Specific embodiment
Figure 1A is the partial component schematic diagram of the spiral expanding machine of one embodiment of the invention.Please refer to Figure 1A, this implementation
The spiral expanding machine 100 of example includes main body 110 and an at least dilating screw 120.Main body 110 has high-pressure area R1, expansion
Region R2 and area of low pressure R3.Dilating screw 120 is configured at expansion area R2 and has inlet end 120a and exhaust end 120b, into
Gas end 120a connection high-pressure area R1, exhaust end 120b connection area of low pressure R3.The high pressure gas inputted from inlet end 120a drives
Dynamic dilating screw 120 rotates, and makes dilating screw 120 that can carry out the work such as power generation.Figure 1A only shows single dilating screw
120, so invention is not limited thereto, can be the form of twin-screw.
Fig. 2 shows that the adjustment part of Figure 1A is mobile.The spiral expanding machine 100 of the present embodiment includes further including adjustment part 130.
Adjustment part 130 covers at least partial lateral of dilating screw 120, and is suitable for moving along moving direction D relative to dilating screw 120
Between state shown in the state shown in Figure 1A and Fig. 2 and change the opening area of inlet end 120a, is existed with adjusting dilating screw 120
The pressure of exhaust end 120b gas be discharged makes dilating screw 120 in the pressure and low-pressure area of exhaust end 120b gas be discharged
The pressure of domain R3 is consistent, to reduce the power consumption of spiral expanding machine 100.In the present embodiment, the movement of adjustment part 130
Direction D is for example parallel to the pivot center A of dilating screw 120.
Specifically, adjustment part 130 more has recess 130a adjacent to the end of high-pressure area R1.When adjustment part 130
When being moved to first position shown in figure 1A, recess 130a is to the opening face for increasing inlet end 120a positioned at inlet end 120a
Product, at this time into dilating screw 120 gas pressure decline so that from exhaust end 120b be discharged gas pressure correspondingly under
Drop.Conversely, when adjustment part 130 is moved to the second position shown in Fig. 2, recess 130a dislocation in inlet end 120a with reduce into
The opening area of gas end 120a rises into the gas pressure of dilating screw 120 at this time, so that the gas being discharged from exhaust end 120b
Body pressure correspondingly rises.
The partial component block diagram for the spiral expanding machine that Fig. 3 is.Please refer to Figure 1A and Fig. 3, the present embodiment it is spiral
Expanding machine 100 further includes control module 140, and control module 140 is suitable for feeling respectively by its sensing unit 142 and sensing unit 144
The pressure of the pressure of the expansion area R2 of main body 110 and the area of low pressure R3 of main body 110 is surveyed, control unit 146 is according to carrying out self-induction
It surveys the sensing signal of unit 142 and sensing unit 144 and the movement of adjustment part 130 is controlled by driving unit 150 accordingly, make to expand
Screw rod 120 is consistent with the pressure of area of low pressure R3 in the pressure of exhaust end 120b gas be discharged.Sensing unit 142 and sensing are single
Member 144 is, for example, the pressure sensing element of appropriate type, and driving unit 150 is, for example, the actuator of appropriate type, and the present invention is not
This is limited.
Figure 1B is partial component schematic diagram of the spiral expanding machine in another section of Figure 1A.In detail, in the present embodiment
In, there is main body 110 perforation 110a, perforation 110a to be connected to expansion area R2, the sensing unit of control module 140 as shown in Figure 1B
142 sense the pressure of expansion area R2 by perforation 110a.Also that is, when recess 130a is in inlet end 120a, perforation 110a
It is arranged in main body 110.Furthermore, dilating screw 120 has multiple threaded sections, the first screw thread in these threaded sections
Section S1 abuts exhaust end 120b, and the second threaded sections S2 in these threaded sections abuts the first threaded sections S1 and do not abut
Exhaust end 120b, the perforation 110a of main body 110 are connected to the second threaded sections S2, certainly to sense in expansion area R2 not yet
And the pressure of the gas of exhaust end 120b will be reached.Under the configuration mode, the perforation 110a and expanding screw of main body 110
The exhaust end 120b of bar 120 along the distance of moving direction D be, for example, less than main body 110 perforation 110a and dilating screw 120 into
Gas end 120a is along the distance of moving direction D, and so invention is not limited thereto.In addition, the adjustment part 130 of the present embodiment is along the side of movement
Dilating screw 120 is greater than along the length of direction D to the length of D, and effectively to cover dilating screw 120, so the present invention is not also
This is limited.It should be noted that Figure 1A and Figure 1B are to keep attached drawing more clear with the office of cross-sectional representation display main body 110
Portion, actually main body 110 and adjustment part 130 collectively cover dilating screw 120 and only expose dilating screw 120 in inlet end 120a
And the regional area of exhaust end 120b, for air inlet and exhaust.
Fig. 4 is the main body of Figure 1A and the partial schematic diagram of adjustment part.Referring to FIG. 4, the adjustment part 130 of the present embodiment has
Guide groove 130c, main body 110 (being shown in Figure 1A) have guiding protrusion 112, and adjustment part 130 is by guide groove 130c along moving direction
D is slidedly arranged on guiding protrusion 112, and adjustment part 130 is enable smoothly to move along moving direction D.In other embodiments, can pass through
Other appropriate configurations set to be adjusted the cunning of part 130, and the present invention limits not to this.
Fig. 5 is the partial component schematic diagram of the spiral expanding machine of another embodiment of the present invention.Fig. 6 shows the adjustment of Fig. 5
Part is mobile.Fig. 5 and embodiment illustrated in fig. 6 and Figure 1A, Figure 1B and embodiment illustrated in fig. 2 are different in, adjustment part 130 '
Recess 130a ' is positioned at adjustment part 130 ' more adjacent to the end of area of low pressure R3.When adjustment part 130 ' is moved to shown in Fig. 3
First position when, recess 130a ' is to being located at exhaust end 120a to increase the opening area of exhaust end 120a, so that from exhaust end
The gas pressure decline of 120b discharge.Conversely, recess 130a ' is wrong when adjustment part 130 is moved to the second position shown in Fig. 4
The opening area of exhaust end 120a is reduced positioned at exhaust end 120a, so that the gas pressure being discharged from exhaust end 120b rises.
In addition, in Fig. 5 and embodiment illustrated in fig. 6, perforation 130b is formed in adjustment part 130 ' rather than embodiment is passed through as shown in Figure 1B
Hole 110a is formed in main body 110.Also that is, when recess 130a ' is in exhaust end 120b, perforation 130b is arranged in adjustment part 130 '.
Remaining of perforation 130b configures the configuration and the mode of action of the perforation 110a of Figure 1B similar with the mode of action, repeats no more in this.
In conclusion adjustment part can change it relative to dilating screw movement in spiral expanding machine of the invention
Coverage rate or its coverage rate to the exhaust end of dilating screw to the inlet end of dilating screw, to change the opening of inlet end
The opening area of area or exhaust end.It, can by the change of the opening area of the change or exhaust end of the opening area of inlet end
Dilating screw is adjusted in the pressure of exhaust end gas be discharged, makes dilating screw in the pressure and low pressure of exhaust end gas be discharged
The pressure in region is consistent, to reduce the power consumption of spiral expanding machine.
Although the present invention is disclosed as above with embodiment, however, it is not to limit the invention, any technical field
Middle technical staff, without departing from the spirit and scope of the present invention, when can make a little change and retouching, therefore protection of the invention
Subject to range ought be defined depending on appended claims.
