Method for Reducing Energy Consumption in Cotton Ginning

As is well known, at present, saving electricity is one of the priorities of all types of production where it is consumed.

In the technological process of primary processing of raw cotton, one of the main transitions is ginning. In a saw gin, the main amount of electricity consumed is accounted for by overcoming the forces of friction of the raw roller against the inner surface of the working chamber and the forces of separation of the fibers from the seed. Thus, it can be noted that a decrease in the friction force of the raw roller on the inner surface of the working chamber leads to energy savings [1-3].

In order to reduce the friction of the raw roller on the inner surface of the working chamber, a working chamber of the saw gin was developed with heating of these surfaces, because with increasing temperature, the coefficient of friction of fibrous materials on the steel surface decreases [4-6].

In connection with the above, it became necessary to conduct research to determine the change in the coefficient of friction of a fibrous material on a steel surface at different surface temperatures [7-9]. For this, a device was created to implement the proposed method (Figure 1).

The method is carried out as follows: for greater purity of experiments, the sample is preliminarily cleaned from trash. After that, they are installed on the marked point of the start of movement on an inclined surface preheated to the required temperature. After that, a flat weight is applied to the sample and movement is reported. In this case, the time of movement of the sample from the beginning of the point of movement to the end point of movement is fixed and the coefficient of friction is calculated [10-12].

Table 1: Number of Subjects at Each Site.

As can be seen from the tables and graphs, with increasing surface temperature, the time of movement of the fibrous material along the inclined surface decreases, which indicates an increase in the speed of movement due to a decrease in the friction forces between the fibrous material and the surface.
