Before the drying and granulation process, in order to achieve the airtight effect, the bottom barrel 12 is moved upward by using two hydraulic cylinders 16 respectively connected to the outer sides of the bottom barrel, and the drum is placed above the casing. 13. The middle bucket 14 and the filter bucket 15 complete a bucket action. The conventional granulator further comprises a sieve mesh disposed on the bottom 131 of the drum 13, so that the powdery raw material can be stored in the drum in advance by inhalation 'to be carried out (4) and granulated (4) It can be __ 13 (four) to obtain granules (not shown). The above-mentioned conventional granulator does achieve the granulation function, but there is still a problem that some of the powdery raw materials placed in the hopper 3 do not participate in the drying and granulation process. Referring to FIG. 2, the reason is that hot air continues to flow forward from the air supply port m on the bottom tub 12 after being fed to the bottom tub 12, and has a flow velocity continuously until it touches the bottom tub 12 - the opposite side After ι23, the turn flows upwards. At this time, the hot air only flows into the vicinity of the opposite side 123, the second division net area 124 enters the bucket, and the portion of the powdery material that rises above the screen area m rises and spreads. However, part of the powdery raw material located above the screen area 125 adjacent to the delivery week 200806941 122 cannot participate in the drying and granulation process because it has not risen and spread, and may even be covered by the fallen granules. [Invention] SUMMARY OF THE INVENTION It is an object of the present invention to provide a bottom barrel unit for a dispersible gas stream of a granulator which can increase the proportion of powdered material involved in the drying and granulation process.

The bottom barrel unit is disposed below the drum unit and includes a barrel and a dispersing air flow assembly. The barrel body includes a bottom wall and a peripheral wall that cooperates with the bottom wall to define an opening upwardly. The chamber has an air supply opening communicating with the air chamber. The dispersing air flow assembly is radially disposed within the air chamber of the tub and includes a shunt disk interposed between the air supply port and the drum unit. The shunt disk has a peripheral edge ′ which is close to the inner wall surface of the peripheral wall and a plurality of air guiding channels 4 which are arranged on the inner side of the peripheral edge and are arranged in a light-like manner. The air supply σ leads the gas in the air chamber to flow through the air. The air guiding channel enters the drum unit. The effect of the invention is that the gas introduced into the gas chamber from the air supply port will flow through the air guiding channel of the shunt disk into the drum unit, so that the powdery raw materials in the material tank can be uniformly spread and spread. The purpose of the present invention is to improve the ratio of the powdery raw material to the drying and granulation process. [Embodiment] 200806941 The foregoing and other technical contents, features and effects of the present invention are described below with reference to the drawings. A detailed description of a preferred embodiment will be apparent. Referring to Fig. 3, the bottom barrel unit 3 of the dispersible air flow of the present invention is mounted on a granulator 2 1, and the granulator 2 is provided with two upright and parallel supports, and is detachably and combinally disposed from the bottom to the top. A bucket unit 22 between the support frames 21 has a barrel unit 23 and a filter barrel single/24. The bottom tub unit it 3 is disposed below the bucket unit 22. Before the drying and granulation process: in order to achieve the airtight effect, use the two linseed 25 • respectively to lift the connecting beam 251 on the outer side of the 7G 3 outside the bottom of the bottom barrel and drive the bottom barrel unit 3 to move upwards. The bucket top unit 22, the middle barrel unit 23' and the barrel M24' are completed in the top position and the top barrel is moved. The granulator further comprises a screen 26 disposed at a bottom of the drum unit 22, so that the powdery raw material (not shown) can be pre-positioned in the drum unit 22, after being dried and granulated. Granules (not shown) may be taken in the drum unit 22. Referring to FIG. 4, the bottom tub unit 3 includes a tub body 4, a support assembly 5, and a dispersing air flow assembly. The barrel body 4 includes a bottom wall 41 and a peripheral wall 42 that cooperates with the bottom wall 41 to define an air chamber 43 having an opening upward. The bottom wall 41 of the barrel body 4 has a connecting portion connected to a bottom end of the peripheral wall 42. 4 ιι and a spoiler 413 extending inwardly and upwardly from the inner periphery 412 of one of the distal connecting portions 411. The peripheral wall 42 has a vent 421 formed on one side and connected to the plenum 43, and a socket 423 which is mostly arranged in a bad manner on one of the inner walls 422 of the peripheral wall 42. The support member 5 is disposed in the plenum 43 of the barrel 4 and includes a two-phase 7 200806941. The opposite end is fixed to the support frame 51 of the peripheral wall 42 of the barrel 4, and the center of the support frame is upwardly The extended column 52, and the disk holder 53 fixed to the top of the column. Referring to Figures 4 and 5, the dispersing airflow assembly 6 includes a shunt disk 61 interposed between the air supply port 421 and the drum unit 22, and an annular outer ring 62 disposed on the shunt disk 61. The splitter disk 61 has a shaft plate 6 ι which is disposed above the disk holder 53 and is locked with the disk holder 53 by a plurality of screws 54, and is mostly connected to the outer periphery 612 of the shaft plate 611 and is centered on the shaft 611. Radially arranged splitter vanes 613. Each of the splitter vanes 613 has an end edge 616 adjacent to the inner wall surface 422 of the peripheral wall 42. The end edges 616 together form a shunt disc periphery 614 that is adjacent to the inner wall surface 422 and is positioned and positioned on the retaining seats 423. The outer ring 62 is coupled to the end edges 616. Alternatively, the outer ring 62 may be coupled to only a portion of the end edges 616. An air guiding channel 615 is defined between each of the two adjacent flow dividing blades 613. Referring to FIG. 5 and FIG. 6, each of the dividing blades 613 further has an outer peripheral edge 612 of the shaft plate 611 extending toward the end edge 614. The flow restricting portion 617 and a flow guiding portion 619 extending downward from the radial side edge 618 of the blocking portion 617 and extending in the direction of the air channel 615. There is a blocking portion 617 and an air guiding channel 615 between each two-phase adjacent flow guiding portion 619. Further, there may be one or more flow blocking portions 617 and one or more air guiding channels 615 between each two-phase adjacent flow guiding portions 619. Referring to Fig. 7', the gas introduced into the gas chamber 43 by the air supply port 421 continues to flow forward because of the flow velocity until the bottom wall 41 is touched to disturb the flow of the 200806941 portion, and then turns upward to be contacted. The disk 6i, the gas is guided along the guiding channels 619 through the air guiding channels 615, and uniformly dispersed into the screen 26 and blows up the powdery material located above the screen 26 to cause it to spread and spread. . In summary, the bottom barrel unit of the dispersible air flow of the granulator of the present invention has a gas in which the gas introduced into the gas chamber is dispersedly flowed into the drum unit and blown up over a large portion of the screen. The raw material is allowed to rise and diffuse to increase the proportion of the powdery raw material involved in the drying and granulation process, and the object of the present invention can be achieved. However, the above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent change and modification according to the scope of the patent and the description of the invention in the present invention. All remain within the scope of the invention patent.
