Description

  The present invention relates to an apparatus for supplying garbage-like waste, and more particularly to an apparatus for supplying garbage-like waste to a recycling system that recovers valuable resources by methane fermentation.

  Garbage discharged from kitchens of general households, hotel / restaurant kitchens, food production residue discharged from food factories, etc., agricultural / livestock / fisheries facilities, forestry / dismantling facilities, paper / pulp factories, etc. Recycling technology for recovering valuable resources using organic organic waste such as animal and vegetable residues (hereinafter referred to as garbage-like waste) as a material has been developed and is being promoted. For example, as shown in FIG. 9, Patent Document 1 discloses a bioreactor 55 that decomposes garbage-like waste A into biogas G and residual organic matter E by methane fermentation, and converts biogas G into electric power and high-temperature water. Fuel cell 60 and secondary treatment facility 56 for converting residual organic matter E into fertilizer / feed material, and recovering electrical energy, thermal energy, and fertilizer / feed material from garbage-like waste A as valuable resources A recycling system is disclosed.

  However, there is a case where foreign matter such as plastic, metal pieces, wood pieces and the like are mixed in the garbage-like waste A, and it is necessary to separate the mixed foreign matters in the waste A for recycling. Moreover, the size and shape of the organic matter in the garbage-like waste A are various, and it is necessary to adjust the organic matter in the waste A to an appropriate concentration and particle size when recycling. The recycling system of FIG. 9 separates contaminated foreign substances in garbage-like waste A and adjusts the concentration and particle size of organic substances (hereinafter, these processes may be collectively referred to as “pretreatment”). For this reason, a foreign matter separation device 51, a pulverizer 52, and a slurry tank 53 are provided.

  Patent Documents 2 to 4 disclose a conventional foreign matter sorting apparatus 51 for pretreatment. For example, in Patent Document 3, as shown in FIGS. 5 to 8, a cylindrical body 2 in which a part of the cross section of the peripheral wall 3 is arc-shaped (consisting of an arc-shaped bottom wall 3 a and a non-arc-shaped top wall 3 b, see FIGS. 7 and 8). A plurality of plate-like blades 6a having a rotating shaft 5 extending along the central axis of the arc-shaped bottom wall 3a, and a protruding edge 7 fixed along the rotating shaft 5 and facing the arc-shaped bottom wall 3a with a minute gap therebetween. , 6b, 6c, 6d (hereinafter sometimes referred to as the rotor blade 6) is disclosed. A plurality of through-holes 10 are formed in the arc-shaped bottom wall 3a, and an air flow path 12 is formed between the non-arc-shaped top wall 3b of the cylindrical body 2 and the projecting edge 7 of the rotor blade 6, and the air in the air flow path 12 is formed. Air guide plates 15a, 15b, 15c for guiding the flow W (see FIG. 7) in the longitudinal direction of the cylinder are attached to the non-arc shaped top wall 3b. Further, an intake 16a for garbage-like waste A is bored at a portion of the cylindrical peripheral wall 3 facing the upstream side of the air flow W in a direction crossing the central axis of the cylindrical body 2.

  The foreign matter separating apparatus 51 of FIGS. 5 to 8 takes the garbage-like waste A into the cylinder 2 in a direction crossing the rotary shaft 5 from the inlet 16a, and crushes and discards the waste A by the rotation of the rotary blade 6. The foreign matter B in the object A is separated. The separated foreign matter B is carried out of the cylindrical body 2 from the downstream discharge port 18 and the discharge duct 19 by the air flow W generated by the rotation of the rotary blade 6. The crushed waste (hereinafter sometimes referred to as waste paste) C after the foreign matter separation is further finely crushed between the tip edge 7 of the rotor blade 6 and the inner surface of the arc-shaped bottom wall 3a and discharged from the pores 10. Then, it is collected in a paste hopper 67 (see FIG. 10) or the like provided below the sorter 5. For example, the receiving hopper 13 is installed in the intake port 16, and the garbage-like waste A received in the receiving hopper 13 is continuously taken into the cylinder 2 by gravity.

