Description

[0001] The utility model relates to the field of roller tables used for rotating closed cylindrical containers around their longitudinal axis of rotation, and can be used for mixing or stirring substances (gases and / or liquids) inside cylindrical containers placed and rotated on the table.

[0002] Hereinafter, the terms "rotating table for cylindrical containers" and "table" are used interchangeably.

[0003] A device for mixing liquids is known (patent for utility model RU 86115 U1, published on 27.08.2009), comprising a housing with a pair of rollers with a drive located therein, the housing is designed as a table equipped in the lower part with roller supports with brakes, on the upper plane (table top) of which a pair of rollers are mounted parallel to each other, one of which is connected to a drive, and the other is idler, wherein the roller with the drive is covered with a friction material, and the idler roller is mounted with the possibility of fixed movement relative to the roller with the drive, wherein the drive is made adjustable in the number of revolutions and is equipped with a timer. The table top has no inclination to the horizontal plane.

[0004] The disadvantage of the device is the increased energy consumption when rotating cylindrical containers.

[0005] A table for rotating cylindrical containers is known (https: / / www.lronning.com / products / mixing-roller-for-gas-cylinders-m264-000-xxx?variant=34282125918345%2C date of saving according to the website

[0006] https: / / web.archive.org / web / 20250603073052 / https: / / www.lronning.com / products / mixing-roller-for-gas-cylinders-m264-000-xxx?variant=34282125918345-03.06.2025), selected as a prototype and containing an electric motor, to the rotor of which a shaft is attached, with rollers fixed to it, and four more shafts with rollers are installed parallel to this shaft. All shafts are fixed on two longitudinal supports attached to a rectangular frame, which also functions as a table top. The rectangular frame is designed to rotate around its axis of rotation using a hydraulic drive. The rectangular frame is provided with a stiffener placed parallel to the shafts. The cylindrical containers subjected to rotation are initially placed vertically on the end platform of the frame. When turning the frame (i.e.(when the frame rotates around its axis of rotation), its end surface also functions as a fence, preventing possible displacement of rotating cylindrical containers in the direction of the frame tilt.

[0007] The description of the prototype does not disclose the possibility of rotating cylindrical containers around their axis of rotation when the frame is positioned at an angle to the horizontal plane, however, if such a possibility exists, then the substances being mixed in cylindrical containers placed at an angle to the horizontal plane and rotating around their axis of rotation are mixed more intensively, which leads to a decrease in the energy consumption of the table due to the acceleration of the mixing process.

[0008] The disadvantage of the prototype is the increased consumption of electricity required for rotation (turning) of the frame around the axis of rotation of the frame using a hydraulic drive, as well as for compensating for the friction that occurs between the bottoms of the cylindrical containers and the end surface of the frame, when rotating cylindrical containers filled with substances during their mixing.

[0009] A technical problem of the prior art is the increased energy consumption of the table when mixing substances in cylindrical containers.

[0010] The technical result is a reduction in the energy consumption of the table when mixing substances in cylindrical containers.

[0011] The technical result is achieved by a table for rotating cylindrical containers, including a tabletop mounted on legs and having a fixed inclination relative to the horizontal plane. Rollers, one of which is the drive roller, are mounted on the tabletop. The rollers are attached to brackets and are capable of rotation around their axis of rotation. The drive roller is connected to a rotary drive, which allows the drive roller to rotate around the axis of rotation of the drive roller. The rollers are arranged in rows, with the axes of rotation of the rollers in each row aligned.

[0012] It is advisable to mount the rollers on the roller rotation axes on bearings.

[0013] It is permissible for the rollers to have a coating with a high coefficient of adhesion.

[0014] It is permissible for the tabletop to have a stop unit mounted along the end of its lower edge and containing a pressure roller located above the surface of the tabletop; it is advisable to mount the pressure roller on the axis of rotation of the pressure roller on a bearing.

[0015] The tabletop, with a fixed inclination relative to the horizontal plane, is positioned at an angle (inclination) to the horizontal plane, enabling more efficient mixing of gas and liquid mixtures. The tabletop inclination ensures asymmetrical movement of gas mixtures or liquid mixtures within the cylindrical container during its rotation, creating a more efficient uneven vortex flow for mixing and reducing the homogenization time of gas mixtures or liquid mixtures in cylindrical containers rotating on rollers attached to the tabletop. This reduces the energy consumption of the tabletop when mixing substances (gas mixtures or liquid mixtures) in cylindrical containers.

