Description

Technical Field

[0001] This utility model relates to the field of separation devices, and in particular to a device for separating immiscible solutions. Background Technology

[0002] In industrial production, the natural separation of two immiscible liquids is often achieved by allowing them to settle, and then the two separated liquids are collected from their respective ends. A Chinese utility model patent with publication number CN214485751 U discloses a continuous separation device for immiscible liquids, comprising a mixed liquid storage tank, a low-density liquid storage tank, and a high-density liquid storage tank. The mixed liquid is injected into the mixed liquid storage tank through an inlet located at the top. After the mixed liquids separate into layers, the upper layer of lower-density liquid flows into the low-density liquid storage tank through a middle outlet, while the lower layer of higher-density liquid flows into the high-density liquid storage tank.

[0003] The inlet and outlet of the two liquids of this liquid separation device are both connected to the same mixed liquid settling tank. The mixed liquid settling tank is a general hollow storage tank. In the continuous liquid separation process, the liquid flow in the mixed liquid settling tank is relatively rapid, making it difficult to provide a stable settling and stratification environment. There is a risk that high-density liquid enters the low-density liquid outlet, or low-density liquid enters the high-density liquid outlet. Utility Model Content

[0004] The purpose of this invention is to provide a device for separating immiscible solutions that can provide a stable liquid stratification environment.

[0005] This utility model provides a device for separating immiscible liquids, comprising a first tank, a connecting pipe, and a second tank connected in sequence; the first tank is provided with a first baffle, which divides the first tank into a first chamber and a second chamber, and the first baffle has a connecting notch at the top, through which the first chamber and the second chamber are connected only; the top of the first tank is connected to the top of the second tank, the first connecting port of the connecting pipe is connected to the second chamber, and the second connecting port of the connecting pipe is connected to the second tank; the first chamber is provided with an inlet and a first outlet, and the second tank is provided with a second outlet; the horizontal height of the second connecting port, the horizontal height of the lowest point of the connecting notch, the horizontal height of the inlet, and the horizontal height of the first outlet decrease sequentially; the horizontal height of the second connecting port is higher than the horizontal height of the first connecting port and the horizontal height of the second outlet; the first chamber is configured as a meandering space, the inlet is connected to the front section of the meandering space, and the connecting notch and the first outlet are connected to the rear section of the meandering space.

[0006] As can be seen from the above scheme, the first baffle divides the first tank into a first chamber and a second chamber. The first chamber has a meandering space, which reduces the flow velocity of the mixed liquid flowing in through the inlet, providing a more stable and quiet settling environment. The connecting pipe, through the principle of a U-shaped tube, controls the liquid level in the first tank, ensuring that the liquid levels in the first and second chambers are level and higher than the lowest point of the connecting gap. The low-density liquid, which has been sufficiently settled and stratified in the first chamber, can flow smoothly through the connecting gap into the second chamber, and then into the second tank through the connecting pipe, finally flowing out through the second outlet. The inlet is located below the height of the connecting gap and in the middle position, which is more conducive to the stratification of the mixed liquid and avoids the stratification of high-density or low-density liquids forming excessively long flows that would cause disturbance. The first outlet is located near the bottom of the first chamber and at the rear of the meandering space, allowing high-density liquid to flow out. The horizontal height of both the first connecting port and the second outlet is lower than the horizontal height of the second connecting port, preventing the liquid from being unable to flow in if it is higher than the liquid level in the first tank.

[0007] The preferred option is that the horizontal height of the second connector is adjustable.

[0008] Therefore, the second horizontally adjustable connection port can be used to adjust and change the liquid level above the lowest point of the connection gap in the first tank, so that the liquid level is maintained at a reasonable height, avoiding the impact of excessively high or low levels on the separation effect and efficiency of the mixed liquid.

