Description

Technical Field

[0001] This application relates to the field of water sample pretreatment technology, and in particular to a microbial water sample pretreatment processor. Background Technology

[0002] Water quality testing is an important means of assessing water quality and monitoring the aquatic environment. Before conducting water quality testing, water samples usually need to be pretreated to eliminate or reduce interfering substances in the water samples, thereby improving the accuracy and reliability of the testing.

[0003] Wastewater discharged from factories or restaurants inevitably contains oily or emulsified substances. Current pretreatment methods for such samples typically involve placing the test tube containing the water sample under a microscope to observe the droplet size and distribution, thus determining whether the sample contains emulsified or oily substances. If it contains emulsified substances, a clean pipette is used to extract an emulsion reagent and add it to the sample. If it contains oily substances, a clean pipette is used to extract an oil-water reagent and add it to the sample. After all samples have been treated, they are left to stand for 15 to 20 minutes to allow for stratification. Then, a new clean pipette is used to remove the emulsified waste liquid, and a clean pipette is used to remove the oily waste liquid. The samples are then transferred to a waste liquid container and finally centrifuged. After centrifugation, the samples are ready for further pretreatment for subsequent experiments.

[0004] However, when using the reagents, the entire process of the above method requires manual operation by the experimenter. When there are many water samples to be processed, the overall processing efficiency is low, and there is room for improvement. Utility Model Content

[0005] To address the problem that existing water sample pretreatment processes require manual operation and have low processing efficiency, this application provides a microbial water sample preprocessor.

[0006] This application provides a microbial water sample preprocessor, which adopts the following technical solution:

[0007] A microbial water sample preprocessor includes a frame, and a water sample placement area, a clean pipette storage box, a water-emulsion reagent kit, a water-oil reagent kit, a waste liquid recycling box, a waste pipette recycling box, and a centrifuge, all spaced apart on the frame. On one side of the frame, there are spaced-apart detection mechanisms for detecting water samples, reagent aspiration mechanisms for connecting clean pipettes and driving the clean pipettes to aspirate reagents, and pipette retraction assemblies for driving clean pipettes to retract from the reagent aspiration mechanisms. The frame is provided with a sliding seat and a first driving assembly for sliding the sliding seat. The sliding seat is provided with a clamping mechanism for holding the detection mechanism or the reagent aspiration mechanism, and a water sample moving mechanism for moving test tubes containing water samples from the water sample placement area to the centrifuge. The frame is also provided with a control panel for controlling the operation of the device and displaying the processing results.

[0008] By adopting the above technical solution, during use, the experimenter only needs to place several test tubes containing water samples to be treated one by one into the water sample placement area, and then start the device through the control panel. The detection mechanism can determine the placement position of the emulsion-containing water sample and the oil-containing water sample. Then, through the cooperation of the reagent aspiration mechanism and the pipette retraction assembly, different clean pipettes can be connected to inject the emulsion reagent into the emulsion-containing water sample, the oil-water reagent into the oil-containing water sample, and then the waste liquid in the emulsion-containing water sample and the oil-containing water sample can be removed in sequence and injected into the waste liquid recycling box. At the same time, the used pipettes are retracted into the waste pipette recycling box. Finally, the water sample moving mechanism puts the treated water sample into the centrifuge for centrifugation, thus completing the water sample pretreatment process. The overall operation is simple and convenient, and the pretreatment efficiency is also improved.

[0009] Preferably, the frame includes a base, a mounting bracket disposed on the base, and a first drive electric cylinder disposed on the base for driving the mounting bracket to rise and fall. The water sample placement area, clean pipette storage box, water-emulsion reagent kit, water-oil reagent kit, waste liquid recycling box, waste pipette recycling box, and centrifuge are all disposed on the base. The detection mechanism, reagent aspiration mechanism, sliding seat, and first drive assembly are all disposed on the mounting bracket.

[0010] By adopting the above technical solution, when in use, the first drive electric cylinder drives the mounting frame to rise and fall, thereby moving the detection mechanism, reagent aspiration mechanism, sliding seat, and first drive component away from the seat body, which makes it convenient for the experimenter to change the water sample in the water sample placement area. At the same time, it drives the reagent aspiration mechanism to cooperate with the clean pipette, thereby completing the operation of injecting the corresponding reagent into the water sample or aspirating the waste liquid.