[0016] A table with a tabletop tilted to a fixed horizontal plane reduces energy consumption when mixing gas or liquid mixtures. All energy consumed by the tabletop is expended solely on the rotary drive, which performs the primary mixing function. Since the tabletop design eliminates the need for a tabletop rotation mechanism with an energy-intensive hydraulic drive, energy consumption for the auxiliary and unproductive function of tilting (rotating) the tabletop is eliminated, significantly reducing energy consumption per cycle.

[0017] Rollers mounted on the axes of rotation of rollers on bearings (for example, sliding or rolling) provide a reduction in the energy consumption of the table when mixing substances in cylindrical containers due to the fact that the bearings provide a reduction in friction between the roller and the axis of its rotation, which allows the roller to rotate with minimal resistance and loss of torque transmitted to the roller through contact with the cylindrical container rotated by the drive roller kinematically connected to the rotation drive.

[0018] Rollers with a high-friction coating reduce table energy consumption when mixing substances in cylindrical containers. This increases the efficiency of torque transfer between the rollers and the cylindrical containers, minimizing torque losses that can occur on the surfaces of the cylindrical containers and rollers when they slip relative to each other (friction loss) during rotation. Using rollers with a high-friction coating on their rolling surfaces reduces the likelihood of slippage, ensuring constant torque.

[0019] A tabletop with a thrust assembly mounted along the end of its lower edge and containing a pressure roller positioned above the tabletop surface and capable of rotation around its axis of rotation reduces the tabletop's energy consumption when mixing substances in cylindrical containers. The thrust assembly allows the tabletop's tilt angle to be increased to critical values ​​(e.g., 75°). Furthermore, the greater the tilt angle, the greater the potential for creating uneven, swirling flows of liquids or gases within the cylindrical container during its rotation, resulting in more intensive mixing and reduced homogenization time for liquids or gases in cylindrical containers rotating on rollers attached to the tabletop.The pressure roller of the thrust assembly prevents movement of a cylindrical container with a tapered bottom along the tabletop axis in the direction of its inclination, acting as a stop in the area of ​​the tapering of the cylindrical containers' tapered bottoms. The pressure roller, driven by the cylindrical container, rotates around its axis of rotation (at a large tabletop inclination angle to the horizontal plane, there is a high risk of the cylindrical container falling off the tabletop without a thrust assembly, making mixing of substances in cylindrical containers impossible. The prototype is equipped with an end plate against which the cylindrical containers rest; the resulting friction between the bottoms of the cylindrical containers and the end plate of the frame leads to increased energy consumption).

[0020] If the thrust unit contains a pressure roller mounted on the axis of rotation of the pressure roller on a bearing (for example, sliding or rolling), this ensures a reduction in the energy consumption of the table when mixing substances in cylindrical containers, since the bearing ensures a reduction in friction between the pressure roller and the axis of its rotation, which allows the pressure roller to rotate with minimal resistance and loss of torque transmitted to the pressure roller through contact with the cylindrical container rotated by the drive roller kinematically connected to the rotation drive.

[0021] The technical solution is presented in figures that do not limit the essence of the technical solution, where:

[0022] Figure 1 shows the front view;

[0023] Figure 2 shows a general view from the top rear left.

[0024] The following positions are shown in Fig. 1, 2:

[0025] 1 - table top (Fig. 1, 2);

[0026] 2 - leg (Fig. 1, 2);

[0027] 3 - roller (Fig. 1, 2);

[0028] 4 - drive roller (Fig. 2);

[0029] 5 - bracket (Fig. 1, 2);

[0030] 6 - rotation drive (Fig. 1);

[0031] 7 - rotation drive control unit (Fig. 1).

[0032] A table for rotating cylindrical containers includes a tabletop 1 mounted on legs 2. Tabletop 1 has a fixed inclination relative to the horizontal plane. Rollers 3 are fixed to tabletop 1, one of which is a drive roller 4. Rollers 3 are attached to brackets 5 so as to be able to rotate about their axis of rotation. Drive roller 4 is connected to a rotation drive 6, configured to rotate drive roller 4 about the axis of rotation of drive roller 4. All rollers 3 are arranged in rows, and the axes of rotation of rollers 3 in each row coincide.

