Technical field
The utility model relates to foundary industry heavy castings fixed point cast blowing and drawing type enclosure, specifically refers to a kind of fixed point cast blowing and drawing type enclosure, is applicable to the enclosure in the heavy castings cast.
Background technology
At present, capture mode to the casting area's flue gas in the foundary industry mainly contains two kinds: first kind is to carry out the general ventilation ventilation in the casting area operating area, the flue gas that the discharge cast is distributed and a large amount of waste heats, this mode exists systematic air flow big, the energy consumption height, and the working region smoke discharging effect is undesirable, shortcomings such as cast regional environment difference; The second way adopts the side-draught hood smoke evacuation, and namely side-draught hood is arranged in sandbox one side, and this mode only is applicable to the cast of small-sized foundry goods, and the cover mouth is poor away from pour point and smoke discharging effect.
The utility model content
The purpose of this utility model is to provide a kind of flue gas trapping rate height at the deficiencies in the prior art, and exhaust smoke level is little, and the fixed point cast blowing and drawing type enclosure of energy-saving safe is applicable to the cast of heavy castings fixed point.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of fixed point cast blowing and drawing type enclosure, comprise cover body, exhaust opening, the up-draught cover, blower fan, canyon cover and control valve, described cover body is that three side sealing closes and the obturator of upside and front openings, described cover body is wrapped in outside the sandbox, the rear side of described cover body is provided with the exhaust opening that is communicated with fume extractor, the upside of described cover body is equipped with the up-draught cover that is connected with blower fan, the installed in front of described cover body has the canyon cover that is connected with blower fan, described up-draught cover is provided with spout at least one, described canyon cover is provided with at least one spout down, and the described angle that goes up the air outlet of spout and following spout makes the described spout of going up induce flue gas to move towards the direction of described exhaust opening with the wind that following spout blows out.
Described up-draught cover comprises upper left blowing cover and upper right blowing cover, described upper left blowing cover and upper right blowing cover are symmetricly set on the upper end of the described cover body left and right sides, described canyon cover comprises lower-left blowing cover and bottom right blowing cover, described lower-left blowing cover and bottom right blowing cover are symmetrical arranged on the two sides of described cover body front end, described upper left blowing cover and lower-left blowing cover are connected with first blower fan by pipeline, and described upper right blowing cover and bottom right blowing cover are connected with second blower fan by pipeline.
Described upward spout and described spout down are the scrak type spout.
The described spout of going up comprises on first spout on the spout and second, described spout down comprises first time spout and second time spout, the angle of spout and horizontal plane is 0 degree～-15 degree on described first, the angle of spout horizontal plane is 0 degree～-15 degree on described second, the angle of described first time spout and horizontal plane is 0 degree～50 degree, and the angle of described second time spout horizontal plane is 0 degree～50 degree.
The described adjustable angle joint of going up spout and described spout down.
In the heavy castings casting process, produce a large amount of high temperature dust flue gases, main source has: one, during steel ladle pouring, discharge a large amount of high temperature dust flue gases from sandbox pore and slit; Two, the ladle top opening is because high temperature is discharged the high temperature dust flue gas.The wind guiding that this device utilizes up-draught cover and canyon cover that blower fan is come out, the high temperature dust flue gas that one side is discharged from sandbox pore and slit, induce the change direction to cause exhaust opening through canyon cover jet, on the other hand, from the high temperature dust flue gas that the ladle mouth is discharged, induce the change direction to cause exhaust opening through up-draught cover jet; Thereby prevented that the high temperature dust flue gas from revealing from enclosure, and energy-saving safe.And the angle that this device is gone up spout and following spout can regulate, and convenience is regulated the direction of wind according to actual conditions, makes smoke discharging effect better.
In sum, this device capture rate height, exhaust smoke level is little, and energy-saving safe is applicable to the cast of heavy castings fixed point.
