In the present invention, because two disks are arranged on the eccentric position of housing 2, Slidine-vane rotor 5 is arranged on the eccentric position of two disks, so just can make Slidine-vane rotor 5 change between the central position of housing 2 and the eccentric position of housing 2 by rotating two disks.Because the rodless cavity of the first cylinder in the first eccentricity control bar 6 is communicated with relief opening 13, in the second eccentricity control bar 7, the rodless cavity of the second cylinder is communicated with suction port 12, in the time that the gas in relief opening 13 and suction port 12 has pressure, will have thrust to disk.When suction port 12 pressure are during much larger than relief opening 13 pressure, the first eccentricity control bar 6 and spring push-rod 8 are less than the thrust of the second eccentricity control bar 7 to disk to the gross thrust of disk, disk is positioned in a position, and at this moment, Slidine-vane rotor 5 is positioned at the central position of housing 2.In the time that suction port 12 pressure and relief opening 13 pressure approach, the first eccentricity control bar 6 and spring push-rod 8 are greater than the thrust of the second eccentricity control bar 7 to disk to the gross thrust of disk, disk is positioned in another position after turning over several angle, and at this moment, Slidine-vane rotor 5 is positioned at the eccentric position of housing 2.
When the present invention works, suction port 12 connects pressurized gas by pipeline, and relief opening 13 connects empty container by pipeline.Its working procedure is divided into two stages: the first stage, be operated in impeller pattern; Second stage, is operated in slide vane compressor pattern.
When first stage, pressure P1 in the first eccentricity control bar 6 is less than the pressure P2 in the second eccentricity control bar 7, now the thrust of the first eccentricity control bar 6 is less than the thrust of the second eccentricity control bar 7, two disks are positioned in position 1 under the poor effect of the thrust of two bars, the now central position of Slidine-vane rotor 5 in housing 2, the slide plate 18 on Slidine-vane rotor 5 is now as impeller.
Pressurized gas by pipeline by suction port 12 tangentially to flow in the active chamber of housing 2, due to High Pressure Difference effect, flow to the air-flow high speed impact slide plate 18 of active chamber, promote Slidine-vane rotor 5 and rotate, the torque of Slidine-vane rotor 5 reaches flywheel 11 by gear train 15, and flywheel driven 11 rotates.After gas push slide plate 18, discharge from relief opening 13.Like this, gas is constantly entered by suction port 12, promote Slidine-vane rotor 5, discharged by relief opening 13, flywheel 11 rotating speeds constantly increase, until when between the suction port 12 of active chamber and relief opening 13, pressure reduction is reduced to certain value, air-flow no longer has impetus to slide plate 18, now the rotating speed of flywheel 11 reaches maximum, and gas pressure energy is converted into rotating mechanical energy to greatest extent.In this stage, the present invention has realized the conversion of gas pressure energy to flywheel rotating mechanical energy.This part rotating mechanical energy provides energy for second stage work.
Along with suction pressure constantly reduces, exhaust pressure constantly increases, poor the reducing of thrust of two eccentricity control bars, in the time that pressure reduction is reduced to certain value Δ P, under additional spring push-rod 8 effect, all turn an angle α stopping at 2 places, position of two disks, now, Slidine-vane rotor 5 is positioned at eccentric position in housing 2, and the gear train 15 between rotating shaft 14 and the flywheel 11 of Slidine-vane rotor 5 remains engagement, and the present invention starts the work of second stage.Now flywheel 11 provides driving force pressurized gas for Slidine-vane rotor 5, P2 reduces, and P1 increases, and the pressure reduction of two eccentricity control bars is by just bearing change and constantly increasing, the thrust of the first eccentricity control bar 6 is greater than the thrust of the second eccentricity control bar 7, so two disks are positioned in position 2.Realize Slidine-vane rotor 5 from center to eccentric automatic switchover, and not by outside energy.
Second stage, Slidine-vane rotor 5 is positioned at eccentric position, and that the active chamber part of housing 2 completes is air-breathing, compression, exhaust process, has realized the compression of gas.By the first stage to second stage, Slidine-vane rotor 5 remains rotation, when second stage starts, Slidine-vane rotor 5 is with the highest angular velocity rotation, the slide plate 18 being located thereon is under the effect of centrifugal force, get rid of to housing 2 inwalls, in active chamber, form 8 compression chambers, because Slidine-vane rotor 5 is positioned at eccentric position, along with the rotation of rotor, the volume of these compression chambers constantly changes, suction port 12 is positioned on the path of compression chamber volume increase, when compression chamber volume increases, internal gas pressure reduces, form negative pressure, air-breathing from suction port 12, complete air-breathing after, the volume of compression chamber increases to maximum and then reduces, relief opening 13 is positioned on the path that compression chamber volume reduces, in the time of compression chamber process relief opening 13, the gas pressure intensity of compression chamber inside is greater than relief opening 13 gas pressure intensities, so, gas is discharged through relief opening 13 by compression chamber.
