter surface of the treatment tank 1 side to the filter 1b used in these kinds of apparatuses, but these must be removed by removing the filter 1b, Garbage can be sent back into treatment tank 1, but this is a time-consuming task.

Accordingly, the present invention has been made to solve such a problem, and an object of the present invention is to provide an organic matter treatment apparatus that can easily detach a filter without putting a hand into a treatment tank.

It is also an object of the present invention to automatically remove a relatively large dust or trash attached to a filter and return it to a treatment tank.

Moreover, the frame of the said filter was formed in the ship shape, It is characterized by the above-mentioned.

Embodiment of this invention is described in detail with reference to FIGS.

This organic material processing apparatus is used for a business, for example in a convenience store etc., The processing tank 11 in which the bottom part was formed in the double bottom structure in the substantially U-shaped side cross section is accommodated inside the main body case 10. As shown in FIG. 6, this treatment tank 11 has a large capacity for decomposing and treating food waste, in which microbial carriers (usually wood chips such as sawdust) are stored, and this article 11a. Partitions are partitioned by partition plate 12 in Article 211b, which has a small capacity to be transported in order to discharge the treated material.

In one upper part of the partition plate 12, a conveyance port 12a for conveying the processed material in Article 1 1 a to Article 2 12b is formed, and the conveyance port 12a is freely opened and closed by a hinge or the like. Transfer door 12b is installed. The transfer door 12b is provided on the side of the second set 11b of the partition plate 12, and is formed larger than the transfer opening 12a as shown in FIG. 17 and the like, and is only shown in FIG. 20 when transferring from the first set 11a to the second set 11b. As shown, the processed material D is opened and the processed material D is not returned to Article 1 1 a.

Moreover, the discharge port 13a which is located in the lower side opposite to the said conveyance port 12a on the side wall of 2nd tank 11b and discharges a process material is formed. 10 to 12, the shutter 13c is freely mounted on the sliding frame 13b formed on both sides of the discharge port 13a, and can be opened and closed by operating the lever 13d.

Magnets MG1 and MG2 for reed switch ON / OFF are mounted above and below the side surface of 13c. Correspondingly, in the sliding frame 13b, the reed switch SW1 which is turned on to face the magnet MG1 at the upper side when the shutter is closed is closed, and the reed switch SW2 which is turned on to face the lower magnet MG2 when the shutter is opened at 13c. Is provided, and opening and closing of the shutter 13c can be detected by detecting them with a control unit (not shown).

On the other hand, the upper surface of the main body case 10 has a step structure in which all of the lower back is high and the rear is high, and all of the lower backs correspond to the upper opening of the treatment tank 11 to open the microorganism carrier or food waste. An inlet port 14 for injecting is formed, and the inlet port 14 is provided with an upper lid 15 (lid body) freely opened and closed by a hinge or the like. As shown in Fig. 8, a magnet MG3 for detecting the upper lid opening / closing is mounted at a predetermined position of the circumference of the upper lid 15, and the lid constituting the lid detecting portion together with the magnet MG3 on the upper part of the main body case 10 corresponding thereto. The switch SW3 is attached, and the opening / closing state of the upper lid 15 can be detected by detecting the ON / OFF of the reed switch SW3 by the controller. Moreover, the leg part 10a is attached to four ears of the lower surface side of the main body case 10.

An inlet 16 for intake of outside air into the treatment tank 11 is formed at an upper portion of the treatment tank 11 (right side in FIG. 1), and an exhaust port 17 for discharging the exhaust gas out of the treatment tank 11 in the upper center portion. Is formed, and the exhaust port 17 is equipped with a filter 18 which prevents fine particles such as carriers and food wastes scattered in the treatment tank 11 from flowing out of the exhaust port 17.

As shown in FIG. 2, FIG. 8 etc., the said filter 18 is comprised so that it may be inserted in inclined direction from the outer side to the base end 17a of the exhaust flow path of the exhaust port 17, and as shown in FIG. 2 at the time of closing of the said upper lid 15, The handle 18a of the filter 18 touches the side wall of the closed upper lid 15 so that it cannot be lifted out.

Moreover, as shown in FIG. 9, this filter 18 attaches a mesh net 18c to the bottom face side of the ship-shaped frame 18b, and uses a nonwoven fabric etc. on it, and makes frame 18b a ship shape, By providing the guide 18f, it is easy to insert into the insertion opening 18d formed in the stepped corner part of the upper surface of the main body case 10.

In addition, since the filter area is inserted into the base end portion 17a of the exhaust flow path at the exhaust port 17 in an oblique direction, the filter area can be largely enlarged with respect to the exhaust flow path, so that the filter efficiency can be improved and the ventilation resistance can be reduced. have.

