Description

Technical Field

[0001] The utility model relates to a microcapsule atomizer device. Background Art

[0002] In microcapsule granulation equipment, the feed liquid usually needs to be atomized in the main tower, and the feed liquid will enter the main tower in an atomized state. A microcapsule atomizer is needed. The microcapsule atomizer rotates through a motor, and the feed liquid is pumped to the feed pipe and enters the atomizing disk, and is atomized into droplets through the holes of the microcapsule atomizer. However, since most of the holes of the microcapsule atomizers are radial straight holes or oblique straight holes, the atomized droplets are not dense, the particles are hollow or apple-shaped, the droplets are uneven, and the particle size is uneven, resulting in the microcapsule particles being light in specific gravity, low in wear resistance, and uneven in size, resulting in poor product quality. Summary of the invention

[0003] The utility model aims to provide a microcapsule atomizer, the atomized droplets are dense, the particles are not hollow or apple-shaped, the droplets are uniform, and the particle size is uniform.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a microcapsule atomizer device, including a motor, a main shaft, a liquid inlet pipe, a shaft seat, an atomizing disk, a main tower and an air inlet, the main shaft is rotatably connected to the shaft seat through a motor drive, and the main shaft has an axial through hole, the atomizing disk is fixed to the inner end of the main shaft, the liquid inlet pipe passes through the axial through hole and extends into the atomizing disk, the air inlet is connected to the inner cavity of the main tower, and a plurality of conical holes are provided on the circumferential side wall of the atomizing disk.

[0005] Preferably, a pulley is provided on the output shaft of the motor, and a pulley is also provided on the main shaft. The two pulleys are connected by a belt transmission. The motor drives the pulley to rotate by driving, and after the pulley rotates, the main shaft is driven to rotate by the belt.

[0006] Preferably, the overflow port is arranged at the outer end of the shaft seat to prevent excessive liquid from affecting the effect.

[0007] Preferably, the oil receiving cup is close to the main shaft and fixedly connected to the shaft seat, which effectively prevents the oil on the main shaft from dripping into the main tower.

[0008] Preferably, the shaft seat is fixedly connected to the mounting seat via a mounting plate, and the mounting seat is fixedly connected to the main tower, so that the shaft seat remains stationary and only the main shaft rotates.

[0009] Preferably, the atomizing disk is cylindrical, and sealing plates are fixed at both ends. The liquid inlet pipe extends from the hole of the upper sealing plate, and the feed liquid is transported to the liquid inlet pipe by a pump and can directly enter the atomizing disk.

[0010] After adopting the above structure, the utility model has a plurality of conical holes on the circumferential side wall of the atomizing disk. The microcapsule atomizer rotates the motor 1500-3000 times, and the liquid is pumped to the liquid inlet pipe and enters the atomizing disk. After that, it is atomized into 50-1000um droplets through the conical holes in a radial tangential manner. The particle size is controlled by the aperture size and speed regulation, so that the liquid passing through has an extrusion process, and the air in the droplets is discharged. The atomized droplets are dense, and the particles are not hollow or apple-shaped. The droplets are uniform and the particle size is uniform. The size of the droplets can also be adjusted by controlling the flow rate, the aperture of the conical hole, the diameter and height of the atomizing disk. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0014] See also Figure 1 , 2 As shown, a microcapsule atomizer device includes a motor 1, a main shaft 3, a liquid inlet pipe 4, a shaft seat 6, an atomizing disk 8, a main tower 9 and an air inlet 10. The main tower 9 of the present application is a container for drying operations in the microcapsule granulation equipment. The shaft seat 6 is fixedly connected to the mounting seat 12 via a mounting plate 11, and the mounting seat 12 is fixedly connected to the main tower 9. In this embodiment, the shaft seat 6 and the mounting seat 12 are fixedly connected by bolts to keep the shaft seat 6 stationary. Ventilation is required during the rotation of the atomizing disk 8. An air inlet 10 is formed between the mounting plate 11 and the main tower 9 and is connected to the inner cavity of the main tower 9. The inner end of the main shaft 3 will extend into the main tower 9, and the main shaft 9 needs to rotate at a high speed. Therefore, the main shaft 3 is driven by the motor 1 to be rotatably connected to the shaft seat 6. The liquid needs to be transported to the atomizing disk 8 through the liquid inlet pipe 4, so the main shaft 3 has an axial through hole, and the atomizing disk 8 is fixed.

[0015] The liquid inlet pipe 4 is fixed at the inner end of the main shaft 3 , passes through the axial through hole and extends into the atomizing disk 8 , and a plurality of tapered holes 13 are provided on the circumferential side wall 14 of the atomizing disk 8 .

[0016] See also Figure 1As shown, a pulley 2 is provided on the output shaft of the motor 1, and a pulley 2 is also provided on the main shaft 3. The two pulleys 2 are connected by a belt drive. In this embodiment, when the device is started, the motor 1 drives the pulley 2 to rotate. After the pulley 2 rotates, the pulley 2 on the main shaft 3 is driven by the belt to rotate, thereby driving the main shaft 3 to rotate, and the main shaft 3 drives the atomizing disk 8 to rotate. The feed liquid is transported to the liquid inlet pipe 4 through the pump and enters the atomizing disk 8. During the rotation of the atomizing disk 8, the feed liquid is radially tangentially atomized into droplets through the conical hole 13.

[0017] See also Figure 1 As shown, the overflow port 5 is arranged at the outer end of the shaft seat 6. In this embodiment, after the liquid is pumped to the liquid inlet pipe 4 and enters the atomizing disk 13, if there is too much liquid, the excess liquid will overflow from the overflow port 5, effectively preventing the effect from being affected by too much liquid.

[0018] See also Figure 1 As shown, the oil receiving cup 7 is close to the main shaft 3 and fixedly connected to the shaft seat 6. In this embodiment, during the rotational connection between the main shaft 3 and the shaft seat 6, lubricating liquid needs to be frequently added to ensure smooth rotation and increase service life. In order to prevent the lubricating liquid from dripping into the main tower 9, the oil receiving cup 7 is provided. The lubricating liquid on the main shaft 3 will drip into the oil receiving cup 7 during rotation.

[0019] See also Figure 1 , 2 As shown, the atomizing disk 8 is cylindrical, and sealing plates 15 are fixed at both ends. The liquid inlet pipe 4 extends from the hole of the upper sealing plate 15. In this embodiment, the microcapsule atomizer is rotated by the motor 1, and the feed liquid is pumped to the liquid inlet pipe 4 and enters the atomizing disk 8. The feed liquid is radially tangentially atomized into 50-1000um droplets through the conical hole 13. By controlling the aperture size of the conical hole 13 and the speed control particle size, the conical hole 13 is designed so that the feed liquid passing through it has an extrusion process, and the air in the droplets is removed. The atomized droplets are dense, the particles are not hollow or apple-shaped, the droplets are uniform, and the particle size is uniform. The size of the droplets can also be adjusted by controlling the flow rate, the aperture of the conical hole 13, the diameter and height of the atomizing disk 8. Ensure that the finished product after drying meets the requirements.

[0020] The above is only a preferred embodiment of the present invention. It should be noted that for the common
