Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a horizontal spiral sedimentation centrifuge. Background Technology

[0002] A horizontal spiral sedimentation centrifuge is a general-purpose device that uses the principle of centrifugal sedimentation to continuously separate suspensions. It is widely used in environmental protection, chemical, food, and pharmaceutical industries. Its core working components are a rotating drum and a spiral conveyor that rotate at high speed in the same direction but with a speed difference. Centrifugal force is used to separate the solid and liquid phases. The separated solid phase is pushed by the spiral conveyor to the solid phase outlet of the drum's conical section and is continuously thrown into the receiving cavity between the drum and the outer shell, where it is then discharged through the outlet.

[0003] However, during the operation of current horizontal spiral sedimentation centrifuges, some solid phases, due to their inherent viscosity or electrostatic adsorption properties caused by friction, easily adhere to and accumulate in the containment cavity. Over time, this causes the volume of the containment cavity to gradually decrease until it is completely filled. This not only directly interrupts the normal solid-liquid separation process, but also causes the load on the entire horizontal spiral sedimentation centrifuge to increase sharply, thereby triggering the centrifuge's overload protection system alarm or even shutdown. This seriously affects the continuity and stability of production and reduces the equipment's working efficiency and processing capacity.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0030] This utility model relates to a horizontal spiral sedimentation centrifuge. As the solid phase continuously accumulates in the containment cavity, the dispersing unit rotates within the containment cavity under the action of the rotating shaft. This actively and continuously disperses the solid phase accumulated in the containment cavity, which not only solves the problem of reduced centrifuge separation efficiency caused by solid phase accumulation, but also improves the fluidity of the solid phase to ensure that the solid phase can be smoothly discharged from the containment cavity, thereby further improving the continuity and stability of the centrifuge during the separation process.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] Please see Figures 1 to 5This embodiment proposes a horizontal spiral sedimentation centrifuge, which includes a shell 1 and a rotating drum 2 rotatably disposed inside the shell 1. The two can form a receiving cavity 10 for containing solid phase. After the solid phase enters the receiving cavity 10, it can gradually adhere to and accumulate in the receiving cavity 10 due to its own viscosity or electrostatic adsorption characteristics due to friction. As the solid phase accumulates, the volume of the receiving cavity 10 can gradually decrease until it is completely filled. This not only directly interrupts the normal solid-liquid separation process, but also causes the load of the entire horizontal spiral sedimentation centrifuge to increase sharply, thereby triggering the overload protection system alarm or even shutdown of the centrifuge, which seriously affects the continuity and stability of production and reduces the working efficiency and processing capacity of the equipment.

[0049] Based on the above, the horizontal spiral sedimentation centrifuge proposed in this embodiment further includes a rotating shaft 3 and a dispersing part 4. The rotating shaft 3 can rotate around its axis and is coaxially sleeved between the outer shell 1 and the drum 2, with one end of the rotating shaft 3 extending into the interior of the receiving cavity 10. The dispersing part 4 is located inside the receiving cavity 10 and fixed to the rotating shaft 3, so as to disperse the solid phase accumulated in the receiving cavity 10 during the rotation of the rotating shaft 3. It can be understood that as the solid phase continuously accumulates in the receiving cavity 10, the dispersing part 4 can rotate in the receiving cavity 10 under the action of the rotating shaft 3, and can actively and continuously disperse the solid phase accumulated in the receiving cavity 10. This not only solves the problem of reduced centrifuge separation efficiency caused by solid phase accumulation, but also improves the fluidity of the solid phase to ensure that the solid phase can be smoothly discharged from the receiving cavity 10, thereby further improving the continuity and stability of the centrifuge in the separation process.

[0050] Furthermore, the dispersing section 4 and the outlet 11 of the receiving cavity 10 are arranged vertically opposite each other. It is understood that after the solid phase is dispersed by the dispersing section 4, it can fall directly to the outlet 11 under its own gravity, thus completing the discharge of the solid phase. The cooperation between the screw conveyor and the dispersing section 4 ensures the continuity of the solid phase discharge process.

