[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a rolling granulator, particularly a bread granulator.

[0002]

2. Description of the Related Art In general, a pan-type granulator as the above-mentioned rolling granulator is prepared by continuously adding an additive liquid together with, for example, cement as a solidifying material to powder (eg, dust) in a rotating pan-type granulating dish. It supplies and discharges the powder in the form of particles. At this time, the granulator, the powder supply mechanism, the coagulation material supply mechanism, and the additive liquid supply mechanism are separately manufactured, brought into an installation location, and installed and used at the installation location. I have.

However, in general, the installation place of the rolling granulation apparatus is small, and the installation and installation of each mechanism is troublesome, and the rolling granulation apparatus is additionally installed in the existing operating incineration facility. In such a case, there is a problem that the incinerator must be shut down for a long time. In view of the above, an object of the present invention is to provide a rolling granulator that integrally assembles each mechanism together with these granulating dishes and can immediately operate just by carrying them into a place of use. I do.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is to continuously supply powder and additive liquid to an inclined pan-type granulating dish, and rotate the granulating dish to form a granulated dish. A granulator for granulating, a powder supply mechanism for the granulator, a powder mixture supply mechanism and an additive liquid supply mechanism, and these mechanisms are respectively associated with the rotation of the granulation dish. The gist of the present invention is that the granulating dish and each mechanism are mounted on a common mounting table while operating.

According to a second aspect of the present invention, the powder supply mechanism and the mixture supply mechanism are arranged on a common transfer conveyor.
The gist is that the powder and the mixed material are mixed by the conveyor and supplied onto a granulating dish.

[0006]

[Operation] The granulator, powder supply mechanism, mixture supply mechanism and additive liquid supply mechanism are mounted and integrated on a common mounting base, so that they can be used immediately by simply bringing them into the place of use. .

[Embodiment] The figure shows an embodiment of the present invention. The tumbling granulator 1 includes a bread granulator 2, a powder supply mechanism 3, a mixture supply mechanism 4, an additive liquid supply mechanism 5, and a mounting table 6 on which these are placed.

The bread-type granulator 2 includes a bread-type granulation dish 10 and a drive shaft 11 which supports the same at one end, as is well known.
The drive shaft 11 is tiltably and rotatably supported by a support member 12, and is rotated by a drive motor (not shown). 1
Reference numeral 3 denotes a dust collecting mechanism for suction-filtering dust generated during the operation of the granulating dish, 14 denotes a cover attached to the upper part of the granulating dish 10, and 15 denotes a mixing duct for mixing the cover 14 and the dust collecting mechanism 13. The other structure is the same as the well-known structure, and the detailed description is omitted.

The powder supply mechanism 3 includes a powder storage hopper 16 and
And a transfer conveyor 17 disposed therebelow.
The transfer conveyor 17 includes a lower horizontal conveyor 18, a vertical conveyor 19, an upper horizontal conveyor 20, and a horizontal transfer screw conveyor 21 that transports the pan-type granulation dish 10 to an appropriate place. The hopper 16 has a lower portion of a scraping mechanism 2 having a screw for scraping powder to a discharge port 23 on one side.
2, a discharge chute 24 connected to a discharge port 23 on one side of the scraping mechanism 22, and a discharge amount adjusting rotary valve 25 provided on the discharge chute. It is open to.
26 denotes a motor for driving the scraping mechanism 22, and 27 denotes a motor for driving the rotary valve.

Each of the lower horizontal conveyor 18, the vertical conveyor 19, and the upper horizontal conveyor 20 is constituted by a belt conveyor in which a scraping plate is attached to a flat belt at a predetermined interval, and in particular, the vertical conveyor is a bucket. It is composed of a conveyor belt. The screw conveyor 21 has a structure in which two screws are arranged facing each other,
Of course, it is not limited to this. Reference numeral 28 denotes each belt conveyor driving motor, and 29 denotes a screw conveyor driving motor. Reference numeral 30 denotes a guide cylinder that supplies the powder fed by the screw conveyor 21 into the granulation dish 10.

The mixing material supply mechanism 4 includes a storage hopper 40 for storing a mixing material such as a cement material, a chute 41 connected to a lower portion of the hopper, and a discharge amount adjusting rotary valve 42 provided on the chute 41. The chute 41 is open on the lower horizontal conveyor 18. 43
Denotes a rotary valve drive motor.

The additive liquid supply mechanism 5 includes an additive liquid storage tank 5
0, an additive liquid delivery pump 51, an additive liquid ejection nozzle 52, and a mixing pipe 5 for guiding the additive liquid to the ejection nozzle 52.
And 3. The additive liquid is a mixture of water and a chelating agent.

The bread granulator 2, the powder supply mechanism 3, the mixture supply mechanism 4 and the additive liquid supply mechanism 5 are mounted on a common mount 6. Then, an assembly test operation is performed in a manufacturing factory in advance, and then the vehicle is mounted on a medium-sized truck and transported to an installation location, and can be installed at a predetermined location.

In the above configuration, when granulating the powder, the powder in the hopper 16 is fed to the discharge chute 24 by the scraping mechanism 22, and the amount of the powder is adjusted by the rotary valve 25 via the discharge chute.供給 す る Supply continuously onto the lower horizontal conveyor 18. At the same time, the mixing material in the hopper 40 is supplied by the mixing material supply mechanism 4 to the lower horizontal conveyor 1 through the chute 41 at a predetermined ratio to the powder supply amount by the rotary valve 42.
8 on a continuous basis. Thus, the powder and the mixed material are mixed by the lower horizontal conveyor 18, the vertical conveyor 19, and the upper horizontal conveyor 20, and further stirred and mixed by the screw conveyor 21 to be supplied to the pan-type granulation dish 10.

At the same time, from the additive liquid supply mechanism 5, an additive liquid in the storage tank 50 (a chelating agent is usually added).
By a pump 51 through a mixing pipe 53
The powder is granulated by the rotation of the granulation dish 10 and discharged downward.
