Embodiment Construction

[0017] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0018] refer to Figure 1 to Figure 3 As shown, a high continuity filter device for treating metallurgical wastewater, including:

[0019] A closed treatment tank 1, the inner cavity of the treatment tank 1 is approximately oval cylindrical, and a water inlet channel 11 is provided on one side of the tank wall of the treatment tank 1, which is used to transport the waste water to be treated into the treatment tank;

[0020] The inner wall surface of the tank wall opposite to the water inlet channel 11 is a screen surface 13 with a plurality of water outlet micropores 12;

[0021] In the tank wall corresponding to the position of the screen surface 13, a plurality of water outlet channels 14 communicating w...

Abstract

The invention relates to the field of environmental protection, in particular to a high-continuity filtering device for treating metallurgical wastewater, which comprises a closed treatment tank and a rotary water pressing piece arranged in the treatment tank. The inner cavity of the treatment tank is in the shape of an approximately elliptical cylinder, the rotary water pressing piece is provided with three arc-shaped surfaces, a sealing scraping piece is arranged at the connecting position of every two surfaces, and when the rotary water pressing piece rotates in the treatment tank, the three sealing scraping pieces are always attached to the inner wall of the treatment tank in a sealed mode, so that the inner cavity space of the treatment tank is always divided into three relatively independent parts. The structure is simple, the wastewater is continuously injected into the treatment tank through the water inlet channel, the rotary water pressing piece can continuously and continuously perform pressure filtration on the wastewater, and scrapes and collects the filtered solid particles, and all the treatment links of the whole process do not generate intermittence so as to substantially improve the wastewater treatment efficiency.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a high-continuity filter device for treating metallurgical wastewater. Background technique [0002] A large amount of wastewater discharged during the metallurgical process mainly includes cooling water, pickling wastewater, dust removal and gas, flue gas washing wastewater, slag washing wastewater, and wastewater condensed, separated or overflowed from the production process, etc. These wastewaters contain a large amount of Suspended metals, solid particles, and dissolved chemical reagents and emulsified oil, etc., will definitely cause serious damage to the natural environment if they are discharged without treatment. The advanced treatment of metallurgical wastewater must first filter the suspended metals and solid particles. [0003] Metallurgical wastewater filtration equipment in the prior art usually first fills a sedimentation tank with wastewater, and ...
