[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] The filters configured in metallurgical production lines are mostly used to filter impurities in water. When the solid filter material in the filter is fed vertically, the manual opening and closing of the feed port by the commonly configured horizontal plug plate is inconvenient and labor-intensive, and the filter material with a certain volume and weight is easy to squeeze and splash the on-site operators on the machine.

[0036] The rotating support 4 is arranged on the hopper 1 through the bracket 3, and the rotating rod 5 is rotatably arranged on the rotating support 4. The first ends of the operating handle 6 and the first connecting rod 7 are respectively connected to the rotating rod 5, so that the rotating rod 5 can be driven to rotate by pushing the operating handle 6, thereby driving the first connecting rod 7 to deflect about the central axis of the rotating rod 7; the first end of the second connecting rod 8 is pivotally connected to the second end of the first connecting rod 7, and the second end of the second connecting rod 8 is pivotally connected to the blocking bucket 2, so that a multi-link structure can be formed by the first connecting rod 7 and the second connecting rod 8 to drive the blocking bucket 2 to deflect, so that the connecting rod structure can be used to realize labor-saving driving of the blocking bucket 2, thereby reducing the difficulty of manually opening and closing the discharge port 11 to a certain extent, and improving the operating efficiency; on the other hand, since the multi-link structure is adopted, the operator can open and close the discharge port 11 away from the discharge port 11, thereby reducing the risk of filter material splashing and injuring people from the discharge port 11 to a certain extent, and improving the operating safety.

[0037] In some embodiments, in order to stably install the rotating rod 5 and maintain the smoothness of its rotation, the rotating support 4 may include more than two bearings, and the two or more bearings may be arranged on the bracket 3 at intervals along the length direction of the rotating rod 5.

[0038] In some embodiments, the blocking bucket 2 may include an arc-shaped baffle 21 and two connecting plates 22; the two connecting plates 22 are relatively connected to the two sides of the arc-shaped baffle 21 to form a U-shaped bucket, and the two connecting plates 22 are pivotally connected to the hopper 1 through a pivot shaft 23, and the deflection stroke of the arc-shaped baffle 21 covers the discharge port 11 of the hopper 1 to deflect and block the discharge port 11 of the hopper 1.

[0039] In some embodiments, the connecting plate 22 can be set as a fan-shaped plate, the center end of the fan-shaped plate is pivotally connected to the hopper 1, the arc end of the fan-shaped plate is matched and connected to the arc baffle 21, and the fan-shaped plate is pivotally connected to the second end of the second connecting rod 8, thereby ensuring the fixed reliability of the arc baffle 21 and the simple connection structure, reducing the risk of interference.

[0040] In some embodiments, the lower edge of the discharge port 11 of the hopper 1 is configured to be an arc shape that matches the arc baffle 21 , thereby improving the sealing performance of the arc baffle 21 .

[0041] In some embodiments, the operating handle 6 is disposed at an end away from the hopper 1 , further increasing the distance from the operating handle to the discharge port 11 .

[0042] In some embodiments, a guide slope 15 is provided inside the hopper 1, and the angle between the guide slope 15 and the vertical direction is less than 30 degrees, thereby increasing the rate of filter material discharge and reducing the risk of accumulation.

[0043] In some embodiments, in order to facilitate efficient handling when a blockage occurs, an observation window 13 may be opened on the side of the hopper 1 for easy observation, and the operating window 13 may be used to handle the congested part through a fork or the like.

[0044] In some embodiments, in order to facilitate the transportation of the hopper 1 , a lifting lug 12 may be provided on the hopper 1 .

[0045] In some embodiments, a support column 14 is provided on the hopper 1 to provide stable support.
