Description

Technical Field

[0001] This utility model relates to the field of oil tank cleaning technology, and in particular to a device for laser removal of old paint from the inner wall of an oil tank. Background Technology

[0002] As large containers for storing petroleum and chemicals, oil storage tanks inevitably accumulate old paint layers, dirt, and other impurities on their inner walls over long periods of use.

[0034] This utility model discloses a laser-based old paint removal device for the inner wall of an oil storage tank. The device is used inside the oil storage tank to clean foreign matter deposited on its inner wall, including but not limited to dirt and old paint.

[0035] like Figures 1 to 5 As shown, the laser paint removal device for the inner wall of the oil storage tank includes a movable support 10, a transverse mechanism 20, a lifting mechanism 30, a laser cleaner 40, and a cooling mechanism 60. Specifically, the movable support 10 is used to move on the inner wall of the oil storage tank, the transverse mechanism 20 is mounted on the movable support 10, and the output end of the transverse mechanism 20 can move along a first direction, such as... Figure 1 As shown in direction a, the lifting mechanism 30 is located at the output end of the transverse mechanism 20. The output end of the lifting mechanism 30 can move up and down along the second direction, as shown in the second direction. Figure 1 As shown in direction b, both the laser cleaner 40 and the cooling mechanism 60 are located at the output end of the lifting mechanism 30. The laser cleaner 40 is used to remove dirt or old paint deposited on the inner wall of the oil tank. The laser cleaner 40, also known as a laser cleaning machine, is an advanced device that uses a high-energy laser beam to remove contaminants from the surface of an object. It features non-contact operation, no chemical agents, environmental friendliness, and high efficiency. The specific structure and working principle of the laser cleaner 40 are existing technologies and will not be detailed here. The cooling mechanism 60 includes a storage chamber 61, a return pipe 62, and a return pump 63. The storage chamber 61 has an output port and a return port, and is used to hold coolant. The return pipe 62 connects the output port and the return port to form a coolant circulation channel. The return pump 63 is located on the return pipe 62. Under the action of the return pump 63, the coolant circulates in the coolant circulation channel. Part of the structure of the return pipe 62 surrounds the laser cleaner 40 to cool it down.

[0036] During the use of the laser paint removal device for the inner wall of the oil tank, the moving bracket 10 can move the lateral moving mechanism 20, the lifting mechanism 30 and the laser cleaner 40 to the area to be cleaned inside the paint tank. By moving the lateral moving mechanism 20 to move the lifting mechanism 30 and by lifting the laser cleaner 40 to move the lifting mechanism 30, the laser cleaner 40, which is set at the output end of the lifting mechanism 30, can be positioned at a precise starting cleaning point. The laser cleaner 40 can then remove dirt and old paint using laser technology.

[0037] The laser paint removal device for the inner wall of the oil tank, through the coordinated movement of the movable support 10, the lateral movement mechanism 20, and the lifting mechanism 30, enables the laser cleaner 40 to move and clean the inner wall of the oil tank, expanding the cleaning range of the laser cleaner 40 and improving cleaning efficiency. Furthermore, the cooling mechanism 60 of this device can cool the laser cleaner 40. By arranging the return pipe 62 of the cooling mechanism 60 around the laser cleaner 40, the coolant circulates within the coolant circulation channel, continuously cooling the laser cleaner 40. This provides excellent cooling, contributing to improved operational stability and safety.

[0038] like Figure 2 As shown, in some embodiments, the movable support 10 includes a support 11, a mounting plate 12, and wheels 13. The support 11 is generally U-shaped; specifically, it includes a horizontal plate and two vertical plates connected to both ends of the horizontal plate and located on the same side of the horizontal plate.

Figure 1 As shown in the C-direction, the first direction, the second direction, and the third direction are arranged perpendicularly to each other. Of course, in other embodiments, the movable bracket 10 can also be set to other shapes as needed.

