Description

Technical Field

[0001] The present application relates to the technical field of polymerization inhibitor detection, and in particular to a sampling device and a method for using the same in a polymerization inhibitor production process. Background Art

[0002] Molecular distillation is a key step in the production of polymerization inhibitors. After molecular distillation, the inhibitors are stored in specialized tanks. Regular sampling and testing of the inhibitors in these tanks is essential to ensure product quality meets standards.

[0003] Currently, most inhibitor sampling equipment relies on manual operation, which has significant limitations and is inconvenient. It's difficult to accurately sample at varying depths within the tank, depending on actual needs. In actual production, inhibitors at varying depths may exhibit varying composition and properties due to factors such as temperature and pressure. Manual sampling also makes it difficult to precisely control the sampling depth, resulting in samples that fail to fully and accurately reflect the overall quality of the inhibitor within the tank, impacting the accuracy and reliability of product quality testing.

[0004] Furthermore, during manual sampling, sticky inhibitors can be carried out of the tank as the sampling equipment moves in and out of the tank. This escaped inhibitor not only wastes material but, more importantly, pollutes the air. Some inhibitors may contain harmful chemicals, posing a health risk to operators.

[0005] In view of the above problems, a sampling device and a method for using the same in the production process of polymerization inhibitors are now designed. Summary of the Invention

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] The embodiments of the present application provide a sampling device and a method for using the same in the production process of an inhibitor, which can solve the problem that most inhibitor sampling equipment in the related art relies on manual operation, making it inconvenient to sample samples at different depths in the sampling tank according to actual needs, and that some inhibitors will escape into the air during the sampling process.

[0026] See also Figure 1-Figure 3 , a sampling device for a polymerization inhibitor production process comprises: Workbench 1; storage tank 2, sampling unit 3 and storage unit 4 arranged relatively on the workbench 1; blowing mechanism 5; dust collection mechanism 6, the top of the storage tank 2 has a feed port 21, and the storage tank 2 is provided with an agitator 7; the sampling unit 3 includes a rotating table 31 arranged on the workbench 1, a driving member 32 arranged on the rotating table 31, a support frame 33 connected to the driving member 32, a sampling tank 34 connected to the support frame 33, and a valve 35 is provided at the bottom of the sampling tank 34, the rotating table 31 is used to control the rotation of the driving member 32, and the driving member 32 is used to control the lifting of the sampling tank 34 into the interior of the storage tank 2 Sampling; the storage unit 4 includes a rotating part 41 arranged on the workbench 1, a discharge table 42 connected to the rotating part 41, and a plurality of storage tanks 43 arranged on the discharge table 42, and the rotating part 41 is used to drive the discharge table 42 to rotate; the blowing mechanism 5 is arranged on the support frame 33 and is used to blow out the sample inside the sampling tank 34; the dust suction mechanism 6 includes an intake ring 61 arranged outside the sampling tank 34, a lifting part 62 arranged on the support frame 33, and a recovery unit 63 connected to the intake ring 61, the lifting part 62 is used to control the lifting and lowering of the intake ring 61, and the intake ring 61 is used to recover the sample contaminated on the surface of the sampling tank 34.

[0027] In actual operation, the rotating platform 31 starts to work, so that the support frame 33 connected to the driving member 32 and the sampling tank 34 connected to the support frame 33 rotate to a suitable position directly above the feed port 21 of the storage tank 2.

[0028] The driving member 32 is started, and the control support frame 33 drives the sampling tank 34 to descend, and the sampling tank 34 enters the interior of the storage tank 2. When the sampling tank 34 descends to a predetermined depth, the valve 35 at the bottom of the sampling tank 34 is opened, and the inhibitor sample enters the cavity at the bottom of the sampling tank 34.

[0029] After the sampling tank 34 is fully loaded with the sample, the valve 35 is closed, and the driving member 32 is started again, driving the support frame 33 to make the sampling tank 34 rise and leave the storage tank 2.

[0030] The lifting member 62 starts working, controlling the suction ring 61 to move back and forth along the length direction of the sampling tank 34. The suction ring 61 sucks the sample contaminated on the surface of the sampling tank 34 into the recovery unit 63. After cleaning is completed, the fan 2 is turned off and the suction ring 61 rises and resets.

