[0001] The present invention relates to the technical field of spraying equipment, and particularly relates to a spraying device for the inner lining of an anti-corrosion storage tank. Background Art

[0002] In many industrial fields such as chemical industry, petroleum, and food, anti-corrosion storage tanks are important equipment for storing various corrosive liquids. In order to ensure the service life of the storage tank and the safety of the stored liquid, the anti-corrosion spraying work of the inner lining of the storage tank is crucial.

[0003] Existing spraying devices mostly adopt fixed nozzle angles and cannot be adjusted according to the shape and structure of the inner wall of the storage tank, resulting in difficulty in uniformly spraying the paint thickness on parts such as the special-shaped stepped surface and the bottom surface of the storage tank during the spraying process, affecting the anti-corrosion effect. Moreover, after spraying inside the existing anti-corrosion storage tank, it usually needs to be naturally dried, and the drying speed of the paint is slow, which not only prolongs the production cycle but also may cause defects on the surface of the paint film due to environmental factors, affecting the anti-corrosion performance. Summary of the Invention

[0004] Embodiments of the present invention provide a spraying device for the inner lining of an anti-corrosion storage tank to solve the problems in the prior art.

Two sets of symmetrically arranged fixing mechanisms are fixedly installed on the edge of the sealing ring plate, and an exhaust gas treatment mechanism is arranged on the surface of the outer pipe to filter the exhaust gas generated when spraying the inner wall of the anti-corrosion storage tank.

[0007] Furthermore, the lifting mechanism includes a gantry fixedly installed on the top surface of the conveying frame, and two sets of hydraulic rods are fixedly installed on the top surface of the gantry. The moving part of the hydraulic rod penetrates through the gantry and is fixedly installed with a lifting frame, and the outer pipe is fixedly inserted into the lifting frame.

[0008] Further, the servo lifting and rotating mechanism includes two sets of sealing rings fixedly installed on the inner wall of the outer tube. A first servo motor is fixedly installed on the top surface of the upper sealing ring, and the output end of the first servo motor is fixedly connected to a threaded rod. Guide rods are fixedly installed on the opposite surfaces of the two sets of sealing rings. A movable ring is threadedly sleeved on the surface of the threaded rod, and the surface of the movable ring and the guide rod are slidably sleeved. The inner tube is movably inserted into the interior of the movable ring. A second servo motor is fixedly installed on the top surface of the movable ring, and the output end of the second servo motor penetrates through the movable ring and is fixedly installed with a first gear.

The limiting ring and the toothed ring are located on the upper and lower sides of the movable ring, and there is a gap between the toothed ring and the movable ring, and there is no connection relationship.

[0009] Further, the pitching adjustment assembly includes a mounting frame fixedly inserted at the bottom end of the inner tube. Two sets of rotating shafts are rotatably inserted on the surface of the mounting frame. Sprayer mounting seats are fixedly sleeved on the surfaces of the two sets of rotating shafts. Second gears are fixedly sleeved on the surfaces of the two sets of rotating shafts, and the two sets of second gears are meshed and installed. A third servo motor is fixedly installed on the surface of the mounting frame, and the output end of the third servo motor is fixedly connected to the end of one of the rotating shafts. A protective cover is fixedly installed on the surface of the mounting frame, and the third servo motor is located inside the protective cover.

[0010] Further, the air jetting mechanism includes an air nozzle fixedly inserted into the sprayer mounting seat. The input end of the air nozzle is fixedly connected to an air pipe. The air pipe and the inner tube are fixedly inserted inside, and a first air pump is arranged on the surface of the air pipe.

Detailed implementation manners

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows

[0021] The following, in combination with the accompanying drawings, details the technical solutions provided by each embodiment of the present invention