[0011] Preferably, the sliding seat is provided with a sliding block and a first driving member for driving the sliding block to slide. The sliding direction of the sliding block, the sliding direction of the sliding seat, and the sliding direction of the mounting frame are perpendicular to each other. The clamping mechanism and the water sample moving mechanism are provided on the sliding block.

[0012] By adopting the above technical solution, the clamping mechanism and the water sample moving mechanism can move in three dimensions through the coordinated use of the sliding block, the sliding seat and the mounting frame.

[0013] Preferably, the clamping mechanism includes a fixed base fixed on the sliding block, a first gripper disposed on the fixed base for clamping the detection mechanism or reagent aspiration mechanism, and a second drive assembly for driving the first gripper to clamp.

[0014] By adopting the above technical solution, when in use, the first gripper is opened and closed by the second driving component, thereby realizing the separate clamping of the reagent aspiration mechanism or the tube retraction assembly.

[0015] Preferably, the frame has two connecting seats, the detection mechanism is installed on one of the connecting seats, and the reagent aspiration mechanism and the tube retraction assembly are both installed on the other connecting seat. The connecting seats are configured to cooperate with the clamping mechanism.

[0016] By adopting the above technical solution, when in use, the connection seat ensures that even when the reagent aspiration mechanism and the pipette retraction assembly have different structures, they can still cooperate with the clamping mechanism. This allows the clamping mechanism to clamp the reagent aspiration mechanism or the pipette retraction assembly to complete the corresponding operation under different usage conditions.

[0017] Preferably, the detection mechanism includes an industrial camera mounted on a connector, the industrial camera being electrically connected to a control panel.

[0018] By adopting the above technical solution, when in use, an industrial camera is used to detect water samples, and the detection results are sent to the control panel as electrical signals. This makes it easy for experimental personnel to observe and record the quantity and corresponding location of milky and oily water samples in the detected water samples, so as to facilitate subsequent experiments.

[0019] Preferably, the reagent aspiration mechanism includes a suction needle fixed on a connecting seat and a second driving member disposed on the connecting seat for driving the suction needle to aspirate the reagent, wherein the outlet of the suction needle is interference-fitted with a clean pipette.

[0020] By adopting the above technical solution, when the aspiration needle is connected to the clean pipette, the liquid can be drawn into the pipette through the cooperation of the second driving component and the aspiration needle.

[0021] Preferably, the suction tube assembly includes a second drive cylinder mounted on a connecting seat and a push plate fixed on the piston rod of the second drive cylinder, the push plate engaging with the clean suction tube.

[0022] By adopting the above technical solution, when it is necessary to replace the pipette, simply activate the second drive cylinder to slide the push plate, thereby pushing the pipette away from the reagent aspiration mechanism, thus realizing the removal of the pipette and facilitating the connection of subsequent clean pipettes.

[0023] Preferably, the frame is covered with a protective shell made of transparent material, the control panel is located on the outside of the protective shell, and the protective shell is provided with an opening and closing door.

[0024] By adopting the above technical solution, the transparent protective shell not only protects the entire device and ensures its normal operation, but also makes it easier for test personnel to observe the device's operating status, making it more convenient to use.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The experimenter only needs to place several test tubes containing water samples to be processed into the water sample placement area one by one, and then start the device through the control panel. The detection mechanism can determine the placement position of the milk-containing water sample and the oil-containing water sample. With the help of the reagent aspiration mechanism, the suction tube assembly and the water sample moving mechanism, the pretreatment process of the water sample can be completed. The overall operation is simple and convenient, and the pretreatment efficiency is also improved.

[0027] 2. By using the sliding block, sliding seat and mounting frame in combination, the clamping mechanism and water sample moving mechanism can move in three dimensions, thereby ensuring the accuracy of the water sample pretreatment process;

[0028] 3. By setting up a protective shell made of transparent material, it is convenient for staff to observe the pretreatment process, while also protecting the device during operation and avoiding interference from the external environment. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.

[0038] This application discloses a microbial water sample preprocessor.