  FIG. 10 shows an example of a conventional pretreatment system for garbage-like waste A packed in a plastic resin bag or container (hereinafter simply referred to as a bag). For example, bag-like garbage-like waste A collected by public services is stored in the storage hopper 36, and is sequentially sent out to the constant-feed bag breaker 14 by an extrusion screw (conveyor) 43 provided at the bottom, according to the sorting capacity. A predetermined amount is taken into the receiving hopper 13 of the foreign matter sorting apparatus 51. A bag of garbage-like waste A is broken by the fixed supply bag breaking machine 14 and foreign matter B such as bag fragments and tableware is separated from the waste A by the foreign matter sorting device 51. The waste paste C collected in the paste hopper 67 of the foreign matter separation device 51 is discharged by, for example, a paste discharge screw 67a and sent to the slurry tank 53 via a transfer device 68 such as a paste pump and a paste transfer line 70. In the slurry tank 53, equal to or twice the amount of water is mixed to adjust the organic matter concentration of the waste paste C, and further circulated through the circulation line 52a with the pulverizer 52 so that the organic matter in the paste C is 1 mm or less on average. Is pulverized to a particle size of about several hundred microns to form a waste slurry S. The waste slurry S with the organic substance concentration and particle size adjusted is sent to the bioreactor 55 via the slurry pump 54 and the slurry supply line 71, and used for, for example, the recycling process of FIG.

Japanese Patent No. 3064272 JP 2000-167426 A JP 2002-177888 A JP 2004-154624 A JP 2005-138090 A

  However, in the conventional pretreatment system shown in FIG. 10, the foreign matter separation device 51, the transfer device 68, the pulverizer 52, and the slurry tank 53 each require an installation space, so that the site area is installed in a small area. It is difficult. Further, since the garbage-like waste A is taken from the storage hopper 36 into the foreign matter separation device 51 by using gravity, a plurality of devices such as the extrusion screw 43, the quantitative supply bag breaker 14, and the receiving hopper 13 are stacked in the gravity direction. It is necessary and it is difficult to install in places with height restrictions. There is a need for a compact pre-processing system, particularly in small-scale recycling systems.

  10 transfers the waste paste C having a relatively high viscosity from the foreign matter separating device 51 to the slurry tank 53, so that the transfer device 68 and the paste transfer line 70 in the meantime are blocked by the waste paste C. The problem of interruption of operation due to blockage was experienced. In this case, clogging can be avoided by diluting the waste paste C before transfer with water to reduce the viscosity. However, diluting the waste paste C reduces the amount of biogas generated per unit weight in the bioreactor 55 and There is a risk that the processing efficiency of resource recycling will decrease. Development of a pretreatment system that enables continuous operation without reducing the recycling efficiency is desired.

  Accordingly, an object of the present invention is to provide a garbage-like waste supply apparatus that is compact and can be continuously operated.

  Referring to the embodiment of FIGS. 1 and 2, the garbage-like waste supply apparatus of the present invention has a waste-like waste A intake 16 formed at one end in the longitudinal direction and the other end of the waste A. A cylindrical body 2 in which a discharge port 18 for mixed foreign matter B is bored, fixed to a rotary shaft 5 on the longitudinal axis inside the cylindrical body, and a radial tip is opposed to the bottom wall 3a of the cylindrical body 2 through a minute gap. The rotating blade 6 (see also FIGS. 5 to 8), the pore 10 which is pierced between one end of the bottom wall 3a of the cylinder 2 and the discharge port 18 and drops the waste C crushed by the rotation of the rotating blade 6 The storage tank 26 opened below the group of pores 10 and joined integrally with the cylindrical body 2, the stirrer 27 for stirring the waste C in the tank 26, and the waste C in the tank 28 are externally attached. It is provided with a waste circulation path 28 that is circulated through the pulverizer 29 to form a slurry, and a slurry supply port 30 provided in the tank 26 or the circulation path 28, and the taken-in waste-like waste A is mixed with foreign matter. And supplies as not milled slurry S.

  Preferably, a water supply nozzle 24 is provided on the top wall 3b or the side wall of the cylindrical body 2. More preferably, the intake port 16 is formed in one end surface of the cylindrical body 2 in the longitudinal direction, and a press-fitting device 33 for press-fitting the garbage-like waste A into the intake port 16 in parallel with the rotating shaft 5 of the cylindrical body 2 is provided. When the garbage-like waste A is in a bag, as shown in the figure, a hopper 36 that stores the garbage-like waste A in a bag and a break that extends to the bottom of the hopper 36 and continues to the press-fitting device 33 An extruder 37 with a bag function can be provided.

