Description

  The present invention is, for example, a waste product for washing solids by crushing a waste product containing moisture, such as a packaged beverage with an expiration date or a bag of garbage, and separating it into a fluid and a solid. The present invention relates to a crushing and separating apparatus.

  2. Description of the Related Art In recent years, as the efforts for environmental problems become popular, various technologies for collecting waste such as waste plastic and waste paper and recycling them as useful resources have been developed. In the technology of recycling waste, generally, the collected waste is first crushed into small pieces, and then a process is performed in which dirt and dust attached to the waste are washed and removed.

  In relation to such waste processing technology, Japanese Patent No. 4121510 discloses a cleaning and dehydrating apparatus for cleaning and dewatering waste plastic after being crushed. In this washing and dewatering device, by a plurality of paddles attached to a rotating shaft supported in the casing, an almost constant feed is applied from the inlet port side to the outlet port side with respect to the plastic piece that has been input, Cleaning and dehydration are effectively performed by centrifugal force while preventing the occurrence of non-uniform staying places.

Japanese Patent No. 4121510

  However, the conventional washing and dehydrating apparatus requires a crushing apparatus because it is necessary to crush the waste as a pretreatment, and thus there is a problem that the apparatus configuration necessary for recycling the waste becomes large. Moreover, when the crushing dimension of the waste is relatively large, the thrown-in waste may be entangled with the paddle and the rotation shaft, and the rotation of the paddle may be stopped. Furthermore, there is a possibility that the waste is clogged between the wall surface of the processing space and the paddle, and the rotation of the paddle is hindered.

  Accordingly, an object of the present invention is to provide a waste crushing / separating apparatus that can input waste without pretreatment, and that can crush, separate, and wash waste without entanglement or clogging. It is to provide.

In order to solve the above problems, the waste crushing and separating apparatus of the present invention has a waste input port at one end and a treated waste discharge port at the other end, and is separated from the waste at the bottom. A horizontally long casing having a discharge mechanism for discharging the separated separated product;
A horizontally long rotating shaft rotatably supported in the casing;
A plurality of rotary blades that are attached to the rotary shaft and crush the waste introduced from the inlet,
A plurality of rotary blades attached to the rotary shaft on the discharge port side from the rotary blade, and each of the wastes crushed by the rotary blade with the rotation from the input port side to the discharge port side A rotating blade arranged to be twisted so as to advance;
A porous member disposed on the lower side of the casing and surrounding a part of the rotation path of the rotary blade;
It is a space formed in the upper part in the casing, and is provided with a first marginal space that is adjacent to the passage region of the rotating blades and that can receive the waste being processed.

  According to the above-described configuration, for example, a waste product containing fluid such as a packaged beverage whose expiration date has expired or a bag of raw garbage stored in a solid material is rotated from a charging port at one end of the casing. It is crushed by the blade. Thereby, for example, the packed beverage is crushed and the beverage is released, and the bagged garbage is broken and the garbage is released. The crushed waste is advanced to the discharge port side by rotating rotating blades. At this time, for example, a fluid such as beverage or garbage receives centrifugal force from the rotating rotating blades and is separated through the porous member. The fluid separated through the porous member is discharged from the casing by the discharge mechanism. Solid matter remaining in the casing without passing through the porous member is washed by removing the attached fluid by the centrifugal force from the rotary blade. Further, the solid matter remaining in the casing is dehydrated by the centrifugal force from the rotating blades. Here, dehydration means not only water but also separation of solids such as liquid and earth and sand adhering to the solid material from the solid material together with water. When the moisture adhering to the solid is relatively small, the solid is dried by the air flow generated in the casing by the rotation of the rotary blade. The solid matter that has reached the other end of the casing is discharged from the discharge port. In the casing in which such processing is performed, the first marginal space is provided in the upper portion of the casing, so that the waste is entangled with the rotating shaft and the rotating blades, and the waste is formed between the rotating blades and the inner wall surface of the casing. The inconvenience of clogging in between is prevented.