Moreover, it is not necessary to put a hand in the processing tank 11 and remove the filter 18 like conventionally, and handling is extremely simple.

In addition, the upper front wall of the exhaust port 17 is provided with a scraper (sliding contact member) 18e which is in sliding contact with the mesh 18c on the mesh of the bottom surface of the filter 18, so that the mesh on the bottom side of the filter 18 when the filter 18 is lifted out. It is possible to automatically scrape and drop relatively large dust or trash attached to the upper mesh 18c into the treatment tank 11 without touching it.

As shown in Fig. 13, a magnet MG4 for reed switch ON / OFF is attached to a part of the handle 18a of the filter 18, and a filter detection portion is formed together with the magnet MG4 at a portion corresponding to the upper lid 15. Reed switch SW4 is installed. Thus, under the closed state of the upper lid 15, the unattached filter 18 can be detected by the control unit, and the start of operation of the unfiltered human body of the filter 18 can be prevented in advance. As described above, the filter 18 cannot be lifted mechanically unless the upper lid 15 is opened. When the upper lid 15 is opened, the operation of the device is stopped and the blowing is stopped. Since the fine powder in the processing tank 11 flows into the deodorization mechanism mentioned later, it is possible to prevent the bad state, such as the possibility of burning by the heater and clogging of the hole of the catalyst.

A corrugated flexible duct 19 made of a heat transfer pipe such as stainless steel is connected to the base end portion 17a of the exhaust port 17, and the duct 19 is connected to the deodorizing mechanism 40 through the double bottom 11d of the treatment tank 11.

The deodorizing mechanism 40 has a configuration in which a heater 20 is disposed on an exhaust gas inlet side, and a catalyst 30 is disposed downstream of the heater 20, so that the exhaust gas flowing in is heated by the heater 20, and the heated exhaust gas is heated. The catalyst 30 is also heated by passing through the catalyst 30, so that the decomposition reaction of the odor component contained in the exhaust gas is promoted.

In the present embodiment, as shown in FIG. 4, the heater 20 is provided with a plurality of vent holes 22 in a rectangular parallelepiped 21 made of quartz or ceramic, and passes through nichrome wire 23 therein, and deodorizes through a heat insulating material 24. It is housed in the case 41 of the mechanism 40. In addition, the catalyst 30 is a cylindrical shape in which the honeycomb fine air vent 31 was formed, and is accommodated in the case 41 through the heat insulating material 32. As shown in FIG.

The outlet side of the deodorization mechanism 40 is connected to one of the double bottoms 11d of the treatment tank 11 via the flexible duct 42, and the high temperature exhaust gas of the deodorization mechanism 40 passes through the double bottom 11d of the treatment tank 11 in the treatment tank 11. It is comprised so that it may directly contact the said flexible duct 19 which let the waste gas pass. Thus, the other discharge port of the double bottom portion 11d is connected to the blower 60 disposed on the rear upper part of the main body case 10 via the flexible duct 43, so that the exhaust gas is discharged to the outside.

On the other hand, a corrugated flexible duct 44 made of a heat transfer pipe such as stainless steel is connected to the inlet 16 of the treatment tank 11, and the duct 44 sucks outside air through the double bottom 11d of the treatment tank 11.

By the configuration as described above, the outside air supplied into the processing tank 11 through the flexible duct 44 passing through the double bottom 11d of the treatment tank 11 and the deodorizing mechanism 40 and the hot exhaust gas supplied to the double bottom 11d of the treatment tank 11 are heat-exchanged. Since the outside air supplied to the processing tank 11 is heated to around 60 ° C. (primary preheating), a conventional double-cylinder heat exchanger becomes unnecessary, so that the number of parts can be reduced and the cost can be reduced. In addition, since the space for arranging the independent heat exchanger as in the prior art is unnecessary, the apparatus can be miniaturized. Again, the high temperature exhaust gas directly enters the double bottom 11d of the treatment tank 11 without passing through the heat exchanger in the deodorizing mechanism 40, so that the thermal efficiency is good.

On the other hand, the exhaust gas (around 60 ° C) from the treatment tank 11 supplied to the deodorization mechanism 40 via the flexible duct 19 through the double bottom 11d of the treatment tank 11 and the high temperature supplied to the double bottom 11d of the treatment tank 11 from the deodorization mechanism 40 Since the exhaust gas (about 250 ° C.) heat exchanges, and the exhaust gas supplied to the deodorization mechanism 40 is heated to about 150 ° C. (secondary preheating), the conduction rate of the heater 20 in the deodorization mechanism 40 is lowered, thereby reducing the electric charge. The driving cost can be reduced. The high temperature exhaust gas supplied from the deodorization mechanism 40 to the double bottom 11d of the treatment tank 11 is comprised directly in the said flexible duct 19 through the double bottom 11d of the treatment tank 11, and the temperature of the exhaust gas supplied to the deodorization mechanism 40 is carried out. Making it easier to climb.