  The apparatus for supplying garbage-like waste according to the present invention has a cylindrical body for separating foreign substances of garbage-like waste A and a storage tank for pulverization, which are combined together in the upper and lower sides, and mixed in the garbage-like waste introduced. Foreign matter is separated in the cylinder, the waste paste after foreign matter separation is dropped to the storage tank through the pores on the bottom wall of the cylinder, and the waste paste in the storage tank is circulated to the pulverizer while stirring. Since it is finely pulverized and supplied as a finely pulverized slurry with no foreign matter mixed therein, the following remarkable effects can be obtained.

(A) Since the foreign substance separating device and the slurry tank, which have been independent of each other, can be integrated, it is possible to greatly reduce the required installation area of the pretreatment system and reduce the size.
(B) The transfer of the waste paste after the foreign matter separation can be omitted, and the paste transfer device or the like is not required, so that the operating cost (running cost) can be kept small.
(C) Since the transfer line for the waste paste having a relatively high viscosity can be omitted, there is no possibility of interruption of operation due to the blockage of the transfer line, and continuous operation of pretreatment becomes possible.
(D) By providing a water supply nozzle in the cylinder and supplying water, it is possible to adjust the supply concentration of the finely pulverized slurry and improve the efficiency of foreign matter separation by adjusting the moisture in the garbage-like waste.
(E) Garbage-like waste can be press-fitted into one end in the longitudinal direction of the cylinder, and a compact pre-processing system with a smaller vertical height than conventional gravity-based pre-processing systems can be achieved. .
(F) By sending the garbage-like wastes by pressure, it is not necessary to arrange the hopper, the cylindrical body, and the slurry tank in the direction of gravity, and the pretreatment system can be freely designed.

  1 and 2 show an embodiment of a supply apparatus 1 for garbage-like waste A of the present invention. The supply device 1 in the illustrated example has a cylindrical body 2 for separating foreign substances contained in garbage-like waste A, and a storage tank 26 integrally coupled to the lower part thereof. The cylindrical body 2 can be the same as the conventional foreign matter sorting apparatus 51 (see FIGS. 5 to 8). For example, the lower half of the arc-shaped cross section is the bottom wall 3a, the upper half of the cross section is expanded outward in the radial direction and the top half 3b is the top wall 3b, and both halves are joined to form a cylinder. A cylindrical body 2 is used. An intake port 16 for garbage-like waste A is bored at one end in the longitudinal direction of the cylinder 2 and an outlet 18 for foreign matter B contained in the waste A is bored at the other end. A plurality of pores 10 are formed between one end of the bottom wall 3 a of the cylinder 2 and the discharge port 18, and a storage tank 26 is opened below the pores 10 so as to be integrally joined to the cylinder 2. It is desirable that the storage tank 26 is airtightly coupled to the cylindrical body 2 so that odors and the like of garbage are not leaked.

  In the illustrated example, the intake 16 is drilled in one end surface in the longitudinal direction of the cylinder 2, the press-fitting device 33 is attached to the inlet 16, and garbage-like waste A is pressed into the cylinder 2 in parallel with the rotary shaft 5. Yes. An example of the press-fitting device 33 is a single-screw screw conveyor that feeds the waste A by rotating a rotating shaft 34 with a spiral feed blade 34a (see FIG. 2) by a driving device 35. However, when the waste A is taken in by gravity, the intake 16 may be provided in the top wall 3b of the cylindrical body 2 in a direction crossing the rotating shaft 5 (see FIGS. 5 to 8). When the waste A is press-fitted as in the illustrated example, the position of the intake port 16 can be arbitrarily selected within a range that does not overlap with the longitudinal axis of the cylinder 2, and when it is taken in using gravity. In comparison, the height in the vertical direction can be reduced. The discharge port 18 is preferably provided in the bottom wall 3a at the other end of the cylindrical body 2. For example, as shown in FIG. By providing a discharge port 18 as wide as possible in the bottom wall 3a of the cylinder 2, foreign matter B can be discharged not only by the air flow W described later but also by the action of dropping due to gravity. Prevention of stagnation and blockage of the discharge port 18 can be expected.

