  It has been conventionally practiced to finely chop raw garbage from home kitchens and canteens, reduce the volume (reducing or reducing the volume) by stirring and drying, and reuse it as organic fertilizer.

JP-A-5-96271 JP 2004-261673 A JP 2001-70921 A JP-A-8-243423

  In Patent Document 1, raw garbage is pulverized, heated and dried in a stirring tank (heating tank). In Patent Document 2, air containing water generated by stirring and drying in a processing tank is condensed into a condensing device (moisture removing means). ) To remove moisture by condensation (condensation). In other words, the raw garbage is stirred and dried as it is, and the air is circulated through a closed system connecting the stirring tank (treatment tank) and the condenser.

  Patent Documents 3 and 4 deal with raw garbage pulverized by a disposer, and both of them release air for drying raw garbage to the atmosphere. That is, in Patent Document 3, a solid content is separated by a solid-liquid separator (400) from a mixed fluid obtained by mixing raw garbage and water pulverized by a disposer (200), and composted by a solid material processing device (600). On the other hand, the separated drainage is subjected to aerobic treatment by natural diffusion of oxygen without using forced ventilation by an air pump.

  Moreover, the thing of patent document 4 heats the garbage which grind | pulverized with the disposer (14) with a heater (40), stirring, and discharges the air containing a water | moisture content from a deodorizing exhaust part (44) outside. Therefore, all of Patent Documents 3 and 4 release drying air containing odors into the atmosphere (atmospheric open type).

  In Patent Documents 1 and 2, garbage is put into a stirring tank (heating tank) as it is, stirred, circulated through a closed air passage that is not open to the atmosphere, and dried. There is a problem that it takes time to make it. In other words, because the garbage is heated while being cut in a stirring tank, it takes time to process large and hard garbage, and in the case of garbage with a lot of moisture, it takes a long time and much heat energy to evaporate the water. Because it is bad.

  In the thing of patent document 3, since solid content isolate | separated with the solid-liquid separator contains much water | moisture content, drying will take time only by stirring in a processing tank. Moreover, since it stirs and composts in the processing tank (610) which solid content was open | released to air | atmosphere, an odor will also be discharge | released to air | atmosphere.

  In the thing of the patent document 4, since the garbage which grind | pulverized with the disposer contains a lot of water, in order to heat and dry this, much heat energy and processing time are required. Also, since the drying air is released to the atmosphere, a strong odor is generated.

  The present invention has been made in view of such circumstances, and can reduce the amount of heat required for drying to improve the thermal efficiency, shorten the processing time of garbage, and does not emit bad odor to the outside. An object of the present invention is to provide a garbage disposal apparatus that can be downsized as a whole and can be rationally arranged.

According to the present invention, a first object is a garbage processing apparatus that dries and contracts garbage, and mechanically separates solids from a mixed fluid obtained by mixing previously crushed garbage and water. A solid-liquid separator that discharges the fluid, a processing tank that stirs and heats the separated solid to evaporate the water, cools the air containing the water evaporated in the processing tank, condenses and discharges the water and condensation condenser to the air circulation path for circulating air between said processing bath and condensation condenser, a drainage path for discharging the fluid component separated in the solid-liquid separator and condensing condenser, the A housing that contains a solid-liquid separator, a processing tank, an air circulation path, and a drainage path, and the condensation condenser is disposed on an outer surface and can be cooled by outside air , and the condensation condenser includes the casing to be disposed and arranged on the rear surface of the rear condenser on the upper surface of the casing the rear condenser Garbage disposal apparatus comprising a ceiling condenser inclined to selfishness lowered, is accomplished by.

  According to the first aspect of the present invention, a slurry-like fluid in which raw garbage previously pulverized by a disposer or the like and water are mixed (a fluid in which fixed particles are mixed in a liquid; When solids with a large amount of moisture are dried by heating, the solids are mechanically separated from the solid fluid by a solid-liquid separator and only the solids with sufficiently reduced moisture are dried in the treatment tank. In comparison with this, the heat energy required for the evaporation of moisture is greatly reduced. For this reason, the thermal efficiency can be improved.

