Description

Technical Field

[0001] The invention relates to the technical field of stirred tanks, in particular to a stirred tank for preparing chromium-free anti-fingerprint liquid for galvanized plates and a preparation method thereof. Background Art

[0002] The research and development of anti-fingerprint liquid is very rapid, and the application scope of anti-fingerprint plates is gradually expanding. According to the chemical properties of the coating, anti-fingerprint treatment has gone through two stages: inorganic series membranes and organic series membranes. The organic series membranes can be divided into traditional and environmentally friendly types. Environmentally friendly organic series membranes are the mainstream and research focus of modern anti-fingerprint treatment. The key technology lies in the selection of chromium-free anti-fingerprint liquid. In the preparation process of chromium-free anti-fingerprint liquid, whether the stirring kettle can stir the anti-fingerprint liquid evenly has a great influence on the performance of subsequent products.

[0003] Traditional chrome-free fingerprint-resistant liquid stirring kettles use multiple stirring blades to continuously stir the mixed liquid in the kettle, but the mixed liquid will have small clumps, which will affect the mixing and stirring effect. At the same time, the mixed liquid is pushed toward the inner wall of the kettle due to its excessive viscosity, and the stirring blades cannot pull the mixed liquid close to the inner wall of the kettle, so that the liquid in the kettle is not completely stirred. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A stirring kettle for preparing chrome-free anti-fingerprint liquid for galvanized sheet, comprising a shell, a support is fixedly connected to the bottom of the shell, a motor is fixedly connected to the middle of the top of the shell, the output end of the motor passes through the shell and extends to the inside, a feed port is opened at the top of the shell, an exhaust port is opened at the top of the shell, and a cooling pipe is arranged inside the shell; A tank body, which provides a place for stirring and is arranged inside the shell; A stirring assembly, which is arranged inside the tank body and is fixedly connected to an output end of the motor; A defoaming component, which is fixedly connected to the stirring component and is located above the stirring component; The stirring assembly includes a rotating shaft, which is fixedly connected to the motor, a fixed plate is fixedly connected to the outer side of the rotating shaft, and the fixed plate is a U-shaped plate. A swivel is fixedly connected to the outer side of the rotating shaft, and a connecting rod is fixedly connected to the outer side of the swivel. The end of the connecting rod away from the swivel is fixedly connected to the open end of the fixed plate. The material is added to the interior of the tank through the feed port, and the motor is connected to an external power supply to work. The motor drives the rotating shaft to rotate, and the rotating shaft drives the fixed plate to rotate through the swivel and the connecting rod, so as to mix and stir the material in the tank. By setting a U-shaped fixed plate, the curved inner surface of the fixed plate can be used to guide the material to form a circulation, so as to avoid the material in the corners or sides of the stirring container. The edge of the material is accumulated, thereby improving the mixing efficiency and quality. At the same time, when the rotating shaft drives the fixed plate to rotate clockwise, the fixed plate drives the inclined plate to rotate. Due to the small agglomerates in the material mixing, under the action of centrifugal force, the small agglomerates are located on the inner wall of the tank body, and the inclined plate contacts the small agglomerates. The fully mixed material passes through the inclined plate through the square hole, and the small agglomerates move along the inclined plate to the inside of the roller and the tank body. At this time, the extrusion between the roller and the tank body breaks up the small agglomerates, thereby improving the material mixing effect. The outer side of the fixed plate is fixedly connected to the square plate, the side of the fixed plate away from the square plate is fixedly connected to the inclined plate, and the side of the fixed plate close to the tank body is rotatably connected to the roller.

[0005] Preferably, there are two connecting rods, which are symmetrically arranged with the rotating ring as the center, and the connecting rods are located inside the opening of the fixed plate. After the stirring is completed, the motor drives the rotating shaft to rotate counterclockwise, and the rotating shaft drives the fixed plate and the square plate to rotate. At this time, the square plate scrapes the inside of the tank body, and the material moves away from the inner wall of the tank body along the fixed plate and the inclined plate, effectively cleaning the inner wall of the tank body to prevent the material from remaining inside the tank body. There are two square plates, which are evenly arranged with the rotating shaft as the center, and a square hole is opened on the side of the inclined plate away from the fixed plate. A spiral plate is fixedly connected to the outside of the rotating shaft, and the spiral plate is located in the middle of the fixed plate. Extension rings are fixedly connected to both ends of the spiral plate, and the extension rings are sleeved on the outside of the rotating shaft.

