As described above, in connection with FIG. 1, the present invention provides an apparatus for continuously producing a foamed aluminum rod material, which includes a holding furnace 10, an automatic blowing unit 20, and a mold 30;
the heat preservation furnace 10 is used for containing aluminum liquid, the heat preservation furnace 10 can heat the aluminum liquid to enable the aluminum liquid to keep a melt state, specifically, as an optional method for the heat preservation of the heat preservation furnace 10, a heating module is arranged on the outer wall of the heat preservation furnace 10, and the power of the heating module is dynamically adjusted by measuring the temperature of the aluminum liquid in the heat preservation furnace 10, so that the aluminum liquid in the heat preservation furnace 10 is guaranteed to keep a molten state for standby.
The automatic air blowing unit 20 is provided with an air blowing pipe 21 for blowing air into the aluminum liquid to generate aluminum liquid foam; the mould 30 has a first opening 31 for housing the path of upward migration of the molten aluminum foam and a second opening 32 for removal of the shaped aluminum foam rod 1 from the mould 30.
In the technical scheme provided by the invention, after the air blowing pipe 21 of the automatic air blowing unit 20 blows air into the aluminum liquid to generate aluminum liquid foam, the aluminum liquid foam floats upwards and enters the die 30, is continuously pushed into the die 30 under the action of subsequent aluminum liquid foam, gradually starts to be cooled and formed in the process, is restrained and formed into the foamed aluminum bar 1 through the second opening 32 of the die 30, and continuously moves towards the direction far away from the die 30, so that the foamed aluminum bar 1 is continuously formed.
According to the device provided by the invention, the length of the die 30 can be prolonged to meet the requirement of cooling and forming the foamed aluminum bar, but in order to avoid the second opening 32 of the die 30 being arranged too far and causing the body of the die 30 to be too long, the cooling device 40 is arranged at the second opening 32 of the die 30 for cooling the molten aluminum foam to promote the molten aluminum foam to be rapidly shaped to obtain the foamed aluminum bar.
Further preferably, in the present invention, in order to ensure uniform cooling, the cooling device 40 is arranged along the circumferential extension of the second opening 32.
According to the device provided by the invention, in order to promote the cooled and formed foamed aluminum bar to continuously and stably move towards the direction away from the die 30 so as to realize better continuous production of the foamed aluminum bar, the device further comprises a traction assembly 50, wherein the traction assembly 50 is provided with a plurality of groups of traction rollers 51 which are arranged in parallel at intervals and used for clamping and drawing the formed foamed aluminum bar 1 away from the die 30.
In a particular embodiment of the invention, the drawing assembly 50 comprises two sets of drawing rollers 51 spaced apart in the direction of discharge of the die 30; further preferably, the rotation axis core lines of the two sets of pulling rollers 51 are at an included angle, so that the holding clamp for the formed foamed aluminum bar 1 can be realized by the two sets of pulling rollers 51, the foamed aluminum bar 1 is prevented from toppling, and more preferably, the rotation axis core lines of the two sets of pulling rollers 51 are 90 °. (Note that the axes of rotation of the two sets of pulling rolls 51 do not lie in the same plane, but are angled from a top view.)
According to the device provided by the invention, the heat preservation furnace 10 is internally provided with a partition plate 11 for partitioning the heat preservation furnace into a liquid storage chamber 101 and a foaming chamber 102, wherein the upper end of the liquid storage chamber is partitioned and the lower end of the liquid storage chamber is communicated; the lower end of the blowing pipe 21 is inserted into the foaming chamber 102 for generating aluminum liquid foam.
A height monitoring probe 103 is arranged above the liquid storage chamber 101 and used for monitoring the liquid level height of the aluminum liquid in the liquid storage chamber 101.
In the invention, in order to realize the continuous production of the foamed aluminum bar 1, aluminum liquid needs to be continuously supplemented into the holding furnace 10, but in the traditional process for producing foamed aluminum by using a blowing method, the aluminum liquid foam exists above the liquid level of the aluminum liquid, so that the height monitoring probe 103 is difficult to judge the height of the aluminum liquid in the holding furnace 10 at present, and further the automatic liquid supplementing device cannot be indicated to supplement the liquid in the holding furnace 10, in some existing production processes, middle-section blowing is forced to judge the aluminum liquid in the holding furnace 10, and further the production middle section is caused, and the storage efficiency is influenced. In the technical scheme provided by the invention, the insulation board 11 is arranged in the heat preservation furnace 10, and the insulation board 11 is characterized in that the heat preservation furnace 10 is divided into a liquid storage chamber 101 and a foaming chamber 102, wherein the upper end of the liquid storage chamber 101 is separated from the lower end of the foaming chamber 102, and the lower end of the air blowing pipe 21 is inserted into the foaming chamber 102 to blow air so as to generate aluminum liquid foam; when the amount of the aluminum liquid in the holding furnace 10 is reduced, the liquid levels in the liquid storage chamber 101 and the foaming chamber 102 are synchronously reduced, the blowing foaming process of the aluminum liquid is carried out in the foaming chamber 102, and the aluminum liquid foam floating on the liquid level cannot be generated in the liquid storage chamber 101, so that whether the amount of the aluminum liquid in the holding furnace 10 is lower than the set amount can be accurately judged through the height monitoring probe 103 arranged above the liquid storage chamber 101. If the liquid storage chamber 101 is monitored, namely the stock of the aluminum liquid in the heat preservation furnace 10 is lower than the set amount, a signal can be sent to the automatic liquid supplementing device to supplement the liquid to the liquid storage chamber 101, and in the liquid supplementing process, due to the existence of the isolation plate 11, the surge impact generated in the liquid supplementing process cannot influence the process of blowing air in the foaming chamber 102 to form the aluminum liquid foam, specifically, the influence on the size and the amount of the aluminum liquid foam is avoided, and the quality of the foamed aluminum rod material 1 is further ensured.
In a specific embodiment of the present invention, the aperture of the first opening 31 of the mold 30 is larger than the aperture of the second opening 32, and the mold body from the first opening 31 to the second opening 32 is in an arc shape protruding outwards. In particular, an inverted and vertically through bowl-like structure such as that shown in fig. 1. The aperture of the first opening 31 is set to be large enough to ensure that the aluminum liquid foam generated by blowing air from the blowing pipe 21 is sufficiently collected in the mold 30 for utilization.
In the present invention, the profile of the second opening 32 is the cross-sectional profile of the aluminum foam bar 1 to be formed. In order to obtain the foamed aluminum bars 1 with different cross-sectional shapes, the outline of the second opening 32 is round, square, semicircular, triangular or other special shapes; the other shapes include a combination of a semicircle and a triangle, and the like.
In the invention, the method for continuously producing the foamed aluminum bar by the device comprises the following steps: melting aluminum or aluminum alloy to form aluminum liquid, adding silicon carbide particles, stirring and tackifying, and pouring the tackified aluminum liquid into a heat preservation furnace 10 for heat preservation for later use;

Further, in the above method, the conditions of blowing air into the molten aluminum by the automatic air blowing unit 20 include: the compressed air flow is 0.2-0.3L/min, and the pressure is 0.2-0.3 MPa.
The foregoing shows and describes the general principles, essential features, and inventive features of this invention.
