Description

Technical Field

[0001] This utility model relates to the field of research and development technology of purification processes for pharmaceutical intermediates, and in particular to a purification device that is easy to filter. Background Technology

[0002] Pharmaceutical intermediates are essentially chemical raw materials or products used in drug synthesis processes. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis. The preparation process is as follows:

[0003] 1. Selection and processing of starting materials: The preparation of pharmaceutical intermediates usually begins with specific starting materials. For example, acetylene and formaldehyde can be used to synthesize certain pharmaceutical intermediates.

[0004] 2. Chemical Reactions: Various chemical reactions, such as addition reactions and esterification reactions, will occur during the preparation process. These reactions usually require specific catalysts and reaction conditions.

[0005] 3. Separation and purification: After the reaction is complete, the product needs to be separated and purified to remove impurities and obtain a pure intermediate. This usually involves steps such as distillation and extraction.

[0006] However, this patent has some shortcomings in its application. In the processing of pharmaceutical intermediates, the product needs to be filtered and purified after the reaction is completed. However, existing purification devices generally filter the product using filter cartridges. During filtration, impurities easily remain on the filter cartridges, causing them to become clogged and affecting the filtration effect. Therefore, the filter cartridges need to be removed and cleaned. However, removing the filter cartridges requires shutting down the filtration equipment, increasing operating costs and reducing the efficiency of the filtration and purification device. Utility Model Content

[0007] The purpose of this invention is to provide a purification device that facilitates filtration, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A purification device for easy filtration includes a purification cylinder. The purification cylinder has a first partition plate and a second partition plate inside. A bidirectional motor is fixedly mounted on the top of the first partition plate. Fixed rods are fixedly connected to the output ends of both sides of the bidirectional motor.

[0010] As a preferred embodiment of this utility model, a filter element is provided on the top of the first partition plate, a screwing member is provided on the top of the filter element, and a threaded part is provided on the outer end of the filter element near the screwing member. The threaded part is threadedly connected to the first partition plate.

[0011] As a preferred embodiment of this utility model, a Y-shaped connecting pipe is provided at the bottom of the second partition plate, the top of the Y-shaped connecting pipe penetrates through the second partition plate, the top of the Y-shaped connecting pipe is connected to the liquid outlet of the filter element, and a straight connecting pipe is fixedly connected to the bottom of the Y-shaped connecting pipe.

A liquid outlet pipe is provided on the side of the second valve. One end of the liquid outlet pipe is fixedly connected to the second valve, and the other end of the liquid outlet pipe extends to the outside of the purification cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the backwashing process of the filter element is realized through the combined use of the water injection pipe, water pump, straight connecting pipe, Y-type connecting pipe, and second partition plate. This allows the filter element to be cleaned without disassembly, which is more time-saving and convenient than the traditional method of disassembling the filter element. It can improve the filtration efficiency of the purification device. When the filter element needs to be cleaned, both the second valve and the first valve are closed, the water injection pipe and the water pipe are connected, and then the water pump is started. The water pump delivers water along the straight connecting pipe and the Y-type connecting pipe to the inside of the filter element, backwashing the impurities attached to the surface of the filter element. Then the first valve is opened, allowing the waste liquid to flow out from the waste liquid discharge pipe, achieving a rapid cleaning effect.

At the same time, it eliminates the need for frequent disassembly of the filter element, reducing maintenance costs.

[0019] 2. In this utility model, by setting up a bidirectional motor, a fixed rod, a first conical gear, a second conical gear, a stirring rod, and a mixing paddle, the reactants entering the purification cylinder are mixed and stirred, so that the particles of the reactants are evenly dispersed, thereby achieving rapid filtration and improving filtration efficiency. In addition, the stirring process can also increase the liquid velocity in the purification cylinder, causing impurities adhering to the surface of the filter element to fall off, reducing the resistance of the filter element surface, thereby increasing the filtration speed. In use, the switch of the bidirectional motor is turned on, and the bidirectional motor controls the fixed rod and the first conical gear to rotate. At the same time, the first conical gear drives the stirring rod to rotate through the second conical gear, so that the mixing paddle can fully mix the reactants in the purification cylinder, thereby accelerating the reaction process and improving filtration efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0027] A purification device for easy filtration includes a purification cylinder 1. The purification cylinder 1 has a first partition plate 15 and a second partition plate 16 inside. An inlet pipe 2 and a waste liquid discharge pipe 5 are respectively provided on both sides of the purification cylinder 1. The inlet pipe 2 is located below the first partition plate 15, and the waste liquid discharge pipe 5 is located above the second partition plate 16. A first valve 6 is provided on the side of the waste liquid discharge pipe 5. A top cover 8 is threadedly connected to the top of the purification cylinder 1, and a support leg 7 is fixedly connected to the bottom of the purification cylinder 1.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a Y-shaped connecting pipe 19 is provided at the bottom of the second partition plate 16. The top of the Y-shaped connecting pipe 19 penetrates the second partition plate 16 and is connected to the liquid outlet of the filter element 17. A straight connecting pipe 20 is fixedly connected to the bottom of the Y-shaped connecting pipe 19. A second valve 21 and a third valve 22 are respectively installed on both sides of the straight connecting pipe 20. A liquid outlet pipe 3 is provided on the side of the second valve 21. One end of the liquid outlet pipe 3 is fixedly connected to the second valve 21, and the other end of the liquid outlet pipe 3 extends to the outside of the purification cylinder 1. A water pump 23 is provided on the side of the third valve 22. The water pump 23 is installed on the inner bottom wall of the purification cylinder 1. The side of the third valve 22 is fixedly connected to the water outlet of the water pump 23. A water injection pipe 4 is provided on the side of the water pump 23. One end of the water injection pipe 4 is fixedly connected to the water inlet of the water pump 23, and the other end of the water injection pipe 4 extends to the outside of the purification cylinder 1.