[0006] Preferably, the defoaming component includes a fixing ring, which is rotatably connected to the outer side of the rotating shaft, the fixing ring is located above the fixing plate, and a fixing rod is fixedly connected to the outer side of the fixing ring. There are two fixing rods, and the two fixing rods are evenly distributed with the fixing ring as the center. During the stirring process, foam will be generated, and the motor drives the rotating shaft to rotate, and the rotating shaft drives the fixing rod to rotate through the fixing ring, and the fixing rod drives the trapezoidal block to rotate. At this time, the material enters the interior of the trapezoidal block through the open end of the trapezoidal block, and the inclined edge of the trapezoidal block is deformed, and the inclined edge of the trapezoidal block can contact with the round rod. During the rotation process, the trapezoidal block and the round rod are indirectly in contact, so that the trapezoidal block drives the fixed block to move up and down to pass through the interior of the fixed rod The material is defoamed, and then the material leaves the trapezoidal block through the trapezoidal groove and the material guide port on the fixed rod. The rotating shaft drives the spiral plate to rotate, so that the material at the bottom of the tank body moves upward, thereby fully defoaming the material inside the tank body and improving the product quality. The outer side of the fixed rod is fixedly connected with a trapezoidal block, the inclined side of the trapezoidal block is elastic, the middle part of the trapezoidal block is fixedly connected to the fixed rod, the middle part of the trapezoidal block is provided with a material guide port, the outer side of the fixed rod is provided with a trapezoidal groove, the trapezoidal groove penetrates the fixed rod, the outer side of the fixed rod is provided with a through hole, the through hole is connected to the middle part of the trapezoidal groove vertically, the side of the trapezoidal block close to the through hole is fixedly connected with a fixed block, and the bottom of the fixed block is set as a tip.

[0007] Preferably, the shell includes an outer shell, which is fixedly connected to the pillar, a sealing block is fixedly connected to the inner wall of the outer shell, an intermediate plate is fixedly connected to the inner wall of the outer shell, a connecting plate is fixedly connected to the bottom of the intermediate plate, the intermediate plate is toothed, and the intermediate plate is elastic. By utilizing the elastic properties of the intermediate plate, the tank body will vibrate during stirring, which may cause the cooling pipe to collide with other components or cause the cooling pipe itself to deform. The intermediate plate performs buffering and limiting on the cooling pipe to avoid this situation. The intermediate plate is located at the gap between the tank body and the outer shell, and the cooling pipe is located in the groove on the intermediate plate. A round rod is fixedly connected to the inside of the sealing block, and the round rod is located above the trapezoidal block. An extension tube is fixedly connected to the middle of the inner part of the outer shell, and the outer shell is connected to the middle part of the tank body through the extension tube.

[0008] Preferably, the limit assembly includes a rotating rod, which is fixedly connected to the rotating shaft. A cylinder is fixedly connected to the bottom of the rotating rod. A sliding groove is provided on the outer side of the cylinder. The motor drives the rotating shaft to rotate, so that the rotating shaft drives the rotating rod to rotate. When the rotating rod rotates clockwise, the rotating rod drives the positioning rod and the spring plate to rotate through the cylinder. At this time, the spring plate is located inside the inclined groove, and the spring plate and the inclined groove are mutually engaged, so that the rotating rod drives the round table to rotate. At this time, the material cannot be discharged from the tank body through the extension tube. When the rotating rod rotates counterclockwise, the rotating rod drives the positioning rod and the spring plate to rotate. The spring plate is compressed by force, so that the positioning rod rotates inside the circular groove, so that the protrusion slides inside the chute on the cylinder, so that the round table moves up and down, and then the material begins to be discharged indirectly to prevent the extension tube from being blocked. The outer side of the cylinder is rotatably connected to the round table, and the side of the round table close to the chute is fixedly connected with a protrusion.

The inclination direction of the spring plate is the same as that of the inclined groove, and the outer side of the round table is fixedly connected to a diverter plate.

