Description

Technical Field

[0001] The utility model relates to the technical field of leather production wastewater treatment, in particular to a leather production wastewater treatment device. Background Art

[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processes such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster and feels comfortable. Leather processing is the process of chemically and physically and mechanically treating raw hides to make them into leather. This processing is divided into pre-tanning preparation, tanning, and finishing according to the processing procedures. A large amount of sewage will be generated in the leather production process, and in order to facilitate the purification of the generated sewage, a leather production sewage treatment device is required.

[0003] The Chinese patent disclosed patent number CN107089693A is a sewage treatment device for leather factory production. When in use, the sewage is introduced into the interior of the sewage treatment device body through the water inlet. After the treatment is completed, the purified water is discharged through the water outlet, and the dirt that needs further treatment is discharged through the sewage outlet. The movable plate is used to place the sewage collecting bucket. The sewage collecting bucket can be easily replaced by pulling the movable plate along the guide rail. When the inner wall of the device needs to be cleaned, the second top cover is covered, and the water pipe is connected to the water source. Under the rotating spray of the spray head, the purpose of cleaning can be easily achieved.

[0004] The disadvantage of the sewage treatment device in the leather factory production is that since the sewage directly passes into the interior of the sewage treatment device body from the water inlet, and since there may be some larger impurities in the sewage, if it is not filtered in advance, the impurities will accumulate inside the sewage treatment device body, making it inconvenient to remove them, and at the same time, the water inlet may be blocked and unable to work. Therefore, it is necessary to propose a leather production sewage treatment device to solve the above-mentioned problems. Utility Model Content
