[0051] A central rotary oil storage tank mud removal and reduction processing device, comprising:

[0052] Oil storage tanks;

[0053] The center seat 1 is located at the geometric center of the bottom of the oil storage tank;

[0054] The rotating seat 2 is rotatably mounted on the central seat 1 through a rotating mechanism;

[0055] The swing arm 3 is hinged on the rotating seat 2 through a deflection mechanism;

[0056] The sludge suction filter head 10 and the hydraulic jet head 11 are arranged on the swing arm 3 and pass through the area between the center seat 1 and the oil storage tank through the deflection of the swing arm 3 and the rotation of the rotating seat 2;

[0057] The main suction and discharge pipe 19 and the main injection pipe 20 have one end located outside the oil storage tank, and the other end extends to the center seat 1, and are connected to the sludge suction filter head 10 and the hydraulic injection head 11 through the sludge suction pipe and the hydraulic injection pipe respectively.

[0058] When cleaning operations are not in progress, the swing arm 3 can be folded under the rotating seat 2 to reduce the impact of the oil tank on the swing arm 3 during daily use. When cleaning operations are required, the deflection angle of the swing arm 3 and the position of the rotating seat 2 are adjusted in real time, so that the sludge suction filter head 10 and the hydraulic injection head 11 can pass through the entire bottom range of the oil tank, and high-pressure liquid can be sprayed through the injection main pipe 20 to flush up the sludge at the bottom, and the sludge can be extracted in real time in combination with the suction effect of the sludge suction filter head 10.

[0059] Specifically, the sludge suction pipe includes:

[0060] The first suction pipe 4 is mounted on the rotating seat 2;

[0061] The second suction pipe 5 is mounted on the swing arm 3;

[0062] The suction connecting pipe 6 is arranged between the first suction pipe 4 and the second suction pipe 5 and is connected to the two in a rotational sealing manner, and is located at the hinge of the rotating seat 2 and the swing arm 3.

[0063] Specifically, the hydraulic jet pipe includes:

[0064] The first injection pipe 7 is mounted on the rotating seat 2;

[0065] The second injection pipe 8 is mounted on the swing arm 3;

[0066] The injection connecting pipe 9 is arranged between the first injection pipe 7 and the second injection pipe 8 and is connected to the two in a rotational sealing manner, and is located at the hinge of the rotating seat 2 and the swing arm 3.

[0067] Since the sludge suction pipe and the hydraulic injection pipe need to pump out the sludge and input high-pressure fluid respectively, the traditional hose structure is not applicable, and the rotation state of the swing arm 3 must be met. Therefore, the first suction pipe 4, the second suction pipe 5, the suction connecting pipe 6, the first injection pipe 7, the second injection pipe 8, and the injection connecting pipe 9 are designed as U-shaped pipe structures, and the suction connecting pipe 6 and the injection connecting pipe 9 meet the requirements of their rotational sealing connection. At the same time, the connection between the sludge suction pipe and the extraction and discharge main pipe 19 and the connection between the hydraulic injection pipe and the injection main pipe 20 are also in a rotational sealing state. The first suction pipe 4, the second suction pipe 5, the first injection pipe 7, and the second injection pipe 8 are U-shaped structures with lower openings, and the suction connecting pipe 6 and the injection connecting pipe 9 are U-shaped structures with upper openings, so as to facilitate the connection between the pipelines, and at the same time, the sludge suction filter head 10 and the hydraulic injection head 11 can fit the bottom of the oil storage tank as much as possible.

[0068] Specifically, the rotating mechanism includes:

[0069] A driving gear 14 is provided on one side of the center seat 1;

[0070] The linkage gear ring 13 is disposed on the rotating seat 2 and meshes with the driving gear 14 .

[0071] The rotating mechanism drives the rotating seat 2 to rotate through the driving structure of the gear ring, thereby driving the swing arm 3 to rotate along the center seat 1.

[0072] Specifically, the deflection mechanism includes:

[0073] The swing arm driving gear 15 is arranged on the rotating seat 2;

[0074] The rotary drive gear 18 is provided at the hinge between the rotary seat 2 and the swing arm 3;

[0075] The swing arm linkage shaft 16 has swing arm linkage gears 17 at both ends thereof which mesh with the swing arm driving gear 15 and the rotation driving gear 18 respectively.

