SU1392110A1 - Drum for liquid treatment of leather - Google Patents

Abstract

This invention relates to light industrial performance and allows for improved skin discharge from a drum for liquid treatment. The drum has a cylindrical shell 1 with bottoms 2 and false bottoms 3, filled with conical rings adjacent directly to the hatch 4. False bottoms: have alternating non-perforated and perforated sections, one of the non-perforated sections of each of the bottom adjacent to the corresponding edge of the hatch 4 3 il.

The invention relates to the tannery industry, namely to devices for physicists: gf1 wrapping of the tanning half-finished product.

The purpose of the inventor is to improve the output of the skin of the drum,

The drum contains a shchivdricheskoy ybechayku 1, two main bottoms 2, two perforated false bottoms 3 ,, made in the form of conical rings, rifled with one end to the bases of the rtbM bottoms, and the other to the shell directly to the corresponding hole of the door 4. Ro from the conical rings are placed perforated 5 and non-perforated b sections; alternating with each other. In this case, the unperforated portions of the surface of each of the conical rings are adjacent to the corresponding hatch KjpoMKe 4. The waste piacTBopoB is discharged: through the valves 7 located on the side or the cage 4, the drum is filled with the working solution either through the l) or 4, or through the floor of the 8-drum. For intensive processing

In one of the sections, one of the sections without perforation of each nM fist and flange can be installed. 55 rings directly adjacent to:

Through the hatch 4, a tanning semi-finished product and solution are loaded into the drum and, closing the hatch cover, the drum is brought in,
