The present invention relates to a mobile moving screen device, and more particularly, to a mobile moving screen device capable of automatically and easily transporting and discharging contaminants in a floating matter treatment process in a water treatment plant.

In general, inflow water from water treatment plants, such as water purification plants, sewage treatment plants, and wastewater treatment plants, contains a large amount of impurities, floating substances, and various contaminants, thereby causing problems such as flooding the waterway or clogging the pump.

A screen device is used to separate these floats from the influent. In such a screen device, the screen is fixed, and when an incoming foreign matter is caught on the screen, it is removed by scraping and lifting using a rake connected to the transport chain.

Due to this, there is a problem in that it is not easy to remove the screen and the contaminants entangled in the screen by the rake, and even if it is removed, it is not sufficiently removed. In addition, when the screen is used for a long time, the water level rises due to clogging of the screen, and there is also a problem in that it is difficult to maintain and manage the screen device. In addition, after performing the work, the operation of the screen device is stopped at a predetermined time, and there is also the inconvenience of the operator having to remove and clean the hanging contaminants.

On the other hand, a moving screen device in which the screen is not fixed is also used. However, such a conventional moving screen device has problems such as being corroded by welding of the screen blades and having to replace the whole even if some are damaged.

In addition, the screens arranged in the transport direction of the chain are provided to be spaced apart from each other, and in the section where the transport direction of the chain is changed, the screens arranged in the longitudinal direction are further widened. There is a problem of falling, which leads to a problem in that the efficiency of water treatment is lowered.
