Description

Technical Field

[0001] This utility model relates to the technical field of leather wastewater treatment equipment, and in particular to a leather tanning wastewater treatment device. Background Technology

[0002] Leather is a durable material made by subjecting animal hides to a series of physical and chemical treatments that denature the collagen fibers. It possesses good strength, flexibility, and corrosion resistance. Tanning is a crucial step in leather making, primarily employing methods such as chrome tanning and vegetable tanning to transform raw hides into structurally stable leather that is less prone to decay. However, this process consumes large quantities of chemicals and generates significant amounts of high-concentration wastewater containing heavy metals like chromium, sulfides, organic matter, suspended solids, and persistent pollutants.

[0003] However, during the subsequent mixing and reaction with wastewater treatment solvents, harmful gases such as hydrogen sulfide and ammonia are easily generated, which can easily escape into the air, causing air pollution and potentially endangering the health and safety of operators. Therefore, improvements are urgently needed. Utility Model Content

The moving sleeve 23 moves the cleaning scraper 24, which scrapes off the leather fibers on the filter plate 7 and pushes them into the collection box 8, thus cleaning the filter plate 7 and facilitating subsequent wastewater treatment. The second motor 16 and the third motor 21 are then started to reset the filter plate 7 and the cleaning scraper 24. By manually adding wastewater treatment solvent, hydraulic cylinder 3 is activated, which drives the isolation cover 4 to move downward. The isolation cover 4, through the support plate 6, drives the mixing mechanism to move downward until the isolation cover 4 contacts the treatment tank 1, thus sealing the treatment tank 1. The isolation cover 4 drives one end of the suction pipe 10, which is fixedly connected to it, to move synchronously. The first motor 13 is activated, which drives the rotating roller 14 to rotate. The rotating rod drives multiple stirring components 15 to rotate. The stirring components 15 fully stir and mix the wastewater and wastewater treatment solvent in the treatment tank 1, promoting a uniform reaction between the two. During this process, the suction pump 9 is activated. The suction pump 9 extracts the harmful gases generated during the mixing process through the suction pipe 10 and inputs them into the purification box 11 through the gas delivery pipe 12.
