Description

  The present invention relates to a wind vibration separating apparatus that separates a heavy object and a light object by wind and vibration.

  In order to promote the reduction and recycling of container and packaging waste, which accounts for a large portion of waste discharged from households, as waste increases with mass production and consumption, and adverse environmental impacts become a social issue. In addition, a law (container and packaging recycling law) concerning the separate collection and recycling of containers and packaging has been enacted, and in order to effectively use resources and build a recycling-oriented society with less environmental impact, separate disposal, separate collection, Re-commercialization is being promoted.

  For example, metal, glass bottles, PET bottles, etc., among the waste discharged from the household are reused as raw materials for products. In addition, combustible materials such as waste plastics such as containers and packaging are crushed, dried, and compression-molded among waste materials, and are effectively used as waste solid fuel (RDF).

  In general, it is instructed to sort waste according to the type specified by each municipality, but usually waste discharged from households is often insufficiently separated, and metals, Incombustible materials such as glass are included as foreign matter, and conversely, incombustible materials such as waste plastic such as containers and packaging are included in the incombustible material as foreign matter.

  In order to effectively reuse waste, it is desirable to classify and separate the collected waste so that it does not contain foreign materials that do not meet the purpose, and to take out the intended product alone for reuse. However, it is generally difficult to take out only the target object ideally. To date, various devices such as a wind separation device, a vibration separation device, a separation device using both wind and vibration, and a magnetic separation device for separating magnetic metal have been used for sorting and separating waste. Yes.

  There have been many reports on sorting devices using wind and vibration.

  For example, Patent Document 1 described below entitled “Wind Sorting Device” includes “a wind sorting device that separates light and heavy materials contained in dust crushed from automobiles or home appliances, and serves as a raw material passage. An upper frame having a supply rod, a staircase portion that is attached to the downstream side of the supply rod, has an air blowing port formed at the rear thereof, and has a plurality of treads, and a discharge rod attached to the downstream side of the staircase portion And the upper frame is supported by a coil spring attached in a forward inclined state toward the raw material moving direction and a plate spring attached in a rear inclined state toward the raw material moving direction, and the lower part is supported by the spring. An intermediate frame to which a vibration source is attached and a dust collector connected to the dust collector through a duct. And the piping to the air outlet is performed through a bellows-shaped duct, the step plate of the staircase portion is substantially horizontal, and the raw material is gradually moved downstream by the vibration of the staircase portion. And the tip of the upper tread of the staircase is configured to partially overlap the rear end of the lower tread.

  Patent Document 2 below entitled “Wind Wind Sorting Device” includes “wind force generating means, a plurality of nozzle means for ejecting a plurality of air currents by the wind force generated by the wind force generating means, A plurality of airflow direction adjusting means for directing a plurality of airflows ejected by the nozzle means in a substantially determined direction, respectively, and a plurality of dropping steps discontinuously provided in the direction in which each airflow heads. To provide a sorting channel structure including at least two sorting channels, and to the sorting channel structure, a thrust in a channel direction component parallel to the sorting channel and an orthogonal component orthogonal to the sorting channel. Describes a wind-power sorting device comprising an oscillating means for applying a vibration force to the sorting channel structure in an oblique direction, and the “step for dropping the upper sorting channel is the same as that of the lower sorting channel. For the step for dropping “It is positioned obliquely upward toward the flow side”, “an oblique direction in which the dropping step of the upper sorting channel is positioned relative to the dropping step of the lower sorting channel In the upper direction, it is described that the wind direction of the air flow ejected from the nozzle means is adjusted. "

  Although the structure of the wind power separating apparatus based on the specific gravity sorting method based on the wind pressure of air is relatively simple, the separation is insufficient. Further, in the magnetic separation device, only magnetic metals such as iron, cobalt, and nickel are to be separated, so that the application range is limited. In addition, wind separators, vibration separators, separators that use both wind and vibration, etc., often use a sieve to separate and recover, but there are problems with maintenance due to clogging of the sieve. .

  In addition, in the wind power sorter that separates the lightweight and heavy objects described in Patent Document 1, the tip of the upper tread of the staircase provided with a plurality of treads partially overlaps the rear end of the stock tread. The dust that has fallen from the upper tread due to vibration falls to the lower tread. The heavy objects in the dust are sucked into the mouth, fall down to the bottom tread board, and are further conveyed downward by vibration, and the light and heavy objects are separated from the dust. It is said that some of the heavy objects in the dust are not removed from the staircase at each stepping plate step, so the staircase is used until all of the heavy objects in the dust reach the discharge bin. Exists in the department Therefore, there is a problem that separation of the light material sandwiched these heavy is difficult.

