Description

Technical Field

[0001] This application relates to the technical field of sampling devices, and more particularly, to a sampling device. Background Art

[0002] Sampling devices for chemical liquid samples are often used in chemical equipment. In existing equipment, during the sampling operation, a measuring instrument is usually directly placed at the lower end of a sampling hose to receive the sample liquid conveyed by the hose.

[0003] However, when using existing sampling devices to receive sample liquid, due to reasons such as height difference and flow rate, the sample liquid is extremely easy to splash, which can easily cause harm to the staff around the sampling device, resulting in low safety. Summary of the Utility Model

[0004] Based on the above deficiencies, this application provides a sampling device to improve the safety problem caused by sample liquid splashing during sampling in related technologies.

[0005] This application is implemented as follows:

The interior of the cabinet body has a receiving cavity, and an opening communicating with the receiving cavity is provided on one vertical side of the cabinet body; the infusion mechanism includes a vertically arranged sampling tube, and the sampling end of the sampling tube is located in the receiving cavity; the opening is for a container to penetrate into the receiving cavity and be placed on the bottom plate of the cabinet body to receive the sample liquid conveyed by the sampling tube; the anti-splash mechanism includes a turntable and a vertically arranged transparent baffle, the turntable is rotatably connected to the inner wall of the cabinet body, and the transparent baffle is connected to the turntable; the turntable can selectively drive the transparent baffle to rotate to the opening to separate the container and the sampling tube from the opening.

[0007] In the above implementation process, the sampling end of the sampling tube is extended into the receiving cavity inside the cabinet body, and an opening is provided on one vertical side of the cabinet body. The operator can place the container through the opening on the bottom plate inside the receiving cavity of the cabinet body to receive the sample liquid conveyed by the sampling tube. Since the sample liquid is likely to splash out of the container during the process of receiving the sample liquid, the sampling device provided in this application example also has an anti-splash component. When using the container to receive the sample liquid conveyed by the sampling tube, the transparent baffle can be rotated to the opening through the turntable to separate the container and the sampling tube from the opening, reducing the probability of the sample liquid splashing outside the opening, thereby improving the sampling safety.

[0008] In an alternative embodiment, along the vertical direction, the bottom end of the transparent baffle extends below the middle of the container; the bottom plate is provided with a liquid discharge hole.

[0009] In the above implementation process, the bottom end of the transparent baffle extends below the middle of the container, which can further reduce the probability of the sample liquid splashing out of the opening while ensuring the smoothness of the transparent baffle rotation. In addition, a drainage hole is provided on the bottom plate, and the sample liquid splashed from the container can be discharged from the drainage hole of the bottom plate.

[0010] In an optional embodiment, a partition is provided in the cabinet, the partition is fixed to the inner wall of the cabinet and is located above the bottom plate; the partition is provided with a first through hole, and the sampling end of the sampling tube passes through the first through hole and is located below the partition; the turntable is rotatably connected to the partition and is located below the partition, and the transparent baffle is located on the side of the turntable facing away from the partition.

[0011] In the above implementation process, a first through hole is set at the partition, and the sampling end of the sampling tube can be extended into the bottom of the partition through the first through hole, so that the turntable rotatably connected to the partition can drive the transparent baffle located under the partition to rotate to the opening to cover the container and the sampling tube during sampling.

[0012] In an optional embodiment, the partition is provided with an arc-shaped slideway, and a sliding column is provided on the upper side of the turntable. The sliding column extends into the arc-shaped slideway and can selectively slide along the arc-shaped slideway.

[0013] In the above implementation process, an arc-shaped slideway is arranged at the turntable, and a slide column extending into the arc-shaped slideway is arranged at the turntable. The cooperation between the slide column and the arc-shaped slideway can be used to limit the rotation angle of the turntable.

[0014] In an optional embodiment, the inner wall of the arc-shaped slideway has a thread arranged along the extending direction of the arc-shaped slideway, the slide post is a stud, and the turntable rotates along the thread as the stud rotates.

