Abstract Since cotton cleaning in Uzbekistan is carried out mainly manually, this paper discusses the methods and technologies established in the process of cleaning cotton and fiber. The process of fiber cleaning is one of the important processes that complete the technological process of cotton processing, given that the quality of fiber largely depends on the efficiency of this process, the research work on the mechanization of the type of collection and improving the efficiency of its cleaning is analyzed. In order to improve the efficiency of cleaning cotton collected on the machine, information is provided on the need to improve the equipment for cleaning fiber used in cotton gins. The research results are based on the need to replace a special structural device that guides the fiber to the correct tooth of the first sawtooth cylinder located on two drum cleaning plants. New fiber-cleaning equipment was installed in the Jizzakh regional JSC “Zarbdor cotton cleaning» and experimental tests were conducted in production conditions. In addition, the process of changing the pressure, density and speeds in the furnace and the effect of their cleaning efficiency has been modeled and theoretically analyzed, when the efficiency of cleaning the cotton fiber flow using a column system allows changing the raw material from 4 mm to 15 mm based on the device. By results of the conducted analysis it was shown that the increase of efficiency of purification depends on the device attached to the saw teeth, factor of the taxation of the distribution coefficient B and p 0 efficiency factor of increasing the initial pressure and coefficient of efficiency savings from the analysis of graphs, which present graphs of the distribution depending on the type of saw teeth. Based on the results of the research, recommendations are given for the widespread introduction of fiber cleaning equipment installed at enterprises of primary cotton processing, with the installation of a special structural guide device.

This study aims to solve existing problems in cleaning medical devices, such as the cumbersome loading of minimally invasive surgical instruments, the incomplete cleaning of instruments with complex structures, and the low cleaning efficiency of ordinary instruments. A pulsating vacuum cleaning machine was combined with ultrasonic cleaning and boiling cleaning technology to clean various complex medical devices through a pressure pulsating process (i.e., repetitive pump-out and pumpin until the cleaning results meet the cleaning standards for medical devices). The cleaning results of spay washing, ultrasound cleaning and pulsating vacuum cleaning were compared among four groups of medical devices, including silica gel hoses, chamber instruments, whole box of minimally invasive instruments and surgical instruments. The amount of protein residues was tested using the spectrophotometric method. The testing results revealed that the loading capacity of a pulsating vacuum cleaning machine is 3–4 times as much as that of an ordinary spray cleaning machine, without manual placement and connection operation required, which reduced the workload of pretreatment. The protein residue after cleaning meets the requirements of the YY/T0734 standard for the cleaning effect of medical devices. Pulsating vacuum cleaning technology has an overall better loading capacity, when compared to spay washing and ultrasound cleaning, and this can make up for the shortcomings of commonly used cleaning machines, such as the low cleaning efficiency and unsatisfactory cleaning results of medical devices with complex structures.

Abstract This article analyzes the importance of the process of ginning cotton with high pollution before ginning, the operation of the ginning device before ginning, the impact of the device nodes with the raw cotton. At the same time, the cleaning efficiency of the machine in the cleaning equipment from small and large contaminants, the basic control developments and calculation processes in the selection of the technological parameters of the cleaners are considered. It was suggested and analyzed that before the cotton was ginned, the cleaning device should be replaced with cone-tipped piles and a new belt extension to remove impurities instead of fine-grained drum piles. The impact strength and impact of the proposed conical-tipped pile drums on cotton have been studied.

Household Cleaning

The characteristics of traditional vacuum cleaner and automatic cleaning robot are analyzed in the paper. A new device for household cleaning is designed. The device combines leaning mechanism with suction mechanism. It could work only by pushing the cleaning machine. In its working process, the cleaning mechanism cleans larger litters first, and then the acceleration mechanism drives the impeller rotating at a high speed, and thus produces negative pressure to inhale the remaining dust. The device could improve cleaning efficiency. As the dust suction mechanism only needs to inhale dust, the force could be smaller .It will saves power and reduces the noise generated by the vacuum part at the same time.

Measurement Results

The measurement results of acoustic field parameters above electroplating bath, in presence of water vapour, are analyzed in this work. Suction was created by means of side exhausters. It is obtained that the sound field generator generated a sound level of 130–140 dB at frequency interval between 1 and 10 kHz. It is shown that aerosol coagulation and precipitation processes are intensified under the mentioned conditions. The concentration of vapour and other aerosols in removal air decreases as a result, therefore air cleaning equipment costs can be reduced and cleaning efficiency increased.

Abstract To obtain high-quality grain and seeds, it is necessary to clean the combine heap of weeds. Modern air-screen grain cleaners equipped with a screen cleaning systems, flat screens and a double-aspiration pneumatic system with pre-screen and post-screen cleaning channels are used. The fractional principle of post-harvest grain processing is promising. To create a universal grain cleaning machine to isolate the main fraction from the grain heap at the first stage of post-harvest processing, Voronezh State Agar University named after Emperor Peter I carried out theoretical and experimental studies, which made it possible to develop OZF-50, OZF-80 and SVS-30 separators. The machines have higher productivity, the original sieve design with an increased share of sorting sieves and an exclusive aspiration system. A number of new technical solutions have been used in the design of the separators, protected by patents of the Russian Federation. Theoretical prerequisites established the possibility of increasing the productivity 1.6-1.8 times according to GOST R 52325-2005. The total air consumption of the pneumatic system of grain cleaning machines can be reduced by 25-40%. Further improvement of separators requires a deeper study of the grain fractionation process, aerodynamic characteristics of aspiration systems, receiving and distribution devices, and establishment of close mutually beneficial relations between scientific institutions and agricultural engineering enterprises. This can contribute to the development of both domestic agricultural science and grain cleaning equipment production.

Abstract The article examines the dependence of the speed of rotation of the spiked cylinder of the machine for cleaning the raw cotton from fine impurities on the cleaning efficiency of the machine by different varieties. In addition, the article plotted the speed of rotation of the spiked cylinder as a function of mechanical damage to the seed. Based on experimental studies, the operation of the machine for cleaning cotton raw materials from fine contaminants is based. Experimental studies on raw cotton of medium and fine fiber varieties of hand and machine cotton picking on the value of constant and differentiated peripheral speeds of cylinders fully confirmed the theoretical conclusions. It is recommended to use a differentiated high-speed mode of rotation of the spiked cylinders: When cleaning medium-staple cotton - 10:11:12 m/sec, when cleaning fine-stapled cotton - 9:10:11 m/sec.
