The mounting plates 3 are equipped with noise reduction components and mounting components.

[0023] Example 1: The noise reduction component includes two mounting plates 3 with a first galvanized iron sheet 4 on opposite sides. Sound-absorbing cotton 5 is provided on the opposite side of the first galvanized iron sheet 4, and a second galvanized iron sheet 6 is provided on the outside of the sound-absorbing cotton 5.

[0024] The sound-absorbing cotton 5 is sandwiched between the first galvanized iron sheet 4 and the second galvanized iron sheet 6. The sound-absorbing cotton 5 reduces noise when the cooling fan is running.

[0025] Both mounting plates 3 have bolts 7 threadedly connected to their outer sides. Both mounting plates 3 have first threaded holes on their outer sides. The first galvanized iron sheet 4, the sound-absorbing cotton 5, and the second galvanized iron sheet 6 all have through holes. The bolts 7 are threadedly connected to the mounting plates 3 through the through holes and the first threaded holes.

[0026] The thickness of the first galvanized sheet metal 4 and the second galvanized sheet metal 6 is one millimeter, the thickness of the sound-absorbing cotton 5 is two centimeters, and the number of bolts 7 is several, used to fix and install the straight cylindrical first galvanized sheet metal 4 and the second galvanized sheet metal 6.

[0027] It should be noted that the noise reduction device for the cooling fan of the electric furnace induction body is equipped with noise reduction components connected to the air outlet 2 of the cooling fan. This reduces the noise emitted by the cooling fan, facilitates communication and assessment of equipment operation by staff in various positions, reduces the physical and mental harm to staff, and ultimately improves the effectiveness of the cooling fan.

[0028] Specifically, in use, the noise reduction device for the cooling fan of the electric furnace induction body involves clamping and installing the noise-reducing cotton 5 between the first galvanized iron sheet 4 and the second galvanized iron sheet 6. Then, the first galvanized iron sheet 4 and the second galvanized iron sheet 6, which are made into straight cylinders, are fixed to the outside of the mounting plate 3 with bolts 7. Subsequently, the two mounting plates 3 are fixed and limited between the air outlet pipe 1 and the air outlet 2 of the cooling fan, and the connection is sealed with a sealing ring 13. This device can reduce noise during the operation of the cooling fan, facilitate communication and assessment of equipment operation by staff at various positions, reduce the physical and mental harm to staff, and thus improve the effectiveness of the cooling fan.

[0029] Example 2: Please refer to Figure 1 Based on Embodiment 1, an installation component is also provided on the mounting plate 3. The installation component includes an L-shaped mounting bracket 8 that is movably installed on the opposite side of the two mounting plates 3.

A fixing block 11 is fixedly installed on the opposite side of the two mounting plates 3. Screws 12 are threadedly connected to the opposite side of the two sets of fixing blocks 11.

[0030] Both the mounting plate 3 and the L-shaped mounting bracket 8 have connecting holes inside. The two sets of fixing blocks 11 have second threaded holes on opposite sides. The screws 12 are threadedly connected to the fixing blocks 11 through the connecting holes and the second threaded holes, which facilitates the fixed installation of the first limiting frame 9 and the second limiting frame 10, and also facilitates the disassembly and recycling of the first limiting frame 9 and the second limiting frame 10.

[0031] The mounting components also include sealing rings 13 installed on the outside of the air outlet 1 and the air outlet 2 of the cooling fan. The interior of both mounting plates 3 is provided with slots, and the sealing rings 13 fit into the slots to reduce the leakage of air from the connection.

[0032] A screw 14 passes through the first limiting frame 9 and the second limiting frame 10. Both the first limiting frame 9 and the second limiting frame 10 have extension holes. The screw 14 passes through the extension holes and passes through the interior of the first limiting frame 9 and the second limiting frame 10 in sequence. A nut 15 is threaded onto the outside of the screw 14, which stably limits the first limiting frame 9 and the second limiting frame 10 to the outside of the air outlet 1 or the air outlet 2 of the cooling fan.

[0033] It should be noted that the noise reduction device for the cooling fan of the electric furnace induction body is equipped with an installation component, which makes it easy to fix the noise reduction device between the air outlet duct 1 and the air outlet 2 of the cooling fan, thereby improving the noise reduction effect of the cooling fan and facilitating subsequent maintenance operations.

[0034] Specifically, the noise reduction device for the cooling fan of the electric furnace induction body fixes two sets of L-shaped mounting brackets 8 to one side of the mounting plate 3 with screws 12, so that the first limiting frame 9 and the second limiting frame 10 fit against the outside of the air outlet 1 and the air outlet 2 of the cooling fan. The screw 14 passes through the first limiting frame 9 and the second limiting frame 10 in sequence and is installed and fixed with nuts 15, so that the first limiting frame 9 and the second limiting frame 10 are limited to the outside of the air outlet 1 and the air outlet 2 of the cooling fan, thereby fixing the noise reduction component between the air outlet 1 and the air outlet 2 of the cooling fan.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) When using the silencing device for the cooling fan of the electric furnace induction body, the silencing cotton 5 is clamped and installed between the first galvanized iron sheet 4 and the second galvanized iron sheet 6.

Then, the two mounting plates 3 are fixed and limited between the air outlet pipe 1 and the air outlet 2 of the cooling fan. The connection is sealed by the sealing ring 13. The device can perform noise reduction treatment when the cooling fan is running, which facilitates information communication and judgment of equipment operation status by staff in various positions, reduces the physical and mental damage to staff, and improves the effect of the cooling fan.

[0037] (2) The noise reduction device for the cooling fan of the electric furnace induction body fixes two sets of L-shaped mounting brackets 8 to one side of the mounting plate 3 with screws 12, so that the first limiting frame 9 and the second limiting frame 10 fit against the outside of the air outlet pipe 1 and the air outlet 2 of the cooling fan. The screw 14 passes through the first limiting frame 9 and the second limiting frame 10 in sequence and is installed and fixed with nuts 15, so that the first limiting frame 9 and the second limiting frame 10 are limited to the outside of the air outlet pipe 1 and the air outlet 2 of the cooling fan, thereby fixing the noise reduction component between the air outlet pipe 1 and the air outlet 2 of the cooling fan.
