[0046] In a feasible embodiment, the pipe opening of the modular clarifier further comprises one or more sight glasses, which are used to observe the state of the water phase and the organic phase in the clarifier.

[0047] Embodiment 3: Modular connecting assembly 3 Figure 7 is a perspective view of an embodiment of the modular connecting assembly according to the present application, as shown in Figure 7 , Figure 6 and Figure 1 , the modular connecting assembly 3 comprises a first modular connecting assembly 31 and a second modular connecting assembly 32: The first modular connecting assembly 31 is arranged between the modular mixing chamber 1 and the modular clarifier 2; The second modular connecting assembly 32 is arranged in the modular clarifier or / and the pipe opening 4, which is used for the connection of the components in the modular clarifier or / and the connection between the inside and outside of the pipe opening 4.

[0048] In a feasible embodiment, the modular connecting assembly 3 comprises one or more of the overflow box 310, the flow guide pipe 321, the flow guide box, the pipe 41 and the flange 42.

[0049] In a preferred embodiment, as shown in Figure 7 , the first modular connecting assembly 31 comprises an overflow box 310, as shown in 1 and Figure 3 , a first through slot 101 is arranged on the barrel 10 of the modular mixing chamber; a second through slot 201 is arranged on the tank body 20 of the modular clarifier, one end of the overflow box 310 is in communication with the first through slot 101, and the other end of the overflow box 310 is in communication with the second through slot 201.

[0050] The modular mixing chamber and modular clarification chamber of this invention are connected by a flow channel, which is more conducive to fluid transmission, saves pipelines, and reduces costs.

[0051] In a preferred embodiment, the size of the other end of the flow box 310 is larger than the size of the first end.

[0052] In a preferred embodiment, the height of the first through groove 101 is greater than the height of the second through groove 201, such that the height of one end of the flow box 310 connected between the two is greater than the height of the other end, that is, the flow box 310 is tilted toward the modular clarifier.

[0053] In one feasible embodiment, such as Figure 7 As shown, the flow box 310 also includes at least one partition 311, which is disposed in the hollow cavity of the flow box 310.

[0054] In one feasible embodiment, the flow box 310 is also provided with an observation window 312, and preferably, a water seal 6 is provided around the observation window 312.

[0055] In one feasible embodiment, such as Figure 6 As shown, the second modular connection assembly 32 includes a flow guide pipe 321, a first flow guide box 322, and a second flow guide box 323. The inlet of the modular clarification chamber also includes a return port 213. The guide pipe 321 serves as an organic reflux pipe, with one end connected to the organic reflux zone (middle of the organic weir) and the other end connected to the reflux port 213. The organic phase returns to the mixing chamber through the guide pipe. This is suitable for situations where the ratio of organic phase to water phase in the mixing chamber is relatively small compared to the ratio corresponding to the optimal extraction efficiency. The organic phase collected by the organic weir in the modular clarification chamber is refluxed back to the modular mixing chamber, so that the ratio of organic phase to water phase reaches the ratio corresponding to the optimal extraction efficiency. One end of the first flow guide box 322 is connected to one end outlet of the organic weir 23, and the other end is connected to the organic phase outlet 212, thereby guiding the organic phase from the organic weir end to the front end of the clarification chamber, and then the organic phase enters the next stage through the interstage pipe; One end of the second flow guide box 323 is connected to the space corresponding to the water phase adjustment component 24, and the other end is connected to the water phase outlet 211, thereby guiding the water phase from the rear end of the water phase adjustment to the front end of the clarification chamber, and then the water phase enters the next stage through the interstage pipe.

[0056] In one feasible embodiment, one end of the guide pipe is connected to the water phase reflux area corresponding to the water phase adjustment component, and the other end is connected to the reflux port. The water phase returns to the mixing chamber through the guide pipe, which serves as a reflux pipe. This is suitable for situations where there is insufficient water phase in the mixing chamber.

