Description

Technical Field

[0001] The invention relates to the technical field of paint stirring tank detection, and in particular to a detection device for the inner wall of a special paint stirring tank. Background Art

[0002] Special coating mixing tank is a container equipment specially designed for mixing, stirring, storing special coatings and other process processes. This equipment is widely used in chemical, building materials, coatings, pharmaceutical and other industries. Especially when it is necessary to handle high viscosity, easy to crystallize or special properties of coatings, special coating mixing tank is particularly important, so a detection device for the inner wall of special coating mixing tank is needed.

[0003] At present, after the use of special coating mixing tanks, cleaning equipment is used to clean the inside of the tank. Due to the long-term storage of coatings in some mixing tanks, a large amount of coatings will adhere to the inner wall of the tank. Even after the tank is cleaned, there will be residual coatings such as dots or small pieces on the inner wall of the tank that are difficult to be found and difficult to clean.

[0004] Moreover, other types of coatings may be added to the cleaned tank. If it is not cleaned thoroughly, the residual coatings may be mixed with it, which may affect the purity of the subsequent coatings. For special coatings, even tiny impurities may affect its performance.

[0005] Moreover, these residual paints will easily cause corrosion or wear to the tank body for a long time, thus forming potholes. Paints are easy to adhere to the potholes and are difficult to clean. Over time, the overall service life of the tank body will be reduced. Therefore, inspection is required after cleaning. For this purpose, a detection device for the inner wall of a special paint mixing tank is proposed. Summary of the invention

Universal rollers are provided on the bottom surfaces at both ends of the support slide 52. The two universal rollers correspond to the positions of the two arc-shaped slideways 5. The universal rollers are movably connected in the rolling grooves. A containing ring is provided on the support slide 52, and the paint bucket 6 is placed on the support slide 52. One end of the two arc-shaped slides 5 is fixed on the slide rod 13, which can facilitate the positioning of the arc-shaped slide 5 to avoid position deviation.

[0063] A test motor is installed on the second bracket 43 to act on the angle of the rotating sand slide 42. The driving rod 44 is connected to the output end of the test motor. The sand slide 42 is fixedly installed on the driving rod 44. The sand slide 42 includes a frame and a closing strip. A sand slide channel is formed between the frame and the closing strip. The sand slide channel is tightly attached to the inner wall of the paint bucket 6. A sand slide funnel 48 is inserted into the sand slide channel to facilitate the pouring of fine sand. The sand slide 42 is adapted to the inner wall of the paint bucket 6. Two fixed frame plates 46 are fixedly installed at the upper and lower ends of the driving rod 44. A plurality of adjustment rods 47 are rotatably connected between the fixed frame plates 46 to facilitate the pressure. The tightening strip 41 rotates, and the outer side of the adjusting rod 47 is fixed with a tightening strip 41. The tightening strip 41 is located on both sides of the sand sliding strip 42, and acts to press the closing strip against the inner wall of the paint bucket 6 to avoid gaps that cause the fine sand to flow away. A circular bottom block 45 is also installed on the bottom end of the driving rod 44, and docking slides are arranged on both sides of the circular bottom block 45. The docking slides are connected to the sand sliding channel, and the fine sand that slides down on both sides can be recovered separately for comparison. The circular bottom block 45 is connected to the discharge port of the paint bucket 6, and the outer side of the discharge port of the paint bucket 6 is threadedly connected with a partitioned collection box 61 for easy collection.

[0064] Working principle: the lifting plate 18 is controlled to rotate and descend again, so that the second bracket 43 moves to the specified position. At this time, the sand sliding bar 42 will move into the paint bucket 6, and then the adjustment rod 47 is rotated to press the pressing bar 41 on the outside of the sand sliding bar 42. At this time, the sand sliding funnel 48 is installed at the specified position, and the specified weight of fine sand is poured from the sand sliding funnel 48. The fine sand will flow in the sand sliding channel. If there are corroded pits in the paint bucket 6, the residual paint in the pits is difficult to remove, and the fine sand will adhere to the paint in the pits, and a large amount of fine sand will flow into the collection box. 61, at this time, the micro-rotor motor 161 is controlled to rotate, the first arc clamp 16 and the second arc clamp 24 will drive the paint bucket 6 to swing left and right, and the support slide 52 will support the paint bucket 6 to slide on the arc slide 5. At this time, the fine sand remaining at the bottom will be swung out in the sand sliding channel, and then the fine sand in the collection box 61 can be weighed, and the amount of fine sand loss can be measured to determine whether there are potholes with residual paint inside, and then the angle of the sand sliding bar 42 can be rotated to repeatedly test different positions to determine whether there is corrosion on the inner wall.

If the inner wall is not cleaned, the fine sand will directly adhere to the sticky paint and the paint in the holes. At this time, the paint bucket 6 is controlled to shake left and right again to completely discharge the fine sand for weighing. According to the change in the weight of the fine sand, this embodiment does not scrape the inner wall, which can directly reflect whether the paint on the inner wall is completely clean.
