この発明は、フイルタープレスの運転方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method of operating a filter press.
フイルタープレスは、一般的に、複数枚の板
を接離自在に配列して各板間に室を形成する
と共に、各板相互間に一対の布を挾み、各
板に給泥口を連通して設け、この給泥口から板

Generally, a filter press has a plurality of plates arranged so that they can be moved toward and away from each other to form a chamber between each plate, and a pair of cloth is sandwiched between each plate, and a slurry supply port is connected to each plate. The sludge is forced into the chamber between the plates through this sludge supply port.
ところで、各板に形成された給泥口には、汚
泥内の夾雑物や各室内の布のたるみあるいは
皺などの原因によつて過工程中に詰まりが発生
することがある。このように給泥口に詰まりが発
生すると、給泥口が狭くなり、室内に供給され
る汚泥量が少なくなると共に、汚泥の入りやすい
室、入りにくい室の差ができることにより
室間の過圧力に差ができ、この過差圧によつ
て板が破損するおそれがある。 By the way, the sludge supply ports formed in each plate may become clogged during over-processing due to foreign matter in the sludge or slack or wrinkles in the cloth in each chamber. If the sludge supply port becomes clogged in this way, the sludge supply port becomes narrower, reducing the amount of sludge supplied into the room, and creating a difference between the chambers where sludge easily enters and the chambers where sludge does not enter, resulting in overpressure between the chambers. There will be a difference in pressure, and this excess pressure may cause damage to the plate.
そこで、この発明は、過工程中に、給泥口の
詰まりを清掃して各室内に供給される汚泥量を
均一化し、室間の過差圧をなくそうとするも
のである。 Therefore, the present invention attempts to eliminate the excess pressure difference between the chambers by cleaning the clogging of the sludge feed port during the over-step to equalize the amount of sludge supplied to each chamber.
上記の問題点を解決するために、この発明は、
汚泥の給泥を断続的に行ない、給泥停止中に、給
泥口へ圧縮空気を吹き入れるようにしたものであ
る。
In order to solve the above problems, this invention
Sludge is supplied intermittently, and compressed air is blown into the sludge supply port while the sludge supply is stopped.
このように、過工程中に給泥を一旦停止し
て、給泥口へ圧縮空気を吹き入れると、過内圧
が下がると同時に空気の圧力により室内の詰ま
りが除去される。
In this way, if the mud supply is temporarily stopped during the over-step and compressed air is blown into the mud supply port, the excess internal pressure is reduced and at the same time the air pressure removes the clogging inside the room.

る。 That is, an upper frame 3 is spanned over a pair of left and right frames 1 and 2, and a plurality of plates 4 are supported by this upper frame 3 so as to be able to move toward and away from each other. A chamber 5 is formed between the plates 4, and a pair of cloths 6 are sandwiched therebetween. Each plate 4 has a mud supply port 7.
are arranged in communication. A sludge feed valve 8 and a sludge drain valve 9 are provided at one end of the sludge feed port 7, and a sludge charging pump 10 is connected to the sludge feed valve 8. Further, the other end of the mud supply port 7 is connected to a compressed air source (or tank) 12 via a blow valve 11 . Each of the plates 4 is tightened by a hydraulic cylinder 13 via a tightening plate 14.

る。 In the overstep, each plate 4 is tightened by the hydraulic cylinder 13, the sludge drain valve 9 and the blow valve 11 are closed, the sludge feed valve 8 is opened, and the sludge is pumped through the sludge feed port 7 by the sludge feeding pump 10. Press fit into each chamber 5. The liquid 15 is discharged from the water collection groove 16.

ときに行なうようにしてもよい。 In this invention, the above-mentioned over-step sludge supply is performed intermittently, and while the sludge supply is stopped, the sludge supply valve 8 is closed, the sludge drain valve 9 and the blow valve 11 are opened, and compressed air is supplied through the blow valve 11. Air is blown into the mud supply port 7 from the source (or tank) 12. As a result, the overpressure in each chamber 5 is temporarily reduced as shown in FIG.
Even if there is a blockage, the blockage is broken up and discharged by the blown air, and the mud supply port 7 is unclogged. The blowing of air into the mud supply port 7 may be carried out at fixed time intervals (△t), or the pressure within the chamber 5 may be set and the blowing may be carried out when that pressure is reached. .

According to this invention, the sludge supply port is cleaned and the clogging of the sludge supply port is removed during the over-process, so that sludge is uniformly supplied into each chamber. Therefore, no differential pressure is generated between the chambers, and damage to the plates can be prevented, and since sludge is sufficiently supplied to each chamber, the throughput can be increased.
