The two ends of the limiting angle irons 10 are respectively vertically fixed to both sides of the water outlet channel 12. The limiting angle irons play a role in reinforcing and supporting the water outlet channel and diverting and pressurizing the water outlet of the water tank.
[0030] Bearings 8 are installed at both ends of the overall component. The bearings 8 are located on the bearing base plate 1. A sealing ring 7 is provided between the bearings 8 and the bearing base plate 1. The bearing base plate 1 is fixed to the adjacent side plate 6 of the grid equipment.

[0031] Along the length of the bearing 8, a water inlet for a water tank 9 is provided on one side of the integral assembly, and an external water supply pipe 3 is connected to the water inlet via a connector B4; the other side of the integral assembly is sealed, and a swing handle 11 located outside the integral assembly is fixedly connected to the other side of the integral assembly (in the length of the bearing 8, the fixed end of the swing handle 11 extends into the interior of the other side of the integral assembly and the fixed end of the swing handle 11 is fixedly sleeved on the rotating shaft 5 on the other side of the integral assembly), so that the swing handle can drive the integral assembly to swing inside the bar screen, so that the slag on the slag receiving chute is removed by the swing and being washed by water; the swing handle 11 is used to drive the integral assembly to swing within the range of 0° to 120°.
[0032] Example 2
[0033] An internal flow unloading device is provided above the unloading trough inside the bar screen. The bar screen is provided with side plates 6 on both sides. The internal flow unloading device includes: a slag receiving chute 13, a water tank 9, a rotating shaft 5, a bearing 8, and a swing handle 11.
[0034] The slag receiving chute 13, water tank 9, and rotating shaft 5 are fixedly connected as an integral component. Part of the inner wall of the water tank 9 is enclosed with the slag receiving chute 13 to form a non-sealed internal space of the integral component. The rotating shaft 5 is located in the non-sealed internal space and is fixedly connected to one side of the slag receiving chute 13 and part of the inner wall of the water tank 9.
