Embodiment Construction

[0019] The structure of the internal mixing atomizing nozzle device of the present invention will be described with reference to the drawings and embodiments.

[0020] The structure of the internal mixing atomizing nozzle device of the present invention is: the nozzle device includes a mixing chamber 1, and an air inlet pipe 4 is provided on the side wall of the mixing chamber 1; An air flow cover 3 is sheathed on the outside of the tube 2 . The outer surface of the injection pipe 2 and the inner surface of the airflow cover 3 form a high-speed airflow chamber, and the outlet of the airflow cover 3 is in the same direction as the outlet of the injection pipe 2 and slightly exceeds the outlet of the injection pipe 2, forming an annular outlet of the airflow chamber that shrinks towards the center. The other end of the airflow cover 3 is provided with an inlet to connect compressed air. The air intake direction of the airflow cover 3 enters in a tangential direction opposite to...

Abstract

The invention provides an inside-mixing atomizing nozzle device. The nozzle device comprises a mixing cavity, the side wall of the mixing cavity is provided with an air inlet pipe, the outlet of the mixing cavity is provided with a spray pipe, and an airflow cover is sleeved outside the spray pipe. The inside-mixing atomizing nozzle device has the advantages of dual effects of airflow atomizing and airflow impacting, so that materials are blown away and atomized by high-speed airflow to form airflow mixed mist to rotate inside the cavity at a high speed and then impacted and collided by the high-speed airflow to be smashed into a mist shape; an ultrasonic airflow atomization function, so that the airflow atomization effect can effectively enhanced and compressed air can be saved; an outlet liquid drop atomizing function, so that air-material mixed mist can airflow-atomize condensation mass discharged along the wall again; simple structure, large material through holes and blocking-resistance. Besides, the inside-mixing atomizing nozzle device can well atomize fluid materials with poor fluidity, high solid content and high viscosity or even containing particle or fiber impurities.

Description

technical field [0001] The invention relates to an atomizing device for fluid materials, which is an internal mixing atomizing nozzle device used in multiple application fields such as fire protection, environmental protection, drying, incineration and spraying. Background technique [0002] Atomization technology is widely used in fire protection, environmental protection, drying, incineration, powder metallurgy, metal forming and other fields. [0003] Chinese patent application CN102357336A discloses "an adjustable Venturi tube double-layer structure atomizing nozzle". The nozzle device forms "liquid-in-gas" in the cone-shaped spray chamber with the atomized slurry and the pressure air ejected from the Venturi tube, and is broken and crushed under the action of high speed and pressure difference, and is ejected from the nozzle to form an atomized . [0004] Chinese patent application CN103115359A discloses "a gas-assisted atomizing nozzle for atomizing high-viscosity fl...
