Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, and in particular to an industrial wastewater desulfurization pretreatment filtration device. Background Technology

[0002] In industrial production, the pretreatment of industrial wastewater, especially desulfurization wastewater, is a crucial step in environmental governance. Desulfurization wastewater contains large amounts of suspended solids, sulfates, heavy metal ions, and other pollutants; direct discharge without effective treatment will severely pollute water bodies and soil. Filtration, as the core process in desulfurization wastewater pretreatment, separates solid impurities from the water, providing qualified water for subsequent advanced treatment and reducing equipment corrosion and processing load. Therefore, developing efficient and stable industrial wastewater desulfurization pretreatment filtration equipment is of significant practical importance for improving desulfurization wastewater treatment efficiency and reducing environmental risks.

[0003] Current industrial wastewater desulfurization pretreatment filtration mostly uses traditional filter press equipment. Its core mechanical structure mainly consists of a fixed frame, filter cloth assembly, hydraulic pressing system, and simple drainage pipeline. The hydraulic system drives the pressing plates to apply pressure to the desulfurization wastewater in the filter chamber, forcing the liquid through the filter cloth into the drainage channel, while solid impurities form a filter cake on the filter cloth surface. After filtration, the filter plates are manually or with a simple robotic arm to open. Some equipment is equipped with a low-frequency vibration device to assist in the removal of the filter cake. The cleaning process typically uses fixed nozzles for localized rinsing.

[0004] However, existing technologies have significant shortcomings in the filter cake cleaning process. Traditional equipment relies mainly on natural falling or low-frequency vibration for filter cake removal. Due to the strong viscosity of solid impurities in desulfurization wastewater, the filter cake easily adheres to the filter cloth surface, resulting in slow removal and large residues. To thoroughly clean the filter cake, frequent shutdowns for manual cleaning are required, which not only prolongs equipment downtime and reduces filtration efficiency but also increases labor costs and operational risks. Therefore, this paper proposes an industrial wastewater desulfurization pretreatment filtration device to address these issues. Utility Model Content

An electrical box 1 is fixedly installed on one side of the frame 5 to control the equipment. An end plate 22 is fixedly installed on the other side of the frame 5 to protect the internal components of the frame 5. The end plate 22 is fixedly connected to the electrical box 1 on both sides of the outer wall of the frame 5 to provide a mounting for the feed pipe 17.

At this time, the pressing plate 16 squeezes towards the center, and the material is compressed and filtered by pressure. The filtered liquid is collected through the discharge branch pipe 9 on the side of the filter plate 6 and discharged through the discharge port 10. After compression, the claw 7 is activated to open the filter plate 6. At the same time, the vibration motor 2 runs.