  Inside the cylindrical body 2, as in the conventional foreign matter sorting device 51 (see FIGS. 5 to 8), a rotary shaft 5 is provided along the longitudinal axis (for example, the central axis of the arc-shaped bottom wall 3 a). 5, the radial tip edge 7 fixes the rotary blade 6 facing the arcuate bottom wall 3a through a minute gap. Further, an air flow path 12 extending in the longitudinal direction of the cylindrical body 2 is formed between the top wall 3b bulging outward and the rotation region of the rotor blade 6 (see also FIG. 7). When the rotor blade 6 rotates, the garbage-like waste A is crushed to the extent that it can be discharged from the pores 10 in the minute gap between the rotating region of the rotor blade 6 and the arcuate bottom wall 3a. An air flow W from the intake port 16 toward the discharge port 18 is formed. In order to avoid crushing of the foreign matter B, for example, as shown in FIG. 6, an elastic plate 8 such as a rubber plate may be attached to the protruding edge 7 of the rotary blade 6.

  In order to form an air flow W from the intake port 16 toward the discharge port 18 in the air flow path 12 in the cylindrical body 2, as shown in FIGS. An intake vane 22 (see FIG. 6) is attached to the end of the rotary shaft 5 or the rotary blade 6 on the intake port 41 side, and the wind guide is directed to the inner surface of the top wall 3b of the cylinder 2 so as to intersect the rotary shaft 5 Install the plate 15. The intake vanes 22 are attached to the rotor blades 6 while being inclined at a predetermined angle δ (for example, about 10 to 30 degrees), and take in the air flow W from the intake ports 41 according to the electric fan principle during rotation. Further, the residence time of the air flow W in the cylindrical body 2 can be adjusted by about 20% by adjusting the number and direction of the air guide plates 15 (angle with respect to the rotating shaft 5). However, when the garbage-like waste A is pumped from the intake 16 at one end of the cylinder 2 as shown in FIG. 1, air can be taken into the cylinder 2 from the intake 16. Can be omitted.

  In the separation process, the rotary shaft 5 is connected to an appropriate drive device (for example, an electric motor) 9 and the cylinder 5 is rotated from the intake port 16 by the press-fitting device 33 while rotating the rotary shaft 5 at a rotational speed of, for example, about 500 to 600 revolutions per minute. The garbage-like waste A is pumped into the body 2. The waste A thrown into the cylinder 2 is stirred and crushed by the rotary blade 6 that rotates together with the rotary shaft 5 and separated into the foreign matter B and the waste paste C. The separated foreign matter B is sent to the discharge port 18 side by the air flow W formed in the air flow path 12, and is discharged from the discharge port 18 by the air flow W and gravity. Further, the waste paste C after the foreign matter separation falls on the bottom wall 3a of the cylindrical body 2, and is further finely crushed in the minute gap between the protruding edge 7 of the rotary blade 6 and the cylindrical bottom wall 3a. Falls directly into the storage tank 26. The pumping speed to the intake port 16 and the rotating speed of the rotary shaft 5 can be adjusted according to the type and state of the waste A so that the foreign matter B can be reliably separated.

  The storage tank 26 in the illustrated example includes a stirrer 27 that stirs the waste paste C that has fallen into the tank 26, an external pulverizer 29, and sends the waste paste C in the tank 28 to the pulverizer 29. 29 and a waste circulation path 28 for circulating the output paste C back to the tank 28. The crusher 29 in the illustrated example is combined with a pump that extracts the waste paste C from the tank 28 and circulates it through the circulation path 28. The waste paste C dropped in the storage tank 26 is uniformly stirred by the stirring blade 27a of the stirrer 27, for example, and is passed through the circulation path 28 once or repeatedly to a required particle size, for example, about several hundred microns. To a slurry S. The finely pulverized slurry S is supplied to the outside of the apparatus by opening a valve 31 of a supply port 30 provided in the tank 26, for example. The supply port 30 may be provided in the circulation path 28 through an appropriate switching valve.