[0033] Tabletop 1 may be solid (i.e., continuous, as shown in Figs. 1 and 2) or in the form of a lattice, or a solid-filled panel, or a cellular honeycomb structure, or a grate, a perforated or slot-bearing sheet, or pipes fastened together, or beams fastened together, or rails fastened together. Profiles of any cross-sectional shape may be used in tabletop 1, for example, rolled T-beams, I-beams, channels, angles, as well as plates (with stiffening ribs), or combinations of these elements. The table top 1 may have stiffening ribs, which are, for example, plates, bulges, rods, tubes, made integral with the table top 1 (for example, cast / milled from a single metal blank) or attached to it (for example, by welding, rivets or screw connection).The table top 1 may comprise one part (for example, one sheet of metal, wherein the sheet of metal may have bent edges) or several parts connected by a threaded connection or by means of welding / rivets / grooves and protrusions, etc.

[0034] The tabletop 1 has a fixed inclination to the horizontal plane when the table is placed on a flat horizontal support surface (the term "support" here refers to a presumably solid surface on which the table can be placed, and which is, for example, concrete, a metal floor, wood, tiles, linoleum, a self-leveling floor, a polymer concrete floor, a brick floor, etc.). The constant fixed inclination of the tabletop 1 to the horizontal plane is ensured by rigid fixation on the legs 2, which have different lengths, while the angle of inclination of the plane of the tabletop 1 to the horizontal plane coincides with the angle of inclination of the axes of rotation of the rollers 3 to the horizontal plane. The angle of inclination of the tabletop 1 to the horizontal plane can be in the range from 5 ° to 75 °, for example, 5 °, 15 °, 25 °, 35 °, 45 °, 55 °, 65 °, 75 °.Thus, tabletop 1 has a lower edge and an upper edge, with the lower edge mounted on shorter legs and the upper edge mounted on longer legs. Tabletop 1 has a fixed inclination relative to the horizontal plane, and this inclination remains constant.

[0035] The table top 1 can be mounted on the legs 2 by means of a threaded connection containing threaded fasteners (screws, bolts), and is designed to be detachable from the legs 2. The table top 1 can be mounted on the legs 2 by means of electric arc welding, or by means of rivets, or soldering, or magnetic connection.

[0036] The table top 1 may have a stop unit (shown in Fig. 1, 2, but not designated by a position), mounted along the end of its lower edge (i.e. perpendicular to the direction of inclination of the table top 1 to the horizontal plane) and containing a pressure roller (shown in Fig. 1, 2, but not designated by a position), located above the surface of the table top 1. The pressure roller may be mounted on the axis of rotation of the pressure roller on a sliding or rolling bearing (not shown in Fig. 1, 2). There may be one or more pressure rollers (for example, five, as shown in Fig. 1, 2).

[0037] Legs 2 may be solid, telescopic, or composite. Legs 2 may be profiles of any cross-sectional shape, such as rolled T-beams, I-beams, channels, angles, as well as plates (with stiffening ribs), or combinations of these elements. A table may have a varying number of legs 2, such as three, four, five, six, seven, or more. Telescopic legs 2 allow the angle of tabletop 1 relative to the horizontal plane to be varied. The greater the angle of tabletop 1 relative to the horizontal plane, the greater the potential for uneven, vortex-like flows of liquids or gases within the rotating cylindrical container.

[0038] Table top 1 and legs 2 can be made of metal or metal alloy, or composite material, or fiber-reinforced composite material, or plastic, or fiberglass.

[0039] Rollers 3 are fixed to table top 1. Rollers 3 may be made of metal or polymer (rubber, polyurethane, etc.), or metal with a polymer coating. Rollers 3 may be cylindrical wheels or ball bearings fixed to bolts / studs / rods / tubes with the ability to rotate freely around the bolts / studs / rods / tubes or together with the bolts / studs / rods / tubes. Rollers 3 may be mounted (e.g. pressed or welded, or by means of a splined / keyed connection) on the axes of rotation of rollers 3 on bearings (e.g. rolling or sliding). Rollers 3 may be polyurethane outer rings with a bearing pressed inside the ring and an axial sleeve inside the bearing. Rollers 3 may be a cylindrical rotary body with chamfers. Rollers 3 may be such bodies of revolution as a cylinder, ball, disk, etc. Rollers 3 may be cast disks with an axial hole.Rollers 3 may be a homogeneous body made of a wear-resistant material (e.g., wear-resistant steel, tungsten carbide, silicon carbide, high-chromium steel, or high-manganese steel). Rollers 3 are designed to rotate around their axis of rotation relative to tabletop 1. Rollers 3 may have a coating with a high coefficient of adhesion, such as: natural rubber, polyurethane, silicone rubber, Vulkollan, or polyvinyl chloride.