[0031] Subsequently, the rotating member 41 drives the unloading platform 42 to rotate, rotating the storage tank 43 on the unloading platform 42 to a position corresponding to the sampling tank 34, ready to receive the sample. After that, the valve 35 at the bottom of the sampling tank 34 is opened, and the sample flows out of the sampling tank 34. The blowing mechanism 5 is activated to completely blow out the remaining sample, ensuring that the sample enters the storage tank 43. At the same time, the dust collection mechanism 6 works again to absorb the scattered and floating sample.

[0032] Repeat the above steps to sample samples at different depths. The rotating member 41 drives the discharge table 42 to rotate, and the samples in the sampling tank 34 are sent to different storage tanks 43.

[0033] The operator takes out the storage tank 43 from the discharge platform 42 using a clamp so as to carry out subsequent operations such as sample testing.

[0034] Through the cooperation of the rotating table 31, the driving part 32, the rotating part 41, the discharge table 42 and the storage tank 43, the position and depth of the sampling tank 34 can be accurately controlled, and the inhibitor at different depths in the storage tank 2 can be sampled to meet diverse testing needs, thereby more comprehensively and accurately understanding the overall quality of the inhibitor in the storage tank.

[0035] The sample in the sampling tank 34 can be blown out by the blowing mechanism 5 to avoid residue and improve the sampling effect.

[0036] The entire sampling process has achieved a high degree of automation, reducing manual intervention, lowering the errors and risks brought by manual sampling, improving sampling efficiency and operation accuracy, and also reducing the workload of operators.

[0037] After sampling from the sampling tank 34 and during the sample placement and blowing process, the dust collection mechanism 6 effectively absorbs the sample contaminated on the surface of the sampling tank 34 and the sample that has escaped and floated, preventing the polymerization inhibitor from leaking into the air, thus avoiding adverse effects on the air quality in the production workshop and protecting the health of the operators. Furthermore, the dust collection mechanism 6 recycles the escaped sample, reducing material waste and helping to control production costs.

[0038] like Figure 1 and Figure 10 As shown, it should be noted that the agitator 7 in this embodiment includes a driving motor and a reducer arranged above the storage tank 2, a stirring shaft arranged inside the storage tank 2, and a plurality of flaps arranged on the stirring shaft. The plurality of flaps separate the samples in the storage tank 2 into multiple areas, and the output shaft of the driving motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the rotating shaft.

[0039] In actual use, the drive motor starts, and its output shaft transmits power to the reducer. After the reducer adjusts the speed of the power, the output shaft drives the agitator shaft to rotate. The rotation of the agitator shaft drives the multiple flaps attached to it to move. As the flaps move, they separate the polymerization inhibitor inside the storage tank 2 into multiple relatively independent areas. The polymerization inhibitor in each area has a certain degree of relative independence due to the isolation of the flaps.

[0040] The movement of the flap ensures that inhibitors from different locations have the opportunity to enter the sampling tank. Since the inhibitors are separated into multiple zones, after sampling at different depths in the same zone is completed, the flap is pushed to move the sampling tank 34, allowing it to collect inhibitor samples from different zones, thereby completing multiple sampling operations at different depths.

[0041] like Figure 1 and Figure 9 As shown, a cover plate is hinged on the feed port 21 in this embodiment, and a groove provided on the cover plate is engaged with a fastening rod hinged on the side of the feed port 21 to fix the cover plate.

[0042] When the feeding operation is not being performed, the cover is in a closed state, covering the top of the feeding port 21 to prevent the polymerization inhibitor in the storage tank 2 from leaking and foreign matter from entering the tank.

[0043] The cover plate is provided with a groove, and a corresponding fastening rod is hingedly provided on the feed port 21. At this time, the top end of the fastening rod is clamped in the corresponding groove to limit and fix the cover plate.

[0044] like Figure 2 and Figure 3 As shown, the rotating table 31 in this embodiment includes a fixed frame 311 arranged on the workbench 1, a disc 312 is rotatably arranged on the fixed frame 311, a driving motor and a reducer are arranged at the bottom of the workbench 1, the output shaft of the driving motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the bottom of the disc 312.

[0045] When sampling is required, the drive motor is started, and the output shaft of the drive motor begins to rotate, transmitting power to the input shaft of the reducer. The reducer adjusts the speed of the power output by the drive motor, reduces the speed and increases the torque, and then transmits the processed power to the bottom of the disc 312 through its output shaft. Driven by the output shaft of the reducer, the disc 312 begins to rotate on the fixed frame 311.