[0051] In this embodiment, the dispersing section 4 includes a connector 41 and dispersing blades 42. The connector 41 is arranged radially along the drum 2, and one end of the connector 41 is connected to the rotating shaft 3. The dispersing blades 42 are arranged axially along the drum 2 and fixed to the other end of the connector 41. It can be understood that the connector 41 rotates synchronously with the rotating shaft 3, thereby driving the dispersing blades 42 to rotate around the axis of the drum 2, so that the dispersing blades 42 act as scrapers to abut against the solid phase, thereby improving the dispersing efficiency of the solid phase.

[0052] Preferably, there is a gap between the dispersing blade 42 and the inner wall of the outer casing 1. This arrangement can prevent the dispersing blade 42 from colliding with the outer casing 1 during rotation, thereby ensuring the stability of the dispersing blade 42 during rotation.

[0053] Furthermore, the length of the dispersing blade 42 is preferably less than the width of the outlet 11, and the dispersing blade 42 can be extended into the interior of the outlet 11 under the action of the connector 41. That is, the length of the connector 41 can ensure that the dispersing blade 42 can be located inside the outlet 11. With this setting, it can be ensured that the dispersing blade 42 is as close as possible to the inner wall of the outer casing 1, without increasing the maximum outline size of the outer casing 1.

[0054] Furthermore, a connector 41 and a dispersing blade 42 constitute a dispersing assembly. Multiple dispersing assemblies are provided and are evenly distributed around the circumference of the rotating shaft 3. It can be understood that as the rotating shaft 3 rotates continuously, the dispersing blades 42 in each dispersing assembly can come into contact with the solid phase one by one, thereby further ensuring the continuity of solid phase discharge.

[0055] The number of dispersing components can be two, three, or four, but two are preferred.

[0056] In this embodiment, the rotating shaft 3 is provided with an annular mounting groove; and each connecting member 41 includes a connecting rod 411 connected to the dispersing blade 42 and an arc-shaped seat 412 disposed at the end of the connecting rod 411 away from the dispersing blade 42. The arc of the arc-shaped seat 412 is consistent with the arc of the mounting groove. Both ends of the arc-shaped seat 412 are provided with flanges 413. When installing the dispersing part 4, the flanges 413 of different arc-shaped seats 412 can fit against the flanges 413 of another adjacent arc-shaped seat 412, so that the arc-shaped seats 412 of all connecting members 41 can be assembled to form a mounting seat that conforms to the mounting groove. Adjacent connecting members 41 are connected by bolts, that is, the two flanges 413 that fit against each other are connected by bolts. During the tightening of the bolts, the rotating shaft 3 can be clamped between each arc-shaped seat 412, so that the dispersing part 4 can be fixed to the rotating shaft 3. This arrangement facilitates the disassembly and installation of the dispersing part 4.

[0057] The greater the mass of the end of the dispersing blade 42 furthest from the connector 41, the greater its moment of inertia. Therefore, the thickness of the dispersing blade 42 gradually decreases along its extension direction. This design allows for thinning of the end of the dispersing blade 42 furthest from the connector 41, effectively reducing the moment of inertia of the entire dispersing section 4. This, in turn, reduces the torque and power required to drive its rotation (especially during startup and speed changes), achieving energy savings. Furthermore, the thinner end of the dispersing blade 42 experiences less resistance when cutting into the accumulated solid phase, further reducing energy consumption and aiding in the dispersing of the accumulated solid phase.

[0058] In this embodiment, the horizontal spiral sedimentation centrifuge further includes a first sealing part 5 disposed between the outer shell 1 and the rotating shaft 3, and a second sealing part 6 disposed between the rotating shaft 3 and the drum 2, so that the receiving cavity 10 is in a sealed state. This arrangement prevents the solid phase from leaking out through the gaps between the rotating shaft 3 and the outer shell 1, and between the rotating shaft 3 and the drum 2. Furthermore, for explosion-proof horizontal spiral sedimentation centrifuges, it also prevents the leakage of inert gases such as nitrogen inside the receiving cavity 10, thereby ensuring safety performance.

