Description

Novel energy-saving steam ejector

Technical Field

The utility model relates to a steam ejector technical field specifically is an energy-conserving novel steam ejector.

Background

Steam ejectors are an application of jet technology in the field of heat transfer. The steam ejector has the advantages of simple structure, low investment and reliable operation, can reasonably match the pressure grade of steam, recover low-grade steam and improve the utilization efficiency of the steam, and is an important way for saving energy. The method is widely applied to the industries of food, pharmacy, chemical industry, metallurgy and the like. Steam ejector's theory of operation produces high-speed air current when high-pressure steam passes through the nozzle, produces the low-pressure region at nozzle exit, but when high-pressure steam passes through the nozzle, can strike and corrode the nozzle, and then lead to the nozzle to damage easily, and present steam ejector's nozzle and spray tube all are integrated into one piece, and the spray tube all is that the beading is in the suction chamber, and inconvenient dismantlement is changed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an energy-conserving novel steam jet ejector to solve the problem of the inconvenient dismantlement of nozzle and spray tube of the steam jet ejector who provides among the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides an energy-conserving novel steam ejector, includes air inlet flange dish, suction chamber, mixing chamber, diffusion chamber and the ring flange of giving vent to anger, air inlet flange dish right-hand member rigid coupling has the spray tube, spray tube right-hand member female connection has the nozzle, spray tube and nozzle insert in the suction chamber, threaded ring one has been cup jointed in the spray tube left end periphery, it has thread groove one to open in the suction chamber left side, threaded ring one with threaded connection mutually between the thread groove one.

Furthermore, a second thread groove is formed in the right end of the spray pipe, a second thread ring is fixedly connected to the left end of the spray nozzle, and the second thread ring is in threaded connection with the second thread groove.

Furthermore, the left side and the right side of the nozzle are both horn-shaped structures.

Furthermore, the caliber of the air inlet at the left side of the nozzle is larger than that of the air outlet at the right side.

Compared with the prior art, the utility model discloses the beneficial effect who reaches is:

the utility model discloses an earlier screw out the spray tube, then unscrew the nozzle and change for the dismantlement of nozzle and spray tube is more convenient, and the steam ejector of being convenient for carries out routine maintenance, and then has improved steam ejector's maintenance efficiency and life.

FIG. 2 is a sectional view of the connection structure between the intake flange and the suction chamber;

fig. 3 is an enlarged schematic view of a in fig. 2.

In the figure: 1. an air inlet flange plate; 2. a suction chamber; 3. a mixing chamber; 4. a diffusion chamber; 5. an air outlet flange plate; 6. a nozzle; 7. a nozzle; 8. a first threaded ring; 9. a first thread groove; 10. a second thread groove; 11. and a second threaded ring.

Detailed Description

For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.

According to the utility model discloses an embodiment provides an energy-conserving novel steam jet ejector.

The first embodiment is as follows:

as shown in fig. 1-3, a novel energy-saving steam ejector comprises an air inlet flange plate 1, a suction chamber 2, a mixing chamber 3, a diffusion chamber 4 and an air outlet flange plate 5, wherein a spray pipe 6 is fixedly connected to the right end of the air inlet flange plate 1, a nozzle 7 is connected to the right end of the spray pipe 6 through internal threads, the spray pipe 6 and the nozzle 7 are inserted into the suction chamber 2, a first threaded ring 8 is sleeved on the periphery of the left end of the spray pipe 6, a first threaded groove 9 is formed in the left side of the suction chamber 2, and the first threaded ring 8 is in threaded connection with the first threaded groove 9;

example two:

a second thread groove 10 is formed in the right end of the spray pipe 6, a second thread ring 11 is fixedly connected to the left end of the spray nozzle 7, and the second thread ring 11 is in threaded connection with the second thread groove 10;

the left side and the right side of the nozzle 7 are both in horn-shaped structures;

the caliber of the left air inlet of the nozzle 7 is larger than that of the right air outlet;

the utility model discloses a theory of operation:

when the steam ejector needs daily maintenance, the spray pipe 6 is firstly screwed out of the suction chamber 2, then whether the nozzle 7 needs to be replaced is observed, if the nozzle 7 needs to be replaced, the threaded ring II 11 at the left end of the nozzle 7 is screwed out of the threaded groove II 10 at the right end of the spray pipe 6, then a new nozzle 7 is replaced, after replacement is finished, the spray pipe 6 and the nozzle 7 are inserted into the suction chamber 2, and the threaded ring I8 on the spray pipe 6 is screwed into the threaded groove I9 in the suction chamber 2, so that installation is finished;

consequently this practicality is through twisting out earlier spray tube 6, then unscrew nozzle 7 again and change for nozzle 7 and spray tube 6's dismantlement is more convenient, and the steam jet ware of being convenient for carries out routine maintenance, and then has improved steam jet ware's maintenance efficiency and life.