[0015] In the above implementation process, a thread is set in the arc-shaped slide along the extension direction of the slide, and the slide column is set as a stud. The stud can be rotated to slide along the thread in the arc-shaped slide in the extension direction of the slide, thereby driving the turntable to rotate, so that the transparent baffle is rotated to the opening to separate the container and the sampling tube from the opening.

[0016] In an optional embodiment, the top end of the stud passes through the arc-shaped slideway and is located above the partition, and a knob is provided at the top end of the stud.

[0017] In the above implementation process, a knob is set at the top of the stud extending above the partition, and the stud can be rotated by rotating the knob to move along the arc slide, thereby driving the turntable and the transparent baffle set at the turntable to rotate.

[0018] In an optional embodiment, a pick is protruding from a side of the transparent baffle away from the sampling tube.

[0019] In the above implementation process, a paddle is provided on the side of the transparent baffle away from the sampling tube, and the operator can rotate the transparent baffle by paddle.

[0020] In an optional embodiment, a mounting groove is provided on the side of the partition facing the bottom plate, and a round table with a smaller upper part and a larger lower part is protruding downward in the mounting groove; a second through hole matching the round table is provided on the turntable, the turntable is arranged in the mounting groove, and the hole wall of the second through hole is sleeved on the outside of the round table and rotatably engaged with the round table.

[0021] In the above implementation process, a mounting groove is provided on the bottom side of the partition, and the turntable can be placed in the mounting groove so that the turntable can rotate in the mounting groove. In addition, a round platform with a small top and a large bottom is protruding downward in the mounting groove, and a second through hole matching the round platform is provided at the turntable, and the turntable can be sleeved on the round platform through the second through hole. Since the outer diameter of the lower end of the round platform is larger than the inner diameter of the upper end of the second through hole, the round platform can prevent the turntable from falling downward.

[0022] In an optional embodiment, the turntable is a circular disc, and a first arc-shaped boss is radially protruding from the side surface of the circular disc; the cross-section of the mounting groove is circular, and a second arc-shaped boss is radially protruding from the side surface of the mounting groove toward the direction of the circular disc, so that the first arc-shaped boss can selectively abut against both ends of the second arc-shaped boss as the turntable rotates.

[0023] In the above implementation process, a second arc-shaped boss protruding inward is set on the side of the installation groove. When the turntable rotates in the installation groove, the first arc-shaped boss can selectively abut against both ends of the second arc-shaped boss, thereby limiting the rotation arc of the turntable in the installation groove.

[0024] In an optional embodiment, the infusion mechanism includes a valve, and the valve is arranged on the sampling tube.

[0025] In the above implementation process, a valve is provided at the sampling tube, and the valve can be used to control the opening or closing of the sampling tube, so that the sampling tube can be selectively used to transport the sample liquid to the container below.

[0036] Chemical sampling devices are commonly used in chemical equipment. In existing equipment, during the sampling operation, a measuring device is usually directly placed at the lower end of the sampling hose to receive the sample liquid transported by the hose. However, when using existing sampling equipment to receive the sample liquid, due to factors such as height difference and flow rate, the sample liquid is extremely likely to splash, which can easily cause harm to the staff around the sampling equipment, resulting in relatively low safety.

[0037] Therefore, this application provides a sampling device 1, which can, to a certain extent, improve the safety problem caused by the easy splashing of the sample liquid during sampling. To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0038] Please refer to Figure 1 , this application example provides a sampling device 1, including a cabinet 10, an infusion mechanism 20, and an anti-splash mechanism 30.

[0039] Among them, please combine Figure 1 and Figure 2 . The interior of the cabinet 10 has a receiving cavity 11. An opening 12 communicating with the receiving cavity 11 is provided on one vertical side of the cabinet 10. An operator can insert the container 2 into the receiving cavity 11 through the opening 12 and place it on the bottom plate 13.

