Description

Technical Field

[0001] This utility model relates to the field of metal smelting equipment technology, and in particular to an automated smelting furnace. Background Technology

[0002] In the fields of metal smelting, casting, and materials processing, smelting furnaces are one of the core pieces of equipment, used to heat metals or alloys to a molten state for casting, refining, or composition adjustment. During operation, smelting furnaces require stirring of the raw materials inside. For example, Chinese utility model patent CN202421589393.X discloses a stirring device for a casting aluminum alloy smelting furnace. The drive motor 2 on its sealed cover drives the transmission rod 4 to rotate via a transmission box 201, thereby rotating the inclined stirring rod 401 and the horizontal stirring rod 402 to stir the molten aluminum. However, this stirring mechanism only allows the stirring rods to stir the molten material in a fixed position during operation, resulting in poor stirring efficiency and affecting the uniformity of heating and the smelting effect.

A feeding channel connected to the upper part of the furnace body's circumferential wall is fixedly arranged therein, and a discharge channel connected to the interior is fixedly arranged near the lower part of the furnace body's circumferential wall. An electric heating system is installed inside the furnace body. A furnace cover is fixedly arranged on the upper part of the furnace body. A first motor is fixedly arranged in the middle of the upper part of the furnace cover. The drive shaft of the first motor is connected to an active shaft rotatably arranged below the furnace cover. A stirring sleeve shaft, capable of rotating synchronously with the active shaft, is slidably fitted at the lower end of the active shaft. An inner connecting plate is fixedly fitted on the upper end of the outer circumferential wall of the stirring sleeve shaft.

A drive mechanism for driving the reciprocating lifting and lowering motion of the outer connecting plate is provided on the upper part of the furnace cover. Multiple sets of stirring blades are uniformly spaced and fixedly arranged on the outer circumferential wall of the stirring sleeve shaft below the outer connecting plate.

[0006] Furthermore, the discharge channel is equipped with a matching on / off valve.

[0007] Furthermore, a heat insulation sleeve is fixedly fitted on the outer peripheral wall of the furnace body.

[0008] Furthermore, the inner wall of the furnace body is provided with an inner ring groove, and the electric heating system includes a spiral heater coiled inside the inner ring groove and a controller located outside the furnace body and electrically connected to the spiral heater.

[0009] Furthermore, the outer peripheral wall of the drive shaft is uniformly provided with a plurality of elongated connecting bosses along the circumferential direction, and the inner peripheral wall of the stirring sleeve shaft is provided with a plurality of connecting grooves that are adapted to each of the connecting bosses.

[0010] Furthermore, two vertical guide rods are symmetrically fixed at both ends of the upper part of the outer connecting plate, and the two guide rods are respectively slidably sealed with the through holes opened on the furnace cover.

[0011] Furthermore, the driving mechanism includes a vertically fixed mounting plate on the upper part of the furnace cover.

The left and right ends of the connector slide in cooperation with the limiting ring grooves on the eccentric wheel and the limiting plate, respectively.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention uses a first motor to drive the drive shaft, stirring sleeve shaft, and multiple sets of stirring blades on the stirring shaft to rotate synchronously to stir the molten material inside the furnace. Meanwhile, a second motor drives an eccentric wheel to rotate. During the rotation of the eccentric wheel and the limiting plate, the connecting ring groove and the connecting head limit sliding cooperation cause the corresponding guide rod to drive the connecting outer plate, connecting inner plate, stirring sleeve shaft, and multiple sets of stirring blades to make linear reciprocating motion in the vertical direction. This allows the multiple sets of stirring blades to change their stirring position in the vertical direction while rotating and stirring the molten material, thereby effectively improving the stirring efficiency and ensuring uniform heating and smelting effect of the molten material.

The electric heating system includes a spiral heater 7 coiled inside the inner ring groove 6 and a controller 8 located outside the furnace body 1 and electrically connected to the spiral heater 7. During operation, the controller 8 realizes automatic control of the heating temperature and heating time of the spiral heater 7.

[0023] A heat insulation sleeve 9 is fixedly fitted on the outer peripheral wall of the furnace body 1 to improve the heat insulation performance of the smelting furnace during operation.

[0024] A furnace cover 10 adapted to the furnace body 1 is fixedly installed on the upper part. A first motor 11 is fixedly installed in the middle of the upper part of the furnace cover 10. The drive shaft of the first motor 11 is connected to an active shaft 12 rotatably installed below the furnace cover 10. A stirring sleeve shaft 13 capable of rotating synchronously with the active shaft 12 is slidably fitted at the lower end of the active shaft 12. Figure 2As shown, the outer peripheral wall of the drive shaft 12 is uniformly provided with a plurality of elongated connecting protrusions 14 along the circumferential direction, and the inner peripheral wall of the stirring sleeve shaft 13 is provided with a plurality of connecting grooves 15 that are adapted to each of the connecting protrusions 14.

[0025] An inner connecting plate 16 is fixedly sleeved on the upper end of the outer peripheral wall of the stirring sleeve shaft 13. An outer connecting plate 17 is sleeved on the outside of the inner connecting plate 16, and the inner connecting plate 16 is rotatably engaged with the connecting ring groove 18 opened on the inner peripheral wall of the outer connecting plate 17.

[0026] The upper part of the furnace cover 10 is provided with a drive mechanism for driving the reciprocating lifting and lowering motion of the outer connecting plate 17; multiple sets of stirring blades 19 are fixedly installed at even intervals on the outer peripheral wall of the stirring sleeve shaft 13 below the outer connecting plate 17.

[0027] Two vertical guide rods 20 are symmetrically fixed at both ends of the upper part of the external connecting plate 17, and the two guide rods 20 are respectively slidably sealed with the through holes opened on the furnace cover 10.

[0028] In this embodiment, the driving mechanism includes a vertically fixed mounting plate 21 on the upper part of the furnace cover 10. A second motor 22 is fixedly mounted on one side of the mounting plate 21, and the drive shaft of the second motor 22 is connected to an eccentric wheel 23 located on the other side of the mounting plate 21.
