Abstract

The utility model discloses an ejector which is composed of a compressed air interface, an ejection entering pipe, a pressure bolt, a spherical sleeve, a nozzle, an ejection sleeve pipe, a bolt, a horn tube, an exhaust sleeve barrel, a silencer and a silencing sleeve barrel, wherein one end of the ejection entering pipe is hermetically connected with the compressed air interface, and the other end is hermetically connected with the nozzle and the spherical sleeve; the pressure bolt is sheathed on the ejection entering pipe and is connected with the spherical sleeve; one end of the ejection sleeve pipe is hermetically connected with the spherical sleeve, and one end is hermetically connected with the horn tube; the exhaust sleeve barrel is connected with the silencing sleeve barrel via the bolt. The utility model not only has the advantages of simple structure and convenient operation, but also has the advantages that more stable vacuum degree can be continuously generated and the size of the vacuum degree can be adjusted within a definite range. The utility model is particularly suitable for a vacuum ladle to suck aluminium in an electrolysis workshop in an aluminium factory, and is also suitable for a system and an apparatus which require less to the size of the vacuum degree.

Description

Injector
Technical field:
The utility model relate to a kind of can vacuum creating equipment, particularly a kind of be used for aluminium manufacturer's potroom carry out vacuum ladle can vacuum injector when inhaling aluminium, belong to vacuum device technique field.
Background technology:
At present, in the prior art, aluminium manufacturer's potroom often adopts vacuum ladle suction aluminum technology to inhale aluminium, existing this vacuum ladle is inhaled aluminum technology not only will dispose compressed air when producing vacuum, but also needs the configuration vacuum system, make like this potroom the equipment complexity, use inconvenient, and the vacuum instability of its generation, vacuum big or small unadjustable, therefore, existing vacuum device its effect in use still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, easy to use and can continue to produce more stable vacuum, the injector of certain adjustable range is arranged, to overcome above-mentioned the deficiencies in the prior art.
The utility model is to constitute like this: it is gone into pipe (2), hold-down bolt (3), spherical cover (4), nozzle (5), injection sleeve pipe (6), bolt (7), oviduct (11), exhaust sleeve (12), muffler (13) and noise reduction sleeve (14) by compressed air interface (1), injection and forms, the end that injection is gone into pipe (2) links to each other with compressed air interface (1) sealing, the other end is tightly connected with nozzle (5) and links to each other with sphere cover (4) sealing, and hold-down bolt (3) is enclosed within injection and goes on the pipe (2) and with sphere cover (4) to be connected; One end of injection sleeve pipe (6) links to each other with spherical cover (4) sealing, and an end and oviduct (11) are tightly connected; Exhaust sleeve (12) links together by bolt (7) with noise reduction sleeve (14).
Owing to adopted technique scheme, injector of the present utility model adopts ejector principle to form vacuum, when its work, compressed air enter into by the compressed air interface that injection is gone into pipe and by nozzle ejection to oviduct, compressed-air actuated pressure is big more, then the air-flow jet velocity of nozzle is fast more, and pressure is big, large-minded, it is just fast more that then spherical cover forms vacuum, and its vacuum is just big more, when compressed air enters into oviduct, air flow slows, and carry out noise reduction by muffler and noise reduction sleeve, then from the blast pipe of exhaust sleeve, discharge.The general time that forms vacuum only needs about 3 minutes.By the internal diameter of adjustment injection sleeve pipe and the big I of internal diameter of nozzle the size of the value of vacuum is adjusted.Therefore the utility model compared with prior art, its not only have simple in structure, easy to use, can continue the advantage of the more stable vacuum of generation, and have the advantage that can regulate the vacuum size within the specific limits.The utility model is particularly suitable for the vacuum ladle of aluminium manufacturer's potroom and inhales the aluminium use, also applicable to system and the equipment not high to the vacuum size requirements.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1.
The specific embodiment:
Embodiment of the present utility model:
As shown in Figure 1, one end and the compressed air interface (1) of injection being gone into pipe (2) are tightly connected, the other end is tightly connected with nozzle (5) and links to each other with sphere cover (4) sealing, hold-down bolt (3) is enclosed within injection goes on the pipe (2) and with sphere cover (4) to be threaded; One end of injection sleeve pipe (6) is linked to each other with spherical cover (4) sealing, and the other end and oviduct (11) are tightly connected; Exhaust sleeve (12) is connected by bolt (7) with noise reduction sleeve (14) gets final product.Must guarantee when mounted respectively the to be tightly connected sealing at place, wherein compressed air interface (1) and injection are gone into pipe (2), injection and are gone into pipe (2) and go into spherical cover (4), injection that pipe (2) overlaps (4) with nozzle (5), injection sleeve pipe (6) with sphere, injection sleeve pipe (6) all is connected by thread seal with oviduct (11).In use spherical cover of the present utility model (4) is linked to each other with the vacuum interface of equipment.
Distance between nozzle (5) and the injection sleeve pipe (6) can be adjusted in use as required, and the distance of its adjustment is 0 ~ 20mm, should make mark and use hold-down bolt (3) locking after adjustment, so that draw required vacuum.
In use, after the internal diameter of injection sleeve pipe (6) is determined, can change nozzle (5) as required, the internal diameter of nozzle can be made φ 11, φ 10,9 three kinds of specifications of φ, needs the distance between corresponding adjustment nozzle (5) and the injection sleeve pipe (6) simultaneously.During use be: operating pressure: 0.6Mpa tolerance :~5m to compressed-air actuated requirement 3/ min, then the accessible vacuum of the utility model is about 42000Pa (or 450mmHg).
