Abstract
The utility model belongs to the field of a recovery system fan used for spinning production lines in the spandex fiber industry, and provides a leak-proof recovery system fan special for spandex. The leak-proof recovery system fan special for the spandex is mainly composed of a shell, a fan inlet, a fan outlet, an impeller, a rotating shaft, a belt, a motor, a bearing seat, a labyrinth device and a hub. The fan is driven by the motor through the belt, the bearing seat supports the rotating shaft to drive the impeller on the hub to rotate, and the hub inside the shell is sealed through the labyrinth device. The leak-proof recovery system fan special for the spandex is characterized in that an auxiliary impeller is additionally arranged on the impeller. The leak-proof recovery system fan special for the spandex has the advantages of being novel in structure, low in manufacturing cost, easy to seal and free of leakage.
Description
Technical field:
The utility model is for the reclaiming system blower fan field of spandex fibre industry spinning production line.
Background technique:
Shown in Fig. 1,2, existing elastic spandex fiber reclaiming system blower fan, this reclaiming system blower fan mainly is comprised of housing 1, blower fan import 2, fan outlet 3, impeller 4, running shaft 5, belt 6, motor 7, bearing support 8, filler device 9, wheel hub 10.This blower fan is by motor 7, by belt 6 transmissions, the running shaft 5 that High Rotation Speed is supported by bearing support 8, rotary blade 4, make 2 one-tenth negative pressure of blower fan import, suck the air that contains inflammable and explosive irritative gas, by impeller 4 rotary compressions, by fan outlet 3, carried, its Blower Housing 1 is inner and outside to be sealed by filler device.The defect of above-mentioned reclaiming system blower fan comprises:
, housing 1 inside and outside is by filler device 9 packing seals, its sealing, be subject to running shaft 5 circular runout Accuracies, causes that inflammable and explosive irritative gas is leaked to outside in housing 1 inside, sealing effect is poor;
, housing 1 inside and outside is by filler device 9 packing seals, its sealing, affected by the elastic qualities of filler own, causes that inflammable and explosive irritative gas is leaked to outside in housing 1 inside, sealing effect is poor;
, housing 1 inside is by filler device 9 packing seals, its sealing, affected by the pressure size at high-speed rotating impeller wheel hub 10 places, causes that inflammable and explosive irritative gas is leaked to outside in housing 1 inside, sealing effect is poor;
, housing 1 inside is by filler device 9 packing seals, its sealing, affected by filler device 9 gland tightness, gland is crossed mandrel and is easily generated heat, is out of shape, and crosses pine and easily causes that explosive irritative gas is leaked to outside in housing 1 inside, sealing effect is poor;
, explosive irritative gas leaks, and enters workshop, degradation manipulation environment, improve the environment explosion ratio, strengthen hidden peril of explosion;
Summary of the invention:
The purpose of this utility model is in order to address the aforementioned drawbacks, the reclaiming system blower fan of the special-purpose anti-leak of a kind of spandex of ad hoc meter, this apparatus structure novelty, overcome above-mentioned existing poor, the explosive irritative gas of sealing effect caused because of factors such as running shaft circular runout precision, filler rebound elasticity, wheel hub stream pressure, gland tightness and easily entered workshop, worsen the shortcomings such as production environment, raising explosion ratio, enhancing hidden peril of explosion, therefore the reclaiming system blower fan of the special-purpose anti-leak of a kind of spandex is provided.
Solution of the present utility model is:
The reclaiming system blower fan of the special-purpose anti-leak of a kind of spandex, mainly be comprised of housing, blower fan import, fan outlet, impeller, running shaft, belt, motor, bearing support, maze device, wheel hub; It is characterized in that: increase by a sub-propeller on impeller.
This blower fan is by motor, and by belt transmission, High Rotation Speed is by the running shaft of bearing support support, and rotary blade, make the blower fan import become negative pressure, sucks the air that contains inflammable and explosive irritative gas, by impeller, compresses, and by fan outlet, carried.Its blower fan is inner and outside by the labyrinth system sealing, when the rotary blade High Rotation Speed, and secondary stress high-speed synchronous rotation on impeller, make between wheel hub and labyrinth seal to produce micro-negative pressure, guarantee the inner inflammable and explosive irritative gas of blower fan, under micro-suction function, can't leak to outside.
Simultaneously, adopt contactless labyrinth seal, overcome the running shaft circular runout, sealing is easily leaked, and the easy phenomenons such as heat, distortion of Gland tension, running shaft.
The beneficial effects of the utility model are, this apparatus structure novelty; Low cost of manufacture; Easily sealing is without leaking.
The accompanying drawing explanation:
Fig. 1 is the schematic diagram of the reclaiming system blower fan of existing elastic spandex fiber;
Fig. 2 is the side view of the reclaiming system blower fan of existing elastic spandex fiber;
The schematic diagram that Fig. 3 is the special-purpose anti-leak reclaiming system of a kind of spandex of the present utility model draught fan impeller;
The schematic diagram that Fig. 4 is the special-purpose anti-leak reclaiming system of a kind of spandex of the present utility model draught fan impeller;
The schematic diagram that Fig. 5 is the special-purpose anti-leak reclaiming system of a kind of spandex of the present utility model blower fan.
Embodiment:
As shown in Figure 3,4, the special-purpose anti-leak reclaiming system of a kind of spandex draught fan impeller mainly is comprised of impeller 4, wheel hub 10, sub-propeller 11, and its sub-propeller 11 is to set up at existing draught fan impeller 4 back side deciles, after setting up, adopts dynamic balancing measurement, guarantees overall precision.
As shown in Figure 4,5, the reclaiming system blower fan of the special-purpose anti-leak of a kind of spandex, mainly be comprised of housing 1, blower fan import 2, fan outlet 3, impeller 4, running shaft 5, belt 6, motor 7, bearing support 8, maze device 9, wheel hub 10, sub-propeller 11.This blower fan is by motor 7, and by belt 6 transmissions, High Rotation Speed is by the running shaft 5 of bearing support 8 supports, and rotary blade 4, make 2 one-tenth negative pressure of blower fan import, and the air that suction port contains explosive irritative gas, by impeller 4 compressions, is carried by fan outlet 3.Its blower fan is inner and outside by the labyrinth system sealing, when rotary blade 4 High Rotation Speed, sub-propeller 11 high-speed synchronous rotations on impeller, make 9 of wheel hub 10 and maze devices produce micro-negative pressure, guarantee the inner explosive irritative gas of blower fan, under micro-suction function, can't leak to outside, finally form the reclaiming system blower fan apparatus of the special-purpose anti-leak of a kind of spandex.
