Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, the present embodiment provides a magnetic suspension high-speed rotary atomizer, which includes a slurry inlet pipe 1A, a slurry inlet pipe 1B, a liquid distributor 2, an atomizing disc 3 and a motor 4; the number of the slurry inlet pipes can be changed according to specific conditions, and the motor 4 is a magnetic suspension high-speed motor.

The slurry inlet pipe 1A and the slurry inlet pipe 1B are arranged at the top of the liquid separator 2, slurry is led into the liquid separator 2, and a slurry inlet pipe 11A and a slurry inlet pipe 11B are correspondingly arranged at the inlet of the slurry inlet pipe. Referring to fig. 4, the liquid separator 2 includes a liquid separator main body composed of an inner ring 21 and an outer ring 22, and a rotary tooth 23 installed between the inner ring 21 and the outer ring 22 for uniformly distributing the slurry, wherein a channel for circulating the slurry is formed between the inner ring 21 and the outer ring 22, and the slurry flows from top to bottom, and is uniformly distributed in the whole annular surface of the lower portion of the liquid separator under the action of the rotary tooth 23. Referring to fig. 5, the specific structure of the spiral teeth 23 can guide slurry flowing from top to bottom to form a circular flow at the bottom, thereby achieving the effect of uniform distribution. It is worth mentioning that the center of the inner ring 21 is used for the motor shaft 41 of the motor to pass through, and the inner ring 21 also has an isolation effect to prevent the slurry from directly contacting the motor shaft 41 rotating at high speed to splash. The bottom of the liquid distributor 2 extends into the atomizing disc 3 to guide the slurry into the atomizing disc 3. Atomizing disk 3 is driven by the motor and is rotated, and atomizing disk 3's week side is provided with nozzle 31, and the thick liquid receives centrifugal action, reaches the atomizing effect of thick liquid from the nozzle 31 blowout of atomizing disk 3 week side.

Referring to fig. 3 and 4, in order to realize connection between the motor 4 and the atomizing disk 3, a tapered section 42 is disposed at a front end of a motor shaft 41 of the motor 4, a tapered hole 32 for sleeving the tapered section 42 is disposed at a center of the atomizing disk 3, a flange nut 7 and a cap nut 6 are disposed at a front end of the tapered section, and the flange nut 7 and the cap nut 6 have the same rotation direction as the motor, so as to ensure sealing performance at a contact position of the cap nut 6 and the atomizing disk 3. The atomizing disk 3 is sleeved on the tapered section 42, the flange nut 7 is screwed in, the cap nut 6 is screwed in, and the atomizing disk 3 is firmly fixed on the motor shaft 41 and can rotate according to the rotation of the motor shaft 41. And the screw thread direction of the cap nut 6 is the same as the rotating direction of the motor, so that the loosening of the atomizing disk is prevented when the atomizer rotates at a high speed. The front end of the conical section 42 is sealed by the cap-shaped nut 6, so that the influence of oxidation and corrosion on the service life caused by long-time air contact is avoided.

Referring to fig. 4 and 6, an arc surface 33 is disposed in the atomizing disk 3, the arc surface 33 is curved from the center of the top of the atomizing disk 3 to the bottom edge, and when the slurry enters the atomizing disk from the bottom of the liquid distributor 2, the slurry is guided to the nozzle along the arc surface, so that the slurry is prevented from directly impacting the bottom of the atomizing disk 3 and losing a part of kinetic energy, and the existence of the arc surface 33 makes the atomizing effect better.

Referring to fig. 1 and fig. 3, in order to prevent dust or oil gas from polluting the magnetic suspension motor, the present embodiment further includes a protective cover 5, and the protective cover 5 is disposed outside the motor 4 and the slurry inlet pipe 1A and the slurry inlet pipe 1B. The outer surface of the protective cover 5 is provided with a support flange 51 for mounting of the atomizer. Meanwhile, in order to prevent the atomizer from directly contacting the mounting support with high temperature, the support flange 51 is provided with a damping rubber block 52 on the downward side, and the damping rubber block 52 can play a role in buffering, absorbing vibration and isolating high temperature.
