Technical Field

[0001] The utility model relates to the technical field of wastewater evaporation treatment, in particular to a high-speed reverse-curved crushing vane for a mechanical atomizing evaporator. Background Technique

[0002] The rotary atomization technology atomizes the liquid material into micron-sized droplets through a high-speed rotating atomization disk. Its core equipment is a rotary atomizer, that is, a high-speed motor drives the atomization disk to rotate at a high speed. The high-speed rotating atomization disk generates a strong centrifugal force, and the material is thrown out at a high speed through the nozzle of the atomization disk, so as to be atomized into droplets with a micron-level diameter. When it contacts with hot air, mass transfer and heat transfer occur between the two. Rotary atomizers are widely used in zero-emission of wastewater, flue gas desulfurization, and tail gas treatment of waste incineration plants, etc.

[0028] Embodiment 1

[0029] Please refer to Figure 1 - Figure 4 , as shown in the figure, a high-speed reverse-curved crushing vane for a mechanical atomization evaporator includes an upper atomization disc 1. A water inlet 2 is provided on the outer wall of the upper atomization disc 1. A motor 3 is installed on the outer wall of the upper atomization disc 1. A connecting shaft 5 is fixedly connected to one end outer wall of the motor 3. An installation component is assembled on the outer wall of the connecting shaft 5. A lower atomization disc 16 is connected to one end outer wall of the connecting shaft 5;

[0030] The installation component includes a top rod 4. The top rod 4 is installed on the surface of the connecting shaft 5. A clamping block 6 is rotatably connected to the inner wall of the connecting shaft 5. A spring piece 7 is fixedly connected to the inner wall of the connecting shaft 5. An impeller 8 is slidably connected to the outer wall of the connecting shaft 5. A clamping groove 9 is provided on the outer wall of the impeller 8. A spring 10 is connected to the inner wall of the connecting shaft 5. A top plate 11 is fixedly connected to the top outer wall of the spring 10, and the surface of the top plate 11 is connected to the top rod 4. A crushing component is assembled on the outer wall of the impeller 8.

[0031] During use, first, the impeller 8 is slidably connected to the connecting shaft 5, causing the impeller 8 to press against the surface of the clamping block 6. When the clamping block 6 is pressed, it will rotate on the surface of the connecting shaft 5 and press against the spring piece 7. When the impeller 8 continues to slide on the surface of the connecting shaft 5, when the card slot 9 and the clamping block 6 are on the same horizontal line, the spring piece 7, under the action of an external force, pushes the clamping block 6 to rotate on the surface of the connecting shaft 5, so that the clamping block 6 snaps into the inside of the card slot 9. At the same time, the ejector rod 4 will press against the top plate 11 and the spring 10, causing the spring 10 to contract inward. Then, the spring 10, under the action of the force, will generate an outward thrust, cooperating with the engagement between the clamping block 6 and the card slot 9, thus completing the limitation of the impeller 8. After that, the lower atomizing disc 16 is slidably connected to one end of the connecting shaft 5. Finally, the snap ring 18 is snap-fitted into the groove 17 on the surface of the connecting shaft 5, enabling the snap ring 18 to limit the lower atomizing disc 16, thereby fixing the lower atomizing disc 16 to the surface of the connecting shaft 5 and improving the overall usability of the device.

[0032] Refer to Figure 1 - Figure 5 , as shown in the figure, the crushing assembly includes vanes 12, which are installed on the surface of the impeller 8. A liquid crushing surface 13 is provided on the outer wall of the vanes 12, a highest convex blade cross-section 14 is provided on the outer wall of the vanes 12, and a back blade 15 is provided on the outer wall of the vanes 12. Through the design of the highest convex blade cross-section 14 and the back blade 15, the vanes 12 have a narrow rear and a wide front, and the middle part is concave downward, which is the most blade shape of the vanes 12 that conforms to the mechanical principle.

[0033] During use, first, the water pipe is connected to the water inlet 2 to inject sewage into the upper atomizing disc 1. At the same time, the motor 3 is started to drive the connecting shaft 5 and the impeller 8 to rotate. Through the high-speed rotation of multiple groups of vanes 12 provided on the surface of the impeller 8, the liquid crushing surface 13 on the surface of the vanes 12 breaks the sewage into micron-sized particulate small droplets, forming a water mist, and discharges it to the external air through the gap between the upper atomizing disc 1 and the lower atomizing disc 16 for evaporation, improving the overall usability of the device.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