[0039] Continue to refer to Figure 2 As shown, in some embodiments, the lateral movement mechanism 20 includes a motor 21, a lead screw 22, and a slider 23. The lead screw 22 is rotatably connected to a bracket 11, and a slide rail 24 is provided on the bracket 11. The slider 23 is threadedly connected to the lead screw 22 and slidably connected to the slide rail 24. The output end of the motor 21 is connected to one end of the lead screw 22 and is used to drive the lead screw 22 to rotate around its own axis. Under the drive of the motor 21, the lead screw 22 rotates around its own axis, and the slider 23 on the lead screw 22 moves along the axial direction of the lead screw 22. The slide rail 24 can guide the movement of the slider 23 to improve the movement accuracy of the slider 23. Of course, in other embodiments, the lateral movement mechanism 20 can also be other mechanisms capable of lateral movement, such as a combination of a motor 21 and a conveyor belt mechanism, or a combination of a cylinder and a lateral movement rod.

[0040] Optionally, the transverse mechanism 20 is mounted on the horizontal plate of the bracket 11. The horizontal plate has a through hole extending in a first direction and penetrating the horizontal plate in a second direction. The horizontal plate includes a first part and a second part located on either side of the through hole in the first direction. A lead screw 22 extends along the first direction and is located within the through hole. One end of the lead screw 22 is rotatably connected to the first part, and the other end passes through the second part. A motor 21 is located outside the second part, and the motor shaft of the motor 21 is drively connected to the other end of the lead screw 22.

[0041] The horizontal plate also includes a third part and a fourth part located on both sides of the elongated through hole in the third direction. A slide rail 24 is disposed on either the third or fourth part. A slide groove 2321 is provided on the slider 23, and the slide groove 2321 and the slide rail 24 are slidably engaged. Optionally, a slide rail 24 is provided on both the third and fourth parts, with the two slide rails 24 spaced apart in the third direction and parallel to each other. Two slide grooves 2321 are provided on the slider 23, and the two slide rails 24 are slidably connected to the two slide grooves 2321 in a one-to-one correspondence.

[0042] Optionally, such as Figure 3 As shown, the slider 23 is roughly "I"-shaped, including a vertical portion 231 and a first horizontal portion 232 and a second horizontal portion 233 located on the third-direction sides of the vertical portion 231. The vertical portion 231 passes through a long through hole. The first horizontal portion 232 overlaps the top of the horizontal plate, and the second horizontal portion 233 is located below the horizontal plate. The second horizontal portion 233 can abut against the bottom surface of the horizontal plate or be separated from the bottom surface of the horizontal plate. A groove 2321 can be provided on at least one of the first horizontal portion 232, the second horizontal portion 233, and the vertical portion 231. Of course, in other embodiments, the slider 23 can also be configured as a "T" shape.

[0043] like Figure 3 As shown, in some embodiments, the lifting mechanism 30 includes an electric telescopic device 31, a telescopic rod 32, and a lifting plate 33. The electric telescopic device 31 is installed at the output end of the lateral movement mechanism 20. One end of the telescopic rod 32 is connected to the output end of the electric telescopic device 31, and the other end is connected to the lifting plate 33. The laser cleaner 40 and the cooling mechanism 60 are both disposed on the lifting plate 33. Optionally, the electric telescopic device 31 is installed below the second horizontal section 233. The laser cleaner 40 is installed below the lifting plate 33. Of course, in other embodiments, the lifting mechanism 30 can also use a cylinder or a hydraulic cylinder instead of the electric telescopic device 31.

[0044] Continue to refer to Figure 3 As shown, the lifting mechanism 30 also includes a guide shaft 34. A guide hole is provided on the output end of the transverse mechanism 20. One end of the guide shaft 34 is connected to the lifting plate 33, and the other end passes through the guide hole. In a specific embodiment, the width of the first horizontal portion 232 in the third direction is greater than the width of the second horizontal portion 233 in the third direction. A guide hole is provided on the first horizontal portion 232. Optionally, a guide sleeve 35 is provided in the guide hole, and the guide shaft 34 passes through the guide sleeve 35. Optionally, there are two guide holes and two guide shafts 34. The two guide shafts 34 are spaced apart in the third direction and located on both sides of the vertical portion 231. The two guide shafts 34 are correspondingly inserted into the two guide holes.

