[0014] Beneficial effects

[0015] The utility model provides an aluminum rod gradient heating device. Compared with the existing technology, it has the following advantages:

[0016] (1) When the aluminum rod gradient heating device needs to heat the aluminum rod, the aluminum rod is first placed on the placement roller, and then the four electric push rods are turned on. The four electric push rods drive the mounting shell and the conveying roller close to the aluminum rod until the conveying roller contacts the surface of the aluminum rod and applies a certain pressure. At this time, the four second motors are turned on. The four second motors drive the multiple conveying rollers to rotate through the sprocket chain group. The multiple conveying rollers can then drive the aluminum rod to move when rotating. At this time, the electric heating tube is turned on. The electric heating tube generates heat to heat the aluminum rod below. At the same time, in order to ensure that the aluminum rod can be heated evenly, the first motor can be turned on. The first motor drives the gear to rotate. The gear drives the outer gear ring to rotate when rotating. The outer gear ring drives the rotating drum to rotate during the rotation process. The rotating drum can drive the aluminum rod to rotate during the rotation process, so that the aluminum rod can rotate during the transportation process.

In this way, the surface temperature of the aluminum rod can be more uniform, thereby improving the uniformity of heating to a certain extent and improving the heating effect of the aluminum rod.

[0017] (2) In the aluminum rod gradient heating equipment, part of the high-temperature harmful gas generated during the heating process of the aluminum rod will pass through three connecting pipes and enter the two thermal insulation interlayers. The waste heat of the high-temperature harmful gas is used to insulate the outer wall of the heating furnace, reducing the heat loss of the heating furnace itself, thereby reducing the energy consumption of the heating furnace and improving energy utilization efficiency. After the high-temperature harmful gas passes through the thermal insulation interlayer, it enters the filter purification box. The filter purification box is equipped with a filter purification device that can absorb and treat the harmful gas and then discharge it into the outside air, thereby reducing the impact of the harmful gas on the environment.

[0028] The gas processing assembly 8 includes two thermal insulation interlayers 82 , and both thermal insulation interlayers 82 are fixedly connected to the heating furnace 1 .

[0029] A group of conveying rollers 57 are rotatably installed on the inner wall of the mounting shell 56, and one end of the outer wall of a group of conveying rollers 57 passes through one side of the outer wall of the mounting shell 56. A sprocket chain group 58 is provided at one end of the outer wall of a group of conveying rollers 57. One end of the outer wall of a group of conveying rollers 57 is connected through the sprocket chain group 58. The sprocket chain group 58 is a prior art and is mainly composed of a chain and a sprocket for transmitting power. The sprocket chain group 58 can drive a group of conveying rollers 57 to rotate simultaneously. A second L-shaped plate 59 is fixedly installed on the outer wall of the mounting shell 56, and a second motor 510 is fixedly installed on one side of the outer wall of the second L-shaped plate 59. The output end of the second motor 510 passes through the outer wall of the second L-shaped plate 59 and extends to the other side and is fixedly connected to one end of the outer wall of one of the conveying rollers 57. When the four second motors 510 are turned on, the rotation direction of the four second motors 510 is set so that multiple groups of conveying rollers 57 can convey aluminum bars.

The first motor 53 can drive the outer ring gear 511 to rotate through the gear 54.

[0031] Figure 1-Figure 5 A second embodiment is shown, which differs from the first embodiment mainly in that:

[0032] The top of the heating furnace 1 is fixedly connected with three connecting pipes 81, and the three connecting pipes 81 are fixedly connected with the two thermal insulation interlayers 82 respectively. The connecting pipes 81 can introduce part of the high-temperature harmful gas inside the heating furnace 1 into the thermal insulation interlayer 82, and use the waste heat of the high-temperature harmful gas to insulate the outer wall of the heating furnace 1, thereby reducing the heat loss of the heating furnace 1 itself.

The inner walls of the three grooves are each provided with rolling balls 4. The placement rollers 3 can support the aluminum rods. The balls 4 are set to roll. The balls 4 are in contact with the aluminum rods, which can reduce the friction force on the aluminum rods during transportation and rotation.

[0034] A mounting frame 6 is fixedly mounted on the top of the inner wall of the heating furnace 1 , and a group of electric heating tubes 7 are fixedly mounted on the inner wall of the mounting frame 6 . The electric heating tubes 7 are conventional and can generate heat to heat the aluminum rods.

[0035] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0036] During operation, when the aluminum rod needs to be heated, the aluminum rod is first passed through the circular groove 2 on one side and placed on the placement roller 3. The aluminum rod will contact the ball 4 on the surface of the placement roller 3, and then the four electric push rods 55 are turned on. The four electric push rods 55 drive the installation shell 56 and the conveying roller 57 to approach the aluminum rod until the conveying roller 57 contacts the surface of the aluminum rod and applies a certain pressure. At this time, the four second motors 510 are turned on. The four second motors 510 drive the multiple conveying rollers 57 to rotate through the sprocket chain group 58. The multiple conveying rollers 57 can drive the aluminum rod to move when rotating. At this time, the electric heating tube 7 is turned on and the electric The heating tube 7 generates heat to heat the aluminum rod below. At the same time, in order to ensure that the aluminum rod is heated evenly, the first motor 53 can be turned on. The first motor 53 drives the gear 54 to rotate. The gear 54 drives the outer ring gear 511 to rotate during rotation. The outer ring gear 511 drives the rotating cylinder 51 to rotate during rotation. The rotating cylinder 51 can drive the aluminum rod to rotate during rotation, so that the aluminum rod can rotate during transportation. The rotation of the aluminum rod can make each side of the aluminum rod face the heating source in turn, avoiding the situation where some surfaces of the aluminum rod are heated for a long time while other surfaces are not heated enough when the aluminum rod is fixed. This can make the surface temperature of the aluminum rod more uniform, thereby improving the uniformity of heating to a certain extent and improving the heating effect of the aluminum rod. During the heating process of the aluminum rod, some of the high-temperature harmful gases generated will pass through the three connecting pipes 81 and enter the two thermal insulation interlayers 82. The waste heat of the high-temperature harmful gases is used to insulate the outer wall of the heating furnace 1, reducing the heat loss of the heating furnace 1 itself, thereby reducing the energy consumption of the heating furnace 1 and improving energy utilization efficiency. After the high-temperature harmful gases pass through the thermal insulation interlayer 82, they enter the filter purification box 83. The filter purification box 83 is provided with a filter purification device, which can absorb and treat the harmful gases and then discharge them into the outside air, thereby reducing the impact of the harmful gases on the environment.
