The proposed device contains a drying chamber, consisting of the upper 1 and lower 2 sections (see figure 1) located on the frame 3, and connected to the pneumatic system. Sections 1, 2 are installed in open parts, one opposite the other. Heaters 4 are located between the housing of each section 1, 2 and thermal insulation 5. Each of the sections 1, 2 is equipped with gaskets 6. Between sections 1, 2 a movable cover 7 is placed for their sealing. On the lid 7 on both sides are fixed containers 8 and 9 for cyclodinamic supply of compressed air to removable pneumodynamic chambers 10 (see figure 1, figure 2). Pneumodynamic chambers 10 are rigidly mounted on couplings 11, which are placed on the surface of each tank 8 and 9. The cover 7 is mounted with the possibility of a drive to move from one section 2 to another 1 from the power cylinders 12 and 13. Inside each section 1 and 2, fans 14 are installed and 15 for uniform circulation of hot air and with the possibility of shutdown after opening the section. Pneumodynamic chambers 10 (see figure 3) are made in the form of petal nozzles, which consist of an upper outer ring 16 with a thread, external 17 and internal 18 rings. On each outer 17 or inner 18 ring of the nozzle, as well as the upper outer ring 16 with a threaded flap nozzle of the pneumodynamic chamber 10, a ring 21 with fastenings for the petals 22 and straps 23 is mounted and fixed with screws 19 and washers 20. Between the paired rings, the upper outer 16 with a thread, external 17 and internal 18, there are four slats 23, and in each of the upper pair of rings, be it the outer 17 or inner 18 ring, as well as in the upper outer ring 16 with the threaded strap 23 are movable in the ring 21 with fasteners for petals 22 and strips 23, and in each lower ring 21 with fastenings for the petals 22 and strips 23 are fixedly fixed with pins 24, fixed with lock washers 25. On each upper pair of rings in the rings 21 with fasteners for the petals 22 and strips 23 four petals 22 are movably fixed with pins 26 and fixed with lock washers 25 with washers 27 placed under them. The petals 22 are movably connected to the strips 23 via pushers 28, with two pushers 28 for each lobe 22.

A platform 29 is installed at the base of the pneumodynamic chamber 10, to which the pneumodynamic chamber 10 is fixed with an outer lower ring 30 with a ribbed surface against sliding of the processed fur skin 31, four screws 32 with washers 33, to which the processed fur skin 31 is attached using the clamp 34; the clamp 34 is tightened with a screw 35 (see Fig.9). Also, a half nut 36 of the coupling 11 is attached to the platform 29 with two bolts 37 with washers 38 for connecting the pneumodynamic chamber 10 to the device.

For the tightness of the connection of the half nut 36 of the coupling 11 with the platform 29, a rubber gasket 39 is installed between them.

For tightness of the connection in the sleeve 11 in the nut 36 of the sleeve 11 is installed a rubber seal 40.

To carry out the work of the pneumodynamic chamber 10, a bellows 41 is installed inside it, into which compressed air is cyclically supplied.

At one end of the bellows 41 there is fixed a plug 42 with a thread for its connection with the upper outer ring 16 with the thread of the upper flap nozzle of the pneumodynamic chamber 10, and the other end of the bellows is mounted on the nozzle of the platform 29. For tight connection of the bellows 41, the plug with thread 42 and the nozzle of the platform 29 clamps 43 are used. Clamps 43 are pulled together by screws 44.

Outer 16, 17, 30 and inner 18 rings are connected by pairing screws 45 with washers 46, and pairing screws 45 are tightened with pairing nuts 47 through the wall of the outer ring 16, 17, 30. And in the inner rings 18 there are elongated holes for pairing nuts 47 for the movement of the outer 16, 17 and inner 18 rings relative to each other along their common axis.

The connection of the petals 22, strips 23, pushers 28 are made using pins 48, 49, which are fixed with lock washers 25 with washers 27 placed under them.

Materials used in the manufacture of petal pneumodynamic chambers 10:

rings of petal nozzles: external 16, 17, 30, internal 18, ring 21 with fastenings for petals 22 and strips 23, petals 22, cork 42, platform 29, clamp 34, pairing nuts 47 are made of plastic. Pins 24, 26, 48, 49, straps 23, pushers 28, screws 19, 32, 44, 45, bolts 37, washers 20, 27, 38, 46, lock washers 25, clamps 43 are made of steel. The half nut 36 of the clutch 11 is made of aluminum. Bellows 41, gasket 39, seal 40 are made of rubber.

