BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bar / wood-and-bar bar screen type vibration suppressor installed in a treatment plant or the like in sewage treatment and river drainage treatment. In particular, the bar screen is constructed by combining adjacent flat steels having different widths and thicknesses. Therefore, the present invention relates to a wood / wooden combined use bar screen type vibration suppressor capable of simultaneously dusting large foreign matters and small foreign matters contained in sewage or drainage with one vibration reducer.

Conventionally, in sewage treatment or sewage treatment in a sewage treatment plant or a river drainage treatment plant, in order to remove foreign substances contained in the sewage or wastewater treated, it is provided to block the flow channel in the treatment tank to trap and remove the foreign substances in the water flow. And a bar screen vibration damper composed of a bar screen for engaging with the bar screen and moving along the bar screen to scrape and discharge the trapped foreign matter.

The bar screen of this bar screen type vibration damper is adjacently installed through a distance piece for fixing a plurality of thin strips of the same size flat steel (flat bar (FB)) at equal intervals, and between the adjacent flat steels. The through bolts are formed so as to be integrally formed, and the front surface of the screen is configured to be the same surface.

However, when one bar screen type vibration suppressor is installed in a sewage treatment plant or a river drainage treatment plant, the scale width of the bar screen is determined according to the size of the foreign matter to be captured and removed. Since a narrow bar screen is adopted, the opening ratio of the bar screen is small, so that the passage loss is increased, and inflow foreign matters that are not captured by the bar screen are mixed with large and small foreign matters. In addition, this large foreign matter may collide with the small bar screen of the body and deform or distort the flat steel (flat bar FB) constituting the bar screen, or damage or render the rake impossible.

For this reason, a wide-scale bar screen is first used to remove large foreign substances in the sewage or drainage so that the foreign substances introduced without mixing the bar screen can be captured and removed even if they are mixed with large and small foreign substances. Two or more kinds of vibration dampers used for removing large foreign substances, and small foreign material dampers using a relatively narrow bar screen for removing small foreign substances are installed in two stages upstream and downstream of the flow channel. .

By removing the large foreign matter in the sewage or wastewater treated in this way, by removing the small foreign matter, it is possible to prevent the large foreign matter and the small foreign matter, in particular, to prevent the overload caused by the large foreign matter caught in the small foreign material dust removal device.

However, since the treatment tank in a small sewage treatment plant or a river drainage treatment plant is small and there is no space for installing two vibration dampers in one treatment tank, it is necessary to newly set a space for installing two vibration dampers in the treatment tank. There was a problem of high equipment costs.

In view of the problems of the conventional bar screen type vibration suppressor, the present invention provides one bar screen type vibration suppressor in a processing tank, whereby a collision force of a large foreign matter even in a bar screen having a narrow scale width and a thin plate thickness can be obtained. It is an object of the present invention to provide a screen / vibrator for both wood-and-wood-bars that is not damaged by damage and can be simultaneously captured and removed from large foreign matters to small foreign matters.

In order to achieve the above object, the bar-type and bar-bar type vibration suppressor of the present invention is constructed by raising and lowering along a bar screen installed in an oil channel, and installing a rake so as to scrape and discharge foreign substances trapped on the bar screen. In the screen type vibration damper, the bar screen is combined so that the width and the plate thickness of the flat steel screen bar are set to a predetermined scale width so as to integrally form the wood bar screen and the fine bar bar screen. It characterized in that the rake is formed by engaging the graduation width of.

In this case, the width and the thickness of the screen bar forming the bar wooden bar screen are larger than the width and the plate thickness of the screen bar forming the wooden bar screen, and the width of the wide bar width of the bar wooden screen One or more plural screen bars can be provided between the screen bars.

In addition, the front end surface of the rough wood screen bar can be provided so that it may protrude in the front position rather than the front end surface of the detail screen bar.

In addition, a rake adapted to move in engagement with the scale width of the bar screen may be configured by combining a combination width rake screen bar with a large scale width bar and a fine size rake screen bar with a fine scale width bar. Can be.

In addition, the tip of the fine-wood rake may be provided to protrude from the tip of the crude wood rake.

In other words, the wood-and-wood combined bar screen type vibration damper of the present invention is moved up and down along the bar screen formed by combining the wood bar screen and the wood bar screen integrally by combining the flat steel screen bars installed in the flow channel, Bar screen type by installing a rake formed by combining the wood rake and the wood rake integrally engaged with the scale width of the wood bar screen and the wood bar screen to scrape and discharge the foreign substances captured by the bar screen. In the vibration damper, the bar screen is made larger in width and plate thickness of the screen bar forming the bark bar screen than the width and plate thickness of the screen bar forming the bark bar screen. Between the screen bars of the scale width, a plurality of screen bars of the fine bar screen is installed, A wood rake formed by arranging the front end face of the clean so as to protrude to a front position than the front end face of the detail bar screen, and forming the rake by installing one steel plate so as to span the width direction of the rake frame. A fine-grained rake formed by installing a thin band-shaped flat bar that can be inserted into the scale width of the fine-grained bar screen at equal intervals so as to be parallel to the fine-grained bar screen. It is characterized in that the tip of the rake is installed so as to protrude from the tip of the timber rake.

In accordance with the present invention, the bar and wood bar screen type vibrator combines different widths and plate thicknesses of flat steel screen bars to have a predetermined scale width to integrally form the bar and bar screens. In addition, by forming a rake by engaging the bar width of the bar screen, it is possible to cope with one damper, to capture and remove inflows from large foreign matters to small foreign matters, and even in a small treatment tank without space for installing two vibration dampers. In addition to the simple installation, it can also be easily compatible with the bar screen type vibration damper of the existing treatment tank.

Further, the width and the thickness of the screen bar forming the bar wooden bar screen are larger than the width and the plate thickness of the screen bar forming the wooden bar screen, and between the wide bar widths of the bar bar screen. By installing one or more screen screen bars at the same time, it is possible to increase the strength of the wood bar screen against large foreign matter in the inflow, and also to set the thickness of the board bar screen thinly. The opening ratio of the bar bar screen can be improved.

In addition, by installing the front surface of the wood screening bar to protrude in front of the front surface of the wood screening bar, large foreign matter as the inflow is first captured on the front surface of the wood screening bar, large foreign material that is inflow to the wood screening bar This collision can be prevented, and thus the screen bar can be prevented from being deformed even if the thickness of the detail screen bar is made to be at least as small as possible, thereby making the passage area of the screen wider.

In addition, by forming a rake to be moved in engagement with the scale width of the bar screen, the combination of the rake wood bar to engage the large bar width screen bar, and the fine rake bar interlocking with the small fine screen bar bar by integrally combining In addition, the load on the rake for washing can be reduced.

Also, by installing the tip of the detail rake to protrude from the tip of the detail rake, it is possible to simultaneously scrape out the large foreign matter captured on the detail bar screen by the movement of the rake and the small foreign matter captured on the detail bar screen. Can be.
