Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an apparatus for sorting feathers, and more particularly, to a feather fiber removing apparatus for separating down and fibers and removing the feather fibers.

[Prior art] Raw wool, which is the raw material for feathers, is a mixture of various sizes of feathers and debris, such as king feathers, small feathers, down, and fibers that have fallen off from down feathers. In order to be able to use the feathers as a product, it is necessary to further sort the feathers by size after completing each process such as dust removal, washing, drying, and cooling.

And even if you sort down to the smallest size down,
Note that the down contains fibers and the like from which some of the down has fallen.

And if the fiber content in the down is high,
For example, when used as batting for bedding, there are problems in that the fiber may blow out from the side fabric of the bedding, and that the quality of the bedding cannot be maintained because fiber does not have sufficient elasticity.

On the other hand, extracting fiber from down and increasing the down rate is difficult because both are minute.
This is extremely difficult due to its light weight.

This invention was made to solve the above problems.

[Means for Solving the Problems] The feather fiber removing device according to this invention includes an outer shell, an exhaust means for creating a negative pressure in the outer shell, and a cylindrical rotating body provided in the outer shell. and a backwash pipe arranged around the rotating body to blow air to the rotating body, and a blowing pipe provided inside the rotating body and having a common axis with the rotating body, The shell is provided with an input port for introducing the feathers to be sorted into the rotary body and an outlet for taking out the sorted feathers, and a plurality of fibers corresponding to the size of the fibers to be sorted are provided on the cylindrical peripheral wall of the rotary body. An air hole is provided on the surface of the backwash pipe to blow out the air blown from the blower, and an air hole is provided on the surface of the blower pipe to blow out the air blown from the blower to the outside of the blower pipe. A plurality of air holes are formed to blow out the air, and stirring blades are provided to stir the feathers in the circumferential direction, and the rotating body and the blowing pipe are configured to be rotatable independently of each other.

[Function] Since air is blown inside the rotor by a blowing pipe and stirred by a stirring blade, the down and fibers are easily separated, and the convection of the air inside the rotor causes the feathers to hit the inner surface of the circumferential wall of the rotor, further separating them. become more susceptible to

Furthermore, by creating a negative pressure inside the outer shell to reduce air resistance, etc., it becomes easier to separate the light down and fibers.

In addition, the fibers can be separated and removed by passing through the ventilation holes provided in the peripheral wall of the rotating body according to the size of the fibers, and the fibers clogged in the ventilation holes can be removed with a backwash pipe, making the separation and removal work easier. unimpeded.

In addition, since the blower pipe and rotating body can rotate independently, the rotation speed can be adjusted according to the amount of feathers, etc., and optimal efficiency can be obtained by adjusting the blower volume and speed. .

The fiber container 7 is connected to a fiber storage container 7 for storing fibers and other debris sucked in by the fibers.

Next, a method of using the feather fiber removing device 101 according to the above embodiment will be explained.

First, before driving the feather fiber removing device 101, feathers are prepared in the weighing silo 2, and the amount to be fed into the feather fiber removing device 101, for example, is prepared.
Set up 10Kg and a weighing device.

Therefore, when turning on the rotating body
03 and the blower pipe 106 to drive the stirring blade 111, and the exhaust device 4 sucks air through the pipe 101a to create a vacuum inside the outer shell 102.

By creating a vacuum inside the outer shell 102 in this way, the amount of feathers set in the weighing device in the weighing silo 2 passes through the inlet 117 and is sucked into the rotating body 103. be accommodated.

Note that when 10 kg of feathers are input, the ratio of the feathers to the volume of the rotating body 103 in the above embodiment, that is, the bath ratio, is about 50%.

Next, during the fiber separation/removal operation, the rotating body 103 and the blower pipe 106 are rotated to drive the stirring blades 111, and the blower pipe 10
6 and backwash pipe 112. In this case, the inside of the outer shell 102 is evacuated by driving the exhaust device 6, and the inside of the outer shell 102 is 20mm
Ensure that the negative pressure state of Aq is maintained.

In addition, the air blown from the backwash pipe 106 maintains the passing speed of the rotating body 103 in the air hole 110 at 3 m/s, and the air blown from the backwash pipe 112 maintains the speed at which it reaches the surface of the rotating body 103 at 60 m/s. s.

In this case, the diameter φ of the air hole 109 of the inner tube 106a
is formed so that it gradually becomes smaller as it goes from both ends of the blower pipe 106 to the center.
Air is blown from both ends of the inner tube 106a, and the air is blown into the air hole 10.
The speed of the air blown from the inner pipe 9 into the air blowing chamber 106c is substantially constant at any part of the inner pipe 106a. Moreover, since the air holes 106 and 110 of the inner tube 106a and the outer tube 106b are arranged so as not to face each other, the introduced air is mixed in the ventilation chamber 106c and the pressure is uniform in the ventilation chamber 106c. be converted into As a result, the speed and pressure of the air blown out from the air holes 110 of the outer tube 106b are approximately the same everywhere.

