Description

Technical Field

[0001] The utility model relates to the technical field of double-layer oil tanks, in particular to a leakage-proof SF double-layer tank. Background Art

[0002] Double-layer oil tanks refer to three types: SS oil tanks, SF oil tanks, and FF oil tanks. They are also equipped with leakage detection devices, which can monitor the gap space 24 hours a day to ensure the safe use of the oil tanks. With the gradual improvement of my country's environmental protection laws and regulations, the use of this safe and environmentally friendly double-layer tank in gas stations will inevitably become a trend.

[0003] At present, the scale of SF double-layer tanks is large. During use, they may be deformed due to irregular settlement of the soil layer, resulting in leakage. The large scale of the tank also means that more refined oil is stored. Under long-term storage conditions, the tank may also cause deformation and eventually cause leakage. Based on this, we propose an improved leak-proof SF double-layer tank. Utility Model Content

[0004] The main purpose of the utility model is to provide a leakage-proof SF double-layer tank, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A leak-proof SF double-layer tank comprises an outer tank, an inner tank, a spare tank supporting ring and a buckle ring, a balance pipe is sleeved between the inner tank and the spare tank, a detection pipe is sleeved between the outer tank and the inner tank, the other end of the detection pipe is fixedly connected to the balance pipe, the outer tank is arranged between the supporting ring and the buckle ring, a stud is rotatably connected to the middle part of the lower end of the supporting ring, a sleeve is threadedly sleeved on the lower end of the stud, a support plate is fixedly connected to the lower end of the sleeve, oblique braces are hinged on both sides of the lower end of the supporting ring, and a connecting plate is hinged on the other end of the oblique brace.

[0007] As a further solution of the utility model, an alarm and a wireless pressure sensor are respectively provided on the detection tube, and the horizontal height of the upper end of the backup tank is smaller than the horizontal height of the lower end of the outer tank.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting up a balance pipe, a detection pipe, an alarm, a wireless pressure sensor and a spare tank structure, when the inner tank needs to store a large amount of finished oil for a long time, part of the finished oil can be exported to the spare tank through the balance pipe for storage, so as to avoid deformation and rupture of the inner tank caused by excessive weighing. A detection pipe is set between the inner tank and the outer tank, which can guide and collect the finished oil leaked from the inner tank. At the same time, the wireless pressure sensor can detect and send an alarm signal to the terminal in time to remind the backstage personnel, and the alarm can be used to remind the nearby personnel to deal with it in time.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a leak-proof SF double-layer tank comprises an outer tank 1, an inner tank 2, a supporting ring 8 and a buckle 15 for a spare tank 3, a balancing pipe 4 is sleeved between the inner tank 2 and the spare tank 3, a detection pipe 5 is sleeved between the outer tank 1 and the inner tank 2, and the other end of the detection pipe 5 is fixedly connected to the balancing pipe 4, the outer tank 1 is arranged between the supporting ring 8 and the buckle 15, a stud 9 is rotatably connected to the middle part of the lower end of the supporting ring 8, a sleeve 10 is threadedly sleeved on the lower end of the stud 9, a support plate 12 is fixedly connected to the lower end of the sleeve 10, and oblique braces 11 are hinged on both sides of the lower end of the supporting ring 8, and a connecting plate 13 is hinged on the other end of the oblique brace 11.

[0023] In this embodiment, an alarm 6 and a wireless pressure sensor 7 are respectively provided on the detection tube 5. The horizontal height of the upper end of the spare tank 3 is smaller than the horizontal height of the lower end of the outer tank 1, which facilitates the oil in the balance tube 4 and the detection tube 5 to flow into the spare tank 3.

[0024] In this embodiment, the support ring 8 is correspondingly arranged on the upper end of the buckle ring 15, and the support ring 8 is fixed to the buckle ring 15 by bolts, which is convenient for disassembly and assembly.

[0025] In this embodiment, a plurality of support rings 8 are provided, and the plurality of support rings 8 are evenly distributed at the lower end of the outer tank 1 , and reinforcing columns 14 are fixedly sleeved between the plurality of support rings 8 to improve the structural strength of the support rings 8 .

[0026] In this embodiment, the inner tank 2 is fixedly arranged in the outer tank 1 , and an inspection hole and a vent hole are respectively opened at the upper end of the inner tank 2 , and the inspection hole and the vent hole are distributed between two adjacent support rings 8 .

[0027] In this embodiment, the connecting plate 13 and the supporting plate 12 are located at the same horizontal height, and the supporting plate 12 and the connecting plate 13 are welded and fixed. After adjusting the height of the support ring 8 relative to the supporting plate 12 before installation, a steel plate can be installed between the connecting plate 13 and the supporting plate 12 for compensatory welding.

[0028] In this embodiment, the detection tube 5 is arranged to be tilted downward, and the horizontal height of one end of the detection tube 5 located in the outer tank 1 is greater than the horizontal height of the end connected to the balance tube 4, so as to prevent the oil in the balance tube 4 from being diverted into the detection tube 5. According to actual conditions, a one-way valve can also be installed on the detection tube 5 to prevent the oil from flowing back.

[0029] It should be noted that the utility model is a leak-proof SF double-layer tank. When in use, according to the preset tank placement height, the stud 9 is rotated to adjust its extension length relative to the sleeve 10, thereby adjusting the height of the support ring 8, and then a steel plate is installed between the support plate 12 and the connecting plate 13 for welding and fixing, so as to increase the contact area between the bottom of the support structure and the ground, and avoid irregular settlement of the soil layer, which may affect the tank body. After the tank body is placed on the support ring 8, the buckle 15 is buckled on the upper end of the tank body and fixed by bolts, so that the tank body is fixed by the support ring 8 and the buckle 15. It is determined that during the storage of finished oil, if too much finished oil is stored in the tank, when the liquid level exceeds the balance pipe 4, the excess part will be introduced into the spare tank 3 through the balance pipe 4 for storage. When the inner tank is deformed and broken, the oil enters the interlayer between the outer tank 1 and the inner tank 2, and finally enters the detection tube 5 and is introduced into the spare tank 3 for storage. When the finished oil flows through the detection tube 5, the pressure change is detected by the wireless pressure sensor 7, and a wireless signal will be sent to the terminal to remind the background personnel, and at the same time, the alarm 6 will be controlled to turn on the alarm to remind the surrounding site personnel to deal with it in time.