  Further, since the amount of water to be evaporated is small, the processing time can be shortened. Here, the air containing water vapor evaporated in the treatment tank circulates in the closed air flow path connecting to the dew condensation condenser, so that no bad smell of garbage is released into the atmosphere. Furthermore, since only the solid content from which a large amount of water has been removed is dried by the solid-liquid separator, the treatment tank for drying can be downsized, and as a result, the entire apparatus can be downsized. Furthermore, since the dew condensation condenser is disposed on the outer surface of the housing, it has good cooling performance by the outside air and can efficiently condense the water vapor contained in the circulating air, thus allowing rational arrangement of each member. .

  The mixed fluid to be charged into the solid-liquid separator is preferably obtained by sufficiently finely pulverizing raw garbage put in the disposer together with a sufficient amount of water with the disposer. This is because the solid content of the garbage is sufficiently finely pulverized, so that the processing time can be shortened by efficiently stirring and heating the solid content in the treatment tank.

Since the condensation condenser is installed on the vertical outer surface ( upper surface and rear surface ) of the casing, the condensation condenser is efficiently cooled by the outside air outside the casing, promoting the condensation of moisture and reducing the condensed water downward. Can be dropped . The ceiling condenser may be divided into a plurality.

For example, the ceiling condenser may be further divided into an air forward path and a return path (Claim 2 ). That is, it is divided into an outbound ceiling condenser that guides air from the treatment tank to the back condenser and a return ceiling condenser that leads from the back condenser to the treatment tank. In this case, the configuration of the ceiling condenser is simplified.

The air circulation path can circulate the air in the processing tank in parallel between the ceiling condenser and the back condenser (Claim 3 ) or circulate in series (Claim 4 ). According to the former, which circulates in parallel, it is possible to efficiently cope with fluctuations in the amount of circulating air. That is, the load on the ceiling condenser and the rear condenser can be equalized or optimized. Moreover, when automatically controlling the air flow rate of the blower fan for circulating air according to the processing amount and water content of the treatment tank, it is easy to cope with an increase in air blowing resistance. For example, it is conceivable to appropriately change the air flow to each condenser by changing the air flow. According to the latter, which is circulated in series, it is possible to increase the overall length of the air flow path to promote cooling, and to promote the removal of water vapor and the drying of air. For this reason, drying of the garbage of a processing tank can be accelerated | stimulated.

Between the processing bath and the ceiling condenser, the forward and return air circulation path can be interposed a duct having a respective radiating surface (claim 5). A duct may be interposed in the air circulation path between the ceiling condenser and the back condenser (Claim 6 ). In these cases, air can be additionally cooled by the duct, and drying of the garbage in the treatment tank can be further promoted.

The treatment tank is placed in the front lower part of the case, its opening / closing lid is placed on the front of the case, and the condensation condenser is placed on the other outer surface of the case. The workability is good and convenient for discharging the solid content to the outside (Claim 7 ). In this case, the solid-liquid separator is preferably arranged at the rear upper part in the housing, and the solid content separated here is guided (dropped) to the processing tank at the shortest distance, and the back condenser is preferably arranged at the top of the back. . In addition, it is preferable that the fluid component of the solid-liquid separation and the fluid component of the condensation condenser (condensed water) are collected in a drainage passage and discharged (claim 8 ).

  This is because the fluid components (drainage and drainage) that come out of the solid-liquid separator and the condensation condenser are combined and discharged in the drainage path, so that the number of outlets is reduced and external piping can be simplified. . In this case, the drainage of the back condenser is preferably guided to the drainage path through a one-way valve. This is because a large amount of the drainage (fluid) of the solid-liquid separator is discharged immediately after the mixed fluid is charged, so that it does not flow back to the back condenser. In addition, since the effluent discharged from the solid-liquid separator has a strong odor, it is particularly undesirable that the odor is mixed into the air circulating through the treatment tank and the condensation condenser.