[0022] Refer to Figures 1 to 11As shown in the figure, an anti-corrosion storage tank lining spraying device provided by an embodiment of the present invention includes a conveying frame 1. A conveyor belt conveying mechanism 2 is arranged inside the conveying frame 1 to convey the anti-corrosion storage tank. A lifting mechanism 4 is arranged on the conveying frame 1. An outer pipe 5 is fixedly installed inside the movable part of the lifting mechanism 4. A servo lifting and rotating mechanism 6 is arranged inside the outer pipe 5. An inner pipe 7 is movably inserted into the movable part of the servo lifting and rotating mechanism 6. The inner pipe 7 is driven by the servo lifting and rotating mechanism 6 to move vertically and rotate. An elevation adjustment assembly 8 is fixedly installed at the bottom end of the inner pipe 7. Airflow injection mechanisms 9 and spraying mechanisms 10 are arranged on the two movable parts of the elevation adjustment assembly 8 and inside the inner pipe 7. The elevation adjustment assembly 8 is used to adjust the elevation angles of the airflow injection mechanisms 9 and spraying mechanisms 10 to be applicable to special-shaped anti-corrosion storage tanks.

[0023] It should be noted that when the inner pipe 7 is pulled out or inserted into the tank opening of the anti-corrosion storage tank, the elevation adjustment assembly 8 makes the airflow injection mechanisms 9 and spraying mechanisms 10 in a vertically downward state.

[0024] More specifically, connect the output pipe of the anti-corrosion paint supply tank to the connection end of the spraying mechanism 10. Horizontally convey the anti-corrosion storage tank to the lower part of the lifting mechanism 4 through the conveyor belt conveying mechanism 2. Drive the outer pipe 5 to move vertically downward through the lifting mechanism 4 so that the inner pipe 7 is inserted into the anti-corrosion storage tank. Drive the inner pipe 7, the elevation adjustment assembly 8, and the airflow injection mechanisms 9 and spraying mechanisms 10 on the elevation adjustment assembly 8 and the inner pipe 7 to rotate and move vertically inside the anti-corrosion storage tank through the servo lifting and rotating mechanism 6. Spray the anti-corrosion paint onto the inner wall of the anti-corrosion storage tank through the spraying mechanism 10. At the same time, spray out dry and heated air through the airflow injection mechanisms 9 to accelerate the drying efficiency of the paint. The evenness of the paint can be controlled by controlling the pressure of the airflow sprayed out by the airflow injection mechanisms 9. While spraying and drying the inside of the anti-corrosion storage tank, the elevation adjustment assembly 8 adjusts the elevation angles of the spray heads of the airflow injection mechanisms 9 and spraying mechanisms 10 to be able to spray-process the inner wall of the special-shaped anti-corrosion storage tank.

[0025] In some practical applications, a sealing ring plate 51 is fixedly sleeved on the surface of the bottom end of the outer pipe 5 for sealing the tank opening of the anti-corrosion storage tank. Two sets of symmetrically arranged fixing mechanisms 11 are fixedly installed on the edge of the sealing ring plate 51. An exhaust gas treatment mechanism 12 is arranged on the surface of the outer pipe 5 to filter the exhaust gas generated when spraying paint on the inner wall of the anti-corrosion storage tank.

[0026] More specifically, when the inner tube 7 is inserted into the anti-corrosion storage tank by the lifting mechanism 4, the sealing ring plate 51 on the surface of the outer tube 5 is closely attached to the end face of the tank opening of the anti-corrosion storage tank, thereby sealing the anti-corrosion storage tank and preventing the waste gas from overflowing during spraying. The fixing mechanism 11 further fixes the tank opening of the anti-corrosion storage tank. During operation, the waste gas treatment mechanism 12 filters the waste gas in the anti-corrosion storage tank to avoid the direct discharge of polluting gases, which is more environmentally friendly.

[0027] In some practical applications, the servo lifting and rotating mechanism 6 includes two groups of sealing rings 601 fixedly installed on the inner wall of the outer tube 5. A first servo motor 602 is fixedly installed on the top surface of the upper sealing ring 601, and the output end of the first servo motor 602 is fixedly connected to a threaded rod 603. Guide rods 604 are fixedly installed on the opposite surfaces of the two groups of sealing rings 601. A movable ring 605 is threadedly sleeved on the surface of the threaded rod 603, and the surface of the movable ring 605 and the guide rod 604 are slidably sleeved. The inner tube 7 is movably inserted into the interior of the movable ring 605. A second servo motor 606 is fixedly installed on the top surface of the movable ring 605, and the output end of the second servo motor 606 penetrates through the movable ring 605 and is fixedly installed with a first gear 607. A toothed ring 608 is fixedly sleeved on the surface of the inner tube 7, and the first gear 607 and the toothed ring 608 are meshed. A limiting ring 71 is fixedly sleeved on the surface of the inner tube 7. The limiting ring 71 and the toothed ring 608 are located on the upper and lower sides of the movable ring 605, and there is a gap between the toothed ring 608 and the movable ring 605 and no connection relationship.

