INFLUENCE OF THE MESH SHAPE OF THE FINE LITTER CLEANER FOR RAW COTTON ON THE CLEANING EFFECT
Abstract
Increasing the efficiency of cleaning raw cotton from weeds will ultimately improve the quality of products in the textile industry. It has been established that when using cylindrical mesh on purifiers with peg drums, the exciting force acting on the strips from the side of the net has a stable frequency, determined mainly by the frequency of rotation of the peg drum. This mode of operation of the cleaner does not effectively remove trash impurities. To improve the efficiency of the cleaner, it is proposed to use a grid in the form of a multifaceted prism. It was found that, by design conditions, the minimum number of mesh faces is four. The dependence of the cleaning effect on the number of faces of the perforated mesh of the cleaner has been experimentally obtained. It was found that with an increase in the number of mesh edges, the cleaning effect and fiber damage decrease. With the number of faces equal to six, it is possible to achieve an increase in the cleaning effect by an average of 16 % with a slight increase in fibre damage.
