[0027] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] For the embodiment, please refer to Figure 1-7 , the present invention provides a technical solution:

[0029] An oil container cleaning device includes a ∟-shaped combined body 1. A five-way connection piece structure 9 is arranged on the side of the ∟-shaped combined body 1. The second connection piece 15 is formed by combining a straight pipe and a connecting elbow. The straight pipe and the connecting elbow are fixed by welding. The materials of the straight pipe and the connecting elbow are set as stainless steel. The collection box 601 is a triangular pentahedron structure formed by an empty bottom, an upper cover and a shape-stabilizing plate. The material of the collection box 601 is set as steel plate. The wall thickness of the round pipe 5 is set as 8 mm. The material of the round pipe 5 is set as stainless steel. The included angle between the round pipe 5 and the suction pipe orifice 7 is set as 150 degrees clockwise. The inclination angle of the shape-retaining plate 602 is set as 30 degrees clockwise. The material of the shape-retaining plate 602 is set as steel plate.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the inverted "乁"-shaped combined body 1 is formed by combining a 3-inch medium-pressure union 2 and a round pipe 5. The side of the top of the round pipe 5 is set as the output pipe orifice 3. At the bottom of the round pipe 5 located at the bottom of the 3-inch medium-pressure union 2, a feeding assembly 6 is provided. The feeding assembly 6 includes a collecting box 601. The side of the collecting box 601 is set as the mixture feeding orifice 603. At the bottom and the feeding orifice of the collecting box 601, there are inwardly inclined shape-retaining plates 602.

The outside of the round pipe 5 is fixedly connected to the main body mounting orifice 604. The bottom of the round pipe 5 extends into the collecting box 601. The side of the round pipe 5 is provided with a suction pipe orifice 7. The suction pipe orifice 7 is located inside the collecting box 601, and the suction pipe orifice 7 and the round pipe 5 are in a communicating state.

[0031] Among them, through the combined use of each structure, a rapid cleaning device for an oil container is formed. Compared with the traditional manual cleaning method, manual operation is reduced, and the labor cost is lowered. The operator only needs to perform simple monitoring and maintenance work to complete a large-area cleaning task, thus saving a large amount of labor costs. Moreover, when the operator enters the container, the high-speed liquid flow ejected through the handheld nozzle impacts, hollows out, breaks up, and pushes the sediment, making the deposited accumulation mixture into a semi-suspended state that can flow, which is more convenient for pushing. The operator cleans the inside of the container through the handheld nozzle, and can perform directional cleaning inside the tank, thereby ensuring the high efficiency of the cleaning process.

[0032] In this embodiment, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, the five-way connector structure 9 includes a five-way connector body 901, and the top and bottom of the five-way connector body 901 are respectively provided with a first connection port 903 and a fourth connection port 906, and the two sides of the five-way connector body 901 are respectively provided with a 2-inch female coupling 902, a second connection port 904 and a third connection port 905, and the port of the 2-inch female coupling 902 is fixedly connected with a pressure regulating throttle valve 8, and the discharge port of the pressure regulating throttle valve 8 is fixedly connected with a pressure relief connecting pipe 16, and the bottom of the pressure relief connecting pipe 16 extends to the interior of the collection box 601 through an adjustable pressure relief inlet 606, and the top of the first connection port 903 is fixedly connected with a first connector 11 through a 1-inch union, and a No. 1 nozzle 4 is provided at the port on the side of the first connector 11, and the No. 1 nozzle 4 and the first connector 11 are connected by external threads. The first nozzle 4 is fixedly connected to the U-shaped joint body 1, the top of the second connecting port 904 is fixedly connected to the high-pressure input hose 10 through a 1.5-inch union, the side of the third connecting port 905 is fixedly connected to the hand-held hose 12 through a 6-minute union, and a second nozzle 13 is arranged at the port of the hand-held hose 12, and the second nozzle 13 is fixed to the port of the hand-held hose 12 by an external thread connection, the bottom of the fourth connecting port 906 is fixedly connected to the second connecting piece 15 by a 1-inch union, the outside of the second connecting piece 15 is fixedly connected to the high-pressure inlet 605, and a third nozzle 14 is arranged at the port of the second connecting piece 15, and the third nozzle 14 and the port of the second connecting piece 15 are fixed by an external thread connection, and the top of the third nozzle 14 extends to the interior of the U-shaped joint body 1.

[0033] Among them, the Venturi effect double-effect or even multi-effect superposition technology is used in the cleaning process to quickly suck out and transport the petroleum waste in the storage tank, improve the transportation efficiency and reduce energy consumption, and ensure that in the transportation channel, whether it is particles, powder or liquid, it can be effectively transported, making the transportation process more efficient. In addition, the Venturi effect is used in the cleaning process. Without increasing pollution emissions, the mud concentrate is used to provide power for the efficient transportation of petroleum waste through a positive displacement pump, which not only reduces labor input and improves efficiency, but also achieves environmentally friendly waste reduction, reduces damage to the natural ecosystem, and maintains ecological balance.

[0034] Workflow of the present invention: When a petroleum container cleaning device designed with this solution is working, first connect the top of the second connection port 904 of the five-way connector body 901 to the drilling centrifuge feed pipe through the high-pressure input hose 10. Fix the first connector 11 and the second connector 15 connected to the five-way connector body 901 to the ∟-shaped combined body 1 respectively, and make the first nozzle 4 and the second nozzle 13 extend into the ∟-shaped combined body 1. The third nozzle 14 is held manually. Then, fixedly connect the pressure regulating throttle valve 8 to the side of the 2-inch female coupling 902, and extend the discharge port of the pressure regulating throttle valve 8 into the interior of the collection box 601. Then, lower the cleaning device into the access hole of the petroleum container to be cleaned. After the installation is completed, start the feed pump of the high-speed centrifuge to supply liquid to the piston pump, start the piston pump to pressurize the five-way connector body 901, and adjust the pressure regulating throttle valve 8 to make the device reach the best suction effect state. The five-way connector body 901 supplies liquid to the first nozzle 4, the third nozzle 14, and the second nozzle 13 of the device respectively in three ways, creating and increasing the Venturi suction effect of the device. During the cleaning process, manually hold the second nozzle 13 to impact, hollow out, and disperse the sediment. The mixed sediment is pushed to the mixture feed port 603 of the collection box 601, and the double-effect negative pressure suction port sucks the mixed sediment. The sucked sediment enters the device and is pushed at high speed by the third nozzle 14 to the connection point of the first nozzle 4, and is then accelerated and pushed out of the output port of the device by the first nozzle 4, thus realizing the cleaning and conveying process of petroleum waste.
