般に製作費が高価となる雌点がある。``Intermediate Points to be Solved by the Invention'' However, in the vacuum suction device as in Japanese Patent Publication No. 46-29419, the suction force is only about 0.6 or higher, and high filterability cannot be expected. In addition, a filter press such as the one disclosed in Japanese Patent Publication No. 52-6903 can pressurize the stock solution sealed in a sealed chamber to a pressure of 10 m or more using a diaphragm, etc., so it has high filtration performance, but it is a batch operation and is continuous. Filter press type filtration machines are inferior in efficiency and difficult to use in processes and the like.Furthermore, filter press type filtration machines are generally expensive to manufacture.

である。The device according to the present invention is configured as described above, and when the stock solution is supplied from the trough 19 onto the filter cloth 1 while running the filter cloth 1 and the vacuum suction box 2, the stock solution is first transferred to the vacuum suction box. filtered by 2. At the same time, the pressure plate 8 also advances forward, and its tip advances below the pressure roller 1).
This pressurizes the furnace slag below. That is, the furnace slag that has been filtered by the vacuum suction box 2 and has lost its fluidity is pressurized by the wedge-shaped pressurizing part of the pressurizing plate 8 as the filter cloth 1 moves forward, and the liquid is further removed. During this pressurization, in this invention, the furnace slag from which υ liquid has been removed by vacuum suction is gradually pressurized, so that continuous filtration can be performed without dispersing the furnace slag. It is possible.

く、円滑に復帰させることができるものである。In this way, when the vacuum suction filtration and pressure filtration are completed, the trough 3 provided in the lower part of the vacuum suction box 2 and the pressure plate 8 is returned to its original position by the cylinder 6. At this time, in the present invention, by moving the support frame 12 upward with the jack 15, the front end of the pressure plate 8 moves upward in conjunction with this movement.
This allows for smooth return to operation without interference between the furnace slag on the following filter cloth and the pressure plate 8.

的となり設置面積を縮少し得る。The p-liquid filtered as described above can be taken out from the vacuum suction box 2 and the trough 3 through the sinterable tube 7, and the vacuum suction box 2 is divided into several chambers in a rotating manner. If it is kept in place, even if the furnace slag that has been vacuum suction-filtered is washed on the filter cloth, it is also possible to take out the cleaning furnace liquid separately. Further, as shown in FIG. 2, if a vacuum suction drum 22 is provided in the vacuum filtration section, the machine body becomes three-dimensional and the installation area can be reduced.

なるものである。"Effects of the Invention" As is clear from the above explanation, this invention adds a function similar to pressure filtration to vacuum filtration, but this pressurizing device is made of a steel-like material with a plate body. This pressurizes the pressurized section of the press, making it possible to continuously filter furnace slag, which has conventionally been difficult to filter under pressure due to its fluidity. Compared to conventional equipment, it can be easily used in processes, etc., and the benefits to industry are significant.
