Abstract
The utility model relates to a steam jet vacuum pump nozzle structure. The steam jet vacuum pump nozzle structure comprises an operating nozzle, a mixing chamber and a diffusion chamber. The operating nozzle extending into the mixing chamber is installed at the front end of the mixing chamber, the back end of the mixing chamber is in series connection with the diffusion chamber, and a suction inlet is formed in the side wall of the mixing chamber. The steam jet vacuum pump nozzle structure is characterized in that the operating nozzle is composed by a plurality of small operating nozzles which are evenly distributed. The steam jet vacuum pump nozzle structure has the advantages that steam is evenly distributed, the steam is even mixed with pumped gas, steam power loss is small, and a vacuum-pumping effect is improved.
Description
Technical field
The utility model relates to a kind of steam jet vaccum nozzle arrangements, particularly a kind of steam jet vaccum nozzle arrangements of bleeding effective.
Background technique
The steam jet vaccum nozzle arrangements is because rate of air sucked in required is large, operating range is wide, simple in structure, the parts that do not have relative movement, be a kind of broad-spectrum vacuum equipment, be mainly used in the aspects such as degasification, decolouring, drying, deodorization, distillation, refrigeration and conveying.Particularly it is to sucking the gas non-selectivity, in food production, petrochemical industry, grease processing, production of polyester, contain the occasions such as the material of organic solvent is concentrated, compares with oil-sealed rotary pump and demonstrates remarkable advantage.
At present traditional steam jet vaccum nozzle arrangements adopts the single nozzle structure, and distribution of steam is inhomogeneous, and is poor with the mixed effect of pumped gas, affects vacuumizing effect, the explosion chamber single stage compression, and the fluctuation of mixed gas velocity variations is larger, and pumping efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of steam jet vaccum nozzle arrangements of bleeding effective.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of steam jet vaccum nozzle arrangements, comprise main jet, mixing chamber and explosion chamber, the mixing chamber front end is installed the main jet that stretches in the mixing chamber, mixing chamber rear end series connection explosion chamber, the mixing chamber sidewall is opened suction port, and explosion chamber is divided into compressing section, trunnion section and diffuser from front to back successively; Its innovative point is: described main jet is by the even distribution and constitution of several little main jets, and little main jet arranges mixing section, compressing section and diffuser from front to back.
The utility model has the advantage of: single nozzle parameter little main jet so that distribution of steam is even, mixes with pumped gas more even, the raising vacuumizing effect.
Description of drawings
Fig. 1 is the structural representation of the utility model steam jet vaccum nozzle arrangements.
Fig. 2 is the medium and small main jet structural representation of the utility model.
Embodiment
As shown in Figure 1, mixing chamber 2 front ends are installed the main jet that stretches into mixing chamber 2, and the rear end arranges explosion chamber 3, and mixing chamber 2 sidewalls are opened suction port a.
Main jet is by several little main jet 1 even distribution and constitutions, end socket is installed in the mixing chamber 2 front ends outside, the end socket inner chamber is communicated with the inlet end of little main jet 1, the end socket center goes into operation and makes steam inlet d, as shown in Figure 2, little main jet 1 arranges mixing section 11, compressing section 12 and diffuser 13 from front to back.
