Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a wastewater treatment device for die-casting machines. Background Art

[0002] The die-casting machine is a machine used for pressure casting, which is mainly used to hydraulically inject molten metal into the mold, and after cooling and solidification, obtain the metal casting of the desired shape. During the production process of the die-casting machine, due to the steps of melting metal materials, heat preservation, cleaning of die-casting molds and cooling of die-casting parts, a large amount of wastewater containing impurities, oxides, oil and other pollutants will be generated.

[0003] At present, the patent number CN208562039U discloses a die-casting machine wastewater treatment device. It includes a solid-liquid separation tank, an oil-liquid separation tank, and a purification tank. The above device treats the wastewater generated in the production process of the die-casting machine in steps. First, the solid particles and other impurities in the wastewater are separated in the solid-liquid separation tank, and the remaining wastewater containing oil is separated in the oil-liquid separation tank. The obtained wastewater without oil is treated in the purification tank and discharged only after the water quality test is qualified. The above device has a reasonable layout, is easy to operate, has a strong degreasing effect, and improves production efficiency.

[0004] But the following problems still exist:

[0005] In the above device, circular magnets are installed in the upper and middle sections of the solid-liquid separation tank, and the waste residue that can be adsorbed in the wastewater is adsorbed by the circular magnets. However, when the inner wall of the circular magnet is full of waste residue and needs to be cleaned, it is inconvenient to clean because the circular magnet is located in the upper and middle sections inside the solid-liquid separator. In addition, the oil content is large, the wastewater is relatively viscous, and it is inconvenient to circulate and is prone to siltation, which has certain limitations.

[0006] To this end, we propose a die-casting machine wastewater treatment device to solve the above problems. Utility Model Content