As described above, the outer pipe 10 of the blower pipe 106 is
The air blown out from 6b hits the inner surface of the peripheral wall 104 of the rotating body 103 substantially perpendicularly, as shown in FIG. In this case, a portion of the air that hits the inner surface of the peripheral wall 104 flows along the inner surface of the peripheral wall 104, and further flows toward the blow pipe 106, that is, toward the center, and convection (arrow) occurs.

As a result, the convection currents collide with each other within the rotating body 103, causing turbulence.

The feathers carried by the turbulence are transported to the rotating body 10
The down and fibers are easily separated by being struck against the inner surface of the peripheral wall 104 of No. 3 many times. Moreover,
Since the inside of the outer shell 102 is maintained in a negative pressure state,
Air resistance becomes extremely small, and the down and fibers become more easily separated.

On the other hand, a part of the air that has hit the inner surface of the peripheral wall 104 of the rotating body 103 passes through the ventilation holes 105 in the peripheral wall 104 . In this case, the fibers separated from the down are provided with ventilation holes 1 that are adjusted to the size of the fibers.
05 and is blown out to the outside of the rotating body 103, the down is
Since it is larger, it remains in the rotating body 103 and rotates within the rotating body 103 many times, and further separation and removal work is performed to separate the down and fibers.

Further, during the above-mentioned separation and removal work, the exhaust device 6 is driven to constantly exhaust air into the outer shell 102, and the separated fibers are always sucked and stored in the fiber storage device 7. . In this case, the pressure regulating valve 118
2 is maintained at a constant negative pressure state.

In this way, the fibers are separated from the down, while the ventilation holes 105 of the rotating body 103
The separation effect at the ventilation hole 105 tends to decrease as the fibers fill up, but the air blown from the backwash pipe 112 causes the ventilation hole 1
Fibers near 05 are blown away. As a result, the ventilation holes 105 are not clogged, and the work of separating and removing down and fibers is carried out with constant efficiency.

The feathers are stirred under the above conditions for about 10 to 15 minutes to separate and remove the fibers from the down.

Next, after the work of separating and removing the down and fibers as described above is completed, the down is discharged and recovered.

First, the air blowing from the blower pipe 106 and the backwash pipe 112 and the exhaust device 6 are stopped, and the rotating body 10 is
3 and the blower pipe 106 while the stirring blade 111 is rotated.

On the other hand, the air intake port 119 of the outer shell 102 is opened, the exhaust device 4 is driven, and the down collection container 5 is
suction of air. By this operation, the rotating body 103
The down from which the fibers have been removed is sucked from the down outlet 120 and collected into the down collection container 5.

In the manner described above, down with an extremely high down rate can be extracted from down containing fibers, dust, etc.

[Example] Next, an experimental example using a reduced size of the feather fiber removing apparatus according to the above example will be shown.
A rotating body with a diameter D1 of 50 cm and a length L3 of 90 cm was used.

(Conditions) Feather 28.4%, Fiber 11.5%, Garbage 1.0%,
150g of raw feathers with a mixture with a down rate of 59.1%
was used, and the treatment time was 15 minutes.

The setting conditions are the ventilation pipe passage speed of 3.0.
~3.2m/s, the speed at which the backwash pipe reaches the rotating body
75 m/s, the rotation speed of the blow pipe is 9 rpm, and the rotation speed of the rotating body is 18 rpm.

(Results) Feather 27.88%, Fiber 4.49%, Garbage 0.90
%, and a down rate of 66.73% was obtained, and the down rate was significantly improved, and the fiber and mixing rate were significantly reduced. Good results were also obtained with a yield of 87.3%.

In addition, all of the raw material supply, down, fiber, etc. recovery and storage processes in the feather fiber removal apparatus in the above embodiment can be automatically controlled, and
The air volume, air blowing speed, etc. can also be varied.

Also, the diameter, number and pitch of the ventilation hole 105 of the blower pipe 103 and the air hole 115 of the backwash pipe 112, the width and number of the slits 116, the amount of air blown from the blower pipe and the backwash pipe, the speed of air flow, etc., and the rotating body and the blower pipe. The rotation speed of can be selected depending on the correlation with the amount of raw materials, processing time, etc.

Further, the size of the outer shell 102, the diameter and length of the rotating body 103, the diameters and lengths of the blower pipe 106 and the backwash pipe, etc. are not limited to those of the embodiment.

[Effects of the invention] As explained above, the feather fiber removal device according to the invention separates and removes the fibers within the rotating body that has ventilation holes that match the size of the fibers, so only the fibers can be discharged outside the rotating body. I can do it.

In addition, the air is blown through the air pipe and the feathers are applied to the inner surface of the circumferential wall of the rotating body, and the stirring blades are used to stir the down and fibers, making it easier to separate the down and fibers. Moreover, by creating a negative pressure state inside the outer shell, the separation process is further facilitated. It can be done efficiently and easily.

Furthermore, since a backwash pipe is provided for blowing air onto the rotating body, fibers attached to the ventilation holes of the rotating body can be efficiently removed, and the work of separating and removing the fibers inside the rotating body can be carried out smoothly.

In addition, since the rotating body and the blower pipe can rotate independently, the rotation speed can be set to an efficient speed according to the amount of raw materials and processing time, and the air flow rate, speed, and By adjusting the diameter and porosity of the ventilation holes and air holes,
This has effects such as being able to select efficient conditions.
