SU75160A1 - Drum for processing hides, leathers, etc. - Google Patents

Description

Drums for processing hides, leathers and the like, periodically immersed by means of lifting means in vats of liquid and rotated in the immersed state, are already known.

The proposed drum for processing skin | r, leather and the like differs from those known in that, in order to facilitate the unloading and loading of hides, it is made detachable in the axial plane, with both drum halves fixed during operation on the drive shaft, have unloading hatches, while the walls of the drum consist of pipes lined with metal mesh; along the sides of the drum, special combs are reinforced, which, when the drum rotates, prevent precipitation in the liquid. In FIG. 1 shows a longitudinal section of the drum; in fig. 2 is a top view of the drum; in fig. 3 is a side view of the drum; FIG. 4 shows a cross-sectional diagram of a drum placed in a diffuser.

A drum for treating the cheek pads of the like is placed in a reinforced concrete basin / having a semicircular shape at the bottom.

In this, a steel basin is installed on the thrust bearings on the thrust bearings.

shaft 2 over the entire length of the basin and wearing gear 3 with the same diameter as the drum to be mounted.

Square frames are riveted on the shaft from the top and bottom sides, to which the combs 5 are attached to the longitudinal sides.

These combs have the purpose to place the settling podzol on the move and to choose wool that settles the B pzole.

Both drum halves (containers) 6 are mounted on these frames. The container is attached to the frame by means of bolts welded by its lower ends to the drive shaft.

The container frame is made of light angular metal, la, and the tank fasteners are made of aluminum or thin-walled steel pipes 7, which after flaring in frame squares are sealed from the end.

In order to prevent the cheeks from falling out of the container, from the outside it is exposed to a metal net 8, the thickness of which, and the size of its cells depend on the processed hides. For fine skins, the mesh is very frequent and thin, and for larger ones, more rare.

Drum-ksteyner has two hatches. The upper loading hatch, through which the raw material is loaded or fed, and the lower hatch, through which unloading takes place after the container is transferred by crane to one or another place.

The work in the drum is carried out as follows: after the containers are installed on the frame and fixed on the frame (alternating loading of cheeks is carried out through the upper hatch of the container).

After sufficient watering, depending on the degree of preservation of the hides, the container, using lifting devices (cranes and taifers), lifts with four hooks hooked to the rings 9, pre-fitting nuts with bolts, pressing the container to the frame, and transferring it to the place where it is necessary send shkury to production purposes.

Unloading from the container is effected by pushing two locks of the container lower hatch, from where the logs are unloaded onto the production site.

Instead of a concrete basin, the drum can be placed in a special diffuser.

A diffuser container is designed for the extraction of any tanning materials, and especially for those that become crushed and even crushed when crushed.

According to the extraction of tanning materials, the diffuser-container: ep can be used for the study of soot-ash, softening, tanning and fatty processes in the leather industry and for treating sheepskin in fur and sheepskin.

The diffuser itself is made of wood, reinforced concrete or non-corrosive metal.

From above, in order to avoid cooling juices and other liquids, the diffuser is tightly closed with a lid, which is lifted by a crane in front of the recess of the container from the diffuser and placed on the adjacent diffuser. : Diffusers are installed in batteries, state 1 ii3 of eight to nine diffusers.

Each diffuser is divided into two halves by a wall; A copper-coated shaft with a stuffing sleeve passes through this wall, which does not allow the juice to pass through the hole. For the passage of juices from one compartment to another in} 1, an opening is made in the inner part of the partition.

Water, having a temperature of up to 100 °, is poured from a specially arranged tank into the tail cone, and the liquid passes from the tail cone to the subsequent cones by gravity.

Water enters the first compartment of the diffuser from above, washes tannins rotating in containers, passes through the opening of the diffuser partition wall to the second compartment, and from the top through the copper connecting pipe to the second diffuser, etc.

In this Extraction Method, each particle of tanning material is bathed in liquid, regardless of its size.

The design of the drum containers when using diffusers is the same as that of the drum installed in the pool.
