Description

Washing water filtration device {WASH WATER FILTER APPARATUS}

The present invention relates to a washing water filtration device, and more particularly, to a washing water filtration device configured to recycle the separated water separated from the sludge and the filtration belt of the belt press when the sludge is dewatered. will be.

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 wash water washed with the filter belt of the belt press can be recycled. It is to provide a washing water filtration device.

A sludge chamber in which sludge collected through the sludge discharge pipe of the cylinder is collected is partitioned by a partition wall, and a storage cylinder is disposed, and a discharge tube is connected to the collecting chamber and the sludge chamber of the storage cylinder, and in front of the filter cloth of the filter cylinder. Air injection means for injecting air into the filter cloth and water to the filter cloth The water injection means is provided, the predetermined portion of the filter cylinder is provided with a washing water filtration device characterized in that the water level detection sensor for controlling the opening and closing of the solenoid valve by detecting the water level of the sludge solution flowing into the filter cylinder is installed. do.