Moreover, since the temperature of the high temperature exhaust gas (about 250 degreeC) supplied to the double bottom part 11d of the processing tank 11 by the deodorization mechanism 40 falls by the heat exchange mentioned above, excessive heating of the processing tank 11 is suppressed.

These have been made possible by effectively utilizing the arrangement which was conventionally discharged in vain.

On the other hand, as shown in FIG. 5, FIG. 6, etc., in the said processing tank 11, between a both side wall, a plurality of stirring blades 70a-70e (here, four in Article 11a, one in Article 11b) The stirring shaft 71 provided is installed so that forward and reverse rotation is possible. Both ends of the stirring shaft 71 are supported by the bearing 72 of the side wall of the treatment tank 11, and the replacement wheel 73 mounted on one shaft end is connected to the small gear 76 of the stirring motor 75 via the chain 74. The rotation of the agitation motor is decelerated and transmitted, and the motor is rotated.

For example, the stirring motor 75 rotates intermittently for about 2 minutes each time food waste is put into the treatment tank 11 and the upper lid 15 is closed or once every 4 minutes in the normal operation mode. (Forward rotation). In addition, at the time of conveyance of Article 11a from Article 11a to Article 11b, as shown in Figs. 18 and 19, the stirring object 70a to 70d is rotated and driven in the direction in which the workpiece D is scraped up toward the feed port 12a ( Reverse rotation), at the time of discharging the processed material and during the normal operation, as shown in Figs. 15 and 16, in the second article 11b, the processed material D is scraped up toward the discharge port 13a with the stirring blade 70e. In 1 tank 11a, it rotates by the stirring blades 70a-70d in the direction away from the feeder 12a (forward rotation).

Generally, this kind of stirring blade is provided on the stirring shaft at equal intervals, but in this embodiment, in order to improve the conveyance efficiency at the time of conveying the processed object in Article 11a to Article 211b, the conveyance port The gap is gradually narrowed toward 12a (in Fig. 15, A &gt; B &gt; C).

Moreover, each stirring blade 70a-70d of Article 1 11a is provided in the spirally mounted on the stirring shaft 71. As shown in FIG.

The twisting direction is the workpiece D during normal operation and during forward rotation during discharge. The workpiece D moves to the opposite side (inner side) of the transfer port 12a, and at the reverse of transfer from Article 1 1a to Article 2 1 b. In the same direction as moving toward the feed port 12a.

By the way, following the above structure, a certain amount of microbial carriers is pre-injected into Article 11a of the treatment tank 11 at the start of use of the apparatus. Thus, when disposing of food waste, the top lid 15 is opened to feed the food waste into the first article 11a of the treatment tank 11 from the inlet 14, the operation switch (not shown) is turned ON, and the top lid 15 is closed. When the upper lid 15 is closed, this is detected by the reed switch SW3, the output thereof, the ON output of the reed switch SW1 indicating that the shutter of the exhaust port 13a is closed, and the lid indicating that the filter 18 is attached to the exhaust port 17. Based on the ON output of the switch SW4, the control unit energizes the deodorizing mechanism heater 20, the exhaust blower 60, and the stirring motor 75.

By energizing the stirring motor 75, the stirring shaft 71 on which the plurality of stirring blades 70a to 70e are mounted is intermittently rotated, and the carrier and the food waste put into the first article 11a are stirred and mixed. At the time of this forward rotation, since the stirring blades 70a to 70d rotate in the direction (clockwise) indicated by the arrow in Fig. 16, the treated material D in Article 11a in which the carrier and the food waste are stir-mixed is the same as the above. As shown in FIG. 15, since it is in the direction away from the conveyance port 12a, the unprocessed processed material D is not conveyed to Article 211b.

Moreover, the flexible duct 19 and the deodorization mechanism 40 which let the air (exhaust gas) containing the water vapor and odor in the processing tank 11 pass through the exhaust port 17, the filter 18, and the double bottom 11d of the processing tank 11 by the electricity supply to the exhaust fan 60 for exhaust. To the outside through the double bottom 11d of the treatment tank 11 and the blower 60, to prevent the treatment tank 11 from becoming in a high humidity state and to discharge the air in the treatment tank 11 to the outside. Fresh air is drawn in from the inlet 16 through the flexible duct 44 through the double bottom 11d of the treatment tank 11 to supply oxygen necessary for the activation of microorganisms in the treatment tank 11.

