Problems solved by technology

Since the content of Al2O3 in the mold residue is unknown, the amount of NaOH added may be insufficient or excessive, so that there will be NaAlO2 and Al(OH)3 in the system at the same time, resulting in a low Al recovery rate.

Embodiment 2

[0070] Such as figure 1 , 5 As shown, the difference between this embodiment and the above-mentioned embodiments is that a steam recovery cover is arranged above the inner cavity of the heating box 5 . Both the shaking tank 13 and the reaction tank 2 are sandwich structures. A first heat preservation pipe 131 and a second heat preservation pipe 21 are respectively arranged in the interlayer of the oscillation tank 13 and the reaction pool 2 . The first heat preservation pipe 131 and the second heat preservation pipe 21 are respectively wound in the interlayer of the oscillation tank 13 and the reaction pool 2 in a spiral shape from bottom to top. Wherein, the inlet of the first heat preservation pipe 131 communicates with the steam recovery cover through the sixth pipeline 66, and the outlet of the first heat preservation pipe 131 communicates with the second heat preservation pipe 21 through the seventh pipeline (not shown in the figure).

Embodiment 3

[0074] The present invention also discloses a method for aluminum recovery and treatment using the above-mentioned aluminum profile extrusion die cleaning and waste water recovery treatment device, which includes the following steps:

[0075] (1) Place the aluminum profile extrusion die in the storage net cylinder 14, add alkali washing solution in the oscillation tank 13, so that the lower cylinder part of the storage net cylinder 14 is immersed in the alkali washing liquid, and pass through the oscillation tank 13 The heating tube in the boiler heats the alkaline washing solution.

[0076] (2) Drive the first motor 15 to drive the housing net cylinder 14 to rotate, and at the same time push the oscillation tank 13 to swing through the pushing mechanism to carry out alkali cleaning to the mould.

[0077] (3) After alkali washing, open the valve to filter the alkali washing liquid after alkali washing. Wherein the NaAlO2 solution penetrates into the lower chamber through the ...

Abstract

The invention discloses an aluminum profile extrusion die cleaning and waste water recycling device. The device comprises a cleaning tank, a reaction tank, a centrifugal machine, a sedimentation tankand a heating box. Filter felt is arranged in a tank body to divide the tank body into an upper chamber and a lower chamber. A discharging opening of the upper chamber is connected with a first feeding opening of the reaction tank through a first pipeline. A discharging opening of the lower chamber is connected with a feeding opening of the centrifugal machine through a second pipeline. A discharging opening of the reaction tank is connected with the feeding opening of the centrifugal machine through a third pipeline. A light-phase outlet of the centrifugal machine is connected with an inlet of the sedimentation tank through a fourth pipeline. An outlet of the sedimentation tank is connected with a feeding opening of the heating box through a fifth pipeline. The invention further disclosesa method for recycling aluminum through the aluminum profile extrusion die cleaning and waste water recycling device. The device and the method have the beneficial effects that die cleaning is thorough, and the Al recycling rate is high.

Description

technical field [0001] The invention relates to the technical field of aluminum profile forming, in particular to an aluminum profile extruding die cleaning device and a waste water recovery treatment device. Background technique [0002] Aluminum profiles are metal products that use aluminum or its alloys as raw materials and are formed by forging, stamping and other processes. The density of aluminum profiles is generally low, only about 2.7g / cm3. Under most environmental conditions, it can show excellent corrosion resistance. On an equal weight basis, aluminum has nearly twice the electrical conductivity of copper. Aluminum alloy has a high thermal conductivity and is often used to manufacture heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators. [0003] After the aluminum profile is stamped, a certain amount of aluminum-containing residue will remain on the surface of the mold. This residue needs to be remove...