[0028] More specifically, the first servo motor 602 drives the threaded rod 603 to rotate. Through the threaded sleeve of the movable ring 605 on the surface of the threaded rod 603, the movable ring 605 moves vertically along the surface of the guide rod 604, realizing the vertical movement of driving the inner tube 7, the pitching adjustment assembly 8, the air flow injection mechanism 9, and the spraying mechanism 10. The second servo motor 606 drives the first gear 607 to rotate. The meshing of the first gear 607 and the toothed ring 608 drives the toothed ring 608 and the inner tube 7, the pitching adjustment assembly 8, the air flow injection mechanism 9, and the spraying mechanism 10 to rotate. Through the servo lifting and rotating mechanism 6, the inner tube 7, the pitching adjustment assembly 8, the air flow injection mechanism 9, and the spraying mechanism 10 can rotate while moving vertically.

[0029] In some practical applications, the pitching adjustment assembly 8 includes a mounting bracket 801 fixedly inserted at the bottom end of the inner tube 7. Two sets of rotating shafts 802 are rotatably inserted on the surface of the mounting bracket 801. Spray head mounting seats 803 are fixedly sleeved on the surfaces of the two sets of rotating shafts 802. Second gears 804 are fixedly sleeved on the surfaces of the two sets of rotating shafts 802. The two sets of second gears 804 are meshed and installed. A third servo motor 805 is fixedly installed on the surface of the mounting bracket 801. The output end of the third servo motor 805 is fixedly connected to the end of one of the rotating shafts 802. A protective cover 806 is fixedly installed on the surface of the mounting bracket 801, and the third servo motor 805 is located inside the protective cover 806.

[0030] More specifically, the protective cover 806 located outside the third servo motor 805 protects the third servo motor 805. The third servo motor 805 drives one of the rotating shafts 802, the spray head mounting seat 803, and the second gear 804 to rotate. Through the meshing of the two sets of second gears 804, the other set of rotating shafts 802, the spray head mounting seat 803, and the second gear 804 are driven to rotate synchronously and in the opposite direction, so that the pitching angles of the air spray head 901 and the paint spray head 1001 can be adjusted.

[0031] In some practical applications, the air jetting mechanism 9 includes an air spray head 901 fixedly inserted in the spray head mounting seat 803. An air pipe 902 is fixedly connected to the input end of the air spray head 901. The air pipe 902 and the inner tube 7 are fixedly inserted inside. A first air pump 903 is arranged on the surface of the air pipe 902. A heating ring 904 is fixedly sleeved on the surface of the air pipe 902 for heating the incoming air. A filter net can be installed at the air inlet end of the air pipe 902 to filter impurities in the incoming air.

[0032] More specifically, the first air pump 903 allows external air to pass through the air pipe 902 to the air spray head 901. When the air enters, the heating ring 904 heats and dries the air. The dried hot air is discharged through the air spray head 901, thereby accelerating the drying of the paint in the anti-corrosion storage tank. By controlling the real-time power of the first air pump 903, the jet pressure of the air flow can be controlled, so the evenness of the paint on the inner wall of the anti-corrosion storage tank can be controlled.

[0033] In some practical applications, the spraying mechanism 10 includes a paint spray head 1001 fixedly installed. A feed pipe 1002 is fixedly connected to the input end of the paint spray head 1001. The feed pipe 1002 and the inner tube 7 are fixedly inserted inside. A liquid pump 1003 is arranged on the surface of the feed pipe 1002. The top end of the feed pipe 1002 is coaxially arranged with the inner tube 7. A right-angle connector 1004 is rotatably installed at the end of the feed pipe 1002.

