[0018] As Figs. 1-3 Shown, a kind of device of self -closing pressurization unloading of air extraction, unloading pipe 1 lower end extends to inside through collecting pipe 3 top, and unloading pipe 1 lower end opening position is connected with outer duckbill type rubber tube 2, and collecting pipe 3 one side is equipped with air extraction butt joint 301, and outer duckbill type rubber tube 2 lower end extends position exceeds air extraction butt joint 301.

[0019] Utilize the special performance of the outer duckbill type rubber tube 2 of one end flat, one end is the round mouth silica gel pipe, and the round mouth is installed on pipeline upwards, and flat mouth is downwards, because of the elasticity of silica gel itself, cause flat mouth to close, realize the automatic locking of outlet under the condition of material, if bag dust collector is in the state of air extraction, flat mouth is more closely, with the nitrogen backflush of bag dust collector, air extraction state is destroyed, and the dust collected in outer duckbill type rubber tube 2 gathers due to self weight and reverse pressure caused by backflush, cause outer duckbill type rubber tube 2 flat mouth to open, and dust collected falls;With the end of backflush, outer duckbill type rubber tube 2 closes, and closes the passage, and realizes perfect dust removal effect again, when next time backflush, and the collected dust is cleaned in time.

[0020] Air extraction butt joint 301 can be used for air extraction or for overhauling outer duckbill type rubber tube 2.

[0021] In the preferred embodiment, the outer duckbill rubber tube 2 is sleeved at the lower end opening position of the discharge pipe 1. The outer circle of the outer duckbill rubber tube 2 is provided with a plurality of groove bodies, and the groove bodies are internally provided with locking bands 5. The locking bands 5 are used to fix the outer duckbill rubber tube 2 at the lower end opening position of the discharge pipe 1.

[0022] Sleeving and fixing: The outer duckbill rubber tube 2 is directly sleeved at the lower end opening position of the discharge pipe 1.

[0023] In order to ensure that the outer duckbill rubber tube 2 can be firmly installed on the discharge pipe 1, a plurality of groove bodies are designed on the outer circle thereof.

[0024] Application of locking bands 5: Each groove body is internally provided with a locking band 5. The locking bands 5 are used to tightly fix the outer duckbill rubber tube 2 at the lower end opening of the discharge pipe 1.

[0025] The locking bands 5 are embedded in the groove bodies, thereby providing additional mechanical fixation to prevent the outer duckbill rubber tube 2 from loosening or falling off during work.

[0026] This design not only ensures the stable installation of the outer duckbill rubber tube 2, but also improves the working efficiency and reliability of the entire air suction self-closing pressurized discharge device.

[0027] In the preferred embodiment, a protruding limiting ring 102 is arranged at the outer circle of the lower end opening position of the discharge pipe 1, and the locking bands 5 are clamped above the limiting ring 102. A protruding limiting ring 102 is arranged at the outer circle of the lower end opening position of the discharge pipe 1.

[0028] The locking bands 5 are clamped above the limiting ring 102, thereby further enhancing the fixing effect of the outer duckbill rubber tube 2 and ensuring that it can remain stable when bearing the weight of the material and the pressure change.

[0030] In the preferred embodiment, an inner duckbill rubber tube 7 is additionally arranged inside the upper end opening position of the discharge pipe 1, and the inner duckbill rubber tube 7 is coaxially arranged with the outer duckbill rubber tube 2. In order to prevent the outer duckbill rubber tube 2 from being blocked, thereby causing the closure to be not tight enough, the inner duckbill rubber tube 7 is additionally arranged inside the upper end opening position of the discharge pipe 1, thereby playing a double insurance role. This design not only improves the reliability of the system, but also effectively avoids the problem of material blockage, thereby ensuring that the outer duckbill rubber tube 2 can normally and automatically open and close, and thereby maintaining the efficient operation of the entire air suction self-closing pressurized discharge device.

[0031] In the preferred embodiment, the mounting ring 701 of the outer duckbill hose 2 is arranged between the discharge pipe 1 and the mating interface 6, and the mounting ring 701 is pressed by the flange. When the upper end opening of the discharge pipe 1 is connected to the mating interface 6 through the mating flange 101, the mounting ring 701 is clamped between the two components, and the pressure applied by the flange ensures the stable fixation and sealing performance of the inner duckbill hose 7. This design not only ensures that the inner duckbill hose 7 will not displace or fall off when subjected to the gravity of the material and the internal pressure, but also enhances the sealing performance of the entire connection part, prevents material leakage or external air from entering the system, and thus ensures the high efficiency and reliability of the air suction self-closing pressurized discharge device.

[0032] In the preferred embodiment, the lower end of the collecting pipe 3 is of a tapered structure, and a flange mating disc is arranged at the lower end opening position. The tapered design of the lower end of the collecting pipe 3 can effectively guide the material to be discharged in a concentrated manner, reduce the residue of the material in the pipe, and also help to improve the flow speed of the material, ensuring a smoother discharge process.

[0033] In the preferred embodiment, the material of the outer duckbill hose 2 or the inner duckbill hose 7 is silicone or rubber. The selection of silicone or rubber as the material of the outer duckbill hose 2 and the inner duckbill hose 7 can not only ensure the automatic opening and closing of the hose under the action of pressure or the gravity of the material, but also prevent material leakage and external air from entering the system, thereby ensuring the high efficiency and reliability of the entire air suction self-closing pressurized discharge device. This material selection provides a flexible application range for the device, which is suitable for different working conditions and environmental requirements.
