Technical Field

[0001] This utility model relates to the field of unclogging nozzle technology, and more specifically, to a pneumatic duckbill-type anti-clogging nozzle applied to powder silos. Background Technology

[0002] A powder silo is a container or device specifically designed for storing and transporting powder materials. It is widely used in many industries such as pharmaceuticals, food, energy, plastics, mineral and metal powders, new energy, ceramics, and chemicals to protect and transport powder materials and ensure the continuity and stability of the production process.

[0003] In the prior art, during the feeding process, powder materials tend to adhere to the inner wall of the nozzle due to their high viscosity and moisture content, causing the nozzle to become clogged and unable to be used normally, thus preventing the powder materials from being fed normally.

[0035] Example 1

[0036] Please refer to Figure 1-6A pneumatic duckbill-type anti-clogging nozzle for powder silos includes a nozzle body 1. A flange 11 is fixedly connected to the lower surface of the nozzle body 1. A protective component for preventing material from entering the nozzle body 1 is fixedly connected to the right side of the nozzle body 1. A reset component is fixedly connected to the center of the right side of the nozzle body 1. A movable groove 4 is formed on the upper surface of the nozzle body 1, and a fixing component is slidably connected to the inner surface of the movable groove 4. The protective component includes mounting plates 2. Two mounting plates 2 are fixedly arranged on the right side of the nozzle body 1. A mounting block 21 is rotatably connected between the two mounting plates 2 via a rotating shaft. A protective plate 22 is fixedly connected to the outer surface of the mounting block 21. A slot 23 is formed on the left side of the protective plate 22. The fixing components include a locking block 41 and a rotating plate 48. A connecting plate 42 is fixedly connected to the left side of the protective plate 22. A locking groove 43 is formed on the outer surface of the connecting plate 42. The locking block 41 is slidably disposed inside the movable groove 4 and the locking groove 43 respectively. A movable groove 44 is formed inside the nozzle body 1 on one side of the movable groove 4. A movable plate 45 is slidably connected to the inner surface of the movable groove 44. A spring 46 is fixedly connected between the movable plate 45 and the movable groove 44. A movable groove 47 is formed inside the nozzle body 1 between the movable groove 4 and the movable groove 44. One end of the rotating plate 48 is rotatably connected to the locking block 41 through a rotating shaft, and the other end of the rotating plate 48 is rotatably connected to the movable plate 45 through a rotating shaft. The rotating plate 48 is movably disposed inside the movable groove 47. The upper surface of the locking block 41 is curved.

[0037] Implementation process: When the silo needs to be cleaned, the gas flows from the bottom of the nozzle body 1 to the right side of the nozzle body 1. During the gas flow, the movable plate 45 slides to the right inside the movable groove 44 and compresses the spring 46. The movement of the movable plate 45 causes the rotating plate 48 to rotate, thereby causing the locking block 41 to move downward and disengage from the groove 43. Then the gas pushes the protective plate 22 and the mounting block 21 to rotate clockwise, causing the protective plate 22 to separate from the outlet of the nozzle body 1. Then the gas clears the material inside the silo. The opening of the groove 23 reduces the air pressure required for the protective plate 22 to rotate. During the rotation of the protective plate 22, the rotating plate 35 rotates, thereby causing the slider 33 to slide downward inside the groove 31 and compress the spring 32. During the sliding of the slider 33, the sealing plate 36 slides synchronously to prevent dust from entering the groove 31 and causing blockage.

[0038] Benefits of implementation: It enables the flow of gas through the material inside the silo.

[0039] Example 2

[0040] The reset component includes a second mounting plate 3 and a first rotating plate 35. The second mounting plate 3 is fixedly connected to the right side of the nozzle body 1. A groove 31 is formed on the right side of the second mounting plate 3. A spring 32 is fixedly connected to the lower side of the inner surface of the groove 31. A slider 33 is fixedly connected to the upper end of the spring 32. The slider 33 slides inside the groove 31. A second mounting block 34 is fixedly connected to the upper side of the right side of the protective plate 22. One end of the first rotating plate 35 is rotatably connected to the slider 33 via a rotating shaft, and the other end of the first rotating plate 35 is rotatably connected to the second mounting block 34 via a rotating shaft. Sealing plates 36 are fixedly connected to both the upper and lower sides of the outer surface of the slider 33.

[0041] Implementation process: After the gas delivery stops, the movable plate 45, under the elastic force of the second spring 46, drives the second rotating plate 48 and the locking block 41 to reset. Then, the slider 33 slides upward under the elastic force of the first spring 32, causing the first rotating plate 35 to rotate. At the same time, the protective plate 22 and the mounting block 21 rotate counterclockwise to reset, preventing material from entering the nozzle body 1. During the rotation of the protective plate 22, the connecting plate 42 rotates synchronously. The connecting plate 42 contacts the curved surface of the locking block 41 and pushes the locking block 41 to move downward inside the movable groove 4. The movement of the locking block 41 causes the second rotating plate 48 to rotate, thereby pushing the movable plate 45 to slide to the right inside the movable groove 44 and compressing the second spring 46. Then, under the elastic force of the second spring 46, the movable plate 45 drives the locking block 41 to move upward, causing the locking block 41 to slide into the interior of the connecting plate 42, thereby fixing the connecting plate 42 and the protective plate 22 and preventing the material from pushing the protective plate 22 to rotate during the falling process.

[0042] Benefits of implementation: The nozzle body 1 is sealed by the protective plate 22 to prevent dust and materials from entering the interior of the nozzle body 1.
