[0051] In the related technology, the oil-water separation device is mainly used to efficiently separate the mixture of oil and water, and is widely used in many fields such as oil extraction, shipping, chemical industry, sewage treatment, food processing, environmental protection, etc. Most common oil-water separation devices use gravity separation, which is also the most basic oil-water separation method, using the density difference between oil and water, oil floats on top and water sinks.

[0052] In the field of battery production technology, hydrogen peroxide and oil-liquid mixtures are mostly separated by oil-water separation devices, which are mostly composed of three oil separators placed at a certain distance in a pool. After the mixture of oil and hydrogen peroxide enters the oil-water separation device, the oil and water are separated due to the low density of the oil and the high density of the hydrogen peroxide solution. The oil flows from the upper layer of the oil separator to the oil recovery pool, and the hydrogen peroxide flows from the bottom of the oil separator to the hydrogen peroxide recovery pool. However, the separation effect of this oil-water separation device is poor, and the content of hydrogen peroxide in the separated oil is high.

[0053] like Figure 1As shown, in order to solve the above technical problems, an embodiment of the present application provides a separation device, which includes a container assembly 100, a first extraction assembly 200 and a switching assembly 300. The container assembly 100 has a first inlet end 160, a first outlet end 170 and N cavities 110. The N cavities 110 are arranged in sequence from the first inlet end 160 to the first outlet end 170, and satisfy: N is a positive integer, and N ≥ 2; wherein the bottoms of adjacent cavities 110 are connected, the first cavity 110 is connected to the first inlet end 160, and the Nth cavity 110 is connected to the first outlet end 170. 0; the first pumping assembly 200 has a second inlet end 210 and a second outlet end 220, the second outlet end 220 is connected to the first cavity 110, and the second inlet end 210 is connected to the Nth cavity 110, and the first pumping assembly 200 can drive the liquid located at the second inlet end 210 to flow to the second outlet end 220; the switching assembly 300 is respectively connected to the first outlet end 170 and the second inlet end 210, and the switching assembly 300 can at least switch the Nth cavity 110 between a first state connected to the first outlet end 170 and a second state connected to the second inlet end 210.

[0054] In this embodiment, the container assembly 100 is a core component, and is designed as a series of interconnected cavities 110. The number of cavities 110 is N, where N ≥ 2 and is a positive integer. These cavities 110 are arranged in sequence from the first inlet port 160 to the first outlet port 170, and the bottoms of adjacent cavities 110 are connected to ensure that the mixed liquid of oil and hydrogen peroxide can flow through all cavities 110 in sequence; in other words, multiple cavities 110 are arranged in sequence on the flow path of the mixed liquid. Specifically, the positions of the first inlet port 160 and the first outlet port 170 are set to plan and limit the flow path of the mixed liquid. During operation, the mixed liquid flows into the first cavity 110 from the first inlet port 160, and then is discharged from the first outlet port 170 after passing through all cavities 110, thereby ensuring the import and output paths of the mixed liquid.

[0055] It should be noted that after the mixed liquid enters the cavity 110, due to the density difference, the oil and hydrogen peroxide are separated into layers, with the oil located in the upper layer and the hydrogen peroxide located in the lower layer. Therefore, the bottoms of adjacent cavities 110 are connected to each other so that the hydrogen peroxide can flow from the lower end of the cavity 110 into the next cavity 110, while the oil will remain in the upper end of the cavity 110. Obviously, multiple separations through multiple cavities 110 can improve the separation effect and have higher separation efficiency.

[0056] For example, a suction pipe or opening is provided at the upper end of the cavity 110 to ensure that the oil at the upper end of the cavity 110 can be extracted. Compared with the content of hydrogen peroxide, the content of oil in the mixed liquid is lower, so there is no need to continuously extract the oil.

[0057] Of course, since most of the oil is separated and retained in the first cavity 110, the capacity of the first cavity 110 can be set larger than the capacity of the remaining cavities 110. For example, the first cavity 110 can be set to 2 times, 3 times, 4 times, 5 times, etc. the capacity of the remaining cavities 110.

