Abstract

The invention provides an inner cavity structure for leather liming dehairing. The inner cavity structure for leather liming dehairing is used for solving the problem about how to improve the contactdegree of the inner surface of leather and treating fluid during centrifugal rotating of the leather. The inner cavity structure comprises an inner cavity for containing the leather and pile heads arranged in the inner cavity. The pile heads are fixed to the inner wall of the inner cavity and are different in length and thickness, and a fluctuant impact surface is defined by the pile heads. The adjacent pile heads are connected through serpentine coil springs which define a rebounding surface, and the rebounding surface is located between the inner wall of the inner cavity and the impact surface.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and relates to an inner cavity structure for liming and dehairing of leather. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tannin. It has natural grain and luster, and feels comfortable. It is used in leather applications such as household leather. [0003] A drum is a rotary device in which raw hides are turned inside (such as for washing, pickling, tanning, dyeing) or for cleaning furs inside (by turning together with fine sawdust) during the tanning process. It is an important equipment widely used in tanneries , when driven by the motor, the leather in the drum is subject to mechanical actions such as bending, stretching, smashing, stirring, etc., which speeds up the chemical reaction process and changes the physical properties of the leather. The application range of the d...