Again, by the energization control of the deodorizing mechanism 40 to the heater 20, the exhaust gas discharged from the exhaust port 17 as described above is heated to a catalytic reaction temperature of 300 deg. The hot exhaust gas supplied into the catalyst 30 is heated to the same temperature, deodorized by the oxidative decomposition reaction of the malodor promoted by the catalytic action, and is almost completely odorless between the catalysts 30. It becomes mad. The odorless high-temperature exhaust gas is introduced into the treatment tank double bottom 11d at a temperature of about 250 ° C, and exhaust gas is supplied to the flexible duct 44 and the deodorization mechanism 40 through which outside air is supplied to the treatment tank 11 and the treatment tank 11. The flexible duct 19 to let it pass is heated, and is discharged | emitted outside through the blower 60 provided in the upper upper part of the main body case 10 after that.

As described above, the flexible duct 44 through which the outside air to be supplied to the treatment tank 11 passes through the double bottom 11d furnace of the treatment tank 11, so that the hot exhaust gas from the deodorizing mechanism 40 heated by the energization control of the heater 20 is The outside air is heat-exchanged (primary preheating), and the outside air warmed to about 60 ° C is supplied into the treatment tank 11. Moreover, since the flexible duct 19 which passed the exhaust gas supplied to the deodorizing mechanism 40 also passes through the double bottom 11d of the processing tank 11, the high temperature exhaust gas and the processing tank 11 in the deodorizing mechanism 40 heated by the electricity supply control to the said heater 20 are also provided. Exhaust gas from the heat exchanger (secondary preheating) is supplied into the deodorization mechanism 40 by the exhaust gas warmed around 150 ° C.

In this way, the air entering the heater 20 of the deodorizing mechanism 40 is preheated in two stages, so that the temperature rise by the heater 20 can be suppressed by about 300 ° C. to about 150 ° C. = about 150 ° C. by design. 60 ° C = about 90 ° C less than about 240 ° C, so that the current carrying ratio of the heater 20 can be lowered, the electric charge can be lowered, and the operating cost can be lowered.

By controlling as described above, the whole temperature in the treatment tank 11 is maintained in the optimum range (about 60 ° C) for the activation of microorganisms and fermented, and the food waste is composted by decomposing food waste into carbon dioxide and water by microorganisms cultured on a carrier. do.

When the above process is performed, for example, for 18 hours or more, and the composting of the processed material D is almost finished, the control unit drives the stirring motor 75 in reverse rotation. At the time of reverse rotation, since the stirring blades 70a to 70d in the first tank 11a rotate in the direction (counterclockwise direction) indicated by the arrow in FIG. 19, the treated material D composted in the first tank 11a is As shown in Fig. 18 or Fig. 18, the scraping is carried out toward the feed port 12a, and as shown in Fig. 20, the processed material D is pushed open to the transfer door 12b and transferred to Article 2b.

In this embodiment, since the space | interval of stirring blades 70a-70d is gradually narrowed toward the feed port 12a, the processed material D in Article 11a can be efficiently transferred to Article 211b in a short time.

When removing the processed material D composted as mentioned above and conveyed to Article 211b, the shutter of the discharge port 13a is opened as shown in FIG. 12 by operating 13c with the lever 13d. When the shutter is opened as shown in FIG. 12, the reed switch SW2 is turned on. Therefore, the control unit detects this and drives the stirring motor 75 for forward rotation. At the time of this forward rotation, the stirring blades 70a to 70e rotate as shown in Fig. 16 as in the normal operation, so that the treated material D transferred to Article 2b is scraped up toward the outlet 13a, and efficiently at the outlet 13a. Pulled out. Treatment D removed is effectively used as an organic fertilizer. Furthermore, since the processed material D in Article 1 1 a at the time of discharging is in a direction away from the feed port 12a as shown in FIG. 15 as in the normal operation described above, the unprocessed processed material D is transferred to Article 2 1 1B. There is no work.

If the above process is repeated, the holes of the filter 18 are clogged, and the efficiency of exhaust and intake is reduced, so that maintenance such as cleaning of the filter 18 is required. In particular, in this kind of organic matter treatment apparatus, when the treatment tank 11 dries with the progress of the treatment, a large amount of fines of food waste and carrier are scattered, and clogging of the filter 18 is easy, so that the filter 18 is cleaned. Since the maintenance of the filter and the like must be made frequently, the handling of the filter 18 is extremely simple since the detachment and detachment of the filter 18 can be facilitated from the outside without putting a hand in the treatment tank 11.

