Description

(54) DEVICE FOR MOISTENING TEXTILE MATERIAL

The invention relates to the textile industry and can be used np to moisten cotton fiber before it is pressed.

A device for continuous moistening and venting of textile material, containing a perforated drum with fans installed on its front sides, a humidifier located under the drum and a tray, is known. for directing air 1.

The known device does not provide sufficient uniformity of moistening of the material, which reduces the efficiency of moistening.

In order to increase the uniformity of moistening of the material in the proposed device, the guide tray is made in the form of a curved grating mounted concentrically with the drum surface. In this case, the grating contains longitudinal rods and blades fixed on them, which are rotatably mounted to change the living cross section of the grid, and the perforated drum is connected to the fan by means of a pipeline that has a gap along its length.

FIG. 1 shows a device for moistening a textile material (a variant of location in the pressing workshop of a cotton factory); in fig. 2 - section A - A of FIG. one.

Device for moistening textile material has located in the casing 1

mesh drum 2 and rollers 3. A humidifier 4 is installed under the drum 2, and between them is a guide 5, made. in the form of a curved grille and mounted concentrically on the surface of the drum 2. The grill contains longitudinal

the rods 6 and the blades 7 fixed on them with the possibility of mvrroth for changing the living section of the close-bridle. The drum 2 and the air humidifier 4 are connected via a pipe 8 to a fan 9. The pipeline is made with a break along its length

(on the discharge or suction branch)

On the mesh drum 2, the fiber is fed

roller 3. Under the action of circulating

in a humid air device, the fiber is pressed against the surface of the drum, continuously blown through, makes a complete turn and is removed by roller 3. The treated fiber is fed for packaging.

The fan of the air movement in the device is the fan 9, which directs it through the pipeline 8 to the air humidifier 4, where the air is saturated with moisture, directed to the drum 2 and passes through the fiber layer located on its surface. The exhaust air is sucked off by a fan 9. Moist air, passing through a layer of fiber, gives off some of its moisture and moistens it. The crate 5 stabilizes the flow of moist air and distributes it over the surface of the drum 2, which contributes to an increase in the uniformity of wetting of the fiber. By varying the living cross section of the grid 5, by turning the longitudinal bars 6, it is possible to adjust the uniform distribution of the humid air. The rupture of one of the branches of the pipeline 8 contributes to the improvement of the aerodynamic properties of the device.
