Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder vibration device for filtering, separating, pulverizing, mixing, etc. powder and granule materials.

To explain the embodiment according to the drawings, a fixed board 3 is horizontally supported by two pillars 2, 2 vertically established at intervals on a floor fixed board 1, and a lower part is provided in the center of the fixed board. The electric motor 5 is fixedly installed with the rotating shaft 4 protruding in the direction. Reference numeral 6 denotes a hanging rod that is inserted perpendicularly into the peripheral edge of the fixed board 3, and is compressed between the double nut T screwed onto the upper end and the upper surface of the fixed board 3.

A coil spring 8 is interposed, and a coil spring 10 is also interposed between the pot member 9 fixed to the approximate middle part of the hanging rod and the lower surface of the fixed board 3, so that each hanging rod can be moved up and down and can be swung slightly from side to side. Install freely. 11 is fixed to the lower end of the hanging rod 6 with a nut 12.

The diaphragm is a closed horizontal diaphragm, and a vibration generator 13 housed in a casing is provided in the center of the diaphragm. That is, inside the casing, a rotating shaft 16 is vertically supported by bearings 14 and 15, and an unbalanced weight 17 having a center of gravity at an eccentric position between the lower end of the rotating shaft and the bearings 14 and 15, respectively.
, 18 are provided 5 and the upper end of the rotating shaft 16 is connected to the joint 1
It is connected to the rotary shaft 4 of the electric motor 5 via 9. This joint 19 connects the rotating shaft 4 side to the rotating shaft 1 through an elastic body such as rubber.
It connects the 6th side and transmits rotational torque but not vibration. 10A pair of powder containers 20A and 20B having the same shape are provided at symmetrical positions at both ends of the diaphragm 11.

Each container has a filtration net 21 stretched inside, an input port 22 in the center of the upper part, a discharge port 23 in the center of the bottom, and a discharge port with an opening 15 at the upper end communicating with one corner of the upper surface of the filtration net 21. A tube 24 is provided. 25 is an inspection window.

In the powder vibrating device configured in this way, the inlet 22
The powder and granular material is continuously or discontinuously supplied into the powder and granular material containers 20A and 20B from
Rotate the weight 1? , 18 by rotating the diaphragm 1.
1 to generate the desired vibration, the powder container 20A at both ends,
By vibrating the filter 20B, the powder on the filter net 21 is filtered and discharged from the discharge port 23, and large particles are discharged from the discharge pipe 24.

As explained above, this device uses a single vibration generator to vibrate a pair of powder and granule containers, so for example, a different powder and granule that must not be mixed can be supplied to both containers at the same time. Each of the powders can be separately filtered.

In addition, when the meshes of the filtration nets of both containers 20A and 20B are made different and used appropriately as needed, or when one container is used for grinding, mixing, etc. without a filtration net, Since each device can be used in its own way, it can be used in a wide variety of ways even though there are 15 devices in one device. As described above in the embodiments, the powder vibrating device of the present invention has a plurality of hanging rods suspended from a fixed substrate horizontally supported on a column via coil springs, and is oscillated by the hanging rods. A vibration generator is provided in the center of a freely supported diaphragm, and powder containers of the same shape are placed opposite each other at symmetrical positions at both ends of the diaphragm, so both powder containers can be used separately. It has the advantage of being able to