  In addition, the inlet that supplies the mixed fluid to the solid-liquid separator and the drainage outlet of the drainage channel are opened on both the left and right sides of the housing, respectively, and use the one that is convenient for external piping, It is better to close the unused opening with a cap. Depending on the installation location of the chassis, the direction of connection to the disposer and the direction of connection to the sewage drain are different. This is because the degree of freedom in selection increases.

  1-8, the code | symbol 10 is a substantially box-shaped housing | casing. A processing tank 12 is accommodated in the front lower part inside the casing 10, and a solid-liquid separator 14 is accommodated in the rear upper part inside the casing 10. Further, the upper surface of the casing 10, that is, the ceiling surface, is formed by a ceiling condenser 16, and a rear condenser 18 is attached to the rear surface, that is, the rear surface.

  As shown in FIGS. 6 and 7, the treatment tank 12 has a substantially elliptic cylinder 20. The cylinder 20 has an ellipse major axis in the up-down direction, an ellipse minor axis in the horizontal direction, and is long in the front-rear direction. The rear end of the cylinder 20 is closed by a rear end plate 20 </ b> A (FIG. 7), the front end opens on the front surface (front surface) of the housing 10, and the opening can be opened and closed by a lid plate 22. That is, the lid plate 22 can be fixed to the front surface of the housing 10 by the three lock fittings 24.

  A reduction gear 26 and an electric motor 28 are attached to the rear surface of the cylinder 20 (the rear surface of the rear end plate 20A) (FIG. 7). The rotation of the motor 28 is decelerated by the speed reducer 26 and rotationally drives the rotary shaft 30 that passes through the cylinder 20 in the front-rear direction. An appropriate number of stirring rods (or stirring blades) 32 are fixed to the rotating shaft 30. The cylinder 20 is fed with the solid content of garbage from the solid-liquid separator 14 described later, and this solid content is stirred by the stirring rod 32. The cylinder 20 is heated by an electric heater 34 (FIGS. 7 and 8), and the solid content is heated by this heat.

  The solid-liquid separator 14 is accommodated in the rear upper portion of the housing 10. That is, a substantially conical case 36 attached to the upper surface of the rear portion of the processing tank 12 opens into the cylinder 20 of the processing tank 12. A part of the inner surface of the case 36 is a substantially annular outer frame 38. An inner rotating body 40 that rotates about a rotation axis that is horizontal in the left-right direction is accommodated inside the outer frame body 38. The inner rotating body 40 is rotationally driven by a motor 42 with a reduction gear (FIGS. 3 and 6) in the counterclockwise direction (arrow A direction) in FIG.

  The inner rotator 40 is formed of a large number of annular thin plates stacked with a slight gap in the direction of the rotation axis (left and right horizontal direction). Each thin plate protrudes in the outer peripheral direction at predetermined intervals, and a plurality of protrusions 44 that slide on the inner peripheral surface of the outer frame 38 are formed on the outer periphery of the inner rotating body 40 in which the thin plates are laminated.

  In FIG. 8, reference numeral 46 denotes a kitchen sink (sink), and a disposer 48 is attached to the sink 46. Kitchen garbage is put into the disposer 48 together with tap water, and is finely pulverized by a rotating blade (not shown) of the disposer 48. As a result, fine garbage and water are mixed to form a slurry-like fluid (mixed fluid). This slurry-like mixed fluid is guided to the solid-liquid separator 14.

  That is, the mixed fluid inlet 50 located at the front lower side of the inner rotating body 40 is opened in the case 36 of the solid-liquid separator 14 as shown in FIG. The mixed fluid entering the case 36 from the inlet 50 is transferred in the direction of arrow A along the inner peripheral surface of the outer frame 38 by the protrusion 44 of the inner rotating body 40. At this time, a gap formed between the thin plates of the inner rotating body 40 functions as a filter, and fluid components such as moisture and oil contained in the mixed fluid flow into the inner rotating body 40 (center side). That is, the mixed fluid is mechanically efficiently filtered by the inner rotating body 40.

