Rotary drum for improving internal baffle plate structure of drum body in leather production

Abstract

The invention relates to a rotary drum for improving an internal baffle plate structure of a drum body in leather production, which is provided with a drum body. The drum body is provided with a cylindrical drum inner container and a plurality of baffle plates which are installed in the drum inner container; and the drum inner container is provided with two drum side walls and a cylindrical drum inner wall. The bottom end of each baffle plate is in closed fixation connection with the circumference surface of the drum inner wall; two side ends of each baffle plate are respectively in closed fixation connection with the two drum side walls; the height of each baffle plate is one fifth to one third of the inner circle diameter of the drum inner wall; and in the cutting plane which is perpendicular to an axis of the drum inner container, an included angle formed by each baffle plate and the inner circle tangent of the drum inner wall at the connecting position of the bottom end of the baffle plate and the drum inner wall is 50-70 degrees. Accordingly, the rotary drum can bag and splash leather and liquid together during oriented rotation, thereby improving the loading rate and the working efficiency and having good leather processing effect.

Description

technical field [0001] The invention relates to a drum used in wet processing stages such as soaking, degreasing, tanning, retanning and dyeing in the tanning industry, especially a drum used in leather production to improve the internal baffle structure of the drum body . Background technique [0002] At present, my country is developing from a big leather country to a strong leather country, and the tanning industry is advancing towards energy saving, green and environmental protection, which requires the innovation of tanning equipment. The internal structure of the traditional drum used in tanning wet processing is several drum piles or low baffles (the height is about 1 / 10 of the drum diameter) or the combination of drum piles and low baffles. The main working principle During the rotation of the drum, the skin is picked up from the liquid and then thrown down when it is close to the highest point, and falls on the liquid or skin at the lower position of the drum, ther...
