Abstract

At ginneries, after the ginning process, fibrous material remains on the seeds, the amount of which depends on the selection variety of raw cotton. The current state of lintering of cotton seeds does not satisfy the increased demand of the ginning industry and the cotton-textile cluster. The practice of operating serial 5LP brand linters shows that the actual performance of the 5LP linters is low and averages 50% of the data in the passport The main working body in the lintering process is the working chamber and the saw cylinder. The working chamber is characterized by its shape and size, the position of the agitator, seed comb, grate, etc. The shape of the working chamber is determined mainly by the length of the arc of entry of the saw into the chamber. The place where the seeds are fed to the saws and the allocation of polished seeds from the chamber depends on this. The grate profile has a great influence on the number of allocated pollinating seeds in the interspinous space, on the performance of the linter and the quality of the produced lint and seeds. One of the main working bodies that determine the operability of the linter chamber is the grate. Due to the imperfection of the construction of the grate, in the process of lintering, accumulation of seeds is formed at the exit of the working chamber in the region of the lower frontal beam, which leads to a delay in the exit of seeds from the working chamber. This increases the density of the seed roller and decreases the entry of pubescent seeds into the working chamber, which leads to a decrease in the productivity of the linter. A theoretical study was made of the flow of seeds moving on sections of the grate with a certain speed and decreasing as the flow moves with pressure and density along the grate outline.
