Abstract
The invention relates to a vacuum generator, in particular to a tandem type vacuum generator. The tandem type vacuum generator comprises at least two sets of vacuum generator bodies and a vacuum generator outer shell. Each vacuum generator body comprises a nozzle and an expansion tube, and a vacuum opening is formed in each expansion tube. According to the at least two sets of vacuum generator bodies, the nozzle of the previous vacuum generator body is connected with the expansion tube of the next vacuum generator body to form serial connection, and the at least two sets of vacuum generator bodies are together arranged in the vacuum generator outer shell. The vacuum generator outer shell comprises a compressed air inlet, a compressed air outlet and a vacuum opening, and compressed air enters the tandem type vacuum generator from the compressed air inlet of the vacuum generator outer shell, sequentially passes through the at least two sets of vacuum generator bodies and is discharged from the compressed air outlet of the vacuum generator outer shell. Multiple vacuum generator bodies are connected in series, the energy of the compressed air discharged from the previous vacuum generator body is recycled, and therefore the time for achieving vacuum is shortened, and the sorption rapidity of the vacuum generator is improved.
Description
Technical field
The present invention relates to a kind of vacuum generator, particularly a kind of tandem vacuum generator.
Background technique
Traditional vacuum generating device is to utilize vacuum pump, and electric energy conversion is mechanical energy, and driven rotary blade is told rotation, makes the discharge of air and suck to accelerate, and forms vacuum.But this vacuum system volume is large, quality heavy, noise is large, energy consumption is high, can not adapt to the requirement that some accurate manufacturings are more and more higher gradually, therefore, a kind of utilize the vacuum vacuum generator of pressurized air because its volume is little, quality is light, degree of vacuum is high, respond the feature such as fast and replaced traditional vacuum generating device.This kind of vacuum generator often applies to the industries such as electronics, chemical industry, building, food, plays vacuum adsorption carrying and vacuum adsorption fixing.But in prior art, when the very fast workpiece of conducting oneself with dignity heavier of carrying beat, generally adopt the vacuum generator of large discharge capacity, but this vacuum generator comsumption of compressed air is large.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of for carrying the tandem vacuum generator of the heavier workpiece of the very fast deadweight of beat.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of tandem vacuum generator, comprise at least two group vacuum generators and vacuum generator shell, described vacuum generator comprises nozzle and expanding duct, on described expanding duct, there is vacuum port, described at least two group vacuum generators are connected to form and are connected in series by the nozzle of previous vacuum generator and the expanding duct of a rear vacuum generator, and be jointly located in described vacuum generator shell, described vacuum generator shell comprises compressed air inlet, compressed air outlet and vacuum port, pressurized air enters tandem vacuum generator from the compressed air inlet place of vacuum generator shell, at least two group vacuum generators described in passing through successively, through the compressed air outlet of vacuum generator shell, discharge again.
Described at least two nozzles of group vacuum generator and the size of expanding duct are different.
The size of described at least two group vacuum generators increases to compressed air outlet successively from compressed air inlet.
In described at least two group vacuum generators, the expanding duct of a rear vacuum generator is the nozzle of previous vacuum generator.
Described nozzle and expanding duct joint are provided with one-way valve.
Usefulness of the present invention is: the present invention adopts a plurality of vacuum generator series connection, owing to having recycled the compressed air energy that upper level vacuum generator is discharged, under same energy consumption, increase gross exhaust gas, shortened vacuum time of advent, improved the sorption rapidity of vacuum generator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is another preferred embodiment schematic diagram of the present invention.
The implication of reference character in figure: 1 tandem vacuum generator; 2 vacuum generators; 21 expanding ducts; 22 nozzles; 23 one-way valves; 24 vacuum ports; 3 vacuum generators; 31 expanding ducts; 32 nozzles; 33 one-way valves; 24 vacuum ports; 4 vacuum generator shells; 41 compressed air inlet; 42 compressed air outlets; 43 vacuum ports.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of tandem vacuum generator 1 as shown in Figure 1, comprise at least two group vacuum generators, in the present embodiment, be two groups, vacuum generator 2 and vacuum generator 3, vacuum generator comprises nozzle and expanding duct, on expanding duct, have vacuum port, the nozzle 22 of vacuum generator 2 is connected to form and is connected in series with the expanding duct 31 of vacuum generator 3, is jointly located in vacuum generator shell 4.In another preferred embodiment, the nozzle 22 of vacuum generator 2 is the expanding duct 31 of vacuum generator 3.The nozzle of vacuum generator 2 and vacuum generator 3 and the size of expanding duct are different, and size increases to compressed air outlet 42 successively from compressed air inlet 41.Nozzle and expanding duct joint are equipped with one-way valve, and the application of one-way valve can effectively stop air to leak to vacuum loop, make vacuum continue to keep.
During work, pressurized air enters tandem vacuum generator 1 through compressed air inlet 41 places of vacuum generator shell 4, first enters vacuum generator 2, produces after vacuum, the air-flow of discharging from nozzle 22, again as the source of the gas of vacuum generator 3, continues the gas of suction airtight cavity.Because vacuum generator 2 is different with vacuum generator 3 sizes, air pressure is different, the degree of vacuum of vacuum generator 3 is starkly lower than the degree of vacuum of vacuum generator 2, after airtight cavity degree of vacuum is higher than 3 degree of vacuum that can reach of vacuum generator, the loop that cuts off vacuum port 33 with the airtight cavity of vacuum generator 3, is vacuumized separately by vacuum generator 2.
Tandem vacuum generator great advantage is in the situation that comsumption of compressed air is identical, and vacuum generation speed has improved a lot.If adopt to increase the method for serial number, as three, tetrad formula vacuum generator can further improve air displacement and shorten vacuum time of advent.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
