Description

Technical Field

[0001] The invention relates to the technical field of water quality monitoring, in particular to a swing type extractor and a turnover extraction method. Background Art

[0002] The concentration of petroleum in wastewater from oil extraction, refining, transportation, and storage needs to be monitored. It can only be discharged into the environment after reaching the national limit. In addition, in order to promptly detect and prevent oil leakage caused by aging equipment, pipeline damage, etc., which causes water pollution, the oil content in cooling and circulating water must also be tested regularly every day during the production process.

[0003] At present, online monitoring devices are generally used to replace traditional manual timed sampling monitoring to avoid the impact of toxic petroleum components and toxic reagents on the bodies of operators in manual contact. In commonly used online monitoring devices, stirring extraction or horizontal oscillation extraction is often used for extraction. However, both methods have the disadvantage of insufficient contact between the water sample and the extract, resulting in a low extraction rate. Among them, in the stirring extraction method, the stirring device mostly rotates in one direction. After the water sample and the extract are rotated, the two rotate at the same speed. The water sample and the extract located on the upper and lower layers do not collide with each other sufficiently, resulting in a poor extraction of oil from the water, and the extraction efficiency is very low. In the horizontal oscillation extraction, there is also a problem that the water sample and the extract are not in sufficient contact, resulting in a low extraction rate.

[0004] Therefore, there is an urgent need for a swinging extractor and a flipping extraction method that can enable the water sample and the extract to be flipped up and down multiple times for full contact, thereby improving the extraction rate. Summary of the invention

[0005] The object of the present invention is to overcome the above technical defects and provide a swinging extractor and a flipping extraction method, which can make the water sample and the extract liquid flip up and down multiple times to fully contact each other, thereby improving the extraction rate.

[0006] The technical solution to achieve the above purpose is:

[0007] The present invention provides a swing type extractor, comprising:

[0008] An extraction container, the extraction container is mounted on a swing member through a first component, and the extraction container is sealed and connected to an external flow path;

[0009] A driving device is connected to the swing member through a second component, and the driving device controls the swing member to swing back and forth within a flat angle range, thereby driving the extraction container to turn upside down.

[0010] A further improvement of the swing type extractor of the present invention is that the first component comprises an upper cover plate, a base and a protective cover, and the upper cover plate, the base and the protective cover are arranged around the periphery of the extraction container and fixed on the swing component.

[0011] A further improvement of the swing-type extractor of the present invention is that the second component includes a bracket, the bracket has a through hole along the Z-axis direction, a bearing seat is provided on the bracket, the axial hole of the bearing seat is aligned with the through hole, the driving device is arranged on the bracket, the swing member is connected to a rotating shaft, the rotating shaft and the output shaft of the driving device are passed through the through hole and the axial hole of the bearing seat and are connected through a coupling.

[0012] A further improvement of the swing-type extractor of the present invention is that a pair of first limit blocks are provided on the second component along the X-axis direction, and a pair of the first limit blocks are relatively arranged on both sides of the second component, one of the first limit blocks is provided with an optical coupler for communication connection with an external control system, and a gap is provided between the light-emitting part and the light-receiving part of the optical coupler, and a second limit block is provided on the swing component in alignment with the optical coupler, and the second limit block has a protrusion for blocking the light-emitting part and the light-receiving part, and the protrusion and the first limit block are staggered in the Y-axis direction.

[0013] A further improvement of the swing type extractor of the present invention is that the swing component includes a counterweight portion, and the counterweight portion and the extraction container are located on both sides of the rotating shaft relative to each other.

[0014] The present invention also provides a swing extraction method, comprising the following steps:

[0015] Step 1, taking a sample into the extraction container, and introducing an extraction reagent into the extraction container;

[0016] Step 2, starting the driving device to control the extraction container to swing back and forth within a flat angle range, driving the extraction container to flip up and down to achieve full extraction;

[0017] Step 3, taking out the extracted mixed solution for the next step of testing.

