[0001] ROTARY TYPE DUST REMOVING MACHINE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary damper, and more particularly, to a rotary damper capable of preventing a breakdown of a rotary damper, preventing operation of a rotary damper, and simplifying operation and maintenance, .

Generally, the term "vibration damper" refers to a damper installed in a low-lying low-waterfall drainage pumping station, a water supply water intake system, an irrigation water supply system, a sewage treatment plant, and a dam so as to screen the flooded impurities with the water flow and then remove the impurities Is used.

Generally, such a damper has been developed in various forms such as a rotary type using a chain drive or a type using a cylinder, and a rotary type in which a rake is operated using a chain is used as a typical form.

The rotary damper consists of a main screen for screening impurities and a dislocation screen installed at the front of the main screen for screening the contaminants passing between the main screen and the floor and a scraper for removing contaminants from the screen.

However, the dislocation screen used in the conventional damper has a shape that is set in a substantially vertical direction with respect to the bottom of the water channel, and when the level of the water flowing in at the time of starting operation of the damper or the drainage is lowered, It is impossible to move the grinding wheel by obstructing the flow of the water, and when a piece of wood, plastic, or clogs is caught or accumulated between the dislocation screens, a large load is applied during the rake operation and the driving device is damaged due to warping or overloading And it was difficult to remove the contaminants due to the increase of the water level when the contaminants trapped on the electric potential screen were not removed.

In addition, since it is difficult to drain the pest by the height of the dislocation screen, it is difficult to clean the pest and the pest of the pest caused by the accumulation of water in the pond, and the operation management must be separately performed.

Thus, for example, in the "rotary type vibration damper" disclosed in Patent Document 1, an auxiliary rake is provided on a dislocation screen, and the dislocation screen is rotated so as to raise dirt through the auxiliary rake.

However, in the case of the related art such as Patent Document 1, a separate driving device for rotating the dislocation screen is required, which increases installation and maintenance costs.

Fig. 2 is an enlarged view showing an essential part of the rotary damper shown in Fig.
FIGS. 3 to 5 are explanatory views showing the state of use of the rotary damper according to the embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the drawings. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

FIG. 1 is a schematic view showing the overall configuration of a rotary damper according to an embodiment of the present invention, and FIG. 2 is an enlarged view showing a main part of the rotary damper shown in FIG.

1 and 2, a rotary damper according to an embodiment of the present invention includes a screen unit 100, a chain unit 200, a rake unit 300, and a potential screen unit 400 .

The screen unit 100 is installed at an inclination with respect to the bottom of the water channel 500, and is a component for passing water and filtering out contaminants. At this time, the size of the lattice shape of the screen unit 100 can be applied differently depending on the size of the obstacle.

The chain part 200 is a component that is installed on the screen part 100 and is rotated in an endless track. To this end, a rotary gear is installed at both ends of the screen part 100 at every turn of the chain part 200 And is easily rotatable inside the screen portion. A drive unit including a drive motor and the like for rotating the chain unit 200 and a power transmission unit for transmitting the drive force from the drive unit to the chain unit 200, for example, a chain, a belt, a gear, or the like can be used.

The rake portion 300 is a component that is installed so that a plurality of the rake portions 300 are separated from each other in the chain portion 200 and transports the contaminants caught on the front side of the screen portion 100 to be discharged. The rake portion 300 includes a portion to be mounted on the chain portion 200, that is, a moving cam 310 and a rake member 320 that substantially removes the obstacles hung on the screen portion 100, The forward / rearward moving means 410 described below is operated forward / backward in contact with the moving cam 310 of the rake portion 300. At this time, depending on the circumstances, the back and forth moving means 410 may be operated in contact with the rake member 320 or in contact with both the moving cam 310 and the rake member 320. The plurality of rake portions 300 may not be constrained to each other so that the distance between the adjacent rake portions 300 may be adjusted according to the size of the obstacles or when the specific rake portion 300 is broken or deformed, It is desirable to be able to replace them so as to reduce the maintenance cost. Particularly, the rake unit 300 used in the present invention is preferably arranged at intervals such that the discrete screen units 400 described below can be continuously operated. The scoops 300 are lifted by a separate storage box, for example, a bucket, and the scoops 300 are lifted up by the scoops 300, And moves to the lower side beyond the rear side of the screen unit 100 according to the driving. At this time, a separate cleaning unit (not shown) for guiding the contaminants to the bucket and spraying high pressure air or water to the rake unit 300 is installed so that the rake unit 300 is always clean 100 so as to increase the efficiency of the rotary damper.

The dislocation screen unit 400 is a characteristic element of the present invention and basically blocks obstacles flowing into the space between the floor of the water channel 500 and the lower part of the screen unit 100, Into the turning radius region. Accordingly, it is possible to prevent the obstacles from being caught in the dislocation screen unit 400, thereby preventing malfunction of the rotary damper and simplifying operation and maintenance.

The dislocation screen unit 400 used in the present invention includes a back-and-forth moving means 410 and a link means 420.

The back and forth moving means 410 is disposed at the step 510 formed on the water channel 500 so as to have a floor higher than the floor on which the screen unit 100 is installed, to be. To this end, the front and rear moving means 410 is provided with a wheel 412 so as to enable forward and backward movement, and guide grooves 414 are formed along the direction in which the wheels 412 are moved back and forth by one or both sides. A stopper 512 fitted in the guide groove 414 is provided in the step 510 so as to limit the moving direction and the moving distance of the back and forth moving means 410.