  In addition, the wind power sorting apparatus described in Patent Document 2 has a tilting sorting channel structure for sorting consisting of two stages of upper and lower tilt sorting channels configured in multiple stages, and a step for dropping the upper sorting channel. Is positioned obliquely upward toward the downstream side with respect to the step for dropping of the lower sorting channel, and the step for dropping of the upper sorting channel is positioned with respect to the step for dropping of the lower sorting channel.

As shown in FIG. 1, the apparatus main body, which is the main part of the wind vibration separation apparatus, includes a heavy object (W _h ) and a light object (W _l ) included in an object to be separated introduced from an input chute (input port). ).

  As shown in FIG. 1 (A), the apparatus main body is connected to a heavy load storage section that stores a separated heavy load and has a heavy load outlet via a bellows. In addition, a lightweight object storage unit that stores the separated lightweight object and has a lightweight object outlet is connected to an intermediate connection part that is connected to the apparatus main body part and includes an exhaust duct via a bellows.

The main body of the apparatus has six decks (shelf plates (metal flat plates)) P ₁ , P ₂ , P ₃ , P ₄ , P ₅ , P ₆ , and these decks are stepped downward. Are arranged in a shape. Here, each of the six decks has the same shape and is provided with an air nozzle at the bottom, and the deck surface is horizontally arranged. It goes without saying that the six decks may have different shapes. For example, the length of each of the six decks (that is, the length between the front end portion and the rear end portion of the shelf board) is made different, so that the separation of heavy and light items is made more efficient. You may be able to do that. The shorter the length of each of the six decks, the lighter objects can be blown away and moved from the shelf board with lower pressure air, so that the efficiency of separating heavy and light objects can be increased.

In the following description, the side close to the position of the throwing shoe in the horizontal direction is the rear side, the far side is the front side, the front end of the deck P _n (n = 1 to 6) is the tip, and the rear of the deck P _n The end on the side is called the rear end. That is, the distal end portion of the deck P _n denotes the end of the positive direction in the horizontal direction shown in FIG. 1 (right side), the rear end of the deck P _n, the negative direction of the horizontal direction shown in FIG. 1 (left side) Means the end of

As shown in FIG. 1, when n = 2 to 6, the rear end region of the deck P _(n-1) and the front end region of the deck _Pn are arranged so as to overlap in the vertical direction. In the example shown in FIG. 1, each of the six decks has the same length in the horizontal direction, and each of a line connecting the leading end of each deck and a line connecting the rear end of each deck. And the angle formed by the horizontal positive direction is about −30 °.

As shown in FIG. 1B, six air nozzles are arranged at the lower part of each deck P _n (n = 1 to 6). As shown in the enlarged view in FIG. The central axis of the nozzle is oblique to the deck _Pn surface, and the tip of each air nozzle is located in the lower part near the rear end of the deck _Pn , and the air is directed from the front to the rear end. Are discharged and flow to the exhaust duct.

The air pressure discharged from each of the six air nozzles arranged at the bottom of each deck _Pn may be the same or different, and is changed according to the position of the arranged air nozzles. Also good. As shown in FIG. 1 (B), an air adjustment valve is provided in the air flow path connected to each of the six air nozzles arranged at the bottom of each deck _Pn . The released air pressure can be adjusted.

The apparatus main body is held by four elastic bodies (support springs), and FIG. 1 shows three support springs D ₁ , D ₂ , and D ₃ . A vibration force from the vibration means is applied to the device main body, and the vibration force causes the device main body to form a vibration direction (this vibration direction (X direction) and a horizontal positive direction shown in FIG. The angle is −45 °). The six decks also vibrate in the vibration direction by the vibration force.

  FIG. 1 shows an example in which an unbalanced weight mechanism using a centrifugal force generated by rotation of an unbalanced weight is used as the vibration means.

  This unbalanced weight mechanism has the same mass and shape, and the first and second unbalanced weights having the same rotation center position and the same center of gravity position as vibration bodies (the centrifugal force generated by the rotation of the unbalanced weights). The first unbalanced weight is fixed to the rotating shaft A, the second unbalanced weight is fixed to the rotating shaft B, and the first unbalanced weight and the second unbalanced weight are The unbalanced weight is configured to rotate in the opposite direction at the same speed.

  The rotation of the first unbalanced weight around the rotation axis A generated by the motor (motor) held on the motor support is transmitted to the rotation axis B by, for example, a gear, and the second unbalanced weight is transmitted. The weight rotates at the same speed around the rotation axis B in the direction opposite to the rotation direction of the first unbalanced weight. This unbalanced weight mechanism does not require a complicated mechanism and is easy to maintain. In the example shown in FIG. 1, the angle formed between the line connecting the rotation axis A and the rotation axis B and the horizontal positive direction is 45 °.

