Description

[Detailed Description of the Invention] This invention relates to an annular vibrating conveyor whose entire purpose is to easily convey materials such as powder that are relatively easy to adhere to.

Conventionally, various methods are known for discharging all the powder or granules (hereinafter referred to as powder, etc.) generated by drying in a spray dryer, fluidized granulation dryer, etc., but powders with poor fluidity, etc. Or in case of highly adhesive powder etc.

It is difficult to discharge the powder easily, and there are problems in that powder and the like accumulate near the discharge port of the dryer or the like.

Furthermore, because the dryers and the like do not have flat bottoms due to their structure, they have the disadvantage of being difficult to operate because the buttons click when cleaning the inside.

However, the annular vibrating conveyor of this invention is provided with a cross-sectional annular conveying member that is airtightly connected to the lower part of the spray dryer whose lower part is formed in an annular shape through a bellows valve. is provided with a conveyance/discharge port, a plywood board is suspended from the annular conveyance member so as to vibrate freely, and a vibration device is installed on the plywood board.

The suspension device is: A weight is connected to a shaft fixed to the lower side of the annular conveying member, an arm is fixed to the side of the shaft, and a guide member for the weight is fully connected to a spring provided at the tip of the arm. The lower end of the guide member is fixed to the plywood.

Further, the vibration excitation device is constructed by attaching all unbalanced weights to a rotating shaft installed on a plywood board.

When the shaft of the vibrating device is rotated as described above, the plywood is vibrated by the action of the unbalanced weight, and this vibration is transmitted to the annular conveying member via the suspension device.

Here, since the hanging device supports the annular conveying member below the bottom plate, circumferential vibration occurs in the annular conveying device.
Powder and the like within the annular conveyance member flow in a predetermined direction.

As a result, the powder and the like are sequentially discharged from the discharge hole formed in the lower wall of the conveying member.

That is, to explain this invention with reference to an embodiment, an annular conveying member 4 having a cross-sectional shape is connected to a lower end discharge port 2 of a processing tank 1 of a spray dryer through a bellows 3.
A plywood board 6 is suspended so that it can vibrate freely through the suspension devices 5, 5 under the bottom of the board, and an unbalanced weight 7.7 is placed on the plywood board 6.
A driven wheel 9.9 is rotatably mounted and fixed to the shafts 8, 8 of the unbalanced weight 7.7, and a vibration device drive shaft 10.
V-belt 12 is attached to drive wheels 11, 11 fixed to both ends of the
12', and a V-belt 16 is hung between one drive wheel 11 provided on the vibrating device drive shaft 10 and the drive wheel 15 provided on the electric motor 14 installed on the base plate 6. This constitutes a vibration excitation device for the conveying member 4.

In the figure, 17 is a hot air pipe, 18 is a spray nozzle, and 19 is an exhaust pipe.

As shown in FIG. 3, the suspension device 5 has a weight 24 connected to a shaft 23 fixed to the lower side of the annular conveying member 4, and an arm 25 completely fixed to the shaft 23. The base plate 6 is completely suspended from a spring 26.26 provided at the tip of the base plate 6 via a guide member 27.27 of the weight 24.

According to the annular vibrating conveyor having the above configuration, the raw material such as powdered milk sprayed from the soufflé nozzle 18 descends in the processing tank 1 of the spray dryer and is introduced from the hot air pipe 17.
It is dried by the hot air discharged into the exhaust pipe 19 and falls into powder into the annular conveying member 4 .

On the other hand, the unbalanced weight 7.7 to which the full rotational force is applied by driving the electric motor 14 is given an advance angle of a predetermined angle, so that the base plate 6 is vibrated, and the vibration is transmitted from the suspension devices 5, 5. It is transmitted to the annular conveying member 4.

Since the suspension device supports the lower side of the bottom plate of the annular conveying member 4, the annular conveying member 4 vibrates in the circumferential direction.

The powder that has fallen onto the annular conveying member 4 is placed under vibration, and the powder is conveyed in the direction shown by the solid line arrow 20 in FIG.

Therefore, the powder on the annular conveyance member 4 is sequentially conveyed and reaches the discharge hole 21 formed in the lower wall of the annular conveyance member 40.
1 and is discharged through a chute 22 connected to the lower side thereof.

Note that the method of imparting vibration to the annular conveyance member 4 is not limited to the above embodiment, and various methods such as a balanced type, a resonance type, a moderation type, etc. can be adopted.

In addition, since the annular conveying member 4 has a U-shaped entire cross section, workability is good when cleaning the inside of the processing tank 1 of the dryer, etc.
It also has the effect of making maintenance and inspection easier.

That is, according to this invention, the entire base plate is suspended from the bottom of the cross-sectional annular conveying member via a hanging device, and the vibrating device is installed on the base plate to form the entire annular vibrating conveyor. , the powder discharged from the processing tank of a spray dryer, etc. can be efficiently transported and sequentially discharged from the discharge port provided at the bottom of the annular conveying member, and maintenance and inspection of the dryer, etc. can be facilitated. It has the effect of

Since the shredded processing tank and the annular transport member are connected by the bellows, they are transported one after another without coming into contact with the outside air.

In addition, the vibration is fully controlled by the vibrating device, the spring and the weight, which has the effect of making the discharge more efficient.
