Abstract
The utility model discloses an improved air suction tube of a draught fan. A flexible extension tube is sleeved on a tube body at one end of the air suction tube connected with an air suction opening of the draught fan. The utility model has a simple structure, can effectively eliminate the connection and the vibration of the air suction tube and the draught fan, and guarantees the normal operation of the draught fan.
Description
Technical field
The utility model relates to a kind of improved induced draught fan suction pipe.
Background technique
To be connected with suction pipe be to adopt direct hard connecting mode to induced draught fan in the coal powder injection dust pelletizing system, because the pipeline temperature drop is big in producing, the amount of expanding with heat and contract with cold is big, and the expanding with heat and contract with cold of airduct produces huge pulling force and will affact Blower Housing.And blower fan is in operation and produces slight vibration, and the bolt of pipeline and blower fan is often cut off in pulling force and vibration, very easily causes the blower fan damage, the repairing of being forced to stop production.
The model utility content
The purpose of this utility model is to provide a kind of improved induced draught fan suction pipe, and it is simple in structure, is easy to manufacture, and can eliminate vibration and stress between induced draught fan and the suction pipe effectively, guarantees that blower fan normally uses.
The purpose of this utility model is achieved in that a kind of improved induced draught fan suction pipe, and suit is being provided with flexible telescopic tube on the suction pipe one end body that links to each other with the air sucking mouth of induced draught fan.
Induced draught fan is linked to each other by flexible telescopic tube with suction pipe, change original direct hard connecting mode into the mode that is flexible coupling easily, like this, the pulling force that produces that expands with heat and contract with cold of airduct no longer directly affacts Blower Housing.And the slight vibration that the short tube on the fan casing produces with casing also can not be subjected to the constraint of suction pipe.Thereby can ensure the sealing of pipeline, eliminate the damage of casing bolt again, improve operation rate.The utility model is simple in structure, can eliminate the vibration that is connected between suction pipe and the induced draught fan effectively, guarantees the induced draught fan proper functioning.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main TV structure schematic representation of the utility model embodiment 1;
Fig. 2 is main TV structure schematic representation of the utility model embodiment 2.
Embodiment
A kind of improved induced draught fan suction pipe, as shown in Figure 1 and Figure 2, suit is being provided with flexible telescopic tube 2 on the suction pipe 3 one end bodys that link to each other in the air sucking mouth with induced draught fan 1.During connection, flexible telescopic tube 2, no longer directly is connected between the air sucking mouth of suction pipe 3 and induced draught fan 1 on suction pipe 3 so firmly by steel band 4 colligations, thereby can ensure the sealing of pipeline, the damage of having eliminated casing bolt Yin Lali and vibration again and having produced has improved operation rate.
Said flexible telescopic tube 2 is rubber pipe or bellows.
Claims (2)
1. improved induced draught fan suction pipe, it is characterized in that: suit is being provided with flexible telescopic tube on the suction pipe one end body that links to each other with the air sucking mouth of induced draught fan.
2. improved induced draught fan suction pipe according to claim 1 is characterized in that: said flexible telescopic tube is rubber pipe or bellows.
