A hair filter structure of a garment leather chrome tanning device

Abstract

The invention provides a hair filter structure for a clothing leather chrome tanning device, and belongs to the operation field. The hair filter structure solves the technical problems of difficulty in processing waste liquor produced in an existing clothing leather chrome tanning device. The clothing leather chrome tanning device comprises a reaction tank with a reaction cavity, wherein the reaction tank is cylindrical; a rotary barrel is arranged in the reaction tank; a gap is formed between the outer side wall of the rotary barrel and the inner side wall of the reaction tank; the rotary barrel can rotate in the reaction tank. The hair filter structure of the clothing leather chrome tanning device comprises a plurality of fair collecting rods which are fixed on the tank wall of the reaction tank, and the hair collecting rods comprise rod bodies and forks perpendicular to the rod bodies. The hair filter structure has the advantage of being convenient to process the reaction liquor.

Description

technical field [0001] The invention belongs to the field of operations, and relates to a chrome tanning device for garment leather, in particular to a hair filtering structure for the chrome tanning device for garment leather. Background technique [0002] The production of garment leather requires the process of chrome tanning, which is the most important and widely used tanning method in the leather industry. The essence is the result of multi-point combination and cross-linking between the trivalent basic chromium complex and the carboxyl group on the side chain of skin collagen. The carboxyl ion entering the inner circle of the chromium complex coordinates with the central ion to form a strong coordination bond, which increases the stability of the collagen structure, and the shrinkage temperature of the leather can reach above 100°C. The chrome tanning method initially applied is a two-bath In the first bath, dichromic acid is used to treat bare leather, and in the se...

Problems solved by technology

[0003] In the chrome tanning process, it is necessary to fully contact the fur with the chrome tanning solution to obtain better quality leather. At present, the fur is soaked in the reaction tank during the chrome tanning process, and the fur is piled up in the reaction tank, resulting in fur The accumulation place does not have much contact with the chrome tanning solution, and the fur needs to be manually turned frequently, resulting in increased labor costs; in the chrome tanning process, the reaction solution is often added regularly, and the existing reaction pool cannot be uniformly dispersed due to the presence of fur In the reaction tank, the composition of the reaction solution in the reaction tank is uneven, which affects the quality of the leather; when the hair is chrome-tanned, there are often hairs, and the hair will fall off into the reaction solution after long-term soaking, and the reaction solution will disappear after one treatment. Scrapped, the existing reaction tank adopts the method of directly discharging the reaction solution to the sewage treatment system, and the hair is also discharged, which increases the burden on the sewage treatment system
