An appropriate amount of activated carbon adsorbent is added to the crude ester, and the activated carbon is used for decolorization and refining to make it meet national standards and internal control indicators.

[0003] After consulting the literature, it is learned that the existing patent (publication number: CN219051703U) discloses a cyclone separator for plasticizer production, including a straight cylinder, the lower end of the straight cylinder is connected to a conical cylinder, the straight cylinder and the conical cylinder are integrally formed, one side of the straight cylinder is connected to a feed pipe, the side wall of the straight cylinder is connected to a clear liquid discharge pipe, the bottom of the conical cylinder is connected to a turbid liquid discharge pipe, the upper end of the straight cylinder is cooperatively connected to a connecting cylinder, a control panel is fixedly installed on the outer wall of the straight cylinder, a self-cleaning mechanism is provided in the connecting cylinder, the clear liquid discharge pipe is provided at the upper end of the feed pipe, and the feed pipe and the straight cylinder are tangentially connected.

[0004] Although the above-mentioned existing device can quickly clean the inner walls of the straight cylinder and the conical cylinder through its own cleaning mechanism, in actual use, since its forward and reverse motors and drive motors are both located inside the device, and the motors need to be routed inside the device, and the drive motors need to move in the vertical direction, the lines will move synchronously, which may cause accumulation of lines. At the same time, because there is liquid inside the equipment, the inside of the device will be relatively humid, and the humid environment will also affect its forward and reverse motors, drive motors and the installed lines, resulting in a shortened service life, affecting the normal use of the device, low practicality and low safety. In view of this, we propose a cyclone separator for plasticizer production to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a hydrocyclone separator for plasticizer production, comprising a straight cylinder 1, a clear liquid discharge pipe and a feed pipe are provided on the side of the straight cylinder 1, a connecting cylinder 2 is fixedly connected to the upper side of the straight cylinder 1, an annular groove 3 is provided on the outer surface of the connecting cylinder 2, a rotating ring 4 is slidably connected to the inner surface of the annular groove 3, a first tooth 5 is fixedly connected to the inner wall of the rotating ring 4, a lifting plate 6 is provided inside the straight cylinder 1, and a docking tooth 7 is provided on the outer surface of the lifting plate 6, the upper and lower sides of the docking tooth 7 are both set as inclined surfaces, and the left and right sides of the docking tooth 7 are set as flat surfaces, and the upper surface of the connecting cylinder 2 is fixedly connected to the first electric tooth 5. The first motor 8 is a motor without a self-locking function. It is a prior art and will not be described in detail below. The output shaft of the first motor 8 rotates and penetrates the interior of the connecting tube 2. The output shaft of the first motor 8 is fixedly connected with a threaded rod 9. The lifting plate 6 is threadedly sleeved on the outer surface of the threaded rod 9. The inner wall of the connecting tube 2 is provided with a limiting groove 10. The limiting groove 10 is connected to the annular through groove 3, and the docking teeth 7 are adapted to the limiting groove 10. The outer surface of the connecting tube 2 is provided with a driving component, and the lower surface of the lifting plate 6 is provided with a cleaning component. When the staff needs to perform cleaning work, they first start the first motor 8, through The rotation of the output shaft of the first motor 8 drives the rotation of the threaded rod 9. Since the docking teeth 7 are slidably connected to the inside of the limiting groove 10, and the lifting plate 6 is threadedly sleeved on the outer surface of the threaded rod 9, the rotation of the threaded rod 9 will drive the lifting plate 6 to descend, thereby causing the docking teeth 7 to descend inside the limiting groove 10. After the docking teeth 7 enter the inside of the annular groove 3, the docking teeth 7 will engage with the first teeth 5. The subsequent start-up drive assembly drives the rotating ring 4 to rotate inside the annular groove 3, thereby driving the rotation of the lifting plate 6, and finally realizing the cleaning of the inner wall of the device by the cleaning assembly. Because the lifting plate 6 and the threaded rod 9 Threaded connection, so the lifting plate 6 and the threaded rod 9 have a certain self-locking property, and the first motor 8 does not have self-locking property, so its output shaft can rotate freely, thereby driving the threaded rod 9 to rotate synchronously, and finally the lifting plate 6 will not move up and down when it rotates. The above structure avoids the problem of circuits inside the device as much as possible, and makes the drive assembly and the first motor 8 located outside the device, extending the service life of the device as much as possible, and also making it convenient for staff to inspect and repair it. It has high practicality and high safety, and solves the problem of inconvenience in using some existing cyclone separators for plasticizer production.

[0028] Furthermore, a sliding groove 11 extending outward is opened inside the lifting plate 6 , the docking teeth 7 are slidably connected inside the sliding groove 11 , and a spring 12 is fixedly connected between the docking teeth 7 and the inner wall of the sliding groove 11 .

