Definitions
- This application refers to improvements in drums used in the tanning industry, which are related to the shape and relative location of the shelves provided in the inside of such drums.
- Tanning drums used in processing of skins, hides and leather are closed rotatory drums. These rotatory drums have the main purpose of mixing the skins, water and chemicals.
- drums In order for this mixing effect to be efficient, these drums have traditionally had in their interior a series of devices to favor this mixture.
- the aims of these arrangements are to transform the electrical motor power into
- the present innovation refers to item 2).
- the shelves, paddles or tables are arranged longitudinally in the inner surface of the drums and they are radially placed, with heights of not more than 40 centimeters (16 inches approx.).
- US-A-6 151 932 discloses the construction of drums with "inner bats” placed in a non-radial arrangement, which formed a certain angle with respect to the tangent in its strongpoint on the surface of the drum, and with heights of between 60 and 150 cm. See B in Figure 1.
- the present innovation refers to an amendment in the traditional radial shelves.
- the length of the shelves is extended substantially and a additional tilted table is attached thereto in their ends forming a certain angle, or a spoon-shaped curved element. See C in Figure 1.
- This additional element cant be oriented in one or in both rotation directions.
- the overall height of the shelves plus the additional portion varies between 10 and 40% of the internal diameter of the drum.
- the angle formed between the shelf and the additional portion (in case of a straight table), varies between 90° and 180°, in one direction or both.
- the amount of radial shelves with the additional portion can vary from 2 to 10 and it is variable for each dimension of drum and each type of process that will be performed.
- the drums with this innovation can run between 0,5 and 10 rpm in both directions.
- This innovation can be applied in any process where rotatory drums are used, such as Soaking, liming, deliming, pickling, tanning, degreasing, retanning, neutralization or de-acidification, dyeing, fat liquoring, dry milling.
