Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotary dust separator for removing minor contaminants,

More particularly, the present invention relates to a rotary damper for removing fine contaminants, and more particularly, to a damper for removing dust such as sludge of sewage accumulated in a rake of a damper to accumulate remaining contaminants, And an air discharge portion is provided so as to remove remaining contaminants remaining in the rake downward to thereby reduce the maintenance cost due to breakage of the chain and rake and improve the treatment efficiency of the damper.

As a means for removing dirt such as household garbage that is floated together with overflowing water when the water is flooded at a sewage disposal plant or at a water intake point in a rainy season, various types of damper are selectively installed to drive a rake, Dirt such as various household waste is removed.

An example of such a damper is disclosed in Korean Utility Model Registration No. 1991-4759. The disclosed damper has a structure in which a dawn-removing rake is moved along a screen.

In the case of a conventional rotary damper for dust collecting collectors, a rake provided at regular intervals in a link chain of an infinite track type is circulated, and a plurality of shear rake parts formed on the front side of the rake The dirt is dropped to the lower conveying portion by its own weight and discharged to a separate conveyor or the like in the process of moving up the dirt on the upper portion and riding on the chain wheel on the upper side.

In this case, the link chain that operates the rake of the rotary type vibration damper is circulated by a guide provided in a forward and a posterior direction. That is, when the power of the main motor drives the chain wheel, It moves along a constant trajectory.

When the rake is moved in a state in which the rake is installed at a predetermined interval in the link chain circulated by the guide, the locus of the lower chain wheel is wound on the arc, And is accumulated at a lower portion of the rake out of the trajectory range of the rake and is settled for a long period of time, so that an overload occurs in the upper main motor, which causes damage or breakage of the link chain.

That is, the above-mentioned phenomenon occurs because the trajectory of the rake provided at a predetermined interval in the link chain is arc-shaped, so that dirt such as garbage collects on the bottom surface of the lower chain wheel, and when the operation is continuously repeated, An overload occurs.

As a result, the above-mentioned phenomenon occurs because there is no blocking function for preventing the inflow of dirt to the lower side of the portion corresponding to the turning radius of the rake, so that the link chain is broken or the rake is bent And the like.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a dust collecting apparatus and a dust collecting apparatus, And an air discharging portion for rotating the damper to remove the remaining contaminants remaining in the rake to thereby reduce the maintenance cost due to damage to the chain and rake and to improve the processing efficiency of the damper. The purpose is to provide.

The present invention relates to a fine particle elimination rotary vibration damping device installed in a vibration damping device for removing suspended matters or sludge in a lower portion of a vibration damper and removing residual fine dirt remaining in the rake of the vibration damping device, And an air supply unit for supplying air to the air discharge unit, and a control unit for controlling the rotation unit and the air supply unit, wherein the air discharge unit is provided with an air supply unit for supplying air to the air discharge unit, .

In addition, the air discharge portion is sealed at both ends, and a discharge space is formed in a rectangular tube shape, and a slit portion is provided at one side edge of the air discharge portion, and air is jetted to the rake.

In addition, when the front portion is disposed so as to face the air discharging portion in a state in which the rake connected to the upper portion of the chain is moved up, the control portion drives the rotating portion so that the air is discharged from the air discharging portion Air is sprayed so that the remaining contaminants are removed downward.

In addition, the side plate further includes a sensing unit for transmitting a signal to the control unit. When the front surface of the rake moving along the chain is disposed facing the air discharging unit, the sensing unit transmits the signal to the control unit, Controls the rotary part and the air supply part so that the air is blown onto the rake while rotating the air discharge part.

Further, the damper is further provided with a diagonal air discharge unit for supplying air from the air supply unit to the rake, and the diagonal air discharge unit is supplied with air in a diagonal direction to the rear surface of the rake.