[0046] As the disc 312 rotates, the driving member 32 mounted on the disc 312 also rotates. Since the driving member 32 is connected to the support frame 33, which in turn is connected to the sampling tank 34, the entire sampling unit 3 moves with the rotation of the disc 312. By precisely controlling the rotation angle and timing of the driving motor, the sampling tank 34 can be accurately moved to directly above the feed port 21 of the storage tank 2 or to another desired position.

[0047] When the sampling tank 34 reaches the designated position, the driving motor stops working. At this time, the disc 312 stops rotating, and the sampling unit 3 remains at the current position for subsequent sampling operations.

[0048] like Figure 2 and Figure 4 As shown, it should be noted that in this embodiment, the driving member 32 includes a fixing seat 321 and an electric slide rail 322 that are connected to each other. The fixing seat 321 is connected to the fixing frame 311, and the electric slide rail 322 is vertically arranged.

[0049] After the rotating table 31 rotates the sampling tank 34 to the appropriate position directly above the feed port 21 of the storage tank 2, the electric slide rail 322 is started, and the driving mechanism inside it drives the slider to move downward in the vertical direction. Since the support frame 33 is connected to the slider of the electric slide rail 322, as the slider descends, the support frame 33 and the sampling tank 34 also descend, and the sampling tank 34 gradually enters the interior of the storage tank 2.

[0050] When the sampling tank 34 descends to a predetermined depth, the valve 35 at the bottom of the sampling tank 34 is opened at the depth, and the electric slide rail 322 drives the sampling tank 34 to continue descending, so that the polymerization inhibitor enters the sampling tank 34 .

[0051] After sampling is completed, the electric slide 322 is started again, driving the slider to move upward in the vertical direction. The support frame 33 and the sampling tank 34 rise under the drive of the slider, leave the storage tank 2, return to the initial height position, and wait for the next sampling operation.

[0052] The electric slide rail 322 can accurately control the lifting speed and position of the slider, thereby achieving precise control of the lifting of the sampling tank 34.

[0053] An electric push rod is an electric actuator that converts electrical energy into mechanical energy to achieve linear motion. After the motor is decelerated by gears or a worm gear, it drives a pair of lead screw nuts to convert the motor's rotational motion into linear motion. The push rod action is completed by using the forward and reverse rotation of the motor. This is existing technology and will not be described in detail here.

[0054] like Figure 2 and Figure 4As shown, in one embodiment, the support frame 33 includes a plurality of fixed rods 331 connected to the slider of the electric slide rail 322, and a mounting cylinder 332 is provided at the other end of the plurality of fixed rods 331; the blowing mechanism 5 is provided on the side of the mounting cylinder 332, and the sampling tank 34 is provided at the bottom of the mounting cylinder 332.

[0055] Multiple fixing rods 331 are connected to the slider of the electric slide 322 at one end and to the mounting cylinder 332 at the other end, forming the overall structure of the support frame 33. This structure can withstand the weight of the sampling tank 34 and the blowing mechanism 5, as well as any external forces generated during the lifting process, ensuring the stability of the sampling tank 34 during the sampling process.

[0056] The support frame 33 is installed on the electric slide rail 322 through a slider, the sampling tank 34 is installed at the bottom of the installation cylinder 332, and the blowing mechanism 5 is arranged on the side of the installation cylinder 332.

[0057] like Figure 4 and Figure 7 As shown, specifically, the sampling tank 34 in this embodiment includes an insert rod 341 and a tank body 342 that are connected to each other, the insert rod 341 is connected to the mounting cylinder 332, and a cavity for accommodating the sample is opened at the bottom of the tank body 342; the valve 35 includes a disc 351 that is rotatably arranged in the cavity at the bottom of the tank body 342, and a driving motor 352 that is arranged on the side of the tank body 342, the driving motor 352 is connected to the disc 351, and is used to drive the disc 351 to rotate, and the disc 351 is adapted to the cavity of the tank body 342.

[0058] The rod 341 of the sampling tank 34 is connected to the mounting tube 332 of the support frame 33, securing the sampling tank 34 to the support frame 33 and placing it in a standby state. At this point, the valve 35 at the bottom of the tank body 342 is closed, and the disc 351 completely seals the cavity at the bottom of the tank body 342, preventing external substances from entering or internal substances from leaking.

[0059] During the sampling process, when the sampling tank 34 reaches the predetermined sampling depth, the drive motor 352 on the side of the tank body 342 is started, and the output shaft of the drive motor 352 rotates, driving the disc 351 connected thereto to rotate in the cavity at the bottom of the tank body 342 .

