Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Below with reference to the accompanying drawings it is described in detail a kind of pulse damper according to the present utility model.
As shown in Figure 1 to Figure 3, a kind of pulse damper according to the present utility model, including：Ontology 100, elastic membrane 200,
Feed pipe 310, discharge nozzle 320, gas nozzle 400.
Specifically, defining cavity in ontology 100.
Elastic membrane 200 is located in the cavity so that the cavity is divided into the first Room 110 and second Room 120.
Feed pipe 310 and discharge nozzle 320 are oppositely arranged and are connected to the first Room 110.
Gas nozzle 400 is connected to second Room 120.It is understood that gas nozzle 400 also with low pressure gas body tied to source.
A kind of pulse damper according to the present utility model, is connected with diaphragm pump.Specifically, feed pipe 310 connects diaphragm
The discharge end of pump, fluid foods or particulate dust by diaphragm pump extruding be pumped in the first Room 110, at this time material pressure with every
Membrane pump discharges, and end pressure is equal, and 310 end recurrent pulses pressure peak of feed pipe is typically about 0.7Mpa.Elastic membrane 200 is by object
Material pressure expands to the right (as shown in Figure 3), compresses the second Room 120 on right side, and right side second Room 120 passes through gas nozzle 400 and low pressure
Gas source is connected, and pressure is the half of pulse peak value after low-pressure gas voltage stabilizing, and material pushes 200 compression and low pressure of elastic membrane
Air work, to reduce material internal pressure.As 310 end material recurrent pulses pressure of feed pipe gradually reduces, material
When pressure is less than low-pressure gas pressure, low-pressure gas acting pushes elastic membrane 200 to move downward (as shown in Figure 2), improves material
Internal pressure, and pressing materials make it smoothly be flowed out from discharge nozzle 320.Until next period material pressure is more than low-pressure gas pressure
Power completes the voltage stabilizing of a cycle at this time.
In the above process, a kind of pulse damper according to the present utility model makes the periodicity of original 0~0.7MPa
Pulse is converted to the constant pressure of continuous 0.35MPa, to effectively avoid fluid foods the high pressure of bend pipe is washed away or
Airborne dust of the particulate dust in outlet.
Advantageously, the volume of the first Room 110 is more than the volume of second Room 120.
Advantageously, the cavity is configured to cylinder.Advantageously, the internal diameter phase of the internal diameter of feed pipe 310 and discharge nozzle 320
The internal diameter of the same and respectively less than described cavity.Advantageously, the internal diameter of gas nozzle 400 is less than the internal diameter of feed pipe 310.
Advantageously, elastic membrane 200 is made of polyurethane rubber.The variation of material intercycle property pulse makes elastic membrane
200 leftward or rightward motion compresses low-pressure gases actings, the pulse to reach material are converted to constant pressure.
A kind of pulse damper according to the present utility model realizes stable diaphragm pump discharging using the compressibility of gas
The material pressure at end makes the material pressure of diaphragm pump discharge end be substantially at constant.That is, when the pressure of diaphragm pump discharge end material
When tending to surge pressure, the impact of diaphragm pump discharge end material pressure can be effectively reduced, reduces the flow velocity of material, reduces material pair
The impact of elbow etc. simultaneously reduces airborne dust etc..When the pressure of diaphragm pump discharge end material tends to valley pressure, then can compensate every
Membrane pump discharge end material pressure, to stablize material pressure.
