[0001] The utility model relates to the technical field of drainage equipment for oil storage tanks, in particular to a full-automatic storage tank drainage skid. Background Art

[0002] The function of the oil storage tank is to store and transport oil. After the material transporter transports the oil to the oil storage tank, the components in the oil storage tank are a mixture of oil and water. After a period of sedimentation, the oil and water are separated after precipitation, forming a stratified state. After the oil and water are separated, they are dehydrated through the oil storage tank dehydration valve group, and finally transported to the designated material recipient through the delivery pump.

[0003] At present, the drainage of oil storage tanks is manually operated or semi-automatically drained with personnel on site. The drainage methods are visual, floating or other heavy detection methods. In the actual dehydration process, due to the different experience of operators, the quality of the dehydration also varies. When the color of oil and water is similar during the dehydration of oil storage tanks, it is difficult to distinguish between oil and water, which can easily cause oil leakage accidents.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0011] a flow meter mounted at the rear end and arranged downstream of the diaphragm pump;

[0012] A controller is installed on the base, and the controller signal is connected to the electric valve, the diaphragm pump, the oil-water sensor and the flow meter.

[0013] Furthermore, the oil-water sensor is a capacitive oil-water sensor.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 5 As shown, the utility model provides a fully automatic tank drainage skid, including: a base 1, an electric valve, a diaphragm pump 2, an oil-water sensor 3, a flow meter 4, and a controller 5.

[0030] The electric valve, the diaphragm pump 2, the oil-water sensor 3, the flow meter 4, and the controller 5 are integrated and installed on the base 1.

[0031] Specifically, two opposite ends of the base 1 are respectively formed with lifting ears 16. A connecting pipe 15 is mounted on the base 1. The connecting pipe 15 has a front end and a rear end. The front end is detachably connected to the drain port of the oil storage tank 6. The rear end is detachably connected to the sewage tank 7.

[0032] In this embodiment, see Figure 1 As shown, the base 1 includes a supporting frame 11 , a longitudinal beam 12 , a transverse beam 13 and a column 14 .

[0033] The support frame 11 is a steel structure frame. The support frame 11 is rectangular. Lifting ears 16 are installed at opposite ends of the support frame 11.

[0034] The longitudinal beam 12 is connected between opposite ends of the support frame 11. The transverse beam 13 is connected between the longitudinal beam 12 and the side of the support frame 11. A plurality of columns 14 are vertically arranged on the transverse beam 13. The connecting pipes 15 are installed on the plurality of columns 14.

[0035] As a preferred embodiment, two lifting ears 16 are respectively installed at each end of the support frame 11. The two lifting ears 16 are arranged at intervals along the wide band direction of the support frame 11.

[0036] The electric valve is installed at the front end of the connecting pipe 15. The electric valve is used to control the opening and closing of the front end of the connecting pipe.

[0037] The diaphragm pump 2 is installed on the middle part of the connecting pipe 15. The diaphragm pump is used to transport fluid.

[0038] The diaphragm pump uses a high-head diaphragm pump, which can transport the discharge medium or fluid over a long distance. The diaphragm pump does not require a head to start, which can achieve no residual medium in the pipeline and detection cavity, and will not cause residual night deposition, deterioration, and blockage.

[0039] The oil-water sensor 3 is installed at the front end of the connecting pipe 15 and is arranged upstream of the diaphragm pump 2. The oil-water sensor 3 is used to collect the water content of the fluid in the front end.

[0040] As a preferred implementation, the oil-water sensor 3 is a capacitive oil-water sensor.

[0041] The capacitive oil-water sensor uses the difference in electric potential formed by oil and water in the electric field between two plates to quantitatively detect oil, water, and oil-water mixtures.

[0042] The flow meter 4 is installed at the rear end of the connecting pipe 15 and is arranged downstream of the diaphragm pump 2 .

[0043] As a preferred embodiment, the flow meter 4 is a vortex flow meter to measure the discharge medium or fluid. The data of the flow meter is transmitted to the controller for flow measurement.

[0044] The controller 5 is installed on the base. The controller 5 is connected to the electric valve, the diaphragm pump 2, the oil-water sensor 3 and the flow meter 4 by signal.

[0045] The controller collects, analyzes and controls the signals of electric valves, diaphragm pumps, oil-water sensors and flow meters. The controller measures the flow of the discharge medium or fluid, and calculates the amount of discharged oil, water and oil-water mixture in combination with the sensor signal. The calculated data is used for discharge control to make it suitable for different process requirements.

[0046] The controller has functional expansion capabilities and can provide expansion of I / O signals, analog signals, communications, etc., providing peripheral devices with signal acquisition, control, communication and other functions.

[0047] In this embodiment, the controller is connected to an explosion-proof touch screen, through which the settings of drainage parameters and control parameters, equipment status and process progress, fault and alarm display and recording, etc. can be displayed.

[0048] The utility model provides a method for discharging an oil storage tank using a fully automatic storage tank drainage skid, comprising the following steps:

[0049] S1. After the oil is left to settle in the oil storage tank, moisture accumulates at the bottom of the oil storage tank.

[0050] S2, hoist the fully automatic tank drainage skid to the discharge port of the oil tank, and connect the front end of the connecting pipe to the discharge port of the oil tank. The drainage process of the fully automatic tank drainage skid is that the controller 5 sends a valve opening command to the electric valve.

[0051] S3. The controller 5 sends a start command to the diaphragm pump 2.

[0052] S4. The controller 5 reads the reading of the oil-water sensor 3.

[0053] S5. The controller 5 continuously reads the value of the flow meter and accumulates it.

[0054] S6. When the value of the oil-water sensor read by the controller 5 reaches the set value, a closing command is sent to the electric valve 2.

[0055] S7, the controller 5 reads the value of the flow meter, and when the value reaches a preset value, the controller 5 sends a stop command to the diaphragm pump 2.

[0056] The fully automatic tank drainage skid of the utility model integrates the electric valve, diaphragm pump, oil-water sensor, flow meter and controller on the base. The controller controls the electric valve, diaphragm pump, oil-water sensor and flow meter, so that multiple components cooperate with each other, thereby realizing the automatic discharge of the discharge medium of the oil storage tank. On the one hand, it saves manpower and reduces costs. On the other hand, it avoids the use of visual drainage methods and the reliance on the experience of the operator, thereby accurately controlling the discharge of the discharge medium and avoiding oil leakage accidents.

[0057] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