When the vibration force generated by the unbalanced weight mechanism is applied to the apparatus main body, the six decks P ₁ , P ₂ , P ₃ , P ₄ , P ₅ , and P ₆ are shown in FIG. Vibrates in the vibration direction. Be separated containing the heavy and light matter is, when it is turned from the input chute, firstly, it is caught by the receiving plate air nozzle in the lower part is located, and then falls down to the deck P _1.

During this time, the light released from the air nozzle disposed at the lower part of the receiving plate blows off and moves the lightweight object (W _l ) in the object to be separated to the right in FIG. 1, and the decks P ₁ , P ₂ , P ₃ , P ₄ , P ₅ , P ₆ , the lighter is blown to the right in FIG. It falls to the storage.

The heavy object (W _h ) in the separated object on the deck P ₁ receives the force that vibrates in the vibration direction shown in FIG. 1 and moves to the left while vibrating on the deck P _{1. 1} Drops from the upper left end (rear end) to the heavy load storage unit.

On deck P ₂ directly is caught by the receiving plate, the isolate was dropped, the isolate dropped by the vibration of the deck P _1, which is further discharged from the air nozzle disposed in the lower portion of the deck P ₁ There may be a lightweight object that is blown away by the air and moved. Heavy receives a force that vibrates in the vibration direction as shown in FIG. 1, continue to move in the left direction while oscillating on deck P _2, heavy storage portion from the left end of the deck P ₂ (the rear end) It falls down to.

Further, light that is present on the deck P ₂ are deck P _1, by the air emitted from the air nozzle disposed in the lower portion of the deck P _2, light was gradually moved blown to the right in FIG. 1 Furthermore, the light objects are blown to the right in FIG. 1 by the air discharged from the air nozzles arranged at the lower parts of the decks P ₃ , P ₄ , P ₅ , and P ₆ , so that they are lighter. It falls to the object storage part.

In this way, heavy and lightweight objects are separated by the air discharged from the air nozzles disposed at the bottom of each deck and the vibrations of the objects to be separated on the decks P ₁ and P ₂ . In the same manner, the air to be separated from the air discharged from the air nozzles arranged at the lower part of each deck and the decks P ₃ , P ₄ , P ₅ , and P ₆ are sequentially subjected to vibration. , Heavy and light weight will be separated.

FIG. 2 is a diagram for explaining the separation of the heavy object (W _h ) and the light object (W _l ) and the angle of the deck by the wind vibration separation device according to the embodiment of the present invention.

FIG. 2A is a diagram illustrating separation of a heavy object (W _h ) and a light object (W _l ), and FIG. 2B is a diagram illustrating an angle of the deck with respect to the horizontal direction.

Focusing on one deck, as described above, on this deck, the separation object dropped by the vibration of the rear deck, and the air discharged from the air nozzle arranged at the lower part of the rear deck. There may be lightweight objects that have been blown away and moved. The heavy object (W _h ) receives a component F parallel to the deck surface of the force that vibrates in the vibration direction shown in FIG. 2 (A), and moves to the left while vibrating on the target deck. It falls from the (rear end) to the heavy load storage unit.

In addition, the lightweight object (W _l ) present on the noted deck is the right object of FIG. 2A by the air released from the air nozzle disposed at the lower part of the noted deck and the rear deck. The lightweight object is blown and moved to the right in FIG. 2 (A) by the air discharged from the air nozzles disposed at the lower portions of the front decks. Then, it falls to the lightweight object storage part.

  1 and 2A, the case where the deck surface is parallel to the horizontal direction has been described as an example. However, as shown in FIG. 2B, when about 15 °> θ> 0 °, a) When the deck surface forms an angle of (−θ) with the positive direction in the horizontal direction, and (b) When the deck surface forms an angle with the positive direction of the horizontal direction and (+ θ), the vibration direction of the deck is When the vibration direction is the same as that shown in FIG. 2 (A), the object to be separated on the deck receives the force in the left direction of FIG. 2 (B). It moves to the left while vibrating, and falls from the left end (rear end) to the heavy load storage unit. A lighter object is more likely to fall from the left end (rear end portion) of the deck than in the configuration shown in FIG. 2B, particularly in the configuration shown in FIG. 2B, compared to the configuration shown in FIG.