Assembly of the lower and inner parts is as follows. A rubber gasket 39 is placed on the half nut 36 of the coupling 11. Then, the half nut 36 of the coupling 11 is aligned with the platform 29 through the holes and connected by two bolts 37. Next, a rubber bellows 41 is mounted on the nozzle of the platform 29 and secured to seal the connection with a collar 43. Then, on the other end of the rubber The bellows 43 is fitted with a plug 42 and is also secured with a collar 43.

Assembly of the outer part is as follows. On each ring of the petal nozzle, a ring 21 with fastenings for the petals 22 and strips 23 is mounted and fastened with screws 19. Moreover, on the upper outer ring 16 with a thread for the plug 42, a ring 21 with fastenings for the petals 22 and strips 23 is installed in its upper part, and on the rest in the middle of the ring. On the ring 21 with mounts for the petals 22 and the strips 23, the petals 22 are installed with the pushers 28 and the strips 23 pre-connected to them, the strips 23 are pushed into the holes in the rings 21, then the petals 22 are movably fastened with pins 26, which are fixed by lock washers 25 with them with washers 27. Next, an inner ring 18 is installed in the outer ring 16, 17 with a ring 21 pre-mounted on it with fastenings for the petals 22 and strips 23, the rings are aligned with holes located in the walls, and through the wall The outer rings 16, 17, the pairing screws 45 with washers 46 are pulled together with the pairing nuts 47. And so on. The latter sets the outer lower ring 30 with a ribbed surface. On the lower petal nozzle on the inner ring 18, the petals 22 are not installed.

The final assembly is as follows. A hook is pushed into the hole located in the upper outer ring 16 and clings to the hole in the plug with thread 42, then the plug is pulled to the upper outer ring 16, rotating the pneumodynamic chamber 10 from the typed petal nozzles counterclockwise, screwed onto the plug with thread 42 until emphasis. Then the pneumodynamic chamber 10 is combined with the holes on the platform 29 and fastened with it with screws 32 with washers 33.

A device for the impregnation, bedding and drying of fur skins processed "stocking", works as follows. The device operates on compressed air. Air is supplied to the rubber bellows 41 (see FIG. 3), the bellows 41 extends axially, pushing the upper outer ring 16 with a threaded plug 42. The pneumatic chamber 10 extends in length, dragging adjacent adjacent screws 45 and nuts 47 rings. The upper pair ring 16, 17 with the petals 22 fixed on it extends upward from the lower ring (see Fig. 3, Fig. 6). The bar 23 remains stationary relative to the lower ring (see Fig. 3, Fig. 6), and the pushers 28 are rotated relative to the axes of the pins 49, with which they are movably connected to the strips 23 and the petals 22. The pushers 28 begin to push the petals 22, and they the turn is rotated relative to the axis of the pins 26.

The processed fur skin 31, fixed to the outer lower ring 30 with a ribbed surface against sliding of the processed fur skin 31 by means of a clamp 34 tightened by a screw 35, is pulled in length by pulling the pneumodynamic chamber 10, and by turning the petals 22 it is pulled in the radial direction.

In the manufacture of petals 22 of various shapes, it is possible to increase the diameter of a given pneumodynamic chamber 10, and therefore, process fur skins with a larger stocking diameter. By adding paired rings, it is possible to increase the length of this device by the length required by the fur skin.

The use of the invention in comparison with the prototype (see patent No. 2257588, IPC СВВ 1/40, Bull. No. 32, 11/20/2006) provides the following advantages:

- increasing the productivity of the device due to the alternate loading and processing of semi-finished fur skins, also due to the intensification of the process of impregnation, bedding and drying;

- improving the quality of the impregnation of the porous material due to the uniform introduction of the working solution deep into the skin tissue of the fur skins;

- increase in the area of processed fur skins due to cyclodynamic tension-compression of the working bodies;

- improving the quality of drying by circulating hot air with a fan in a closed section.

The proposed design of the device can be widely used in leather and fur production, can be used for piece processing of fur semi-finished products with emulsions of the second kind of water-in-oil type.

Based on the foregoing, we can conclude that the claimed invention meets the criterion of "industrial applicability".