[0076] The swing arm 3 is driven to deflect by gear meshing to achieve coverage of various angular positions.

[0077] In some embodiments, it also includes: a rotation transmission box 12 and a deflection transmission box; the output end of the rotation transmission box 12 is connected to the driving gear 14, and the input end of the rotation transmission box is externally connected to a rotation transmission shaft 21 extending to the outside of the oil storage tank. The output end of the deflection transmission box is connected to the swing arm driving gear 15, and the input end of the deflection transmission box is externally connected to a deflection transmission shaft 22 extending to the outside of the oil storage tank.

[0078] The rotating transmission shaft 21 and the deflection transmission shaft 22 can be externally connected to a rotating drive motor to realize the rotation drive of the rotating transmission shaft 21 and the deflection transmission shaft 22, and then drive the driving gear 14 and the swing arm driving gear 15 to rotate through the transmission of the rotating transmission box 12 and the deflection transmission box. The purpose of the above arrangement is to place the driving unit outside the oil storage tank to reduce its risk of damage, so as to facilitate later maintenance. As most of the related transmission components are driven by the cooperation of the gear structure, they can effectively use the lubricity of the oil stored in the oil storage tank itself to reduce its transmission wear, thereby greatly reducing the maintenance burden of the equipment in the later stage.

[0079] In some embodiments, a plurality of hydraulic jet heads 11 are provided and distributed around the outer circumference of the sludge suction filter head 10 .

[0080] In some embodiments, the two ends of the rotating seat 2 are provided with extensions, and each extension is hinged with a swing arm 3. Specifically, there are two left and right extensions, and each extension is provided with a swing arm 3. The length of the extension and the swing arm 3 should be greater than the radius of the oil tank, and the lengths of the two should be adjusted to be consistent as much as possible, so that the swing arm 3 can be folded and stored under the extension.

[0081] A control system for a central rotary oil tank sludge removal and reduction processing device, further comprising:

[0082] The automatic control system is used to monitor the deflection angle of the swing arm 3, the rotation state of the rotating seat 2, the liquid level height and pressure in the oil storage tank, and the opening state of the exhaust main pipe 19 and the injection main pipe 20 in real time.

[0083] Its working principle is:

[0084] An external interface box 23 is provided on one side of the oil storage tank, and connection interfaces of the extraction and exhaust main pipe 19, the injection main pipe 20, the rotating transmission shaft 21, and the deflection transmission shaft 22 are respectively provided in the external interface box 23. Among them, the rotating transmission shaft 21 and the deflection transmission shaft 22 need to rotate, so dynamic sealing treatment is required at the rotating joints to prevent leakage.

[0085] The injection main pipe 20 can be externally connected to a high-pressure water tank or a liquid circulation tank to provide high-pressure fluid to the hydraulic injection head 11 through a high-pressure pump to impact the sludge accumulated and compacted at the bottom of the tank, thereby dispersing it and increasing its fluidity.

[0086] The main pumping and draining pipe 19 is externally connected to a mud pump unit, so that the washed-up sludge can be promptly pumped out through the effect of negative pressure adsorption, so as to achieve the purpose of pumping the sludge accumulated and hardened in the tank out of the tank.

[0087] In the above process, the rotating seat 2 rotates, which not only ensures that every position of the tank bottom can be touched, but also provides a certain rotation stirring force to reduce the sedimentation of the sludge and improve the fluidity of the mixed fluid.

[0088] The corresponding liquid level height sensing unit and pressure sensing unit in the tank are used to monitor the liquid level and the pressure in the tank so as to make corresponding adjustments in real time. At the same time, corresponding position sensing units can be set to monitor the path positions of the sludge suction filter head 10 and the hydraulic injection head 11, and form a corresponding planning path image, so as to facilitate the operator to dynamically follow up the processing progress, that is, the completed area and the unfinished area at any time to ensure the efficiency of the processing.

[0089] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