[0059] The first sealing part 5 includes a first mounting base 51, a static seal 52, a limiting member 53, and a first dynamic seal 54. The first mounting base 51 is sleeved between the rotating shaft 3 and the outer shell 1 and is fixedly installed on the frame 7 of the outer shell 1. The limiting member 53 is disposed on the first mounting base 51 and is used to restrict the rotating shaft 3 from moving along its axial direction. The static seal 52 is sealed between the first mounting base 51 and the outer shell 1. The first dynamic seal 54 is sealed between the first mounting base 51 and the rotating shaft 3. Understandably, the first mounting base 51 is fixed on the frame 7 and can be set as a fixed structure between the rotating shaft 3 and the outer shell 1. Under the action of the static seal 52, it can seal the gap between the first mounting base 51 and the outer shell 1. The static seal 52 is preferably an O-ring in the prior art. The first dynamic seal 54 can form a dynamic seal between the first mounting base 51 and the rotating shaft 3. Under the action of the first dynamic seal 54, it can both ensure the rotation of the rotating shaft 3 and seal the gap between the first mounting base 51 and the rotating shaft 3. The first dynamic seal 54 is preferably a rotary seal in the prior art. During the rotation of the rotating shaft 3, under the action of the limiting member 53, the rotating shaft 3 can be axially limited, thereby preventing the rotating shaft 3 from axially moving during the rotation, so as to ensure the dispersing effect of the dispersing part 4 on the solid phase.

[0060] The limiting member 53 includes a first protrusion 531, a second protrusion 532, a limiting sleeve 533, a cover plate 534, and a limiting bolt 535. The first protrusion 531 is disposed on the first mounting base 51, preferably integrally formed with the first mounting base 51 to ensure the connection strength between the two. The first protrusion 531 has a first receiving groove inside for accommodating the first dynamic seal 54. Correspondingly, the second protrusion 532 is disposed on the rotating shaft 3, preferably integrally formed with the rotating shaft 3. The second protrusion 532 is directly opposite the first protrusion 531, so that the first dynamic seal 54 is pressed between the second protrusion 532 and the first receiving groove. Between the slots, an annular groove is provided on the rotating shaft 3. The annular groove can form a second receiving groove with the first mounting seat 51, which is adapted to the shape of the limiting sleeve 533. That is, after the limiting sleeve 533 is installed into the annular groove, it extends to the outside of the annular groove and abuts against the first mounting seat 51. The limiting sleeve 533 is configured to make the first mounting seat 51 and the rotating shaft 3 coaxial. It can also reduce the number of first dynamic seals 54 used. The limiting sleeve 533 is preferably a wear-resistant sleeve in the prior art, thereby reducing the wear of the limiting sleeve 533 during the rotation of the rotating shaft 3 and improving its service life. The first mounting base 51 has a first notch at the end opposite to the first protrusion 531, and the limiting sleeve 533 has a second notch on the portion extending outside the annular groove. The first and second notches face each other and can be assembled to form a third receiving groove for accommodating the cover plate 534. The opening of the third receiving groove faces the side opposite to the first protrusion 531. The cover plate 534 is conformally fitted to the third receiving groove, and after being installed into the third receiving groove, the cover plate 534 can simultaneously abut against the first mounting base 51 and the rotating shaft 3. At this time, the cover plate 534 can be fixed to the first mounting base 51 by the limiting bolt 535. Under the cooperation of the limiting member 53 and the first mounting base 51, the axial limit of the rotating shaft 3 can be completed to prevent the rotating shaft 3 from axially moving during rotation and to avoid interference with the rotation of the rotating shaft 3.

[0061] The second sealing part 6 includes a second mounting base 61, a second dynamic seal 62, and a third dynamic seal 63. The second mounting base 61 is sleeved between the rotating shaft 3 and the drum 2 and is fixedly mounted on the frame 7 of the outer casing 1. The second dynamic seal 62 is sealed between the second mounting base 61 and the rotating shaft 3. The third dynamic seal 63 is sealed between the second mounting base 61 and the drum 2. It is understood that the second mounting base 61 is fixed to the frame 7 via a bearing seat 64, serving as a fixed structure between the rotating shaft 3 and the drum 2. It can cooperate with the first mounting base 51 to keep the rotating shaft 3 coaxial with the drum 2. The second dynamic seal 62 forms a dynamic seal between the rotating shaft 3 and the second mounting base 61. Under the action of the second dynamic seal 62, the rotation of the rotating shaft 3 is ensured, and the gap between the second mounting base 61 and the rotating shaft 3 is sealed. The third dynamic seal 63 can form a dynamic seal between the drum 2 and the second mounting seat 61. Under the action of the second dynamic seal 62, it can both ensure the rotation of the drum 2 and seal the gap between the second mounting seat 61 and the drum 2. Since the drum 2 often needs to rotate at high speed during centrifugation, while the rotation speed of the dispersing part 4 does not need to be too high, the second dynamic seal 62 is preferably a rotary seal in the prior art, and the third dynamic seal 63 is preferably a carbon ring in the prior art.

