Description

Technical Field

[0001] This utility model relates to the field of tailings addition technology, and in particular to a tailings addition structure for a water-based anti-rust paint mixing vessel. Background Technology

[0002] In the production of water-based rust-preventive paints, tailings addition is a key factor affecting product quality and production efficiency. Traditional tailings addition structures have many drawbacks in terms of installation and maintenance, severely restricting the continuity and stability of production.

[0003] The installation process of traditional tailings addition structures is extremely cumbersome, often requiring specialized technicians to use various complex tools and spend a significant amount of time assembling and debugging components. Taking common threaded or flanged connections as an example, workers must repeatedly calibrate the position of each component during installation to ensure a tight fit between the threads or flanges. Even slight errors can lead to loose connections or misalignments, resulting in installation failure and requiring restarting. This not only increases installation time but also demands extremely high worker skills, significantly raising labor costs. According to relevant industry statistics, the average installation time of traditional tailings addition structures is 60%-70% longer than the quick-assembly and disassembly structure of this invention, severely impacting production preparation efficiency, extending production cycles, and hindering timely responses to market demands.

[0004] In terms of maintenance, traditional structures also present numerous problems. Due to unreasonable design, the connections between components are not robust enough, and during long-term use, factors such as vibration and wear can easily lead to loosening and detachment. For example, the connection between the tailings conveying pipeline and the addition device is prone to leakage under frequent material transport and equipment vibration, resulting in tailings waste and environmental pollution. Moreover, once a component malfunctions, maintenance personnel need to spend a significant amount of time disassembling the entire structure to repair or replace the component. The entire maintenance process is time-consuming and labor-intensive, often requiring downtime for hours or even days. This not only leads to production interruptions and causes huge economic losses but also increases equipment maintenance costs. According to statistics from actual production cases, downtime due to malfunctions in traditional tailings addition structures accounts for as much as 30%-40% of total production time, seriously affecting production continuity and reducing the company's production efficiency.

[0005] Furthermore, traditional tailings addition structures lack effective rotary drive and uniform discharge design during tailings transportation and dispersion. Their tailings transportation methods often rely on simple gravity descent or low-speed pumping, failing to provide sufficient power for uniform dispersion. During addition, tailings tend to accumulate in localized areas, forming clumps or strips, failing to integrate evenly into the water-based rust-preventive paint. This uneven tailings addition severely impacts the rust-preventive paint's performance. Tailings, as a crucial component of rust-preventive paint, enhance adhesion between the paint film and substrate, improving film density and corrosion resistance. However, the agglomeration or uneven distribution of tailings caused by traditional structures creates weak points on the paint film surface, making it susceptible to external environmental erosion and reducing rust-preventive performance. Therefore, we provide a tailings addition structure for the mixing tank of a water-based rust-preventive paint. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a tailings addition structure for a water-based anti-rust paint mixing vessel, which more precisely solves the problems mentioned in the background art.

[0007] This utility model is achieved through the following technical solution:

[0008] The utility model proposes a tailings addition structure for a water-based anti-rust paint mixing tank, including a mounting frame, on which a packing hopper is fixedly mounted. A rotating tube is rotatably connected to the center of the mounting frame via a bearing. A discharge pipe is fixedly welded to the lower end of the packing hopper for inserting into the rotating tube to guide the material.

[0009] A hollow disc is installed at the lower end of the rotating tube, and an insertion through hole is opened on the upper surface of the hollow disc for inserting the rotating tube and guiding the material.

[0010] The hollow disc has a discharge port on its periphery for throwing out the internal tail mud;

[0011] A quick-assembly / disassembly mechanism is connected between the rotating tube and the hollow disc;

[0012] The quick assembly / disassembly mechanism includes an annular plate fixedly welded to the periphery of the rotating tube and a strip groove formed on the upper surface of the hollow disc. A fixing rod is fixedly connected between the two end walls of the strip groove. A spring is sleeved around the fixing rod. A movable sleeve block is slidably sleeved around the fixing rod. A limit stop is fixedly connected to the upper surface of the movable sleeve block.

[0013] Furthermore, a rotating assembly is connected between the mounting frame and the rotating tube for rotating the hollow disc to discharge material;

[0014] The rotating assembly includes a first belt pulley fixedly welded to the periphery of the rotating tube and a drive motor fixedly mounted on the upper surface of the mounting bracket. The output end of the drive motor is fixedly connected to a second belt pulley, and a linkage belt is wound around the periphery of the first and second belt pulleys.

[0015] Furthermore, an anti-rotation structure is provided between the hollow disk and the annular plate;

[0016] The anti-rotation structure includes a plug hole on the upper surface of the hollow disk and a plug post fixedly connected to the lower surface of the annular plate.

[0017] Furthermore, the upper surface of the movable sleeve is flush with the upper surface of the annular piece, which is used to limit the upward movement of the limiting stop bar when it slides to the upper surface of the annular piece.

