Abstract

PURPOSE:To regenerate completely and automatically filter cloth by providing an endless filter cloth to cover the filtering and concentrating surface of a filter plate, and travelling the filter cloth when the cake is scraped. CONSTITUTION:While supplying the original liquid such as sewage sludge into a tank 1, the original liquid is filtered on the front and rear sides of filter plates 2 by operating a siphon tube, and the filtrate is taken out from the tank 1 through the siphon tube. When a filter cloth 3 covering the filtering surface of the filter plates 2 is clogged, the water level in the tank is elevated. The elevated level is detected, and a driving roll 9 is rotated to travel the filter cloth 3. The deposited cake is scraped off by scrapers 14, and the filter cloth 3 is washed in a washing tank 11 to be regenerated. Thus the filtration (concentration) can be carried out again.

キは、スクリューコンベア２０で取出される。Since the invention requires the above-mentioned configuration, the siphon pipe 15 is operated while supplying the undiluted solution such as sewage sludge to the pot 1, and the undiluted solution is supplied to the 11C or The tP liquid is extracted from the siphon tube 1bK, and the sludge in the 4'Ml is condensed and accumulated in the lower part of the shield 1.At the same time, the tP liquid is extracted from the siphon tube 1bK and the sludge is condensed and accumulated in the lower part of the shield 1. Concentrated sludge (cake) will gradually accumulate on the surface of the cloth.In other words, the IP solution can be taken out at the same time as the stock solution is supplied, and the stock solution can be continuously concentrated. By arranging a large number of filters in parallel, combined with the large filtration (concentration) area, this results in inefficient concentration.Continuing the concentration process described above, When one unit is clogged, the discharge meter of liquid J decreases and the water level in tank 1 becomes iv6, but in this case, this water level is detected and the drive roll 9 is rotated. The adhering cake is peeled off by the scraper 14 by running the r door m3, and the cake is removed by washing in the washing board 10.
It is possible to make Th3 active again, and it is possible to perform filtration again. 1, Ri',, 21J Suinona 19 for VC/Dosujunmen selection is interlocked with Kaimagaku 17 and undiluted solution lJ (Narrow VC installed/Ko 19 (1 small, iυφ) When the liquid gap H of 4'll becomes high, the above-mentioned valve is closed, and the driving roll is rotated to travel δ on the 0-column 3. In other words, the twiphone is Li1J is applied, and the P cloth 3 is run with no water pressure applied to it, and the adhered cake is peeled off with the scraper 14, and at the same time, the clogged material is removed in the cleaning tank 11Vζ. De sarumono deroro. Like this I/
C, 2 Toyama 3 completes the cycle and the cake is separated and washed, then 1? jM u g? Although the IP nja 11± raw operation is not shown in the diagram, it is automatically performed within the time set by a timer. t:, h, In Fig. 2,
The air vent valve 18 installed at the top of the siphon #15 is used once when the siphon is started, and the trap 16 installed at the bottom prevents air from entering when the P liquid decreases. This is to prevent the siphon from being cut. The concentrated cake accumulated in the nozzle section of the machine 41111 is taken out by the screw conveyor 20.
