[0018] Example 1 like Figure 1-6As shown, a composite filter cloth filter press includes a support mounting plate 1, a filter press chamber 2, a sludge discharge pipe 3, a feed pipe 4, a collection box 5, a dual-shaft motor 6, a connecting belt 7, a pulley 8, a drainage rotating column 9, a transmission gear 13, a transmission gear 2 14, an actuator motor 15, a water outlet 16, a filter pipe 17, a pulley 2 18, a feed rotating shaft 19, a feed screw 20, a drainage screw 21, a drive rotating column 22, a drive roller 23, a filter cloth 24, a tensioning roller 25, a driven shaft 26, a driven roller 27, a filter belt 28, and filter holes 29. The support mounting plate 1 is fixedly installed on the filter press chamber 2. A feed pipe 4 is fixedly installed at one end of the filter press chamber 2, and a sludge discharge pipe 3 for sludge discharge is fixedly installed at the other end of the filter press chamber 2.

The adjusting pressure block 36 is fixedly mounted on the lower end of the lifting frame 10. The adjusting pressure block 36 is slidably mounted on the inner sliding column 37, which is fixedly mounted on the filter press 2. The tensioning slide plate 38 is slidably mounted on the inner sliding column 37. An adjusting pressure spring 39 is provided between the tensioning slide plate 38 and the adjusting pressure block 36. A tension roller 40 is rotatably mounted on the 8. Under the action of the adjusting spring 39, the tension roller 40 presses the filter cloth 24 and the filter belt 28 downward to achieve sludge filtration. With this setup, when the lifting cylinder 11 is activated, the lifting cylinder 11 drives the lifting frame 10 to move up and down through the output shaft.
