Description

The present invention relates to a vibratory feeder that fluidizes a granular material in a fluid chamber by vibration and moves the granular material from a supply port toward a discharge port. The granular material is heated and dried during the transfer. Or it is a vibration feeder which can be cooled.

As shown in FIG. 7, the conventional vibration fluid drying / cooling device 51 is vibrated obliquely upward by a vibration motor (not shown), and the granular material supplied to one end in the fluid chamber 51a is obliquely upward with vibration. It is transferred to the other end while jumping. At that time, hot air or cold air is blown from the blower 52 into the flow chamber 51a. As a result, hot air or cold air hits the jumped up powder and the powder is dried or cooled.

The hot air supplied to these fluid chambers 51a is discharged from the exhaust port 53 provided at the top of the vibration fluidized drying / cooling device 51 through the tube (not shown) to the dust collector 54, and from the dust collector 54 to the outside through the wind fan 55. Exhausted. On the other hand, the dried granular material is discharged from the other end of the vibration fluidized drying / cooling device 51.

FIG. 8 is a schematic longitudinal sectional view of the vibration fluidized drying / cooling device 51. As shown in the drawing, the vibration fluidized drying / cooling device 51 is supported by a plurality of leg bodies 56 each having a stretchable spring body. Further, the vibration motors (not shown) provided on both sides vibrate obliquely upward in FIG.

A blower chamber 57 to which the hot air is supplied is provided below the flow chamber 51a, and the flow chamber 51a and the blower chamber 57 are communicated with each other through a perforated plate 58. As a result, hot air or cold air is blown from the blower chamber 57 to the flow chamber 51 a through the numerous small holes of the vibration rectifying plate 58. Therefore, the granular material in the fluid chamber 51a is transferred in a predetermined direction on the perforated plate 58 while jumping with the vibration and the wind pressure of hot air or cold air from below, and is dried or cooled.

And the said hot air or cold air is collected by the said dust collector 54 through the pipe line from the said exhaust port 53 provided above the flow chamber 51a. The exhaust air collected in the dust collector 54 is mixed with fine powder in the granular material, collected in the dust collector 54 and discarded. These configurations are the same as the dry cooling apparatus shown in FIG. 2 of Patent Document 1 and the basic configuration of Patent Document 2.

As shown in FIG. 5 (A), the conventional Patent Documents 1 and 2 and the illustrated or other vibration fluidized drying / cooling devices all have the powder fluid P jumped obliquely upward on the transport surface 5a. In this method, the transfer speed of the powder is large to some extent, and it is difficult to transfer at a low speed. It was.

Moreover, in order to make the granular material P jump up on the transport surface 5a, when the transport surface 5a is heated or cooled, it is not always in contact with the transport surface on which the granular material P is heated or cooled, The efficiency of heat exchange was poor.

In addition, in the above-mentioned Patent Documents 1 and 2, or the method of blowing hot air or cold air such as the vibration fluidized drying / cooling device shown in the figure, if the granular material is expensive such as pharmaceuticals and foods, As described above, when the fine powder in the granular material is collected in the dust collector and discarded, the yield of the processed product at the time of the drying or cooling treatment is poor, leading to an increase in cost.

Further, since the exhaust air is collected in the dust collector 58 from the exhaust port 57 of the vibration fluidized drying / cooling device 52 through the pipe line, equipment such as a pipe line and a dust collector is required, and the equipment cost and the running cost are required. .

Therefore, the present invention solves the above technical problem, and the particles are moved obliquely upward by the vibration that pushes up obliquely upward with respect to the transport surface of the conventional particles, thereby transporting the particles. Instead of a method of transferring from one end of the surface to the other end, a vibratory feeder that can transfer the granular material from one end of the transport surface to the other without jumping up from the transport surface, thereby reducing the transfer distance per unit time It is to provide. Further, it is an object to provide a heating / cooling vibration feeder with good heat exchange efficiency by heating or cooling the transport surface with the above-described configuration, and allowing the granular material to be dried or cooled during transport.

