Filtering and drying apparatus for wastes recycling

Abstract

The present invention relates to a filtering and drying apparatus for slurry and resource recycling. A sludge and resource recycling filtration-drying apparatus is provided to prevent the contamination of the region around the apparatus by the falling of sludge using a cover. A sludge and resource recycling filtration-drying apparatus comprises the following: a treatment tank(10) including a supplying pipe(11), a discharging pipe(12), a detecting sensor, and a rotary shaft; a rotating drum including a treated water containing space; a driving device(30) rotating the rotary shaft; a scraper separating foreign materials from the surface of the rotating drum; a hot air drier(50) supplying hot air to the surface of the rotating drum; a drum washer(60) supplying washing water to the surface of the rotating drum; an aerator supplying air to the bottom of the treatment tank; and a microfiltration device(80) including a treated water outlet(82) and a vacuum pump(84).

Description

Technical field [0001] The present invention relates to a filtration and drying device for reusing mud and resources, which filters waste water and performs drying treatment on the sludge to reuse the reusable mud and resources contained in the waste water. Background technique [0002] Various waste water discharged from industrial equipment and the like contains a large amount of particulate matter. If it is directly discharged in this way, it will pollute the river. Therefore, a removal device for removing particulate matter is installed on the equipment that discharges the waste water. [0003] In the past, most of the removal devices used to remove particulate matter from waste water used a method of squeezing the filter cloth to remove particulate matter filtered in the filter cloth after the waste water was put into the filter cloth. [0004] Due to the particulate matter removal device squeezed by this filter cloth, in the state of filtering a large amount of particulate matt...

AI Technical Summary

Problems solved by technology

[0016] The mud and resource recycling filter drying device of the present invention is proposed to solve the above-mentioned problems in the prior art. A cover is installed on the upper part of the immersed treatment tank to prevent the surrounding pollution caused by the sludge falling to the periphery of the equipment. On the other hand, the hot air drying device is installed so that it is connected to the cover to supply hot air to the surface of the rotating drum at the bottom and rotate While the drum rotates on the water surface of the treatment tank and reaches the stripper, the surface of the rotating drum is heated and dried by hot air. At this time, the sludge adhering to the surface is also heated and dried, making it easy to remove from The surface is detached, and by drying the sludge, the sludge can be reused easily without the need for additional subsequent drying equipment for sludge reuse
