Description

Scum / Sculpture Removal Device {An apparatus for removing scum}

The present invention relates to a device for removing scum and contaminants generated at the upper part of sedimentation basins and condensate tanks, such as water purification plants and wastewater, sewage and manure treatment plants, and collecting and lifting the upper scum of each sedimentation basin and thickener tanks. The present invention relates to a scum / scavenger removal device that can comprehensively process a series of processes to be transported out of a furnace.

In general, scum and contaminants are generated in the sedimentation basin and the concentration tank while treating the incoming influent in water treatment plants, sewage and wastewater treatment plants, sewage and manure treatment plants. The scum and contaminants thus generated flow into the treated water and are discharged unless they are removed from the sedimentation basin and thickener. Therefore, sedimentation basins and thickening tanks must be removed from time to time when scum and contaminants are generated. For this reason, the sedimentation basin and the concentration tank of the above treatment facility are equipped with equipment to remove scum and contaminants. Conventional scum and scum removal equipment consists of pipes connected to scum eliminators installed on top of sedimentation basins and thickening tanks, or scum boxes for temporarily storing scums and contaminants transported. It consists of a jib hoist that lifts and stores in a container. When the scum and contaminant removal process using this equipment will be described in more detail, first, scum and contaminants generated in the sedimentation basin and thickening tank are removed by the scum eliminator. Then, the scum is transported through a pipe or waterway and collected in a scum box composed of a mesh screen. At this time, when a certain amount of scum is collected in the scum box, the scum box is lifted with a jib hoist, stored in an export container, and then taken out.

Since such a conventional processing apparatus is configured by combining a plurality of separate apparatuses, the installation and control thereof are complicated, and the scum collection function of the scum box is inferior. In particular, since the scum box is placed on the floor, it prevents dehydration of scum and scum, as well as corrupts the scum and scum collected, causing odor and causing pests. In addition, since dehydration does not work properly, the working conditions are poor due to the dropping of contaminants and leachate when lifting the scum box, and the method of transferring the scum box to an over-the-counter carrying container is to turn the box upside down or attach a hinge to the lower part. I'm using the method of dropping by temporarily releasing it, so both methods are very hard, dangerous and messy. Thus, lifting the scum box and carrying it to the container is very dangerous and difficult, and there is a high risk of safety accident. In addition, in the scum box made of mesh, scum and contaminants do not fall well, but do not fall completely, so that the screen function is deteriorated and the appearance is not good.

As such, the existing scum and the scum removal device are composed of a plurality of separate facilities, which makes the installation complicated and difficult. In particular, since the workforce is assigned to individual facilities, automation is difficult and maintenance is difficult.

Accordingly, an object of the present invention is to solve the above-mentioned drawbacks, and to simplify the configuration by comprehensively processing a series of processes of collecting and lifting the scum generated in the sedimentation basin and thickening tank and transported to the export container. The aim is to provide a scum / anti-fog removal device that can simplify and enhance the work efficiency as well as realize automation.
