The invention relates to the leather and fur industry, in particular to equipment that can be used in all liquid operations of leather and fur hides.

A device for chemical processing of hides and skins is known, which is a stationary cylindrical apparatus with an inclined longitudinal axis, at the end wall of which there is a rotating hollow cone, on which a system of helical planes extending to the upper end of the apparatus is fixed. The device is available in two versions,

In the first embodiment, the screw planes come close directly to the inner walls of the stationary cylinder.

In the second embodiment, the screw planes come close to the inner surface of the rotating perforated cylinder. In this case, the screw planes and the perforated tsindir have independent rotation ll.

In both cases of this device, the phenomenon of seizing of the semi-finished product between the inner surface of the cylinder and the screw-like planes is inevitable, and the hiding of skins on the screw planes is also possible. The drawbacks of the device are also low filling capacity of the tank, cumbersome structures, etc.

Closest to the present invention is an apparatus for liquid processing of hides, containing a tank with a horizontal axis, a screw mixer located on the axis of the tank, and a perforated false bottom, fixed in the tank under the mixer and along it zj.

However, by ensuring good mixing of the semi-finished product and the solution, it does not allow for the complete discharge of the semi-finished product.

The purpose of the invention is to facilitate the discharge of processed semi-finished product.

This goal is achieved by the fact that in the apparatus for the skin-dressing treatment of leather-fur semi-finished product containing a container with a horizontal axis, a screw stirrer located along the axis of the container and a perforated false bottom fixed in the container under the mixer and along it, the container is fixed and the sections The side wall of the container in its lower part is made straight and linear and located at an obtuse angle to the false bottom.

The auger mixer is conical in shape, and the perforated false bottom is parallel to the generator.

FIG. 1 schematically shows an apparatus, a general view; in fig. 2, section A-A in FIG. one; in fig. 3 screw agitators; in fig. 4 is a view B in FIG. one.

An apparatus for liquid processing of a leather and fur semi-finished product consists of a tank 1 with two walls: left (front) 2 and right (rear) 3; on the front wall 2 of tank 1, a cap is attached with a hatch 4 to unload the semi-finished product and a device for closing and opening the discharge cap hatch.

The screw mixer consists of pipe 6 and spiral-shaped coils 7. To enhance the effect of mixing the liquid with the semi-finished product, the blades 8 are attached to the screw turns. To facilitate unloading of the semi-finished product, the mixer is made conical in shape, the screw mixer is fixedly mounted on two bearings 9 and 10 fixed on the walls 2 and 3. The bearing housing 10 contains the stuffing box seal 11. The rotation of the stirrer is received from the gearbox 12 by means of sprockets 13 and 1 of the chain transmission.

For loading the processed semi-finished product, the apparatus is provided with a hatch closed by two pillars 15. Each krpnka equipped with rollers 16, fortified | MI on the OS. x, supports on the guides 17 fastened at the ends of the key 15.

To remove waste solutions, a perforated false bottom 18 is provided in the apparatus, which has an inclination angle equal to the cone angle of the auger agitator, i.e. the perforated false bottom is arranged parallel to the generator of the agitator.

The space between the bottom of the tank and the false bottom 18 is connected to two hatches that are closed by valve 19, by turning the handles 20. Through these hatches with valves 19, the spent solution is drained into the sewer system.

The cover with the hatch 4 is opened using the handle 21.

A hatch with a cover 22 is provided for cleaning the space between the bottom of the tank and the false bottom.

The device works as follows.

The container 1 through the hatches closed with clamps 15, loads the semi-finished product, then pours the required amount of water and chemical solutions into it (the semi-finished product can also be loaded after filling the container with the necessary amount of water), then turn on the screw stirrer, which performs reverse rotation, as a result, the processed semi-finished product is mixed together with the working solution. After a certain time required for the technological operation to be carried out in the apparatus, the screw stirrer is stopped. The spent working solution is drained through the false bottom 18 by means of valves 19. After sufficient discharge of the spent solution, the valves 19 are closed, water and chemical solutions for the latter are poured into the apparatus

the technological operation after which the apparatus is prepared for unloading. For this auger agitator reported rotation in one

g direction (to ensure the movement of the semi-finished product in the direction of the discharge hatch). Then, by rotating the handle 21, the lid 4 is opened and the processed semi-finished product combined with the liquid is withdrawn from the vessel of the apparatus. In order for the apparatus to fully discharge the semifinished product in the lower part of the container, the portions of the box wall are straight and are located at an obtuse angle to the false bottom with a maximum approach of the side wall to the helical surface of the turns of the screw shaft.

0 The device of the proposed design allows to carry out technological operations without overloading (by achieving an intensive solution of the solution in the device itself) and thus facilitates

5 work conditions. The closed form of the fixed container improves working conditions and also ensures safe sanitary and hygienic working conditions.
