Sludge Removal Device {SLUDGE PURIFICATION APPARATUS}

The present invention relates to a sludge removal apparatus, and more specifically, after removing sludge from the sludge removal means, the sludge is to remove the organic matter by the drum-type microorganism removal means and the disk-rotating microorganism removal means and at the same time to remove the sludge It relates to a removal device.

In general, sludge purification equipment is the first method used to filter green algae and other fine solids from water treatment facilities. Currently, the sludge purification device has been developed a lot and placed at the tip of the treatment facility where sludge occurs continuously, such as fish farms. Used as a device for filtering material.

In the conventional sludge purification apparatus as described above, when sewage is introduced into the housing through an inlet 110 formed at one side of the housing 100, the sewage is a cylindrical purification drum 120. The outer periphery and the curvature of the same as the center of the purification drum or higher, that is, the partition wall 300 is integrally provided in the housing as a gap 200 to form a hemispherical shape and does not cause interference during the rotation of the purification drum 120 The sewage obtained by) flows into the purification drum through one side opening 140 of the purification drum 120.

At this time, the first sprocket 510 is installed on the shaft of the motor 500 and the second sprocket 530 connected to the chain 520 is driven to rotate the rotating shaft 600 to purify the bearings stored in the bearing. The drum 120 is to rotate.

On the other hand, the filtering net of the rotating purification drum 120 is rotated together with the sludge of sewage located inside the rotating filter net, the nozzle pressure of the washing apparatus 700 installed on the outer upper portion of the purification drum 120 The filter net is washed by the sludge is washed and the sludge is dropped into the sludge receiver 800 installed on the inner top of the purified water drum 120 is discharged to the outside by the sludge discharge hole 910 of the fixed shaft 900 through the connecting pipe Sludge is removed is drained through the mesh to the outlet 150.

At this time, a part of the sewage flows into the gap 200 between the purification drum 120 and the partition 300 in the introduced sewage, and there is a problem that sludge is not completely removed. Proposed new model registration No. 271193.

The structure of Utility Model No. 271193 is perpendicular to the inner side of the support frame for supporting the filtering network in which the particles can be filtered to fine sludge in the fixed shaft installed at right angles with the sewage inflow member having the sewage inflow hole for inflowing sewage. Install a plurality of protruding wing pieces at regular intervals and rotate the drum by forcelessly using the introduced sewage as if spinning a watermill, supplying the sewage from the inside of the purification drum to pass through the filtering network to purify the sewage. By removing the sludge by discharging the purified sewage and rotating the purification drum without installing a separate power transmission device, it reduces the installation cost and simplifies the structure and installation of the device when the power unit is not installed. The time is shortened.

However, the sludge is about 80% moisture, about 15% organic matter, and the remainder is composed of inorganic materials, and since most of them exist as solid particles or in the form of crystal water, it is very difficult to lower the moisture content by a mechanical method. In addition, when the sludge is mechanically removed, bubbles are generated, and in addition, microorganism removal means is separately installed and used to decompose and remove organic substances contained in the sewage.

The present invention devised in view of the above problems is to remove the organic matter by the drum-type microbial removal means installed integrally after removing the sludge from the sludge removal means, simplifying the structure, saving installation cost, reduced installation space convenience of use And to provide a sludge removal apparatus to maximize the filtration efficiency.
