Description

In the proposed drum milk to separate fires from bast fibers, for example, when determining their coexistence to repeatedly pass the fiber between the drum and the milli rollers, in order to better clean the fiber from the bonfires, the flap installed between the rollers.

The drawing shows a schematic diagram of the scheme.

The supply table of the device is made in the form of a smooth sheet of iron Y or in the form of an endless moving nolotn. And in another case, on the surface of the feeding table there is a loose square in the form of a square or rectangle on which the test image is evenly distributed (fiber, stalks of trusts, etc.).

From the table 1, the fiber or the stems are fed to the rollers 2, which capture the layer, promote it and transfer it to the rollers 3.

Rollers 2, 3, 4, b - l 7 cylindrical corrugated. Roller groove 2 is larger than roller 3, while roller 3 is longer than roller 4, and r 4 fluted roller 4 is larger than roller 6. Roller groove 6 7 is the same.

Rollers 3 pass the fiber to rollers 4, which move it at a speed, the speed of the roller is 2 n 3. The speed of movement by the rollers 3 is average compared to the speed of rollers 3 and 4. These pairs of rollers (2, 3 and 4) are calculated on industrial layer, some thinning and parallelization of the fiber due to stretching and partial scraping of fires.

From rollers 4, the thinned layer of fiber enters the rollers 6 and 7. which form a kind of drum MYLKI. The speed of movement by the rollers 5 and 7 is greater than the speed of its movement by the rollers 4. Due to this difference, the speed of the layer of fiber of the fiber once again gets stretched and parallelized.

Promin between rollers 6 and 7, the fiber moves in a closed circle and does not go out until the flap 8 opens, with a smooth surface, facing the rollers. Flap 8 simultaneously w505

It is designed to allow the fiber to move with the surface of the drum drum 6.

The bearings of the upper rollers 2,3 and 4 and the rollers 7 are equipped with springs, which ensures the normal operation of the mill in case of random thickening of the layer.

The grooved surfaces of all the rollers interact with the neighboring ones due to the direct engagement of the grooves.

Drumming is set in motion by hand or by motor. The speed of the drum 6 is fixed by a worm counter with a bell.

The bonfires emitted during prome, grabbing, and scraping are collected in box 9. Bonfire from rollers 5 and 7 enters box 5 directly, and from rollers 2, 3, and 4 is sent to ngto with the aid of flap 5.

The fiber is processed on the ground until it is completely cleaned from the fires and transformed into the smallest woody particles that can stand out with very light airborne)} and x. The number of revolutions required for this for each type of fiber (flax, hemp, kenaf) is established in advance by developing the instructions for using the device.

It is possible that for some types of fiber, for complete cleaning, it will be necessary to pass it through a millicle with a certain number of revolutions not one, but several times, each time placing a layer of fiber on the table / subsequently one side of it, then the other.

Subject invention

Drum milk is used to separate fires from bast fibers, for example, when determining their zakostennosti, characterized in that, for the purpose of multiple passing of fiber between the drum and the milk rollers, a flap 8 installed between the rollers of the rollers is applied, fiber through the drum between the drum and the rolls.
