Description

Technical Field

[0001] The present invention relates to the field of extraction equipment, in particular to a rotary disc extraction tower. Background Art

[0002] The turntable extraction tower is a high-efficiency liquid-liquid extraction equipment based on the principle of mechanical stirring. Its core structure consists of an upper clarification section, a mixing section and a lower clarification section. The mixing section is equipped with a fixed plate to separate the space. The turntable and the fixed plate are staggered. The shear force generated by the rotation of the turntable breaks the dispersed phase liquid into tiny droplets, significantly increasing the interphase contact area and thus improving the mass transfer efficiency. During the rotation of the turntable, the fluid may stagnate in some areas of the fixed plate and the tower wall surface. This area is called the dead zone.

[0003] The reference patent is named: Rotary Disc Extraction Tower and Its Application (Patent Announcement No.: CN111701278B). The fixed plate fixed on the inner wall of the tower body is decomposed into two layers of fixed plate layers, and the two layers of fixed plate layers are staggered. The single layer of fixed plate layer is arc-shaped, and the two layers of fixed plate layers are stacked to form a ring. This reduces the contact area between the single layer of fixed plate layer and the two-phase mixture, avoids the accumulation of particles on the surface of the fixed plate, and avoids short-circuiting of the fluid path.

[0004] However, when implementing the above technical solution, the following problems exist: the fixed plate inside the above turntable extraction tower changes the volume of the dead zone by reducing the area of the single-layer fixed plate layer, but the gap size between the fixed plate layer and the tower wall remains a fixed value, and the flow path of the fluid is increased; when processing complex systems with high viscosity, high interfacial tension or containing solid particles, the gap between the fixed plate and the tower wall may still cause the fluid to stagnate on the surface of the fixed plate due to the low rotation speed of the turntable, forming a dead zone, resulting in a decrease in the renewal rate of the two-phase mass transfer interface; when extracting different two-phase mixtures, the dead zone volume is still difficult to control.

[0005] To this end, the present invention proposes a rotary disc extraction tower. Summary of the Invention

[0030] A plurality of connecting rods 3, each of which is fixedly arranged on the surface of the sealing plate 2, and a plurality of annular plates 4 are detachably connected between the connecting rods 3, two of the annular plates 4 forming a group, the surfaces of the annular plates 4 in the same group being in contact with each other, and the surfaces of the annular plates 4 being in contact with the interior of the tower body 1; a limiting assembly is provided inside the connecting rods 3 for limiting the position of the annular plates 4;

[0031] The annular plate 4 is slidably connected to two push arcs 5, and the two push arcs 5 are arranged in a circular array inside the annular plate 4.

A plurality of drive rods 6 are slidably connected to the interior of the connecting rod 3. The ends of the drive rods 6 are in contact with the push arcs 5. A drive component is provided between the connecting rod 3 and the drive rod 6 for pushing the drive rod 6 to move;

[0032] In summary, the embodiment of the present invention provides a rotary disc extraction tower, comprising a sealing plate 2 detachably arranged at the end of a tower body 1, a plurality of connecting rods 3 are connected to the surface of the sealing plate 2, a plurality of annular plates 4 are slidably arranged by the connecting rods 3, and a limiting assembly is provided between the annular plates 4 and the connecting rods 3, so that the annular plates 4 can be arranged at intervals on the surface of the connecting rods 3, and the surface of the annular plates 4 is in contact with the inner wall of the tower body 1, so that the entire annular plate 4 can be detached from the tower body 1 through the sealing plate 2, and the two annular plates 4 are in contact with each other, and two sliding pushing arcs 5 are provided inside the annular plates 4, and the two pushing arcs 5 are arranged in an annular array inside the annular plates 4, and the pushing arcs 5 inside the two annular plates 4 are staggered, so that after the pushing arcs 5 slide out of the annular plates 4, the pushing arcs 5 at four different positions can form a certain space on the inner wall of the tower body 1, partitioning the space inside the tower body 1, and a driving assembly is provided between the connecting rods 3 and the pushing arcs 5, and the position of the pushing arcs 5 can be adjusted by the driving assembly, so that the position of the pushing arcs 5 can be adjusted according to the material requirements and the speed of the rotary disc inside the tower body 1, thereby changing the volume of the dead zone;

[0033] In some specific embodiments, the limiting assembly includes a limiting ring 7 rotatably set on the surface of the connecting rod 3, an arc-shaped groove is opened at the end of the limiting ring 7, and a limiting rod 8 is slidably connected inside the connecting rod 3.

