[0046] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0048] The oil depot oil dumping control system and method of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0049] See also Figure 1 and Figure 2 As shown, the present application provides an oil depot oil pouring control system, including: an oil outlet valve 6, an oil inlet valve 8, a flow regulating valve 13, an oil pouring pipeline 15 and a controller 16. The oil outlet valve 6 is arranged at the oil outlet of the first tank body 1 (also known as the pouring tank). The oil inlet valve 8 is arranged at the oil inlet of the second tank body 2 (also known as the pouring tank). The oil pouring pipeline 15 is connected between the oil outlet valve 6 and the oil inlet valve 8. The flow regulating valve 13 is arranged on the oil pouring pipeline 15. The controller 16 is electrically connected to the oil outlet valve 6, the oil inlet valve 8 and the flow regulating valve 13. The controller 16 is configured to determine the oil pouring flow rate of the oil material according to the liquid level difference between one of the first tank body 1 and the second tank body 2, and adjust the opening value of the flow regulating valve 13 according to the oil pouring flow rate.

[0050] In the oil depot oil pouring control system of the present application, the controller 16 can adjust the opening value of the flow regulating valve 13 according to the oil pouring flow rate of the oil, so as to adjust the oil pouring flow rate of the oil to a specified range. It reduces the problem of too long operation time due to too low flow rate, which affects the work efficiency. Or due to too high flow rate, a large amount of static charge is generated in the oil pipeline and the oil tank, causing safety hazards, and causing impact on the inner float of the tank.

[0051] In some optional embodiments, the oil pouring pipeline 15 includes an oil delivery pipeline 11 and an oil receiving pipeline 12, the oil delivery pipeline 11 is connected to the oil delivery valve 6, and the oil receiving pipeline 12 is connected to the downstream end of the oil delivery pipeline 11 and is connected to the oil inlet valve 8. The flow regulating valve 13 is arranged between the oil delivery pipeline 11 and the oil receiving pipeline 12. Optionally, the flow regulating valve 13 is arranged on the oil delivery pipeline 11, which can be understood as an oil delivery pipeline valve. Optionally, the oil receiving pipeline 12 is also provided with an oil receiving pipeline valve 14, and either the oil delivery pipeline valve or the oil receiving pipeline valve 14 can be selected as the flow regulating valve.

[0052] like Figure 2 As shown, the oil depot oil pouring control system can also include: a pouring tank inlet root valve 3, a pouring tank inlet second valve 4, a pouring tank outlet tank root valve 5, a pouring tank inlet root valve 7, a pouring tank outlet tank root valve 9 and a pouring tank outlet second valve 10.

[0053] Among them, the pouring tank outlet tank root valve 5 is arranged between the oil outlet valve 6 and the oil outlet of the first tank body 1, and the oil outlet valve 6 can be understood as the second valve of the pouring tank outlet. The pouring tank inlet tank root valve 3 is arranged at the oil inlet of the first tank body 1, and the pouring tank inlet second valve 4 is connected to the pouring tank inlet tank root valve 3 and connected to the oil collection pipeline 12. It can be understood that the pouring tank inlet tank root valve 3 is a valve arranged at the bottom of the first tank body 1, which is used to clean and control the flow of oil in the first tank body 1. It can prevent the oil in the oil tank from being completely discharged during cleaning, and can also control the flow of oil when necessary. Therefore, it plays a vital role in the oil storage tank.

[0054] The main function of the second valve 4 at the pouring tank inlet is to control the flow of materials and prevent leakage. In this way, the tank root valve 3 at the pouring tank inlet and the second valve 4 at the pouring tank inlet form a double valve to ensure that even if the tank root valve 3 (main valve) at the pouring tank inlet fails or is damaged, the second seal of the second valve 4 at the pouring tank inlet can still effectively prevent material leakage. It can also prevent pollution. The materials in the storage tank sometimes cross-contaminate with the outside world. After adopting the double valve design, even if the main valve fails or is improperly opened, the second seal (the second valve 4 at the pouring tank inlet) can still prevent the materials from being contaminated by the outside world.

