In order to counteract this, it is necessary to increase the thickness of the core plate more than necessary to enhance the strength of the filter plate or to arrange a large number of protrusions. When the number of the protrusions increases, the filtration area decreases accordingly, and when the thickness of the core plate increases, the weight of the squeezing filter plate increases. DISCLOSURE OF THE INVENTION The present invention is intended to solve the problems in the above-described conventional squeezing filter plate having a protrusion, and an object of the present invention is to provide a squeezing filter press plate that can safely apply a squeezing pressure. .

The slurry that has been expanded through and is supplied into the filtration chamber 18 is squeezed and dehydrated. The squeeze film surface side peripheral edge 14 of the tubular portion 10 of the squeeze film 3 is compressed into substantially the same plane as the column 12 and the core plate 2
The tubular portion 10 in the through hole 11 is compressed between the through hole 11 and the column 12. Since the core plate 2 receives the above-mentioned compression pressure via the tubular portion 10, no shocking pressure is applied to the core plate 2. Therefore, it is possible to safely apply the filtration compression pressure to the compression filtration plate 1 in the filtration compression step. The space between the squeezing filter plate 1 and the adjacent filter plate 5 is maintained at a predetermined interval by the column 12 as a whole, and cakes having the same water content are obtained in the respective filter chambers 18. Therefore, the core plate 2 is not cracked by the above pressure. In addition, the compressed fluid is the core plate 2
Even if the compressed fluid enters between the through hole 11 and the tubular portion 10, the compressed fluid is received by the cut pocket 20 of the tubular portion 10 and does not flow out to the outside.
