Description

Apparatus for liquid treating skins by pumping the treatment fluid through the skin are known, including a plate having through holes and cells filled with working fluid under pressure.

The proposed apparatus for the liquid treatment of leather ensures the continuity of the process.

To this end, the device is equipped with a conveyor for moving leather in it, two supporting conveyors and one string conveyor holding the skin at the time of treatment under the slab; the plate, supporting conveyors and one branch of the string, conveyor and conveyor to move are placed in the bath with the working fluid, and under the plate there is a reinforced elastic sheet interacting through the conveyor with the skin at the time of treatment.

FIG. 1 shows a diagram of the apparatus; in fig. 2 is a diagram of the plate unit and the elastic sheet.

One of the main components of the apparatus is a plate /, made with through holes 2 and cells 5 filled with working fluid, also located in the bath 4.

To move the leathers inside the apparatus serves as a conveyor 5: to support the leathers and prevent them from slipping off the conveyor belt 5, there are two supporting conveyors 6 and 7 located above the inclined sections of the upper branch of the conveyor 5; A string conveyor 8 is installed to hold the leather under the slab 1 (at the time of processing). The slab /, the conveyors 6 w. 7. One branch of the string conveyor 8 and one branch of the conveyor 5 are located in the bath 4 with the working fluid. All conveyors move synchronously. The conveyor 5 is pressed against the plate / elastic pillowJ o 138691-2koy 9, which is affected by pneumatic pressure W. The flow of working fluid into the plate 1 is made by pumps // and 12 through valve boxes 13 and 14. The treated skin 15 is loaded (hair down) into the machine at station 16 and move further under the slab; the elastic sub-block 9 also provides a seal for the holes in the plate}, in front of which there is no processed material, thereby eliminating leakage of the working fluid.

The working fluid is supplied to the plate 1 and presses on the areas of the raw material located under the holes 2, is pressed through the pores of the skin into the dermis layer and moves along the skin fibers towards the cells 3. When equilibrium is reached between the pressure force of the liquid in the plate cavity / and the force pressing the sheet 9 remaining with the liquid (excess) is squeezed into the gap between the plate cells and the surface of the raw material. During the reverse movement of the portions of the pumps 11 and 12, a vacuum is created in the cavity of the plate 1 and fluid is removed from the dermis of the skin (previously injected into it).

The dermis is thus dehydrated several times and therefore loosens. The duty cycle of skin treatment is repeated at a frequency of 5-6 times per second.,

Before leaving the apparatus, the skin is pressed by the shafts 17 and 18.

Subject invention

An apparatus for treating leathers by forcing the treatment fluid through the skin, including a plate provided with holes to form cells in the plate body filled with working fluid under pressure, characterized in that the apparatus is equipped with a conveyor to ensure continuity of the process leather, two supporting conveyors and one string conveyor that holds the skin at the time of treatment under the slab, the plate, supporting conveyors and one branch of the string conveyor EPA and a conveyor for moving the skin are placed in a bath of working fluid and under the slab reinforced elastic poduschka; interacting through the skin with the skin at the time of treatment.