[0040] One roller 3 is the leading roller 4. Rollers 3 are attached to brackets 5 with the possibility of rotation around their axis of rotation.

[0041] Brackets 5 can be made of steel, aluminum or composite materials (eg reinforced polyamide).Bracket 5 may be a U-shaped or L-shaped bracket comprising a base - a plate with fastening holes for fixing to table top 1 (with screws, bolts and nuts); wherein the base of the U-shaped bracket is connected to two sidewalls - plates that may be parallel to each other or not parallel, wherein the sidewalls may be perpendicular to the base or placed to it at an angle (for example, 47° or 82°); the sidewalls have coaxial holes with a fixed axis of rotation of roller 3; the axis of rotation of roller 3 may be a rigidly fixed or rotating shaft passing through the holes in the sidewalls and the internal hole of roller 3; both sidewalls may have equal length, width and thickness or different length, width and thickness; bracket 5 may be one-piece (cast) or composite, for example the base and sidewalls may be connected to each other by means of electric arc welding.

[0042] Thus, the brackets 5 can be made in the form of a U-shaped bracket containing a base and two sidewalls, wherein the base can be secured to the table top 1 by means of a threaded connection containing such threaded fasteners as bolts and / or screws.

[0043] Drive roller 4 is connected to rotary drive 6, wherein drive roller 4 is kinematically linked to rotary drive 6, as they are connected in a kinematic chain via kinematic pairs. Rotational drive 6 is configured to rotate drive roller 4 around the axis of rotation of drive roller 4.

[0044] The driving roller 4 can be connected to the rotary drive 6 by means of a rigid coupling mounted coaxially on the shaft of the rotary drive 6 and the shaft of the driving roller 4. The driving roller 4 can be connected to the rotary drive 6 by means of a belt drive comprising a driving pulley on the shaft of the rotary drive 6, a driven pulley on the axis of the driving roller 4 and a belt tensioned between them. The driving roller 4 can be connected to the rotary drive 6 by means of a chain drive comprising a driving and driven sprocket covered by a chain (roller or toothed). The drive roller 4 can be connected to the rotation drive 6 by means of a toothed (gear) transmission, where the shaft of the rotation drive 6 is provided with a drive gear (bevel or cylindrical), which is in engagement with a driven gear (bevel or cylindrical), rigidly fixed on the axis of the drive roller 4, and the drive roller 4 can be connected to the rotation drive 6 directly through a pair of gears or through a gearbox.The drive roller 4 can be connected to the rotation drive 6 by means of a friction transmission, where the drive roller 4 is designed with the possibility of being driven into rotation from the drive roller of the rotation drive 6 by means of frictional contact of their working surfaces.

[0045] All 3 rollers are arranged in rows, and the axes of rotation of the 3 rollers in each row coincide.

[0046] Each roller 3 (including the drive roller 4) can be made without the possibility of being detached or with the possibility of being detached (for example, by unscrewing the nut from the bolt, which is the axis of rotation of the roller 3, or disconnecting the cotter pins from the threaded stud, which is the axis of rotation of the roller 3, or removing the retaining ring from the annular groove of the rod, which is the axis of rotation of the roller 3) from the bracket 5 for replacing the roller 3.

[0047] The legs 2 can be configured to be attached to the support by screwing, electric arc welding, magnetic attraction, gluing, sewing, suction cups, etc., while the legs 2 can be configured without the ability to be attached to the support; for example, the legs 2 can be configured to be attached to the support by screwing on the end elements of the legs (EEL), which are heel pads with holes into which screws or bolts are rigidly inserted or screwed.

[0048] The rotation drive 6 can be fixed (for example, screwed or attached by means of electric arc welding or by means of rivets) above the table top 1 or under the table top 1, or at the end of the table top 1, or attached to one leg 2 / two legs 2. Thus, the rotation drive 6 can be connected to the table top 1 by means of a threaded connection containing threaded fasteners (screws, bolts), and is designed with the possibility of being disconnected from the table top 1. The rotation drive 6 can be electric (electric motor; shown in Fig. 1) or manual (handle; not shown in Fig.).The electric rotary drive 6 may be connected by means of electric wires to the rotary drive control unit 7, wherein the rotary drive control unit 7 may be configured to enable and disable the rotation of the rotor of the rotary drive 6, as well as to change the speed of rotation of the rotor of the rotary drive 6, as well as to change the direction of rotation of the rotor of the rotary drive 6. The rotary drive control unit 7 may be absent, in which case the electric rotary drive 6 is powered directly from the electrical network or a storage battery (not shown in the figure). The rotary drive control unit 7 may be secured (e.g., screwed or attached by means of electric arc welding, or by means of rivets) above the tabletop 1 or under the tabletop 1, or on the end of the tabletop 1, or attached to one leg 2 / two legs 2.

