Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint storage, in particular to a long-term storage tank for water-based paint. Background Art

[0002] Water-based paint has excellent durability and non-stick properties, and it has good adaptability to material surfaces, strong coating adhesion, and is evenly and completely applied, so it is loved in all walks of life. However, the storage requirements for water-based paint are very strict, and it needs to be stored intact in a vacuum state. Long-term storage during the storage process will cause sediment in the water-based paint, and it will not be used completely during use, and there will be paint attached to the inside of the storage device. Most storage devices now usually use a discharge port on the top to pour out the material. This method of discharge is incomplete, and there is still residual material left in the barrel after discharge, which causes a waste of resources, and the sediment will be discharged together during the discharge process, and the sediment of the water-based paint cannot be mixed.

[0003] For example, the announcement number CN218950035U, "A water-based paint storage device", includes a storage tank body, a central column is provided inside the storage tank body, a first bevel gear is provided on the top of the central column, a rotating rod is movably installed on the top of the central column, and a second bevel gear is fixed to one end of the rotating rod, and multiple sets of fan blades are fixed to the bottom of the central column, a connecting shaft is fixed to the outer wall of the central column, and a splint is provided on the outer wall of the connecting shaft, and a scraper is fixed to the end of the splint away from the fixed shaft. However, due to the discharge, the bottom is tilted so that the water-based paint can flow down the inclined surface to discharge, and the water-based paint is relatively viscous, and the scraper can only scrape the side wall of the storage tank, and cannot scrape the inclined bottom surface. When discharging, there will still be a large amount of paint attached to the bottom surface that is difficult to discharge.

[0004] This case was created to solve the above problems. Utility Model Content

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is a long-term storage tank for water-based paint. By arranging a spiral plate and a scraper block in the tank body, the scraper block can scrape and clean the spiral plate and the inner wall of the tank body at the same time, and can effectively remove the adhered paint. At the same time, as the scraper block scrapes downward with the spiral plate, the scraper block itself also stirs the paint in the tank body.

[0019] The utility model is further described in detail below through the drawings and embodiments.

[0020] The utility model embodiment provides a long-term storage tank for water-based paint, such as Figure 1-3 As shown, it includes a tank body 1, a polygonal transmission shaft 2 is arranged inside the tank body 1, a stepper motor 3 is arranged on the top of the tank body 1, the output end of the stepper motor 3 is connected to the polygonal transmission shaft 2, a scraper block 4 is sleeved on the polygonal transmission shaft 2, the scraper block 4 can slide on the polygonal transmission shaft 2, a spiral plate 5 is arranged inside the tank body 1, the upper and lower ends of the spiral plate 5 are respectively connected to the top and bottom of the tank body 1, the scraper block 4 is slidably connected to the spiral plate 5, the width of the spiral plate 5 is smaller than the radius of the tank body 1, the lower end of the scraper block 4 is slidably connected to the spiral plate 5, and the end of the scraper block 4 away from the polygonal transmission shaft 2 is slidably connected to the inner wall of the tank body 1, so that the scraper block 4 can scrape and clean the paint adhered to the inner wall of the tank body 1 and the spiral plate 5 when rotating.

[0021] Reference Figure 1-2 , and also includes a spiral guide convex strip 6, the pitch of the spiral guide convex strip 6 is equal to the pitch of the spiral plate 5 and the number of spiral turns is also equal, the spiral guide convex strip 6 is arranged on the inner wall of the tank body 1, the end surface of the scraper block 4 away from the multi-faceted transmission shaft 2 is attached to the inner wall of the tank body 1, and the end surface of the scraper block 4 away from the multi-faceted transmission shaft 2 is provided with a limiting groove 7, and the limiting groove 7 is slidably connected with the spiral guide convex strip 6, the scraper block 4 is sleeved on the multi-faceted transmission shaft 2, and the connection between the scraper block 4 and the multi-faceted transmission shaft 2 is similar to a spline connection, so that the multi-faceted transmission shaft 2 is connected to the multi-faceted transmission shaft 2. The multi-faceted transmission shaft 2 can drive the scraper block 4 to rotate. At the same time, the limiting groove 7 and the spiral guide ridge 6 on the scraper block 4 are slidably connected. With the cooperation of the limiting groove 7 and the spiral guide ridge 6, when the scraper block 4 rotates with the multi-faceted transmission shaft 2, the spiral guide ridge 6 causes the scraper block 4 to slide downward at the same time. Since the pitch of the spiral guide ridge 6 is equal to the pitch of the spiral plate 5 and the number of spiral turns is also equal, the scraper block 4 is always slidably connected to the spiral plate 5 during the downward rotation, thereby completing the scraping and cleaning of the spiral plate 5.

[0022] A limit plate 8 is provided at the lower end of the polygonal transmission shaft 2 , and the setting of the limit plate 8 prevents the scraper block 4 from escaping from the polygonal transmission shaft 2 .

[0023] A discharge port 9 is provided at the bottom of the tank body 1, and the discharge port 9 is close to the junction of the spiral plate 5 and the bottom of the tank body 1. A vertical baffle 10 is provided between the last spiral layer of the spiral plate 5 and the bottom surface of the tank body 1. The baffle 10, the tank body 1 and the spiral plate 5 form a closed cavity. In order to prevent the cleaned paint from accumulating at the bottom of the tank body 1, a vertical baffle 10 is provided between the last spiral layer of the spiral plate 5 and the bottom surface of the tank body 1. The baffle 10 blocks the cleaned paint and prevents it from entering the area below the spiral plate 5, directly enclosing the area below the spiral plate 5 into a closed space, making it difficult for the paint to enter, thereby avoiding accumulation.

[0024] Reference Figure 2-3 The scraper block 4 is provided with a plurality of small holes 11. When the scraper block 4 rotates downward, the paint can pass through the small holes 11, which can reduce the resistance encountered by the scraper block 4. At the same time, the setting of the small holes 11 can also increase the stirring effect of the scraper block 4.
