Description

Technical Field

[0001] This invention belongs to the field of silo anti-corrosion coating construction technology, specifically a silo structure anti-corrosion coating spraying device and its usage method. Background Technology

[0002] Silos are warehouses used to store bulk materials. Their structure mainly consists of the silo body, foundation, top, and feeding and discharging system. Silo structures are suitable for various applications, especially for grain storage warehouses, cement silos, granulation towers, coal and steel bunkers in thermal power plants, and chemical storage tanks, where anti-corrosion coatings are required on the inner and outer walls of the silos.

[0003] Currently, in silo anti-corrosion construction, especially on the inner walls of large silos, traditional manual spraying methods are still widely used. Workers are suspended in baskets or on scaffolding, using high-pressure airless sprayers to apply the coating by hand. This involves workers operating in a high-altitude, confined space, facing significant risks such as falls, being struck by objects, suffocation, and poisoning. The work relies entirely on the worker's skill and experience, making it difficult to maintain a constant spraying speed, distance, and angle. This easily leads to uneven coating thickness, missed areas, and runs, affecting the anti-corrosion effect. Setting up and dismantling scaffolding is time-consuming and labor-intensive, and workers, with limited stamina, need to take turns resting, resulting in a long overall construction period. Poor ventilation inside the silo leads to paint mist and volatile organic compounds (VOCs) permeating the air, seriously endangering the health of workers. Furthermore, the scattered paint causes waste and environmental pollution, failing to meet current needs. Summary of the Invention

The coating quality is inspected by the vision sensor 18 and the data is transmitted to the control system. S4. Control the cleaning scraper 15 to clean the second protective box 11. After cleaning, the cleaning scraper 15 rotates to a horizontal position. S5. The cleaning component 29 and the first scraper 34 are controlled to clean the cleaning scraper 15 and the cleaned impurities are guided into the collection box 28.

[0057] In step S1, during use, the device performs a system self-check to check whether the power supply, hydraulic system, and paint supply are normal. Anti-corrosion paint is added to the inside of the mixing paint tank 5, and the mixing structure is controlled to stir. On the device's built-in operation panel, the size of the silo, the designed spraying path (such as spiral ascent or descent), and the desired coating thickness are input. The mixing paint tank 5 moves on the ground via the drive device 1, and the distance fed back by the laser rangefinder 17 is used to adjust the position of the high-pressure airless spray gun 7 via the liftable mast 2, rotary table 3, and robotic arm 4. According to the instructions, it moves at a constant speed along the preset path. At the same time, the lifting and positioning system works together to precisely control the height of the spray arm and the distance between the spray gun and the inner wall, ensuring that it is always in the best spraying state.

[0058] In step S2, while moving and positioning, the feeding system is started. The high-pressure pump delivers the paint to the high-pressure airless spray gun 7 through the feeding pipeline 6. During the movement, the high-pressure airless spray gun 7 sprays the atomized paint evenly onto the inner wall of the silo.

[0059] In step S3, the data is transmitted to the control system. If uneven thickness or failure to reach the set value is detected, the control system will automatically adjust the moving speed of the high-pressure airless spray gun 7 or the paint flow rate to compensate, thereby achieving closed-loop quality control.

[0060] In step S4, the first drive motor 20 is started at regular intervals, and the two rotating rods 25 are controlled to rotate through the main gear 19, internal gear ring 21, external gear ring 23 and connecting shaft 24, so that the cleaning scraper 15 cleans the two second protective boxes 11, so as to avoid affecting the operation of the laser rangefinder sensor 17 and vision sensor 18, and so that the cleaning scraper 15 is reset to the horizontal state after cleaning.

[0061] In step S5, after the cleaning scraper 15 is reset, the second drive motor 32 is started, causing the moving part 30 and the first lead screw transmission structure 31 to cooperate in moving the cleaning part 29 to the end of the cleaning scraper 15, and causing the insert 46 to be inserted into the cleaning part 29, so that the two first scraper 34 move inside the cleaning part 29 and after the first scraper 34 is in contact with the cleaning scraper 15, the cleaning part 29 is controlled to move back and clean the impurities removed by the cleaning scraper 15. When the cleaning part 29 is reset into the cleaning box 16, the third drive motor 49 is started, and the second lead screw transmission structure 50 is controlled to drive the second scraper 35 to clean the first scraper 34 and the cleaning part 29, and the cleaned impurities are transported to the collection box 28.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
