Description

Technical Field

[0001] This invention relates to separatory funnels, and more particularly to a double-layered separatory funnel. Background Technology

[0002] Separatory funnels are used for liquid sample extraction. If stratification occurs within the funnel, the upper and lower layers need to be poured out separately to prevent mixing and ensure extraction accuracy. This repeated pouring increases the frequency of contact with the external environment, which can easily contaminate the extracted liquid. Similarly, when extracting aqueous and oil phases separately, pre-separation is necessary to improve extraction accuracy and reduce contamination. Therefore, a key challenge for separatory funnels is how to separate the aqueous and oil phases near the stratification threshold while minimizing contact with the external environment and allowing for the separate pouring out of both phases in one step.

[0003] Therefore, the existing separatory funnel needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a double-layered separatory funnel that can quickly separate the aqueous and oil phases based on the boundary line, allowing for rapid extraction of the aqueous and oil phases. This reduces the contact time between the oil and aqueous phases and the external environment during the separation process, thereby reducing contamination, improving separation accuracy, and minimizing mixing of the oil phase during separation.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A double-layered separating funnel includes an upper separating container and a lower separating container, with a switching channel provided between the upper and lower separating containers. Each of the upper and lower separating containers is equipped with an air inlet valve, an upper interface, and a lower interface, each with a detachable stopper structure and a liquid outlet connection cap.

[0007] Furthermore, the inner walls of the upper interface and the lower interface are configured as inner cones, and the outer walls of the upper interface and the lower interface are configured as outer cones.

[0008] Furthermore, the outer wall of the plug structure is cone-shaped, and the inner wall of the liquid outlet connection cap is cone-shaped.

[0009] Furthermore, the switching channel includes a connecting channel disposed between the upper and lower liquid distribution containers, and a switching valve is provided on the connecting channel.

[0010] Furthermore, the upper liquid distribution container includes an upper cylinder, a central connecting plate is provided in the middle of the upper cylinder, a plurality of liquid guiding holes are provided on the central connecting plate, and a bottom float is provided at the bottom of the central connecting plate; the lower liquid distribution container includes a lower cylinder sleeved on the outer wall of the upper cylinder, and a spacer structure is provided at the lower end of the upper cylinder.

[0011] The partition structure divides the internal space of the upper cylinder and the lower cylinder into an upper liquid chamber and a lower liquid chamber with adjustable space size.

[0012] Furthermore, the density of the bottom float is less than the density of water.

[0013] Furthermore, the interval structure includes a closed bottom plate disposed at the lower end of the upper cylinder, a flow guiding channel disposed on the closed bottom plate, a closing structure disposed on the closed bottom plate for closing the flow guiding channel, and an external control structure disposed on the outer surface of the lower cylinder for controlling the opening or closing of the closing structure.

[0014] Furthermore, the external control structure includes an adjusting rotating ring disposed on the outer circumference of the lower cylinder, a positive magnet disposed on one inner wall of the adjusting rotating ring, a straight guide groove disposed on the lower surface of the closed bottom plate, a strip-shaped sealing plate movably disposed in the straight guide groove, and a negative magnet disposed at each end of the strip-shaped sealing plate that can move in coordination with the positive magnet.

[0015] In summary, the advantages of this invention over the prior art are:

[0016] This invention addresses the shortcomings of existing separating funnels. Through its structural design, it offers the following advantages: it effectively separates the oil and water phases within the separating funnel, placing the water phase below and the oil phase above, thus achieving complete separation within the funnel and reducing contamination from external contact during pouring. Furthermore, this invention automatically detects the boundary between the oil and water phases and automatically adjusts the vertical position of the barrier structure for precise separation. After positioning, it allows for both open and closed operation via an external control structure. This external control structure can control the separating structure at any height, and the design is simple and easy to use. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 This invention provides

[0023] A double-layer isolation liquid separating funnel includes an upper liquid separating container 1 and a lower liquid separating container 2. A switch channel 3 is provided between the upper liquid separating container 1 and the lower liquid separating container 2. An air inlet valve 4 is provided on each of the upper liquid separating container 1 and the lower liquid separating container 2. An upper interface 5 and a lower interface 6 are respectively provided on the upper liquid separating container 1 and the lower liquid separating container 2. A detachable plug structure 7 and a liquid outlet connection cap 8 are provided on each of the upper interface 5 and the lower interface 6.