[0060] As the disc 351 rotates, the cavity communicates with the interior of the external storage tank 2. At this time, as the sampling tank 34 continues to descend, the inhibitor in the storage tank 2 enters the cavity at the bottom of the tank body 342, completing the sampling operation.

[0061] After the sampling is completed, the driving motor 352 is started again to drive the disc 351 to rotate in the opposite direction, so that the disc 351 re-seals the cavity at the bottom of the tank body 342 to prevent the sample from leaking during the ascending process of the sampling tank 34.

[0062] The driving motor 352 can be remotely controlled. The operator only needs to enter the corresponding instructions on the control panel to open and close the valve 35. There is no need to manually operate the complex mechanical structure, which improves the convenience and efficiency of operation.

[0063] like Figure 3 and Figure 5 As shown, in one embodiment, the rotating member 41 includes a turntable 411 rotatably arranged on the workbench 1, an annular enclosure 412 is provided on the turntable 411, and a second drive motor and a second reducer are provided at the bottom of the workbench 1, the output shaft of the second drive motor is connected to the input shaft of the second reducer, and the output shaft of the second reducer is connected to the turntable 411; The discharge platform 42 is plugged into the turntable 411 and is located inside the annular enclosure 412. The discharge platform 42 is provided with an annular storage groove 421. The storage tank 43 is arranged in the storage groove 421. The discharge platform 42 is provided with a protective cylinder 423 located outside the storage groove 421. The protective cylinder 423 is used to prevent the sample from floating outward when the sampling tank sends the sample into the storage tank 43.

[0064] The top of the storage tank 43 is open, and two protrusions are provided on the sides opposite to each other, so that the operator can easily clamp the storage tank 43 with a clamp through the protrusions.

[0065] An annular enclosure 412 is fixed to the turntable 411, forming a certain storage space. The unloading platform 42 is inserted into the storage space and has multiple annular storage slots 421 arranged on it. The operator uses a clamp to grasp the two opposing protrusions on the sides of the storage tank 43 and place the storage tank 43 in each storage slot 421 of the unloading platform 42. The open top of the storage tank 43 facilitates the subsequent reception of samples from the sampling tank.

[0066] When it is necessary to replace or position a different storage tank 43 to receive the sample, the drive motor 2 is started, and its output shaft drives the input shaft of the reducer 2 to rotate. After the reducer 2 reduces the speed and increases the torque, its output shaft drives the turntable 411 to rotate. The rotation of the turntable 411 drives the unloading table 42 and the storage tank 43 thereon to rotate together. The control system controls the rotation angle and time of the drive motor 2 so that the designated storage tank 43 rotates to the sample delivery position corresponding to the sampling tank 34.

[0067] After the sample of one storage tank 43 is delivered, the drive motor 2 can be started again as needed to rotate the turntable 411 and the discharge table 42 to rotate the next empty storage tank 43 to the sample delivery position, and repeat the above sampling and sample delivery process until all storage tanks 43 have completed sample reception.

[0068] Multiple storage tanks 421 are distributed in a ring on the discharge table 42, making full use of the space. Multiple storage tanks 43 can be placed on the limited area of ​​the workbench 1 to meet the needs of multiple sampling and storage, making the entire sampling and storage system more compact and efficient.

[0069] like Figure 4 As shown, in a preferred embodiment, the blowing mechanism 5 includes a fan 51 arranged on a support frame 33, and an air pipe 52 is provided at the air outlet of the fan 51. The other end of the air pipe 52 is connected to the internal cavity of the tank body 342, and a filter is provided at the air inlet of the fan 51.

[0070] The air inlet of the fan 51 is equipped with a filter for filtering the air entering the fan to prevent dust, impurities, etc. from entering the fan and affecting the performance and service life of the fan.

[0071] During the sampling process, fan 51 receives the blow command and starts operating. The fan blades rotate, creating a negative pressure at the air inlet, forcing the outside air to pass through the filter at the air inlet before entering the fan. The air is compressed and accelerated within the fan, forming a high-pressure airflow. This airflow is then discharged from the air outlet of fan 51 and into air pipe 52. The high-pressure airflow flows rapidly along air pipe 52 and is ultimately delivered to the interior cavity of tank 342.

[0072] After the high-pressure airflow enters the internal cavity of the tank body 342, it blows out the sample in the sampling tank 34 and the sample remaining in the tank body 342, ensuring that the sample in the sampling tank 34 can be discharged smoothly and ensuring the accuracy of the next sampling.

[0073] When the sample delivery operation is completed, the control system will send a stop command to the fan 51, the fan 51 stops running, the air flow stops delivering, and the blowing mechanism 5 returns to the initial state, waiting for the next blowing command.

