[0002] The return air duct of the batching silo is a component of the batching silo system.

[0003] Return air ducts can expel dust and moisture generated during the batching process from the batching silo, keeping the air inside the silo fresh and dry, which helps prevent materials from getting damp, clumping, or deteriorating.

[0004] The return air duct can be used to adjust the airflow speed and direction in the batching bin, ensuring the uniform distribution and smooth flow of materials during the batching process.

[0005] Return air ducts are typically connected to dust collection systems to collect and treat exhaust dust, preventing it from harming the environment and operators.

[0006] However, existing return air ducts are prone to leaks due to poor sealing at the joints during installation, which affects the return air supply.

[0007] Therefore, it is essential to invent a return air duct for the ingredient storage bin. Utility Model Content

[0025] Example

[0026] Reference Figure 1-4 A batching silo return air duct includes a corrugated return air duct 1, wherein: each end of the corrugated return air duct 1 is fixedly installed with a plug plug, the plug plug is connected to the corrugated return air duct 1, three fasteners are threadedly installed on the plug plug, the plug plug is plugged into and connected to a connector 10 on a suction pipe 9, several sealing rings are provided between the plug plug and the connector 10, and the plug plug and the connector 10 are fixed by fasteners. With this structure, after the plug plug is inserted into the connector 10, the plug plug and the connector 10 can be fixedly connected by fasteners, thereby ensuring their stability and facilitating disassembly and assembly.

[0027] Specifically, the plug includes an outer sleeve 2 and an inner sleeve 3. The inner sleeve 3 is coaxially fixed inside the outer sleeve 2, forming an annular cavity between the inner sleeve 3 and the outer sleeve 2. One end of the outer sleeve 2 is fixedly connected to one end of the corrugated return air pipe 1. The outer sleeve 2 is not connected to the inside of the corrugated return air pipe 1, while the inner sleeve 3 is connected to the inside of the corrugated return air pipe 1. Sealing rings are fixedly installed on the inner surface of the outer sleeve 2 and the outer surface of the inner sleeve 3, respectively. Fasteners are installed on the outer sleeve 2 by threads. The outer sleeve 2 is fitted on the outer surface of the connector 10, and the inner sleeve 3 is inserted inside the connector 10. Through the arrangement of the outer sleeve 2 and the inner sleeve 3, a double seal can be formed between them, improving the sealing performance of the connection and preventing leakage.

[0028] The outer sleeve 2 and the inner sleeve 3 are made of metal tubing.

[0029] Specifically, the outer sleeve 2 has at least one threaded hole 6 on its surface. The threaded hole 6 is connected to the annular cavity. The fastener is installed in the threaded hole 6. The threaded hole 6 can limit the position of the fastener and facilitate the adjustment of the fastener.

[0030] Specifically, the sealing ring includes an elastic sealing ring 4 and an elastic sealing ring 5. Several elastic sealing rings 4 are evenly distributed on the inner surface of the outer sleeve 2 and are coaxial with the outer sleeve 2. Several elastic sealing rings 5 ​​are evenly distributed on the outer surface of the inner sleeve 3 and are coaxial with the inner sleeve 3. The elastic sealing rings 4 and 5 do not contact each other. The elastic sealing ring 4 is fitted onto the outer surface of the connector 10 to seal the space between the outer sleeve 2 and the connector 10. The elastic sealing ring 5 is located inside the connector 10 and is in close contact with the inner surface of the connector 10 to seal the space between the inner sleeve 3 and the connector 10.

[0031] The elastic sealing ring 4 and the elastic sealing ring 5 adopt existing technology, such as the rubber sealing ring in the prior art, so as to have good deformation ability, be applicable to a variety of different specifications of connectors 10, and at the same time have good friction to prevent slippage from connectors 10.

[0032] Specifically, the fastener is a bolt 7, which is installed in the threaded hole 6. The end of the bolt 7 without a nut is in the annular cavity, and the end of the bolt 7 with a nut is outside the outer sleeve 2. This allows the bolt 7 to be rotated clockwise after the outer sleeve 2 and the inner sleeve 3 are connected to the connector 10, so that the end of the bolt 7 in the annular cavity contacts the outer surface of the connector 10, thereby fixing the connector 10 to the outer sleeve 2 and the inner sleeve 3.

[0033] Specifically, an anti-detachment cap 8 is fixedly installed at one end of the bolt 7 that extends into the ring cavity. The anti-detachment cap 8 is outside the ring cavity and contacts the outer surface of the connector 10.

[0034] The anti-loosening cap 8 is made of rubber. By setting the anti-loosening cap 8, when the bolt 7 is rotating and comes into contact with the connector 10, it can prevent the bolt 7 from damaging the connector 10. At the same time, it can increase the friction between the bolt 7 and the connector 10 and prevent the bolt 7 from loosening.

[0035] In this embodiment, during use, the plug at one end of the corrugated return air pipe 1 is plugged and connected to the connector 10 on the suction pipe 9.

[0036] Specifically, the outer sleeve 2 and the first elastic sealing ring 4 are fitted onto the outside of the connector 10, and the inner sleeve 3 and the second elastic sealing ring 5 are inserted into the inside of the connector 10. At this time, the first elastic sealing ring 4 is in close contact with the outside of the connector 10, and the second elastic sealing ring 5 is in close contact with the inner surface of the connector 10, thereby preventing leakage.

[0037] Then turn the bolt 7 clockwise to make the anti-detachment cap 8 and the connector 10 make tight contact, thus completing the connection between the plug and the suction tube 9;

[0038] Finally, by using the above method, the plug at the other end of the corrugated return air duct 1 can be connected to the air outlet of the feed machine to form a return air duct.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