  A fluid discharge port 52 that opens to the inner side (center side) of the inner rotating body 40 is provided at the lower left side of the case 36 (FIG. 7). The fluid component filtered by the inner rotating body 40 flows out from the fluid component discharge port 52 to one branch path of a substantially U-shaped drainage pipe 54 serving as a drainage path.

The case 36 of the solid-liquid separator 14 is opened from above in the rear upper surface of the processing tank 12, and this opening serves as a solid content outlet 56. A guide member 58 is attached to a position facing the solid content outlet 56 above the case 36. This guide member 58 is formed by laminating thin circular plates in a side view with a gap therebetween, and the tip on the side opposite to arrow A (the side opposite to the rotational direction of the inner rotating body 40) is in the gap of the thin plate of the inner rotating body 40. I have entered. For this reason, by the rotation of the inner rotating body 40, the solid content that has entered the gap between the thin plates is dug out by the outer peripheral surface of the guide member 58 and guided to the solid content discharge port 56 .

  A diaphragm member 60 that forms a diaphragm portion together with the guide member 58 is in elastic contact with the outer peripheral surface of the guide member 58. The throttle member 60 is supported by a fulcrum 62 on the side opposite to the arrow A, and the tip (movable end) on the arrow A side is pressed against the outer peripheral surface of the guide member 58 by a spring (not shown). For this reason, the solid content transferred by the inner rotating body 40 and remaining in the gap between the inner and outer rotating bodies 40 and the outer frame body 38 during the filtration process is guided to the outer peripheral surface of the guide member 58 and pushes the throttle member 60 open. It is discharged to the discharge port 56. At this time, moisture (fluid content) is squeezed out by the squeezing member 60, and the solid content enters the treatment tank 12 with the moisture (liquid content) further reduced.

  Since this solid content is stirred and heated in the treatment tank 12, the moisture evaporates. The air containing a large amount of water vapor circulates through an air circulation path 64 that connects between the treatment tank 12 and the condensation condensers 16 and 18. That is, this air circulates in a passage 64 that is not open (closed) to the atmosphere. Next, the electric circuit 64 will be described.

  On the upper surface of the front portion of the cylinder 20 of the treatment tank 12, an air outlet pipe 66 stands on the right side and an air inlet pipe 68 stands on the left side when viewed from the front (see FIGS. 3, 4, and 6). A blower fan 70 is incorporated in the air outlet pipe 66. The upper ends of the air outlet pipe 66 and the air inlet pipe 68 are connected to the front lower surface of the ceiling condenser 16. That is, when the ceiling condenser 16 is attached to the housing 10 from above, the upper ends of the air outlet pipe 66 and the air inlet pipe 68 are airtightly connected to the lower surface of the ceiling condenser 16 through the sealing material. The ceiling condenser 16 is formed by integrally forming the right forward ceiling condenser 16A and the left backward ceiling condenser 16B, whose air passages are independent from each other (FIG. 8), and can be made by, for example, resin blow molding. it can.

  The ceiling condenser 16 is inclined so that the front part is high and the rear part is low (that is, it descends toward the rear condenser 18), and the liquid (condensed water) condensed (condensed) here is transferred to the rear condenser 18. It is easy to flow out. The ceiling condenser 16 is provided with an opening 72 through which the upper part of the solid-liquid separator 14 enters between the forward and backward ceiling condensers 16A and 16B (FIGS. 3, 4, 5, and 7). Is covered with an upper face decorative cover 74. A front decorative cover 76 is attached in front of the ceiling condenser 16.

The rear lower surfaces of the ceiling condensers 16A and 16B are connected to the upper part of the rear condenser 18 by L-shaped connecting pipes 78 (78A and 78B). The back condenser 18 is made by, for example, resin blow molding, and is attached to a metal plate 10A (FIGS. 2 and 5) that is the back surface of the housing 10. The rear condenser 18 has air passages on both sides, and the front air passage faces the inside of the housing 10 from an opening provided in the metal plate 10A.

