Thus, through this embodiment, the aluminum alloy liquid melted in the melting furnace (the previous device) enters the runner well 1 from the liquid inlet channel 3, the runner well 1 is empty initially, the liquid enters the runner well 1 downward under the action of gravity after entering from the liquid inlet channel 3, the liquid is not discharged at this time, the liquid level gradually rises, and after the liquid level of the liquid reaches the height of the liquid outlet channel 4, the liquid in the runner well 1 flows out from the runner well 1 through the liquid outlet channel 4. Then, the flow velocity of the liquid entering the runner well 1 from the liquid inlet channel 3 and the flow velocity of the liquid flowing out of the runner well 1 are controlled to be equal, so that the liquid level in the runner well 1 is kept stable. At this time, the smooth liquid surface of the runner well 1 is located between the top and bottom of the partition, and the liquid surface does not go over the top of the liquid inlet channel 3 and the top of the liquid outlet channel 4.

After the liquid level of the fluid is stable in the runner well 1, the electromagnetic inductor is electrified, the electromagnetic inductor generates a plurality of orange-shaped (similar to the shape of the earth magnetic field) magnetic fields (traveling wave magnetic fields), the magnetic field directions are vertical (the magnetic field directions are vertical and can be realized through the arrangement positions of the iron cores, for example, according to the right-hand spiral rule principle, the direction of the thumb is vertical, at the moment, the N pole and the S pole generated by the electromagnet are vertically distributed, so that the produced magnetic field is vertical), the liquid in the runner well is stirred in the vertical direction under the action of the magnetic field, for example, as shown in fig. 4, the size and the vertical direction of the magnetic field force of the electromagnetic inductor can be changed by controlling the corresponding frequency converter through changing the current, the frequency and the phase sequence of the variable-frequency power supply, so that the size and the direction of the stirring force of the liquid are changed, the phenomenon of turbulent flow is caused or the degree of turbulent flow is controlled.

The liquid in this embodiment flows from the liquid outlet 4 to the heat preservation furnace (next device), after standing in the heat preservation furnace, slag in the liquid is subjected to slag beating operation, therefore, through this embodiment, the feeding in the smelting furnace is not needed, an online feeding mode is adopted, the traditional feeding mode is changed, the liquid in the smelting furnace can be fed and mixed in the transferring process of the liquid to the heat preservation furnace, the whole process can not occupy the transferring time of the fluid, and meanwhile, the feeding and mixing processes can not occupy the smelting of the metal in the smelting furnace, and because the feeding in the smelting furnace is not needed, the liquid is not needed to be transferred after standing in the smelting furnace, the idle state of the smelting furnace during standing in the smelting furnace is avoided, the utilization efficiency of the heat preservation furnace and the smelting furnace is improved, the time of fluid purification and transfer is greatly saved, and the whole production and manufacturing efficiency are improved. Meanwhile, the smelting furnace can not be provided with a larger furnace door or the furnace door is opened to a larger degree by adopting a mechanical stirring mode, so that heat loss and energy waste are reduced.

Of course, the bottom of the runner well 1 can be provided with a drain pipe, and a valve is arranged on the drain pipe, so that the valve is in a closed state when the runner well 1 is used normally, and the liquid can maintain the normal liquid level in the runner well 1.

The vertical agitation is preferred in this embodiment because the vertical agitation is relatively wide in the range of agitation, enabling the input material and the liquid to be sufficiently mixed.

The arrangement of the magnetic field direction, the magnetic field size and the like can also be realized by different shapes of electromagnetic inductors, coil winding modes and numbers and the numbers of the electromagnetic inductors.

The magnetic field generated by the electromagnetic inductor is mainly utilized to stir the liquid, so that the stirring of the liquid is realized, the stirring dead angle problem can not occur compared with mechanical stirring, and the mixing and stirring efficiency and effect are improved.

Example 2

The embodiment is improved on the basis of embodiment 1, and as shown in fig. 1 and 2, the inside of the runner well 1 is fixedly provided with vertical separation parts, the separation parts are specifically plate-shaped structures, the top of the liquid inlet channel 3 and the top of the liquid outlet channel 4 are lower than the top of the separation parts, and the bottom of the liquid inlet channel 3 and the bottom of the liquid outlet channel 4 are higher than the bottom of the separation parts. The partition in this embodiment includes a first partition 6 and a second partition 7, the first partition 6 and the second partition 7 are welded on the inner wall of the flow path well 1, the first partition 6 and the second partition 7 are symmetrically disposed in this embodiment, and the connection line of the first partition 6 and the second partition 7 transversely divides the interior of the flow path well 1 into a strong stirring zone 2 and a weak stirring zone 5 which are mutually communicated, because the bottoms of the partitions do not abut against the bottoms of the flow path well 1, the strong stirring zone 2 and the weak stirring zone 5 are in a communicating state. The partition in this embodiment is formed of two left and right parts, i.e., the first partition 6 and the second partition 7, but of course, in other embodiments, the left and right parts may be integrally connected. The volume of the strong agitation area 2 is larger than the volume of the weak agitation area 5 in this embodiment.