[0049] The legs 2 can be connected (e.g. screwed or attached by electric arc welding or by rivets) to the side frames (shown in Figs. 1 and 2, but not designated by reference numbers), and each side frame can be connected to two adjacent legs 2, as shown in Figs. 1 and 2. The side frames can be made solid or perforated. The side frames can be profiles of any cross-sectional shape, for example, rolled T-beams, I-beams, channels, angles, as well as plates (with stiffening ribs), or combinations of these elements.

[0050] The side frames may be connected (e.g., by threaded connections, or by electric arc welding, or by rivets) to each other by means of stiffeners. The side frames may be connected (e.g., by threaded connections, or by electric arc welding, or by rivets) to the tabletop 1 by means of stiffeners. The stiffeners may be profiles of any cross-sectional shape, such as rolled T-beams, I-beams, channels, angles, as well as plates (with stiffeners), or combinations of these elements. The side frames and stiffeners may be made of metal or a metal alloy, or a composite material, or a composite material with reinforced fibers, or plastic, or fiberglass.

[0051] The rotation drive 6 and the rotation drive control unit 7 can be secured (for example, by means of a threaded connection or by means of electric arc welding, or by means of rivets or nylon ties) on the upper level of the side rails located near the table top 1 (shown in Fig. 1) or on the lower level of the side rails located near the support when the table is placed on the support.

[0052] The threaded connections of the table top 1 and legs 2, the table top 1 and rotation drive 6, the table top 1 and bracket 5 may be equipped with a washer and / or a spring washer-grover, and / or a lock nut. An anaerobic sealant may be applied to the threaded fasteners of the threaded connections of the table top 1 and legs 2, the table top 1 and rotation drive 6, the table top 1 and bracket 5. Thus, the threaded fasteners can be fixed from self-loosening by means of lock nuts, cotter pins, spring (grover) washers or anaerobic sealants; for example, two nuts can be screwed on a bolt in a row - a main nut and a lock nut. An anaerobic sealant shall be applied to the threaded surface of the threaded fastener, for example, to the threaded surface of a threaded rod; An anaerobic sealant may contain acrylic monomers and oligomers, an initiating system, inhibitors and functional additives (thickeners, plasticizers, dyes, etc.).); Anaterm-6B, ANATERM-17, Anaterm-8, Loctite, fixative No. 3, etc. can be used as an anaerobic sealant.

[0053] The cylindrical container rotating table works and is used as follows.

[0054] The table can be used for mixing or stirring substances (gases and / or liquids) inside cylindrical containers (e.g. cylinders, barrels, bottles, test tubes, etc.; not shown in the figure) placed and rotated on the table.

[0055] Let's take a closer look at the operation of the table when mixing methane CH4 and nitrogen N2.

[0056] One or more cylindrical containers (e.g. cylinders) with a volume of 1 to 20 liters are filled with methane and nitrogen and hermetically sealed.

[0057] If the table top 1 has a stop unit mounted along the end of its lower edge and containing a pressure roller located above the surface of the table top 1 and configured to rotate around its axis of rotation, then this makes it possible to increase the angle of inclination of the table top 1 to the horizontal plane, for example, up to 35°.

[0058] Move the table to the desired location. The table can be attached to the support or not. For example, attach all 2 table legs to the support, for example, by screwing the foot pads with 2 screws to the concrete floor, equipped with countersunk holes for screws inserted into the foot pad holes. The screws are screwed into the concrete floor, firmly pulling the foot pads to the support. If the foot pads are rigidly connected to the legs 2, which, in turn, are rigidly connected to the tabletop 1, then the entire table is rigidly connected to the support.

