Abstract
The invention relates to a vacuum pump, in particular to a multi-stage vacuum pump which comprises a pipeline. The multi-stage vacuum pump is characterized in that vacuum pumps are uniformly connected onto the pipeline at intervals, and each vacuum pump is connected with an independent gas storage tank. The multi-stage vacuum pump has the advantages that the multi-stage vacuum pump is unique in structure, energy of compressed air can be used as power, and dust and fume on small areas can be sucked by the aid of the multi-stage vacuum pump.
Description
Technical field
The present invention relates to a kind of vacuum pump, especially relate to a kind of multistage vacuum pump.
Background technique
Foundry work scene, the operations such as welding, gouge, cast, knockout, cutting all can produce many flue dust, in factory building, assemble, and affect foundry goods transhipment safety and employee healthy.The current method solving for problems is: the first, and use flameproof textile and scrap steel etc. to make easy flue dust aggregation cover, but after flue dust is assembled completely in these easy flue dust aggregation covers, still can overflow from gap and bottom; The second, open the window of factory building, increase cross-ventilation, but when larger with flue dust in the winter time, can not all open again the window of factory building.Factory building volume of smoke operation has all been built dust chamber at present, but deduster use is all heavy-duty motor, the long-time waste electric energy of opening.
Up to the present, also there is no a kind of device that overcomes above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of structure uniqueness being provided, can using pressurized air can be power, absorbs the multistage vacuum pump of small size flue dust.
A kind of multistage vacuum pump, it comprises pipeline, it is characterized in that: on pipeline, interval is connected with vacuum pump uniformly, each vacuum pump is all connected with gas holder independently;
Each described vacuum pump is arranged on the shaft core position of described pipeline;
Described vacuum pump is ejector vacuum pump;
Described gas holder upper end is with pressure gauge and safety valve, and lower end is furnished with supporting wheel.
The present invention has following effect:
1) structure uniqueness: it comprises pipeline multistage vacuum pump provided by the invention, it is characterized in that: interval is connected with vacuum pump uniformly on pipeline, each vacuum pump is all connected with gas holder independently; The gas source of each vacuum pump is independently used and is connected with gas holder and controls separately.According to scene smoke evacuation ability to work need multiple combine just formed multistage.
2) can use pressurized air can be power, absorbs small size flue dust: working principle of the present invention is; Can utilize self-contained gas holder as the each own valve control that is connected with gas holder respectively of the mouth of pipe of power source, ABCD pump, according to on-the-spot flue gas discharge capacity successively turn on pump, reach the object of pressurization one by one, safe effect is played with pressure gauge and safety valve in gas holder upper end, and gas holder lower end is furnished with four wheels and can moves to Anywhere.Multistage vacuum pump is realized the effect of multiple single-stage vacuum pump series connection by plural serial stage, so the effect that multistage vacuum pump has the larger larger smoke evacuation of pumping speed pipeline vacuum degree than single-stage vacuum pump is better.
3) what the invention provides that the design adopts is ejector vacuum pump, and its cardinal principle is that the gas that goes out with high velocity jet of power jet drives and accelerate gas around.It is mobile forward that this motion causes pipeline to form vacuum drive pipe gas flow.Along with the speed that the needs of on-the-spot exhaust smoke level spray can be according to the size of opening one by one adjustable air inlet and exhaust of pump.
4) on the sandbox of the present invention after being poured, test, can effectively grow distance small size flue dust to be retracted to factory building window outer or for exhaling pernicious gases between welding region and narrow and small confined air operation, also can be used for searching and rescuing and speedily carry out rescue work, process accident protection workman and people life property safety.
5) invention in use, has only utilized pressurized air as power, has effectively substituted the electrical machine energy-saving environmental protection that consumes electric energy.
6) this instrument can reach environmental protection, source of the gas can utilize compressed air pump to gas holder aerating, nonflammable explosion-proof, non-maintaining, the low less investment of cost, simple to operate, flexibly mobile of safety, can according to need of work can make size all can, Portable, underground mining wear-type smoke absorbing hood, precision equipment confined space are kept a public place clean etc.
7) this invents industrial and civilian have very large economic value and wide market appreciation space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of the present invention while using.
Embodiment
A kind of multistage vacuum pump, it comprises pipeline 1, as shown in Figure 1: on pipeline 1, interval is connected with vacuum pump 2 uniformly, each vacuum pump 2 is all connected with gas holder 3 independently;
Each described vacuum pump 2 is arranged on the shaft core position of described pipeline 1;
Described vacuum pump 2 is ejector vacuum pumps;
Described gas holder 3 upper ends are with pressure gauge and safety valve, and lower end is furnished with supporting wheel.
As shown in Figure 2: this invention is moved to moulding cast scene or cleaning area of weldment, specifically use step as follows:
Step 1: utilize flexible pipe that described pipeline 1 and flue dust collecting cover 5 are linked together;
Step 2: utilize flexible pipe that compressed air reservoir 3 is connected with vacuum pump 2;
Step 3: the gas valve of opening each vacuum pump 2 according to on-the-spot fume amount;
Step 4: draw a flexible pipe at pipeline 1 end, flexible pipe is guided to filtrating smoke dust mechanism, play noise reduction and environmental-protection function in the middle of dusting apparatus, smoke filter etc., if small-sized can not considering.
The flue dust that continues after cast to produce will, according to the direction of arrow in figure, flow in filtrating smoke dust mechanism along pipeline.
Sequence number 4 is pressurized air and gas bag interface.