According to the first aspect of the present invention, in the vibratory feeder provided with a substantially cross-sectional channel-type flow frame that vibrates and transfers from one to the other with powder particles inside, the transport that forms the lower surface of the flow frame The surface is inclined so as to have a downward slope, and a vibration source that provides vibration in a direction substantially parallel to the transport surface is provided. Two vibration sources are arranged side by side along the upper end outer surface of the flow frame. The vibration feeder was provided with a rotation axis of each vibration motor perpendicular to the transport surface .

According to a second aspect of the present invention, both ends of the flow frame are closed with walls, a lid is provided at an upper opening of the flow frame to form a sealed flow chamber body, and the inclined transport surface The vibration feeder according to claim 1, wherein the lid located on the front side is provided with a supply port for powder and a discharge port is provided at a front end side end of the transport surface.

Moreover, invention of Claim 3 was set as the vibration feeder of Claim 2 provided with the heating source or cooling source which heats or cools the said transport surface.

According to a fourth aspect of the present invention, there is provided the vibration feeder according to the third aspect, wherein a window is opened in the lid of the fluid chamber main body, and the window is covered with a filter.

According to the first aspect of the present invention, since the transport surface of the granular material vibrates substantially parallel to the transport surface, it does not jump up from the transport surface as in the prior art and moves back and forth along the transport surface. However, because of the downward slope, the granular material moves by its own weight along the slope of the transport surface. In this way, the granular material moves from one end of the transport surface to the other end.

Therefore, if the angle of the downward slope of the transport surface is reduced, the transfer speed of the granular material is reduced. This can be transferred at a speed of 1/2 or less as compared with the conventional method in which the transport surface is vibrated in an oblique direction and the granular material is moved while being pushed up obliquely. Further, in the conventional method in which the granular material jumps up obliquely from the transport surface, the granular material soars in the flow frame, but in this respect, in this invention, the granular material does not jump from the transport surface, The recovery rate is extremely high.

According to the second aspect of the present invention, since the fluid chamber is substantially sealed and the granular material does not fly up from the transport surface during transfer, it does not scatter from the fluid chamber. Furthermore, there is no possibility that foreign matter is mixed in from the outside during the transfer of the granular material.

Further, according to the invention of claim 3, since the heating source or the cooling source for heating or cooling the transport surface is provided, the granular material does not always move away from the transport surface as described above, and moves back and forth. Since it is repeatedly transferred in the inclined direction, it is transferred while always in contact with the heated or cooled transport surface. Therefore, the heat exchange efficiency is very good as compared with the conventional method in which the granular material is transferred from the heated or cooled transport surface while being transported and dried or cooled.

Moreover, in this invention, unlike the conventional method of applying hot air or cold air to the granular material,
Since the powder particles are heat-exchanged on the heated or cooled transport surface, the fine particles in the powder particles are not discharged together with the exhaust air, and are all collected and the yield is good.

Further, according to the invention of claim 4, since a window with a filter is provided at the top plate portion of the fluid chamber, when the powder is dried, the moisture of the powder becomes steam by heat exchange, This steam can be exhausted naturally from the window as an updraft, and heat exchange can be promoted.

The present invention relates to a vibratory feeder provided with a cross-sectional channel type flow frame that moves a powder granule inside and vibrates from one to the other. A transport surface that forms the lower surface of the flow frame is defined as a downward slope. Provided with a vibration source that applies vibration in a direction substantially parallel to the transport surface, closed both ends of the flow frame with walls, and a lid at the upper opening of the flow frame. A closed fluid chamber body is formed, a supply port for powder is provided in the lid located on the front side of the inclined transport surface, and a discharge port is provided at the end on the front end side of the transport surface. Further, the vibration feeder according to claim 1 is provided.

As a result, since the transport surface vibrates substantially parallel to the transport surface, the granular material does not jump up from the transport surface as in the past and moves back and forth along the transport surface, but because the transport surface is a downward slope, The powder particles move by their own weight along the slope of the transport surface. In this way, the granular material is transferred from one end of the transport surface to the other end.