[0059] One or more sealed filled cylindrical containers of approximately the same diameter are placed on rollers 3 in such a way that rollers 3 of two adjacent rows of rollers 3 touch one cylindrical container (in this case, if the cylindrical container is short, then all rollers 3 of two adjacent rows of rollers 3 will not touch one cylindrical container at the same time, however, at least two rollers 3 from each row of rollers 3 must touch one cylindrical container). Contact of one cylindrical container with one driving roller 4 and the remaining rollers 3 adjacent to it, which are driven, must be ensured, and if there are several cylindrical containers, then the second and subsequent cylindrical containers are placed next to the already installed cylindrical container on adjacent rows of rollers 3; the axis of rotation of each cylindrical container must be parallel to the axis of rotation of the rollers 3 that this cylindrical container touches.If there is a rotation drive control unit 7, the rotation parameters (speed, time, direction of rotation) are set and the rotation drive 6 is turned on; for example, the rotation speed is set to 10-30 rpm, the direction is set, for example, reversible with a change in the direction of rotation every two minutes for more efficient mixing, the time is set to 3-10 minutes.

[0060] When the rotation drive 6 is turned on, depending on how the driving roller 4 is kinematically connected with the rotation drive 6, for example, if by means of a chain transmission, then the rotation drive 6 rotates the driving sprocket, covered by a chain, which, in turn, rotates the driven sprocket, also covered by a chain and attached to the axis of rotation of the driving roller 4. Thus, the driving roller 4 rotates around its axis of rotation and, due to friction between it and the cylindrical container, rotates the latter around its own axis, while the cylindrical container, lying between two rows of rollers 3, sets in rotation the remaining rollers 3, not connected to the rotation drive 6. If several cylindrical containers are placed on the table, then upon contact with the rollers 3, driven by friction of the cylindrical container touching the driving roller 4, these cylindrical containers are also set in rotation around their own axis.

[0061] If the rotation drive 6 is manual and equipped with a handle, then the handle, connected to the drive roller 4, for example, by means of a rigid clutch, is rotated by muscular force.

[0062] The constant rotation of the cylindrical container causes the contents to move within it. Tabletop 1, which has a fixed inclination relative to the horizontal plane, allows for more efficient mixing of methane and nitrogen. The inclination of tabletop 1 ensures asymmetric movement of methane and nitrogen within the cylindrical container during its rotation, creating a more efficient uneven vortex flow for mixing and reducing the homogenization time of the gas mixture. This reduces the energy consumption of the tabletop during methane and nitrogen mixing.

[0063] If the rollers 3 are mounted on the axes of rotation of the rollers 3 on bearings (for example, sliding or rolling), then the bearings provide a reduction in friction between the roller 3 and the axis of its rotation, which allows the roller 3 to rotate with minimal resistance and loss of torque transmitted to the roller 3 through contact with the cylindrical container rotated by the drive roller 4, kinematically connected to the rotation drive 6.

[0064] If rollers 3 have a coating with a high coefficient of adhesion (for example, a polyurethane coating), then this coating ensures constancy (stability) of the torque between rollers 3 and cylindrical containers with minimal friction losses between them.

[0065] If tabletop 1 has a stop assembly mounted along the end of its lower edge and containing a pressure roller positioned above the surface of tabletop 1 and capable of rotation around its axis of rotation, the pressure roller of the stop assembly prevents the movement of a cylindrical container with a tapered bottom along the axis of tabletop 1 in the direction of its inclination, acting as a stop in the area of ​​the tapering bottom of the cylindrical container. The pressure roller, driven by the cylindrical container, rotates around its axis of rotation. If the stop assembly contains multiple pressure rollers, multiple cylindrical containers will rest against their respective pressure rollers.

[0066] If the thrust unit contains a pressure roller mounted on the axis of rotation of the pressure roller on a bearing (for example, sliding or rolling), then the bearing provides a reduction in friction between the pressure roller and the axis of its rotation (for example, a bolt), which allows the pressure roller to rotate with minimal resistance and loss of torque transmitted to the pressure roller through contact with a cylindrical container rotated by the drive roller 4, kinematically connected to the rotation drive 6.

[0067] Examples of practical implementation.

[0068] Example #1.

