Description

TECHNICAL FIELD The present invention relates to a device for selecting raw materials such as spices.

Structure of Prior Art and Problems Thereof In the case of raw materials such as spices, for example, in the process of crushing and drying the collected raw materials, foreign materials such as metal pieces and stones are often mixed. Therefore, it is necessary to carefully select and remove foreign substances from the raw materials, and until now, the foreign substances have been manually selected, but the foreign substances must be carefully selected over a large amount of raw materials, which requires time and labor, The task was not easy.

Therefore, the present invention has been made with the object of automatically selecting foreign substances from raw materials such as spices according to the present invention.

The present invention is a device for carefully selecting foreign substances from raw materials such as spices, and a storage tank supported oscillatingly, a raw material inlet and a raw material outlet provided at both ends in the horizontal direction of the storage tank, It consists of a large number of small spheres that have a larger specific gravity than the raw material and a smaller specific gravity than the foreign material, and the storage tank is partitioned between the raw material inlet and the raw material inlet and the raw material inlet side. A partition plate that keeps the upper surface of the prilled layer higher than the upper surface of the prilled layer on the raw material outlet side, and a vibrator that vibrates the storage tank. Move it
The feature is that the foreign matter is allowed to sink into the small spherical layer.

Description of Embodiments Hereinafter, embodiments of the present invention will be described.

1 and 2, this device is used as a raw material for spices and the like.
It is for carefully selecting foreign matters (2) such as metal pieces and stones mixed in (1), and has a storage tank (3), a raw material inlet (4) and a raw material outlet (5). The storage tank (3) has a hollow rectangular shape, and the raw material inlet
The (4) and the raw material outlet (5) are provided at both ends in the horizontal direction of the storage tank (3), and the raw material inlet (4) is arranged at a position higher than the raw material outlet (5).

The storage tank (3) is vibratably supported. In this embodiment, the brackets (6) project from the four corners of the storage tank (3), and the support rods (7) penetrate through the holes (6a) formed in the brackets (6) as shown in FIG. And the upper end of the support rod (7) is the ceiling of the room
It is fixed to (8). Then, below the bracket (6), the flange nut (9) is screwed onto the support rod (7), and the flange nut (9) and the support rod (7) are fixed by the double nut (10). A spring (11) is provided between the (6) and the flange nut (9), and the spring (1
The storage tank (3) is supported by 1). Furthermore, on the upper side of the bracket (6), the flange collar (8) is
It is fitted to (7) and the flange collar (8) and support rod (7) are fixed by push screw (12), and bracket (6)
A spring (13) is provided between the flange collar (8) and the flange collar (8), and the storage tank (3) is held by the spring (13). Therefore, the storage tank (3) can be vibrated vertically. With the vibration of the storage tank (3), the spring (1
1) and (13) expand and contract in the vertical direction and elastically deform. The diameter of the hole (6a) of the bracket (6) is larger than the diameter of the support rod (7). Therefore, the storage tank (3) can also vibrate horizontally.

With the horizontal vibration, the springs (11) and (13) are inclined horizontally and elastically deformed.

Furthermore, this device has two types of vibrators (14) and (15). The vibrator (14) has a fan-shaped cast iron unbalancer (16), which is fixed to the vertical shaft (18) and
It is attached to the bottom of (3) and is connected to the motor (22) via pulleys (19), (20) and belt (21), and the motor (22) is supported on the bottom of the storage tank (1). . On the other hand, the vibrator (15) has a built-in weight and a motor, is attached to the bottom of the storage tank (3), and the weight is rotatably supported around a horizontal axis perpendicular to the paper surface and is motor-connected. .

Furthermore, a globule layer composed of a large number of globules (23) is housed in the storage tank (3). The small spheres (23) are made of ceramic and have the same size, and their specific gravity is larger than that of the raw material (1) and smaller than the foreign matter (2) such as metal pieces or stones mixed with the raw material (1).

The storage tank (3) has four chambers (1
It is divided into a) to (1d). The height of the partition plate (24) gradually decreases from the raw material inlet (4) side toward the raw material outlet (5) side, and the small balls (23) are divided into chambers (1a) to (1d). Board (24)
The upper surface of the small ball (23) on the raw material inlet (4) side is maintained at a position higher than the upper surface of the small ball on the raw material outlet (5) side.

A net (25) is provided in front of the raw material outlet (5), and the size of the net of the net (25) is larger than the small balls (23) and smaller than the raw material (1). Below the net (25) is a small ball exit (26) through which small balls (23) pass.
Is provided under the small ball container (2) for receiving the small ball (23).
7) is located.

A raw material container (28) for receiving the raw material (1) is arranged below the raw material outlet (5).

In the selection device for spices and the like configured as described above,
When the vibrator (14) is operated, the motor (22) rotates, and the vertical shaft (18) and the unbalancer (16) rotate via the pulleys (19), (20) and the belt (21). When the imbalancer (16) rotates, centrifugal force acts on the imbalancer (16), and the storage tank (3) vibrates in the horizontal direction to perform a circular motion. Further, when the vibrator (15) is operated, the weight rotates inside, the centrifugal force acts on the weight, and the storage tank (3) vibrates slightly in the front-back and vertical directions.

Therefore, when the raw material (1) is continuously charged from the raw material inlet (4), the raw material (1) and the small spheres (23) are fluidized by the vibration and microvibration of the storage tank (3), and the raw material (1) is Chamber (1a) of storage tank (3)
From the upper surface of the small sphere layer to the upper surface of the small sphere layer of the chamber (1b), to the upper surfaces of the small sphere layer of the chamber (1c) and the chamber (1d), and continuously moving. At the same time, each chamber (1
In a) to (1d), foreign matter (2) having a specific gravity greater than that of the small ball (23)
Sink to the bottom of the layer of globules (23). The raw material (1) itself is a small ball (2
It has a smaller specific gravity than 3) and does not sink to the microsphere layer. Therefore, in each chamber, the foreign matter (2) is carefully selected from the raw material (1), and the foreign matter (2) sinks to the bottom of the prilled layer. Then, the raw material (1) falls from the chamber (1d) onto the net (25), and the raw material (1)
Goes down through the material outlet (5) and is received by the material container (28). In addition, foreign matter accumulated at the bottom of each chamber
The small balls (23) are extruded by (2), and the small balls (23) are the raw material (1).
May get mixed in.

The globules (23) fall downward through the mesh of the net (25) and the globules outlet (26) and are received by the globules container (27). Therefore, the foreign material (2) can be selected from the raw material (1) and only the raw material (1) can be taken out. Motors for vibrators (14) and (15) are raw materials
Depending on the specific gravity of (1) and foreign matter (2), it is possible to select the rotation speed most suitable for the selection.

EFFECTS OF THE INVENTION As described above, according to the present invention, in raw materials such as spices, foreign substances such as metal pieces and stones can be automatically selected, so that time and labor are reduced and the intended purpose is achieved. Can be achieved.