[0018] A further improvement of the extraction method of the present invention is that the swing type extractor further comprises the first limit block, the optical coupler and the second limit block;

[0019] The extraction method also includes the steps of:

[0020] After step 2, the method further includes detecting whether the optical coupler is connected through an external control system. If connected, the driving device is continuously started to drive the swing member to rotate until the protrusion of the second limit block blocks the light-emitting part and the light-receiving part of the optical coupler to disconnect the optical coupler and reset the extraction container.

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0037] Embodiment 1

[0038] See also Figures 1 to 5 The present invention provides a swing type extractor, comprising:

[0039] An extraction container 10, the extraction container 10 is mounted on a swing member 30 through a first assembly 20, and the extraction container 10 is sealed and connected to an external flow path;

[0040] The driving device 40 is connected to the swing member 30 through the second component 50. The driving device 40 controls the swing member 30 to swing back and forth within a flat angle range, thereby driving the extraction container 10 to turn upside down.

[0041] In the first embodiment of the present invention, the extraction container 10 is fixed to the swinging member 30 by the first component 20 to ensure that it will not fall off during the swinging process due to looseness or other reasons. It is suitable for a smaller amount of extraction liquid. The extraction container 10 can be a container with a smaller capacity. In this embodiment, an extraction cup is used. The extraction cup has a sealed cup cover. The cup cover has a liquid opening. There are multiple liquid openings, which can be used as the inlet and outlet of the water sample and the inlet and outlet of the extraction reagent respectively. When the extraction cup is connected to the external flow path, it is necessary to keep it sealed to prevent leakage by adding a seal.

[0042] Preferably, in this embodiment, please refer to Figure 3 The first component 20 includes an upper cover plate 21 , a base 22 and a protective cover 23 . The upper cover plate 21 , the base 22 and the protective cover 23 are arranged around the periphery of the extraction container 10 and fixed on the swing member 30 . Specifically, the upper cover pressing plate 21, the base 22 and the protective cover 23 enclose a accommodating space for the extraction cup in this embodiment, and the accommodating space is adapted to the outer contour of the extraction cup, preferably covering it. The upper cover pressing plate 21 and the base 22 cooperate to support the extraction cup and seal the cup cover. The upper cover pressing plate 21 opens a plurality of liquid passages corresponding to the extraction cup for introducing an external flow path. These liquid passages also need to be sealed. It should be noted that during the installation of the actual device, it is preferred that these sealed liquid passages are located on the same side of the extraction container 10, and when returned to the zero point, the opening of the extraction cup of the extraction container 20 is preferably facing upward to ensure that during the swinging process, the flow path is not entangled due to the problem of the swinging angle, which affects the continuous extraction. The protective cover 23 is made of steel material, which can protect the internal extraction cup.

[0043] In the first embodiment of the present invention, the driving device 40 adopts a stepper motor, the power of which is selected according to the rotation torque and the overall weight of the rotating shaft end, and is fixed to the designed position of the oil in water measuring device by means of fixing parts, etc. For example, a commonly used 57 stepper motor can be used, and the stepper motor is pulsed by a driver, and the driver is controlled by an external control system to set the size of the pulse. The pulse of the driver is used to control the rotation angle of the driving shaft of the stepper motor to control the swing member 30 to swing back and forth within the flat angle range (i.e., within 0 to 180°). It should be noted that, considering the extraction efficiency, the maximum swing angle is preferably between 150° and 180°, so that the liquid in the entire extraction container can be fully flipped up and down, thereby further improving the extraction rate.

