[0030] Please refer to Figures 1 to 4 This utility model discloses a high-efficiency aerosol coating device 100, comprising a frame 10, a mixing tank 20, and a feeding assembly 30. The mixing tank 20 is mounted on the frame 10. The feeding assembly 30 includes a slide plate 31 and multiple nozzles 32. The slide plate 31 is slidably mounted on the frame 10. One end of each nozzle 32 is mounted on the slide plate 31, and the other end passes through the mixing tank 20. Each nozzle 32 slides synchronously onto the mixing tank 20 as the slide plate 31 slides. The nozzles 32 are used to spray liquid and heated gas into the mixing tank 20. This high-efficiency aerosol coating device 100 sprays liquid and heated gas into the mixing tank 20 through the nozzles 32. The liquid is heated and atomized, causing the material in the mixing tank 20 to mix and coat with the liquid. Because each nozzle 32 slides synchronously onto the mixing tank 20 as the slide plate 31 slides, the coating is uniform, improving the coating efficiency and production capacity of the material.

Furthermore, the feeding assembly 30 also includes an air supply pipe 39, one end of which is connected to an air supply unit and the other end of which is connected to a nozzle 32.

[0034] like Figure 3 and Figure 4 As shown, the high-efficiency aerosol coating device 100 also includes a conveying assembly 40, which includes a support plate 41, a filter element 42, a cover plate 43, an air blowing pipe 44, and an air storage tank 45. The support plate 41 is detachably installed at one end of the circulation chamber 23. Optionally, the support plate 41 has through holes.

Optionally, the air blowing pipe 44 has multiple air holes, and the air holes are arranged one-to-one with the filter element 42. Air is blown from the air storage tank 45 towards the air blowing pipe 44, and the airflow blows towards the filter element 42 through the air holes, thereby blowing off the material on the filter element 42 and preventing the material from sticking to the filter element 42.

[0035] In one embodiment, the conveying assembly 40 further includes a handle 46, which is mounted on the support plate 41; the handle 46 facilitates the placement and removal of the support plate 41 and the filter element 42.

One end of the circulation pipe 54 is connected to the fan 53, and the other end is connected to the fixed base 21. Gas is input into the fixed base 21 through the inlet pipe 51, and the gas is blown towards the air flotation plate 26 to prevent material from accumulating on the air flotation plate 26. Through the cooperation of the return pipe 52, the fan 53, and the circulation pipe 54, the gas in the cover plate 43 is returned to the fixed base 21. In one embodiment, the carrier gas assembly 50 further includes a flow controller 55 and a pressure regulator 56. Both the pressure regulator 56 and the flow controller 55 are installed on the air inlet pipe 51, and the pressure regulator 56 is installed between the flow controller 55 and the air supply unit. The flow controller 55 precisely controls the ventilation volume of the covering, thereby improving the covering accuracy.

[0037] In one embodiment, the carrier gas assembly 50 further includes a first sensor 57, a second sensor 58, a pressure block 59, and a third sensor 59a. The first sensor 57 is mounted on the fixed base 21 and is used to detect the air pressure of the fixed base 21. The second sensor 58 is mounted on the cover plate 43. The pressure block 59 is used to cover the through hole. One end of the pressure block 59 is connected to the through hole, and the other end is inserted into the cover plate 43. The pressure block 59 is set corresponding to the second sensor 58. The airflow in the circulation chamber 23 enters the pressure block 59 through the through hole and then enters the cover plate 43 so that the second sensor 58 can detect the air pressure in the circulation chamber 23. Optionally, the pressure block 59 is a suction cup. The third sensor 59a is mounted on the cover plate 43 and is used to detect the air pressure in the space enclosed by the cover plate 43 and the support plate 41. Furthermore, the air carrier assembly 50 also includes an elastic element (not shown), one end of which abuts against the pressure block 59 and the other end of which abuts against the cover plate 43, so that the pressure block 59 is pressed tightly against the support plate 41 by the elastic element; optionally, the elastic element is a spring.

