Description

Technical Field

[0001] This invention relates to the field of centrifuge technology, and in particular to a high-efficiency horizontal screw sedimentation centrifuge for liquid-material separation. Background Technology

[0002] Horizontal spiral sedimentation centrifuges utilize a spiral conveyor system, which effectively separates settled solids from the liquid during centrifugation. The spiral structure improves the discharge efficiency of solid particles and reduces backflow during sedimentation, thereby achieving continuous operation and efficient separation.

[0003] In actual use, the high-speed rotation of the drum and the penetration of the internal slurry often cause great damage to the sealing parts. As a result, the sealing parts have become one of the consumables. Traditional horizontal screw sedimentation centrifuges are very cumbersome to maintain, requiring the disassembly of many parts to replace and maintain the relevant sealing parts, which is time-consuming and laborious. In view of this drawback of the inconvenience of replacing sealing parts, we propose a new type of high-efficiency liquid separation horizontal screw sedimentation centrifuge. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings in the prior art, the present invention provides a high-efficiency horizontal screw sedimentation centrifuge for liquid separation that facilitates the replacement of sealing parts: This invention provides a high-efficiency horizontal screw sedimentation centrifuge for liquid separation, comprising a base. A main collection trough with a downwardly recessed, semi-cylindrical structure is pre-reserved in the center of the top of the base. An arc-shaped outer cover with an opening facing downwards and symmetrical to the shape of the main collection trough is fixed to the top of the base. The inner cavity of the arc-shaped outer cover and the inner cavity of the main collection trough form a distribution chamber. An outer drum is rotatably connected to the distribution chamber, and two ends of the outer drum are respectively pre-reserved with coaxial and equal-diameter outer shaft tubes. An inner drum is rotatably connected inside the outer drum. The outer circumference of the inner drum is provided with spiral ribs. Two inner shaft tubes are respectively pre-reserved at both ends of the inner drum and are coaxially and rotatably connected to the corresponding outer shaft tubes. Sealed bearing assemblies are provided between the outer wall of the second shaft tube and the inner circumferential wall of the first outer shaft tube. Two symmetrical sealing rings are slidably engaged between the inner circumferential wall of the arc-shaped outer cover and the main collection trough and the outer circumferential wall of the first outer drum. A spiral sealing ring is engaged on the inner circumferential wall of the sealing rings. The two sealing rings divide the material distribution chamber into a solid discharge chamber, an intermediate chamber and a liquid discharge chamber. Solid discharge outlets and liquid discharge outlets are respectively opened near the two ends of the outer circumferential wall of the first outer drum. An arc-shaped maintenance cover is provided in the middle of the intermediate chamber of the arc-shaped outer cover. A T-shaped feed pipe is inserted into one of the second inner shaft tubes and extends into the interior of the second inner drum. The two outlets of the feed pipe are embedded in the surface of the second inner drum.

[0005] Preferably, both ends of the main collection trough are provided with bearing slots, and two symmetrical anti-slip bearings, namely anti-slip bearing one and anti-slip bearing two, are respectively engaged in the two bearing slots. Two outer shaft tubes are respectively rotatably connected in the corresponding anti-slip bearing one and anti-slip bearing two. Ordinary sealing rings are provided on the side of anti-slip bearing one and anti-slip bearing two near the material distribution chamber. Solid discharge ports and liquid discharge pipes are respectively provided at the bottom of the main collection trough near both ends to discharge solid particles and liquid generated in the solid discharge chamber and liquid discharge chamber, respectively.

[0006] Preferably, axial limiting plates are fixed to the bottom of the main aggregate trough and the inner circumferential wall of the arc-shaped outer cover near both ends, and the sealing ring retainer is fixed to the surface of the corresponding axial limiting plate by bolts; to ensure that the sealing ring retainer will not be squeezed by the excretory force generated during discharge and thus will not be axially displaced.

[0007] Preferably, the outer shaft tube, located away from the feed pipe, passes through the anti-slip bearing and is fixed with a driven pulley. A low-level platform is provided on the upper surface of the base near the driven pulley. A main motor is fixed on the low-level platform near the front edge, and a drive pulley is fixed at the top of the output shaft of the main motor, which is connected to the driven pulley in a transmission manner. The slippage of the belt can be used to protect the main motor during rotation, preventing overload from burning out the main motor.

