Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a suction type wind sorter, and more specifically, for example, classifying the size of chirimenjiyako, small shrimp, and hijiki, removing impurities, etc. , relates to a suction type wind sorting machine for use in various sorting processes.

[Conventional technology]

The chirimenjiyako, small shrimp, etc. mentioned above are generally spread out on bamboo mats and dried in the sun, so hair, straw, dirt, etc. get mixed in during that time or when they are transported, and these must be removed as well. It is necessary to classify the grains according to size and prepare the grains of the product.

Conventionally, in order to classify and remove impurities from the chirimenjiyako and small shrimp mentioned above, the materials to be sorted were placed in a sieve and vibrated, and the waste was removed through the sieve and workers manually separated the materials into sizes. It is.

The conventional method of vibrating a sieve to remove impurities and manually sorting chirimenji, koji, shrimp, etc. is mostly manual work, requires a large number of workers, and is time-consuming. inefficient;
Further, since impurities such as hair get entangled in the sieve and cannot be removed from the sieve, there is a problem in that it takes time and effort to remove them.

Therefore, in order to solve these problems, the present inventor proposed a suction-type wind sorting machine that automatically wind-sorts the objects to be sorted, and filed a patent application.

That is, the sorting chamber is provided with an input port for inputting the materials to be sorted and an air intake port, a conveying vibration generation mechanism for vibrating the entire sorting chamber is provided, and at least one air intake port is provided in the input port of the sorting chamber. We established a wind selection department,
The wind sorting section is provided with a pedestal facing below the input port, the terminal end of the pedestal facing the vertical flow path, and the upper end of the vertical flow path communicating with the separation chamber via a partition wall. At the same time, an air suction port faces the separation chamber, and
This is a suction type wind sorting machine, in which an inclined chute for taking out the first sorted material is arranged below the air suction port, and an outlet for taking out the second sorted material is provided below the vertical flow path. .

[Problem that the invention attempts to solve]

The above-mentioned suction type wind sorter made it possible to mechanize the conventional manual work, but in the wind sorting section,
The end of the pedestal was simply placed facing the vertical flow path, and the falling objects to be sorted were subjected to airflow from below for wind separation.

In this case, the objects to be sorted move from the end of the pedestal to the partition wall, solidify, and fall, making it impossible to produce an effective wind separation effect, resulting in poor wind separation efficiency, which needs improvement. It was wanted.

[Means for solving problems]

Therefore, the suction type wind sorter according to the present invention is
In order to solve the above-mentioned problem of wind sorting efficiency, an input port 2 for inputting the material to be sorted 1 and an air intake port 3 are provided in the sorting chamber A, and vibrations for conveyance are generated to vibrate the entire sorting chamber A. A mechanism 4 is provided, at least one wind selection section B1 is provided in series with the input port 2 of the sorting chamber A, and a cradle 5 is provided in the wind selection section B1 facing below the input port 2. , the terminal end of the pedestal 5 faces the vertical flow path 13, the upper end of the vertical flow path 13 communicates with the separation chamber D1 via the partition wall 6, and the air suction port 7 faces the separation chamber D1, Further, an inclined chute 8 for taking out the first sorted material 1a is provided below the air suction port 7, and an outlet 9 for taking out the second sorted material 1b is provided below the vertical flow path 13. In the suction type wind sorter, the vertical flow path 1
3 is provided substantially vertically, a side wall 13a extending substantially vertically downward from the terminal end of the pedestal 5, and a side wall 13a extending substantially vertically downward from the terminal end of the pedestal 5, and an upper end 6a of the partition wall 6 bypassed from near the terminal end of the pedestal 5. and the outer wall portion A1 forming the separation chamber D1, and is substantially parallel to the outer wall portion A1 and the partition wall 6 and has a lower end portion 3 thereof.
1a is positioned directly above the terminal end of the pedestal 5 with a gap therebetween, and a guide wall 31 is provided.

[Effect]

When items to be sorted, such as chirimenjiyako, are put into the input port, the entire sorting chamber is vibrated by the vibration generating mechanism for transportation, so the object is placed on a tray facing below the input port. is transferred toward one end thereof, and reaches a longitudinal channel facing the terminal end of this cradle. In this vertical flow path, air flows straight upward from below to above, and air flows from the lower end of the guide wall, passes over the end of the pedestal, and passes between the outer wall part and this guide wall. is formed, and this latter flow intersects with the objects to be sorted falling from the end of the pedestal and is reliably forced to pass through the group of objects to be sorted, thereby enhancing the wind selection effect. .

This prevents the objects to be sorted that have fallen from the terminal end of the pedestal from coming to the partition wall, solidifying, and falling.

Such an improvement in the wind selection effect can be achieved by a simple improvement of simply adding a guide wall with a substantially simple structure.

