Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a straw processing apparatus that treats garbage (slag) generated in a kitchen using a decomposition action by microorganisms.
[0002]
[Prior art]
If left unattended in kitchens of ordinary households, restaurants, etc., if left unattended, it will cause the generation of bad odor due to corruption and the propagation of pests, which will worsen the sanitary environment of the kitchen. Need to be processed.
[0003]
Conventional dredging treatment is generally performed by installing a draining basket at the drain outlet of the sink, capturing the dredging thrown into the draining basket with drainage, taking it out appropriately, and discarding it with other garbage. ing. In Europe and the United States, a waste crusher (disposer) is connected to the drain outlet of the sink, and the waste thrown into the drain outlet by the operation of the disposer is finely crushed, and the drain pipe connected to the drain outlet together with the drainage. The soot disposal method of disposing of wastewater through sewage is widely adopted.
[0004]
[Problems to be solved by the invention]
However, in the former method, when removing the trap caught in the draining basket, bad smell generated from the spoiled trap fills the kitchen, and inconveniences such as spillage spill out into the sink of the sink occur. In order to maintain a good sanitary environment, it is necessary to frequently take out and dispose of the basket, and there is a problem that a great labor load is imposed such as washing the draining basket each time this is taken out.
[0005]
On the other hand, the latter method is effective in maintaining a sanitary environment because the soot is treated without stagnation, but the crushed soot is discarded together with the waste water, so that the sewer pipe is blocked and the sewage treatment plant is disposed. This causes secondary inconveniences such as an increase in load. In particular, in Japan, where there are many sewers combined with rainwater, the overflow of natural waters such as rivers and lakes due to the overflow of overflow water from sewage may cause eutrophication. , The allowable values of suspended solids (SS) and biological scientific oxygen demand (BOD) in wastewater to public sewers are strictly regulated, and wastewater from disposers that contain crushed soot and present a dense liquid The fact is that the above-mentioned regulations cannot be satisfied and the disposition process by the disposer is prohibited.
[0006]
Japanese Patent Laid-Open No. 4-156959 also discloses that the dredging thrown into the drain outlet of the sink is drained while being conveyed by a screw, collected in a dredging bag attached to the discharge port at the end of the conveying path, and a predetermined collection There has been disclosed a scissor treatment device configured to automatically seal the bag mouth when the amount is reached. However, even when this bag processing apparatus is used, it is troublesome to take out and attach the bag, and there is a possibility that the bag may remain in the middle of the transfer route and become corrupted. There is a difficulty in cleaning.
[0007]
The applicant of the present application has already proposed a wrinkle processing apparatus that can solve the above-described drawbacks of wrinkle processing. This means that the straw put into the drain outlet of the sink is crushed by the crushing means connected to the drain outlet, introduced into the treatment tank, and mixed with the treatment medium stored in the treatment tank. It is a device with a simple configuration. The treatment medium is a microbial culture substrate such as wood strips, rice husks, rice bran, and soil, and an environment suitable for propagation of various microorganisms (fungi) is present inside the treatment tank containing the treatment medium. Is formed. Thus, the debris introduced into the treatment tank and mixed with the treatment medium is converted into water (H2 O) and carbon dioxide (CO2) by the microorganisms introduced together with them and propagated in the treatment medium. Disassembled.
[0008]
In other words, when this dredging device is used, the user is only required to perform a simple operation of sending dredging to the crushing means connected to the drain outlet, and the water generated as a result of the decomposition is discarded into the drain pipe. However, the soot can be completely extinguished by releasing carbon dioxide gas to the periphery of the treatment tank, and a sanitary soot treatment can be realized with a small labor burden.
[0009]
In the soot treatment apparatus as described above, soot introduced into the treatment tank is slowly decayed by the activity of microorganisms in an anaerobic environment, and then water is produced by the activity of microorganisms in an aerobic environment. Follow the process of being broken down into carbon dioxide. Therefore, the carbon dioxide gas generated in the treatment tank contains a slight odor of spoilage of spoilage present inside the treatment tank at that time. In the previously proposed soot treatment apparatus, this carbon dioxide gas There is an inconvenience that an unpleasant odor drifts around the treatment tank from which the gas is released, which makes the user uncomfortable.
[0010]
This inconvenience can be solved by providing ventilation means inside the sink serving as the processing chamber installation room, and discharging the carbon dioxide released to the periphery of the treatment tank to the atmosphere by the operation of the ventilation means. However, in this case, it is necessary to newly install a ventilation means and a communication path for communicating this ventilation means with a predetermined ventilation path, resulting in a complicated overall configuration and an associated increase in product cost. .
