Description

t

This invention relates to the textile industry and can be used in the process of raw cotton processing at cotton ginneries.

The circuit of the invention is the sweeping effect due to better extraction of impurities.

1 shows a schematic of a cleaner; figure 2 - node I in figure 1; FIG. 3 is a section A-A in FIG. figure 1; Fig. 4 is a schematic of the construction of rib crofiles.

Fiber cleaner, for example, raw cotton contains food-1, the task of which is to uniformly feed the cleaner, saw cylinder 2, assembled from saws 3 and gaskets 4, between them is a removable drum 5. In conjunction with saw cylinder 2, grate bars 6 in the form of shafts with a corrugated surface 7, carrying disks 8, which enter the interpain space of the drum 2, on tube surfaces: which are made of curvilinear fins 9, whose working surfaces are shaped along lines that ensure their interaction with ub E saw cylinder an angle of 10 ,, - 15. The grate 6 is made rotatable in one direction with the saw cylinder. The distance b between the edges 9 of the adjacent disks 8 for eliminating the ginning on the cleansing layer exceeds the dimensions of the clouds and is 20-25 mm. In addition, with respect to each other, the edges 9 on the adjacent disks 8 can be installed in a staggered order, which also makes it possible to eliminate the construction.

The raw cotton, the passage of the feeder 1, is loosened and uniformly fed to the saw cylinder 2. A saw tooth having a front angle oi, 30-40, captures the raw cotton sheaves and drags them through the gaps. between the discs 8 of the rotating grate.

In this case, the saw teeth approach the axis of rotation of the grate, and then are removed, i.e. the angle of inclination of their front face constantly varies with respect to the plane connecting the axes of the saw cylinder and the grate. In order to avoid flying off the teeth when interacting with the ribs, it is necessary that the angle between the normal:

raw material attached to the teeth x, the passage of the gap between the disks, the edges of the ribs are cleaned from litter on both sides. The multiplicity of interaction of the voltages with the ribs is proportional to the number of ribs on the disks, the frequency of rotation of the saw cylinder and the grate,

g to their diameters and inversely proportional to their center distance. Thus, with a number of ribs equal to 12, equal to the frequencies of rotation and the diameters of the saw cylinder and the grate and the center distance, paBHONy is 1.5 times the diameter of the saw cylinder, the ratio of the interaction of the ribs with cotton tufts is 12-13 times. In addition, it is necessary to take into account the effect of the corrugated surface 7 on the bat.

The profile of the selected ribs is constructed as follows.} Center O, axis of rotation of the saw cylinder, Oy axis of rotation of the grid bars, D,.

Thus, a cleaning efficiency of q4eT is high at 1 | s, and the batting agent is exposed to the bat from various sides. The output of 1-row-55 months from the space between the disks 8 and the ribs 9 is due to the centrifugal force arising during the rotation of the grates.

Foresters 6 with corrugated surfaces 7, discs 8 and ribs 9 allow, in a single capture of cotton bales, the teeth of the saw cylinder 2 to replace the triple effect of the baffle bodies used in known cleaners. The fiber is removed from the saw cylinder by a detachable drum 5,