[0040] Among them, please continue to combine Figure 1 and Figure 2 . The infusion mechanism 20 includes a vertically arranged sampling tube 21. The sampling end 211 of the sampling tube 21 is located in the receiving cavity 11. The sampling end 211 is located above the bottom plate 13 to facilitate using the container 2 to receive the sample liquid transported by the sampling tube 21.

[0041] Among them, please combine Figure 1 , Figure 2 and Figure 3 . The anti-splash mechanism 30 includes a turntable 31 and a vertically arranged transparent baffle 32. The turntable 31 is rotatably connected to the inner wall of the cabinet 10, and the transparent baffle 32 is connected to the turntable 31. The turntable 31 can selectively drive the transparent baffle 32 to rotate to the opening 12 to separate the container 2 and the sampling tube 21 from the opening 12.

[0042] When using the above sampling device 1 for sampling, the container 2 can be inserted into the receiving cavity 11 through the opening 12 and placed on the bottom plate 13, and the container 2 is located below the sampling end 211. Then, rotate the turntable 31 to make the transparent baffle 32 rotate to the opening 12 to separate the container 2 and the sampling tube 21 from the opening 12. Therefore, even if the sample liquid splashes when the sampling tube 21 transports the sample liquid into the container 2, the splashed sample liquid will be blocked by the transparent baffle 32 and basically cannot splash out from the opening 12, thereby improving the sampling safety.

[0043] The cabinet 10 , the infusion mechanism 20 and the anti-splash mechanism 30 in the sampling device 1 provided by the example of the present application are further described in detail below in conjunction with the accompanying drawings.

[0044] The cabinet 10 is used to carry the infusion mechanism 20 and the splash prevention mechanism 30, and the cabinet 10 has a receiving cavity 11 that can receive the container 2 to receive the sample liquid, and the inner wall of the receiving cavity 11 of the cabinet 10 can protect the sampling tube 21 and the container 2. In addition, in order to facilitate the placement of the container 2 into the receiving cavity 11 and the removal of the container 2 from the receiving cavity 11, an opening 12 is further provided on one side of the vertical direction of the cabinet 10. The opening 12 extends to the bottom plate 13.

[0045] Exemplarily, the cabinet 10 includes a rectangular bottom plate 13, and three vertical plates arranged on three sides of the rectangular bottom plate 13, the three vertical plates are connected in sequence, and a top plate is arranged on the top of the three vertical plates. The top plate, the vertical plates and the bottom plate 13 together form a receiving cavity 11, and the opening 12 is located on the side of the bottom plate 13 where the vertical plates are not arranged, so that the operator can place the container 2 on the bottom plate 13 through the opening 12.

[0046] When the container 2 is used to receive the sample liquid transported by the sampling tube 21, the sample liquid may splash. The splashed sample liquid may directly drip onto the bottom plate 13, or may splash onto the inner wall of the cabinet 10 or the transparent baffle 32, and then slide from the inner wall of the cabinet 10 or the transparent baffle 32 onto the bottom plate 13. Therefore, the sample liquid is easily accumulated on the bottom plate 13.

[0047] In order to reduce the risk of the sample liquid on the bottom plate 13 flowing out of the cabinet 10 from the opening 12 and causing danger or environmental pollution, in a possible embodiment, please continue to refer to Figure 1 , a drainage hole 14 can be set at the bottom plate 13.

[0048] Furthermore, the drain hole 14 is connected to an external waste liquid collection container.

[0049] In order to facilitate the fixation of the infusion mechanism 20 , a corresponding bracket may be provided inside the cabinet 10 .

[0050] Exemplarily, two mounting columns and a mounting beam connected to the two mounting columns are provided inside the cabinet 10 above the bottom plate, and the sampling tube 21 in the infusion mechanism 20 is fixed to the mounting beam so that the sampling end 211 extends downward and is located above the bottom plate 13.

