DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind separator which sorts crushed or pulverized waste such as general waste or industrial waste into heavy and light materials.

[0002]

2. Description of the Related Art Conventionally, as this kind of wind sorter, for example, a wind sorter described in Japanese Patent Application Laid-Open No. 5-285454 is known. This wind separator is provided on a lower surface of the casing, a tubular casing installed at an angle, a bar screen arranged in the casing in accordance with the inclination, vibration applying means for applying vibration to the bar screen,
An air outlet for blowing air from below the bar screen to the object to be processed, and a light-weight outlet provided on the upper surface of the casing for discharging the light-weight material separated by the air blowing are provided. In this wind separator, the object to be processed introduced from the upper end opening of the casing is separated by the vibration by the vibration applying means when moving on the bar screen, and is separated into a heavy object and a light object, and the light object is separated. The object is discharged from the light-weight outlet with the air flow from the air jet port, while the heavy object is discharged from the lower end opening of the casing, and the object to be processed is efficiently separated into a heavy object and a light object. That is.

[0003]

However, in the conventional wind sorter, the bar screen is vibrated to unravel the object to be processed, so that it is necessary to take soundproofing and vibrationproofing measures in consideration of the environment. Further, since the processing amount of the processing object is limited by the moving speed of the processing object falling on the bar screen by its own weight, there is a problem that a large amount of space is required to cope with the increase in the processing amount. This tendency is
In particular, it becomes remarkable when the ratio of the light-weight objects in the object to be processed is large. Therefore, the present invention does not require soundproofing and anti-vibration measures,
It is another object of the present invention to provide a wind separator capable of greatly increasing a processing amount without increasing a space. or,
It is another object of the present invention to provide a wind separator capable of further sizing heavy materials separated for the above purpose.

[0004]

In order to solve the above-mentioned problems, a first wind sorter of the present invention is provided with a tubular casing installed horizontally or inclined at a required angle, and provided at one end of the casing. An air inlet for injecting high-speed air into the casing in the longitudinal direction thereof; and an inlet provided on the upper surface of the casing on the downstream side of the air inlet, and through which the workpiece is sucked into the casing by the air flow. When,
An air suction port is provided on the upper surface of the casing downstream of the input port and sucks air at a required speed.The air suction port is provided on the lower surface of the casing so as to face the air suction port. It is characterized by comprising an air blowing port for blowing in, and a discharging port provided at the other end of the casing and discharging the object to be processed. The second wind sorter is the first one, wherein one end is supported by a horizontal pivot at a lower end of the casing and is swingably provided in the casing, and the movement of the object to be processed is brought to just before the air suction port. A guide plate for guiding, the other end of the guide plate is provided continuously so as to cover the air blowing port,
And a bar screen for sieving heavy objects in the object to be processed. Further, the third wind separator is the first or second wind separator, wherein the suction port is connected to the air suction port via a cyclone, and the discharge port is connected to the air pushing port and the air blowing port via a flow control damper. It is characterized by having a blower connected to the mouth.