[0055] The pouring tank inlet tank root valve 7 is arranged between the oil inlet valve 8 and the oil inlet of the second tank body 2. The oil inlet valve 8 can be understood as the pouring tank inlet second valve. The pouring tank outlet tank root valve 9 is arranged at the oil outlet of the second tank body 2. The pouring tank outlet second valve 10 is connected to the pouring tank outlet tank root valve 9 and is connected to the oil delivery pipeline 11. The pouring tank outlet tank root valve 9 and the pouring tank outlet second valve 10 are similar to the pouring tank inlet tank root valve 3 and the pouring tank inlet second valve 4, forming a double valve. The function is also the same as the pouring tank inlet tank root valve 3 and the pouring tank inlet second valve 4.

[0056] It can be understood that the tank root valve 3 at the outlet of the tank, the tank root valve 5 at the outlet of the tank, the tank root valve 7 at the inlet of the tank, and the tank root valve 9 at the outlet of the tank are the inlet / outlet tank root valves of the oil tank. Under normal circumstances, the tank root valves are in a normally open state. The second valve 4 at the inlet of the tank, the oil outlet valve 6, the oil inlet valve 8, and the second valve 10 at the outlet of the tank are the second valves at the inlet / outlet, which are usually in a closed state. Only when the oil tank is filled with oil, the second valve at the inlet is opened (while the second valve at the outlet is kept closed), and conversely, when the oil tank is discharged from oil, the second valve at the outlet is opened (while the second valve at the inlet is kept closed).

[0057] In some optional embodiments, the oil depot oil pouring control system further includes a first liquid level sensor 17, which is disposed in the first tank body 1 and electrically connected to the controller 16, and is used to measure the liquid level value in the first tank body 1. The oil depot oil pouring control system further includes a second liquid level sensor 18, which is disposed in the second tank body 2 and electrically connected to the controller 16, and is used to measure the liquid level value in the second tank body 2.

[0058] In some optional embodiments, the controller 16 is configured to determine the magnitude of the pouring oil flow rate and the target flow rate, and adjust the opening value of the flow regulating valve 13 according to the determination result. When the pouring oil flow rate is lower than the target flow rate, the opening value of the flow regulating valve 13 is increased. When the pouring oil flow rate is greater than the target flow rate, the opening value of the flow regulating valve 13 is decreased.

[0059] The opening k of the flow control valve, the liquid level difference h of the pouring tank / pouring tank (i.e. the first tank body / the second tank body), and the diameter d of the oil pouring pipeline are three factors that affect the pouring flow rate v of the oil in the oil pouring pipeline; v is negatively correlated with d, and positively correlated with k and h. That is, the larger the diameter d of the oil pouring pipeline, the smaller the pouring flow rate v of the oil. The larger the opening k of the flow control valve, the larger the pouring flow rate v of the oil. Then, in practical applications, it can be calculated by formula (1) (Δh * S) / (Δ t* S1)Calculate the oil pouring flow rate, where Δh is the level difference between the pouring tank and the pouring tank within the time period Δt. S is the cross-sectional area of ​​the pouring tank and the pouring tank. S1 is the cross-sectional area of ​​the pouring pipeline, which can be calculated by formula (2)πd 2 / 4 is calculated, and d is the diameter of the oil pouring pipeline. In this way, the calculated oil pouring flow rate is compared with the specified target flow rate. If it is lower than the target flow rate, the opening of the flow control valve is increased. Otherwise, the opening of the flow control valve is reduced until the oil pouring flow rate is adjusted to the specified target flow rate.

[0060] In some optional embodiments, the controller 16 is configured to adjust the opening value of the flow regulating valve 13 to an opening value corresponding to the current liquid level difference of the first tank body 1 and the current oil pouring flow rate of the oil according to a correspondence table among the liquid level difference of the first tank body 1, the oil pouring flow rate of the oil and the opening value of the flow regulating valve 13.

