Technical Field

[0001] The invention relates to the technical field of aluminum profile production, and in particular to energy-saving melting furnace equipment for aluminum profile production. Background Art

[0002] During the smelting production process of aluminum profiles, incomplete smelting is prone to occur due to the large temperature difference between the newly added aluminum raw materials and the aluminum liquid. As a result, it is easy to deposit at the bottom of the aluminum liquid during the smelting process, causing accumulation and further increasing the difficulty of smelting, thereby forming aluminum slag that affects the smelting quality. Therefore, the aluminum slag needs to be cleaned in time.

[0003] After searching, the patent technology with announcement number CN218179614U discloses a furnace for processing industrial aluminum profiles, including a shell, a fixed plate is fixed on the bottom of the outer wall of the shell, a first rotating shaft is rotatably installed inside the fixed plate, and a servo motor is fixed on the lower end of the first rotating shaft. The furnace for processing industrial aluminum profiles can drive the cover plate and the filter to move upward by starting the cylinder, so that the filter can filter out all the impurities in the aluminum solution without the need for workers to scoop them out, thereby improving work efficiency and safety. Starting the servo motor to rotate 180 degrees can swap the positions of the two filters, thereby facilitating the replacement of the filters without increasing the time for cleaning the filters, thereby improving work efficiency. When the furnace is working, the used filters can be removed and cleaned, thereby not occupying the time of the furnace for processing aluminum raw materials.

In addition, because the thread direction of the second auger is opposite to that of the first auger, when the first auger spirally transports the slag on the inner side of the bottom of the first guide pipe upward, the second auger can guide the aluminum raw material particles in the receiving hopper into the crucible through the curved pipe for smelting. Compared with the prior art, the present invention can realize feeding and assisting the discharge of aluminum slag at the same time. During the up-and-down lifting movement of the upper pressure plate outside the first shaft rod of the present invention, the pouring bed can be pushed and pulled back and forth by the thrust rod. Due to the hinged relationship between the end of the pouring bed and the receiving hopper, the pouring bed can be continuously shaken, which is beneficial for pouring the aluminum raw material particles on the expanding section and the shrinking section into the receiving hopper, thereby avoiding the accumulation of materials on the pouring bed and causing blockage. At the same time, since the pouring bed is suspended above the slag collecting hopper, the aluminum slag accumulated on the slag collecting hopper has residual temperature. Compared with the prior art, the present invention can heat-dry the rolled aluminum raw material particles by the residual temperature of the aluminum slag, so as to reduce the temperature difference between the aluminum material and the molten aluminum liquid and improve the utilization efficiency of the residual heat.

Under the transmission action of the transmission belt 45, the second shaft 84 is driven to rotate through the second pulley 44, and the direction of the first shaft 52 is the same as the direction of the second shaft 84. Because the thread direction of the second auger 85 is opposite to that of the first auger 53, when the first auger 53 spirally transports the slag on the inner side of the bottom of the first guide pipe 51 upward, the second auger 85 can guide the aluminum raw material particles in the receiving hopper 83 through the curved pipe 82 to the crucible 2 for smelting.

A pressure cover 103 is fixed to the outer side of the upper pressing plate 101. The pressure cover 103 is a conical structure, and the taper is consistent with the filter screen plate 7. During the rotation of the first shaft 52, the lower pressing plate 56 can be driven to rotate synchronously. Since the upper pressing plate 101 is subjected to the thrust rod 104, the lower pressing plate 56 can rotate synchronously. The hinge restriction cannot rotate with the first shaft rod 52, and then the first arc-shaped pressing block 57 presses the second arc-shaped pressing block 102 to make the upper pressure plate 101 move up and down outside the first shaft rod 52, and then the pressure cover 103 outside the upper pressure plate 101 presses the aluminum slag accumulated on the filter mesh plate 7 and the slag collecting bucket 6 back and forth up and down, so that the aluminum liquid in the aluminum slag can be fully squeezed out, and a furnace door is set on the side of the furnace body 1 to regularly clean the slag on the filter mesh plate 7 and the slag collecting bucket 6.

At the same time, since the pouring bed 9 is suspended above the slag collecting hopper 6, the aluminum slag accumulated on the slag collecting hopper 6 has residual temperature, and the residual temperature of the aluminum slag can be used to heat the falling aluminum raw material particles.

[0027] See also Figure 2 , Figure 3A feed hopper 11 leading to the expanded section 91 is fixed on the top of the furnace body 1. During the smelting process, the top opening of the feed hopper 11 is sealed by a sealing cover to reduce heat loss.

[0028] The working principle and use process of the present invention are as follows: the aluminum raw material particles in the crucible 2 are smelted under the high temperature environment in the furnace body 1, and the aluminum slag produced by the smelting is deposited to the bottom by gravity and enters the first guide pipe 51 through the feed port 54, and the motor 3 drives the first shaft 52 to rotate under the meshing of the first bevel gear 41 and the second bevel gear 42, and then the first auger 53 outside the first shaft 52 spirally transports the slag on the inner side of the bottom of the first guide pipe 51 upward, and in the process of spiral ascent after exceeding the crucible 2, the slag can be initially filtered by the filter screen cylinder 55 at the top of the first guide pipe 51, and then discharged from the top of the first guide pipe 51 and scattered on the filter screen plate 7, and secondary filtration is performed in the process of rolling on the filter screen plate 7, so that the aluminum liquid remaining on the aluminum slag can be introduced into the crucible 2 through the slag collecting bucket 6 after filtration; During the rotation of the first shaft 52, the lower pressure plate 56 can be driven to rotate synchronously. Since the upper pressure plate 101 is restricted by the hinge of the thrust rod 104 and cannot rotate with the first shaft 52, the first arc-shaped pressure block 57 can press the second arc-shaped pressure block 102 to make the upper pressure plate 101 move up and down outside the first shaft 52, and the pressure cover 103 outside the upper pressure plate 101 can press the aluminum slag accumulated on the filter screen 7 and the slag collecting bucket 6 up and down to make the aluminum liquid in the aluminum slag be fully squeezed out. During the rotation of the first shaft 52, the first pulley 43 can also be driven to rotate. Under the transmission action of the transmission belt 45, the second shaft 84 is driven to rotate through the second pulley 44. The direction of the first shaft 52 is the same as that of the second shaft 84. Since the thread direction of the second auger 85 is opposite to that of the first auger 53, when the first auger 53 spirally transports the slag on the inner side of the bottom of the first guide pipe 51 upward, the second auger 85 can guide the aluminum raw material particles in the receiving hopper 83 through the curved pipe 82 into the crucible 2 for smelting. During the process of the upper pressure plate 101 making up and down lifting movements outside the first shaft rod 52, the pouring bed 9 can be pushed and pulled back and forth by the thrust rod 104. Due to the hinged relationship between the end of the pouring bed 9 and the receiving hopper 83, the pouring bed 9 can be continuously shaken, which is conducive to pouring the aluminum raw material particles on the expanding section 91 and the shrinking section 92 into the receiving hopper 83, avoiding the accumulation of materials on the pouring bed 9 and causing blockage. At the same time, since the pouring bed 9 is suspended above the slag collecting hopper 6, the aluminum slag accumulated on the slag collecting hopper 6 has residual temperature, the residual temperature of the aluminum slag can be used to heat the falling aluminum raw material particles to reduce the temperature difference between the aluminum material and the molten aluminum liquid and improve the utilization efficiency of the residual heat. Compared with the prior art, the present invention adopts a closed smelting method, which can reduce heat loss and realize the automatic removal of aluminum slag from the aluminum liquid.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
