Therefore, corresponding improvements are made to this problem, and an anti-blocking boiler feed pipe is proposed. Utility Model Content

After the pipe body 1 is blocked, the connecting plate 4 can be rotated by the handle 5, and the connecting plate 4 can synchronously drive the main shaft 2 and the rotating plate 3 to rotate, so that the coal slag blocked in the pipe body 1 can be cleared by the rotating plate 3, thereby avoiding blockage of the feed pipe.

[0026] Furthermore, the positioning assembly includes an insertion rod 7, a hole 6 is opened on the connecting plate 4, a sleeve 8 is fixed on the tube body 1, the insertion rod 7 passes through the hole 6 and is inserted into the sleeve 8. Under normal conditions, the insertion rod 7 is inserted into the hole 6 and the sleeve 8, so that the rotating plate 3 can be fixed in a vertical state.

[0027] Furthermore, a blocking rod 9 is provided in the tube body 1 and is located above the rotating plate 3. A plurality of groups of support rods 12 distributed up and down are fixed on the blocking rod 9. A connecting rod 10 is fixed in the tube body 1. A sleeve 11 is fixed at the other end of the connecting rod 10. The sleeve 11 is sleeved on the blocking rod 9. Both ends of the rotating plate 3 are arc-shaped structures, and the bottom end of the blocking rod 9 is a spherical structure. When the rotating plate 3 rotates, the end of the rotating plate 3 acts on the bottom end of the blocking rod 9, and the blocking rod 9 moves upward, and then moves downward under the action of gravity, and this process is repeated. Therefore, more parts of the tube body 1 can be blocked at the same time through the blocking rod 9 and the support rods 12, thereby improving the blocking effect.

[0028] Furthermore, arc-shaped positioning grooves 15 are provided in the middle positions of both ends of the rotating plate 3. In the initial state, the bottom end of the blocking rod 9 is just located in the positioning groove 15, so that the blocking rod 9 is stabilized.

[0031] Furthermore, a spring 18 is fixed to the bottom end of the slider 17, and the other end of the spring 18 is fixed to the bottom inner wall of the slide groove 16. The spring 18 can provide buffering, thereby reducing noise.

[0032] Working principle: Under normal conditions, the plug rod 7 is inserted into the socket 6 and the socket 8, so that the rotating plate 3 can be fixed in a vertical state, so that the pipe body 1 will not be blocked. After the pipe body 1 is blocked, the connecting plate 4 can be rotated by the handle 5, and the connecting plate 4 synchronously drives the main shaft 2 and the rotating plate 3 to rotate, so that the cinders blocked in the pipe body 1 can be cleared by the rotating plate 3, thereby avoiding blockage of the feeding pipe;

[0033] When the rotating plate 3 rotates, the end of the rotating plate 3 acts on the bottom end of the blocking rod 9, and the blocking rod 9 moves upward, and then moves downward under the action of gravity, and repeats this process, so that more parts of the pipe body 1 are blocked at the same time through the blocking rod 9 and the support rod 12, thereby improving the blocking effect;

[0034] When the blocking rod 9 moves up and down, the cooperation between the annular groove 13 and the fixed ball 14 can make the blocking rod 9 rotate, thereby improving the blocking effect;

[0035] Through the sliding cooperation between the slide groove 16 and the slider 17, the blocking rod 9 can be stably moved in the up and down directions, and the spring 18 can be used for buffering, thereby reducing noise.