[0058] In this embodiment, the first pumping assembly 200 is responsible for driving the liquid flow. The second inlet end 210 and the second outlet end 220 of the first pumping assembly 200 are respectively connected to the first cavity 110 and the Nth cavity 110 of the container assembly 100. Through this assembly, the liquid can be pushed from the second inlet end 210 to the second outlet end 220 to achieve directional flow control of the liquid in the system. Obviously, the first pumping assembly 200 can form a circulation loop with the container assembly 100 to repeatedly separate the mixed liquid, ensure that the oil content in the hydrogen peroxide discharged from the first outlet end 170 meets the standard, and reduce the waste of oil.

[0059] In this embodiment, the switching component 300 connects the first outlet port 170 and the second inlet port 210, and can change the flow state of the N chambers 110 through the switching operation. If the oil content in the hydrogen peroxide in the Nth chamber 110 meets the standard, when switching to the first state, the separated hydrogen peroxide is directly discharged from the first outlet port 170, and the oil content in the hydrogen peroxide meets the standard; if the oil content in the hydrogen peroxide in the Nth chamber 110 does not meet the standard, when switching to the second state, the separated hydrogen peroxide enters the second inlet port 210, and is re-discharged into the first chamber 110 through the first pumping component 200, so that the hydrogen peroxide is re-separated to reduce the oil content in the hydrogen peroxide.

[0060] Obviously, this design enables the separation device to dynamically adjust the processing flow according to the needs to adapt to different separation or circulation requirements. This separation device, through a highly integrated design, not only realizes the introduction, processing and output of liquids, but also has the ability to flexibly switch internal processes to adapt to different separation requirements. It is suitable for industries and water treatment that require efficient liquid processing and separation.

[0061] By using the separation device provided by the present application, the Nth cavity 110 connected to the first outlet port 170 is connected to the first cavity 110 through the first pumping assembly 200. When the oil content in the liquid in the Nth cavity 110 exceeds the standard, the switching assembly 300 is controlled to switch the Nth cavity 110 to the first state. At this time, the Nth cavity 110 is connected to the first cavity 110 through the first pumping assembly 200, and then the liquid in the Nth cavity 110 is re-pumped into the first cavity 110 through the first pumping assembly 200 for re-separation and filtration; and by setting N cavities 110, multi-stage separation can be achieved, thereby improving the separation accuracy of the oil-water mixture to reduce the oil content in the hydrogen peroxide after separation; and since the oil is temporarily stored at the upper end of the cavity 110, it is beneficial to separate the oil and hydrogen peroxide, thereby reducing the hydrogen peroxide content in the separated oil.

[0062] like Figure 1 As shown, in some embodiments, the container assembly 100 includes a container member 180 and a partition 120, the container member 180 has an inner cavity, and the first inlet end 160 and the first outlet end 170 are respectively connected to the inner cavity; the partition 120 and the container member 180 are connected, the partition 120 is located in the inner cavity, and the partition 120 can divide the inner cavity into N cavities 110 in the direction from the first inlet end 160 to the first outlet end 170; wherein, the partition 120 has a channel 122 at one end close to the bottom of the inner cavity, and the channel 122 can connect the bottoms of adjacent cavities 110.

[0063] In this embodiment, the container part 180 serves as a main body and has a continuous space, i.e., an inner cavity. The two ends of the container part 180 are respectively connected to the first inlet end 160 and the first outlet end 170. The first inlet end 160 and the first outlet end 170 are respectively connected to the inner cavity, and the two are directly connected and open to the inner cavity, ensuring smooth entry and discharge of the fluid.

[0064] The partition 120 is placed inside the container 180, and can be moved or fixed in position, and adjusted as needed to achieve subdivision of the cavity 110. In other words, the partition 120 flexibly divides the inner cavity into N independent intervals along the direction from the first inlet end 160 to the first outlet end 170, where N is a positive integer ≥ 2, to meet different processing requirements. Among them, the bottoms of adjacent cavities 110 are connected; illustratively, the partition 120 is designed with channels 122 near the bottom of the cavity 110, and these channels 122 are connected to the bottom of the adjacent cavities 110, ensuring that even if the partition is not completely isolated, the bottom fluid can still be connected, which is conducive to fluid exchange.

[0065] Obviously, this container assembly 100 with equal emphasis on design flexibility and efficiency not only meets the requirements of multi-stage separation and processing, but also can adjust the number of cavities 110 according to specific working conditions to optimize the separation effect.

