0 and 40 are attached, and a non-tact operating plate 41 is attached to the same end of the lifting platform 16. Link chain 4 for moving the moving body 14
2, 42 are a pair of left and right sprocket wheels 43, 44 provided at both the front and rear ends of the rails 12, 12.
is wrapped around. Tension bolts 45, 45 are horizontally attached to the left and right upper ends of the movable body 14, and chain joints 4 are installed at both the front and rear ends of the tension bolts 45, 45.
Both ends of the link chain 42 are connected via 6,46.

Both the front and rear filter surfaces of the filter plate 10 are covered with a pair of front and rear filter cloths 50 that are interconnected at the stock solution introduction hole. Both left and right ends of the filter plate hanging rod 51 attached to the upper edge of each filter cloth 50 are connected to horizontal upper ends of inverted L-shaped spring hanging brackets 52 provided in an upright manner at the left and right upper ends of the filter plate 10. They are each suspended by springs 53 suspended from the parts.
The connecting member 54, which is a chain that connects the opposite ends of the filter cloth hanging rods 51 of the adjacent filter plates 10, is arranged so that the distance between the adjacent filter plates 10 is greater than the distance between the adjacent filter plates 10 when they are spaced apart from each other. It has a short length. Incidentally, the connecting member 54 may be composed of a rope or the like other than a chain.

Next, the operation of the filter cloth vibrating device 13 will be explained.

The movable body 14 of the filter cloth vibrating device 13 is moved by a feed drive mechanism that operates in synchronization with the movement of a filter plate moving block (not shown) after the end of press filtration, but a detailed explanation of this is omitted. . When the moving body 14 moves above the intermediate portion of the separated filter plates 10 during the plate opening process and stops, the air cylinders 3 of the left and right moving body fixing devices 36, 36
7 and 37 to press the pressure contact plates 38 against the inner surfaces of the rails 12 and 12, respectively, and move the moving body 14.
to be fixed. Next, by driving the brake motor 30, the pair of vertically driving male threaded rods 1 are connected via a power transmission mechanism provided on the upper surface of the upper wall of the moving body 14.
7 and 17 are rotated at the same time, and the elevating table 16 is lowered. The upper and lower limit positions of the lifting table 16 are set by adjusting the positions of the proximity switches 40, 40. After the lifting platform 16 is stopped at the lower limit position, the pressurizing air springs 70, 7 of the capturing means 23
Air is introduced into the terminal 0, which causes the tip brackets 69, 69 to move against the tensile forces of the left and right coil springs 75, 75. Due to the operation of the air springs 70, 70, the brackets 69, 69
At the same time, the swinging arms 67, 67 connected to the swinging arms swing, the horizontal shafts 61, 61 rotate, the wedge-shaped arms 63, 63 swing, and the pair of capture plates 64, 64 swing. These are opened outward and pressed against the inner surfaces of both the front and rear filter cloth hanging rods 51, 51. Here, both left and right ends of both filter cloth hanging rods 51, 51 are connected to a pair of connecting members 54, 54 made of chains.
Since the filter cloth hanging rod 51,
51 does not open beyond the length of the connecting members 54, 54,
For this reason, the filter cloth hanging rods 51, 51 are connected to the capture plates 64,
64 firmly caught.

Next, by driving the vibrator 22, the filter cloth hanging rods 51, 51 are caused to vibrate together via the capturing means 23. As mentioned above, the vibrator 22 has a relatively small amplitude of, for example, 2 to 50 mm, but the vibration frequency is very high, so when the vibrator 22 is vibrated, it is held tightly by the capture plates 64, 64. Since the filter cloths 50, 50 suspended from the hanging rods 51, 51 are non-rigid bodies, the vibrations applied to the filter cloths 50, 50 themselves are amplified, and as a result, the vibrations given to the filter cloths 50, 50 themselves are lower than the amplitude inherent to the vibrator 22. The cake also flutters back and forth with a large amplitude and very rapidly, giving the cake a great deal of violent shaking-off action in a given period of time. Therefore, the filter cloth 5 suspended from the filter suspension rods 51, 51
0.50 can be removed quickly and reliably in an extremely short period of time. Note that the vibrations applied to the filter cloth by the vibrator 22 are very intense as described above, but since the filter cloth hanging rods 51, 51 are firmly captured by the capture means 23, the vibrations cause noise. This will not cause any damage to the filter cloths 50, 50. Furthermore, since the coil spring 21 is attached to the vibrator mounting plate 20 as a vibration transmission prevention mechanism, transmission of the vibration of the vibrator 22 to the movable body 14 can be buffered.

After the cake removal work is completed, the air springs 70, 70
When the air inside is discharged, the coil spring 7
Due to the tensile force of 5,75, the tip bracket 69,6
9 returns to its original state, the swinging arms 67, 67
swings in the opposite direction to the above case, the horizontal shafts 61, 61 rotate, the wedge-shaped arms 63, 63 swing inward, and the capture plate 6
4 and 64 also separate from the filter cloth hanging rods 51 and 51, respectively, and return to their original states. Then, by reverse driving the brake motor 30, the filter cloth hanging rod catching means 2 is
3 is raised, and the proximity switch 4 is at the upper limit position.
Stops when 0 is activated.

