The present invention relates to a drum filter device that can remove the sludge of the waste water generated during the water treatment operation of the furnace, in particular, in a drum method, and more specifically, to collect the sludge inside the drum rotational operation. The present invention relates to a drum filter device for sludge removal of wastewater, which allows the filter member of the drum to be mounted very easily, and at the same time, replaces only the damaged part of the filter, thereby reducing the maintenance and maintenance cost of the drum filter device.

In general, oil-based waste water is essential in the steel process, especially in the furnace water treatment operation. Such waste water is separated into oil and water to proceed with waste water treatment, that is, sulfuric acid is added to the oil-containing waste water transferred from the organic material collection tank. The oily liquid is added to break up and separated, and then a flocculant is added to generate high particle sludge, and such sludge is caked to remove it.

Therefore, a conventional drum filter device for removing such wastewater sludge is schematically illustrated in FIGS. 1 to 4.

That is, as shown in Figures 1 to 4, the porous bar 116 is formed on the surface via a bearing block as a rotary bar 114 connected to the drive motor 112 to the upper side of the reservoir 100 in which the wastewater inlet is installed. The drum 110 is installed to rotate, and is integrally coupled to the outer circumferential surface of the drum 110, and a plurality of through holes 122 are formed, and a plurality of protrusions 124 are formed on the bottom of the elastic plate 120 made of plastic. ) Is fixed, and a filter-cloth 130 for filtering sludge into the drum outside the elastic plate 120 is mounted as a wire 140 and a fixing band 150 in the drum longitudinal and transverse directions. It consists of the configuration.

That is, in the conventional sludge removal drum filter device having the configuration as described above, when the waste water fills the drum 110 by the pump (not shown) operation of the reservoir 100, the drive motor 112 of the reservoir. The drum 110 is rotated at a constant speed, and at this time, the waste water to be discharged by centrifugal force through the through holes 122 of the pores 116 of the drum 110 and the elastic plate 120 fixed thereon. Sludge is collected in the drum 110 by the filter cross 130, and the sludge filter operation is repeatedly performed to remove the caked sludge through the drum 110, although not shown in the drawing.

However, in the conventional sludge removal drum filter device as described above, first, the filter cross 130 for enabling the filter operation of the sludge is formed integrally with the elastic plate 120 attached to the drum 110. The filter cross 130 is attached to the drum 110 in a fairly cumbersome operation, which is fixed to the outer circumferential surface primarily as a plurality of wires 130 in the transverse direction, and additionally fixed as the fixing band 150 in the longitudinal direction. It is extremely difficult and delayed in installation work.

In addition, since the filter cross 130 is integrally mounted to the drum, even if only a part of the filter cross 130 is damaged during a long time sludge filter operation, the entire filter cross 130 is replaced by the aforementioned troublesome fixing and dismantling operation. And end up wasting money by unnecessary filter replacement.

In addition, due to the fragile structure in which the worker attaches the filter cross 130 to the surface of the drum 110 manually, an unstable sludge filtering operation may be performed, or sludge that is not completely filtered may be inserted into another tube to remove the tube. There were several problems, such as clogging.

The present invention has been made in order to improve the various conventional problems as described above, the object is to install the filter member of the drum to be very easily mounted on the outer surface of the drum so that the removable filter cross for filtering the sludge. To provide a drum filter device for sludge removal of wastewater, which is easily performed as well as disassembly for replacement.
