[0034] Figure 4 and Figure 5It is a main part front view and side view of the suspension apparatus 100 of the filter cloth which concerns on 1st Embodiment of this invention. Long holes 22, 22 are opened in the up and down direction on the lower brackets 6, 6 hanging down to the lower parts of both ends of the filter plate 2, and a pair of return rollers 7, 7 are slidably supported and erected on the left and right sides. In the slotted holes 22,22 of the lower brackets 6,6. The return roller 7 is composed of a floating roller 23 and a rotating roller 24. The floating roller 23 is supported and erected in the long hole 22 of the lower bracket 6. The rotating roller 24 is sleeved on the outside of the floating roller 23 and the filter cloth 11 is hung around it. The return roller 7 makes both ends of the floating roller 23 protrude from the end of the rotating roller 24 and is covered with a sliding sleeve 25 on the outside, and passes through the long hole 22 supported on t...

[0037] Figure 6 and Figure 7 It is a side view and a partial longitudinal front view of 100 A of suspension apparatuses for the filter cloth which concerns on 2nd Embodiment of this invention. The dancer roller 23 is fitted with the rotating roller 24 constituting the return roller 7 so that both ends of the dancer roller 23 protrude from the elongated hole 22 of the lower bracket 6 and pinion gears 28, 28 are fitted therein. Racks 29 and 29 are arranged along the long hole 22 of the lower bracket 6 , and the pinions 28 at both ends of the dancer roller 23 mesh with the rack 29 .

[0038] When the filter cloth 11 is immersed in the stock solution and shrinks, if the filter cloth 11 wound on the rotating roller 24 shrinks irregularly and one end of the floating roller 23 rises, the floating roller 23 is inserted into the floating roller 23 The pinion 28 on the other end rotates by meshing with the rack 29, and the pinion 28 meshing with the rack at the other end also rotate...

Abstract

The filter cloth-expanding devices (100, 100A) in a filter press (200) wherein pairs of filter cloths (11, 11), the upper edges of which are joined, are expanded between filter plates (2, 2) that are open- and closeably disposed to face each other are provided with hollow rotating rolls (24) that are provided below the filter plate (2) and around which the lower ends of the filter cloths (11) are wound, floating rolls (23) that are rotatably disposed in the hollow interiors of the rotating rolls (24), and a pair of lower brackets (6, 6) that extend down from the lower parts of both edges of the filter plates (2). The paired lower brackets (6, 6) have elongated holes (22, 22) that are formed in the vertical direction and hold both ends of the floating rolls (23) therein.

Description

technical field [0001] The present invention relates to a free-running filter cloth suspension device of a filter press for treating upper water sludge, sewage sludge, industrial wastewater sludge, etc., and a filter press with the filter cloth suspension device. Background technique [0002] Conventionally, in the case of filter presses that process large-capacity sludge, in order to shorten the time of the filtration cycle, although the filter cloth suspended between the filter plates is moved to shorten the discharge time of the filter cake, if the The new filter cloth suspended between the filter plates is dipped into the stock solution, and the filter cloth gradually shrinks. [0003] As a suspension device for freely lifting the filter cloth that adjusts the expansion and contraction of the filter cloth, for example, there is a suspension device for the filter cloth proposed in Patent Document 1. The driving belt is connected, the lower end of the filter cloth is enga...