A feeding drive device for the movable body 14 is provided so that the filter cloth hanging rod capturing means 23 is positioned between the filter plates 10 in the open state, and synchronized with the movement of the filter plate moving block that sequentially opens the filter plates 10. As the movable body 14 is moved, the above-described filter cloth vibration operation is automatically and repeatedly performed for each filter chamber.

7 and 8 show a second embodiment according to the second aspect of the present invention. Here, the above first
The difference from the embodiment lies in the mounting positions of the bellows-type air springs 70, 70 of the vibrator 22 and filter cloth hanging rod capturing means 23. That is, in this second embodiment, the vibrator 22 is not attached to the upper horizontal plate 26 attached to the lifting table 16 via the coil spring 21, and the lifting rod 24, A lower horizontal plate 27 is attached in a suspended manner via 24.
A vibrator 22 is attached to the top surface. Therefore, the through hole 48 formed in the lower wall of the movable body 14 is made large enough to allow the suspension rods 24, 24 and the vibrator 22 to be inserted therethrough. Further, the pressurizing air springs 70, 70 of the filter cloth hanging rod capturing means 23 are attached to the lower surface of the lower horizontal plate 27.

According to the second embodiment, since the vibrator 22 is provided below, not only can the center of gravity be lowered, but also the height of the moving body 14 can be low, making it very compact. This has the advantage that the installation height of the filter press can be lowered. In addition, in FIGS. 7 and 8, illustration of the movable body fixing device 36 and the pair of upper and lower proximity switches 40, 40 is omitted.

When electricity is applied in this state, the filter cloth hanging rods 51, 51 made of ferromagnetic material are captured by the adsorption force of the electromagnetic holders 88, 88, and the vibrator 22 is driven in this state, so that the filter cloth hanging rods 51, 51 and the filter cloths 50, 50 are vibrated together with the vibrator 22, and the cake is peeled off and removed. After removing the cake, the adsorption force of the electromagnetic holder 88 is released, and the slide cylinders 81, 81 are operated to move the lifting platform 16, vibrator 22, and capture means 80 to the upper limit shown by the two-dot chain line in FIGS. 9 and 10. be raised to a certain position.

12 and 13 show a fourth embodiment according to the first aspect of the present invention. Here, the difference from the third embodiment is in the filter cloth hanging rod capturing means 90. That is, in this fourth embodiment, three chuck devices 91 each having catch claws 92, 92 which can be opened and closed are fixed to the lower surfaces of a pair of front and rear horizontal plates 87, 87 at predetermined intervals.

Other points of the above-mentioned second to fourth embodiments are as follows:
Since this is the same as in the first embodiment described above, the same parts are given the same reference numerals in the drawings.

Note that the elevating means for the elevating platform 16 equipped with the vibrator 22 is not limited to that of the above-described embodiment, and a fluid pressure cylinder or other structure may be adopted and used as appropriate. In addition, the vibration transmission prevention mechanism and filter cloth hanging rod capture means are not limited to those shown in the drawings.
Other suitable materials may also be used.

Further, in the above embodiment, the present invention is applied to a side bar type filter press in which the filter plate is suspended by a pair of left and right side bars so as to be movable back and forth. The same applies to an overhang type filter press (not shown) which is suspended so as to be movable back and forth.

Effects of the Invention As described above, the filter cloth vibrating device for a filter press according to the first aspect of the present invention is a filter press equipped with a movable body disposed above the filter cloth hanging rod so as to be movable back and forth. A lifting platform is provided on the movable body so as to be able to rise and fall freely, and a vibrator mounting plate is provided on the lifting platform via a vibration transmission prevention mechanism.
A vibrator is attached to this mounting plate, and a horizontal plate is attached to the same mounting plate via a hanging rod, and a filter cloth hanging rod is attached to this horizontal plate to transmit vibrations from the vibrator by holding the filter cloth hanging rod. The filter cloth hanging rod is attached with a rod catching means, and after the filter cloth hanging rod catching means is lowered and the filter cloth hanging rod is firmly captured, the filter cloth is removed by a vibrator with a very high frequency. Since the hanging rod and the filter cloth are vibrated, the filter cloth can vibrate together with the vibrator, and the vibration of the vibrator is effectively transmitted to the filter cloth, and the vibration given to the filter cloth itself is Since the filter cloth is amplified, the cake adhering to the filter cloth is subjected to many vigorous shaking-off actions in the front and back directions in a certain period of time, making it possible to quickly and reliably remove the cake in an extremely short period of time. , it is possible to greatly improve the efficiency of the filter press's filtration work. This effect becomes greater as the filter press has a larger capacity and has a larger number of filter plates, that is, a larger number of filter chambers. In addition, since the filter cloth hanging rod taken from the capture means vibrates together with the vibrator, unlike the case of conventional filter cloth vibrating devices, no noise is generated due to vibration, and the filter cloth is not damaged. This has the effect of not being affected by