[0034] In a further embodiment, two limiting grooves 10 are opened on the surface of the connecting rod 3, and the limiting ring 7 is internally threadedly connected to a limiting shaft 11, and the limiting shaft 11 is adapted to the limiting groove 10; the limiting shaft 11 is rotated to cause the limiting shaft 11 to disengage from the limiting groove 10, and the limiting shaft 11 can be pulled to drive the limiting ring 7 to rotate.

[0036] In some specific embodiments, the drive assembly includes a drive column 16 rotatably disposed inside the connecting rod 3, with a plurality of commutators 17 fixedly connected to the end of the drive column 16, two brushes 18 fixedly connected to the inside of the connecting rod 3, the brushes 18 contacting the commutator 17, and a stator 19 fixedly connected to the inside of the connecting rod 3;

[0037] It should be noted that the brush 18 is electrically connected to an external power source. When the brush 18 is energized, the commutator 17 is energized. The stator 19 contains a fixed magnet or electromagnetic coil that is responsible for generating a magnetic field. When the commutator 17 is energized, the magnetic field is generated. The continuously changing magnetic field causes the drive column 16 to rotate.

[0038] The driving column 16 has a spiral groove 20 on its surface, and the driving rod 6 is fixedly connected with a driving column 21 inside, and the driving column 21 is adapted to the spiral groove 20;

[0039] In a further embodiment, the surfaces of the driving rod 6 and the pushing arc 5 are fixedly connected to a moving column 22, and the connecting rod 3 and the annular plate 4 are provided with a moving groove 23, and the moving column 22 is adapted to the moving groove 23; the moving column 22 and the moving groove 23 limit the radial movement of the driving rod 6 and the pushing arc 5, and the rotation of the driving column 16 can drive the driving rod 6 to slide, thereby realizing the sliding of the pushing arc 5;

[0040] In some specific embodiments, a plurality of fitting rods 24 are slidably connected to the interior of the annular plate 4, and the ends of two fitting rods 24 fit into a single push arc 5, and the two fitting rods 24 are symmetrically arranged relative to the push arc 5. A sealing spring 25 is fixedly connected between the fitting rods 24 and the annular plate 4; when the push arc 5 moves toward the center of the annular plate 4, the push arc 5 drives the fitting rods 24 to slide, thereby ensuring that the surface of the annular plate 4 on this side is in a smooth state, thereby preventing the two-phase mixture from entering the interior of the annular plate 4;

[0041] In a further embodiment, a guide ring 26 is fixedly connected to the surface of the annular plate 4, and the bottom edge of the guide ring 26 is in contact with the top edge of the fitting rod 24. A guide groove 27 is opened on the surface of the annular plate 4, and the edge of the guide groove 27 is in contact with the bottom edge of the fitting rod 24.

[0042] In some specific embodiments, a plurality of connecting shafts are fixedly connected to the surface of the connecting rod 3, and a connecting groove is opened on the surface of the annular plate 4, and the connecting shafts are adapted to the connecting grooves;

[0043] Working principle of the present invention:

[0044] When installing the annular plate 4, first slide the annular plate 4 corresponding to the connecting shaft and the connecting groove into the inside of the connecting rod 3. After the annular plate 4 slides to the appropriate position, rotate the limit shaft 11 to cause the limit shaft 11 to disengage from the unilateral limit groove 10, pull the limit shaft 11, rotate the limit ring 7, and the limit ring 7 rotates to change the position of the arc groove, causing the limit rod 8 to slide. After the limit rod 8 slides out, turn the limit shaft 11 into the inside of the limit groove 10. The limit rod 8 restricts the annular plate 4 from continuing to slide. At this time, the driving rod 6 fits with the pushing arc 5 and slides into another annular plate 4 in an interlaced manner. Repeat the above steps to complete the installation of the annular plate 4 and the connecting rod 3; then insert the connecting rod 3 into the tower body 1 and fix the position of the tower body 1 and the sealing plate 2;

[0045] When the position of the push arc 5 needs to be adjusted, the corresponding brush 18 is energized. The energization of the brush 18 causes the commutator 17 to rotate, driving the drive column 16 to rotate, pushing the drive rod 6 to slide, causing the push arc 5 to slide. During the sliding process of the push arc 5, the fitting block is driven to move. After the push arc 5 slides to the appropriate position, the power can be turned off.

[0046] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
