Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically to a centrifugal extractor for tar processing wastewater. Background Technology

[0002] Tar processing wastewater is a complex type of industrial wastewater, primarily originating from processes such as coal coking and coal gasification. Its typical components include organic phase products, aqueous residual phases, and byproducts. Organic phase products include phenolic substances, neutral oils, and nitrogen-containing compounds; aqueous residuals include residual organic matter, inorganic pollutants, and trace solvents. To recover these useful substances, centrifugal extractors are typically used to treat the tar processing wastewater. However, the rotational torque during centrifugation can cause vibration and instability in the centrifugal extractor. Therefore, it is necessary to design a centrifugal extractor for tar processing wastewater that can balance the rotational torque and improve the operational stability of the centrifugal extractor. Summary of the Invention

[0003] The purpose of this invention is to provide a centrifugal extractor for tar processing wastewater, which has the advantages of balancing rotational torque and improving the working stability of the centrifugal extractor.

[0004] The technical solution adopted is as follows:

[0005] A centrifugal extractor for tar processing wastewater includes a frame, an internal mounting ring, a centrifugal extractor body, and multiple mounting seats on the side of the centrifugal extractor body. Each mounting seat is connected to the mounting ring using a shock-absorbing seat. A drive motor is mounted on the upper end of the centrifugal extractor body, and the drive motor has a drive shaft extending into the centrifugal extractor body. A first bevel gear is mounted on the drive shaft. A support is mounted on the upper end of the centrifugal extractor body, and a transmission shaft is horizontally rotatably mounted on the support. A driven shaft is vertically rotatably mounted on the support above the drive motor. A balance disc and a second bevel gear are respectively mounted at the upper and lower ends of the driven shaft. A third bevel gear meshes with both the second and first bevel gears on the transmission shaft.

[0006] Preferably, the shock-absorbing seat includes a base plate and a top plate, and a compression spring is fixedly disposed between the base plate and the top plate.

[0007] Preferably, a limiting steel cable is also provided inside the compression spring between the bottom plate and the top plate.

[0008] Preferably, the first bevel gear and the second bevel gear have the same specifications.

[0009] Preferably, the side of the balance disc is provided with a plurality of threaded holes, and a balance block is detachably installed in the threaded holes.

[0010] Compared to existing technologies, the advantages are:

[0011] This invention achieves the reverse rotation of the first and second bevel gears through the meshing of the first and third bevel gears, and the meshing of the second and third bevel gears. This, in turn, enables the balance disc to rotate in the opposite direction to the drive shaft. The balance disc is used to counteract the torque generated during centrifugal extraction, making the centrifugal extractor work more smoothly. Attached Figure Description

[0016] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0017] Example 1: A centrifugal extractor for tar processing wastewater includes a frame 1, an installation ring 2 inside the frame 1, a centrifugal extractor body 3 inside the installation ring 2, and multiple mounting seats 4 on the side of the centrifugal extractor body 3. The mounting seats 4 are connected to the installation ring 2 by vibration damping seats. The vibration damping seats are used to absorb the vibration of the centrifugal extractor body 3 during operation, thereby reducing the vibration transmitted to the frame 1 and making the frame 1 more stable.

[0018] A drive motor 7 is provided at the upper end of the centrifugal extractor body 3. The drive motor 7 is provided with a drive shaft 8 extending into the centrifugal extractor body 3. The drive motor 7 provides power to the centrifugal extractor through the drive shaft 8. A first bevel gear 9 is provided on the drive shaft 8. A bracket 11 is provided at the upper end of the centrifugal extractor body 3. A transmission shaft 10 is horizontally rotatably mounted on the bracket 11. A bearing seat is provided on the bracket 11. The transmission shaft 10 is installed in the bearing seat.

[0019] A driven shaft 12 is vertically rotatably mounted on the bracket 11 at the upper end of the drive motor 7. A balance disc 14 and a second bevel gear 13 are respectively mounted at the upper and lower ends of the driven shaft 12. A third bevel gear 15 is mounted on the transmission shaft 10, which meshes with both the second bevel gear 13 and the first bevel gear 9. Through the meshing of the first bevel gear 9 and the third bevel gear 15, and the meshing of the second bevel gear 13 and the third bevel gear 15, the first bevel gear 9 and the second bevel gear 13 rotate in opposite directions, thereby realizing that the balance disc 14 rotates in opposite directions with the transmission shaft 10. The balance disc 14 is used to counteract the torque generated during the centrifugal extraction process.

[0020] Example 2: A centrifugal extractor for tar processing wastewater includes a frame 1, an mounting ring 2 inside the frame 1, a centrifugal extractor body 3 inside the mounting ring 2, and multiple mounting seats 4 on the side of the centrifugal extractor body 3. The mounting seats 4 are connected to the mounting ring 2 by shock-absorbing seats. The shock-absorbing seats include a bottom plate and a top plate. A compression spring 5 is fixedly installed between the bottom plate and the top plate. A limiting steel cable 6 is also installed inside the compression spring 5 between the bottom plate and the top plate. The shock-absorbing seats are used to absorb the vibration of the centrifugal extractor body 3 during operation, thereby reducing the vibration transmitted to the frame 1 and making the frame 1 more stable.

[0021] A drive motor 7 is provided at the upper end of the centrifugal extractor body 3. The drive motor 7 is provided with a drive shaft 8 extending into the centrifugal extractor body 3. The drive motor 7 provides power to the centrifugal extractor through the drive shaft 8. A first bevel gear 9 is provided on the drive shaft 8. A bracket 11 is provided at the upper end of the centrifugal extractor body 3. A transmission shaft 10 is horizontally rotatably mounted on the bracket 11. A bearing seat is provided on the bracket 11. The transmission shaft 10 is installed in the bearing seat.

[0022] A driven shaft 12 is vertically rotatably mounted on the bracket 11 at the upper end of the drive motor 7. A balance disc 14 and a second bevel gear 13 are respectively mounted on the upper and lower ends of the driven shaft 12. A third bevel gear 15 is mounted on the transmission shaft 10, which meshes with both the second bevel gear 13 and the first bevel gear 9. The first bevel gear 9 and the second bevel gear 13 have the same specifications, so that the drive shaft 8 and the driven shaft 12 rotate at the same speed but in opposite directions. Multiple threaded holes 16 are evenly arranged on the side of the balance disc 14. A balance block 17 is detachably mounted in the threaded hole 16. By performing dynamic balancing and adding balance blocks 17 at appropriate positions, the balance disc 14 can rotate smoothly.

[0023] The working principle is as follows:

[0024] The start-up drive mechanism drives the centrifugal extractor body 3 to work. During operation, the centrifugal extractor body 3 achieves the opposite rotation of the first bevel gear 9 and the second bevel gear 13 through the meshing of the first bevel gear 9 and the third bevel gear 15, and the meshing of the second bevel gear 13 and the third bevel gear 15. This causes the balance disc 14 to rotate in the opposite direction to the drive shaft 10. The balance disc 14 is used to counteract the torque generated during the centrifugal extraction process, making the centrifugal extractor work more smoothly.

[0025] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