[0066] Exemplarily, there are multiple separators 120, and the separators 120 are separators, and a hole 122 is set at one end of the separator close to the bottom of the inner cavity. The separators are arranged at intervals in the flow direction, and the two ends of the separators are respectively connected and fixed to the side walls of the inner cavity.

[0067] Optionally, the container 180 is configured as a metal box, the partition is configured as a metal plate, and the partition is welded and fixed to the container 180. Of course, in other embodiments, the container 180 can also be configured as a stacked pool body, and the partition can be stacked in the pool body, etc., which is not specifically limited here.

[0068] like Figure 1 As shown, in some embodiments, the cavity 110 is set as a sealed structure to reduce external pollution. On this basis, a pressure relief pipe 130 can be added to the container 180 to connect the inner cavity with the outside through the pressure relief pipe 130. Optionally, the container 180 can also be provided with an observation window 140 to facilitate observation of the internal working conditions.

[0069] like Figure 1 As shown, in some embodiments, the separation device further includes a second pumping assembly 400, at least the first cavity 110 among all the cavities 110 is connected to the second pumping assembly 400, the second pumping assembly 400 has a third inlet end 410 and a third outlet end 420, the third inlet end 410 is located in the first cavity 110, and the third inlet end 410 is higher than the channel 122, the third outlet end 420 is located outside the first cavity 110, and the second pumping assembly 400 drives the liquid located at the third inlet end 410 to flow to the third outlet end 420.

[0070] In this embodiment, the separation device further adds a second pumping assembly 400 to enhance its operational flexibility and controllability. The second pumping assembly 400 focuses on the operation of at least the first chamber 110 or more chambers 110 to extract the oil in the upper layer of the chamber 110 at a fixed time.

[0071] The present application takes the second pumping assembly 400 provided in the first cavity 110 as an example. The second pumping assembly 400 has a third inlet 410, which is arranged in the first cavity 110, and the position of the third outlet 420 is designed to be higher than the channel 122, which means that it can absorb the liquid above, that is, the oil in the upper layer, and avoid sucking the hydrogen peroxide in the lower layer. The third outlet 420 is located outside the cavity 110, and cooperates with the second pumping assembly 400 to drive the liquid located at the third inlet 410 to flow to the third outlet 420, so as to facilitate the extraction of the oil for recycling.

[0072] For example, the oil in the cavity 110 can also be drained by using a draining device in conjunction with a pipeline. Alternatively, the oil can be drained manually by using a container.

[0073] like Figure 1 As shown, in some embodiments, the first pumping assembly 200 includes a first pumping member 230, and the first pumping member 230, the second inlet port 210 and the second outlet port 220 are connected in series, and the first pumping member 230 can pump the liquid in the Nth cavity 110; wherein the first outlet port 170 and the second inlet port 210 are respectively connected to the Nth cavity 110 through the first pumping member 230.

[0074] In this embodiment, the first outlet port 170 and the second inlet port 210 can share a first pumping member 230 through structural arrangement; that is, if the Nth cavity 110 is connected to the first outlet port 170, the first pumping member 230 can accelerate the discharge of the liquid in the Nth cavity 110. If the Nth cavity 110 is connected to the second inlet port 210, the first pumping member 230 pumps the liquid in the Nth cavity 110 into the first cavity 110 to separate the liquid again.

[0075] For example, the first pumping and exhausting member 230 is a diaphragm pump. Of course, in other embodiments, the first pumping and exhausting member 230 may also be a centrifugal pump, a piston pump, a jet fluid pump, etc., which are not specifically limited here.

[0076] like Figure 1 As shown, in some embodiments, the second pumping assembly 400 includes a second pumping member 430 , a third inlet port 410 , the second pumping member 430 and a third outlet port 420 are connected in series, and the second pumping member 430 can pump the liquid in the first cavity 110 .

[0077] Similarly, the second pumping member 430 is periodically activated to discharge the oil in the first chamber 110 . The type of the second pumping member 430 is not specifically limited, as long as it has a pumping function.

