[0004] The utility model has the advantages of simple structure, safety and reliability, and good application prospect.

[0005] However, the current construction tools have the following problems: the dirt on the inner wall of the sewage pipe cannot be cleaned, which will cause the sewage pipe to be blocked, affecting the smooth operation of the sewage system, and even causing overflow or backflow. Therefore, we proposed an automatic sewage discharge device for a steam generator. Utility Model Content

On the trajectory, the outer wall of the T-shaped scraper block contacts the inner wall of the sewage pipe. There are multiple T-shaped scrapers, and they are arranged in a circular array on the circumferential surface of the rotating shaft. The motor is started, and the output shaft of the motor causes the rotating shaft to rotate. The rotation of the rotating shaft drives the T-shaped scraper block to rotate, and the dirt on the inner wall of the sewage pipe is cleaned.

During the rotation, the protrusion 1 will contact the protrusion 2, so that the U-shaped moving rod moves. The movement of the U-shaped moving rod will drive the fixed block to move, the movement of the fixed block will drive the rotating rod to move, and the movement of the rotating rod will drive the guide plate to rotate on the circumferential surface of the fixed rod.

[0009] The utility model provides an automatic sewage discharge device for a steam generator, which has the following beneficial effects:

[0010] (1) The utility model cooperates with the impact plate, the U-shaped block, the C-shaped block, the resistance plate, the elastic plate and the T-shaped scraper block so that when the impact plate does not resist the resistance plate, the elastic plate will rebound due to its own elasticity. The rebound of the elastic plate will knock the outer wall of the C-shaped block, thereby helping the T-shaped scraper block to more effectively peel off the tightly attached dirt or sediment from the wall of the sewage pipe, reduce the risk of the T-shaped scraper block getting stuck, and maintain the normal working state of the scraper block and the sewage pipe.