  Thus, according to the crushing and separating apparatus of the present invention, waste can be separated into fluid and solid while preventing waste from being entangled or clogged, and the solid can be washed and dehydrated. Therefore, for example, wastes that contain moisture such as pack-drinks that have expired or bags that are packed in garbage, beverages and garbage that are fluids, and crushed pieces or bags that are solids It can be separated into pieces stably, and can be further separated in a state where the solid is washed and dehydrated. As a result, it is possible to effectively and efficiently obtain a solid material that can be used as a renewable resource such as, for example, a renewable fuel material.

  Here, in the present invention, the fluid means a fluid that has fluidity and can permeate the pores of the porous member. Is also included. On the other hand, solids have dimensions that do not permeate the pores, and liquids that do not substantially penetrate like plastic, metal, glass, etc., even if liquid penetrates, such as paper, The thing by which the dimension which does not permeate | transmit a porous hole is maintained by maintaining a shape is also contained.

  In one embodiment of the waste crushing and separating apparatus, the rotary blade is separated from the rotary blade at a predetermined interval in the length direction of the rotary shaft, whereby the rotary blade, the rotary blade, A second marginal space is formed between the two.

  According to the above embodiment, by forming the second margin space, waste immediately after crushing or in the middle of crushing passes through the second margin space without being immediately subjected to the action of the rotating blades. It is rotated later. Therefore, for example, even when a relatively large amount of waste is introduced, it is possible to effectively prevent tangling of the waste with respect to the rotating blades and clogging between the rotating blades and the inner wall surface of the casing.

  In the waste crushing / separating apparatus according to an embodiment, the second marginal space has a length of the rotating shaft with respect to the rotating blade, with the plurality of rotating blades being arranged in the circumferential direction of the rotating shaft. It is formed by being spaced apart at a predetermined interval in the vertical direction.

  According to the embodiment, the second marginal space is formed every other circumferential direction of the rotating shaft, so that the waste is entangled with the rotating blades or between the rotating blades and the inner wall surface of the casing. In addition to preventing clogging, waste can be prevented from staying, and sufficient processing efficiency can be ensured.

  In the waste crushing and sorting apparatus according to an embodiment, a plurality of ribs are disposed on the inner wall surface of the casing that defines the first marginal space, and the waste in the first marginal space is associated with the rotation of the rotary blades. It is formed so as to be directed toward the discharge port side.

  According to the embodiment, the casing can be reinforced by the plurality of ribs, and the waste can be advanced to the discharge port side while preventing the occurrence of non-uniform staying portions.

  Hereinafter, a waste crushing and sorting apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a side view schematically showing a waste crushing and separating apparatus 10 and a supply device 40 for supplying a fixed amount of waste to the crushing and separating apparatus. FIG. 2 is a perspective view of the main part of the main body of the crushing and separating apparatus 10. 3 is a schematic plan view showing the inside of the main part of the main body of the crushing and separating apparatus 10, FIG. 4 is a longitudinal sectional view of the main part of the main body of the crushing and separating apparatus 10, and FIG. 10 is a schematic plan view of 10 main body main parts. FIG. 6 is a cross-sectional view taken along line II in FIG. FIG. 7 is a rear view of the crushing and sorting apparatus 10 as viewed from the outlet 3 side.

  The crushing and separating apparatus 10 crushes and cleans a waste material containing a fluid in a solid material and recycles it for recycling. The crushing and separating apparatus 10 has, as its basic structure, a casing 1 having a waste inlet 2 continuously supplied to one end thereof and a treated waste outlet 3 at the other end thereof. is doing. The casing 1 includes a box-shaped lower casing 1a having a substantially pentagonal cross section and a semi-cylindrical upper casing 1b. An input port 2 is formed on the front end face of the upper casing 1b, while a discharge port 3 is formed in a portion near the back surface of the side surface of the upper casing 1b. As shown in FIG. 7, a duct 31 that extends in the tangential direction of the semi-cylinder of the upper casing 1b and is bent downward is connected to the discharge port 3. The upper casing 1b is connected to the upper end of the lower casing 1a by a hinge so as to be openable and closable, and the inside can be exposed during maintenance. The casing 1 is also provided with a screw conveyor 9 at its lower end as a mechanism for discharging separated substances such as fluids and fine solids separated from waste.