[0061] After repeated experiments, the historical data, i.e., the oil flow rate v, the level difference h of the pouring / pouring tank, and the opening k of the flow control valve, can be recorded in advance to fit the function v=f(h,k). In the actual oil pouring operation, the level difference h and the required oil flow rate v are substituted into the function to calculate the approximate range of the opening k of the flow control valve. Alternatively, the historical data can be organized into a corresponding relationship table. In the actual oil pouring operation, after obtaining the level difference h and the required oil flow rate v, the opening k of the flow control valve can be obtained by looking up the table, so that the flow rate can be adjusted to the specified value more quickly.

[0062] In the actual application of oil pouring operation, the pouring tank inlet root valve 3, the pouring tank inlet root valve 7, the pouring tank outlet tank root valve 9, the oil outlet valve 6 and the oil inlet valve 8 are in the open state, the pouring tank inlet second valve 4 and the pouring tank outlet second valve 10 are in the closed state, the oil delivery pipeline valve is selected as the flow regulating valve, and the oil receiving pipeline valve 14 is in the open state. Figure 2 The arrow in the middle indicates the direction of oil flow when pouring oil. When pouring oil into an empty tank, the opening of the flow regulating valve 13 is slowly increased at the beginning to control the pouring flow rate of the oil. For example, the flow rate is first controlled within 1m / s, and after the oil has submerged the inlet of the pouring tank, the flow rate is adjusted to about 4.5m / s.

[0063] The first liquid level sensor 17 detects the change of the liquid level in the first tank body 1. The second liquid level sensor 18 detects the change of the liquid level in the second tank body 2. The controller 16 calculates the current oil pouring flow rate of the oil material according to the change of the liquid level in the first tank body 1 or the second tank body 2, and then compares the current oil pouring speed of the oil material with the target flow rate. When the oil pouring flow rate is lower than the target flow rate, the opening value of the flow regulating valve 13 is increased. When the oil pouring flow rate is greater than the target flow rate, the opening value of the flow regulating valve 13 is reduced. Or directly by looking up the table, the opening value of the flow regulating valve 13 is adjusted to the opening value corresponding to the current liquid level difference of the first tank body 1 and the current oil pouring flow rate of the oil material.

[0064] It should be noted that when the controller fails, the above process can also be completed by two staff members. The B-post staff slowly adjusts the opening of the flow control valve at the oil tank area, and the A-post staff calculates the oil pouring flow rate based on the liquid level difference obtained by the liquid level sensor and the oil pouring pipeline diameter. The A-post and the B-post staff exchange information and adjust the opening of the flow control valve to adjust the oil pouring flow rate to the target flow rate within the specified range.

[0065] See also Figure 3 As shown, the present application also provides an oil depot oil pouring control method, including: steps S1-S4:

[0066] Step S1: Open the oil outlet valve 6, the oil inlet valve 8 and the flow regulating valve 13;

[0067] Step S2: determining a liquid level difference between the first tank body 1 and the second tank body 2;

[0068] Step S3: determining the oil pouring flow rate of the oil material according to the liquid level difference;

[0069] Step S4: According to the oil pouring flow rate, adjusting the opening value of the flow regulating valve 13 so that the oil pouring flow rate reaches the target flow rate.

[0070] The oil depot oil pouring control method of the present application can adjust the opening value of the flow regulating valve 13 according to the oil pouring flow rate of the oil, so as to adjust the oil pouring flow rate of the oil to a specified range. It reduces the problem of too long operation time due to too low flow rate, which affects the work efficiency. Or due to too high flow rate, a large amount of static charge is generated in the oil pipeline and the oil tank, causing safety hazards, and causing impact on the inner float of the tank.

