Technical Field

[0001] The utility model relates to the technical field of sewage discharge devices, in particular to a novel steam turbine operation sewage discharge device. Background Art

[0002] After the steam turbine has been running for a long time, the circulating water in its condenser circulating water cooling tower circulates in a closed system. The long-term circulation causes the circulating water to be concentrated, and the proportion of organic impurities and inorganic salts in the circulating water increases. These organic impurities and inorganic salts will scale in the condenser copper tubes, resulting in a decrease in the thermal efficiency of the unit. Therefore, it is necessary to regularly discharge the circulating water in the condenser circulating water cooling tower.

[0003] After searching, the Chinese patent with the patent announcement number CN215855583U discloses a new type of steam turbine operation sewage discharge device, including a treatment box, a purification box is arranged on the right side of the treatment box, and a water inlet pipe and a drain pipe are arranged on the left side of the treatment box and the lower surface of the purification box respectively, and the surfaces of the water inlet pipe and the drain pipe are both provided with electromagnetic valves, the inner wall of the treatment box is slidably connected with a sliding frame, the inner wall of the sliding frame is fixedly installed with a filter membrane, the upper surface of the treatment box is embedded with a mounting frame, and the inner top wall of the mounting frame is rotatably connected with a lead screw. The new type of steam turbine operation sewage discharge device can drive the lead screw to rotate through the rotation of the driving motor when treating the circulating water discharged from the condenser circulating water cooling tower, and the rotation of the lead screw drives the sliding frame to move downward through the threaded barrel, so that the filter membrane pressurizes and filters the circulating water, and the filtered circulating water enters the purification box through the water pump, and at the same time, the filtered debris can be discharged through the sealed sewage discharge door, which improves environmental awareness.

[0004] However, the above design still has some shortcomings. The above design does not have the function of disassembling and cleaning the filter mechanism. After long-term use, the filter mechanism will be blocked, which will affect the flow of circulating water and the use effect is poor. Utility Model Content

After cleaning, the filter frame 7 is placed in front of the processing box 1, and the sliding block 14 is aligned with the sliding slot 15, and then the filter frame 7 is pushed into the processing box 1, and the movement of the filter frame 7 drives the limit block 805 to move. When the limit block 805 moves to the opposite side of the limit hole 804, the spring 802 is no longer subjected to external force, and it will drive the limit block 805 to insert into the limit hole 804, thereby completing the fixation of the sliding block 14, and then completing the installation of the filter frame 7.
