STACKED-BARREL-TYPE MAGNETIC WASTEWATER SEPARATION AND PURIFICATION DEVICE

摘要

A stacked-barrel-type magnetic wastewater separation and purification device comprising a magnetic absorption separator (3), a drive mechanism, a slag scraping mechanism, a slag discharging mechanism, and a water charging and discharging mechanism. The magnetic absorption separator (3) consists of two or more concentric magnetic barrels (9) having different diameters, wherein each magnetic barrel (9) circumferentially consists of a magnetic absorption area (9.1) provided with a magnet (18) and a non-magnetic slag discharging area (9.2) provided with no magnet (18), and the space between two adjacent magnetic barrels (9) forms a waste water drain (10). The slag scraping mechanism comprises a slag scraping blade (4.1), an overflow-proof sheet (4.2), a drive arm (4), and a drive frame (12); the slag discharging mechanism consists of a slag collector (11), a slag storing chamber (22), and a slag discharging pipe arranged at the bottom of the tank (1), wherein the slag storing chamber (22) is internally provided with an anti-hardening blade (16). The slag scraping blade (4.1) and the overflow-proof sheet (4.2) are arranged in the waste water drain (10) between adjacent magnetic barrels (9). The concentric magnetic barrel structure of the non-magnetic slag discharging area (9.2), combined with the slag scraping mechanism, enables a continuous operation of the magnet (18) in full immersion. The slag absorption ability of the magnet (18) is exploited to their best advantage, and the fluctuations in the density of magnetic suspended substances in the waste water can be addressed by adjusting the number of slag scraping blades (4.1).