[0011]
The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a soot treatment apparatus capable of preventing the release of carbon dioxide gas generated by decomposition of soot and having a bad odor to the periphery of a treatment tank with a simple configuration. And

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below with reference to the drawings showing an embodiment of the present invention. FIG. 1 and FIG. 2 are front sectional views showing an embodiment of a soot processing apparatus (hereinafter referred to as the present invention apparatus) according to the present invention.
[0019]
In the figure, reference numeral 1 denotes a sink provided with a sink 2 at the top thereof, and a drainage opening 20 opened on the bottom surface of the sink 2 is connected to a basin 22 having a drain basket 21 mounted therein. . A drain pipe 23 is connected to the bottom of the water catching portion 22 so as to be located outside the water draining basket 21, and a water spout opening 24 that opens into the inside of the water draining basket 21 is formed substantially at the center.
[0020]
The drainage pipe 23 is a pipe that extends through the bottom surface of the sink 1 and connects the extended end to a sewer (not shown). The middle of the drainage pipe 23 has a U-shape inside the sink 1. It is bent and constitutes an odor stop trap 25 for blocking odor from the sewer. The upper end of the drain pipe 23 is always open to the bottom surface of the soot receiving portion 22, while the soot inlet 24 is normally airtightly closed by a pusher 26 as shown in FIG.
[0021]
Thus, the drainage used for cooking in the sink 2 is first introduced into the draining basket 21 from the drainage port 20, and passes through a number of water holes formed in the peripheral surface of the drainage basket 21, to the receiving part 22. The drain A flows out into the drain pipe 23 and is discharged into the sewer through the drain pipe 23. The dredge A that is put into the drain port 20 together with the drainage is temporarily stored in the drain basket 21 as shown in FIG. The
[0022]
The apparatus of the present invention is installed inside the sink 1 configured as described above, and includes a crusher 3 that crushes the slag A and a treatment tank 4 that receives the smash crushed by the crusher 3.
[0023]
The crusher 3 includes a transfer pipe 30 that is installed on a base 5 that is erected from the inner bottom surface of the sink 1, and a crushing motor 31 that is fixed to the base end of the transfer pipe 30. A transfer screw 32 that is driven by the crushing motor 31 and rotates around the axis within the transfer pipe 30 is provided. On the base end side of the transfer pipe 30, a receiving opening 30a that opens upward is formed, and this receiving opening 30a is connected to the upper side facing the upper part through the connecting pipe 27. Further, a plurality of fixed blades 33 are radially fixed to the discharge port 30b opened at the tip of the transfer tube 30, and the transfer screw 32 facing the discharge port 30b is connected to the tip of the transfer screw 30b. A rotating blade 34 is attached that rotates while sliding on the fixed blade 33 as the shaft 32 rotates.
[0024]
Further, as shown in the figure, the treatment tank 4 is a cylindrical storage container having an opening on the entire surface of one side and the diameter of the other side being reduced toward the end portion. The lid 4a, which is rotatably fitted to each other, is hermetically closed, and a fine support net 4b made of a material having high rigidity and excellent corrosion resistance, such as stainless steel and resin, is stretched over the entire inner surface of the same side. It has become the composition. A pivot shaft 42 protrudes from the support net 4b along the axial center of the treatment tank 4, and the pivot shaft 42 penetrates the lid plate 4a and protrudes to the outside.
[0025]
A support leg 6 is erected on the bottom surface of the sink 1 at an appropriate distance from the base 5, and the treatment tank 4 configured as described above is fitted and fixed to the distal end side of the transfer pipe 30. The end of the reduced diameter side is supported by a bearing 40, and the pivot shaft 42 is supported by a bearing 41 fixed on the support leg 6, and is pivotally supported with its axis substantially horizontal. The front end side of the transfer pipe 30 protrudes into the processing tank 4 from the pivotally supported position by the bearing 40, and the discharge port 30 b at the front end of the transfer pipe 30 is opened inside the processing tank 4. The distal end of the pivot shaft 42 is connected to the output end of the mixing motor 43 fixed to the bottom surface of the sink 1 via a transmission chain 44, and the processing tank 4 has an axial center according to the rotation of the mixing motor 43. It is driven to rotate around.
