Description

Turbine exhausting blower is set up and is ventilated and agitating device

The utility model relates to a kind of improvement technology of Turbine exhausting blower, is that a kind of Turbine exhausting blower is set up ventilation and agitating device.

The rotating shaft of traditional Turbine exhausting blower can be along with fan blade rotates, only can be as the usefulness of factory or factory building air discharging and radiating, there is no other additional value, because Turbine exhausting blower mainly is to utilize air circulation convection current within doors and extraneous natural wind to blow, itself does not need to use power supply, save the energy and the function that regulates the room temperature so have, if but additional fan of Turbine exhausting blower or stirring vane promptly can be can be used to as ventilating and the purposes that stirs.

The purpose of this utility model is to propose a kind of Turbine exhausting blower and sets up ventilation and agitating device, this device is to extend a sheathed axle sleeve below the rotating shaft of Turbine exhausting blower, and in a terminal sheathed fan of axle sleeve or a paddle, as the usefulness of assisting air draft and stirring the material of lighter weight such as flour, feed, plastics, to increase the function of Turbine exhausting blower.

The technical solution of the utility model is to extend a sheathed axle sleeve below the rotating shaft of Turbine exhausting blower, and in a terminal sheathed fan of axle sleeve or a stirring vane, when wind-force outside the room drives the fan blade of revolving wormgear exhaust blower, fan or stirring vane can rotate along with the rotation of Turbine exhausting blower, discharge and as purposes such as the lighter flour of mixing quality, feed, plastics so as to hot-air that will be within doors.

The technical characterictic that Turbine exhausting blower of the present utility model is set up ventilation and agitating device is that this Turbine exhausting blower is the spherical that is made of most curved arc shape fan blades, and in the framework and the fixed mount center installing bearing block of Turbine exhausting blower, so as to setting up a rotating shaft, can rotate this bearing when making turbine air draft wind-engaging, and at the terminal rotary bar that extends a suitable length of rotating shaft, moving blade at the terminal sheathed fixedly plural number of rotary bar, sheathed locking one fan on the external screw thread of this rotating shaft lower end wherein, this fan will rotate with the fan blade of Turbine exhausting blower.According to the size of Turbine exhausting blower, can be between the rotating shaft of large-scale row's turbofan and fan sheathed locking one axle sleeve.According to the thickness degree of fan blade, can on thin blade, make the reinforcement groove of curved arc angle.

Remarkable advantage of the present utility model is Turbine exhausting blower additional can be ventilated or stirring vane, promptly can be used to as the usefulness than light material such as auxiliary air draft or stirring flour, feed, plastics.Save the energy more and improve use value.

Further specify structure content of the present utility model and feature below in conjunction with drawings and Examples.

Fig. 1 is the section combination schematic diagram that the utility model is installed draught fan.

Fig. 2 is the section combination schematic diagram that the utility model is installed stirring vane.

Figure number explanation: 10 Turbine exhausting blowers, 11 fan blades, 12 cover caps, 13 frameworks, 14 rotating shafts, 15 fixed mounts, 16 axle sleeves, 121 grooves, 122 hexagonal (hexagon)nuts, 123 packing rings, 124 axle beds, 131 support bodys 132,151 top chocks 133,152 steps 134,153 bearings, 135 fixed heads 141,142 external screw threads, 161 internal thread holes, 162 screws, 17 fans, 171 axostylus axostyles, 172 reinforcement grooves, 18 rotary bars, 19 stirring vane P screws

A kind of Turbine exhausting blower is set up fan assembly, as shown in Figure 1, its primary structure is, this Turbine exhausting blower 10 is by most curved arc shape fan blades 11, cover cap 12, framework 13, rotating shaft 14, fixed mount 15 elements such as grade combine, wherein, most fan blades 11 make the windward side that becomes to be the curved arc shape, and in regular turn most fan blade 11 rivetings knot is fixed in cover cap 12 and framework 13 around, so as to constituting the spherical of a hollow, and be arranged with a groove 121 at the center of cover cap 12 inside, from these groove 121 belows hexagonal (hexagon)nut 122 is set in regular turn, packing ring 123, axle bed 124, so as to wearing locking one rotating shaft 14, in addition in rotating shaft 14, lower end car system external screw thread 141,142, make this external screw thread 141 just can pass axle bed 124, utilize hexagonal (hexagon)nut 122 lock knots fixing again, utilize rivet that bearing 124 rivetings knot is fixed in the groove 121 of cover cap 12 at last, the external screw thread 142 of rotating shaft 14 lower ends passes the fixed head 135 in the middle of the framework 13, the riveting knot is fixed three stake bodies 131 on fixed head 135, but allow three stake bodies 131 just riveting knot be fixed in the circumference place of framework 13, in addition on fixed mount 15 tops, difference riveting knot is fixed in the middle of the bottom, step 132,133,151,152, simultaneously respectively last, step 132,133,151,152 inside hold in the installing, following two bearings 134,153, allow the external screw thread 142 of rotating shaft 14 lower ends run through and stretch out.When cross-ventilation or extraneous wind blows within doors, most curved arc shape fan blades 11 promptly forms a kind of state that rotates naturally, when Turbine exhausting blower 10 is installed, fixed mount 15 is arranged at suitable ventilation simultaneously, the external screw thread 142 lock knots that it is characterized in that these rotating shaft 14 lower ends are fixed in the internal thread 161 of axle sleeve 16 upper ends, and radially locate to establish a screw 162 in axle sleeve 16 lower ends, tie a fan 17 or a rotary bar 18 by the sheathed lock of screw P, be provided with an axostylus axostyle 171 and be sheathed on axle sleeve 16 lower ends in this fan upper end, and lock by screw P, fan 17 blades are provided with radian and reinforcement groove 172, and this fan 17 can be rotated along with the fan blade 11 of Turbine exhausting blower 10; As shown in Figure 2, at the terminal rotary bars 18 that extend suitable lengths of rotating shaft 14, and at the stirring vane 19 of rotary bar 18 terminal sheathed fixedly plural numbers.