[0039] Reference Figure 1 and Figure 2 A microbial water sample preprocessor includes a frame 1, a water sample placement area 2, a clean pipette storage box 3, a water-emulsion reagent kit 4, a water-oil reagent kit 5, a waste liquid recycling box 6, a waste pipette recycling box 7, and a centrifuge 8. The frame 1 includes a horizontally placed base 11, a mounting frame 12, and a first drive cylinder 13. In this embodiment, both the base 11 and the mounting frame 12 are rectangular, with the mounting frame 12 positioned above the base 11. The first drive cylinder 13 is mounted on the base 11, and its piston rod is fixedly connected to the mounting frame 12. That is, during use, the vertical lifting and lowering of the mounting frame 12 is achieved by the extension and retraction of the piston rod of the first drive cylinder 13.

[0040] Reference Figure 1 and Figure 2 In this embodiment, the first drive cylinder 13 is preferably configured as two, and both first drive cylinders 13 are located on the left side of the base 11 in the length direction. The two first drive cylinders 13 are respectively connected to one end of the mounting frame 12 in the width direction. That is, in use, the mounting frame 12 is lifted and lowered by the joint drive of the two first drive cylinders 13. In addition, an auxiliary lifting rod is provided on the other side of the base 11 in the length direction. The auxiliary lifting rod is used to ensure the stability of the mounting frame 12 in the lifting and lowering process. In this embodiment, a gas spring structure can be used.

[0041] Reference Figure 1 and Figure 2 In this application, the water sample placement area 2, the clean pipette storage box 3, the water-emulsion reagent kit 4, the water-oil reagent kit 5, the waste liquid recycling box 6, the waste pipette recycling box 7, and the centrifuge 8 are all mounted on the base 11. The water sample placement area 2 is used to place test tubes containing water samples to be tested. In this embodiment, the water sample placement area 2 is a rectangular block area, and the test tubes on it are also arranged in a rectangular array. The clean pipette storage box 3, the water-emulsion reagent kit 4, the water-oil reagent kit 5, the waste liquid recycling box 6, and the waste pipette recycling box 7 are spaced apart on the front and back sides of the water sample placement area 2. The centrifuge 8 is located on the right side of the water sample placement area 2. This arrangement facilitates the overall operation of the device.

[0042] Reference Figure 1 and Figure 2 A protective shell 80 is provided on the base 11. In this application, the protective shell 80 is made of transparent material. The protective shell 80 is provided with an opening and closing door for easy storage of samples by the experimenter. The mounting rack 12, water sample placement area 2, clean pipette storage box 3, water-emulsion reagent kit 4, water-oil reagent kit 5, waste liquid recycling box 6, waste pipette recycling box 7, and centrifuge 8 are all placed inside the protective shell 80. A control panel 70 is also installed outside the protective shell 80. During use, the transparent protective shell 80 provides overall protection for the device, avoiding interference from the external environment in the water sample pretreatment process, ensuring the accuracy of the pretreatment results, and also facilitating the experimenter to observe and control the operation of the device from outside the protective shell 80.

[0043] Reference Figure 2 and Figure 3A sliding seat 30 and a first drive assembly 40 are provided on the mounting frame 12. The first drive assembly 40 is used to drive the sliding seat 30 to slide along the length of the mounting frame 12. The first drive assembly 40 includes a one-way lead screw 401 and a first drive motor 402. The one-way lead screw 401 is rotatably connected to the mounting frame 12, and the first drive motor 402 is fixed to the mounting frame 12 by bolts. The output shaft of the first drive motor 402 is coaxially fixedly connected to the one-way lead screw 401. The first drive motor 402 is electrically connected to the control panel 70. A threaded sleeve is fixedly connected to the sliding seat 30, and the threaded sleeve is threadedly engaged with the one-way lead screw 401. In use, the one-way lead screw 401 is driven to rotate by the rotation of the output shaft of the first drive motor 402. When the one-way lead screw 401 rotates, the sliding seat 30 can be driven to slide under the engagement of the threaded sleeve.

[0044] Reference Figure 3 and Figure 4 A sliding block 301 and a first driving member 302 are provided on the sliding base 30. The first driving member 302 is used to drive the sliding block 301 to slide along the width direction of the mounting frame 12. In this application, the first driving member 302 is preferably set as a linear module. The linear module is electrically connected to the control panel 70. The sliding block 301 is fixed to the slide table of the linear module by bolts. A clamping mechanism 50 is provided on the sliding block 301. A bearing seat 15 is bolted to the mounting frame 12. Two connecting seats 14 are arranged at intervals on the bearing seat 15. A detection mechanism 9 is installed on one connecting seat 14, and a reagent aspiration mechanism 10 and a suction tube assembly 20 are installed on the other connecting seat 14. In use, the clamping mechanism 50 is used to clamp the connecting seat 14, thereby driving the detection mechanism 9 or the reagent aspiration mechanism 10 to move.

