Description

Technical Field

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

[0002] A double - layer oil tank device is a container for storing liquids such as petroleum, diesel, and chemicals. It consists of an inner oil tank and an outer oil tank. The main purpose of this design is to improve the safety and environmental friendliness of the oil tank to prevent environmental pollution in case of leakage. Double - layer oil tanks usually include the following components: Inner tank body: The tank body directly in contact with the storage medium, usually made of stainless steel or corrosion - resistant materials. Outer tank body: The tank body wrapped outside the inner tank body, which plays a role of protection and isolation, and usually also has certain corrosion - resistant properties.

[0003] After the oil liquid inside the inner shell of the existing double - layer oil tank device leaks, because it is inside the double - layer oil tank, it cannot be quickly detected by personnel, and the oil leaked between the inner shell and the outer shell of the inner shell tank cannot be quickly collected, resulting in waste of oil. To avoid accidents, personnel need to quickly disassemble the double - layer oil tank to drain the oil liquid leaked between the inner shell and the outer shell. Moreover, the oil liquid is difficult to collect and recycle, which not only makes personnel laborious but also increases economic losses. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a double - layer oil tank device, which can alarm and quickly collect the oil liquid leaked from the inner shell, enabling operators to respond quickly, and can also reduce the loss of oil liquid, reduce economic losses, and reduce environmental pollution.

[0005] To solve the above - mentioned technical problems, the technical solution adopted by the utility model is: A double - layer oil tank device includes a bottom plate. At the upper end of the bottom plate, there are two corresponding brackets. An outer shell is placed between the inner arc surfaces of the two brackets. At the upper end of the outer shell, there are two lifting hooks. There is a cavity between the outer shell and the inner shell. The inner shell is arranged inside the outer shell. At the upper end of the outer arc surface of the outer shell, there is an inlet pipe, which is connected to the inside of the inner shell. At the lower end of the outer arc surface of the outer shell, there is an outlet pipe, which is connected to the inside of the inner shell. A solenoid valve I is connected in series inside the outlet pipe. At the upper end of the bottom plate, there is an oil - liquid leakage collection mechanism. A brush cleaning mechanism is arranged inside the inner shell. The oil - liquid leakage collection mechanism includes a collection box arranged at the upper end of the bottom plate. A connecting pipe is arranged in a communication hole opened at the upper end of the collection box, and the communication hole is connected to the inside of the outer shell. An oil discharge hole is opened on the front side of the collection box, and an oil discharge pipe is arranged inside it. A solenoid valve II is connected in series in the middle of the oil discharge pipe. A liquid level sensor is arranged in an installation opening opened at the lower - right side of the outer arc surface of the outer shell. A warning lamp is arranged at the upper end of the outer shell.

[0006] As a further improvement of the present utility model, mounting holes are provided at the four corners of the bottom plate.

[0007] As a further improvement of the present utility model, the scraping and cleaning mechanism includes a rotating column rotatably arranged inside the inner shell. The left end of the rotating column penetrates outside the outer shell. A scraping brush holder is fixedly sleeved on the outer arc surface of the rotating column. The scraping brush holder is in contact with the inner arc surface of the inner shell. An electric drive unit for driving the rotation of the rotating column is arranged at the left end of the outer shell. The electric drive unit includes a motor arranged at the left end of the outer shell. The output shaft of the motor is connected to the left end of the rotating column through a coupling.

[0008] As a further improvement of the present utility model, a control panel is arranged on the right side of the outer shell. The motor, solenoid valve I, solenoid valve II, warning lamp and liquid level sensor are all electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] First, the oil liquid can be added into the inner shell through the oil inlet pipe to realize the storage of the oil liquid. By controlling the opening of solenoid valve I through the control panel, the oil liquid can be discharged through the oil outlet pipe, and the outer shell plays a role of protection and isolation, realizing double protection of the oil liquid.

[0011] Second, by controlling the operation of the liquid level sensor through the control panel, when the oil liquid stored in the inner shell leaks, the oil liquid will leak into the cavity between the outer shell and the inner shell. At this time, the oil liquid will trigger the liquid level sensor, causing the liquid level sensor to transmit a signal to the control panel. The control panel controls the warning lamp to flash red light, indicating that the oil liquid leaks. At the same time, due to the influence of gravity, the oil liquid will enter the inside of the collection box through the connecting pipe, realizing the collection of the leaked oil liquid. The solenoid valve II can also be controlled to be opened through the control panel, so that the oil liquid is discharged from the inside of the collection box, facilitating the recycling and utilization of the oil liquid by personnel. It can alarm and quickly collect the leaked oil liquid in the inner shell, enabling the operator to respond quickly, reducing the loss of oil liquid, reducing economic losses, and reducing environmental pollution.

[0012] Third, by controlling the operation of the motor through the control panel, the output shaft drives the scraping machine on the rotating column to scrape off the solidified oil liquid on the inner arc wall of the inner shell, facilitating the subsequent flushing and cleaning of the double-layer oil tank by personnel.

[0013] Fourth, through the lifting hook, it is convenient for personnel to lift and move the double-layer oil tank through lifting facilities, facilitating personnel to use. Description of the Drawings

However, the protected content of the present utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0021] Such as Figure 1 , 2, as shown in Figures 3 and 4, a double-layer oil tank device includes a bottom plate 101. At the upper end of the bottom plate 101, there are two corresponding brackets 103. Between the inner arc surfaces of the two brackets 103, there is an outer shell 106 placed. At the upper end of the outer shell 106, there are two lifting hooks 104. There is a cavity between the outer shell 106 and the inner shell 111. Inside the outer shell 106, there is an inner shell 111. At the upper end of the outer arc surface of the outer shell 106, there is an oil inlet pipe 105, and the oil inlet pipe 105 is connected to the inside of the inner shell 111. At the lower end of the outer arc surface of the outer shell 106, there is an oil outlet pipe 109, and the oil outlet pipe 109 is connected to the inside of the inner shell 111. Inside the oil outlet pipe 109, there is a solenoid valve 110 in series. At the upper end of the bottom plate 101, there is an oil leakage collection mechanism. Inside the inner shell 111, there is a scraping and cleaning mechanism. The scraping and cleaning mechanism includes a rotating column 302 rotatably arranged inside the inner shell 111. The left end of the rotating column 302 penetrates outside the outer shell 106. A scraping brush holder 303 is fixedly sleeved on the outer arc surface of the rotating column 302, and the scraping brush holder 303 is in contact with the inner arc surface of the inner shell 111. At the left end of the outer shell 106, there is an electric drive unit for driving the rotating column 302 to rotate. The electric drive unit includes a motor 301 arranged at the left end of the outer shell 106, and the output shaft of the motor 301 is connected to the left end of the rotating column 302 through a coupling.

[0022] As Figure 1 , 3 , as shown in Figure 4, the oil leakage collection mechanism includes a collection box 202 arranged at the upper end of the bottom plate 101. Inside the communication hole opened at the upper end of the collection box 202, there is a communication pipe, and the communication hole is connected to the inside of the outer shell 106. Inside the drain hole opened on the front side of the collection box 202, there is a drain pipe 201, and a solenoid valve 204 is in series in the middle of the drain pipe 201. Inside the installation opening opened at the lower right end of the outer arc surface of the outer shell 106, there is a liquid level sensor 203. At the upper end of the outer shell 106, there is a warning light 107.
