Description

Technical Field

[0001] This utility model relates to the field of wastewater detection technology, specifically to an extraction device for detecting anionic surfactants in wastewater. Background Technology

[0002] The main purpose of detecting anionic surfactants in wastewater is to assess the water pollution status and provide a scientific basis for pollution control and water quality management. Specifically, this includes: assessing the degree of pollution, ensuring ecological safety, monitoring health risks, and supporting pollution control.

[0003] Extraction methods for detecting anionic surfactants in wastewater mainly include liquid-liquid extraction (LLE) and solid-phase extraction (SPE). The specific choice depends on the detection requirements, sample characteristics, and laboratory conditions. When performing extraction using LLE, personnel need to frequently shake multiple funnels to mix the additives added to the funnels. Manual shaking is time-consuming and laborious. Therefore, an extraction device for detecting anionic surfactants in wastewater is proposed. The device uses a drive motor to rotate the column, which in turn rotates the funnels in the circular shelf and circular channel. This allows the sample and additives in the funnels to be mixed evenly without manual shaking. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an extraction device for detecting anionic surfactants in wastewater. The device uses a drive motor to rotate the column, which in turn rotates the circular layer and the funnel in the circular channel. This allows the sample and additives in the funnel to be mixed evenly without manual shaking.

[0005] The technical solution adopted by this utility model to solve its technical problem is an extraction device for detecting anionic surfactants in wastewater, including a circular base, a column rotatably connected inside the circular base through a bearing, a drive motor installed inside the circular base on one side of the column through a mounting bracket, a circular shelf fixed to the top of the column through a flange, and circular through slots equidistantly opened on the top of the circular shelf.

[0006] The top of the circular shelf is provided with a telescopic assembly, which includes a cylinder fixed to the top of the circular shelf by a flange. A connecting rod is sleeved on the top of the cylinder. A limit plate is fixed to the bottom of the connecting rod inside the cylinder by bolts. A compression spring is sleeved on the outside of the top of the limit plate. A cover assembly is provided on the top of the connecting rod.

[0007] By adopting the above technical solution, the drive motor drives the column and the circular plate at its top to rotate, which can drive the separatory funnel inserted into the circular through groove to rotate, which can shake the melt in the separatory funnel evenly. The compression spring can push the connecting rod down, thereby driving the capping assembly to cap the separatory funnel.

[0008] Specifically, the column is located on the outer side of the circular base and is fixedly fitted with a gear ring by a flat key. The top output shaft of the drive motor is fixedly fitted with a gear by a flat key, and the gear and the gear ring mesh with each other.

[0009] Specifically, a first protective sleeve is welded to the top of the circular base, the column penetrates through the first protective sleeve, and a rubber pad is glued to the top of the circular base outside the first protective sleeve.

[0010] Specifically, limit strips are provided on both sides of the inner side of the cylinder, and limit grooves are opened on both sides of the limit plate, with the limit grooves engaging with the outer side of the limit strips.

[0011] Specifically, the sealing assembly includes a circular block fixed to the top of the connecting rod by bolts, connecting plates are welded at equal intervals on the outer side of the circular block, and a sealing cap is welded to the end of the connecting plate away from the circular block.

[0012] Specifically, a rubber stopper is glued to the bottom of the sealing cap.

[0013] The beneficial effects of this utility model are:

[0014] (1) The extraction device for detecting anionic surfactants in wastewater described in this utility model is driven by a motor that drives the column and the circular plate at its top to rotate through gears and gear rings. This drives the separatory funnel placed in the circular channel to rotate, which can shake the molten liquid in the separatory funnel evenly without the need for manual shaking.

[0015] (2) The extraction device for detecting anionic surfactants in wastewater described in this utility model uses a compression spring to push the connecting rod and the circular block down, so that the sealing cover is placed on the separatory funnel. Pressing down the sealing cover forcefully causes the rubber stopper to be inserted into the separatory funnel, which can seal the separatory funnel and prevent the molten liquid from spilling out when it rotates.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The column is driven by a motor to rotate, which in turn rotates the circular shelf and the funnel inside the circular slot. This allows the sample and additives inside the funnel to be mixed evenly without manual shaking. Figure 1-4 As shown, the extraction device for detecting anionic surfactants in wastewater according to the present invention includes a circular base 1, a column 2 rotatably connected inside the circular base 1 via a bearing, a drive motor 6 mounted inside the circular base 1 on one side of the column 2 via a mounting bracket, a circular shelf 3 fixed to the top of the column 2 via a flange, and circular through slots 7 equidistantly opened on the top of the circular shelf 3.

[0024] The top of the circular shelf 3 is provided with a telescopic assembly 4. The telescopic assembly 4 includes a cylinder 401 fixed to the top of the circular shelf 3 by a flange. A connecting rod 402 is sleeved on the top of the cylinder 401. The bottom end of the connecting rod 402 inside the cylinder 401 is fixed with a limit plate 403 by bolts. A compression spring 404 is sleeved on the outside of the top of the limit plate 403. A capping assembly 5 is provided on the top of the connecting rod 402.

