Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a static separation device for extracting nano-selenium synthesized by microorganisms. Background Technology

[0002] In the process of microbial synthesis of selenium nanoparticles, the synthesized selenium nanoparticles need to be extracted and separated from the culture medium. To efficiently and economically extract selenium nanoparticles from large-scale microbial cultures, a static separation device has been developed. This device uses physical means to separate selenium nanoparticles from the culture medium, and it has broad application prospects in environmental protection, medicine, agriculture, and other fields. Selenium nanoparticles possess strong biological activity and antioxidant properties, making them a nanomaterial with great potential.

[0003] Traditional static separation devices typically rely on gravity settling during the collection of nano-selenium. However, nano-selenium particles are prone to agglomeration or dispersion, causing some precipitate to adhere to the inner wall or corners of the container, making complete collection difficult. Furthermore, the residual liquid in the precipitate requires long-term natural drying or additional drying equipment, which is inefficient and energy-intensive. In traditional devices, the discharge of the supernatant usually requires manual pouring or manual operation of pumps, which is not only inefficient but may also lead to liquid leakage or intrusion of external impurities due to improper operation, affecting product quality.

[0012] As a further improvement to the above solution, the rotating frame is rotatably connected inside the connecting frame, the rotating rod is rotatably connected inside the connecting sleeve, and the connecting sleeve is rotatably connected to the bottom of the fixed plate.

[0013] Through the above technical solution, the structural design of rotating connection between rotating frame and connecting frame, and rotating connection between rotating rod and connecting sleeve, drives stable rotation of rotating frame and smooth liquid discharge, thereby achieving low friction loss and high stability of equipment.

[0017] Through the above technical solution, the rapid transfer and storage of liquids are achieved by the coordinated action of water pumps, connecting pipes and telescopic hoses, improving separation efficiency, reducing manual intervention and enhancing the automation level of the equipment.

[0018] As a further improvement to the above solution, the connecting pipe is fixedly connected to the outside of the water pump, and the cover plate is inserted into the inside of the storage shell.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention constrains the movement trajectory of nano-selenium particles through a guide ring, ensuring their smooth entry into the rotating frame and preventing the dispersion or residue of precipitates. Simultaneously, the rotating frame rotates under the drive of a servo motor and a rotating rod, using centrifugal force to further discharge the liquid from the precipitates. This design not only improves the dryness of nano-selenium but also reduces the impact of liquid residue on subsequent processing. Through the synergistic effect of the guide ring and the rotating frame, efficient separation and drying of nano-selenium are achieved, improving the purity and quality of the product while reducing the workload of subsequent drying processes.

[0021] This invention uses a water pump connecting pipe to draw out the clear liquid from the upper layer of the storage shell and then transports it to the storage tank via a telescopic hose. This process avoids the cumbersome nature of manual operation. At the same time, the filter screen prevents the discharge of nano-selenium particles from inside the rotating frame. Furthermore, the design of the first discharge pipe further simplifies the liquid discharge process. Through the coordinated action of the water pump, connecting pipe, and telescopic hose, rapid transfer and storage of the liquid are achieved, improving separation efficiency while reducing manual intervention and enhancing the automation level and ease of operation of the equipment.

It also includes:

[0031] The filter mechanism 2 includes a guide ring 201 fixedly connected inside the storage housing 12, and a filter screen 203 is provided at the bottom of the guide ring 201.

[0032] The extraction mechanism 3 includes a fixed frame 301 fixedly connected to the outside of the storage housing 12, and a cover plate 303 is provided at the bottom of the fixed frame 301.

[0033] The bottom of the guide ring 201 is rotatably connected to a rotating frame 202, a filter screen 203 is fixedly connected inside the rotating frame 202, a fixing plate 204 is fixedly connected inside the rotating frame 202, and a connecting frame 205 is fixedly connected inside the storage shell 12.

[0034] A servo motor 206 is fixedly connected to the bottom inner wall of the base 1, and a rotating rod 207 is fixedly connected to the output end of the servo motor 206. A connecting sleeve 208 is fixedly connected to the bottom inner wall of the discharge housing 11.

[0035] The rotating frame 202 is rotatably connected inside the connecting frame 205, the rotating rod 207 is rotatably connected inside the connecting sleeve 208, and the connecting sleeve 208 is rotatably connected to the bottom of the fixing plate 204.

[0036] A hydraulic rod 302 is fixedly connected to the bottom of the fixed frame 301. A cover plate 303 is fixedly connected to the bottom end of the hydraulic rod 302. A water pump 304 is fixedly connected to the top of the cover plate 303. A feed inlet 305 is fixedly connected to the inside of the cover plate 303.

[0037] The cover plate 303 is internally fixedly connected to a connecting pipe 306, the bottom of the connecting pipe 306 is fixedly connected to a telescopic hose 307, the telescopic hose 307 is externally fixedly connected to a storage tank 308, and the storage tank 308 is externally fixedly connected to a second discharge pipe 309.

[0038] The connecting pipe 306 is fixedly connected to the outside of the water pump 304, and the cover plate 303 is inserted into the inside of the storage shell 12.

[0039] The implementation principle of the static separation device for extracting nano-selenium synthesized by microorganisms in this application embodiment is as follows: When in use, the suspension containing nano-selenium synthesized by microorganisms is first injected into the interior of the storage shell 12 through the feed port 305. The suspension settles naturally under the action of gravity, and the nano-selenium particles gradually settle to the bottom of the storage shell 12, while the liquid part remains on the upper layer. At this time, the guide ring 201 plays a guiding role, so that the nano-selenium smoothly enters the interior of the rotating frame 202 under the constraint of gravity and the guide ring 201. As the sedimentation process proceeds, the clear liquid is filtered through the filter screen 203 and then discharged into the cavity formed by the discharge shell 11 and the storage shell 12. The filter screen 203 is set to prevent the nano-selenium particles from being discharged.

[0040] After filtration, the water pump 304 is started, and the clear liquid in the upper part of the storage shell 12 is sucked out through the connecting pipe 306 and transported to the storage tank 308 through the telescopic hose 307. The suction action of the water pump 304 makes the liquid transfer process fast and efficient. The filtered liquid is discharged from the discharge shell 11 through the first discharge pipe 13, completing the separation and collection of the liquid. At the same time, the servo motor 206 can be started, and the fixed plate 204 is driven to rotate through the rotating rod 207, thereby driving the precipitate nano-selenium inside the rotating frame 202 to rotate. During the rotation, the precipitate inside the guide ring 201 is subjected to centrifugal force, further discharging the residual liquid and improving the dryness of the nano-selenium.

[0041] After the liquid is drained, the hydraulic rod 302 is activated to retract and move the cover plate 303 upward, opening the top opening of the storage housing 12. At this time, the precipitated nano-selenium inside the rotating frame 202 can be easily collected. After collection, the cover plate 303 is closed again, and the equipment returns to its initial state for easy use next time.

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.
