Description

Technical Field

[0001] The utility model relates to the technical field of extractors, and in particular to a rapid solvent extractor with a quantitative function. Background Art

[0002] The extractor can extract the required compounds from solid or liquid mixtures through extraction, thereby purifying and purifying the compounds. There are many types of extractors. With the maturity of technology, rapid solvent extractors are mostly used in the market. Rapid solvent extractors are unit operations that use the different solubilities of components in the system in the solvent to separate the mixture. They use the different solubility or distribution coefficients of substances in two immiscible solvents to transfer solute substances from one solvent to another. They are widely used in chemical, metallurgical, food and other industries, and are commonly used in petroleum refining industries. Existing rapid solvent extractors have a quantitative function. After the liquid is mixed, it is allowed to stand and stratify, and solutions of different compositions are removed.

[0003] Extractors are also commonly used in water quality testing. Existing separatory funnels are mostly one-piece structures. The water sample to be tested is mixed with a specific solution and placed on a static rack for stratification. After stratification, the liquid in the lower layer is poured out from the bottom of the separatory funnel, and the liquid in the upper layer is poured out from the top of the separatory funnel. During the operation, the separatory funnel needs to be removed from the static rack and rotated, which is extremely inconvenient. For this reason, a rapid solvent extractor with quantitative function is proposed, which can solve the above problem by turning the separatory funnel on the rack through a rotatable side plate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1~Figure 4 As shown, this embodiment proposes a rapid solvent extractor with quantitative function, including a mounting plate 1, one side of the mounting plate 1 is rotatably connected to a rotating rod 2, one end of the rotating rod 2 is fixedly connected to a side plate 3, the side plate 3 is U-shaped and is provided with two clamping jaws, a separating funnel 4 is clamped between the two clamping jaws, and control valves 5 are movably connected to the pipe openings of both ends of the separating funnel 4, a fixing plate 6 is fixedly connected to the inner wall of one side of the mounting plate 1, a positioning rod 7 is symmetrically slidably connected to the inner wall of one side of the mounting plate 1, a screw 8 is threadedly connected between the two positioning rods 7, an upper clamping tube 9 is fixedly connected to the outer end of one of the positioning rods 7, and a lower clamping ring 10 is fixedly connected to the outer end of the other positioning rod 7, and the screw 8 is rotatably connected to the fixing plate 6. The purpose of this arrangement is that the U-shaped side plate 3 and the clamping claws at both ends can clamp and fix the two ports of the separating funnel 4. At the same time, the outer end of the side plate 3 is fixedly connected to the mounting plate 1 which rotates with the mounting plate 1, so that the separating funnel 4 can be flipped inside the mounting plate 1. When pouring the upper layer of liquid in the separating funnel 4, it is only necessary to flip the separating funnel 4 without disassembling the separating funnel 4, and the separation operation is simpler.

[0028] Preferably, the diameters of the two ends of the separating funnel 4 are the same, and the inner diameter of the upper clamping tube 9 and the inner diameter of the lower clamping ring 10 are the same as the outer diameter of the tube opening of the separating funnel 4. The purpose of this arrangement is that, since the outer diameter of the tube opening of the separating funnel 4 is the same as the inner diameter of the upper clamping tube 9 and the lower clamping ring 10, it has a clamping effect on the one hand, and has a sealing effect on the port of the separating funnel 4 on the other hand.

[0029] Preferably, the outer end of the screw 8 is provided with two sets of threads and are arranged in opposite directions, and a liquid separation tube 11 is slidably connected to the interior of the lower clamp ring 10, and the outer circle radius of the liquid separation tube 11 is the same as the inner circle radius of the lower clamp ring 10. The purpose of this arrangement is that the liquid separation tube 11 is used to pour the liquid in the separatory funnel 4, so as to facilitate the recovery of the layered liquid.

[0030] In this embodiment, the water sample to be tested is mixed with the solvent and oscillated, then passed into the separating funnel 4 for standing and stratification. After the solution is stood, stratification occurs. At this time, the control valve 5 at the lower port position of the separating funnel 4 is opened to discharge the liquid in the lower layer of the separating funnel 4. When separating the upper layer of liquid, the screw 8 is rotated, and the screw 8 drives the upper clamping tube 9 and the lower clamping ring 10 connected to the positioning rod 7 to move in opposite directions, so that the upper clamping tube 9 and the lower clamping ring 10 are respectively separated from the two ports of the separating funnel 4. At this time, the rotating rod 2 is rotated again, and the clamping claws at the outer end of the side plate 3 drive the separating funnel 4 to rotate 180 degrees, so that the upper port of the separating funnel 4 is facing downward, and the upper port of the separating funnel 4 is connected to the separating tube 11, and then the liquid in the upper layer of the separating funnel 4 is discharged. The operation is simple and there is no need to disassemble the separating funnel 4.

[0033] Preferably, the top of the mixing tank 12 is fixedly connected with an addition tank 13 and a filtrate tank 14, both of which are made of transparent materials, and scales are provided at the outer ends of the addition tank 13 and the filtrate tank 14. The purpose of this arrangement is that the addition tank 13 and the filtrate tank 14 made of transparent materials can penetrate the solution content inside the tank, and the scales are provided to facilitate reading the addition amount of the solvent and the water sample to be tested.

[0034] Preferably, the filtrate tank 14 is a topless cylindrical structure, a filter plate is clamped inside the filtrate tank 14, and a flow magnetic valve is movably connected to the connecting pipe of the addition tank 13 and the filtrate tank 14. The purpose of this arrangement is that the flow magnetic valve is convenient for quantitatively discharging the solution and improving the accuracy of extraction.

[0035] Preferably, a servo motor 15 is fixedly connected to the top of the mixing tank 12, an output pipe of the servo motor 15 penetrates the mixing tank 12 and is rotatably connected thereto, a support shaft 16 is fixedly connected to the output end of the servo motor 15, and a double-screw stirring blade 17 is fixedly connected to the outer end of the support shaft 16. The purpose of this arrangement is that the servo motor 15 can drive the support shaft 16 and the double-screw stirring blade 17 at the outer end thereof to rotate, thereby stirring the mixed liquid inside the mixing tank 12 and improving the effect of mixing multiple solutions.

[0036] Preferably, the outer end of the support shaft 16 is fixedly connected with an auger 18, and the auger 18 is arranged inside the double-screw stirring blade 17. The purpose of this arrangement is that the auger 18 is used to drive the substance that is difficult to dissolve in water at the bottom of the mixing tank 12, and pump it to the upper layer of the mixing tank 12, and then stir it through the double-screw stirring blade 17, so as to enhance the mixing effect of the substance and the solvent.

[0037] Preferably, the inner side of the mounting plate 1 is fixedly connected to a clamping rod 19, and the clamping rod 19 is fixedly connected to the liquid dispensing tube 11. The purpose of this arrangement is that the clamping rod 19 is used to fix the liquid dispensing tube 11, so as to facilitate the liquid dispensing operation.

[0038] In this embodiment, a variety of solvents and water samples to be tested are quantitatively discharged into the interior of the mixing tank 12 through the addition tank 13 and the filtrate tank 14. At this time, the servo motor 15 drives the support shaft 16 and the double-screw stirring blade 17 at its outer end to rotate, thereby stirring the mixed liquid. At the same time, the auger 18 at the outer end of the support shaft 16 pumps the precipitated water-insoluble substances to the upper layer of the mixing tank 12, and then stirs them through the double-screw stirring blade 17 to enhance the mixing effect of the material and the solvent.
