Description
Technical field
The utility model relates to a kind of annealing furnace accessory, especially a kind of furnace bottom blower fan.
Background technique
Annealing furnace is a kind of novel thermal process heat transmission equipment, is mainly used in the annealing of large-scale carbon steel, alloyed steel part; Mode of heating has electric heating, fuel oil, combustion gas, fire coal, heated air circulation etc.The furnace bottom blower fan is positioned at the annealing furnace bottom and is used to provide circulating wind; The furnace bottom blower fan comprises circulation fan blade and circulation motor; Existing circulation fan blade comprises coupling disc and fan blade; Fan blade is arranged on the circumference of coupling disc, and four lack protective gear in fan blade, and the working life of under abominable heat treatment environment, working is shorter; Existing in addition furnace bottom blower fan transmission performance is longer, and motor shaft and coupling disc form rigid being in transmission connection, and the furnace bottom motor oscillating is bigger, therefore is necessary existing furnace bottom blower fan is improved.
Summary of the invention
The purpose of the utility model is a kind of long service life that designs for the deficiency that solves above-mentioned technology, the furnace bottom blower fan that fan blade is not fragile, transmission is effective, vibration is little.
The furnace bottom blower fan that the utility model designed, it mainly comprises circulation fan blade, motor and support, described circulation fan blade comprises coupling disc and fan blade; Said fan blade is arranged on the circumference of coupling disc; Said motor is connected on the support, it is characterized in that said motor is positioned at cradle, and the motor shaft of motor is provided with first belt pulley; Below, said support upper-end surface is provided with a gearbox; The gearbox lower end is input as second belt pulley, and its upper end output shaft and said coupling disc are in transmission connection, and said first belt pulley is connected through belt with second belt pulley; Said circulation fan blade also comprises last disk ring and lower wall that the edge raises up in, and fan blade is arranged between disk ring and the lower wall and is connected with them, and is separated out the air port that is circumferential arrangement in the side.
As preferably, said motor bottom surface is concordant with the support bottom surface, and like this, the vibration major part of motor can be absorbed by ground, further reduces vibration.
As preferably, said support divides two-layer up and down, and said gearbox is positioned at the upper strata, and such structure is more firm.
The furnace bottom blower fan of the utility model gained, last disk ring and lower wall can effectively protect fan blade, thereby make fan blade not fragile, prolong its working life; And go up disk ring and lower wall can be fixed fan blade, can improve the stress performance of fan blade in operation process; In addition, can lead to the wind in the operation process effectively in the air port, improves controllability; Moreover, through so soft being in transmission connection of belt, can effectively improve the transmission effect, increase the service life; Simultaneously, because said motor is positioned at cradle, the vibration major part of motor can be absorbed by ground, therefore vibrates less.

Embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Embodiment 1:
As shown in Figure 1, the described furnace bottom blower fan of present embodiment, it mainly comprises circulation fan blade 7, motor 8 and support 13; Described circulation fan blade 7 comprises coupling disc 1 and fan blade 2, and said fan blade 2 is arranged on the circumference of coupling disc 1, and said motor 8 is connected on the support 13; Said motor 8 is positioned at support 13 sides, and said motor 8 bottom surfaces are concordant with support 13 bottom surfaces, like this; The vibration major part of motor 8 can be absorbed by ground, further reduces vibration; 8 in the motor of motor 8 is provided with first belt pulley 10; Below, said support 13 upper-end surfaces is provided with a gearbox 9, and said support is two-layer about in the of 13 minutes, and said gearbox 9 is positioned at the upper strata; Such structure is more firm; Gearbox 9 lower ends are input as second belt pulley 11, and its upper end output shaft and said coupling disc 1 are in transmission connection, and said first belt pulley 10 is connected through belt 12 with second belt pulley 11; Like Fig. 2,3, shown in 4, said circulation fan blade 7 also comprises last disk ring 3 and lower wall 4 that edge 6 raises up in, and fan blade 2 is arranged between disk ring 3 and the lower wall 4 and is connected with them, and is separated out the air port 5 that is circumferential arrangement in the side.
The described furnace bottom blower fan of present embodiment, last disk ring 3 can effectively protect fan blade 2 with lower wall 4, thereby makes fan blade 2 not fragile, prolongs its working life; And go up disk ring 3 and can fix fan blade 2 with lower wall 4, can improve the stress performance of fan blade 2 in operation process; In addition, can lead to the wind in the operation process effectively in air port 5, improves controllability; Moreover, through so soft being in transmission connection of belt, can effectively improve the transmission effect, increase the service life; Simultaneously, because said motor 8 is positioned at support 13 sides, the vibration major part of motor 8 can be absorbed by ground, therefore vibrates less.
The protection domain that need to prove this patent is not limited to the foregoing description, and those of ordinary skills do conventional change according to above-mentioned teachings, should all fall into the protection domain of this patent.
