Description

Technical Field

[0001] This utility model relates to the field of extraction technology, specifically to an automatic rotary liquid extraction device. Background Technology

[0002] Diatomaceous earth is a biogenic siliceous sedimentary rock formed from the remains of ancient diatoms through geological processes. Its chemical composition is primarily SiO2, often containing small amounts of metal oxides such as Al2O3, Fe2O3, and CaO, as well as organic impurities. It is non-toxic, non-flammable, waterproof, deodorizing, dehumidifying, sound-insulating, and heat-insulating. Diatomaceous earth exhibits excellent thermal and chemical stability and is widely used in the testing and inspection industry. For example, in water quality testing, its porous structure and adsorption properties remove impurities, heavy metal ions, and organic pollutants, ensuring accurate detection. In gas detection, diatomaceous earth acts as a catalyst carrier, loading specific catalysts to catalyze gas reactions, enabling quantitative detection of harmful gases. In the testing of food, pharmaceuticals, leather, and textiles, it serves as a filter aid, assisting in solid-liquid separation, enriching target components, and improving detection sensitivity.

[0003] The applicant's earlier application CN113069791B discloses an automated quantitative filling extraction device and method for diatomaceous earth. This device uses a conveyor belt for sample transport, resulting in a large size, low integration, high manufacturing costs, and a large footprint. Therefore, optimizing the automated diatomaceous earth extraction device is the technical problem this application aims to solve. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes an automatic rotary liquid addition extraction device. This device can rotate and adjust the station to sequentially add diatomaceous earth to multiple extraction instruments. When moved to the automatic liquid addition module, it can rotate and adjust the station to sequentially add reagents to multiple extraction instruments for elution.

[0005] The technical solution of this utility model is as follows:

[0006] An automatic rotary liquid extraction device includes a modular base, an automatic diatomaceous earth filling module at one end of the modular base, an automatic liquid addition module at the other end, and a moving platform module in the middle.

[0007] The mobile platform module includes a translation platform and an extraction rotary platform. The extraction rotary platform is set on the translation platform and is used to drive the extraction rotary platform to move back and forth between the automatic diatomaceous earth filling module and the automatic liquid addition module. Several extraction instruments are placed on the extraction rotary platform to drive each extraction instrument to rotate, thereby controlling each extraction instrument to be aligned with the automatic diatomaceous earth filling module and the automatic liquid addition module.

[0008] In summary, the above technical solution has the following beneficial effects: This application, through the setting of an extraction rotary platform, can accommodate several extraction instruments. When moved to the automatic diatomaceous earth filling module, the station can be rotated and adjusted to sequentially add diatomaceous earth to multiple extraction instruments for column packing. When moved to the automatic liquid addition module, the station can be rotated and adjusted to sequentially add reagents to multiple extraction instruments for elution. This method of moving multiple extraction instruments to add raw materials accelerates the extraction speed, and the entire device has a higher degree of integration and a smaller footprint.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figure 1 As shown, an automatic rotary liquid extraction device includes a module base 10, with an automatic diatomaceous earth filling module 20 at one end and an automatic liquid addition module 30 at the other end, and a moving platform module 40 in the middle. The moving platform module 40 includes a translation platform 41 and an extraction rotary platform 42. The extraction rotary platform 42 is mounted on the translation platform 41 and is used to drive the extraction rotary platform 42 to reciprocate between the automatic diatomaceous earth filling module 20 and the automatic liquid addition module 30. Several extraction instruments are placed on the extraction rotary platform 42 to drive each extraction instrument to rotate, thereby controlling each extraction instrument to be aligned with the automatic diatomaceous earth filling module 20 and the automatic liquid addition module 30. This application utilizes an extraction rotary platform 42, on which multiple extraction instruments can be mounted. When it moves to the automatic diatomaceous earth filling module 20, the station can be rotated and adjusted to sequentially add diatomaceous earth to multiple extraction instruments for column packing. When it moves to the automatic liquid addition module 30, the station can be rotated and adjusted to sequentially add reagents to multiple extraction instruments for elution. This method of moving multiple extraction instruments to add raw materials accelerates the extraction speed, and the entire device has a higher degree of integration and a smaller footprint.