In this process, gas pressure intensity increases, and has realized the compression of gas.Complete the required energy source of gas compression and be stored in the rotating mechanical energy in flywheel 11 in the first stage.Along with increasing of gas pressure intensity, the rotating speed of flywheel 11 reduces, and rotating mechanical energy is converted into the pressure energy of gas.Due to the consumption of energy in working procedure of the present invention, can not complete the compression of all gas,, in the time not completing the compression of all gas, rotating mechanical energy releases, Slidine-vane rotor 5 will stop operating, and therefore needing provides part energy to compressor in advance again.This part energy is provided by the elastic potential energy being added in advance in volute spring 9.Before compressor starts work, be that volute spring 9 adds elastic potential energy in advance by handwheel, because the pressure push-rod 23 in differential pressure control valve 10 is communicated with suction port 12, under High Pressure, the piston rod Compress Spring 19 of pressure push-rod 23 separates two gears in engaging and disengaging gear 16, makes locking device 24 by the central shaft clamping of volute spring 9 simultaneously.Along with the reduction of suction port 12 pressure, the thrust of pressure push-rod 23 reduces, under the effect of spring 19, make two Gear Contact engagements in engaging and disengaging gear 16, discharge locking device 24 simultaneously, elastic potential energy in volute spring 9 is discharged with the form of torque, for the invention provides driving force, complete follow-up compression process.In this process, the elastic potential energy of volute spring 9 is converted to rotating mechanical energy and is converted to gas pressure energy again.
When completing after the work in above two stages, an operation cycle of the present invention finishes.
Application of the present invention and using method are exemplified below:
One, for coal spraying process.In coal spraying process, two winding-up tanks are arranged in juxtaposition, when a winding-up tank coal powder injection, and another filling puffing coal and pressurising, winding-up tank spraying coal powder in turn.Pressurized gas is nitrogen, before coalingging, needs the nitrogen of emptying winding-up tank mesohigh, with after guaranteeing that coal dust can pack in winding-up tank smoothly, complete to coaling, then fills nitrogen in winding-up tank.In this process, a part of high pressure nitrogen enters in air and slatterns, and the present invention can collect this part nitrogen and be reused for breeze blowing process.
Three winding-up tanks, are respectively tank a, tank b and tank c, and tank a has been the winding-up tank that residual high pressure nitrogen is housed after winding-up process, and the relative pressure of its internal gas is P
1; Tank b is slack tank, and relative pressure is 0; Tank c is the winding-up tank of jetting, and coal dust and high pressure nitrogen are equipped with in inside.
Tank a is carried out to pressure release, prepare for coalingging.To between tank a and tank b, connect with the present invention by pipeline.Open the valve of tank a, high pressure nitrogen enters the active chamber of housing 2 through suction port 12 by pipeline, after promoting slide plate 18 actings, and pressure decreased, kinetic energy reduces, and discharges active chamber through relief opening 13, then enters tank b through pipeline.When the pressure reduction of suction port 12 and relief opening 13 is reduced to certain value Δ P
0time, two eccentricity control bars and spring push-rod 8 are controlled Slidine-vane rotor 5 and are switched to eccentric position by center.Now Slidine-vane rotor 5 is still keeping higher rotating speed under the drive of flywheel 11, and flywheel 11 discharges rotating mechanical energy, drives Slidine-vane rotor 5 to carry out gas compression.Along with the continuous reduction of tank a pressure, constantly the increasing of tank b pressure, the rotating speed of flywheel 11 reduces, and rotating mechanical energy is converted into the pressure energy of gas.When suction port 12 pressure decreaseds are to a certain extent time, discharge volute spring 9, for Slidine-vane rotor 5 provides driving force, so just can complete the compression of residual gas.
After tank a is emptying by the way, high pressure nitrogen wherein is not wasted, but has collected in tank b.Now can, to tank a filling coal dust, then fill nitrogen.For coal powder injection next time ready.

1, stand-by storage e is slack tank, its relative pressure is P
2.Between tank d and tank e, connect with the present invention by pipeline.When normal working, the first valve closing on the pipeline of connection the present invention and tank d, the second valve open on the pipeline of connection the present invention and tank e.The present invention is original state, and Slidine-vane rotor 5 is positioned at housing 2 central positions, and volute spring 9 is in impaction state.
Installation detecting device on work storage tank d is opened the first valve at once in the time that detection device detects that work storage tank d occurs to reveal, and starts the present invention, is communicated with work storage tank d and stand-by storage e.At this moment, the gas in tank d by the present invention to tank e pressure release.When pressure release, swiftly flowing air-flow drives Slidine-vane rotor 5 and flywheel 11 to rotate.Gas pressure energy is converted into the rotating mechanical energy of flywheel 11.When the pressure reduction of two tanks is reduced to setting value Δ P
0time, two eccentricity control bars and spring push-rod 8 are controlled two disks and are rotated, and make Slidine-vane rotor 5 switch to eccentric position by the central position of housing 2, and the present invention enters second stage, flywheel 11 discharges rotating mechanical energy, drives Slidine-vane rotor 5 to carry out gas compression.When the pressure decreased of suction port 12 is to a certain extent time, discharge volute spring 9, for Slidine-vane rotor 5 provides driving force, complete the compression of remaining gas.So far compressor operating finishes, and gas all enters tank e by tank d.
Being similar in these above-mentioned occasions, the gas that occurs to reveal may be flammable explosive gas, and like this, once reveal, electrical spark can not appear in scene, otherwise can cause an explosion accident, and therefore, in these occasions, is brownout.The energy source needing in Self-operated air compressor work of the present invention is in the pressure energy of gas and be added in advance the elastic potential energy in volute spring 9 in advance, does not need external driving can complete the transfer process of gas, therefore can use safely under these occasions.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.For example, the engaging and disengaging gear in the present invention and differential pressure control valve can be other structures, lock volute spring when large as long as can realize pressure at suction port, and the pressure decreased of suction port discharges volute spring to a certain extent time.