[0029] The backwashing process of filter element 17 is achieved through the coordinated use of water injection pipe 4, water pump 23, straight connecting pipe 20, Y-type connecting pipe 19, and second partition plate 16. This allows filter element 17 to be cleaned without disassembly, which is more time-saving and convenient than the traditional method of disassembling filter elements and can improve the filtration efficiency of the purification device. When filter element 17 needs to be cleaned, both second valve 21 and first valve 6 are closed, water injection pipe 4 is connected to the water pipe, and then water pump 23 is started. Water pump 23 delivers water along straight connecting pipe 20 and Y-type connecting pipe 19 to the inside of filter element 17 to backwash the impurities attached to the surface of filter element 17. Then, first valve 6 is opened, allowing waste liquid to flow out from waste liquid discharge pipe 5, achieving a rapid cleaning effect. This extends the service life of filter element 17 and can quickly restore filtration performance, improve working efficiency, and reduce maintenance costs by eliminating the need for frequent disassembly of filter element 17.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a bidirectional motor 9 is fixedly installed on the top of the first partition plate 15. A fixing rod 10 is fixedly connected to the output ends on both sides of the bidirectional motor 9. A first bevel gear 11 is provided on the side of the fixing rod 10. A stirring rod 13 is provided through the top of the first partition plate 15. A second bevel gear 12 is provided on the top of the stirring rod 13. The second bevel gear 12 and the first bevel gear 11 are meshed together. A mixing paddle 14 is provided on the outside of the stirring rod 13. The bottom of the stirring rod 13 is rotatably connected to the second partition plate 16. A filter element 17 is provided on the top of the first partition plate 15. A screwing member 18 is provided on the top of the filter element 17. A threaded part 24 is provided on the outside of the filter element 17 near the screwing member 18. The threaded part 24 is threadedly connected to the first partition plate 15. A through hole is provided through the top of the second partition plate 16. The through hole abuts against the liquid outlet of the filter element 17.

[0031] The system incorporates a bidirectional motor 9, a fixed rod 10, a first conical gear 11, a second conical gear 12, a stirring rod 13, and a mixing paddle 14. This system mixes and stirs the reactants entering the purification cylinder 1, ensuring uniform particle dispersion and enabling rapid filtration with improved efficiency. Furthermore, the stirring process increases the liquid velocity within the purification cylinder 1, causing impurities adhering to the surface of the filter element 17 to detach, reducing surface resistance and further enhancing filtration speed. During operation, the bidirectional motor 9 is switched on, controlling the fixed rod 10 and the first conical gear 11 to rotate. Simultaneously, the first conical gear 11, through the second conical gear 12, drives the stirring rod 13 to rotate, allowing the mixing paddle 14 to thoroughly mix the reactants within the purification cylinder 1, thereby accelerating the reaction process and improving filtration efficiency.

[0032] The working process of this utility model is as follows: When using the purification device designed in this scheme for easy filtration, during filtration, first turn on the switch of the bidirectional motor 9, then close the third valve 22 and the first valve 6. Add the reactants through the inlet pipe 2. The bidirectional motor 9 controls the fixed rod 10 and the first bevel gear 11 to rotate. At the same time, the first bevel gear 11 drives the stirring rod 13 to rotate through the second bevel gear 12, thereby making the mixing paddle 14 fully mix the reactants in the purification cylinder 1. After filtration at 17, the reactants are then... The Y-shaped connecting pipe 19 and the straight connecting pipe 20 finally flow out from the outlet pipe 3. When the filter element 17 needs to be cleaned, both the second valve 21 and the first valve 6 are closed. The water inlet pipe 4 is connected to the water pipe, and then the water pump 23 is started. The water pump 23 delivers water along the straight connecting pipe 20 and the Y-shaped connecting pipe 19 to the inside of the filter element 17 to backwash the impurities attached to the surface of the filter element 17. Then, the first valve 6 is opened, so that the waste liquid flows out from the waste liquid discharge pipe 5, which achieves a rapid cleaning effect and allows the filter element 17 to quickly restore its filtration performance.