[0051] Furthermore, in order to facilitate the sampling tube 21 to pass through the cabinet 10 and connect to an external liquid supply device, in a possible embodiment, a through hole can be opened on the top plate of the cabinet 10 to pass the top end of the sampling tube 21 away from the sampling end 211 out of the cabinet 10.

[0052] The infusion mechanism 20 includes a sampling tube 21 for transporting the sample liquid.

[0053] Further, in some possible embodiments, please continue to refer to Figure 1 and Figure 2 , the infusion mechanism 20 further includes a valve 22. The valve 22 is disposed on the sampling tube 21.

[0054] When sampling is required, the container 2 can be placed on the bottom plate 13 and below the sampling end 211, and then the turntable 31 is rotated to rotate the transparent baffle 32 to the opening 12 to separate the container 2 and the sampling tube 21 from the opening 12, and then the valve 22 is opened to transport the sample liquid into the container 2.

[0055] The anti-splash mechanism 30 has a transparent baffle 32. The transparent baffle 32 is used to separate the container 2 and the sampling tube 21 from the opening 12 during sampling, block the sample liquid splashed during sampling, and reduce the probability of the sample liquid splashing outside the opening 12 and causing danger to the operator and polluting the environment.

[0056] To facilitate the operator to place and remove the container 2 from the opening 12, the anti-splash mechanism 30 is further provided with a turntable 31. The turntable 31 is rotatably connected to the inner wall of the cabinet body 10. The transparent baffle 32 is fixedly connected to the turntable 31. The transparent baffle 32 can be rotated to the opening 12 by rotating the turntable 31 to block the splashing sample liquid, or the transparent baffle 32 can be rotated to a position far away from the opening 12 by rotating the turntable 31 to facilitate placing or removing the container 2.

[0057] To improve the anti-splash effect of the transparent baffle 32, in some possible embodiments, the bottom end of the transparent baffle 32 extends below the middle of the container 2.

[0058] If the bottom end of the transparent baffle 32 is above the middle of the container 2 and close to the interface of the container 2, the sample liquid is likely to pass through the bottom end of the transparent baffle 32 and outside the opening 12.

[0059] Further, to improve the rotational smoothness of the transparent baffle 32, in some possible embodiments, the bottom end of the transparent baffle 32 is spaced a certain distance from the bottom plate 13, and the bottom end of the transparent baffle 32 does not exceed above the middle of the container 2.

[0060] If the bottom end of the transparent baffle 32 contacts the bottom plate 13, and if there are sample liquid residues attached to the bottom plate 13, it will affect the rotational smoothness of the transparent baffle 32.

[0061] To further improve the rotational smoothness of the transparent baffle 32, the transparent baffle 32 can be set as an arc-shaped plate.

[0062] This application does not limit how the turntable 31 is rotatably connected to the inner wall of the cabinet body 10. In some possible embodiments, please continue to refer toFigure 1 , Figure 2 and Figure 3 A partition 33 is provided in the cabinet 10, and the partition 33 is fixed to the inner wall of the cabinet 10 and is located above the bottom plate 13. The partition 33 is provided with a first through hole 331, and the sampling end 211 of the sampling tube 21 passes through the first through hole 331 and is located below the partition 33. The turntable 31 is rotatably connected to the partition 33 and is located below the partition 33, and the transparent baffle 32 is located on the side of the turntable 31 away from the partition 33.

[0063] The sampling end 211 of the sampling tube 21 and the transparent baffle 32 are both located below the partition 33, so as to facilitate the delivery of the sample liquid to the container 2 placed on the bottom plate 13 below the partition 33 and to prevent splashing.

[0064] Further, in order to facilitate the rotation connection between the turntable 31 and the partition plate 33, in some possible embodiments, please continue to refer to Figure 3 A mounting groove 333 may be provided on one side of the partition 33 facing the bottom plate 13, and a round platform 334 with a small top and a large bottom is protruded downward in the mounting groove 333. The turntable 31 is provided with a second through hole 311 that fits with the round platform 334. The turntable 31 is arranged in the mounting groove 333, and the hole wall of the second through hole 311 is sleeved outside the round platform 334 and is rotatably engaged with the round platform 334.