[0074] By blowing and cleaning the inside of the sampling tank 34, the residual sample in the tank body 342 can be removed, avoiding sample residue and preventing the sample residue from contaminating the sample of the next sampling, thereby improving the purity and accuracy of the sampled sample and providing reliable data support for subsequent analysis and detection.

[0075] like Figure 4 and Figure 6 As shown, in one embodiment, the suction ring 61 includes a circular ring 611 and a mounting seat 612 that are connected to each other, and the circular ring 611 and the mounting seat 612 are internally provided with air cavities 613 that are connected to each other. The circular ring 611 is sleeved on the outside of the tank body 342; the inner side of the circular ring 611 is provided with multiple dust suction holes 614 that are connected to the air cavity 613.

[0076] The air intake ring 61 is composed of a circular ring 611 and a mounting seat 612 that are connected to each other. The mounting seat 612 is used to be tightly connected to the circular ring 611 to ensure the stability of the entire air intake ring 61 structure; on the other hand, it provides an installation location for other components, making it convenient to connect and integrate with other equipment.

[0077] The ring 611 and the mounting base 612 are interconnected by an air cavity 613. This cavity 613 is the part of the suction ring 61 that performs the gas recovery function, providing a closed passage for the flow of gas. Through this cavity 613, the material sucked in through the dust suction hole 614 inside the ring 611 can be smoothly transferred to the recovery unit.

[0078] The distribution and number of the dust suction holes 614 are generally designed based on actual recycling needs and the size of the tank 342. Multiple dust suction holes 614 can increase the suction area of ​​gas and impurities and improve recycling efficiency.

[0079] When the recovery unit 63 is started, a negative pressure environment is formed in the air cavity 613, and the ring 611 is mounted on the outside of the tank body 342. The residual samples around the tank body 342 are sucked into the air cavity 613 through the multiple dust suction holes 614 on the inside of the ring 611 under the action of the negative pressure of the air cavity 613.

[0080] like Figure 4 As shown, as a preferred embodiment, the lifting member 62 includes an electric push rod arranged on the support frame 33, and the bottom end of the piston rod of the electric push rod is connected to the mounting seat 612, which is used to control the movement of the suction ring 61 along the length of the insertion rod 341 and the tank body 342.

[0081] When the position of the air intake ring 61 needs to be adjusted, the control system sends a command to the electric push rod. When the piston rod of the electric push rod is extended, it pushes the mounting seat 612 downward, thereby driving the air intake ring 61 to move downward along the periphery of the insertion rod 341 and the tank body 342; when the piston rod is retracted, it drives the air intake ring 61 to move upward.

[0082] By controlling the position of the suction ring 61, it can be better matched with the tank body 342 and other components of the sampling tank 34. During the sampling process or when recovering samples, it can accurately cover or approach the area that needs to be processed, thereby improving the efficiency and accuracy of sample recovery.

[0083] like Figure 8As shown, further, the recovery unit 63 in this embodiment includes a recovery tank 631 and a second fan 632 arranged at the bottom of the workbench 1, and a sealing cover 633 is clamped above the recovery tank 631. Two connecting nozzles 1 634 are provided on the sealing cover 633, and the connecting nozzle 1 634 is communicated with the recovery tank 631. A connecting nozzle 2 635 is provided on the mounting base 612, and the connecting nozzle 2 635 is communicated with the air cavity 613. The connecting nozzle 2 635 is connected to one of the connecting nozzles 1 634 through a hose 636, and a filter located inside the recovery tank 631 is provided at the bottom of the other connecting nozzle 1 634, and the other connecting nozzle 1 634 is communicated with the air inlet of the second fan 632.

[0084] The first connection nozzle 634 is connected to the recovery tank 631, and the second connection nozzle 635 is provided on the mounting base 612 and is connected to the air cavity 613. The second connection nozzle 635 is connected to one of the first connection nozzles 634 via a hose 636, thereby achieving communication between the air cavity 613 and the recovery tank 631.

[0085] In actual operation, after the fan 2 632 is started, negative pressure is generated inside the recovery tank 631. Since the connecting nozzle 2 635 is connected to one of the connecting nozzles 1 634 through the hose 636, and the connecting nozzle 2 635 is connected to the air cavity 613, the residual sample in the air cavity 613 will be sucked into the hose 636 under the action of the negative pressure, and then enter the recovery tank 631.