[0069] A table for rotating cylindrical containers was manufactured (not shown in the figure). The table included a solid tabletop 1 mounted on four legs 2, to which rollers 3 were secured. Tabletop 1 was connected to metal legs 2 by means of a threaded connection containing threaded fasteners and was designed to be detachable from the legs 2. Tabletop 1 had a fixed inclination to the horizontal plane (i.e., it was located at an angle of 30° to the horizontal plane when the table was placed on a flat horizontal support). Tabletop 1 had a square shape in plan and was a single piece - a sheet of metal with flanged edges. One roller 3 was the driving roller 4, and all the other rollers 3 were driven. The driving roller 4 was connected to one driven roller by fixing the driving roller 4 and the driven roller on one axis, which was a metal rod with threaded ends (nuts were screwed onto the threaded ends);the driven roller was attached to bracket 5, which was a metal bracket of approximately L-shaped cross-section, containing a base - a plate with mounting holes, screwed with bolts, nuts and washers to table top 1, and the base was connected by means of electric arc welding with one side - a plate, perpendicular to the base and having a hole for the axis of rotation of the driven roller;the driving roller 4 was attached to the bracket 5, which was a metal bracket of approximately L-shaped cross-section, containing a base - a plate with fastening holes, screwed with bolts with nuts and washers to the table top 1, wherein the base was connected by means of electric arc welding with one sidewall - a plate perpendicular to the base and having an opening for the axis of rotation of the driving roller 4, wherein a driven sprocket was fixed on the axis of rotation of the driving roller 4, covered by a roller chain, covering the driving sprocket, connected to the rotor of the electric motor of the rotation drive 6; thus, the driving roller 4 was connected to the rotation drive 6 by means of a chain transmission containing a driving and driven sprockets, covered by a roller chain, wherein the driven sprocket, covered by a roller chain, was closed, on top, by a metal casing, which was attached with rivets to the sidewall of the bracket.

[0070] Rollers 3 projected above the surface of tabletop 1 and were attached to brackets 5 so as to be able to rotate around their axis of rotation. All rollers 3 were mounted on their axes of rotation at a distance from one another. Leading roller 4 was connected to rotary drive 6, configured to rotate leading roller 4 around the axis of rotation of leading roller 4, with all rollers 3 arranged in rows. The axes of rotation of rollers 3 in each row coincided. A total of 18 rollers 3 were attached to tabletop 1: six rows of rollers 3 with three rollers 3 per row.16 rollers 3 were attached to cast brackets 5 made of steel and representing a U-shaped bracket containing a base - a plate with fastening holes, screwed with bolts with nuts and washers to the table top 1, wherein the base had a convex-concave shape and was made integral with two sidewalls - plates that were parallel to each other and perpendicular to the base; the sidewalls had coaxial holes with a fixed axis of rotation of the roller, which was a rotating bolt passing through the holes in the sidewalls and the internal hole of the roller 3, wherein the bolt had a screwed nut on its end; both sidewalls had the same length, width and thickness, wherein the sidewalls had a convex-concave shape.

[0071] Rollers 3 were metal cylindrical wheels, and rollers 3 had a concave section in the area of ​​the axis of rotation.

[0072] Legs 2 were designed to be attached to the support by screwing. Legs 2 were screwed with KENs, which consisted of brass bearing pads with internally threaded holes. Screws were screwed into the holes and could be screwed in and out. Legs 2 were connected by electric arc welding to the metal side rails and had two levels of height. The side rails, which were located in the upper level of the side rails and near the tabletop 1, were perforated, while the side rails, which were located in the lower level of the side rails and near the bearing pads when the table was placed on the support, were solid.

[0073] The drawer sides, included in the upper level of drawer sides and located near tabletop 1, were connected to legs 2 and were also connected by electric arc welding to tabletop 1 via metal stiffeners. The drawer sides, included in the lower level of drawer sides and located near the heels, were connected to legs 2, and the drawer sides were connected to each other by welding via metal stiffeners, wherein the drawer sides were located transversely relative to tabletop 1, and the stiffeners were located longitudinally relative to tabletop 1, wherein the stiffeners were located away from the contour of tabletop 1 (as well as from the two nearest legs 2). All the drawer sides were located approximately along the contour of tabletop 1. There were four drawer sides in the upper level of drawer sides. There were two drawer sides in the lower level of drawer sides.

[0074] The rotary drive 6 was placed under the tabletop 1 and was connected to it by means of a threaded connection containing threaded fasteners, and was configured to be detachable from the tabletop 1 (the rotary drive 6 was screwed to the tabletop 1 with bolts, nuts and washers). The rotary drive 6 was made electric and contained an electric motor. The electric rotary drive 6 was connected by means of electric wires to the rotary drive control unit 7. The rotary drive control unit 7 was configured to turn on and off the rotation of the rotor of the rotary drive 6. The rotary drive control unit 7 was fixed under the tabletop 1; the housing of the rotary drive control unit 7 was screwed to the side rails included in the upper level of the side rails by means of bolts, nuts and washers.

