Description
Technical field
The utility model belongs to magnesium alloy casting equipment technical field, and in particular to a kind of protection cast for smelting furnace
The distributing cabinet of gas.
Background technology
The chemical property of magnesium is active, is easily reacted with the oxygen in air, the magnesium alloy chemical property of liquid is more living
Sprinkle, a contact oxygen will burn, so that the surface of spindle will produce one layer of oxide skin, influence product quality, and in low pressure
In metaideophone production process, it is desirable to compressed air must be passed through in stove, magnesium alloy fused mass press against by the air pressure of compressed air, lead to
Cross pipette and complete cast, particularly if the section of magnesium-alloy smelting furnace is relatively wide, it is easy to occur during low pressure metaideophone
Burning, causes the product surface of production honeycomb-like pores occur；Also, because the atmospheric pressure value required for liquid level is relatively wide is relative
It is higher and more to stablize, it is therefore desirable to add the mixed gas of a certain amount of sulfur hexafluoride and carbon dioxide in atmosphere,
To protect the liquid level of magnesium alloy solution, the quality of product is improved.
The content of the invention
The purpose of this utility model is to solve prior art to there is magnesium alloy liquid level protecting effect difference and without special equipment
Technical problem is there is provided a kind of distributing cabinet for the protective gas cast for smelting furnace, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of distributing cabinet for the protective gas cast for smelting furnace of the utility model, it is wrapped
Include cabinet；Its main points is that the bottom of the cabinet is provided with booster jar, and the side of booster jar is provided with the compressed air with pressure-reducing valve
Air inlet pipe；The mixed gas tank being interconnected with booster jar is provided with the cabinet；The mixed gas tank respectively with CO2Air inlet
Pipe and SF6Air inlet pipe is interconnected；The CO2Air inlet pipe and SF6CO is respectively equipped with air inlet pipe2Flowmeter and SF6Flowmeter；Institute
The opposite side for stating booster jar is interconnected by the pipe of collaborating with pressure charging valve with mixed gas escape pipe.
It is preferred that, the CO2Air inlet pipe and SF6Same one end of air inlet pipe is placed in the inside of mixed gas tank, and CO2Air inlet
Pipe and SF6Some ventholes are uniformly provided with the tube wall of air inlet pipe respectively.
It is preferred that, the pipe of collaborating of pressure charging valve is carried between the booster jar and mixed gas escape pipe provided with 1-3 roots.
The utility model reasonable in design, easy to use, CO2Air inlet pipe and SF6Air inlet pipe is respectively into mixed gas tank
Injection gas is mixed, and is entered back into and is mixed in booster jar with compressed air, is entered finally by mixed gas escape pipe
In body of heater；CO2Air inlet pipe and SF6Venthole is uniformly provided with air inlet tube wall can ensure that two kinds of gases are obtained in mixed gas tank
To fully complete mixing；Pipe of collaborating is provided with 1-3 roots, and pressure charging valve is designed with every, and the stream of gas can be adjusted as needed
Amount, it is ensured that pressure it is continual and steady.The utility model solves prior art magnesium alloy liquid level protecting effect difference and without special
The technical problem of equipment.

Embodiment
Reference picture 1, the utility model it include cabinet 12；The bottom of the cabinet 12 is provided with booster jar 8, and booster jar 8
Side be provided with the compressed air inlet pipe 6 with pressure-reducing valve 7；The mixing being interconnected with booster jar 8 is provided with the cabinet 12
Gas tank 5；The mixed gas tank 5 respectively with CO2Air inlet pipe 1 and SF6Air inlet pipe 2 is interconnected；The CO2The He of air inlet pipe 1
SF6CO is respectively equipped with air inlet pipe 22Flowmeter 3 and SF6Flowmeter 4；The opposite side of the booster jar 8 passes through with pressure charging valve 9
Collaborate pipe 13 and mixed gas escape pipe 11 be interconnected.
The CO2Air inlet pipe 1 and SF6Same one end of air inlet pipe 2 is placed in the inside of mixed gas tank 5, and CO2The He of air inlet pipe 1
SF6Some ventholes are uniformly provided with the tube wall of air inlet pipe 2 respectively.
The pipe 13 of collaborating of pressure charging valve 9 is carried between the booster jar 8 and mixed gas escape pipe 11 provided with 1-3 roots.
Cabinet 12 in the utility model is welded into steel plate and iron sheet, CO2Air inlet pipe 1 and SF6Air inlet pipe 2 is all
It is made up of common iron pipe, and is placed on the CO inside mixed gas tank2Air inlet pipe 1 and SF6It is average in air inlet pipe 2 to be bored every 3mm
Four eyes are bored in one eye, each section, and the size of drill bit is 0.5mm, is easy to the mixing of two kinds of gas.
Workflow：Pass through CO2Air inlet pipe 1 and SF6Air inlet pipe 2 injects gas into mixed gas tank 5, by observing CO2
Flowmeter 3 and SF6The reading of flowmeter 4 adjusts flow, passes through pressure-reducing valve 7 and controls the flow of compressed air inlet pipe 6 to enter
In booster jar 8, first pass through a pipe 13 of collaborating and connected with mixed gas escape pipe 11, the reading of pressure gauge 10 is observed, according to reading
Number takes the circumstances into consideration selection and opens other escape pipes 13 again, and the reading for ensureing pressure gauge 10 maintains gas all the time at 0.03-0.06 MPas
The stabilization of pressure, it is ensured that the continuity of casting process.
After the utility model is implemented, the problem of flow velocity is unstable in casting process is solved, is solved in casting process
Pot wall is because magnesium liquid oxidation burning causes pot wall dross, and the problem of clear pot is difficult solves asking for product surface honeycomb-like pores
Topic.
