VIBRATION TECHNOLOGY WITH A LARGE AMPLITUDE OF PARTICLE MOTION OF FEED COMPONENTS

abstract 1071503118 issue 107 pp. 1807 – 1824 31.03.2015 ru 795
The article has revealed the contradiction between the way of technological impact and the means of implementation of technological transport in existing processes of feed preparation. There has been shown the possibility of eliminating this contradiction by menus of completely new technological equipment on the basis of relative screw drums and the opportunity to improve their productivity. There are no exciters in the offered design of vibrating machines. There is no need for them because the move mend of mass loading particles is provided by the original constructions of relative screw drums committing a rotary motion around its own axis. For implementing of feed preparation process the geometry of the relative screw drum and its dynamism must be individual: the shape, spatial orientation, the impact of forces providing feed components particles simultaneously with rotational-translational and vibrational motion. In the result, the continuously running through the inner cavity of the relative screw drum particles of feed components perform rotational-translational movements with super imposed vibrations inside this drum, due to this process the particles of feed components are mixed intensively

RESEARCHING AND CREATION OF A DEVICE FOR DRYING CHICKEN MANURE

abstract 1071503117 issue 107 pp. 1794 – 1806 31.03.2015 ru 882
In this article the authors have proposed a process and arrangement for recycling in the poultry farms of the Krasnodar region of chicken manure and release of mineral fertilizers, аs well as the analysis of existing Russian technologies and devices for drying chicken manure. The study proposed a technology and apparatus for drying chicken manure to not only provide a significant deal of capital investments, but also cut energy costs by the proposed method and apparatus, as well as improving the quality of the finished product (chicken manure). In the method of drying chicken droppings produced removing mechanical impurities, mixing, drying and grinding of the hot gases, wherein the starting slurry is transported in a horizontal direction opposite to the flow direction of the hot gases while performing a gradual heating it with simultaneous comminution and mixing, and then after reaching the zone of maximum temperatures for each of the size fractions of the suspension is achieved by turning its direction on 180ºÐ¡ and then transported in a direction coinciding with the direction of flow of the hot gases by carrying out the gradual cooling of the heat transfer starting product. We have also presented norms of dry chicken manure application under agricultural crops in the Krasnodar region

MULTIMEDIA TECHNOLOGIES FOR TRAINING FOR "DESCRIPTIVE GEOMETRY AND ENGINEERING GRAPHICS" COURSE FOR STUDENTS OF THE FACULTY OF CIVIL ENGINEERING IN KUBGAU

abstract 1071503116 issue 107 pp. 1780 – 1793 31.03.2015 ru 989
The article examines the teaching descriptive geometry and engineering graphics on Faculty of Civil Engineering, higher-motivation of students to obtain needed competence to adopt competently compensation-drawings. The article describes the basic methods of conducting classes on the subject "Descriptive Geometry and Engineering Graphics" for students enrolled in the specialty 08.05.01 "Construction of unique buildings and structures." For lectures and laboratory classes in the department of descriptive geometry and graphics were developed multimedia courses with animation for all studied subjects, educational presentations that reveal the specifics of the discipline into account peculiarities of the educational process of learning in the Kuban State Agricultural university. Multimedia courses using enables us to model a situation that forces students to analyze, compare the solves of the task. Students develop an algorithmic way of thinking, formed the ability to think and act optimally variability. The use of multimedia development at the Department of Descriptive Geometry and Graphics showed an increase of performance results compared to the previous years of employment without presentation. It indicates that the use of multimedia lectures and laboratory exercises improves the efficiency and quality of education, as well as gives an opportunity to a greater extent to explain the learning material for students

DEVELOPMENT AND CALCULATION OF STRUCTURES OF A HEAT EXCHANGER

abstract 1241610087 issue 124 pp. 1342 – 1352 30.12.2016 ru 274
There are the results of the research on creating a heat exchanger. It is based on the experience of creating equipment for swirling of liquid and gas flows and changing of their directions, their whirling, leading to destruction of the boundary layer on heat-transfer surfaces and intensification of heat-exchange processes. Screw rotors are suggested as working bodies of the heat exchanger. Each flow-cross section in them differs from the previous not only by its form but also by its location relative to each other. With that, the cross-section area changes, the medium motion stationary breaks, the intensity of heatexchange processes increases, technological capabilities enhance. Screw rotors are supplied with laps created on exterior surfaces of rotors during their assembling and allowing intensification of heatexchange processes. Dependencies for calculating of screw rotors basic characteristics are presented in the work. Screw rotors provided with helical grooves on the inner surface with a spiral lines on the outer surface of different pitch and number of visits. The work is done on the basis of research carried out at the Kuban state agrarian University on the use of helical rotors in industry, construction and agriculture [1-23]

CONSTRUCTION AND CALCULATIONS FOR DEVICES FOR DRYING CHICKEN MANURE

abstract 1341710085 issue 134 pp. 1046 – 1054 29.12.2017 ru 377
The article presents innovative technologies and developed methods and devices for drying chicken manure. Ways of their optimization on the basis of screw aggregates and a calculation technique for introduction in production are offered. The results of a long-term research into the search for and development of innovative technologies for the construction of a methodology for calculating not only a device for drying chicken manure with subsequent introduction into production, but also a device for drying bulk materials of agricultural purpose are shown. An example of thermal calculation and selection of the parameters of a drying device is shown on the basis of screw aggregates