Therefore, hair, straw waste, and chirimenjiyako of a predetermined size are reliably screened, ride the two air currents, bypass the upper partition wall, and reach the separation chamber, where the air currents are slowed down and compared. As the heavy chirimenjiyako falls downward, light hair and straw waste are separated and discharged from the air suction port facing the separation chamber, and the fallen chirimenjiyako are collected from the inclined chute. It is.

[First Embodiment] As shown in FIGS. 1 to 3, the suction type wind sorter of this embodiment has an input port 2 for inputting the material to be sorted 1, for example, chirimenjiyako, and an air intake. An entrance 3 is provided in the sorting chamber A, and a conveying vibration generating mechanism 4 for vibrating the entire sorting chamber A is provided. The fuselage is constructed of steel plates fastened together by appropriate main fastening stages. Although a vibration motor is used here as the conveyance vibration generating mechanism 4, other known means, such as vibration generating means using an eccentric cam, etc. can be used.

A first wind sorting section B1 is provided at the input port 2 of the sorting chamber A.

A first holder 5 for receiving the object 1 to be sorted is provided facing downwardly. The object to be sorted 1 on the first pedestal 5 is conveyed to one end side of the pedestal 5 by the conveyance vibration generating mechanism 4 . This first
One end of the pedestal 5 faces the first vertical flow path 13, and the upper end of the first vertical flow path 13 is communicated with the first separation chamber D1 via the partition wall 6. That is,
the partition wall 6 in which the first vertical flow path 13 is provided substantially vertically;
In response to this, a side wall 13a extending vertically substantially downward from the end of the first pedestal 5 and a side wall 13a extending vertically from the end of the first pedestal 5 bypass the upper end 6a of the partition wall 6 from near the end of the first pedestal 5 to open the separation chamber D1. and the outer wall portion A1 to form a guide wall, and is substantially parallel to the outer wall portion A1 and the partition wall 6, and has its lower end portion 31a located directly above the terminal end of the first pedestal 5 with a gap therebetween. There are 31. In the first vertical flow path 13, air flows straight upward from the bottom to the top, passes from the bottom end of the guide wall over the terminal end of the pedestal, and passes between the outer wall portion and this guide wall. This latter flow intersects with the objects to be sorted falling from the end of the pedestal and is forced to pass through the group of objects to be sorted. Heavy stones and relatively large chirimenji yako fall downward, and relatively small chirimenji yako and lighter objects such as dirt, dust, and hair are lifted up for wind selection. In the first separation chamber D1, a first
The air suction port 7 is exposed, and an inclined chute 8 for taking out the first sorted material 1a is connected below the first air suction port 7, and a second chute 8 is provided below the first vertical flow path 13. Output port 9 for taking out the sorted material 1b
has been established.

The first air suction port 7 is connected to a suction blower 11 via a duct 10.
is driven and controlled by an electric motor 12. This first air suction port 7 is provided with a negative pressure regulating valve 10A in the duct 10 so as to generate a relatively small negative pressure due to the primary sorting. As a result, the negative pressure in the first separation chamber D1 is adjusted, and the material to be sorted after air selection reaches this point.
is separated into extremely light dirt, dust, hair, etc., and relatively heavy small dust particles. Therefore, very light dirt, dust, hair, etc. are discharged from the duct 10 to the outside of the machine via the suction blower 11. The inclined chute 8
is configured in the shape of a duct, and receives the first sorted material 1a, that is, relatively small chirimenjiyako, which has fallen under reduced pressure in the first separation chamber D1. From this inclined chute 8, the conveying vibration generating mechanism 4
The first sorted material 1a is taken out of the machine by the vibration of the machine.

A second wind selection section B2 is connected to the first wind selection section B1. It may be understood that the second wind selection section B2 has substantially the same configuration as the first wind selection section B1, and only differs in the strength of wind selection. This second wind selection part B2
is provided with a second pedestal 14 provided below the outlet 9 for taking out the second sorted material 1b, with one end of the second pedestal 14 facing the second vertical flow path 15,
The upper end of the second vertical flow path 15 is connected to the second vertical channel through the partition wall 16.
It communicates with the separation chamber D2. This second separation chamber D
2 facing the second air suction port 17, and
An inclined chute 18 is provided below the air suction port 17 for taking out the third sorted material 1c, that is, chirimenjiyako of a relatively large class.
Below the vertical channel 15, there is provided an outlet 19 for taking out the fourth sorted material 1d, that is, larger chirimenjiko, impurities such as shrimp or pebbles. The second air suction port 17 is connected to the suction blower so as to generate a relatively larger negative pressure than the first air suction port 7, that is, to make the suction force stronger, in order to perform the second sorting. A duct 20 connected to 11 via a branch path is equipped with a negative pressure regulating valve 20A. As a result, the first air suction port 7
Large pieces of straw that cannot be sucked out can be discharged from the machine.

