Description
Technical field
The invention belongs to melting technique fields, are related to a kind of furnace, especially a kind of aluminium melting furnace and application method.
Background technique
Aluminium melting furnace is convenient to carry out melting regeneration to aluminium scrap, such as aluminium ingot is made after some aluminum beverage cans are melted, with side
Just recycling and reusing.But since aluminium scraps of these recycling there may come a time when containing various impurity, for example, stone, soil block, carbon distribution, its
His metal impurities etc. generally use the tool with multiple tooth fork or rake class and are salvaged, and lesser impurity is needed
It wants the density of tooth larger, that is, needs the spacing of tooth smaller, but this meeting is so that tooth can be stained with after coming out in the molten aluminum from melting
Some molten aluminums if molten aluminum, which is splashed down, can bring dangerous or waste, and are left to laugh somebody to scorn after molten aluminum and are set on tooth, are not only unfavorable for
Next time uses, and is also unfavorable for impurity if molten aluminum simultaneously adheres to impurity on tooth and leaves tooth, so usually impurity collecting vessel is not
Can from it is too far, it is necessary to before molten aluminum does not solidify impurity is transferred to impurity collecting vessel after removing in molten aluminum in tooth.If tooth
Spacing then some lesser impurity can then be salvaged to come up greatly very much.
Summary of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, proposing a kind of aluminium melting furnace and application method,
This aluminium melting furnace is convenient for understanding the impurity in molten aluminum, and the space width of fishing device, which can according to need, to be changed.
Object of the invention can be realized by the following technical scheme: including furnace body, furnace body internal upper part is provided with crucible, earthenware
It is burner hearth below crucible, burner hearth is by feeding mechanism connection Bunker, burner hearth bottom and air duct connection, air duct end connection blower,
Fuel in Bunker is biomass granule fuel, and biomass fuel is by stalk, straw, rice husk, peanut shell, corncob, oil tea
The environmentally friendly new energy of bulk that shell, cotton seed hulls etc. and " three surplus objects " are generated by processing.Two impurity are set above the crucible
Salvaging mechanism, impurity salvaging mechanism include bailer grab, and the bailer grab has uniformly distributed blade tooth, and all bailer grabs are connected to latch spoon
On, the axis of the latch spoon connection motor, the motor is controlled the movement in space by Three Degree Of Freedom telescoping mechanism.
When the working principle of this aluminium melting furnace is such that salvage, controlled by Three Degree Of Freedom telescoping mechanism, by two impurity
The bailer grab of salvaging mechanism is extend into molten aluminum, then adjusts the position of two bailer grabs, thus change two bailer grabs that
Relative spacing or angle between this blade tooth, to change the interleaved state of the blade tooth of two bailer grabs, thus according to be beaten
The size and amount of the impurity of fishing are flexibly adjusted, as long as the space width big to biggish impurity, avoids more
Molten aluminum attachment.Since two bailer grabs have blade tooth structure, so that two bailer grabs can be cleared up mutually, especially blade tooth
When spacing is slightly larger than blade tooth, the blade tooth of a bailer grab can the blade tooth to another bailer grab carry out comprehensive surface cleaning.
In above-mentioned aluminium melting furnace, the blade tooth of the bailer grab is the metal material that fusing point is higher than aluminium, and two impurity are salvaged
Mechanism blade tooth is separately connected the two poles of the earth of power supply, and motor shaft connects latch spoon by the connecting rod of insulation.When two impurity salvaging mechanisms
When blade tooth contacts, current lead-through is also beneficial to so that blade tooth is heated so that the aluminium being attached on blade tooth fusing is detached from blade tooth
Impurity is transported to remote position, and only there are two the regions that blade tooth contacts with each other can just be heated, that is to say, that only
The region of carrying impurity can be just heated, and only the region of blade tooth spacing smaller part can be just heated.
Two bailer grabs are reached below the impurity in crucible molten aluminum, two salvagings are adjusted according to the shape of impurity and position
The relative position of pawl, prevent bailer grab from falling from the gap between the blade tooth of bailer grab, is then moved impurity by impurity
At collection, a bailer grab is mobile relative to another bailer grab, so that impurity, which is fallen, leaves bailer grab, salvages if there is being set in
Molten aluminum adhering impurity on pawl when prevent impurity from bailer grab from falling off, is then given in the state that two bailer grabs contact
Conducting wire is powered, so that blade tooth conduction temperature increases, so that the molten aluminum fusing of attachment, so that impurity is detached from bailer grab.
In above-mentioned aluminium melting furnace, the bailer grab is directly connected by a hinge with connecting rod, the bailer grab and connecting rod it
Between connect shape memory alloy spring, when temperature be higher than the shape memory alloy spring phase transition temperature when, spring contraction, when
When temperature is lower than the phase transition temperature of the shape memory alloy spring, spring elongation.The extension and contraction control bailer grab of spring is opposite to be connected
The rotation of bar.
In above-mentioned aluminium melting furnace, the bailer grab is the spherical shell type of a quarter.Shape when two bailer grabs contact relatively
At a hemispheric spoon body, in order to the salvaging to impurity.
In above-mentioned aluminium melting furnace, connecting rod on bailer grab, pull rod one end is connect with bailer grab hinge, the pull rod other end
Hinge connects rocking bar end, and rocking bar rotates by rocking bar motor control, and motor is fixed with respect to latch spoon, rocking bar and pull rod and bailer grab and
Latch spoon constitutes parallelogram lindage.Bailer grab purposes can be made wider in this way, such as can be used for transporting aluminium scrap, as feeding
Manipulator uses, it can also be used to strike off the carbon distribution of crucible internal walls.
By controlling the rotation of rocking bar, to control swinging up and down for bailer grab, which cooperates turning for latch spoon motor again
It is dynamic, change the direction of bailer grab；So that bailer grab is extend into molten aluminum close to crucible internal walls downward, then make bailer grab court again
On pick up impurity, make bailer grab downward impurity be fallen again when bailer grab is moved at impurity collection, if wherein one
Impurity on a bailer grab is not easy to fall, and can adjust another bailer grab and carries out assisting striking off with respect to the position of the bailer grab.
It further include Aluminium ingot mould in above-mentioned aluminium melting furnace, mould housing has cavity, and cavity has air inlet and outlet air
Mouthful, air outlet and fan air inlet connection.The rapid cooling for being not only advantageous to grinding tool also helps the thermal energy of recycling mold, so that
The air of heating enters combustion chamber, is conducive to the temperature for improving burning.
Compared with prior art, this aluminium melting furnace and application method have the advantage that
Aluminium melting furnace of the invention not only can also be had a set of convenient for removal of impurities convenient for being burnt using biomass granule fuel
Equipment so that removal of impurities is more convenient, avoiding the attachment of molten aluminum from bonding influences removal of impurities, wastes molten aluminum, simultaneously can be used for pair
The cleaning of crucible carbon distribution is used as feeding manipulator, is also helped the rapid cooling of grinding tool and is recycled the thermal energy of mold, knot
Structure is simple, easy to operate, at low cost.
