Further, the intermediate conduit 5 normally has the same path as the filtrate header.
Furthermore, the sleeve type structure comprises a two-end sleeved type structure and a single-side sleeved type structure, and the flange type structure is a two-side flange type structure; the two ends of the two-end sleeved type rubber expansion joint are both pipe hoops 4; the unilateral sleeved type is characterized in that one end of the two ends of the rubber expansion joint 3 is provided with a connecting flange 2, and the other end is provided with a pipe hoop 4; the flanges on the two sides are specifically the connecting flanges 2 at the two ends of the rubber expansion joint 3.
Further, when a sleeve type structure is adopted, the length of the rubber expansion joint 3 sleeved into the filtrate main pipe and the middle pipeline 5 is 50-100 mm, and 1-4 pipe hoops 4 are used for ensuring the air tightness of the sleeved section; when the flange type structure is adopted, a loop type connecting flange is selected and used, and the air tightness of the connecting end face of the connecting flange is ensured.
