Further provide a kind of concrete structure of vacuum-pumping pipeline, described vacuum-pumping pipeline has cold-trap and vacuum pumping pump, and the interlayer vacuum-pumping mouth of described gas cylinder is connected with the import of cold-trap, and the outlet of cold-trap is connected with vacuum pumping pump.
Stopping is vacuumized further in order to effectively prevent unexpected power-off or special circumstances from causing; can cutting-off valve immediately; gas cylinder is protected; vacuum-pumping pipeline also has import vacuum flapper valve, outlet vacuum flapper valve and Emergeny Cutoff Valves; import vacuum flapper valve and Emergeny Cutoff Valves are connected on the connecting pipeline between the import of cold-trap and the interlayer vacuum-pumping mouth of gas cylinder, and described outlet vacuum flapper valve is connected on the connecting pipeline between the outlet of cold-trap and vacuum pumping pump.
Further in order to remove the impurity in vacuum-pumping pipeline better, protection vacuum pump is not contaminated, and vacuum extractor of gas cylinders also comprises filter, and filter is connected on the connecting pipeline between the outlet of cold-trap and vacuum pumping pump.
Further in order to vacuumize in stove by being conveniently delivered to by gas cylinder, vacuum extractor of gas cylinders also comprises gas cylinder holding support and conveying track, and conveying track is delivered to and vacuumizes in the inner chamber of oven, and gas cylinder holding support and conveying track match.
After have employed technique scheme, by vacuumizing the heat temperature raising in oven, external heat is carried out to gas cylinder, simultaneously, the blower at oven top is utilized to vacuumize hot air in oven, and pass into gas cylinder, thus also heat in it, thus simultaneously to external heat in gas cylinder, gas cylinder farthest can be helped to discharge impurity, obtain good degree of vacuum, the utility model adopts the method for recovery waste heat, to gas cylinder internal heating, not only save the energy, also can control the temperature of interior external heat simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of vacuum extractor of gas cylinders of the present utility model.
Embodiment
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of vacuum extractor of gas cylinders, it comprises:
Vacuumizing oven 9, vacuumizing in oven 9 inner chamber be provided with for placing gas cylinder 12;
Blower 11, import and the intracavity inter-connection vacuumizing oven 9 of described blower 11, the outlet of blower 11 is connected with the gas cylinder 12 be placed in inner chamber;
Vacuum-pumping pipeline, vacuum-pumping pipeline is connected with the interlayer vacuum-pumping mouth of the gas cylinder 12 be positioned in inner chamber.
As shown in Figure 1, vacuum-pumping pipeline has cold-trap 4 and vacuum pumping pump 1, and the interlayer vacuum-pumping mouth of gas cylinder 12 is connected with the import of cold-trap 4, and the outlet of cold-trap 4 is connected with vacuum pumping pump 1; Cold-trap 4 can be nitrogen cold-trap.
As shown in Figure 1, vacuum-pumping pipeline also has import vacuum flapper valve 5, outlet vacuum flapper valve 2 and Emergeny Cutoff Valves 6, import vacuum flapper valve 5 and Emergeny Cutoff Valves 6 are connected on the connecting pipeline between the import of cold-trap 4 and the interlayer vacuum-pumping mouth of gas cylinder 12, and outlet vacuum flapper valve 2 is connected on the connecting pipeline between the outlet of cold-trap 4 and vacuum pumping pump 1.
As shown in Figure 1, vacuum extractor of gas cylinders also comprises filter 3, and filter 3 is connected on the connecting pipeline between the outlet of cold-trap 4 and vacuum pumping pump 1.
As shown in Figure 1, vacuum extractor of gas cylinders also comprises gas cylinder holding support 8 and conveying track 10, and conveying track 10 is delivered in the inner chamber vacuumizing oven 9, and gas cylinder holding support 8 and conveying track 10 match.
Working principle of the present utility model is as follows:
Gas cylinder 12 to be taken out overlays on gas cylinder holding support 8 before vacuum extraction, pushed by the conveying track 10 vacuumized outside oven 9 and vacuumize in oven 9, gas cylinder 12 is in vacuum, vacuumize oven 9 to start to heat up, treat gas cylinder 12 external heat taken out, the gas extraction vacuumized in oven 9 out constantly passes in gas cylinder 12 to be taken out by the blower 11 vacuumizing oven 9 outside, formed and the inside of gas cylinder 12 is heated, gas cylinder 12 to be taken out is placed on gas cylinder holding support 8, make once to vacuumize multiple gas cylinder 12, both the energy had been saved, can also Controlling Technology flow process effectively, gas in multiple gas cylinder 12 interlayer converges into a vacuum-pumping pipeline, water in gas and greasy dirt impurity are taken away by vacuum pump 1, when the impurity in gas is by cold-trap 4, the temperature of cold-trap 4 is very low, can water and impurity be condensed on the outer wall of cold-trap 4, thus protection vacuum pump 1 is not contaminated.Before cold-trap 4 and vacuum pumping pump 1, be provided with outlet vacuum flapper valve 2, import vacuum flapper valve 5 and Emergeny Cutoff Valves 6, effectively prevent unexpected power-off or special circumstances from causing and vacuumize stopping, can cutting-off valve immediately, gas cylinder is protected.
