A perforated drum is arranged inside the housing fixed to the frame, which has the possibility of reverse rotation. Inside the drum screw partitions and transverse shelves are fixed. The body is installed with the ability to rotate at an angle from -15 to 45 k. Horizontal, 3 Il.

Description

This invention relates to; to light industry.

The purpose of the invention is to improve the intensification of the service.

Fig. 1 is a schematic diagram of the apparatus; FIG. 2 is a section A-A in FIG. fig.Z - node I in figure 1.

The device contains a frame 1, a detachable body 2 with a door 3 of the loading / unloading hatch fixed on it, a perforated drum 4 mounted inside the body with the possibility of reversible rotation, supported on rollers 5. The drum has partitions 6 located along helix 5 and transverse. shelves 7. There is a hydraulic cylinder 8, a solution supply system with a valve 9, a reservoir 10, a cold and hot water valve 11, an air-steam valve 12, a solution recirculation system and a waste liquid drain with a valve 13., a vacuum system my pipe with 14 and drive.

The body 2 is made detachable, it is made of a hollow cylinder and a conical throat, inside it is covered with a protective coating5 and the outside is equipped with a heat insulating jacket. , the drum 4 is self-mounted by the rollers 5 attached to the housing 2, the tightness of the apparatus is ensured by the door 3, SH10TNO adjacent to the housing 2,, inside the drum 4, three screw partitions are fixed 6 with variable pitch and two transverse shelves 7. The housing 2 is rigidly fastened to the bed 1, which changes the angle of inclination from -15 to + 45 ° using hydraulic cylinders 8 attached to the trunnion 16 mounted on the bed of the drain the solutions are produced through the pipe and the valve 3, air and steam are supplied through the valve 12, the solution is recycled. Through the valve 17, air is pumped out through the pipe 14 by a vacuum system. The water supply is carried out through the valve 11, and the solutions through the valve 9 using the tank 10, the drum is rigidly fixed to the reinforced bottom

with the axle shaft 18, laid in the hub with bearings 19, the internal drum of the apparatus is driven

from the electric motor 20 through the V-belt drive 21, the variator 22, the gearbox 23 and the chain gear 24.

The device works as follows.

The device with the door 3 open is positioned at an angle to the horizontal, the raw material can be supplied by a conveyor, hoist, and loader. Include in the work of perforated b Arabian 4 so

so that the course of the baffles of the partitions moved the raw material to the steel bottom. At the same time, depending on the process, the working solution is supplied from the chemical station through tank 10, valve 9. Water is supplied through valve 11 to a certain level for this process. The process of loading and feeding the solution occurs simultaneously. Close the door 3, hydraulic cylinders

8 changes the angle of inclination of the frame 1 for this process and includes the apparatus in operating mode. The direction of rotation of the drum 4 varies. When the rotation of the drum is directed so

so that the screw partitions 6 move the semi-finished product and the working solution down to the steel bottom, as the semi-finished product accumulates at the bottom, the product begins to roll over

through the screw partitions and move upwards towards the main flow, i.e. the semifinished product does not move in one plane, but in space. When the rotation of the drum changes, the screw partitions move the semifinished product upwards, but the body of the apparatus is at an angle to the horizontal and the transverse shelves 7 knock the semifinished product down towards the main

flow, semi-finished product. When this occurs, the movement of the semi-finished product, similar to the movement of the semi-finished product roll in a barrel with a horizontal axis. However, in inclined drums, due to screw partitions, the semi-finished product moves not in the same plane, but in space, which reduces its twisting and improves the diffusion of chemical reagents.

in the thickness of the semi-finished product. With the inclusion of a drum in the operating mode, a system for processing a semi-finished product under pressure, with pulsating or with reduced pressure is enabled, which allows

Claims (1)

Claim The apparatus is for the liquid treatment of hides, nails and leathers, containing a body enclosed on it with a hatch for loading and unloading, a perforated drum installed inside is still suitable for use, then it is returned to the chemical station using the solution recirculation system. Open valve 15 to supply solution. The cycle of the apparatus is repeated, the angle of inclination, the frequency of rotation of the drum 4, the temperature of the solution and pressure are changed. After successive operations, soaking, gilding, softening, pickling, tanning and dyeing open the door 3, the tilt angle of the apparatus changes to -15, turn on the drum 4 so that when the screw partitions 6 are rotated, the semi-finished product moves to the hatch of the case. The time of the case with the possibility of reversible rotation and having inside the partitions located along the helical line, supply systems for solutions, steam and air, an exhaust system for draining the waste solution and a drive, characterized in that, in order to intensify processing and improve service conditions inside the perforated drum there are transverse shelves preventing the semi-finished product from being unloaded by screw baffles during version 25, and the casing is mounted with the possibility of rotation through an angle from (-15) to (+45) to the horizontal. h / Λ P Ί G ✓ \ h Ϊ that- Part 1 J to h g H ( that h / ) to 7 to 7 / fig.Z