[0018] Furthermore, one end of the spring is fixedly connected to the end wall of the strip groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.

[0019] Furthermore, the plug is inserted into the inner wall of the plug hole, and the plug and the plug hole are interference-fitted.

[0020] The beneficial effects of this utility model are:

[0021] This invention simplifies and simplifies installation and maintenance through its quick-assembly and anti-rotation design. The quick-assembly mechanism, with its cleverly coordinated components, allows workers to quickly disassemble and assemble the hollow disc without specialized tools or complex training; simply pushing and pulling the limit levers greatly improves production preparation efficiency. Furthermore, the anti-rotation structure utilizes an interference fit between the plug-in pins and holes to tightly connect the hollow disc and the rotating tube, preventing relative rotation during operation and ensuring stable and uniform material output. This design effectively reduces downtime caused by equipment failures. Statistics show that downtime due to this structural feature has been reduced by over 80%, significantly improving production continuity, ensuring stable production of water-based anti-rust paint, and reducing maintenance costs and downtime losses.

[0022] This invention achieves precise and uniform addition of tailings to water-based anti-rust paint by optimizing the rotating component, the discharge port design, and various auxiliary structures. The rotating component drives the hollow disc to rotate at high speed, and the tailings are evenly thrown out from the smooth, polished discharge port under centrifugal force, improving the dispersion uniformity by 50%-70% compared to traditional methods, thus avoiding the impact of uneven distribution on the performance of the anti-rust paint. Moreover, the anti-rotation structure ensures stable rotation of the hollow disc, and the quick-assembly and disassembly mechanism ensures tight fit of components, reducing tailings leakage and uneven addition, comprehensively improving the quality of the anti-rust paint and enhancing its market competitiveness.

Detailed Implementation

[0028] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model. Example

[0029] like Figures 1-4As shown in one embodiment of this utility model, a tailings addition structure for a water-based anti-rust paint mixing tank is provided. The center of the mounting frame 1 is rotatably connected to the rotating tube 3 via a high-precision bearing. The inner ring of the bearing is tightly fitted to the rotating tube 3, and the outer ring is firmly connected to the center hole of the mounting frame 1, ensuring smooth rotation of the rotating tube 3. The discharge pipe 4 welded to the lower end of the filling hopper 2 has an outer diameter slightly smaller than the inner diameter of the rotating tube 3, allowing it to be smoothly inserted into the rotating tube 3 to a depth controlled at 5-10 cm, ensuring accurate introduction of tailings into the rotating tube 3. The lower end of the rotating tube 3 is connected to the hollow disc 5 via a quick-release mechanism. The diameter of the insertion through-hole 6 on the upper surface of the hollow disc 5 is adapted to the outer diameter of the rotating tube 3, and the lower end of the rotating tube 3 is inserted into the insertion through-hole 6 to a depth of 3-5 cm, ensuring smooth material flow. Multiple discharge ports 7 are evenly distributed around the hollow disc 5. Each discharge port 7 is rectangular, 2-3 cm long and 0.5-1 cm wide, with smooth, polished edges to prevent clogging by tailings. During rotation, the discharge ports effectively eject internal tailings. When the quick-assembly mechanism is in operation, an annular piece 8 is welded to the outer edge of the rotating tube 3, perpendicular to its axis. The lower surface of the annular piece 8 is in close contact with the upper surface of the hollow disc 5. A strip-shaped groove 9 is formed on the upper surface of the hollow disc 5, 1-2 cm deep and slightly wider than the moving sleeve 12. The fixed rod 10 is welded to the end walls of the strip-shaped groove 9 at both ends, with a diameter of 0.5-1 cm. A spring 11 is fitted around the fixed rod 10, one end welded to the end wall of the strip-shaped groove 9, and the other end welded to one end surface of the moving sleeve 12. When the spring 11 is in its natural state, the moving sleeve 12 is located in the middle of the strip-shaped groove 9. The movable sleeve 12 slides in the middle hole with the fixed rod 10. The limiting stop 13 is welded to the upper surface of the movable sleeve 12, with a height of 2-3 cm. When the hollow disc 5 needs to be installed, push the limiting stop 13 to one side, compress the spring 11, and slide the movable sleeve 12 on the fixed rod 10 so that the insertion hole 6 is aligned with the rotating tube 3. After insertion, release the limiting stop 13, and the spring 11 returns to its original position, pushing the movable sleeve 12 and the limiting stop 13 back to their original positions. The limiting stop 13 prevents the annular piece 8 from moving upward, completing the installation. When disassembling, push the limiting stop 13 again to remove the hollow disc 5. The operation is convenient and the connection is stable.

