On the other hand, Figure 14 shows another embodiment of the third rotating means according to the present invention.

Referring to the drawings, the third rotation means 335 is installed on the main screen 100 or the guide frame 11 so as to be spaced apart from the third guide member 311 by a predetermined distance and is driven to contact with the rear projection 31b. The rake unit 30 is rotated in contact with the drum 61 to rotate the rake retainer 30 by 270 degrees when the slider 47 of the chase follower 71 is separated from the auxiliary guide rail 46. For this purpose, the pinion 337 installed in the housing 33 includes a rack 336 installed in the frame or guide frame 11 of the vibration damper and engaged with the pinion 337. In this case, the pinion 337 has a fan-shaped shape so that the pinion 337 can be separated from the rack 336 at the time when the rotation of the rake unit 30 is completed.

The fourth pivoting means 340 rotates the rake unit 30 by about 90 degrees while the rakes 31 of the rake unit 30 are lowered while removing foreign substances on the main screen 100, thereby causing the rake 31 to rotate. In order to maintain the posture to take out the sloppy material piggybacked on the water, one embodiment is shown in FIG. This fourth rotating means is substantially the same as in the above embodiment.

Referring to the drawings, the housing 33 installed on the support shaft 32 can be rotated in a state where the fourth posture holding member 322 is separated from the fourth guide member 321 at the bottom of the main screen 100. A curved guide member 72 is provided to guide the following member 71 installed in the housing, and guide rollers (not shown) may be installed on the curved guide member 72.

Is preferably installed to be guided along the curved surface (72a) of the curved guide member 72.

On the other hand, the front surface of the lower main screen 100, that is, the front of the fourth rotating means 340 may be further provided with the contaminant inflow preventing means (80).

Referring to the operation of another mechanical vibration suppressor for sewage and wastewater 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. In this state, as the driving unit 25 is driven, the lifting unit 20 is driven to raise the rake unit 30.

In this process, by entering the inlet of the sewage treatment plant or drainage treatment plant, the contaminants located in front of the main screen 100 is placed on the rakes 31 of the rake unit 30 to rise, the rake unit 30 Since the state is supported by the third posture maintaining means 310 is raised to the state that the rake 31 is level. That is, the third posture holding member 312 installed in the housing 33 is in contact with the third guide member 311, and reverse rotation is prevented by the ratchet of the reverse rotation preventing means at the point, and the first auxiliary posture Even if the contaminant is placed on the rake 31 by the retaining means 45, the rake 31 of the rake unit 30 can be prevented from being rotated without maintaining the posture in which the rake 31 can be damped.

 As shown in FIG. 13, when the rake unit 30 approaches the driving drum 60, the third posture retaining member 312 is lifted in the state in which the contaminants are supported by the rake unit 30 as described above. In addition to being separated from the guide member 311, the rear projection 31b is caught by the drive drum 61 and rotated about the support shaft 32, so that the pincers caught on the rake 31 are discharged through the drive drum 61. Is transferred to 400.

In this state, the rake unit 30 is further raised by the conveying means 20, and the slider 47 installed at the end of the following member 71 is guided by the rotation guide members 331 and 332. It rotates about 270 degrees.

In this state, when the rake unit 30 is lowered by the lifting means, the fourth posture holding member 322 is engaged with the fourth guide member 321 so that the fourth guide member 321 holds the fourth posture holding. Moving along the member 322 causes the rake 31 to descend with the rake 31 positioned between the strips of the main screen.

Thus, the rake 31 is lowered while raising or removing the debris caught on the screen.

When the fifth posture maintaining means 325 is provided in the descending process, as shown in FIG. 12, the fourth posture maintaining member 322 is separated from the fourth guide member 321 and the fifth guide member 326. ) And the fifth posture holding member 327 are coupled along the main screen 100 to rotate the rake unit 30 from which the debris is removed and rotated clockwise by a predetermined angle to separate the debris from the main screen 100. .

The descending rake unit 30 is rotated while the following member 72 installed in the housing 33 is moved along the curved guide member 72 to raise the miscellaneous material located on the front of the main screen 100. . At this time, the reverse rotation is prevented by the rotation preventing means, the rake 31 is rotated to maintain a horizontal state and at the same time the third posture holding member 312 is transferred along the third guide member 311.

Therefore, foreign matters attached to the main screen 100 are damped when the rake 31 is raised, and when the rakes 31 are lowered, some foreign substances attached to the main screen are pulled down and some are floated to inflow water into the main screen. You can do it smoothly.

The anti-fog inflow prevention plate 82 of the anti-fog inflow prevention means 80 prevents the inflow of contaminants to the lower end side of the first and second screws on which the rake unit 30 rotates, and prevents the inflow of foreign matters when the rake housing 33 rotates. Interference can be excluded.