[0057] The present application sets a flow guide box and a flow guide pipe (a reflux pipe) inside the clarifying chamber, which is an internal inter-stage pipe. Only a small amount of pipes arranged in front of the clarifying chamber can complete the connection of the inter-stage pipes. The internal space of the extraction tank clarifying chamber is fully utilized, and the flow guide boxes or pipes of the water phase and the organic phase (for example, the oil phase) are made on both sides of the internal space to replace the internal inter-stage pipes. All external inter-stage pipes are arranged in front of the clarifying chamber, and a small amount of pipes can complete the connection of each stage, which greatly reduces the installation engineering quantity of the inter-stage pipes and shortens the installation time, and provides great convenience for the subsequent pipe maintenance.

[0058] In one specific embodiment of the present application, the size of the clarifying chamber is 7200 mm x 3000 mm x 1300 mm (length x width x height), a 200 mm x 200 mm square organic inter-stage flow guide box is arranged on one side of the clarifying chamber, and the flow guide is from the organic weir bottom plate to the organic phase outlet at the front plate of the clarifying chamber; another 200 mm x 200 mm square water phase inter-stage flow guide box is arranged on the other side of the clarifying chamber, and the flow guide is from the water phase space after adjustment to the water phase outlet at the front plate of the clarifying chamber; the organic reflux pipe (flow guide pipe) starts from the organic weir bottom plate, is first connected to the top of the bottom plate close to the bottom plate, and then is connected to the reflux port at the front plate of the clarifying chamber along the bottom plate; the overflow box between the mixing chamber and the clarifying chamber is extended to 1.2 meters, and the mixing chamber is provided with pipe openings of the organic phase, the water phase and the reflux.

[0059] In another specific embodiment of the present application, the size of the clarifying chamber is 6000 mm x 2400 mm x 1300 mm, a 180 mm x 180 mm square organic inter-stage flow guide box is arranged on one side of the clarifying chamber, and the flow guide is from the organic weir bottom plate to the organic phase outlet at the front plate of the clarifying chamber; another 180 mm x 180 mm square water phase inter-stage flow guide box is arranged on the other side of the clarifying chamber, and the flow guide is from the water phase space after adjustment to the water phase outlet at the front plate of the clarifying chamber; the organic reflux pipe (flow guide pipe) starts from the organic weir bottom plate, is first connected to the top of the bottom plate close to the bottom plate, and then is connected to the reflux port at the front plate of the clarifying chamber along the bottom plate; the overflow box between the mixing chamber and the clarifying chamber is extended to 1 meter, and the mixing chamber is provided with pipe openings of the organic phase, the water phase and the reflux.

[0060] The present application replaces the original design of the pipes at the bottom of the clarifying chamber by adding an inter-stage overflow box or a flow guide pipe or a flow guide box in the mixing chamber and the clarifying chamber; the reflux pipe is arranged inside the clarifying chamber, and the length of the overflow component between the clarifying chamber and the mixing chamber is lengthened to provide space for the front installation of the inter-stage pipes; the above changes can greatly reduce the installation engineering quantity and construction difficulty of the inter-stage pipes, improve the quality of pipe installation, shorten the pipe installation time, and greatly facilitate the maintenance and repair work of the subsequent inter-stage pipes; for the prefabricated extraction equipment for long-distance transportation, the cancellation of the bottom pipe opening can reduce the transportation risk.

[0061] In one feasible embodiment, as Figure 1The second modular connection assembly 32 shown for forming the pipe opening 4 includes a pipe 41 and a flange 42, the pipe 41 is connected with the flange 42 through the pipe opening 4, at least part of the pipe 41 is arranged in the modular mixing chamber 1 or the modular clarification chamber 2; at least part of the flange 42 is located outside the modular mixing chamber 1 or the modular clarification chamber 2.

[0062] The present application connects the mixing chamber and the clarification chamber through the flow box, lengthens the connection between the mixing chamber and the clarification chamber, and adopts the inter-stage connection.

[0063] The prior art connects a large number of pipes at the bottom of the mixing chamber and the clarification chamber, sets the pipe opening from the tail of the bottom plate of the clarification chamber, and connects it to the inlet of the mixing chamber of the next stage and the previous stage. This mode has the following problems: the pipe opening of the bottom plate often conflicts with the support beam on site, resulting in inconvenient installation and temporary changes on site; the pipe is too long from the tail of the pipe connected to the front end of the mixing chamber, and the installation engineering quantity is large; the space at the bottom of the clarification chamber is narrow, and the construction difficulty of workers is large, and the installation quality cannot be guaranteed; the pipe is arranged below the support of the clarification chamber, and the space is very narrow, and it is difficult to enter for repair and maintenance.