[0045] Reference Figure 3 and Figure 4 Specifically, two limiting grooves 16 are provided on the support base 15, and the limiting grooves 16 correspond one-to-one with the connecting base 14. The connecting base 14 is embedded in the limiting groove 16. At the same time, in order to ensure the stability of the connecting base 14, a magnetic block can be set in the limiting groove 16 in this embodiment, and a corresponding magnetic block is also set on the connecting base 14. The magnetic attraction between the two magnetic blocks increases the stability of the connecting base 14. In use, the connecting base 14 is clamped by the clamping mechanism 50, which drives the connecting base 14 to disengage from the limiting groove 16. Then, by moving the connecting base 14, the reagent aspiration mechanism 10 and the detection mechanism 9 can be moved.

[0046] Reference Figure 3 and Figure 4The clamping mechanism 50 includes a fixed base 501, a first gripper 502, and a second drive assembly. The fixed base 501 is fixed to the sliding block 301 by bolts. The first gripper 502 includes an upper gripper 5021 and a lower gripper 5022 that are slidably disposed on the fixed base 501. The second drive assembly includes a bidirectional lead screw 503 and a second drive motor 504. The bidirectional lead screw 503 rotates on the fixed base 501, and the second drive motor 504 is mounted on the fixed base 501. The output shaft is coaxially and fixedly connected to the bidirectional lead screw 503. The second drive motor 504 is electrically connected to the control panel 70. The upper clamping block 5021 and the lower clamping block 5022 are respectively set on the opposite side of the thread direction on the bidirectional lead screw 503, and the upper clamping block 5021 and the lower clamping block 5022 are threadedly engaged with the bidirectional lead screw 503. That is, when the bidirectional lead screw 503 rotates, it can drive the upper clamping block 5021 and the lower clamping block 5022 to move closer to each other or further away from each other, thereby realizing the clamping of the first gripper 502 on the connecting seat 14.

[0047] Reference Figure 3 and Figure 4 To ensure a stable connection between the first gripper 502 and the connecting seat 14, an insert 141 is integrally formed on the connecting seat 14. A positioning hole 142 is provided on the insert 141. There are two inserts 141, and the two inserts 141 are spaced apart in the vertical direction. A groove is provided on both the upper gripper 5021 and the lower gripper 5022. A positioning post is fixed on the inner wall of the groove. When the first gripper 502 moves between the two inserts 141, the upper gripper 5021 and the lower gripper 5022 can be driven away from each other by the second drive component until the insert 141 is embedded in the groove and the positioning post is inserted into the positioning hole 142. At this time, the sliding seat 30 can drive the corresponding connecting seat 14 to disengage from the limiting groove 16.

[0048] Reference Figure 3 and Figure 4 The detection mechanism 9 includes an industrial camera 91, which is fixedly mounted on the connecting seat 14. In this embodiment, the industrial camera 91 is preferably a microscope-grade industrial camera. The industrial camera 91 is electrically connected to the control panel 70. In use, when the first gripper 502 is connected to the connecting seat 14 with the industrial camera 91, the sliding seat 30 moves, which can drive the industrial camera 91 to move along the length of the mounting frame 12, thereby detecting the water sample in the water sample placement area 2 to determine whether it is an oily water sample or an emulsion water sample. The final detection result and the corresponding position of the water sample are transmitted to the control panel 70 by an electrical signal. At this time, the experimenter can obtain the quantity and corresponding position of the oily water sample and the emulsion water sample in the tested water sample on the control panel 70.

[0049] Reference Figure 3 and Figure 5The reagent aspiration mechanism 10 includes a liquid aspiration needle 101 and a second driving member 102. The liquid aspiration needle 101 consists of a syringe 1011, a piston, and a push rod 1012. The bottom end of the syringe 1011 is provided with a liquid outlet 1013, which communicates with the inside of the syringe 1011 and is interference-fitted with a clean pipette 90. The piston slides along its own axis inside the syringe 1011, and the bottom end of the push rod 1012 is fixed to the piston. In this application, the second driving member 102 is set as an electric cylinder, which is electrically connected to the control panel 70. The piston rod of the electric cylinder is connected to the top end of the push rod 1012.