[0024] The working principle of the above structure is as follows:

[0025] Due to their different densities, the oil phase and the water phase are stored in the separatory funnel. The denser water settles in the lower separatory container 2, while the less dense oil floats in the upper separatory container 1.

[0026] At this time, by controlling the switch channel 3, the switch channel 3 can isolate the upper liquid separation container 1 and the lower liquid separation container 2, thereby separating the oil phase and the water phase.

[0027] At this time, the intake pipe valve 4 of the separated oil phase and water phase is opened, and the intake pipe valve 4 is a one-way valve.

[0028] This allows external gas to enter the upper liquid separator 1 and the lower liquid separator 2 to be discharged.

[0029] Reduce the possibility of contact with the outside world during the separation and extraction process, and reduce contamination.

[0030] The inner walls of the upper interface 5 and the lower interface 6 of the present invention are inner conical, and the outer walls of the upper interface 5 and the lower interface 6 are outer conical.

[0031] The outer wall of the plug structure 7 of the present invention is set in an outer conical shape, and the inner wall of the liquid outlet connection cap 8 is set in an inner conical shape.

[0032] The switching channel 3 of the present invention includes a connecting channel 301 disposed between the upper liquid distribution container 1 and the lower liquid distribution container 2, and a switching valve 302 is disposed on the connecting channel 301.

[0033] The upper liquid distribution container 1 of the present invention includes an upper cylinder 101, a middle connecting plate 102 is provided in the middle of the upper cylinder 101, a plurality of liquid guiding holes 103 are provided on the middle connecting plate 102, and a bottom float plate 104 is provided at the bottom of the middle connecting plate 102; the lower liquid distribution container 2 includes a lower cylinder 201 sleeved on the outer wall of the upper cylinder 101, and a spacer structure 202 is provided at the lower end of the upper cylinder 101;

[0034] The bottom float 104 has a density greater than that of the oil phase and less than that of the water phase, and floats between the water phase and the oil phase. At this time, when the partition structure 202 is operated, it can be accurately aligned with the position where the oil phase and the water phase are separated.

[0035] Since the water phase and oil phase have different capacities, the water level may be higher or lower. Therefore, the bottom float 104 is also adjusted in height according to the water phase height.

[0036] The external control structure 2024 can control the partition structure 202 at any height to perform a sealing operation, reducing contact with the outside air.

[0037] The partition structure 202 divides the internal space of the upper cylinder 101 and the lower cylinder 201 into an upper liquid chamber 203 and a lower liquid chamber 204 with adjustable space size.

[0038] The density of the bottom floating plate 104 described in this invention is less than the density of water.

[0039] The interval structure 202 of the present invention includes a closed bottom plate 2021 disposed at the lower end of the upper cylinder 101, a flow guiding channel 2022 disposed on the closed bottom plate 2021, a closing structure 2023 disposed on the closed bottom plate 2021 for closing the flow guiding channel 2022, and an external control structure 2024 disposed on the outer surface of the lower cylinder 201 for controlling the opening or closing of the closing structure 2023;

[0040] The external control structure 2024 of the present invention includes an adjusting rotating ring 2025 disposed on the outer circumferential wall of the lower cylinder 201. A positive magnet 2026 is disposed on one inner wall of the adjusting rotating ring 2025. A straight guide groove 2027 is disposed on the lower surface of the closed bottom plate 2021. A strip-shaped sealing plate 2028 is movably disposed in the straight guide groove 2027. A negative magnet 2029 is disposed at each end of the strip-shaped sealing plate 2028, which can move in cooperation with the positive magnet 2026.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