[0062] Furthermore, for explosion-proof horizontal spiral sedimentation centrifuges, during the centrifugation process, it is necessary to replenish inert gases such as nitrogen into the interior of the outer shell 1 in a timely manner to maintain a slight positive pressure in the internal chambers of the centrifuge, thereby improving safety performance. Therefore, in this embodiment, the second mounting base 61 is also provided with an air passage 611. One end of the air passage 611 is connected to the receiving cavity 10, and the other end is connected to an external air source to continuously supply air to the receiving cavity 10.

[0063] In this embodiment, the horizontal spiral sedimentation centrifuge includes a drive unit 8, which is connected to the rotating shaft 3 and configured to drive the rotating shaft 3 to rotate. It can be understood that under the action of the drive unit 8, the rotating shaft 3 rotates around its own axis, thereby driving the dispersing unit 4 to rotate. During rotation, the dispersing unit 4 can actively and continuously disperse the solid phase accumulated in the receiving cavity 10, thus solving the problem of decreased centrifuge separation efficiency caused by solid phase accumulation.

[0064] Specifically, the drive unit 8 includes a drive member 81, a drive wheel 82, and a driven wheel 83. The drive member 81 is configured to drive the drive wheel 82 to rotate around its own axis. The drive wheel 82 and the driven wheel 83 are connected in a transmission connection. The driven wheel 83 is coaxially connected to the rotating shaft 3 so that the driven wheel 83 rotates synchronously with the rotating shaft 3. It can be understood that the drive wheel 82 is located at the rotating end of the drive member 81, and the driven wheel 83 is fixed on the rotating shaft 3. Under the action of the drive member 81 and the drive wheel 82, the driven wheel 83 can be driven to rotate synchronously with the rotating shaft 3. Preferably, the drive wheel 82 and the driven wheel 83 are sprockets, and they are transmitted through a chain 84. Of course, in some other feasible embodiments, the drive wheel 82 and the driven wheel 83 can be gears, which mesh with each other.

[0065] Furthermore, the drive component 81 includes a third mounting base 811, a rotary motor 812, and a worm gear reducer 813. The worm gear reducer 813 is positioned between the rotary motor 812 and the drive wheel 82 to drive the drive wheel 82 to rotate around its own axis. Furthermore, with the power of the rotary motor 812 remaining constant, the worm gear reducer 813 can convert high-speed power into low-speed, high-torque output to ensure the dispersing effect of the dispersing section 4 on the accumulated solid phase. The rotational speed of the dispersing section 4 is preferably 10-20 rpm.

[0066] Furthermore, the third mounting base 811 includes a platform 8111 for supporting the motor, multiple nuts 8113, and multiple screws 8112. The multiple screws 8112 are mounted on the frame 7, and the platform 8111 can slide along the length of the screws 8112. Each screw 8112 is provided with at least two nuts 8113, which are distributed on the upper and lower sides of the platform 8111 to fix the platform 8111. Under the action of the screws 8112 and nuts 8113, the height of the rotating motor 812 can be adjusted, thereby tensioning the chain 84 to ensure that the dispersing part 4 can rotate stably.

[0067] In some other feasible embodiments, the outer peripheral wall of the rotating shaft 3 forms the bottom wall of the annular groove, the second protrusion 532 forms the side wall of one side of the annular groove, and the driven wheel 83 forms the side wall of the other side of the annular groove. This arrangement can improve the compactness between the rotating shaft 3 and the limiting member 53.

[0068] In addition, the driven wheel 83 is locked to the rotating shaft 3 by a locking bolt 86. The length direction of the locking bolt 86 is parallel to the axial direction of the rotating shaft 3. A washer 85 is also provided between the driven wheel 83 and the rotating shaft 3. The washer 85 helps to evenly distribute the preload of the locking bolt 86, making the driven wheel 83 more stable during operation and reducing the possibility of loosening.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
