Abstract
The utility model discloses a supercharged air cannon device, which comprises an air cannon, and an injection pipe connected with an air outlet of the air cannon; the inner wall of the injection pipe is provided with a supercharged nozzle jet; the inner diameter of the middle of the supercharged nozzle jet is smaller than that of the end part of the supercharged nozzle jet; and the outer diameter of the two ends of the supercharged nozzle jet is equal to the inner diameter of the nozzle jet. The supercharged nozzle jet is arranged on the inner wall of the injection pipe, and the inner diameter of the middle of the supercharged nozzle jet is smaller than that of the end part of the supercharged nozzle jet; and according to a Laval effect, the pressure of airflow is increased after the airflow passes through the supercharged nozzle jet, the spray-explosion pressure of the air cannon can be improved, the blockage clearing effect of the air cannon is improved, and the supercharged air cannon device is simple in structure, economic and practical.
Description
Technical field
The utility model belongs to the air bubble technical field, relates in particular to a kind of boosting type air bubble device.
Background technology
Air bubble (having another name called air broken arch flow-aid device or Cleaning device for pipeline) is to lean on the strong air flow of ejection pressure gas suddenly; Directly pour the inaccessible faulty section of storing bulk material with the speed that surpasses one Mach (velocity of sound); The expansion shock wave of this unexpected release; Overcome the material static friction, made the material in the container recover again to flow.It is to utilize aerodynamic principle, by a differential pressure device with can realize that automatically controlled quick exhaust valve moment can be transformed into the jet kinetic force with compressed-air actuated pressure, produce strong wallop; It is the desirable block clearing slag-blowing equipmemt of a kind of cleaning, pollution-free, low power consuming.Air bubble jet pipe inwall is generally the cylinder plane, and the air communication that air bubble produces is crossed jet pipe and is injected in the feed bin, and pressure is big inadequately sometimes, causes the block clearing weak effect.
The utility model content
The purpose of the utility model provides the boosting type air bubble device of a kind of pressure height, good blocking cleaning effect.
For achieving the above object, the technical scheme that the utility model adopts is:
Boosting type air bubble device comprises air bubble and the jet pipe that links to each other with the air bubble air extractor duct, and the jet pipe inwall is provided with the supercharging jet pipe, and the internal diameter at said supercharging jet pipe middle part is less than the internal diameter of supercharging nozzle-end, and supercharging jet pipe two ends external diameter equals the jet pipe internal diameter.
Said supercharging jet pipe middle part internal diameter is 1/2～9/10 of a jet pipe internal diameter.
In the utility model; At the jet pipe inwall supercharging jet pipe is set, the internal diameter at supercharging jet pipe middle part is less than the internal diameter of supercharging nozzle-end, according to the Lavalle effect; Air communication is crossed supercharging jet pipe downstream pressure and will be increased; Can improve air bubble spray detonation pressure power, improve the air cannon block-removing effect, simple in structure, economical and practical.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1; Boosting type air bubble device comprises air bubble 1 and the jet pipe 4 that links to each other with the air extractor duct 2 of air bubble 1, and jet pipe 4 is fixed on the bin wall 5; Jet pipe 4 inwalls are provided with supercharging jet pipe 3; The internal diameter at said supercharging jet pipe 3 middle parts is less than the internal diameter of supercharging jet pipe 3 ends, and supercharging jet pipe 3 two ends external diameters equal the internal diameter of jet pipe 4, and said supercharging jet pipe 3 middle part internal diameters are 1/2～9/10 of jet pipe 4 internal diameters; Supercharging jet pipe 3 can improve air bubble spray detonation pressure power effectively, improves the air cannon block-removing effect.
