Problems solved by technology

A large amount of water is used in the aluminum recycling process, such as cleaning water, cooling water, etc. Since most of the sewage in the aluminum recycling workshop contains various metal elements, it is neither economical nor environmentally friendly to discharge the sewage directly

Embodiment Construction

[0015] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0016] like figure 1 As shown, the present embodiment provides a filtering device, which is arranged in a sump for collecting waste water. The sump includes a water collection area 11 and a filter area 12. The water collection area 11 is connected to an external waste water source. A partition wall 13 is arranged between the water collection area 11 and the filter area 12, and a water gate 14 is provided on the partition wall 13, and the filter device 90 is arranged on the water gate 14 for collecting water. The waste water in zone 11 is pre-filtered.

[0017] like Figure 2-6 As shown, the filtering device 90 includes a flashboard device 91, a lifting device 92, and a filter screen device 93, and the flashboard device 91 includes two door-shaped splint parts 911 mounted on the partition wall, The two splint parts 911 are respectively located ...

Abstract

The invention discloses a filtering device. The filtering device is arranged in a water collecting pond for collecting waste water. The water collecting pond comprises a water collecting area and a filtering area, wherein the water collecting area is connected with an external waste water source; a partition wall is arranged between the water collecting area and the filtering area; the partition wall is provided with a water flow door; the water flow door is provided with a filtering device, and is used for primary filtering the waste water in the water collecting area; the filtering device comprises a plugboard device, a lifting device and a filtering screen device. By adopting the technical scheme, floating objects floating on the water surface can be blocked outside the plugboard device by the filtering device, large-particle sundries entering into an inner side from a gap of the bottom are blocked by a main filtering screen, and are prevented from causing abrasion on equipment after entering into a filter press.

Description

technical field [0001] The invention relates to a filter device, in particular to the technical field of waste recycling. Background technique [0002] At present, the production process of primary aluminum consumes a lot of energy, and whether it is indirect or direct, the emission of greenhouse gases is relatively large. The primary aluminum industry accounts for the largest share of emissions from the non-ferrous metals industry. The energy consumption of primary aluminum in the industrial production process mainly comes from bauxite mining, alumina production, aluminum electrolysis and carbon anode production, among which the aluminum electrolysis process consumes the most energy. Compared with electrolysis in the production of primary aluminum, the utilization cost of recycled aluminum is only 10% of the latter, and in terms of energy consumption, recycled aluminum is only 5% of the former. From the point of view of the production cycle, as long as there are sufficien...
