Description

Technical Field

[0001] The utility model relates to the technical field of gas generators, in particular to a pulse gas generator. Background Art

[0002] Currently, the main methods of material conveying include vehicle transport, scraper conveying, screw conveying, belt conveying, and gas conveying. Gas conveying can be divided into positive pressure conveying and negative pressure conveying. Positive pressure gas conveying is further divided into steady-state gas conveying and pulsed gas conveying. In steady-state gas conveying, the compressed air supply is stable, with stable pressure and flow rate. In pulsed gas conveying, the compressed air supply in the conveying pipeline is unstable and constantly changes over time, with pressure and flow rate fluctuating. Compressed gas is supplied to the conveying pipeline in pulses.

[0003] Current pulse gas conveying equipment is complex in structure, and most utilize a pressure-limiting valve. When the pressure inside the gas bag exceeds the set pressure, the pressure-limiting valve opens, supplying gas to the conveying pipeline. When the pressure inside the gas bag falls below the set pressure, the pressure-limiting valve closes, depriving the pipeline of gas. This gas supply method results in long pulse cycles, low pulse frequency, and poor pulse efficiency, leading to a high rate of equipment failures during powder conveying and hindering normal production. Therefore, a pulse gas generator has been proposed to address these issues. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-6 The utility model discloses a pulse gas generator, comprising:

[0035] A tube body 1, wherein the tube body 1 is provided with an air inlet end 11 and an air outlet end 12;

[0036] The isolating portion 2 is provided in the tube body 1 and is provided with a first communicating portion 21 and a second communicating portion 22 communicating with the air inlet end 11 and the air outlet end 12;

[0037] The regulating part 3 includes two sets of blocking pieces 31 respectively provided at both ends of the isolation part 2, and the two sets of blocking pieces 31 are used for alternately exhausting and supplying air;

[0038] The adjusting portion 3 further includes a deflection tension spring 33 fixedly connected to the blocking piece 31 and a transmission portion connecting the two groups of blocking pieces 31;

[0039] The deflection tension spring 33 and the transmission part are used to synchronously drive the two groups of blocking pieces 31 to deflect when the internal air pressure of the first connecting part 21 or the second connecting part 22 is greater than the tension of the deflection tension spring 33 to perform gap exhaust.

[0040] It should be noted that the two groups of blocking pieces 31 act alternately on the first communicating portion 21 and the second communicating portion 22 to connect the air inlet end 11 to the first communicating portion 21 or the second communicating portion 22 .

[0041] In this application, specifically, Figure 5-6 As shown, the adjusting portion 3 includes a connecting rod 32 , and two sets of hinge rods 34 are respectively provided at both ends of the connecting rod 32 ;

[0042] The two groups of blocking pieces 31 are respectively arranged on the hinged rods 34 at both ends;

[0043] The deflection tension spring 33 is provided on the connecting rod 32 , and one end of the deflection tension spring 33 is connected to the connecting rod 32 , and the other end of the deflection tension spring 33 is connected to the blocking piece 31 ;

[0044] The transmission part is disposed in the connecting rod 32 to synchronously drive the two sets of hinged rods 34 to swing in opposite directions.

[0045] In the present application, it is also necessary to add that the transmission portion includes a transmission rod 35 that passes through the connecting rod 32, and driven bevel gears are provided at both ends of the transmission rod 35;

[0046] The two sets of hinged rods 34 are provided with transmission bevel gears 341;

[0047] The two groups of transmission bevel gears 341 are respectively distributed on opposite sides of the two groups of driven bevel gears.

[0048] Through the above-mentioned structural arrangement, when the blocking piece 31 near the air outlet end 12 swings under the action of pressure, the hinged rod 34 can be driven to rotate, and the transmission bevel gear 341 provided on the hinged rod 34 is engaged with the transmission rod 35, thereby driving the blocking piece 31 on the other side to perform synchronous action. By distributing the two groups of the transmission bevel gears 341 on the opposite sides of the two groups of driven bevel gears respectively, the effect of the two groups of blocking pieces 31 swinging in opposite directions can be achieved, thereby achieving the purpose of alternately blocking the first communicating portion 21 and the second communicating portion 22.

[0049] In the present application, the air inlet end 11 of the tube body 1 is connected to the output end of the air compressor, and the air outlet end 12 is connected to the target pipeline. When in use, the blocking piece 31 connects the first communicating portion 21 and closes the second communicating portion 22. Air enters the first communicating portion 21 through the air inlet end 11, and the outlet of the first communicating portion 21 is blocked by the blocking piece 31 on the other side. Therefore, compressed air continues to enter the first communicating portion 21 until the internal air pressure of the first communicating portion 21 is greater than the tension of the deflection tension spring 33. At this time, the blocking piece 31 is blown open and, at the same time, deflected to the other side under the action of the deflection tension spring 33. At this time, due to the setting of the transmission part, the two groups of blocking pieces 31 are deflected synchronously. Therefore, the first communicating portion 21 is closed, and the second communicating portion 22 is connected. At the same time, the outlet of the second communicating portion 22 is also blocked by the blocking piece 31. The above steps are repeated to generate pulse gas.

[0050] In the above process, it should also be noted that, since two sets of deflection springs 33 are provided, the internal air pressure of the first connecting portion 21 or the second connecting portion 22 needs to be greater than the tension of the two sets of deflection springs 33. In one embodiment, the deflection spring 33 can be provided only on the blocking piece 31 near the air outlet end 12.

[0051] It should be added that, in the present application, a deflection spring 33 may be provided at the upper position of the connecting rod 32 , thereby deflecting the tension of the spring 33 , increasing the gas pressure required to break open the blocking piece 31 , and thereby adjusting the intensity of the pulse gas.

[0052] It should be noted that a sealing gasket is provided on the blocking piece 31 , and the sealing gasket corresponds to the first connecting portion 21 and the second connecting portion 22 to improve air tightness and prevent gas from overflowing and affecting the internal pressure of the first connecting portion 21 and the second connecting portion 22 .

[0053] In the present application, the blocking piece 31 close to one end of the air inlet end 11 is used to conduct the first connecting portion 21 or the second connecting portion 22;

[0054] The blocking piece 31 close to one end of the air outlet 12 is used to block the air outlet of the first connecting portion 21 or the second connecting portion 22 that is connected.

[0055] In summary, the present application can continuously supply air to the air inlet end 11 through compressed gas, and make the first connecting part 21 or the second connecting part 22 alternately conductive by increasing the air pressure, thereby generating a pulse airflow and discharging it through the air outlet end 12 without the need for additional external power assistance, thereby achieving the effect of automatically generating a pulse airflow.

[0056] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).