  Further, a rotating shaft 20 is rotatably supported by the casing 1, and the waste thrown in during the rotation of the rotating shaft 20 is placed on the peripheral surface of a portion of the rotating shaft 20 inside the casing 1. A plurality of rotating blades 21 that are advanced from the nozzle to the discharge port 3 side are attached. The rotary blade 21 is twisted and disposed on the peripheral surface of the rotary shaft 20. For example, the angle α (see FIG. 5) of the rotary blade 21 with respect to the axis C of the rotary shaft 20 is set to about 15 °. . In addition, angle (alpha) with respect to the axis C of the rotary blade 21 can be set in the range of 3-30 degrees, Preferably, it is 10-20 degrees.

  As shown in FIG. 1, in this embodiment, a biaxial screw arranged in the horizontal direction as a supply device that is installed adjacent to the crushing and separating device 10 and supplies waste to the input port 2. An input screw device 40 having 42 is employed. The loading screw device 40 rotationally drives the biaxial screws 42 and 42 toward the inside of each other as viewed from above, and thereby, the force that pushes the screws 42 and 42 into the casing 1 side into the wastes. Make it work. The screw 42 of the loading screw device 40 is fixed at a predetermined interval to the rotating shaft 42a to which the driving force from the motor is input, the spiral blade 42b fixed to the outer peripheral surface of the rotating shaft 42a, and the outer edge of the spiral blade 42b. The plurality of cutting blades 43 are generally configured. By the charging screw device 40, the waste material charged from the charging port 41 as shown by the arrow A is continuously pushed out to the casing 1 side and supplied in a fixed quantity. At this time, the waste is crushed by the cutting blade 43 in the process of being continuously pushed out by the screw 42 by the charging screw device 40 and is subjected to a prior crushing action. Further, as the two screws 42, 42 rotate, the cutting blade 43 of one screw 42 passes through a position close to the rotating shaft 42a of the other screw 42, so that waste is wound around the other rotating shaft 42a. Inconvenience can be prevented. The waste previously crushed by the biaxial screw 42 of the charging screw device 40 is pushed out into the casing 1 from the loading port 2, and the pushed portion is cut by a rotary blade 24 described later. The input screw device 40 is not limited to the one provided with the two-axis screws 42 arranged in the horizontal direction. For example, the input screw device 40 having only one screw 42 may be supplied in a fixed amount into the casing 1. Any structure can be used. Further, the screw 42 may not have the cutting blade 43.

  Further, a screen 13 as a porous member is disposed on the lower side of the casing 1 so as to surround the lower side of the rotation path of the rotary blade 21. The screen 13 is formed using a semi-cylindrical punching metal, and the diameter of the hole of the punching metal is 3 to 6 mm. Since the diameter of the holes of the screen 13 is 3 to 6 mm, it is possible to suppress the passage of the solid waste while maintaining the cleaning effect. The size of the holes in the screen 13 can be appropriately set according to the size of the waste to be treated, the size of the fluid component to be separated from the waste, and the like. In addition to the punching metal, the porous member may be formed of a wire mesh, a lattice, or a combination thereof. Further, the porous member may be used for the purpose of separating waste other than the purpose of removing the fluid from the waste.

  The fluid separated from the waste passes through the screen 13 and then collects in the lower part of the casing 1. The fluid collected in the lower part of the casing 1 is conveyed by the screw conveyor 9 and discharged from the discharge port 4 as indicated by an arrow B.

  The rotary shaft 20 is supported horizontally by bearings 28 and 29 disposed in front and rear of the casing 1. The rotary shaft 20 is driven to rotate in a clockwise direction when viewed from the front side, that is, the upstream side (right side in FIG. 1) by a motor (not shown) so that the peripheral speed of the rotary blade 21 is 25 to 30 m / sec. Is done. The driving force of the motor is input to the rotary shaft 20 via a pulley (not shown) provided at the end of the rotary shaft 20 that extends from the bearing 29 to the outside of the casing 1.

