Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provide a kind of mix full and uniform, keep flow output stable be used for the magnesium alloy efficient gas mixing device.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: be used for the magnesium alloy efficient gas mixing device, comprise blending tank, wherein: airtight first inlet suction port, second inlet suction port and the pressure switch of being through with in blending tank tank skin upside, the airtight air outlet adapter that is through with in blending tank tank skin lower side, the airtight drainage valve that is through with in blending tank tank skin lower side; The breather pipe that first inlet suction port connects is a right-angle elbow pipe, and the mouth of pipe is provided with downwards; The breather pipe that second inlet suction port connects is a curve bend, and mouth of pipe level inwardly is provided with formation rotary-jet mouth; Blending tank inner chamber middle and lower part is provided with the dressing net that can carry out the filter of secondary comb to mist.
The technical measures of taking also comprise:
Above-mentioned dressing net is for to be worked out by three layers of stainless steel wire dressing net.
The breather pipe that the first above-mentioned inlet suction port connects is a right-angle elbow pipe, and the mouth of pipe is provided with vertically downward.
The breather pipe that the second above-mentioned inlet suction port connects is circular arc bend pipe or oval bend pipe, and mouth of pipe level inwardly is provided with formation rotary-jet mouth.
Compared with prior art, airtight first inlet suction port, second inlet suction port and the pressure switch of being through with in the utility model blending tank tank skin upside, the airtight air outlet adapter that is through with in blending tank tank skin lower side, the airtight drainage valve that is through with in blending tank tank skin lower side; The breather pipe that first inlet suction port connects is a right-angle elbow pipe, and the mouth of pipe is provided with downwards; The breather pipe that second inlet suction port connects is a curve bend, and mouth of pipe level inwardly is provided with formation rotary-jet mouth; Blending tank inner chamber middle and lower part is provided with the dressing net that can carry out the filter of secondary comb to mist.Whole device have novel structure, the stability of a system good, build fast, the precise control of pressure time, when the big flow output of gas; still keep mix uniformly effect; be the safety guard in the magnesium-alloy smelting furnace gas protection system, it also is applicable to multipurpose, the combination of multiple source of the gas.Novel mixing arrangement is rational in infrastructure, makes the combustion-supporting security of magnesium alloy improve greatly, consumes improving the quality of magnesium alloy, reduce to produce, and saves manufacturing cost, has good economic benefit.
Description of drawings
Fig. 1 is the combining structure schematic diagram of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Figure 1, be used for the magnesium alloy efficient gas mixing device, comprise blending tank 5, airtight first inlet suction port 1, second inlet suction port 2 and the pressure switch 3 of being through with in blending tank 5 tank skin upsides, the airtight air outlet adapter 7 that is through with in blending tank 5 tank skin lower sides, the airtight drainage valve 8 that is through with in blending tank 5 tank skin lower sides; The breather pipe that first inlet suction port 1 connects is a right-angle elbow pipe, and the mouth of pipe is provided with downwards; The breather pipe that second inlet suction port 2 connects is a curve bend, and mouth of pipe level inwardly is provided with formation rotary-jet mouth 4; Blending tank 5 inner chamber middle and lower parts are provided with the dressing net 6 that can carry out the filter of secondary comb to mist.Embodiment is that above-mentioned dressing net 6 is for to be worked out by three layers of stainless steel wire dressing net preferably.The breather pipe that first inlet suction port 1 connects is a right-angle elbow pipe, and the mouth of pipe is provided with vertically downward.The breather pipe that second inlet suction port 2 connects is circular arc bend pipe or oval bend pipe, and mouth of pipe level inwardly is provided with formation rotary-jet mouth 4.
Work characteristics and principle:
The utility model operation principle is seen Fig. 1: first kind of gas A injects a small amount of heavy gas such as sulfur hexafluoride SF6 by 1 pair of blending tank of first inlet suction port 5, second kind of gas B passes through gas such as the nitrogen N 2 that 2 pairs of blending tanks of second inlet suction port 5 inject a large amount of light weight slightly after a while, second kind of gas B and first kind of gas A mix by carrying out near the rotary-jet mouth 4 simultaneously the first time, when the mist total amount reaches desired value, the detected pressures switch sends signal, close the prime air-supplying valve, mixing gas tank pressure this moment begins to flow to outbound course, after two gases mix, second stage is carried out the filter of secondary comb through stainless steel wire dressing net 6, after this moment, two kinds of gases were fully mixed the comb filter, overcome disorderly state through combing, finish by air outlet adapter 7 then and carry efficient mist.Drainage valve 8 is when mixed gas tank pressure superelevation, and drainage valve 8 is opened automatically and played purpose of safety.
The utility model utilization principle of hydrodynamics, first kind of earlier that quality is higher gas A injects in the blending tank 5, second kind of gas B that the quality of reinjecting over time is low weight, at this moment input is injected blending tank 5 through rotary-jet mouth 4, the formation high pressure draught carries out fluidised form and rotatablely moves in blending tank 5, first kind of gas A and two kinds of gases of second kind of gas B are admixed.Mix a period of time, carry out the filter of secondary comb by special stainless steel wire dressing net 6 again, first kind of gas A and two kinds of different quality gases of second kind of gas B are mixed full and uniformly, by the size of pressure switch control combined amount, export by air outlet adapter 7, drainage valve 8 at last between mixing period.Mix through such secondary, mix composition and analyze after tested, setting value and actual value maintenance be uniformity preferably.In the production application, combustion-supporting protection is respond well in magnesium-alloy smelting furnace for device, the non-oxidation combustion phenomena, and the scum silica frost rate can be controlled in 0.1%.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