[0050] Reference Figure 2 and Figure 5 In use, the sliding block 301, sliding seat 30, and mounting bracket 12 move the reagent aspiration mechanism 10 to directly above the clean pipette storage box 3. Then, the overall lifting and lowering of the mounting bracket 12 causes the liquid outlet 1013 at the bottom of the syringe 1011 to be inserted into the clean pipette 90, thus connecting the clean pipette 90 and the reagent aspiration mechanism 10. When it is necessary to aspirate reagents or waste liquid, the extension of the electric cylinder piston rod drives the push rod 1012 and piston to slide, and in conjunction with the syringe 1011, the liquid can be drawn into the pipette. When it is necessary to discharge liquid, the retraction of the electric cylinder piston rod drives the push rod 1012 and piston to slide in the opposite direction. The process is simple and convenient. When it is necessary to replace the pipette, the pipette connected to the reagent aspiration mechanism 10 can be removed by the pipette retraction assembly 20, which facilitates the subsequent reconnection of the clean pipette 90.

[0051] Reference Figure 2 and Figure 5 The pipette ejection assembly 20 includes a second drive cylinder 201 and a push plate 202. The second drive cylinder 201 is mounted on the connecting seat 14 and is electrically connected to the control panel 70. The push plate 202 is fixedly connected to the piston rod of the second drive cylinder 201. In this embodiment, the piston rod of the second drive cylinder 201 is in a retracted state in the initial state. At this time, the push plate 202 abuts against the bottom end of the syringe 1011 and slides into the liquid outlet 1013. When the clean pipette 90 is connected to the liquid outlet 1013, the push plate 202 is located between the top end of the clean pipette 90 and the bottom end of the syringe 1011. When the piston rod of the second drive cylinder 201 extends, it can drive the push plate 202 to move down, thereby pushing the clean pipette 90 down until the clean pipette 90 is detached from the liquid outlet 1013, thus realizing the operation of ejecting the used pipette.

[0052] Reference Figure 3 and Figure 6A water sample moving mechanism 60 is also provided on the sliding block 301. The water sample moving mechanism 60 is used to move the treated water sample into the centrifuge 8. The water sample moving mechanism 60 includes a third drive electric cylinder 601, a connecting plate 602, and a second gripper. The third drive electric cylinder 601 is inverted. The cylinder body of the third drive electric cylinder 601 is mounted on the sliding block 301. The piston rod of the third drive electric cylinder 601 is bolted to the connecting plate 602. The second gripper is mounted on the connecting plate 602. In this application, the second gripper includes an electric gripper 603 and an arc plate 604 mounted on the electric gripper 603. The electric gripper 603 is electrically connected to the control panel 70. The arc plate 604 is adapted to the test tube. In use, the arc plate 604 ensures the stability of the electric gripper 603 in holding the test tube.

[0053] Reference Figure 2 and Figure 7 The centrifuge 8 is divided into two parts: a body 81 and a cover 82. The cover 82 is hinged to the body 81. The body 81 is provided with a centrifugation zone for placing test tubes. In this application, a fourth drive cylinder 83 is provided on the centrifuge. The cylinder body of the fourth drive cylinder 83 is hinged to the body 81, and the piston rod of the fourth drive cylinder 83 is hinged to the cover 82. The fourth drive cylinder 83 is electrically connected to the control panel 70. During use, the piston rod of the fourth drive cylinder 83 extends and retracts, causing the cover 82 to open or close automatically.

[0054] Reference Figure 2 In this application, in order to ensure the accuracy of the preprocessing process, the sliding positioning of the sliding block 301, the sliding seat 30 and the mounting bracket 12 are all achieved by position sensors. The position sensors are electrically connected to the control panel 70. That is, during use, the accuracy of the movement of the sliding block 301, the sliding seat 30 and the mounting bracket 12 is ensured by the cooperation of the position sensors and the control panel 70, thereby ensuring the precision of the processing.

[0055] The implementation principle of this application embodiment is as follows: When in use, the experimenter places several test tubes containing water samples to be treated into the water sample placement area 2, and then starts the operation through the control panel 70.

