[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a filter peeling device for a filter press using a metal mesh as a filter material, and more particularly to a device for peeling a cake adhered to the filter material by vibrating. Regarding improvement.

[0002]

2. Description of the Related Art Japanese Patent Publication No. Sho 60-22971 discloses a conventional technique for separating a cake by vibrating a filter medium. In this invention, a filter cloth is used as a filter medium, and in order to vibrate the filter cloth, a vibrating device is moved and used for each filter plate.

[0003]

In [devised is to solve the above described conventional apparatus, such as may take time to a vibrating device for separating the cakes without must be moved for each filtration chamber, also, the vibrating device itself that There was a disadvantage that it became expensive including the moving mechanism.

[0004]

Therefore, in the present invention,
A metal mesh with good cake peeling properties is used as a filter medium, and the time required for peeling is greatly reduced by vibrating each filter plate all at once or in block units so that the cake can be peeled accurately. The point is that a large number of filter plates are movably juxtaposed on a horizontally provided guide rail, and these filter plates are closed to form a filtration chamber between the respective filter plates. In a filter press in which each filter plate is opened to remove cake generated in each filtration chamber, an auxiliary rail is mounted on the guide rail via a spring , and a vibrator is arranged on the auxiliary rail.
In both cases, a metal mesh is stretched on the filtration floor of the filter plate,
The support arm of this filter plate is mounted. In the case of a large machine, if the auxiliary rail is divided and used in the length direction, a small vibrator is sufficient.

[0005]

The peeling device according to the present invention uses a metal mesh having a good cake peeling property as a filter medium as described above. Therefore, by opening the filter plate, the cake formed by opening the lower part of the filtration chamber is opened. Most of them are exfoliated and removed by weight. Then, the cake does not fall by only the Kaihan by vibrating the auxiliary rail, filter plate is peeled fall vibrates. If this lot of number of filter plates in filter plates large filtration machine pressurized Futoki of lever is vibrated divided multiple filter plate a few blocks, dropped by dividing the filtration plates of cake
And reduce the load on the conveyor
Can be. Hereinafter, the present invention will be specifically described with reference to the drawings.

[0006]

FIG. 1 is a schematic side view of a filter press according to the present invention. In FIG.
Guide rails bridged between these frames 1.1, 3
Is a filter plate movably mounted on the guide rail 2,
These filter plates are connected to each other by a chain 4 so as to open and close at the same time. (The open / close drive device is not shown.)

Next, the support structure of the filter plate 3 will be described. As shown in FIG. 2, the left and right support arms 3a of the filter plate 3 are provided with rollers 3b, respectively. Auxiliary rail 5 provided on guide rail 2
It rolls on the top. And the auxiliary rail 5
Are resiliently locked on the guide rail 2 via a spring 6 , and a vibrator 7 is provided on the auxiliary rail 5.
The vibration of the vibrator 7 is located below the auxiliary rail 5.
Increasing a spring 6 provided, beneath the heavy filter plate 3
It is made to vibrate from. In addition, there are many filter plates 3
In the filter of the type, the auxiliary rail 5 is divided in its length direction, and a vibrator 7 is provided for each of the divided pieces. May be sufficient . Reference numeral 8 denotes a metal mesh stretched on the filtration bed.

[0008] Incidentally, reference numeral 9, guide stand erected on both shoulders of the filter plates 3, 10 is a guide bar inserted through the left and right guide stand 9, stretched filter bed of the filter plate 3
Guides the upper end of the metal mesh 8
I will elastically support it with a spring inserted into the stand 9
I'm trying. Reference numeral 11 denotes a supply hole for the stock solution.

The device according to the present invention is constructed as described above. Therefore, by opening the filter plate 3, the lower part of the filtration chamber formed between each filter plate is opened, and the metal mesh 8 is opened. to case formed key is removed and dropped by peeling by its own weight. That is, because of the use of good metal mesh 8 cake peelable as filtration media, is to fall without being left to the network th its Messhiyu.

[0010] However, if no stripping alone Kaihan cake or the like having a tackiness, by vibrating the auxiliary rail it is possible to vibrate the filter plates 3, even cake clogged mesh th Metarumesshiyu 8 peeling And let it fall. That is, by vibrating the auxiliary rail 5 by actuating the vibrator 7, filter plates 3 are those which can also be peeled off up to case key which clogged the meshes of the metal mesh 8 vibrates. In vibrating the filter plate, in the present invention, the auxiliary rails 5 are provided separately in the longitudinal direction.
Number of filter plate 3 which it is to be vibration for vibrating the only filter plate 3 located above are those which can be selected Ri by the desired. The roller 3b vibrates the auxiliary rail 5.
And the roller 3b rolls to tilt the filter plate 3 back and forth.
Since the filter plate 3 is vibrated while the filter plate 3 is vibrating, the filter plate 3 is effectively excited.

[0011]

[Effect of the invention] As described above, this invention is on the guide rail.
Attach the auxiliary rail to the auxiliary rail
The vibration of the vibrator is
And the filter press machine
Transmission of vibrations to the body can be prevented by springs
You. Then, vibrate the auxiliary rail supporting the filter plate.
Therefore, the vibration of the auxiliary rail can be transmitted to the filter plate as it is.
It can be. Also, extend the auxiliary rail in the length direction.
If it is divided into a plurality, only a small one is needed
If the auxiliary rail is vibrated sequentially, the conveyor for discharging
Can reduce the load. Then, obtained by allowing a completely cake peeling by vibrating the filter plate was stretched a good metal mesh peeling cake, to solve the problems of the greatest difficulties is a cake peeling of conventional filter press The metal mesh is excellent in heat resistance and strength as compared with the conventional filter cloth, and can also improve the versatility of the filter press.
