Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a centrifugal filtration device for p-toluenesulfonyl chloride. Background Technology

[0002] p-Toluenesulfonyl chloride is an important organic synthesis intermediate, widely used in pharmaceuticals, pesticides, dyes, and polymer materials.

[0003] For example, CN217549121U discloses a centrifugal filtration device for p-toluenesulfonyl chloride, including a treatment tank, a motor, and a stirring rod. The treatment tank includes a tank body, a first outlet, an inlet, and a second outlet. The motor is fixedly installed on the tank body, and the stirring rod is rotatably installed in the tank body and rotates coaxially with the output shaft of the motor. It also includes a filtration mechanism, which is movably installed in the tank body. The filtration mechanism is used to filter out toluenesulfonyl chloride from the water. This invention achieves the effect of centrifugal filtration of the mixed solution by causing the toluenesulfonyl chloride to sink to the filter plate through centrifugal rotation in the tank. By pressing the sliding rod, the movable plate is lowered into the annular groove, at which point the spring is compressed, and the filter plate is then removed from the through-hole, achieving the effect of conveniently removing the filtered toluenesulfonyl chloride.

[0004] However, in the existing technology, due to the high viscosity of toluenesulfonyl chloride solution, or the possible presence of tiny crystals in the solution, the filter cake is prone to clogging. Clogging can cause load fluctuations during centrifugal filtration, affecting the separation effect and thus limiting the practicality of the device to a certain extent. Utility Model Content

A second drive wheel 22 is fixedly installed, and a first helical gear 24 is fixedly installed at the top of one set of second drive wheels 22.

The second ring rack 20 is meshed and connected with multiple sets of second drive wheels 22 respectively. The output end of the second motor 25 drives the second helical gear 26 to rotate. The second helical gear 26 drives one set of second drive wheels 22 to rotate through the first helical gear 24. One set of second drive wheels 22 drives multiple sets of second drive wheels 22, rotating rod 21 and rubber rod 23 to rotate through the second ring rack 20. The rubber rod 23 knocks and vibrates the outer wall of the centrifuge tube 7, shaking off the crystals on the inner wall of the centrifuge tube 7, reducing the blockage of the centrifuge tube 7 and enhancing the filtration efficiency of the device.

[0024] like Figure 1-4As shown, a mounting cavity 8 is provided on the lower surface of the centrifuge cylinder 7, and the bottom end of the centrifuge cylinder 7 is slidably connected to the second rotating groove 10. A first annular rack 9 is fixedly provided on the inner wall of the mounting cavity 8. A first motor 11 is fixedly provided on one side of the lower surface of the main body 1. A first drive wheel 12 is driven by the output end of the first motor 11, and the first drive wheel 12 is meshed and driven by the first annular rack 9. A discharge pipe 17 is fixedly provided at the lower position of the outer surface of the main body 1. A solenoid valve 18 is provided on the surface of the discharge pipe 17. The mounting cavity 8 on the lower surface of the centrifuge cylinder 7 is slidably engaged with the second rotating groove 10, making the device operate more smoothly.

At the same time, the solenoid valve 18 is provided on the discharge pipe 17, which can realize automatic control of material discharge, which not only improves the efficiency of separation and discharge, but also enhances the sealing and operation convenience of the device.

[0025] like Figure 1-4 As shown, the backwash component includes a connecting pipe 14 fixedly installed on the inner wall of the main body 1. A nozzle 15 is fixedly installed at the inner end of the connecting pipe 14. Several nozzles 16 are fixedly installed at equal intervals on the outer surface of the nozzle 15. The outer end of the connecting pipe 14 extends through to the outside of the main body 1. A reserved hole is opened at the top of the main body 1. An end cap 3 is threaded inside the reserved hole. Several anti-slip grips 4 are fixedly installed in a ring on the upper surface of the end cap 3. A feed pipe 5 is fixedly installed on one side of the upper surface of the end cap 3. A one-way valve is installed inside the feed pipe 5. The output end of the external air pump is connected to the connecting pipe 14. While the centrifuge 7 is centrifuging and filtering, the air pump sprays high-pressure air through the connecting pipe 14, the nozzle 15 and the nozzles 16 to the outer surface of the centrifuge 7 to blow off the crystals attached to the inner wall of the centrifuge 7, further reducing the blockage of the centrifuge 7 and further enhancing the filtration efficiency of the device.

[0026] Working principle: In use, firstly, place the centrifuge cylinder 7 in the inner cavity of the main body 1, so that the centrifuge cylinder 7 is slidably connected to the first rotating groove 6, and the bottom end of the centrifuge cylinder 7 is slidably installed in the second rotating groove 10, and the first annular rack 9 is engaged with the first drive wheel 12. Then, hold the anti-slip grip 4 and thread the end cap 3 onto the upper surface of the main body 1, and add toluenesulfonyl chloride into the centrifuge cylinder 7 inside the main body 1 through the feed pipe 5. Then, start the first motor 11. The output end of the first motor 11 drives the first drive wheel 12 to rotate. The first drive wheel 12 drives the centrifuge cylinder 7 to rotate along the second rotating groove 10 and the first rotating groove 6 respectively through the first annular rack 9. The centrifugal force generated by this will filter and separate the toluenesulfonyl chloride. The separated solution will enter the receiving cavity 13 and be discharged to the outside through the discharge pipe 17 by opening the solenoid valve 18. When a large number of crystals adhere and clog the inner wall of the centrifuge cylinder 7, connect the output end of the external air pump to the connecting pipe 14. High-pressure airflow is discharged through connecting pipe 14, nozzle 15, and nozzle 16. Nozzle 16 blows the high-pressure airflow toward the outer surface of centrifuge cylinder 7, blowing away the crystals attached to the surface of centrifuge cylinder 7. When crystals stubbornly clog the surface, the first motor 11 stops driving the centrifuge cylinder 7 to stand still. At this time, the output end of the second motor 25 drives the second helical gear 26 to rotate. The second helical gear 26 drives one set of second drive wheels 22 to rotate through the first helical gear 24. One set of second drive wheels 22 drives multiple sets of second drive wheels 22, rotating rod 21, and rubber rod 23 to rotate through the second ring rack 20. The rubber rod 23 knocks and vibrates the outer wall of centrifuge cylinder 7, shaking off the crystals on the inner wall of centrifuge cylinder 7, further reducing the clogging of centrifuge cylinder 7, and allowing the crystals to accumulate and be stored at the bottom of the centrifuge cylinder 7. Finally, the end cap 3 is removed to take out the centrifuge cylinder 7 for collection. The overall operation is convenient and easy to use, avoids device clogging, improves separation efficiency, and is suitable for large-scale application and promotion.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