[0009] A method for preparing chromium-free anti-fingerprint liquid for galvanized sheet comprises the following steps: S1, material addition, adding the material into the tank through the feed port; S2, mixing and stirring, the motor drives the rotating shaft to rotate, and the rotating shaft drives the fixed plate to rotate through the rotating ring and the connecting rod, thereby mixing and stirring the materials inside the tank; S3, defoaming treatment, the rotating shaft drives the fixed rod to rotate through the fixed ring, and the material enters the interior of the trapezoidal block through the open end of the trapezoidal block, so that the trapezoidal block drives the fixed block to move up and down to defoam the material passing through the interior of the fixed rod; S4, the material is discharged, the rotating rod rotates counterclockwise, causing the positioning rod to rotate inside the circular groove, causing the circular table to move up and down, and then the material begins to be discharged indirectly.

[0011] 2. The galvanized sheet chrome-free fingerprint-resistant liquid preparation stirring kettle drives the fixed plate and the square plate to rotate through the rotating shaft. At this time, the square plate scrapes the inside of the tank body, and the material moves away from the inner wall of the tank body along the fixed plate and the inclined plate, effectively cleaning the inner wall of the tank body and avoiding material residue inside the tank body.

[0012] 3.

A swivel 82 is fixedly connected to the outer side of the rotating shaft 81, and a connecting rod 83 is fixedly connected to the outer side of the swivel 82. The end of the connecting rod 83 away from the swivel 82 is fixedly connected to the open end of the fixed plate 84. The material is added to the interior of the tank body 7 through the feed inlet 4, and the motor 3 is connected to an external power supply to work. The motor 3 drives the rotating shaft 81 to rotate, and the rotating shaft 81 drives the fixed plate 84 to rotate through the swivel 82 and the connecting rod 83, so as to mix and stir the materials in the tank body 7. By setting a U-shaped fixed plate 84, the curved inner surface of the fixed plate 84 can be used to guide the material to form a circulation, so as to avoid the material from being stirred in the corner of the stirring container. The material is mixed with the material by the square hole 87 and the inclined plate 86, and the small agglomerates are moved along the inclined plate 86 to the inside of the drum 88 and the tank 7.

After the stirring is completed, the motor 3 drives the rotating shaft 81 to rotate counterclockwise, and the rotating shaft 81 drives the fixed plate 84 and the square plate 85 to rotate. At this time, the square plate 85 scrapes the inside of the tank body 7, and the material moves away from the inner wall of the tank body 7 along the fixed plate 84 and the inclined plate 86, effectively cleaning the inner wall of the tank body 7 to prevent the material from remaining inside the tank body 7. There are two square plates 85, and the two square plates 85 are evenly arranged with the rotating shaft 81 as the center.

A spiral plate 89 is fixedly connected to the outer side of the rotating shaft 81, and the spiral plate 89 is located in the middle of the fixed plate 84. The two ends of the spiral plate 89 are fixedly connected to extension rings 810, and the extension rings 810 are sleeved on the outer side of the rotating shaft 81.

[0019] The second embodiment is based on the first embodiment. Figures 5 and 6As shown, the defoaming component 9 includes a fixing ring 91, which is rotatably connected to the outer side of the rotating shaft 81. The fixing ring 91 is located above the fixing plate 84. A fixing rod 92 is fixedly connected to the outer side of the fixing ring 91. There are two fixing rods 92, which are evenly distributed around the fixing ring 91. During the stirring process, foam will be generated. The motor 3 drives the rotating shaft 81 to rotate, and the rotating shaft 81 drives the fixing rod 92 to rotate through the fixing ring 91. The fixing rod 92 drives the trapezoidal block 95 to rotate. At this time, the material enters the interior of the trapezoidal block 95 through the open end of the trapezoidal block 95, and the inclined edge of the trapezoidal block 95 is deformed. The inclined edge of the trapezoidal block 95 can contact the round rod 13. During the rotation process, the trapezoidal block 95 indirectly contacts the round rod 13, so that the trapezoidal block 95 drives the fixing block 96 to move up and down to pass through the fixing rod 92. The material at the bottom is defoamed, and then the material leaves the trapezoidal block 95 through the trapezoidal groove 93 and the guide port 97 on the fixed rod 92. The rotating shaft 81 drives the spiral plate 89 to rotate, so that the material at the bottom of the tank body 7 moves upward, thereby fully defoaming the material inside the tank body 7 to improve the product quality. The outer side of the fixed rod 92 is fixedly connected with a trapezoidal block 95, the inclined side of the trapezoidal block 95 is elastic, the middle part of the trapezoidal block 95 is fixedly connected to the fixed rod 92, and the guide port 97 is provided in the middle part of the trapezoidal block 95.