[0026]
On the other hand, the cover plate 4a that is rotatably fitted to the open end of the processing tank 4 is restricted in rotation by the support leg 6 that supports the same side, and is fixed without following the rotation of the processing tank 4. It is supposed to keep the state. An exhaust hole 46 is formed at the periphery of the cover plate 4a at the lowest position in the fixed state. The exhaust hole 46 is connected to the drain pipe by an exhaust pipe 47 fixed outside the corresponding position. In the middle of 23, more specifically, it is connected downstream of the odor stop trap 25.
[0027]
Inside the processing tank 4, a processing medium B is accommodated in a portion on the diameter reduction side with respect to the support net 4b. The processing medium B is a culture base material that forms an environment suitable for the propagation of various microorganisms (fungi), and for example, wood chips made porous by a predetermined treatment are used. Further, on the inner wall of the processing tank 4, a plurality of flat stirring blades 45, 45... Are inclined at a predetermined angle with respect to the axial center and project inward in the radial direction. When the processing tank 4 rotates, the processing medium B inside the processing tank 4 is stirred in the axial direction and the circumferential direction by the action of the stirring blade 45.
[0028]
In the operation of the apparatus of the present invention configured as described above, the pusher 26 is pulled out when an appropriate amount of tub A is captured in the drain basket 21, and thereby the tub in the drain basket 21 is opened to the tub input 24 that opens. The operation is started by turning on an operation switch (not shown) while introducing A.
[0029]
When the operation switch is turned on, the crushing motor 31 and the mixing motor 43 are driven. In the crushing machine 3, the transfer screw 32 and the rotary blade 34 at the front end of the crushing machine 3 are rotated. The tank 4 itself rotates about the axis, and the processing medium B stored inside is stirred by the action of the stirring blade 45.
[0030]
As shown in FIG. 2, the soot A introduced into the soot inlet 24 reaches the receiving port 30a of the crusher 3 through the connecting pipe 27, and is transferred by the rotation of the transfer screw 32 located below the receiving port 30a. The inside of the tube 30 is transferred toward the tip. At this time, the pusher 26 is used to assist the delivery to the transfer screw 32 by pushing downwardly the kite A introduced into the kite slot 24 as indicated by an arrow in FIG.
[0031]
The spear A that has reached the tip of the transfer screw 32 is finely crushed by the rotating blade 34 rotating at the tip position and the fixed blade 33 that is in sliding contact with the rotary blade 34, and passes through the discharge port 30b at the tip of the transfer tube 30 to the treatment tank. 4 is introduced. At this time, the processing tank 4 is rotationally driven by the mixing motor 43, and the soot A introduced into the processing tank 4 is mixed with the processing medium B being stirred inside the processing tank 4.
[0032]
The operation of the apparatus of the present invention as described above is terminated by stopping the crushing motor 31 and the mixing motor 43 by turning off the operation switch performed at an appropriate timing according to the judgment of the user. This stop does not occur immediately in response to the off operation, but the crushing motor 31 stops first after a predetermined time elapses, and further the mixing motor 43 stops after a predetermined time elapses.
[0033]
As for the delay time until the crushing motor 31 is stopped, the culm A being transferred reaches the tip of the transfer screw 32 at the time when the turning-off operation is performed, and the entire amount of the culm A received by the crusher 3 is reliably crushed. This is necessary for being discharged into the tank 4. Further, the delay time until the mixing motor 43 is stopped is such that the processing tank 4 is rotated by a predetermined number after the discharge of the soot A by the crusher 3 is completed, and the soot A and the processing medium B introduced therein are sufficiently mixed. This is necessary to disperse the soot A in the processing tank 4 without any deviation.
[0034]
The processing tank 4 is kept in a stopped state until the next introduction of the soot A, and during this time, the soot A is decomposed. As described above, the processing medium B stored in the processing tank 4 is a microbial culture substrate that forms an environment suitable for the propagation of microorganisms, and the fragments of cocoon A mixed with the processing medium B are held by itself. To be decomposed by various microorganisms (fungi) and microorganisms already propagated in the treatment medium B.
[0035]
This decomposition is due to the process of rotting 厨 芥 A by the activity of microorganisms in an anaerobic environment and the rotting 厨 芥 A by water (H2 O) and carbon dioxide by the activity of microorganisms in an aerobic environment. The process of decomposing into (CO2) is repeated. The aerobic environment is realized by the air in the upper space of the processing tank 4 being taken into the processing medium B by the rotation of the processing tank 4 that is performed each time the jar A is introduced. This is realized gradually by maintaining the processing tank 4 in a stopped state.
