[0035] The end surface where the discharge port flange 405 contacts the bearing connection flange 403 is provided with two sealing grooves, and a sealing member 7 is provided in the sealing groove, and the sealing member 7 adopts a Y-shaped sealing ring; a vent hole 8 is provided between the two sealing grooves, and an air pipe joint 9 provided at the discharge port flange 405 is sealed and connected with the vent hole 8; a movable disk 10 is provided on the right end surface of the bearing connection flange 403, and a fixed disk 11 is provided on the right side of the feed port flange close to the outer circular end surface; a plurality of groups of convex rings 12 are extended forward from the end surface where the movable disk 10 and the fixed disk 11 are in contact, and the convex rings 12 extend into the grooves 13 provided on the fixed disk 11, so that the movable disk 10 and the fixed disk 11 are sealed and connected to form a labyrinth seal, and the labyrinth seal is S-shaped.
[0036] In this embodiment, the discharge port welding flange 402 is connected to the discharge port set in the cylinder 2, wherein seals 7 are arranged in the two sealing grooves arranged on the end surface where the discharge port flange 405 contacts the bearing connecting flange 403, and the seal 7 contacts the inner cylindrical surface of the bearing connecting flange 403 to form a contact seal, and at the same time, the air pipe joint 9 injects controlled compressed air into between the two sealing rings through the vent 8 to form an air seal, and the movable disk 10 set in the bearing connecting flange 403 is sealed and connected with the fixed disk 11 set in the discharge port flange 405, so that a multiple sealing structure is formed through the above structure, which plays a role in blocking materials and solves the problem of material leakage.

[0037] Furthermore, a discharge port guide ring 14 is provided on the outer side of the cylinder 2 at the discharge port, and the discharge port guide ring 14 is connected to the discharge port. A retaining ring 15 is provided on the inner ring of the discharge port flange 405 close to the cylinder 2. A plurality of groups of oblique serrations are provided on the inner cylindrical surface of the retaining ring 15. The outer cylindrical surface of the discharge port guide ring 14 is in sealing contact with the lip of the oblique serrations of the retaining ring 15 to form an oblique serration type labyrinth seal.
[0038] A transition chamber 16 is formed between the discharge port welding flange 402, the fixed disk 11 and the movable disk 10. When the mixer is working, dust will be generated during feeding, stirring and unloading, and a dust mixed gas will be formed with the air in the mixer barrel 2 and the discharge hopper 401. When the dust mixed gas passes through the oblique sawtooth labyrinth seal, only a small part of the dust mixed gas passes through the lip of the oblique sawtooth, and most of the dust mixed gas will form back waves, which will form air resistance and block the dust mixed gas behind from entering. Through layers of blocking, only a small part of the dust mixed gas enters the transition chamber 16, which plays a role in blocking materials, reducing the entry of materials and alleviating the pressure of the labyrinth disk. pressure; and the dust mixed gas entering the transition chamber 16 enters through the gap between the groove 13 of the movable disk 10 and the convex ring 12 of the fixed disk 11. In the narrow gap, the mixed gas precipitates into granular material. As the movable disk 10 rotates, the material is continuously brought up, and the material rolls in the groove 13 of the movable disk 10. Under the action of gravity, the material continuously falls, and the material particles are gradually discharged, which plays a role in blocking the material, effectively preventing the sealing components from contacting with the powder material, reducing the wear of the seal 7, and at the same time preventing the material from entering the turntable bearing 404, thereby extending the service life of the turntable bearing 404, improving production efficiency, and improving the production environment.
[0039] A one-way discharger 17 is provided on the outer side of the discharge port welding flange 402, and the one-way discharger 17 is connected to the discharge hole 18 provided on the discharge port welding flange 402. When materials are accumulated in the transition chamber 16, the discharge port welding flange 402 rotates with the cylinder 2, and the materials roll on the cylindrical surface inside the discharge port welding flange 402. The materials will pass through the discharge hole 18 and enter the one-way discharger 17, so that the materials in the transition chamber 16 are emptied, thereby solving the problem of failure of the labyrinth disc seal due to excessive accumulation of materials.
[0040] An observation hole 19 is provided at a position just below the left end surface of the discharge port flange 405; leaked materials can be seen through the observation hole 19, so that the machine can be shut down for maintenance before the materials enter the turntable bearing 404, the materials on the movable plate 10 and the fixed plate 11 can be cleaned, and the sealing ring can be replaced, thereby solving the problem of wear and jamming of the turntable bearing 404 after the materials enter.
[0041] The working principle of this device is as follows: by starting the driving motor 301, the driving chain 304 drives the transmission chain 303 through the transition wheel, and the transmission chain 303 drives the cylinder 2 to rotate. When feeding, stirring and unloading, dust will be generated and form a dust mixed gas with the air in the mixer cylinder 2 and the unloading hopper 401. The pressure is set to P1. The compressed air is controlled outside the air pipe joint 9 and injected from the vent 8 to form a positive pressure cavity between the two seals 7. The lip of the left seal 7 opens due to the air pressure, and the pressure increases, the airflow is blocked, and the right seal 7 is subjected to back pressure. When the air pressure reaches a certain pressure, the airflow can pass through the right seal 7. The continuous airflow passes through the narrow gap of the labyrinth disk and is discharged into the transition cavity 16, and then discharged into the unloading hopper 401 through the retaining ring 15. The pressure is set to P2.
[0042] When P2>P1, a continuous airflow passes through a narrow gap, is discharged into the transition chamber 16 through the gap between the groove 13 of the movable disk 10 and the convex ring 12 of the fixed disk 11, and then enters the discharge hopper 401 from the gap between the material retaining ring 15 and the discharge port guide ring 14, thereby discharging the mixed gas that has not been completely precipitated, and the dusty mixed gas is blocked by the movable disk 10 and the fixed disk 11, as well as the airflow in the transition chamber 16 and cannot enter; however, air waves will be generated during feeding, stirring and unloading, the pressure in the cylinder 22 will increase instantly, and P1 will form a short-term air pressure shock wave.
[0043] When P2 < P1, part of the dust-laden mixed gas enters the transition chamber 16 through the baffle ring 15, and then enters the gap between the groove 13 of the movable disk 10 and the convex ring 12 of the fixed disk 11. In the narrow space, the mixed gas precipitates into particulate matter. As the movable disk 10 rotates, the material is continuously lifted. The material rolls in the groove 13 of the movable disk 10 and continuously drops under the action of the gravity of the object. The material particles are gradually discharged from the labyrinth disk, playing a role in blocking the material. When the blocked material accumulates in the transition chamber 16, the discharge port welding flange 402 rotates with the cylinder body 2. The material rolls on the inner cylindrical surface of the discharge port welding flange 402, and the material will enter the one-way discharger 17 through the discharge hole 18, emptying the material in the transition chamber 16.
[0044] When the seal 7 wears out, the gas seal loses its effectiveness, and the material leaks to the outer surface of the rotary table bearing 404 and is blocked by the dust-proof ring of the rotary table bearing 404. Material will flow out of the observation hole 19, and then the machine can be stopped for maintenance in time to clean the material in the gap between the groove 13 of the movable disk 10 and the protrusion of the fixed disk 11 and replace the seal 7, avoiding the wear and jamming of the rotary table bearing 404 caused by the material entering the bearing.
[0045] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the present invention.
