Description

An apparatus for with drawing the sludge on a screen}

The present invention relates to a screen vibration damper for sedimentation, and more specifically, a cylinder unit constituting the vibration damper is constituted by a lifting and lifting cylinder to operate a vibration damper arm and a rake arm for scraping the screen, thereby lifting up the debris accumulated on the screen. It relates to a screen vibration damper for the settling paper to enable the operation of the device stable at the time.

In general, the screen damper mounted on the settling paper refers to a device for removing contaminants of the screen mounted on the inlet of the settling paper, and is divided into a mechanical damper and a hydraulic damper. The description of the conventional hydraulic vibration damper is as follows.

4 is a view of a conventional hydraulic vibration damper, a screen 100 mounted on the bottom of a channel of a settlement, a frame 200 installed on an upper side of the screen 100 and including a rail 201, and the rail 201. In the dust removal equipment of the settling paper, consisting of a screen damper (300) mounted on the) and removing the contaminants of the screen 100, and a conveyor (400) for transporting the contaminants lifted from the screen damper (300),

The screen vibration suppressor 300 is mounted to the rail 201 and the main body 301 is fixed to the upper cylinder 302, the upper position of the main body 301 is rotatably mounted and the single cylinder The platform mounting bracket 303 to which the rod of 302 is fixed and the platform mounting bracket 303 are inserted into and lifted up and down by driving the chain 304 and the wire 305, and the rake 307 is mounted on the bottom thereof. It is characterized by consisting of the platform 306.

Therefore, the screen vibration suppressor 300 configured as described above drives the lifting platform 306 mounted on the lifting platform mounting bracket 303 by driving the chain 304 and the wire 305 to lift and remove the impurities remaining on the screen 100. To lift and discharge to the conveyor (400).

However, in the vibration damper configured as described above, since the platform on which the rake is mounted is configured as a single unit, when the platform is lifted when lifting the contaminants, the platform is vibrated severely due to the external factors such as the load of the platform or the wind. In addition, the shape of the contaminants are biased to one side, so that the screen was damaged as well as the vibration suppressor.

In addition, since the metal chain and the wire rope for elevating the platform are easily corroded as they are exposed to the outside, there is a problem that causes the device to fail.

The present invention is designed to solve the above problems, by operating the vibration damper arm and the rake arm scraping the screen by configuring the cylinder unit constituting the vibration damper with the lifting and lifting cylinder, the lifting of the impurities accumulated on the screen It is an object of the present invention to provide a screen damper for sedimentation which can enable the operation of a stable device.

In addition, by mounting the vibration damper arm and the rake arm symmetrically on both sides, and by mounting a rake to lift the screen debris in the lower portion of the rake arm, there is also an object to prevent the lifting of the rake is unbalanced lifting.

Screen damper according to the present invention for achieving the above object, the main body is mounted to the vibration damper arm, the rake arm is mounted to the front of the vibration damper arm and includes a rake, the main body, the vibration damper arm and the rake arm connected to each other It consists of a cylinder unit including a lifting, lifting cylinder to change the angle of the vibration damper arm and the rake arm.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view showing a screen damper of the present invention, Figure 2 is a front view showing a screen damper of the present invention, the first described the configuration as follows.

The screen 1 mounted on the bottom of the channel, the vibration damper support 2 mounted on the upper side of the screen 1, and the rail 21 mounted thereon, and the rail 21 mounted on the rail 21, In the dust removal facility of the settling paper which consists of the screen damper (3) which removes contaminants, and the conveyor (4) which conveys the condensate lifted from the screen damper (3),

The screen vibration damper 3 includes a main body 31 to which the vibration damper arm 32 is mounted, a rake arm 33 mounted to the front of the vibration damper arm 32 and including a rake 332, and the main body ( 31) a cylinder including the lifting and lowering cylinders 342 and 343 so as to connect the damper arm 32 and the rake arm 33 to each other to lift and lower the action of the damper arm 32 and to lift the rake arm 32. It is composed of a unit 34.

And in front of the main body 31 is scraper 35 for scraping the contaminants lifted through the rake 332 to fall to the conveyor (4) is formed to protrude.

This will be described in more detail as follows.

The main body 31 is mounted on the rail 21 so as to be movable to both sides, and a control unit 311 for controlling the cylinder unit 34 is provided.

In addition, the vibration damper arm 32 is coupled to both front sides of the main body 31 via the hinge shaft S1, so that each rotation is possible in front of the main body 31.

In addition, the rake arm 33 is mounted to the front of the vibration damper arm 32 mounted on both sides of the main body 31, the angular rotation bracket 331 is mounted on the upper end of the vibration damper arm 32 and the hinge shaft It is connected rotatably through (S2). And between the lower portion of the rake arm 33 located on both sides is mounted a rake 332 in close contact with the surface of the screen (1).

In addition, the cylinder unit 34 includes a cylinder connecting bracket 341 mounted in the middle of the vibration damper arm 32, a rake between the front of the cylinder connecting bracket 34 and the rear of the angular rotating bracket 331. The lifting and lowering of the damper arm 32 between the lifting cylinder 342 connected through the hinge shaft S3 so as to lift the arm 33, and the rear of the cylinder connecting bracket 341 and the upper side of the main body 31. It is composed of a lifting cylinder 343 connected via a hinge shaft (S4) to enable the operation.

Hereinafter, the operation relationship of the present invention configured as described above are as follows.

As shown in FIG. 3, first, in the initial state, the lifting cylinder 342 is extended and the lifting cylinder 343 remains in a stretched state. In other words, the vibration damper arm 32 and the rake arm 33 are kept folded (see FIG. 3A).

Next, when placing the rake 332 mounted on the lower portion of the rake arm 33 at the lower portion of the screen 1, the lifting cylinder 342 which has been extended is gradually stretched and, on the contrary, the stretched lift By extending the cylinder 343, the vibration damper arm 32 is rotated downward and the rake arm 33 is also lowered. That is, the rake 332 mounted on the lower portion of the rake arm 33 is brought into close contact with the screen 1 (see FIG. 3B).

Next, when the rake 332 mounted on the lower portion of the rake arm 33 is lifted to lift the contaminants caught on the screen 1, the stretchable lifting cylinder 342 is gradually extended, and vice versa. By elastically stretching the elongated lifting cylinder 343, the rake is brought into close contact with the screen 1 to carry out the lifting of the contaminant (see Fig. 3C).

Finally, the lifted contaminants are scraped through the scraper 35 protruding in front of the main body 31 and discharged to the conveyor 4, as shown in FIG. 3a).

On the other hand, the operation as described above is controlled by the control unit 311 mounted on the main body 31 and proceeds repeatedly, it is possible to fully automatic unmanned.

The present invention as described above, by operating the vibration damper through two cylinders interlocked with each other, it is to have the effect of preventing the malfunction of the device at the time of lifting the impurities accumulated on the screen to ensure the stability of the device.

In addition, by firmly fixing the rake to lift the screen of the contaminants, the rake at the time of lifting the contaminants will also have the effect of preventing the screen from being broken.
