The present invention relates to a screen for removing contaminants, and more particularly, by using an automatic position restoration function by a rotation screen, an automatic tension control function of a drive chain, and a selective hinge rotation function of an apparatus main body together with durability of a product. It relates to a rotary automatic screen for removing debris to increase efficiency

Generally, the screen for removing impurities is a kind of suspended solids treatment equipment used for inflow facilities such as sewage and wastewater treatment plants. Such screens are used to catch and remove the impurities contained in the sewage and wastewater, forcibly lifting and removing them. will be.

Therefore, generally, the dust removal device for removing the contaminants, which is generally widely used, has a configuration as shown in FIG.

This is to install a power motor (M) connected to a pair of drive chains 20 connected to the upper end of the mounting frame 10 to the mounting frame 10 of the predetermined length to form an inclined upward, left and right sides. And forming a rectangular grate screen 30 having a plurality of non-bar shaped bars at the inner side of the inner side, and having the rake 40 rotated and guided in one direction at the front surface of the screen 30 again. ;

In addition, the screen having such a configuration was to catch the trapped by the comb-shaped bar, and to scrape out the trapped trapped by the rake taking the rake shape, thus having a series of use relations.

However, the conventional screen for removing the contaminants as described above takes the rounding structure of the screen and the lower part of the installation frame, and forms a spaced space from the bottom surface, so that the contaminants contained in the sewage and wastewater are not filtered. In addition, some of the discharge through the screen and the lower portion of the installation frame, or the structural problem of being stuck in the spaced gaps.

In addition, the screen for removing the contaminants as described above, the one-way rotational conveying action of the rake is made by the drive chain, if the drive chain has a constant use relationship for a certain period of time, the phenomenon that the drive chain is sagging;

Therefore, the above-mentioned conventional screen for removing the contaminants may cause malfunction of the device due to sagging of the drive chain, or even deteriorate the durability and performance of the device, such as the drive chain may be dislodged during operation of the device, thereby making it impossible to remove the contaminants. I had a problem.

Alternatively, such a screen for removing the contaminants is to install a facility for smoothly flowing and discharging sewage (cold matter) to the rear of the sewage pipe in which the screen is installed, that is, an independent type drain pump. For this reason, if deposits such as sand or moss accumulate on the rear surface of the screen due to continuous use for a certain period of time, it should be cleaned periodically;

As described above, the conventional screen for removing the contaminants has a unitary body structure of the screen and the body frame, and has a fixed structure as shown in FIG. 1 inside the sewer pipe;

Therefore, when deposits accumulate on the rear surface of the screen due to continuous use for a certain period of time, it causes a considerable handling problem of forcibly releasing the entire fixed installation of the screen from the installation site. When forced removal of the screen was not possible, the very inefficient use of waste that had to be used without leaving the sediment in the sewer pipe remained.

On the other hand, in recent years to solve some of the problems of the conventional screen for removing the impurities, by installing a potential screen on the lower front of the installation frame to prevent the leakage of some of the contaminants, and adjust the tension of the drive chain by the tension control unit The screen vibration damper has been registered in advance application (Utility Model Registration No. 0247793);

In addition, "front elevation rotary damper" (utility model registration No. 0325084) and "rear drive front elevation rotary damper" (utility model registration No. 0325085) which allow the screen body to be pulled upwards to allow the angle adjustment of the screen. Has been registered in the first application.

However, in the above-mentioned prior art registered, the screen damper first, the structure of the potential screen installed in the lower front of the installation frame is supported by the elastic means, the overall configuration of the front and rear by the rotational force (advancing force) of the rake It takes a form that is rotated at a certain angle, and thus the problem that excessive stress concentration phenomenon occurs in the rake in accordance with the installation structure of the potential screen in which the entire configuration is moved (rotation control) at the same time, and also in the rake In returning the displaced screen moved to its original state by the elastic force means, the reverted dislocation screen collides with the main screen and causes deformation of the apparatus with unnecessary operation noise. It was to give a problem.

In addition, although the screen damper registered in the first application is to partially compensate for the drooping phenomenon of the drive chain by the tension control unit, the configuration of the tension control unit space portion, shaft portion, movable rod, screw rod, spring support, buffer Combining very complex components such as springs, the installation relationship is very difficult, and excessive material costs are consumed.

On the other hand, another pre-registration technology "front rising rotary damper" and "rear drive front rising rotary damper" is provided with a traction device in the front or rear of the damping base body to rotate the damper installed in the sewer pipe at an angle toward the upper direction Although it is designed to be adjusted, the "front rising rotary damper" and "rear drive front rising rotary damper" are provided with supporters on both left and right sides of the vibration suppression body forming an integrated structure, and the support is fixed to the rotating shaft. As a result, the overall configuration of the device (vibrator) was to be controlled to rotate;

Thus, the "front rising rotary damper" and "rear drive front rising rotary damper" of such a configuration is to give a problem that consumes excessive power in accordance with the configuration of the overall configuration of the device, and also, such a high efficiency power source This provided a very non-economic installation problem, such as the use of relatively high horsepower motors and traction wires.

Therefore, the present invention was devised to solve the general problems of the conventional screen vibration damper;

An object of the present invention is to provide a rotary screen forming an individual hinge assembly structure at the upper end of the potential screen, so that the provided rotary screen is automatically returned to its original position by its own weight, thereby unnecessary stress concentration during scraping operation by the rake. It is to provide a rotary automatic screen for removing the contaminants to prevent the phenomenon, and to facilitate the handling and maintenance relationship in the event of an abnormality such as trapping of the contaminants, according to the individual hinge assembly structure of the rotating screen.

In addition, another object of the present invention is to maintain the tension of the drive chain by a chain guide rail having an elastic support function to prevent the sagging of the drive chain without having to obtain a period of use (hours), It is to prevent the closing of the malfunction and the deterioration of the operation efficiency. Also, the automatic tension control function prevents the departure of the driving chain, thereby preventing unnecessary economic loss such as breakage of parts and inoperation. It is to provide a rotary automatic screen for removing debris.

On the other hand, in another object of the present invention, when the central portion of the scree body consisting of the potential screen, the main screen, and the mounting frame can be folded as needed, when the deposit accumulated in the sewer pipe, It is to provide a rotary automatic screen for removing debris that facilitates a series of handling relationships, such as to facilitate the discharge and cleaning (cleaning).

Thus, the specific means of the present invention for achieving the above object;