[0008] Preferably, an anti-slip groove is provided on the upper surface of the low-level platform below the end of the inner shaft tube 2, and a sliding seat is slidably connected in the anti-slip groove. A reduction motor is fixed on the upper surface of the sliding seat, and a coupling is fixed at the top of the output shaft of the reduction motor. A shaft connecting barrel with an opening facing the inner shaft tube 2 is fixed at one end of the coupling near the inner shaft tube 2. The edge of the barrel opening is fixed to the end of the inner shaft tube 2 by bolts. With the help of the sealed bearing assembly, the inner drum 2 can be driven by the reduction motor to rotate at low speed inside the outer drum 1.

[0009] Preferably, the sliding seat has two parallel and horizontal guide rods fixed at one end near the main collection trough. The guide rods are parallel to the axis of the inner shaft tube two, and the bottom of the anti-slip groove is provided with a sliding insertion hole that matches the diameter of the guide rod. The upper surface of the sliding seat is also provided with positioning bolts. This facilitates the disassembly and assembly of the overall geared motor and ensures that its rotation axis is still on a straight line with the axis of the inner shaft tube two after installation.

[0010] Preferably, the inner circumferential inner wall of the inner shaft tube two near the lower platform is provided with a hexagonal groove one, and a hexagonal inner insert shaft is inserted and fixed at the end of the inner shaft tube two near the hexagonal groove. The inner circumferential inner wall of the shaft connecting barrel is provided with a hexagonal groove two that matches the outer diameter of the other end of the hexagonal inner insert shaft. By providing a hexagonal inner insert shaft that is slidably inserted between the inner shaft tube two and the shaft connecting barrel, the torque can be improved.

[0011] Preferably, the inner circumferential wall of the sealing ring retainer is provided with an annular groove, and the adjacent turns of the spiral sealing ring are tightly fitted after being wound, ensuring that the spiral sealing ring forms a whole and will not produce spiral leakage from its gaps.

[0012] Preferably, the sealed bearing assembly includes a T-shaped blocking ring fixed to the inner circumference of the outer drum and near the junction of the inner circumference of the outer shaft tube. The inner circumference of the T-shaped blocking ring is rotatably connected to a clamping tube. The outer circumference of the clamping tube is fitted with two rings of balls. A Z-shaped sealing ring is fixed to one end of the clamping tube near the feed tube. Three clamping springs are fixed to the other end of the clamping tube in a centrally symmetrical distribution. The ends of the three clamping springs are fixed to the same internally threaded clamping tube.

[0013] Preferably, one end of the Z-shaped sealing ring is snapped and fixed to the end of the clamping tube, and the other end of the Z-shaped sealing ring slides against the protruding annular edge surface of the T-shaped blocking ring. The Z-shaped sealing ring itself has a certain folding back thrust, which can improve the overall pre-tightening sealing ability and wear resistance.

[0014] The beneficial effects of this invention are as follows: 1. By setting a sliding connection sealing ring retainer and a replaceable spiral sealing ring that can be pulled out completely, when the spiral sealing ring needs to be replaced, simply open the arc-shaped inspection cover and pull out the worn spiral sealing ring for replacement. Replacement is convenient and does not require disassembling more parts.

[0015] 2. By setting up a tightly wound spiral sealing ring, combined with the constraint of the annular groove, the spiral sealing ring is ensured to form a whole, and no spiral leakage will occur from its gaps.