[0044] In the first embodiment of the present invention, the swing member 30 is made of metal material, such as aluminum alloy, etc., which has a good service life and is light in weight. It can be suitable for frequent repeated swinging processes and can reduce the adaptation power of the drive device 40. The drive device 40 is connected to the swing member 30 through the second component 50. Preferably, the second component 50 includes a bracket 51, and the bracket 51 has a through hole along the Z-axis direction. The bracket 51 is provided with a bearing seat 52, and the shaft hole of the bearing seat 52 is aligned with the through hole. The drive device 40 is arranged on the bracket 51, and the swing member 30 is connected to a rotating shaft 53. The rotating shaft 53 and the output shaft of the drive device 40 are passed through the through hole and the shaft hole of the bearing seat 52 and are connected through a coupling 54. Please continue to refer to Figure 1In this embodiment, the second component 50 is similar to the material of the above-mentioned swing member 30, and is made of metal to increase strength and service life. The bracket 51 is in the shape of a sub-letter, and the interior is hollow. The bracket 51 is provided with a group of through holes in the Z-axis direction, and the bearing seat 52 is placed in the hollow opening. By setting the bearing seat 52 and connecting the output shaft and the swing member 30 through the coupling 54, the entire rotation transmission process of the driving device 40 can be smooth. The rotating shaft 53 is connected to the middle of the swing member 30 and fixed by welding or screws. Preferably, the swing member 30 includes a counterweight part 31, and the counterweight part 31 and the extraction container 10 are relatively located on both sides of the rotating shaft 53. Through this design, the rotation inertia of the counterweight part 31 and the extraction container 10 is transformed into each other as much as possible. During the swinging process, after reaching a certain angle, the counterweight part 31 can continue to drive the extraction container 10 to rotate to the designed angle. In the reciprocating process, it can play a role, which can reduce the demand for the output power of the driving device 40 and reduce the power selection of the motor in the driving device 40.

[0045] As a preferred implementation of the first embodiment of the present invention, please refer to Figure 2 Combined with Figures 4 to 5A pair of first limit blocks 60 are provided on the second component 50 along the X-axis direction, and the pair of first limit blocks 60 are relatively arranged on both sides of the second component 50, one of the first limit blocks 60 is provided with an optical coupler 70 for communication connection with an external control system, and a gap 73 is provided between the light-emitting portion 71 and the light-receiving portion 72 of the optical coupler 70, and a second limit block 80 is provided on the swing member 30 in alignment with the optical coupler 70, and the second limit block 80 has a protrusion 81 for blocking between the light-emitting portion 71 and the light-receiving portion 72, and the protrusion 81 is staggered with the first limit block 60 in the Y-axis direction. In the first embodiment, specifically, the first limit block 60 is a convex block protruding from both sides of the bracket 51. The convex block is integrally formed with the bracket 51, and the size of the convex block is designed according to needs. The shape of the protrusion 81 of the second limit block 80 is compatible with the shape of the gap 73 of the optical coupler 70. The optical coupler 70 is communicatively connected to the external control system. When the control system applies a power signal to the light-emitting part 71, the light-emitting part 71 emits light, and the light-receiving part 72 generates a photocurrent after receiving the light, and the photocurrent flows out from the light-receiving part 72, thereby realizing "electric-optical-electrical" control. In this embodiment, the optical coupler 70 cooperates with the second limit block 80 to play the following roles: on the one hand, the optical coupler 70 serves as the zero point of the entire swing member 30. When the swing member 30 is at the zero point, the protrusion 81 of the second limit block 80 located on the optical coupler 70 is blocked in the gap 73. At this time, the light of the light-emitting part is blocked, and the external control system feedbacks the disconnection signal of the optical coupler 70, and detects that the swing member 30 is at the zero point. On the other hand, during use, the optical coupler 70 serves as a means of reset detection. Similarly, if the optical coupler 70 is connected, the external control system feedbacks that the swing member 30 has not reset, and then continues to send signals to reset the swing member 30 until the optical coupler 70 is disconnected. In addition, the optical coupler 70 can also cooperate with the first limit block 60 and the second limit block 80 to limit together. The swing member 30 swings from the optical coupler 70 to the first limit block 60 on the other side. Since the protrusion 81 of the second limit block 80 and the first limit block are staggered in the Y-axis direction to form a blockage, the swing member 30 is limited to swing within a flat angle range.

[0050] Step S3, taking out the extracted mixed solution for the next step of detection.

[0051] In a preferred embodiment of the second embodiment of the present invention, the swing type extractor further comprises the first limit block 60, the optical coupler 70 and the second limit block 80 in the first embodiment;

[0052] The extraction method also comprises the steps of:
