Description

Technical Field

[0001] This utility model relates to the field of self-cleaning nano-coating preparation technology, and in particular to a mixing device for preparing self-cleaning nano-coatings. Background Technology

[0002] In the field of self-cleaning nanocoating preparation, the accuracy of raw material ratio and the uniformity of mixing directly determine the coating performance (such as self-cleaning efficiency, adhesion, and durability). Existing mixing devices for self-cleaning nanocoating preparation mostly adopt an intermittent operation mode of "first feeding, then stirring".

[0003] When solid nanoparticles, solvents, additives, and other raw materials are added to a mixing container all at once, they tend to accumulate at the bottom of the container due to gravity. Meanwhile, the stirring components (such as stirring rods or blades) are typically located in the middle or lower-middle part of the container, making it difficult for the upper layer of material (especially low-density liquids) to fully contact the stirring components during the initial stirring stage. To address this issue, a mixing device for preparing clean nanocoatings is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a proportioning device for preparing self-cleaning nano-coatings.

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

[0006] A self-cleaning nano-coating preparation mixing device includes a mixing chamber, a stirring shaft mounted on the mixing chamber via a mounting cover, multiple stirring rods mounted on the stirring shaft, two storage tanks mounted on the mounting cover via two feed pipes, each storage tank having a shielding cover and a lifting block, reciprocating screws mounted on each of the two feed pipes via a fixed plate, a drive motor connected to the stirring shaft mounted on the mounting cover via a support frame, both reciprocating screws being connected to the drive motor via a transmission mechanism, and movable frames threaded onto each of the two reciprocating screws via a limiting mechanism, with openings corresponding to the movable frames at the bottom of each of the two storage tanks.

[0007] Preferably, the transmission mechanism includes a drive gear mounted on the output shaft of the drive motor, and the reciprocating screw is provided with a transmission gear that meshes with the drive gear.

[0008] Preferably, the limiting mechanism includes a limiting rod mounted on a fixed plate, the limiting rod sliding through the movable frame.

[0009] Preferably, both feed pipes are provided with inclined sections, both storage bins are provided with inclined discharge ports, and the upper surface of the lifting block is inclined.

[0010] Preferably, one of the storage bins is equipped with a weighing device, and the other storage bin has a scale on its outer wall.

[0011] Preferably, the mixing chamber has an inverted cone shape inside, and the length of the multiple stirring rods decreases from top to bottom.

[0012] The beneficial effects of this utility model are:

[0013] 1. While the stirring shaft rotates at high speed, the reciprocating screw drives the movable frame to rise at low speed, so that the material can be gradually put in, avoiding the impact of pouring the material in all at once in traditional devices.

[0014] 2. The inverted cone-shaped mixing box has a narrower inner diameter at the bottom, which causes the material to converge towards the center during mixing, forming a vortex and enhancing the mixing effect.

[0015] 3. The drive motor controls both stirring and feeding simultaneously through the same transmission mechanism, reducing independent drive components, energy consumption, and equipment complexity. Attached Figure Description

[0021] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A self-cleaning nano-coating preparation mixing device includes a mixing chamber 1. A stirring shaft 15 is mounted on the mixing chamber 1 via a mounting cover 2. The mounting cover 2 is fixedly connected to the mixing chamber 1 using any existing method. Multiple stirring rods 16 are mounted on the stirring shaft 15. Two storage tanks 4 are mounted on the mounting cover 2 via two feed pipes 3. The feed pipes 3 are made of rigid material and can support the storage tanks 4 and other components. The number of storage tanks 4 and other components can be determined according to actual needs. Each storage tank 4 is equipped with a shielding cover 5 and a lifting block 17. The shielding cover 5 is movably connected to the storage tank 4 for easy removal and addition of materials. Both feed pipes 3 are equipped with reciprocating screws 10 via fixed plates 7. The mounting cover 2 is equipped with a drive motor 9 connected to the stirring shaft 15 via a support frame 8. Both reciprocating screws 10 are connected to the drive motor 9 via a transmission mechanism. Both reciprocating screws 10 are threaded with movable frames 12 via a limiting mechanism. The bottom of both storage boxes 4 is provided with openings corresponding to the movable frames 12.

[0023] The transmission mechanism includes a drive gear 13 mounted on the output shaft of the drive motor 9, and a transmission gear 14 meshing with the drive gear 13 on the reciprocating screw 10. As shown in the figure, the drive gear 13 is smaller and the transmission gear 14 is larger, which can play a role in speed reduction. The stirring shaft 15 rotates faster to ensure the stirring effect, while the reciprocating screw 10 rotates slower to ensure that the movable frame 12 rises and falls slowly.

[0024] After all the material in the storage bin 4 is discharged, the mixing shaft 15 and other components continue to operate to mix, and the lifting block 17 and other components continue to rise and fall without affecting the operation of the equipment.

[0025] The limiting mechanism includes a limiting rod 11 mounted on the fixed plate 7, which slides through the movable frame 12. The limiting rod 11 limits the movable frame 12, preventing it from rotating with the reciprocating screw 10.

[0026] Both feed pipes 3 are equipped with inclined sections, and both storage bins 4 are equipped with inclined discharge ports. The upper surface of the lifting block 17 is also inclined. The inclined design facilitates material discharge and allows the material to smoothly enter the mixing bin 1.

[0027] One of the storage bins 4 is equipped with a weighing device 18, and the other storage bin 4 has a scale 6 on its outer wall. The weighing device 18 is connected to an external display device using Bluetooth technology, which is in the prior art, so that the weight of the material inside can be determined, and the scale 6 can be used to determine the amount of liquid inside.

[0028] The interior of the mixing chamber 1 is inverted cone-shaped, with multiple stirring rods 16 decreasing in length from top to bottom. This design ensures effective mixing.

[0029] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0030] In use, after the drive motor 9 starts, it drives the transmission gear 14 to rotate via the drive gear 13, which in turn drives the reciprocating screw 10 to rotate. Since the drive gear 13 is smaller than the transmission gear 14, a speed reduction effect is achieved, causing the stirring shaft 15 to rotate at high speed (driving the stirring rod 16 to stir), while the reciprocating screw 10 rotates at low speed. As the reciprocating screw 10 rotates, the movable frame 12 slowly rises along the screw axis under the constraint of the limit rod 11. When the movable frame 12 rises, it can drive the lifting block 17 to rise, sending the material in the storage tank 4 into the mixing tank 1 through the discharge port and the feed pipe 3. The high-speed rotating stirring shaft 15 drives the stirring rod 16 (decreasing in length from top to bottom) to stir the material in the mixing tank 1. The interior of the mixing tank 1 is inverted conical, causing the material to flow centripetally due to the cone surface during stirring, which, combined with the shearing action of the stirring rod 16, achieves uniform mixing.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