  A drainage port 18A is provided in the lower part of the back condenser 18, and a one-way valve 80 is connected vertically. The lower end of the one-way valve 80 is connected to the other branch path of the U-shaped drainage pipe 54. For this reason, the water condensed by the ceiling condenser 16 enters the back condenser 18, merges with the water newly condensed by the back condenser 18, and flows into the drain pipe 54 from the one-way valve 80. Here, the liquid discharge port 18 </ b> A is located below the fluid component discharge port 52 of the solid-liquid separator 14.

  Pipes opened on the left and right side surfaces of the casing 10 pass through the branch path on the one-way valve 80 side of the drain pipe 54, and a pair of drain ports 82 (82A, 82A, 82B). The drainage pipe 54 is substantially U-shaped, and the malodor of the drainage (fluid component) of the solid-liquid separator 14 and the malodor that has passed through the solid-liquid separator 14 from the treatment tank 12 flow out to the drainage port 82. It is a trap that prevents this.

  The mixed fluid inflow ports 50 are formed at both ends of a pipe that penetrates the case 36 in the left-right direction of the casing 10, and both ends of the pipe are opened on the left and right side surfaces of the casing 10. As described above, since the inlet 50 and the drain port 82 are opened on both the left and right side surfaces of the housing 10 and can be opened and closed by closing with caps, it is easy to connect the disposer 48 and the sewage port depending on the installation location of the housing 10. The inflow port 50 and the drainage port 82 can be selected and used.

  Next, the operation of this garbage disposal apparatus will be described. The mixed fluid exiting the disposer 48 enters the solid-liquid separator 14. The mixed fluid is transferred between the outer frame 38 and the inner rotator 40 by the protrusion 44, and the mixed fluid is filtered by the inner rotator 40 during this time. The solid content is further transferred and sent to the outside along the outer periphery of the guide member 58. At this time, the solid content is sandwiched between the throttle member 60 and the fluid content is further squeezed out. The fluid component flows into the inner rotary body 40 and enters the U-shaped drainage pipe 54 from the fluid component discharge port 52.

  The separated solid content enters the cylinder 20 of the treatment tank 12 from the solid content discharge port 56. Here, the solid content is heated by the heater 34 while being stirred by the stirring rod 32. For this reason, the water | moisture content contained in solid content evaporates. The air containing the steam is sent to the air circulation path 64 by the blower fan 70, and circulates back to the cylinder 20 through the forward ceiling condenser 16A, the back condenser 18, and the backward ceiling condenser 16B. This air is cooled by the condensers 16 and 18, and as a result, the water vapor is condensed and becomes liquid (water) and collects in the lower part of the rear condenser 18. This liquid (water) enters the U-shaped drainage pipe 54 through the one-way valve 80. The liquid that has entered the U-shaped drainage pipe 54 is discharged from the drainage port 82 to the sewer together with the fluid discharged from the solid-liquid separator 14.

  When an appropriate amount of the solid content dried in the cylinder 20 of the treatment tank 12 is accumulated, the lid plate 22 is opened and discharged to the outside. This solid content is used as organic fertilizer, livestock feed and the like.

FIG. 13 is a conceptual diagram showing the air circulation path 164 and the drainage path 54, and FIG. 14 is an explanatory diagram of the air circulation path 164. In this embodiment, the ceiling condenser 116 and the back condenser 118 are connected in parallel, and a duct 190 (190A, 190B) having a heat radiation surface is interposed in the air inflow path and the air outflow path of the back condenser 118. It is a thing. In these FIGS. 9-14, since the same code | symbol was attached | subjected to FIGS. 1-8 of the said Example 1, those description is not repeated.

  In the second embodiment, the ceiling condenser 116 is inclined such that the front part is high and the rear part descends toward the rear condenser 118, and the front part branches left and right in the plan view and the rear part communicates. A substantially U-shaped air passage is formed (see FIGS. 11 and 13). The air passage of the ceiling condenser 16 of the first embodiment is divided into left and right parts and independent from each other, whereas the ceiling condenser 116 of the second embodiment is not divided. A drain pipe 192 is connected to the rear lower surface of the ceiling condenser 116, and the drain pipe 192 is a U-shaped drain pipe (trap) via a one-way valve 194 for condensing water condensed by the ceiling condenser 116. ) 54 (FIG. 11).