The link means 420 is a component that is pivotally mounted on the pair of forward and backward moving means 410 so that a pair, i.e., the first link 422 and the second link 424 are mutually spaced upward and downward. The first link 422 is located near the bottom side where the screen unit 100 is installed on the lower side, that is, about the forward / backward moving means 410. The first link 422 includes a rake unit 300 The back and forth moving means 410 is operated to move away from the screen unit 100. The second link 424 is located on the upper side of the screen unit 100, that is, on the back side of the screen unit 100, that is, When the touch panel 300 is touched, the front and rear moving means 410 are operated to approach the screen unit 100.

The first link 422 and the second link 424 are composed of two bars fixed to each other. One of the two bars is pivotally connected to the back-and-forth moving means 410 so as to be rotatable Bars 422a and 424a and the other one is gradually widened from the ends of the pivoting bars 422a and 424a so as to form an angle with the pivoting bars 422a and 424a, And the drive bars 422b and 424b are in contact with the rake portions 300 that are in contact with each other. The pivoting bars 422a and 424a and the driving bars 422b and 424b constituting the first link 422 and the second link 424 are fixed to the wall of the water channel 500 in a state of being rotatable using the hinge. . In this case, elongated holes H are formed in the pivoting bars 422a and 424a at the end of the pivoting bar 422a and 424a and the pivoting bars 422a and 424a, The rotational movement of the first link 422 and the second link 424 by the moving cam 310 of the rake unit 300 is changed into a linear movement so that the forward and backward moving means 410 can be moved forward and backward . The angle between the pivoting bars 422a and 424a and the driving bars 422b and 424b may be an acute angle so that the forward and backward moving means 410 can be moved forward and backward smoothly. As described above, in the present invention, the dislocation screen unit 400 is horizontally moved so as to be close to or away from the screen unit 100, thereby preventing the contaminants from being caught in the dislocation screen unit 400.

Hereinafter, a rotary damper according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 3 to 5 are explanatory views showing the state of use of the rotary damper according to the embodiment of the present invention. 3 to 5 are omitted or simplified in order to facilitate understanding of the present invention.

First, when a contaminant is filtered on the front side of the screen unit 100, a driving unit such as a driving motor is driven, and the driving force is transmitted to the chain unit 200 to be driven in an endless track, Is also moved.

3, the rake unit 300, particularly the moving cam 310, which is turned from the rear side to the front side of the screen unit 100 and moves from the lower side to the upper side of the screen unit 100, A force is applied to the drive bar 422b by the force of the rake portion 300 moving.

This force is transmitted to the back-and-forth moving means 410 via the pivot bar 422a which is fixedly arranged to form an angle with the driving bar 422b and the shape of the pivot bar 422a, that is, with the driving bar 422b The rotary motion of the first link 422 is changed into a rectilinear motion by the elongated hole H of the pivot bar 422a so that the forward and backward moving means 410 is operated to move away from the screen unit 100. [

Thus, the contaminants are prevented from entering the space between the floor of the water channel 500 and the screen unit 100 by the potential screen unit 400 located close to the screen unit 100, And then the front and rear moving means 410 are transferred to and discharged from the rake unit 300 passing through the space formed by the falling of the screen unit 100 from the screen unit 100. Particularly, the distal end of the back and forth moving means 410 is formed so that the portion of the distal end moving means 410 facing the rake portion 300 moving upward from the lower side of the screen portion 100 is inclined so that the rake portion 300 is separated from the screen portion 100 So that it can be moved as close as possible to the operated back and forth moving means 410. That is, it is possible to reduce the possibility that the back and forth moving means 410 is separated from the screen unit 100 and a space is formed through which the contaminants can escape.

As shown in FIG. 5, the rake unit 300, which is operated to move the front and rear moving means 410 away from the screen unit 100, continues to move upward in the screen unit 100 as shown in FIG. And contacts the drive bar 424b of the link 424. Similarly, the force by which the rake section 300 moves is transmitted in the order of the pivot bar 424a and the back and forth moving means 410. In the case of the second link 424, in contrast to the first link 422, 410 are close to the screen unit 100.

That is, each of the plurality of the rake portions 300 contacts the pair of link means 420, in other words, the first link 422 and the second link 424, (100), and then operates to move closer to the screen unit (100).

The spacing between the plurality of the rake portions 300 is set such that the distance between the first and second rake portions 300 and 422 is such that the one rake portion 300 passes the second link 424, So that the back and forth moving means 410 can move forward and backward repeatedly to prevent the obstacles from escaping between the potential screen portion 400 and the screen portion 100 as much as possible.

In the meantime, although the step 510 in which the dislocation screen unit 400 is installed in the present invention is shown as being almost perpendicular to the drawing, it may be formed at various angles such as an acute angle or an obtuse angle depending on the use environment.

Although the forward / backward movement means 410 is illustrated as being operated substantially parallel to the floor of the waterway 500 in the drawing, it may be operated to have some degree of angle if necessary, Can be used in a completely fixed state in the state of being close to the screen unit 100 without moving. In this case, the link means 420 is omitted and not used.

In the present invention, the forward and backward moving means 410 is moved back and forth in contact with the first link 422 and the second link 424 in accordance with the movement of the rake portion 300. However, (Not shown) may be used together, or the back-and-forth moving means 410 may be moved back and forth only by hydraulic or pneumatic devices.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

It is therefore to be understood that the embodiments described above are to be considered in all respects as illustrative and not restrictive and the scope of the invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