  In order to dilute the waste paste C to a required concentration, the storage tank 26 is appropriately supplied with diluted water. In the illustrated example, a water supply nozzle 24 is provided on the top wall 3b or the side wall of the cylindrical body 2, and water is supplied from the water supply nozzle 24 to the storage tank 26 through the pores 10. By providing the water supply nozzle 24 not in the storage tank 26 but in the cylinder 2, not only the dilution of the paste C but also the water in the garbage-like waste A taken in from the intake port 16 is adjusted by the water supply from the water supply nozzle 24. Is possible. For example, the sticky waste A may block the pores 10 of the cylindrical body 2. However, if the viscosity is lowered by adjusting the moisture by supplying water, the pores 10 can be blocked. Further, the waste A having extremely low moisture can be expected to be efficiently separated from the foreign matter B if it is heavier by water supply.

  Further, the water supply nozzle 24 can be used to clean the inside of the cylinder 2 after the completion of the separation work. If the water supply nozzle 24 is a hot water or steam nozzle for supplying hot water or steam, the frozen material can be thawed in a cold region. Is also available. Further, as shown in the figure, the water supply nozzle 24 is connected to the adjusting device 25 via the water supply line 25a, and for example, depending on the concentration of the waste paste C in the storage tank 26 or the type / state of the garbage-like waste A. The water supply amount of the water supply nozzle 24 can be adjusted by the adjusting device 25. A sensor or the like for detecting the water content (water content) of the waste paste C or garbage-like waste A is attached to the storage tank 26 or the cylindrical body 2, and the water supply amount is automatically adjusted by the adjusting device 25 according to the output of the sensor. It is also possible to do.

  According to the present invention, since the foreign matter separation device and the slurry tank are integrated, the pretreatment consisting of the separation of foreign matters in the garbage-like waste A and the adjustment of the concentration and particle size of the organic matter can be realized by a single device. The installation area required for pretreatment can be greatly reduced. Further, the waste paste C after the foreign matter separation is dropped directly into the storage tank 26, and the paste discharge screw 67a, paste transfer device 68, and transfer line 70 (see FIG. 10) can be omitted. This not only eliminates the possibility of blockage of the transfer line 70 and the like, but also keeps the operation cost low and enables continuous operation at a low pretreatment cost. Furthermore, by supplying water from the water supply nozzle provided on the cylinder, the concentration of the supplied slurry is adjusted and the efficiency of separating foreign materials from garbage-like waste is improved, and high-concentration slurry that does not contain foreign materials can be recycled with minimal dilution. It can be supplied to a resource recycling system and can contribute to efficient recycling by high-concentration slurry.

  Thus, it is possible to achieve the “garbage-like waste supply device that is compact and can be continuously operated”, which is an object of the present invention.

  The supply device 1 shown in FIG. 1 is connected to the cylinder 2 and the storage tank 26 described above, a storage hopper 36 for storing bag-like garbage-like waste, and a bottom of the storage hopper 36, and is connected to the press-fitting device 33. It has an extruding device 37 with a bag-breaking function, and it is possible to take in garbage-like waste A in a bag as it is. For example, it is economical if the extrusion screw 43 at the bottom of the storage hopper 36 shown in FIG. 10 has a bag breaking function, and the drive energy of the extrusion screw 43 can be used for bag breaking of garbage-like waste A. Energy saving can be achieved.

  FIG. 3 shows an enlarged view of a storage hopper 36 provided with an extrusion device 37 with a bag breaking function at the bottom. The illustrated extruding device 37 includes a pair of parallel spiral feed blade 40 rotating shafts 38, 38 extending to the bottom of the hopper 37, and the feed blades 40 are alternately attached to the outer portions of the shafts 38, and A blade 41 with a spiral blade having an outer diameter equal to or less than the outer diameter of the feed blade 40, and a cylindrical outer wall 42 that covers the outer periphery of the feed blade 40 and the blade 41 with both shafts 38 and has an opening 46 at the outer end Have The blade with blade 41 is a spiral blade in which a blade for breaking the bag of garbage-like waste A is formed on the outer periphery. By rotating both rotating shafts 38 with a drive device 39 provided on the opposite side of the opening 46 of both rotating shafts 38, the garbage-like waste A in a bag stored in the hopper 36 is fed to both shafts 38, 38. While quantitatively taking in between the pair of blades 40 and the outer wall 42, the blades 41 are pushed out from the opening 46 while being pressed against the inner surface of the outer wall 42 by the pair of blades 41 with blades.