  The ducts 190 </ b> A and 190 </ b> B send the air passing through the inside while cooling the surface, and are long in the front-rear direction below the ceiling condenser 116, and are arranged side by side. An air outlet pipe 166 and an air inlet pipe 168 pass through the front portions of the ducts 190A and 190B, respectively. The upper ends of the air outlet pipe 166 and the air inlet pipe 168 are connected to the front lower surface of the ceiling condenser 116. The air outlet pipe 166 and the air inlet pipe 168 are formed with openings 166A and 168A at intervals in the circumferential direction as shown in FIGS. The openings 166A and 168A communicate with the ducts 190A and 190B in a state where the air outlet pipe 166 and the air inlet pipe 168 are inserted into the ducts 190A and 190B (see FIG. 14). The rear portions of the ducts 190A and 190B are connected to the back condenser 18 via connection pipes 178 (178A and 178B).

  When the ducts 190A and 190B are assembled to the housing 10 from above, as shown in FIG. 12, the upper ends of the air outlet pipe 166 and the air inlet pipe 168 passing through the ducts 190A and 190B from below are directed upward. Open. These openings 166B and 168B are connected to each other while maintaining airtightness by being pressed by the air inlet and the electric outlet of the ceiling condenser 116 when the ceiling condenser 116 is attached to the housing 10 from above. The air outlet pipe 166 and the air inlet pipe 168 are connected to the ducts 190A and 190B and the ceiling condenser 116 via an appropriate sealing material so as to prevent air leakage. In FIG. 12, the left and right side surfaces of the housing 10 are formed of a side frame 10B made of a metal plate and a resin cover 10C overlaid thereon.

  In the second embodiment, as shown in FIG. 14, a part of the air circulated from the processing tank 12 to the ceiling condenser 116 is branched into ducts 190 </ b> A and 190 </ b> B by the air outlet pipe 166 and the air inlet pipe 168. Circulate to condenser 118. That is, the air in the processing tank 12 circulates in parallel with the ceiling condenser 116 and the back condenser 118. At this time, since the duct 190 </ b> A in the air forward path cools the air passing therethrough, it is possible to improve the water vapor condensation performance by the back condenser 118. Further, the duct 190B on the return path further cools the air exiting the back condenser 118 and promotes condensation of water vapor.

  The water condensed by the ceiling condenser 116 flows down the drainage pipe 192 and the one-way valve 194, joins with the water passing through the one-way valve 80 from the back condenser 118, and enters the U-shaped drainage pipe 54. Led. The water condensed in the ducts 190A and 190B flows to the back side due to the inclination of the ducts 190A and 190B, and enters the back condenser 118 through the connecting pipes 178A and 178B. Then, it flows down to the one-way valve 80 and the drain pipe 54 while being mixed with the water condensed by the back condenser 118.

  According to this embodiment, since the air in the processing tank 12 is circulated in parallel to the two condensers 116 and 118, the load on both condensers 116 and 118 can be equalized or optimized, and the water vapor discharged from the processing tank 12 It can respond efficiently to fluctuations in volume and circulating air flow.

  FIG. 15 is an explanatory diagram of an air circulation path 264 of another embodiment. In this third embodiment, the air passing through the ceiling condenser 116 from the processing tank 12 is guided to the back condenser 118 through the duct 290A, and the air leaving the back condenser 118 is supplied to the processing tank 12 through another duct 290B. Lead. That is, the ceiling condenser 116, the back condenser 118, and the ducts 290A and 290B are connected in series.

  According to the third embodiment, the total length of the air flow path is significantly longer than those of the first and second embodiments. For this reason, the air can be sufficiently cooled to sufficiently promote the condensation of water vapor. That is, the processing time (drying time) of the processing tank 12 can be shortened by reducing the water vapor of the air returning to the processing tank 12 to promote drying.
