Изобретение относитс к области термического анализа и может использоватьс , в частности, в технике отделени паров элементов геологических проб, например ртути.The invention relates to the field of thermal analysis and can be used, in particular, in the technique of separating vapors of elements of geological samples, such as mercury.

Известно устройство дл термического анализа проб, состо щее из горизонтально расположеннсй цилиндрической нагревательной печи, внутри которш соосно установлен держатель с реакщонными сосудами, привод дл вращени держател и средство дл измерени разнищ 1 температур 1 .A device for thermal analysis of samples is known, consisting of a horizontally arranged cylindrical heating furnace, inside which there is a coaxially mounted holder with reactant vessels, an actuator for rotating the holder, and means for measuring the difference 1 of temperature 1.

Однако конфигураци реЕЖционного сосуда не обеспечивает полноценного термического анализа пробы; устройство рассчитано только на определение разницы температур испытьшаемого и эталонного сосудов.However, the configuration of the retention vessel does not provide a complete thermal analysis of the sample; the device is designed only to determine the temperature difference between test and reference vessels.

Цель изобретени - повысить точность анализа.The purpose of the invention is to improve the analysis accuracy.

Это достигаетс благодар тому, что держатель вьшолнен в виде двух вертикально установленных неподвижных дисков с пазами по окру { ности дисков , привод - в виде двух вращаюи хс дисков, вертикально установленных на валу, ось которого совпадает с осью неподвижных дисков, а каждый из реакционных сосудов - в виде двух соединенных между собой частей разных радиусов: цилиндрической и шарообразной, причем торцовые кромки This is achieved due to the fact that the holder is made in the form of two vertically mounted fixed disks with grooves around the disks, the drive is in the form of two rotating disks mounted vertically on the shaft, the axis of which coincides with the axis of the fixed disks, and each of the reaction vessels - in the form of two interconnected parts of different radii: cylindrical and spherical, with the end edges

вращающихс дисков соприкасаютс с цилиндрической частью трубок, а их шарообразна часть входит в нагревательную печь.the rotating discs contact the cylindrical part of the tubes, and their spherical part enters the heating furnace.

На фиг. 1 показана цилиндрическа печь, вид в плане с частичным разрезом; на фиг. 2 - вид по А-А.FIG. 1 shows a cylindrical furnace, a plan view with a partial cut; in fig. 2 - view A-A.

Привод устршства имеет диски 1 и 2 с резино-. выми кольцами 3, закреплешп 1ми на валу двигател 4, ось которого совпадает с осью неподвижного диска 5 с расположенными по кругу пазами 6 и пружинными зажимами и осью неподвижного направл ющего диски 7, имеющего по кругу пазы 8.The drive has discs 1 and 2 with rubber. rings 3, fasteners 1m on the motor shaft 4, the axis of which coincides with the axis of the fixed disk 5 with grooves 6 arranged in a circle and spring clips and the axis of the fixed guide disks 7 having a groove 8 in a circle.

Резиновые кольца 3 уложены в канавку, проточенную по центру дисков 1 и 2, и служат дл фрикцио шого взаимодействи с трубками 9 и шарообразными кошими.Rubber rings 3 are laid in a groove machined through the center of disks 1 and 2, and serve for friction interaction with tubes 9 and spherical koshimi.

Пружинные зажимы представл ют собой винты 10 и держатели И, которые с помощью пружины 12. надетой на винт 10, удерживают в пазах 6 трубки 9.The spring clips are screws 10 and holders I, which with the help of a spring 12. Put on a screw 10, hold tube 9 in the grooves 6.

Claims

The tube 9 with its sharpened end has four points of support: two on the rubber rings 3 rotating discs 1 and 2, and in the groove 6 of the fixed disk 5 and one in the groove 8 of the fixed guide disc 7. The tubes 9 are held in the groove 6 with the holders 11. The fixed disk 7 has a heat shield 13 and apertures 8, the axes of which are coaxial with the grooves 6 on the stationary face 5. The heating elements are arranged in a circumference in the form of a helix 14 mounted into the internal heat shield 15 of the heating furnace 16. The furnace has a switch 17 and adjusting ruler 18. The device operates as follows. The theological sample being analyzed is poured into the spherical part of the glass tube 9, which is installed in the grooves 6 of the non-mobile disk 5 and the grooves 8 of the fixed nagfull disk 7. The tubes 9, which are in the grooves 6 and 8, are simultaneously simultaneously at two points touch the rubber rings 3 discs 1 and

2. The tubes in the slots are held by holders 11. Engine 4 is turned on, and discs 1 and 2 with rubber rings begin to rotate (at a speed of 2.5 rpm). Tubes 9, in contact with the rubber rings 3, also wrap. The spherical ends of the tubes with the sample, which are located in them in an ordinary pike 16 inside the spirals 14 encircling them, rotate and evenly pour the sample. The spherical ends of the tubes 9 with the sample, being in the furnace 16, are simultaneously subjected to rotation along the entire spherical surface. ilpoSa, fuzzy, emit mercury vapor, which, when submerged, precipitates m cylindrical cold part of the tubes. Sample heating (sublimation) is carried out 1,5-, mi (. Naphta tube 9 is taken out of the grooves 6 and 8, and a new tube is set in them. Removing and installing the tube at a non-stop rotation) yes (disks I and 1). Turning on and off the furnace by means of a switch 17. The water heating temperature is regulated by the regulating ruler 18, i.e. reMTiepaiypa heating of the sample depends on or the distance between the P1A-shaped part of the ipjijKK P and the 1P1P1 oven with a baking oven 16. The invention The device for thermal ana / specimen testing, consisting of a horizontal cylindrical naphtha furnace, inside which is mounted a holder with reaction vessels, a holder for holding and means for measuring the temperature differences, characterized in that, in order to increase the point of analysis, the holder is made in the form of two vertically mounted fixed dogs with grooves around the circumference The drive is in the form of two rotating discs, vertically mounted on a shaft, the axis of which coincides with the axis of the fixed wheels, and each. from recurring vessels - in the form of two parts of different radii connected between one's own: cylindrical and spherical, with the end edges rotating (their disks come into contact with the cyanthric part of the tubes, and their shara-like part is fed into the heating furnace.