In addition, as described above, the filter 18 can be lifted from the outside, so that the filter 18 accidentally escapes during operation of the apparatus, and the fine powder in the treatment tank 11 flows into the deodorizing mechanism 40 and burns by the heater 20. Although it is thought that bad phenomena such as clogging of the catalyst 30 will occur, in the present embodiment, the upper lid 15 is configured such that the filter 18 cannot be lifted out in the closed state, thereby preventing such inconveniences. Can be.

In addition, when removing the filter 18, a relatively large dust and rubbish adhering to the mesh 18c on the mesh surface on the bottom side of the filter 18 are automatically scraped off by the scraper 18e and dropped into the treatment tank 11, so that it takes not the same time as the conventional one. Will not.

Again, after the maintenance of the filter 18, the operation of the device is forgotten even if the operation of the device is forgotten even if the filter 18 is forgotten. Therefore, as described above, fine powder in the treatment tank 11 flows into the deodorization mechanism 40 due to the non-installation of the filter 18, and the heater It is possible to prevent the occurrence of a bad phenomenon such as the possibility of burning by 20 or clogging of the pores of the catalyst 30.

Moreover, also in this embodiment, the hot exhaust gas supplied to the double bottom part 11d of the processing tank 11 through the flexible duct 42 by the deodorization mechanism 40 forms the passage 19a which passes the exhaust gas in the processing tank 11. If it is comprised so that it may directly contact the thermal partition wall 11e, the temperature of the exhaust gas supplied to the deodorization mechanism 40 can be made easier to rise.

Moreover, in the said embodiment, both the outside air supplied in the processing tank 11, and the exhaust gas supplied to the deodorization mechanism 40 from the processing tank 11 are made to pass through the duct in the double bottom 11a of the processing tank 11, or to a heat-resistant partition wall. Although the air flow path is formed, either one may be made to pass through a duct and the other may be made to form an air flow path by an electrothermal partition.

In addition, in each said embodiment, although the transfer door 12b of the transfer tool 12a was shown with the upper part mounted by the hinge etc., as shown in FIG. 22, the lower part was attached by the hinge etc., and the transfer port 12a by a spring etc. It may be configured so that a force is applied in the direction of closing the.

In the above embodiments, the present invention has been described in application to a large-scale organic matter processing apparatus mainly used for business purposes, but it is also applicable to a small-volume household use, and it is possible to apply food by heating and drying without using microorganisms. It is also applicable to the treatment of organic matter such as garbage.

As described above, according to the present invention, a treatment tank for processing organic matters such as food waste to be introduced, a main body case accommodating the treatment tank, a blower for discharging the exhaust gas of the treatment tank to the outside, and an exhaust gas of the treatment tank. Since the discharge passage is provided with a filter detachably mounted on the outside of the main body case, the detachment of the filter can be easily carried out without putting a hand in the treatment tank, and the handling becomes simple.

The above is more effective when the organic matter such as food waste is decomposed by using microorganisms that reproduce on the carrier, but the same can be applied to the treatment of organic matter such as food waste by heat drying without using microorganisms. The effect can be obtained.

Furthermore, by providing a sliding contact member in sliding contact with the surface of the filter tank side of the filter and scraping off the deposit on the filter surface and dropping it into the processing tank when the filter is lifted out, the relatively large dust and garbage attached to the filter are automatically removed. It can remove and return to a processing tank, and it will not take time as usual.

The lid detecting unit detects the opening / closing state of the lid for opening and closing the inlet of the treatment tank, and the control unit controls the operation including the blower to a stop state when the lid opening state is detected in the lid detecting unit, and the lid is closed. In this state, the lid is an obstacle and the filter cannot be lifted. As a result, the filter can be lifted from the outside as described above, so that the bad state caused by the filter being pulled out during operation of the device can be prevented in advance. .

In addition, in the closed state of the lid, a filter detecting unit is provided for detecting a non-attachment state of the filter, and the control unit controls the operation including the blower to a stop state when the undetected state of the filter is detected in the filter detecting unit. It is possible to prevent the start of operation in the unmounted state.

Further, the electric filter is configured to be mounted in an inclined direction with respect to the exhaust flow path of the exhaust gas of the treatment tank, so that the filter area with respect to the exhaust flow path can be made large, so that the filter efficiency can be improved and the ventilation resistance can be reduced.

Moreover, the frame of the above-mentioned filter is formed in double shape, and it is easy to attach a filter from the outer side of a main body case.
