Description

Technical Field

[0001] This invention relates to the field of mixing equipment, and in particular to an intelligent mixing equipment for the preparation of zinc powder coatings. Background Technology

[0002] In the preparation of zinc powder coatings, zinc powder needs to be added to the coating components. Zinc powder is usually added directly, but in practice, it easily clumps, severely hindering dispersion. Currently, there is no good solution to this problem in the existing technology. Therefore, the inventors of this application, through in-depth research, have developed an intelligent mixing device for the preparation of zinc powder coatings. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent mixing device for the preparation of zinc powder coatings, which can achieve effective dispersion of zinc powder.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] An intelligent mixing device for preparing zinc powder coatings includes a tank, a stirring assembly, and a dispersing assembly. The stirring assembly includes a stirring motor, a stirring shaft, and stirring blades. The stirring motor is installed at the bottom of the tank. The stirring shaft is vertically arranged, with its lower end connected to the stirring motor and its upper end inserted into the tank. The stirring blades are mounted on the stirring shaft. The dispersing assembly includes a vibrating motor, a feeding trough, and multiple feeding pipes. The feeding trough is located at the top of the tank and is annular in shape, wider at the top and narrower at the bottom. The vibrating motor is mounted on the feeding trough. The upper ends of the multiple feeding pipes are connected to the bottom of the feeding trough, and their lower ends are inserted into the tank.

[0006] In a preferred embodiment, the dispersing component further includes a plurality of tapping plates, the ends of which are connected to and parallel to the stirring shaft and located below the feeding pipe, and the plurality of tapping plates are evenly distributed around the stirring shaft.

[0007] In a preferred embodiment, the dispersing component further includes a discharge ring, which is horizontally arranged and has a material distribution chamber inside. The bottom of the material distribution chamber has multiple feeding ports, and the material distribution chamber is connected to the lower ends of the multiple feeding tubes. The upper end of the striking plate has a first placement groove, and the first placement groove has a first elastic element. The first elastic element is connected to a first insert rod, and the first insert rod is connected to a sealing block. The sealing blocks on the multiple striking plates are arranged one-to-one with the positions of the multiple feeding ports.

[0008] In a preferred embodiment, the feeding port is provided with a spherical groove, and the sealing block is configured as a sphere that cooperates with the spherical groove.

[0009] In a preferred embodiment, the stirring shaft is provided with a second mounting groove corresponding to each of the plurality of striking plates. The second mounting groove is provided with a second elastic element, and the second elastic element is connected to a second insert rod, which is connected to the striking plate.

[0010] In a preferred embodiment, at least two second placement slots are provided.

[0011] In a preferred embodiment, both the first elastic element and the second elastic element are configured as springs.

[0012] In a preferred embodiment, the stirring blade includes a first blade and a second blade, both of which are configured as inclined semi-circular arcs.

[0013] In a preferred embodiment, the stirring shaft is provided with a first connecting rod and a second connecting rod, the first connecting rod being connected to the first blade and the second connecting rod being connected to the second blade.

[0014] In a preferred embodiment, the bottom of the tank is provided with multiple support legs.

[0015] Compared with the prior art, the present invention provides an intelligent mixing device for the preparation of zinc powder coatings. In its structural setting, the stirring shaft is driven to rotate by a stirring motor, and the rotation of the stirring shaft drives the rotation of the stirring blades, thereby realizing the mixing of materials in the tank. At the same time, zinc powder can be added into the tank through the feeding trough. The zinc powder enters into multiple feeding pipes under the action of the vibrating motor. After being dispersed by multiple feeding pipes, it enters the tank, avoiding the clumping phenomenon caused by the zinc powder being added too centrally. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0026] like Figures 1 to 6 As shown, an intelligent mixing device for preparing zinc powder coatings includes a tank 1, a stirring assembly, and a dispersing assembly. The stirring assembly includes a stirring motor, a stirring shaft 2, and stirring blades. The stirring motor is installed at the bottom of the tank 1. The stirring shaft 2 is vertically arranged, with its lower end connected to the stirring motor and its upper end inserted into the tank 1. The stirring blades are mounted on the stirring shaft 2. The dispersing assembly includes a vibrating motor 4, a feeding trough 5, and multiple feeding pipes 6. The feeding trough 5 is located at the top of the tank 1 and is annular with a shape that is larger at the top and smaller at the bottom. The vibrating motor 4 is mounted on the feeding trough 5. The upper ends of the multiple feeding pipes 6 are connected to the bottom of the feeding trough 5, and their lower ends are inserted into the tank 1.

