The present invention relates to a vibration suppressor, and more particularly, to a sewage and drainage treatment dust removal device for removing foreign matter such as sludge, contaminants, garbage, and the like contained in the water.

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

An example of such a vibration suppressor is disclosed in Korean Utility Model Publication No. 1991-04759. The disclosed vibration suppressor has a structure in which a claw removal rake is moved along a screen.

In addition, Utility Model Registration No. 0175037 discloses another example of a vibration suppressor. The disclosed vibration suppressor has a screen installed at an inclined angle with a bottom surface, a potential screen for filtering foreign matter passing between the screen bottom surface and installed at the front lower end of the screen, and a screen for removing dust between the screen and the potential screen. A dust removal rake installed at both left and right ends, a drive motor for driving the endless chain such that the rake rotates continuously on the screen, and an upper side of the screen for smooth rotation of the rake rotated by the endless chain and complete removal of the dust. The guide plate is installed in the guide rail is provided on the lower side of both sides of the screen to guide the rotational drive of the endless chain.

Utility Model Registration No. 0323130 includes a pair of frames spaced apart from each other, a screen having a plurality of diaphragms interposed in spaced spaces of the frame to filter dirt moving along with water flow, and at least one area of the rear surface of the screen. It is provided with a damper main body including a coupling piece provided in the.

Also, Utility Model Registration No. 0215622 discloses a hydraulically driven vibration damper, No. 9247793 discloses a screen vibration damper, and No. 0327207 discloses a rotor type vibration damper with an improved ejector.

The vibration dampers configured as described above remove the foreign substances contained in the water while the corrugated rake and the rake rotated by the endless chain are moved between the damping screens, or the eject bar installed to be rotatable has a narrow and long adjustment groove in the driving direction. As it moves along, it removes foreign substances, such as garbage and scum, which are suspended or piggybacked in water.

However, such a conventional vibration damper is provided with a separate screen for removing foreign matters such as garbage, contaminants, etc. from the water, and has a structure in which the rakes are transported between the screens, so that when the foreign matter is caught between the screen and the rakes, smooth driving is performed. There is a problem that this is not done. In particular, since the rakes passing between the screens are simply supported at both ends of the chain, the rakes are deformed when a relatively large load is applied to the rakes.

In addition, the conventional vibration damper is not able to discharge the sediment, such as sediment, sediment, etc. after being transported by water. Therefore, sediment accumulated in the lower part of the damper causes damage to the damper.

Utility Model Registration 0329796 discloses another embodiment of a vibration damper. The disclosed vibration suppressor is provided with a main body having a predetermined angle with respect to the flow direction of the fluid, first and second sprockets installed at both end sides of the main body, and rotationally driven by a driving means, and provided at both sides of the main body, , The first and second chain parts are rotated in conjunction with the second sprocket, and a plurality of wedge bars rotated by the first and second chain parts. Such a vibration damper cannot smoothly remove foreign substances when the angle of the main body approaches vertical. That is, the structure has a structure for recovering the foreign matter by a plurality of wedge bars, but when the inclination of the main body is increased, the friction force between the wedge bar and the foreign matter becomes relatively small, it is difficult to recover the foreign matter.

The present invention is to solve the problems as described above, it is possible to stably remove a large amount of scum, rubbish, grass or wood transported by piggybacking in water, sewage and drainage that can relatively increase the removal efficiency Its purpose is to provide a treatment damper.

Another object of the present invention is to provide a vibration isolator for sewage and drainage treatment that can increase the degree of freedom for the installation site by increasing the installation angle.

Referring to the operation of the vibration damper for the lower and drainage treatment according to the present invention configured as described above are as follows.

First, the vibration damper according to the present invention is installed at an inlet of a sewage treatment plant or a wastewater treatment plant at a predetermined angle. At this time, it is preferable that the take-out protrusion 35c of the rake 35 forms a predetermined angle with respect to the water surface. At this time, it is natural that the floated or trapped water should be installed to pass between the rakes 35 of the take-out means 30 of the vibration damper and between the screen plates 45 of the screen forming means 40. .

In this state, the drive unit 29 is driven. In this way, the spouts 23 and 24 provided on the drive shaft and the driven shaft allow the takeout means 30 and the screen forming means 40 to run on the same orbit as the trajectory of the chain by the chains 27 and 28. Will move to draw.

In this process, the water flowing into the inlet of the sewage treatment plant or the wastewater treatment plant is separated between the screen plates 45 of the screen forming unit 40 and by the second spacers 46 at predetermined intervals. ) Will pass through. At this time, the floating material or foreign matter piggybacked on the water is filtered by the screen plate 45 and the rakes 35 spaced at a predetermined interval, and the filtered foreign matters are caught by the blowout protrusions 35c of the rakes 35. Separated from water.

The foreign matter separated as described above rises by continuously moving the rakes 35 of the take-out means 30, and descends by the own weight at the time of exiting the sprocket on the driving side located at the upper side, and flows into the chute 55. The foreign matter not separated from the rakes 35 is separated by the disk 52 or the scraper of the foreign matter separating means passing between the rakes 35 and flows into the chute 55.

As described above, the brackets 31, 32, 41, and 42 are moved along the edges of the sub-frames 11 and 12 in the process of discharging the foreign matter to partition the ejection space. That is, since the brackets installed on the chains 27 and 28 protrude to a predetermined height, foreign matters supported by the rake 35 may be prevented from falling to both sides.

In addition, since the bucket 75 for discharging the earth and sand is installed inside the chain on the caterpillar, the sediment such as sand, sand, etc. moved to the chain on the caterpillar can be discharged by piggybacking on the transport force of water. At this time, the sediment separated from the basket 75 is discharged to the chute 55 through the rake 35 or the screen plate 45 after being separated from the basket 75 at the time of taking out.

As described above, the vibrator separates the foreign matter from the water by the screen forming means and the rakes, and discharges the separated foreign matter into the chute, thereby increasing the extraction efficiency of the foreign matter from the water.

 As described above, the vibration suppressor for sewage and drainage treatment according to the present invention has the following effects.

first; Since the rake has a structure fixed by the first and second support shafts, foreign matters can be prevented from escaping from the ejection protrusion of the rake and the constraint on the installation angle of the vibration damper can be reduced.

second; The suspended solids or contaminants of the water are taken out while being continuously filtered by the screen plates and between the rakes which are the taking-out means, thereby increasing the take-out efficiency of the foreign matter.

third; The structure is simple and the degree of freedom for installation is increased.

fourth; Since the foreign material is taken out while lifting the foreign material in a direction perpendicular to the transport direction of the water, it is possible to reduce the detachment of the foreign material from the rake.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
