この考案はフイルタープレスにおいて開板時に
濾板、濾枠を洗浄水の噴射によりスプレー洗浄す
る装置に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for spray cleaning a filter plate and a filter frame by spraying washing water when opening the plates in a filter press.
複数枚の濾板を有してる単式フイルタープレス

In a single filter press that has multiple filter plates, the filter plate is opened one by one by a plate opening device to remove the filter slag, and then washing water is sprayed from a nozzle to wash away the residue adhering to the filter cloth. Some had conventional cleaning equipment installed. The automatic cleaning device had a traveling truck installed above the filter press, and a nozzle was suspended from the truck between the filter plates to perform automatic spray cleaning.
一方、複式フイルタープレスは複数枚の濾板の

場合は濾布を平坦面に張れるので濾過時に濾布に
掛る負荷は少なく濾布が傷みにくい利点がある。
また平坦な濾布からは濾滓の離脱が容易であるの
で残滓の付着量は少ない利点もある。このため従
来の複式フイルタープレスは上記のような自動洗
浄装置は設けられていなかつた。 On the other hand, in a double filter press, a filter frame is provided between multiple filter plates, and the filter plates and the filter frame are connected by a chain, etc. When the plates are opened, the filter frame is pulled through the chain, and the filter dregs are transferred to the filter plate. (filter cloth on the surface of the filter plate)
When removed from the press, the filter frame tilts and the filter dregs fall off by itself.Compared to the single-type filter press mentioned above, the double-type filter press allows the filter cloth to be stretched on a flat surface. There is an advantage that the load applied to the filter cloth during filtration is small and the filter cloth is less likely to be damaged.
Further, since filter dregs can be easily removed from a flat filter cloth, there is an advantage that the amount of dregs attached is small. For this reason, conventional dual filter presses were not equipped with the above-mentioned automatic cleaning device.
また、複式フイルタープレスに従来の自動洗浄

ルしてもなおもノズルと濾枠とが衝突するおそれ
がありそのことが複式フイルタープレスにおける
洗浄装置の自動化をさまたげていた。 Furthermore, when a conventional automatic cleaning device is installed in a dual filter press, the filter frame becomes an obstacle to the nozzle drooping. In other words, in the case of a double filter press, the gap between the filter plate and the filter frame is narrow when the plate is opened, so even if the nozzle hanging position is accurately controlled, there is still a risk of collision between the nozzle and the filter frame. This was hindering the automation of cleaning equipment in filter presses.
〔考案の目的〕
そこで本考案は複式フイルタープレスにおける

ものである。 In order to achieve the above object, the automatic cleaning device for a filter press of the present invention has a filter frame 3 between each of a plurality of filter plates 1a, 1b, 1c supported in a vertical position.
The filter frames 3a, 3b are pulled by the filter plates 1a, 1b, 1c which move horizontally when the plates are opened, with the filter frames 3a, 3b interposed between them.
In a multiple filter press configured such that the filter dregs are inclined and the filter dregs fall off, a trolley 8 that moves parallel to the plate opening direction is provided above the multiple filter press, and the lower end of the trolley 8 is formed into a triangular sword-like shape. The lifting plates 11, 11 are suspended so as to move up and down, and a roller 19a is installed at the end of the tip-shaped portion of the lifting plates 11, 11 so that the peripheral surface slightly protrudes from both side edges of the lifting plates 11, 11. , 19b, and the nozzle pipes 13a, 13b are attached to the lifting plates 11, 19b.
11, and when the plates are opened, the elevating plates 11, 11 are lowered to connect the front and rear filter plates 1a, 1b, 1c and the filter frames 3a, 3b.
The rollers 19a, 19b are brought into contact with the filter plates to direct the cleaning water to the nozzle pipes 13a, 1.
This is characterized in that the fuel is injected from 3b.

