Problems solved by technology

[0003] During the tanning process, the raw hides are turned over in the drum for washing, pickling, tanning, dyeing and other processes. The treatment liquid in the drum contains a large amount of harmful chemicals and heavy metals. Accidental leakage will pollute the environment and endanger the health of workers. healthy
[0004] The degree of contact between the hide and the treatment liquid and the effective stretching of the hide will affect the process quality, while the existing drum adopts a mechanical action method combining cylindrical drum piles and long baffles to increase the effect of hide treatment, which is easy to tear the hide. Moreover, the work resistance is large, which is not conducive to improving efficiency

Abstract

The invention discloses a high-efficiency leakage-resistant rotating drum which comprises a machine frame and a hollow drum body, wherein a leakage-resistant tank is arranged below the drum body; one side of the leakage-resistant tank towards the outer surface of the drum body is provided with a cambered groove; the cambered groove is arranged in the circumferential direction of the drum body, and the heights of the openings on the two sides of the cambered groove are greater than the liquid level in the inner cavity of the drum body; the lower end of the leakage-resistant tank is provided with a liquid outlet pipe communicated with the cambered groove; the liquid outlet pipe is provided with a liquid outlet valve; elastic devices are uniformly distributed on the inner surface of the drum body in the axial direction of the drum body; and the elastic devices are connected with a wide partition board which can elastically rotate around the elastic devices. The high-efficiency leakage-resistant rotating drum can collect the treatment liquid leaked by the rotating drum to prevent pollution, and has the advantages of low breaking tendency of the hide, low working resistance and higher efficiency.

Description

technical field [0001] The invention relates to a rotary drum, in particular to a high-efficiency leak-proof rotary drum. [0002] technical background [0003] During the tanning process, the raw hides are turned over in the drum for washing, pickling, tanning, dyeing and other processes. The treatment liquid in the drum contains a large amount of harmful chemicals and heavy metals. Accidental leakage will pollute the environment and endanger the health of workers. healthy. [0004] The degree of contact between the hide and the treatment liquid and the effective stretching of the hide will affect the process quality, while the existing drum adopts a mechanical action method combining cylindrical drum piles and long baffles to increase the treatment effect of the hide, which is easy to tear the hide. And work resistance is big, is unfavorable for improving efficiency. Contents of the invention [0005] The technical problem to be solved by the present invention is to pro...
