DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] The purpose of the present utility model is to provide a self-overflow phase separation device to solve the problems existing in the prior art. By using the principle of communicating vessels, automatic liquid separation of two phases is realized, the problem of incomplete phase separation is avoided, and while improving the automation level of the device, the product quality requirements can be well met.
[0023] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] As Figure 1 shown, this embodiment provides a self-overflow phase separation device, which includes a device to be separated 2, a phase separation tank 6, a heavy component receiving tank 12, and a light component receiving tank 13; a feed inlet is provided at the upper part or top of the device to be separated 2, and the feed inlet is used to connect with the upper-stage material pipeline; a discharge valve 3 is provided at the bottom of the device to be separated 2, and the discharge port of the discharge valve 3 is communicated with the middle part of the phase separation tank 6; the bottom of the phase separation tank 6 is communicated with the heavy component receiving tank 12 through a heavy component pipeline, and the upper part of the phase separation tank 6 is communicated with the light component receiving tank 13 through a light component pipeline.
[0025] In this specific embodiment, the feed inlet of the device to be separated 2 is communicated with the outlet end of the feed pump 1, and the feed pump 1 is used to pump the material to be phase-separated in the upper-stage material pipeline into the device to be separated 2.
[0026] The bottom of the device to be separated 2 is higher than the top of the phase separation tank 6. The material enters the device to be separated 2 through the feed pump 1, and after standing in the device to be separated 2, the bottom discharge valve 3 is opened, and the material in the device to be separated 2 flows into the phase separation tank 6 by the potential difference.
[0027] When it is necessary to add material to the device to be separated 2 and the material stands in the device to be separated 2, the discharge valve 3 remains closed, and during the self-shunting process, the discharge valve 3 is in an open state.
[0028] An inlet pipe flowmeter 4 and a regulating valve 5 are provided between the discharge valve 3 and the phase separation tank 6, and the inlet pipe flowmeter 4 and the regulating valve 5 are electrically connected. The inlet pipe flowmeter 4 controls the opening degree of the regulating valve 5 according to the detected flow information.
[0029] An outlet is provided at the bottom and the top of the phase separation tank 6, the bottom outlet is the heavy component outlet, and the top outlet is the light component outlet. A heavy component outlet valve 11 is provided at the heavy component outlet, and a light component outlet valve 7 is provided at the light component outlet. The heavy component outlet valve 11 and the light component outlet valve 7 are kept normally open.
[0030] During the gravity flow process, the gravity flow rate is controlled by the feed pipe flow meter 4 and the regulating valve 5, thereby increasing the standing time of the material in the phase separation tank 6 to avoid overflow of the material from the heavy component outlet or the light component outlet due to too fast feeding.
[0031] A phase separation outlet valve 9 is provided at the bottom of the phase separation tank 6 , and the outlet end of the phase separation outlet valve 9 is connected to one end of the recombination component pipeline, and the other end of the recombination component pipeline is connected to the recombination component receiving tank 12 .
[0032] A recombinant fraction outlet valve 11 is provided at one end of the recombinant fraction pipeline, and the other end of the recombinant fraction pipeline is connected to the top of the recombinant fraction receiving tank 12. The middle part of the recombinant fraction pipeline is located below the light component outlet valve 7, and the distance between the middle part of the recombinant fraction pipeline and the light component outlet valve 7 is determined according to the density of the light component and the heavy component.
[0033] The outlet end of the phase separation outlet valve 9 is also provided with an emulsion layer drain port, and the emulsion layer drain port is provided with an emulsion layer drain valve 10. A glass sight glass 8 is also provided on the phase separation tank 6. When the emulsion layer reaches the light phase outlet, the emulsion layer drain valve 10 is opened to discharge the material in the phase separation tank 6 from the bottom to the emulsion layer tank for the next step of processing.
[0034] The material enters the liquid separation device 2 through the feed pump 1 for static standing. After the static standing is completed, the discharge valve 3 is opened, and the material in the liquid separation device 2 flows into the phase separation tank 6 by gravity. The first material to enter the phase separation tank 6 is the heavy component, which flows into the heavy component receiving tank 12 by gravity through the outlet pipe below the phase separation tank 6. After the light component enters the phase separation tank 6, due to the density difference between the heavy component and the light component, when the liquid level in the heavy component receiving tank 12 reaches the same level as the heavy component outlet pipe at the bottom of the phase separation tank 6, the heavy component can no longer flow out from the bottom outlet pipe of the phase separation tank 6 until the liquid level continues to rise to the top outlet, and the light component flows into the light component receiving tank 13 by gravity, thereby realizing two-phase separation, and the process does not require manual operation.
[0035] After the liquid level switch at the bottom of the liquid separation equipment 2 detects that there is no liquid level in the kettle, the bottom discharge valve 3 is automatically closed, and the feed pump 1 of the liquid separation equipment 2 is interlocked to transfer the material and carry out the next batch operation.
[0036] The material transfer pumps of the light component receiving tank and the heavy component receiving tank 12 are interlocked with the liquid level. When the liquid level in the light component receiving tank or the heavy component receiving tank 12 reaches a certain height, the pump is automatically started to transfer the material, and the pump is stopped when the liquid level reaches the lower limit.
[0037] The entire process of liquid separation is automated and requires no human intervention.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