The angle of inclination of the casing ranges from 0 to 60.
° is preferred. If it exceeds 60 °, it becomes difficult to suck a lightweight object from the air suction port. A more preferable inclination angle is 0.
４５45 °. The speed (wind speed) of the air flow pushed from the air inlet is preferably 4 to 12 m / s. 4m / s
If it is less than 10 m / s, the inertial force at the time of moving the object to be processed by the pushing air becomes weak, and if it exceeds 12 m / s, the effect of the above-mentioned inertial force is so great that it becomes difficult to suck the above-mentioned lightweight object. A more preferred wind speed is 6 to 10 m / s. The speed (wind speed) of the air flow sucked from the air suction port is 9 to 16 m / s
Is preferred. If it is less than 9 m / s, the above-mentioned suction effect becomes weak, and if it exceeds 16 m / s, the suction effect is great, and a heavy object in the processing object is also sucked. A more preferred wind speed is 10 to 15 m / s. The speed (wind speed) of the air flow blown from the air inlet is 3 to 16 m
/ S is preferred. When the speed is less than 3 m / s, a part of the light-weight material in the processed material falls and mixes with the heavy material, thereby lowering the sorting accuracy. When the speed exceeds 16 m / s, the distance between the air suction port and the air blowing port is reduced. The air flowing through the air forms a wall of the air flow against the flow of the forced air, and obstructs the flow of the forced air. A more preferred wind speed is 3 to 10 m / s. The swing angle of the guide plate (an angle parallel to the casing is 0 ° and a downward direction is positive) is preferably 0 to 10 °. If it exceeds 10 °,
The aforementioned suction effect is weak. A more preferable swing angle is 0 to 5 °. It is preferable that the screen under product dropped from the bar screen is collected from the air blowing port. In this case, it is desirable to attach a duct, which is a passage for the blown air and the screen-under product, to the casing at a right angle, or to branch connect a blow duct, which is a passage for only the blown air, to the duct at an angle of 90 ° or less. If the blow duct is branched and connected at an angle exceeding 90 °, blow air may blow out from the discharge port of the screen under product. The preferred branch angle of the blow duct is
30 to 60 °. In addition, the screen under product may be collected by connecting a separating plate to an end of the bar screen so as to vertically separate the inside of the casing and the inside of the discharge port. On the other hand, it is preferable that a straightening plate for equalizing the velocity of the pushing air passing in a cross section perpendicular to the longitudinal direction of the casing is provided in the air pushing port.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view showing an example of an embodiment of a wind separator according to the present invention. In the figure, reference numeral 1 denotes a casing having a tubular shape having a rectangular cross section. The casing 1 is installed horizontally or inclined at a required angle (for example, 30 °) by a support frame 3 erected on a base stand 2. At one end (left end in FIG. 1) of the casing 1, an air inlet 4 for pushing high-speed air (for example, a wind speed of 16 m / s) into the casing 1 in the longitudinal direction is provided. Inlet 4
The discharge port 5 a of the blower 5 is connected to a discharge duct 7 provided with a flow control damper 6. As shown in FIGS. 2 and 3, the inside of the casing 1 is provided inside the air inlet 4 in order to prevent the velocity of the air from decreasing at the corners in the casing 1 and the flow velocity distribution from becoming uneven. A rectifying plate 8 for equalizing the velocity of the pushing air passing in a section perpendicular to its longitudinal direction is provided. On the upper surface of the casing 1 on the downstream side (the right side in FIG. 1) of the air inlet 4,
A hopper 9 serving as an inlet for the workpiece M is provided. The hopper 9 functions as an ejector in which the workpiece M is sucked into the casing 1 by a high-speed air flow from the air inlet 4.

On the other hand, an air suction port 10 for sucking air at a required speed (for example, 15 m / s) is provided on the upper surface of the casing 1 downstream of the hopper 9, and the air suction port 10 is provided with a blower. 5 suction port 5b and cyclone 11

An air blowing port 13 for blowing air toward the air suction port 10 at a required speed (for example, m / s) is provided. The air inlet 13 is provided with a metal such as iron or aluminum in the workpiece M which falls from the other end (the right end in FIG. 1) of the guide plate 15 and a non-metal such as glass fragments or pebbles. net to prevent from entering heavy M _W is a mixture of metal (not shown) is stretched. The air blowing port 13 is connected to the pushing duct 7 via a blowing duct 14 branched immediately downstream of the flow rate adjusting damper 6. As shown in FIGS. 1 and 4, a guide plate 15 for guiding the movement of the processing object to a position just before the air suction port 10 is provided in the casing 1 so as to cover the gap between the processing object and the upper surface of the casing 1. One end (the left end in FIG. 1) is supported by a horizontal pivot 16 at the lower end of the inside of the casing 1 so as to be adjusted in accordance with the properties of the processing object M and the like, and can be swung within a required range (for example, swinging). The angle (the angle parallel to the casing is 0 °, and the downward direction is positive) is 10 °. (In FIG. 1 the right end) and the other end portion of the casing 1, the discharge port 17 is provided for mainly discharging the heavy M _W in the processing object M.

