BRIEF DESCRIPTION OF THE DRAWINGS FIG. In this example shown in FIGS. 1 to 3, 1 is a filter plate,
Reference numeral 2 denotes a filter frame, which is a double filter press having a filter frame 2 interposed between a number of parallel filter plates 1, and each of the filter plates 1 and the filter frame 2 has arms 11, 21 on both sides thereof. Outside
It protrudes toward .

[0008] In addition, upright pieces 12, 22 are projected upward from the projecting ends of the arms 11 , 21 , and the upright pieces 12, 22 are protruded.
Hanging pieces 13 and 23 projecting inward from the upper end of 22 are provided. And, at the lower ends of the hanging pieces 13 and 23,
The sliding members 15 and 25 made of stick are provided as engaging members.
The engaging members 15, 25 are set on both sides of the filter plate 1 and the filter frame 2, respectively.
Of the filter plate 1 and the filter frame 2 above the arms 11 and 21
It is engaged with the upper part of the suspension rail 3 arranged along the parallel direction.
You.

The hanging pieces 13 and 23 are
1 and 21, the space K between the inner end of the hanging pieces 13 and 23 and the side end face of the filter plate 1 or the filter frame 2.
Is formed. Reference numeral 4 denotes a cleaning nozzle of the cleaning device, which is movably disposed above the filter plate group.

Reference numeral 5 denotes an upper cover body for covering the filter plate group together with the washing nozzle 4 at the time of washing . Reference numeral 6 denotes a lower cover disposed outside the rail 3. Further, although not shown, the filter plate 1 and the filter frame 2 are connected to each other with chains before and after each other, and are provided with a pressurizing device for compressing an end portion of the filter plate and a filter plate opening device.

The operation of the present embodiment will be described below. A filter cloth 10 is applied to each filter plate 1, and the slurry is formed by the filter plate and the filter frame while the filter plate and the filter frame are pressed as in the conventional case. Each of the filter chambers is driven into each of the filtration chambers for filtration, the respective filter plates 1 and the filter frames 2 are opened, and the filter cake is dropped and removed.

A characteristic of this embodiment is that, after removing the filter cake, the filter cloth 1 of the filter plate 1 is washed by the washing nozzle 4 as shown in FIG.
When the cleaning is performed by injecting water into the water, the upper cover body 5 is prevented from scattering on the sliding pieces 15 and 25 and the rail 3.

That is, since the hanging pieces 13 and 23 are connected to the upstanding pieces 12 and 22 from the arms 11 and 21 projecting from both sides of the filter plate 1 or the filter frame 2, the hanging pieces 13 and 23 are provided. , 2
A space K is formed between the inner end portion of the upper cover 3 and the filter plate or the filter frame, and the sliding pieces 15 and 25 are provided by inserting the side surface of the upper cover body 5 into the space K from above. The hanging pieces 13 and 23 and the rail 3 are located outside the upper cover body 5. Therefore, the washing water does not scatter to the sliding pieces 15 and 25 and the rail 3.

The washing water radiated to the lower portions of the filter plate 1 and the filter frame 2 is not scattered outside by the lower cover 6. The filter plate 1 and the filter frame 2 are placed on the lower cover body 6.
Since the upright pieces 12 and 22 are exposed, the open plate position can be determined.

Although the present embodiment has the above-described configuration, the present invention is not limited to this. For example, regardless of the configurations and shapes of the filter plate and the filter frame, a single-type filter press without a filter frame as in FIGS. 5 and 6 may be used.

The shape of the arm protruding on both sides of the filter plate or the filter frame, the shape of the upright piece protruding from the arm, and the shape of the hanging piece protruding from the upright piece are also appropriate. Further, the hanging pieces may be protruded outward as shown in FIG. In addition, the configuration of the engaging member provided on the hanging piece is also arbitrary, as long as it can be engaged with the hanging rail, and other than the sliding piece, a rolling element such as a roller may be used.

[0017]

According to the first aspect of the present invention, a single filter press is secured inside the suspension rail 3 .
Since the side surface of the upper cover body 5 can be arranged in the space K ,
The hanging piece 13 provided with the engaging member 15 and the rail 3 are on the upper side.
Since the filter cloth 10 is located outside the cover body 5 , when the filter cloth 10 is washed, the washing water does not scatter to the engaging members 15 and the rails 3 to prevent clogging, and the filter plate 1 moves smoothly. Can be secured. In claim 2, the hanging piece 13 is filtered.
The filter plate 1 can be moved stably near the side of the plate 1 .

According to a third aspect of the present invention, the upper part of the space K secured inside the suspension rail 3 in the double type filter press.
Since the side surface portion of the cover body 5 can be arranged, the engagement members 15,
Top cover is lowered pieces 13, 23 and rails 3 suspended with 25
Will be located outside of the bar member 5, during washing of the filter cloth 10, the washing water is not to be scattered to the engaging members 15, 25 and the rail 3 can prevent clogging, the filtration plate 1 and filtration Frame 2
Can be ensured smooth movement. In claim 4, the suspension
The lower piece 13, 23 is able stably move the filter plates 1 and 濾枠2 made close to the side of the filtration plate 1 and 濾枠2.