[0025] In use, the drive motor 6 drives the column 2 and the circular plate 3 at its top to rotate, which can drive the separatory funnel inserted into the circular through groove 7 to rotate, which can shake the melt in the separatory funnel evenly. The compression spring 404 can push the connecting rod 402 down, which can drive the capping assembly 5 to cap the separatory funnel.

[0026] For example, such as Figure 2 As shown, the present invention also includes a gear ring 8 fixedly sleeved on the outer side of the column 2 inside the circular base 1 by a flat key, and a gear 9 fixedly sleeved on the top output shaft of the drive motor 6 by a flat key, wherein the gear 9 and the gear ring 8 mesh with each other.

[0027] In use, the drive motor 6 drives the column 2 to rotate through the gear 9 and gear ring 8.

[0028] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a first protective sleeve 10 welded to the top of the circular base 1, the column 2 penetrating through the first protective sleeve 10, and a rubber pad 11 glued to the top of the circular base 1 outside the first protective sleeve 10.

[0029] When in use, the first protective sleeve 10 can prevent the column 2 from tilting without affecting its rotation, and the rubber pad 11 can prevent slipping and make it easy to place other funnels and volumetric flasks on the circular base 1.

[0030] For example, such as Figure 3 As shown, the present invention also includes limiting strips 405 provided on both sides of the inner side of the cylinder 401, and limiting grooves 406 provided on both sides of the limiting plate 403, the limiting grooves 406 being engaged with the outer side of the limiting strips 405.

[0031] When in use, the limiting strip 405 and the limiting groove 406 can prevent the connecting rod 402 from rotating without affecting its up and down movement.

[0032] For example, such as Figure 4 As shown, the present invention also includes a sealing assembly 5 comprising a circular block 501 fixed to the top of the connecting rod 402 by bolts, a connecting plate 502 welded equidistantly to the outer side of the circular block 501, and a sealing cap 503 welded to the end of the connecting plate 502 away from the circular block 501.

[0033] During use, the circular block 501 moves up and down, which in turn moves the sealing cover 503 via the connecting plate 502.

[0034] For example, such as Figure 4 As shown, the present invention also includes a rubber stopper 504 glued to the bottom of the sealing cap 503.

[0035] When in use, inserting the rubber stopper 504 into the separatory funnel can improve the sealing between the sealing cap 503 and the separatory funnel.

[0036] In use, the device is connected to an external power source using a power cord. Seven separating funnels are inserted into the circular groove 7 in sequence. Rubber rings 12 in the circular groove 7 provide anti-slip and protective functions. 100 ml, 99 ml, 97 ml, 95 ml, 93 ml, 91 ml and 89 ml of water are poured into the separating funnels respectively. Then, 1.00 ml, 3.00 ml, 5.00 ml, 7.00 ml, 9.00 ml and 11.00 ml of sodium linear alkylbenzene sulfonate standard solution are dripped into the separating funnels respectively. At this time, the drive motor 6 is turned on, which drives the column 2 and the circular plate 3 at its top to rotate through the gear 9 and gear ring 8, thereby driving the multiple separating funnels to rotate and shake the water and solution inside them evenly.

[0037] When adding liquid, pull the circular block 501 and the sealing cap 503 upward. After adding liquid, release the circular block 501. The compression spring 404 pushes the connecting rod 402 downward through the limiting plate 403, thereby driving the circular block 501 and the sealing cap 503 downward, so that the sealing cap 503 covers the separatory funnel. Press down the sealing cap 503 so that the rubber stopper 504 at the bottom of the separatory funnel is inserted into the separatory funnel. This can seal the funnel and prevent the water and solution inside from spilling out when the separatory funnel rotates.

[0038] After shaking the water and solution, the collected wastewater samples were poured into seven separatory funnels. Using phenolphthalein as an indicator, 1 mol of sodium hydroxide solution was added dropwise until the water in the separatory funnel turned pink. Then, 5 mol of sulfuric acid was added until the water in the separatory funnel became transparent again. 25 ml of methylene blue solution was added, and the drive motor 6 was started to shake well. After shaking well, 10 ml of chloroform was added, and the drive motor 6 was started again to shake well.

[0039] After shaking well, pull up the circular block 501 to release the gas. If emulsification occurs in the separatory funnel, add a small amount of isopropanol to eliminate the emulsification. Add the same volume of isopropanol to all separatory funnels, and let them stand to separate the layers. Transfer the chloroform layer to another funnel containing 50 ml of washing solution. Repeat the extraction three times, using 10 ml of chloroform each time. Add the chloroform from all separatory funnels to another funnel containing 50 ml of washing solution, shake well again, and let them stand to separate the layers. Pour the chloroform layer from the other funnels through absorbent cotton into a 50 ml volumetric flask, and then wash twice with chloroform, using 5 ml each time. Pour this chloroform layer into a 50 ml volumetric flask as well. The extraction is now complete for subsequent analysis.
