Description

Technical Field

[0001] The utility model belongs to the technical field of petrochemical equipment, and particularly relates to a glass fiber double-layer oil tank. Background Art

[0002] FF stands for glass fiber reinforced plastic double-layer oil tank. Both the inner and outer layers are made of glass fiber reinforced plastic, with a through gap space in the middle. The advantage of a double-layer oil tank is that even if the inner tank is damaged, the oil in the tank can only seep into the gap between the inner and outer tanks, and will not directly enter the soil. It is also equipped with a leakage detection device that can monitor the gap space 24 hours a day.

[0003] However, there are certain technical problems: it is difficult to clean the leaked liquid in the gap space and replace the detection liquid, and the axis of most double-layer oil tanks is circular, which may cause rolling during transportation and placement, affecting transportation efficiency and placement stability. Therefore, a glass fiber double-layer oil tank is set here to solve the above technical problems. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a glass fiber double-layer oil tank.

[0007] A plurality of arc-shaped connecting blocks are connected between the inner wall of the outer layer of the oil tank and the outer wall of the inner layer of the oil tank, and a second float liquid level sensor is connected between the outer layer of the oil tank and the inner layer of the oil tank.

[0008] It is further defined that the sealing cover is threadedly connected to the oil inlet cylinder, the inner wall of the sealing cover is connected to a sealing block, the outer wall of the shaft body at the end of the sealing block is connected to a sealing ring, and the sealing ring is contact-connected to the inner wall of the oil inlet cylinder. Such a structural design can enhance the sealing and leak-proof effect of the sealing cover and the oil inlet cylinder.

[0009] It is further defined that the oil outlet cylinder and the liquid outlet pipe are both arranged at a certain inclined angle. Such a structural design improves the liquid outlet efficiency.

[0010] It is further defined that the double-layer gap cavity is connected to a guide ramp at the bottom of the inner wall of the outer layer of the oil tank. Such a structural design can prevent liquid accumulation in the double-layer gap cavity when liquid needs to be discharged.

Such a structural design facilitates opening and closing the liquid adding tube and improves the sealing and leak-proof effect between the liquid adding tube and the outer layer of the oil tank.

[0012] The beneficial effects of the utility model are:

[0013] 1. The first float liquid level sensor is connected to the double-layer gap cavity, and the second float liquid level sensor is connected to the inner layer of the oil tank, so as to automatically monitor the liquid level height in the inner layer of the oil tank and detect the oil height and leakage in the inner layer of the oil tank in time;
