Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting auxiliary devices, and particularly relates to a device for improving the discharging uniformity of gas in a recycled aluminum furnace. Background Technique

[0002] When recycling and smelting waste aluminum materials, it is necessary to supply gas to the combustion chamber to ensure the temperature in the furnace. The current conventional method is that an operator holds a long rod-shaped spray gun, and after the spray gun is sent into the combustion chamber, the gas is sent by an external pump for combustion. In order to ensure relatively uniform combustion states at various places in the combustion chamber, the operator also needs to walk back and forth in front of the furnace door with the spray gun. This operation method obviously has great inconvenience, and at the same time, it cannot effectively ensure the uniform discharging of gas at various positions in the combustion chamber, which is the main problem to be solved at present. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to provide a device for improving the discharging uniformity of gas in a recycled aluminum furnace, so as to solve the problem that the gas discharging is not uniform enough when supplying gas to the combustion chamber of the recycled aluminum furnace, and it is impossible to ensure that the temperature changes at each point in the combustion chamber are consistent.

[0004] To solve the above problems, the utility model provides the following technical solutions:

[0006] Preferably, both end sides of the transverse air pipe are sealed; one end of the longitudinally arranged air pipe is connected to the middle of the transverse air pipe, and the vertical air pipes are evenly and equidistantly distributed on the transverse air pipe.

[0007] Preferably, it further includes a T-shaped rod; the T-shaped rod is placed horizontally; the longitudinally arranged air pipe is placed on the upper part of the longitudinal rod corresponding to the T-shaped rod; a clamping rotary rod is rotatably installed on the longitudinal rod of the T-shaped rod; the longitudinally arranged air pipe is detachably installed on the clamping rotary rod, and the longitudinally arranged air pipe can rotate relative to the T-shaped rod along with the clamping rotary rod; the support rod is fixed to the lower part of the transverse rod corresponding to the T-shaped rod.

[0008] Further, a gasket is also horizontally arranged on the lower bottom side of the support rod.

[0009] Further, the gasket is a planar structure in the shape of a rhombus, and one diagonal of the gasket is arranged along the depth direction of the heating chamber of the recycled aluminum furnace.

[0011] Further, the grip includes a protective sleeve fixed to the end of the T-shaped rod, and a chuck is also provided on the protective sleeve. The longitudinal air pipe is detachably connected to the T-shaped rod through the chuck.

[0012] Advantages of the utility model:

[0013] The utility model improves the extension rod of the traditional gas spray gun. Through the mutual combination of the longitudinal air pipe, the transverse air pipe and the vertical air pipe, gas can enter the combustion chamber of the recycled aluminum furnace relatively evenly along the air pipe, achieving a good air supply effect and making the temperature change more uniform everywhere in the combustion chamber. For this reason, the utility model also provides a corresponding support structure to make the overall device move more reliably and stably in the recycled aluminum furnace.

[0016] The following further introduces the utility model in combination with the drawings and specific embodiments:

[0017] Embodiment:

[0018] Referring to Figure 1 , this embodiment provides a device for improving the discharging uniformity of gas in a recycled aluminum furnace. It includes a longitudinally hollow longitudinal air pipe 1. A grip 2 and a transverse air pipe 3 are respectively arranged on the front and rear sides of the longitudinal air pipe 1, and a connector for connecting an external gas pipeline is installed at the end of the longitudinal air pipe 1 where the grip 2 is provided. A plurality of vertical air pipes 4 and a plurality of support rods 5 are respectively arranged on the upper and lower sides of the transverse air pipe 3. The longitudinal air pipe 1, the transverse air pipe 3 and the vertical air pipe 4 are connected and communicated. The length of the longitudinal air pipe 1 is greater than the depth of the heating chamber of the recycled aluminum furnace, and the length of the transverse air pipe 3 is less than the width of the heating chamber of the recycled aluminum furnace.

[0019] Both end sides of the transverse air pipe 3 are sealed. One end of the longitudinal air pipe 1 is connected to the middle of the transverse air pipe 3, and the vertical air pipes 4 are uniformly and equidistantly distributed on the transverse air pipe 3.

[0020] It further includes a T-shaped rod 7; the T-shaped rod 7 is placed horizontally; the longitudinal gas pipe 1 is placed on the upper part of the longitudinal rod of the T-shaped rod 7; a clamping rotating rod 8 is rotatably installed on the longitudinal rod of the T-shaped rod 7; the longitudinal gas pipe 1 is detachably installed on the clamping rotating rod 8, and the longitudinal gas pipe 1 can rotate relative to the T-shaped rod 7 along with the clamping rotating rod 8; the support rod 5 is fixed to the lower part of the cross rod of the T-shaped rod 7. In this embodiment, the lower end of the clamping rotating rod is installed at the middle position of the T-shaped rod through a universal hinge joint.

[0021] A gasket 6 is also horizontally arranged on the lower bottom side of the support rod 5.

[0022] The gasket 6 is a rhombic planar structure, and one diagonal of the gasket 6 is arranged along the depth direction of the heating chamber of the recycled aluminum furnace.

[0023] The support rods 5 are uniformly and equidistantly arranged on the cross rod of the T-shaped rod 7.

[0024] The grip 2 includes a protective sleeve fixed to the tail end of the T-shaped rod 7, and a chuck 9 is also arranged on the protective sleeve. The height of the chuck 9 is consistent with the height of the clamping rotating rod 8; the longitudinal gas pipe 1 is detachably connected to the T-shaped rod 7 through the chuck 9. Anti-slip patterns are also arranged on the outer surface of the grip 2. Arranging the anti-slip patterns can increase the friction force, thereby reducing the probability of dropping.

[0025] When using the utility model device in this embodiment, the operator only needs to connect the tail of the longitudinal gas pipe to the T-shaped rod through the grip, and then connect the adapter on the longitudinal gas pipe to the gas pipeline and then lift the T-shaped rod and send it into the recycled aluminum furnace together. After the gas is introduced into the combustion chamber, the operator only needs to move along the front-back direction of the furnace door to supply the gas to the front and back sides of the combustion chamber. In addition, the operator can also disconnect the longitudinal gas pipe from the grip and adjust the relative position of the vertical gas pipe in the combustion chamber by rotating the longitudinal gas pipe left and right; further improving the uniformity of gas discharge.
