Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy melting equipment, in particular to a well logging furnace body. Background Art

[0002] Aluminum and aluminum alloy melting furnaces are commonly used equipment in the aluminum processing and casting field. Their melting process is also the production link with the largest energy and material consumption in the aluminum processing industry. The structural design of the aluminum melting furnace is directly related to the energy utilization efficiency, safety, and service life.

[0003] In the prior art, the joints between the furnace top, furnace wall, and furnace door frame of the well logging furnace body are built with refractory bricks and refractory mud. After long-term use of the well logging furnace, gunfire phenomena are likely to occur at the joints between the furnace top, furnace wall, and furnace door frame of the well logging furnace body, cracks are generated at the joints between the furnace top, furnace wall, and furnace door frame of the furnace body, and the flue gas and flame inside the furnace body escape through the cracks; and when the furnace door is opened for feeding, a large amount of heat is dissipated, and the flue gas and flame will also overflow at the joint between the furnace top and the furnace door frame and rise up along the lintel, burning out the hydraulic pipelines and hydraulic cylinders of the furnace door lifting and pressing devices, causing damage to electrical instruments, electrical circuits, equipment pipelines, hydraulic cylinders, etc., affecting normal production; at the same time, since the thickness of the furnace door slope extending from the bottom of the furnace body to the furnace door platform gradually decreases, leakage of aluminum is likely to occur at the joint between the furnace door platform and the furnace door slope. When feeding materials, the aluminum materials often hit the joint between the furnace door slope and the furnace door platform. When skimming the slag, the rake head is likely to touch the joint between the furnace door slope and the furnace door platform. After long-term use, the refractory material at the joint between the furnace door slope and the furnace door platform falls off, cracks will be generated, and the high-temperature aluminum liquid will penetrate into the cracks and flow into the pits formed by the falling of the refractory material, and finally penetrate into the steel structure, resulting in the occurrence of aluminum leakage accidents. Summary of the Invention

[0004] The utility model provides a well logging furnace body to solve the problems that cracks are easily generated at the joints between the furnace top, furnace wall, and furnace door frame of the existing well logging furnace body, and leakage of aluminum is likely to occur at the joint between the furnace door platform and the furnace door slope. The well logging furnace body can effectively avoid the generation of cracks at the joints between the furnace top, furnace wall, and furnace door frame, thereby avoiding the upward escape of flue gas and flame from the furnace body; at the same time, it can effectively avoid the occurrence of aluminum leakage at the joint between the furnace door slope and the furnace door platform.

[0009] Furthermore, the flue is arranged in the middle of the rear end of the furnace body, and a lifting pump is arranged inside the lifting pump chamber. The lifting pump can discharge the molten aluminum in the measuring well furnace and transport the molten aluminum to the next process.

[0010] Furthermore, a plurality of reserved holes for installing burners are arranged on the top of the furnace top, and the number of the reserved holes is six.

[0011] Furthermore, the cross-sections of the first protrusion and the second protrusion are both trapezoidal structures. The first protrusion is embedded in the first groove, and the second protrusion is embedded in the second groove.

[0012] Furthermore, the included angle between the connection part of the furnace door slope and the furnace door platform is 139°.

[0013] Furthermore, the height of the upper surface of the lintel of the furnace door frame is lower than the height of the upper surface of the furnace top, aiming to reduce the flue gas and flame escaping from the furnace door.

In this embodiment, a furnace door is installed at the furnace door frame 10, and the furnace door is opened to add aluminum alloy waste into the furnace body to melt the aluminum alloy waste.

[0025] The furnace body includes a furnace top 3, a furnace wall 5, a furnace bottom 7 and a furnace door platform 9.

In this embodiment, the furnace wall 5 includes two side furnace walls and a rear furnace wall, wherein the tops of the two side furnace walls and the rear furnace wall are provided with a first protrusion 6, and the first protrusion 11 cooperates with the first groove so that the furnace wall 5 and the furnace top 3 are mutually displaced and filled in a concave-convex combination manner. At the same time, the joint of the furnace wall 5 and the furnace top 3 is compacted with castables to avoid the occurrence of gunfire at the joint of the furnace wall 5 and the furnace top 3. The second protrusion 11 cooperates with the second groove so that the furnace top 3 and the door lintel of the furnace door frame 10 are mutually displaced and filled in a concave-convex combination manner.

[0026] One end of the furnace bottom 7 is inclined upwardly to be provided with a furnace door slope 8, the furnace door slope 8 is connected to the furnace door platform 9, the furnace door slope 8 has a consistent thickness from bottom to top along the upward extension direction, and the angle between the furnace door slope 8 and the furnace door platform 9 is an obtuse angle.
