The far-range high-flow tapered pneumatic nozzle is high in injection quantity, far in range and wide in injection range.
Description
Technical field
The utility model relates to a kind of nozzle, is mainly used in the environment such as water mist dust fall of tank switching setting of steelmaking process.
Background technology
More existing utilizations of taper pneumatic nozzle at present, but can not satisfy special application scenario.Water mist dust fall like the tank switching setting of steelmaking process; The water mist dust fall of blast furnace casting mouth of a river setting.At these settings, require in the course of work of hydraulic spray nozzle, its control system is occurring under any malfunction, and jet hole must not spray or flow out water column, otherwise security incident will occur, or serious accident; So hydraulic spray nozzle must be sprayed outside setting 3 ~ 5m; The water yield that the process need of water mist dust fall is enough.
So-called pneumatic nozzle is promptly: be the region of no pressure (negative pressure) that the periphery through gas jet produces, link to each other because region of no pressure and water get into the chamber, so water will be collided mixed aerosol by automatic suction and gas.
The taper pneumatic nozzle is typical in the spray gun for paint nozzle at present; Its major defect: because structure of nozzle; Gas, water mix outside end; Gas spreads very soon after penetrating, is that vacuum workspace is little that the effectiveness of the vacuum that the periphery of gas jet produces is low, so the discharge of spraying stream little (per hour a few liter); Because the mixed water smoke of collision does not have boot segment, so range short (about 1 meter).
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide that a kind of emitted dose is big, far firing range, the wide big flow pneumatic nozzle of long drive journey taper of spray regime.
The technical scheme of the utility model employing is for this reason: comprise some pneumatic nozzles; The version of each pneumatic nozzle is: comprise the pneumatic nozzle body that is provided with water inlet, water smoke outlet, the pneumatic energy nozzle that is provided with air inlet; The gas outlet of said pneumatic energy nozzle is arranged in the pneumatic nozzle intracoelomic cavity, and the position of said water inlet and gas outlet is corresponding; Each pneumatic nozzle tilts circumferentially all to be arranged in the mounting disc, and the mounting disc center connects a water inlet pipe, and water inlet pipe is communicated with through intake tunnel and each water inlet; The mounting disc bottom is provided with the air cavity that is communicated with each pneumatic nozzle air inlet.
Said pneumatic nozzle intracoelomic cavity comprises the conical section and the cylindricality water smoke boot segment that is provided with above that of gas-vapor mix, and said gas outlet is arranged in the conical section of pneumatic nozzle intracoelomic cavity.
The distance of mist outlet that said gas outlet is dried up is 2.5-3.5 a times of water smoke outlet aperture.
The distance of mist outlet that said gas outlet is dried up is 3 times of water smoke outlet aperture.
The nozzle arrangements of the utility model makes the portion's mixing within it of gas, water; Produce the district, be that vacuum workspace is big through suitable one section vacuum after gas penetrates; The effectiveness of the vacuum that the periphery of gas jet produces is high, so the discharge of spraying stream big (per hour 100 more than ten liters); Because the mixed water smoke of collision is provided with boot segment, so far firing range (about 5 meters).
The utility model is owing to adopt above-mentioned long drive journey taper pneumatic nozzle principle and with its Combination Design cleverly, makes the spray angle of the nozzle that its spray angle on the basis of the above is more traditional greatly enlarge.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of pneumatic nozzle.
Fig. 3 is the structural representation of conventional spout.
1 is that pneumatic nozzle body, 2 is air cavity for water inlet pipe, 10 for air inlet pipe, 9 for air inlet, 8 for pneumatic energy nozzle, 7 for water inlet, 6 for conical section, 5 for cylindricality water smoke boot segment, 4 for water smoke outlet, 3 in the picture in picture.
The specific embodiment
Each nozzle of the utility model comprises that the outside that is provided with the pneumatic energy nozzle 7 that is provided with air inlet 6, pneumatic energy nozzle 6 is provided with and it cooperates pneumatic nozzle body 1, and pneumatic nozzle body 1 sidewall is provided with water inlet 5, and the gas outlet of pneumatic energy nozzle 6 is arranged in the conical section 4; Its gas outlet apart from the distance of water smoke outlet 2 be the water smoke outlet aperture 2.5-3.5 doubly, preferentially elect 3 times as.
The course of work of each nozzle of the utility model is: gas is by air inlet 7 inputs of pneumatic energy nozzle 6; Gas penetrates at a high speed through the outlet of pneumatic energy nozzle 6; The periphery of gas jet produces vacuum effect, promptly forms region of no pressure (negative pressure), because the region of no pressure links to each other with intake antrum; Water will be by automatic suction and gas collision mixed aerosol, and mixed then air water body will export 2 forms with water smoke and spray at a high speed along cylindricality water smoke boot segment 3 from water smoke.
The utility model is dressed up following version with the nozzle sets of said structure form: its external structure includes air inlet pipe 8, air cavity 10, water inlet pipe 9, lock nut, sealing gasket; The compressed air of the utility model inputs in the air cavity 10 from air inlet pipe 8; Gas is distributed in the pneumatic energy nozzle that is provided with air inlet 76 with certain angle setting that its end face is uniformly distributed with Φ II circle and ejaculation through air cavity 10; When the outlet of pneumatic energy nozzle 6 is penetrated at a high speed; The periphery of gas jet produces vacuum effect, promptly forms region of no pressure (negative pressure), because the region of no pressure links to each other with water inlet 5; Water will be by automatic suction and gas collision mixed aerosol, and mixed then air water body will export straight length along water smoke and spray at a high speed with the form of water smoke.
The utility model is arranged to certain angle each other with a plurality of pneumatic nozzle bodies 1, makes the spray angle of the big flow pneumatic nozzle of long drive journey taper enough big.
For the discharge of pneumatic nozzle is even, for this reason: just intake tunnel is arranged in the middle entering gas nozzle body 1 of a plurality of pneumatic nozzle body 1 water inlets 5.