[0021] like Figure 2 and Figure 3 As shown, the translation platform 41 includes a translational force component 411, a slide rail 412, and a sliding disk 413. The slide rail 412 is mounted on the module base 10, and the sliding disk 413 is slidably connected to the slide rail 412. The translational force component 411 is connected to the sliding disk 413 and is used to control the reciprocating movement of the sliding disk 413 between the automatic diatomaceous earth filling module 20 and the automatic liquid adding module 30. Specifically, the translational force component 411 is a translational motor, which is mounted on the module base 10 and connected to the sliding disk 413 via a belt, thereby controlling the reciprocating translation of the sliding disk 413 on the slide rail 412. Alternatively, the translational motor can be combined with gears 354 and racks 321 to control the translation. Or, the translational force component 411 can be a telescopic rod, a cylinder, or an electric cylinder, etc., to control the translation.

[0022] The extraction rotating platform 42 includes a first rotating power component 421, a lower rotating disk 422, an upper rotating disk 423, and a rotating column 424, all mounted on a translation platform 41. The lower rotating disk 422 is rotatably connected to the translation platform 41, and has several lower fixed positions 4221 for placing collection bottles. The upper rotating disk 423 is mounted on the lower rotating disk via the rotating column 424, and has several upper fixed positions 4231 for placing extraction columns. The upper fixed positions 4231 and lower fixed positions 4221 correspond one-to-one, ensuring a one-to-one correspondence between the extraction column and the collection bottle. The first rotating power component 421 is connected to the lower rotating disk 422 and drives the lower rotating disk 422, upper rotating disk 423, and rotating column 424 to rotate together. Specifically, the collection bottle is a round-bottom flask, but it can also be other experimental bottles used for collecting liquids. The round-bottom flask and extraction column constitute the extraction apparatus. Correspondingly, the lower fixing position 4221 is a cylindrical fixing component or a semi-circular groove structure. The upper rotating disk 423 includes an upper support disk and an upper fixing disk. The upper fixing disk has a large hole for the liquid inlet at the top of the extraction column to pass through, and the upper support disk has a small hole for the liquid outlet at the bottom of the extraction column to pass through. The small hole does not allow the liquid inlet at the top of the extraction column to pass through, thus fixing the extraction column. The liquid outlet at the bottom of the extraction column is inserted into the corresponding round-bottom flask. Specifically, the first rotating power component 421 is a first rotating motor, which is mounted on the translation platform 41 and connected to the lower rotating disk 422 via a belt, thereby driving the lower rotating disk 422 to rotate. Of course, the lower rotating disk 422 can also be driven to rotate by a reducer and gear 354, etc.

[0023] like Figures 4-7As shown, the automatic diatomaceous earth filling module 20 includes a feeding base 21, a storage hopper 22, a metering rotary table 23, and a feeding tray 24. The storage hopper 22, metering rotary table 23, and feeding tray 24 are all mounted on the feeding base 21. The storage hopper 22 stores diatomaceous earth and is equipped with a door cover 221 for observation of the diatomaceous earth content and timely replenishment. A loading tray 222 is located at the bottom of the storage hopper 22, featuring a sealing area 223 and several loading ports 224. Several metering cups 231 are installed inside the metering rotary table 23, with the upper end of each cup 231 contacting the loading tray 222. The metering rotary table 23 rotates the metering cups 231; when a cup 231 rotates to a loading port 224, diatomaceous earth enters the cup. The feeding tray 24 is positioned below the metering cup 231 and directly opposite the sealing area 223 of the filling tray 222. When the metering cup 231 rotates to the sealing area 223, the opening above the metering cup 231 is blocked, and the opening below is blocked by the feeding tray 24. A discharge tray 25 is provided below the metering rotary table 23. A feeding port 251 is provided on the discharge tray 25. The feeding port 251 is located below the feeding tray 24. The feeding tray 24 is slidably connected to the metering rotary table. When the feeding tray 24 is pulled out, the lower opening of the metering cup 231 communicates with the feeding port 251.

