Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rectifier plate suitable for use in drying or cooling powdered or granular materials by nitrogen flow.

[Conventional technology and its problems]

FIGS. 5 to 7 show a conventional rectifying plate 5I, in which a large number of semicircular circles are lined up in parallel iC, and slits serving as through holes are completely formed between them. A plurality of lips 14 extending perpendicularly to the longitudinal direction of a large number of flat plates 4υ
A flat plate (4υ is reinforced by IJ).

A flat plate (the width of 4υ is about 25mm, for example, a slit for K) (
6) has a width of approximately 0.8 to 1.0 mm''C (ignored to the size ratio to make the diagram easier to understand), hot air is blown from below and rectified by the slit (6). Even though it is not shown in the figure, there is a powder-like material on the current plate T0n, and it is transported to the right by the movement of the current plate 6I in the diagonal direction a. During transportation, it is fluidized and dried by rectified hot air.

However, powder with a particle size smaller than the width of the slit is fluidized by the hot air that blows up, and is directly blown away.
3. Items that do not fall below the rectifier map may end up falling downwards, causing problems with this process.

[Problem that the invention seeks to solve]

The present invention 8A was developed in view of the above-mentioned problem Kgfi, and its purpose is to provide a rectifier plate that does not fall downward even when powder or micro-particles having a particle size smaller than the width of the slits.

[Means for solving problems]

The above purpose has a large number of through holes, and the holes g f from below.
i iThe through hole (v which was made to rectify the flow and guide it upward)
5. This is achieved by a rectifying plate characterized in that the face plate is bent in the above-mentioned inner part 7 (1).

[For production]

Although the material on the baffle plate is fluidized by the airflow from below, particles or powder smaller than the width of the through hole are deposited at the bends of the through hole and do not fall below the baffle plate. Alternatively, powder or grains deposited on the bending portion are blown up above the current plate by an air flow from below.

〔Example〕

Hereinafter, a photographic dryer to which the current plate according to the embodiment of the present invention is applied will be described with reference to FIGS. 11J to 4.

In the figure, the vibratory dryer is shown as a whole (II) and is sealed by a trough (2) μ hood (3). μ openings (4m) (4h) are formed in the hood (3), these K are It is assumed that a duct, a suction machine, etc. are connected even if not shown.A material supply port (5) is also formed in the hood (3), from which powder and granular materials are simultaneously fed. A material discharge port (6) is formed at the right end.

Hot air inlets (7a) (7b) are provided on both side walls of the trough (2).
) are formed, and these include piping (8a) shown in simplified form.
(8b) and the hot air supply pipe (9) are connected. Rubber bushings (11) for shock mitigation are attached to both side walls of the top (2) via mounting plates OQ, but these are attached to the flat plate 041 CLI (13 and the rubber plate (15a) held by these). (15h), the flat plate (6) 03 is fixed to the mounting plate QO, while the inner flat plate a< is fixed to the drive rod (4).

The drive rod (6) is pivotally connected to the crank part σ7)K, and the crank part α7) is connected to the motor Q! through the bell)Qllk. Rotationally driven by 19. It is connected to the trough (2) by a counterweight tray i-(A) and a coil spring (211).

That is, the trough (2) is supported so as to be able to vibrate in the direction of arrow a. The counterweight is attached to the anti-vibration coil spring.
supported on the ground.

Inside the trough (2), a straightening plate (2), clearly shown in FIGS. 2 to 4, is attached via a mounting member (B).

This rectifying plate ■ creates a space Q on the hot air introduction side inside the trough (2).
4I and a hot air outlet space 5. Current plate C3 [
J is a member C whose cross sections are arranged in parallel and have the shape shown in Fig. 4.
31], and a through hole C3 is formed by mislit Ki between these. A large number of members (311 are reinforced with a plurality of ribs extending in the material transfer direction), through holes (33 are formed in a crank shape as shown in Fig. 4, upper vertical part (32a), horizontal It consists of a part (32b) and a lower vertical part (32), and the hot air blown up from below as shown by the arrow is rectified by the through hole G3 and guided to the upper part 6.The rectifier plate is not shown. It is always bent in an inverted shape at the right end in FIG. 1, and the soil material is guided to the above-mentioned material discharge port (6).

The embodiment of the present invention is constructed as described above, and its operation will be explained next.

The particulate material introduced into the supply port (5) is transferred to the right by vibration on the current plate q within the trough (2).

Heat is blown up from below the rectifying plate and is rectified through the through holes, where it animates the powder and granular material being transported, heat exchanges it, and heats it to dry it.

Among the fluidized skin powder granular materials, powder or grains having a particle size smaller than the width of the through hole fall into the through hole. However, these particles fall onto the horizontal part (32b) of the through hole (33) and do not fall to the lower vertical part (32h).
Even if it does not accumulate on top, the hot air blowing up from below will blow it up again above the rectified root wall.

The heated and dried material is taken out from the material outlet (6). Due to the above-mentioned action of the rectifying plate (2), almost no powder or grains fall below this plate, and all the materials are discharged to the outside from the material discharge port (6).

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the longitudinal valley member CD constituting the rectification source is made up of a single member, but the nVC is not limited to this, and may be made up of a plurality of members, for example, two members. Further, the shape of the through hole c3z is not limited to that shown in FIG. 4, and may be, for example, one in which the total number of bent portions is further increased.

In the above embodiments, a dryer is described, but the present invention may also be applied to a cooler using cold air. Alternatively, it may be applied to a simple fluidized bed.

〔Effect of the invention〕

As described above, according to the current plate of the present invention, even fine powders and particles can be fluidized by air flow without falling downward. Therefore, maintenance of equipment and equipment using this rectifying plate becomes easy.