[0078] For example, the second pumping and exhausting member 430 is a diaphragm pump. Of course, in other embodiments, the second pumping and exhausting member 430 may also be a centrifugal pump, a piston pump, a jet fluid pump, etc., which are not specifically limited here.

[0079] like Figure 1 As shown, in some embodiments, the switching assembly 300 includes a first valve component 310, a second valve component 330 and a detection component 320, the first pumping component 230 is respectively connected to the first outlet port 170 and the second inlet port 210 through the first valve component 310; the first inlet port 160 is connected to the first cavity 110 through the second valve component 330; the detection component 320 is connected to the first outlet port 170, and the detection component 320 can detect the oil content of the liquid in the first outlet port 170.

[0080] In this embodiment, the first valve member 310 controls the communication between the first pumping assembly 200 and the first outlet port 170 and the second inlet port 210 , and the pumping and delivery operation of the second pumping assembly 400 between different cavities 110 is realized by switching the first valve member 310 .

[0081] The second valve member 330 is disposed at the first inlet end 160 and is directly connected to the first cavity 110. This design is used to control the direct liquid passage between the first inlet end 160 and the first cavity 110. The first inlet end 160 is used to discharge liquid into the first cavity 110. The second valve member 330 can adjust the flow rate of the first inlet end 160 to cooperate with the first pumping assembly 200 to pump the liquid in the Nth cavity 110 into the first cavity 110, thereby playing a role in balancing the flow rate.

[0082] Among them, the detection element 320 can detect the oil and water content in the liquid in the Nth cavity 110, which is a key intelligent element. It is monitored in real time through sensors or detection technology, involving optical, electrical conductivity, capacitance or physical sensing, to ensure that the separation process is carried out as needed and avoid the extraction of substandard liquid.

[0083] In summary, this design achieves flexible liquid flow control through the ingenious layout of the first valve component 310 and the second valve component 330, and the introduction of the detection component 320 makes it more adaptable and dynamically adjusts the operation according to the liquid content in the cavity 110, thereby improving the separation efficiency and accuracy.

[0084] Exemplarily, the detection element 320 is configured as an oil-in-water analyzer; of course, in other embodiments, it can also be configured as a capacitive sensor, an ion selective electrode, a thermal conductive fluid sensor, etc., which is not specifically limited here.

[0085] For example, the first valve component 310 can be configured as a switch valve, a regulating valve, a flow valve, etc. Similarly, the second valve component 330 can be configured as a switch valve, a regulating valve, a flow valve, etc.

[0086] In this embodiment, the first valve component 310 includes a valve A311 and a valve B312. The first outlet port 170 is connected to the first pumping and exhausting component 230 through the valve A311, and the second inlet port 210 is connected to the first pumping and exhausting component 230 through the valve B312. That is, the connection state between the Nth chamber 110 and the first outlet port 170 and the second inlet port 210 is switched by controlling the valve A311 and the valve B312 respectively.

[0087] Exemplarily, valve A 311 is opened and valve B 312 is closed, and the Nth cavity 110 is in the first state; valve A 311 is closed and valve B 312 is opened, and the Nth cavity 110 is in the second state.

[0088] Of course, in other implementations, the first outlet port 170 and the second inlet port 210 may also be connected to the first pumping and exhausting member 230 via a three-way valve, so that the communication state can be switched by controlling the three-way valve.

[0089] like Figure 1 As shown, in some embodiments, the switching assembly 300 further includes a controller, which is electrically connected to the detection component 320, the first valve component 310, and the second valve component 330 respectively.

[0090] That is, the controller is used to receive the detection data of the detection component 320, and process and compare the detection data. When the detected oil content is greater than the set threshold, the controller sends a control instruction to the first valve component 310 and the second valve component 330 to connect the Nth cavity 110 with the second inlet end 210, close the first outlet end 170, close the second valve component 330 or reduce the opening of the second valve component 330, so that the liquid in the Nth cavity 110 flows back to the first cavity 110. It should be noted that this part adopts the basic control logic method of the controller, the input, processing and output of the signal, and there is no method improvement.

[0091] Exemplarily, the controller is configured as a PLC programmable controller; of course, in other embodiments, the controller may also be configured as a microprocessor, a remote terminal unit, a distributed I / O system, an intelligent controller, and the like.