The intermediate plate 14 is toothed and elastic. By utilizing the elastic performance of the intermediate plate 14, the tank body 7 will vibrate during the stirring process, which may cause the cooling pipe 6 to collide with other components or cause the cooling pipe 6 itself to deform. The intermediate plate 14 buffers and limits the cooling pipe 6 to avoid this situation. The intermediate plate 14 is located at the gap between the tank body 7 and the outer shell 11, and the cooling pipe 6 is located inside the groove on the intermediate plate 14.

A sliding groove 173 is provided on the outer side of the cylinder 172. The motor 3 drives the rotating shaft 81 to rotate, so that the rotating shaft 81 drives the rotating rod 171 to rotate. When the rotating rod 171 rotates clockwise, the rotating rod 171 drives the positioning rod 177 and the spring plate 178 to rotate through the cylinder 172. At this time, the spring plate 178 is located inside the inclined groove 179, and the spring plate 178 and the inclined groove 179 are mutually engaged, so that the rotating rod 171 drives the round table 174 to rotate. At this time, the material cannot be discharged from the tank body 7 through the extension tube 16. When the rotating rod 171 rotates counterclockwise, the rotating rod 171 drives the positioning rod 177 and the spring plate 178 to rotate. The spring plate 178 is compressed by force, so that the positioning rod 177 rotates inside the circular groove 176, so that the protrusion 175 slides inside the slide groove 173 on the cylinder 172, and the table 174 moves up and down, and then the material begins to be indirectly discharged to prevent the extension tube 16 from being blocked. The outer side of the cylinder 172 is rotatably connected to the table 174, and the side of the table 174 close to the slide groove 173 is fixedly connected to the protrusion 175.

By setting a U-shaped fixed plate 84, the curved inner surface of the fixed plate 84 can be used to guide the material to form a circulation, so as to avoid the accumulation of the material in the corner or edge of the mixing container, thereby improving the mixing efficiency and quality. At the same time, when the rotating shaft 81 drives the fixed plate 84 to rotate clockwise, the fixed plate 84 drives the inclined plate 86 to rotate.

The fully mixed materials pass through the inclined plate 86 through the square hole 87, and the small agglomerates move along the inclined plate 86 to the inside of the roller 88 and the tank body 7. At this time, the extrusion between the roller 88 and the tank body 7 causes the small agglomerates to be broken up, thereby improving the effect of material mixing.

[0024] During the stirring process, foam will be generated, and the motor 3 drives the rotating shaft 81 to rotate. The rotating shaft 81 drives the fixing rod 92 to rotate through the fixing ring 91, and the fixing rod 92 drives the trapezoidal block 95 to rotate. At this time, the material enters the interior of the trapezoidal block 95 through the open end of the trapezoidal block 95, and the inclined edge of the trapezoidal block 95 is deformed. The inclined edge of the trapezoidal block 95 can contact the round rod 13. During the rotation process, the trapezoidal block 95 is indirectly in contact with the round rod 13, so that the trapezoidal block 95 drives the fixing block 96 to defoam the material passing through the inside of the fixing rod 92, and then the material leaves the trapezoidal block 95 through the trapezoidal groove 93 and the material guide port 97 on the fixing rod 92, and the rotating shaft 81 drives the spiral plate 89 to rotate, so that the material at the bottom of the tank body 7 moves upward, thereby fully defoaming the material inside the tank body 7.

When the rotating rod 171 rotates clockwise, the rotating rod 171 drives the positioning rod 177 and the spring plate 178 to rotate through the cylinder 172. At this time, the spring plate 178 is located inside the inclined groove 179, and the spring plate 178 and the inclined groove 179 are mutually engaged, so that the rotating rod 171 drives the round table 174 to rotate. At this time, the material cannot be discharged from the tank body 7 through the extension tube 16. When the rotating rod 171 rotates counterclockwise, the rotating rod 171 drives the positioning rod 177 and the spring plate 178 to rotate, and the spring plate 178 is compressed, so that the positioning rod 177 rotates inside the circular groove 176, so that the protrusion 175 slides inside the slide groove 173 on the cylinder 172, so that the round table 174 moves up and down, and then the material begins to be discharged indirectly.
