AI Technical Summary
In existing ethylene glycol wastewater freezing and concentration equipment, the lack of an effective sealing structure between the separation basket and the auxiliary plate leads to waste liquid leakage. Crystals accumulate below the separation basket, resulting in low cleaning efficiency. Furthermore, the gap between the top block and the mesh causes leakage, making it difficult to completely remove the crystals.
The equipment is equipped with sealing components, including a collection basket, a positioning plate, a sealing strip, and a sealing ring. The gaps are sealed by the sealing groove and the sealing ring. Combined with the lifting components and the unblocking components, it ensures that the wastewater does not leak and that the crystals can be completely scraped off.
This method achieves zero leakage during wastewater treatment, with crystals being scraped off above the scraper, avoiding secondary cleaning and improving work efficiency.