[0036]
That is, in the processing medium B inside the processing tank 4, the microbial activity in an anaerobic environment and the microbial activity in an aerobic environment are balanced by continuously adding 厨 芥 A every day. The soot A that is often generated and mixed with the processing medium B is decomposed into water and carbon dioxide, which are the final products, and disappears completely. In addition, in the case of use in the home, the charging of the bowl A is likely to be irregular, so that the processing tank 4 is rotated every predetermined time regardless of whether the bowl A is inserted or not. It is better to take in the air.
[0037]
As described above, the spoilage of the introduced soot A and the decomposition of the spoiled soot A occur simultaneously in the inside of the treatment tank 4, and the carbon dioxide gas, which is a decomposition product, is contained in the treatment tank 4 at this time. It contains a rotting odor emitted from the rotting potato A. On the other hand, the inside of the processing tank 4 is communicated with the outside by the transfer pipe 30 of the crusher 3 and the exhaust pipe 47 connected to the exhaust hole 46 at the lower peripheral edge of the cover plate 4a. At the normal time, the spout inlet 24 which is the end is airtightly closed by the pusher 26. Accordingly, the carbon dioxide gas generated by the decomposition in the treatment tank 4 flows into the exhaust pipe 47 through the exhaust hole 46 and is discharged into the drain pipe 23 to which the other end of the exhaust pipe 47 is connected. The
[0038]
As described above, the connection position of the exhaust pipe 47 is downstream of the odor stop trap 25 formed in the middle of the drain pipe 23, and the carbon dioxide discharged into the drain pipe 23 does not flow to the sink 2 side. It will be discharged to the sewage side, and the off-flavor contained in the carbon dioxide gas will not leak outside. Further, since carbon dioxide gas is heavier than air, it accumulates in the lower part of the processing tank 4 and is effectively discharged from the exhaust hole 46 opened at the lower peripheral edge of the cover plate 4a as described above. Even when the basket inlet 24 is opened, there is almost no risk of leakage from this opening.
[0039]
On the other hand, a part of the water produced by the decomposition of cocoon A is taken into the treatment medium B, whereby the moisture content of the treatment medium B is adjusted and an environment suitable for further propagation of microorganisms is maintained. . Further, the remaining portion of the generated water collects in the lower part of the treatment tank 4 and flows into the drain pipe 23 through the exhaust hole 46 and the exhaust pipe 47 in the same manner as the carbon dioxide gas, and is discharged into the sewage. In order to enable this flow, the exhaust pipe 47 is an inclined pipe inclined slightly downward toward the drain pipe 23, and the treatment medium B inside the treatment tank 4 flows into the exhaust pipe 47 together with the generated water. In order to prevent this, a filter is attached to the opening of the drain hole 46.
[0040]
In the present embodiment, the processing tank 4 that rotates about the horizontal axis is provided, and the mixture of the soot A and the processing medium B is performed by the rotation of the processing tank 4 itself. It is good also as a structure which carries out the said mixing by rotation of this processing tank 4, and is equipped with the stationary processing tank 4, and is equipped with the stirring blade rotated in this processing tank 4. It is good also as a structure which performs the said mixing, Application of this invention is possible also in these structures, and the same effect is acquired.
[0041]
Further, the configuration of the crusher 3 is not limited to the configuration shown in the present embodiment. For example, like the disposer, the crusher A is crushed by the rotary blade 35 that rotates at a high speed in the horizontal plane facing the claw input port 24. However, the crusher 3 having another configuration such as a configuration in which the resin is sent outward in the radial direction and discharged into the processing tank 4 may be employed.
[0042]
【The invention's effect】
As described above in detail, the apparatus of the present invention includes an exhaust pipe that communicates the inside of the treatment tank in which the decomposition of the soot is performed with the middle of the drainage pipe. The odor contained in this gas is discharged through the drain pipe and is blocked by a trap for odor prevention that is generally provided in the middle of the drain pipe and does not leak to the outside. The present invention has an excellent effect such that the user does not feel uncomfortable due to a strange odor, and this is realized by a simple configuration in which an exhaust pipe is interposed between the treatment tank and the drain pipe. Play.
Furthermore, by providing a control means for stopping the crushing drive means after a predetermined time has elapsed from the operation stop operation, and further stopping the mixing drive means after the predetermined time has passed, the crushing means has been accepted when the operation stop operation has been performed. The entire amount of the soot is reliably crushed and discharged into the processing tank. After discharging the soot by the crushing means, the processing tank is rotated by a predetermined number so that the soot and the processing medium are sufficiently mixed. Has the effect of being distributed evenly inside the treatment tank.