[0024] A vibrator is installed on the feeding tray 24. Specifically, the door cover 221 can be installed on the top, front, or both of the material storage hopper 22, so as to facilitate opening the material storage hopper 22 from various angles, making it convenient to observe the usage of diatomaceous earth material in the hopper and replenish the diatomaceous earth material.

[0025] Specifically, the quantitative rotating platform 23 is circular, and 12 quantitative cups 231 are arranged around it. Each quantitative cup 231 can hold 20g of diatomaceous earth material. The movement of the quantitative rotating platform 23 ensures that the 12 quantitative cups 231 are evenly filled with diatomaceous earth material. The feeding tray 24 includes a feeding power component and an insert plate. The feeding power component and the insert plate are connected and used to control the movement of the insert plate to close or open the feeding port 251. When feeding is needed, the feeding power component controls the feeding port 251 to open, the vibrator vibrates, and 20g of diatomaceous earth flows from the feeding hole into the extraction column placed below. Specifically, the feeding power component is a control component that can control extension and retraction, such as a cylinder or electromagnet.

[0026] like Figure 8 and Figure 9As shown, the automatic liquid dispensing module 30 includes a liquid dispensing base 31, an actuator 32, a liquid dispensing component 33, and a liquid dispensing rotary table 34. The actuator 32 and the liquid dispensing component 33 are fixedly mounted on the liquid dispensing base 31. The liquid dispensing rotary table 34 is rotatably connected to the liquid dispensing base 31, and several reactor assemblies 35 are mounted on the liquid dispensing rotary table 34 to drive each reactor assembly 35 to rotate to the actuator 32 and the liquid dispensing component 33. One end of the liquid dispensing component 33 is connected to a liquid dispensing container, and the other end extends to the reactor assembly 35 to add the reagent from the liquid dispensing container into the reactor assembly 35. The actuator 32 is used to control the tilting of the reactor assembly 35, thereby pouring out the reagent from the reactor assembly 35. The actuator 32 is an actuating cylinder used to control the extension and retraction of the rack 321, thereby controlling the rotation of the reactor assembly 35 through the gear 354 on the reactor assembly 35. The liquid addition component 33 is a liquid addition pump. The suction port of the liquid addition pump extends into the reagent container, and the outlet of the other end extends into the path of the reaction tube 351 and is aligned with the mouth of the reaction tube 351. The liquid addition pump repeatedly adds liquid to rinse the sample in the reactor. The liquid addition pump can control the liquid addition and rinsing volume of 20 mL per cycle. The liquid addition rotary table 34 is used to control the overall rotation of the reactor assembly 35 set on it and adjust the corresponding liquid addition position.

[0027] The reactor assembly 35 includes a reaction tube 351, a rotating block 352, and a fixed block 353. The fixed block 353 is mounted on the liquid addition rotary table 34. The rotating block 352 and the fixed block 353 are rotatably connected. The reaction tube 351 is mounted on the rotating block 352, and a gear 354 is mounted on the rotating block 352. A rack 321 is mounted on the actuating element 32. When the actuating element 32 extends, the rack 321 engages the gear 354, causing the opening of the reaction tube 351 to tilt downwards via the rotating block 352. When the actuating element 32 retracts, the rack 321 engages the gear, causing the opening of the reaction tube 351 to tilt upwards via the rotating block 352. When the actuating element 32 is fully retracted, the rack 321 and the gear 354 disengage. The gears 354 on at least two rotating blocks 352 are coaxially connected for joint rotation. Multiple reactor components 35 are connected in series, allowing the actuator 32 to add liquid to multiple extraction columns with a single operation, thereby improving work efficiency. Correspondingly, two liquid adding components 33 are also provided.

