Abstract
The utility model belongs to the field of mechanical equipment and particularly relates to a vacuumizing device which comprises a vacuum pump, a round lengthened nut and an air exhausting pipeline. The vacuumizing device is characterized in that the vacuum pump is connected with one end of the round lengthened nut through the air exhaust pipeline and provided with a vacuum negative pressure meter, and the other end of the round lengthened nut is welded to the outer surface of a storage tank. The vacuumizing device is simple in structure, convenient to use and practical, vacuumizing can be directly carried out on the surface of the storage tank, the overall effect of the interior of the storage tank is maintained, the number of the air exhaust pipeline and the round lengthened nut is increased, vacuumizing is uniform, and the effect is good.
Description
Technical field
The invention belongs to mechanical equipment configuration field, be specifically related to a kind of vacuum pumping device.
Background technique
In recent years, the demand of anticorrosion equipment is increasing, producing in anti-corrosion storage tank enterprise, mainly with anti-rot plastic plate, being attached to reservoir walls realizes corrosion-resistant function, after anti-rot plastic plate has pasted, between anti-rot plastic plate and reservoir walls, inserted pipeline and vacuumized in the past, but after vacuumizing end, pipeline is difficult to release again, can affect the whole structure of tank inside; More and more higher owing to requiring now, the gap between anti-rot plastic plate and reservoir walls is more and more less, cannot insert pipeline again, therefore, need to seek a kind of simple vacuum pumping method efficiently.
Summary of the invention
For addressing the above problem, the invention discloses a kind of vacuum pumping device, directly in reservoir surface, just can vacuumize, keep the attractive in appearance, complete of tank inside.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of vacuum pumping device, comprise vacuum pump, lengthen round nut, pump-line, it is characterized in that: described vacuum pump is connected by pump-line with lengthening round nut one end, and vacuum pump is provided with negative pressure of vacuum table, and the described lengthening round nut the other end is welded on storage tank outer surface.
As a modification of the present invention, described pump-line is identical with lengthening round nut number, is 1-10.
As a modification of the present invention, between described pump-line and lengthening round nut, be provided with stop valve.
As a modification of the present invention, described lengthening round nut specification is M12-M18.
The invention has the beneficial effects as follows:
Vacuum pumping device of the present invention is simple in structure, convenient and practical, directly in reservoir surface, just can vacuumize, and keeps the whole structure of tank inside, increases pump-line and lengthens round nut number, vacuumize more even, better effects if.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numerals list:
1, vacuum pump, 2, negative pressure of vacuum table, 3, pump-line, 4, stop valve, 5, lengthen round nut, 6, storage tank.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
As shown in the figure, a kind of vacuum pumping device of the present invention, comprise vacuum pump 1, lengthen round nut 5, pump-line 3, described vacuum pump 1 is connected by pump-line 3 with lengthening round nut 5 one end, vacuum pump 1 is provided with negative pressure of vacuum table 2, and described lengthening round nut 5 the other ends are welded on storage tank 6 outer surfaces.
Before work, in reservoir surface, bore 5-8mm hole, lengthening round nut 5 one end are welded on storage tank, the hole of brill, in lengthening round nut 5, connects pump-line 3, just can vacuumize, and notes negative pressure of vacuum table 2 scale, can not surpass-0.1Mpa.
By described pump-line 3 with lengthen round nut 5 numbers and increase to 1-10 simultaneously, vacuumize more even, better effects if.
For safety, between described pump-line 3 and lengthening round nut 5, be provided with stop valve 4.
For cost-saving, described lengthening round nut 5 specifications are M12-M18.
Technological means disclosed in this invention is not limited only to the disclosed technological means of above-mentioned mode of execution, also comprises the technological scheme being comprised of above technical characteristics combination in any.
