Claims

[Claims for Utility Model Registration] (1) A cylindrical filter medium 1; a support member 2 that suspends and supports the cylindrical filter medium 1; Vibration imparting members 8, 12, 13, 14, and 17 that hold the filter medium 1 in an expanded state and apply vibrations to the filter medium 1 during cake discharge, and close the opening at the lower end of the filter medium 1 to form the filter medium 1 into a bag shape. On the other hand, after filtration, a first closing member 3 that releases the blockage of the lower end opening of the filter medium 1 to open the lower end and discharge the cake inside the filter medium; and a stock solution supply member that supplies the stock solution into the filter medium. 33
a second closing member 5 for closing the upper end opening of the filter medium 1; a second closing member drive circuit 48 for driving the second closing member 5; A pressing member 4 that presses the filter medium 1 whose upper and lower end openings are closed by members 3 and 5 to perform squeeze filtration, and a supply state of the stock solution disposed on the pressing member 4 and supplied into the filter medium. A sensor 4 that detects and outputs a signal when a predetermined state is reached.
1, a stock solution supply stop circuit 51 for stopping the stock solution supply member 33 from supplying the stock solution to the filter medium 1; and a stock solution supply stop circuit 51 for driving the stock solution supply stop circuit 51 when receiving the signal output from the sensor 41; The supply of the stock solution by the stock solution supply member 33 is stopped, and the second closing member drive circuit 48 is driven to close the upper end opening of the filter medium 1 with the second closure member 5, while the pressing member 4 and the A filtration device comprising: a control device 46 that drives the vibration imparting members 8, 12, 13, 14, and 17, respectively. (2) The vibration imparting members 8, 12, 13, 14,
17 is a spring 8 and vibration applying cylinders 12, 13, 1
4, 17, the vibration applying cylinders 12, 1
2. The filtering device according to claim 1, wherein the filter medium 1 is vibrated by driving the filters 3, 14, and 17 and the biasing force of the spring 8. (3) The filter medium 1 is a polygonal cylindrical filter medium body 1.
c, the filter medium main body 1c, and the vibration imparting members 8, 1
Connecting member 1a connecting 2, 13, 14, 17
, 1b. 3. The filtration device according to claim 1, further comprising: 1b. (4) The filtration device according to any one of claims 1 to 3, further comprising a stock solution supply member 33 that supplies the stock solution into the filter medium 1 from an opening at the upper end of the filter medium 1 whose lower end is closed. (5) The filtration device according to any one of claims 1 to 4, wherein the sensor 41 is a liquid level detection sensor that detects the liquid level of the stock solution in the filter medium. (6) The filtration device according to any one of claims 1 to 4, wherein the sensor 41 is a temperature detection sensor that detects the temperature of the stock solution in the filter medium. (7) The filtration device according to any one of claims 1 to 4, wherein the sensor 41 is a pH sensor that detects the concentration of hydrogen ions in the stock solution in the filter medium.
