Description

Elevating filtering device for water treatment facilities {FLOATING TYPE FILTERING APPARATUS FOR WATER TREATMENT REACTOR}

The present invention relates to a filtering device for a water treatment facility, wherein an annular lower frame 10 is attached to a bottom plate 91 of a treatment tank, and an annular upper frame 20 connected to a floating body 50 is connected to the lower frame 10 It is installed on the upper part, and between the upper frame 20 and the lower frame 10, a mesh 30 knitted in a cylindrical shape is installed.

In various water treatment facilities, such as sewage treatment facilities, wastewater treatment facilities, advanced treatment facilities, and non-point pollution treatment facilities, pipes that suction or transfer treated water in a vertical direction are configured. It is common to install a filtering means for filtering various drifts or impurities contained therein, and related prior art includes Patent No. 1283317.

Pipes for vertical transport of such water treatment facilities may have horizontal sections formed at some parts such as the inlet of the pipe or the connection between the pipes, but the overall transport direction is vertical or close to vertical, and the treated water is moved in the direction of gravity or against gravity. It can be said to be a pipe that transports upward, and a submersible pump is installed at the inlet of the double upper pipe, and the above patent No. 1283317 can also be referred to as a filtering device installed around the submersible pump.

Regardless of the configuration of the submersible pump, the filtering device installed at the inlet of the vertical pipe described above must be configured in a cylindrical shape surrounding the inlet of the pipe, which causes various problems.

A flat grid or perforated plate is mainly applied to the filtration screen installed in a general horizontal pipe or oil and inlet, so it is easy to backwash or remove deposited foreign substances, as well as to attach and detach the filtering body. On the other hand, conventional vertical pipe inlet filtration devices, including Patent No. 1283317, are difficult to backwash or remove foreign substances, and access to the submersible pump is inevitably limited when a submersible pump is installed inside the filtration device, There was no choice but to have serious difficulties in the maintenance of the entire facility.

Even in Patent No. 1283317, which is a conventional filtering device installed around the submersible pump, it is necessary to lift the entire filtering device during maintenance and repair work on the submersible pump, and therefore, not only must a complicated lifting structure be prepared, but also safety accidents during work. and the risk of damage to facilities was inevitable.

In particular, such a conventional vertical pipe inlet filter device has a fixed shape and cannot but seriously encroach on the internal space of the storage tank, which inevitably causes considerable inconvenience in the entry and exit of workers.

The present invention was devised in view of the above problems, and in a filtering device for water treatment facilities, an annular lower frame 10 is attached to the bottom plate 91 of a treatment tank, and an annular upper frame to which a floating body 50 is connected to the outer edge. (20) is installed above the lower frame 10, and between the upper frame 20 and the lower frame 10, a net body 30 knitted in a cylindrical shape is installed, so that the water level in the treatment tank rises and the floating body 50 and Water treatment characterized in that when the upper frame 20 rises, the net 30 is deployed upward, and when the water level in the treatment tank decreases and the floating body 50 and the upper frame 20 descend, the net 30 is folded downward It is a lifting type filtering device for facilities.

In addition, in the present invention, a plurality of vertical induction rods 11 are installed on the upper surface of the lower frame 10, and a plurality of activity holes 26 are formed in the upper frame 20, so that the induction rods 11 are active. In a state coupled to the rod, it is an elevating filter device for water treatment facilities, characterized in that the vertical elevation of the upper frame 20 is induced by the induction rod 11.

Through the present invention, without a separate lifting facility, the filtering device installed at the vertical pipe inlet of the water treatment facility can be automatically raised and lowered according to the water level, so that the vertical pipe inlet such as a submersible pump is completely exposed to the outside at normal times, making it easy When the treated water flows into the treatment tank and the water level rises, the filtering device is raised and deployed to block the inflow of flotsam, floating matter or impurities in the treated water into the pipe.

In particular, even when the inflow flow rate of the water treatment facility is congested, such as the flood season, the automatic deployment of the filtering device is possible without direct access by a manager, so that safety as well as convenience in management work can be secured. Accordingly, it is possible to minimize the erosion of the inner space of the treatment tank, so that the convenience and efficiency of management work for other facilities as well as the pipe inlet can be secured.
