[0008] Further, one end of the fixing piece is provided with a flange fixedly connected with the gas lock shell, and the other end is provided with a clamping head connected with the moisture discharge pipeline.
[0009] Through the above further scheme, the flange connection can ensure the stable connection between the fixing piece and the gas lock shell, prevent gas leakage, and can withstand high pressure. The clamping head can be quickly connected with the moisture discharge pipeline through the clamp.
[0010] Further, the silencing mechanism comprises a filter screen and a cylinder, the cylinder is hollow inside and open at both ends, the filter screen is fixedly installed on one end of the cylinder, and a screw rod for connecting with the fixing member is rotatably connected to the other end of the cylinder.
[0011] Through the above further scheme, the filter screen not only blocks the material from entering the moisture removal pipeline, but also attenuates the high-frequency noise in the airflow. When the gas passes through the filter screen, the sound waves are scattered and absorbed by the mesh, thereby reducing the noise intensity.
[0012] Further, the cylinder connecting screw rod one end and located on both ends of the cylinder diameter are provided with installation table, the installation table is rotatably connected with the screw rod, and the screw rod is provided with a clamping groove opposite to the installation table.

[0016] Further, the filter screen is flush with the inner wall of the airlock shell.
[0017] Through the above further scheme, since the airlock shell is provided with a rotor for transporting material, the filter screen cannot protrude from the inner wall of the airlock shell. When the filter screen is lower than the inner wall of the airlock shell, a groove is formed, so that the material will accumulate in the groove, thereby blocking the filter screen. When the filter screen is flush with the inner wall of the airlock shell, the rotor can also play a scraping role on the filter screen, avoiding material blockage of the filter screen.
[0018] Further, the filter screen is arc-shaped, and the curvature of the filter screen is the same as the curvature of the inner wall of the airlock shell.
[0019] Through the above further scheme, the filter screen coincides with the inner wall of the airlock shell, that is, it does not affect the transportation of the material, and can also ensure the scraping of the rotor on the filter screen.
[0020] Further, a nut is threadedly connected to the screw rod, and the nut is located opposite to the side of the boss towards the cylinder.
[0021] Through the above further scheme, the nut can further fix the screw rod and play a positioning role.
[0022] Further, the outer side of the cylinder is attached to the inner side of the moisture discharge port.
[0023] Through the further scheme, the material is prevented from entering the moisture discharge pipeline between the moisture discharge port and the cylinder.
[0024] In summary, the air lock silencer has the following technical effects:
[0025] 1. The moisture discharge port and the moisture discharge pipeline are connected end to end through the fixing member, so that the stability and sealing performance of the structure are ensured, gas leakage is prevented, and the silencing effect is ensured through the silencing mechanism in the fixing member.
[0026] 2. The silencing mechanism can prevent the material in the air lock shell from being sucked into the moisture discharge pipeline, so that the material waste and the blockage of the moisture discharge pipeline are prevented. BRIEF DESCRIPTION OF DRAWINGS

[0039] Wherein, the outside of cylinder 32 is attached to the inside of moisture discharge port 11, to prevent material from entering the moisture discharge pipeline between moisture discharge port 11 and cylinder 32.
[0040] The mounting platform 321 facilitates the installation of the screw 4 and provides a support point for the screw 4.
