Problems solved by technology

How to charge the droplets is a key issue. There are three main methods for charging droplets in the prior art: (1) corona charging method; (2) contact charging method; (3) inductive charging method, in which the inductive charging method The charging method is to install an induction electrode outside the nozzle outlet, so that the moment the liquid forms water mist at the nozzle outlet, according to the principle of electrostatic induction, the sprayed mist has a charge opposite to the polarity of the external electric field. Compared with the first two The method is safer, but in actual use, due to the attraction of the external electric field to the charged spray, some droplets with small kinetic energy will be adsorbed on the electrode and drip from the nozzle, causing waste and environmental pollution. Even if leakage occurs, the improved profiling electrode electrostatic nozzle can not solve this problem well

Abstract

The invention discloses an inductive electrostatic spray head. The inductive electrostatic spray head is characterized in that the inductive electrostatic spray head is provided with a closed charged chamber, the outlet end of an inner cavity of the charged chamber communicates with a spray opening of the spray head, the inlet end of the inner cavity of the charged chamber communicates with a water inlet pipe, an induction electrode is installed in the side wall of the charged chamber, and the inner cavity of the charged chamber is isolated from the induction electrode through an insulating material. The inductive electrostatic spray head can conduct charging on liquid drops in a closed environment, the problem that drops flow due to attractive force of an electrode outside an existing spray head can be effectively solved, environment protection and energy saving are achieved, and the spray head is suitable for being applied and popularized; according to a better improved scheme, through the Venturi effect, gas is introduced into liquid, thus, gas-liquid two-phase flow is formed, and compared with pure liquid spraying, the spraying charge capacity can be improved more substantially; and the inductive electrostatic spray head is novel in structure design, reasonable in plan, convenient to use and easy to produce and manufacture.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to electrostatic spraying technology. Background technique [0002] Electrostatic spraying technology is to use high-voltage static electricity to establish an electrostatic field between the nozzle and the spray target. After the pesticide fluid is atomized by the nozzle, it is charged by different charging methods to form a group of charged droplets, and then the electrostatic field force and Under the joint action of other external forces, the droplets make directional movement and are adsorbed on various parts of the target, achieving good performances such as high deposition efficiency, less droplet drift and loss, and improved ecological environment. How to charge the droplets is a key issue. There are three main methods for charging droplets in the prior art: (1) corona charging method; (2) contact charging method; (3) inductive charging method, in ...