  In the present embodiment, six rotating blades 21 are attached to the rotating shaft 20 at a pitch of 60 degrees in the circumferential direction of the rotating shaft 20. Moreover, each rotary blade 21 is supported by the bracket 23 so that the working surface that contacts the waste and transmits the centrifugal force is substantially orthogonal to the rotary blade 21. 1 to 5, the illustration of the bracket 23 is omitted. Each rotary blade 21 is provided with a plurality of circular through holes 21a in order to suppress the influence of air resistance that increases as the rotation speed increases, and to promote drying of the separated solid matter. .

  As can be seen from FIG. 6, in the present embodiment, a first margin space S <b> 1 that can receive the waste being processed is formed inside the upper casing 1 b and adjacent to the passage area of the rotary blade 21. Yes. At least a part of the waste is received at the timing when the waste is lifted above the casing 1 in the first margin space S1. That is, the waste can escape to the first marginal space S1. Therefore, the entanglement of the waste with the rotary blade 21 and the clogging of the waste between the rotary blade 21 and the inner wall surface of the casing 1 can be prevented.

  In the present embodiment, the plurality of ribs 11 are formed on the inner wall surface of the casing 1 that defines the first margin space S1. In FIG. 5, the plurality of ribs 11 and the rotary blades 21 at positions (uppermost positions) facing the ribs 11 are indicated by solid lines. Moreover, the projection position in the top view of the discharge port 3 is shown with a dashed-two dotted line. Both the plurality of ribs 11 guide the waste W received in the first marginal space S1 in the direction of the arrow E in accordance with the rotation of the rotary blade 21 (that is, the movement in the direction indicated by the arrow D). It is oriented so as to advance toward the outlet 3 side. That is, the rib 11 is inclined with respect to the radial direction of the rotary shaft 20 of the rotary blade 21 toward the discharge port 3 from the input port 2 toward the rotational direction of the rotary blade 21 in plan view. The inclination angle of the rib 11 with respect to the radial direction of the rotary shaft 20 is set to 15 °. The inclination angle of the rib 11 with respect to the radial direction of the rotating shaft 20 can be set within a range of 3 to 30 °, and preferably 10 to 20 °. In this way, with the configuration in which the rib 11 is formed on the inner wall surface of the casing 1, the waste can be advanced toward the discharge port 3 side while preventing the occurrence of the staying portion of the waste. Further, the rib 11 can reinforce the upper casing 1b to which the rib 11 is fixed.

  Furthermore, in the present embodiment, a plurality of rotary blades 24 for crushing the waste introduced from the inlet 2 on the front side, that is, the upstream side (right side in FIG. 1) of the rotary blades 21 together with the rotary blades 21. The rotary shaft 20 is provided so as to be rotatable. Specifically, three rotary blades 24 are attached to the rotary shaft 20 in the circumferential direction of the rotary shaft 20 at a pitch of 120 degrees. On the other hand, corresponding to these rotary blades 24, as shown in FIG. 6, a fixed blade 5 extending from the inner wall surface of the casing 1 toward the rotary shaft 20 is attached in the vicinity of the insertion port 2. Along with the rotation of the rotary shaft 20, first, the waste pushed into the casing from the input port 2 by the input screw device 40 is cut. Subsequently, when the rotary blade 24 sequentially contacts and separates from the fixed blade 5, the fixed blade 5 and the rotary blade 24 sequentially perform a shearing action to sequentially crush the waste.

  In addition, in the present embodiment, the rotary blade 21 is spaced apart from the rotary blade 24 in the length direction of the rotary shaft 20 by a predetermined interval, so that the rotary blade 21 is interposed between the rotary blade 24 and the rotary blade 21. A second margin space S2 is formed. More specifically, the second marginal space S <b> 2 has a predetermined interval in the length direction of the rotary shaft 20 with respect to the rotary blade 24 every other rotary blade 21 in the circumferential direction of the rotary shaft 20. And spaced apart. That is, in the present embodiment in which a total of six rotating blades 21 are attached to the rotating shaft 21, three second margin spaces S2 are formed corresponding to every other three rotating blades 21 in the circumferential direction. ing.

