Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a front screen front and rear reciprocating device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forward and backward reciprocating device for a disposable screen provided in a vibration damper, and more particularly, to a rear surface of a vibration damper, a rake rotates in an endless track by the power of a driving device, By means of the piston reciprocating unit automatically separating the dislocation screen closely adhering to the main screen, it is possible to prevent friction between the rake and the dislocation screen, and a detection sensor is provided on both sides of the frame at the point where the rake is out of the range in which the dislocation screen is operated, And a piston reciprocating unit provided on the screen reciprocating body to allow the potential screen, which has been advancing, to come into close contact with the main screen.

The management of water resources includes livestock as a part of countermeasures to prevent floods caused by floods caused by floods, countermeasures to prevent flooding of agricultural lands, and drainage pumping stations. Especially, The role of the drainage pump in the importance of flood control is very large.

The management of drainage pumping stations is one of the main roles in river management. Drainage pumping stations to use various kinds of water in rivers, coastal areas, waterways, and other natural disasters such as floods are very important. , And the technology is being developed and improved worldwide.

Drainage pumping stations often contain various types of impurities, such as wood, grass, household or agricultural waste, vinyl, etc., which can interfere with the operation of the pump in the drainage pumping station, which must be removed as a harmful component of the drainage pumping station.

In general, a damper is used to remove the impurities. In general, the damper is installed in a low-lying drainage pumping station, a water supply water intake pipe, a related water supply channel, a sewage treatment plant and a dam, It is a device that filters through the screen and then removes the crushing water. Typically, it is distinguished as a hydraulic crusher and a rotary crusher.

The hydraulic damper has little trouble and can be easily repaired and replaced in case of failure. In the case of a rotary damper, it can be operated in conjunction with a pump and can be continuously treated with a plurality of rakes.

However, as the water intake and drainage pumping stations become larger and the capacity of water intake and drainage becomes larger, the hydraulic damper can not easily handle various inflowing contaminants, and when the amount of inflow of contaminants is large, Rotary dust collectors are widely used to automatically remove dust and dirt from the pump front suction area of the pump or drain pump.

Here, in order to examine the details of the rotary damper, as disclosed in the patent registration No. 10-1177922 of the present applicant, a frame installed on both side walls of a water channel, a guide rail provided inside the frame, A main screen installed between the rails and adapted to filter out water discharged along with the water stream, a plurality of electric potential screens installed at a lower front end of the main screen for filtering the water droplets passing between the main screen and the bottom surface of the water channel, An apron for guiding rearward the raked rake so that the rake is drained, and an apron for collecting the raw material, an endless rim for continuously rotating the rake, Chain, a rotating shaft of a sprocket which rotates in conjunction with the above-mentioned and without chain A rotary jejingi consisting of a conveyor for transporting away the collected water jingae rearward of the driving motor and the apron to transmit the driving force in one direction.

According to the above-described structure, the water droplets which are floated and floated together with the water stream pass through the main screen together with the water and the water droplets larger than the main screen diaphragm interval are filtered on the main screen. Also, when the sprocket rotates by the operation of the drive motor, the endless chain coupled to the sprocket is rotated to rotate, and the rake coupled to the endless chain is rotated.

Therefore, the rake passing between the main screen diaphragms starts to remove from the front screen screen and the main screen screen, and then removes all of the main screen screen, and then moves along the apron, And discharges the discharged water to the outside.

However, in order to prevent interference with the rotation radius of the rake, a spacing space is formed between the damper and the bottom surface, and a dislocation screen for blocking passage of the dripping material into the space is integrally fixed to the front lower portion of the main screen .

Therefore, if the space between the dislocation screen and the main screen is maintained even after rake is collected between the dislocation screen and the main screen, the orifice phenomenon occurs due to the pressure of the water flow, and the flow rate is rapidly increased, It has the drawback of passing all the jiggles.

As a result, failure to properly remove the main damages of the damper can lead to serious problems that have a great influence on the damper disposed after the damper.

Accordingly, the applicant of the present invention has proposed a method for solving the above-mentioned problems. As disclosed in the recent patent application No. 10-2014-0033613, a floor frame, which is connected and fixed between two frames, The fixing bracket provided at the front end of the bottom frame has stopper means for preventing the front surface of the dislocation screen from being tilted so that the front surface of the dislocation screen rotated by the pivot pin comes into contact with the main screen, The back rest of the screen bar is provided with a restoration means for restoring the dislocation screen to the original position when the raking rake is in contact with the rake lak after the disengagement screen is separated from the backrest when the rake lak is not contacted therewith, And a case is provided in the case, Wherein a compression spring is embedded and the rod is in close contact with an end of the compression spring and is coupled to the screen bar, and a case is provided on the bottom frame, and the pull- And a rod which is in close contact with an end of the tension spring and is coupled with a front surface of the screen bar is installed outside the case.

With such a structure, the water droplets floating in the floating water together with the water flow are smaller than the distance between the screen bars of the main screen, Screen.

When the driving device of the vibration damper is operated in this state, the raising and lowering rake fixed to the endless chain is rotated while the endless chain is driven along the guide rails provided inside the frames on both sides by the operation of the driving device.

When the rake rake is not in contact with the electric potential screen even during the rake rake rotation as described above, the electric potential screen is kept in a state of being in intimate contact with the main screen by the reciprocating return means, do.

Then, when the rake rake comes into contact with the dislocation screen, the rake rake forcibly pushes the dislocation screen, which causes the rod coupled to the back of the screen bar to retract the compression spring.

Therefore, the dislocation screen rotates rearward about the axis pin to be separated from the rake rake, while the rake rake collects both the dislocation screen and the dust collected on the main screen.

On the other hand, the action of the main screen, which is passed in accordance with the size of the float which floats and floats together with the water flow, before the operation of the draw-out spring constituted by another embodiment, The rotation is the same as the above-mentioned contents and is omitted.

When the rake rake is not in contact with the electric potential screen even in the course of the rake rake being rotated, the electric potential screen maintains a state of being in intimate contact with the main screen by the reciprocating return means, Do.

Therefore, as the rake rake comes into contact with the dislocation screen, the rake rake forcibly pushes the dislocation screen, which causes the tension spring to be pulled while the rod coupled to the front of the screen bar moves together.

Thus, the dislocation screen is rotated backward around the axis pin, and the rake rake collects both the dislocation screen and the main body captured on the main screen.

As described above, since there is no space between the dislocation screen and the main screen, it is possible to prevent the dust collected at the bottom of the dust collector from passing through the dust collector.

However, since the rake rake comes into contact with the electric potential screen and pushes the electric potential screen, the friction becomes inevitable so that the damaged rake and the electric potential screen are not damaged but the damaged surface must be repaired or replaced with a new one There is a problem.

In addition, since the rake rake is in contact with the electric potential screen and pushes the electric potential screen, the elasticity of the compression spring and the tension spring must be overcome, so that an overload is generated in the driving apparatus for driving the rake rake.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a vibration damper, And a sensor is provided on both sides of the frame at a point where the rake is out of the range in which the potential screen is operative, so that the rake is passed therethrough The potential reciprocating unit is brought into close contact with the main screen by the piston reciprocating unit provided in the reciprocating body of the screen.
