Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology, and in particular to a mixing device for the production of heavy-duty anti-corrosion coatings. Background Technology

[0002] Heavy-duty anti-corrosion coatings are high-performance protective coatings designed specifically for extreme corrosive environments. They possess superior corrosion resistance, long-lasting protective life, and excellent mechanical properties, and are widely used for the protection of metal structures in harsh environments. However, during the mixing process of the raw materials for heavy metal anti-corrosion coatings, a co-solvent needs to be added to assist in the dissolution and mixing of the raw materials.

[0003] Existing heavy-duty anti-corrosion coating mixing processes often rely on manual addition of co-solvents multiple times, which is not only inefficient but also prone to uneven mixing. Furthermore, the amount of co-solvent added manually is difficult to control, thus affecting the quality of the coating. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device for the production of heavy-duty anti-corrosion coatings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixing device for producing heavy-duty anti-corrosion coatings includes a barrel body. A feed pipe is fixedly connected to one side of the barrel body near the top. An agitator for mixing raw materials is installed inside the barrel body. A material-holding funnel is fixedly connected to the top of the barrel body. A rotating hole is opened on the top of the barrel body, and a rotating shaft is rotatably connected to the rotating hole via a bearing. A turntable is fixedly connected to the bottom end of the rotating shaft. Two mounting ports are opened on the upper surface of the turntable. A discharge cylinder is fixedly connected to each of the two mounting ports, and one of the discharge cylinders is located directly below the material-holding funnel. A cover plate is provided at the bottom of each of the two discharge cylinders. A connecting rod is fixedly connected to one side of the cover plate. The connecting rod is connected to the discharge cylinder via a hinge. A notched ring is installed near the top of the barrel body via an installation component, and the connecting rod is located below the notched ring and in contact with the notched ring. A power component for driving the turntable to rotate intermittently is provided on the top outer wall of the barrel body.

[0007] As a further embodiment of this utility model, the power assembly includes a first motor, an L-shaped plate is fixedly connected to the top outer wall of the barrel, the first motor is fixedly connected to the top of the L-shaped plate, one end of the output shaft of the first motor passes through the L-shaped plate and is connected to a connecting shaft via a coupling, a missing gear is keyed to the bottom end of the connecting shaft, and a gear is keyed to the top of the rotating shaft, and the missing gear meshes with the gear.

[0008] As a further embodiment of this utility model, the mounting component is a fixing frame, which is fixedly connected to the inside of the barrel at a position below the turntable, and the missing ring is fixedly connected to the outside of the fixing frame.

[0009] As a further embodiment of this invention, sealing gaskets are fixedly connected to the upper surfaces of both the turntable and the cover plate.

[0010] As a further embodiment of this utility model, the stirring assembly includes a rotating shaft, which is rotatably connected to the inner wall of the bottom of the barrel via a bearing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0021] Reference Figures 1-3 A mixing device for producing heavy-duty anti-corrosion coatings includes a barrel 1. A feed pipe 19 is welded to one side of the barrel 1 near the top. The barrel 1 is equipped with an agitation assembly for mixing raw materials. The agitation assembly includes a rotating shaft 10, which is rotatably connected to the bottom inner wall of the barrel 1 via bearings. Multiple evenly distributed stirring rollers 13 are welded to the outside of the rotating shaft 10. A second motor 11 is fixed to the bottom outer wall of the barrel 1 by bolts. One end of the output shaft of the second motor 11 passes through the barrel 1 and is fixed to the rotating shaft 10. When mixing is required, the second motor 11 is started, which drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the stirring rollers 13 to rotate, so that the stirring rollers 13 agitate and mix the raw materials in the barrel 1.

[0022] In this invention, a material-holding funnel 2 is welded to the top of the barrel body 1. A rotating hole is provided at the top of the barrel body 1, and a rotating shaft 18 is rotatably connected to the rotating hole via a bearing. A turntable 14 is welded to the bottom end of the rotating shaft 18. Two mounting ports are provided on the upper surface of the turntable 14, and a discharge cylinder 7 is welded to each of the two mounting ports. One of the discharge cylinders 7 is located directly below the material-holding funnel 2. A cover plate 15 is provided at the bottom of both discharge cylinders 7. A connecting rod 16 is welded to one side of the cover plate 15. The connecting rod 16 is connected to the discharge cylinder 7 via a hinge. A missing ring 17 is installed near the top of the barrel body 1 via a mounting component, and the connecting rod 16 is located below the missing ring 17 and in contact with the missing ring 17. When a co-solvent needs to be added, the co-solvent is added into the material-holding funnel 2. At this time, the co-solvent in the material-holding funnel 2 will enter the discharge cylinder 7 located directly below the material-holding funnel 2, filling the discharge cylinder 7. The solvent is added, and then the rotating shaft 18 drives the turntable 14 to rotate. The turntable 14 drives the two feeding cylinders 7 to rotate. At this time, the sealing gasket on the turntable 14 will seal the feeding funnel 2 to prevent the solvent in the feeding funnel 2 from leaking. The feeding cylinder 7 will drive the cover plate 15 to rotate through the connecting rod 16. At this time, since the connecting rod 16 is in contact with the missing ring 17, when the connecting rod 16 on the cover plate 15 below the feeding cylinder 7 filled with solvent rotates to the notch of the missing ring 17, the cover plate 15 will rotate downward and open under the action of gravity, so that the solvent in the feeding cylinder 7 falls into the barrel 1. The cover plate 15 below the other feeding cylinder 7 will close the cover plate 15 through the contact of the connecting rod 16 and the missing ring 17 to seal the feeding cylinder 7, thereby realizing the automatic quantitative feeding of solvent without the need for manual feeding by the staff, ensuring the production quality of the coating.

