Description

Foreign object removal device for a vibration damper rake and a vibration damper including the same {Foreign object removal equipment for rake of dust separator and dust separator comprising the same}

The present invention relates to a debris removal device for a vibration damper rake and a dust removal device including the same, and more particularly, is installed in a vibration suppressor for removing sewage contaminants, and effectively separates the contaminants from the rake to collect and transport the contaminants caught on the screen. This prevents contaminants from sticking to the rakes and preventing them from flowing back into the sewage without being separated by their own weight, and preventing the screen or rakes from being damaged due to the load caused by the condensate accumulated and introduced into the sewage again. The present invention relates to a foreign matter removal device for use and a vibration damper including the same.

In general, a vibration damper is a mechanical device that removes suspended matter on a screen installed at a place where floating matter enters, such as a pumping station or a drainage inlet, using power.

Among them, the rotary damper is installed in the inlet of the heavy rain and summer drainage pumping station, power plant, and sewage treatment plant to quickly remove contaminants such as suspended wastes that interfere with the pump operation and discharge. As a mechanical device to secure, such a rotary vibration damper quickly lifts and removes contaminant foreign substances introduced by the rotation of the screen lifting in the inlet and the lifting lifting rake fastened to the swing chain device.

In this way, the screen is equipped with a vibration damper or rotary damper is a device used to filter the contaminants flowing along the inflow channel is provided in the pipeline of the waste water treatment plant, more specifically, the vibration damper and the like is provided with a screen provided therein and It is a treatment device that filters the suspended substances flowing through the inflow channel of the sewage, wastewater relay pumping station and other sewage and wastewater treatment plants using a rotating rake while turning it, and the dust removal device for removing impurities is included in sewage and wastewater. From food waste, plastic bags, rags, plastics, beverage cans, wood, rubber, sand, and other types of debris (called contaminants) can be filtered to ensure the safety of drainage or pumping devices.

In addition, it is possible to smoothly maintain the flow of the channel by filtering out various foreign matters introduced into the inflow channel through the dust removal dust removal device.

Such a vibration suppressor is installed on the screen for filtering the contaminants and the front side thereof so that the rake of the rake means is installed and operated so as to scrape up the contaminants caught on the screen surface and discharge them to the outside through vertical rotation. It is effectively used to prevent the failure or blockage of pumps and other waterways such as wastewater relay pumping stations.

However, the conventional dust collector collects the trapped traps on the rake and freezes the collected traps on the rake after orbital rotation. As it flows in or is continuously stuck to the rake, it reduces the efficiency of removing impurities, and after the rake is collected, the contaminants introduced into the sewage gradually accumulate on the screen, which causes the screen or rake to break due to the load. Will exist.

The foregoing invention refers to the background of the art to which the present invention pertains, and does not mean the prior art.