[0071] In some optional embodiments, determining the liquid level difference between one of the first tank body 1 and the second tank body 2 includes:

[0072] The first tank body 1 is provided with a first liquid level sensor 17, and a first liquid level difference in the first tank body 1 is determined by the first liquid level sensor 17. The second tank body 2 is provided with a second liquid level sensor 18, and a second liquid level difference in the second tank body 2 is determined by the second liquid level sensor 18.

[0073] In some optional implementations, determining the oil pouring flow rate of the oil material according to the liquid level difference can be achieved in any of the following ways. Specifically including:

[0074] (1) Obtaining a first liquid level difference Δh in the first tank body 1 within a set time length Δt; determining a first flow rate of the first tank body 1 according to the product of the first liquid level difference and the cross-sectional area of ​​the first tank body 1; and determining the pouring flow rate of the oil according to the quotient of the first flow rate and the cross-sectional area of ​​the oil pouring pipeline 15.

[0075] (2) Obtaining a second liquid level difference Δh in the second tank body 2 within a set time length Δt; determining a second flow rate of the second tank body 2 according to the product of the second liquid level change and the cross-sectional area of ​​the second tank body 2; and determining the pouring flow rate of the oil according to the quotient of the second flow rate and the cross-sectional area of ​​the oil pouring pipeline 15.

[0076] It can be understood that the opening k of the flow control valve, the liquid level difference h of the pouring tank / pouring tank (i.e. the first tank body / the second tank body), and the diameter d of the oil pouring pipeline are the three factors that affect the pouring flow rate v of the oil in the oil pouring pipeline; v is negatively correlated with d, and positively correlated with k and h. That is, the larger the diameter d of the oil pouring pipeline, the smaller the pouring flow rate v of the oil. The larger the opening k of the flow control valve, the larger the pouring flow rate v of the oil. Then, in practical applications, it can be calculated by the formula ( Δ h *S ) / ( Δt*S1 ) Calculate the oil pouring flow rate, where Δh is the level difference between the pouring tank and the pouring tank within the time period Δt. S is the cross-sectional area of ​​the pouring tank / pouring tank. S1 is the cross-sectional area of ​​the pouring pipeline, and the formula πd 2 / 4 is calculated, and d is the diameter of the oil pouring pipeline. In this way, the calculated oil pouring flow rate is compared with the specified target flow rate. If it is lower than the target flow rate, the opening of the flow control valve is increased. Otherwise, the opening of the flow control valve is reduced until the oil pouring flow rate is adjusted to the specified target flow rate.

[0077] In some optional implementations, adjusting the opening value of the flow regulating valve 13 according to the oil pouring flow rate can be achieved in any of the following ways. Specifically including:

[0078] (1) Determine the magnitude of the oil pouring flow rate and the target flow rate, and adjust the opening value of the flow regulating valve 13 according to the determination result; when the oil pouring flow rate is lower than the target flow rate, increase the opening value of the flow regulating valve 13; when the oil pouring flow rate is higher than the target flow rate, reduce the opening value of the flow regulating valve 13. That is, according to the change of the liquid level in the first tank body 1 or the second tank body 2, the current oil pouring flow rate of the oil is calculated by calculating formulas (1) and (2), and then the current oil pouring speed of the oil is compared with the target flow rate. When the oil pouring flow rate is lower than the target flow rate, increase the opening value of the flow regulating valve 13. When the oil pouring flow rate is higher than the target flow rate, reduce the opening value of the flow regulating valve 13.

[0079] (2) There is a corresponding relationship table between the liquid level difference of the first tank body 1, the oil pouring flow rate of the oil material and the opening value of the flow regulating valve 13. According to the corresponding relationship table, the opening value of the flow regulating valve 13 is adjusted to the opening value corresponding to the current liquid level difference of the first tank body 1 and the current oil pouring flow rate of the oil material. That is, the opening value of the flow regulating valve 13 is adjusted to the opening value corresponding to the current liquid level difference of the first tank body 1 and the current oil pouring flow rate of the oil material by directly looking up the table.
