Description

Debris removal apparatus for processing contaminants

The present invention relates to a vibration suppressor, and more particularly, to a dust removal processing device for lifting a rake to lift a contaminant such as sludge and garbage.

In general, the vibration suppressor is installed in a drainage pump station, a water intake station, a related water channel, a sewage treatment plant, and a dam, which is lower than the water surface, to remove foreign substances introduced in a suspended or sedimented state in the water.

These dampers are largely classified into hydraulic dampers and rotary dampers. The hydraulic damper has a structure in which the rake is coupled to a link having a plurality of joints and moved up and down by a hydraulic cylinder to lift the contaminants caught on the screen. In addition, the rotary type vibration damper has a structure in which the rake is coupled to the conveyor chain of the crawler provided on the outer surface of the screen to lift the contaminants.

Korean Unexamined Patent Publication No. 2013-0084525 discloses a method for lifting a dust collector of a vibration damper. The published vibration suppressor is provided with a screen installed to maintain a predetermined angle in the channel so as to separate the contaminants flowing into the channel, and is installed on the base supporting the top of the screen to remove the trapped on the screen, the rake body installed on the upper surface of the base ; A support arm installed to be supported by the rake body; A rake guided to the support arm and movable up and down to lift the debris separated by the screen; Lifting means installed on the rake body to move the support arm up and down; And rotating means installed at an upper end of the support arm to rotate the rake.

And the Republic of Korea Patent Registration No. 10-1378786 is movable mechanical vibration damper, the registered Utility Model No. 20-0338356 is posted mechanical automatic vibration damper. In addition, the Republic of Korea Utility Model Registration No. 20-0262905 discloses a plate moving device of the sedimentation screen screen damper.

Mechanical vibration damper as described above has the advantage that the installation space is narrow, it can be miniaturized, but the structure for lifting and rotating is relatively complicated, and the problem that can not remove the impurities removed by the rake from the screen smoothly from the rake have.

In addition, Korean Patent Registration No. 10-1458768 discloses a water level interlocking type dust collector for early removal of contaminants. The published vibration suppressor is provided at the cylinder stroke end and includes a rake for lifting up the contaminants caught on the screen, and the water level sensor for transmitting a signal to the controller is a contact type sensor installed in a rod type on the side wall of the inflow channel. It is configured to detect the water level by measuring the resistance value affecting the signal to deliver a signal to the controller.

Korean Patent Registration No. 10-1065812 discloses a hydraulic automatic vibration suppressor. The vibration suppressor disclosed is to lift and lower the transfer shaft on which the rake is installed by using a hydraulic cylinder, and includes a transfer roller provided on the circumferential surface of the transfer shaft to improve the bearing force of the transfer shaft against load concentration on one side of the transfer body. .

As the above-described vibration damper uses a hydraulic cylinder as a driving source, the time for removing the impurities from the screen is relatively long, and thus there is a limit to increase the efficiency of removing the dust. Since the control of the vibration damper is not precisely controlled, the separation of contaminants from the rake cannot be made smoothly, and thus the efficiency of the vibration damper cannot be maximized.
