Description

Apparatuses for continuous dyeing of fibrous material are known, having a steamer chamber, belt conveyors, squeezing rollers, a loading and unloading device.

The proposed apparatus, in comparison with the known ones, allows to improve the quality of dyeing by holding it in a sealed chamber. For this purpose, the loading and unloading devices of the apparatus are made in the form of a shaft, partially filled with liquid, through which the processed fibrous material is loaded into the chamber and removed from it by means of a rake elevator.

In the apparatus, a tray mounted under the squeezing rollers can be used to collect liquid squeezed from the material being processed and return it to the mine, and dies to remove material from the elevator and feed it to the squeezing rollers.

The drawing shows schematically an apparatus for the continuous dyeing of a fibrous material.

At the entrance of the steam chamber / there is a loading device, representing a vertical shaft, inside which a rake elevator 2 and a comb 3 are installed. The lower part of the shaft is partially filled with working fluid. Behind the loading device shaft, squeezing rollers 4 are mounted on the path of movement of the material being processed; below the lower one there is an inclined tray 5 connected to the mine. The unloading device is similar in design to the loading device. Between the loading and unloading devices inside the steamer / inclined belt conveyor 6 is installed. The fibrous material is fed by the conveyor belt to the socket 7 and falls into the lower part of the loading device shaft, from where it is directed to the steamer chamber via a rake elevator. From the elevator, the material is removed by the comb 3, fed into the squeezing rolls-4, and then fed to the conveyor belt 6. The working fluid is pressed through the tray 5 back to the bottom of the loading device shaft. By the raking elevator 8 of the unloading device, the processed material is supplied to the clamping rollers 9 and then goes to the receiving conveyor belt 10. The working fluid in the lower part of the mines of the loading and unloading devices forms hydraulic locks sealing the pressure chamber / in which the required water vapor pressure is maintained.