[0027] In this embodiment, an intelligent mixing device for preparing zinc powder coatings is configured such that a stirring motor drives a stirring shaft 2 to rotate, which in turn drives the stirring blades to rotate, thereby mixing the materials in the tank 1. At the same time, zinc powder can be added into the tank 1 through the feeding trough 5. The zinc powder enters multiple feeding pipes 6 under the action of a vibrating motor 4, and after being dispersed by the multiple feeding pipes 6, it enters the tank 1, avoiding the clumping phenomenon caused by the zinc powder being added too centrally.

[0028] To further enhance the dispersion effect, the dispersion component also includes multiple tapping plates 7. The ends of the tapping plates 7 are connected to the stirring shaft 2 and are parallel to the stirring shaft 2, located below the feeding pipe 6. The multiple tapping plates 7 are evenly distributed circumferentially around the stirring shaft 2. As the stirring shaft 2 rotates, it drives the tapping plates 7 to rotate as well. During rotation, the tapping plates 7 tap the zinc powder fed from the feeding pipe 6, causing the zinc powder to disperse and further preventing clumping.

[0029] To effectively control the feeding process, the dispersing component also includes a discharge ring 14, which is horizontally arranged and has a material distribution chamber inside. The bottom of the material distribution chamber is provided with multiple feeding ports 15. The material distribution chamber is connected to the lower ends of the multiple feeding pipes 6. The upper end of the striking plate 7 is provided with a first placement groove 8. The first placement groove 8 is provided with a first elastic element 9. The first elastic element 9 is connected to a first insertion rod 10. The first insertion rod 10 is connected to a sealing block 11. The sealing blocks 11 provided on the multiple striking plates 7 are arranged one-to-one with the positions of the multiple feeding ports 15. After the sealing block 11 is set, when the stirring shaft 2 is stopped, the sealing block 11 seals the feeding port 15, so that the zinc powder cannot flow out from the feeding port 15. That is, the feeding port 15 is opened when the stirring shaft 2 rotates and closed when the stirring shaft 2 stops. This achieves the automatic opening and closing of the feeding port 15, ensuring that all the zinc powder fed from the feeding port 15 is fed in during the movement of the tapping plate 7 and is tapped by the tapping plate 7, thus achieving the dispersed feeding of zinc powder.

[0030] To ensure that the sealing block 11 accurately seals the feed inlet 15 when the machine stops, a spherical groove 16 is provided at the feed inlet 15, and the sealing block 11 is configured to mate with the spherical groove 16. When the stirring shaft 2 stops rotating, due to the interaction between the sealing block 11 and the spherical groove 16, the sealing block 11 enters the spherical groove 16, accurately sealing the feed inlet 15.

[0031] Furthermore, to avoid noise caused by the impact between the sealing block 11 and the edge of the spherical groove 16 during operation, the stirring shaft 2 is provided with a second mounting groove 3 corresponding to each of the plurality of striking plates 7. A second elastic element 12 is provided in the second mounting groove 3, and a second insert rod 13 is connected to the second elastic element 12, which in turn connects to the striking plate 7. Under this structural design, when the stirring shaft 2 starts rotating, due to the centripetal force, the striking plate 7 moves radially outward along the stirring shaft 2, causing the sealing block 11 to move out of the spherical groove 16. At this time, the sealing block 11 does not contact the discharge ring 14, thus preventing impact and noise. When the stirring shaft 2 stops rotating, it returns to its position under the action of the second elastic element 12, and the sealing block 11 re-enters the spherical groove 16, sealing the discharge port.

[0032] To ensure a stable setting of the striking plate 7, the second mounting slot 3 is provided with at least two slots.

[0033] Specifically, both the first elastic element 9 and the second elastic element 12 are configured as springs.

[0034] In order to achieve a good stirring and dispersing effect, the stirring blade includes a first blade 17 and a second blade 19, both of which are set as inclined semi-circular arcs.

[0035] In order to achieve a stable setting of the first blade 17 and the second blade 19, the stirring shaft 2 is provided with a first connecting rod 18 and a second connecting rod 20. The first connecting rod 18 is connected to the first blade 17, and the second connecting rod 20 is connected to the second blade 19.

[0036] To ensure the stable setting of the tank body 1, the bottom of the tank body 1 is provided with multiple support legs 21.