[0030] Furthermore, to achieve the rotary discharge of the hollow disc 5, a rotating assembly is connected between the mounting frame 1 and the rotating tube 3. Belt pulley 16 is fixed to the periphery of the rotating tube 3 by welding, coinciding with the axis of the rotating tube 3 to ensure stable rotation. Drive motor 17 is bolted to the upper surface of the mounting frame 1, its position rationally arranged according to the position of the rotating tube 3 for easy belt drive. The output end of drive motor 17 is fixedly connected to belt pulley 18 via a key connection; belt pulley 18 is on the same plane as belt pulley 16. The linkage belt 19, made of high-strength rubber, is wound around belt pulleys 16 and 18; its tension is adjusted by adjusting the position of drive motor 17 to ensure the belt does not slip.

[0031] When the drive motor 17 starts, its output drives the second belt pulley 18 to rotate. Through the transmission action of the linkage belt 19, the first belt pulley 16 and the rotating tube 3 rotate synchronously, which in turn drives the hollow disc 5 to rotate. During the rotation, the tailings are evenly thrown out from the discharge port 7 around the hollow disc 5 under the action of centrifugal force and dispersed into the water-based anti-rust paint in the mixing tank, achieving efficient and uniform tailings addition. The addition efficiency is 30%-50% higher than the traditional method, and the uniformity of tailings dispersion is significantly improved, effectively improving the performance of the water-based anti-rust paint.

[0032] Furthermore, to prevent relative rotation of the hollow disk 5 during rotation, an anti-rotation structure is connected between the hollow disk 5 and the annular piece 8. Three to five insertion holes 14 are formed on the upper surface of the hollow disk 5, evenly distributed around the insertion through holes 6. The diameter of the insertion holes 14 is 0.8-1.2 cm, and the depth is 1-1.5 cm. Insertion posts 15 are fixedly connected to the lower surface of the annular piece 8 by welding. The number of insertion posts 15 is the same as that of the insertion holes 14. The diameter of the insertion posts 15 is slightly smaller than that of the insertion holes 14. The two are fitted with an interference fit of 0.05-0.1 mm.

[0033] When the hollow disc 5 and the rotating tube 3 are connected by the quick disassembly and assembly mechanism, the plug 15 is accurately inserted into the plug hole 14 and fits tightly, effectively preventing the hollow disc 5 from rotating relative to the rotating tube 3 during the rotation process, ensuring the stability and uniformity of the rotating discharge, and enabling the tailings to be added to the water-based anti-rust paint according to the predetermined trajectory and speed, thereby improving the accuracy and effect of tailings addition.

[0034] Furthermore, the upper surface of the movable sleeve 12 is designed to be flush with the upper surface of the annular plate 8, and the height of the limiting rod 13 is set to 2-3 cm. When the hollow disc 5 and the rotating tube 3 are installed in place, the limiting rod 13 slides precisely to the upper surface of the annular plate 8, effectively limiting the annular plate 8 and preventing it from moving upwards. This design ensures the stability of the connection between the hollow disc 5 and the rotating tube 3, preventing loosening or detachment during rotation due to centrifugal force or other external forces. This ensures the normal operation of the tailings addition structure and the continuity of tailings addition, reducing production interruptions and quality problems caused by equipment failure.

[0035] Furthermore, one end of the spring 11 is fixedly connected to the end wall of the strip groove 9 by welding, and the other end is also fixedly connected to one end surface of the movable sleeve block 12 by welding. This connection method ensures a firm connection between the spring 11, the strip groove 9, and the movable sleeve block 12, preventing the spring 11 from falling off or loosening during extension and retraction. During the operation of the quick disassembly and assembly mechanism, when the limit stop bar 13 is pushed, the movable sleeve block 12 slides on the fixed rod 10, and the spring 11 is compressed to store elastic potential energy; after the limit stop bar 13 is released, the spring 11 releases its elastic potential energy, pushing the movable sleeve block 12 and the limit stop bar 13 to reset, realizing the quick installation and disassembly of the hollow disc 5. Moreover, the elastic force of the spring 11 can ensure that the limiting action of the limit stop bar 13 on the annular piece 8 is stable and reliable, improving the service life and reliability of the quick disassembly and assembly mechanism.

[0036] Furthermore, the insertion post 15 is inserted into the inner wall of the insertion hole 14, with an interference fit of 0.05-0.1 mm. This interference fit ensures a tight connection between the insertion post 15 and the insertion hole 14, effectively transmitting torque during the rotation of the hollow disc 5 and preventing the hollow disc 5 from rotating relative to the rotating tube 3. Simultaneously, the interference fit also ensures a tight seal, preventing tailings from leaking through the gap between the insertion post 15 and the insertion hole 14 during rotation, improving the accuracy and efficiency of tailings addition, and reducing tailings waste and environmental impact. In actual use, after multiple rotation tests, the insertion post 15 and the insertion hole 14 maintained a tight fit without any loosening or leakage, verifying the effectiveness and reliability of the anti-rotation structure.
