Description

Technical Field

[0001] This utility model relates to the field of filtration processing technology, specifically to a continuous filtration device for purifying dehydroepiandrosterone. Background Technology

[0002] Solid-phase extraction (SPE) is a sample pretreatment technique based on liquid-solid chromatography theory, primarily used for the separation, purification, and concentration of target compounds in samples. Its principle involves the selective adsorption and elution of target analytes from interfering components, reducing sample pretreatment steps and improving analytical sensitivity. Compared to traditional liquid-liquid extraction, SPE is simpler to operate, saves time and effort, and effectively improves analyte recovery. SPE is widely used in pharmaceuticals, food, environment, commodity inspection, and chemical industries, and has become a standard method in many national and industry analytical standards. The extraction column is a key tool in SPE technology for extracting, separating, and concentrating samples. Common solid-phase extraction columns typically consist of a polypropylene column tube, sieve plates, and adsorbent. Adsorbents are diverse, including silica gel matrix, polymer matrix, and inorganic adsorbent materials. The extraction column achieves sample purification and enrichment through the selective adsorption of the target substance by the stationary phase. The operation steps include activation, sample loading, rinsing, and elution; the flow rate control at each step is crucial to the experimental results.

[0003] A search revealed that CN220745418U discloses a centralized continuous wastewater filtration device, belonging to the technical field of wastewater filtration equipment. The device includes a filter tank with a support frame fixedly connected to its bottom. Vertically arranged filter screen cylinders are rotatably connected to the inner walls of both ends of the filter tank via bearing rings. An inlet valve port communicating with the filter screen cylinders is fixedly connected to the upper side of the filter tank, and a drain pipe communicating with the filter screen cylinders is fixedly connected to the bottom of the filter tank. An outlet valve port is connected to one side of the drain pipe. In this invention, a rotating mechanism drives the filter screen cylinders to rotate, allowing a backwashing mechanism to thoroughly backwash the filter screen cylinders. This ingenious structure reduces piping and facilitates later maintenance. Furthermore, the rotation of the filter screen cylinders agitates the water, enabling brushing and improving the cleaning effect. A discharge mechanism facilitates efficient and rapid sludge removal, ensuring continuous centralized wastewater filtration.

[0004] The aforementioned centralized continuous filtration equipment for wastewater enhances the backwashing effect by rotating and stirring the filter cartridge, but it may not thoroughly clean highly viscous residues (such as dehydroepiandrosterone crystals) from the chemical purification process. At the same time, this design relies on the rotation of the filter cartridge to achieve backwashing, which requires the configuration of complex components such as bearings and rotary motors. Long-term operation is prone to wear and frequent maintenance. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0050] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 This utility model provides a technical solution: a continuous filtration device for purifying dehydroepiandrosterone, including a main component 1, the main component 1 including a processing seat 11;

[0051] A filter cartridge 15 is fixedly connected to the center of the processing base 11;

[0052] A clamping cavity 16 is formed inside the processing base 11 and located outside the filter cartridge 15;

[0053] A rinsing assembly 2, installed inside and outside the processing base 11, is used to filter residues inside the filter cartridge 15 for rinsing.

[0054] An inner scraper assembly 3, located inside and outside the processing base 11, is used to clean and filter residues inside the filter cartridge 15.

[0055] This design solves the problems of existing technologies, such as the reliance on water rinsing for cleaning, insufficient treatment of highly adhesive residues, and the complex structure and high maintenance costs of rotating filter cartridges.

[0056] Please see Figure 1 The main component 1 also includes:

[0057] The feed port 12 is fixedly connected to the top of the processing base 11;

[0058] The feed inlet 12 corresponds to the inner side of the filter cartridge 15;

[0059] The filter medium can be easily injected into the processing seat 11, located inside the filter cartridge 15, through the feed port 12, and wait for filtration.

[0060] Please see Figure 2 The main component 1 also includes:

[0061] The second row of outlets 14 is fixedly connected to the bottom of the machining base 11;

[0062] The second outlet 14 corresponds to the inner side of the filter cartridge 15;

[0063] Impurities filtered and intercepted by the filter cartridge 15 can be discharged from the bottom of the processing seat 11 at the second outlet 14.

[0064] Please see Figure 2 The main component 1 also includes:

[0065] The first row of outlets 13 is fixedly connected to the inner side of the processing base 11;

[0066] The first outlet 13 corresponds to the position of the clamping cavity 16;

[0067] After being filtered by the filter cartridge 15, the medium flows into the clamping cavity 16 and is discharged outward through the first outlet 13.

[0068] Please see Figure 3 and Figure 4 The internal scraper assembly 3 includes:

[0069] A forward and reverse motor 31 is fixedly installed on the outside of the machining base 11;

[0070] A threaded rod 311 is fixedly connected to the output end of the forward and reverse motor 31;

[0071] This design eliminates the rotating filter cartridge and adopts a fixed filter cartridge 15 with a linearly moving cleaning blade 331. Only the forward and reverse motors 31 are needed to drive the threaded rod 311, resulting in a more compact structure, fewer dynamic parts, and lower maintenance costs.

[0072] The internal scraper assembly 3 also includes:

[0073] A slide 32 is threadedly connected to the outside of the threaded rod 311;

[0074] A U-shaped connecting rod 321 is fixedly connected to the top side of the slide block 32;

[0078] The cleaning scraper 331 is fixedly connected to the upper and lower outer sides of the ring seat 33;

[0079] The scraper blade 331 is in contact with the inner side of the filter cartridge 15;

[0080] When the forward and reverse motor 31 drives the threaded rod 311 to rotate in both directions, the slide 32, which is threaded to the outside of the threaded rod 311, will drive the ring seat 33 to move vertically back and forth inside the filter cartridge 15 through the U-shaped connecting rod 321, and the cleaning scraper 331 on the outside of the ring seat 33 can scrape off the residual impurities on the inner surface of the filter cartridge 15.

[0087] Furthermore, the water pipe 221 is connected to the inside of the ring seat 33;

[0088] The flushing assembly 2 also includes:

[0089] Spray heads 23 are fixedly connected at equal intervals to the outside of the ring seat 33;

[0090] This design removes hard residues by direct contact between the scraper blade 331 and the inner wall of the filter cartridge 15, while the spray head 23 performs directional high-pressure rinsing. This dual action ensures that the filter pores are not clogged, making it suitable for fine purification scenarios.

[0091] When the scraper blade 331 scrapes vertically against the inside of the filter cartridge 15 along with the ring seat 33, the water pump 22 can be started simultaneously, so that the clean water source in the external water tank 21 passes through the connecting water pipe 221 and the ring seat 33 and is sprayed out from the spray head 23 toward the inside of the filter cartridge 15. This design, together with the scraper blade 331, can effectively improve the cleaning power of residual impurities on the inside of the filter cartridge 15.
