Description

Washing water purification device {WASH WATER FILTER APPARATUS}

The present invention relates to a washing water purifying apparatus, and more particularly, to separate the water separated from the sludge by the filter cloth of the belt place and the impurities contained in the washing water to wash the filter belt of the belt press can be filtered and reprocessed. And it also relates to a washing water purification device configured to be passed through the filter cloth and purified water is returned and recycled.

In general, the process of dewatering the sludge solution by using a belt press is an appropriate concentration for the sludge solution containing the sludge in the particulate state introduced into the mixing tank 20 through the sludge inlet pipe 21 as shown in FIG. Sludge in the state of particulates contained in the sludge solution is changed to a gel state that is easy to dehydrate as the liquid polymer having a polymer state, that is, a coagulant is added, and then the sludge containing the sludge changed to the gel state. The solution flows into the storage box 11 of the belt press 10 through the guide tube 22.

Then, the sludge in the gel state contained in the sludge solution introduced into the storage box 11 is pulled up by the filter belt 12a which makes the bottom surface of the storage box 11 inclined, followed by the upper filter belt 12b. The water is dehydrated by being squeezed by a plurality of pressing rollers 13 and is converted into a sludge cake in a semi-solid state, and then removed from the filter belts 12a and 12b by the top plate 14 and then to the conveying belt 15. The water of the sludge solution, which is transported by the gas and collected in the cyclone 16 and introduced into the storage box 11, is discharged through the filter belt 12a.

After the sludge cake is separated from the filter belt (12a) (12b) washing water is sprayed at a predetermined pressure from the washing water spray nozzles (17a) (17b) to remove the sludge cake that was not removed from the filter belt (12a) (12b) The filter belts (12a) (12b) can be passed through the water of the sludge solution introduced into the storage box 11 more easily, thereby separating from the sludge solution by the filter belts (12a) (12b) The separated water and the washing water washing the filter belt (12a) (12b) is collected in the collecting plate (18) located in the lower portion of the belt press (10).

Then, the separated water and the washing water collected in the collecting plate 18 are sent to the storage tank through the discharge pipe 19 or discharged to the outside.

However, the process of dewatering the sludge solution using the belt press 10 is a valuable resource because the separated water or washing water collected in the collecting plate 18 is discharged to the outside or sent to the storage tank to be discharged to the outside. The vast amount of separated and washed water is not recycled and wasted, as well as there is a problem that can destroy the natural environment when the separated or washed water collected in the collecting plate 18 is directly discharged into the river or sea.

The present invention has been proposed in view of the problems described above, and its purpose is to dehydrate the sludge with a belt press so that the separated water separated from the sludge and the cleaning water washed with the filter belt of the belt press can be purified and recycled. It is to provide a washing water purification device.
