Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution device for bulk handling, which is a device for performing distribution in two directions and simultaneous discharge in both directions by rotating a direction switching rotor.

[0002]

2. Description of the Related Art In various fields such as compounded feed, food production, pharmaceutical production or mining industry, it is necessary to prepare and distribute powder and granules.
Conventionally, as a device for transferring the minus part of the granular material from a storage tank or the like to a plurality of receivers or the like, a tank lower discharge port is divided into two or more, and a slide gate is provided for each, or a switching damper is used. Alternatively, equipment equipped with a screw feeder has been used.

[0003]

The switching damper and the screw feeder can be distributed in one direction on one side, but it is difficult to discharge them in both directions simultaneously. Further, in the slide gate, the granular material may blow out from the gap due to the pressure difference between the inside and the outside. Further, in the slide gate and the screw feeder, powdery particles are likely to remain in the device part.

In a plant that handles many kinds of powder and granules, if powder and granules remain inside the equipment, a contamination problem occurs. Therefore, the previous product is completely discharged before the next product is taken out. I have to handle it.

Therefore, an object of the present invention is to solve the above-mentioned problems, and when the powder or granular material is distributed from a storage tank or the like to two containers or the like, the two particles can be simultaneously or separately provided in two containers as desired. It is an object of the present invention to provide a dispensing device that can discharge the powder into the discharge path, and in which there is no possibility that the powder or granular material remains in the discharge path.

[0006]

In order to achieve the above-mentioned object, the present invention is directed to a distributor main body having two branch passages as a discharge part, and a reverse device arranged above the branch passages in the distributor main body. A Y-shaped truncated cone-shaped inner cylinder, and a powder which is arranged at a branch point between a branch passage in the main body of the distributor and the inner cylinder and is collected and dropped toward the inside of the lower part of the inner cylinder. And a rotor which is rotated and positioned so as to switch the discharge direction of the particles and discharge the particles to either one of the branch passages or both of the branch passages at the same time. It is a thing.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION FIG.
As shown in, the granular material (2) stored in the storage tank (1)
Is cut out by the cutting device (3) attached to the lower part of the storage tank, and either one of the two branch passages (A, B) of the inverted Y-shaped discharge part of the powder / particle distribution device (4) is The structure is such that it can be discharged from both of them at the same time, and that no granular material remains in the discharge path.

As shown in FIG. 2, a direction switching rotor (10) is provided at the branch point, and in the case of one-way discharge (the A side discharge is shown), the rotor is fixed in the state of FIG. Here, the rotor (10) has, for example, a structure in which two bent plates are attached at both ends. The powder particles cut out by the cutting device (3) are collected in the inner direction of the inner cylinder (9) having a truncated conical shape and discharged to the A side by the fixed rotor. In this case, the rotor (10) is fixed at a fixed angle θ, that is, a position where the inclination with respect to the horizontal plane is larger than the repose angle of the granular material. In addition, the branch path (A,
The branch path angle θ ′ in B), that is, the inclination of the lower side wall of the branch path with respect to the horizontal plane is also configured to be larger than the repose angle of the granular material.

As described above, both the fixed angle θ of the rotor (10) and the branch path angle θ ′ of the powdery or granular material distributing device (4) are larger than the repose angle of the powdery or granular material. No powder particles are accumulated or remain.

Discharging to the B side is possible in the same manner as the A side by fixing the direction switching rotor (10) at a position symmetrical with respect to the vertical line passing through the center of the rotor in FIG.

Referring now to FIGS. 3 and 4, FIG.
FIG. 4 and FIG. 4 are views for explaining a switching operation of the switching rotor and a mechanism for positioning. As shown in FIG. 3 and FIG. 4, the rotor (10) is fixed to the rotary shaft (11), and the rotary shaft (11) projects from both sides of the powder and granule distributor (4) to both sides. Bearing provided 1
A sprocket (12) is fixed to one end (the left end in the figure) of the rotary shaft (11) supported by the bearings 3 and 14.
A chain (not shown) is hung on the shaft, and the chain is hung on the shaft of a motor (not shown). Therefore, the switching rotor (10) transfers the rotary motion from the motor to the chain, the sprocket (12), the rotary shaft (1).
It is rotated by being transmitted via 1).

A position bar (16) is fixed to the other end (the right end in the figure) of the rotary shaft (11), and the position bar (16) extends in the longitudinal direction of the rotor (10). It is fixed to the rotary shaft (11) so as to be in the same direction as the direction. Two proximity switches (15) -A and (1) for fixed positioning of the rotor
5) -B are provided in the body of the powder- or granular-material distributor (4) so as to be adjacent to the rotating area of the position bar (16), and their positions are those shown in FIG. Corresponding to the line symmetric position of. A seal (17) is provided on the rotary shaft (11) to prevent the particles from scattering from the distributor.

When discharging in the A direction, the rotary shaft (11) is rotated and the position bar (16) is moved to the A direction.
When the side fixing proximity switch (15) -A is rotated to the position, the rotation is stopped and the rotation shaft is fixed at that position, so that the direction switching rotor is fixed, so that the discharge in the A direction becomes possible.

When the position of the position bar is rotated to the B side fixing proximity switch (15) -B, the discharge in the B direction is stopped and fixed.

Simultaneous discharge in both the A and B directions is possible by rotating the direction switching rotor. However, when the direction switching rotor is rotated in one direction, the amount of distribution is offset. Therefore, by sequentially repeating the clockwise rotation (forward rotation) and the counterclockwise rotation (reverse rotation) in FIG. 2 by the timer control, it is possible to perform simultaneous discharge in both directions and substantially even distribution in both directions.

[0016]

EFFECTS OF THE INVENTION With the powdery- or granular-material distributing device of the present invention, when powdery or granular materials are discharged from a storage tank to two storage tanks (storage tanks A and B) or the like, both can be used simultaneously or in one direction, as desired. It is possible to carry out the discharge only or sequentially and independently. In this case, level meters are installed in the two storage tanks on the downstream side,
By stopping the operation of the cutting device and controlling the rotation state of the direction switching rotor, it is possible to unmanned the powder / particle distribution facility. Needless to say, in this device, there is no concern that the powder or granules will blow out, and the powder or granules will not accumulate or remain in the discharge route.