[0028] A funnel 355 is provided on the fixed block 353. The reagent is added to the extraction instrument through the reaction tube 351 via the funnel 355. When the reaction tube 351 is tilted, it is impossible to accurately add the reagent to the extraction instrument. The funnel 355 can expand the range of reagent collection, allowing the liquid in the reaction tube 351 to be better concentrated before flowing into the extraction column.

[0029] The actuator 32 engages with the gear 354 on the support via the rack 321 fixed on the cylinder push plate, causing the reactor to tilt and pour the reagent for rinsing the sample. The reagent flows through the triangular funnel 355 into the extraction column at the corresponding station below. The liquid addition cylinder is used to assist in controlling the liquid addition pump to repeatedly add liquid to rinse the sample in the reactor. The liquid addition pump can control the liquid addition and rinsing volume to be 20 mL at a time. The liquid addition rotary table 34 is used to control the overall rotation of the support that fixes the reactor and adjust the corresponding liquid addition station.

[0030] The reactor consists of an actuating cylinder, a liquid-adding cylinder, and a liquid-adding rotating platform 34. The actuating cylinder engages with a gear 354 on the support via a rack 321 fixed to the cylinder push plate, causing the reactor to tilt and pour out the reagent for rinsing the sample. The reagent flows through a triangular funnel 355 into the extraction column at the corresponding station below. The liquid-adding cylinder is used to assist in controlling the liquid-adding pump to repeatedly add liquid to rinse the sample in the reactor. The liquid-adding pump can control the liquid-adding rinse volume to be 20 mL per cycle. The liquid-adding rotating platform 34 is used to control the overall rotation of the support that fixes the reactor and adjust the corresponding liquid-adding station.

[0031] A drip ring groove 36 is provided on the liquid addition base 31. The drip ring groove 36 is located at the annular path of the funnel 355 on the liquid addition rotary table 34. The drip ring groove 36 has a drip outlet 361 at the reactor assembly 35 corresponding to the actuator 32. The drip ring groove 36 can collect the reagent remaining on the funnel 355, avoiding reagent pollution to the environment.

[0032] The working principle is as follows: The sliding plate 413 drives the extraction rotating platform 42 to move left to below the automatic diatomaceous earth filling module 20. After the workstation is in position, the extraction rotating platform 42 is controlled to rotate, sequentially filling the extraction columns of 20 workstations with 20g of diatomaceous earth powder. After the diatomaceous earth powder is filled, the sliding plate 413 drives the extraction rotating platform 42 to move right. During this process, the reactor containing the pyrolysis solution needs to be fixed on the fixed support of the automatic liquid addition module 30. After the extraction rotating platform 42 moves right to the correct workstation, the automatic liquid addition module 30 starts its first operation, pouring the pyrolysis solution in the reactor into the extraction column containing diatomaceous earth. After standing for 15 minutes, the liquid addition cylinder on the automatic liquid addition module 30 operates to perform the first liquid addition flush on the reactor after the pyrolysis solution has been poured out. After the 15-minute standing time, the first liquid addition flush is performed. The washing reagent is poured into the extraction column containing diatomaceous earth. After the first flushing is completed, the second flushing is immediately performed and the flushing liquid in the reactor is poured out. After the second flushing is completed, the extraction rotating platform 42 is activated, and the system switches to the next station to perform the first flushing action. During this time, the previous station performs the third flushing. After the second flushing of the next station is completed, the system switches to the next station and repeats the actions of the previous set of stations. The flushing of 20 sets of stations is completed in sequence. The round-bottom flask used to collect reagents at the bottom of the extraction column is removed for subsequent processing and analysis.
