Description

Detailed Description of the Invention

The present invention facilitates maintenance in fluid spraying by avoiding clogging due to deterioration over time so that fine particles are not obtained, so that maintenance is facilitated, and linear discharge is achieved by changing the size and pressure of the fluid discharge port. The present invention relates to a spherical or elliptical spherical double structure pressurized fine spray nozzle characterized in that it can be easily switched from a fine spray to a fine spray.

  There are various types of spray nozzles depending on the application, and structures suitable for each purpose have been developed. However, many of the conventional products have a cone shape depending on the pressure and the size and shape of the hole of the fluid ejection port. It is made so that a fluid in the form of a fan or a flat mist can be obtained, but when trying to obtain a fine mist, the holes are extremely small and it is easy to see if iron, chlorine, calcium, etc. are not removed in the fluid pretreatment Improvements such as prevention of deterioration with time due to clogging or blockage have been desired.

In particular, there are no nozzles that can handle negative ion generators and spherical cyclone deodorizers, the spray quality is fine and the method of increasing the volume is almost impossible, and trying to make the spray quality finer makes the holes extremely small and finer Even if mist is obtained, the absolute amount of spray cannot be ensured, and the concentration of negative ions per cm ³ is increased by the method based on the collision effect of water and air, that is, the number of negative ions generated per cm ³ is increased. I couldn't make it.

  In a deodorizing method using a negative ion generator, a water scrubber, or a spray dryer, an excellent nozzle has been awaited for ensuring the quality and quantity of spray. In addition, due to the high frequency of use, clogging and failure must be prevented, and it is better to have a very simple structure. In practice, however, complicated methods are used, and some complicated methods are enthusiastic. Although it seems that the purpose will be achieved at the beginning, it is often clogged and often cannot be used.

Problems to be solved by the invention

望んでいる目詰まりしない微細噴霧等の流体中の水と空気の接触に重要な問題を解決する為になされたものであり、水は循環タンクに回収され、循環水ポンプにより繰り返し再利用される水の先端部のノズルに使用されても目詰まりせずに噴霧を行うことが出来、尚粘性のある焼酎粕や下水汚泥等の霧化を図り、発生噴霧量も充分確保出来る球形又は楕円球形二重構造加圧微細噴霧ノズルを提供する。The present invention provides the above-described negative ion generator and removal of particulates discharged from a diesel engine.

It was made to solve the important problem of contact between water and air in fluids such as fine spray that does not clog, and water is collected in a circulation tank and reused repeatedly by a circulation water pump. Spherical or elliptical spheres that can be sprayed without clogging even when used for nozzles at the tip of water, can still atomize viscous shochu and sewage sludge, etc., and can secure a sufficient amount of generated spray A dual structure pressurized fine spray nozzle is provided.

Means to solve the problem

  In order to solve the above problems, the spray nozzle of the present invention is provided with one or more inlets in a tangential direction in a spherical shape or an elliptical spherical shape for spraying a liquid at the tip, and an arbitrary part of the same spherical shape. A sphere of any size, which has a squirting hole of a size, is attached with a slightly larger hole diameter and a pressure air guide ring at the same position as the squirting port, and is provided with a pressurized air introduction part by an external compressor or the like It is characterized by an extremely simple structure in which an elliptical spherical pressure vessel is attached to a double structure.

  In addition, since the present invention has a simple structure, it is easy to manage hygiene, and when the inner surface is mirror-finished, it is difficult for general bacteria to adhere, and a constant pressure is applied to the inner surface of the sphere, causing a swirling flow. Since the inside cleaning of the nozzle is repeatedly performed by the fluid, it is characterized in that it can be widely used in food factories.

  Furthermore, the spherical or elliptical spherical double structure pressurized fine spray nozzle of the present invention can be sprayed while mixing not only one fluid but also a plurality of inlets while mixing two or more liquids. However, it is not limited to one place, but has a feature that can be considered as a method of using a nozzle that is not conventionally used as a fountain.

  With the above-mentioned present invention, the liquid nozzle may introduce the liquid into a cylinder, a conical shape or the like regardless of the spherical shape or the elliptical spherical shape, and has an outer shell spherical pressure vessel having a guide ring when the liquid is sent to the liquid ejection port. The pressure gas ejected from the pressure gas outlet is atomized by capillary action and collision effect.

  Next, an embodiment related to a spherical or elliptical spherical double structure pressurized fine spray nozzle of the present invention will be described with reference to FIGS. In FIG. 1, the spray nozzle of the present invention comprises a spherical or elliptical and cylindrical / conical (1) nozzle for spraying a liquid, and is provided with an inlet 2 in a tangential direction, a jet outlet 3, a pressure inlet 5, It consists of a gas outlet 4.

  The spout 3 of the spherical or elliptical spherical double structure pressurized fine spray nozzle does not need to be a small hole, and sufficiently fine particles can be obtained with the spout 3 that does not clog 1 mm or more. When the pressure is low, the fluid flow matches the diameter of the hole, but as the pressure increases, a sprayed state is formed. The inlet 2 may be thickened to increase the amount of inflow, or the liquid inner shell nozzle may be of any shape such as spherical, cylindrical, conical, etc., and the outer shell nozzle for pressurized gas may have a spherical or elliptical spherical shape of any size. By setting, a swirl flow can be obtained together with the diffusion of the fluid, and by increasing the surface area of the gas, drying with hot air or the like is performed quickly, and a nozzle that can satisfy the user's purpose with a simple structure is provided.

  The spout 3 of the spherical or elliptical spherical double structure pressurized fine spray nozzle may be a small hole. However, the smaller the nozzle 3, the more the nozzle becomes the same as the prior art nozzle and clogging occurs. The size should not be clogged. The spray pattern can be manufactured up to several thousand kinds of spray nozzle items by combining the spouts 3 and 4 and the introduction ports 2 and 5 and the spherical or elliptical sphere, and can satisfy the satisfaction of most users.

    The product of the present invention has a spherical or elliptical spherical double structure pressurized fine spray nozzle (1) at the tip and stops the operation without dripping while the fluid is filled. There is also an advantage of entering the work without waiting for the time to reach the tip.

  The material of the liquid nozzle of the present invention is not particularly selected, and plastics may be used, and it may be made of a metal or the like, and has a cylindrical / conical shape and a sphere or an elliptical sphere. Anything is acceptable.

The nozzle which is fed by a compressor other than this patent having an arbitrary hole diameter slightly larger than the mouth is provided with a pressure air jet port, and the liquid ejected from the inner liquid nozzle is capillaryized by the double structure outer pressure air nozzle. Provided is a spray nozzle for causing a gas-liquid collision effect together with a phenomenon, further miniaturizing a spray particle shape, and increasing a liquid surface area to facilitate drying of viscous waste liquid and sludge.