[0016] 3. By setting up a clamping tube and an internally threaded clamping tube that can be disassembled as a whole, and in conjunction with a detachable shaft connector, when the Z-shaped seal ring needs to be replaced, simply disassemble the internally threaded clamping tube and the clamping tube outwards to remove the Z-shaped seal ring, and then replace or clean it.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In this embodiment, refer to Figures 1-7A high-efficiency horizontal screw sedimentation centrifuge for liquid separation includes a base 1 with an overall rectangular box-shaped structure and an opening facing downwards. A main collection trough 101 with a downwardly recessed semi-cylindrical structure is pre-reserved in the center of the top of the base 1. An arc-shaped outer cover 3 with an opening facing downwards and symmetrical in shape to the main collection trough 101 is fixed to the top of the base 1. The inner cavity of the arc-shaped outer cover 3 and the inner cavity of the main collection trough 101 form a distribution chamber. A cylindrical structure with an internal cavity is rotatably connected within the distribution chamber. An outer drum 6 has coaxial outer shaft tubes of the same diameter pre-installed at both ends. An inner drum 18, with an internal cavity and a cylindrical structure, is rotatably connected inside the outer drum 6. The outer circumferential outer wall of the inner drum 18 is provided with helical ribs. Both ends of the inner drum 18 have coaxial inner shaft tubes 2, rotatably connected to the corresponding outer shaft tubes. Sealed bearing assemblies are provided between the outer wall of the inner shaft tube 2 and the inner circumferential inner wall of the outer shaft tube 1. An arc-shaped outer cover is also provided. Two symmetrical sealing rings 4 are slidably engaged between the inner circumference of the main collection trough 101 and the outer circumference of the outer drum 6, and a spiral sealing ring 401 is engaged on the inner circumference of the sealing rings 4. The two sealing rings 4 divide the material distribution chamber into a solid discharge chamber, an intermediate chamber and a liquid discharge chamber. The outer circumference of the outer drum 6 has a solid discharge outlet 601 and a liquid discharge outlet near both ends. An arc-shaped maintenance cover 5 is provided in the middle of the intermediate chamber of the arc-shaped outer cover 3. A T-shaped feed pipe 2 is inserted into one of the inner shaft tubes 2 and extends into the inner drum 2 18. The two outlets of the feed pipe 2 are embedded in the surface of the inner drum 2 18. By setting the slidingly connected sealing rings 4 and the spiral sealing ring 401 that can be pulled out for replacement, when the spiral sealing ring 401 needs to be replaced, simply open the arc-shaped maintenance cover 5 and pull out the worn spiral sealing ring 401 for replacement. Replacement is convenient and does not require disassembling more parts.

[0021] Reference Figure 4 and Figure 7 Both ends of the main collection trough 101 are provided with bearing slots 104, and anti-slip bearing 19 and anti-slip bearing 20 are respectively engaged in the two bearing slots 104. The two outer shaft tubes are respectively rotatably connected in the corresponding anti-slip bearing 19 and anti-slip bearing 20. Ordinary sealing rings are provided on the side of anti-slip bearing 19 and anti-slip bearing 20 near the material distribution chamber. Solid discharge port 14 and liquid discharge pipe 13 are respectively provided at the bottom of the main collection trough 101 near both ends to discharge solid particles and liquid generated in the solid discharge chamber and liquid discharge chamber respectively.

[0022] Reference Figure 7The bottom of the main collection trough 101 and the inner circumference of the arc-shaped outer cover 3 are both fixed with axial limiting plates 103 near both ends. The sealing ring 4 is fixed to the surface of the corresponding axial limiting plate 103 by bolts. This ensures that the sealing ring 4 will not be squeezed by the excrement during discharge and thus will not be axially displaced.

[0023] Reference Figure 1 and Figure 6 A driven pulley 7 is fixed to the outer shaft tube away from the feed pipe 2 through the anti-slip bearing 20. A low-level platform is provided on the upper surface of the base 1 near the driven pulley 7. A main motor 11 is fixed on the low-level platform near the front edge. The top of the output shaft of the main motor 11 is fixed with a drive pulley 12 that is connected to the driven pulley 7. Through the belt drive, the slippage property of the belt can be used to protect the main motor 11 during rotation, preventing overload and burnout of the main motor 11.