  According to the configuration in which such second margin space S2 is formed, waste immediately after crushing or in the middle of crushing is guided to the second margin space S2 without being immediately subjected to the action of the rotary blade 21. Thereafter, a rotational force is received from the rotary blade 21. Therefore, for example, even when a relatively large amount of waste is introduced, it is possible to effectively prevent tangling of the waste with respect to the rotary blade 21 and clogging between the rotary blade 21 and the inner wall surface of the casing 1. . In addition, since the second marginal space S2 is alternately formed in the circumferential direction of the rotating shaft 21, it is possible to suppress the stagnation of waste and ensure sufficient processing efficiency.

  Furthermore, in the present embodiment, a rubber-made flexible contact member 22 is attached to each rotary blade 21 at an edge portion facing the inner wall surface of the casing 1. The rotating blade 21 rotates while the flexible contact member 22 is in contact with the inner wall surface of the casing 1 and the inner peripheral surface of the screen 13, so that the rotating blade 21 and the inner wall surface of the casing 1 and the inner periphery of the screen 13 are rotated. The state which contacted between the surfaces is maintained, and waste can be conveyed effectively. In addition, the rotating blade 21 rotates in a state where the flexible contact member 22 is in contact with the inner wall surface of the casing 1, so that waste enters the space between the rotating blade 21 and the inner wall surface of the casing 1 to cause clogging. Can be prevented. In addition, the flexible contact member 22 should just have the flexibility which can slide, contacting the inner wall surface of the casing 1, and may be formed with materials other than rubber | gum.

  Furthermore, in this embodiment, a supply pipe 14 for supplying a cleaning fluid for cleaning waste into the casing 1 is connected to the casing 1. An adjustment valve 15 is interposed in the supply pipe 14, and the opening degree of the adjustment valve 15 is adjusted by a valve driving device (not shown). The supply pipe 14 is connected to the end surface of the casing 1 on the side where the input screw device 40 is provided, and the discharge ports 14a of the supply pipe 14 are open on both sides of the input port 2 as shown in FIG. . Water as a cleaning fluid is supplied to the supply pipe 14, and water having a flow rate adjusted by the adjustment valve 15 is supplied into the casing 1. The waste fluid is washed away from the solid matter by washing fluid supplied from the supply pipe 14 into the casing 1. The cleaning fluid may be hot water of 100 ° C. or lower, saturated steam or superheated steam of 100 ° C. or higher, in addition to water. The saturated steam or superheated steam is preferably injected into the casing 1 at a pressure of 0.1 Mpa or more and 0.2 Mpa. The type and flow rate of the cleaning fluid can be appropriately selected or adjusted according to the type of waste.

  Next, a procedure for processing waste, in which raw garbage as a fluid is contained in a resin bag as a solid, by the crushing and separating apparatus 10 having the above configuration will be described. First, the waste introduced into the input screw device 40 from the input port 41 is sent to the casing 1 side by the screws 42 and 42 and crushed in advance by the cutting blade 43, and pushed out into the casing 1 from the input port 2 of the casing. It is. Waste that is being pushed into the casing 1 from the charging port 2 by the charging screw device 40 is cut by the rotary blade 24 while being partially held by the tip of the screw 42. Further, the extruded waste and the cut waste are crushed by the shearing action of the fixed blade 5 and the rotary blade 24. As a result, the solid bag is broken to discharge the fluid garbage, and the relatively large garbage is crushed. The waste thus crushed passes through the additional second marginal space S2, and is then conveyed by the rotary blade 21.

  During this conveyance, when the crushed waste is rotated at a high speed together with the rotary blade 21 and a large centrifugal force is applied, the fluid garbage is passed through the screen 13 and driven to the lower casing 1a side. Fluid waste is effectively separated from waste. In addition, the fluid attached to the crushed pieces of the solid bag is washed and separated by the cleaning fluid supplied into the casing 1 through the supply pipe 14. Thus, by separating the fluid garbage from the waste, the crushed pieces of the resin bag, which is a solid, are washed. Further, the crushing pieces of the resin bag are effectively dehydrated by the centrifugal force received from the rotary blade 21. Further, when the amount of water contained in the waste is small, the crushed pieces of the resin bag are effectively dried by the air flow generated in the casing 1 by the rotation of the rotary blade 21. In particular, in the present embodiment, since the through-hole 21 a is formed in the rotary blade 21, the crushed pieces of the resin bag pass through the through-hole 21 a of the rotary blade 21 in the casing 1 as the rotary blade 21 rotates. Thereby allowing it to dry effectively in contact with the air stream.

