The invention relates to the field of filtration, in particular to an anti-clogging rotary filter device for metallurgical wastewater. Including a fixed cylinder, a drainage cylinder and a filter cylinder; the fixed cylinder is sealed and installed on the sewage pipe and has a water injection port at the upper end of the interior, the filter cylinder is set inside the water injection port and the water injection port forms a water cavity, the drainage cylinder is set in the fixed cylinder and the lower end is connected with the fixed The cylinder is connected, the upper end is connected with the filter cylinder, the drain cylinder, the water injection port and the fixed cylinder form a water storage cavity; the filter cylinder includes several filter plates, and the end and tail of the filter plates are slided and inserted to enclose a circle, and the vertical end of the filter plate is provided with a brush rod 1. The other end is provided with an adapter rod, and the upper end of the fixed cylinder is provided with adjustment rails for guiding the movement of the adapter rod at intervals. In the present invention, through the mutual cooperation between the adapter rod and the adjustment rail, the filter cartridge forms a movement cycle of contraction and expansion under the pressure of the waste water, and the relative movement of the brush rod and the filter screen during the circulation process. Self-cleaning automatically to prevent clogging.
Description
Technical field [0001] The present invention relates to the field of separation filtration, specifically to a metallurgical wastewater anti-clogging rotary filtration device. Background [0002] Metallurgy refers to the process and process of extracting metals or metal compounds from minerals and using various processing methods to make metals into metal materials with certain properties. Metallurgical technologies mainly include pyrometallurgy, hydrometallurgy and electrometallurgy. Metallurgical production process will produce a large amount of wastewater, wastewater will inevitably contain certain metal impurities, so in the treatment of metallurgical wastewater usually need to filter it, filtered can not only reduce the burden of subsequent wastewater treatment, but also can be filtered out of the metal impurities reuse. In the filtration process, most of the existing filtration facilities can not automatically clean the filter plate, which is very easy to cause the filter pl...