[0086] Another connecting nozzle 1 634 is connected to the air inlet of fan 2 632 and has a filter at its bottom. As the material enters the recovery tank 631, the filter filters the material, blocking the sample outside the filter. The gas can pass through the filter and enter the air inlet of fan 2 632, and then exit the system through the air outlet of fan 2 632.

[0087] The negative pressure generated by the second blower 632 can quickly and effectively suck the substances in the air cavity 613 into the recovery tank 631, thereby improving the efficiency of sample recovery.

[0088] In this embodiment, a tool box is provided on the workbench 1 to place accessories.

[0089] In a preferred embodiment, the bottom of the workbench 1 in this embodiment is provided with equally spaced moving wheels, which can be used to power the device through cables and facilitate its movement.

[0090] Furthermore, a battery is provided at the bottom of the workbench, and the battery is used to power the rotating table 31, the driving member 32, the sampling tank 34, the valve 35, the rotating member 41, and the recovery unit 63, thereby improving the mobility efficiency and convenience.

[0091] A sampling method in a polymerization inhibitor production process comprises the following steps: S1: Check the sampling device to ensure that all parts are firmly connected, without looseness or damage, and that all moving parts are functioning normally. Move the device to a suitable location in the storage tank.

[0092] S2: Sampling operation, the disc is driven to rotate by the turntable, the driving part is turned to the appropriate position, the sampling tank is aligned with the feeding port of the storage tank, and the sampling tank is driven by the driving part to descend into the storage tank. After reaching a certain depth, the valve is opened and the sampling tank continues to descend to allow the sample to enter the tank cavity. After being fully loaded, the descent is stopped and the valve is closed. The driving part is started again, and the support frame drives the sampling tank to rise and leave the storage tank.

[0093] S3: Vacuuming operation, the suction ring is moved back and forth along the length direction of the sampling tank through the lifting part, and the suction ring sucks the sample on the surface of the sampling tank into the recovery tank through the second fan of the recovery unit. After cleaning, the second fan is turned off and the suction ring is reset.

[0094] S4: Sample transfer, the rotating table moves the sampling tank to the top of the discharge table, and the storage tank on the discharge table is replaced by the rotating part to perform multiple groups of sampling.

[0095] S5: Sample blowing, open the sampling tank valve, the sample flows out, and the air is blown into the tank cavity through the blowing mechanism, blowing out the residual sample into the storage tank. At the same time, the dust collection mechanism works again to absorb the scattered sample.

[0096] S6: Take out the sample and remove the storage tank from the storage tank of the discharge table for subsequent sample testing and other operations.

[0097] Before sampling, the operator needs to check the various components of the sampling device to ensure that they are firmly connected, not loose or damaged, and that all moving parts can operate normally.

[0098] The disc 312 is driven to rotate by the rotating table 31, so that the driving member 32 is turned to the appropriate position, and the sampling tank 34 is aligned with the feed port 21 of the storage tank 2. The driving member 32 is started, driving the sampling tank 34 to descend into the interior of the storage tank 2. When the sampling tank 34 descends to a certain depth, the valve 35 is opened and continues to descend so that the sample enters the cavity of the tank body 342.

[0099] When the sampling tank 34 is fully loaded, it stops descending and closes the valve 35. The driving member 32 is started again, and the support frame 33 drives the sampling tank 34 to rise and leave the storage tank 2.

[0100] The suction ring 61 is reciprocated along the length of the sampling tank 34 by means of a lifting member 62, activating blower 2 632 of the recovery unit 63. The suction ring 61 draws the sample contaminated on the surface of the sampling tank 34 into the air cavity 613 through the dust suction hole 614, and then into the recovery tank 631 through the hose 636. Once cleaning is complete, blower 2 632 is turned off, and the suction ring 61 is returned to its original position.

[0101] The rotating platform 31 moves the sampling tank 34 to above the discharge platform 42, and the rotating member 41 drives the discharge platform 42 to rotate, so that the storage tank 43 on the discharge platform 42 can be replaced, so as to perform multiple groups of sampling.

[0102] The valve 35 of the sampling tank 34 is opened, and the sample flows out. The blower 51 of the air blowing mechanism 5 is activated, blowing air into the cavity of the tank body 342 through the air pipe 52, blowing out the residual sample into the storage tank 43. At the same time, the dust collection mechanism 6 starts working again, absorbing the scattered sample to prevent it from polluting the environment.

[0103] The storage tank 43 is taken out from the storage slot 421 of the discharge platform 42 for subsequent operations such as sample testing.