[0034] More specifically, it is connected to the output pipe of the anti-corrosion paint supply tank through the right-angle connector 1004, and rotatably inserted into the feed pipe 1002 through the right-angle connector 1004, so as to avoid the knotting of the output pipe of the anti-corrosion paint supply tank when the inner pipe 7 rotates. The liquid pump 1003 is used to introduce the paint into the paint spray head 1001 through the feed pipe 1002 and the output pipe of the anti-corrosion paint supply tank, and the paint is sprayed out through the paint spray head 1001.

[0035] In some practical applications, the fixing mechanism 11 includes two groups of symmetrically arranged L-shaped side plates 1101 fixedly installed on the edge of the sealing ring plate 51. The end face of the L-shaped side plate 1101 is fixedly installed with an electric push rod 1102. The end of the electric push rod 1102 is fixedly connected with an arc-shaped clamping plate 1103, and the end face of the arc-shaped clamping plate 1103 is fixedly installed with a limiting rod 1104, and the limiting rod 1104 and the L-shaped side plate 1101 are inserted into the movable part.

[0036] More specifically, after the bottom surface of the sealing ring plate 51 fits with the end face of the anti-corrosion storage tank opening, the two electric push rods 1102 drive the arc-shaped clamping plates 1103 to approach each other respectively, so that the arc ends of the arc-shaped clamping plates 1103 fit with the surface of the anti-corrosion storage tank opening to fix the anti-corrosion storage tank. And the two arc-shaped clamping plates 1103 approach each other, so that the inner pipe 7 can be located at the center of the anti-corrosion storage tank, and the coating thickness sprayed on its inner wall can be uniform during spraying.

[0037] In some practical applications, the waste gas treatment mechanism 12 includes an exhaust pipe 1201 arranged on the surface of the outer pipe 5. The end of the exhaust pipe 1201 is fixedly connected with a second air pump 1202. The second air pump 1202 runs synchronously with the air flow injection mechanism 9. The output end of the second air pump 1202 is connected with a filter material box 1203, and the inside of the filter material box 1203 is filled with filter material. The filter material can be activated carbon, and the top cover of the filter material box 1203 is detachable, and the saturated filter material can be replaced regularly. And a metal net 1204 is arranged on the end face of the filter material box 1203.

[0038] More specifically, when the air flow injection mechanism 9 dries the paint inside the anti-corrosion storage tank, the second air pump 1202 is used to extract the polluted gas in the anti-corrosion storage tank into the filter material box 1203 through the exhaust pipe 1201. The filter material in the filter material box 1203 filters the harmful substances in the polluted gas, thereby avoiding the pollution of the air by the waste gas generated during spraying.

[0039] In some practical applications, two sets of correspondingly arranged photoelectric sensors 3 are inserted on the surface of the conveying rack 1, and the photoelectric sensors 3 are located below the gantry 401. When the anti-corrosion storage tank moves below the gantry 401, the anti-corrosion storage tank is located between the two sets of photoelectric sensors 3, so that the conveyor belt conveying mechanism 2 is stopped by the controller.

[0040] More specifically, through the two sets of photoelectric sensors 3 inserted correspondingly on both side walls of the conveying rack 1, when the conveyor belt conveying mechanism 2 drives the anti-corrosion storage tank to move below the gantry 401, the storage tank will block the light path of the photoelectric sensors 3, resulting in the inability to receive the light signal. After the controller receives the switch control signal output by the photoelectric sensors 3, it will perform signal processing and logical judgment. According to the preset control logic, the controller determines that the storage tank has reached the designated position, so that the conveyor belt conveying mechanism 2 stops operating.

[0041] In another embodiment, the air jetting mechanism 9 and the spraying mechanism 10 can also operate asynchronously. The servo lifting and rotating mechanism 6 drives the air jetting mechanism 9 and the spraying mechanism 10 to vertically move and rotate inside the anti-corrosion storage tank. Through the spraying mechanism 10, the inner wall of the anti-corrosion storage tank is first spray-processed, and then the paint on the inner wall of the anti-corrosion storage tank is dried by the air jetting mechanism 9. While drying the paint, the waste gas treatment mechanism 12 synchronously extracts the waste gas inside the anti-corrosion storage tank and filters it; in some special paint surfaces or special paint spraying processes, by controlling the size of the air flow ejected by the air jetting mechanism 9, it is only used to dry the paint surface.

[0042] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to be equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
