[0013] Compared with the prior art, this utility model provides a refining furnace alloy feeding chute structure, which has the following beneficial effects:

[0014] The alloy feeding chute structure of this refining furnace features a baffle plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 A refining furnace alloy feeding chute structure includes: an alloy chute 1, a baffle plate 2 embedded on the outside of the alloy chute 1, an observation window 3 connected to the other side of the alloy chute 1, a bend 41 connected to the outside of the alloy chute 1, and a compressed air tank 4 connected to the outside of the bend 41, a compressed air valve 43 assembled on the outside of the compressed air tank 4, and a sealing plate 32 assembled inside the observation window 3.

[0021] Alloy chute 1 is a common chute structure in the prior art. Baffle plate 2 can prevent material from falling directly and causing impact damage to alloy chute 1. Observation window 3 makes it convenient for staff to observe the working status inside alloy chute 1. Compressed air tank 4 can clean the inside of alloy chute 1 through compressed air valve 43 to prevent alloy chute 1 from becoming blocked.

[0022] The alloy chute 1 is fitted with a protective sleeve 11, and a rubber pad is embedded in the outside of the protective sleeve 11. The protective sleeve 11 can prevent the alloy chute 1 from being damaged by external impact during use. The alloy chute 1 is fitted with a flange 12, and the flange 12 has openings evenly distributed on its outside. The flange 12 facilitates the connection and assembly of the alloy chute 1 with external workpieces.

[0023] The bottom of the compressed air tank 4 is equipped with foot pads 44. There are at least two sets of foot pads 44, and the bottom of the foot pads 44 is equipped with anti-slip pads. The foot pads 44 can support the compressed air tank 4. The outside of the bend 41 is equipped with a pressure gauge 42, which can display the pressure status inside the compressed air tank 4, making it convenient for the staff to control the compressed air tank 4.

[0024] The observation window 3 includes an observation port 31, which is connected to the alloy chute 1. A sealing sleeve 33 is connected between the observation port 31 and the alloy chute 1. The observation port 31 is connected to the sealing plate 32 by a hinge. An assembly frame 34 is fitted around the outside of the observation port 31. The observation port 31 can communicate with the alloy chute 1. The sealing sleeve 33 can improve the airtightness between the observation port 31 and the alloy chute 1. The assembly frame 34 facilitates the assembly of the observation port 31.

[0025] In this design, when the alloy chute 1 is in use, a baffle plate 2 is added to the bottom. When the workpiece is unloaded, it first collides with the baffle plate 2, which reduces the falling speed of the material and protects the alloy chute 1. At the same time, the added observation window 3 allows the staff to observe the working condition inside the alloy chute 1. The added compressed air tank 4, controlled by the compressed air valve 43, discharges the air inside the compressed air tank 4 into the interior of the alloy chute 1 to purge the alloy chute 1, which is prone to clogging, and achieves anti-clogging.
