Detailed Description
Example one
See fig. 1-4.
A dust collection fan cover comprises a branch air pipe 1, a first pulley 6 and a first fan cover main body 10. The branch air pipe 1 is a square pipe. Wherein the top surface of the branch air duct 1 is substantially horizontal. The number of the first pulleys 6 is at least 1, and the first pulleys move along the top surface of the branch air pipe 1. The first wind shield body 10 comprises a handle 9, a first left plate 21, a first right plate 23, a first top plate 25 and a rear plate 27; the rear edge of the first left plate 21 is connected to the left side edge of the rear plate 27, the rear edge of the first right plate 23 is connected to the right side edge of the rear plate 27, the front end of the first top plate 25 has a semicircular first opening 19, the rear edge of the first top plate 25 is connected to the top edge of the rear plate 27, and the upper edge of the first left plate 21 and the upper edge of the first right plate 23 are connected to the left and right side edges of the first top plate 25, respectively. The rear plate 27 has a rear hole 29 in the middle. One end of the branch air duct 1 passes through the rear hole 29 and extends into the first fan housing main body 10, and the other end is connected to the main air duct 3. The first pulleys 6 are fixed to the outer side of the rear plate 27. Each first pulley 6 rolls along the outer wall of the branch duct 1. The handle 9 may be fixed to at least one of the first left and right plates 21, 23 and the first top plate 25.
Preferably, the handle 9 is fixed at both sides of the first opening 19 of the first top plate 25.
Preferably, there are 2 first pulleys 6, each of which runs along the top surface of the branch duct 1.
In use, the first hood body 10 is placed on the furnace cover 15 of the electrolytic furnace. The dust collection fan cover is positioned at the rear side of the center of the electrolytic furnace. The cathode 13 of the electrolytic furnace extends into the hearth of the electrolytic furnace from the first opening 19 of the first top plate 25. Harmful gas generated when the electrolytic furnace is used for producing rare earth metal or alloy through electrolysis, a small amount of rare earth compound flowing along with airflow and air near the electrolytic furnace are combined into waste gas, and the waste gas is sent to a subsequent treatment process from a dust collection air hood under the action of an induced draft fan.
When the anode 14 needs to be replaced, the first fan housing main body 10 is pulled upwards to push towards the main air duct 3; after the anode 14 is replaced, the handle is pulled to reset the first fan housing body 10. Since most of the weight of the first fan housing body 10 is shared by the first pulley 6, the friction between the branch duct 1 and the rear hole 29 is small, and the first fan housing body 10 can be easily moved.
Example two