ように取着されている。 The automatic cleaning device installed in this dual filter press is provided with a support rail 7 parallel to the support rail 2 above, and is movable on the support rail 7. That is, a truck 8 is provided so that it can run on support rails with wheels 14, 14, a cylinder 9 is provided vertically on the truck 8, and a support plate 10 is provided horizontally at the tip of the rod of the cylinder 9. Reference numerals 15 and 15 designate hollow guide shafts having one end fixed to the support plate 10 and passing through guide tubes 16 and 16 provided on both sides of the cylinder 9 of the truck 8. Lifting plates 11, 11 each having a triangular shape with a sword-like lower end are vertically fixed to both ends of the support plate 10, and mounting pieces 12, 12 protrude from the inner surface of the lower end of the lifting plates 11, 11. The two nozzle pipes 13a, 13b are installed horizontally between the two elevating plates 11, 11 by fixing U bolts 13, 13 thereto. Here, in order to make the hollow guide shafts 15, 15 also serve as water supply pipes to the nozzle pipes 13a, 13b, hoses 17a are connected to the lower ends of the hollow guide shafts 15, 15 and the water supply ports 14a, 14b of the nozzle pipes 13a, 13b, respectively. , 17b. 2
0, 20... are nozzle tips provided at regular intervals on the side surfaces of the nozzle pipes 13a, 13b. 1
Reference numeral 8 designates an elevating plate whose lower end is shaped like a sword point, similar to the elevating plates 11, 11 which are also fixed to the nozzle pipes 13a, 13b. Moreover, 19a, 19b are rollers rotatably attached to the outer surfaces of the elevating plates 11, 11, and the rollers 19a, 19b are designed such that their peripheral surfaces slightly protrude from both side edges of the elevating plates 11, 11. It is attached.

ならしめる。 In the filter press automatic cleaning device configured in this way, after filter dregs are dropped from between each filter plate, a water receiving pan (not shown) is placed at the bottom of the filter press, and the filter press is again shown in FIG. 1. Filter plate 1
The space between b and 1c is widened, the trolley 8 is stopped above it, and the cylinder 9 is operated to open the nozzle pipes 13a and 13.
Let 3b hang loosely. At this time, washing water is jetted diagonally downward on both sides from the nozzle tips 20, 20 of the nozzle pipes 13a, 13b to shower and wash the filter slag adhering to the filter cloth 4 and the filter frame 3b. In addition, if the inclination of the filter frame 3b is not sufficient or the distance between the filter frame 3b and the filter plate 1c is narrow during the hanging, the elevating plates 11, 11 and the elevating plate 1
The sword-like tip of No. 8 intervenes between the filter frame 3b and the filter plate 1c and widens the gap between them, so the nozzle pipe 1 can be removed without any obstruction.
3a and 13b can be made to hang down. At this time, by adjusting the hanging position to such an extent that the roller 19b touches the filter cloth 4 on the surface of the filter plate 1c, the filter cloth 4
The distance between the surface and the nozzle tips 20, 20, . . . is kept constant.
こうして濾枠３ｂおよび濾板１ｃの洗浄ができ

る。 After the filter frame 3b and filter plate 1c have been washed in this way, the nozzle pipes 13a and 13b are raised, the cart 8 is moved a little and stopped again above between the filter plate 1b and the filter frame 3a, and the cylinder 9 is operated in the same way. The nozzle pipes 13a and 13b are hung down again to wash the filter cloth 4 of the filter plate 1b and the filter frame 3a with a shower.
こうして濾板１ｂ，１ｃ間の洗浄ができたら次

As described above, the automatic cleaning device for a filter press of the present invention is provided with a sword-like lifting plate, and when hanging down, the lifting plate fits between the filter plate and the filter frame to ensure a gap between them. Therefore, even if the nozzle pipe does not collide with the filter frame, or even if the stop position of the truck is slightly shifted, the nozzle pipe can be reliably suspended between the filter plate and the filter frame. When the lifting plate is lowered, the rollers provided on the lifting plate roll in contact with the filter cloth on the surface of the filter plate, so that the lifting plate can be lowered with light friction, and the filter cloth is not damaged. Since the distance between the nozzle tip and the nozzle tip is kept constant, the cleaning water jetted from the nozzle tip can be sprayed onto the entire filter cloth without wasting it and with the necessary and sufficient jetting pressure, ensuring a reliable cleaning performance. can. Therefore, it is advantageous in that it enables automatic cleaning in a dual filter press.