[0065] It is understandable that the second through hole 311 is also truncated in shape, and the inner diameter of the upper end of the second through hole 311 is smaller than the inner diameter of the lower end. When the turntable 31 is sleeved outside the truncated platform 334 through the hole wall of the second through hole 311, since the inner diameter of the upper end of the second through hole 311 is smaller than the outer diameter of the lower end of the truncated platform 334, the turntable 31 can be rotatably engaged with the truncated platform 334 to prevent the turntable 31 from falling downward.

[0066] Furthermore, the round platform 334 can be detachably connected to the partition plate 33 via studs.

[0067] Further, in order to facilitate the operation of the operator, in a possible embodiment, please continue to refer to Figure 1 and Figure 2 A paddle 36 may be protrudingly provided on a side of the transparent baffle 32 away from the sampling tube 21 .

[0068] When the transparent baffle 32 needs to be rotated to the opening 12 or away from the opening 12 , the operator can push the paddle 36 to rotate the transparent baffle 32 .

[0069] Further, in order to improve the convenience of operation and prevent the paddle 36 from rotating with the transparent baffle 32 and the turntable 31 to the position between the transparent baffle 32 and the inner wall of the cabinet 10 in the accommodating cavity 11, in some possible embodiments, please combine Figure 1 and Figure 2, an arc-shaped slideway 332 can be provided at the partition plate 33, and a slide post 34 is provided on the upper side of the turntable 31. The slide post 34 extends into the arc-shaped slideway 332 and can slide along the arc-shaped slideway 332 selectively.

[0070] Since the slide post 34 cannot slide out of the arc-shaped slideway 332, the cooperation between the slide post 34 and the arc-shaped slideway 332 can be used to limit the rotation angles of the turntable 31 and the transparent baffle 32.

[0071] In some possible embodiments, please continue to refer to Figure 3 , the turntable 31 can be set as a disc, and a first arc-shaped boss 312 protrudes radially from the side surface of the disc. The cross-section of the installation groove 333 is circular, and a second arc-shaped boss 335 protrudes radially from the side surface of the installation groove 333 towards the disc, so that the first arc-shaped boss 312 can selectively abut against the two ends of the second arc-shaped boss 335 as the turntable 31 rotates.

[0072] Moreover, the arc length of the second arc-shaped boss 335 can be set to be the same as the arc length of the arc-shaped slideway 332. The rotation angles of the turntable 31 and the transparent baffle 32 can be jointly limited through the cooperation between the first arc-shaped boss 312 and the second arc-shaped boss 335 and the cooperation between the arc-shaped slideway 332 and the slide post 34.

[0073] When the slide post 34 is located at the starting end of the arc-shaped slideway 332, the first arc-shaped boss 312 abuts against the first end of the second arc-shaped boss 335; when the slide post 34 is located at the terminating end of the arc-shaped slideway 332, the first arc-shaped boss 312 abuts against the second end of the second arc-shaped boss 335.

[0074] Furthermore, in some possible embodiments, threads are provided along the extending direction of the arc-shaped slideway 332 on the inner wall of the arc-shaped slideway 332, and the slide post 34 is set as a stud.

[0075] When the turntable 31 needs to be rotated, the stud can be screwed to move the stud along the threads of the arc-shaped slideway 332 in the extending direction of the arc-shaped slideway 332, and then drive the turntable 31 to rotate through the sliding of the stud in the extending direction of the arc-shaped slideway 332.

[0076] Furthermore, in order to facilitate the operator to rotate the stud, in a possible embodiment, please continue to refer to Figure 1 , the top end of the stud can penetrate outside the arc-shaped slideway 332 and be located above the partition plate 33, and a knob 35 is provided at the top end of the stud.

[0077] The operator can rotate the knob 35 to move the stud along the arc-shaped slideway 332.

[0078] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
