本考案はフイルタープレスの原液供給路の内部
の詰まりを防止するためのフイルタープレスのエ
アブロー装置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an air blowing device for a filter press for preventing clogging inside the raw solution supply path of the filter press.

つて詰まりの防止を図つている。(Prior art) A center-feed type filter press supplies stock solution at high pressure from a stock solution tank through a stock solution supply path in the center of the filter plates into a filter chamber formed between a number of filter plates, and performs dehydration filtration. However, when the plate is opened to take out the cake after dewatering and filtration, the slurry in the stock solution supply channel may flow out and pollute the outside, or the slurry may adhere to the stock solution supply channel and gradually slow the flow. Deteriorate. For this reason, clogging is prevented by blowing air to instantly cause the slurry in the stock solution supply path to flow back into the stock solution tank using compressed air after the dewatering operation is completed.

破損が生じ易い欠点があつた。 Conventionally, the tip of the slurry transfer pipe, through which the slurry flows back during air blowing, is connected to a submerged silencer installed below the liquid level in the stock solution tank, and the slurry is directly returned to the stock solution via this submerged silencer. I was starting to be able to do it. However, if the stock solution tank is provided with a chemical-resistant lining, there is a risk that the lining will peel off due to the impact vibrations generated in the submerged silencer during air blowing. Furthermore, in order to avoid such a risk, if the pipe is inserted into the raw solution from above so as not to come into contact with the lining, there is a drawback that the slurry transfer pipe is likely to be damaged due to severe vibration.

１０の途中に形成された分岐部に接続したある。 1 is a center feed type filter press equipped with a large number of filter plates 2; 3 is a stock solution tank; the stock solution to be filtered is supplied to the stock solution supply pipe 10 by a pump 4;
It is sent to the filter press 1 via the filter plate 2, and is supplied into the filter chamber from the stock solution supply path in the center of each filter plate 2. Reference numeral 5 is a compressed air source for air blowing, which sucks high-pressure compressed air into the flow path in the center of each filter plate 2 of the filter press 1 through an air blow pipe 6 after the dehydration filtration or compression process is completed, and causes the air to remain in the stock solution supply path. The slurry flowing therein is caused to flow back toward the slurry transfer pipe 7. The slurry transfer pipe 7 is connected to a branch part formed in the middle of a stock solution supply pipe 10 that connects the stock solution tank 3 and the filter press 1.

The tip is connected to this eliminator 8. As shown in the figure, the eliminator 8 has a large number of gas-liquid separation plates 9 installed in the case, and when the air-blown slurry collides with the gas-liquid separation plates 9, gas-liquid separation occurs, and only the slurry flows downward. The structure is such that the air falls into the stock solution tank 3 and escapes into the atmosphere.

ブロー装置と変わるところはない。(Function) In the device configured as described above, the stock solution supplied from the stock solution tank 3 is sent to the filter press 1 through the stock solution supply pipe 10, and the stock solution is fed into each filter chamber from the stock solution supply path formed in the center of the filter plate 2. After the compressed air is supplied and compressed and filtered, high-pressure compressed air is introduced from the compressed air source 5 into the raw solution supply channel to cause the slurry remaining inside to flow back, which is different from conventional air blowing devices of this type. There is nothing that will change.

Of the slurry in the stock solution supply pipe 10, that on the tip side from the branching part is also blown to the eliminator 8 through the slurry transfer pipe 7. Then, the pressure of the air blow is released to the atmosphere from between the many gas-liquid separation plates 9, and only the slurry flows down to the raw liquid tank 3 installed below.

Since there is no risk of impact being applied to the inside, the lining inside the stock solution tank 3 will not peel off or the slurry transfer pipe 7 will not be damaged due to vibration. In addition, the slurry transfer pipe 7 etc. are connected to the stock solution tank 3 and the filter press 1.
Since it is connected to a branch part in the middle of the stock solution supply pipe 10 that connects the stock solution supply pipe 1 to the filter press 1,
The slurry inside 0 is also removed by air blowing. Moreover, since the backflowing slurry is reliably collected in the stock solution tank 3, there is no loss, and it is also economically efficient.