  In the above description regarding FIG. 1 and FIG. 2, the angle formed by the vibration direction and the horizontal positive direction is −45 °, but this angle may be + 45 °, and it is possible to separate heavy and light objects. It is. When this angle is + 45 °, the deck surface is parallel to the horizontal direction as shown in FIGS. 1 and 2A, and the deck surface is set to the horizontal positive direction as shown in FIG. In any case where the angle is (± θ), the vibration direction of the deck is a direction orthogonal to the vibration direction shown in FIG. 2A, so that the object to be separated on the deck receives a rightward force. Therefore, it moves rightward while vibrating on the deck, and falls from the right end (tip portion) to the heavy load storage unit.

  The angle formed between the vibration direction and the horizontal positive direction is not limited to -45 °. The angle between the line connecting the rotation axis A and the rotation axis B and the positive direction in the horizontal direction, the vector connecting the center of gravity G of the first unbalanced weight and the rotation center A, and the second unbalance weight By adjusting the relative relationship between the vector connecting the center of gravity G and the rotation center B, the angle between the vibration direction and the horizontal positive direction is set to an arbitrary angle α satisfying −90 ° <α <0 °. Can do.

  Next, the vibration force and vibration direction generated by the unbalanced weight mechanism as described above will be described.

  FIG. 3 is a diagram illustrating a vibration force generated by a centrifugal force generated by a pair of unbalanced weights of the wind vibration separating apparatus according to the embodiment of the present invention.

  The left figure shown in FIG. 3 (A) shows a pair of unbalanced weights in which the center of gravity of each of the pair of unbalanced weights is disposed in the same direction from the straight line connecting the rotation center A and the rotation center B. FIG. 3 is a diagram showing a state in which the weights are rotated in opposite directions, and the right diagram in FIG. 3A is a diagram showing a state after time t when each of the pair of unbalanced weights is rotated.

  FIG. 3B is a diagram illustrating a state in which each of the pair of unbalanced weights is rotated 180 ° from the state illustrated in the left diagram of FIG.

  FIG. 3C is a diagram illustrating the direction of the vibration force generated by the centrifugal force generated by the rotation of the pair of unbalanced weights.

  3A shows the arrangement of the first and second unbalanced weights of the vibrating body shown in FIG. 1, and the center of gravity G of the first and second unbalanced weights indicates the rotation center A. And a vector connecting the center of gravity G of the first unbalanced weight and the center of rotation A, and the center of gravity G of the second unbalanced weight, A state in which the vectors connecting the rotation centers B are parallel is shown.

  When the first and second unbalanced weights rotate in the opposite directions around the rotation centers A and B, respectively, and the state shown in the left diagram of FIG. As shown in the figure, the angle formed by the resultant force of centrifugal force generated by the rotation of the balance weight and the horizontal positive direction is −45 °, and the resultant force acts only in the positive direction of the X direction. Yes.

The right diagram in FIG. 3A shows a rotation state after time t from the state in the left diagram in FIG. 3A, the X-direction component of the centrifugal force f ₁ generated at the center of gravity G of the first unbalanced weight is f _1X = f ₁ cos (ωt) (ω is an angular frequency). ), The Y-direction component is f _1Y = −f ₁ sin (ωt). The X direction component of the centrifugal force f ₂ generated at the center of gravity G of the second unbalanced weight is f _2X = f ₂ cos (ωt), and the Y direction component is f _2Y = f ₂ sin (ωt). is there. Since f ₁ = f ₂ (= f), the resultant force in the X direction is f _X = f _1X + f _2X = 2fcos (ωt), and the resultant force in the Y direction is f _Y = f _1Y + f _2Y = 0. Therefore, as in the case of the right diagram in FIG. 3A, the resultant force due to the rotation of the first and second unbalanced weights acts only in the positive direction of the X direction.

  Further, in the state shown in FIG. 3B rotated 180 ° from the state shown in the left diagram of FIG. 3A, the resultant force due to the rotation of the first and second unbalanced weights is only in the negative direction of the X direction. It is acting on.

  Therefore, the resultant force due to the rotation of the first and second unbalanced weights vibrates in the positive and negative directions in the X direction, and the vibration direction is in the X direction as shown in FIG.

  Note that FIG. 3 illustrates the case where the angle formed by the vibration direction and the positive direction in the horizontal direction is −45 °, but as described above, the line connecting the rotation axis A and the rotation axis B and the horizontal direction And the relative relationship between the vector connecting the center of gravity G of the first unbalanced weight and the center of rotation A and the vector connecting the center of gravity G of the second unbalanced weight and the center of rotation B. By adjusting the angle, the angle formed by the vibration direction and the horizontal positive direction can be set to an arbitrary angle α satisfying −90 ° <α <0 °. That is, the vibration direction can be set in an arbitrary direction with respect to the horizontal direction.

  In the above description, the number of decks is six, the number of air nozzles arranged at the bottom of each deck is six, and the angle between the line connecting the ends of each deck and the horizontal positive direction is about −30.
