[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] like Figure 1 As shown, the present application provides a bottom-mounted electromagnetic pushing double-chamber furnace, including a double-chamber furnace mechanism 1, which is arranged in an aluminum smelting processing plant and is used to melt raw materials through high-temperature molten aluminum. The double-chamber furnace mechanism 1 includes a first furnace body 2, wherein the first furnace body 2 is arranged on the ground, and a second furnace body 3 is arranged on one side of the first furnace body 2. The first furnace body 2 and the second furnace body 3 are independent of each other and are both used for smelting aluminum raw materials. The first furnace body 2 and the second furnace body 3 are both made of steel structure.

[0026] A lifting platform 7 is disposed on the top of the first furnace body 2 and the second furnace body 3. A furnace door 71 is disposed on one side of the lifting platform 7. The furnace door 71 may be an electric or hydraulic furnace door in this embodiment. A fume hood 73 is also disposed on the furnace door 71. The fume hood 73 is used to collect the fume emitted from the furnace when the furnace door 71 is opened.

[0027] At the same time, a maintenance platform 72 is provided at the bottom of the lifting platform 7, and the maintenance platform 72 is provided at the top of the first furnace body 2 and the second furnace body 3, so as to facilitate the staff to perform maintenance and repair work on the first furnace body 2 and the second furnace body 3.

[0028] like Figure 2-Figure 3As shown, a main chamber 21 is provided inside the first furnace body 2, and the main chamber 21 is a charging chamber for adding and melting raw materials. Meanwhile, a secondary chamber 31 is provided inside the second furnace body 3, and the secondary chamber 31 is a high-temperature aluminum liquid chamber for heating aluminum liquid. The temperature of the secondary chamber 31 is higher than that of the main chamber 21, and the inner walls of the main chamber 21 and the secondary chamber 31 are lined with refractory materials.

[0029] At the same time, a regenerative burner 6 is provided on one side of the main chamber 21 and the auxiliary chamber 31. The regenerative burner 6 in the auxiliary chamber 31 is used to heat the aluminum liquid in the auxiliary chamber 31. At the same time, the regenerative burner 6 inside the main chamber 21 is used to treat aluminum slag, and when the regenerative burner 6 in the auxiliary chamber 31 is repaired, the aluminum liquid with insufficient temperature is heated.

[0030] Two groups of flow channels 4 are provided between the main chamber 21 and the auxiliary chamber 31. One end of the flow channel 4 is connected to the main chamber 21, and the other end is connected to the auxiliary chamber 31. The flow channel 4 is used to connect the main chamber 21 with the auxiliary chamber 31, so that high-temperature aluminum liquid flows in the main chamber 21 and the auxiliary chamber 31, thereby making the flue gas in the main chamber 21 and the auxiliary chamber 31 intercommunicate, achieving the effect of balancing the furnace pressure in the first furnace body 2 and the second furnace body 3;

[0031] At the same time, an electromagnetic pusher 5 is arranged at the bottom (underground) of the first furnace body 2 and the second furnace body 3. The bottom-mounted electromagnetic pusher 5 can drive the aluminum liquid to circulate in the main chamber 21 and the auxiliary chamber 31 through the magnetic lines of force in the air. The electromagnetic pusher 5 itself does not come into contact with the aluminum liquid, and the flow rate of the aluminum liquid driven by the electromagnetic pusher 5 through the electromagnetic force is greater than that of the mechanical pump and the pipeline pump, so that the circulation effect of the aluminum liquid is better;

[0032] The electromagnetic pusher 5 has no wearing parts and can operate stably and uninterruptedly for a long time. The device itself has low power consumption, and the cost of use is also reduced.

[0033] like Figure 4-Figure 6 As shown, when the furnace door 71 is opened, most of the smoke emitted from the furnace will be discharged through the smoke hood 73, while a small part of the smoke will adhere to the inside of the smoke hood 73 and solidify. In order to prevent the accumulation of attachments, improvements are made to the smoke hood 73, specifically:

[0034] An inclined guide plate 731 is provided on one side of the fume hood 73, a connecting groove 732 is provided at the bottom of the guide plate 731, and a heating assembly 8 is provided on the outside of the guide plate 731. The heating assembly 8 includes a plurality of heat pipes 81 fixedly installed on the outside of the guide plate 731, a heating medium flows inside the heat pipes 81, and the temperature of the heating medium is higher than the melting temperature of the attached matter, and an electric box 82 is fixedly installed on the other side of the fume hood 73, a heating pump is provided inside the electric box 82, and the heating pump is connected with the heat pipe 81 to introduce the heating medium into the heat pipe 81;

[0035] At the same time, a collecting vehicle 74 is arranged at the bottom of the guide plate 731, and a guide block 741 is arranged at the top of the collecting vehicle 74. The size of the guide block 741 matches the size of the connecting groove 732. The collecting vehicle 74 is installed at the bottom of the guide plate 731 through the cooperation of the guide block 741 and the connecting groove 732. At this time, the bottom end of the guide plate 731 is connected with the inside of the collecting vehicle 74.

[0036] When the furnace door 71 is opened, the attachments formed after the smoke is cooled adhere to the inner side of the smoke hood 73. At this time, the heat pipe 81 is driven by the control electric box 82 to continuously heat the guide plate 731, so that the attachments attached to the inside of the guide plate 731 melt and flow along the guide plate 731 to the collection vehicle 74, thereby improving the cleanliness of the smoke hood 73 and reducing maintenance costs.

[0037] In summary, the device is provided with a first furnace body 2 and a second furnace body 3, and the two are connected in series through a flow channel 4, and an electromagnetic pusher 5 is provided at the bottom to drive the aluminum liquid to flow and form a circulation, which not only makes the circulation effect of the aluminum liquid better, but also when one group of regenerative burners 6 needs maintenance, another group of regenerative burners 6 can be opened for heating, thereby increasing the life of the device and reducing the difficulty of maintenance.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