In the wind separator having the above-described structure, the workpiece M supplied to the hopper 9 is sucked into the casing 1 by the high-speed air pushed in from the air inlet 4 and is dispersed (released). The air suction port 10 is guided by the guide plate 15 at a speed higher than the falling speed due to its own weight.
After a fall from a mobile to the guide plate 15 until the front, with is then further dispersed by the air blown from the air blowing port 13, light product M _L therein blown up into the air suction port 10 direction, and the air suction ports 10 The air is separated along with the suction air sucked by the air, and is collected via the suction duct 12 to the cyclone 11. Adjustment of lightweight material M _L sucked by the suction air (adjustment or sucking up those weighing how much of the workpiece in) is pushed wind speed (push air volume), blow wind speed (blowing air volume), suction This is achieved by adjusting the wind speed (amount of suction air) and the distance between the guide plate and the air suction port (the inclination angle of the guide plate). On the other hand, heavy M _W in the workpieces M
Has an inertia in the flow direction due to the action of the pushing air, and is discharged from the outlet 17 overcoming the blowing action of the blown air and the suction action of the suction air.

In the wind separator having the above structure, the object to be processed M is moved at a speed higher than the falling speed by its own weight while being dispersed by the high-speed pushing air.
Because the corresponding further lightweight material M _L after being dispersed by blowing air at the location is separated by suction air and, soundproof as in the prior art with no anti-vibration necessary measures, without increasing the space processing The amount can be greatly increased, and the sorting accuracy can be improved by effectively dispersing the processing object M. The air inlet 4, the air inlet 13 and the air suction port 10 are connected to the discharge port 5 of the blower 5.
Since a closed loop is connected to the suction port 5a and the suction port 5b, air used for processing can be effectively used.

FIG. 5 is a view taken along the line VI-VI in FIG. 3 is an enlarged view of a main part of FIG. The wind sorter, without stretched a net air blowing port 13, the guide plate on the other end of the 15, bar screen 18 an air blowing port 13 for sieving heavy M _W in the workpieces M the while continuously provided so as to cover the collection of screen under article M _W1 dropped from the bar screen 18 for performing the air blowing port 13, the under-products duct 19 serving as a passage for blow air and the screen under article M _W1 A blow duct 14 which is attached to the casing 1 at a right angle and is a passage for only blown air is branched and connected to the under product duct 19 at an angle θ of 90 ° or less. Other configurations are the same as those of the above-described embodiment, and thus the same components and the like are denoted by the same reference numerals and description thereof is omitted.

[0011] In the wind sorter having the above configuration, in addition to the same effects as those of the embodiment described above can be obtained, since the heavy M _W is sieved, it screens under GOODS M _W1 and the screen over it can be sized into two goods M _W2. Here, the discharge of the screen under product _MW1 is not limited to the discharge from the air blowing port 13 through the under product duct 19, but a net is stretched over the air blowing port 13 and the inside of the casing 1 and the inside of the discharge port 17 are formed. _May be connected to the end of the bar screen 18 to separate the screen-under product _MW1 and the screen-over product _MW2 so that the screen under product _MW1 and the screen over product _MW2 are separated from each other.

In each of the above embodiments, the case where the casing is installed at an angle has been described. However, the present invention is not limited to this case. The shape is not limited to a square,
It may be circular or other shapes. Further, the swingable guide plate may not be provided when the property of the object to be processed is constant. Further, the flow regulating plate may not be provided when the flow velocity distribution of the pushing air passing through the cross section perpendicular to the longitudinal direction in the casing becomes substantially uniform.

[0013]

As described above, according to the first wind separator of the present invention, the object to be processed is moved at a speed higher than the falling speed due to its own weight while being dispersed by the high-speed forced air, and the air suction is performed. Lightweight objects are separated by suction air after being further dispersed by the blowing air at the position corresponding to the mouth, so there is no need to take soundproofing and vibration-proofing measures as in the past, and the processing volume is not increased without increasing the space. Can be greatly increased, and the sorting accuracy can be improved by effectively dispersing the objects to be treated. According to the second wind separator, in addition to the function and effect of the first device, the distance between the flow path of the object and the air suction port is variable, so that the suction strength is adjusted according to the properties of the object. Can be easily adjusted, and since a heavy object is sieved, it can be divided into two sizes: a screen-under product and a screen-over product. Further, according to the third wind separator, in addition to the effects of the first or second one, a closed loop in which an air inlet, an air inlet, and an air suction port are connected to a discharge port and a suction port of a blower is provided. With the configuration, the air used for the processing can be effectively used.