  Further, during the conveyance of the waste by the rotary blade 21, at least a part of the waste is received in the first margin space S <b> 1 at a timing when it is lifted above the casing 1. The waste received in the first marginal space S1 is gradually advanced toward the discharge port 3 by the feeding action received from the rotary blade 21 and the guide action received from the rib 11 as the rotary blade 21 rotates. .

  The garbage, which is a fluid collected at the lower part of the casing 1, is then conveyed by the screw conveyor 9 and discharged out of the casing 1 from the discharge port 4. On the other hand, the crushed pieces of the bag, which are solid matter remaining in the casing 1 without passing through the screen 13, exit from the discharge port 3 through the duct 31 due to the centrifugal force acting on the rotary blades 21, and the arrows in FIG. 7. As indicated by F, the air is discharged out of the casing 1 from the opening 31 a at the tip of the duct 31.

  Thus, according to the crushing and separating apparatus 10 of the present embodiment, the waste obtained by containing the fluid as a solid is effectively crushed, the fluid and the solid are effectively separated, and the fluid is obtained. It is possible to obtain a crushed piece of solid matter that is not adhered and is washed and dehydrated. Further, the first and second marginal spaces S1 and S2 can prevent waste from being entangled with the rotary blades 21 and clogging between the rotary blades 21 and the inner wall surface of the casing 1, and thus the rotation of the rotary blades 21. Stopping can be reliably prevented. Therefore, waste can be crushed and separated with high efficiency to obtain washed solid crushed pieces. Therefore, it is possible to efficiently obtain recycled resources that can be effectively used as a material for regenerated fuel. Moreover, since the crushing and separating apparatus 10 of this embodiment can perform grinding | pulverization, separation, and washing | cleaning with the single apparatus with respect to the waste which accommodates a fluid with a solid substance, before waste, No processing is required, so that the apparatus configuration can be simplified and the processing process can be simplified.

  In the above embodiment, the crushing and separating apparatus 10 processes a resin bag containing garbage as waste, and separates garbage attached to the crushed pieces of the bag by centrifugal force, and crushes the bag. Although the fluid adhering to the piece was washed and separated with the cleaning fluid, the fluid may be separated only by the centrifugal force of the rotary blade 21 without supplying the cleaning fluid. Further, when the solid matter has oil stains, water containing a detergent may be supplied into the casing 1 through the supply pipe 14 as a cleaning fluid. Moreover, in order to strengthen not only the dehydration by the centrifugal force of a rotary body but the drying effect by a wind, the air blower which sends a wind in the casing 1 may be added.

  Moreover, in the said embodiment, although the crushing and separating apparatus 10 processed the garbage and the resin-made bag as a waste, the waste in which the drink as a fluid is accommodated in the paper pack and metal can as a solid Alternatively, a waste product in which edible oil as a fluid is contained in a plastic bottle or metal can as a solid may be treated. Moreover, you may process the resin waste to which earth and sand and compost adhered like the used agricultural resin sheet. In this case, the crushing and separating apparatus 10 can obtain a crushed piece of a resin sheet obtained by effectively separating and washing earth and sand and compost. Moreover, you may process the resin waste to which organic substance adhered like the used food packaging material and packaging material. In this case, the crushing and separating apparatus 10 effectively separates and cleans odorous waste such as meat and seafood packaging materials and packaging materials, and removes odors. Clean resin fragments can be obtained.

  As described above, according to the crushing and separating apparatus of the present invention, a waste material in which a liquid, a gel-like material, a fluid formed of a minute solid or an organic material, and a solid material such as paper, plastic, metal, or glass is mixed. To obtain a clean solid from which the fluid has been removed.
