Abstract
The invention relates to a vacuum generator, in particular to a parallel-connection vacuum generator. The parallel-connection vacuum generator comprises at least two sets of vacuum generator bodies. The vacuum generator bodies are arranged inside a vacuum generator outer shell in a parallel-connection mode. The vacuum generator outer shell comprises a compressed air inlet, a compressed air outlet and a vacuum port. Each vacuum generator body comprises a spray nozzle and an expansion pipe. Vacuum ports are formed in the expansion pipes, compressed air enters the vacuum generator bodies through the compressed air inlet of the vacuum generator outer shell and then leaves a vacuum compressor from the compressed air outlets respectively through the expansion pipes of the vacuum generator bodies and the spray nozzles of the vacuum generator bodies. According to the vacuum generator, the at least two sets of vacuum generator bodies are adopted, when workpieces which are loose in material and high in self-weight are carried, the vacuum generator body which is high in gas displacement can be used for reaching the set vacuum degree as soon as possible, the vacuum generator body which is low in flow can be used for maintaining vacuum, and therefore the pace requirement of an automatic line can be met, the working reliability is guaranteed, and meanwhile, the requirement for energy conversation is met. Thus, satisfying effects can be obtained.
Description
Technical field
The present invention relates to a kind of vacuum generator, particularly a kind of parallel vacuum producer.
Background technology
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 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, loose in conveyance material but while conducting oneself with dignity workpiece heavier, because material is loose, vacuum breaking speed, vacuum generator will frequently be restarted, and so not only energy consumption is high, and poor safety performance even affects service life.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind ofly for carrying that material is loose but the heavier workpiece of conducting oneself with dignity had both met beat requirement, guaranteed again the parallel vacuum producer of functional reliability.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of parallel vacuum producer, it is characterized in that, comprise at least two group vacuum generators, described vacuum generator parallel connection is located in a vacuum generator shell, described vacuum generator shell comprises compressed air inlet, compressed air outlet and vacuum port, described vacuum generator comprises nozzle and convergent divergent channel, described convergent divergent channel is provided with vacuum port, pressurized air enters parallel vacuum producer through the compressed air inlet place of described vacuum generator shell, again respectively through convergent divergent channel and the nozzle of described at least two group vacuum generators, finally from the compressed air outlet of vacuum generator shell, discharge.
Described at least two nozzles of group vacuum generator and the size of convergent divergent channel are different.
Described vacuum generator inner nozzle and convergent divergent channel junction are provided with check valve.
Described vacuum generator shell compressed air inlet place is provided with distribution of air flow valve.
Usefulness of the present invention is: the present invention adopts the combination of at least two group vacuum generators, while loosening, conducting oneself with dignity in conveyance material workpiece heavier, because the vacuum generator by large free air capacity reaches setting degree of vacuum as early as possible, with the vacuum generator of low discharge, keep vacuum, thereby both met the beat requirement of automation line, guaranteed again functional reliability, reached energy-conservation requirement simultaneously, so can obtain satisfied effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of Reference numeral in figure: 1 parallel vacuum producer; 2 vacuum generators; 21 nozzles; 22 convergent divergent channels; 23 check valves; 3 vacuum generators; 31 nozzles; 32 convergent divergent channels; 33 check valves; 4 vacuum generator shells; 41 compressed air inlet; 42 compressed air outlets; 43 vacuum ports; 44 distribution of air flow valves.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of parallel vacuum producer 1, comprises at least two group vacuum generators, preferably 2 groups of vacuum generators 2 and vacuum generator 3 in the present embodiment.Vacuum generator 2 and vacuum generator 3 parallel connections are located in a vacuum generator shell 4, and vacuum generator shell 4 comprises compressed air inlet 41, compressed air outlet 42 and vacuum port 43.Vacuum generator comprises nozzle and convergent divergent channel, and convergent divergent channel is provided with vacuum port.The nozzle of vacuum generator and the size of convergent divergent channel are different, and in the present embodiment, the size of nozzle 21 is less than nozzle 31, and the size of convergent divergent channel 22 is less than convergent divergent channel 32.The difference of nozzle and convergent divergent channel size causes that vacuum generator 2 free air capacities are less but degree of vacuum is higher, and vacuum generator 3 free air capacities are large but degree of vacuum is lower.Vacuum generator 2 and vacuum generator 3 inner nozzles and convergent divergent channel junction are provided with check valve 23 and check valve 33.Check valve stops air to leak to vacuum loop, makes vacuum continue to keep.Vacuum generator shell 4 compressed air inlet places are provided with distribution of air flow valve 44.
During work, distribution of air flow valve 44 is first to vacuum generator 3 air feed, because the free air capacity of vacuum generator 3 is large, degree of vacuum is lower, so negative pressure forms very soon.When degree of vacuum reaches setting value, distribution of air flow valve 44, to vacuum generator 2 air feed, because vacuum generator 2 discharge capacities are less, degree of vacuum is higher, makes the vacuum generator energy long period keep vacuum state.
Or during work, distribution of air flow valve 44, simultaneously to vacuum generator 2 and vacuum generator 3 air feed, when degree of vacuum reaches setting value, stops to vacuum generator 3 air feed, only gives vacuum generator 2 air feed, in order to continue to keep vacuum.
More than show and described groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