[0056] First, through the cooperation of the first gripper 502 and the second drive assembly, the connecting seat 14 equipped with the detection mechanism 9 is moved away from the receiving seat. Then, through the cooperation of the sliding block 301 and the sliding seat 30, the detection mechanism 9 is moved in the horizontal direction, thereby completing the detection and judgment of the water sample in the water sample placement area 2. The setting positions of the oily water sample and the milky water sample are transmitted to the control panel 70 through an electrical signal. After the detection is completed and the detection mechanism 9 is moved to the corresponding position on the receiving seat again, the detection mechanism 9 can be put back on the receiving seat.

[0057] Secondly, the first gripper 502 is connected to the connecting seat 14 equipped with the reagent aspiration mechanism 10, thereby bringing the reagent aspiration mechanism 10 away from the receiving seat. When the reagent aspiration mechanism 10 moves directly above the clean pipette storage box 3, the entire mounting frame 12 is lowered, causing the clean pipette 90 to be nested on the outlet 1013 of the syringe 1011. Then, the mounting frame 12 moves upward to complete the connection between the clean pipette 90 and the reagent aspiration mechanism 10. Subsequently, based on the type of the first water sample in the water sample placement area 2 detected by the control panel 70 (assuming it is an emulsion-containing water sample), the reagent aspiration mechanism 10 is controlled to move to the storage location of the emulsion reagent kit 4. Through the lifting and lowering of the mounting frame 12 in conjunction with the reagent aspiration mechanism 10, the emulsion reagent is drawn into the pipette. Thus, with the cooperation of the mounting frame 12, the sliding seat 30, and the sliding block 301, the contents of the pipette are drawn into the emulsion reagent. The stored emulsion reagent is injected into the emulsion-containing water sample. After all the emulsion-containing water samples in the water sample placement area 2 have been injected with the emulsion reagent, the reagent aspiration mechanism 10 can be moved above the waste pipette recycling box 7. The used pipette is then retracted from the reagent aspiration mechanism 10 by the pipette retraction assembly 20 and falls into the waste pipette recycling box 7 for recycling. After that, the reagent aspiration mechanism 10 is moved back to the clean pipette storage box 3 and a clean pipette 90 is reconnected. It is then moved to the water-oil reagent kit 5 to draw the water-oil reagent into the pipette. The water-oil reagent is then injected into all the oil-containing water samples in the water sample placement area 2 until all the oil-containing water samples have been injected with the reagent. Then, the reagent aspiration mechanism 10 can be moved back to the waste pipette recycling box 7 by the reagent aspiration assembly 20.

[0058] Then, after the water sample in the water sample placement area 2 has been stationary for 15-20 minutes, the reagent aspiration mechanism 10 is reconnected to a clean pipette 90 via the control panel 70. Then, the waste liquid generated in the emulsion water sample containing the water-oil reagent is extracted and injected into the waste liquid recycling box 6. After all the waste liquid in the emulsion water sample has been extracted, the reagent aspiration mechanism 10 is moved above the waste pipette recycling box 7, and the used pipette is withdrawn from the reagent aspiration mechanism 10 via the pipette retraction assembly 20 and falls into the waste pipette recycling box 7 for recycling. Then, the reagent aspiration mechanism 10 is moved back to the clean pipette storage box 3 and a clean pipette 90 is reconnected. Then, the waste liquid generated in the oil water sample containing the water-oil reagent is extracted and discharged into the waste liquid recycling box 6. After all the waste liquid in the oil water sample has been extracted, the used pipette can be withdrawn back to the waste pipette recycling box 7 via the pipette retraction assembly 20. Then, the reagent aspiration mechanism 10 is placed back on the receiving seat.

[0059] Finally, the water sample in the water sample placement area 2 is moved to the centrifuge 8 by the water sample moving mechanism 60 for centrifugation. During the operation of the water sample moving mechanism 60, the cover 82 of the centrifuge 8 is automatically opened by the control panel 70 to facilitate the placement of the water sample. The cover 82 is automatically closed when the centrifuge 8 is running to ensure the normal centrifugation process of the centrifuge 8. After all the water samples have been centrifuged, the experimenters can take out the water samples, thus completing the pretreatment process of the water samples.
