Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments.

[0019] Figure 1 The present invention discloses a self-cleaning air knife baffle device for slag buildup, comprising a base 1, a baffle seat 2, an air knife baffle 3, a side rail 4, a horizontal rail 5, an air inlet pipe 6, a main pipe 7, a bypass pipe 8, and an air outlet pipe 9; the base 1 is disposed on the top of the air knife baffle.

[0020] Figure 1 and Figure 2 The air knife stop wheel 3 is rotatably connected to the front end of the stop wheel seat 2; two side rails 4 are symmetrically fixed to the two sides of the base 1 by bolts, and two horizontal rails 5 are symmetrically fixed to the two sides of the bottom surface of the base 1. The stop wheel seat 2 is slidably connected to the two side rails and the two horizontal rails respectively.

[0021] Figure 3 The display shows that a screw 12 is provided on the retaining wheel seat 2. The screw 12 is horizontal and perpendicular to the axis of the air knife retaining wheel 3. A rotating wheel 13 is threadedly connected to the screw 12. When the rotating wheel 13 is rotated, the retaining wheel seat 2 slides along the horizontal rail 5 and the side rail 3.

[0022] Figure 1 The main pipeline 7 and the bypass pipeline 8 are connected in parallel. The two ends of the main pipeline 7 are connected to the air inlet pipeline 6 and the air outlet pipeline 9, respectively. The air outlet pipeline 9 is fixedly connected to the side rail 4 by two pipe clamps 16. The outlet of the air outlet pipeline 9 is equipped with a nozzle 11. The nozzle 11 is located above the air knife baffle wheel 3 and faces the wheel surface of the air knife baffle wheel 3, ensuring that the gas sprayed by the nozzle 11 can clean the slag on the wheel surface of the air knife baffle wheel 3 in real time.

[0023] Figure 1 The diagram shows that an air filter 14 and a pressure reducing valve 15 are installed adjacent to each other on the main pipeline 7, and two ball valves 10a and 10b are installed on the main pipelines on both sides of the air filter 14 and the pressure reducing valve 15, respectively; a ball valve 10c is installed on the bypass pipeline 8.

[0024] In normal production, the air inlet end of the air inlet pipe 6 is connected to the main compressed air network of the workshop. The ball valve 10c on the bypass pipe 8 is closed, and the two ball valves 10a and 10b on the main pipe 7 are open. After being filtered by the air filter 14 and reduced in pressure by the pressure reducing valve 15, the compressed air is sprayed onto the air knife retainer wheel 3 through the nozzle 11 installed at the outlet of the air outlet pipe 9, thus preventing slag buildup on the wheel surface of the air knife retainer wheel 3. During production, when the air filter 14 on the main pipe 7 becomes clogged and needs to be cleaned, the ball valve 10c on the bypass pipe 8 is opened first, and then the two ball valves 10a and 10b on the main pipe 7 are closed in sequence. This allows the filter element of the nozzle 11 to be replaced without stopping the air supply, thus preventing slag buildup on the air knife retainer wheel 3 due to intermittent air supply. When slag inevitably forms on the air knife baffle wheel 3 after prolonged use, the baffle wheel seat 2 can be slid along the side rail 4 and horizontal rail 5 by rotating the wheel 12, thereby moving the air knife baffle wheel 3 away from the nozzle 11 and facilitating offline cleaning of the slag on the surface of the air knife baffle wheel 3.