[0023] In this utility model, the top outer wall of the barrel 1 is provided with a power component for driving the turntable 14 to rotate intermittently. The power component includes a first motor 3. An L-shaped plate is welded to the top outer wall of the barrel 1. The first motor 3 is fixed to the top of the L-shaped plate by bolts. One end of the output shaft of the first motor 3 passes through the L-shaped plate and is connected to a connecting shaft 4 through a coupling. A missing gear 5 is keyed to the bottom end of the connecting shaft 4. A gear 12 is keyed to the top of the rotating shaft 18. The missing gear 5 meshes with the gear 12. When the first motor 3 is started, the first motor 3 will drive the missing gear 5. The missing gear 5 will drive the gear 12 to rotate through meshing with the gear 12. The gear 12 will drive the rotating shaft 18 to rotate, thereby causing the turntable 14 to rotate.

[0024] When the two feeding cylinders 7 rotate 180 degrees, the feeding cylinder 7 with the cover plate 15 closed will rotate to the bottom of the material funnel 2, so that the flux in the material funnel 2 will enter the feeding cylinder 7 and fill the feeding cylinder 7. At the same time, the gear 5 will disengage from the gear 12. At this time, the first motor 3 will be turned off, so that the turntable 14 will stop rotating, thus facilitating the next quantitative feeding of the flux.

[0025] In this utility model, the mounting component is a fixing frame 8, which is fixed to the inside of the barrel 1 below the turntable 14 by bolts. The missing ring 17 is welded to the outside of the fixing frame 8. The upper surfaces of the turntable 14 and the cover plate 15 are both bonded with sealing gaskets. When the turntable 14 drives the two feeding cylinders 7 to rotate, the sealing gaskets on the turntable 14 will seal the material funnel 2 to prevent the solvent in the material funnel 2 from leaking. Two scrapers 9 that fit against the inner wall of the barrel 1 are welded to the outside of the rotating shaft 10. During the rotation of the rotating shaft 10, the scrapers 9 will rotate, thereby scraping and cleaning the raw materials on the barrel 1 to avoid waste of raw materials. A discharge pipe 6 is welded to the bottom of the barrel 1, and a valve is provided on the outside of the discharge pipe 6.

[0026] Working principle: When needed, the raw material is added into the container 1 through the feed pipe 19. When a co-solvent needs to be added, it is added into the feeding funnel 2. At this time, the co-solvent in the feeding funnel 2 will enter the discharge cylinder 7 located directly below the feeding funnel 2, filling the discharge cylinder 7 with co-solvent. Then, the first motor 3 is started, which drives the gear 5. The gear 5 meshes with the gear 12, which in turn drives the gear 12 to rotate. The gear 12 drives the turntable 14 to rotate through the rotating shaft 18. The turntable 14 drives the two discharge cylinders 7 to rotate. At this time, the sealing gasket on the turntable 14 will seal the feeding funnel 2, preventing the contents of the feeding funnel 2 from entering. If the co-solvent leaks, the feed cylinder 7 will rotate the cover plate 15 via the connecting rod 16. At this time, since the connecting rod 16 is in contact with the missing ring 17, when the connecting rod 16 on the cover plate 15 below the feed cylinder 7 filled with co-solvent rotates to the notch of the missing ring 17, the cover plate 15 will rotate downward and open under the action of gravity, so that the co-solvent in the feed cylinder 7 falls into the barrel 1. Meanwhile, the cover plate 15 below the other feed cylinder 7 will close and seal the feed cylinder 7 through the contact between the connecting rod 16 and the missing ring 17, thereby realizing automatic quantitative feeding of co-solvent without the need for manual feeding by the staff, ensuring the production quality of the coating.

[0027] When the two feeding cylinders 7 rotate 180 degrees, the feeding cylinder 7 with the cover plate 15 closed will rotate to directly below the material funnel 2, so that the flux in the material funnel 2 will enter the feeding cylinder 7 and fill the feeding cylinder 7. At the same time, the gear 5 will disengage from the gear 12, and the first motor 3 will be turned off, so that the turntable 14 will stop rotating, thus facilitating the next quantitative feeding of the flux.

[0028] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