[0075] The threaded connections of the table top 1 and legs 2, table top 1 and rotation drive 6, table top 1 and brackets 5 were equipped with spring washers.

[0076] We moved the table to the desired location and attached the 2 table legs (and the entire table, respectively, since the table together with the 2 legs was a rigid structure) to the support - the concrete floor, while screwing the screws into the concrete floor, which had blind counter-threaded holes for the screws, firmly pressing the heel pads to the concrete floor.

[0077] Two cylindrical containers of the same diameter and dimensions were filled with gas mixtures containing nitrogen N2 and argon Ar and mounted on rollers 3. Rotation drive 6 was turned on and the cylindrical containers were rotated for five minutes.

[0078] Table top 1, which has a constant fixed inclination to the horizontal plane, made it possible to reduce the homogenization time of gas mixtures, which reduced the energy consumption of the table.

[0079] Example #2.

[0080] A table for rotating cylindrical containers (not shown in the figure) was manufactured. The table included a lattice metal tabletop 1 mounted on three legs 2, to which rollers 3 were attached. Tabletop 1 was connected to the metal legs 2 by electric arc welding. Tabletop 1 had a fixed inclination to the horizontal plane (i.e., it was positioned at an angle of 60° to the horizontal plane when the table was placed on a flat horizontal support). Tabletop 1 had a rectangular shape in plan and consisted of metal channels connected by electric arc welding. One roller 3 served as the driving roller 4, and all the other rollers 3 were driven.

[0081] The driving roller 4 was connected by means of a rigid coupling to a handle, which was a manual rotation drive 6. All the rollers 3 were attached to U-shaped brackets 5 with the ability to rotate about their rotation axis; the brackets 5 were attached to the tabletop 1 by welding. The driving roller 4 was connected to the rotation drive 6, configured to rotate the driving roller 4 about the rotation axis of the driving roller 4, while all the rollers 3 were arranged in rows. The axes of rotation of the rollers 3 in each row coincided. Twelve rollers 3 were fixed on the tabletop 1: three rows of rollers 3 with four rollers 3 per row. The rollers 3 were polyurethane balls with an axial hole with a rolling bearing pressed into it, i.e. the rollers 3 had a high coefficient of adhesion and were mounted on the rotation axes of the rollers 3 on bearings.

[0082] Along the longitudinal edge of tabletop 1, a stop assembly was attached. It contained three vertical metal posts of rectangular cross-section, to which five pressure rollers were attached via plates. Two adjacent posts (the central and outer posts) were equipped with two pressure rollers, and one post (the outer post) was equipped with one pressure roller. The pressure rollers were designed to support cylindrical containers and prevent them from slipping off the table.

[0083] Two of the pillars had plates shaped like isosceles trapezoids with rounded vertices, while the third pillar had a plate shaped like a rectangular trapezoid with rounded vertices. Each plate had a rectangular slot; a screw was screwed into each slot, securing the position of the plate relative to the pillar. Pressure rollers were fixed in the area of ​​the vertices of the plates.

[0084] Each rack had a metal base that was approximately U-shaped in plan, with the base protruding above the surface of tabletop 1 and being screwed with bolts, nuts and washers to tabletop 1. The plane of rotation of the pressure rollers was deviated from the longitudinal plane of the racks, since the plates in their upper part were bent away from the racks.

[0085] Thus, tabletop 1 had a thrust assembly mounted along the end of its lower edge and containing pressure rollers positioned above the surface of tabletop 1 and capable of rotation around their own axis. Each pressure roller was mounted on a rolling bearing on the axis of rotation of the pressure roller.

[0086] Moved the table to the desired location and placed it on the support.

[0087] Two cylindrical containers of identical diameters and dimensions were filled with liquid mixtures containing gasoline and methanol and mounted on rollers 3. Drive handle 6 was rotated using muscle force, causing the cylindrical containers to rotate. A stop assembly, positioned perpendicular to the tilt of tabletop 1, formed a barrier preventing the cylindrical containers from falling off tabletop 1.

[0088] Table top 1, having a constant fixed inclination to the horizontal plane, made it possible to reduce the time for homogenization of liquid mixtures, and the use of a manual rotation drive 6 made it possible to completely eliminate the table’s power consumption.

[0089] Thus, a technical result was achieved - a reduction in the energy consumption of the table when mixing substances in cylindrical containers.