Further, a third wind selection section B3 is connected to the second wind selection section B2. This third wind selection part B3 also performs the same wind selection function as the first and second wind selection parts B1 and B2,
Here, a third pedestal 21 is provided below the outlet 19 for taking out the fourth sorted material 1d, and one end of the third pedestal 21 faces the third vertical flow path 22,
The upper end of the third vertical flow path 22 is connected to the third vertical channel through the partition wall 23.
It communicates with the separation chamber D3. This third separation chamber D
3 facing the third air suction port 24, and
An inclined chute 25 is provided below the air suction port 24 for taking out the fifth sorted material 1e, that is, large-sized chirimenji and other materials. A take-out port 26 is provided below the third vertical flow path 22 for taking out the sixth sorted object 1f, that is, heavy pebbles, and the suction force of the third air suction port 24 is applied to the first air suction port 7. The duct 27 is equipped with a negative pressure regulating valve 27A and connected to another suction blower 28 so that the suction force is stronger than the suction force of the second air suction port 17. This allows the relatively light impurities that were sucked out and leaked from the previous suction to be almost completely discharged to the outside of the machine. This suction blower 28 is driven by another electric motor 29.

The reason why the upper end 31b of the guide wall 31 described above is curved slightly beyond the upper end 6a of the partition wall 6 is because
This is to ensure the direction of the airflow to the first separation chamber D1.

The lower end 31a of the guide wall 31 is located at approximately the same level as the lower end A2 of the outer wall portion A1 in order to intersect the object 1 with the steepest slope possible.As a result of the experiment, The wind selection effect was increased compared to when the lower end 31a of the guide wall 31 was positioned relatively upward.

Furthermore, the upper end 6a of the partition wall 6 is bent diagonally downward to make it easier for the rising airflow to spread rapidly in the first separation chamber D1, thereby slowing it down.
This is to form a so-called cone nozzle for efficiently reducing pressure.

The configurations corresponding to the first vertical flow path 13 of the first wind selection section B1 and related structures in the second wind selection section B2 and the third wind selection section B3 are completely the same. The description and drawing numbers have been omitted.

[Second Embodiment] FIG. 4 schematically shows a suction type wind sorter having substantially the same structure as the first embodiment, and here,
It is configured to perform first and second sorting.

Therefore, members that are substantially the same as those in the first embodiment are given the same numbers, detailed explanations thereof are omitted, and new member numbers are given to different configurations.
Give a detailed explanation.

As shown in FIG. 4, the lower end of the outer wall portion A1 forming the first vertical flow path 13 is slightly extended below the lower end 31a of the guide wall 31,
It is bent in the opposite direction to the first vertical flow path 13 so that air flow from below can be smoothly guided between the partition wall 6 and this outer wall portion A1.

Further, in order to guide the air from the air intake 3 of the sorting room A over the entire surface, a guide wall 30 is provided, and a first holder 5 is positioned above the guide wall 30, and this first holder 5 is connected to a crimp net. Here, the object to be sorted 1 is conveyed while reversing its vibration using the vibration of the conveying vibration generating mechanism 4, and air is first air-selected by suction air from below, and the object to be sorted is mixed with the object to be sorted. It makes it easier to loosen straw waste and hair, and small pebbles.
It is configured so that it is dropped downward through a crimp net and taken out of the machine.

Then, the airflow that has passed through the first cradle 5 of the crimp net is also guided to the first vertical flow path 13, thereby increasing the amount of air at the terminal end of the first cradle 5, thereby increasing the wind selection efficiency. We are planning to improve this.

Note that punch panels 7A and 17A are provided at the entrances of the first air suction port 7 and the second air suction port 17, respectively, and the small holes of these punch panels 7A and 17A are arranged over the entire surface. , rectify the flow of the suction air so that air is evenly sucked from the entire surface of the suction port, and separate the first separation chamber D1 and the second separation chamber D2.
The structure is designed to prevent the airflow from being biased in the chambers, thereby increasing the separation efficiency within these chambers.

Other aspects such as wind selection are the same as in the first embodiment.

[Effect of idea]

According to the present invention, when the material to be sorted, for example, chirimenji, is air-sorted, a straight upward air flow from the bottom to the top in the vertical flow path;
By forming an air flow from the lower end of the guide wall over the terminal end of the cradle and between the outer wall part and this guide wall, and by forming this latter flow, this air flow By intersecting with the objects to be sorted falling from the end of the filter, it was possible to forcibly pass through the group of objects to be sorted, thereby increasing the wind sorting effect. This prevents objects to be sorted that have fallen from the end of the pedestal from getting closer to the partition wall, hardening, and falling, and hair, straw waste, and chirimenjiyako of a predetermined size are reliably screened. Riding on the two air currents, it bypasses the upper partition wall and reaches the separation chamber, where the air current is decelerated and the relatively heavy chirimenjiyako falls downward, while light hair and straw waste are removed from the separation chamber. The fallen chirimenjiyako is separated and discharged from the air suction port facing the chamber, and is collected from the inclined chute.

Moreover, such an improvement in the wind selection effect can be achieved by a simple improvement of simply adding a guide wall with a substantially simple structure.
