One end of each of the left brace 41 and the right brace 51 is provided with pivot holes 411 and 511 (refer to the ninth figure). It is pivotally connected to the two support rods 25 of the corresponding plate frame 2, and the spring 27 pushes up on the left support rod 41 and the right support rod 51; A left pivoting member 42 is pivotally connected between to form a left link group 4, and the other ends of the two right support rods 51 of each two adjacent filter cloths 3 are pivotally connected to a right pivoting member 52 to form a right link. Group 5. Please refer to the eighth and tenth figures, the other ends of each of the left support rod 41 and the right support rod 51 are also provided with pivot holes 412, 512, and each of the left pivot member 42 and the right pivot member 52 is set to ∩-shaped rod, the left pivotal member 42 and the right pivotal member 52 are provided with threaded parts 421, 521 on both sides respectively, so as to penetrate downward and pivot on the radially corresponding pivots of the two left support rods 41 and the two right support rods 51 respectively. Contact holes 412, 512. Furthermore, the other end of one of the left brace 41 of each left link group 4 may have a left rod portion 413 extending leftward, and the other end of one of the right brace 51 of each right link group 5 may have The right rod 513 extends to the right.

The two guide rails 6 (refer to the fourth and fifth figures) correspond to two adjacent plate frames There are guide rods 61 slidably straddling between 2 and each guide rod 61 is provided with a guide ring 64 (refer to the tenth figure) on both ends of each guide rod 61, and the two guide rails 6 are each fixedly provided with a guide ring 64 that penetrates forward and backward to guide each corresponding guide ring 64 The steel cable 65 guides each guide rod 61 to move back and forth. A left spring 62 and a right spring 63 are respectively connected to the bottom of the two ends of each guide rod 61, the bottom end of each left spring 62 is connected to the top end of the lower relative left pivot member 42, and the bottom end of each right spring 63 is connected to the lower relative right pivot member 52 top. Furthermore, the two guide rails 6 are pivotally connected to a plurality of guide arms 7 spaced apart from each other under the guide rod 61. Each guide arm 7 is pivotally connected to the opposite support shaft 66 of the guide rail 6 through a through hole. The guide arm 7 is provided with a downward direction. The guide portion 71 extending from the left support rod 41 and the right support rod 51 is provided with a guide edge 711 at the rear edge of the guide portion 71, and the guide arm 7 extends upwardly from a stop portion 72, and the guide rail 6 is provided with a stop guide portion The restricting member 67 that is moved forward and upward in 71 makes the restricting member 67 abut against the rear edge of the stop portion 72.

When the filter press of the present invention drives and controls each plate frame 2 backwards (as shown on the left in the fourth, fifth and eleventh figure), the left rod 413 of the left brace 41 of the plate frame 2 and the right The right rod portion 513 of the support rod 51 pushes the guide portion 71 of the corresponding guide arm 7 to swing backward and upward (refer to the eleventh figure) to allow the plate frame 2 to pass backward, and then the plate frames 2 overlap and lean against each other. Refer to the fourth to seventh diagrams, each frame 2 uses the upper sludge ports 22 and 31 for feeding, so that the high-quality sludge can be quickly squeezed down to fill each filter chamber 21 by weight, saving feeding operations When the sludge is dewatered by squeezing the sludge between the two adjacent filter cloths 3 of each of the two plate frames 2, the two left support rods 41 of each left connecting rod group 4 are arranged in parallel and close to each other, and each right connecting rod group 5 The two right support rods 51 are arranged in parallel and close to each other, and the filter press continues to squeeze and dehydrate the sludge into a mud cake 8 (refer to the fifth figure).
