Abstract
The utility model relates to a press-in type energy saving fan. An air gathering device, a main air cylinder and an air transmission device are fixedly connected in sequence. The preceding stage vane wheel boss and the back stage vane wheel boss in the main air cylinder form frustum shapes and form an integral stream line body shape with the air gathering device stream line body of the inner part of the air gathering device. Branch ribs, stiffening ribs and steel reinforcement form a protective net. The design of the utility model is reasonable, the integral structure of the inner part of the fan forms a shuttle shape to make the internal resistance of the fan descend into the minimum, and the performance is stable. Compared with the original JBT type axial flow fan, the utility model can save electricity from 25 percents to 35 percents.
Description
The utility model relates to a kind of blower fan, exactly is a kind of forced energy-saving fan.
At present, the down-hole ventilation equipment blower fan that use in the mine mostly is axial fan greatly, and model mainly contains the JBT type, and this model blower fan internal drag is big, the power consumption height; The blast that existing draw-out type energy-saving fan produces when working is low.
It is a kind of rational in infrastructure simple that goal of the invention of the present utility model is to provide, stable performance, and can economize on electricity reaches the forced energy-saving fan of 25-35%.
The technical solution of the utility model is achieved in that forced energy-saving fan structure comprises wind collecting unit, main wind tube, air-delivery machine, and they are fixedly connected sequentially; Structure in the main wind tube is the left end that preceding grade blade wheel hub is installed in motor, back grade blade wheel hub is installed in the right-hand member of motor, the prime blade installation is on preceding grade blade wheel hub, back grade blade is installed on the grade blade wheel hub of back, the profile of preceding grade blade wheel hub and back grade blade wheel hub is taper type, and the small end of preceding grade blade wheel hub left, and the small end of back grade blade wheel hub to the right; The structure of wind collecting unit comprises housing and its inner wind collecting unit fairing, props up muscle, stiffening rib, reinforcing bar, the wind collecting unit fairing is the streamline bodily form, middle part in housing, small end are fixed with a muscle, stiffening rib left on its left part cylindrical, the other end that props up muscle, stiffening rib is fixed on the internal diameter of housing left end, propping up the muscle cross section is water droplet shape, and is hollow, and a muscle and stiffening rib are alternately, it is circular that they top equidistantly porose, reinforcing bar pass a corresponding hole of muscle and stiffening rib position; Have at least 3 guiding pieces that the middle part of air-delivery machine is fixed and be supported on to the air-delivery machine fairing in the air-delivery machine, the air-delivery machine fairing is the streamline bodily form, and small end to the right.
The utility model is reasonable in design, and blower fan inner body structure is fusiformis, and it is minimum that the blower fan internal resistance is dropped to, stable performance, and can economize on electricity with the comparison of former JBT profile shaft streaming blower fan reaches 25-35%.
Accompanying drawing 1 is the structure diagram of forced energy-saving fan;
1 wind collecting unit, 2 main wind tubes, 3 air-delivery machines, 4 preceding grade blades, 5 preceding grade blade wheel hubs, 6 back grade blade wheel hubs, 7 back grade blades, 8 guiding pieces, 9 air-delivery machine fairings, 10 motor, 11 holes;
Fig. 2 is the structure side view of forced energy-saving fan;
12 housings, 13 wind collecting unit fairings, 14 muscle, 15 stiffening ribs, 16 reinforcing bars.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1,2, the structure of forced energy-saving fan is: wind collecting unit 1, main wind tube 2, air-delivery machine 3 are fixedly connected sequentially; Structure in the main wind tube 2 is the left end that preceding grade blade wheel hub 5 is installed in motor 10, back grade blade wheel hub 6 is installed in the right-hand member of motor 10, preceding grade blade 4 is installed on the preceding grade blade wheel hub 5, back grade blade 7 is installed on the back grade blade wheel hub 6, the profile of preceding grade blade wheel hub 5 and back grade blade wheel hub 6 is taper type, and the small end of preceding grade blade wheel hub 5 left, and the small end of back grade blade wheel hub 6 to the right; The structure of wind collecting unit 1 comprises housing 12 and its inner wind collecting unit fairing 13, props up muscle 14, stiffening rib 15, reinforcing bar 16, wind collecting unit fairing 13 is the streamline bodily form, middle part in housing 12, small end left, be fixed with a muscle 14, stiffening rib 15 on its left part cylindrical, the other end that props up muscle 14, stiffening rib 15 is fixed on the internal diameter of housing 12 left ends, propping up muscle 14 cross sections is water droplet shape, and be hollow, prop up muscle 14 and stiffening rib 15 alternately, it is circular that they top equidistant porose 11, reinforcing bar 16 pass the corresponding hole in a muscle 14 and stiffening rib 15 positions 11; Have at least three guiding pieces 8 that air-delivery machine fairing 9 is fixing and be supported on middle part in the air-delivery machine 3 in the air-delivery machine 3, air-delivery machine fairing 9 is the streamline bodily form, and small end to the right.This structure makes wind collecting unit fairing 13 and preceding grade blade wheel hub 5 integral body become the streamline bodily form, makes air-delivery machine fairing 9 and back grade blade wheel hub 6 integral body become the streamline bodily form, and makes blower fan inner body structure be fusiformis.
