Description

The present invention relates to the field of clothing and textiles and is intended for treating porous materials (leather, textiles) with liquids (chemical solutions).

Traditionally, porous materials (skins, textiles) are treated with chemical reagents in containers of various construction (baths, rotary drums) where they are soaked in solutions. Such equipment undergoes a periodic intermittent and inefficient process.

The object of the present invention is to provide a continuous operation device for treating porous materials with liquids.

There is a known device for treating leather semi-finished products with liquids (SU 1407955, C14C15 / 00), in which a skin blank for processing is applied to a lower chamber with a metal support and filter material, which is fixed in a plate corresponding to the outline of the leather blank. Attaches the upper chamber to the lower chamber with the skin preform and the locking plate. The bottom and top chambers are tightly sealed. The solution is fed to the upper chamber. The solution drips through the skin for processing into the lower chamber where it is removed. The disadvantage of a device of this design is that each workpiece of different shape and size is sealed by a perimeter plate with a hole corresponding to the outline of the workpiece. In addition, this unit is difficult to adapt to continuous operation.

Known apparatus for chemical treatment of leather (LT 5096B, C14C15 / 00) having a vacuum chamber covered with a perforated plate and a contour forming device located in a vacuum chamber under the perforated plate. The disadvantage of this device is that each skin must be re-contoured to its perimeter and the chemical treatment process is done by moving the vacuum chamber.

The closest known technical solution is the skin treatment method (LT 5095B C14C3 / 06; C14C3 / 30), which, under pressure, injects a solution of a substance, such as a solution of chromium salts, into the treated skin. The nozzle of the syringe is pressed against the treated skin so that the nozzle is in direct contact with the treated skin. The syringe nozzle is then moved to other areas of the skin to be treated with the aid of a numerical control. The injection points are positioned so that the adjacent penetration areas of the chemical solutions overlap partially and cover the entire surface of the skin. The disadvantages of this device are that each skin must be re-contoured to its perimeter, and the skin treatment process cannot be performed continuously.

Patented device for treating porous materials with liquids, consisting of a housing with fluid supply and vacuum systems mounted thereon or connected thereto, a controller, an electric motor (s). Its housing contains an electric motor-driven perforated cylinder with a vacuum chamber inside and a fluid (s) injection head inside.

The patented device for processing porous materials has fluid-perforated perforated cylinder bore diameters of 1 to 5 mm in length and 5 to 10 mm spacing.

In the patented device for treating porous materials with liquids, the vacuum chamber is pressed against the inner surface of the perforated cylinder by spring supports mounted on a stationary hollow axis.

The patented device for treating porous materials with liquids has a plurality of injection openings in the injection head which are arranged so that the adjacent penetration areas of the liquids (chemical solutions) partially overlap.

The injecting head of the fluid (s) of the patented device is connected to the fluid delivery system and to a device for changing its position above the material to be treated.

In the fluid-treated porous material of the patented device, the injector head is pressed against the material to be treated by an electromagnetic squeegee of the positioning device and is moved to another location of the material being processed by an electric motor.

The invention is illustrated by the following drawings:

FIG. 1 - principle kinematic diagram of the device;

FIG. 2 is a cross-sectional view of the device.

FIG. Figure 1 shows the principle kinematic diagram of the device.

The device for treating porous materials with liquids has a housing 1 having a fixed hollow axis 2 on which is movably mounted a rotatable perforated cylinder 3 rotated by a transfer mechanism 4. A vacuum chamber 5 is mounted inside the perforated rotating cylinder 3 on the fixed hollow axis 2 The vacuum chamber 5 comprises a nozzle 7 for connecting the vacuum line 8 to the vacuum pump 9. The vacuum chamber 5 consists of a rigid plastic trough, the walls and ends of which are rounded by the radius of the inner surface of the cylinder 3.

Above the rotatable cylinder 3 and on the surface thereof, the porous material 10 to be treated is a chemical insertion injector head 11. The injector head 11 is connected to its position guide 12 and to the solder pressurized with the material to be treated. The transfer mechanism 4, the vacuum pump 9, the injector head position guide 12, its sensor 13, and the fluid delivery system 14 are controlled by a controller 15 via motors 16.

FIG. Figure 2 is a cross-sectional view of the device.

The housing 1 and the rotatable perforated cylinder 3 are provided with a treatment material 10 which is fitted to the cylinder 3 by a vacuum chamber 5 connected via a nozzle 7 to a vacuum line. Above the treatment material 10 is an injection head 11 having a plurality of injection apertures which are pressed against the treatment material by an electromagnetic press 13 and are displaced by a position guide 12 and connected to a fluid supply system 14 and a controller 15.

The device works as follows:

On the housing 1 and the rotating perforated cylinder 3, the process material 10 is laid, the vacuum pump 9, the fluid supply system 14 and the controller 15 are actuated. The fluid supply system comprises the whole - pump, fluid reservoirs, valves, pressure and flow regulators, etc. It operates in constant mode and only triggers injection pulses at the command of the controller.

Enters a material processing program into the controller, and activates its execution. The controller sets the injector head 11 to its original position, holds it to the material being treated, and injects the chemical solution. The injection duration is about 0.01 s. The injection head has a plurality of injection apertures arranged so that the adjacent penetration areas of the fluid (chemical solutions) overlap partially.

The injection head 11 is displaced by a positioning device 12 in a calculated step, thereby repeating the injection cycle to the edge of the material to be treated. The perforated cylinder 3 is then rotated at a calculated angle so that another area of untreated material is placed under the injection head 11, while being moved to the starting position of the new row and repeating the injection cycles. During the application of the materials to be treated, the process proceeds continuously.

The patented design reduces the processing time per unit batch by 2 to 5 times. It can also handle materials of different widths, lengths and configurations.
