In analytical chemistry are widely used in various mixers, agitators, including apparatus for shaking type AVA-6P (see Equipment for chemical laboratories. The Handbook. - L.: Chemistry, 1978, str, 38 / Mushkin A.P., Rachinsky FU, Suglobov CD)containing a base movably mounted on its tripod, with clamping device, the drive and control unit and temperature control.

The closest analogue of the claimed invention is a device for extraction, presented in the patent RU 2048776, C1, 01 D 11/00, 27.11.1984,

The apparatus has the following disadvantages:

- gravitational separation of the processed mixtures;

- instability of extraction, loss of impurities in samples of 20-40%;

- high consumption of electricity.

The technical problem is solved in that the extractor-separator, comprising a housing, the extraction module and the actuator, characterized in that the apparatus d which contains additional separation module, coaxially fixed in the housing, and the control unit and temperature control, and the extraction module and separator module movably installed on poles in parallel in the vertical plane, the extraction module is made in the form of an annular tripod socket for removable cups, the separation module includes a rotating hollow cylindrical rotor to accommodate removable cups and is equipped with a replaceable collector extract and annular chamber with drain fitting, removable cups made with a separator lid, this group, the actuator provides rotational-vibrational motion of the tripod in the mode of extraction and rotational movement of the rotor in the mode of separation.

Technical solution provides a highly efficient interaction of the processed blends, optimization of the separation process under the action of centrifugal forces and reducing the time for the extraction and separation of the extract from the sample. The intensification of the process of mixing the sample with the solvent provided a uniform volumetric contact the processed phase and with the exception of stagnant zones by imposing on transverse vibrations of centrifugal forces. The use of a separation module allows you to reduce not only the time spent on manual operation of separation of the extract from the sample, but also reduces p is Teri obtained volume of the extract.

Figure 1 shows the schematic design of two-extractor-separator with parallel placement of extraction and separation units, figure 2 - coaxial their location. Figure 3 presents the design of the rotor with the rotating annular chamber, and a replaceable collections of extract for each replacement glass installed coaxially to the rotor.

Extractor-separator (figure 1) consists of a housing 1, which is placed on supports extraction module in the form of a slidably fixed tripod ring 2 and the separation module 3 with lids 4 and 5, respectively. Removable cups 6 with a separator lid 7 is placed in the socket of the tripod with the possibility of fluctuation relative to the tripod 2. Tripod 2 is mounted on a shaft 8 of the bearing unit 9. The drive 1 equipped with the oscillatory mechanism 10 for rotationally oscillating motion of the tripod 2, and the switching clutch 11. The separation module 3 is made in the form of a hollow rotating cylindrical rotor 12, the shaft 13 and the bearing unit 14. The internal cavity of the rotor is designed to contain a removable cups 6 with the separation of the cover 7. The rotor 12 is equipped with non-rotating annular chamber (manifold) 15 with drain fitting 16 and a removable collection of extract 17. Figure 2 presents accommodation separation of mo is Ulya axis of rotation of the ring tripod, i.e. tripod is coaxial rotor separation module, and the tripod is in the lower part 24 of the housing 1, and the separation module occupies the upper part 23, which is chosen device made in the form of a rotating annular chamber 15 and the fixed Adonai tube 25 and a removable collector extract 17. Extractor-separator temperature-controlled, heated tripod 2 and the separation unit is a fan heater 18. To increase the intensity of the extraction process in the apparatus (figure 2) provides a mechanism for giving removable glasses additionally fluctuations relative to the tripod in the radial direction, for example, in the form of a Cam mechanism comprising fixedly mounted on the housing of the disk 19 with rollers 20 for each removable cups.

Primary execution unit without a Cam mechanism.

Figure 3 presents the design of the apparatus when the rotor is constructed with the possibility of installing it coaxially of one or more removable cups, and in the annular chamber is placed a corresponding number of replacement collections extract with fixing the drain hole 26 in the separation of the cover relative to the collection of the extract 17. Ring the camera provides in this case the rotation of the removable collections of the extract together with the rotor separation of mo is Ulya.

Extractor-separator (figure 1) works as follows.

Removable cups filled with samples and pour solvent in predetermined amounts and proportions of phases in accordance with the method of analysis, close separation cover and set in sockets of rolling tripod and close the lid. Include the drive tripod, and there is intense mixing in the whole volume of the sample without stagnant zones at the expense of the rotational-vibrational motion of the tripod, i.e. fluctuations tripod circumference and vibration removable cups in the radial direction of the tripod, get glasses when they come in contact with the roller Cam mechanism. When moving around the circumference of the removable cups in contact with the rollers and are rejected on the vertical axis, and passing through the roller, the Cup oscillates under the action of its own weight, and thus removable glasses subject to the following motion: rotational and vibrational in the direction of the circumference of the tripod and vibrational - radius tripod. The amplitude and frequency of oscillations are electronic block.

In case of carrying out the extraction at elevated temperatures include the block temperature. Time is the reference time on the remote control, which automatically disables the device. Upon completion of the extraction remove cu is the Cabinet tripod, take out removable cups of tripod and alternately installed in the rotor of a separation module for separating the extract from the sample. Switch clutch and include the drive rotor. Under the action of centrifugal force separates the extract from the solid phase. The solid phase as a more heavy pressed against the inner surface of the removable Cup, and the liquid phase is discharged into the separating cover through cracks and holes and gets inside it, through the hole where the separation of the cover merges into an annular chamber, then through the drain fitting is adjudged to be in an interchangeable collection of the extract. Figure 2 shows a variant of the selection of the extract using Adonai tube. The device is similar.

Figure 3 illustrates the case of simultaneous selection of the liquid phase from all removable cups. In this case, carrying out extraction similar to the first occasion, then after the extraction, the actuator switch on the rotation of the rotor with annular chamber and replaceable collections of the extract. Under the action of centrifugal forces in a solid sample is pressed against the peripheral (relative to the rotor axis) parts replacement glasses, liquid phase through holes and cracks fall into the internal cavity of the separation of the cover, where through the drain hole falls into a removable collection of the extract, which is set so that when the rotation is Sri liquid was poured. After a predetermined time the device is switched off automatically. Open the lid, take out the removable glasses, then take out the removable collections extract and pass on further work in accordance with the method. Installing a new set of replacement glasses and collections extract and close the lid. The instrument is ready for operation. The cycle repeats.

Lightweight extraction of drum and submission of the rotational-vibrational motion to the periphery of the drum simplify the design of the drive and significantly reduce power consumption:

Testing of this design in the methods of analysis in the system of ecological monitoring, veterinary and plant protection have shown high efficiency of the extractor: the increase in the percentage extraction of up to 20% and decrease extraction time of 40 min to 30 min and manual separation with 6 min to automatically up to 30 seconds.
