FIG. 1 is a view showing an entire structure of a multifunctional filter of the present invention. FIG. 1 (a) is a front view showing a partial cross section, and FIG. 1 (b) is a side view thereof. 1 (c) shows a plan view thereof. In the example shown in FIG. 1, reference numeral 1 denotes a container portion made of a metal can made of stainless steel or the like, and a slurry supply port 2 and an inspection window 3 are provided at the upper center of the container portion 1. In addition, a discharge port 4 for discharging treated powder and the like from the inside of the container portion 1 to the outside is provided on a side surface of the container portion 1, and a heating jacket 5 used for drying is provided. Further, the washing water is supplied into the container 1.
A nozzle 6 for supplying the gas to the inside is provided.

At the bottom of the container 1, a filtration unit 11 is provided in a liquid-tight manner. In the present embodiment, the filtration unit 11 includes a bottom plate 12.
The filter cloth 14 is provided on the upper side via a spacer 13. The bottom plate 12 is provided with a pin hole through which a pin for fixing the spacer 13 and the filter cloth 14 is inserted. Also,
A flange portion 12b is provided on the periphery thereof, so that the filtrate can be discharged to the outside from a filtrate discharge port 12d through a filtrate passage 12c formed between the flange portion 12b and the lower portion of the container portion 1. It is preferable to use a Teflon spacer as the spacer 13 because better performance can be obtained in terms of corrosion resistance. Further, in the present embodiment, the filter unit 11 is configured by disposing a filter plate including the spacer 13 and the filter cloth 14 on the bottom plate 12, but a porous ceramic plate is used instead of the spacer 13 and the filter cloth 14. You can also.

A stirring blade 21 is provided in a liquid-tight manner at an upper portion of the container 1 and through the opening 1a. In this embodiment, the impeller 21 is provided with an impeller shaft 22 provided in the opening 1a in a liquid-tight and freely rotatable manner, and two hollow impellers provided at right angles to the end of the impeller shaft 22 in the container 1. Arms 23-1 and 23-2 and rakes 24 attached to impeller arms 23-1 and 23-2.
And a drive unit 25 provided above the container unit 1 of the impeller shaft 22 for rotating and raising and lowering the impeller shaft.

What is important in the present embodiment is that when the stirring blade 21 is driven at the lowest position in the center of the filtration unit 11, it engages with the center of the impeller shaft 22 to exert a steadying action. This is the point where the convex portion 26 is provided. This convex part 2
As for the shape of 6, the horizontal section is preferably circular, and the upper end is preferably R-shaped, tapered, or conical. The height of the projection 26 must be such that the rake does not come into contact with the filter plate, and varies depending on the shape of the impeller, but is preferably about 50 mm to 500 mm. The outer diameter of the convex part is 30 mm in diameter and 1 /
It is necessary to be 3, and it is desirable that the diameter is about the same as that of the impeller shaft. Further, it is preferable that the convex portion 26 be provided with glass lining or made of Teflon or ceramic.

In the multifunctional filter of the present invention having the above-described structure, the projections 26 are present at the center of the filtration unit 11 where substances such as slurry tend to accumulate at the time of filtration or stirring, so that substances such as slurry do not accumulate at all. Of the impeller shaft 22
Since the impeller shaft 22 serving as the center of rotation and the convex portion 26 are engaged during the rotation, the impeller shaft 22 and the filtration unit 11 do not touch during the rotation. Further, when the impeller shaft 22 moves up and down, the convex portion 26 also serves as a stopper when the impeller shaft 22 descends most, and can protect the rake 27 and the filtering portion 11.

The present invention is not limited to the above-described embodiment, but can be variously modified and changed. For example,
In the above-described embodiment, the impeller shaft 22 and the projection 2
6 was slid on a plane, but the impeller shaft 22
A concave portion may be provided at the center of the shaft, and the tip of the convex portion 26 may be inserted into the concave portion.
2 may be constituted by a hollow pipe and the convex portion 26 is engaged with the hollow portion. Also, in the above example,
Although the convex portion 26 has the function of engaging with the center of the impeller shaft 22 to perform steadying, it is needless to say that this function is not essential.

[0014]

As is apparent from the above description, according to the present invention, a convex portion is provided at the center of the container of the side discharge type multifunctional filter, and the slurry or the like is always provided at the center. Because it is configured so that it does not exist, the agitation and dischargeability of the central part of the container part can be improved with a simple structure, the overall height of the device can be maintained equivalent to that of the conventional side discharge type, and the role of a stopper And the filtration part can be protected. When the stirring blade is driven at the lowest position, it is preferable to engage with the center of the impeller shaft because it has the effect of preventing the impeller shaft and the filter from oscillating.