[0038] like Figure 4 As shown, the high-efficiency aerosol coating device 100 also includes a stirring assembly 60, which includes a pad 61, a rotating shaft 62, a turntable 63, protruding ribs 64, and a stirring power element 65. One end of the pad 61 abuts against the fixed seat 21, and the other end abuts against the air flotation plate 26. The rotating shaft 62 passes through the fixed seat 21, the pad 61, and the air flotation plate 26 in sequence, and the turntable 63 is installed on the rotating shaft 62. Optionally, the pad 61 is provided with a plurality of slots communicating with the air flotation plate 26, and the turntable 63 is provided with a plurality of through holes 630 communicating with the air flotation plate 26. There are a plurality of protruding ribs 64, each protruding from the end of the turntable 63 away from the air flotation plate 26. Optionally, the cross-section of the protruding rib 64 is trapezoidal. A stirring power element 65 is mounted on a fixed base 21 and is used to drive the rotating shaft 62 to rotate. The rotating shaft 62, driven by the stirring power element 65, causes the turntable 63 and the ribs 64 to rotate synchronously, thereby stirring the material. Furthermore, a negative pressure is created near the turntable 63. The stirring assembly 60 also includes a bearing (not shown) and an oil seal 66. The bearing is mounted on a pad 61, and the oil seal 66 is mounted on the air flotation plate 26. The rotating shaft 62 passes through the bearing and the oil seal 66.

[0039] In operation, the valve of the feed pipe 24 is opened, while the valves of the discharge pipe 25 and the circulation pipe 54 are closed. The blower 53 starts working, and the material is drawn into the mixing tank 20 through the feed pipe 24 until the predetermined amount of material is drawn into the mixing tank 20. At this point, the valve of the feed pipe 24 is closed, and the valve of the circulation pipe 54 is opened. Next, the heated gas enters the fixed base 21 through the air inlet pipe 51, and then enters the coating chamber 22 through the air flotation plate 26 and the turntable 63, allowing the material to flow fully and preventing the material from accumulating on the air flotation plate 26 and the turntable 63. Then, the liquid and the heated gas enter the nozzle 32 respectively, and are then injected into the mixing tank 20. The high temperature atomizes the liquid, achieving mixing of the material and the liquid. At the same time, the slide plate 31 drives the nozzle 32 to slide back and forth at a uniform speed, and the stirring power element 65 drives the rotating shaft 62 to rotate. The rotating shaft 62 drives the turntable 63 and the rib 64 to rotate, allowing the material to flow fully, and a negative pressure zone is formed near the rotating shaft 62. Air is continuously introduced through the air inlet pipe 51, and the nozzle 32 sprays atomized liquid upwards, forcing the material to flow continuously upwards. The material enters the circulation chamber 23 from the coating chamber 22. Due to the negative pressure zone formed near the rotating shaft 62, the material flows back from the circulation chamber 23 to the coating chamber 22, forming a circulating mixture to ensure that the material and liquid are fully mixed and coated. The circulating mixture continues until the predetermined mixing time. Finally, the valve of the discharge pipe 25 opens, and the mixed and coated product is discharged into the material tank through the discharge pipe 25.

[0040] This high-efficiency aerosol coating device 100 accurately weighs the amount of liquid required for coating using a weighing device 35, and controls the flow rate of gas entering the mixing tank 20 using a flow controller 55 to improve coating accuracy. Multiple nozzles 32 are driven to slide back and forth at a uniform speed by a sliding plate 31, and the rotating shaft 62 drives the turntable 63 and the ribs 64 to rotate, improving coating efficiency and production capacity, and making the coating more uniform. The fan 53 causes the gas in the mixing tank 20 to enter the circulation pipe 54 through the return pipe 52 and then return to the mixing tank 20, realizing gas circulation, reducing gas consumption, reducing costs, and saving energy.

[0041] The high-efficiency aerosol coating device 100 of this invention sprays liquid and heated gas into the mixing tank 20 through nozzles 32. The liquid is heated and atomized, so that the material in the mixing tank 20 is mixed and coated with the liquid. As each nozzle 32 slides synchronously in the mixing tank 20 with the sliding plate 31, the coating is uniform, improving the coating efficiency and production capacity of the material.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
