[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the implementation methods in the specification are only part of the implementation methods of the present invention, not all of the implementation methods.

[0033] Combine Figures 1 to 3 As shown, the steam-washing and air-blasting sealing device for a light oil tanker provided in an embodiment of the present invention includes a sealing cover 4, a steam-washing circuit and an exhaust circuit.

[0034] The sealing cover 4 is used to be installed at the open end of the tank body of a light oil tanker truck. Specifically, the sealing cover 4 is installed at the tank mouth 3 of the tank body, so that the tank body forms a closed space. The method of sealing the tank body by the sealing cover 4 is not limited, as long as the sealing cover 4 can be detachably connected and the sealing of the connection can be guaranteed. For example, the connection can be achieved by providing a locking mechanism 2, which includes a hook provided at the end of the sealing cover 4 and a hanging groove provided on the inner wall of the tank mouth 3. After the sealing cover 4 is installed, the hook is rotated to engage with the hanging groove, completing the installation. A rubber pad can be provided at the connection position to enhance the sealing performance.

[0035] The steam-cleaning circuit includes a steam inlet pipe 8 and a liquid discharge pipe, which are provided through the sealing cover 4. The steam inlet pipe 8 is used to transport steam into the interior of the tank. One end of the liquid discharge pipe extends into the bottom of the tank, and the other end is connected to a waste liquid recovery device. Further optimized, the steam inlet pipe 8 is arranged along the axis of the sealing cover 4, with one end of the steam inlet pipe 8 extending into the interior of the tank and the other end connected to a steam generator. The end of the steam inlet pipe 8 extending into the tank is connected to a steam nozzle for outputting steam. When the tank needs to be steam-cleaned, the steam inlet pipe 8 transports steam into the tank, using the steam to remove oil stains on the inner wall of the tank and dissolve and soften oil residue and oil-containing debris at the bottom of the tank. As steam is continuously input, the internal pressure of the tank gradually increases, and the wastewater is discharged through the liquid discharge pipe to the waste liquid recovery device. In addition, the waste liquid recovery device can also be a sewage pumping device, which actively extracts the sewage in the tank to reduce residual wastewater.

[0036] The exhaust circuit includes a blast duct and an exhaust gas exhaust duct 9 that pass through the sealing cover 4. The blast duct is used to transport gas toward the interior of the tank body. One end of the exhaust gas exhaust duct 9 extends into the interior of the tank body, and the other end is connected to an exhaust gas recovery device. Further optimized, the exhaust gas exhaust duct 9 is arranged along the axial direction of the sealing cover 4, and a third valve body 10 is provided on the exhaust gas exhaust duct 9 for controlling its on and off, so as to facilitate the separation of sewage discharge and blasting. When the sewage is discharged, the blast duct introduces fresh air into the interior of the tank body, and the residual exhaust gas inside the tank body is discharged to the exhaust gas recovery device through the exhaust gas exhaust duct 9, thereby completing the replacement of the residual exhaust gas. Further optimized, the blast duct extends to the bottom of the tank body to increase the replacement effect of the exhaust gas.

[0037] The sealing cover 4 of the present invention is installed at the open end of the tank body, so that a closed space is formed inside the tank body. Steam is transported through the steam inlet pipe 8 to avoid steam loss, save steam resources, and accelerate the temperature rise inside the tank body, thereby increasing the steam washing effect and efficiency. The steam washing circuit and the exhaust circuit are integrated on the sealing cover 4, and the three processes of tank body steam washing, extracting sewage in the tank and blowing exhaust are completed at the same work station, thereby improving the car washing efficiency. The waste gas and waste liquid flow to the waste gas recovery equipment and the waste liquid recovery device respectively, thereby avoiding the pollution of the environment by the waste gas and waste liquid generated by the car washing operation.

[0038] like Figure 1 As shown, the sealing cover 4 is provided with an integrated pipe 1, one end of the integrated pipe 1 extends into the bottom of the tank body, and the other end is connected to the first pipe and the second pipe. Specifically, the integrated pipe 1 is connected to the steering pipe 6, and the steering pipe 6 is connected to the first pipe and the second pipe. Further optimized, the steering pipe 6 is a metal hose to increase strength and avoid damage. The first pipe is provided with a first valve body 5 for controlling its on and off, and the second pipe is provided with a second valve body 7 for controlling its on and off, so that the first pipe and the second pipe can work independently to avoid mutual influence. Figure 2 As shown, when the second valve body 7 is closed and the first valve body 5 is opened, the first pipe and the integrated pipe 1 form a drainage pipe for sealing and pumping out the sewage inside the tank. Figure 3 As shown, when the first valve body 5 is closed and the second valve body 7 is open, the second pipe and the integrated pipe 1 form a blast pipe for closed blast and exhaust operations. This design increases the integration of the device. Further optimized, the integrated pipe 1 is arranged along the axis of the sealing cover 4.

[0039] Combine Figures 1 to 3 As shown, the integrated duct 1 is a telescopic duct, capable of varying the length of its extension into the tank. Specifically, the duct's diameter gradually decreases as it approaches the tank's bottom. It comprises a first tube, a second tube, and a drive element. The first tube is threaded through the sealing cap 4. Multiple second tubes are provided, with each adjacent pair of second tubes being connected by a sleeve. The second tube closest to the sealing cap 4 is sleeved onto the first tube, forming a "fishing rod"-like structure. The drive element is used to extend and retract the multiple second tubes.

[0040] Specifically, a clamping block is provided on the outer periphery of the end of each second tube body, and the driving member is a winch. The soft rope of the winch passes through the interior of the first tube body and multiple second tube bodies in sequence, and is connected to the second tube body near the bottom of the tank body. When the telescopic pipe retracts, the winch rolls, and drives the second tube body near the bottom of the tank body toward the first tube body through the soft rope until the clamping block on its outer periphery contacts the end of the second tube body adjacent to it, and drives the second tube body toward the first tube body through the clamping block, and so on, until the telescopic pipe retracts. Conversely, the winch reverses, and the second tube body gradually extends under the action of its own weight until it is fully extended. With this design, the telescopic pipe retracts when not in use, which facilitates the transportation and storage of the sealing cover 41 and avoids taking up too much space.

[0041] The first valve body 5, the second valve body 7 and the third valve body 10 of the present invention can be manual valves, electric valves, electromagnetic valves or pneumatic valves, etc., and their specific configuration is not limited.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