[0092] like Figure 2 As shown, in some embodiments, the container assembly 100 also includes a corrugated plate interceptor 150, the corrugated plate interceptor 150 has a fourth outlet port 151 and a fourth inlet port 153, in the flow direction of the liquid, the upstream side of the partition 120 is a water-facing surface 121, the fourth inlet port 153 is located upstream of the fourth outlet port 151, the fourth outlet port 151 is connected to the water-facing surface 121, the fourth outlet port 151 forms a covering area on the water-facing surface 121, and the channel 122 is located within the covering area.

[0093] In these embodiments, the container assembly 100 further integrates a corrugated plate interceptor 150 to enhance the oil-water separation effect and fluid management. The corrugated plate interceptor 150 is added to the container assembly 100 and has a fourth inlet port 153 and a fourth outlet port 151, which is intended to optimize the liquid flow path and improve the processing efficiency. The interceptor increases the surface area through its unique corrugated design, optimizes the contact between the liquid and the corrugated plate 1522, and promotes oil-water separation.

[0094] In addition, the fourth outlet port 151 may also cover the entire water-facing surface 121. By increasing the contact area between the corrugated plate interceptor 150 and the liquid, it is helpful to promote oil-water separation.

[0095] The partition 120 is located downstream of the corrugated plate interceptor 150, and the corrugated plate interceptor 150 performs preliminary treatment to separate the oil-free water, and only after passing through the corrugated plate interceptor 150 can it flow into the next chamber 110. The fourth inlet port 153 is located upstream of the fourth outlet port 151, ensuring that the liquid is fully treated by the corrugated plate 1522 before flowing to the fourth outlet port 151, and the fourth outlet port 151 is directly connected to the water surface, ensuring the smooth flow of the liquid.

[0096] A covering area is formed on the water-facing surface 121 of the corrugated plate interceptor 150, and the pores 122 are located in the covering area, which also ensures that the liquid can enter the pores 122 only after passing through the corrugated plate interceptor 150, thereby ensuring that the oil-water separation is fully promoted, the oil droplet aggregation and the purity of the hydrogen peroxide are improved.

[0097] Obviously, the addition of the corrugated plate interceptor 150 in the container assembly 100, through its unique design, not only increases the surface area, but also optimizes the fluid dynamics. Combined with the pre-treatment of the separator 120, a more efficient and refined oil-water separation process is achieved, which is particularly suitable for environments requiring high-precision separation, processing volume or complex liquids.

[0098] Exemplarily, the corrugated plate 1522 of the corrugated plate interceptor 150 is horizontally arranged, and the corrugations of the corrugated plate 1522 are extended along the extension direction of the channel 122 .

[0099] like Figure 2 and Figure 3 As shown, in some embodiments, the corrugated plate interceptor 150 includes an interception module 152 and a shell 154, the interception module 152 has a plurality of corrugated plate flow channels 1523; the shell 154 is connected to the partition 120, the shell 154 is respectively connected to the fourth outlet port 151 and the fourth inlet port 153, the shell 154 has a cavity 1541, the interception module 152 is located in the cavity 1541, the fourth outlet port 151 is connected to the fourth inlet port 153 through the corrugated plate flow channel 1523; wherein the opening size of the fourth inlet port 153 is configured to enable the interception module 152 to enter and exit the cavity 1541.

[0100] That is, the hole 122 is connected to the corresponding cavity 110 through the cavity 1541 , the interception module 152 is located in the cavity 1541 , and the opening size of the fourth inlet end 153 is configured to enable the interception module 152 to enter and exit the cavity 1541 .

[0101] In these embodiments, the design of the corrugated plate interceptor 150 is further refined, and an interception module 152 and a cavity 1541 are introduced, which improves the flexibility and efficiency of fluid processing. The corrugated plate interceptor 150 is embedded with an interception module 152, and each interception module 152 module contains a plurality of corrugated plate channels 1523, which increases the modularity of the structure, facilitates maintenance, replacement or upgrading, and optimizes different processing requirements.

[0102] Both ends of each corrugated plate flow channel 1523 are directly connected to the fourth inlet end 153 and the fourth outlet end 151 to form a continuous fluid channel, thereby promoting efficient flow of liquid between the corrugated plates 1522 and separating oil and water by using the corrugation effect.