The runner well 1 is provided with a slag hole which is opposite to and communicated with the weak stirring area 5, and the slag hole can be arranged at the top of the runner well 1 or the position of the side wall of the runner well 1 close to the top end. The liquid inlet channel 3 is connected to the side wall of the strong stirring area 2, the liquid inlet direction of the liquid inlet channel 3 points to the inner wall of the strong stirring area 2, and further, the liquid inlet channel 3 is connected to the connecting part of the side wall of the strong stirring area 2 and the side wall of the weak stirring area 5, and the liquid inlet direction of the liquid inlet channel 3 points to the inner wall of the strong stirring area 2. In addition, the liquid outlet 4 in this embodiment is connected at another connection point of both the side wall of the strong agitation area 2 and the side wall of the weak agitation area 5.

The electromagnetic inductors in this embodiment are two groups, specifically, the electromagnetic inductors include a first electromagnetic inductor 11 and a second electromagnetic inductor 12, and the first electromagnetic inductor 11 and the second electromagnetic inductor 12 are both arc-shaped, so as to adapt to the arc-shaped outer wall of the runner well 1. The volume of the first electromagnetic inductor 11 is larger than that of the second electromagnetic inductor 12, the first electromagnetic inductor 11 is positioned on the outer side of the side, provided with the strong stirring area 2, of the runner well 1, and the second electromagnetic inductor 12 is positioned on the outer side of the side, provided with the weak stirring area 5, of the runner well 1. Since the volume of the first electromagnetic inductor 11 is larger than the volume of the second electromagnetic inductor 12, the first electromagnetic inductor 11 is disposed below the second electromagnetic inductor 12. The first electromagnetic inductor 11 and the second electromagnetic inductor 12 are respectively connected with frequency converters.

Therefore, after the liquid level of the fluid is stable in the runner well 1, the first electromagnetic inductor 11 and the second electromagnetic inductor 12 are electrified, the electromagnetic inductors generate a plurality of orange-shaped magnetic fields (traveling wave magnetic fields) similar to the shape of the earth magnetic field, the magnetic field directions are vertical, the liquid in the runner well is stirred (stirring directions are all stirring in the vertical direction) under the action of the magnetic field, and the magnitude and the direction of the magnetic field force of the first electromagnetic inductor 11 and the second electromagnetic inductor 12 can be changed by controlling the corresponding frequency converter through changing the current, the frequency and the phase sequence of the frequency conversion power supply, so that the magnitude and the direction of the liquid stirring force are changed, the phenomenon of turbulent flow is caused or the degree of turbulent flow is controlled. The direction of the magnetic field for the first electromagnetic inductor 11 and the second electromagnetic inductor 12 may be the same or opposite depending on the actual stirring requirements.

In this embodiment, the first electromagnetic sensor 11 is far from the weak agitation area 5, the second electromagnetic sensor 12 is small in volume, and the generated magnetic field acting force is small under the condition that other parameters are the same, such as the current frequency and the magnitude parameter are the same, so that the electromagnetic effect of the second electromagnetic sensor 12 near to the weak agitation area 5 on the liquid in the weak agitation area 5 is small, and the liquid in the weak agitation area 5 can maintain relative stability. The first electromagnetic inductor 11 has larger volume and larger magnetic field acting force, so that the first electromagnetic inductor 11 has large electromagnetic action on the liquid in the strong stirring area 2, the liquid in the strong stirring area 2 can be sufficiently stirred, and the first electromagnetic inductor 11 is far away from the weak stirring area 5 and cannot have larger electromagnetic action on the weak stirring area 5.

In this way, the electromagnetic stirring degree of the liquid in the strong stirring area 2 is greater than that of the liquid in the weak stirring area 5, so after the granular refining agent and/or gas (argon or chlorine) is added into the strong stirring area 2 of the runner well 1, the refining agent and/or gas is fully mixed with the fluid under the electromagnetic stirring effect.

The added refining agent (or gas) can react with impurities in the liquid to form a part of slag, and the chlorine can react with alkali metals such as sodium, potassium, calcium and the like in the aluminum alloy melt. By introducing argon gas into the runner well 1, hydrogen gas in the aluminum alloy melt in the runner well 1 can be extruded.

