Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to an apparatus for moving filter cloths of a filter press dehydrator, and more particularly, to a filter cloth dehydrator which is capable of moving a filter cloth upward and downward by combining a pinion gear and a rope with an east part and a wire rope, The filter cloth can be easily lifted and lowered even when only a small driving force is added to the filter cloth moving device of the filter press dehydrator.

In general, a filter press is a device for filtering slurry contained in a liquid when processing wastewater in steel making, dyeing, fiber, pigment, smelting, and water and sewage facilities, and then removing moisture and drying to treat the filter. The filter press, which removes water by squeezing solids after solid-liquid separation, is used in all industries including food / chemical engineering / civil engineering / construction / environment.

In addition, as the dumping and landfilling of sludge in the wastewater treatment process became impossible, solid-liquid separation and dehydration directly affect the operation cost of the wastewater treatment plant.

The filter press is connected to both sides of a chain engaged with a chain gear and repeatedly lifted and lowered to press the sludge which is hung by the plurality of filter cloths. The conventional device for moving the filter press filter cloth is shown in Fig. 1 A bevel gear 1 which is engaged with a drive shaft formed elongated in a long shape and a chain gear 2 which is located at one side of the bevel gear 1, And a filter cloth 4 to which one end and the other end are connected and fixed to both sides of the chain 3. The bevel gear 1 and the chain gear 2, A plurality of filter cloths 4 are constituted by a plurality of filter cloths 3.

In addition, a lower portion of the filter cloths 4 is provided with a plurality of lower rollers 5 wound around the lower ends of the filter cloths 4 to guide the filter cloths 4 thereunder.

When the sludge 6 is adsorbed and accumulated between the filter fabric 4 and the filter cloth 4, the filter belt moving device of the conventional filter press constructed as described above drives a plurality of bevel gears 1 engaged with the drive shaft while the drive shaft is driven The chain gear 2 connected to the bevel gear 1 and the chain 3 and the chain 3 engaged with the bevel gear 1 and the chain gear 2 are operated to connect the filter cloth 4) is lowered.

When the filter cloth 4 is lowered as described above, the sludge 6 which has been pressed and caked between the filter cloths 4 is separated from the filter cloth 4 through the lower roller 5, and the caked sludge is separated from the filter cloth 4, the driving shaft rotates in the reverse direction, and the lowered filter cloth 4 is lifted up again, and the sludge is again adsorbed.

In the conventional filter press filter cloth moving device, since the filter cloths are connected to each other by the chain and descend or are moved up and down in the reverse order when the waste water etc. is processed, The chain is broken or the chain is disengaged from the chain gear, thereby causing a problem.

Furthermore, when the chain is detached from the chain gear, the filter cloth connected to both sides of the chain is also disengaged and the lower roller supporting the lower end of the filter cloth is also damaged.