[0064] The present application sets the pipe opening of the external inter-stage pipe in the front end of the clarification chamber, and lengthens the flow groove between the mixing chamber and the clarification chamber, simplifies the inter-stage pipe to the front end of the clarification chamber, and reduces the installation quantity of the inter-stage pipe.

[0065] The present application optimizes the inter-stage pipe originally arranged below the support of the clarification chamber to the flow guide box or pipe inside the clarification chamber, and sets the backflow pipe inside the clarification chamber, thereby canceling the inter-stage pipe below the clarification chamber, avoiding the conflict between the pipe opening of the bottom plate of the clarification chamber and the bottom support, reducing the installation engineering quantity of the inter-stage pipe, and avoiding the pipe installation operation of workers in the narrow space below the support, thereby effectively ensuring the pipe installation quality, greatly shortening the pipe installation time, and greatly facilitating the maintenance and repair work of the subsequent inter-stage pipe. Especially for overseas investment projects, this mode can greatly reduce the construction risk of Chinese personnel on site.

[0066] For long-distance transportation of the extraction tank, this mode cancels the bottom pipe opening and changes it to the side wall pipe opening, which to some extent reduces the risk of equipment damage due to bumps and the like during equipment transportation.

[0067] In a feasible embodiment, the modular extraction tank further includes a fine foundation, which is the foundation of the modular mixing chamber 1 and the modular clarification chamber 2.

[0068] The above shows multiple embodiments of the modular extraction tank, but the present application is not limited thereto, for example, the modular clarification chamber can further include a valve and a flow meter for controlling the flow of the organic phase or the aqueous phase of the backflow of the flow guide pipe to the modular mixing chamber.

[0069] Figure 8 is a flowchart of an embodiment of the modular method of the extraction tank of the present application, as Figure 8 The modular method of the extraction tank comprises, as shown in the flowchart of Step S1, preparing a modular mixing chamber; Step S2, preparing a modular clarifying chamber; Step S3, preparing a modular connecting assembly.

[0070] The modular method of the extraction tank of the present application prepares the mixing chamber, the clarifying chamber and the connecting assembly in advance, only positions and installs the mixing chamber and the clarifying chamber on site, then installs the connecting assembly, or directly positions and installs the whole modular extraction tank, then installs the connecting assembly, thereby completing the installation of the extraction tank.

[0071] In an embodiment, step S1 comprises: Step S11, arranging the flow baffle 13, the submerged chamber plate 12 and the cylinder cover 14 on the cylinder body 10; Step S12, conducting a leak test on the modular mixing chamber; Step S13, conducting a water test on the modular mixing chamber; Step S14, reinforcing and protecting the frame of the modular mixing chamber that has passed the water test and the leak test.

[0073] The connecting piece forming the pipe opening 4 can be installed on the cylinder body 10 of the mixing chamber before step S12, or not.

[0074] In an embodiment, steps S12 and S13 comprise: Plugging the pipe opening of the mixing chamber: Injecting water into the mixing chamber and gradually raising the water level to the working water level, setting the time, and observing whether the tank leaks; If the water level drops or there is water around or at the bottom of the tank, it means that the mixing chamber leaks; If the water level is stable and there is no water stain on the periphery and the bottom, it means that the mixing chamber is qualified.

[0075] Since there is no other component on the mixing chamber cylinder 10 except the connecting piece and the mixing chamber cylinder 10 has relatively large strength and is not easy to be damaged, in a feasible embodiment, only a protective frame is arranged on the cylinder cover 14 in step S14, so that the overall and basically intact transportation of the modular mixing chamber can be realized.

[0076] In a feasible embodiment, in step S11, the baffle angle of the adjacent baffles 13 relative to the radial plane of the cylinder 10 is different.

[0077] In a feasible embodiment, step S1 further includes a design step of designing the mixing chamber and the module, and the design includes the size of the mixing chamber, the number of baffles 13, and the baffle angle.