  An extruding device 37 in the illustrated example has a rotating shaft extension 38b and a cylindrical outer wall extending portion 42b via a connecting portion 45 on the rotating shaft 38a and the cylindrical outer wall 42a of the biaxial extrusion screw 43 at the bottom of the container 1A. An extrusion unit 44 with a bag breaking function is connected, and spiral feed blades 40 and spiral blade-equipped blades 41 are alternately provided on the outer periphery of the rotating shaft extension 38b of the unit 44. The feed blade 40 on the rotation shaft extension 38b is an extension continuous with the feed blade 40 on the rotation shaft main body 38a. The blades 41 with blades are provided in the gap between the feed blades 40 at substantially the same pitch as the feed blades 40, and the outer diameter of the inner side of the hopper 36 is decreased and the outer diameter is gradually increased toward the outer side. desirable. By gradually increasing the outer diameter of the bladed blade 41 toward the outer side of the hopper 36, the bladed blade 41 becomes an obstacle to the smooth conveyance of the garbage A in a bag by the feed blade 40. Can be avoided. The opening 46 has a shape in which the outer end of the cylindrical outer wall extension 42b is cut obliquely with respect to the length direction of the rotating shaft extension 38b (for example, cutting angle θ = about 45 degrees), and the cylindrical outer wall extension It is desirable to form on the lower surface of the outer end of 42b.

  Preferably, as shown in FIG. 3 (B), a protrusion having a V-shaped cross section, for example, projecting toward the space at a portion of the inner surface of the cylindrical outer wall extending portion 42b facing the space between the rotating shafts 38b. 47a and 47b are provided. In accordance with the rotation of both rotary shafts 38, the baggable garbage A can be pressed against the ridges 47a and 47b together with the outer wall 42, and the blades 41 with blades can be efficiently broken even in the space between the rotary shafts 38. It becomes. More preferably, as shown in FIG. 2C, the inner surface of the cylindrical outer wall 42 facing the blade 41 with blades and / or the ridges 47a, 47b is formed by, for example, a linear blade in the length direction of the rotary shaft 38. A fixed blade 48 is attached. The periphery of the fixed blade mounting portion 49 has a slight outward bulge, and contact between the feed blade 40, blade with blade 41 and the fixed blade 48 can be avoided. By the fixed blade 48 in the direction intersecting with the blade with blade 41, more efficient bag breaking of the garbage A in a bag-like waste can be expected.

  Collecting garbage-like waste A in a bag in the storage hopper 36 as shown in FIG. 1 and pushing out the garbage-like waste A in the hopper 36 using an extrusion device 37 with a bag-breaking function, and at the same time reliably breaking the bag, By quantitatively introducing the opening 46 of the extrusion device 37 into the intake port 16 of the cylindrical body 2 through the press-fitting device 33, the quantitative supply bag breaker 14 (see FIG. 10), which has been indispensable for conventional pretreatment, Omitted, a compact pre-processing system having a small vertical height compared to a conventional gravity pre-processing system can be realized. Further, it is not necessary to arrange the storage hopper 36, the cylinder 2 and the storage tank 26 in the direction of gravity, so that the pretreatment system can be freely arranged and designed.

  FIG. 4 shows an embodiment of a pretreatment system using the supply device 1 of the present invention. For example, baggage business waste A discharged from a large-scale commercial facility is collected in a storage hopper 36 by a truck 63, and continuously put into the cylinder 2 through an extrusion device 37 with a bag breaking function and a press-fitting device 33. throw into. The foreign matter B that has been separated in the cylindrical body 2 and discharged from the discharge port 18 is collected by the foreign matter hopper 64 and is transported to the foreign matter disposal plant 66 by, for example, the sealed foreign matter transport device 65. Further, the waste paste C after separation of the foreign matter dropped from the cylinder 2 to the storage tank 26 is circulated to the pulverizer 29 while being stirred in the storage tank 26 and pulverized to a required particle size. After being diluted to the required concentration by the feed water, it is conveyed from the supply port 30 to the bioreactor 55 via the slurry pump 54 and the slurry supply line 71. The supply device 1 of FIG. 4 has a small installation area and installation height and is compact, and can continuously pretreat bag-like garbage-like waste A and supply it to the bioreactor 55 as a high-concentration slurry S.