[0009] A further solution is that one end of the connecting pipe includes a pipe opening and a pipe sleeve, with the pipe sleeve screwed onto the outer wall of the pipe opening. The end of the pipe sleeve forms a second connecting port, and the horizontal height of the second connecting port can be adjusted by changing the screwing position of the pipe sleeve on the outer wall of the pipe opening.

[0010] Therefore, adjusting the screw position of the sleeve can change the horizontal height of the second connection port.

[0011] A further option is to have a second baffle inside the first chamber to form a meandering space, with the liquid inlet located on one side of the second baffle, and the connecting gap and the first liquid outlet located on the other side of the second baffle.

[0012] As can be seen, the second baffle can change the path of liquid flow. The inlet where the liquid flow is most rapid is set on one side of the second baffle, while the connecting gap and the first outlet are set on the other side. This allows the energy of the liquid flow to dissipate in the collision with the second baffle, thus accelerating the liquid stratification.

[0013] A further design involves a second baffle forming an angle with the first baffle, which divides the first chamber into a first cavity and a second cavity. The first cavity and the second cavity are connected to the space above the second baffle, and the first cavity and the second cavity are connected to the space on the side of the second baffle away from the first baffle. The liquid inlet is located in the first cavity, and the first liquid outlet and the connecting notch are located in the second cavity.

[0014] It is evident that the mixed liquid can only enter the first outlet or connecting gap by going around to the side of the second baffle away from the first baffle or rising above the second baffle, thereby fully dissipating the energy of the liquid flow.

[0015] A further proposed approach is to make the horizontal height difference between the lowest point of the connecting gap and the bottom of the first chamber between 1.1 and 3 times the horizontal height difference between the inlet and the bottom of the first chamber.

[0016] It can be seen that the mixed liquid input at the inlet is set at different positions in the middle according to the different ratios of high-density liquid and low-density liquid, so that when the high-density liquid flows to the bottom and the low-density liquid flows to the top, the high-density liquid and the low-density liquid will not mix excessively, which is more conducive to the separation of high-density liquid and low-density liquid.

[0017] A further option is to connect the second liquid outlet to the pumping unit, which can then draw liquid from the second tank through the second liquid outlet.

[0018] Therefore, the pump unit can draw low-density liquid from the second tank.

[0019] A further option is to install a level gauge inside the second tank, with the level gauge's height being lower than the height of the second connecting port.

[0020] Therefore, the level gauge can detect the horizontal height of the low-density liquid in the second tank, preventing the horizontal height from exceeding the horizontal height of the second connecting port, which would cause the liquid level in the first tank to be too high and result in poor separation of the mixed liquid.

[0021] A further option is to install a density meter inside the second tank, with the density meter positioned at a lower level than the liquid level gauge.

[0022] Therefore, the hydrometer can detect the density of low-density liquid in the second tank and can promptly sound an alarm when high-density liquid is mixed in. Attached Figure Description

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1 to 5 As shown, it should be noted that, among them Figures 1 to 4 The outer shells of the first tank 1 and the second tank 2 are made transparent and shown in dashed lines. This embodiment provides a device for separating immiscible liquids, including a first tank 1, a connecting pipe 31 and a second tank 2 connected in sequence. Both the first tank 1 and the second tank 2 are sealed tanks. The top of the first tank 1 and the top of the second tank 2 are connected by an air connecting pipe 32. A first baffle 11 is provided inside the first tank 1, which divides the first tank 1 into a first chamber 12 and a second chamber 13. A connecting notch 111 is provided on one side of the top of the first baffle 11. The first chamber 12 and the second chamber 13 are connected only through the connecting notch 111. The first connecting port 311 of the connecting pipe 31 is connected to the bottom of the second chamber 13, and the second connecting port 312 of the connecting pipe 31 is connected to the bottom of the second tank 2 and extends upward into the interior of the second tank 2. The horizontal height of the second connecting port 312 is higher than the horizontal height of the lowest point of the connecting notch 111. By using the U-tube principle, the horizontal height of the liquid level in the first chamber 12 and the second chamber 13 is equal to the horizontal height of the second connecting port 312, and the low-density liquid above the first chamber 12 can flow slowly and smoothly into the second chamber 13.

