Description

Technical Field

[0001] This utility model relates to the field of oil sludge treatment technology, specifically to an in-tank mechanical conveying device for oil sludge. Background Technology

[0002] Chinese patent document CN219664655U discloses a high-efficiency oil sludge extraction device from the bottom of an oil tank, belonging to the category of oil sludge removal tools. It includes a collection platform and an oil sludge gun connected by a hose. The collection platform comprises an operating table, a power mechanism, an extraction mechanism, and an oil tank. The power mechanism is located on the operating table, and the extraction mechanism includes a collection tank and a piston cylinder. The collection tank has an inlet on its side wall, connected to the oil sludge gun via a hose, and a check valve at the inlet. The side wall of the collection tank is connected to the cylinder body of the piston cylinder. The piston cylinder contains a piston and a piston rod, which is connected to the power mechanism and driven by the power mechanism to move linearly back and forth. The collection tank has an outlet at its bottom, with a sealing cap; the oil tank is located below the outlet. Compared with existing technologies, this device is faster and more convenient.

[0003] However, in the above-mentioned solutions and existing technologies, the cleaning of residues after cleaning crude oil storage tanks is limited by factors such as the viscosity of the residues and the small operating space. At present, the main method is to manually bag and manually transport the residues to the outside of the tank. In order to save manpower, a tracked robot can be used to carry a suction head. The other end of the suction head is connected to a powerful suction device through a hose to extract the oil sludge from the tank and transport it into the oil sludge storage and bagging equipment for bagging. During the operation, the suction head is usually fixed on the tracked robot by tightening bolts and fixing clamps with auxiliary tools. The operation is cumbersome and inconvenient to disassemble and assemble the suction head, which affects the efficiency of oil sludge extraction and transportation from the tank. Improvements and optimizations are needed.

[0004] Therefore, this utility model proposes an in-tank mechanical conveying device for oil sludge to solve the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-4 The present invention provides the following two preferred embodiments:

[0022] Example 1: A mechanical conveying device for oil sludge inside a tank, comprising: a tracked robot body 1 and a conveying hose 4; an inclined support 2 is fixedly mounted on the tracked robot body 1, and a suction head 5 is fixedly mounted at one end of the conveying hose 4, with the other end of the conveying hose 4 connected to an oil sludge suction device; characterized in that: an installation platform 3 is fixedly mounted on the inclined support 2, and the suction head 5 is mounted on the installation platform 3 via an installation assembly and an auxiliary assembly; a fixing ring 6 in the installation assembly is fixedly sleeved on the peripheral wall of the suction head 5, and an installation arc groove 7 is formed on the side wall of the installation platform 3, the installation arc groove 7 engaging with the suction head 5, and the peripheral wall of the installation arc groove 7 being... An annular groove 8 is provided, which engages with a fixed ring 6. An annular sliding groove 9 is provided on the periphery of the mounting arc groove 7, and an arc-shaped lever groove 10 is provided on the side wall of the annular sliding groove 9. A semi-annular limiting plate 11 is movably engaged in the annular sliding groove 9, and the semi-annular limiting plate 11 engages with the suction head 5. A lever 12 is fixedly provided on the side wall of the semi-annular limiting plate 11. The lever 12 is movably engaged in the arc-shaped lever groove 10. A trapezoidal groove 13 is provided on the side wall of the mounting platform 3, and a trapezoidal block 14 is movably engaged in the trapezoidal groove 13. A positioning plate 15 is fixedly provided on the side wall of the trapezoidal block 14, and the positioning plate 15 engages with the lever 12.

[0023] In use, the suction head 5 is inserted into the mounting arc groove 7 so that the annular groove 8 engages with the fixing ring 6. The lever 12 is moved along the arc-shaped lever groove 10, causing the semi-annular limiting plate 11 to move within the annular sliding groove 9 until the lever 12 moves to the end of the arc-shaped lever groove 10. At this point, the semi-annular limiting plate 11 engages with the suction head 5, fixing the position of the suction head 5. Then, the trapezoidal block 14 is moved along the trapezoidal groove 13 to adjust the position of the positioning plate 15, so that the positioning plate 15 engages with the lever 12 and the position of the positioning plate 15 is fixed. This completes the quick installation of the suction head 5 onto the tracked robot body 1. The tracked robot body 1 drives the suction head 5 to move inside the crude oil storage tank. The sludge suction equipment connected to the other end of the conveying hose 4 is activated, sucking the sludge through the suction head 5 into the conveying hose 4 and transporting it to the sludge storage and bagging equipment connected to the other output end of the sludge suction equipment for bagging. The operation is simple and does not require auxiliary tools, enabling the suction head 5 to be quickly installed and removed from the tracked robot, improving the efficiency of sludge extraction and transportation inside the tank.

[0024] Example 2: Based on Example 1, the limiting slot 16 in the auxiliary component is opened on the side wall of the positioning plate 15, and the rotating plate 17 is rotatably set on the side wall of the mounting platform 3. The rotating plate 17 is engaged with the limiting slot 16. A knob bolt 18 is threadedly connected to the side wall of the rotating plate 17. A plug post 19 is fixedly set at the end of the knob bolt 18. A slot 20 is opened on the side wall of the mounting platform 3. The plug post 19 is inserted into the slot 20.

[0025] In use, after moving the positioning plate 15 to engage with the lever 12, rotate the rotating plate 17 to engage with the limiting slot 16 to fix the position of the positioning plate 15. Then, rotate the knob bolt 18 to move the insert post 19 into the slot 20 to fix the position of the rotating plate 17, ensuring that the position of the positioning plate 15 is fixed. The operation is simple and quick, further ensuring the installation stability of the suction head 5.
