Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

a plate frame filter cloth bag is shown in figures 2 and 3 and comprises a base cloth 1 and a top cloth 2 arranged on the base cloth 1, wherein the base cloth 1 and the top cloth 2 are arranged in the same square shape, and the center positions of the base cloth 1 and the top cloth 2 are fixedly connected together to form a connecting part 3. Still be fixed with reinforcing part 4 between base cloth 1 and the top cloth 2, reinforcing part 4 encircles connecting portion 3 and sets up, and reinforcing part 4 can further strengthen base cloth 1 and top cloth 2's joint strength.

As shown in fig. 2, at least four connecting holes 5 are uniformly distributed on the base fabric 1 along the outer edge line, when the number of the connecting holes 5 is four, the connecting holes 5 are respectively arranged at four corners of the base fabric 1, and the number of the connecting holes 5 is usually a multiple of four. In this embodiment, the number of the connection holes 5 is sixteen. Be provided with on the top cloth 2 and correspond and the same fixed orifices 6 of quantity with connecting hole 5 position, during the in-service use, can also add on connecting hole 5 and the fixed block and establish iron sheet bordure, strengthen the structure of connecting hole 5 and fixed orifices 6. Connecting pieces 7 penetrate through the connecting holes 5 and the fixing holes 6, and the connecting pieces 7 are used for fixing the outer rings of the top cloth 2 and the base cloth 1 together to form a bag shape, so that the top cloth 2 and the base cloth 1 can coat the plate frame filter plate.

As shown in fig. 2 and 5, the connecting member 7 includes a connecting rope 71 simultaneously penetrating through the connecting hole 5 and corresponding to the fixing hole 6, and a fastener 72 fixed at one end of the connecting rope 71, the fastener 72 is provided with a mounting hole 8 for the connecting rope 71 to pass through the end far away from the fastener 72, an adjusting member 9 is further arranged in the fastener 72, and the adjusting member 9 is used for fixing the position of the connecting rope 71 penetrating through the mounting hole 8.

As shown in fig. 4 and 5, a sliding cavity 10 is formed in the clamping piece 72, and the sliding cavity 10 is communicated with the mounting hole 8. The clamping piece 72 is also internally provided with an installation groove 11, and the clamping piece 72 is also provided with a through hole 12 communicated with the installation groove 11. The clamping piece 72 comprises two symmetrically arranged splicing parts 721, the sliding cavity 10, the mounting groove 11 and the through hole 12 are formed by splicing the two splicing parts 721, and the opposite end surfaces of the two splicing parts 721 are respectively provided with an inserted bar 13 and a slot 14 matched with the inserted bar 13. When the two splicing parts 721 are spliced, the insertion rod 13 and the insertion groove 14 are used for fixing, and if necessary, the fixing strength can be further strengthened by glue.

The adjusting part 9 comprises an adjusting block 91 connected in the sliding cavity 10 in a sliding manner and an adjusting spring 92 arranged in the sliding cavity 10 and abutted against the adjusting block 91. The direction of sliding of regulating block 91 is perpendicular to the axial lead direction setting of mounting hole 8, offers the regulation hole 15 that corresponds with mounting hole 8 on the regulating block 91, and adjusting spring 92 sets up in the one end of regulating block 91 direction of sliding, and adjusting spring 92's elasticity makes regulating block 91 remove towards the direction of keeping away from the spring to make regulating hole 15 and mounting hole 8 dislocation.

The clamping piece 72 is further provided with a sliding hole 16 communicated with the sliding cavity 10, the sliding hole 16 is located on one side of the adjusting block 91 departing from the adjusting spring 92, a sliding block 17 is fixed on the adjusting block 91, and the sliding block 17 protrudes out of the clamping piece 72 along the sliding hole 16. When needing to penetrate the mounting hole 8 with connecting rope 71 and fix, make mounting hole 8 and regulation hole 15 align through pressing sliding block 17, then will connect rope 71 and penetrate along mounting hole 8, when penetrating the back that targets in place, let go up sliding block 17, the adjustment block 91 removes towards the one side of keeping away from adjustment spring 92 under adjustment spring 92's effect this moment to make adjustment hole 15 and mounting hole 8 dislocation fix connecting rope 71.