[0024] Reference Figure 1 , Figure 6 and Figure 7 An anti-slip groove 102 is provided on the lower surface of the low-level platform near the end of the inner shaft tube 2. A sliding seat 10 is slidably connected in the anti-slip groove 102. A reduction motor 9 is fixed on the upper surface of the sliding seat 10. A coupling 15 is fixed at the top of the output shaft of the reduction motor 9. A shaft connecting barrel 8 with an opening facing the inner shaft tube 2 is fixed at one end of the coupling 15 near the inner shaft tube 2. The edge of the barrel opening of the shaft connecting barrel 8 is fixed to the end of the inner shaft tube 2 by bolts. With this arrangement and the function of the sealed bearing assembly, the inner drum 2 18 can be driven by the reduction motor 9 to rotate at low speed inside the outer drum 1 6.

[0025] Reference Figure 6 Two parallel and horizontal guide rods are fixed at one end of the sliding seat 10 near the main collection trough 101. The guide rods are parallel to the axis of the inner shaft tube 2. The bottom of the anti-slip groove 102 is provided with a sliding insertion hole that matches the diameter of the guide rod. The upper surface of the sliding seat 10 is also provided with positioning bolts. This facilitates the disassembly and assembly of the overall reduction motor 9 and ensures that its rotation axis is still on a straight line with the axis of the inner shaft tube 2 after installation.

[0026] Reference Figures 4-6 The inner shaft tube 2 has a hexagonal groove 1 on the inner circumference of one end near the lower platform, and a hexagonal inner insert shaft 16 is inserted and fixed at the end of the inner shaft tube 2 near the hexagonal groove. The inner circumference of the shaft connecting barrel 8 has a hexagonal groove 2 that matches the outer diameter of the other end of the hexagonal inner insert shaft 16. By setting the hexagonal inner insert shaft 16 that is slidably inserted between the inner shaft tube 2 and the shaft connecting barrel 8, the torque can be improved.

[0027] Reference Figure 7The inner circumference of the sealing ring retainer 4 is provided with an annular groove, and the adjacent turns of the spiral sealing ring 401 are tightly fitted after being wound, ensuring that the spiral sealing ring 401 forms a whole and will not produce spiral leakage from its gaps.

[0028] Reference Figures 4-6 The sealed bearing assembly includes a T-shaped retaining ring 23 fixed to the inner circumference of the outer drum 6 and near the junction of the inner circumference of the outer shaft tube. The inner circumference of the T-shaped retaining ring 23 is rotatably connected to a clamping tube 17. Two rings of balls are embedded in the outer circumference of the clamping tube 17. A Z-shaped sealing ring 22 is fixed to one end of the clamping tube 17 near the feed tube 2. Three clamping springs are fixed to the other end of the clamping tube 17 in a centrally symmetrical distribution. The ends of the three clamping springs are fixed to the same internally threaded clamping tube 21. With the detachable shaft connecting barrel 8, when the Z-shaped sealing ring 22 needs to be replaced, the internally threaded clamping tube 21 and the clamping tube 17 can be slowly disassembled outward to remove the Z-shaped sealing ring 22, and then it can be replaced or cleaned.

[0029] In this invention, one end of the Z-shaped sealing ring 22 is snapped and fixed to the end of the clamping tube 17, and the other end of the Z-shaped sealing ring 22 slides against the protruding annular edge surface of the T-shaped blocking ring 23. The Z-shaped sealing ring 22 itself has a certain folding back thrust, which can improve the overall pre-tightening sealing ability and wear resistance.

[0030] Working principle: When using this device, the solid-liquid mixture to be separated is injected into the outer circumference of the inner drum 18 through the feed pipe 2. At this time, the liquid will undergo centrifugal separation under the action of the rapidly rotating outer drum 6. The solid is slowly pushed by the spiral ribs to one end near the solid discharge port 601, while the liquid is forced to move in the opposite direction and is finally discharged from the liquid discharge pipe 13 at the other end. The solid will be discharged from the solid discharge port 14. When the Z-shaped sealing ring 22 needs to be replaced, simply disassemble the inner threaded abutment tube 21 and the clamping tube 17 outward to remove the Z-shaped sealing ring 22 for replacement or cleaning. When the spiral sealing ring 401 needs to be replaced, simply open the arc-shaped inspection cover 5 first, then slowly slide the sealing ring retainer 4 out to the middle position near the arc-shaped inspection cover 5, and then pull out the worn spiral sealing ring 401 for replacement.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