[0103] The water-facing surface 121 cooperates with the cavity 1541, and the hole 122 is connected to the cavity 1541 to maintain the flow of liquid and improve the oil-water separation efficiency. It should be noted that the opening size of the fourth inlet end 153 is just enough to allow the interception module 152 to enter and exit the cavity 1541, which means that the interception module 152 can be moved, replaced or adjusted to adapt to different fluid characteristics, or cleaned to improve the separation effect.

[0104] Exemplarily, the shell 154 includes a pair of limiting plates, which are arranged in parallel and respectively located at the upper end and the lower end of the channel 122 , and then the pair of limiting plates and the inner wall of the cavity 110 are surrounded to form the shell 154 .

[0105] like Figure 7 and Figure 8 As shown, in some embodiments, the interception module 152 includes a plurality of corrugated plates 1522 , which are stacked in the cavity 1541 , and a corrugated plate flow channel 1523 is formed between adjacent corrugated plates 1522 .

[0106] Exemplarily, the inner cavity of the cavity 1541 is configured to be square, and a plurality of corrugated plates 1522 are stacked in sequence from bottom to top in the cavity 1541, so as to facilitate the removal and placement of the corrugated plates 1522 during subsequent maintenance.

[0107] Exemplarily, the water-facing surface 121 is provided with a pair of fixing plates, and the pair of fixing plates are respectively arranged at the upper end and the lower end of the channel 122, and then the pair of fixing plates and the side walls of the cavity 110 are surrounded to form the cavity 1541.

[0108] In order to ensure that the interception module 152 is stably placed in the cavity 1541 , the circumferential side wall of the interception module 152 and the inner wall of the cavity 1541 are arranged to abut against each other.

[0109] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the interception module 152 includes a plurality of corrugated plates 1522 and a connecting portion 1521. The plurality of corrugated plates 1522 are arranged in a stacked manner, and a corrugated plate flow channel 1523 is formed between adjacent corrugated plates 1522. The connecting portion 1521 has a card slot 15211, and the card slot 15211 extends along the stacking direction of the corrugated plates 1522. The end of the corrugated plate 1522 is located in the card slot 15211 on the corresponding side.

[0110] That is, by setting the connecting portion 1521 to clamp all the corrugated plates 1522, it is convenient to quickly remove or place multiple corrugated plates 1522 from the cavity 1541. At the same time, since all the corrugated plates 1522 are clamped to the connecting portion 1521, it is convenient to separate the corrugated plates 1522 and the connecting portion 1521.

[0111] Exemplarily, the connecting portion 1521 includes a pair of snap-fit ​​blocks, each of which is provided with a snap-fit ​​groove 15211 , so that the pair of snap-fit ​​blocks can be snap-fitted to two sides of the corrugated plate 1522 , respectively.

[0112] Illustratively, the corrugated plates 1522 are stacked in an offset manner, so that corrugated plate channels 1523 can be formed between adjacent corrugated plates 1522 .

[0113] In some embodiments, the first inlet port 160 is connected to the opening of the side wall of the first cavity 110 , and a baffle 190 is disposed in the first cavity 110 , and the baffle 190 is used to guide the liquid flowing into the opening to the bottom of the first cavity 110 .

[0114] In addition, to facilitate understanding of the technical solution of this application, the working principle is provided as follows:

[0115] After the mixed liquid to be separated enters the container 180 from the first inlet port 160, it flows through all the cavities 110 in sequence, so that the oil and hydrogen peroxide in the mixed liquid are separated in the cavity 110, the oil remains in the cavity 110, and the separated hydrogen peroxide is discharged through the first outlet port 170; when the detection component 320 detects that the oil content in the hydrogen peroxide in the Nth cavity 110 does not meet the standard, the hydrogen peroxide in the Nth cavity 110 is re-discharged into the first cavity 110 through the first pumping assembly 200 for re-or multiple separation, thereby improving the separation effect.

[0116] In some embodiments, the present application also provides a recovery system, which includes the separation device described in any of the above embodiments.

[0117] Since the above-mentioned separation device has the above-mentioned technical effects, the recovery system including the separation device should have the same technical effects, which will not be repeated here.
