Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is porting partial structural diagram of the invention.
Specific embodiment
As depicted in figs. 1 and 2, a kind of frequency modulation compressed gas self-excited pulse generator is by shell 1, air inlet 3 and gas outlet 4
It is formed.The inner end top of shell is equipped with demarcation plate 14.Space is main gas circuit room 2 in the shell of demarcation plate upper end.It is located at
Space is energy storage tank 6 in the shell of demarcation plate lower end.Space body in the indoor spatial volume of main gas circuit and energy storage tank
Product is than being 1: 4~5.
Accumulation of energy diaphragm 7 is equipped in the lower part of energy storage tank, accumulation of energy diaphragm closes the lower space of energy storage tank.The accumulation of energy film
Piece is located in energy storage tank at bottom 1/5th at 1/6th.In the middle part of the lower end surface of the accumulation of energy diaphragm and inner end bottom surface of shell
Between be equipped with return tower spring 9.The accumulation of energy diaphragm is made of elastic wear-resisting synthetic material, so that it has enough flexible bullets
Property.
The gas outlet communicated with main gas circuit room is equipped in the middle part of the upper surface of shell.Upper surface a side of shell is equipped with and master
The air inlet that gas circuit room communicates.
A side of demarcation plate is longitudinally equipped with the porting 10 for penetrating through main gas circuit room and energy storage tank.Porting is by being located at
Porting adjusting knob 11 outside corresponding side body controls opening and closing.The porting adjusting knob connection is located at the spiral shell outside shell
18 outer end of bar, inner bolt hole lateral direction penetrating are corresponded to and are arranged in inner bolt hole outside side body with porting, screw rod, the opening and closing of screw rod inner end
Porting, on the outside of inner bolt hole with sealing ring 17 is equipped between corresponding screw rod, so as to be sealed between screw rod periphery and inner bolt hole.
Porting adjusting knob by the screw rod of energy transverse seal porting, can control the mistake tolerance or opening and closing intake and exhaust of porting
Mouthful.
The middle part of demarcation plate corresponding with gas outlet is equipped with longitudinally through hole 19.It is set on the demarcation plate of through hole lower end
There is the damping magnetic patch 13 with mider hole.The upper end of valve rod 15 is equipped with the valve block 5 of opening and closing gas outlet, and the upper surface of the valve block is set
There is rubber gasket 16, to guarantee the salable gas outlet of valve block.
The lower end of valve rod passes through through hole and the mider hole of damping magnetic patch is connect with the upper end of push-pull rod 8, under push-pull rod
It holds and is connect in the middle part of the upper surface with accumulation of energy diaphragm.The junction of the valve rod and push-pull rod is equipped with the fixation spiral shell of predetermined stroke amount
Bolt 12, for adjusting the overall length of push-pull rod and valve rod, to be suitble to valve block can be when return tower spring jacks up accumulation of energy diaphragm, push-and-pull
The overall length of bar and valve rod can make valve block seal gas outlet.
The damping magnetic patch is overlapped with perforation axially bored line.The valve rod periphery and through hole internal perisporium slide fit, i.e. shape
It is connect at sealing longitudinal axis.
The valve rod is iron valve rod, with the damping action generated by the magnetic field magnetic force for damping magnetic patch come control valve
Bar, it is ensured that the valve block for closing gas outlet has certain inertia, stop valve rod can at an arbitrary position during uplink and downlink, and
And it must be by can upper and lower displacement when external force.
The present invention is to enter main gas circuit room from air inlet using pressed gas, and closing in gas outlet increases pressure in shell
With make gas outlet open make shell pressure reduce during, the effect of the accumulation of energy diaphragm in energy storage tank is made using the variation of pressure
Power constantly changes, and control gas outlet, which is formed, to be automatically closed and automatic open-minded, generates the self-excited pulse effect of compressed gas.
In use, air inlet communicates compressor, gas outlet communicates the bottom of aeration oxidation pool.
Of the invention is open-minded: pressed gas enters main gas circuit room 2 from air inlet, that is, works as inlet charge, and gas outlet is in
When closed state, due to pressure principle, the intake air pressure of main gas circuit room will be gradually increased, and pass through porting to accumulation of energy
Tank pressurising.The accumulation of energy diaphragm of energy storage tank inner cavity larger area can be generated one and transported downwards, to low pressure by the effect of inflation pressure
Dynamic active force, when active force is greater than the elastic force of support top accumulation of energy diaphragm lower end return tower spring；Accumulation of energy diaphragm is by this active force
Effect, after running down a distance, by coupled push-pull rod with pulling down, also band ovable valve stem and valve block are in the same direction
Lower movement makes valve block with gas outlet mutually from gas outlet is open-minded, and intake air pressure leaks, and completes opening process of the invention.
Closing of the invention: pressed gas enters main gas circuit room from air inlet, when gas outlet is in open state, due to pressure
The intake air pressure of strong principle, main gas circuit room will be gradually reduced, and energy storage tank is to the pressure release of main gas circuit room；Accumulation of energy diaphragm loses simultaneously
Pressure, return tower spring lose pressure on top surface return, and return tower spring will push up out generation one to accumulation of energy diaphragm and move to gas outlet
Active force, accumulation of energy diaphragm brings up push-pull rod and moves upwards, and also band ovable valve stem and valve block move upwards, by this active force
Effect, after running a distance, until valve block contact gas outlet, complete closing gas outlet, system close, complete of the invention
Closing process.
In the case where accumulation of energy tank volume is fixed, the pore size that porting 10 is communicated with main gas circuit room decides accumulation of energy
The rate of tank internal pressure variation, also just decides the frequency of pulse, and the effect of porting adjusting knob is exactly adjustment aperture
Size, to adjust pulse frequency, general air pulsing generator is difficult to accomplish ultralow frequency, but frequency of the invention can accomplish it is minimum
0.1Hz~300Hz.
In short, the present invention can obtain the effect for being aerated with pulse on-off type and improving oxygen solution transfer rate, there is structure letter
Single, regulation is convenient, low manufacture cost and the good advantage of using effect.