[0045] like Figure 4As shown, in some embodiments, the return pipe 62 includes a first pipe 621 and a second pipe 622. The first pipe 621 connects the output port of the storage chamber 61 and the pump inlet of the return pump 63, and the second pipe 622 connects the return port of the storage chamber 61 and the pump outlet of the return pump 63. A first control valve 64 is provided on the second pipe 622 to control the opening and closing of the second pipe 622. When the cooling mechanism 60 needs to be used, the return pump 63 is started and the first control valve 64 is opened. The coolant in the storage chamber 61 is output through the output port into the first pipe 621, and after passing through the first pipe 621, it enters the return pump 63 through the pump inlet, and then flows into the second pipe 622 through the pump outlet. After passing through the second pipe 622, it flows back into the storage chamber 61.

[0046] In some embodiments, the return pipe 62 includes a spiral section 6211, which is sleeved on the laser cleaner 40. This arrangement improves the cooling effect on the laser cleaner 40. Specifically, a portion of the structure of the first pipe 621 is spirally formed into the spiral section 6211.

[0047] Continue to refer to Figure 4 As shown, in some embodiments, the cooling mechanism 60 further includes an input pipe 65 and a second control valve 66. One end of the input pipe 65 is connected to the input port of the storage chamber 61, and the other end is used to connect to an external coolant source. The second control valve 66 is disposed on the input pipe 65 and is used to control the opening and closing of the input pipe 65. By opening the second control valve 66, coolant can be supplied to the storage chamber 61 through the input pipe 65.

[0048] During the process of using the laser cleaner 40 to remove old paint or dirt, a large amount of dust will be generated. (Continue to refer to...) Figure 5 As shown, the device for removing old paint from the inner wall of the oil storage tank using laser also includes a dust removal mechanism 50. The dust removal mechanism 50 is located at the output end of the lifting mechanism 30, and the suction end of the dust removal mechanism 50 is located close to the laser cleaner 40.

[0049] In some embodiments, the dust removal mechanism 50 includes a dust collector 51, a dust removal pipe 52, and a dust suction hood 53. The dust collector 51 is disposed at the output end of the lifting mechanism 30, the dust removal pipe 52 is connected between the dust suction port of the dust collector 51 and the dust suction hood 53, and the dust suction hood 53 is disposed facing the laser cleaner 40.

[0050] The device for removing old paint from the inner wall of the oil storage tank with laser also includes a control mechanism. The control mechanism can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the first control valve 64, the second control valve 66, and the reflux pump 63 to achieve their respective functions.

[0051] The working process of the laser-based paint removal device installed on the inner wall of the oil storage tank is as follows:

[0052] First, the bracket 11 and mounting plate 12 are moved by the wheels 13; then, the electric telescopic device 31 is activated, which drives the telescopic rod 32 to extend and retract, and the telescopic rod 32 drives the lifting plate 33 to rise and fall. During the lifting process, the guide shaft 34 moves within the guide sleeve 35 to achieve directional lifting and lowering of the lifting plate 33; then, the old paint is removed by the laser cleaner 40. At the same time, the dust collector 51 is activated, and the dust generated during the laser removal process is sucked into the dust collector 51 through the input end of the dust suction hood 53, and is also discharged through the return flow. The start of pump 63 and the opening of the first control valve 64 allow the coolant in storage chamber 61 to flow back into storage chamber 61 through return pipe 62, achieving coolant circulation. The coolant flowing through return pipe 62 can cool the laser cleaner 40, keeping the temperature of the laser cleaner 40 within a stable operating range. Finally, the start of motor 21 drives lead screw 22 to rotate, and slider 23 moves directionally under the guidance of two slide rails 24, realizing the moving and paint removal of laser cleaner 40.

[0053] This utility model provides a laser paint removal device for the inner wall of an oil storage tank that integrates movement, lifting, laser paint removal, dust removal, and cooling functions. It solves the problems of low efficiency, poor stability, and insufficient environmental friendliness in the prior art, and improves the cleaning efficiency and safety of oil storage tanks through the following technical effects:

[0054] First, the cooling system: The laser cleaner 40 is cooled in real time by circulating coolant to extend the equipment's lifespan;

[0055] Second, integrated design: the lateral movement mechanism 20 and the lifting mechanism 30 are controlled in a coordinated manner to achieve high-precision positioning;

[0056] Third, efficient dust removal: The dust hood 53 is combined with the pipeline system to thoroughly recover dust and ensure a clean working environment.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