[0029] Furthermore, the driving assembly includes a driving box 13, which is hollow inside. The driving box 13 is fixedly connected to the outer surface of the connecting tube 2. The driving box 13 is rotatably connected to a rotating shaft 14. The outer surface of the rotating shaft 14 is sleeved with a gear 15. The outer surface of the rotating ring 4 is fixedly connected with a second tooth 17. The second tooth 17 is meshed with the gear 15. The upper surface of the driving box 13 is fixedly connected to a second motor 16. The second motor 16 is a motor with a self-locking function. It is also a prior art and will not be described below. The output shaft of the second motor 16 rotates and passes through the interior of the driving box 13 and is fixedly connected to the rotating shaft 14. By starting the second motor 16, the rotation of the rotating shaft 14 is driven. The rotation of the rotating shaft 14 drives the rotation of the gear 15, thereby driving the rotating ring 4 to rotate in the annular groove 3. The arrangement of the driving box 13 avoids the upper part of the connecting tube 2 from rotating, and finally realizes the rotation of the lifting plate 6. When the staff needs to retract the cleaning assembly, they first turn off the second motor 16. At this time, the self-locking property of the second motor 16 is relied on to avoid the rotating ring 4 When the self-rotation occurs, the first motor 8 is subsequently started to reverse the threaded rod 9. Since the docking teeth 7 and the first teeth 5 are engaged, and the rotating ring 4 does not rotate, the lifting plate 6 will not be driven to rotate when the threaded rod 9 rotates, and then the threaded rod 9 will drive the lifting plate 6 to rise. When the inclined surface of the docking teeth 7 contacts the inner wall of the connecting tube 2, the docking teeth 7 will slide into the inside of the sliding groove 11, and the spring 12 will contract. After the docking teeth 7 and the first teeth 5 are completely disengaged, the docking teeth 7 will be completely retracted into the inside of the sliding groove 11. At this time, When the first teeth 5 are no longer engaged with the docking teeth 7, the rotation of the threaded rod 9 will drive the rotation of the lifting plate 6. When the docking teeth 7 are subsequently rotated to the outside of the limit groove 10, the elastic force of the spring 12 itself will cause the docking teeth 7 to be stuck in the inside of the limit groove 10. Therefore, the limit groove 10 will restrict the lifting plate 6, and the lifting plate 6 can be subsequently lifted. The setting of the driving component is improved, the smoothness of the operation of the device is improved, the rising or falling of the cleaning component is facilitated, and the practicality of the device is further improved.

[0030] Furthermore, the lower portion of the straight cylinder 1 is fixedly connected to a conical cylinder 20 , and the lower portion of the conical cylinder 20 is fixedly connected to a turbid liquid discharge pipe 21 .

[0031] Furthermore, the cleaning assembly includes a fixed rod 18, which is fixedly connected to the lower surface of the lifting plate 6. The fixed rod 18 is located at the eccentric point of the lower surface of the lifting plate 6. The outside of the fixed rod 18 is fixedly connected to a cleaning rod 19 through a cross bar. The cleaning rod 19 includes two vertical rods and one oblique rod. The two vertical rods in the cleaning rod 19 are respectively adapted to the straight cylinder 1 and the turbid liquid discharge pipe 21, and the oblique rod in the cleaning rod 19 is adapted to the conical cylinder 20. The rotation of the lifting plate 6 can drive the fixed rod 18 to perform circular motion, thereby driving the cleaning rod 19 to clean the inner wall of the device.

[0032] Working principle:

[0033] When the cyclone separator for plasticizer production is in use, the material is introduced into the feed pipe through an external pressure pump, and a vortex rotating around the inner wall of the straight cylinder 1 is formed. The liquid rotates to generate centrifugal force, and the activated carbon particles in the liquid are thrown to the wall of the device under the action of the centrifugal force, and flow down along the wall in a spiral line to the turbid liquid discharge pipe 21, and the clarified liquid rises and is discharged through the clear liquid discharge pipe, thereby completing the separation. After the separation operation is completed, the first motor 8 is started, and the rotation of the output shaft of the first motor 8 drives the rotation of the threaded rod 9. Because the docking teeth 7 are slidably connected to the inside of the limit groove 10, and the lifting plate 6 is threadedly sleeved on the outer surface of the threaded rod 9, the screw The rotation of the threaded rod 9 will drive the lifting plate 6 to descend, thereby causing the docking teeth 7 to descend inside the limit groove 10. After the docking teeth 7 enter the inside of the annular groove 3, the docking teeth 7 will engage with the first teeth 5. The subsequent start-up drive assembly will drive the rotating ring 4 to rotate inside the annular groove 3, thereby driving the rotation of the lifting plate 6, and finally realizing the cleaning assembly of the device inner wall. Because the lifting plate 6 and the threaded rod 9 are threadedly connected, the lifting plate 6 and the threaded rod 9 have a certain self-locking property, and the first motor 8 does not have self-locking property, so its output shaft can rotate freely, thereby driving the threaded rod 9 to rotate synchronously, and finally making the lifting plate 6 not move up and down when rotating.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