[0031] like Figure 5As shown, one end of the connecting pipe 31 includes a pipe opening 313 and a pipe sleeve 314. The outer wall of the pipe opening 313 and the inner wall of the pipe sleeve 314 are both provided with threads, and the axial direction of the threads is perpendicular to the horizontal plane. The pipe sleeve 314 can be screwed to the outer wall of the pipe opening 313. The end of the pipe sleeve 314 forms a second connecting port 312. By rotating the pipe sleeve 314, the screwed position of the pipe sleeve 314 at the pipe opening 313 can be changed, thereby changing the horizontal height of the second connecting port 312, and thus adjusting the horizontal height of the liquid level in the first tank 1.

[0032] A second baffle 14 is also provided in the first chamber 12 of the first tank body 1, such as Figure 1 , Figure 2 and Figure 4 As shown, the second baffle 14 is perpendicularly connected to the first baffle 11, dividing the first chamber 12 into a first cavity 121 and a second cavity 122. The upper part of the second baffle 14 and the side away from the first baffle 11 are both clearance spaces 123. The first cavity 121 and the second cavity 122 are connected to the clearance spaces 123, forming a meandering space. An inlet 41 for injecting the mixed liquid into the first tank 1 is located on the side wall of the first tank 1 and in the first cavity 121. A first outlet 42 for discharging high-density liquid is located on the side wall of the first tank 1 and in the second cavity 122. The inlet 41 is located in the middle, while the first outlet 42 is located lower than the inlet 41 to facilitate the discharge of the high-density liquid. In addition, the connecting gap 111 is also located in the second cavity 122. The mixed liquid entering the first chamber 12 through the liquid inlet 41 needs to go around the second baffle 14 and be fully stratified. The low-density liquid enters the second chamber 13 through the connecting gap 111, while the high-density liquid flows out through the first liquid outlet 42.

[0033] In this embodiment, a second liquid outlet 43 is provided at the bottom of the second tank 2. The second liquid outlet 43 is connected to the liquid outlet conduit 33 and to a pumping unit. The pumping unit can draw low-density liquid from the second tank 2 through the liquid outlet conduit 33 and the second liquid outlet 43.

[0034] In this embodiment, the immiscible liquid separation device injects a mixed liquid into the first chamber 121 through the inlet 41. The mixed liquid is fully stratified in the first chamber 121 and the second chamber 122. The high-density liquid that settles at the bottom flows out from the first outlet 42, while the low-density liquid that floats at the top flows smoothly through the connecting gap 111 and into the second chamber 13. When the pumping unit draws liquid through the second outlet 43, since the first tank 1 and the second tank 2 are connected sealed spaces, the low-density liquid will be drawn from the second chamber 13 to the second connecting port 312 of the connecting pipe 31 in the second tank 2 and flow out into the second tank 2. Finally, it will be drawn away by the pumping unit from the second outlet 43.

[0035] In this embodiment, a level gauge and a density gauge are installed inside the second tank 2. The level gauge is at a lower level than the second connecting port 312, and the density gauge is at a lower level than the level gauge and is located below the surface of the low-density liquid inside the second tank 2.

[0036] In other embodiments, the inlet is connected to a first liquid pump, and the outlet is connected to a second liquid pump. By adjusting the power of the first liquid pump, the second liquid pump, and the pumping unit, the liquid flow rate of each liquid inlet and outlet can be controlled, thereby adapting to mixed liquids with different ratios of high-density liquid and low-density liquid.

[0037] In other embodiments, multiple baffles may be provided in the first chamber to form a more meandering space with multiple bends, slowing down the flow rate of the mixed liquid and allowing the mixed liquid to stratify faster and better.

[0038] The above embodiments illustrate only one implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