Because the electromagnetic stirring degree that weak stirring district 5 received is less, the liquid level in weak stirring district 5 is comparatively steady, consequently the formation of a portion sediment in the aluminum alloy fuse-element is spread easily and is floated and enter weak stirring district 5, the sediment is easy to gather in weak stirring district 5, then carry out the sediment processing of beating through the slag notch to the sediment that floats on the liquid surface (through manual control beating the sediment instrument or use the sediment machine to drive beating the sediment board and get into weak stirring district 5 through the slag notch and beat the sediment), perhaps indirect carry out the sediment processing of beating with the sediment on the liquid surface in the weak stirring district 5 (with the sediment in the weak stirring district 5 introduce into beating the sediment pond 10 through the slag notch, then manual control beating the sediment instrument or use the sediment machine to drive beating the sediment in the sediment pond 10 and beat the sediment again), thereby be favorable to reducing the sediment volume in the holding furnace, improve the effect of purifying.

Example 3

Of course, in order to make the mixing and stirring of the liquid in the strong stirring area 2 more sufficient, the feeding portion in this embodiment may also include a graphite rotor shaft 9, the bottom of the rotor shaft 9 is provided with a rotor turntable 8, the top of the rotor shaft 9 is provided with an inlet, the bottom of the rotor shaft 9 is provided with an outlet, and the interior of the rotor shaft 9 is hollow. In this way, the refining agent or gas (mainly gas, particle powder refining agent is added through a feeding hopper) is added into the rotor shaft 9 through the inlet, the gas enters the runner well 1 along the rotor shaft 9, the rotor shaft 9 is driven to rotate through the motor outside the device, and the rotor shaft 9 drives the rotor turntable 8 to stir liquid, so that the refining agent and/or gas is mixed with fluid and reacts more fully. Of course, the stirring direction of the rotor shaft 9 can be opposite to the rotation direction of the fluid vortex, so that the cutting of the fluid by the rotor turntable 8 is increased, which is beneficial to the turbulence of the liquid and further ensures that the refining agent and/or gas are mixed and react with the fluid more fully.

Because the volume of runner well 1 is less than the volume of smelting furnace, therefore rotor shaft 9 in this embodiment is in normal position rotation, need not to set up other structures and make its horizontal or vertical removal and enlarge stirring area, and the simple structure of feeding portion, runner well 1 opening need not set up great to reduce the loss of heat.

Example 4

As shown in fig. 1 and 2, in other embodiments, the outer ring 13 of stainless steel is sleeved outside the runner well 1, and at this time, the outer ring 13 is regarded as the outer wall of the runner well 1, and the runner well 1 is formed by pouring stainless steel or casting materials. The heat insulation material (such as aluminum silicate or nano heat insulation material) is filled between the outer ring 13 and the side wall of the runner well 1, the heat insulation material between the outer ring 13 and the side wall of the runner well 1 is a heat insulation layer 14, and the heat insulation layer 14 is arranged to insulate the aluminum alloy melt in the runner well 1, so that the temperature of the aluminum alloy melt is not lower than the melting point. Of course, a heating rod may be provided in the runner well 1 to heat the aluminum alloy melt so that the temperature of the aluminum alloy melt is not lower than the melting point.

The thicknesses of the runner well 1, the outer ring 13 and the heat insulation layer 14 in the embodiment can be set according to practical situations, for example, when the runner well 1 is made of castable, the thickness of the outer ring 13 can be 5-8mm, the thickness of the heat insulation layer 14 can be 20-30mm, and the thickness of the runner well 1 can be 70-90mm; when the runner well 1 is made of stainless steel, the thickness of the runner well 1 can be reduced and the thickness of the heat insulating layer 14 can be increased, compared with when the runner well 1 is made of castable.

Example 5

The magnetic fields generated by the electromagnetic sensors in example 2 are all vertical. When two groups of electromagnetic inductors are adopted in the embodiment, the electromagnetic inductor above can also generate a transverse magnetic field, and the electromagnetic inductor below generates a vertical magnetic field, and the specific implementation mode can be as follows: the magnetic field is mainly vertically distributed at the two ends of the N pole and the S pole of the iron core, the direction of the thumb of the upper electromagnetic inductor is transverse, and the two ends of the N pole and the S pole of the iron core are transversely distributed.

Like this the liquid of runner well below receives vertical magnetic field force and vertical roll, agitate, and the liquid that is located runner well top receives horizontal magnetic field force and horizontal roll, agitate, and the liquid receives horizontal and vertical electromagnetism simultaneously and agitates, agitates the direction more three-dimensional, agitates, mixes more abundant for turbulent effect is better.

For the transverse direction, the transverse direction can be the transverse direction of the straight line direction or the transverse direction of the rotating direction, which can be realized by the iron core arrangement mode of the electromagnetic inductor above, the mode that the frequency converter controls whether each coil in the electromagnetic inductor is electrified, the electrifying direction and the size, and the like, when the transverse direction is the rotation, for example, as shown in fig. 3, the transverse stirring of the liquid can be caused to generate vortex, the liquid is favorably turbulent, and the stirring effect is improved.
